The first driving device 14 includes a first motor 141, a first transmission shaft 142, a first driving pulley 143, and a first driven pulley 144. The first motor 141 may be fixedly disposed on the hanging plate 11, or may be fixed below the first conveyor belt 12 by another fixing device. The first motor 141 drives the first transmission shaft 142 to rotate, and the first transmission shaft 142 drives the first driving wheel 143 and the first driven wheel 144 to rotate, so as to drive the first conveyor belt 12 to rotate.

The first conveyor belt 12 may be implemented by a belt. The first conveyor belt 12 may be a whole belt, the width of the belt is the same as the interval distance between the hanging plates 11, and the bottom of the carrier 30 placed on the first conveyor belt 12 is in contact with the first conveyor belt 12. First conveyer belt 12 also can include two belts, and two belts set up respectively in the inboard of two link plates 11, and be parallel to each other, and the edge portion of placing carrier 30 on first conveyer belt 12 this moment contacts with the first conveyer belt 12 at both ends respectively, forms the cavity between two belts, makes the middle part of carrier 30 be unsettled state. When the first belt 12 includes two belts, the first driving device 14 includes a first motor 141, a first transmission shaft 142, two sets of first driving wheels 143 and first driven wheels 144. Two ends of the first transmission shaft 142 are respectively connected with the inner sides of the two hanging plates 11, and two ends of the first transmission shaft are respectively provided with a group of first driving wheels 143 and first driven wheels 144. The first motor 141 drives the first transmission shaft 142 to rotate, the first transmission shaft 142 drives the first driving wheels 143 at two ends to rotate, the first driving wheels 143 drive the first transmission belts 12 on the hanging plates 11 to rotate through the corresponding first driven wheels 144, and the first driven wheels 144 are used for tensioning the first transmission belts 12. The same first motor 141 and first transmission shaft 142 may ensure synchronous rotation of the two first conveyor belts 12. In addition, the first conveyor belt 12 may be implemented by rollers, chains, rollers, or conveying rollers, etc.

The plurality of pre-pressing mechanisms 13 are provided with hanging plates 11 for pressing the edge portions of the carriers 30 against the first conveyor belt 12. In one embodiment, the prepressing mechanism 13 is provided with magnetic means. The edge portion of the carrier 30 is made of a magnetic material, the magnetic component is located below the first conveyor belt 12 and presses the edge portion of the carrier 30 against the first conveyor belt 12 in an adsorption manner, or the magnetic component is located above the first conveyor belt 12 and presses the edge portion of the carrier 30 against the first conveyor belt 12 in a repulsion manner. In another embodiment, the prepressing mechanism 13 is a roller prepressing mechanism 13, and a plurality of roller prepressing mechanisms 13 are arranged at intervals along the conveying direction at the upper end of each hanging plate 11, and are used for pressing the edge portion of the carrier 30 to the first conveyor belt 12. In the above embodiment, the prepressing mechanism 13 is fixed to the carrier transport device 10.

When the first conveyor belt 12 is started, the first conveyor belt 12 and the carrier 30 have relative motion, and sliding friction force is generated between the first conveyor belt 12 and the carrier 30, so that the speed of the carrier 30 is uniformly increased and accelerated, and the relative motion between the conveyor belt and the carrier 30 is prevented. When the speed of the carrier 30 increases to the same speed as the first conveyor belt 12, the first conveyor belt 12 and the carrier 30 are at the same speed, and there is no relative motion or a tendency for relative motion. During the acceleration process of the carrier 30, the sliding friction force between the first conveyor belt 12 and the carrier 30 will wear the first conveyor belt 12, and easily cause the sliding between the carrier 30 and the first conveyor belt, so that the carrier 30 is accelerated slowly. The pre-pressing mechanism 13 presses the edge of the carrier 30 against the first conveyor belt 12, when the first conveyor belt 12 is started, the sliding friction force between the edge of the carrier 30 and the first conveyor belt 12 can be increased, the carrier 30 can obtain a larger acceleration due to the large sliding friction force, the time for the carrier 30 and the first conveyor belt 12 to reach a common speed is shortened, and the transportation efficiency of the first conveyor belt 12 for transporting the carrier 30 is improved.

When the prepressing mechanism 13 is provided with a magnetic component, the prepressing mechanism 13 may be disposed below or above the hanging plate 11 at intervals, or may be disposed below the hanging plate 11 in a head-to-tail manner. When the prepressing mechanism 13 is the roller prepressing mechanism 13, the roller prepressing mechanisms 13 are arranged at the upper end of the hanging plate 11 at intervals. In addition, the positions of the roller prepressing mechanisms 13 on the two hanging plates 11 correspond to each other. Namely, a roller wheel prepressing mechanism 13 is arranged on one hanging plate 11, and a roller wheel prepressing mechanism 13 is also arranged at the corresponding position of the other hanging plate 11. Two corresponding roller pre-pressing mechanisms 13 on the two hanging plates 11 respectively press two edge portions of the carrier 30 to respective first conveyor belts 12, so that two ends of the carrier 30 are stressed in a balanced manner, and products in the carrier 30 are prevented from being damaged or tilted due to damage or tilting of the carrier 30.

As shown in fig. 3, fig. 3 is a schematic perspective view of the carrier reflow apparatus 20. The carrier reflow apparatus 20 includes a fixing frame 21 and a second conveyor belt 22. The fixing frame 21 is used for fixing the carrier transportation device 10 and the carrier backflow device 20, the carrier transportation device 10 is fixed above the fixing frame 21, and the carrier backflow device 20 is fixed below the fixing frame 21. The second conveyor belt 22 is fixedly arranged on the fixed frame 21 and is positioned below the carrier transportation device 10, and the conveying direction of the second conveyor belt 22 is opposite to the conveying direction of the first conveyor belt 12, so that the carrier 30 can be reflowed, and the carrier 30 can be recycled.

The carrier reflow apparatus 20 also includes a second driving device 23, and the second driving device 23 is used for driving the second belt 22 to rotate. The second driving device 23 drives the second conveyor belt 22 in the same operation principle as the first driving device 14 drives the first conveyor belt 12. The second driving device 23 may be disposed below the second conveyor belt 22. The second driving device 23 includes a second motor 231, a second transmission shaft 232, a second driving pulley 233, and a second driven pulley 234.

Furthermore, the second conveyor belt 22 may be implemented as a belt, or may be an entire belt. In the embodiment, the second conveyor 22 is the same as the first conveyor 12, and has two belts respectively located at two sides of the pre-pressing assembly line and arranged in parallel to each other, so that the middle of the carrier reflow apparatus 20 is also in a suspended state. The same second motor 231 drives the same second transmission shaft 232 to drive the second driving wheel 233 and the second driven wheel 234 corresponding to the two belts to rotate, so that the two belts of the second transmission belt 22 can rotate synchronously. The second conveyor belt 22 may also be implemented by rollers, chains, rollers, or conveyor rollers, etc.

In some embodiments, as shown in fig. 4 and 5, there are a front view and a top view of the plurality of roller pre-pressing mechanisms 13 on the hanging plate 11, respectively. Wherein, each gyro wheel pre-compaction mechanism 13 includes: the riser 131, the pressing portion 132, and the prepressing portion 133 are moved. As shown in fig. 4, the movable riser 131 is located outside the hanging plate 11 and moves up and down with respect to the hanging plate 11. As shown in fig. 5, the pressing portion 132 is connected to the moving riser 131 and is used to abut against an edge portion of the carrier 30. In the present embodiment, the pressing portion 132 is horizontally fixed above the moving riser 131 and is disposed higher than the hanging plate 11. The prepressing sections 133 are connected to the movable riser 131, and the prepressing sections 133 provide downward prepressing force to the pressing sections 132 through the movable riser 131. Specifically, the movable vertical plate 131 is a plate-shaped structure, and the movable vertical plate 131 is located on the outer side of the hanging plate 11 and can move up and down relative to the hanging plate 11, so as to drive the pressing part 132 located at the upper end of the movable vertical plate 131 to move up and down.

The pressing portion 132 is also disposed in a plate-like structure. The pressing part 132 is perpendicular to the movable riser 131 and extends toward the first conveyor belt 12, and the pressing part 132 is disposed higher than the upper ends of the hanging plates 11, so that the pressing part 132 has a height difference from the first conveyor belt 12 between the hanging plates 11. The first conveyor belt 12 is used for placing and transporting the carrier 30, the edge portion of the carrier 30 is located between the pressing portion 132 and the first conveyor belt 12, and the thickness of the carrier 30 is greater than the height difference between the pressing portion 132 and the first conveyor belt 12, so that the lower surface of the edge portion of the carrier 30 can be abutted to the upper surface of the first conveyor belt 12, and the upper surface of the edge portion of the carrier 30 can be abutted to the lower surface of the pressing portion 132.

The prepressing section 133 is connected to the movable vertical plate 131, and when the movable vertical plate 131 is outside the hanging plate 11, the prepressing section 133 balances the gravity of the movable vertical plate 131 and the supporting force of the prepressing section 133. The prepressing portion 133 can provide upward supporting force for the moving riser 131, so that the moving riser 131 is located on the outer side of the hanging plate 11, when the moving riser 131 moves upward, the prepressing portion 133 can also provide downward tensioning force for the moving riser 131, and then provide downward tensioning force for the pressing portion 132 located at the upper end of the moving riser 131, because the lower surface of the pressing portion 132 is abutted to the upper surface of the edge portion of the carrier 30, the prepressing portion 133 acts on the pressing portion 132 through the moving riser 131, and when the pressing portion 132 is abutted to the edge portion of the carrier 30, the prepressing portion is converted into downward prepressing force for the edge portion of the carrier 30.

In some embodiments, the pre-pressing portion 133 includes a first guide mechanism 1331 and a first elastic member 1332. Specifically, the first guide mechanism 1331 is vertically fixed to the hanging plate 11 and engaged with the moving riser 131. The movable vertical plate 131 is matched with the first guide mechanism 1331, the movable vertical plate 131 moves up and down along the first guide mechanism 1331 relative to the hanging plate 11, the first guide mechanism 1331 provides the displacement amount when the hanging plate 11 moves up and down for the movable vertical plate 131, meanwhile, the first guide mechanism 1331 can also play a role in guiding, the movable vertical plate 131 is ensured to be in a vertical state in the up-and-down movement process, and therefore the pressing part 132 positioned at the upper end of the movable vertical plate 131 is further ensured to be in a horizontal state, and the pressing part 132 and the edge part of the carrier 30 on the first conveyor belt 12 can be completely attached without separation. In addition, the first guide mechanism 1331 and the moving riser 131 may be implemented by a slide rail and a slider, and the slider provided to the moving riser 131 slides along the slide rail. The first guide mechanism 1331 and the movable vertical plate 131 can also be realized by a guide rod and a shaft sleeve, and the shaft sleeve of the movable vertical plate 131 is sleeved outside the guide rod.

Further, the upper end of the first elastic piece 1332 is connected with the movable vertical plate 131, and the lower end of the first elastic piece 1332 is connected with the hanging plate 11. The first elastic member 1332 is used to connect the hanging plate 11 and the moving riser 131. The lower end of the first elastic piece 1332 is connected with the hanging plate 11, and may be fixedly connected or hooked. The upper end of the first elastic piece 1332 is connected with the movable vertical plate 131, and can be fixedly connected or detachably connected by hooking. As can be seen from the above, the pre-pressing portion 133 can provide an upward supporting force for the movable vertical plate 131, so that the movable vertical plate 131 is located outside the hanging plate 11, and when the movable vertical plate 131 moves upward, the pre-pressing portion 133 can also provide a downward tensioning force for the movable vertical plate 131. When the first elastic piece 1332 connects the hanging plate 11 and the moving vertical plate 131, the elastic force of the first elastic piece 1332 and the gravity of the moving vertical plate 131 are offset, so that the first elastic piece 1332 is in a balanced state. When the first elastic piece 1332 is in a balanced state, the first elastic piece 1332 supports the moving riser 131 such that the distance separating the pressing portion 132 and the first conveyor belt 12 is smaller than the thickness of the edge portion of the carrier 30.

The first guiding mechanism 1331 of the prepressing portion 133 is matched with the first elastic piece 1332, so that the movable vertical plate 131 vertically moves up and down in the outer side of the hanging plate 11, and the first guiding mechanism 1331 is also ensured to be in a vertical state in the process of moving up and down, thereby further ensuring that the pressing portion 132 positioned at the upper end of the movable vertical plate 131 is in a horizontal state, and further ensuring that the pressing portion 132 and the edge portion of the carrier 30 on the first conveyor belt 12 can be completely attached without separation.

In some embodiments, the pre-pressing portion 133 further includes a spacing pin 1333. The upper end of the limit pin 1333 abuts against the lower part of the movable vertical plate 131 and is used for limiting the lowest position of the downward movement of the movable vertical plate 131; the spacing distance between the pressing part 132 and the first conveyor belt 12 is adjusted by adjusting the position of the limiting pin 1333 on the hanging plate 11 up and down.

Specifically, when the elastic force of the first elastic piece 1332 is small, the first elastic piece 1332 cannot support the moving riser 131 compared with the gravity of the moving riser 131, and the moving riser 131 compresses the first elastic piece 1332 under the action of gravity, so that the distance between the pressing portion 132 on the moving riser 131 and the first conveyor belt 12 is too small. The stopper pin 1333 is provided, and the upper end of the stopper pin 1333 abuts against the lower side of the movable vertical plate 131, so that when the stopper pin 1333 is fixed to the hanging plate 11, the movable vertical plate 131 can be restricted from moving downwards, and the distance between the upper end pressing part 132 of the movable vertical plate 131 and the first conveyor belt 12 can be fixed. The phenomenon that the edge of the carrier 30 on the first conveyor belt 12 cannot pass through due to the small spacing distance between the pressing part 132 and the first conveyor belt 12, which hinders the carrier 30 from being transported by the first conveyor belt 12, is avoided.

In one embodiment, the limiting pin 1333 may be a vertically disposed bolt, a nut engaged with the bolt is disposed on the outer side of the hanging plate 11, the nut is fixed on the outer side of the hanging plate 11, the upper end of the limiting pin 1333 passes through the nut and abuts against the movable vertical plate 131 to limit the downward movement of the movable vertical plate 131, and the bolt is vertically moved up and down by rotating the bolt, so as to adjust the lowest position of the movable vertical plate 131 moving downward. Thus, the height difference between the pressing portion 132 and the first conveyor belt 12 is adjusted by rotating the bolt, thereby adjusting the pre-pressure of the pressing portion 132 against the edge portion of the carrier 30 positioned on the first conveyor belt 12.

In another embodiment, the retaining pin 1333 may be a horizontally disposed pin or bolt. Specifically, the hanging plate 11 is provided with a plurality of limiting holes for accommodating the limiting pins 1333, and the limiting holes are arranged in the vertical direction. The stopper pin 1333 is inserted into the stopper hole by changing its position, thereby defining the lowermost position at which the moving riser 131 moves downward. The height difference between the pressing portion 132 and the first conveyor belt 12 is further adjusted, thereby adjusting the pre-pressure of the pressing portion 132 against the edge portion of the carrier 30 positioned on the first conveyor belt 12.

The prepressing part 133 is provided with a limit pin 1333, and firstly, the upper end of the limit pin 1333 is abutted to the movable vertical plate 131 to support the movable vertical plate 131, so that the stability is improved. Second, the limiting pin 1333 can limit the lowest position of the moving riser 131 moving downwards, so as to avoid that the distance between the pressing portion 132 and the first conveyor belt 12 is too small and the conveying efficiency of the carrier 30 is affected due to the downward movement of the moving riser 131 under the action of gravity. Thirdly, through adjusting the position of spacer pin 1333 in the vertical direction of link plate 11, can adjust the spacing distance between portion 132 and the first conveyer belt 12 that compresses tightly to and adjust the precompression of portion 132 to the edge portion of carrier 30, thereby can satisfy the different carriers 30 that have different edge portion thicknesses, the suitability is wider, and the commonality is stronger.

In some embodiments, the first guide mechanism 1331 has two, and the two first guide mechanisms 1331 are arranged in parallel in the vertical direction; the first elastic members 1332 are two, and the two first elastic members 1332 are located between the first guide mechanisms 1331 and arranged in parallel in the vertical direction; the spacing pin 1333 has one, and is located between the two first elastic members 1332.

The limiting pin 1333 is a vertically arranged bolt, and is matched with a nut fixed on the hanging plate 11, so that the lowest position of the moving vertical plate 131 moving downwards is adjusted by rotating the bolt.

In some embodiments, the compression portion 132 includes a cage 1321. The fixed end of the holder 1321 is fixed to the upper end of the movable riser 131, and the free end of the holder 1321 is suspended above the first conveyor belt 12.

In the present embodiment, the retainer 1321 has a plate-like structure, and the retainer 1321 is disposed horizontally and perpendicular to the movable riser 131. The fixed end of the roller retainer 1321 is fixed on the movable vertical plate 131 and can move up and down along with the movable vertical plate 131 in the vertical direction.

When the first conveyor belt 12 transports the carrier 30, the carrier 30 moves along with the first conveyor belt 12, and the prepressing mechanism 13 is fixed relative to the hanging plate 11, so that when the pressing portion 132 of the prepressing mechanism 13 presses the edge portion of the carrier 30, the pressing portion 132 moves relative to the edge portion of the carrier 30. In one embodiment, a soft material such as sponge may be disposed on the lower surface of the retainer 1321 to prevent the edge of the carrier 30 and the retainer 1321 from being worn by sliding friction therebetween when the edge of the carrier 30 contacts the retainer 1321. In another embodiment, the bearing rollers 1322 are disposed on the holder 1321, the bearing rollers 1322 are embedded in the holder 1321, and the rolling direction of the bearing rollers 1322 is the same as the conveying direction of the carrier 30. Two bearings may be provided, respectively at the front and rear ends of the holder 1321 in the conveying direction. The plurality of bearing rollers 1322 may be provided, and the plurality of bearing rollers 1322 are embedded in the holder 1321 at intervals for abutting against the edge portion of the carrier 30. When the edge portion of the carrier 30 on the first conveyor belt 12 and the pressing portion 132 move relatively, the bearing rollers 1322 are provided, so that the relative movement between the edge portion of the carrier 30 and the pressing portion 132 is changed from sliding to rolling, the rolling friction force is smaller than the sliding friction force, and when the holder 1321 presses the edge portion of the carrier 30, the abrasion and damage of the edge portion of the carrier 30, the holder 1321 of the pressing portion 132, and the bearing rollers 1322 due to the friction force therebetween can be reduced.

In addition, the holder 1321 is provided with a bevel edge at both ends in the conveying direction of the carrier 30, and the bevel edge is introduced in order to prevent the carrier 30, which is running at a high speed, from hitting the edge of the holder 1321 when the edge portion of the carrier 30 enters the space between the holder 1321 and the first conveyor belt 12, and thus to prevent the holder 1321 and the carrier 30 from being damaged by the hitting of the both.

In another embodiment, the pre-press mechanism 13 moves with the carrier 30 so that the relative speed of the two is zero, while the pre-press mechanism 13 moves with the carrier 30 relative to the carrier transporter 10. Specifically, the hanging plate 11 is provided with a third guiding mechanism, which may be located outside the hanging plate 11, and the extending direction of the third guiding mechanism is the same as the traveling direction of the carrier 30. A moving member is provided to cooperate with the third guide mechanism, and a prepressing mechanism 13 is provided on the moving member.

When the pre-pressing mechanism 13 presses the edge portion of the carrier 30 against the first conveyor belt 12 by pressing, the pre-pressing mechanism 13 may include a moving riser 131, a pressing portion 132, and a pre-pressing portion 133. The pre-pressing part 133 is provided to the moving member, and thus the first guide mechanism 1331, the first elastic member 1332 and the stopper pin 1333 of the pre-pressing part 133 are provided to the moving member. The pressing portion 132 includes a holder 1321, and the bearing roller 1322 may not be provided on the holder 1321. Specifically, when the edge portion of the carrier 30 is engaged with the preliminary press mechanism 13, the preliminary press portion 133 of the preliminary press mechanism 13 provides preliminary press force to the pressing portion 132 by moving the riser 131, and the preliminary press force causes the pressing portion 132 to abut against the edge portion of the carrier 30 and presses the edge portion of the carrier 30 against the first conveyor belt 12. The upper surface and the portion 132 butt that compresses tightly of carrier 30, the lower surface and the contact of first conveyer belt 12 of carrier 30, first conveyer belt 12 drives carrier 30 operation, and the edge portion of carrier 30 drives the operation of prepressing mechanism 13 through the butt with portion 132 that compresses tightly to drive moving part and move on being located the third guiding mechanism on the link plate. At this time, the carrier 30 and the pre-pressing mechanism 13 are simultaneously moved, and the relative speed of the two is zero.

When the pre-pressing mechanism 13 presses the edge portion of the carrier 30 to the first conveyor belt 12 by suction, the pre-pressing mechanism 13 may include a pressing portion 132, and the pressing portion 132 is connected to the moving member so as to be movable relative to the hanging plate 11 at the third guide mechanism. The pressing portion 132 is located below the first conveyor belt 12, a magnetic component is disposed at the pressing portion 132, and an edge portion of the carrier 30 also includes a magnetic material. The first conveyor belt 12 drives the carrier 30 to operate, and since the magnetic component at the pressing portion 132 is adsorbed to the edge portion of the carrier 30, the edge portion of the carrier 30 can drive the pressing portion 132 to move, and since the pressing portion is connected with the moving component, the moving component can slide in cooperation with the third guide mechanism. Finally, the pre-pressing mechanism 13 can move together with the carrier 30 through the moving part and the third guiding mechanism, so that the relative speed between the two is zero.

In some embodiments, as further shown in fig. 2 and 3, the vehicle transportation device 10 further includes a plurality of stoppers 15. The limiting block 15 is positioned between the two roller pre-pressing mechanisms 13. The first end of the limiting block 15 is fixed on the hanging plate 11, and the second end of the limiting block 15 is suspended above the first conveyor belt 12 and used for limiting the highest position of the moving vertical plate 131 moving upwards.

The up end at link plate 11 is fixed to stopper 15, the first end of stopper 15 is for being close to the one end in the link plate 11 outside, the second end of stopper 15 is for being close to the inboard one end of link plate 11, the first end of stopper 15 is fixed in link plate 11, the second end of stopper 15 is unsettled with the top of first conveyer belt 12, wherein, the lower surface of stopper 15 second end and the interval distance between first conveyer belt 12 are greater than the interval distance between the portion 132 that compresses tightly of gyro wheel prepressing mechanism 13 and the first conveyer belt 12, thereby be used for injecing the maximum distance that removes riser 131 rebound. The objective is that, firstly, after the carrier 30 of the pre-pressing assembly line further needs the jacking mechanism to jack up the carrier 30, the carrier 30 is separated from the first conveyor belt 12, so that the product on the carrier 30 can be operated without stopping the first conveyor belt 12, and in order to avoid that the jacking height exceeds the deformation range or the load range of the first elastic piece 1332 after the jacking mechanism jacks up the carrier 30, the permanent deformation of the first elastic piece 1332 is caused, so that the first elastic piece 1332 loses elasticity and cannot rebound, and the effect of generating a pre-pressing force on the edge portion of the carrier 30 is lost. Secondly, when the articles other than the carrier 30 fall onto the first conveyor belt 12, the stopper 15 can also block the sundries on the first conveyor belt 12 and prevent the sundries from being conveyed further. Thirdly, the roller pre-pressing mechanisms 13 are arranged on the hanging plate 11 at intervals, and when the edge part of the carrier 30 moves between two adjacent roller pre-pressing mechanisms 13, the limiting block 15 is arranged to prevent the edge part of the carrier 30 from tilting due to the pressing of the roller pre-pressing mechanisms 13.

In some embodiments, as further shown in fig. 1, the carrier transportation device 10 corresponds to a plurality of stations. The carrier transportation device 10 corresponds to a plurality of stations, each station corresponds to a certain process, that is, each station occupies a certain position on the assembly line, and each station can perform a plurality of processes on the product carried in the carrier 30. When the product in the carrier 30 needs to be operated, the running carrier 30 needs to be stopped. The carrier 30 may be stopped by closing the first conveyor 12, and after the operations of the plurality of processes at the station are completed, the first conveyor 12 is opened to convey the carrier 30 to the next station for operation. However, when the first belt 12 is repeatedly opened and closed, the current rush at the time of opening is more harmful to the first driving device 14 driving the first belt 12. In addition, when the first conveyor belt 12 is repeatedly opened and closed, the speed of the carrier 30 needs to be repeatedly accelerated and decelerated at the first conveyor belt 12, which not only increases the number of times and time for the carrier 30 and the first conveyor belt 12 to be worn, but also reduces the conveying efficiency of the first conveyor belt 12 for conveying the carrier 30.

Therefore, in one embodiment, as shown in fig. 2, each station is provided with a blocking mechanism 16, a jacking mechanism 17 and an anti-rebounding mechanism 18. The blocking mechanism 16 is located in the traveling direction of the carrier 30 along the conveying direction of the carrier 30, and when the blocking member 161 of the blocking mechanism 16 extends out of the traveling path of the carrier 30, it is used for blocking the carrier 30 from running on the first conveyor belt 12. The jacking mechanism 17 is located behind the blocking mechanism 16 along the conveying direction of the carrier 30, and a jacking piece 171 of the jacking mechanism 17 is used for jacking the carrier 30 and separating from the first conveyor belt 12. The anti-rebound mechanism 18 is located behind the carrier 30 in the conveying direction of the carrier 30, and is used for blocking the carrier 30 from rebounding on the first conveyor belt 12.

The set of blocking mechanism 16, the set of jacking mechanism 17 and the set of anti-rebound mechanism 18 form a station, the carrier 30 moves forward on the first conveyor belt 12 of the carrier conveying device 10, the carrier 30 can be blocked at the corresponding station through the blocking mechanism 16, the anti-rebound mechanism 18 blocks rebound of the carrier 30 to complete accurate positioning of the carrier 30 at the station, the carrier 30 after being blocked is jacked by the jacking mechanism 17, processing can be carried out at the corresponding station, and after the processing is completed, the blocking mechanism 16 and the jacking mechanism 17 are closed to enable the carrier 30 to flow to the next station. In the present embodiment, the set of blocking mechanisms 16 includes two blocking mechanisms 16, which are respectively fixed on the inner side of the hanging plate 11 and are symmetrical with respect to the carrier 30. Similarly, the group of jacking mechanisms 17 and the group of anti-rebound mechanisms 18 respectively comprise two jacking mechanisms and two anti-rebound mechanisms, and are respectively fixed on the inner sides of the hanging plates 11.

In one embodiment, the blocking member of blocking mechanism 16 may rise upward in a vertical direction or may extend inward of the belt in a horizontal direction, or may extend out of the path of travel of carrier 30 in an inclined direction. When the blocking member of the blocking mechanism 16 extends in the horizontal direction for blocking the carrier 30, the blocking member of the blocking mechanism 16 is horizontally disposed on the inner side of the hanging plate 11 and above the first conveyor belt 12. By means of a horizontally protruding stop for stopping the carriers 30 running at high speed on the first conveyor belt 12. In the present embodiment, the stopper 161 of the stopper mechanism 16 may be raised upward in the vertical direction. Specifically, as shown in fig. 6, fig. 6 is a schematic structural view of the blocking mechanism 16. The blocking mechanism 16 is disposed in front of the carrier 30 in the transport direction of the carrier 30, so that the carrier 30 can be blocked at the corresponding station. Specifically, the blocking mechanism 16 includes a first fixing block 162 and a first driving member 163, in addition to the blocking member 161. As shown in fig. 1 and 2, the first fixing block is fixed to the inner side of the hanging plate 11. The upper end surface of the first fixing block 162 is lower than the plane of the first conveyor belt 12, and does not affect the operation of the carrier 30 on the first conveyor belt 12 when the blocking mechanism 16 does not work. The blocking member 161 can move up and down relative to the first fixed block 162, the first driving member 163 is also fixed to the first fixed block 162, and the first driving member 163 drives the blocking member 161 to extend or retract on the traveling path of the carrier 30. In the present embodiment, the first driver 163 drives the stopper 161 to move up and down in the vertical direction. When the first driving member 163 drives the blocking member 161 to ascend, the upper end of the blocking member 161 is higher than the plane of the first conveyor belt 12, and when the blocking member 161 descends, the upper end of the blocking member 161 may descend to be lower than the upper end surface of the first fixing block 162. When the jacking mechanism 17 is started, the blocking member 161 is lifted to block the carrier 30 in operation of the first conveyor belt 12, so that the carrier 30 is stopped at the corresponding station.

The first driver 163 may be implemented by a motor, a cylinder, or the like. The first driver 163 drives the blocking member 161 to be movable up and down in the vertical direction, and the blocking member 161 may be implemented by a rack, a jack-up rod, or the like. In this embodiment, the first driving member 163 is an air cylinder, and the blocking member 161 is a lift pin.

In addition, a through hole is formed at the upper end of the first fixed block 162, and the first driver 163 drives the upper end of the stopper 161 to pass through the through hole of the first fixed block 162. The through hole is provided to prevent the stopper 161 from being bent or damaged due to collision of the stopper 161 by the carrier 30 accidentally separated from the first conveyor belt 12, because the stopper 161 is located below the upper end surface of the first fixed block 162 in the non-activated state of the lift mechanism 17. When the jacking mechanism 17 is in the starting state, the blocking member 161 rises above the first conveyor belt 12, and when the carrier 30 running on the first conveyor belt 12 is blocked, the upper end of the first fixing block 162 can provide extra supporting force for the blocking member 161, so that the blocking member 161 is prevented from being collided and bent due to large inertia caused by too high speed of the carrier 30, and the service life of the blocking member 161 is prolonged.

The blocking mechanism 16 can stop the carrier 30 without closing the first conveyor belt 12, thereby avoiding repeated restarting and closing of the first conveyor belt 12, reducing damage to the first driving device 14 driving the first conveyor belt 12, reducing the number and time of abrasion between the carrier 30 and the first conveyor belt 12, and improving the conveying efficiency of the first conveyor belt 12 for conveying the carrier 30.

In one embodiment, the carrier transportation device 10 has a plurality of stations, when the carrier 30 needs to stop and start the blocking mechanism 16 at the corresponding station, the operator can control the blocking mechanism 16 through a controller of the control center, the controller controls the start and stop of the blocking mechanism 16 through preset stop time and position, etc., and stops the carrier 30 at the corresponding station, and operates the corresponding process on the product in the carrier 30.

In another embodiment, the blocking mechanism 16 further includes a sensor 164. The sensor 164 is fixed to the first fixing block 162, and is used for sensing the carrier 30 and controlling the first driving element 163 to drive the blocking element 161 to extend or retract on the traveling path of the carrier 30. Specifically, in the present embodiment, the sensor 164 is used for sensing the carrier 30 and controlling the first driving element 163 to drive the blocking element 161 to move up and down in the vertical direction.

Specifically, the sensor 164 is fixed near the first fixing block 162, and the distance between the sensor 164 and the carrier 30 is smaller than the distance between the stopper 161 and the carrier 30 when the sensor 164 is located behind the stopper 161 in the conveying direction of the carrier 30, that is, the carrier 30 is not stopped. When the carrier 30 is operated, the sensor 164 senses the carrier 30 first, the sensor 164 transmits a signal to the control center in a wired or wireless manner, and the controller of the control center sends a command to control the first driving member 163 to drive the blocking member 161 to lift up, so as to block the operation of the carrier 30 on the first conveyor belt 12.

In addition, a second sensor 164 may be further disposed on the first fixed block 162, and the second sensor 164 is located in front of the blocking member 161 in the conveying direction of the carrier 30. The second sensor 164 is provided for the purpose that firstly, when the products in the carrier 30 complete a plurality of operation processes at the corresponding station, the blocking member 161 descends to allow the carrier 30 to be conveyed to the next station to complete the corresponding process, and when the carrier 30 runs to the next process, the carrier 30 does not completely depart from the sensing range of the first sensor 164, so that when the carrier 30 crosses the blocking member 161, the second sensor 164 can be triggered, the second sensor 164 senses the carrier 30 and sends a signal to the controller of the control center to indicate that the carrier 30 is running to the next station, and the controller controls the first driving member 163 to avoid the blocking member 161 from rising again, thereby protecting the carrier 30 and the products in the carrier 30, effectively improving the transportation efficiency of the carrier 30, and using a highly automated wire.

It should also be noted that the blocking mechanisms 16 may also be provided at the head and tail ends of the carrier reflow apparatus 20. The blocking mechanism 16 in the carrier reflow device 20, the blocking mechanism 16 at the end of the carrier reflow device 20 can block the carrier 30 in the second conveyor belt 22 to avoid collision with the carrier 30 in the carrier transportation device 10. The stop mechanism 16 in the vehicle reflow apparatus 20 may also control the raising and lowering of the stop 161 by the controller of the control center.

The blocking mechanism 16 may enable the carrier 30 to stop at different stations, when the carrier 30 stops, the first conveyor belt 12 moves, the carrier 30 and the first conveyor belt 12 move relatively, and the lower surface of the carrier 30 and the upper surface of the first conveyor belt 12 have sliding friction, so as to avoid abrasion of the carrier 30 or the first conveyor belt 12 due to the sliding friction. In some embodiments, as shown in fig. 2, the vehicle transportation device 10 is provided with a jacking mechanism 17 at each station. Fig. 7 is a schematic structural diagram of the jacking mechanism 17. The lifting mechanism 17 includes a second fixing block 172, a second driving member 173 and a second guiding mechanism 175 in addition to the lifting member 171. The second fixing block 172 is fixed to the inner side of the hanging plate 11; the second driving member 173 is fixed to the second fixing block 172, and the second driving member 173 is used for driving the lifting member 171 to move up and down in the vertical direction.

Specifically, when the jacking mechanism 17 is not activated, the jacking member 171 of the jacking mechanism 17 is positioned below the first conveyor belt 12, so that the operation of the carrier 30 on the conveyor belt is not affected. When the jacking mechanism 17 is activated, the jacking member 171 of the jacking mechanism 17 can be lifted above the first conveyor belt 12, so as to jack up the carrier 30 on the first conveyor belt 12 and drop off the first conveyor belt 12. The blocking mechanism 16 is prevented from blocking the sliding friction between the lower surface of the carrier 30 and the first conveyor belt 12 after the carrier 30 stops. In addition, when the sensor 164 of the blocking mechanism 16 sends a signal to the controller of the control center, the control center may also control the jacking member 171 of the jacking mechanism 17 to lift upwards after the blocking member 161 of the blocking mechanism 16 blocks the operation of the carrier 30, so as to lift and separate the carrier 30 from the first conveyor belt 12. The second driving member 173 may be implemented by a motor, a cylinder, etc. The second driving member 173 drives the lifting member 171 to move up and down in the vertical direction, and the lifting member 171 may be implemented by a rack, a lifting plate, or the like. In this embodiment, the second driving member 173 is a cylinder, and the lifting member 171 is a lifting plate.

In some embodiments, the jacking mechanism 17 further comprises a second guiding mechanism 175, vertically fixed to the hanging plate 11; and cooperates with the lifter 171 to define the motion trajectory of the lifter 171. Jacking piece 171 and the cooperation of second guiding mechanism 175, jacking piece 171 reciprocates along the relative link plate 11 of second guiding mechanism 175, and second guiding mechanism 175 plays the guide effect to jacking piece 171, ensures that jacking piece 171 is vertical state at the in-process of up-and-down motion, further ensures that jacking piece 171 is the horizontality when jacking carrier 30, avoids carrier 30 crooked and leads to the product in the carrier 30 to drop. In addition, the second guide mechanism 175 and the lifting member 171 may be implemented by a slide rail and a slider, and the slider provided to the lifting member 171 slides along the slide rail. The second guiding mechanism 175 and the lifting member 171 can also be realized by a guiding rod and a shaft sleeve, and the shaft sleeve of the lifting member 171 is sleeved outside the guiding rod.

In some embodiments, the lifting member 171 is provided with a positioning pin 174 disposed at an upper end of the lifting member 171; when the carrier 30 is lifted up, the positioning pin 174 is inserted into the positioning hole of the carrier 30 for preventing the carrier 30 from falling off. Specifically, the upper end of the jacking member 171 is provided with a positioning pin 174, the positioning pin 174 protrudes out of the jacking member 171, and the position of the positioning pin 174 corresponds to the positioning hole at the lower end of the carrier 30, so that the positioning pin can be inserted into the positioning hole of the carrier 30 when the jacking mechanism 17 jacks up the carrier 30, the accurate position of the carrier 30 can be determined, and the carrier 30 is ensured to slide off the jacking member 171 due to shaking, collision and other reasons in the jacking process, so that products in the carrier 30 are damaged.

In some embodiments, as depicted in FIG. 8, FIG. 8 is a schematic view of the kickback prevention mechanism 18. The kickback prevention mechanism 18 includes: a third fixing block 181, an anti-rebound block 182 and an elastic member 183. The third fixing block 181 is fixed on the inner side of the hanging plate 11, and is used for fixing the rebound prevention mechanism 18 on the hanging plate 11. A groove extending along the conveying direction is formed above the third fixing block 181; the groove is arranged in a square structure. The anti-bounce block 182 is positioned in the groove, and the anti-bounce block 182 comprises a pivoting end positioned at the rear part in the conveying direction and a bounce end positioned at the front part in the conveying direction; the pivoting end is pivoted with the groove, the rebounding end is connected with the groove through an elastic piece 183, and the elastic piece 183 is used for providing upward elastic force for the rebounding prevention block 182.

In the implementation process, the bounce-back prevention block 182 is under the elastic force of the elastic member 183, and the bounce-back end of the bounce-back prevention block 182 is higher than the upper end surface of the third fixing block 181 and higher than the plane of the first conveyor belt 12. Since the pivot end of the anti-rebound block 182 is located at the rear of the conveying direction and the rebound end is located at the front end of the conveying direction, when the lower surface of the carrier 30 contacts with the rebound end of the anti-rebound block 182 under the normal operation condition of the carrier 30, the carrier 30 presses the rebound end of the anti-rebound block 182 under the action of gravity and the pre-pressing mechanism 13, the elastic member 183 connected with the rebound end is compressed, and the rebound end moves into the groove. When the carrier 30 passes over the rebound end, the rebound end of the rebound prevention block 182 rebounds under the elastic force of the elastic member 183 and protrudes out of the plane of the first conveyor belt 12 again. Therefore, when the blocking member 161 of the blocking mechanism 16 blocks the carrier 30 running at a high speed on the first conveyor belt 12, the carrier 30 rebounds due to inertia, and the blocking mechanism 16 is arranged to prevent the carrier 30 from rebounding and swinging backwards, so as to ensure that the product in the carrier 30 is not damaged, and the combination of the blocking mechanism 16 and the bounce-preventing mechanism 18 enables the carrier 30 to be fixed at a corresponding operation position when the carrier stops, so that the position of the carrier is accurate, and the product on the carrier 30 can be conveniently processed without deviation. The elastic member 183 may be implemented by a structure having elastic deformation, such as a spring, or rubber. In this embodiment, the elastic member 183 is a spring.

In addition, as shown in fig. 2, at least one pair of roller pre-pressing mechanisms 13 is correspondingly arranged at each station, and at least one pair of roller pre-pressing mechanisms 13 is arranged between the two stations. The purpose is to avoid the falling off of the carrier 30 at the non-station position; secondly, when the carrier 30 contacts the anti-bounce block 182 of the anti-bounce mechanism 18, the roller pre-pressing mechanism 13 prevents the anti-bounce block 182 from ejecting the carrier 30 out of the first conveyor belt 12.

The operation of the prepressing line will be described in detail with specific embodiments. As shown in fig. 1, the pre-pressing line has two stations, one carrier 30 being provided at each station.

The carrier 30 is placed on the first conveyor belt 12 such that the edge portion of the carrier 30 is positioned between the holder 1321 and the first conveyor belt 12.

The pre-compaction line is started and the first conveyor 12 and the second conveyor 22 are operated.

The carrier 30 is driven by the first conveyor belt 12 to operate, when the carrier 30 is to operate to the first station, the front end of the carrier 30 touches the anti-bounce block 182 of the anti-bounce mechanism 18, and presses the anti-bounce block 182 into the groove of the third fixed block 181, the carrier 30 continues to operate under the drive of the first conveyor belt 12, when the front end of the carrier 30 touches the sensor 164 of the blocking mechanism 16, the sensor 164 sends a signal to the controller of the control center, and the controller controls the first driving part 163 to drive the blocking part 161 to lift upwards, and blocks the operation of the carrier 30 on the first conveyor belt 12.

The controller then controls the second driving member 173 of the jacking mechanism 17 to drive the jacking member 171 to move upwards, and the positioning pin 174 of the jacking mechanism 17 is inserted into the positioning hole of the carrier 30, so as to stably lift and separate the carrier 30 from the first conveyor belt 12.
