In a first aspect, the present application provides a coding apparatus comprising: the feeding mechanism comprises at least two feeding clamps and at least two linear guide rails which extend along a first direction and are arranged in parallel along a second direction, and each feeding clamp can do linear reciprocating movement between a first position and a second position along the respective linear guide rail, wherein the first direction is perpendicular to the second direction; the coding mechanism is positioned between the first position and the second position along the first direction and is used for coding the workpiece to be coded on the feeding clamp which moves to the coding area of the coding mechanism, and at least two feeding clamps carrying the workpiece to be coded can alternately pass through the coding area of the coding mechanism; the code scanning mechanism is positioned at the downstream side of the code etching mechanism along the first direction and is used for scanning the code of the coded workpiece on the feeding clamp which moves to the code scanning area of the code scanning mechanism; the material taking mechanism is used for picking up scanned workpieces on the feeding clamp; the coding mechanism and the code scanning mechanism are both positioned on the same side of the feeding mechanism along the second direction.

In the embodiment of the application, each feeding clamp moves along the respective linear guide rail, so that the feeding clamps are mutually independent and can respectively move so as to realize the mutual alternate coding of the workpieces clamped by the feeding clamps, thereby being beneficial to realizing the automatic circulation of a series of actions of feeding, coding, code scanning and material taking and being beneficial to improving the beat of a production line. Because the at least two feeding clamps are arranged and pass through the coding mechanism alternately, at the same moment, at least two workpieces can be respectively subjected to different operations and only one workpiece is coded, and especially at least two workpieces to be coded are subjected to coding alternately, so that the risk of repeated coding on different workpieces can be restrained, and the operation efficiency can be improved. In addition, when one of the feeding clamps is damaged or maintained, the whole operation can be still realized through the other feeding clamps, and the influence of shutdown caused by the damage or maintenance of the feeding clamps on the production takt, the production efficiency and the like can be reduced. Because the material taking mechanism capable of picking up scanned workpieces on the material feeding clamp is arranged, and the material feeding clamp can reciprocate, the material feeding clamp can be emptied by the material taking mechanism so as to place new workpieces to be marked, and automatic circulation operation is realized. The feeding mechanism, the coding mechanism and the code scanning mechanism are arranged between the first position and the second position in a concentrated mode, so that the conveying route is simplified and shortened, and the occupied area of the device is reduced. The code scanning mechanism and the code etching mechanism are arranged on the same side along the second direction, so that the feeding clamp can clamp the workpiece, the surface to be coded on the workpiece faces the code etching mechanism, and when the workpiece moves to the code scanning mechanism after being coded, the surface of the workpiece, on which the code is etched, faces the code scanning mechanism, the workpiece does not need to be turned over, and the structure and the operation steps of the feeding clamp are simplified.

The region where the code-engraving mechanism 11 can perform code-engraving is a code-engraving region, the region where the code-scanning mechanism 12 can perform code-scanning is a code-scanning region, and the code-scanning region, the code-engraving region, the code-scanning region and the second position are sequentially arranged along the first direction X. In the first direction X, the direction of the first position relative to the second position is the upstream side, and the direction of the second position relative to the first position is the downstream side.

The feeding mechanism 10 can clamp or release the workpiece and drive the workpiece to move along the first direction X. Specifically, the feeding mechanism 10 includes a feeding fixture 101, where the feeding fixture 101 can clamp a workpiece and can drive the workpiece to sequentially pass through a coding area and a code scanning area from a first position and finally reach a second position; the workpiece can be driven to return to the first position from the second position through the code scanning area and the code etching area in sequence.

The etching mechanism 11 can etch the workpiece to be etched in the etching area, and the etching mechanism 11 can etch an identification code each time. When the feeding jig 101 moves to the etching area with the work to be etched, the etching mechanism 11 can etch the identification code on the work.

The code scanning mechanisms 12 are capable of scanning and identifying an identification code on a workpiece, each code scanning mechanism 12 being capable of scanning and identifying an identification code one at a time. When the feeding jig 101 moves to the code scanning area with the coded workpiece, the code scanning mechanism 12 can scan and recognize the identification code carved by the code carving mechanism 11.

The reclaimer mechanism 13 is capable of holding or releasing workpieces, and the reclaimer mechanism 13 is capable of picking up scanned workpieces from the feed clamp 101 in the second position, leaving the feed clamp 101 free to hold new workpieces. Further, the scanned workpieces on the take-off mechanism 13 can be transported out, so that the take-off mechanism 13 can continuously clamp new scanned workpieces.

In actual use, the feeding clamp 101 of the feeding mechanism 10 clamps the workpiece to be coded at the first position, drives the workpiece to be coded to move to the coding area, the coding mechanism 11 codes the workpiece, after coding is completed, the feeding clamp 101 drives the coded workpiece to move to the code scanning area, the code scanning mechanism 12 scans the workpiece, and after coding is completed, the feeding clamp 101 drives the scanned workpiece to move to the second position, and the material taking mechanism 13 picks up the scanned workpiece. The empty feeding clamp 101 returns to the first position from the second position to the code scanning area and the code etching area, clamps the workpiece to be coded at the first position, and repeats the steps.

At least two feeding jigs 101 are provided. Each feed jig 101 is moved apart from each other by a distance such that the number of feed jigs 101 entering the coding region for coding at a time is not more than one. Each feeding clamp 101 passes through the one-time coding area in the process of moving from the first position to the second position, and passes through the one-time coding area in the process of returning from the second position to the first position, and when a workpiece on any feeding clamp 101 is coded in the coding area, only the feeding clamp 101 which is being coded can exist in the coding area; when the coding mechanism 11 does not perform coding, a plurality of feeding jigs 101 may exist in the coding region. In order to simplify the working steps and improve the working efficiency, the feeding jigs 101 may be moved in the same movement mode after being spaced apart from each other by a certain distance, so that the feeding jigs 101 alternately pass through the coding mechanism 11.

Alternatively, the plurality of feeding jigs 101 are arranged in the first direction X. The feeding jigs 101 on the upstream side may be started to move first, and after a certain distance, the next feeding jigs 101 on the downstream side of the feeding jigs 101 start to move, each feeding jig 101 is moved at intervals in the first direction X, and when the last feeding jig 101 on the downstream side reaches the second position, all feeding jigs 101 return to the first position. The plurality of feeding jigs 101 may be arranged at a first position at a distance from each other in the first direction X, and then moved downstream together, and all the feeding jigs 101 may be returned to the first position together after reaching the second position.

Also alternatively, a plurality of feeding jigs 101 are arranged in the second direction Y. The feeding clamps 101 respectively start to move from the first position at different time points, the feeding clamp 101 which reaches the second position firstly returns to the first position, clamps a new workpiece firstly, then moves to the second position, and repeats. Wherein the second direction Y is perpendicular to the first direction X.

Therefore, at least two workpieces can be respectively subjected to different operations at the same time, only one workpiece is subjected to the coding, and especially at least two workpieces to be coded are subjected to the coding alternately, so that the risk of repeated coding on different workpieces can be restrained, and the operation efficiency can be improved. In addition, when one of the feeding jigs 101 is damaged or maintained, a complete operation can be still realized through the other feeding jigs 101, which is helpful to reduce the influence of the stop caused by the damage or maintenance of the feeding jigs 101 on the production tact, the production efficiency and the like.

The feed mechanism 10 includes at least two linear rails 102. The plurality of linear guides 102 are arranged in parallel along the second direction Y, and each linear guide 102 extends along the first direction X. Wherein the second direction Y is perpendicular to the first direction X. The end of the linear guide 102 remote from the take-off mechanism 13 is the first position, which is the initial position of the feed clamp 101, and the workpiece is fixed to the feed clamp 101 at the first position. The end of the linear guide 102 near the take-off mechanism 13 is at the second position, and the scanned workpiece is taken out from the feeding clamp 101 at the second position.

Alternatively, the number of linear guides 102 corresponds to the number of feed jigs 101. Each linear guide 102 is provided with a feeding clamp 101, and the feeding clamp 101 can freely move on the linear guide 102. Also optionally, the number of linear guides 102 is less than the number of feed clamps 101. At least two feeding jigs 101 are provided on at least one linear guide 102, each feeding jig 101 being moved apart from each other in the first direction X. The number of linear guides 102 is not particularly limited in the present application.

Alternatively, each feeding jig 101 is different in position in the second direction Y and the third direction Z. At least two feeding jigs 101 can be moved into the coding area or the code scanning area at the same time, and each feeding jig 101 corresponds to a different coding mechanism 11 or code scanning mechanism 12, so that at least two workpieces are coded or scanned simultaneously and independently. Each feeding jig 101 may be moved at a distance from the other so that no more than one feeding jig 101 enters the code-marking area or the code-scanning area at a time, and the work pieces may be independently and alternately coded or scanned.

Because each feeding clamp 101 moves along the respective linear guide rail 102, the feeding clamps 101 are mutually independent and can move respectively, so that the workpieces clamped by each feeding clamp 101 can be alternately coded, automatic circulation of a series of actions of feeding, coding, code scanning and material taking is facilitated, and the beat of a production line is also facilitated.

In some embodiments, with continued reference to fig. 2, 3 and 6, the feed mechanism 10 further includes at least two gripper drives 103 for respectively driving the respective feed grippers 101 along the linear guide 102.

The feeding mechanism 10 further includes a clamp driving member 103, and at least two clamp driving members 103 are provided. Alternatively, the clamp driving members 103 are disposed in one-to-one correspondence with the feeding clamps 101, and each clamp driving member 103 is connected to one feeding clamp 101 to drive the feeding clamp 101 to move along the first direction X. Also alternatively, one gripper driving member 103 connects at least two feeding grippers 101, so that the connected feeding grippers 101 move synchronously. Each feed jig 101 is spaced apart from each other in the first direction X by a distance that is sufficient to provide for the presence of only one feed jig 101 in the region of the code to be inscribed on the workpiece.

The clamp driving member 103 may be an air cylinder, and a cylinder barrel of the air cylinder is disposed at one end of the linear guide rail 102, and an end cover capable of moving along the first direction X is connected to the feeding clamp 101 to push and pull the feeding clamp 101 along the first direction X. The fixture driving member 103 may be a structure formed by matching a rolling screw with a motor, wherein a screw rod with threads on the surface extends along the first direction X, an output shaft of the motor is connected with the screw rod, a ball nut is sleeved on the screw rod, the feeding fixture 101 is connected with the ball nut, the motor drives the screw rod to rotate, and the ball nut drives the feeding fixture 101 to move along the first direction X. The clamp driving member 103 may also be in a structure form of matching a rack and a motor, the clamp driving member 103 may be any form or member capable of meeting the requirement of reciprocating the feeding clamp 101 along the first direction X, and the specific form of the clamp driving member 103 is not limited in any way.

Since the feeding mechanism 10 further includes the clamp driving member 103 for driving the feeding clamp 101 to move, the feeding clamp 101 can automatically move under the action of the clamp driving member 103, thereby facilitating the automation of the operation and reducing the labor burden. Since the jig driving members 103 are provided in one-to-one correspondence with the feeding jigs 101, respectively, it is convenient to control and debug the movement of each feeding jig 101, respectively.

In the process of moving along with the feeding clamp 101, the workpiece passes through the coding area of the coding mechanism 11 and then passes through the coding area of the coding mechanism 12. In the code etching area, the surface of the workpiece to be etched faces the code etching mechanism 11, the code etching mechanism 11 is used for etching the workpiece, and after the code etching is finished, the etched workpiece is sent to the code scanning area. In the code scanning area, the surface of the workpiece, which is already coded, needs to face the code scanning mechanism 12, and the code scanning mechanism 12 scans the workpiece.

Specifically, the coding mechanism 11 includes a coder, and the transmitting end of the coder needs to face the surface of the workpiece to be coded so as to code the workpiece. The code scanning mechanism 12 includes a code scanning gun 122, and the emitting end of the code scanning gun 122 is required to face the surface of the workpiece to be coded so as to scan the code. In order to simplify the operation steps, the emission end of the code scanning gun 122 and the emission end of the code marker face the same direction, so that the code marking and the code scanning can be realized without turning the workpiece.

Alternatively, the coding mechanism 11 and the code scanning mechanism 12 are disposed on the same side of the feeding mechanism 10 in the second direction Y, and the code scanning gun 122 and the code scanner may be disposed on the same side of the feeding mechanism 10 in the second direction Y or on the same side of the feeding mechanism 10 in the third direction Z. Also alternatively, the code marking mechanism 11 and the code scanning mechanism 12 are respectively arranged at two sides of the second direction Y of the feeding mechanism 10, and the code scanning gun 122 and the code marking device are positioned at the same side of the feeding mechanism 10 along the third direction Z.

The feeding mechanism 10, the coding mechanism 11, the code scanning mechanism 12 and the material taking mechanism 13 are all fixed on the ground, the first direction X and the second direction Y are mutually perpendicular and are parallel to the ground, and the third direction Z is perpendicular to the ground.

In the embodiment of the application, since each feeding clamp 101 moves along the respective linear guide rail 102, the feeding clamps 101 are independent of each other and can move respectively, so that the workpieces clamped by the feeding clamps 101 can be alternately coded, the automatic circulation of a series of actions of feeding, coding, code scanning and material taking can be realized, and the beat of a production line can be improved. Because the at least two feeding clamps 101 are arranged, and the feeding clamps 101 alternately pass through the coding mechanism 11, at the same time, at least two workpieces can be respectively subjected to different operations and only one workpiece is coded, especially at least two workpieces to be coded are alternately coded, the risk of repeated coding on different workpieces can be restrained, and the operation efficiency can be improved. In addition, when one of the feeding jigs 101 is damaged or maintained, a complete operation can be still realized through the other feeding jigs 101, which is helpful to reduce the influence of the stop caused by the damage or maintenance of the feeding jigs 101 on the production tact, the production efficiency and the like. Because the material taking mechanism 13 capable of picking up scanned workpieces on the material feeding clamp 101 is arranged, and the material feeding clamp 101 can reciprocate, the material feeding clamp 101 can be emptied by the material taking mechanism 13 so as to place new workpieces to be coded, and automatic circulation operation is realized. The feeding mechanism 10, the coding mechanism 11 and the code scanning mechanism 12 are arranged between the first position and the second position in a concentrated manner, so that the conveying route is simplified and shortened, and the occupied area of the device is reduced. Since the code scanning mechanism 12 and the code etching mechanism 11 are arranged on the same side along the second direction Y, the feeding clamp 101 can clamp the workpiece, the surface to be etched on the workpiece faces the code etching mechanism 11, and when the workpiece moves to the code scanning mechanism 12 after being etched, the surface of the workpiece etched with the code faces the code scanning mechanism 12, so that the workpiece does not need to be turned over, and the structure and the operation steps of the feeding clamp 101 are simplified.

In some embodiments, each feed jig 101 includes a workpiece placement groove, and the workpiece placement groove of each feed jig 101 is positioned differently along a third direction Z, which is perpendicular to the first direction X and the second direction Y, respectively; the code scanning mechanism 12 comprises a code scanning support 121 and at least two groups of code scanning guns 122 arranged on the code scanning support 121, wherein the positions of the groups of code scanning guns 122 along the third direction Z are different, and the code scanning guns are used for scanning the code of the coded workpieces in the workpiece placing grooves at the corresponding positions respectively.

The feed jig 101 includes a work placement groove. The workpiece placement groove comprises two first surfaces, and the first surfaces are arranged at intervals along the first direction X, so that the workpiece is limited between the two first surfaces. Alternatively, the two first surfaces are configured to be movable toward and away from each other to clamp or release the workpiece.

Further, the workpiece placement groove further comprises a second surface, and the second surface is used for bearing the workpiece. The first surfaces are arranged on the second surface at intervals along the first direction X. Optionally, the workpiece placement groove further includes a third surface perpendicular to the first surface and the second surface for limiting the workpiece in the second direction Y.

The positions of the workpiece placement grooves along the third direction Z are different, i.e., the workpiece placement grooves are located at different heights with respect to the ground. The workpiece placement grooves are arranged at different heights in the coding area, so that all workpieces on the workpiece placement grooves can be coded when passing through the coding area.

The code scanning mechanism 12 comprises a code scanning bracket 121 and a code scanning gun 122. The code scanning support 121 is used for supporting and fixing the code scanning gun 122, and the transmitting end of the code scanning gun 122 faces the feeding mechanism 10. At least two groups of code scanning guns 122 are arranged, and the height of each group of code scanning guns 122 corresponds to the height of one workpiece placing groove.

Because the feed jig 101 includes a workpiece placement groove, the workpiece can be stably held in the groove and can be held with a desired orientation of the code surface. Because the positions of the workpiece placement grooves in the third direction Z are different, each group of code scanning guns 122 corresponds to each workpiece placement groove one by one, and therefore each group of code scanning guns 122 can scan codes relatively independently, so that the workpieces in each feeding fixture 101 can be scanned without interference, and the production beat can be accelerated. The workpiece containing grooves with different code scanning requirements can be placed corresponding to the workpiece containing grooves in different positions, so that the code scanning requirements are met. In addition, at least two coded workpieces can be scanned simultaneously. In some embodiments, each feed jig 101 further includes a jig frame 1011 and a clamping plate 1012 provided on the jig frame 1011, the jig frame 1011 being slidably connected to the respective linear guide 102, the clamping plate 1012 being formed with a work placement groove.

The feed clamp 101 also includes a clamp bracket 1011 and a clamp plate 1012. One side of the third direction Z of the clamp bracket 1011 is connected to the clamping plate 1012, and the other side of the third direction Z of the clamp bracket 1011 is slidably connected to the linear guide 102. A workpiece placement groove is formed on a side of the clamping plate 1012 in the second direction Y near the coding mechanism 11. The height of the jig holders 1011 of each feeding jig 101 is different from each other so that the position of the work placement groove formed by each clamping plate 1012 in the third direction Z is different. The height of the clamp stand 1011 refers to the length of the clamp stand 1011 in the third direction Z.

Since the clamping plate 1012 is formed with the workpiece placement groove, the workpiece can be caught by the workpiece placement groove, thereby being stably fixed to the clamping plate 1012. Since the clamping plate 1012 is provided on the clamp bracket 1011, the clamp bracket 1011 is slidably connected to the linear guide 102, and thus the workpiece can be slid along the linear guide 102 with the clamp bracket 1011.

In some embodiments, each set of code scanner 122 includes a first code scanner and a second code scanner disposed along the first direction X for scanning the first identification code on the coded workpiece and the second identification code engraved by the engraving mechanism 11, respectively.

Optionally, each group of code scanner 122 includes a second code scanner for scanning the second identification code imprinted by the imprinting mechanism 11. Further, each set of code scanner 122 further includes a first code scanner for scanning the first identification code. The first identification code is an identification code of the workpiece, such as a charging code. The first identification code and the second identification code may be associated. After the coded workpiece reaches the code scanning area, the first code scanning gun and the second code scanning gun can respectively scan the first identification code and the second identification code on the workpiece at the same time.

Workpieces from different manufacturers or production lots may have different imprint locations for the first identification code. The first workpieces with the same marking positions can be placed in the same workpiece placing groove each time, and the setting positions of the first code scanning gun and the second code scanning gun correspond to the first identification code and the second identification code respectively in a group of code scanning guns 122 corresponding to the positions of the workpiece placing groove. And the other batch of second workpieces with different marking positions of the first identification codes of the first workpieces are placed in the other workpiece placing groove each time, and in a group of code scanning guns 122 corresponding to the positions of the workpiece placing grooves, the setting positions of the first code scanning gun and the second code scanning gun correspond to the first identification codes and the second identification codes respectively.

An opening is formed in one side surface of the bin shell, and the drawing box can be pulled out of the bin shell or pushed into the bin shell from the opening. The drawing box is constructed as a box body with one side open, and the opening faces one side of the third direction Z. The take-off mechanism 13 picks up the scan reject and places the reject into the box from the opening of the box. Optionally, a stop is configured within the cassette to stop the work piece in the cassette.

Because the coding device also comprises the waste bin 14, the unqualified workpieces subjected to coding scanning can be collected into the waste bin 14 in a concentrated mode so as to facilitate subsequent processing.

In some embodiments, as shown in fig. 1 to 3 and 6, the coding device further includes: and the turnover mechanism 15 is positioned on two opposite sides of the feeding mechanism 10 along the second direction Y, and the turnover mechanism 15 is used for receiving the qualified code scanning workpieces picked up by the material taking mechanism 13 and turning over the qualified code scanning workpieces.

In actual use, on the feeding mechanism 10, the surface of the workpiece to be coded faces to one side of the second direction Y close to the coding mechanism 11. The reclaimer mechanism 13 picks up the work piece without changing the orientation of the work piece, and the reclaimer mechanism 13 delivers the work piece to the scrap bin 14 or the turnover mechanism 15. The turnover mechanism 15 receives the workpiece and then turns the workpiece to any orientation, so that the surface of the workpiece which is carved with the code faces one side in the third direction Z, and the surface of the workpiece which is carved with the code faces one side of the second direction Y away from the carving mechanism 11.

Since the waste bin 14 and the turnover mechanism 15 are respectively located at two opposite sides of the feeding mechanism 10 along the second direction Y, classification of the code-scanning qualified workpieces and the code-scanning unqualified workpieces is achieved by controlling the material taking mechanism 13 to clamp the workpieces and then move towards the waste bin 14 or the turnover mechanism 15, and interference of moving paths of the code-scanning qualified workpieces and the code-scanning unqualified workpieces can be reduced. Because the turnover mechanism 15 is used for receiving the qualified code scanning workpiece picked up by the material picking mechanism 13, the code etching surface of the qualified code scanning workpiece can be turned from one side towards the code etching mechanism 11 along the second direction Y to other orientations, so that subsequent steps of picking, moving and the like can be conveniently performed.

One side of the turnover fixture 152 is hinged to the turnover bracket 151, and an air cylinder is arranged between the turnover bracket 151 and the turnover fixture 152 and is lifted to drive the turnover fixture 152 to turn.

Therefore, the qualified workpiece with the code scanning can be overturned along with the overturning clamp 152 after being fixed by the overturning clamp 152, and the situation that the qualified workpiece with the code scanning falls and deviates in the overturning process is avoided. The qualified work piece of yard can be overturned automatically under the effect of upset driving piece, helps realizing the automation of operation, reduces the manual work burden.

Because the material taking mechanism 13 comprises the material taking component 131 capable of moving along the second direction Y, and the waste bin 14 and the turnover mechanism 15 are respectively positioned on two opposite sides of the feeding mechanism 10 along the second direction Y, the material taking mechanism 13 can convey scanned workpieces to the waste bin 14 or the turnover mechanism 15, so that classification of the scanned qualified workpieces and the scanned unqualified workpieces is realized. Because the material taking assembly 131 can also move along the third direction Z, the material taking assembly 131 can pull out the workpiece from the feeding fixture 101, and can insert the workpiece into the waste bin 14 and the turnover mechanism 15, so that full-automatic operation is realized, and the manual burden is reduced.

Optionally, the take out assembly 131 includes a vacuum suction that is capable of sucking or releasing a workpiece.

Since the first reclaiming rail 132 extends along the second direction Y, the reclaiming bracket 133 is slidably connected to the first reclaiming rail 132, and thus the reclaiming bracket 133 is movable in the second direction Y. The material taking support 133 is provided with a second material taking guide rail 134 extending along the third direction Z, and the material taking driving member is slidably connected with the second material taking guide rail 134, so that the material taking driving member can move in the second direction Y and the third direction Z.

The following describes a method for using the coding device according to the embodiment of the present application with reference to the drawings.

FIG. 8 is a flow chart of an encoding method according to some embodiments of the present application; FIG. 9 is a flow chart of an example of a feeding step provided by some embodiments of the present application; fig. 10 is a flow chart of an example of a material taking step provided in some embodiments of the present application.

In a second aspect, as shown in fig. 8, the present application further provides a coding method, which is applied to the coding device described above, and includes:

s1: feeding: the feeding clamp of the feeding mechanism carries the workpiece to be coded to linearly move from a first position to a second position along a first direction;

s2: and (3) coding: when the feeding clamp carries the workpiece to be coded and moves into a coding area of the coding mechanism along a first direction, coding operation is carried out on the workpiece to be coded through the coding mechanism;

S3: a code scanning step: when the feeding clamp carries the coded workpiece and moves into a code scanning area of the code scanning mechanism along the first direction, the code scanning mechanism scans the code of the coded workpiece;

The code engraving mechanism and the code scanning mechanism are both positioned on the same side of the feeding mechanism along a second direction, and the second direction is perpendicular to the first direction;

s4: a material taking step: picking up scanned workpieces on a feeding clamp through a material taking mechanism;

In the feeding step S1, at least two feeding jigs carry respective workpieces to be coded alternately through the coding region of the coding mechanism.

Alternatively, during the movement of the feeding jig 101 carrying the workpiece to be coded, the movement is not continuous, and the feeding jig 101 may stay for a period of time when reaching the coding region, and continue to move after coding is completed.

Also optionally, the feeding jig 101 stays for a while when it reaches the code scanning area, and continues to move after the code scanning is completed.

After the feed gripper 101 reaches the second position, it remains for a period of time waiting for the take-off mechanism 13 to pick up the scanned workpiece.

When the feeding clamp 101 carries the workpiece to be coded and performs coding through the coding area, only one feeding clamp 101 is arranged in the coding area, after the feeding clamp 101 leaves the coding area, the next feeding clamp 101 carries the workpiece to be coded and performs coding through the coding area, and when the workpiece to be coded is coded each time, only one workpiece to be coded can exist in the coding area.

Thus, the workpiece to be coded is sequentially moved to the coding area and the code scanning area by the feeding clamp 101, and coding and code scanning of the workpiece are completed. And then the scanned workpieces are picked up by the material taking mechanism 13, so that the feeding clamp 101 can be free of a position capable of accommodating new workpieces to be coded, and continuous production is facilitated. The coding method is simple in steps, time-saving and labor-saving. Because the marking mechanism 11 can only mark one identification code each time, and the codes of each workpiece are different, the workpieces to be marked alternately pass through the marking areas, so that the marking mechanism 11 can mark the workpieces to be marked respectively, and the repeated marking is avoided.

In some embodiments, as shown in fig. 9, the feeding step S1 includes:

S12: and returning each empty feeding clamp from the second position to the first position so as to feed.

After the feeding clamp 101 reaches the second position, the material taking mechanism 13 takes away the scanned workpiece, so that the feeding clamp 101 is free of space. The empty feeding clamp 101 moves from the second position to the first position until the empty feeding clamp 101 stops after reaching the first position, and a new workpiece to be coded is clamped by using the feeding clamp 101.

After the empty feeding clamps 101 are restored, the feeding clamps can return to the first position, and the feeding clamps can not stop when returning to the code-engraving area and the code-scanning area. Optionally, the speed at which the feed clamp 101 returns from the second position to the first position is greater than the speed at which the feed clamp 101 moves from the first position to the second position.

Therefore, the first position is fed, the code carving and code scanning are completed in the moving process to the second position, the workpiece is taken out in the second position, the empty feeding clamp 101 is restored to return to the first position, the steps of feeding, the code carving and code scanning in the moving process and the workpiece taking out are repeated again, continuous production is realized, and the production efficiency is improved.

In some embodiments, as shown in fig. 10, the reclaiming step S4 includes:

S41: if the scanned code workpiece is unqualified, transferring the picked unqualified scanned code workpiece to a waste bin of the code engraving device through a material taking mechanism;

s42: and if the scanned code workpiece is qualified, transferring the picked qualified scanned code workpiece to a turnover mechanism of the code engraving device through the material taking mechanism.

If the scanned workpiece is unqualified, the material taking mechanism 13 transfers the picked unqualified scanned workpiece to a waste bin 14 of the coding device. A sensor is provided in the waste bin 14 and a warning is automatically given when the waste bin 14 is full.

If the scanned code workpiece is qualified, the picking-up qualified scanned code workpiece is transferred to a turnover mechanism 15 of the code engraving device through a material taking mechanism 13, and the turnover mechanism 15 turns over the scanned code workpiece.

Thus, the material taking mechanism 13 can sort the qualified workpieces with the scanned codes and the unqualified workpieces with the scanned codes, send the qualified workpieces with the scanned codes to the turnover mechanism 15, and send the unqualified workpieces with the scanned codes to the waste bin 14 so as to facilitate the later separate treatment.

In some embodiments, with continued reference to fig. 10, the method of encoding further includes:

s5: and (3) blanking: the turned workpiece on the turning mechanism is picked up by a blanking mechanism arranged on the coding device and transferred to the next station.

The blanking assembly 161 of the blanking mechanism 16 moves to the turnover mechanism 15 along the third direction Z, clamps the scanned workpiece, and moves away from the turnover mechanism 15 along the third direction Z. The blanking mechanism 16 moves the scanned workpiece to the next station along the second direction Y.

Thus, the blanking mechanism 16 picks up the workpiece that has been flipped to a position that meets the next station requirement, and the blanking mechanism 16 itself does not need to flip the workpiece again. After the blanking mechanism 16 picks up the workpiece, the turnover mechanism 15 vacates a position capable of accommodating a new workpiece, so that the production continuity is facilitated.

Alternatively, the coding fool-proofing method is applied to the coding device as described above.

For the information that can not be sent, an alarm prompt can be sent to remind an input person to correct the input information in time, so that the code-carving operation can be started in time.
