In this embodiment, the processing buffer device 1 at least includes a fixing and mounting mechanism 10, a lifting assembly 20 and a clamping assembly 30. The fixing and mounting mechanism 10 is used for fixing the processing buffer device 1 to the side 91 of the conveying line 9. In other embodiments, the processing buffer apparatus 1 is compatible with a plurality of transport lines 9, and the utility model is not limited thereto. In the embodiment, the jacking assembly 20 is disposed on the fixed mounting mechanism 10. The jacking assembly 20 comprises a jacking cylinder 21 and a connecting piece 22, and the jacking assembly 20 can move up and down in the vertical direction, such as the Z-axis direction, under the action of the jacking cylinder 21. The gripping assembly 30 is slidably disposed on the fixed mounting mechanism 10, and includes a horizontal displacement cylinder 32 and a pair of

gripping jaws

31a and 31 b. Gripping assembly 30 is connected to jacking assembly 20 by connector 22. The gripping member 30 is driven by the jacking member 20 to move to a rising threshold position (as shown in fig. 3 or fig. 4B) or a falling threshold position (as shown in fig. 1 or fig. 4A) relative to the fixed mounting mechanism 10. In the present embodiment, the clamping

jaws

31a and 31b are detachably disposed on two opposite sides of the horizontal displacement cylinder 32, and are driven by the horizontal displacement cylinder 32 to clamp or release the carrier 8 on the conveying line 9.

In this embodiment, the processing buffer apparatus 1 further includes a logic controller 40 electrically connected to the lifting assembly 20 and the gripping assembly 30, and controlling the output state of the lifting cylinder 21 of the lifting assembly 20 and the output state of the horizontal displacement cylinder 32 of the gripping assembly 30. In the present embodiment, the lift assembly 20 includes a first sensor 23 electrically connected to the logic controller 40 for sensing a critical position of the lift assembly 20 and transmitting a corresponding lift cylinder in-place signal to the logic controller 40. In the present embodiment, the clamping assembly 30 further includes a second sensor 33 electrically connected to the logic controller 40, wherein the second sensor 33 is used for sensing a relative horizontal distance between the pair of clamping

jaws

31a, 31b, such as the X-axis direction, when the clamping

jaws

31a, 31b perform the clamping operation or the releasing operation, and transmitting a corresponding distance interval signal to the logic controller 40, so as to precisely control the clamping

jaws

31a, 31b to perform the clamping operation or the releasing operation on the carrier 8. It should be noted that, in the present embodiment, the clamping

jaws

31a and 31b are detachably connected to the horizontal displacement cylinder 32, so that they can be detached from and replaced on the horizontal displacement cylinder 32. Accordingly, clamping

jaws

31a, 31b of corresponding length can be fitted for carriers 8 of different length. When the product process is not changed and only the length of the carrier 8 of the product is different, the matched clamping

jaws

31a and 31b can be directly replaced to continue the production. In the present embodiment, the clamping assembly 30 includes a plurality of holes 35 disposed at intervals on the clamping

jaws

31a and 31 b. In other words, the

jaws

31a, 31b may be of a honeycomb design to reduce the weight of the

jaws

31a, 31 b.

In the embodiment, the first sensor 23 of the lift assembly 20 includes a first sensing point 231 and a second sensing point 232. In the present embodiment, the first sensing point 231 and the second sensing point 232 are respectively disposed at two opposite upper and lower ends of the jacking cylinder 21, and are electrically connected to the logic controller 40. The first sensing point 231 of the first sensor 23 is used for sensing that the gripping assembly 30 is driven by the lifting assembly 20 to move to a lifting threshold position (as shown in fig. 3 or fig. 4B), and transmitting a lifting cylinder lifting-to-position signal to the logic controller 40. In addition, the first sensor 23 and the second sensor 232 are used for sensing that the lifting cylinder is driven by the lifting assembly 20 to move to the lowering threshold position (as shown in fig. 1 or fig. 4A), and transmitting a lifting cylinder lowering position signal to the logic controller 40. In other words, when the lift module 20 is lifted to the lift threshold position, the first sensor 23 detects the signal at the first sensing point 231. When the lifting assembly 20 is lowered to the lowering threshold position, the first sensor 23 detects a signal at the second sensing point 232. Of course, it should be understood by those skilled in the art that two sensors may be used to respectively sense the ascending threshold position and the descending threshold position of the lifting assembly. The present invention does not limit the kind of sensor. When the lifting unit 20 is lowered to the lowering critical position, as shown in fig. 4A, the clamping

jaws

31a and 31b of the gripping unit 30 are just at the same height as the carrier 8 on the conveying line 9, and the clamping

jaws

31a and 31b can just grip the carrier 8 when performing the gripping operation. When the lifting assembly 20 is lifted to the lifting critical position, as shown in fig. 4B, the carrier 8 is held by the clamping assembly 30 and lifted to the height, which facilitates the robot to perform corresponding processing actions, such as gluing, locking screws, welding or visual inspection. Of course, the present invention is not limited to the type of process cache. In addition, in the embodiment, the lifting assembly 20 is connected to the lifting cylinder 21 and the gripping assembly 30 through a connecting member 22, such as a connecting rod, so that the lifting assembly 20 can drive the gripping assembly 30 to move between the ascending critical position and the descending critical position. Of course, other ways of actuating the gripping assembly 30 by the jacking assembly 20 are suitable for use in the present invention. The present invention is not limited thereto and will not be described in detail.

In the embodiment, the processing buffer device 1 further includes a spring buffer 50 disposed at the top end of the fixing and mounting mechanism 10 and spatially opposite to the clamping assembly 30, wherein when the clamping assembly 30 clamps the carrier 8 and moves to the ascending critical position, as shown in fig. 4B, the spring buffer 50 abuts against the clamping assembly 30 to achieve the buffering and limiting function of the jacking cylinder 21, so as to prevent the clamping assembly 30 from shaking when the jacking cylinder 21 is in place. In addition, in the present embodiment, the fixing and mounting mechanism 10 includes fixing portions 14 located at two opposite sides of the fixing and mounting mechanism 10, for detachably fixing the processing buffer device 1 to the side 91 of the conveying line 9. The fixing portion 14 and the side 91 of the conveying line 9 can be fastened by, for example, a nut to quickly mount the processing buffer device 1 on the designated position of the conveying line 9. Of course, the utility model is not so limited.

In the present embodiment, the distance interval signal sensed by the second sensor 33 when the clamping operation or the releasing operation is performed on the clamping

jaws

31a and 31b, the lifting cylinder up-to-position signal sensed when the first sensing point 231 of the first sensor 23 is driven by the lifting assembly 20 to move to the lifting critical position by the clamping assembly 30, and the lifting cylinder down-to-position signal sensed when the second sensing point 232 of the first sensor 23 is driven by the lifting assembly 20 to move to the lowering critical position by the clamping assembly 30 are both transmitted to the logic controller 40. Therefore, the logic controller 40 can control the output states of the horizontal displacement cylinder 32 of the clamping assembly 30 and the jacking cylinder 21 of the jacking assembly 20. In this embodiment, the processing buffer apparatus 1 may include a carrying portion 11, wherein the logic controller 40 may be disposed on the carrying portion 11, which is not limited in the present invention. In addition, the bearing part 11 can be connected to the bottom end of the fixed mounting mechanism 10 or the bottom end of the jacking assembly 20. In other embodiments, the logic controller 40 may be installed inside or outside the processing buffer device 1, and may move together with the processing buffer device 1 to change the installation position on the transport line 9. The utility model is not limited thereto. In addition, the communication mode of the logic controller 40 may be a wired mode including but not limited to RS485, CAN, Internet, etc., or a wireless transmission including but not limited to wifi, lora, 5G, etc. In this embodiment, the logic controller 40 of the processing buffer device 1 may be connected to the controller of the transmission line 9 or other functional modules through a data communication bus, and the data communication bus and the power supply line are connected in a one-cable connection manner. In this embodiment, the processing buffer device 1 further includes an input interface 12 and an output interface 13, which are respectively disposed on two opposite sides of the carrying portion, and can be electrically connected to an adjacent processing buffer device (not shown) through the input interface 12 or the output interface 13. In this embodiment, the input interface 12 and the output interface 13 may be one-cable connectors. The input interface 12 can be used as an input port of a power line and a communication bus, and the output interface 13 can be used as an output port for connecting other modules. The upper control system belonging to the processing buffer device 1 and the conveying line 9 can further set the conveying state of the carrier 8 according to the production process state of the carrier 8, such as processing position buffer, processing completion, etc. The logic controller 40 of the processing cache apparatus 1 receives a transmission instruction from the upper control system and performs a predetermined function. For example, when receiving a command for buffering a carrier processing location, the logic controller 40 of the processing buffer apparatus 1 can control the lifting assembly 20 to descend, and the waiting gripping assembly 30 performs a gripping operation of the carrier 8 to grip the carrier 8 and then ascends to the ascending critical position. If the machining is completed, the jacking assembly 20 descends to the descending critical position, waits for the gripping assembly 30 to perform the releasing operation to release the carrier 8, and then ascends to the ascending critical position.

In the present embodiment, the conveying line 9 includes a pair of conveying belts 90, a carrier sensor 93, a blocking cylinder assembly 94 and a fixing member 92. The conveyor belt 90 is parallel to the side 91 of the conveyor line 9 and is used for carrying and transporting the carriers 8. The fixing member 92 is disposed on a path of the carrier 8 transported by the transport line 9, and the carrier sensor 93 and the stop cylinder assembly 94 are disposed on the fixing member 92, respectively. The carrier sensor 93 is used for sensing the position of the carrier 8 relative to the processing buffer device 1, and the blocking cylinder assembly 94 is used for assembling the blocking carrier 8 so that the carrier 8 is aligned between the clamping

jaws

31a and 31 b. In order to prepare the carrier 8 to align with the clamping

jaws

31a, 31b, in the embodiment, the carrier 8 includes a positioning groove 81 disposed on the periphery of the carrier 8 and spatially opposite to the blocking cylinder assembly 94, so that when the blocking cylinder assembly 94 engages with the positioning groove 81, the carrier 8 is ready to align between the clamping

jaws

31a, 31 b. In the present embodiment, the carrier sensor 93 can acquire signals and control the blocking cylinder assembly 94 through a controller of the conveyor line, and can also be implemented through the logic controller 40 of the processing buffer device 1. The utility model is not limited thereto. In addition, in the present embodiment, the gripping assembly 30 further includes a pair of protruding members 34 disposed on the clamping

jaws

31a and 31 b. The carrier 8 includes a pair of recesses 82 disposed on opposite sides of the carrier 8 and spatially opposite the protrusions 34, respectively.

In addition, in the embodiment, the carrier 8 may also be a weighing tray, which includes a load cell 83. The processing buffer device 1 further comprises a data port 60 disposed at the top end of the fixed mounting mechanism 10, electrically connected to the logic controller 40, and spatially opposite to the gripping assembly 30. When the gripping assembly 30 grips the carrier 8 and moves to the ascending critical position, the logic controller 40 can read the carrier weight data of the load cell 83 through the data port 60 and feed the data back to the upper control system. The present invention is not limited thereto and will not be described in detail.

FIG. 5 is a schematic diagram of a processing cache device according to a preferred embodiment of the present invention with a layout of multiple processing cache bits. In the present embodiment, two processing buffer devices 1a and 1b are respectively configured on the

conveyor lines

9a and 9b connected in series. The processing buffer devices 1a and 1b can be used for performing a certain processing process, such as gluing, locking screws, welding or visual inspection, for example, in cooperation with the

carriers

8a and 8b on the conveying

lines

9a and 9b, respectively. When the production process needs to be modified, for example, after the processing of the screw locking is completed by matching the processing cache devices 1a and 1b, glue coating needs to be added, on the

conveyor lines

9a and 9b connected in series, the processing cache device 1a can be matched to perform screw locking operation, and the processing cache device 1b can be matched to perform glue coating operation. Therefore, in the production line, when the processing cache device 1b cooperates with the carrier 8b for gluing, the processing cache device 1a cooperates with the carrier 8a for locking the screw. In other embodiments, if a process such as welding is required, a processing station buffer device installed on the linear transport module may be directly added and associated equipment for performing welding may be provided, so as to quickly adjust the layout of the production line. In this embodiment, one processing buffer device 1a is installed on the side of the conveyor line 9a, and one processing buffer device 1b is installed on the side of the conveyor line 9b to connect the two

conveyor lines

9a and 9b in series into a line, so that the

carriers

8a and 8b can be transported on the

conveyor lines

9a and 9 b. After the clamping carrier 8b of the processing cache device 1b is lifted to the right position, the relevant gluing equipment can operate the processing cache device. In other embodiments, if the

carriers

8a and 8b are weighing trays, the weight change of the glue can be fed back in real time. In other embodiments, the upper control system may configure the device IDs of the process cache devices 1a and 1b, so as to implement the cooperative use of multiple process cache bits. For example, the processing buffer device 1a is configured as No. 1, and the processing buffer device 1b is configured as No. 2. In an embodiment, if the processing buffer device 1b takes a long time to perform the gluing operation on the carrier 8b during the production process, and the equipment after the processing buffer device 1a completes the locking operation of the carrier 8a for a long time is idle, a new gluing processing position buffer device can be directly added to the side surface of the conveying line module to adjust the production cycle of the production line.

As can be seen from the above, the application range of the modular

processing buffer devices

1, 1a, and 1b configured on the

conveyor lines

9, 9a, and 9b for processing buffer is wide, and the

processing buffer devices

1, 1a, and 1b can be freely configured on the

conveyor lines

9, 9a, and 9b or omitted according to different production line requirements. Of course, the

processing buffer devices

1, 1a, 1b and the conveying

lines

9, 9a, 9b of the present invention may be combined to change the aforementioned technical features according to the actual application requirements. The present invention is not limited thereto and will not be described in detail.

In summary, the present invention provides a processing buffer device compatible with various transmission lines, which is applied to the transmission lines. The device has low cost and good compatibility with a conveying line, and can realize the operation control of clamping, jacking and the like of the carrier on the conveying line.
