The stepping push rod is elastically rotated. When the stepping push rod moves one station along the running direction of the conveyor line, the buffer push claw is stuck on the rear side wall of the buffer workpiece 12 and drives the buffer workpiece 12 to move forward one station. When the stepping push rod moves one station in the opposite direction of the conveyor line, the buffer push claw will be pressed into the stepping push rod by the buffer workpiece 12 behind until the buffer push claw moves to the rear side of the buffer workpiece 12 behind. At this time, the buffer push claw pops out again, and then when the stepping push rod continues to move forward one station along the running direction of the conveyor line, the buffer push claw will push the buffer workpiece 12 behind to continue to push forward one station. This reciprocating operation realizes the stepping transportation of the buffer workpiece 12 on the conveyor line.

[0029] As for the structure of the conveyor line, please refer to the attached Figure 2As shown, a feed pushing unit 5 and a slave plate collecting module 4 are respectively arranged on both sides of the starting end of the decomposition conveyor line 1, and the feed pushing unit 5 includes a buffer pushing device 501 and a slave plate pushing device 502. In a normal operation scenario, the feed pushing unit 5 is generally arranged on one side of the hook-buffer decomposition machine, and the hook-buffer decomposition machine can split the hook-buffer into several parts, wherein the buffer workpiece 12 and the slave plate workpiece 13 are pushed to the buffer maintenance conveyor line in this embodiment by the feed pushing unit 5 for maintenance work, wherein the buffer pushing device 501 is used to push the buffer workpiece 12 to the decomposition conveyor Line 1, and the slave plate pushing device 502 is used to push the slave plate workpiece 13 to the slave plate collecting module 4 for further operation.

Refer to the attached Figure 6 As shown, the first buffer flipping device 6 includes a first flip base 601, the first flip base 601 is rotatably provided with a first flip frame 602 and a first flip driving device 603 that drives the first flip frame 602 to rotate, the buffer workpiece 12 is conveyed to the first flip frame 602 at the end of the decomposition conveyor line 1, and then the first flip frame 602 rotates 90 degrees to stand up the buffer workpiece 12 that was originally laid flat, and then is brought to the pin-changing conveyor line 2 by the stepping and pushing mechanism of the pin-changing conveyor line 2;

A second buffer turning device 9 is arranged between the end of the pin-changing conveyor line 2 and the starting end of the conveyor line 3 to be assembled. Figure 7As shown, the second buffer flipping device 9 includes a second flip base 901, and the second flip base 901 is rotatably provided with a second flip frame 902 and a second flip driving device 903 driving the second flip frame 902 to rotate.

[0031] See attached Figure 4 ~Attached Figure 5 As shown, a sheet material feeding module 11 is provided at the end of the to-be-assembled conveyor line 3, and the sheet material feeding module 11 includes a sheet material feeding box 1101, a loading box pushing device 1103 is provided on one side of the loading box 1101, and a sheet material pushing device 1102 is provided at the bottom of the loading box 1101.

Generally, the conveyor line discharge pushing device 10 directly pushes the assembled buffer workpiece 12 and the plate workpiece 13 to the hook buffer assembly machine, which reduces the intermediate transportation process. After the buffer workpiece 12 has been reversed twice, the direction of the buffer workpiece 12 is opposite to that on the disassembly conveyor line 1, which is also beneficial to the operation of the hook buffer assembly machine.

[0032] The collection box pushing device, buffer pushing device 501, plate pushing device 502, first flipping drive device 603, pressure head driving device 702, second flipping drive device 903, conveyor line discharge pushing device 10, plate feeding pushing device 1102, loading box pushing device 1103 and stepping drive cylinder mentioned in this embodiment are all hydraulic drive cylinder mechanisms. At the same time, other similar devices that can achieve the same driving function, such as linear motors, starting cylinders, screw mechanisms, etc. can be applied to the solution of the utility model as needed.

[0033] The working principle of this embodiment is as follows:

[0034] During the loading process, the buffer pushing device 501 and the slave plate pushing device 502 push the buffer workpiece 12 on the hook buffer disassembly machine and the slave plate workpiece 13 to the disassembly conveyor line 1 and the slave plate collection box 401 respectively. During the conveying process of the conveyor line, whenever a buffer workpiece 12 is pushed to the disassembly conveyor line 1, the stepping pushing mechanism of the disassembly conveyor line 1, the pin exchange conveyor line 2 and the assembly conveyor line 3 pushes the buffer workpiece 12 on the conveyor line forward one station. The buffer workpiece 12 is transferred between the disassembly conveyor line 1 and the pin exchange conveyor line 2 by the first buffer flipping device 6. The buffer workpiece 12 is rotated 90 degrees and placed vertically on the pin exchange conveyor line 2. When the buffer workpiece 12 is conveyed to the bottom of the pin exchange press 7 on the pin exchange conveyor line 2, the pressure head driving device 702 is started to drive the buffer pressure head 701 to press down. After the buffer workpiece 12 is compressed to the specified position, the buffer is replaced. The shear pin of the buffer workpiece 12 is then driven to lift the buffer pressure head 701, and then the buffer workpiece 12 is conveyed to the free height measuring device 8, and the height dimension of the buffer workpiece 12 is measured and calculated by the distance sensor. At this time, the free height measuring device 8 can transmit the data back to the controller for identification to see whether it is qualified, and then the buffer workpiece 12 is transferred between the pin replacement conveyor line 2 and the conveyor line 3 to be assembled by the second buffer flipping device 9. The buffer workpiece 12 is rotated 90 degrees again and placed flat on the conveyor line 3 to be assembled. When the buffer workpiece 12 is conveyed to the end of the conveyor line 3 to be assembled, the plate material pushing device 1102 pushes a good plate workpiece 13 from the plate material box 1101 to one side of the buffer workpiece 12 and is combined with the buffer workpiece 12. Finally, the combination of the buffer workpiece 12 and the plate workpiece 13 is pushed out of the conveyor line to the hook buffer assembly machine for assembly through the conveyor line discharge pushing device 10.
