At the same time when the upper buckle 11 and the lower buckle 13 are pushed, the punching device 6 punches the tarpaulin 12. Specifically, the tarpaulin 12 (the tarpaulin is Figures 2-11The tarpaulin 12 extends along the X direction, and in the Z direction, the tarpaulin 12 is located between the upper module 61 and the lower module 62 of the punching device 6 and between the clamping part 511 and the lower die 507, that is, after the upper buckle 11 and the lower buckle 13 are pushed to the fastener positioning device 5, the upper buckle 11, the tarpaulin 12 (unpunched position) and the lower buckle 13 are arranged in sequence from top to bottom in the Z direction.

[0068] Referring to Figure 11 , the transverse driving mechanism 508 drives the moving seat 502 to move from the third position to the fourth position along the +X direction, so that the punching device 6 moves away from the hole position just punched on the tarpaulin 12 along the +X direction, the clamping part 511 and the lower die 507 move to the hole position just punched on the tarpaulin 12 along the +X direction, that is, at this time, the upper buckle 11, the hole position of the tarpaulin 12 and the lower buckle 13 are arranged in sequence from top to bottom in the Z direction, and the lower die 507 rises to the highest position under the action of the lifting part 504 and the transverse guide 503. Then, the lifting driving mechanism 510 drives the top core 509 to protrude upwardly from the lower die 507, and the top core 509 penetrates the lower buckle 13, the hole 121 of the tarpaulin 12 and the upper buckle 11 in sequence to center the three, and after centering, the clamping arm 5111 releases the upper buckle 11 to make it fall along the top core 509. Then, the top core 509 is lowered and reset, and the upper die of the buckling device is pressed downwardly to the lower die 507, so as to press the upper buckle 11, the tarpaulin 12 and the upper buckle 11 in sequence. After the buckling is completed, the upper die of the buckling device is raised upwardly, and the clamping arm 5111 is re-folded, at this time, the tarpaulin 12 is moved by one unit interval (that is, the distance between two adjacent hole 121) along the +X direction, so that the tarpaulin 12 part where the buckling is completed leaves the operation position, and the unprocessed tarpaulin 12 part enters the operation position, at the same time, the transverse driving mechanism 508 drives the moving seat 502 to move from the fourth position to the third position along the -X direction, and the next round of operation is performed.

[0069] All the driving mechanisms in the embodiment can be driving devices such as air cylinders, oil cylinders or motors, and specifically, the driving mechanisms in the embodiment adopt air cylinders.

[0070] The buckling device has the following technical effects:

[0071] I. When the fasteners are distributed, the movable blocking piece 24 is arranged to prevent the fasteners from directly falling and passing through the fixed blocking piece 23, and prevent too many fasteners from being accumulated on the upstream side of the fixed blocking piece 23, thereby solving the problem of poor fastener conveying or even blockage.

[0072] II. The first accommodating part 321 and the second accommodating part 322 are arranged to accommodate both the upper buckle 11 and the lower buckle 13, so that the fastener conveying device 3 is used for conveying the upper buckle 11 and the lower buckle 13, thereby reducing the cost of the buckling device and making the assembly simpler.

[0073] The guiding of the horizontal moving guide 503 to the horizontal moving part 506 makes the lower die 507 lift with the lifting of the lifting part 504, so as to position the fastener on the lower die 507 and make it accurately move to the position of the fastener pressing device for pressing processing. The design is reasonable, the structure is simple, the assembly and debugging are convenient, the friction is reduced during the movement, the damage to the mechanism is reduced, the abnormal sound is reduced, the stability of the mechanism movement is improved, and the service life is prolonged.

[0074] The above only describes some embodiments of the present application. For those skilled in the art, without departing from the inventive concept of the present application, a number of modifications and improvements can be made, or the above technical solutions can be freely combined, including freely combining the technical features of the above different embodiments, which all belong to the protection scope of the present application.
