[0041] Working process and principle:

[0042] First according to the bumper to select the corresponding profiled block 14, then according to the width of the bumper to adjust the position of the slide plate 132, adjust from the blind hole 121 pull out the positioning column 139, then the slide plate 132 is slid to the corresponding position, and then the positioning column 139 is inserted into the blind hole 121, and the slide plate 132 is limited, so that the slide plate 132 is fixed at a position.

[0043] When the inclination angle of the positioning frame 130 needs to be adjusted, the hexagonal head at the end of the sleeve rotating screw rod 135 is rotated, the screw rod 135 is rotated to drive itself to extend and retract on the hinged frame 133, the screw rod 135 extends and retracts to adjust the position of the support member two 137 to the hinged frame 133, so that the positioning frame 130 can rotate around the hinged seat 138, thereby realizing the angle adjustment of the positioning frame 130, the positioning block 131 is installed to the positioning frame 130, and the side wall of the positioning frame 130 is provided with a threaded hole 1301 for fixing the positioning block 131.

[0044] After the assembly table 1 is ready, the assembly of different workpieces and the screwing process can be allocated to each station, then the rotary motor drives the chain wheel 23 to rotate, the connecting block two 18 on the chain 24 moves with the chain 24, and the connecting block two 18 drives the base frame 11 to move through the connecting shaft 17 and the connecting block one 16. When moving to the corner, the rotating relationship between the connecting block two 18 and the connecting shaft 17 can ensure the normal movement of the base frame 11, so as to transfer the bumper which has been partially assembled in the previous station to the next station. In this process, the universal wheel 19 is used for moving the assembly table 1.

[0045] When the bumper assembly is completed, the assembly table 1 where the bumper is located is rotated to the unloading device 3, then the driving motor 37 is started, the gear 371 is rotated, the meshing of the gear 371 and the rack 38 makes the sliding frame 31 move on the rack 30 to the direction of the assembly table 1, finally the supporting strip 321 of the unloading frame 32 is inserted into the bottom of the bumper, and the supporting strip 321 is located in the gap between the profiled block 14 and the profiled block 14 and the gap between the positioning block 131 and the profiled block 14.

[0046] After that, the cylinder 351 is started, and the block 341 drives the spline shaft 34 to move upward in the spline of the synchronous wheel 33, and the spline shaft 34 drives the unloading rack 32 to move upward, so that the bumper is lifted up by using the support bar 321, so that the bumper is separated from the contour block 14 and the positioning block 131. Then the driving motor 37 drives the gear 371 to reverse, so that the slide 31 moves outward to take out the bumper. Finally, the rotating motor 36 drives the synchronous wheel 2 361 to rotate, driving the synchronous wheel 1 33 to rotate, so that the spline shaft 34 inside the synchronous wheel 1 33 also rotates, realizing the angle adjustment of the unloader, facilitating the adjustment of the unloading rack 32 to a position aligned with the conveyor line, and then the bumper is lowered onto the conveyor line again.
