[0090] d. Buckle fixing: The buckle is fixed to the buckle fixing groove 132 on the buckle fixing plate 130 in sequence through the buckle feeding tray 610, the induction device 700 and the electric slide rail 131.

[0091] Specifically, the buckle enters the buckle through slot 731 and is squeezed by the buckle at the rear, so that the bottom of the buckle is close to the blocking sheet 711, and then the horizontal cylinder 740 pushes the feed block 730 to move to the position of the longitudinal cylinder 750, and then the longitudinal cylinder 750 pushes the pushing sheet 751 to push the buckle into the buckle fixing slot 132, and then the longitudinal cylinder 750 is reset, and the horizontal cylinder 740 is reset. At this time, the infrared sensing head 720 senses that there is no buckle at the position of the buckle through slot 731, and then the buckle feed tray 610 is started, and the buckle is pushed into the buckle through slot 731, and then the infrared sensing head 720 senses the buckle and stops the buckle feed tray 610 from working.

[0092] At this time, the electric slide rail 131 pushes the buckle fixing plate 130 to move, and sends the buckle fixing grooves 132 without buckles to the position of the longitudinal cylinder 750 in turn. When all the buckle fixing grooves 132 are placed with buckles, the electric slide rail 131 drives the buckle fixing plate 130 to move to the position of the adsorption head 120, and then the piston rod of the vertical cylinder 140 drives the adsorption head 120 to descend, the adsorption head 120 adsorbs the buckle, and then the vertical cylinder 140 resets.

[0093] Then the cylinder 150 is pushed to push the suction head 120 with the buckle to move to just above the sealing strip, and then the piston rod of the vertical cylinder 140 drives the suction head 120 to descend, inserting the buckle into the circular hole 312 cut out of the sealing strip in step b, the suction head 120 releases the buckle, and then the vertical cylinder 140 is reset.

[0094] e. Buckle pressing: the vertical cylinder 140 descends to press the buckle, and then the vertical cylinder 140 is reset;

[0095] f. Second waste removal and reset: Push cylinder 150, clamping cylinder 320, front blanking cylinder 330, hole blanking cylinder 340 are reset, and at the same time, left and right blanking cylinders 350 are opened, so that the waste falls onto synchronous belt mechanism 410 through blanking channel 503, and then left and right blanking cylinders 350 are reset.

[0096] S4. Take out the sealing strip manually and then store the sealing strip.

[0097] After the waste materials discharged for the first and second times fall onto the synchronous belt mechanism 410 , the stepper motor 411 is controlled by the numerical control system 800 . The stepper motor 411 works for a period of time at a certain time to discharge the waste materials into the waste collection box 420 .

[0098] In summary, the above-mentioned embodiments are not limitative embodiments of the present invention, and any modifications or equivalent variations made by those skilled in the art on the basis of the essential contents of the present invention are within the technical scope of the present invention.
