These cross beams 4 provide an installation and fixing position for the pneumatic scissors 5; a plurality of pneumatic scissors 5 are installed on the cross beam 4. The pneumatic scissors 5 are the main cutting tools for automatically cutting the water inlet of the door trim handle box 15. The pneumatic scissors 5 are driven by air pressure to achieve fast and accurate cutting actions; two partition plates 6 are symmetrically installed above the inner cavity of the base cabinet 1. An activity groove 7 is formed between the two partition plates 6. A waste recycling component 8 is provided in the activity groove 7. The waste recycling component 8 is movably connected to the two partition plates 6.

The feeding end of the conveyor belt 9 penetrates through the side wall of the base cabinet 1 and extends to the lower part of the waste recycling component 8. The conveyor belt 9 is used to convey the trimmed door trim handle box 15 to a designated position; an outlet 10 is formed above the side adjacent to the conveyor belt 9 of the base cabinet 1. An inclined material guiding groove 11 is installed at the outlet 10. The feeding end of the material guiding groove 11 is arranged in the activity groove 7 to ensure that the waste can smoothly enter the material guiding groove 11. The discharging end of the material guiding groove 11 extends outwards, and a waste recycling box 12 is provided below the discharging end. The waste recycling box 12 is used to collect the water inlet waste led out by the material guiding groove 11; a transfer robot 13 is provided on one side of the base cabinet 1. A transfer frame 14 is provided at the front end of the movable arm of the transfer robot 13; the transfer frame 14 is used to carry and fix the door trim handle box 15 to be processed. The transfer robot 13 is used to cooperate with the transfer frame 14 to complete the automatic transfer work of the door trim handle box 15; this device automatically cuts the water inlet by the pneumatic scissors 5, the waste recycling component 8 collects the waste, and conveys the waste to the waste recycling box 12 through the material guiding groove 11, realizing the automatic operation of the water inlet cutting and waste treatment of the door trim handle box 15 and improving the overall production efficiency.

[0023] Please refer to Figures 2 to 4, as an embodiment of the present utility model, the waste recycling component 8 includes a trough-shaped material receiving plate 801, and both ends of the trough-shaped material receiving plate 801 are respectively slidably connected to two partition plates 6 symmetrically arranged in the inner cavity of the bottom cabinet 1; a guiding slide rail 802 is installed at the upper end of each partition plate 6, and the guiding slide rail 802 is arranged along the length direction of the partition plate 6. A guiding slider 803 adapted to the guiding slide rail 802 is provided at the lower end of the trough-shaped material receiving plate 801 on the side close to the partition plate 6; a magnetic coupling rodless cylinder 804 is installed on the partition plate 6 on one side of the inner cavity of the bottom cabinet 1, and a connecting member 805 is provided on the movable cylinder barrel of the magnetic coupling rodless cylinder 804, and the upper end of the connecting member 805 is fixedly connected to the trough-shaped material receiving plate 801.

[0024] In the above-mentioned solution, the trough-shaped material receiving plate 801 is designed as a groove shape to facilitate the collection of waste cut by the pneumatic scissors 5. Both ends of the trough-shaped material receiving plate 801 are respectively slidably connected to the partition plates 6 arranged on the two inner side walls of the inner cavity of the bottom cabinet 1, so that the trough-shaped material receiving plate 801 can reciprocate along the length direction of the partition plate 6; in order to ensure the stability and accuracy of the trough-shaped material receiving plate 801 during the movement, a guiding slide rail 802 is installed at the upper end of each partition plate 6, and the guiding slide rail 802 is arranged along the length direction of the partition plate 6, providing a clear path for the movement of the trough-shaped material receiving plate 801; a guiding slider 803 adapted to the guiding slide rail 802 is provided at the lower end of the trough-shaped material receiving plate 801 on the side close to the partition plate 6. When the trough-shaped material receiving plate 801 moves, the guiding slider 803 will slide along the guiding slide rail 802 to ensure the smooth movement of the trough-shaped material receiving plate 801; a magnetic coupling rodless cylinder 804 is installed on the partition plate 6 on one side of the inner cavity of the bottom cabinet 1. The magnetic coupling rodless cylinder 804 serves as a power source for driving the movement of the trough-shaped material receiving plate 801. The magnetic coupling rodless cylinder 804 has the advantages of compact structure, smooth movement, and easy control, and is very suitable for this kind of scenario that requires precise control; a connecting member 805 is provided on the movable cylinder barrel of the magnetic coupling rodless cylinder 804, and the upper end of the connecting member 805 is fixedly connected to the trough-shaped material receiving plate 801. When the magnetic coupling rodless cylinder 804 works, the movable cylinder barrel of the magnetic coupling rodless cylinder 804 will drive the trough-shaped material receiving plate 801 to reciprocate along the guiding slide rail 802 through the connecting member 805.

[0025] In use, first, the movable arm of the transfer robot 13 drives the transfer frame 14 to transfer the door trim handle box 15 to be sheared above the table top plate 2, and adjusts the position of the water inlet on the door trim handle box 15 to align it with the multiple pneumatic scissors 5 provided in the mounting opening 3. Then, control the pneumatic scissors 5 to automatically cut the water inlet of the door trim handle box 15. When the pneumatic scissors 5 cut the water inlet, the water inlet waste will directly fall from the mounting opening 3 onto the trough-shaped material receiving plate 801. At this time, the magnetic coupling rodless cylinder 804 is activated. The magnetic coupling rodless cylinder 804 drives the trough-shaped material receiving plate 801 to move along the guiding slide rail 802 towards one side of the guiding trough 11 through the connecting member 805. When the trough-shaped material receiving plate 801 moves to the upper end of the guiding trough 11, the telescopic cylinder 20 will drive the push plate 17 to move, and push the water inlet waste on the trough-shaped material receiving plate 801 into the guiding trough 11, and the guiding trough 11 will convey the water inlet waste to the waste recycling box 12. As the trough-shaped material receiving plate 801 moves, the conveyor belt 9 provided below the trough-shaped material receiving plate 801 will be gradually exposed, facilitating the direct fall of the door trim handle box 15 from the mounting opening 3 onto the conveyor belt 9, and transporting it to the designated position through the conveyor belt 9. Then, the magnetic coupling rodless cylinder 804 will move in the reverse direction and drive the trough-shaped material receiving plate 801 back to the initial position to prepare for receiving the next batch of water inlet waste. Through the waste recycling component 8 designed as above, the waste can be automatically and efficiently collected and transferred, improving the automation degree and efficiency of the entire production process.

[0026] Please refer to Figure 3 , Figure 4 , as an embodiment of the present utility model, a lower groove 16 is provided in the middle of the trough-shaped material receiving plate 801, and a push plate 17 is provided in the lower groove 16. Guide rods 18 are respectively provided at both ends of the push plate 17, and guiding grooves 19 adapted to the guide rods 18 are provided on both sides of the lower groove 16. A telescopic cylinder 20 is installed outside the trough-shaped material receiving plate 801, and the guide rods 18 penetrate through the guiding grooves 19 and are fixedly connected to the top end of the piston rod of the telescopic cylinder 20.

[0027] In the above-described solution, a lower groove 16 is provided in the middle of the trough-shaped material receiving plate 801. The main purpose of the lower groove 16 is to accommodate the push plate 17 and the gate waste collected during the cutting process. The push plate 17 arranged in the lower groove 16 is mainly used to push the gate waste collected in the lower groove 16 to a designated position. The design of the push plate 17 makes the transfer of the gate waste more direct and efficient, reducing the residence time of the gate waste in the trough-shaped material receiving plate 801. Guide rods 18 are respectively provided at both ends of the push plate 17, and these guide rods 18 provide stable guidance for the movement of the push plate 17. At the same time, guide grooves 19 adapted to the guide rods 18 are provided on both sides of the lower groove 16, and the guide rods 18 slide in the guide grooves 19, thereby ensuring the stability and accuracy of the push plate 17 during the movement process. A telescopic cylinder 20 is installed outside the trough-shaped material receiving plate 801, and this telescopic cylinder 20 provides power for the movement of the push plate 17. The guide rod 18 provided at one end of the push plate 17 passes through the guide groove 19 and is fixedly connected to the top end of the piston rod of the telescopic cylinder 20. When the piston rod of the telescopic cylinder 20 expands and contracts, it drives the push plate 17 to move in the lower groove 16 through the guide rod 18.

[0028] Specific working process: During the process of the pneumatic scissors 5 cutting the gate of the door trim handle box 15, the gate waste will fall into the lower groove 16 of the trough-shaped material receiving plate 801. The telescopic cylinder 20 starts to work, and the piston rod of this telescopic cylinder 20 contracts inward, driving the guide rod 18 and the push plate 17 to move in the lower groove 16, so that the push plate 17 pushes the gate waste in the lower groove 16 to the feeding end of the material guiding groove 11 for subsequent waste treatment. After the push plate 17 finishes pushing the gate waste, the piston rod of the telescopic cylinder 20 extends outward, further driving the guide rod 18 and the push plate 17 back to the initial position to prepare for receiving the next batch of gate waste. The trough-shaped material receiving plate 801 can not only effectively collect waste, but also automatically and efficiently transfer waste, further improving the automation degree and efficiency of the entire production process.

[0029] Please refer to Figure 2 , as an embodiment of the present utility model, the bottom of the lower groove 16 abuts against the upper surface of the feeding end of the material guiding groove 11, and the width of the lower groove 16 is smaller than the width of the feeding end of the material guiding groove 11.

[0030] In the above-described solution, the bottom of the lower groove 16 is closely attached to the upper surface of the feeding end of the material guiding groove 11. This abutting design ensures that the sprue waste will not leak or scatter during the pushing process. Since the width of the lower groove 16 is smaller than the width of the feeding end of the material guiding groove 11, this creates a wide entrance, facilitating the unobstructed entry of the sprue waste into the material guiding groove 11. When the telescopic cylinder 20 drives the push plate 17 to push the sprue waste from the lower groove 16 towards the material guiding groove 11, due to the close docking of the lower groove 16 and the feeding end of the material guiding groove 11, the sprue waste can smoothly slide from the lower groove 16 into the material guiding groove 11 without being blocked or scattered due to structural mismatches. The width of the material guiding groove 11 is larger than that of the lower groove 16, which means that even if the sprue waste spreads to a certain extent during the pushing process, it can still smoothly enter the material guiding groove 11 without being restricted by the edges, reducing the resistance of the sprue waste during the transfer process and ensuring the smoothness of the flow. Once the sprue waste is pushed into the material guiding groove 11, it can slide along the inclined material guiding groove 11 towards the waste recycling bin 12, realizing automatic waste treatment.

[0031] Please refer to Figure 1 , as an embodiment of the present utility model, adjustable feet 21 are respectively installed at the four corner positions of the bottom of the base cabinet 1.

[0032] In the above-described solution, the adjustable feet 21 installed at the four corner positions of the bottom of the base cabinet 1 can, under different ground conditions, ensure the horizontal placement of the base cabinet 1 and the entire device by adjusting their heights, which is beneficial to improving the stability of the device and preventing safety accidents or equipment damage caused by shaking or tilting during operation.
