[0031] The processing equipment 2 is embedded inside the front outer wall of the lower rack 3;

[0032] The front outer wall of the processing device 2 is embedded with a human-machine interface 1;

[0033] The inner walls at both ends of the lower frame 3 are equipped with second conveyor belts 11 to transport empty containers outwards. The inner walls at both ends of the upper frame 5 are equipped with first conveyor belts 10 to transport containers loaded with materials to the left. The lower frame 3 is equipped with a first drive motor 19. The left side of the first drive motor 19 is connected to a first drive rod 20. The upper outer wall of the first drive rod 20 is fixedly connected to a lifting plate 21. The upper outer wall of the lifting plate 21 is fixedly connected to a carrying plate 6 to lift the empty container downwards. When the operator starts the feeding program on the human-machine interface 1, the corresponding motor of the first conveyor belt 10 of the upper frame 5 starts, driving the first conveyor belt 10 to move. 0. The loading carrier starts to move to the left. After moving to the designated position, it flows to the pick-and-place machine to pick up the material for placement and production. After the material on the carrier is picked up, the empty carrier moves to the upper side of the carrying plate 6 under the drive of the first conveyor belt 10. Then the first drive motor 19 starts to work and drives the first drive rod 20 to rotate through the coupling. When the first drive rod 20 rotates counterclockwise, it drives the lifting plate 21 and the carrying plate 6 to move down. When the carrying plate 6 drives the empty carrier down to the second conveyor belt 11, the second conveyor belt 11 contacts the empty carrier and drives the empty carrier to move to the right and discharge it from the gap between the lower frame 3 and the upper frame 5.

[0034] A guide plate 12 is fixedly connected to the outer wall of the right end of the lower frame 3 to guide the direction of the empty vehicles. A collection bucket 15 is set on the right side of the guide plate 12 to collect the empty vehicles guided by the guide plate 12. The empty vehicles conveyed from the second conveyor belt 11 change direction under the guidance of the guide plate 12 and slide to the right into the collection bucket 15 for collection. When the number of empty vehicles in the collection bucket 15 reaches a certain amount, the collection bucket 15 can be taken out and the empty vehicles can be collected and recycled.

[0035] like Figure 1 As shown, a slide bar 14 is slidably connected to the inner side of the right outer wall of the guide plate 12, and a fixed frame 16 is fixedly connected to the outer side of the right end of the slide bar 14 to limit the placement position of the collection bucket 15. Limiting plates 13 are fixedly connected to the upper outer wall of the guide plate 12 and near the front and rear sides to limit the movement position of the empty vehicle. An opening 25 is provided inside the outer wall of the rear end of the fixed frame 16. Handles 17 are fixedly connected to the upper outer wall and the rear outer wall of the collection bucket 15 to drive the collection bucket 15 to move.

[0036] The slider 14 can slide inside the corresponding track inside the guide plate 12. After the slider 14 slides into the track, the position of the fixed frame 16 can be restricted. The collection bucket 15 can be placed inside the fixed frame 16. When the empty container inside the collection bucket 15 is full, the collection bucket 15 can be taken out from inside the fixed frame 16 by grabbing the two handles 17.

[0037] like Figure 5 and Figure 6 As shown, the left outer wall of the lower frame 3 and the left and right outer walls of the upper frame 5 are provided with fixed shafts 27. Fixed handles 26 are provided between the interiors of the multiple fixed shafts 27. The lower outer wall of the multiple fixed handles 26 is provided with a downward-opening groove 28. Multiple springs 29 are fixedly connected to the upper inner wall of the multiple grooves 28. Movable plates 30 are fixedly connected between the lower outer walls of the multiple springs 29.

[0038] When the movable handle 4 is lost, the finger part can be rotated by gripping the fixed handle 26 and under the restriction of the fixed shaft 27. When gripping the fixed handle 26, the finger part will push the movable plate 30 and compress the spring 29. The reaction force generated by the compression of the spring 29 reduces the impact of the gravity of the lower frame 3 and the upper frame 5 on the finger area.

[0039] like Figure 2 As shown, a second drive motor 23 is fixedly connected to the lower inner wall of the upper frame 5. A second drive rod 22 is provided on the left outer wall of the second drive motor 23. A pusher 7 is screwed onto the circular outer wall of the second drive rod 22 so that the carrier can be pushed onto the loading plate 6 when the pusher 7 moves laterally. A baffle 9 is fixedly connected between the inner walls of the front and rear ends of the upper frame 5. A vertically penetrating limiting hole 8 is provided on the upper outer wall of the baffle 9 near the left side to limit the range of motion of the pusher 7.

[0040] The second drive motor 23 starts, driving the second drive rod 22 to start rotating. As the second drive rod 22 rotates, the push frame 7 begins to move laterally along the axial direction of the second drive rod 22 under the action of the screw drive. When the carrier moves, it will gradually approach the push frame 7. When the push frame 7 contacts the carrier, the second drive motor 23 works again, driving the push frame 7 and the carrier to move to the left through the second drive rod 22 until the carrier is guided onto the loading plate 6. The limiting hole 8 limits and guides the lateral movement range of the push frame 7.

[0041] like Figure 1As shown, the right outer wall of the lower rack 3 is provided with multiple power interfaces 24 to supply power to the processing equipment 2. The inside of the right outer wall of the lower rack 3 is provided with a radiator 18 to draw in cold air for cooling the processing equipment 2. The front and rear outer walls of the lower rack 3 and the upper rack 5 are provided with multiple movable handles 4 to move the lower rack 3 and the upper rack 5 under the action of external force.

[0042] The operator accurately inserts the power cord plug of the processing equipment 2 into the power interface 24 on the right outer wall of the lower rack 3 to supply power to the first drive motor 19, the second drive motor 23 and the processing equipment 2. When the equipment is running, the fan starts and draws in external cold air from the air inlet of the radiator 18. The cold air carries away heat from the heating components of the processing equipment 2 as it flows through them, thus cooling them down. Multiple movable handles 4 are connected to the lower rack 3 and the upper rack 5 by screws. After the lower rack 3 and the upper rack 5 are installed in place, the movable handles 4 are removed and stored. Multiple connecting plates are provided between the lower rack 3 and the upper rack 5 and are connected by screws to restrict the position between the lower rack 3 and the upper rack 5.

[0043] The implementation principle of this embodiment is as follows: The operator starts the feeding program on the human-machine interface 1. The corresponding motor of the first conveyor belt 10 of the upper frame 5 starts, driving the first conveyor belt 10 to run. The carrier loaded with materials begins to move to the left. After moving to the designated position, the material flows to the pick-and-place machine to pick up the material for placement and production. After the material on the carrier is picked up, the empty carrier moves to the upper side of the loading plate 6 under the drive of the first conveyor belt 10. Then the first drive motor 19 starts to work, driving the first drive rod 20 to rotate through the coupling. The first drive rod 20... When rotating counterclockwise, the lifting plate 21 and the carrying plate 6 move downwards. When the carrying plate 6 moves the empty vehicle down to the second conveyor belt 11, the second conveyor belt 11 contacts the empty vehicle and moves the empty vehicle to the right, exiting from the gap between the lower frame 3 and the upper frame 5. The empty vehicle conveyed from the second conveyor belt 11 changes direction under the guidance of the guide plate 12 and slides to the right into the collection bucket 15 for collection. When the number of empty vehicles inside the collection bucket 15 reaches a certain amount, the collection bucket 15 can be taken out for centralized recycling of the empty vehicles.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
