The first receiving groove 36 is used to place the product to be processed, and the second receiving grooves 37 and the notch 38 are used to accommodate the support plate 43. A housing 3 is provided on both sides of the tray 35, and the housing 3 is fixedly connected to the frame 1. A transmission belt 31 is installed in the housing 3. A motor 33 is fixedly connected to the frame 1. The output end of the motor 33 is fixedly connected to the first rotating shaft 34. The first rotating shaft 34 is rotatably connected to the housing 3, and the transmission belt 31 is driven by the first rotating shaft 34. Multiple connecting seats 32 are evenly distributed on both outer walls of the tray 35, and the connecting seats 32 are fixedly connected to the transmission belt 31. The motor 33 is started, and the motor 33 drives the transmission belt 31 through the first rotating shaft 34. The transmission belt 31 drives the tray 35 through the connecting seats 32, realizing the movement of the tray 35 between the processing position and the loading position. The housing 3 is used to install the transmission belt 31. A welding machine 5 is set at the top of the tray 35, and a conveyor 6 is set at the bottom of the tray 35. Both the welding machine 5 and the conveyor 6 are fixedly connected to the frame 1. The welding machine 5 is used to weld products, and the conveyor 6 is used to send products out of the equipment.A mounting plate 2 is fixedly connected to the frame 1. A first cylinder 21 is fixedly connected to the mounting plate 2. A mounting frame 22 is fixedly connected to the output end of the first cylinder 21. Multiple suction cups 24 are fixedly connected to the mounting frame 22. The first cylinder 21 is used to drive the mounting frame 22 to rise and fall, and the suction cups 24 are used to pick up the products to be processed. A guide rod 23 is fixedly connected to the mounting frame 22 and is slidably connected to the mounting plate 2. The guide rod 23 is used to guide the rising and falling of the mounting frame 22. A material rack 7 is provided on one side of the conveyor 6 and is located at the bottom of the suction cups 24. The material rack 7 is used to place the products to be processed.

[0021] Working Principle: When using this utility model, firstly, the first cylinder 21 on the mounting plate 2 extends. Under the guidance of the guide rod 23, the first cylinder 21 drives the mounting frame 22 to move vertically downward. The suction cup 24 on the mounting frame 22 moves downward accordingly, using the suction cup 24 to pick up the product to be processed on the material rack 7. Then, the first cylinder 21 retracts, driving the suction cup 24 to move upward and reset. At this time, the motor 33 is started. The motor 33 drives the transmission belt 31 via the first rotating shaft 34. The transmission belt 31 drives the tray 35 via the connecting seat 32, moving the tray 35 from the processing position to the loading position. Then, the first cylinder 21 extends, placing the product to be processed into the first receiving groove 36 of the tray 35, supported by the support plate 43. Then, the suction cup 24 stops sucking air, releasing the product to be processed. The first cylinder 21 retracts, driving the suction cup 24 to move upward and reset. At this time, the motor 33 reverses, moving the tray 35 from the loading position to the processing position. The welding machine 5 is used to weld the product to be processed. After welding, the second cylinder 45 is retracted. The second cylinder 45 drives the swing arm 47 through the second mounting base 46. The swing arm 47 drives the connecting shaft 48. The connecting shaft 48 drives one of the second rotating shafts 41 to rotate. Under the transmission action of the bevel gear 42, all four second rotating shafts 41 rotate. The support plate 43 on the second rotating shaft 41 rotates accordingly. The product loses its support and falls onto the conveyor 6. It is transported out of the equipment by the conveyor 6. Then the second cylinder 45 extends and drives the support plate 43 to reset. In this way, the welding of one product is completed. The housing 3 on the frame 1 is used to install the transmission belt 31. The transmission belt 31 and the first rotating shaft 34 are connected by a pulley. This is existing technology and will not be described in detail. The second receiving groove 37 and the notch 38 are used to receive the support plate 43. The first mounting base 44 is used to install the second cylinder 45.
