[0002] In the production process of automatic production lines, in order to meet the high-speed and efficient operation of the production lines, it is often necessary to replace the original manual loading and unloading with automatic and mechanized loading and unloading. In addition, for the loading and unloading of many parts, the parts are often placed on a tray. In the process of loading and unloading, the whole tray is loaded, and then the robot grabs the parts.

The side of the positioning plate 205 away from the tray pushing mechanism 400 is fixedly connected to the vertical rod 201.

[0033] The tray moving mechanism 300 is disposed on the top of the base 101 and connected to the base 101;

[0034] The tray moving mechanism 300 includes a pair of mounting blocks 301 fixedly connected to the upper surface of the base 101 by bolts, a driving motor 302 fixedly connected to one side of one of the mounting blocks 301 away from the other mounting block 301 by bolts, a screw rod 303 rotatably installed between the pair of mounting blocks 301 through a bearing, and a guide slide rod 304 fixedly connected between the pair of mounting blocks 301, a moving block 305 is threadedly connected to the screw rod 303, and the guide slide rod 304 slides through the moving block 305. By setting the guide slide rod 304, the movement of the moving block 305 can be guided, the output end of the driving motor 302 is fixedly connected to one end of the screw rod 303, the top of the moving block 305 is fixedly connected to the second hydraulic cylinder 306 by bolts, and the piston end of the second hydraulic cylinder 306 is fixedly connected to the bearing plate 307 by bolts, the bearing plate 307 is located below the fully loaded tray 202, and is arranged corresponding to the fully loaded tray 202, and the second hydraulic cylinder 306 movably passes through the moving groove 104;

[0038] In summary, when in use, when conveying the fully loaded material tray 202, first the second hydraulic cylinder 306 drives the carrying plate 307 to move upward and be supported on the bottom of the fully loaded material tray 202, and then the first hydraulic cylinder 204-1 drives the supporting rod 204-2 to retreat and move away from the fully loaded material tray 202, and then the second hydraulic cylinder 306 drives the stacked fully loaded material trays 202 to collectively move downward to the height of a fully loaded material tray 202, and then the first hydraulic cylinder 204-1 drives the supporting rod 204-2 to reset and be supported under the second to last fully loaded material tray 202, and then the second hydraulic cylinder 306 continues to drive the carrying plate 307 to move downward, and the carrying plate 307 drives the lowest fully loaded material tray 202 to move downward, when the bottom of the carrying plate 307 contacts the pressure sensor 206 on the positioning plate 205 and generates pressure, the driving motor 302 runs, the second hydraulic cylinder 306 stops running, and the driving motor 302 drives the screw rod 303 to rotate when it runs, and the moving block 305 moves downward.

The operation is simple. The stop position of the lateral movement of the fully loaded material tray 202 corresponds to the push rod 403. When the fully loaded material tray 202 becomes an empty material tray, the third hydraulic cylinder 402 runs, and the piston end of the third hydraulic cylinder 402 drives the push rod 403 forward, and the push rod 403 pushes the empty material tray to move in the direction of the material tray recovery conveyor 500 until the empty material tray is pushed onto the conveyor belt of the material tray recovery conveyor 500 (the above process is controlled by the PLC controller. Since the use principle and connection method of the PLC controller belong to the prior art, they will not be described in detail here). The empty material tray can be automatically transported to the designated location through the material tray recovery conveyor 500, and workers do not need to manually pick up and carry the empty material tray for a long distance. The labor intensity of workers is small and the recovery efficiency is high. In addition, by using the positioning plate 205 in conjunction with the pressure sensor 206, etc., the recovery height of the fully loaded tray 202 can be quickly determined, thereby improving the recovery efficiency of the empty tray.

[0039] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
