[0031] The clamping assembly includes a box body 52, four rotating rods 53 and a buckle plate 531 fixed at the lower end of the rotating rod 53, the rotating rod 53 is rotatably connected to the box body 52 and is parallel to the vertical moving direction of the moving seat 50, a cavity is opened in the box body 52, the upper end of the rotating rod 53 extends upward into the cavity of the box body 52, and the four rotating rods 53 are fixed with pulleys located in the cavity of the box body 52, and the four pulleys are connected by belts. A third motor is fixed to the upper end surface of the box body 52, and the upper end of one of the rotating rods 53 continues to extend upward through the box body 52 and is fixedly connected to the output shaft of the third motor. The buckle plate 531 has a rectangular cross-section, and the buckle plate 531 is located on both sides of the tray 40 and is lower than the horizontal clamping portion. When the length direction of the buckle plate 531 is parallel to the side of the tray 40, there is a gap between the buckle plate 531 and the horizontal clamping portion of the upper end surface of the tray 40. After the buckle plate 531 rotates ninety degrees, the buckle plate 531 partially overlaps with the horizontal clamping portion at the upper end of the tray 40.

[0032] Two left-right symmetrical guide rails 58 are fixed to the lower end surface of the moving seat 50, and the left guide rail 58 is "L"-shaped. A "T"-shaped extension rod 51 is fixed to the upper end surface of the box body 52. ​​The extension rod 51 is perpendicular to the lateral movement direction of the moving seat 50, and the extension rod 51 slides between the two guide rails 58. A plurality of clamping wheels 59 distributed on the upper and lower sides of the horizontal part of the extension rod 51 are rotatably connected in the guide rail 58.

The rear end of the extension rod 51 is flush with the rear end surface of the box body 52, and the length of the extension rod 51 is greater than twice the length of the tray 40.

[0033] A camera 60 is fixed to the lower end surface of the box body 52. ​​The camera 60 adopts an industrial-grade high-definition camera. A label is affixed to the horizontal clamping portion of the tray 40. The camera 60 can be used to identify the information on the label. A barcode including material information is printed on the camera 60.

[0034] A travel switch 33 is installed at the end of the base 30. When the tray 40 moves to below the clamping assembly, the travel switch 33 is pressed and triggered.

[0035] The first to fifth motors and the camera 60 mentioned above are controlled by an industrial computer. The industrial computer is installed with visual recognition software for decoding barcodes and outputting cargo information, a database system for storing cargo information, shelf locations, sorting records, etc., a central control program for coordinating barcode recognition, whether the travel switch 33 is triggered, and logic control of the first to fifth motors.

[0036] During the actual working process: First, when the material starts to be transported, the industrial computer controls the fifth motor to start, driving the conveying wheel 34 to rotate, thereby moving the conveyor belt 31. At this time, the tray 40 loaded with materials is placed in the groove on the base 30, and the tray 40 is stuck between the two protrusions 32. Then, as the conveyor belt 31 moves, the protrusions 32 push the tray 40 to move toward the rear end of the base 30 until the tray 40 presses the travel switch 33. The industrial computer then determines that the travel switch 33 is triggered and turns off the fifth motor.

[0037] Next, when the tray 40 is clamped, when the travel switch 33 is triggered, the industrial computer runs the visual recognition software, identifies the barcode on the tray 40 through the camera 60, and outputs the decoding information to the industrial computer. Through the decoding information, it is known that the material information in the tray 40 and the layer on which the tray 40 should be placed on the storage rack 1, and then the industrial computer controls the third motor to start, so that the rotating rod 53 rotates ninety degrees, and then turns off the third motor. At this time, after the buckle plate 531 rotates ninety degrees, one end of it is located below the horizontal clamping part on the tray 40.

[0038] Then, during fixed-point sorting, the industrial computer controls the first motor and the second motor respectively. The first motor drives the first screw 56 to rotate, so that the lifting block 23 rises and reverses to descend, and the second motor drives the second screw 57 to rotate, so that the moving seat 50 moves horizontally to the left and moves right when reversed, thereby moving the tray 40 to the front side of the corresponding storage layer, and then the first motor and the second motor are turned off. At this time, the fourth motor is started, which drives the guide rail 58 to rotate, so that the extension rod 51 drives the tray 40 to move backward to the upper side of the shelf 10 of the corresponding storage layer, the fourth motor is turned off, the first motor is restarted, and it is reversed, thereby driving the tray 40 to descend, until the tray 40 is placed on the shelf 10, the clamping assembly continues to move downward for a distance, so that the pinch plate 531 is away from the horizontal clamping part on the tray 40, the first motor is turned off, the third motor is restarted, and the pinch plate 531 is driven to rotate ninety degrees, and then the third motor is turned off.

[0039] During resetting, after the tray 40 is placed, the clamping assembly is driven to reset above the rear end of the base 30 under the control of the industrial computer.

[0040] During the fixed-point sorting process, when the clamping assembly clamps the tray 40 away from the base 30, the tray 40 is disengaged from the travel switch 33, and the travel switch 33 is reset, so that the industrial computer re-controls the fifth motor to restart, driving the subsequent tray 40 to move toward the rear end of the base 30, until the subsequent tray 40 presses the travel switch 33 again, and the fifth motor is turned off again.

[0041] During the fixed-point sorting process, when the sorting mechanism 2 places the tray 40 on its corresponding storage layer, it will be placed preferentially at the leftmost end of the storage layer. The industrial computer records its running trajectory and thus records its placement position. If a tray 40 of the same storage layer needs to be placed later, the industrial computer will avoid the position where the tray 40 has been placed originally, and place the subsequent tray 40 on its right side, and the interval between the two trays 40 is greater than the length of the buckle plate 531.

[0042] Reference Figure 8 In the present application, two material racks 200 are arranged on the side of one end of the conveyor belt 31 away from the rack 1; a palletizer 100 is arranged between the two material racks 200; wherein the palletizer 100 is an existing product that can be directly obtained on the market, and the present application realizes automatic transfer of materials located on the conveyor belt 31 to the material racks 200 located on both sides of the palletizer 100 through the palletizer 100; through the compilation of the program, the pallets 40 loaded with different materials can be moved to different material racks 200, thereby improving the production efficiency.

[0043] It will be clear to those skilled in the art that various modifications to the above embodiments may be made without departing from the overall spirit and concept of the present invention.
