The frame body 21 is a square frame with two sides passing through it, and the two sides passing through it correspond to the direction of conveying on the first conveyor belt 14. The movable plate 23 is arranged in the frame body 21 parallel to the side wall of the frame body 21. The bottom of the movable plate 23 is provided with a screw hole. The bottom side of the frame body 21 is penetrated by a screw rod 24 that engages with the screw hole. The two ends of the screw rod 24 are rotatably connected to the frame body 21, and the screw rod 2 4 extends to the outside of the frame 21, and a driving member 50 is detachably connected to the end of the screw rod 24 on the conveying frame; the carrying plate 22 is arranged on one side of the movable plate 23 and on the inner side wall of the frame 21 opposite thereto, and for the convenience of disassembly and replacement, the carrying plate 22 can be respectively connected to the movable plate 23 and the inner side wall of the frame 21 by bolt connection, and a plurality of carrying edges 25 are arranged on the carrying plate 22 at intervals, and both sides of the PCB board can be supported by the carrying edges 25; the lifting frame is arranged on one side of the conveying frame, and includes a lifting mechanism 31, a lifting plate 32 and a second conveyor belt. The lifting mechanism 31 can select any device that can realize the lifting plate 32 in the existing technology, and the second conveyor belt is arranged on the lifting plate 32, and the lifting mechanism 31 is connected to the lifting plate 32; the first cylinder 40 is arranged at the bottom of the top frame body 11, and a third conveyor belt 60 is arranged on the side of the lifting frame facing away from the conveying frame, and the height is aligned with the first cylinder 40, which is used to convey the PCB board to the next process.
[0029] The working principle of the above technical solution is as follows:
[0030] The upper plate frame 20 rotates the screw rod 24 through the driving member 50, moves the movable plate 23 to adjust the distance between the two carrying plates 22, and then moves to the equipment for loading PCB boards in the previous process, so as to facilitate the loading of PCB boards of corresponding specifications. After loading, the initial position of the upper plate frame 20 is on the bottom frame body 12, and is transported to the lifting frame by the first conveyor belt 14 on the bottom frame body 12, and moves to the top of the lifting plate 32 in coordination with the second conveyor belt on the lifting plate 32. The lifting plate 32 is lifted by the lifting mechanism 31, and the PCB board at the highest position in the frame body 21 is aligned with the first cylinder 40, and the first cylinder 40 is extended. The PCB board is pushed onto the third conveyor belt 60 and conveyed to the next process. Thereafter, each time the lifting mechanism 31 is lifted, the PCB board on the next load-bearing edge 25 is aligned with the first cylinder 40. The above operation is repeated until all the PCB boards on the frame body 21 are pushed onto the third conveyor belt 60, and then the lifting plate 32 is lifted to be aligned with the top surface of the top frame body 11, and the upper plate frame 20 is moved toward the fixed frame body through the second conveyor belt. The first conveyor belt 14 of the top frame body 11 moves the upper plate frame 20. When the distance between the two load-bearing plates 22 needs to be adjusted, the driving member 50 is aligned and the screw rod 24 is connected, and the initial operation can be repeated.
[0031] In another embodiment, if Figure 2 and Figure 4 As shown, the driving member 50 includes a mounting seat 51, a connecting seat 52, a second cylinder 53, a motor 54 and a connecting tube 55. The mounting seat 51 is arranged on one side of the top frame 11 parallel to the first conveyor belt 14, the second cylinder 53 is arranged on the mounting seat 51 perpendicular to the conveying direction of the first conveyor belt 14, the connecting seat 52 is arranged at the end of the second cylinder 53, the motor 54 is arranged on the connecting seat 52, and the axial direction of the motor 54 is parallel to the second cylinder 53, the connecting tube 55 is arranged on the shaft of the motor 54, the end of the screw rod 24 located on the outside of the frame body 21 is provided with a connecting head 26, the inner side of the connecting tube 55 is provided with a clamping block 56, and the outer side of the connecting head 26 is provided with a clamping groove 27, the curvature of the clamping groove 27 is greater than that of the clamping block 56, and the curvature of the clamping groove 27 can be more than twice the curvature of the clamping block 56.
