The mounting seat 30 is fixed on the top surface of the workbench 1, and eight bases 31 are respectively fixed on the bottom surfaces of the left and right ends of the dispensing machine 4, the printing machine 5, the electric welding machine 6 and the testing machine 7. A slide groove 301 is opened in the center of the top surface of the mounting seat 30. The mounting seat 30 is rotatably connected with a bidirectional screw rod 302 in the slide groove 301. The thread directions of the two ends of the bidirectional screw rod 302 are opposite. Both ends of the bidirectional screw rod 302 are threadedly connected with a clamping plate 303. When the bidirectional screw rod 302 rotates, the two clamping plates 303 are close to or away from each other, which is convenient for disassembly and combination of different modules and more practical.

[0032] In this embodiment, the conveying mechanism 2 includes two vertical plates 20 fixed side by side at the center of the top surface of the workbench 1. The front and rear ends of the two vertical plates 20 are rotatably connected with rollers 21. The two rollers 21 are connected by a conveyor belt 22. The material can be fixed on the conveyor belt 22 for transportation.

[0033] Specifically, the conveying mechanism 2 further includes a control motor 23 fixed on one of the vertical plates 20 , the output shaft of the control motor 23 is coaxially connected to one of the rollers 21 , and the control motor 23 serves as a power source to control the operation of the roller 21 .

[0034] Specifically, the four corners of the bottom surface of the base 31 are provided with sockets 310 , and the top surface of the mounting seat 30 is provided with plug posts 300 corresponding to the positions of the sockets 310 and matching in size, so as to facilitate alignment of the mounting seat 30 and the base 31 .

[0035] Furthermore, docking posts 304 are fixed to the top of the opposite surfaces of the two clamps 303, and docking holes 311 corresponding to the positions of the docking posts 304 and having sizes matching the docking posts 304 are opened on the left and right sides of the base 31, so that the clamps 303 and the base 31 are in closer contact.

[0036] In addition, one end of the bidirectional screw rod 302 away from the conveying mechanism 2 extends to the outside of the mounting seat 30 and is coaxially connected to a hand wheel 305, which is used to control the movement of the two clamping plates 303, so as to facilitate the rotation of the bidirectional screw rod 302 from the outside.
