[0025] like Figure 1 、 3As shown in the figure, the conveying mechanism 2 includes a motor 201. A threaded rod 202 is fixedly connected to the power output end of the motor 201. One end of the threaded rod 202 is rotatably connected to a first vertical plate 203. A moving plate 204 is threadedly connected to the outer wall of the threaded rod 202. The bottom of the moving plate 204 is slidably connected to the outer wall of the workbench 1. A first sliding rod 205 is slidably connected to the inner wall of the moving plate 204. Both ends of the first sliding rod 205 are fixedly connected to a second vertical plate 206. The end of the second vertical plate 206 is fixedly connected above the workbench 1. The bottom of the motor 201 is connected above the workbench 1. By driving the threaded rod 202 to rotate through the motor 201, the threaded rod 202 drives the moving plate 204 to move. The moving plate 204 restricts the moving direction of the moving plate 204 by moving on the first sliding rod 205 in the first chute 101. The moving plate 204 moves to convey the circuit board, avoiding manual transmission and further improving work efficiency.

[0026] As Figure 1 , 3 shown, the bottom of the box body 301 is fixedly connected above the moving plate 204, and the bottom of the clamping plate 305 is slidably connected to the outer wall of the moving plate 204.

[0027] As Figure 1 shown, a pressing mechanism 4 is installed above the workbench 1. The pressing mechanism 4 includes a U-shaped plate 401. An electric push rod 402 is fixedly connected to one side of the U-shaped plate 401. A pressing plate 403 is fixedly connected to the end of the electric push rod 402. Both ends of the pressing plate 403 are slidably connected to the outer wall of the U-shaped plate 401. The end of the U-shaped plate 401 is fixedly connected above the workbench 1. By pushing the pressing plate 403 to move through the electric push rod 402, the pressing plate 403 presses the circuit board by moving in the fourth chute 4011.

[0028] As Figure 1 , 3 shown, a rotating groove adapted to the threaded rod 202 is formed on the outer wall of the first vertical plate 203, and one end of the threaded rod 202 extends into the rotating groove. A first chute 101 adapted to the moving plate 204 is formed on the outer wall of the workbench 1, and the bottom of the moving plate 204 extends into the first chute 101. The rotation of the threaded rod 202 on the first vertical plate 203 facilitates the movement of the moving plate 204 on the workbench 1.

[0029] As Figure 2 shown, a third chute 3011 adapted to the sliding plate 303 is formed on the inner wall of the box body 301, and both ends of the sliding plate 303 extend into the third chute 3011, facilitating the movement of the sliding plate 303 on the box body 301.

[0030] As Figure 1As shown, a fourth chute 4011 adapted to the pressure plate 403 is provided on the outer wall of the U-shaped plate 401, and both sides of the pressure plate 403 extend into the fourth chute 4011, facilitating the movement of the pressure plate 403 on the U-shaped plate 401.

[0031] As Figure 1 , 2 shown, a second chute 2041 adapted to the clamping plate 305 is provided on the outer wall of the moving plate 204, and the end of the moving plate 204 extends into the second chute 2041, facilitating the movement of the clamping plate 305 on the moving plate 204.

[0032] In this embodiment, first, all parts are installed. When pressing the circuit board, first, the clamping plate 305 is pushed to move on the second chute 2041. The movement of the clamping plate 305 drives the movement of the moving rod 304. The moving rod 304 pushes the sliding plate 303 to move. The sliding plate 303 compresses the spring 306 by moving on the third chute 3011 through the second sliding rod 302, thereby adjusting the distance between the clamping plates 305 to adapt to clamping and fixing circuit boards of different sizes, avoiding offset during the pressing process, and improving the processing efficiency of the circuit board. After the circuit board is clamped and fixed, then the motor 201 drives the threaded rod 202 to rotate. The threaded rod 202 drives the moving plate 204 to move. The moving plate 204 restricts the moving direction of the moving plate 204 by moving on the first chute 101 through the first sliding rod 205. The moving plate 204 moves to convey the circuit board, avoiding manual transmission and further improving the working efficiency. When the moving plate 204 conveys the circuit board directly below the pressure plate 403, then the electric push rod 402 is used to push the pressure plate 403 to move. The pressure plate 403 presses the circuit board by moving on the fourth chute 4011.
