[0027] Furthermore, the number of the clamping members 26 is two, and the two clamping members 26 are symmetrically arranged on both sides of the top of the support frame 1. The circuit board can be clamped and fixed by the arranged clamping members 26.

[0028] Furthermore, fixed frames 23 are fixedly connected on both sides of the support frame 1, and threaded rods 25 are rotatably connected inside the two fixed frames 23. The surfaces of the two threaded rods 25 are transmission-connected with pulley groups, which are arranged on the right side of the support frame 1. During the rotation of the threaded rods 25, the mounting frame 37 can be driven to move.

[0029] Furthermore, the motor 21 is fixedly connected to the left side of the threaded rod 25, and a positioning plate 22 is fixedly connected to the surface of the motor 21. The positioning plate 22 is fixedly connected to the surface of the support frame 1. The motor 21 can be supported and fixed by the positioning plate 22.

[0030] Example 2: See Figure 4-5 On the basis of Example 1, the tin coating mechanism 3 further includes a mounting frame 37, the mounting frame 37 is threadedly connected to the surface of the threaded rod 25, the first cylinder 31 is fixedly connected to both sides of the top of the mounting frame 37, the top of the first cylinder 31 is fixedly connected to a fixing plate 32, the right side of the fixing plate 32 is fixedly connected to a connecting plate 38, the first cylinder 31 drives the fixing plate 32 to move downward, at this time the nozzle 302 can be closer to the circuit board.

By setting a movable nozzle 302, tinning can be performed on other positions of the circuit board, thereby improving the practicality of the device.

[0035] When the circuit board needs to be tinned, the first cylinder 31 is started, and the first cylinder 31 drives the fixed plate 32 to move downward. At this time, the nozzle 302 can be closer to the circuit board. Then, the second cylinder 36 is started. Under the action of the second cylinder 36, the baffle 301 can be driven to move downward, and the paint inside the placement box 34 is squeezed through the baffle 301. At this time, the paint is sprayed out from the nozzle 302, thereby achieving the purpose of automatic tinning of the circuit board. Electric instead of manual, improves the efficiency of tinning of the circuit board.
