Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a technical solution:

[0025] Embodiment 1:

[0026] Combination Figure 1 to Figure 2 -3, a circuit board positioning device, comprising a mounting plate 1, with scales 4 fixedly connected to both sides of the top of the mounting plate 1, a moving mechanism 2 is arranged on the top of the mounting plate 1, a positioning mechanism 3 is arranged on the top of the moving mechanism 2, and a limit plate 5 is arranged on the surface of the positioning mechanism 3.

[0027] The moving mechanism 2 includes threaded rods 21, and the threaded rods 21 are all arranged on the top of the mounting plate 1. Both sides of the surfaces of the two threaded rods 21 are rotatably connected with support members 26, and the support members 26 are fixedly connected to the top of the mounting plate 1. A motor 24 is fixedly connected to the right side of one of the threaded rods 21, and the motor 24 is fixedly connected to the top of the mounting plate 1.

[0028] Furthermore, the number of threaded rods 21 is two, and the two threaded rods 21 are arranged in pairs. When the threaded rods 21 rotate, the sliding plate 23 can be driven to move.

[0029] Furthermore, a pulley set 22 is connected to the left side of the surface of the threaded rod 21, and the pulley set 22 is arranged on the left side of the top of the mounting plate 1. Under the linkage effect formed by the pulley set 22, the threaded rods 21 on both sides can be driven to rotate synchronously.

[0030] Furthermore, the surface of the threaded rod 21 is threadedly connected with a sliding plate 23, the top of the sliding plate 23 is fixedly connected with a connecting plate 25, and the limit plate 5 is fixedly connected to the surface of the connecting plate 25. The support rod 35 can be supported by the provided connecting rod.

[0031] Embodiment 2:

[0032] See also Figure 4 On the basis of the first embodiment, the positioning mechanism 3 further includes a placement plate 33, the placement plate 33 is fixedly connected between the two connecting plates 25, a support rod 35 is slidably connected inside the connecting plate 25, and a clamping plate 32 is fixedly connected to one side of the support rod 35. The circuit board can be clamped and fixed by the set clamping plate 32.

[0033] Furthermore, there are two clamping plates 32, which are symmetrically arranged. A spring 34 is sleeved on the surface of the support rod 35, and the spring 34 is arranged between the connecting plate 25 and the clamping member. Under the elastic force of the spring 34, the clamping plates 32 on both sides can be driven to move towards each other.

[0034] Furthermore, a support frame 31 is fixedly connected to the side of the support rod 35 away from the clamping plate 32.

At this time, the moving distance of the circuit board can be judged by observing the limit plate 5 and the scale 4. When the circuit board is processed, there is no need to manually adjust its position, which improves the processing efficiency of the circuit board.
