[0002] A PCB circuit board is a device that mounts various electronic components on a board. The PCB circuit board has the characteristics of highly concentrated electronic components, small size, and small surface area, and can implement more complex circuits. When manufacturing a PCB circuit board, glue needs to be sprayed on the surface of the PCB circuit board through a coating spraying equipment. After the glue solidifies, a hard protective film will be formed on the surface of the PCB circuit board. This protective film is not only hard but also waterproof and scratch-resistant, effectively protecting the PCB circuit board. However, traditional coating spraying equipment needs to fix the PCB circuit board before spraying it. However, due to different models of PCB circuit boards, the traditional coating spraying equipment cannot be matched and fixed, resulting in poor adaptability. In addition, when the traditional coating spraying equipment sprays a double-sided PCB circuit board, it needs to first fix and spray one side, then disassemble and fix the other side and then spray the other side. This method requires repeated disassembly and fixation of the PCB circuit board, which is rather troublesome. Therefore, a spraying equipment for glue coating on the surface of a PCB circuit board is proposed. Content of the Utility Model

A second bearing 8 is fixedly connected inside the vertical plate 7. The inner ring of the second bearing 8 is fixedly connected with a first connecting rod 9. The other end of the first connecting rod 9 is fixedly connected with a clamping plate 10. By setting the double-shaft motor 3, the threaded rod 4, the threaded block 6, the vertical plate 7, and the clamping plate 10, by starting the double-shaft motor 3 to drive the threaded rod 4, the threaded block 6 moves towards the central direction, thereby driving the vertical plate 7 to move towards the central direction, reducing the distance between the left and right clamping plates 10 until the left and right clamping plates 10 clamp the PCB circuit board. Through this device, the fixing of PCB circuit boards of different models is realized, which has practicability.

[0025] The inner ring of the second bearing 8 on the left is fixedly connected with a first transmission rod 11.

The output shaft of the transmission motor 15 is fixedly connected with a second transmission rod 14. The other end of the second transmission rod 14 is fixedly connected with a second gear 13. By setting the transmission motor 15, the second transmission rod 14, the second gear 13, the first gear 12, and the first transmission rod 11, by starting the transmission motor 15 to drive the second transmission rod 14, the second gear 13 drives the first gear 12 to rotate, so that the first transmission rod 11 drives the first connecting rod 9 to rotate, thereby making the first connecting rod 9 drive the clamping plate 10 to rotate around the second bearing 8, causing the PCB circuit board clamped by the clamping plate 10 to flip, so that the reverse side of the PCB circuit board faces the spraying mechanism 21. At this time, the spraying mechanism 21 can be started to spray the reverse side of the PCB circuit board. Through this device, the double-sided spraying of the PCB circuit board is realized, avoiding the need to repeatedly fix and disassemble the PCB circuit board when spraying the double-sided PCB circuit board in the traditional way, improving the flexibility of the device, and being convenient and fast.
