Description

Technical Field

The development of PCB technology has made electronic devices more compact and efficient, becoming one of the key technologies indispensable in the development of modern science and technology. At the same time, it is necessary to spray both sides of the PCB board.

[0003] In a spraying device for a PCB board with the authorization announcement number "CN218078519U", the PCB board is sprayed by a spraying component. The spraying plate can limit the spraying position of the spraying liquid, preventing spraying on the PCB circuit. And during the spraying process of the utility model, the PCB board can be fixed by a pressing component to prevent vibration of the machine and the movement of the PCB board resulting in defective products. However, the device fixes the PCB board through the pressing component, resulting in a large area of the pressing area of the PCB board being blocked, causing a part of the area of the PCB board not to be sprayed normally, reducing the spraying quality of the device. The device can only spray one side of the PCB board. When it is necessary to spray the other side, the operator needs to disassemble and flip it, increasing the workload of the operator and reducing the working efficiency of the device.

By connecting the external power supply of the hydraulic cylinder 12, start the telescopic end of the hydraulic cylinder 12 to extend or shorten to drive the spraying assembly 13 to move vertically, and adjust the spraying position of the PCB board. When one side of the PCB board is sprayed, use the auxiliary turning and spraying device to turn over the PCB board for spraying, and complete the auxiliary clamping process for spraying both sides of the PCB board.

[0031] Auxiliary turning and spraying process for spraying both sides of the PCB board:
