[0002] The performance of circuit boards can be affected by many external or environmental factors, such as moisture, extreme temperature, salt spray, and chemicals. The protective coating is a polymer film coated on the surface of the circuit board to protect the circuit board and its components from corrosion and environmental pollution. By preventing the influence of pollutants and environmental factors, the protective coating can prevent the corrosion of conductors, solder joints, and circuits. In addition, it can also play an insulating role, thereby reducing the influence of thermal and mechanical stresses on the components.

[0038] It can be understood that for the structure of the circuit board surface coating device according to an embodiment of the present invention, the working principles and processes of components such as the conveying component 3, the coating component 4, and the laminating component 5 are all prior art. The specific working process is as follows: The coating is placed in the liquid storage tank and reaches the designated position for spraying under the action of the water pump. After the circuit board is coated, the circuit board is moved to the area of the laminating component 5. The telescopic rod controls the installation box to move downward. A plurality of suspension rods are suspended on the installation box by through holes, and flexible buffer heads are installed at the lower ends of the suspension rods. During the downward movement of the installation box, the buffer heads of each suspension rod gradually come into contact with the surface of the circuit board. Through the movement of the suspension rods relative to the installation box, the bottom plane of the suspension rods fits the plane of the circuit board, pressing down the coating that may be unevenly coated on the surface, making the coating better fit the surface of the circuit board, improving the coating effect, making the coating layer more uniform, and being able to better protect the circuit board.
