AI Technical Summary
Existing screen protector application devices do not thoroughly clean the circuit board surface, causing dust to stick to the brush, affecting the application effect. Moreover, the dust is easy to fall off again after cleaning, causing the screen protector to lift or fall off.
A device for applying a film to the surface of a printed circuit board was designed. It uses a robotic arm in conjunction with a control component. The motor drives a threaded rod and a slider to move the brush bristles. Combined with the design of a tapping plate and a spring, the dust is removed by tapping and vibration, preventing it from sticking to the surface of the circuit board again.
It effectively removes dust from the circuit board surface, ensuring a tight and stable adhesion of the film, avoiding problems such as the film lifting or falling off, and improving the film application effect.

Description
Technical Field
[0001] This utility model relates to the field of printed circuit board film application technology, specifically a film application device for printed circuit board surfaces. Background Technology
[0002] Printed circuit boards (PCBs) are indispensable key components in the field of electronics technology. They are three-dimensional structures composed of insulating substrates, conductive patterns (such as copper foil lines), and holes, providing electrical connections and mechanical support for electronic components.
[0003] During the transportation, installation, and use of electronic devices, the surface of circuit boards is easily subjected to mechanical damage such as friction and impact. Applying a protective film can increase the hardness and wear resistance of the circuit board surface, protect the circuit patterns and components, and ensure that the performance of the circuit board is not affected. Therefore, a protective film application device is required.
[0004] Existing film-applying devices typically place the circuit board on a film-applying table and then use a robotic arm to apply the film. However, after processing, dust adheres to the surface of the circuit board, forming a barrier between the board and the film, preventing the film from adhering tightly. This leads to reduced adhesion and problems such as film lifting and peeling during subsequent use. Some film-applying devices with cleaning mechanisms simply use a brush to clean the circuit board, leaving dust and impurities on the brush. This results in dust falling back onto the circuit board when the brush is used again, affecting the subsequent film-applying effect. To address this issue, we propose a film-applying device for printed circuit boards. Utility Model Content
