Problems solved by technology

However, in the actual operation process, the flexible circuit board is deflected by the vibration generated by the operation of the transmission mechanism, so that the circuit board cannot be completely covered by the protective film, reducing the coating effect
At the same time, the dust on the surface of the circuit board will affect the adhesion between the protective film and it, which is not conducive to the lamination operation, increases the scrap rate of production, and causes waste and unnecessary losses.

Abstract

The invention relates to the technical field of flexible circuit boards, and discloses a protective film coating device for flexible circuit boards. Avoid the flexible circuit board being shifted by vibration while being transferred with the transmission belt, and ensure that the flexible circuit board can be effectively coated. While fixing the flexible circuit board, it triggers the cleaning and film covering operations to increase the linkage between the structures, which is convenient to operate and has a high degree of automation. , using the pressure to automatically clean and collect the dust on the surface of the flexible circuit board, avoiding the existence of dust, reducing the adhesion between the circuit board and the protective film, and enhancing the coating effect. After cleaning, it will automatically spray air on the protective film to make the protective film Adhesive to flexible circuit boards to achieve lamination.

Description

technical field [0001] The invention relates to the technical field of flexible circuit boards, in particular to a protective film coating device for flexible circuit boards. Background technique [0002] Flexible circuit boards are also known as flexible circuit boards and flexible circuit boards. They are favored for their light weight, thin thickness, and free bending and folding. During the processing of the flexible circuit board, it needs to be covered with a film to insulate the circuit from dust and moisture. At present, when laminating, the flexible circuit board is transferred to the lower part of the laminating mechanism by the conveying mechanism, and the protective film is attached to the flexible circuit board by using the flow of gas. However, in the actual operation process, the flexible circuit board is deflected by the vibration generated by the operation of the transmission mechanism, so that the circuit board cannot be completely covered by the protectiv...
