A covering film attaching device for the production of flexible circuit boards

Abstract

The invention relates to the technical field of a circuit board processing accessory device, in particular to a covering film attaching device used for the production of a flexible circuit board, which has high automation degree, does not need to attach the film manually, and improves the working efficiency. And the adhered film can be compacted to improve the adhesion effect of the film; At the same time, the attached film can be cut to reduce the burden of subsequent processing and improve the reliability of use; Including console, Left support plate, right support plate, top plate, First motor, Second motor, The first lead screw, the second lead screw, the slider, the first ball bearing, the front stop lever, the rear gear lever, the left fixing plate, the right fixing plate, the secondball bearing, the electro-hydraulic cylinder, the hydraulic lever and the pressure roller are provided with a fixing groove at the top end of the mounting table, and further comprising a first cylinder, a compaction box, a pressing plate, a first piston rod, a spring, a limiting plate, a second cylinder, a second piston, a mounting plate, a knife plate and a cutter.

[0002] As we all know, the cover film attachment device used in the production of flexible circuit boards is an auxiliary device for attaching a layer of film on the surface of flexible circuit boards to protect flexible circuit boards. It is used in the field of flexible circuit board processing. It has been widely used; the existing cover film attaching device for flexible circuit board production includes an operation table, the top of the operation table is provided with a fixed plate, and the top of the fixed plate is provided with a mounting groove; the existing When using the cover film attaching device for the production of flexible circuit boards, the flexible circuit board is placed in the installation groove on the top of the fixed plate, and then the film is manually attached to the surface of the flexible circuit board; the existing one is used for flexible circuit boards During the use of the produced cover film attachment device, it was found that the efficiency of manual attachment was low and could not meet mass production; and the film could not be compacted, resulting in poor skin attachment effect; at the same time, the attached film could not be Clipping, which increases the burden on subsequent processing, resulting in lower reliability
