Technical Field
[0001] This utility model relates to the field of flexible circuit board technology, specifically to a flexible circuit board cover film bonding fixture. Background Technology
[0002] With the development of electronic products, industry competition is becoming increasingly fierce. Products that are both high-quality and inexpensive are becoming more competitive, making low cost a crucial factor in competitiveness. Therefore, it is imperative to reduce the cost of each component. For flexible circuit boards (PCBs), overall cost reduction can be achieved by lowering the cost of production tooling and fixtures. There is an intention to develop a simplified tool for cover film lamination processes to replace traditional fixtures, thereby achieving cost reduction and efficiency improvement.
[0003] In the process of covering flexible circuit boards, existing glass fiber board fixtures generate dust during processing, have low precision, are heavy, and are not conducive to operation, which can easily increase processing costs. Therefore, this application proposes a flexible circuit board cover film bonding fixture. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a flexible circuit board cover film bonding fixture, which solves the problems of existing fiberglass board fixtures generating dust during processing, having low precision, being heavy, and being inconvenient to operate, thus easily increasing processing costs.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a flexible circuit board cover film bonding fixture, including a fixture body, the fixture body being fixedly installed on a laminating machine, a PET adsorption film being pasted on the outer side of the fixture body, a first adsorption hole being opened on the outer side of the fixture body, and a through second adsorption hole being opened on the PET adsorption film, wherein the first adsorption hole and the second adsorption hole are adapted to each other.
[0006] A connecting block is fixedly installed at the bottom of the fixture body. The inside of the connecting block is connected to the first adsorption hole, and a connecting pipe is fixedly connected to the outside of the connecting block. The connecting pipe is connected to the coating machine.
[0007] Preferably, the bottom end of the connecting pipe has a pipe joint.
[0008] Preferably, a plurality of limiting blocks are fixedly installed on the outer side of the main body of the fixture.
[0009] Preferably, the PET adsorption membrane has multiple through-holes, and multiple limiting blocks are respectively inserted into the multiple limiting holes.
[0010] Preferably, the PET adsorption membrane has a through positioning hole.
[0011] Preferably, a fixing frame is fixedly installed on the back of the fixture body.
[0012] Preferably, a mounting block is fixed to the top of the fixing frame.

[0014] This utility model discloses a flexible circuit board cover film bonding fixture, which has the following beneficial effects:
[0015] This flexible circuit board cover film bonding fixture works by placing the cut cover film onto the PET adsorption film of the laminating machine, ensuring accurate positioning, then placing the circuit board onto the cover film, and adjusting the fixture to align the circuit board perfectly with the cover film. The vacuum pump is then activated, and the PET adsorption film adheres to both the cover film and the circuit board under vacuum. This creates a tight bond between the cover film and the circuit board. The PET adsorption film, with a thickness of 0.125mm, is thinner than existing fiberglass board fixtures and less prone to dust accumulation, effectively eliminating dust and debris generated during processing and reducing foreign matter during cover film bonding.
[0016] The diameters of the first and second adsorption holes are set to 0.05 mm, which is smaller and more precise than the diameter of existing fiberglass board fixtures, thus enabling a more effective adsorption effect on circuit boards and cover films. Attached Figure Description

[0036] It should be emphasized that the thickness of the PET adsorption membrane 2 is set to 0.125 mm.
[0037] It should be emphasized that the diameter of the first adsorption pore 11 and the second adsorption pore 21 is set to 0.05 mm.
[0038] During use, the cut cover film is placed on the PET adsorption film 2 of the laminating machine, ensuring accurate positioning. Then, the circuit board is placed on the cover film, and the fixture position is adjusted to ensure complete alignment between the circuit board and the cover film. The vacuum pump is started, and the PET adsorption film 2 performs vacuum adsorption on the cover film and circuit board. Under vacuum, a tight bond is formed between the cover film and the circuit board. The PET adsorption film 2, with a thickness of 0.125mm, is thinner and less prone to dust accumulation compared to existing fiberglass board fixtures, effectively eliminating dust and debris generated during processing and reducing foreign matter during cover film lamination.
