Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit board processing, in particular to an auxiliary fixture for producing flexible circuit boards. Background Art

[0002] A flexible circuit board is a printed circuit board supported by a flexible insulating substrate such as polyimide or polyester film. It has characteristics that rigid circuit boards do not have, such as high reliability, excellent flexibility, and the ability to bend significantly. It also has the characteristics of high wiring density, light weight, thin thickness, and good bendability. The double-sided flexible circuit board printing correction auxiliary fixture is an auxiliary device used for correction and clamping during double-sided printing of flexible circuit boards to better complete double-sided printing. It has been widely used in the field of flexible circuit board printing correction.

[0003] A Chinese authorized patent document, published under the publication number CN211720838U, discloses a flexible circuit board production auxiliary fixture, comprising a base, a through-hole formed in the middle of the top of the base, bidirectional threaded rods disposed in the middle of both sides of the base, and internally threaded sleeves symmetrically sleeved on the outer sides of the bidirectional threaded rods. The utility model facilitates adjustment of the spacing between two sets of support plates through the interaction between the internally threaded sleeves, the through-holes, the support plates, and the bidirectional threaded rods, thereby enabling the clamping of flexible circuit boards of different lengths. This increases the practicality of the fixture, reduces the need to replace different fixtures, and allows the clamped circuit board to be flattened and straightened, thereby improving the success rate of printing. The circuit board can be clamped, and the anti-slip pad effectively prevents damage to the circuit board during clamping. The clamping effect is good and not easy to fall off, resulting in high reliability. The active block can also be flipped, reducing manual flipping that can damage the flexible circuit board, and the operation is simple.

[0004] The above-mentioned existing technology is unable to perform stable fitting detection operations on flexible circuit boards, resulting in poor processing and molding quality of flexible circuit board products. Therefore, it is necessary to develop a new type of flexible circuit board production auxiliary fixture. Utility Model Content
