Description

Technical Field

[0001] The utility model belongs to the technical field of FPC adhesive tapes, and in particular relates to a continuous FPC adhesive tape and an alignment fixture thereof. Background Art

[0002] Flexible Printed Circuit (FPC) is a highly reliable and flexible printed circuit board made of polyimide or polyester film. It is favored for its excellent properties such as light weight, thin thickness, free bending and folding. In modern industrial production, FPC is widely used in various electronic devices, such as smart phones, wearable devices, etc.

[0003] In order to ensure the stability and functionality of FPC, it is usually necessary to paste tape on its surface to fix, insulate or protect it. At present, the existing FPC tape can only be pasted one by one when pasting. This operation method requires the operator to accurately align the position of each FPC and complete the pasting work carefully. Although this method can ensure the accuracy of tape pasting, due to its cumbersome operation process and low efficiency, it can no longer meet the needs of modern industrial production for efficiency and automation.

[0004] Through the above analysis, the problems and defects of the existing technology are: the existing FPC tape can only be pasted one by one during application, the operation process is cumbersome and inefficient, and it can no longer meet the needs of modern industrial production for high efficiency and automation. Utility Model Content

[0005] In order to overcome the problems existing in the related art, the utility model provides a continuous FPC adhesive tape and an alignment fixture thereof.

[0006] The technical solution of the utility model is as follows: a continuous FPC adhesive tape is provided with an adhesive tape layer; the adhesive tape layer includes a plurality of adhesive tape strips arranged at equal intervals, and a release paper is pasted on one side of the bonding surface of the adhesive tape layer;

[0007] A plurality of blue release films corresponding to the adhesive tape strips are attached to the back of the adhesive tape layer, a micro-adhesive film is attached to the other side of the blue release film, and the plurality of blue release films are connected by the micro-adhesive film.

[0008] In one embodiment, one end of the adhesive tape is integrally connected with a non-adhesive tear strip.

[0009] In one embodiment, a plurality of positioning holes are opened in the middle of the micro-mucosa.

[0010] In one embodiment, a plurality of rows of avoidance holes are provided in the middle of the micro-mucosal membrane, and the plurality of rows of avoidance holes respectively correspond to the interval positions of the plurality of adhesive tape strips.

[0011] Another object of the present invention is to provide an alignment jig for processing continuous FPC adhesive tape. The alignment jig is provided with a substrate, and a plurality of rows of countersunk holes corresponding to the adhesive tape strips are provided on the surface of the substrate. The countersunk holes include deep countersunk holes and shallow countersunk holes arranged in an staggered manner.

[0012] In one embodiment, a plurality of positioning posts corresponding to the positioning holes of the micro-mucosa are fixed on the surface of the substrate.

[0013] In one embodiment, the substrate is a wooden board with a thickness of more than 10 mm.

[0014] In combination with all the above technical solutions, the beneficial effects of the utility model are as follows: the continuous FPC adhesive tape provided by the utility model forms a continuous structure with multiple adhesive tape strips by adding a micro-adhesive film, which is convenient for applying multiple adhesive tape strips at the same time, can effectively improve the bonding efficiency and save labor costs.

[0015] The utility model can facilitate the taking operation of the adhesive strip through the adhesive-free tear strip; the positioning hole in the middle of the micro-adhesive film can facilitate the fitting and positioning of the adhesive strip; and the micro-adhesive film and the nickel sheet of the FPC can be avoided through the avoidance hole.

[0016] The alignment jig in the utility model can be matched with the continuous FPC adhesive tape, so that each person can perform the pasting operation of multiple adhesive tape strips each time, thereby improving efficiency.
