The straight blades are parallel and located on the outside respectively; the blades of the second height include four rectangular blades with chamfers, and the arrangement of the four rectangular blades is consistent with the arrangement of the four short straight blades.

Positioning hole blades are respectively provided on both sides of the first height blade, and the positioning hole blades are also second height blades. Correspondingly, positioning columns are respectively provided on both sides of the second height blade.

The height of the blade at the first height is 1.4 mm, and the height of the blade at the second height is 1.5 mm.

The present invention simultaneously provides the production process of the PI single-sided adhesive tape used for panel computer assembly, and the PI single-sided adhesive tape is sequentially from top to bottom a release film in the process, a PI single-sided adhesive tape, and a blue PET protective film; its production process includes the following steps: Use the double-station integrated forming tool to cut the material belt from top to bottom, and the material belt from top to bottom is the in-process release film, PI single-sided tape, and blue PET protective film; The release film and the single-sided tape are cut off from the middle by the blade at the first height to form an edge of the PI single-sided tape, and four positioning holes are punched out on the tape with four positioning hole blades; The belt then moves step by step to the station where the rectangular blade is located, and uses four positioning columns to cooperate with the positioning holes on the material belt to complete the positioning of the material belt. The surface tape and the lower layer of blue PET protective film are all cut off, the die-cutting is completed, and the waste is removed through the subsequent process to obtain the finished product.

The present invention reduces the use of machines through the above cutter structure and production process, thereby reducing the matching tolerance caused by multi-machine production, improving product precision, reducing operators, reducing production and labor costs, and improving enterprise competitiveness.

Detailed ways:

The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

As shown in Figure 1, a PI single-sided adhesive tape double-station integrated forming tool for tablet computer assembly according to the present invention includes a steel plate matrix 1 and a vertical inner wall milled out by an engraving machine on the surface of the steel plate matrix 1. The blade at 40° to the inner wall, the steel plate matrix 1 is in the shape of a cuboid plate with a thickness of generally 8mm, wherein: the blade of the blade is divided into a first height blade 11 and a second height blade 12, wherein the first height blade 11 includes four equal lengths The short straight blades 111 and the arc blades 112 respectively arranged at the ends of the four short straight blades 111, two of the four short straight blades 111 are on the same straight line and are opposite to the other two on the same straight line. Parallel state, that is, arranged in a 2x2 format, the first height blade 11 also includes two long straight blades 113, the two long straight blades 113 are parallel to the short straight blades 111 and are located on the outside respectively, and their length is longer than the two short straight blades 111 And the projected lengths of the four arc-shaped blades 112; the second height blade 12 includes four rectangular blades 121 with chamfers, and the arrangement of the four rectangular blades 121 is consistent with the arrangement of the four short straight blades 111, that is, also in the 2x2 format arrangement.

Positioning hole blades 122 are respectively provided on both sides of the first height blade 11 , and the positioning hole blades 122 also belong to the second height blade 12 . Correspondingly, positioning posts 13 are respectively provided on both sides of the second height blade 12 .
