Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, the present embodiment relates to a process for manufacturing mylar with a handle. This handle-equipped mylar includes: release film a and mylar b combined together, wherein release film a has a portion a1 beyond one side edge of mylar b, portion a1 forming the handle of mylar b. The handle is used for tearing off the release film a on the mylar b through the handle after the mylar b is attached to the surface of the device.

The processing technology of the embodiment comprises the following steps:

s1, performing first punching on the release film, forming the outline of one side edge of the handle area on the release film, and forming the positioning hole in a sleeving and punching mode.

As shown in fig. 2, in step S1, the outline of one side edge of the handle region and the positioning hole can be formed by first punching and sleeve punching, so that the outline and the positioning hole can be used as a basis for positioning of the second punching. In one embodiment, the first die cutting is performed on the release film by a first cutting die 1, and the first cutting die 1 includes: a first blade edge 11 adapted to contour an edge of one side of the handle region when die cut. The first blade 11 is a flat blade.

Accordingly, the positioning hole is punched by the second cutting die 2 having the circular blade 21. In one embodiment, the positioning holes are distributed on both sides of the contour of one side edge of the formed handle area. One positioning hole is arranged at one side, and two positioning holes are arranged at the other side.

And S2, compounding the mylar on a release film, positioning the mylar and the release film by taking the positioning hole as a reference, and punching the mylar and the release film for the second time to form the outline of the mylar finished product and the outline of the rest edges of the handle area compounded on the mylar finished product at one time.

As shown in fig. 3, in step S2, the mylar profile and the handle are punched out by the secondary punching, and the whole product can be obtained after the waste is removed, so that the mylar size at the handle is not required to be controlled by the bushing punching, and is directly controlled by the size of the die. Therefore, the processing difficulty is reduced, and the processing precision of the product is improved.

In one embodiment, the third die cutting is performed on the release film by a third cutting die 3, and the third cutting die 3 includes: a third cutting edge 31 adapted to form the profile of the finished mylar product when die cut and to compound the profile of the remaining edge of the handle area on the mylar product. The first region 311 surrounded by the edge of the third blade 31 corresponds to the area of the mylar product to be punched out, and the third region 312 surrounded by the edge corresponds to the area of the handle to be punched out.

With the above embodiment of the first cutting die 1, the length L of the first cutting edge 11 is greater than the width W of the third cutting edge 31, so that the third cutting die 3 can keep tangent with the first cutting die 1 during punching, thereby facilitating formation of a closed handle area, and facilitating removal of mylar waste on a subsequent release film handle while realizing formation of the release film handle.

In conclusion, the processing technology of the handle mylar provided by the invention achieves the purposes of cutting out the handle of the release film, ensuring the size of the mylar and well discharging waste by separately punching the release film and the mylar. By adopting the process, high-precision products can be produced and the processing difficulty is greatly reduced for various Mylar with the structure. The product has better yield and mass production.
