A die-cutting process of a double-sided tape composite product and a production line thereof according to an embodiment of the present invention will be described with reference to fig. 1 to 22.
As shown in fig. 1 to 21, the die cutting process for a double-sided adhesive tape composite product according to the embodiment of the first aspect of the present invention includes the following steps:
s100: sequentially compounding the first film 100, the second film 200 and the double-sided adhesive tape 300 to form a third semi-finished product; at least one of the first film 100 and the second film 200 is a low-adhesive film so that the first film 100 and the second film 200 can be adhered to each other, a through hole 210 is formed on the second film 200, and the double-sided tape 300 is adhered to the first film 100 through the through hole 210;
s200: die-cutting the double-sided adhesive tape 300 in the third semi-finished product to form a fourth semi-finished product, so that the double-sided adhesive tape 300 is formed with a first structure 310, and the first structure 310 is located in the area of the double-sided adhesive tape 300 corresponding to the through hole 210;
s300: the second film 200 is collected to take away the rim charge of the double-sided adhesive tape 300, so as to form a fifth semi-finished product;
referring to fig. 1, 9 to 11, 19 and 20, by sequentially laminating the second film 200 with the through hole 210 and the double-sided tape 300 on the first film 100, a portion of the double-sided tape 300 can be directly attached to the second film 200, and another portion of the double-sided tape 300 is attached to the first film 100 through the through hole 210, at this time, the die-cut double-sided tape 300 forms a first structure 310 corresponding to the through hole 210, that is, a hole material of the double-sided tape 300, and oppositely, an edge material of the double-sided tape 300 is also formed. At this time, when the rim charge of the double-sided tape 300 is taken away through the second film 200, at least one of the first film 100 and the second film 200 is a low-adhesive film, the rim charge of the double-sided tape 300 can be adhered to the second film 200, or the hole charge of the double-sided tape 300 can be adhered to the first film 100, so that the rim charge of the double-sided tape 300 and the hole charge of the double-sided tape 300 can be easily separated to form a fifth semi-finished product, the pulling deformation is reduced, and the yield of the double-sided tape 300 product after die cutting is improved.
At least one of the first film 100 and the second film 200 is a low-viscosity film, and the other film may be a release film, a raw film, a composite film, a low-viscosity film, or the like, which can be used to attach the double-sided tape 300.
It should be understood that when die-cutting the third semi-finished double-sided adhesive tape 300, the first structure 310 is located in the area of the double-sided adhesive tape 300 corresponding to the through hole 210, and one is that die-cutting can be performed along the edge of the through hole 210 of the second film 200, so that the first structure 310 and the through hole 210 completely correspond, and the size of the first structure 310 is the same as that of the through hole 210; alternatively, the double-sided adhesive tape 300 may be die-cut inside the area corresponding to the through hole 210, so that the size of the first structure 310 is smaller than that of the through hole 210. The size of the first structure 310 in the embodiment of the present application is smaller than that of the through-hole 210.
S400: attaching the first release surface to one surface of the fifth semi-finished product, which is exposed out of the first structure 310, and removing the rim charge of the first release surface after die cutting the first release surface to form a sixth semi-finished product, so that the first release surface forms a second structure 410; wherein the second structure 410 corresponds to the first structure 310 and is larger than the first structure 310;
s500: attaching the first low-adhesive film 500 to the surface of the sixth semi-finished product, which is covered with the second structure 410, and removing the first film 100 to form a seventh semi-finished product;
s600: and attaching the surface of the seventh semi-finished product, which is exposed out of the first structure 310, to the second release surface 600 to form a first composite product.
Referring to fig. 1, 11 to 14 and 21, a first release surface is attached to one side of the fifth semi-finished product exposing the first structure 310, a first release surface is die-cut to form a second structure 410 corresponding to the first structure 310, a rim charge of the first release film is discharged to form a sixth semi-finished product, then a first low-adhesive film 500 is attached to one side of the sixth semi-finished product exposing the second structure 410, the first film 100 is removed and then attached to the second release surface 600, so that a first composite product formed by the first release surface rim charge and the second release surface 600 respectively covering two sides of the rim charge of the double-sided tape 300 is formed, since a knife mark generated by die-cutting the double-sided tape 300 is dropped on the first film 100, the first film 100 is discharged during the production process, and no knife mark is generated on the first release surface rim charge and the second release surface 600, thereby facilitating the tearing when the double-sided tape 300 is used by a client.
Specifically, since the first release surface is die-cut to form the second structure 410, the second structure 410 is larger than the first structure 310, and thus a knife mark at the time of die-cutting may fall on the first film 100, thereby preventing a knife mark on the second structure 410 from being generated, which may cause an overflow of glue.
The first low-adhesive film 500 plays a role of a transfer film, and is used for conveniently removing the first film 100 in the coiled material after bearing the second structure 410 and the first structure 310, so that the surface of the seventh semi-finished product, which is exposed out of the first structure 310, is conveniently attached to the second release surface 600, and finally the first composite product is formed.
Referring to fig. 2, step S100 further includes the following steps:
s110: die cutting the second film 200 such that the second film 200 is formed with the through-hole 210;
s120: compounding one side of the die-cut second film 200 with the first film 100;
s130: and compounding the other side of the die-cut second film 200 with the double-sided adhesive tape 300.
It can be understood that the second film 200 is die-cut to generate the through hole 210, the die-cut second film 200 is attached to the first film 100, since at least one of the second film 200 and the first film 100 is a low-viscosity film, the first film 100 and the second film 200 can be adhered to each other, and then the double-sided tape 300 is laminated on the other side of the second film 200, so that a part of the double-sided tape 300 is attached to the second film 200, and another part of the double-sided tape 300 can be attached to the first film 100 through the through hole 210, and finally the third semi-finished product is formed.
