Process for avoiding arching during fitting of material belt and product

Abstract

The invention relates to a process for avoiding arching when a material belt is attached to a product. The process comprises the following specific steps: enabling a raw material belt with a bearing film, a double-sided adhesive tape and an auxiliary release film to pass through a die-cutting machine; the first-step punching, the second-step punching, the third-step punching, the fourth-step punching and the fifth-step punching are sequentially carried out through the first punching cutter die, the second punching cutter die, the third punching cutter die, the fourth punching cutter die and the fifth punching cutter die respectively, and a finished product is obtained after waste materials on the periphery of the product or waste materials in a cutter line frame are removed. Compared with the prior art, when redundant waste on the periphery of a product is discharged, a part of waste is designed to be reserved on an appearance cutter of the four-punching-cutter die until a material belt is punched, and then the waste is discharged, so that the bonding area of the material belt and the product can be increased, the problem of product displacement caused by arching of the material belt is perfectly solved, and the problem that the material belt is prone to arching due to the fact that the product is small and the bonding area is increased is solved; and the problem that unqualified products are generated due to arching is solved, so that the research and development cost of the products is reduced, and the use experience of customers is enhanced.

Description

Technical Field

[0001] The present invention relates to the field of die-cutting technology, and in particular to a process for avoiding the arching of the tape and the product during lamination. Background Art

[0002] Double-sided tape is a roll-shaped adhesive tape made by using paper, cloth, or plastic film as the base material and uniformly coating an elastomeric pressure-sensitive adhesive or a resin-based pressure-sensitive adhesive on the above base material. It consists of three parts: the base material, the adhesive, and the release paper (film). According to the glue property, it can be divided into solvent-based adhesive tape (oil-based double-sided tape), emulsion-based adhesive tape (water-based double-sided tape), hot-melt adhesive tape, calendered adhesive tape, and reactive adhesive tape. Double-sided tape has characteristics such as high temperature resistance, solvent resistance, anti-aging, and good adhesion, and its performance is stable and reliable.

[0003] As Figure 1 shown, the commonly used manufacturing method in this industry is: attaching the double-sided tape raw material to the release surface of the release film, first using a die to cut out the product shape, and then laminating the tape and punching the product tape. Since the glue area of the product is small and the tape is not firmly bonded, the tape is prone to arching during lamination, resulting in poor product displacement. However, since the double-sided tape plays a role of fixed bonding on the workpieces of electronic products, with the increasingly fierce market competition and the growing demand for automated roll materials, if the product is displaced on the tape, it will cause the automated equipment to be unable to pick up the product normally, resulting in misalignment during lamination; Summary of the Invention

[0004] The purpose of the present invention is to provide a process for avoiding the arching of the tape and the product during lamination, which is used to solve the problem of obtaining unqualified products due to the arching of the tape resulting in product displacement.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A process for avoiding the arching of the tape and the product during lamination, the specific steps are as follows:

[0007] Pass the raw material tape with a carrier film, double-sided tape, and auxiliary release film through a die-cutting machine, and perform one-step punching, two-step punching, three-step punching, four-step punching, and five-step punching respectively through a first punching die, a second punching die, a third punching die, a fourth punching die, and a fifth punching die. After removing the waste material outside the product or the waste material within the knife line frame, the finished product is obtained;

[0008] The fourth punching die is provided with a fourth punching knife line A, a fourth punching knife line B, a fourth punching knife line C, and a fourth punching knife line D. The fourth punching knife line D is provided at the upper and lower ends of the fourth punching knife line C. A plurality of fourth punching knife lines C are provided between the two fourth punching knife lines D. One fourth punching knife line C is provided on one side of the fourth punching knife line B, and two fourth punching knife lines A are provided on the other side of the fourth punching knife line B.

[0009] The fifth punching die is symmetrically provided with two fifth punching knife lines up and down;

[0010] After four-step punching, the waste outside the four-punch knife line C is removed, and the waste in the shaded part is retained; after five-step punching, the waste in the shaded part is removed.

[0011] Furthermore, a first punch knife line A, a first punch knife line B, and a first punch knife line C are provided on the first punch die. The first punch knife line C is provided at the upper and lower ends of the first punch knife line B. A plurality of first punch knife lines B are provided between the two first punch knife lines C.

[0013] In the above further step, a positioning hole knife line group and a positioning pin knife line group are provided on the outside of each of the two first punch knife lines C. The distance range between the outermost ends of the two positioning hole knife line groups is 75 - 80 mm, preferably 77.8 mm.

[0014] Furthermore, after the first-step punching, the waste between the first punch knife line B and the first punch knife line C is removed.

[0015] Furthermore, a second punch knife line C, a second punch knife line B, and a second punch knife line A are provided on the second punch die in sequence from left to right.

[0016] In the above further step, the left-right width range of the second punch knife line B is 4 - 5 mm, preferably 4.60 mm, and the up-down length range of the second punch knife line B is 6 - 7 mm, preferably 6.64 mm.

[0017] In the above further step, the diameter range of the second punch knife line A is 2 - 3 mm, preferably 2.04 mm.

[0018] Furthermore, after the second-step punching, the waste outside the second punch knife line B is removed.

[0022] Furthermore, the distance range between the fifth punch knife lines is 50 - 60 mm, preferably 55.70 mm.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] When discharging the excess waste around the product of the present invention, a part of the waste is designed to be left on the outer shape knife of the four-station die until the strip is cut, so as to increase the bonding area between the strip and the product, perfectly solve the problem of product displacement caused by the arching of the strip, and solve the problem that due to the small size of the product, increasing the bonding area makes the strip prone to arching; solve the problem of generating unqualified products caused by arching, thereby reducing the R & D cost of the product and enhancing the customer's use experience.
