Description

Technical Field

[0001] The invention belongs to the technical field of die-cutting processing and relates to a die-cutting tool set and a die-cutting process thereof. Background Art

[0002] When processing double-sided adhesive and release film products, you will often encounter many round holes in the product, and the round holes are very close to the edge, such as Figure 1 As shown in A, the distance between the circular hole and the edge is only 0.5mm. Due to the limitations of existing technology and cost (when making a die for punching products, a 0.5mm gap cannot be made by ordinary machinery), this type of product cannot be formed in one step during processing, and the die needs to be split into two pieces, as shown in Figure 1. Figure 2 and Figure 3 As shown in the figure, it is divided into two steps. The first step is to make the round hole, and the second step is to make the outer frame. In this process, because the round hole is too close to the edge line, the glue on the edge line will usually go into the round hole when the die is cut. Figure 4 As shown in the figure, the tip of the die cutter will squeeze the double-sided adhesive tape at that position to both sides, causing the double-sided adhesive tape at the edge of the round hole to be squeezed into the round hole, resulting in the problem of excess material in the round hole. This kind of product is absolutely unacceptable to the customer and is considered an NG product. On the contrary, if the punching order is reversed, the outer frame is punched in the first step and the round hole is punched in the second step, the adhesive tape will be squeezed outward when punching the round hole, and the product is also NG. Summary of the invention

[0003] The purpose of the present invention is to provide a die-cutting tool set and a die-cutting process thereof, so as to solve the problem of glue overflow at the edge of the die-cut product.

[0004] The purpose of the present invention can be achieved by the following technical solutions:

[0005] A die-cutting tool set, comprising an auxiliary die, a punching die and a frame die;

[0006] The auxiliary cutting die comprises an auxiliary pressing plate and auxiliary hole cutting lines and auxiliary frame cutting lines arranged on the auxiliary pressing plate;

[0007] The punching knife die comprises a punching plate and a punching knife line arranged on the punching plate;

[0008] The frame cutting die comprises a frame pressing plate and a frame cutting line arranged on the frame pressing plate;

[0009] In the combined knife diagram of the auxiliary knife die, punching knife die and frame knife die, the auxiliary hole knife line is arranged inside the punching knife line, the auxiliary frame knife line is arranged outside the frame knife line, and the distance between the auxiliary hole knife line and the punching knife line, and the distance between the auxiliary frame knife line and the frame knife line are both smaller than the distance between the punching knife line and the frame knife line.

[0010] The combined knife diagram is a projection diagram of each knife line after the auxiliary knife die, the punching knife die and the pressing plate in the frame knife die are overlapped.

[0011] Furthermore, in the closed knife diagram, the distance between the punching knife line and the frame knife line is less than 0.5 mm.

[0012] Furthermore, in the knife closing diagram, the auxiliary hole knife line and the punching knife line are arranged concentrically.

[0013] Furthermore, in the knife closing diagram, the radius of the auxiliary hole knife line is 0.1-0.5 mm smaller than the radius of the punching knife line.

[0014] Furthermore, in the knife closing diagram, the radius of the auxiliary hole knife line is 0.3 mm smaller than the radius of the punching knife line.

[0015] Furthermore, in the knife closing diagram, the auxiliary border knife line is arranged parallel to the border knife line.

[0016] Furthermore, in the knife closing diagram, the distance between the auxiliary border knife line and the border knife line is 0.1-0.5 mm.

[0017] Furthermore, in the knife-closing diagram, the distance between the auxiliary border knife line and the border knife line is 0.3 mm.

[0018] Furthermore, in the knife closing diagram, the length of the auxiliary border knife line is 1.5-0 mm shorter than the diameter of the punching knife line.

[0019] Furthermore, in the closed knife diagram, the length of the auxiliary border knife line is 1 mm shorter than the diameter of the punching knife line.

[0020] A die-cutting process of the die-cutting tool set as described above includes first using an auxiliary die to punch the material, and then punching with a punching die and a frame die respectively, so that the overflow glue on the edge of the material can be removed together with the waste, thereby solving the problem of overflow glue on the edge of the die-cut product.

[0021] Working principle: Figure 4As shown, when the cutting die is punching downward, the double-sided adhesive layer between the release film layers will be squeezed to both sides. The closer the edge is to the cutting line, the stronger the degree of squeezing is, and the more overflow glue is generated. Taking the punching of the frame first and then the punching of the circular hole as an example, after the punching of the auxiliary cutting die, the auxiliary hole (produced by the punching of the auxiliary hole cutting line) and the auxiliary line (produced by the punching of the auxiliary frame cutting line) are respectively generated. When the frame cutting die is punching, since the distance between the punching position and the auxiliary line is smaller than the distance between it and the auxiliary hole, the extrusion effect of the punching makes the overflow glue on one side of the auxiliary hole less, and the overflow glue generated on the side of the auxiliary line will be discharged together with the waste. Similarly, when the punching die is punching, since the distance from the punching position to the auxiliary hole is smaller than the distance to the frame line (produced by the punching of the frame cutting line), the extrusion effect caused by the punching process on one side of the frame line is smaller, and the overflow glue generated on this side is less, and the overflow glue generated on the auxiliary hole side will be discharged together with the waste, and finally the punching hole and frame line with less overflow glue are obtained.

[0022] Compared with the prior art, the present invention has the advantages of simple structure and easy operation, and can effectively solve the problem of glue overflow between round holes and edges, which is beneficial to improving the qualified rate of products and reducing the time for inspectors to inspect products, thereby reducing labor costs and improving production efficiency.
