Description

Technical Field

[0001] This invention relates to the field of die-cutting technology, and in particular to a die-cutting process and die-cutting equipment. Background Technology

[0002] Some die-cut workpieces include ring-shaped semi-finished products. For these ring-shaped semi-finished products, although the layout on the film material is relatively tight, there is a large hollow area in the middle of the ring-shaped semi-finished product. After the ring-shaped semi-finished product is die-cut on the film material, a large area on the film material is still unused due to the existence of the hollow area, resulting in a large waste of film material. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art. The first aspect of this invention provides a die-cutting process that can improve the utilization rate of film materials.

[0004] A second aspect of the present invention also provides a die-cutting apparatus.

[0005] A die-cutting process according to a first aspect of the present invention includes the following steps: The first membrane material, the first carrier membrane, and the second carrier membrane are stacked sequentially, wherein the first membrane material and the first carrier membrane together constitute the first composite material; A pre-finished product is die-cut from a first composite material, and a second semi-finished product is die-cut from a first film material, wherein the second semi-finished product is annular and the pre-finished product is located between the second semi-finished products, and the pre-finished product includes the first semi-finished product die-cut from the first film material; The first carrier film and the second carrier film are separated so that the pre-finished product is attached to the second carrier film and the second semi-finished product is attached to the first carrier film; The first semi-finished product is processed into the first finished product, and the second semi-finished product is processed into the second finished product.

[0006] The die-cutting process of the present invention has at least the following beneficial effects: In the die-cutting process of this embodiment, firstly, a first film material, a first carrier film, and a second carrier film are stacked sequentially, wherein the first film material and the first carrier film are combined to form a first composite material through a pressing process. Next, a die-cutting operation is performed on the first composite material: multiple pre-finished products are die-cut at target positions using a punching device, and second semi-finished products are simultaneously die-cut on the first film material. The second semi-finished products are designed as a ring structure, and each first semi-finished product is located within a hollow area between the second semi-finished products. The pre-finished products include the first semi-finished products die-cut from the first film material. Subsequently, film layer separation is performed: the first carrier film and the second carrier film are separated using a peeling device, allowing the pre-finished products to be transferred and adhered to the second carrier film, while the second semi-finished products remain and adhere to the first carrier film. Finally, in the processing stage: the first semi-finished products undergo additional processing such as die-cutting or lamination to form the first finished product, and the second semi-finished products undergo similar processing to form the second finished product. From the above, it can be seen that this application maximizes the utilization rate of the film material by effectively utilizing the hollow area of ​​the ring-shaped second semi-finished product for the layout of the first semi-finished products.

[0010] According to a die-cutting process based on a first aspect of the present invention, a second semi-finished product is processed into a second finished product, comprising the following steps: The sixth semi-finished product was produced by die-cutting, and the seventh semi-finished product was also produced by die-cutting. The second semi-finished product is laminated onto the sixth semi-finished product; The seventh semi-finished product is compounded onto the side of the second semi-finished product that is opposite to the sixth semi-finished product to form the second finished product.

[0011] According to a die-cutting process of a first aspect of the present invention, laminating a second semi-finished product onto a sixth semi-finished product includes the following steps: Multiple first adhesive blocks are laminated onto the sixth semi-finished product, and the multiple first adhesive blocks are distributed at intervals along the circumference. The second semi-finished product is laminated onto the sixth semi-finished product, and the first adhesive block is positioned between the second and sixth semi-finished products.

[0012] According to a first aspect of the present invention, a die-cutting process for laminating a plurality of first adhesive blocks onto a sixth semi-finished product includes the following steps: Multiple first masks arranged side by side are laminated onto the sixth semi-finished product; Each of the first face films is die-cut to form a first adhesive block.

[0013] According to a die-cutting process of a first aspect of the present invention, a seventh semi-finished product is laminated onto the side of a second semi-finished product opposite to the sixth semi-finished product, comprising the following steps: Multiple second adhesive blocks are laminated on the side of the second semi-finished product that is opposite to the sixth semi-finished product, and the multiple second adhesive blocks are distributed at intervals along the circumference. The seventh semi-finished product is laminated onto the second semi-finished product, and the second adhesive block is positioned between the second semi-finished product and the seventh semi-finished product.

[0022] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0023] The following is for reference. Figures 1 to 7 A die-cutting process according to a first aspect of the present invention will be described in detail.

[0024] refer to Figure 1 , Figure 6 and Figure 7 According to a first aspect of the present invention, a die-cutting process includes the following steps: Step S100: The first membrane material, the first carrier membrane, and the second carrier membrane are stacked sequentially, wherein the first membrane material and the first carrier membrane together constitute the first composite material; Step S200: Die-cut a pre-finished product on the first composite material and die-cut a second semi-finished product 210 on the first film material, wherein the second semi-finished product 210 is annular and the pre-finished product is located between the second semi-finished products 210, and the pre-finished product includes the first semi-finished product die-cut from the first film material; Step S300: Separate the first carrier film and the second carrier film to allow the pre-finished product to be attached to the second carrier film and the second semi-finished product 210 to be attached to the first carrier film; Step S400: Process the first semi-finished product into the first finished product 100, and process the second semi-finished product 210 into the second finished product 200.

[0025] In the die-cutting process of this embodiment, firstly, a first film material, a first carrier film, and a second carrier film are stacked sequentially, wherein the first film material and the first carrier film are combined to form a first composite material through a pressing process. Next, a die-cutting operation is performed on the first composite material: multiple pre-finished products are die-cut at target positions using a punching device, and a second semi-finished product 210 is simultaneously die-cut on the first film material. The second semi-finished product 210 is designed as a ring structure, and each first semi-finished product is located within a hollow area between the second semi-finished products 210. The pre-finished products include the first semi-finished products die-cut from the first film material. Subsequently, film layer separation is performed: the first carrier film and the second carrier film are separated using a peeling device, allowing the pre-finished products to be transferred and adhered to the second carrier film, while the second semi-finished product 210 is retained and adhered to the first carrier film. Finally, in the processing stage: the first semi-finished product undergoes additional processing such as die-cutting or lamination to form a first finished product 100, and the second semi-finished product 210 undergoes similar processing to form a second finished product 200. As can be seen from the above, this application maximizes the utilization rate of the membrane material by effectively utilizing the hollowed-out area of ​​the annular second semi-finished product 210 to lay out the first semi-finished product.

[0026] It is understandable that by setting a first carrier film and a second carrier film, and simultaneously cutting through the first carrier film when the first semi-finished product is die-cut from the first film material, the first semi-finished product and the second semi-finished product 210 can be located on the second carrier film and the first carrier film respectively when the first carrier film and the second carrier film are separated in the future, thereby realizing the separation of the first semi-finished product from the hollow area of ​​the annular second semi-finished product 210.

[0027] refer to Figure 2 and Figure 6 In some embodiments of the present invention, two third semi-finished products 110 are arranged on the first semi-finished product, and the processing of the first semi-finished product into the first finished product 100 specifically includes, but is not limited to, the following steps: Step S410: Asynchronously transfer each of the first semi-finished products on the second carrier film to the first base film so that any two adjacent third semi-finished products 110 on the first base film are spaced at the same interval. Step S430: Die-cut the first semi-finished product to form two third semi-finished products 110; Step S440: Combine the third semi-finished product 110 with the fourth semi-finished product 120 to form the first finished product 100.

[0028] Understandably, the first semi-finished products, bonded to the second carrier film, are first transferred to the first backing film via an asynchronous transfer process. During transfer, the position of each semi-finished product is controlled to ensure a uniform spacing between any two adjacent semi-finished products on the first backing film. Then, the transferred semi-finished products are die-cut to form two separate third semi-finished products 110. Finally, in the lamination stage, each third semi-finished product 110 is laminated with a fourth semi-finished product 120 using a laminating device to ultimately form the first finished product 100. Asynchronous transfer ensures the uniform distribution of the third semi-finished products 110 on the backing film, facilitating subsequent high-precision die-cutting and lamination operations. This not only improves processing efficiency and reduces alignment errors but also lowers the risk of displacement of the semi-finished products during the transfer process, enhancing product consistency.

[0029] like Figure 2 and Figure 6 As shown, in some embodiments, the first finished product 100 further includes a fifth semi-finished product 130, and the following steps are included before step S430: Step S420: Two fifth semi-finished products 130 are laminated onto each first semi-finished product, and the fifth semi-finished products 130 are laminated onto the area on the first semi-finished product where the third semi-finished product 110 is arranged.

[0030] Understandably, before die-cutting the first semi-finished product, two fifth semi-finished products 130 are laminated onto each first semi-finished product. The fifth semi-finished products 130 are positioned and laminated onto the first semi-finished products to form the area of ​​the third semi-finished product 110, achieving a firm bond through an adhesive process. Only then is the die-cutting operation performed to form the third semi-finished product 110. By pre-laminating the fifth semi-finished products 130, subsequent processes are simplified, reducing individual processing steps. At the same time, this design optimizes the structural strength of the first semi-finished products, enhancing support in the area where the fifth semi-finished products 130 are laminated onto the first semi-finished products, thereby improving the overall performance and reliability of the first finished product 100.

[0031] like Figure 2 and Figure 6 As shown, in some embodiments, step S440 includes, but is not limited to, the following steps: Step S441: Sequentially laminate each of the third semi-finished products 110 onto the second membrane material; Step S442: Die-cut the second film material to form multiple fourth semi-finished products 120, and make the fourth semi-finished products 120 correspond one-to-one with the third semi-finished products 110 and fit together.

[0032] Understandably, firstly, the die-cut third semi-finished products 110 are arranged sequentially and laminated onto the second film material, with accurate positioning ensured by an automatic conveying system. Then, the second film material is die-cut a second time to form multiple fourth semi-finished products 120; the cutting position is precisely controlled so that each fourth semi-finished product 120 corresponds one-to-one with the third semi-finished product 110 and is bonded together to form a complete first finished product 100.

[0033] This implementation adopts a sequential composite and then die-cutting strategy, which improves the matching accuracy of semi-finished products and reduces the probability of avoiding misalignment problems. At the same time, by batch processing the fourth semi-finished product 120 on a single film material, production efficiency is optimized and scrap material is reduced.

[0034] refer to Figure 3 and Figure 7 In some embodiments of the present invention, step S400 includes the following steps: Step S450: Die-cut the sixth semi-finished product 220 and the seventh semi-finished product 230. Step S460: Composite the second semi-finished product 210 onto the sixth semi-finished product 220; Step S470: The seventh semi-finished product 230 is bonded to the side of the second semi-finished product 210 that is away from the sixth semi-finished product 220 to form the second finished product 200.

[0035] Understandably, the process involves first die-cutting to produce the sixth semi-finished product 220 and the seventh semi-finished product 230. Then, the second semi-finished product 210, which is bonded to the first carrier film, is transferred and laminated onto the sixth semi-finished product 220. Finally, the seventh semi-finished product 230 is laminated onto the side of the second semi-finished product 210 opposite to the sixth semi-finished product 220 to complete the assembly of the second finished product 200. By using a step-by-step die-cutting and lamination process for the annular second semi-finished product 210, its annular structure is fully utilized as an intermediate layer, reducing processing waste. At the same time, the lamination process enhances the structural integrity of the second finished product 200.

[0036] like Figure 3 and Figure 7 As shown, in some embodiments, step S460 includes the following steps: Step S461: Composite multiple first adhesive blocks 240 onto the sixth semi-finished product 220, wherein the multiple first adhesive blocks 240 are distributed at intervals along the circumferential direction; Step S462: The second semi-finished product 210 is laminated onto the sixth semi-finished product 220, and the first adhesive block 240 is positioned between the second semi-finished product 210 and the sixth semi-finished product 220.

[0037] Understandably, multiple first adhesive blocks 240 are laminated onto the sixth semi-finished product 220, and the first adhesive blocks 240 are arranged in a spaced-apart manner along the circumference of the sixth semi-finished product 220. Then, the second semi-finished product 210 is laminated onto the sixth semi-finished product 220, so that the first adhesive blocks 240 are pressed between the second semi-finished product 210 and the sixth semi-finished product 220. The distribution design of the first adhesive blocks 240 enhances the interfacial bonding strength, which is particularly suitable for flexible materials; its spaced layout also ensures the breathability of the adhesive layer or reduces stress concentration under pressure.

[0038] like Figure 3 and Figure 7 As shown, in one embodiment, step S461 includes the following steps: Step S461a: Composite multiple first masks arranged side by side onto the sixth semi-finished product 220; Step S461b: Die-cut each of the first masks to form each of the first adhesive blocks 240.

[0039] Understandably, multiple first masks are directly laminated onto the sixth semi-finished product 220. Then, each of the multiple first masks is precisely cut and die-cut to remove unnecessary parts, forming separate block-shaped first adhesive blocks 240. This simplifies the manufacturing of the first adhesive blocks 240, avoids the process of prefabricating adhesive blocks separately, increases production speed, and reduces material waste.

[0040] It should be noted that the multiple first adhesive blocks 240 are divided into multiple groups, and the first adhesive blocks 240 in each group are distributed at intervals along the width direction of the sixth semi-finished product 220. Each first adhesive block 240 in the same group is cut and formed on the same first film.

[0041] like Figure 4 and Figure 7 As shown, in some embodiments, step S470 includes the following steps: Step S471: On the side of the second semi-finished product 210 that is opposite to the sixth semi-finished product 220, multiple second adhesive blocks 250 are bonded together, and the multiple second adhesive blocks 250 are distributed circumferentially at intervals. Step S472: The seventh semi-finished product 230 is laminated onto the second semi-finished product 210, and the second adhesive block 250 is located between the second semi-finished product 210 and the seventh semi-finished product 230.

[0042] Understandably, multiple second adhesive blocks 250 are laminated to the side of the second semi-finished product 210 opposite to the sixth semi-finished product 220, with the second adhesive blocks 250 spaced apart circumferentially along the second semi-finished product 210. Then, the seventh semi-finished product 230 is pressed onto it, ensuring that the second adhesive blocks 250 are positioned in the middle to form a buffer layer. The spaced distribution of the second adhesive blocks 250 not only optimizes adhesion but also enhances the impact resistance of the second finished product 200, making it suitable for precision component assembly; simultaneously, the distribution design avoids interference from the adhesive blocks to the central area of ​​the annular structure.

[0043] like Figure 5 and Figure 7 As shown, in one embodiment, step S471 includes the following steps: Step S471a: Apply multiple second masks onto the base film; Step S471b: Die-cut the multiple second films separately to form each second adhesive block 250 on the base film; Step S471c: Transfer each of the second adhesive blocks 250 on the base film to the second semi-finished product 210.

[0044] Understandably, multiple second face masks are first laminated onto an independent base film. These second face masks are then die-cut to form separate second adhesive blocks 250 on the base film. Finally, the second adhesive blocks 250 on the base film are individually transferred to their target positions on the second semi-finished product 210. Using the base film as an intermediary carrier avoids the risks of directly handling the fragile second face masks; the transfer process ensures high-precision positioning of the second adhesive blocks 250, improving the lamination quality and reducing the breakage rate.

[0045] According to a second aspect of the present invention, a die-cutting apparatus is used to implement the die-cutting process as described in the first aspect of the present invention.
