Description

Technical Field

[0001] This application relates to the field of die-cutting technology, and in particular to a die-cutting process for integrated parts. Background Technology

[0002] In related technologies, the traditional processing method involves developing and shipping several die-cut products separately. Once at the customer's location, multiple assembly lines are needed to assemble the die-cut products. However, this not only increases packaging costs but also increases the workload for the customer. Reassembling multiple die-cut products at the customer's location also increases the customer's requirements for precision control, which not only reduces customer satisfaction but also increases unnecessary processing costs. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes an integrated component die-cutting process that can reduce material costs, reduce die-cutting steps, improve efficiency, and simultaneously reduce misalignment errors caused by separate mounting, thereby improving mounting accuracy.

[0004] According to a first aspect of the present invention, the die-cutting process for an integrated component includes the following steps: laminating a non-adhesive side of a first low-adhesion film with an adhesive side of a second low-adhesion film to form a first semi-finished product; preparing a plurality of first composites, each first composite including a first product, a first double-sided adhesive, and a first release film, wherein the first double-sided adhesive and the first release film are sequentially laminated onto one side of the first product; laminating the sides of the plurality of first composites with the first product to the adhesive side of the first semi-finished product respectively to form a second semi-finished product; and die-cutting the first low-adhesion film on the second semi-finished product to obtain a third semi-finished product.

[0005] The die-cutting process for integrated parts according to embodiments of the present invention has at least the following beneficial effects: This die-cutting process for integrated parts includes the following steps: preparing a plurality of first composite products, each first composite product comprising a first product, a first double-sided adhesive, and a first release film sequentially laminated together; laminating the non-adhesive side of the first low-adhesive film with the adhesive side of the second low-adhesive film to form a first semi-finished product, such that the two sides of the first semi-finished product are respectively the non-adhesive side of the second low-adhesive film and the adhesive side of the first low-adhesive film; subsequently laminating at least two first composite products with the first product side with the first semi-finished product with the first low-adhesive film side to form a second semi-finished product, such that the first product side of the first composite product is laminated with the adhesive side of the first semi-finished product, and the two sides of the second semi-finished product are respectively the non-adhesive side of the second low-adhesive film and the first release film; then die-cutting the second semi-finished product... The first low-adhesion film and the second low-adhesion film act as a support at the bottom of the first low-adhesion film, thereby reducing damage to the die-cutting mold and obtaining the first low-adhesion film for a single product. Therefore, the integrated die-cutting process of this application integrates multiple first composite products onto the first low-adhesion film.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0029] The following is for reference. Figures 1 to 3 The die-cutting process for integrated parts according to an embodiment of the present invention is described.

[0030] like Figures 1 to 3 As shown, the die-cutting process for integrated parts according to an embodiment of the present invention includes the following steps:

[0031] S100: The non-adhesive side of the first low-adhesion film 100 is laminated with the adhesive side of the second low-adhesion film 900 to form the first semi-finished product;

[0032] S200: Prepare several first composite products, each first composite product including a first product, a first double-sided adhesive and a first release film, the first double-sided adhesive and the first release film being sequentially laminated onto one side of the first product;

[0033] S300: Multiple first composite products with one side of the first product are respectively bonded to the adhesive side of the first low-adhesion film, so that the multiple first composite products are bonded to the first semi-finished product to form a second semi-finished product;

[0034] S400: Die-cut the first low-adhesion film 100 on the second semi-finished product to obtain multiple third semi-finished products.

[0035] Understandably, this integrated die-cutting process includes the following steps: Preparing several first composite products, each comprising a first product, a first double-sided adhesive, and a first release film sequentially laminated together; laminating the non-adhesive side of the first low-adhesion film 100 with the adhesive side of the second low-adhesion film 900 to form a first semi-finished product, where the two sides of the first semi-finished product are the non-adhesive side of the second low-adhesion film 900 and the adhesive side of the first low-adhesion film 100, respectively; subsequently, laminating the side of at least two first composite products with the first product attached to the side of the first semi-finished product with the first low-adhesion film 100, thereby forming a second semi-finished product, where the first product of the first composite product is laminated with the adhesive side of the first semi-finished product, and the two sides of the second semi-finished product are the non-adhesive side of the second low-adhesion film 900 and the first release film, respectively; then die-cutting the first low-adhesion film 100 from the second semi-finished product, while the second low-adhesion film... The first low-adhesion film 900 acts as a support at the bottom of the first low-adhesion film 100, thereby reducing damage to the die-cutting mold and resulting in multiple sheets of the first low-adhesion film 100. Therefore, the integrated die-cutting process of this application integrates multiple first composite products onto the first low-adhesion film 100. In use, it is only necessary to peel off the remaining part of the third semi-finished product except for the second low-adhesion film 900 from the second low-adhesion film 900, remove the first release film, and then laminate the side of the first product with the first double-sided adhesive onto the product to be mounted. Then, peel off the first low-adhesion film 100, thereby achieving the effect of attaching multiple first products to the product to be mounted at the same time. That is, the multiple first composite products of this application share one first low-adhesion film 100, which not only reduces material costs but also reduces the die-cutting and assembly process, improving efficiency. In addition, simultaneous application onto the product to be mounted can reduce the misalignment error caused by separate mounting and improve the mounting accuracy.

[0036] Steps S100 and S200 are not sequential. Both the first and second low-adhesion films are low-adhesion films with adhesive on one side and no adhesive on the other side.

[0037] Specifically, the first product can be foam, Mylar, etc., and the product to be mounted can be a mobile phone motherboard, etc.

[0038] As shown in the figure, step S300 includes the following steps:

[0039] S310; A circular cutter is used to cut a strip of a second composite product from the first composite product. The second composite product includes a second product, a second double-sided adhesive, and a second release film. The side of the second composite product with the second product is placed on the adhesive side of the first semi-finished product to form a third composite product.

[0040] S320; After removing the second release film from the third composite, laminate the third release film onto the side exposing the second double-sided adhesive to form the fourth composite;

[0041] S330; used for die-cutting a third release film and a second product on a fourth composite with a rotary die, such that the second product forms a first hole material and a first frame waste, and the second double-sided adhesive forms a fourth hole material and a fourth frame waste, and the third release film forms a second hole material and a second frame waste;

[0042] S340; Remove the waste from the second frame, the fourth frame, and the first frame to form the second semi-finished product.

[0043] It is understood that step S300 includes the following steps: A strip of the second composite product, asynchronously die-cut from the first composite product, is placed onto the first semi-finished product using a circular die. That is, the die-cutting pitch of the first composite product is smaller than the pitch of the first semi-finished product, thereby saving material on the first composite product. The second composite product includes a strip of the second product, a second double-sided adhesive, and a second release film. The side of the second composite product with the second product is placed onto the side of the first semi-finished product with the first low-adhesion film 100, thus allowing the non-adhesive side of the second product to adhere to the first semi-finished product. The adhesive side of the low-adhesion film 100 is used to form a third composite product. Then, the strip-shaped second release film can be removed with tape. Then, the third release film is laminated onto the side exposing the second double-sided adhesive to form a fourth composite product. The fourth composite product is then die-cut to form a second product with a first frame waste and a first hole material of the desired shape. The second double-sided adhesive is correspondingly formed with a fourth hole material and a fourth frame waste. The third release film is formed with a second hole material and a second frame waste. After removing the second frame waste, the fourth frame waste, and the first frame waste, a second semi-finished product is obtained.

[0044] As shown in the figure, step S340 includes the following steps:

[0045] S341; After the waste from the second frame is removed by tape, a PET film is laminated onto the side with the second perforated material to form the fifth composite product;

[0046] S342; Remove the PET film from the fifth composite to take away the waste from the fourth and first frames, forming the second semi-finished product.

[0047] It is understood that step S340 includes the following steps: first, the second frame waste is removed by tape, and then a PET film is laminated onto the side of the material with the second hole exposed to form a fifth composite product. Since the second frame waste, which is a release film, cannot be bonded to the fourth frame waste, which is a double-sided adhesive, while the PET film can be bonded to the fourth frame waste, after the PET film is laminated, the fourth frame waste and the first frame waste can be removed by removing the PET film. After removing the second frame waste, the fourth frame waste and the first frame waste, a second semi-finished product is formed.

[0048] It is understood that the second composite product includes several sixth composite products and several seventh composite products. The length direction of the sixth composite product is along the feeding direction of the first composite product, and the length direction of the seventh composite product is perpendicular to the feeding direction of the first composite product. For example, as shown in Figures 1-2, in this embodiment, the second composite product can be a strip-shaped sixth composite product whose length is along the feeding direction of the first composite product, or it can be a strip-shaped seventh composite product whose length is perpendicular to the feeding direction of the first composite product. The processing sequence can be as follows: first, cut the strip-shaped sixth composite product, and after die-cutting out the corresponding second semi-finished product, cut the strip-shaped seventh composite product, and then die-cut out the corresponding second semi-finished product; or first, cut the strip-shaped seventh composite product, and after die-cutting out the corresponding second semi-finished product, cut the strip-shaped seventh composite product, and then die-cut out the corresponding second semi-finished product.

[0049] It should be understood that, in this embodiment, firstly, long strips of first and second foam are cut out along the feeding direction perpendicular to the first composite material. Then, L-shaped foam 200 and I-shaped foam 300 are die-cut from the first and second foams to form corresponding second semi-finished products. Next, long strips of first Mylar, third foam, and second Mylar are laminated on top, along the feeding direction of the first composite material. Then, corresponding square Mylar 500, T-shaped foam 400, and L-shaped Mylar 600 are die-cut from the first Mylar, third foam, and second Mylar.

[0050] As shown in the figure, step S310 includes the following steps:

[0051] S311; Use a circular cutter to cut out multiple sixth composite pieces simultaneously;

[0052] S312; Use a round cutter to cut out multiple seventh composite products simultaneously.

[0053] It is understood that there can be multiple sixth composite products in the third semi-finished product. In step S330, multiple sixth composite products can be die-cut simultaneously. For example, in this embodiment, the third foam, the first Mylar, and the second Mylar can be die-cut using the same circular die to simultaneously die-cut T-shaped foam 400, square Mylar 500, and L-shaped Mylar 600. Similarly, there can also be multiple seventh composite products in the third semi-finished product. For example, in this embodiment, the first foam and the second foam can also be die-cut simultaneously using the same circular die to simultaneously die-cut L-shaped foam 200 and I-shaped foam 300.

[0054] As shown in the figure, step S400 also includes the following steps:

[0055] S410: After laminating the fourth release film with the side of the second semi-finished product containing the first product, the third double-sided adhesive is laminated onto the fourth release film to form the ninth composite product.

[0056] S420: The fifth release film is laminated onto the side of the ninth composite with the third double-sided adhesive to form the tenth composite;

[0057] S430: Die-cut the fourth release film, the third double-sided adhesive, the fifth release film, and the first low-adhesion film 100 on the tenth composite product, and form the fourth release film with the first inner frame waste, the first frame material, and the first outer frame waste from the inside out, form the third double-sided adhesive with the second inner frame waste, the second frame material 700, and the second outer frame waste from the inside out, form the fifth release film with the third inner frame waste, the third frame material, and the third outer frame waste from the inside out, and form the first low-adhesion film 100 with the third hole material and the fourth frame material from the inside out;

[0058] S440: Discharge the waste from the first inner frame, the second inner frame, the third inner frame, the first outer frame, the second outer frame, the third outer frame, and the fourth frame material to obtain the third semi-finished product.

[0059] Understandably, step S400 also includes the following steps: first, laminating the fourth release film onto the side of the second semi-finished product containing the first product, then laminating the third double-sided adhesive onto the fourth release film, thus obtaining the ninth composite product. In this way, the third double-sided adhesive can adhere to the adhesive side of the first low-adhesion film 100 through the fourth release film, preventing the third double-sided adhesive from directly adhering to the first low-adhesion film 100 and causing it to stick together, which would hinder separation of the third double-sided adhesive from the first low-adhesion film 100. Subsequently, laminating the fifth release film onto the side of the ninth composite product containing the third double-sided adhesive, thus forming the tenth composite product. Then, die-cutting the fifth release film, the third double-sided adhesive, the fourth release film, and the first low-adhesion film 100 onto the tenth composite product, thereby shaping the fourth release film... The process involves forming a first inner frame waste, a first frame material, and a first outer frame waste from the inside out; forming a second inner frame waste, a second frame material 700, and a second outer frame waste from the inside out using a third double-sided adhesive; forming a third inner frame waste, a third frame material, and a third outer frame waste from the inside out using a fifth release film; and forming a third hole material and a fourth frame material from the inside out using a first low-adhesion film 100. The first inner frame waste, the second inner frame waste, and the third inner frame waste are vertically aligned, as are the first outer frame waste, the second outer frame waste, the third outer frame waste, and the fourth frame material. After removing the first inner frame waste, the second inner frame waste, the third inner frame waste, the first outer frame waste, the second outer frame waste, the third outer frame waste, and the fourth frame material, the third semi-finished product containing the first frame material, the second frame material 700, and the third frame material on the third hole material is obtained.

[0060] As shown in the figure, step S410 includes the following steps:

[0061] S411: The fourth release film is laminated with the side of the second semi-finished product containing the first product to form the eleventh composite product;

[0062] S412: Prepare several eighth composites, the eighth composites including a third double-sided adhesive, and a sixth release film and a seventh release film respectively laminated to both sides of the third double-sided adhesive;

[0063] S413: After removing the sixth release film of the eighth composite, the side with the third double-sided adhesive exposed will be laminated with the side of the eleventh composite with the fourth release film to form the twelfth composite.

[0064] S414: Remove the seventh release film of the twelfth composite to form the ninth composite.

[0065] Understandably, step S410 includes the following steps: laminating the fourth release film with the side of the second semi-finished product containing the first product to form an eleventh composite; preparing an eighth composite, which includes a sixth release film, a seventh release film, and a third double-sided adhesive, with the third double-sided adhesive located between the sixth and seventh release films; then removing the sixth release film from the eighth composite, laminating the side of the eleventh composite containing the fourth release film with the exposed third double-sided adhesive, to form a twelfth composite; subsequently removing the seventh release film from the twelfth composite to form a ninth composite.

[0066] It should be understood that step S413 includes the following steps: removing the sixth release film of the eighth composite, and then asynchronously die-cutting the seventh release film and the third double-sided adhesive onto the eleventh composite, so that a strip of the third double-sided adhesive and the seventh release film are placed on the side of the eleventh composite with the fourth release film, thereby forming the twelfth composite.

[0067] It should be understood that steps S411 and S412 are not in any particular order.

[0068] As shown in the figure, step S300 includes the following steps:

[0069] S310: Asynchronous die cutting of the first composite product on a flat plate, so that the first composite product forms a third frame waste and a third hole material, the third hole material including an eighth product, an eighth double-sided adhesive and an eighth release film, the side of the third hole material with the eighth product falls onto the adhesive side of the first semi-finished product to form a second semi-finished product.

[0070] It is understandable that, in addition to the die-cutting process of the first composite product using a circular die-cutting tool, the required product can also be produced by asynchronous die-cutting with a flat die-cutting tool. For example, in this embodiment, the first composite product is asynchronously die-cut with a flat die-cutting tool to obtain the third frame waste and the third hole material falling on the first semi-finished product. The third hole material includes the eighth product, the eighth double-sided adhesive and the eighth release film. The side of the third hole material with the eighth product falls on the adhesive side of the first semi-finished product to form the second semi-finished product.

[0071] It should be understood that, in this embodiment, the eighth product is a flat-blade Mylar 800 die-cut from two irregularly shaped flat plates.

[0072] As shown in the figure, the steps preceding step S310 include the following:

[0073] S320: The side of the first semi-finished product covered with the second low-viscosity film 900 is laminated with the third low-viscosity film to form the thirteenth composite product;

[0074] S330: Die-cut the thirteenth composite product to form the fifth frame material and the first hole waste from the first semi-finished product;

[0075] S340: Remove the waste from the first hole to form the finished product, which has a positioning hole 910 for easy asynchronous die cutting of the flat plate.

[0076] It is understood that the steps preceding step S310 include the following: laminating a third low-adhesion film onto the side of the first semi-finished product with the second low-adhesion film 900 to form a thirteenth composite product; subsequently, die-cutting the first semi-finished product on the thirteenth composite product to form a first hole waste and a fifth frame material, removing the third low-adhesion film and the first hole waste, so that a fitting hole 910 is formed on the first semi-finished product, thereby facilitating fitting die-cutting through the fitting hole 910 in step S310 and improving the degree of alignment during die-cutting.

[0077] As shown in the figure, step S330 includes the following steps:

[0078] S331: Die-cutting the thirteenth composite product so that the first semi-finished product has a fifth frame material, a first hole waste and a second hole waste;

[0079] S332: Remove the waste from the second hole so that positioning holes 110 are formed on the first semi-finished product.

[0080] It is understood that step S330 includes the following steps: when die-cutting the thirteenth composite, the first semi-finished product is formed with the first hole waste, the second hole waste and the fifth frame material, and then the second hole waste is removed so that the positioning hole 110 is formed on the first semi-finished product, so that the final integrated part can be aligned with the product to be mounted through the positioning hole 110, thereby improving the mounting accuracy and preventing misalignment.

[0081] It should be understood that, in order to verify the alignment during the circular die-cutting in step S330 and the die-cutting in step S430, so that the second product can be located in the designated position on the first semi-finished product and the second frame material 700 is also located in the designated position on the third semi-finished product, a mark is usually cut out on the second low-adhesion film 900 of the first semi-finished product. Marks are also cut out during the die-cutting in steps S330 and S430 respectively. The relative positions of the three marks are confirmed by the visual positioning system. If the relative positions of the three marks are within the allowable error range, it proves that the alignment of the die-cutting in S330 and S430 meets the requirements. Otherwise, it is necessary to adjust the relative positions of the corresponding die-cutting according to the relative positions.

[0082] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
