Specifically, one side of the foam is attached to the bonding portion, and one side of the double-sided tape is attached to the side of the foam away from the bonding portion. The second die-cut structure is frame-shaped, that is, the second die-cut structure has a central hole; the handle is attached to the hand-tear portion, and the handle is formed by tape.
[0003] In the related art, the process of producing the above-mentioned die-cut products is as follows: compound foam and double-sided tape, cut out a center hole, cut out a handle position along the length of the material strip, that is, cut out the foam and double-sided tape corresponding to the hand-tear portion; then, compound a narrow tape and a release film corresponding to the handle position, and then cut out the product shape corresponding to the first die-cut structure, so that the foam and double-sided tape outer frame shape are cut out to form a second die-cut structure, and the tape is cut to form a handle, and the above-mentioned die-cut product is formed after the waste is discharged. The direction of the hand-tear portion of the first die-cut structure is defined as the forward direction. In the above-mentioned process, the first die-cut structure is distributed along the width direction of the material strip, that is, the handle is distributed in the width direction. The foam corresponding to the handle position needs to be cut off when the handle position is reached. Therefore, a large amount of foam will be cut off and discharged through the above-mentioned production process, resulting in foam waste. Summary of the Invention
[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a die-cutting process that can achieve the purpose of saving material in the process of producing a die-cut product.
[0005] According to an embodiment of the present application, a die-cutting process is used to produce a die-cut product, the die-cut product comprising a first die-cutting structure, a second die-cutting structure, and a handle; wherein the first die-cutting structure is formed by a release film, including a bonding portion and a hand-tear portion; the second die-cutting structure is formed by foam and double-sided tape, the second die-cutting structure being attached to the bonding portion, with one side of the foam attached to the bonding portion and one side of the double-sided tape attached to a side of the foam away from the bonding portion; the second die-cutting structure is frame-shaped, i.e., the second die-cutting structure has a central hole; the handle is attached to the hand-tear portion, and the handle is formed by tape, comprising:
[0006] The composite foam and the double-sided tape form a composite body;
[0007] Laminating a support film at the lower end of the composite body and performing a first die-cut, wherein the composite body is asynchronously die-cut so that the composite body is cut into a plurality of blocks distributed along the length direction of the support film, and the support film is die-cut so that through holes are formed at positions of the support film where the composite body is not laminated;
[0008] The adhesive tape and the process film are laminated under the base film and die-cut for the second time, wherein the die-cut is performed at the position corresponding to the block-shaped composite body to form a central hole in the composite body, and the die-cut is performed at the end of the through hole close to the central hole to form a cutting hole on the adhesive tape;
[0009] A release film is compounded on the upper end of the foam and a knife is inserted from one side of the release film for a third die-cutting, wherein die-cutting is performed at the position corresponding to the through hole to form the outline of the hand-tear portion on the tape, and the outline of the hand-tear portion combined with the cut hole enables the tape to form a handle; die-cutting is performed at the position corresponding to the composite body to form the outline of the fitting portion on the composite body, and the outline of the fitting portion combined with the center hole enables the composite body to form a second die-cut structure, and the outline of the fitting portion and the outline of the hand-tear portion enable the first die-cutting structure to be formed on the release film, thereby forming a die-cut product.
[0010] A die-cutting process according to an embodiment of the present application has at least the following beneficial effects:
[0011] After the first die-cutting, the composite is distributed on the base film along the length direction through asynchronous die-cutting. As a result, the base film has a portion compounded with the composite and a portion not compounded with the composite. A through hole is formed in the portion not compounded with the composite, and the subsequently compounded tape can be bonded to the release film through the through hole. Then, under the action of the cut hole and the contour of the hand-tear portion, the portion of the tape bonded to the release film forms a handle; in addition, a center hole is formed on the composite and the contour of the fitting portion is matched to form the composite to form a second die-cut structure; and since the third die-cutting is performed from one side of the release film, the contour of the hand-tear portion and the contour of the fitting portion form the first die-cut structure on the release film.
[0012] It can be understood that through the above-mentioned die-cutting process, the die-cut products are finally arranged along the length direction of the material strip, and the material saving effect can be achieved by asynchronous die-cutting of foam. Specifically, the first die-cutting structure only needs to be attached to the bonding part, that is, there is no need for foam at the position corresponding to the hand-tear part. By asynchronously die-cutting the composite body, the position corresponding to the hand-tear part does not have a composite body, and only the position of the bonding part has a composite body, thereby achieving the purpose of saving foam; in addition, through the above-mentioned die-cutting process, before the above-mentioned third die-cutting, the tape can be pre-attached to the release film through the through hole, and the composite body with a center hole can be attached to the release film. After the third die-cutting is completed, the handle formed by the tape and the second die-cutting structure formed by the composite body can be directly attached to the first die-cutting structure formed by the release film, without the need for additional transfer or composite processes, so that the position accuracy of the handle and the second die-cutting structure is accurate, and the finished product quality of the die-cut product is high.

[0015] According to some embodiments of the present application, during the process of forming the cutting hole, a knife is inserted from one side of the base film, passes through the cutting hole, and cuts through the adhesive tape and the process film.
[0016] According to some embodiments of the present application, in the process of forming the contour of the hand-tear portion, a knife is inserted from one side of the release film to cut through the release film, the base film, and the adhesive tape.
[0017] According to some embodiments of the present application, in the process of forming the contour of the fitting portion, a knife is inserted from one side of the release film to cut through the release film and the composite body.
[0018] According to some embodiments of the present application, after the third die-cutting is completed, a protective film is laminated on both sides of the die-cut product.
[0019] According to some embodiments of the present application, the tape is red, blue, or black.
[0020] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become obvious from the description below, or will be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Reference Figure 10 For a die-cut product 500, Figure 10 This is a three-dimensional diagram of the die-cut product 500, which includes a first die-cut structure 510, a second die-cut structure 520, and a handle 530; wherein the first die-cut structure 510 is formed by a release film 600, including a bonding portion 511 and a hand-tear portion 512; the second die-cut structure 520 is formed by foam 110 and double-sided tape 120, the second die-cut structure 520 is attached to the bonding portion 511, one side of the foam 110 is attached to the bonding portion 511, and one side of the double-sided tape 120 is attached to the side of the foam 110 away from the bonding portion 511, the second die-cut structure 520 is frame-shaped, that is, the second die-cut structure 520 has a center hole 521; the handle 530 is attached to the hand-tear portion 512, and the handle 530 is formed by the tape 300. Specifically, the die-cut product of the present application is used for protection during the production process of the camera. It is attached to the camera through double-sided tape 120, and the foam 110 and release film 600 are used to prevent the camera from being stuck with dust and bumps.
[0048] In the prior art, referring to Figures 11 to 13 , in order to produce the above die-cut product 500, the process is as follows: composite foam 110 and double-sided tape 120, refer to Figure 11 , cut out the center hole 521, refer to Figure 12 , cut out the handle 530 along the length direction of the material strip, that is, cut off the foam 110 and double-sided tape 120 corresponding to the hand-tear portion 512; then, the narrow tape 300 and the release film 600 are compounded at the position corresponding to the handle 530, and the Figure 13 Then, the product shape is cut out corresponding to the first die-cut structure 510, so that the outer frame shape of the foam 110 and the double-sided tape 120 is cut out to form the second die-cut structure 520, and the tape 300 is cut to form the handle 530. After the waste is discharged, the above-mentioned die-cut product 500 is formed. The direction of the hand-tear portion 512 of the first die-cut structure 510 is defined as the positive direction. In the above process, the first die-cut structure 510 is distributed along the width direction of the material strip, that is, the handle 530 is distributed in the width direction. The foam 110 corresponding to the position of the handle 530 needs to be cut when the handle 530 is in place. Therefore, the above production process cannot save material by asynchronously die-cutting the foam 110 first.
[0049] In order to produce the above die-cut product 500, refer to Figures 1 to 10 , the die-cutting process of this application includes:
[0050] The composite foam 110 and the double-sided tape 120 form a composite body 100;
[0051] The bottom support film 200 is compounded at the lower end of the composite body 100 and the first die cutting is performed.

Figure 2 Schematic diagram of the layered structure of the composite 100 and the base film 200 after the first die-cutting, wherein the composite 100 is asynchronously die-cut, so that the composite 100 is cut into multiple blocks distributed along the length direction of the base film 200, and the base film 200 is die-cut so that through holes 210 are formed at the positions of the base film 200 where the composite 100 is not laminated;
[0052] Under the bottom film 200, the adhesive tape 300 and the process film are laminated and die-cut for the second time. Figures 3 to 5 , Figure 3 This is the knife line diagram formed by the second die cutting. Figure 4 The knife line diagram formed by the first die cutting and the second die cutting, Figure 5 Schematic diagram of the layered structure of the composite body 100, the base film 200, the adhesive tape 300, and the process film after the second die-cutting. The die-cutting is performed at the position corresponding to the block-shaped composite body 100 to form a center hole 521 in the composite body 100. Furthermore, the die-cutting is performed at the end of the through hole 210 close to the center hole 521 to form a cut-off hole 310 in the adhesive tape 300.
[0053] The release film 600 is laminated on the upper end of the foam 110 and the third die-cut is performed from one side of the release film 600. Figures 6 to 9 , Figure 6 This is the knife line diagram formed by the third die cutting.

Figure 9 for Figure 8 Schematic diagram of the layered structure after waste discharge, wherein die-cutting is performed at the position corresponding to the through hole 210 to form the outline of the hand-tear portion 512 on the tape 300 (the outline of the hand-tear portion 512 is defined as the first outline 320), and the outline of the hand-tear portion 512 is combined with the cut-off hole 310 to form a handle 530 on the tape 300; die-cutting is performed at the position corresponding to the composite 100 to form the outline of the bonding portion 511 on the composite 100 (the outline of the bonding portion 511 is defined as the second outline 330 process film 400), and the outline of the bonding portion 511 is combined with the center hole 521 to form the second die-cut structure 520 on the composite 100, and the outline of the bonding portion 511 and the outline of the hand-tear portion 512 form the first die-cut structure 510 on the release film 600, refer to Figure 9 and Figure 10 , forming a die-cut product 500.
[0054] A die-cutting process according to an embodiment of the present application has at least the following beneficial effects:
[0055] After the first die-cutting, the composite 100 is asynchronously die-cut so that the composite 100 is distributed on the base film 200 along the length direction. As a result, the base film 200 has a portion compounded with the composite 100 and a portion not compounded with the composite 100. A through hole 210 is formed in the portion not compounded with the composite 100, and the subsequently compounded tape 300 can be bonded to the release film 600 through the through hole 210. Then, under the action of the cut hole 310 and the contour of the hand-tear portion 512, the portion of the tape 300 bonded to the release film 600 forms a handle 530; in addition, a center hole 521 is formed on the composite 100 and the contour of the fitting portion 511 is matched to form the second die-cutting structure 520 of the composite 100; and since the third die-cutting is performed from one side of the release film 600, the contour of the hand-tear portion 512 and the contour of the fitting portion 511 form the first die-cutting structure 510 on the release film 600.
[0056] It is understandable that, referring to Figure 7 Through the above die-cutting process, the die-cut products 500 are finally arranged along the length direction of the material strip, and the asynchronous die-cutting foam 110 can achieve the effect of saving material. Specifically, the first die-cut structure 510 only needs to be attached to the bonding portion 511, that is, the position corresponding to the hand-tear portion 512 does not need to have the foam 110. Through the asynchronous die-cutting method of the composite body 100, the position corresponding to the hand-tear portion 512 does not have the composite body 100, and only the position of the bonding portion 511 has the composite body 100, thereby achieving the purpose of saving foam 110; in addition, through the above die-cutting process, Before the third die-cutting, the tape 300 can be pre-attached to the release film 600 through the through hole 210, and the composite body 100 with the center hole 521 can be attached to the release film 600. After the third die-cutting is completed, the handle 530 formed by the tape 300 and the second die-cut structure 520 formed by the composite body 100 can be directly attached to the first die-cut structure 510 formed by the release film 600 without the need for additional transfer or compounding processes, so that the position accuracy of the handle 530 and the second die-cut structure 520 is accurate, and the finished product quality of the die-cut product 500 is high.
[0057] According to some embodiments of the present application, referring to Figure 4 and Figure 5 , the outline of the cut-off hole 310 partially overlaps with the outline of one end of the through hole 210 close to the center hole 521 .
[0058] It is understood that the through hole 210 corresponds to the size of the tape 300 that can be attached to the release film 600. Figure 7The contours of the cutting hole 310 and the hand-tear portion 512 cooperate to form the contour of the hand-tear portion 512. In order to ensure that the handle 530 is a separate strip compounded on the release film 600, the contour of the cutting hole 310 overlaps with the contour of the end of the through hole 210 near the center hole 521. Figure 8 and Figure 9 , ensuring that the portion of the tape 300 within the outline of the hand-tear portion 512 is a continuous strip.
[0059] According to some embodiments of the present application, referring to Figure 5 In the process of forming the center hole 521, the knife is inserted from one side of the composite body 100 and cuts through the base film 200, the tape 300, and the process film.
[0060] It is understandable that this is done to facilitate the drainage of waste.
[0061] According to some embodiments of the present application, referring to Figure 5 In the process of forming the cutting hole 310, the knife is inserted from one side of the base film 200, passes through the cutting hole 310 and cuts through the tape 300 and the process film.
[0062] It is understandable that this is done to facilitate the drainage of waste.
[0063] According to some embodiments of the present application, in the process of forming the outline of the hand-tear portion 512 , a knife is inserted from one side of the release film 600 to cut through the release film 600 , the bottom film 200 , and the tape 300 .
[0064] It is understandable that the handle 530 is formed by the tape 300 and only the tape 300 needs to be cut.
[0065] According to some embodiments of the present application, during the process of forming the contour of the fitting portion 511 , a knife is inserted from one side of the release film 600 to cut through the release film 600 and the composite body 100 .
[0066] It can be understood that the second die-cut structure 520 is formed by the composite body 100 and only needs to be cut into the composite body 100 .
[0067] According to some embodiments of the present application, after the third die-cutting is completed, a protective film is laminated on both sides of the die-cut product 500 .
[0068] It is understandable that this is to prevent the die-cut product 500 from being contaminated by dust during its later transportation and shipment.
[0069] According to some embodiments of the present application, the tape 300 is red, blue, or black.
[0070] It is understandable that the die-cut product 500 is relatively small in size and is not easy to find after being attached for use. The tape 300 is set to be non-transparent so that the handle 530 and the die-cut product 500 can be easily seen.
[0071] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
