Description

Technical Field

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

[0002] In some manufacturing processes, parts require the attachment of die-cut products. A robotic arm is equipped with multiple suction cups to pick up multiple die-cut products at once and attach them to the parts. In related technologies, the arrangement of the parts is fixed, and the arrangement of the suction cups on the robotic arm is consistent with the arrangement of the parts. Furthermore, to facilitate attachment of the die-cut products, the spacing between the parts is relatively large, consequently, the spacing between the suction cups on the robotic arm is also relatively large. To ensure that all suction cups on the robotic arm can pick up the corresponding die-cut products, the arrangement of the die-cut products is consistent with the arrangement of the suction cups on the robotic arm. Therefore, the spacing between the die-cut products is also relatively large. During the die-cutting process, the material strip corresponding to the gaps between the die-cut products is treated as waste and discharged. Thus, due to the large spacing between the die-cut products, a significant amount of material strip is discharged, resulting in substantial material waste. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a die-cutting process that can improve the utilization rate of the strip material.

[0004] The die-cutting process according to the embodiments of this application includes the following steps:

[0005] A first semi-finished product and a second semi-finished product are formed on a first composite strip. A plurality of first semi-finished products are connected along the x-axis and spaced apart along the y-axis. A plurality of second semi-finished products are connected along the x-axis and spaced apart along the y-axis. Each first semi-finished product and each second semi-finished product are symmetrically arranged.

[0006] A third semi-finished product is formed on the second composite strip;

[0007] The first composite strip and the second composite strip are combined to bond the first semi-finished product and the third semi-finished product together;

[0008] The first composite strip, having lost the first semi-finished product, is combined with another second composite strip to bond the second semi-finished product and the third semi-finished product on the other second composite strip.

[0009] The die-cut product according to the embodiments of this application has at least the following beneficial effects: A second semi-finished product is formed by the spacing between first semi-finished products distributed along the y-axis direction, and the second and first semi-finished products are symmetrically arranged. After the first composite strip is flipped, the arrangement positions of the second and first semi-finished products overlap. Thus, the first semi-finished products on the first composite strip and the third semi-finished products on the second composite strip are bonded together, and through subsequent further die-cutting, a first set of die-cut products can be formed, and the first composite strip that has lost its first semi-finished products is recovered. The first composite strip that has lost its first semi-finished products is unwound and flipped so that the second semi-finished product moves to a position corresponding to the third semi-finished product on another second composite strip, and the second semi-finished product is bonded to the third semi-finished product on the other second composite strip. It should be understood that a first semi-finished product and a second semi-finished product are simultaneously formed on the first composite strip, so as to form a second semi-finished product by utilizing the interval between adjacent first semi-finished products. Since the first semi-finished products and the second semi-finished products are symmetrically arranged, the arrangement of the first semi-finished products and the second semi-finished products is rotationally symmetrical. Both the first semi-finished products and the second semi-finished products can be used to form die-cut products with the third semi-finished product, thereby improving the utilization rate of the first composite strip and reducing the waste of the first composite strip.

[0023] The breathable membrane is laminated on the side of the second double-sided adhesive away from the second base material strip;

[0024] Flip the second bottom support strip so that it is above the first bottom support strip, with the side of the second double-sided adhesive with the breathable membrane facing the side of the first double-sided adhesive away from the first bottom support strip;

[0030] According to some embodiments of this application, die-cutting the first composite strip includes the following steps:

[0031] A first cutting line, a second cutting line, and a first dividing line are formed on the first composite strip. The first cutting line and the second cutting line are symmetrically arranged with the first dividing line as the line of symmetry. The first cutting line and the first dividing line enclose a plurality of first through holes distributed along the x-axis direction to form a plurality of first semi-finished products distributed along the x-axis direction between the first cutting line and the first dividing line. The second cutting line and the first dividing line enclose a plurality of second through holes distributed along the x-axis direction to form a plurality of second semi-finished products distributed along the x-axis direction between the second cutting line and the first dividing line.

[0045] The third double-sided adhesive and the PET film are die-cut to form a third cutting line and a second dividing line. The third cutting line and the second dividing line enclose a plurality of third through holes and a fourth through hole distributed along the x-axis direction, so as to form a plurality of composites distributed along the x-axis direction between the third cutting line and the second dividing line.

[0046] Multiple sets of the third cutting lines and the second dividing lines are formed along the y-axis direction to form multiple composites in the y-axis direction;

[0080] Reference Figures 1 to 13 The embodiments of this application provide a die-cutting process, which includes the following steps:

[0081] A first semi-finished product 110 and a second semi-finished product 120 are formed on the first composite strip 100. A plurality of first semi-finished products 110 are connected along the x-axis direction and spaced apart along the y-axis direction. A plurality of second semi-finished products 120 are connected along the x-axis direction and spaced apart along the y-axis direction. Each first semi-finished product 110 and a second semi-finished product 120 are symmetrically arranged.

[0082] A third semi-finished product 410 is formed on the second composite strip 400;

[0083] The first composite strip 100 and the second composite strip 400 are combined to make the first semi-finished product 110 and the third semi-finished product 410 adhere together;

[0084] The first composite strip 100, which loses the first semi-finished product 110, is combined with another second composite strip 400 to make the second semi-finished product 120 and the third semi-finished product 410 on the other second composite strip 400 adhere together.

[0085] It is understood that the intervals between the first semi-finished products 110 distributed along the y-axis form the second semi-finished product 120, and the second semi-finished product 120 and the first semi-finished product 110 are symmetrically arranged. After the first composite strip 100 is flipped, the arrangement position of the second semi-finished product 120 overlaps with the arrangement position of the first semi-finished product 110. Thus, the first semi-finished product 110 on the first composite strip 100 and the third semi-finished product 410 on the second composite strip 400 are bonded together, and through subsequent die-cutting, a first set of die-cut products can be formed, and the first composite strip 100 that has lost the first semi-finished product 110 is recycled. The first composite strip 100 that has lost the first semi-finished product 110 is unwound and flipped so that the second semi-finished product 120 moves to the position corresponding to the third semi-finished product 410 on another second composite strip 400, and the second semi-finished product 120 is bonded to the third semi-finished product 410 on another second composite strip 400. It should be understood that a first semi-finished product 110 and a second semi-finished product 120 are simultaneously formed on the first composite strip 100, so as to utilize the interval between adjacent first semi-finished products 110 to form the second semi-finished product 120. Since the first semi-finished products 110 and the second semi-finished products 120 are symmetrically arranged, the arrangement of the first semi-finished products 110 and the second semi-finished products 120 is rotationally symmetrical. Both the first semi-finished products 110 and the second semi-finished products 120 can be used to composite with the third semi-finished product 410 to form a die-cut product. This improves the utilization rate of the first composite strip 100, reduces the waste of the first composite strip 100, and especially improves the utilization rate of the breathable membrane 250.

[0086] Specifically, the die-cutting process of this application is used to produce a die-cut product, referring to... Figure 14 The die-cut product includes a first film 610, a breathable sheet 620, a second film 630, a PET sheet 640, a third film 650, and Mylar 660, which are sequentially laminated. The first film 610 has a first through-hole 611, the second film 630 has a second through-hole 631, the third film 650 has a third through-hole 651, and the PET sheet 640 has a fourth through-hole 641. The first semi-finished product 110 and the second semi-finished product 120 each have the first film 610, the breathable sheet 620, and the second film 630 respectively. The third semi-finished product 410 has the PET sheet 640, the third film 650, and the Mylar 660 respectively. When the first semi-finished product 110 or the second semi-finished product 120 is laminated, the side of the second film 630 away from the breathable sheet 620 can be laminated with the side of the PET sheet 640 away from the third film 650.

[0087] It should be noted that, in order to ensure the rotational symmetry of the distribution of the first semi-finished product 110 and the second semi-finished product 120, the distances of the first semi-finished product 110 and the second semi-finished product 120 along the y-axis are consistent, as are the distances along the x-axis.

[0088] Specifically, the first composite strip 100 and the second composite strip 400 extend along the x-axis direction. The first semi-finished product 110, the second semi-finished product 120, and the third semi-finished product 410 distributed along the x-axis direction are connected by a waste portion to facilitate the conveying and winding of the first semi-finished product 110, the second semi-finished product 120, and the third semi-finished product 410 distributed along the x-axis direction. After the first composite strip 100 and the second composite strip 400 are composited, two adjacent first semi-finished products 110, two adjacent second semi-finished products 120, and two adjacent third semi-finished products 410 can be die-cut to separate the first semi-finished product 110, the second semi-finished product 120, and the third semi-finished product 410.

[0089] Specifically, the x-axis direction is the length direction of the material strip, and the y-axis direction is the width direction of the material strip.

[0090] It should be noted that the distribution distance of the first semi-finished product 110 and the third semi-finished product 410 formed above is the same as the distribution distance of the suction cups on the robotic arm used to grasp the die-cut products, thereby enabling the robotic arm to grasp multiple die-cut products at one time.

[0091] Reference Figures 1 to 6 According to some embodiments of this application, forming a first semi-finished product 110 and a second semi-finished product 120 on a first composite strip 100 includes the following steps:

[0092] A first double-sided adhesive 220 and a second double-sided adhesive 230 are laminated onto the bottom material strip 210, and the first double-sided adhesive 220 and the second double-sided adhesive 230 are distributed along the y-axis direction;

[0093] The first process release film 240 is laminated and covers the side of the first double-sided adhesive 220 and the second double-sided adhesive 230 away from the base material strip 210;

[0094] Die-cut a first double-sided adhesive 220 and a second double-sided adhesive 230. A plurality of first through holes 611 distributed along the x-axis and along the y-axis are formed on the first double-sided adhesive 220. A plurality of second through holes 631 distributed along the x-axis and along the y-axis are formed on the second double-sided adhesive 230. The distribution distance of the first through holes 611 and the second through holes 631 is the same.

[0095] Separate the first double-sided adhesive 220 and the second double-sided adhesive 230, so that the bottom support strip 210 and the first process release film 240 are both cut into two strips. Each bottom support strip 210 and each first process release film 240 are respectively bonded with the first double-sided adhesive 220 or the second double-sided adhesive 230. The bottom support strip 210 bonded with the first double-sided adhesive 220 is defined as the first bottom support strip 211, and the bottom support strip 210 bonded with the second double-sided adhesive 230 is defined as the second bottom support strip 212.

[0096] The breathable membrane 250, the first double-sided adhesive 220, and the second double-sided adhesive 230 are combined so that the two sides of the breathable membrane 250 are respectively bonded to the side of the first double-sided adhesive 220 and the second double-sided adhesive 230 away from the bottom material strip 210 to form the first composite material strip 100.

[0097] Die-cut the first composite strip 100.

[0098] Understandably, the support strip 210 simultaneously carries the first double-sided adhesive 220 and the second double-sided adhesive 230 to facilitate transport. Then, a first through-hole 611 corresponding to the first film 610 is formed on the first double-sided adhesive 220, and a second through-hole 631 corresponding to the second film 630 is formed on the second double-sided adhesive 230. Subsequently, the support strip 210 is cut to form the first support strip 211 and the second support strip 212 to transport the first double-sided adhesive 220 and the second double-sided adhesive 230 respectively, facilitating the lamination of the first and second double-sided adhesives 220 and 230 onto both sides of the breathable membrane 250. When the first and second double-sided adhesives 220 and 230 are lamination on both sides of the breathable membrane 250, the positions of the first through-hole 611 and the second through-hole 631 correspond one-to-one. After the first double-sided adhesive 220 and the second double-sided adhesive 230 are laminated on both sides of the breathable membrane 250, the first composite strip 100 is die-cut to form the shape corresponding to the first film 610, the breathable sheet 620 and the second film 630, thereby forming the first film 610 with the first through hole 611, the breathable sheet 620 without the through hole and the second film 630 with the second through hole 631.

[0099] Reference Figure 5 and Figure 6 According to some embodiments of this application, die-cutting the first double-sided adhesive 220 and the second double-sided adhesive 230 includes the following steps:

[0100] Two sets of first positioning holes and two sets of second positioning holes distributed along the x-axis are formed on the base material strip 210. The two sets of first positioning holes are distributed along the y-axis on both sides of the first double-sided adhesive 220, and the two sets of second positioning holes are distributed along the y-axis on both sides of the second double-sided adhesive 230. The distance between adjacent first positioning holes in the same group is the same as the distance between adjacent second positioning holes in the same group.

[0101] It is understandable that the first positioning hole and the second positioning hole are simultaneously die-cut when the first through hole 611 and the second through hole 631 are die-cut. After the base material strip 210 is cut to form the first base material strip 211 and the second base material strip 212, the first positioning hole is located in the first base material strip 211, and the second positioning hole is located in the second base material strip 212, and the distribution distance of the first through hole 611 and the second through hole 631 is consistent. Therefore, during the process of the first double-sided adhesive 220 and the second double-sided adhesive 230 being laminated on both sides of the breathable membrane 250, the positioning post passes through the first positioning hole and the corresponding second positioning hole to ensure that the positions of the first through hole 611 on the first double-sided adhesive 220 and the second through hole 631 on the second double-sided adhesive 230 correspond, ensuring that the positions of the first through hole 611 on the subsequently formed first film 610 and the second through hole 631 on the second film 630 correspond, thus ensuring the positional accuracy of the first film 610 and the second film 630.

[0102] Specifically, the first semi-finished product 110 and the second semi-finished product 120 are distributed at the same distance along the y-axis. When the number of the first semi-finished product 110 and the second semi-finished product 120 distributed along the y-axis is odd, the two sets of first positioning holes / two sets of second positioning holes are symmetrical about the line of symmetry between the first semi-finished product 110 and the second semi-finished product 120 located in the middle. When the number of the first semi-finished product 110 and the second semi-finished product 120 distributed along the y-axis is multiple, the two sets of first positioning holes / two sets of second positioning holes are symmetrical about the line of symmetry between the first semi-finished product 110 and the second semi-finished product 120 located on the outermost part of the first semi-finished product 110 and the second semi-finished product 120 along the y-axis on the first composite strip 100. Thus, after rotating the first composite strip 100, the positions of the two sets of first positioning holes / two sets of second positioning holes are interchanged and can overlap. It should be noted that a third positioning hole is formed on the second composite strip 400, which is distributed in the same way as the first / second positioning holes. During the process of bonding the first semi-finished product 110 / second semi-finished product 120 and the third semi-finished product 410, the first, second, and third positioning holes correspond, and the positioning post passes through them to improve the accuracy of the bonding between the first / second semi-finished product 110 / second semi-finished product 120 and the third semi-finished product 410. Furthermore, since the two sets of first positioning holes / two sets of second positioning holes are rotationally symmetrical, the positions of the first / second positioning holes are the same during the bonding of the first semi-finished product 110 and the third semi-finished product 410 on the second composite strip 400, and during the bonding of the second semi-finished product 120 and the third semi-finished product 410 on another second composite strip 400. Therefore, the first / second positioning holes can be shared during the bonding of the first semi-finished product 110 and the second semi-finished product 120.

[0103] Reference Figure 1 and Figure 4According to some embodiments of this application, the composite breathable membrane 250, the first double-sided adhesive 220, and the second double-sided adhesive 230 include the following steps:

[0104] A dustproof tape 260 is laminated on one side of the first process release film 240 laminated with the first double-sided adhesive 220 and on the other side of the first process release film 240 laminated with the second double-sided adhesive 230.

[0105] A process dustproof film 270 is laminated on the side of the first bottom material strip 211 away from the first double-sided adhesive 220 and the side of the second bottom material strip 212 away from the second double-sided adhesive 230.

[0106] Remove the first-process release film 240 and dustproof tape 260 from the second double-sided adhesive 230;

[0107] A breathable membrane 250 is laminated on the side of the second double-sided adhesive 230 away from the second base material strip 212;

[0108] Flip the second bottom support strip 212 so that it is above the first bottom support strip 211, and the side of the second double-sided adhesive 230 with the breathable membrane 250 faces the side of the first double-sided adhesive 220 away from the first bottom support strip 211.

[0109] Remove the first process release film 240 and dustproof tape 260 from the first double-sided adhesive 220;

[0110] The first double-sided adhesive 220 is on the side away from the first base material strip 211 and the breathable membrane 250 is on the side away from the second double-sided adhesive 230.

[0111] It is understandable that, since the first double-sided adhesive 220, the first process release film 240, the first base material tape 211, the second double-sided adhesive 230, and the second base material tape 212 all have a first through hole 611 or a second through hole 631, in order to prevent dust from entering the first through hole 611 or the second through hole 631, a dustproof tape 260 is respectively laminated on the side of the first process release film 240 laminated with the first double-sided adhesive 220 and the side of the first process release film 240 laminated with the second double-sided adhesive 230. In addition, a process dustproof film 270 is respectively laminated on the side of the first base material tape 211 away from the first double-sided adhesive 220 and the side of the second base material tape 212 away from the second double-sided adhesive 230. The dustproof tape 260 and the process dustproof film 270 cover the first through hole 611 and the second through hole 631, thereby playing a dustproof role. Subsequently, after the second double-sided adhesive 230 is in place, the first process release film 240 and the breathable film 250 on the second double-sided adhesive 230 are removed to allow the second double-sided adhesive 230 to protrude, and then it is laminated with the breathable film 250. To attach the second double-sided adhesive 230 and the second double-sided adhesive 230 to both sides of the breathable film 250, the second backing strip 212 is first flipped over, positioned above the first backing strip 211, with the side of the second double-sided adhesive 230 with the breathable film 250 facing the first double-sided adhesive 220. Next, the first process release film 240 and the dustproof tape 260 on the first double-sided adhesive 220 are removed to allow the first double-sided adhesive 220 to protrude, and then the breathable film 250 and the first double-sided adhesive 220 are laminated, so that the first double-sided adhesive 220 and the second double-sided adhesive 230 are respectively located on both sides of the breathable film 250.

[0112] Reference Figure 1 and Figure 4 According to some embodiments of this application, the composite breathable membrane 250, the first double-sided adhesive 220, and the second double-sided adhesive 230 further include the following steps:

[0113] Remove the second bottom material strip 212 and two process dustproof films 270;

[0114] A first process backing film is laminated on the side of the first backing material strip 211 away from the first double-sided adhesive 220, and a second process release film 290 is laminated on the side of the second double-sided adhesive 230 away from the breathable film 250 to form a first composite material strip 100.

[0115] Understandably, the process dustproof film 270 and dustproof tape 260 are relatively soft, which is not conducive to subsequent die-cutting. Therefore, the second base material tape 212 and the two process dustproof films 270 are discarded, and the first process base film is laminated on the side of the first base material tape 211 away from the first double-sided adhesive 220. The second process release film 290 is laminated on the side of the second double-sided adhesive 230 away from the breathable film 250, forming the first composite material tape 100, so that the first process base film is attached to the side of the first base material tape 211 away from the first double-sided adhesive 220, and the second process release film 290 is attached to the side of the second double-sided adhesive 230 away from the breathable film 250.

[0116] Reference Figure 1 , Figure 5 and Figure 6 According to some embodiments of this application, die-cutting the first composite strip 100 includes the following steps:

[0117] A first cutting line 310, a second cutting line 320, and a first dividing line 330 are formed on the first composite strip 100. The first cutting line 310 and the second cutting line 320 are symmetrically arranged with the first dividing line 330 as the line of symmetry. The first cutting line 310 and the first dividing line 330 enclose a plurality of first through holes 611 distributed along the x-axis direction to form a plurality of first semi-finished products 110 distributed along the x-axis direction between the first cutting line 310 and the first dividing line 330. The second cutting line 320 and the first dividing line 330 enclose a plurality of second through holes 631 distributed along the x-axis direction to form a plurality of second semi-finished products 120 distributed along the x-axis direction between the second cutting line 320 and the first dividing line 330.

[0118] Multiple sets of first cutting lines 310, second cutting lines 320 and first dividing lines 330 are formed along the y-axis direction so that the first composite strip 100 forms multiple first semi-finished products 110 and multiple second semi-finished products 120 along the y-axis direction.

[0119] Understandably, the first cutting line 310 and the first dividing line 330 cause the first double-sided adhesive 220, the second double-sided adhesive 230, and the breathable film 250 to respectively form the shapes of the first film 610, the second film 630, and the breathable sheet 620, and cooperate with the previously formed first through hole 611 and second through hole 631 to form the first semi-finished product 110, and the first semi-finished product 110 is connected along the x-axis direction. Similarly, the second cutting line 320 and the first dividing line 330 cause the first double-sided adhesive 220, the second double-sided adhesive 230, and the breathable film 250 to respectively form the shapes of the first film 610, the second film 630, and the breathable sheet 620, and cooperate with the previously formed first through hole 611 and second through hole 631 to form the second semi-finished product 120, and the second semi-finished product 120 is connected along the x-axis direction. Furthermore, the first cutting line 310 and the second cutting line 320 are symmetrical about the first dividing line 330, thereby making the first semi-finished product 110 and the second semi-finished product 120 symmetrical. At the same time, by forming multiple sets of first cutting lines 310, second cutting lines 320 and first dividing lines 330 along the y-axis direction, the first composite strip 100 forms multiple spaced first semi-finished products 110 and multiple spaced second semi-finished products 120 along the y-axis direction.

[0120] Reference Figure 5 and Figure 6 According to some embodiments of this application, die-cutting the first composite strip 100 includes the following steps:

[0121] The first dividing line 330 distributed along the y-axis divides the second process release film 290, so that the second process release film 290 is divided into multiple strips along the y-axis. Part of the second process release film 290 covers the first semi-finished product 110, and part of the second process release film 290 covers the second semi-finished product 120.

[0122] Exclude the second-process release film 290 covering the first semi-finished product 110;

[0123] The third process release film 291 is composited and covers the side of the second process release film 290 away from the second semi-finished product 120 and the side of the first semi-finished product 110.

[0124] Understandably, the first dividing line 330 extends along the x-axis, and multiple sets of first dividing lines 330 divide the second process release film 290 into multiple strips. Since the first semi-finished product 110 and the second semi-finished product 120 are symmetrical about the first dividing line 330, the multiple second process release films 290 formed by the multiple first dividing lines 330 will be partially laminated onto the first semi-finished product 110 and partially laminated onto the second semi-finished product 120. Subsequently, the second process release film 290 covering the first semi-finished product 110 is removed to allow the first semi-finished product 110 to be exposed. Then, a third process release film 291 is laminated so that the third process release film 291 covers both the second process release film 290 and the first semi-finished product 110, thereby protecting the first semi-finished product 110. The third process release film 291 can be removed when using the first semi-finished product 110, while the second semi-finished product 120 is still protected by the second process release film 290. When the second semi-finished product 120 is needed, the second process release film 290 on the second semi-finished product 120 can be removed.

[0125] Specifically, in the third process, the release film 291 is applied to the second double-sided adhesive 230 of the first semi-finished product 110.

[0126] Reference Figure 1 and Figure 13 According to some embodiments of this application, the composite material strip 100 and the composite material strip 400 are composited, including the following steps:

[0127] Remove the release film 291 of the third process, so that the second double-sided adhesive 230 on the first semi-finished product 110 is exposed, and the second double-sided adhesive 230 on the first semi-finished product 110 is bonded to the third semi-finished product 410;

[0128] The first composite strip 100, which has lost the first semi-finished product 110, is laminated with another second composite strip 400, including the following steps:

[0129] Remove the second process release film 290 covering the second semi-finished product 120, so that the second double-sided adhesive 230 on the second semi-finished product 120 is exposed, and the second double-sided adhesive 230 on the second semi-finished product 120 is bonded to the third semi-finished product 410 on another second composite material strip 400.

[0130] Understandably, when it is necessary to laminate the first composite strip 100 and the second composite strip 400, the third process release film 291 is first removed to expose the second double-sided adhesive 230 on the first semi-finished product 110. The second double-sided adhesive 230 on the first semi-finished product 110 adheres to the third semi-finished product 410. However, since the second semi-finished product 120 is protected by the second process release film 290, the second semi-finished product 120 will not adhere to the second composite strip 400. Then, the first composite strip 100 is wound up. When it is necessary to laminate the first composite strip 100 and another second composite strip 400, the second process release film 290 on the second semi-finished product 120 is removed to expose the second double-sided adhesive 230 on the second semi-finished product 120. The second double-sided adhesive 230 on the second semi-finished product 120 adheres to the third semi-finished product 410 on the other second composite strip 400.

[0131] Reference Figures 7 to 12 According to some embodiments of this application, forming a third semi-finished product 410 on the second composite strip 400 includes the following steps:

[0132] Composite PET film 510 and third double-sided adhesive 520;

[0133] Die-cut the third double-sided adhesive 520 and the PET film 510, and form a plurality of third through holes 651 distributed along the x-axis and along the y-axis on the third double-sided adhesive 520. Form a fourth through hole 641 corresponding to the third through hole 651 on the PET film 510. The distribution distance of the third through hole 651 and the first through hole 611 is the same.

[0134] Die-cut the third double-sided adhesive 520 and PET film 510 to form a third cutting line 340 and a second dividing line 350. The third cutting line 340 and the second dividing line 350 enclose a plurality of third through holes and fourth through holes distributed along the x-axis direction, so as to form a plurality of composites 421 distributed along the x-axis direction between the third cutting line 340 and the second dividing line 350.

[0135] Multiple sets of third cutter lines 340 and second dividing lines 350 are formed along the y-axis direction to form multiple composites 421 in the y-axis direction;

[0136] On the side of the third double-sided adhesive 520 away from the PET film 510, a release film 530 is laminated and die-cut into product 600;

[0137] Die-cut composite release film 530 and die-cut product 600, so that PET film 510 forms Mylar 660 corresponding one-to-one with composite 421.

[0138] It is understood that the composite PET film 510 and the third double-sided adhesive 520 form part of the second composite strip 400. The second composite strip 400 may also be laminated with other film materials on the side of the PET film 510 away from the third double-sided adhesive 520 and on the side of the third double-sided adhesive 520 away from the PET film 510, in order to facilitate transport and die-cutting. Subsequently, the PET film 510 and the third double-sided adhesive 520 are die-cut to form a fourth through hole 641 corresponding to the PET sheet 640 on the PET film 510 and a third through hole 651 corresponding to the third film 650 on the third double-sided adhesive 520. The third through hole 651 and the fourth through hole 641 correspond one-to-one, and the distribution distance of the third through hole 651 / fourth through hole 641 is consistent with the distribution distance of the first through hole 611 / second through hole 631. This ensures that after the first semi-finished product 110 / second semi-finished product 120 and the third semi-finished product 410 are bonded together, the positions of the first through hole 611, second through hole 631, third through hole 651 and fourth through hole 641 correspond, thereby improving the positional accuracy between the first film 610, second film 630, third film 650 and PET sheet 640 of the die-cut product. After forming the third through-hole 651 and the fourth through-hole 641, the third cutting line 340 and the second dividing line 350 cause the third double-sided adhesive 520 and the PET film 510 to respectively form the shapes of the third film 650 and the PET sheet 640, and cooperate with the previously formed third through-hole 651 and fourth through-hole 641 to form a composite 421 including the third film 650 and the PET sheet 640, and connect the third film 650 and the PET sheet 640 along the x-axis direction, so that the composite 421 is connected along the x-axis direction. At the same time, by forming multiple sets of third cutting lines 340 and second dividing lines 350 along the y-axis direction, the second composite strip 400 forms multiple spaced composites 421 along the y-axis direction.

[0139] After forming composite 421, a release film 530 die-cut product 600 is laminated on the side of the third double-sided adhesive 520 away from the PET film 510. It should be understood that the release film 530 die-cut product 600 also constitutes part of the second composite strip 400. Then, by die-cutting the release film 530 die-cut product 600, its shape is formed to correspond to the shape of the Mylar 660, thus forming the Mylar 660. The Mylar 660 corresponds one-to-one with composite 421, allowing the Mylar 660 to adhere to the third film 650 of composite 421, thereby forming the third semi-finished product 410. Specifically, the Mylar 660s are connected along the x-axis for easy transport and spaced apart along the y-axis to correspond to the distribution of composite 421.

[0140] Reference Figure 13 and Figure 14 According to some embodiments of this application, the die-cutting process further includes the following steps:

[0141] The first semi-finished product 110 or the second semi-finished product 120 is bonded to the third semi-finished product on the second composite strip 400 to form the third composite strip;

[0142] Die-cut the third composite strip to separate the composite 421 and Mylar 660 distributed along the x-axis, and to separate the first semi-finished product 110 or the second semi-finished product 120 distributed along the x-axis, so that the first semi-finished product 110, the second semi-finished product 120 and the third semi-finished product 410 form the shape of the corresponding finished product.

[0143] Understandably, after the first composite strip 100 and the second composite strip 400 are laminated, the first semi-finished product 110 or the second semi-finished product 120 is bonded to the third semi-finished product 410 on the second composite strip 400 to form the third composite strip. Specifically, the second film 630 on the first semi-finished product 110 / second semi-finished product 120 and the PET sheet 640 on the third semi-finished product 410 are bonded together, thereby forming the first film 610, the breathable sheet 620, the second film 630, the PET sheet 640, the third film 650, and the Mylar 660 bonded sequentially from top to bottom. At the same time, the first composite strip 100, which loses the first semi-finished product 110 or the second semi-finished product 120, is wound up. Then, the third composite strip is die-cut to cut the first semi-finished product 110, the second semi-finished product 120 and the third semi-finished product 410 distributed along the x-axis direction, so as to separate the first semi-finished product 110, the second semi-finished product 120 and the third semi-finished product 410 distributed along the x-axis direction to form a plurality of individual die-cut products 600.

[0144] 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.
