[0066] S410, reference Figure 6 The lower half and Figure 7 The first portion 210 is die-cut for the second time to form a first half-cut line 810 on the screen layer 400 and the first double-sided tape 300. The first half-cut line 810 corresponds to a partial outline of the first adhesive block 110 and the screen 120.

[0067] S510, reference Figure 8 The lower half and Figure 9The right half of the first part 210 is die-cut for the third time to form a second half-cut line 820 on the screen layer 400 and the first double-sided tape 300, and the second half-cut line 820 corresponds to the partial outline of the first glue block 110 and the screen 120; and the second half-cut line 820 and the first half-cut line 810 cooperate to form the first glue block 110 and the screen 120 on the screen layer 400 and the first double-sided tape 300 layer respectively.

[0068] It is understood that the combination of the screen 120 and the first adhesive block 110 is defined as a first semi-finished product, and the screen layer 400 and the first double-sided adhesive tape 300 are used to form the screen 120 and the first adhesive block 110, respectively. The first die-cutting of the first portion 210 in step S220 enables the first double-sided adhesive tape 300 to form the first through hole 110a in the first adhesive block 110. The second die-cutting of the first portion 210 in step 410 and the third die-cutting of the first portion 210 in step 510 enable the screen layer 400 and the first double-sided adhesive tape 300 to form the shapes of the screen 120 and the first adhesive block 110, respectively, to form the first semi-finished product.

[0069] S230, reference Figure 2 The upper part and reference Figure 3 In the left half of the second portion 220 , a clearance hole 221 is cut out, wherein the size of the clearance hole 221 is larger than the size of the protective film 150 .

[0070] S320, reference Figure 4 The upper part and Figure 5 The left half of the second portion 220 is laminated with a foam layer 600 and a second double-sided tape 500 in sequence above the second portion 220 .

[0071] S330, reference Figure 4 The upper part and Figure 5 The left half of the second portion 220 is die-cut for the first time, so that the second through hole 130a is formed on the second double-sided tape 500 and the third through hole 140a is formed on the foam layer 600.

[0072] S340, reference Figure 5 The left half of the composite base film 700 is formed below the second portion 220 .

[0073] S420, reference Figure 6 The upper part and Figure 7 The left half of the second part 220 is die-cut for the second time to form a third half-cut line 830 on the second double-sided tape 500 and the foam layer 600, and the third half-cut line 830 corresponds to the partial outline of the second rubber block 130 and the foam block 140.

[0074] S520, reference Figure 8 The upper part and Figure 9 The left half of the second part 220 is die-cut for the third time to form a fourth half-cut line 840 on the second double-sided tape 500, the foam layer 600, and the base film 700. The fourth half-cut line 840 corresponds to a partial outline of the second rubber block 130, the foam block 140, and the protective film 150; and the fourth half-cut line 840 and the third half-cut line 830 cooperate to form the second rubber block 130 and the foam block 140 on the second double-sided tape 500 and the foam layer 600, respectively.

[0075] S530, reference Figure 8 The upper part and Figure 9 The left half of the second part 220 is die-cut for the fourth time to form a fifth half-cut line 850 on the base film 700, and the fifth half-cut line 850 corresponds to a partial outline of the protective film 150; and the fifth half-cut line 850, and the fifth half-cut line 850 and the fourth half-cut line 840 cooperate to form a protective film 150 on the base film 700, wherein the protective film 150 is attached to the bottom of the foam block 140 through the air-avoiding hole 221.

[0076] It can be understood that the combination of the second rubber block 130 and the foam block 140 is defined as a second semi-finished product, and the second double-sided tape 500 and the foam layer 600 are used to form the second rubber block 130 and the foam block 140 respectively.

[0077] In step S330, the second portion 220 is die-cut for the first time, so that the second through hole 130a of the second adhesive block 130 and the third through hole 140a of the foam block 140 are formed in the second double-sided tape 500 and the foam layer 600, respectively. In step S420, the second portion 220 is die-cut for the second time, and in step S520, the second portion 220 is die-cut for the third time, so that the second double-sided tape 500 and the foam layer 600 are formed into the corresponding shapes of the second adhesive block 130 and the foam block 140, thereby forming a second semi-finished product.

[0078] In addition, through step S420, the second portion 220 is die-cut for the second time, and step S530, the second portion 220 is die-cut for the fourth time, so that the base film 700 is formed into a shape corresponding to the protective film 150, thereby forming the protective film 150. Specifically, the protective film 150 of the present application is provided with a fourth through hole 150a, which can be formed on the base film 700 in step S530.

[0079] Since a void hole 221 is formed on the bottom film 200 and the size of the void hole 221 is larger than the size of the protective film 150, after the shape of the protective film 150 is cut out, the protective film 150 can be compounded under the foam block 140 through the void hole 221, thereby obtaining a combination of the second semi-finished product and the protective film 150.

[0080] S600, reference Figure 10, cut the bottom film 200 to separate the first part 210 and the second part 220 , and composite the first part 210 on the second part 220 so that the side of the screen 120 away from the first adhesive block 110 is attached to the second adhesive block 130 .

[0081] It can be understood that after the first semi-finished product, the second semi-finished product and the protective film 150 are formed, the first part 210 and the second part 220 are separated through step S600, so that the first semi-finished product and the second semi-finished product are separated, and then the first semi-finished product is turned upside down on the second semi-finished product, and the screen 120 and the second glue block 130 are compounded, and then the above-mentioned die-cut product 100 is obtained.

[0082] The die-cutting process according to the first embodiment of the present application has at least the following beneficial effects:

[0083] First, through the above steps, the first semi-finished product and the second semi-finished product are formed separately, that is, the screen 120 and the foam block 140 are formed separately. During the die-cutting process of the foam layer 600, the foam layer 600 is not cut together with the screen layer 400, thereby ensuring the cutting quality of the foam layer 600. In addition, the outer shape of the screen 120 is also formed by forming half-cut lines in two die-cutting processes, thereby ensuring the cutting quality of the screen layer 400.

[0084] Secondly, by using the same base film 200 and dividing it into the first part 210 and the second part 220 , the first part 210 and the second part 220 can be processed simultaneously, thereby improving production efficiency.

[0085] Thirdly, by forming the air-avoidance holes 221 , the base film 700 can be laminated on the bottom film 200 from below after the second double-sided tape 500 and the foam layer 600 punch out the second through holes 130 a and the third through holes 140 a .

[0086] According to some embodiments of the present application, the following steps are further included:

[0087] Reference Figure 2 , forming a first positioning hole 211 and a second positioning hole 222 on the first portion 210 and the second portion 220 respectively;

[0088] Reference Figure 10 In the process of combining the first part 210 with the second part 220 , the first positioning hole 211 and the second positioning hole 222 are formed.

[0089] It can be understood that the first positioning hole 211 and the second positioning hole 222 are formed on the first part 210 and the second part 220. When the first part 210 is composited with the second part 220 in step 600, the first positioning hole 211 and the second positioning hole 222 are aligned to ensure the accurate fitting of the first semi-finished product and the second semi-finished product.

[0090] According to some embodiments of the present application, referring to Figure 2 and Figure 3 Step S220, performing the first die-cutting on the first portion 210, and step S230, cutting the avoidance hole 221 in the second portion 220 are completed at the first station, thereby improving production efficiency.

[0091] According to some embodiments of the present application, referring to Figure 4 and Figure 5 In step S330, the first die-cutting of the second part 220 is completed at the second station.

[0092] According to some embodiments of the present application, referring to Figure 6 and Figure 7 Steps S410, performing a second die-cutting on the first portion 210, and S420, performing a second die-cutting on the second portion 220 are completed at the third station, thereby improving production efficiency.

[0093] According to some embodiments of the present application, referring to Figure 8 and Figure 9 Step S510, performing the third die-cutting on the first part 210, step S520, performing the third die-cutting on the second part 220, and step S530, performing the fourth die-cutting on the second part 220 are completed at the fourth station, thereby improving production efficiency.

[0094] According to some embodiments of the present application, the die-cutting process of the present application further includes the following steps: Figure 2 , a circular hole 201 is cut in the middle of the bottom film 200 .

[0095] It can be understood that the circular hole 201 is used to eliminate the tension that damages the bottom supporting film 200 and prevent the composite material from being stretched and deformed.

[0096] According to some embodiments of the present application, referring to Figure 1 The first rubber block 110, the second rubber block 130, and the foam block 140 are all ring-shaped, and the outlines of the first rubber block 110, the second rubber block 130, the foam block 140 and the first through hole 110a, the second through hole 130a, and the third through hole 140a are all circular.

[0097] According to some embodiments of the present application, the following steps are also included: providing a base film 700, on which a glue layer is coated.

[0098] It is understandable that, since there is no supporting film material underneath the base film 700 , by coating the adhesive layer on the base film 700 , the formed protective film 150 can be more firmly compounded underneath the foam block 140 .

[0099] The die-cut product 100 according to the second embodiment of the present application is made by the die-cutting process of the first embodiment.

[0100] The die-cut product 100 according to the second embodiment of the present application has at least the following beneficial effects: including all the beneficial effects of the die-cutting process of the above-mentioned first embodiment, which will not be repeated here.
