[0011] By adopting the above technical solution, when the identification mark of the blister sheet deviates from the preset identification position, the controller outputs an alarm signal, and then the operator adjusts the position of the identification mark of the blister sheet, thereby preventing the identification mark of the blister sheet from being adsorbed at the preset position of the bullet-proof product, thereby improving the blister packaging quality of the bullet-proof product.

[0012] Preferably, before installing the first covering surface on the blister mold of the blister machine, the bullet-proof product blister packaging process further comprises: if the material of the bullet-proof product is metal, sandblasting and degreasing the first covering surface and the second covering surface.

Then the operator immerses the bullet-proof product in an alkaline degreasing agent to remove grease on the first covering surface and the grease on the second covering surface, so that the blister sheet can be better adsorbed on the first covering surface and the second covering surface.

[0014] Preferably, the heating of the first blister sheet to a first preset temperature range, and / or the heating of the second blister sheet to a third preset temperature range, comprises: heating the blister sheet using a far-infrared heating element of the blister machine, wherein the far-infrared heating element is spaced apart from the blister sheet, and the far-infrared heating element is located on a side of the blister sheet away from the bulletproof product.

[0015] By adopting the above technical solution, the blister sheet is heated by a far-infrared heating element, which can avoid the blister sheet from directly contacting the heating element, and can avoid the temperature of a local area of ​​the blister sheet being too high, causing the blister sheet to melt. In addition, the far-infrared heating element can evenly emit far-infrared rays to the blister sheet, thereby evenly heating the blister sheet.

[0016] Preferably, before the temperature of the first blister sheet is cooled to a second preset temperature range, and / or before the temperature of the second blister sheet is cooled to a fourth preset temperature range, the bullet-proof product blister packaging process further comprises: using a fan of the blister machine to blow gas toward the blister sheet.

[0017] By adopting the above technical solution, the fan is used to blow gas to the blister sheet, so that the cooling speed of the blister sheet can be increased, and then the blister packaging efficiency of the bullet-proof product can be improved.

[0020] Preferably, the blister sheet further comprises an adhesive layer, wherein the adhesive layer is suitable for adhering to the covering surface, and the adhesive layer is used to increase the adhesion between the blister sheet and the bullet-proof product.

[0021] By adopting the above technical solution, when the blister sheet is adsorbed on the bullet-proof product, the adhesive layer directly contacts the first covering surface and the second covering surface, thereby preventing the blister sheet from falling off the bullet-proof product as much as possible, thereby improving the blister packaging quality of the bullet-proof product.

[0027] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0028] The embodiment of the present application discloses a blister packaging process for bulletproof products.

[0029] Reference Figure 1 According to the blister packaging process for the bullet-proof product 1 described in the embodiment of the present application, along a first direction of the bullet-proof product 1 , the bullet-proof product 1 includes a first covering surface 11 and a second covering surface 12 that are opposite and spaced apart.

[0030] In some specific embodiments, the bulletproof product 1 may be a bulletproof shield, the first direction of the bulletproof product 1 may refer to the thickness direction of the bulletproof shield, the surface of the bulletproof shield used to protect external objects is the first covering surface 11, and the surface of the bulletproof shield used for the user to hold is the second covering surface 12.

[0031] In some other specific embodiments, referring to Figure 2 The bulletproof product 1 may be a bulletproof helmet. The first direction of the bulletproof product 1 may refer to the height direction of the bulletproof helmet. The lower surface of the bulletproof helmet is the first covering surface 11. The upper surface of the bulletproof helmet is the second covering surface 12. The height direction of the bulletproof helmet may refer to Figure 1 The up and down directions in .

[0032] Bulletproof product 1 blister packaging process includes: S1. Install the first covering surface 11 on the blister mold of the blister machine. Specifically, the operator installs the bulletproof product 1 on the blister mold of the blister machine, and the first covering surface 11 is tightly fitted with the blister mold, thereby preventing the bulletproof product 1 from tilting, which makes it difficult for the first blister sheet 21 to be fully adsorbed on the second covering surface 12, and avoiding wrinkles and dislocation of the first blister sheet 21 after the first blister sheet 21 is adsorbed on the second covering surface 12, thereby improving the blister packaging quality of the bulletproof product 1.

[0033] Furthermore, before installing the bulletproof product 1 on the blister mold, the operator needs to clean and remove dust or debris on the surface of the blister mold, so as to avoid the first covering surface 11 from failing to fit tightly with the blister mold and to avoid debris on the surface of the blister mold from damaging the bulletproof product 1.

[0034] S2. Install the first blister sheet 21 on the sheet clamp of the blister machine, and heat the first blister sheet 21 to a first preset temperature range, wherein the first blister sheet 21 is arranged opposite to the second covering surface 12. Specifically, after the first blister sheet 21 is installed on the sheet clamp, the first blister sheet 21 is located above the second covering surface 12, and the first blister sheet 21 is clamped by the sheet clamp, thereby preventing the first blister sheet 21 from deviating from the preset position, resulting in the first blister sheet 21 not being heated uniformly, and preventing the partial area of ​​the first blister sheet 21 that has not been heated to the first preset temperature range from being difficult to be blistered on the second covering surface 12, and preventing the temperature of a partial area of ​​the first blister sheet 21 from exceeding the first preset temperature range, resulting in the melting of the first blister sheet 21.

[0035] In some specific embodiments, the material of the first blister sheet 21 may be polyurethane, but the present application is not limited thereto, and the material of the first blister sheet 21 may also be polyethylene, etc. It should be noted that the first preset temperature interval needs to be set according to the material of the first blister sheet 21. In some specific embodiments, when the material of the first blister sheet 21 is polyurethane, the first preset temperature interval may be 130°C-160°C. In other specific embodiments, when the material of the first blister sheet 21 is polyethylene, the first preset temperature interval may be 85°C-100°C.

[0036] S3. Use the blister mold to press the second covering surface 12 onto the first blister sheet 21, and evacuate the blister mold to a first air pressure range so that the first blister sheet 21 is adsorbed onto the second covering surface 12. Specifically, when the first blister sheet 21 is heated to a first preset temperature range, the blister machine drives the blister mold to move close to the first blister sheet 21 so that the second covering surface 12 is pressed onto the first blister sheet 21, and then the blister machine evacuates the blister mold to a first air pressure range so that the first blister sheet 21 is adsorbed onto the second covering surface 12 according to the shape of the second covering surface 12.

[0037] It should be noted that the blister mold has a plurality of air holes, which penetrate the blister mold and are connected to the gap formed between the first blister sheet 21 and the second covering surface 12. The blister machine is provided with a vacuum pump, which is connected to the plurality of air holes of the blister mold. The blister machine uses the vacuum pump to evacuate the blister mold to a first air pressure range, and the first air pressure range needs to be set according to the material of the first blister sheet 21.

[0038] In some specific embodiments, when the material of the first blister sheet 21 is polyethylene, the first air pressure range may be 0.06MPa to 0.09MPa. In other specific embodiments, when the material of the first blister sheet 21 is polycarbonate, the first air pressure range may be 0.08MPa-0.1MPa.

[0039] S4, after the temperature of the first blister sheet 21 is cooled to the second preset temperature range, the bullet-proof product 1 is turned over and the second covering surface 12 is installed on the blister mold. Specifically, after the temperature of the first blister sheet 21 is cooled to the second preset temperature range, the operator takes out the bullet-proof product 1 from the blister mold and turns the bullet-proof product 1 over, and then the operator installs the second covering surface 12 on the blister mold.

[0040] Furthermore, by cooling the temperature of the first blister sheet 21 to the second preset temperature range, the hardness of the first blister sheet 21 can be increased, thereby preventing the first blister sheet 21 from being deformed when the operator takes out the bullet-proof product 1 from the blister mold, thereby improving the blister packaging quality of the bullet-proof product 1.

[0041] It should be noted that the second preset temperature range needs to be set according to the material of the first blister sheet 21. In some specific embodiments, when the material of the first blister sheet 21 is polycarbonate, the first preset temperature range can be 70°C-90°C. In other specific embodiments, when the material of the first blister sheet 21 is polyethylene, the first preset temperature range can be 50°C-70°C.

[0042] Furthermore, after turning over the bulletproof product 1 and installing the second covering surface 12 on the blister mold, the operator needs to carefully check the installation position of the second covering surface 12 to ensure that the second covering surface 12 and the blister mold are correctly aligned and tightly fitted.

[0043] S5. Install the second blister sheet 22 on the sheet clamp, and heat the second blister sheet 22 to a third preset temperature range, wherein the second blister sheet 22 is arranged opposite to the first covering surface 11. Specifically, after the second blister sheet 22 is installed on the sheet clamp, the second blister sheet 22 is located above the first covering surface 11, and the second blister sheet 22 is clamped by the sheet clamp, thereby preventing the second blister sheet 22 from deviating from the preset position, resulting in the second blister sheet 22 being unable to be heated uniformly, and preventing the partial area of ​​the second blister sheet 22 that has not been heated to the third preset temperature range from being difficult to be blistered on the first covering surface 11, and preventing the temperature of a partial area of ​​the second blister sheet 22 from exceeding the third preset temperature range, resulting in the melting of the second blister sheet 22.

[0044] In some specific embodiments, the material of the second blister sheet 22 can be the same as the material of the first blister sheet 21. In other specific embodiments, the material of the second blister sheet 22 can also be different from the material of the first blister sheet 21. Designers can set the material of the first blister sheet 21 and the material of the second blister sheet 22 according to the packaging requirements of the bullet-proof product 1.

[0045] It should be noted that the third preset temperature range needs to be set according to the material of the second blister sheet 22. In some specific embodiments, when the material of the second blister sheet 22 is polyurethane, the third preset temperature range can be 130°C-160°C. In other specific embodiments, when the material of the second blister sheet 22 is polyethylene, the third preset temperature range can be 85°C-100°C.

[0046] S6. Use the blister mold to press the first covering surface 11 onto the second blister sheet 22, and evacuate the blister mold to a second air pressure range so that the second blister sheet 22 is adsorbed onto the first covering surface 11. Specifically, when the second blister sheet 22 is heated to a third preset temperature range, the blister machine drives the blister mold to move close to the second blister sheet 22 so that the first covering surface 11 is pressed onto the second blister sheet 22, and then the blister machine evacuates the blister mold to a second air pressure range so that the second blister sheet 22 is adsorbed onto the first covering surface 11 according to the shape of the first covering surface 11.

[0047] It should be noted that the second air pressure range needs to be set according to the material of the second blister sheet 22. In some specific embodiments, when the material of the second blister sheet 22 is polyethylene, the second air pressure range can be 0.06MPa to 0.09MPa. In other specific embodiments, when the material of the second blister sheet 22 is polycarbonate, the second air pressure range can be 0.08MPa-0.1MPa.

[0048] S7, after the temperature of the second blister sheet 22 is cooled to the fourth preset temperature range, the bullet-proof product 1 is output. Specifically, after the temperature of the second blister sheet 22 is cooled to the fourth preset temperature range, the operator takes out the bullet-proof product 1 from the blister mold, thereby completing the blister packaging of the bullet-proof product 1.

[0049] It should be noted that the fourth preset temperature range needs to be set according to the material of the second blister sheet 22. In some specific embodiments, when the material of the second blister sheet 22 is polycarbonate, the fourth preset temperature range can be 70°C-90°C. In other specific embodiments, when the material of the second blister sheet 22 is polyethylene, the fourth preset temperature range can be 50°C-70°C.

[0050] Thus, by heating the first blister sheet 21, and then using a blister mold to press the second covering surface 12 onto the first blister sheet 21, and evacuating the blister mold to a first air pressure range so that the first blister sheet 21 is adsorbed onto the second covering surface 12, and then turning over the bulletproof product 1 and installing the second covering surface 12 onto the blister mold, and then heating the second blister sheet 22, and then using a blister mold to press the first covering surface 11 onto the second blister sheet 22, and evacuating the blister mold to a second air pressure range so that the second blister sheet 22 is adsorbed onto the first covering surface 11, compared with the prior art, the present application coats the outer peripheral wall of the bulletproof product 1 with a protective layer through a blister process, thereby preventing the health of the operator from being adversely affected by toxic substances when the outer peripheral wall of the bulletproof product 1 is coated with a protective layer.

[0051] In some embodiments of the present application, after the temperature of the second blister sheet 22 is cooled to the fourth preset temperature range and the bullet-proof product 1 is output, the blister packaging process of the bullet-proof product 1 may further include the following steps: S8. Wrap one of the edge of the first blister sheet 21 and the edge of the second blister sheet 22 on the outside of the other, that is, the edge of the first blister sheet 21 can be wrapped on the outside of the edge of the second blister sheet 22, or the edge of the second blister sheet 22 can be wrapped on the outside of the edge of the first blister sheet 21. It should be noted that the edge of the first blister sheet 21 refers to the edge area of ​​the first blister sheet 21 close to the first covering surface 11, and the edge of the second blister sheet 22 refers to the edge area of ​​the second blister sheet 22 close to the second covering surface 12.

[0052] By wrapping one of the edges of the first blister sheet 21 and the second blister sheet 22 around the outside of the other so that the edge of the first blister sheet 21 and the edge of the second blister sheet 22 overlap, it is possible to prevent the user's hands from being scratched by the edge of the first blister sheet 21 or the edge of the second blister sheet 22 when using the bullet-proof product 1, thereby improving the safety of the bullet-proof product 1.

[0053] In addition, the edge of the first blister sheet 21 and the edge of the second blister sheet 22 are both coated with glue. In some specific embodiments, the edge of the first blister sheet 21 is wrapped around the outside of the edge of the second blister sheet 22. By coating the edge of the first blister sheet 21 and the edge of the second blister sheet 22 with glue, the edge of the second blister sheet 22 is adhered to the outer surface of the bullet-proof product 1, and the edge of the first blister sheet 21 is adhered to the edge of the second blister sheet 22.

[0054] S9. Punching holes is performed on the first blister sheet 21 and the second blister sheet 22 to reveal the prefabricated holes of the bulletproof product 1. Specifically, the outer peripheral wall of the bulletproof product 1 is provided with prefabricated holes, and the accessories of the bulletproof product 1 can be installed on the bulletproof product 1 through the prefabricated holes. By punching holes on the first blister sheet 21 and the second blister sheet 22, the prefabricated holes of the bulletproof product 1 can be prevented from being covered by the first blister sheet 21 and the second blister sheet 22, so that the accessories of the bulletproof product 1 can be prevented from being unable to be installed on the bulletproof product 1.

[0055] In some specific embodiments, the user may punch holes in the first blister sheet 21 and the second blister sheet 22 by using a drill.

[0056] In some embodiments of the present application, after the temperature of the first blister sheet 21 is cooled to the second preset temperature range, and / or after the temperature of the second blister sheet 22 is cooled to the fourth preset temperature range, after the bullet-proof product 1 is output, the blister packaging process of the bullet-proof product 1 may further include the following steps: S41, cutting the blister sheet 2 to remove excess blister sheet 2, specifically, after the temperature of the first blister sheet 21 is cooled to the second preset temperature range, the operator cuts the area of ​​the first blister sheet 21 that is not adsorbed on the second covering surface 12, and after the temperature of the second blister sheet 22 is cooled to the fourth preset temperature range, after the bullet-proof product 1 is output, the operator cuts the area of ​​the second blister sheet 22 that is not adsorbed on the first covering surface 11, so that the difficulty of wrapping one of the edge of the first blister sheet 21 and the edge of the second blister sheet 22 on the outside of the other can be reduced, thereby improving the blister packaging efficiency of the bullet-proof product 1.

[0057] It should be noted that before wrapping one of the edges of the first blister sheet 21 and the second blister sheet 22 around the other, the operator cuts the area of ​​the second blister sheet 22 that is not adsorbed on the first covering surface 11 .

[0058] In some specific embodiments, after the temperature of the first blister sheet 21 is cooled to the second preset temperature range, and after the temperature of the second blister sheet 22 is cooled to the fourth preset temperature range, after the bullet-proof product 1 is output, the operator can cut the first blister sheet 21 and the second blister sheet 22.

[0059] In some specific embodiments, the operator can cut the first blister sheet 21 and the second blister sheet 22 by laser, but the present application is not limited to this. The operator can also cut the first blister sheet 21 and the second blister sheet 22 by a cutter. It should be noted that before the operator cuts the first blister sheet 21 and the second blister sheet 22, the operator places the bulletproof product 1 on a cutting fixture, and the cutting fixture is used to fix the bulletproof product 1.

[0060] In some embodiments of the present application, after the first blister sheet 21 is installed on the sheet fixture of the blister machine, and / or after the second blister sheet 22 is installed on the sheet fixture of the blister machine, the blister packaging process of the bullet-proof product 1 further includes the following steps: S10. Determine whether the identification mark of the blister sheet 2 is located at a preset identification position. Specifically, a CCD (Charge coupled device) camera and a controller are provided in the blister machine. The controller and the CCD camera are communicatively connected. The CCD camera is arranged opposite to the blister sheet 2. After the blister sheet 2 is installed on the sheet fixture, the CCD camera photographs the identification mark of the blister sheet 2. Then, the CCD camera transmits the identification mark image of the blister sheet 2 to the controller. The controller determines whether the identification mark of the blister sheet 2 is located at a preset identification position according to the identification mark image of the blister sheet 2.

[0061] It should be noted that the CCD camera only photographs the first blister sheet 21 when the first blister sheet 21 is provided with an identification mark, and the CCD camera only photographs the second blister sheet 22 when the second blister sheet 22 is provided with an identification mark.

[0062] In some specific embodiments, both the first blister sheet 21 and the second blister sheet 22 may be provided with identification marks. In other specific embodiments, the identification marks of the blister sheet 2 may be trademarks, but the present application is not limited thereto, and the identification marks of the blister sheet 2 may also be slogans, etc.

[0063] S11. If the identification mark deviates from the preset identification position, an alarm signal is output. Specifically, the blister machine is provided with a warning light, and the controller and the warning light are both communicatively connected. When the identification mark of the blister sheet 2 deviates from the preset identification position, the controller outputs an alarm signal. The controller controls the warning light to light up according to the alarm signal, and then the operator adjusts the position of the identification mark of the blister sheet 2, thereby preventing the identification mark of the blister sheet 2 from being adsorbed at the preset position of the bullet-proof product 1, thereby improving the blister packaging quality of the bullet-proof product 1.

[0064] S12. If the identification mark is located at the preset identification position, a prompt signal is output. Specifically, the blister machine is provided with a prompt light. When the identification mark of the blister sheet 2 is located at the preset identification position, the controller transmits a prompt signal, and then the operator controls the blister machine to heat the blister sheet 2.

[0065] In some embodiments of the present application, before the first covering surface 11 is mounted on the blister mold of the blister machine, the blister packaging process of the bullet-proof product 1 may further include the following steps: S13. If the material of the bullet-proof product 1 is metal, the first covering surface 11 and the second covering surface 12 are both sandblasted and degreased. Specifically, the operator can use glass beads to sandblast the first covering surface 11 and the second covering surface 12 to remove surface impurities on the first covering surface 11 and the surface impurities on the second covering surface 12, and process the surface roughness of the first covering surface 11 and the surface roughness of the second covering surface 12 so that the blister sheet 2 can be better adsorbed on the first covering surface 11 and the second covering surface 12.

[0066] Then, the operator immerses the bulletproof product 1 in an alkaline degreasing agent to remove the grease on the first covering surface 11 and the grease on the second covering surface 12 , so that the blister sheet 2 can be better adsorbed on the first covering surface 11 and the second covering surface 12 .

[0070] In some embodiments of the present application, before the temperature of the first blister sheet 21 is cooled to the second preset temperature range, and / or before the temperature of the second blister sheet 22 is cooled to the fourth preset temperature range, the blister packaging process of the bullet-proof product 1 may further include the following steps: S42, using the fan of the blister machine to blow gas to the blister sheet 2. Specifically, the fan can be arranged above the blister sheet 2. By using the fan to blow gas to the blister sheet 2, the cooling speed of the blister sheet 2 can be increased, thereby improving the blister packaging efficiency of the bullet-proof product 1.

[0071] Reference Figure 3 In some embodiments of the present application, the blister sheet 2 includes a protective layer 221 and / or an electromagnetic shielding layer 222 and / or a signal absorbing layer 223 and / or an anti-infrared reflecting layer 224 and / or a wave-transmitting layer 225, wherein the protective layer 221 is used to protect the bulletproof product 1, the electromagnetic shielding layer 222 is used to prevent electromagnetic waves from penetrating the blister sheet 2, the signal absorbing layer 223 is used for signals of a preset band, and the wave-transmitting layer 225 is used to allow signals of a specific band to penetrate the blister sheet 2. It should be noted that the blister sheet 2 includes a first blister sheet 21 and a second blister sheet 22, and both the first blister sheet 21 and the second blister sheet 22 can include a protective layer 221 that can protect the electromagnetic shielding layer 222, the signal absorbing layer 223, the anti-infrared reflecting layer 224 and the wave-transmitting layer 225.

[0072] Specifically, after the blister sheet 2 is adsorbed on the bulletproof product 1, the protective layer 221 is located on the side of the electromagnetic shielding layer 222, the signal absorption layer 223, the anti-infrared reflection layer 224 and the wave-transmitting layer 225 away from the bulletproof product 1, so that the protective layer 221 can protect the electromagnetic shielding layer 222, the signal absorption layer 223, the anti-infrared reflection layer 224, the wave-transmitting layer 225 and the bulletproof product 1.

[0073] In some preferred embodiments, the blister sheet 2 may include a protective layer 221, an electromagnetic shielding layer 222, a signal absorbing layer 223, an anti-infrared reflecting layer 224 and a wave-transmitting layer 225. By adding the electromagnetic shielding layer 222, the signal absorbing layer 223, the anti-infrared reflecting layer 224 and the wave-transmitting layer 225 to the blister sheet 2, the bullet-proof product 1 can achieve the technical effect of electromagnetic shielding, and can reduce the probability of the bullet-proof product 1 being detected by radar, and can reduce the probability of the bullet-proof product 1 being detected by infrared thermal imaging, and can achieve the technical effect of the bullet-proof product 1 receiving characteristic band signals, thereby improving the use experience of the bullet-proof product 1.

[0074] In some specific embodiments, the material of the protective layer 221 may be polyethylene, but the present application is not limited thereto. The material of the protective layer 221 may also be polycarbonate or the like.

[0075] In other specific embodiments, the electromagnetic shielding layer 222 may be aluminum foil, the signal absorption layer 223 may be barium titanate, the anti-infrared reflection layer 224 may be zinc oxide coating and the wave-transmitting layer 225 may be quartz glass, but the present application is not limited thereto. The electromagnetic shielding layer 222 may also be polyaniline, the signal absorption layer 223 may also be iron oxide magnetic powder, the anti-infrared reflection layer 224 may also be silicon carbide, and the wave-transmitting layer 225 may also be magnesium fluoride, etc.

[0076] Reference Figure 3 In some embodiments of the present application, the blister sheet 2 further includes an adhesive layer 226, which is suitable for adhering to the covering surface. The adhesive layer 226 is used to increase the viscosity between the blister sheet 2 and the bullet-proof product 1. Specifically, when the blister sheet 2 is adsorbed on the bullet-proof product 1, the adhesive layer 226 directly contacts the first covering surface 11 and the second covering surface 12, thereby preventing the blister sheet 2 from falling off the bullet-proof product 1 as much as possible, thereby improving the blister packaging quality of the bullet-proof product 1.

[0077] It should be noted that the electromagnetic shielding layer 222 , the signal absorbing layer 223 , the anti-infrared reflection layer 224 and the wave-transmitting layer 225 are all located between the protective layer 221 and the adhesive layer 226 .

[0078] In some specific embodiments, the adhesive layer 226 may be a pressure-sensitive adhesive, but the present application is not limited thereto. The adhesive layer 226 may also be an acrylic adhesive or the like.

[0079] In some embodiments of the present application, the blister mold includes a first blister mold and a second blister mold. The shape of the first blister mold matches the shape of the first covering surface 11 , and the shape of the second blister mold matches the shape of the second covering surface 12 .

[0080] Specifically, when the bulletproof product 1 is a bulletproof helmet, the shape of the first covering surface 11 is different from the shape of the second covering surface 12. By matching the shape of the first blister mold with the shape of the first covering surface 11, and matching the shape of the second blister mold with the shape of the second covering surface 12, the first covering surface 11 can be tightly fitted with the first blister mold, and the second covering surface 12 can be tightly fitted with the second blister mold, so that both the first blister mold and the second blister mold can better support the bulletproof product 1, thereby avoiding as much as possible the occurrence of a gap between the first covering surface 11 and the first blister mold, and avoiding as much as possible the occurrence of a gap between the second covering surface 12 and the second blister mold, and avoiding when the covering surface is pressed onto the blister sheet 2, the blister sheet 2 squeezes the covering surface, causing wrinkles in the blister sheet 2, thereby improving the blister packaging quality of the bulletproof product 1.

[0081] In some specific embodiments, when the shape of the first covering surface 11 is the same as the shape of the second covering surface 12 , the shape of the first blister mold is the same as the shape of the second blister mold.

[0082] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
