[0025] Reference Figures 1 to 5 According to the first aspect of the present application, the electromagnetic shielding product production process comprises the following steps: Die-cutting the double-sided adhesive tape 100 to form the double-sided adhesive tape 100 into a set width; Die-cutting the hot melt adhesive 200 to form the hot melt adhesive 200 into a set width; Die-cutting the tape 300 to form the tape 300 into a set width; Die-cutting the conductive fabric 400 to form the conductive fabric 400 into a set width; The composite conductive cloth 400, the double-sided adhesive 100, the hot melt adhesive 200 and the adhesive tape 300 form a composite material strip 810, wherein the double-sided adhesive 100 is composited on the lower side of the conductive cloth 400, the hot melt adhesive 200 and the adhesive tape 300 are composited on the upper side of the conductive cloth 400, and the hot melt adhesive 200 and the adhesive tape 300 are located at both ends of the conductive cloth 400 in the width direction; Die-cutting the composite material strip 810 to cut the composite material strip 810 so that the conductive fabric 400, the double-sided adhesive tape 100, the hot melt adhesive tape 200 and the adhesive tape 300 form a set length to form a plurality of composite sections along the length direction; The mandrel 500 is compounded on the upper side of the compound section and adhered to the adhesive tape 300; The two ends of the composite section in the width direction are bent upward to form a wrapping member 820 of the composite section, wherein one end of the conductive cloth 400 attached with the hot melt adhesive 200 is wrapped around the back side of the other end of the conductive cloth 400, the hot melt adhesive 200 is attached to the back side of the other end of the conductive cloth 400, the conductive cloth 400 wraps the adhesive tape 300 and the core rod 500, and the bending of the conductive cloth 400 drives the adhesive tape 300 to bend and wrap the core rod 500; The package 820 is die-cut to allow the package 820 to be divided into a plurality of electromagnetic shielding products.

[0026] It can be understood that the double-sided adhesive 100, the hot melt adhesive 200, the tape 300 and the conductive cloth 400 are first die-cut separately so that the double-sided adhesive 100, the hot melt adhesive 200, the tape 300 and the conductive cloth 400 form set widths respectively. The set width can be the required width size of the double-sided adhesive 100, the hot melt adhesive 200, the tape 300 and the conductive cloth 400 in the electromagnetic shielding product. Then, the double-sided adhesive 100, the hot melt adhesive 200, the adhesive tape 300 and the conductive cloth 400 are compounded. It should be understood that the conductive cloth 400 is used to achieve the effect of electromagnetic shielding, and the hot melt adhesive 200 is used to adhere to both sides of the conductive cloth 400 in the width direction after the conductive cloth 400 is wound and wrapped, so as to keep the conductive cloth 400 in a wound state, and the adhesive tape 300 has a certain elasticity and can play a role in supporting the conductive cloth 400. Therefore, the hot melt adhesive 200 is attached to one end of the conductive cloth 400 in the width direction, so that the hot melt adhesive 200 can adhere to both ends of the conductive cloth 400 in the width direction after the conductive cloth 400 is wound, and then the adhesive tape 300 is set at the other end of the conductive cloth 400, and the adhesive tape 300 has a longer width, which can support the conductive cloth 400 with a large area after the conductive cloth 400 is wound. After the conductive cloth 400, the double-sided adhesive 100, the hot melt adhesive 200 and the tape 300 are attached to form the composite tape 810, the composite tape 810 continues to be output forward, and then the composite tape 810 is cut by a circular knife to form the conductive cloth 400, the double-sided adhesive 100, the hot melt adhesive 200 and the tape 300 to a set length. The set length can be the length required by the double-sided adhesive 100, the hot melt adhesive 200, the tape 300 and the conductive cloth 400 in the electromagnetic shielding product to form multiple composite sections along the length direction. It should be understood that in order to facilitate the continuous transmission of multiple composite sections, multiple composite sections can be supported by a carrier tape or other tapes. Subsequently, the mandrel 500 is compounded with the composite section, the mandrel 500 is compounded on the upper side of the tape 300, and the mandrel 500 is outputted into the wrapping jig 930 together. The two ends of the composite section in the width direction are bent by the wrapping jig 930, so that the two ends of the conductive cloth 400 in the composite section are wound inward, and the tape 300 and the mandrel 500 originally located above the conductive cloth 400 are wrapped, and the end of the conductive cloth 400 attached with the tape 300 is first wound around the upper side of the mandrel 500, and then the end of the double-sided tape 100 is wound around the conductive cloth 400 attached with the tape 300. The back side of one end of the tape 300 is adhered to the two ends of the conductive cloth 400 by double-sided tape 100, so that the conductive cloth 400 remains wound and wrapped around the core rod 500. The tape 300 is relatively long, and the tape 300 can also bend with the conductive cloth 400 and wrap the core rod 500 during the bending of the conductive cloth 400, so that the tape 300 is on the outside of the core rod 500, and the conductive cloth 400 is wrapped around the outside of the tape 300. The tape 300 cooperates with the core rod 500 to support the conductive cloth 400 and form a wrapping piece 820.It should be understood that the core rod 500 is a continuous long strip, and one core rod 500 is inserted into multiple wrapping pieces 820 distributed along the length direction. Therefore, the wrapping pieces 820 are die-cut to cut off the core rod 500, so that the wrapping pieces 820 are independent of each other, thereby forming an electromagnetic shielding product.

[0027] It can be understood that the conductive cloth 400, double-sided adhesive 100, hot melt adhesive 200 and adhesive tape 300 are die-cut and composited to form a composite material strip 810, and then the composite material strip 810 is directly die-cut to form multiple composite sections, and the composite sections are directly wrapped with the core rod 500 to form multiple wrapping pieces 820, and then the wrapping pieces 820 are die-cut to form an electromagnetic shielding product. The entire production process is continuous, and there is no need to transfer materials in the middle, so the production efficiency is high. In addition, by attaching double-sided adhesive 100 to one end of the conductive cloth 400, after the conductive cloth 400 is wound around the core rod 500, the two ends of the conductive cloth 400 in the width direction are adhered by the double-sided adhesive 100, so that the conductive cloth 400 can maintain the posture of wrapping the core rod 500. By attaching the tape 300 to the other end of the conductive cloth 400 and moving the conductive cloth 400 around the core rod 500, the tape 300 is driven to wrap the core rod 500. The tape 300 is located between the core rod 500 and the conductive cloth 400, and the tape 300 can play a role in supporting the conductive cloth 400.

[0028] Reference Figures 1 to 3 According to some embodiments of the present application, the following steps are also included: Asynchronous compound segments to space compound segments along their length.

[0029] It is understandable that in order to avoid mutual interference between the composite segments, after the composite material strip 810 is cut into a plurality of composite segments, the spacing between the composite segments is increased through an asynchronous process.

[0030] Reference Figures 1 to 3 According to some embodiments of the present application, die-cutting the package 820 includes the following steps: The die cut is performed between the two wrapping pieces 820 to cut off the core rod 500 between the two wrapping pieces 820 .

[0031] It is understandable that the core rod 500 is in the shape of a long strip, and a core rod 500 will be passed through multiple wrapping pieces 820. The core rod 500 is cut by die-cutting between two wrapping pieces 820, so that the wrapping pieces 820 are independent of each other. It is also understandable that, since the composite sections are spaced apart by an asynchronous process, it is easy to cut the core rod 500, avoiding the risk of cutting the wrapping piece 820 by mistake. In addition, since there is a certain distance between the composite sections, part of the core rod 500 can be exposed outside the wrapping piece 820. After the core rod 500 is cut, part of the core rod 500 in the electromagnetic shielding product formed will be exposed outside the conductive cloth 400, so that the core rod 500 can be pulled out when in use.

[0032] Reference Figure 4 and Figure 5 According to some embodiments of the present application, the following steps are also included: A protective film 600 is attached to the lower side of the composite section; Die-cutting the protective film 600 so that the protective film 600 is divided into a plurality of side edges along a width direction; After both ends of the conductive cloth 400 in the width direction are bent, a plurality of side edges are wrapped around the outside of the conductive cloth 400 .

[0033] It can be understood that after the composite section is formed, a protective film 600 is attached to the lower side of the composite section, and then the protective film 600 is die-cut into multiple side edges. In the process of the conductive cloth 400 bending and wrapping the core rod 500, the side edges can play a role in protecting the conductive cloth 400, and the side edges have a certain hardness and can support the conductive cloth 400.

[0034] Reference Figure 4 and Figure 5 According to some embodiments of the present application, the side edges include a first side edge 610, a second side edge 620, a third side edge 630, a fourth side edge 640, and a fifth side edge 650. The first side edge 610 is attached to the bottom side of the conductive cloth 400, the second side edge 620 and the third side edge 630 are attached to both sides of the conductive cloth 400 in the width direction, and the fourth side edge 640 and the fifth side edge 650 are attached to the upper side of the conductive cloth 400.

[0035] It can be understood that after the conductive cloth 400 is bent and wrapped around the core rod 500, a bottom side, two sides in the width direction and an upper side will be formed. The first side 610 is longer and is attached to the bottom side of the conductive cloth 400. The second side 620 and the third side 630 are attached to the two sides in the width direction of the conductive cloth 400. The fourth side 640 and the fifth side 650 will be attached to the upper side of the conductive cloth 400 respectively.

[0036] Specifically, the fourth side 640 and the fifth side 650 are respectively attached to the two ends of the conductive cloth 400 in the width direction, wherein the fourth side 640 corresponds to the end of the conductive cloth 400 with the double-sided tape 100, and the fifth side 650 corresponds to the end of the conductive cloth 400 with the tape 300. Because the end of the conductive cloth 400 with the double-sided tape 100 will be attached to the back side of the end of the conductive cloth 400 with the tape 300, in order to avoid the fifth side 650 interfering with the attachment of the double-sided tape 100, the fifth side 650 can be rolled up before the conductive cloth 400 is completely wrapped.

[0037] Reference Figures 1 to 3 According to some embodiments of the present application, the following steps are also included: Attaching foam to the outer side of the wrapping member 820; Die cut the foam to form the foam into the desired shape.

[0038] It is understandable that the foam is attached to the outer side of the wrapping member 820 and die-cut to form the foam into a corresponding shape, which may be the shape of the foam in the electromagnetic shielding product. By attaching the foam to the outer side of the wrapping member 820, the foam can play a supporting and protective role after the wrapping member 820 forms a battery shielding product.

[0051] The composite material strip 810 is die-cut for the second time to cut the composite material strip 810, so that the conductive cloth 400, the double-sided adhesive 100, the hot melt adhesive 200 and the adhesive tape 300 form a set length, form a plurality of composite sections along the length direction, and form through holes on the conductive cloth 400.
