[0040] With reference to Figures 1 to 3 , the wrapping jig according to the embodiments of the present application comprises a body 100, a limiting plate 200 and a folding plate 300.
[0041] With reference to Figures 1 to 3 , the body 100 forms a bending channel 110 and a guiding channel 120 along the conveying direction of the film material, the bending channel 110 extends along the conveying direction, the bending channel 110 has a bottom side 111 and two side sides 112 located on both sides of the width direction of the bottom side 111, the bottom side 111 is at least partially curved inwardly, the bending amplitude of the bottom side 111 increases along the conveying direction, and the distance between the two side sides 112 decreases along the conveying direction; the guiding channel 120 communicates with the output end of the bending channel 110, and the vertical section of the guiding channel 120 corresponds to the vertical section of the output end of the bending channel 110;
[0042] With reference to Figures 1 to 3 , the limiting plate 200 is arranged at the upper end of the body 100 and corresponds to the bending channel 110, the lower end of the limiting plate 200 is provided with a protrusion 210, the protrusion 210 is inserted into the bending channel 110, and the two sides of the width direction of the protrusion 210 are respectively arranged with a spacing between the two side sides 112;
[0043] With reference to Figure 5 , Figure 7 and Figure 8 , the folding plate 300 is arranged at the upper end of the body 100 and corresponds to the guiding channel 120, the folding plate 300 is formed with a first folding surface 310, a second folding surface 320 and a pressing surface 330 along the conveying direction, the first folding surface 310 and the second folding surface 320 are both arranged obliquely, the first folding surface 310 and the second folding surface 320 are respectively used for guiding the two ends of the film material in the width direction to bend inwardly, and the pressing surface 330 is used for pressing one end of the film material to the back side of the other end.
[0044] It is understood that the film material and the core rod 520 pass through the curved channel 110 and the guide channel 120 in sequence, and the core rod 520 is located in the middle of the film material. It is understood that the film material is parallel to the horizontal plane before entering the curved channel 110. Subsequently, the film material will be attached to the bottom side 111 of the curved channel 110. Since the lower side of the curved channel 110 is bent inward, the bending amplitude of the lower side increases along the conveying direction. Therefore, in the process of the film material passing through the curved channel 110, the two ends of the film material in the width direction will bend inward along with the bending of the bottom side 111, so that the film material bends in the direction of wrapping around the core rod 520. Moreover, as the distance between the two side surfaces 112 decreases along the conveying direction, the two ends of the film material in the width direction further bend inward and are guided by the side surfaces 112, and the film material further bends in the direction of wrapping around the core rod 520. Specifically, at the outlet end of curved channel 110, the two ends of the lower side surface have been bent to connect with the two side surfaces 112. The lower side surface and the two side surfaces 112 give the outlet end of curved channel 110 a U-shaped vertical cross-section. When the film passes through the outlet end of curved channel 110, the vertical cross-section of the film also forms a roughly U-shaped shape, and the film adheres to both sides of the core rod 520 in the width direction. The film enters the guide channel 120 through the outlet end of curved channel 110. Because the vertical cross-section of guide channel 120 corresponds to the vertical cross-section of the outlet end of curved channel 110, guide channel 120 can be used to keep the film in a curved state.
[0045] It can be understood that the limit plate 200 is arranged corresponding to the curved channel 110, and the protrusion 210 at the lower end of the limit plate 200 is inserted into the curved channel 110. The two sides of the protrusion 210 in the width direction are spaced apart from the two side surfaces 112. After the two ends of the membrane material are bent, they can enter between the side surfaces and side surfaces 112 of the protrusion 210. The side surfaces and side surfaces 112 of the protrusion 210 guide and limit the two ends of the membrane material. The protrusion 210 can block the two ends of the membrane material to prevent the two ends of the membrane material from bending too early or the bending posture is incorrect, so as to prevent the membrane material from being unable to wrap the core rod 520.
[0046] It is understandable that, referring to Figure 9The first folding surface 310 guides the transmission of one end of the film material to make the one end of the film material fold towards the other end, and the one end of the film material covers the upper side of the mandrel 520. Similarly, the second folding surface 320 guides the transmission of the other end of the film material to make the other end of the film material fold towards the one end of the film material, and the other end of the film material covers the back side of the one end of the film material, so that the film material wraps the mandrel 520. Specifically, the other end of the film material is attached with double-sided adhesive tape 540, and when the other end of the film material covers the back side of the one end of the film material, the two ends of the film material are bonded by the double-sided adhesive tape 540 to make the film material maintain the posture of wrapping the mandrel 520. Subsequently, the film material will pass through the pressing surface 330 to make the two ends of the film material further adhere to each other.
[0047] In summary, the film material and the mandrel 520 can pass through the bending channel 110 and the guide channel 120 in sequence. The bottom side surface 111 and the edge side surface 112 of the bending channel 110 guide the film material to make the two ends of the film material in the width direction gradually bend towards the direction of wrapping the mandrel 520, and make the film material adhere to the two sides of the mandrel 520 in the width direction. In addition, the protrusion 210 at the lower end of the limiting plate 200 improves the guiding effect on the film material to avoid the two ends of the film material from being bent too much. The film material passing through the bending channel 110 will enter the guide channel 120, and the first folding surface 310 and the second folding surface 320 on the folding plate 300 guide the two ends of the film material in the width direction in sequence to make the two ends of the film material fold, and the one end of the film material covers the upper side of the mandrel 520, and the other end of the film material covers the back side of the one end of the film material, so that the film material wraps the mandrel 520, and the two ends of the film material further adhere to each other through the pressing surface 330. The wrapping jig of the present application can ensure that the film material can wrap the film material while continuously transmitting the film material and the mandrel 520, thereby ensuring the continuity of production and improving the production efficiency.
[0048] With reference to Figure 4 and Figure 6 According to some embodiments of the present application, the two sides of the protrusion 210 in the width direction form guide surfaces 211, the guide surfaces 211 are arc surfaces, and the spacing between the two guide surfaces 211 decreases along the conveying direction.
[0049] It can be understood that the guide surfaces 211 on the two sides of the protrusion 210 are arc surfaces, and the spacing between the guide surfaces 211 decreases along the conveying direction, so that the guide surfaces 211 adapt to the changes of the bottom side surface 111 and the edge side surface 112, thereby better guiding the two ends of the film material. Specifically, the bending change rate of the guide surface 211 corresponds to the bending change rate of the bottom side surface 111, and the change amount of the spacing between the two guide surfaces 211 corresponds to the change rate of the spacing between the two edge side surfaces 112.
[0050] With reference to Figure 4 and Figure 6According to some embodiments of the present application, the middle part of the protrusion 210 is provided with a limiting slot 212 extending along the conveying direction, and the limiting slot 212 is used for passing the mandrel 520.
[0051] It can be understood that the mandrel 520 is limited by the limiting slot 212, so as to ensure the accuracy of the position of the mandrel 520, and avoid that the film material is prematurely attached to the mandrel 520, so as to cause inaccurate attachment position and thus unable to completely wrap the mandrel 520. It should be understood that the length of the limiting slot 212 is shorter than the length of the bending channel 110, so that after the film material is guided to a certain bending degree by the bending channel 110, the two ends of the film material can be attached to the two sides of the mandrel 520.
[0052] Referring to Figure 5 , Figure 7 and Figure 8 , according to some embodiments of the present application, the folding plate 300 is provided with a discharging channel 350 between the first folding surface 310 and the second folding surface 320, and the discharging channel is communicated with the guide channel 120 and used for discharging part of the film material.
[0053] It can be understood that in some application scenarios, in order to ensure the quality of the finished product, referring to Figure 9 , a protective film 530 is attached to the bottom side of the film material, and in order to avoid the influence of the protective film 530 on the adhesion of the two ends of the film material, the protective film 530 needs to be removed before the film material passes through the second folding surface 320. Therefore, the protective film 530 can leave the guide channel 120 through the discharging channel 350 and be wound by the winding roller, so as to ensure the normal removal of the protective film 530 without affecting the normal conveying and wrapping process of the film material.
[0054] Referring to Figure 7 and Figure 8 , according to some embodiments of the present application, the first folding surface 310 is an arc surface.
[0055] It can be understood that the first folding surface 310 is curved along the direction required for folding the film material, so as to improve the guiding effect of the one end of the film material and make the one end of the film material completely folded.
[0056] Referring to Figure 7 and Figure 8 , according to some embodiments of the present application, the second folding surface 320 is a straight surface.
[0057] It can be understood that the second folding surface 320 is a straight surface, and the second folding surface 320 is inclined downward along the conveying direction of the film material, and the back side of the other end of the film material abuts against the second folding surface 320. As the second folding surface 320 is more and more inclined downward, the second folding surface 320 bends the other end of the film material downward, so that the other end of the film material is folded on the back side of the one end of the film material.
[0058] Specifically, the second folding surface 320 is arranged as a straight surface, which can weaken the folding effect of the other end of the film material, so as to avoid the other end of the film material from being folded excessively and protruding from the one end of the film material. Further, the blocking surface 340 is arranged on the side of the folding plate 300 corresponding to the second folding surface 320, which is used to block the other end of the film material from protruding from the one end of the film material and avoid the film material from being wrapped excessively.
[0059] With reference to Figure 1 and Figure 2 According to some embodiments of the present application, a plurality of curved channels 110 and guide channels 120 are arranged on the body 100, the curved channels 110 and the guide channels 120 correspond to each other, and the plurality of curved channels 110 and the plurality of guide channels 120 are distributed along the width direction of the body 100.
[0060] It can be understood that each curved channel 110 and guide channel 120 corresponds to a group of film materials and core rods 520, and by arranging a plurality of curved channels 110 and guide channels 120, the plurality of groups of film materials and core rods 520 can be guided at the same time, so that the plurality of film materials can wrap the core rod 520 at the same time, thereby improving the production efficiency.
[0061] With reference to Figure 6 According to some embodiments of the present application, a plurality of protrusions 210 are arranged on the lower end of the limiting plate 200, and the protrusions 210 correspond to the curved channels 110 one by one.
[0062] It can be understood that a plurality of protrusions 210 are arranged on the lower end of one limiting plate 200, and the plurality of protrusions 210 guide the film materials in the corresponding curved channels 110 respectively. In addition, the plurality of protrusions 210 arranged on the lower end of one limiting plate 200 can facilitate the installation of the limiting plate 200.
[0063] With reference to Figure 1 and Figure 2 According to some embodiments of the present application, a plurality of folding plates 300 are arranged, the folding plates 300 correspond to the guide channels 120 one by one, and the two adjacent folding plates 300 in the width direction are distributed staggered in the conveying direction.
[0064] It can be understood that the plurality of folding plates 300 guide the two ends of the film materials in the plurality of guide channels 120 respectively. It should be noted that the folding plate 300 has a certain width size, and by arranging the two adjacent folding plates 300 in the width direction staggered in the conveying direction, the space utilization is improved, so that the spacing between the two adjacent guide channels 120 can be reduced, thereby reducing the width size of the body 100.
[0065] With reference to Figure 1According to some embodiments of the present application, the apparatus further comprises a conveying plate 400 located behind the body 100, a conveying channel 410 for the film material 510 is formed on the conveying plate 400, the inlet end of the conveying channel 410 for the film material 510 is opposite to the outlet end of the guide channel 120, and the conveying plate 400 is spaced apart from the body 100.
[0066] It can be understood that the film material can be output through the outlet end of the guide channel 120 to the inlet end of the conveying channel 410 for the film material 510 and be conveyed by the conveying channel 410 for the film material 510. It should be noted that the mandrel 520 and part of the film material are continuous, and the electromagnetic shielding products are independent single products. Therefore, a cutting mechanism can be arranged at a position corresponding to the interval between the conveying plate 400 and the body 100, the cutting mechanism cuts towards the interval between the conveying plate 400 and the body 100 to cut off the mandrel 520 and part of the film material, thereby forming a plurality of independent electromagnetic shielding products.
[0067] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
