DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0036] like Figures 1 to 2 As shown, a battery film carrying device is used to carry a battery 2 covered with a heat shrink film 3, and the battery film carrying device has a first direction Z, a second direction X and a third direction Y that intersect with each other;

[0037] include:

[0038] The loading platform 11 and the pressing plate 12 are movably connected along the first direction Z, and the distance between the loading platform 11 and the pressing plate 12 in the first direction Z is adjustable.

[0039] The battery 2 covered with the heat shrink film 3 is assembled between the stage 11 and the pressing plate 12 . The heat shrink film 3 includes a first area 31 . The first surface of the pressing plate 12 is in contact with the first area 31 .

[0040] Among them, the first area 31 is the area where the mark of the heat shrink film 3 is set, the first surface is the surface of the pressed plate 12 facing the worktable 11, the first surface is a curved surface, and the curvature of the first surface is equal to the curvature of the surface of the battery 2 facing the pressed plate 12. The first direction Z intersects with the plane where the pressed plate 12 is located, and the plane formed by the second direction X and the third direction Y is parallel to the plane where the pressed plate 12 is located.

[0041] As can be seen from the above embodiments, in the embodiments of the present utility model, since the battery film carrying device includes a loading platform 11 and a pressing plate 12 movably connected along the first direction Z, the distance between the loading platform 11 and the pressing plate 12 in the first direction Z is adjustable, so that a space for defining the battery 2 can be formed between the loading platform 11 and the pressing plate 12. Since the battery 2 with the heat shrink film 3 is assembled between the stage 11 and the pressing plate 12, the heat shrink film 3 includes a first area 31, and the first area 31 is in contact with the first surface of the pressing plate 12, wherein the first area 31 is the area where the mark of the heat shrink film 3 is set, and the first surface is the surface of the pressing plate 12 facing the stage 11. The first surface is an arc surface, and the curvature of the first surface is equal to the curvature of the surface of the battery 2 facing the pressing plate 12. Therefore, the first surface of the pressing plate and the first area 31 can be completely fitted together, so that the pressing plate 12 provides pressing protection for the area where the mark of the heat shrink film 3 is set, thereby avoiding irregular shrinkage caused by heat flow through the first area 31 when the rest of the heat shrink film 3 except the first area 31 is not tightened, thereby protecting the integrity of the mark in the first area 31, and thus providing a stable and reliable silk screen environment for the heat shrink film 3, thereby improving the yield rate of the battery 2.

[0042] The heat shrink film 3 in the above-mentioned embodiment is made of any material such as polyethylene or polypropylene, which provides excellent durability and heat resistance, effectively preventing the surface of the battery 2 from being scratched and worn. The heat shrink film 3 also enhances the waterproof performance of the battery 2, preventing damage from moisture in humid environments. Furthermore, the logo within the first region 31 of the heat shrink film 3 can be any logo, such as a trademark or battery information. After the heat shrink film 3 is wrapped around the battery 2, the first region 31 faces the laminated plate 12.

[0043] The pressed plate 12 is a plate-like structure having at least one pressed surface facing the battery 2, which is the first surface. Since the surface of the battery 2 is usually a curved surface, the first surface is also a curved surface, and the curvature of the first surface is equal to the curvature of the surface of the battery 2 facing the pressed plate 12, thereby facilitating the lamination between the pressed plate 12 and the first area 31.

[0044] The loading platform 11 is a supporting member that provides support for the battery 2. The loading platform 11 and the pressing plate 12 can be movably connected by at least one of a sliding connection, a snap connection, or an elastic connection, thereby making the distance between the loading platform 11 and the pressing plate 12 in the first direction Z adjustable. In this way, if the size of the battery 2 changes, that is, if the size of the battery 2 changes in the first direction Z, the distance between the loading platform 11 and the pressing plate 12 in the first direction Z can be adjusted, thereby changing the gap between the loading platform 11 and the pressing plate 12 in the first direction Z to accommodate the pressing requirements of batteries 2 of different sizes, thereby improving the adaptability of the battery film supporting device.

[0045] It should be noted that according to Figure 2 In the embodiment of the present invention, the X-axis direction and the Z-axis direction intersect, the X-axis direction and the Y-axis direction intersect, and the Y-axis direction and the Z-axis direction intersect. For the sake of convenience, the first direction is defined as the Z-axis direction (that is, the direction intersecting with the plane where the pressed plate 12 is located), the second direction is defined as the X-axis direction, and the third direction is defined as the Y-axis direction. It is further explained that the definition of vertical in the specification should be understood as vertical within a 90-degree fluctuation of 10%, that is, the angle between the first and second directions defined as between 80 and 90 degrees should be understood as vertical, the angle between the first and third directions defined as between 80 and 90 degrees should be understood as vertical, and the angle between the second and third directions defined as between 80 and 90 degrees should be understood as vertical.

[0046] It should also be noted that in the embodiment of the present invention, the first surface included in the pressed plate 12 can be a curved surface structure formed by a plate-like structure, and the first surface included in the pressed plate 12 can also be a curved surface structure formed after being pressed and deformed by external force. The embodiment of the present invention does not limit this.

[0047] In one possible implementation, the pressed plate 12 includes a protective cover 121 and a flexible plate 122 stacked along a first direction Z; the flexible plate 122 is arranged between the protective cover 121 and the battery, and when the protective cover 121 moves toward the direction close to the battery 2, the surface of the flexible plate 122 in contact with the first area 31 is deformed into the first surface.

[0048] In this embodiment, the laminated plate 12 includes a protective cover 121 and a flexible plate 122 stacked along a first direction Z; the flexible plate 122 is disposed between the protective cover 121 and the battery. When the protective cover 121 moves toward the battery 2, the surface of the flexible plate 122 in contact with the first region 31 is deformed into the first surface. Therefore, when the protective cover 121 moves toward the battery 2, the flexible plate 122 can be squeezed and deformed, and then the first surface is formed, so that the flexible plate 122 and the first region 31 are completely in contact. At the same time, because the flexible plate 122 has a certain elastic buffer, it can prevent the protective cover 121 from directly contacting the first region 31 and causing damage to the heat shrink film 3. The flexible plate 122 and the protective cover 121 can be connected by means of snapping, riveting, etc. It should be noted that the flexible plate 122 can be made of high-temperature resistant soft materials such as silicone, fluororubber, butyl rubber, etc., so that when elastic deformation is achieved, the flexible plate 122 can withstand high temperatures and avoid structural damage when entering the furnace.

[0049] In some embodiments, the protective cover 121 includes a pressure plate 1211 and at least one side panel 1212; the plane where the pressure plate 1211 is located is parallel to the plane formed by the second direction X and the third direction Y, the side panel 1212 is fixed at the edge position of the pressure plate 1211, and the plane where the side panel 1212 is located intersects with the plane where the pressure plate 1211 is located.

[0050] In this embodiment, there can be one or more side panels 1212, which is not limited in this embodiment of the present invention. Since the plane where the pressure plate 1211 is located is parallel to the plane formed by the second direction X and the third direction Y, the side panels 1212 are fixed to the edge of the pressure plate 1211, and the plane where the side panels 1212 are located intersects with the plane where the pressure plate 1211 is located, the pressure plate 1211 and the side panels 1212 can form an enclosed space, so that the flexible plate 122 can be installed in the enclosed space formed by the pressure plate 1211 and the side panels 1212, thereby allowing the test board to limit and protect the flexible plate 122.

[0051] In another possible implementation, the pressed plate 12 includes a protective cover 121; the surface of the protective cover 121 facing the battery is a first surface. In this embodiment, since the surface of the protective cover facing the battery is the first surface, the first surface of the protective cover 121 can be directly and completely bonded to the first area 31, so that the protective cover 121 provides pressed protection for the area where the heat shrink film 3 is provided with the marking, thereby simplifying the structure of the battery film carrier device and reducing the manufacturing cost of the battery film carrier device. In addition, the orthographic projection of the first surface along the first direction Z onto the plane formed by the second direction X and the third direction Y completely overlaps with the orthographic projection of the surface of the battery 2 facing the protective cover 121 along the first direction Z onto the plane formed by the second direction X and the third direction Y, thereby ensuring that the first surface and the surface of the battery 2 facing the protective cover 121 are completely bonded.

[0052] In some embodiments, the loading platform 11 includes a loading plate 111 and a sliding rod 112 ; the sliding rod 112 is fixed on the loading plate 111 , the sliding rod 112 extends along the first direction Z, and the pressing plate 12 is slidably connected to the sliding rod 112 .

[0053] In this way, the sliding rod 112 can guide the sliding between the carrier plate 111 and the pressing plate 12, thereby allowing the sliding between the carrier plate 111 and the pressing plate 12 to slide along the first direction Z, thereby preventing the pressing plate 12 from deflecting when approaching the carrier plate 111. In other words, during the process of adjusting the distance between the carrier plate 11 and the pressing plate 12 in the first direction Z, the plane where the carrier plate 111 is located and the plane where the pressing plate 12 is located are always parallel, thereby preventing the pressing plate 12 from being unable to fully fit into the first area 31, thereby ensuring the pressing effect of the pressing plate 12. It should be noted that the sliding between the pressing plate 12 and the sliding rod 112 can be achieved by providing a slide rail or a slide groove, etc., and the embodiments of the present invention are not limited to this.

[0054] In a possible embodiment, the pressing plate 12 is provided with a sliding slot 123 , and the sliding rod 112 is passed through the sliding slot 123 .

[0055] In this embodiment, the cross-sectional shape of the sliding slot 123 on the plane formed by the second direction X and the third direction Y and the cross-sectional shape of the sliding rod 112 on the plane formed by the second direction X and the third direction Y should be consistent. In this way, after the sliding rod 112 is inserted into the sliding slot 123, not only can the distance between the worktable 11 and the pressed plate 12 in the first direction (Z) be adjusted through the sliding slot 123, but the sliding slot 123 can also limit the sliding rod 112, so that when the sliding rod 112 slides in the sliding slot 123, the pressed plate 12 will not deviate laterally.

[0056] In another possible embodiment, participating Figure 4 A sliding protrusion 1121 is provided on the side wall of the sliding rod 112; a sliding groove 1213 extending along the first direction Z is provided on the side wall of the pressing plate 12, and the sliding protrusion 1121 is slidably connected in the sliding groove 1213. In this embodiment, the sliding protrusion 1121 slides in the sliding groove 1213, thereby causing the pressing plate 12 to slide on the sliding rod 112, thereby changing the distance between the worktable 11 and the pressing plate 12 in the first direction (Z). In this way, since in this embodiment, the sliding protrusion 1121 is provided on the side wall of the sliding rod 112 and the sliding groove 1213 is provided on the side wall of the pressing plate 12, it is possible to prevent the sliding rod 112 from passing through the pressing plate 12, thereby simplifying the structure while ensuring the pressing area of ​​the pressing plate 12.

[0057] It should be noted that in some possible implementation methods, the sliding rod 112 can be a telescopic rod of a cylinder, and the end of the sliding rod 112 is connected to the pressed plate 12. Then, the distance between the worktable 11 and the pressed plate 12 in a direction (Z) can be changed by the extension and retraction of the telescopic rod of the cylinder, thereby realizing automatic adjustment of the distance between the worktable 11 and the pressed plate 12 in a direction (Z).

[0058] In some embodiments, the battery film carrying device further includes a limiting base 13 ; a limiting groove 131 is defined on the limiting base 13 , and the loading platform 11 is embedded in the limiting groove 131 .

[0059] In this embodiment, the loading platform 11 is embedded in the limiting base 13 through the limiting groove 131, so that the battery film carrying device has a larger supporting area, ensuring that the battery film carrying device remains stable during transportation.

[0060] In some embodiments, the battery film carrying device further includes a clip; the clip is inserted between the side wall of the loading platform 11 and the wall of the limiting groove 131 .

[0061] In this embodiment, by inserting the card strip between the side wall of the loading platform 11 and the groove wall of the limiting groove 131, the loading platform 11 can be completely fixed on the limiting base 13, further improving the stability of the transportation of the battery film carrying device. At the same time, when removing the loading platform 11 from the limiting base 13, it is only necessary to remove the card strip, thereby facilitating the separation between the loading platform 11 and the limiting base 13.

[0062] As can be seen from the above embodiments, in the embodiments of the present utility model, since the battery film carrying device includes a loading platform 11 and a pressing plate 12 movably connected along the first direction Z, the distance between the loading platform 11 and the pressing plate 12 in the first direction Z is adjustable, so that a space for defining the battery 2 can be formed between the loading platform 11 and the pressing plate 12. Since the battery 2 with the heat shrink film 3 is assembled between the stage 11 and the pressing plate 12, the heat shrink film 3 includes a first area 31, and the first area 31 is in contact with the first surface of the pressing plate 12, wherein the first area 31 is the area where the mark of the heat shrink film 3 is set, and the first surface is the surface of the pressing plate 12 facing the stage 11. The first surface is an arc surface, and the curvature of the first surface is equal to the curvature of the surface of the battery 2 facing the pressing plate 12. Therefore, the first surface of the pressing plate and the first area 31 can be completely fitted together, so that the pressing plate 12 provides pressing protection for the area where the mark of the heat shrink film 3 is set, thereby avoiding irregular shrinkage caused by heat flow through the first area 31 when the rest of the heat shrink film 3 except the first area 31 is not tightened, thereby protecting the integrity of the mark in the first area 31, and thus providing a stable and reliable silk screen environment for the heat shrink film 3, thereby improving the yield rate of the battery 2.

[0063] In some embodiments, as Figure 3 As shown, the embodiment of the present invention further provides a heating device, which includes a conveyor 4 and a battery film carrying device 1 of any of the above embodiments, and a loading platform 11 is detachably connected to the conveyor 4. The heating device mentioned in this embodiment can be a heating furnace.

[0064] It should be noted that the conveying member 4 may be a conveyor belt, a conveying roller, or the like, and the loading platform 11 may be detachably connected to the conveying member 4 by means of a buckle, a magnetic member, a limit ring, or other structural platform, thereby ensuring that the battery film carrier 1 does not shift during the movement of the conveying member 4. At the same time, because the heating device includes the conveying member 4 and the battery film carrier 1 of any of the above-described embodiments, the first surface of the pressing plate and the first region 31 can be completely aligned, so that the pressing plate 12 provides pressing protection for the region where the mark of the heat shrinkable film 3 is set, thereby preventing the heat flow through the first region 31 and causing irregular shrinkage when the rest of the heat shrinkable film 3 other than the first region 31 is not tightened, thereby protecting the integrity of the mark in the first region 31, and thus facilitating the provision of a stable and reliable silk-screen printing environment for the heat shrinkable film 3, thereby improving the yield rate of the battery 2 and also improving the reliability and stability of the heating device.
