Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of pole coil packaging, and in particular to a pole coil packaging assembly and a packaging box. Background Art

[0002] The pole piece includes a pole ear at the end. The thickness of the pole ear is generally micrometer-level, so the pole ear is very fragile. The pole roll refers to the winding core formed after the pole piece is wound. After the pole roll is formed, the pole ear is located at the end of the pole roll.

[0003] Before the pole coil is transported, it is necessary to use a packaging box to pack the pole coil to ensure the quality of the pole coil. However, based on the structure of the existing packaging box, the pole coil packaging assembly easily causes damage to the pole ear at the end of the pole coil, making the pole coil unusable. Utility Model Content

[0004] The embodiments of the present application provide a pole coil packaging assembly and a packaging box to solve the problem that the existing pole coil packaging assembly is prone to cause pole ear damage, thereby achieving protection for the pole ear.

[0005] In a first aspect, an embodiment of the present application provides a pole roll packaging assembly. The pole roll packaging assembly includes a drum, a protective plate, and a limiter. The drum is used to wind the pole roll. The protective plate is sleeved on the peripheral wall of the drum and is located on the end side of the pole roll to protect the pole roll. The limiter includes a connecting portion and a limiting portion that are connected to each other. The connecting portion is connected to the protective plate. The limiting portion is used to abut against the end face of the drum to limit the protective plate so that a preset gap exists between the protective plate and the end face of the pole roll.

[0006] Considering the technical problem that the protection plate in the prior art easily damages the pole ear at the end of the pole roll. The embodiment of the present application provides a limiting member including a connecting portion and a limiting portion, and the limiting portion is provided to abut against the end face of the reel after the protection plate is sleeved on the predetermined position of the reel, so that the limiting portion can be limited by the end face of the reel and does not move in the direction close to the pole roll, and then the limiting portion can prevent the connection portion from moving in the direction close to the pole roll, and the connection portion can prevent the protection plate from moving in the direction close to the pole roll. In other words, the abutment between the limiting portion and the end face of the reel can maintain the protection plate at a predetermined position with a preset gap from the end face of the pole roll. In this way, the protection plate will not contact the pole roll to damage the pole ear.

[0007] In a possible design, the limiting part is configured as a limiting block, the surface of which abuts against the end face of the reel. Alternatively, the limiting part is configured as a limiting ring, the annular surface of which abuts against the end face of the reel. Alternatively, the limiting part is configured as a limiting plate, the plate surface of which abuts against the end face of the reel.

[0008] Through the above scheme, the end face of the drum can apply a force back to the pole roll to the surface of the limit block, the ring surface of the limit ring or the plate surface of the limit plate, so that the limit block, the limit ring or the limit plate does not move in the direction close to the pole roll.

[0009] In a possible design, when the limiting portion is configured as a limiting block, the end surface of the reel is provided with a limiting groove adapted to the limiting block. The limiting block can be embedded in the limiting groove, and the surface of the limiting block can abut against the groove wall of the limiting groove.

[0010] Through the above solution, the groove wall of the limiting groove can apply force to the surface of the limiting block to prevent the limiting block from moving in the direction close to the pole roll. In addition, the groove wall of the limiting groove can also apply force to the surface of the limiting block to prevent the limiting block from sliding on the end surface of the reel. When the limiting block does not slide on the end surface of the reel, the connecting part will not rotate with the sliding of the limiting block, and the protective plate will not rotate on the peripheral wall of the reel with the rotation of the connecting part, which is conducive to improving the stability of the protective plate sleeved on the reel.

[0011] In a possible design, when the limiting portion is configured as a limiting ring or a limiting plate, a limiting protrusion is provided on one side of the end surface of the limiting portion facing the reel. A limiting hole matching the limiting protrusion is provided on the end surface of the reel. The limiting protrusion can be embedded in the limiting hole, and the surface of the limiting protrusion can abut against the hole wall of the limiting hole.

[0012] Through the above scheme, on the basis of the abutment between the limiting ring or the limiting plate and the end face of the reel, the hole wall of the limiting hole can abut against the surface of the limiting protrusion and apply force to the limiting protrusion to prevent the limiting part from moving in the direction close to the pole roll. In addition, the hole wall of the limiting hole can also abut against the surface of the limiting protrusion and apply force to the limiting protrusion to prevent the limiting ring or the limiting plate from sliding on the end face of the reel. When the limiting ring or the limiting plate does not slide on the end face of the reel, the connecting part will not rotate with the sliding of the limiting ring or the limiting plate, and the protective plate will not rotate on the peripheral wall of the reel with the rotation of the connecting part, which is conducive to improving the stability of the protective plate sleeved on the reel.

[0013] In a possible design, the connecting portion is configured as a connecting rod, which is connected to the protection plate. Alternatively, the connecting portion is configured as a connecting plate, which is connected to the protection plate. Alternatively, the connecting portion is configured as a connecting cylinder, which is connected to the protection plate.

[0014] Through the above solution, when the limiting part is abutted by the end surface of the winding drum, the limiting part can apply a force to the connecting rod, the connecting plate or the connecting cylinder to face away from the pole winding. The connecting rod, the connecting plate or the connecting cylinder can apply a force to the protective plate to face away from the pole winding to prevent the protective plate from moving toward the pole winding, thereby preventing the protective plate from abutting against the pole winding and damaging the pole ear.

[0015] In a possible design, the connecting portion includes a first end face and a second end face. The first end face is connected to the protection plate, and the second end face is connected to the limiting portion. Alternatively, the middle portion of the connecting portion is connected to the protection plate, and the first end face or the second end face is connected to the limiting portion.

[0016] Through the above solution, the limiting portion can apply force to the end surface of the connecting portion, and the end surface or the middle portion of the connecting portion can apply force to the protective plate to limit the protective plate.

[0017] In a possible design, in the axial direction of the winding drum, within the same projection plane, the projection area of ​​the protection plate completely covers the projection area of ​​the pole winding.

[0018] Through the above solution, in the axial direction of the winding drum, the protection plate can completely cover the end surface of the pole winding to prevent the pole ear from being damaged by external force.

[0019] In a possible design, the pole roll packaging assembly further includes a packaging bag. The packaging bag is sleeved outside the roll, the protection plate and the pole roll. A support boss is provided on the side of the protection plate facing away from the pole roll, and the support boss is used to support the packaging bag.

[0020] Through the above solution, during the vacuum operation on the packaging bag, the supporting boss can support the packaging bag to prevent the packaging bag from deforming toward the tab and damaging the tab.

[0021] In a possible design, the plate surface of the protection plate is provided with reinforcing ribs.

[0022] Through the above solution, the reinforcing ribs can increase the strength of the protection plate.

[0023] In a second aspect, the present application also provides a packaging box. The packaging box includes a box body and the pole coil packaging assembly of the first aspect. The box body has a receiving cavity. The pole coil packaging assembly is fixed to the receiving cavity.

[0024] Through the above solution, the box body can seal and protect the pole coil packaging assembly and the pole coil to prevent the pole coil packaging assembly and the pole coil from being damaged by external factors.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification, claims and drawings of this application are intended to cover non-exclusive inclusions.

[0045] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiments" in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0046] The directional words appearing in the following description are all directions shown in the drawings, and do not limit the specific structure of the present application. For example, in the description of the present application, the directions or positional relationships indicated by the terms "center", "length", "width", "thickness", "inside", "outside", "axial", "radial", "circumferential", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application.

[0047] Furthermore, the expressions indicating directions such as the X direction used to illustrate the operation and construction of the components of the present embodiment are not absolute but relative, and although these indications are appropriate when the components are in the positions shown in the figures, when these positions are changed, these directions should be interpreted differently to correspond to the changes.

[0048] In addition, the terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0049] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, the "connection" or "connection" of a mechanical structure may refer to a physical connection. For example, the physical connection may be a fixed connection, such as a fixed connection through a fixing member, such as a fixed connection through a screw, bolt or other fixing member; the physical connection may also be a detachable connection, such as a mutual snap-on or snap-fit ​​connection; the physical connection may also be an integral connection, such as a connection formed by welding, bonding or integral molding. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0050] In the prior art, in the process of packaging or transporting the electrode, the electrode ear is easily damaged, resulting in the quality of the electrode ear failing to meet the requirements, affecting the use of the electrode. Specifically, based on the packaging process of the electrode: the electrode is wound on a reel to form a pole roll on the reel; a protective plate is put on the peripheral wall of the reel from both ends of the reel, and the protective plate is located on the end side of the pole roll. Based on the above process, the inventor found that the reel is prone to shaking during the process of putting the protective plate on the reel, and the magnitude of the force applied to the protective plate is difficult to accurately control, resulting in the position of the protective plate on the reel being difficult to determine, and the protective plate is easy to press against the electrode ear, causing damage to the electrode ear.

[0051] Based on this, an embodiment of the present application provides a pole roll packaging assembly, which limits the position of the protection plate on the roll by means of the abutment between the limiting portion in the limiting member and the end surface of the roll.

[0052] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0053] The present application embodiment provides a pole coil packaging assembly 11. Figures 1 to 3The pole roll packaging assembly 11 includes a drum 111, a protective plate 112 and a limiter 113. The drum 111 is used to wind the pole roll 2. The protective plate 112 is sleeved on the peripheral wall of the drum 111 and is located on the end side of the pole roll 2 to protect the pole roll 2. The limiter 113 includes a connecting portion 1131 and a limiter 1132 connected to each other. The connecting portion 1131 is connected to the protective plate 112. The limiter 1132 is used to abut against the end face of the drum 111 to limit the protective plate 112 so that a preset gap exists between the protective plate 112 and the end face of the pole roll 2.

[0054] In this embodiment, when the protection plate 112 is sleeved on the drum 111 and reaches a predetermined position, the limiting portion 1132 can abut against the end face of the drum 111. At this time, the end face of the drum 111 can apply a force to the limiting portion 1132 that is opposite to the pole roll 2 to prevent the limiting portion 1132 from moving in a direction close to the pole roll 2. In addition, the limiting portion 1132 can apply a force to the connecting portion 1131 that is opposite to the pole roll 2 to prevent the connecting portion 1131 from moving in a direction close to the pole roll 2. The connecting portion 1131 can apply a force to the protection plate 112 that is opposite to the pole roll 2 to prevent the protection plate 112 from moving in a direction close to the pole roll 2. In other words, the abutment between the limiting portion 1132 and the end face of the drum 111 can maintain the protection plate 112 at a predetermined position with a preset gap with the end face of the pole roll 2. In this way, the protection plate 112 will not contact the pole roll 2 and damage the pole ear.

[0055] The shape and material of the reel 111 can be the same as those in the prior art. The method of winding the pole coil 2 on the reel 111 can also be the same as those in the prior art. The above contents will not be described in detail here.

[0056] The protective plate 112 may include a first protective plate and a second protective plate. The first protective plate and the second protective plate are both sleeved on the reel 111 and have an interference fit with the reel 111. In this way, there can be mutual friction between the first protective plate and the reel 111, and between the second protective plate and the reel 111. The existence of friction will prevent the first protective plate and the second protective plate from moving or swinging on the reel 111 at will, thereby avoiding damage to the pole ear. The first protective plate can be located on the first end side of the pole roll 2, and the second protective plate can be located on the second end side of the pole roll 2. In this way, the first protective plate and the second protective plate can buffer the external force at both ends of the pole roll 2, thereby avoiding external force from directly acting on the pole roll 2 and damaging the pole ear.

[0057] The shape of the protection plate 112 may be polygonal, arc-shaped or irregular, etc. The material of the protection plate 112 may be polypropylene (PP), polyethylene (PE), polystyrene (PS), acrylonitrile-styrene-butadiene copolymer (ABS), polyethylene terephthalate (PET) or foam, etc. The embodiment of the present application does not specifically limit the shape and material of the protection plate 112.

[0058] The preset gap between the protection plate 112 and the end surface of the pole coil 2 can be set between 15 mm and 40 mm. In this way, the protection plate 112 does not abut against the pole lug when not under force, and can also have a certain deformation space when under force, rather than directly abutting against the pole lug.

[0059] The limiting member 113 may include a first limiting member and a second limiting member. The first limiting member may be located on the same side as the first protective plate to limit the first protective plate. The second limiting member may be located on the same side as the second protective plate to limit the second protective plate.

[0060] The material of the limiting member 113 may be polyethylene terephthalate (PET), polyethylene (PVE), PP or ABS, etc. The embodiment of the present application does not specifically limit the specific material of the limiting member 113.

[0061] The connection portion 1131 and the limiting portion 1132 may be connected in one piece or assembled. When the limiting portion 1132 and the connection portion 1131 are assembled and connected, for example, the specific manner between the two may be screw connection or plug connection, etc., which is not specifically limited in the embodiment of the present application.

[0062] There may be multiple ways of connecting the connection portion 1131 to the protection plate 112. In one connection mode, when the material of the protection plate 112 is PP, PE, PS, ABS or PET, the connection portion 1131 may be integrally connected to the protection plate 112. In another connection mode, when the material of the protection plate 112 is foam, the connection portion 1131 may be assembled and connected to the protection plate 112. Specifically, the connection portion 1131 may include a connection hook, and a hook groove adapted to the connection hook may be provided on the side of the protection plate 112 facing the pole roll 2, and the connection hook may be embedded in the hook groove so that the connection portion 1131 is hooked to the protection plate 112.

[0063] In the above embodiment, the limiting portion 1132 may be in various forms. For ease of understanding, possible forms of the limiting portion 1132 are exemplarily described below.

[0064] In some embodiments, please combine Figure 1 and Figures 4 to 6 The limiting portion 1132 is configured as a limiting block 1132a, and the surface of the limiting block 1132a abuts against the end surface of the reel 111. In other words, the limiting portion 1132 is configured as a block structure, and the block structure abuts against the end surface of the reel 111.

[0065] In this embodiment, the end surface of the winding drum 111 can apply a force to the surface of the limit block 1132a to move away from the pole winding 2. The limit block 1132a can apply a force to the protection plate 112 to move away from the pole winding 2 through the connecting portion 1131, so that the protection plate 112 does not move toward the pole winding 2.

[0066] The limiting block 1132a may have a variety of shapes, such as cylindrical, prism-shaped, or irregular, etc. The embodiment of the present application does not specifically limit the specific shape of the limiting block 1132a.

[0067] In other embodiments, please combine Figure 1 and Figures 7 to 9 The limiting portion 1132 is configured as a limiting ring 1132b, and the annular surface of the limiting ring 1132b abuts against the end surface of the reel 111. In other words, the limiting portion 1132 is configured as an annular structure, and the annular structure abuts against the end surface of the reel 111.

[0068] In this embodiment, the end surface of the winding drum 111 can exert a force on the annular surface of the limiting ring 1132b to move away from the pole winding 2. The limiting ring 1132b can exert a force on the protection plate 112 to move away from the pole winding 2 through the connecting portion 1131, so that the protection plate 112 does not move toward the direction close to the pole winding 2.

[0069] The limiting ring 1132b may also have a variety of shapes, such as a polygonal ring, a circular ring, or a special-shaped ring, etc. The embodiment of the present application does not specifically limit the specific shape of the limiting ring 1132b.

[0070] In some other embodiments, please combine Figure 1 and Figures 10 to 12 The limiting portion 1132 is configured as a limiting plate 1132c, and the plate surface of the limiting plate 1132c abuts against the end surface of the reel 111. In other words, the limiting portion 1132 can be configured as a plate-like structure, and the plate-like structure abuts against the end surface of the reel 111.

[0071] In this embodiment, the end surface of the winding drum 111 can apply a force to the plate surface of the limiting plate 1132c to move away from the pole winding 2. The limiting plate 1132c can apply a force to the protection plate 112 to move away from the pole winding 2 through the connecting portion 1131, so that the protection plate 112 does not move toward the direction close to the pole winding 2.

[0072] The limiting plate 1132c may also be in various shapes, such as a polygonal plate, a circular plate, or a special-shaped plate. The embodiment of the present application does not specifically limit the specific form of the limiting plate 1132c.

[0073] On the basis of the above embodiments, further, based on the different forms of the limiting portion 1132, the end surface of the reel 111 can also be set in various forms. The possible forms of the end surface of the reel 111 are exemplarily described below.

[0074] In some embodiments, the end surface of the reel 111 may be set as a plane. The limiting block 1132a, the limiting ring 1132b or the limiting plate 1132c may abut against the plane (not shown in the figure).

[0075] In this embodiment, the plane can apply force to the limit block 1132a, the limit ring 1132b or the limit plate 1132c to prevent the limit block 1132a, the limit ring 1132b or the limit plate 1132c from moving toward the direction approaching the pole roll 2.

[0076] In other embodiments, please combine Figures 4 to 6 When the limiting portion 1132 is configured as a limiting block 1132a, the end surface of the reel 111 is provided with a limiting groove AC adapted to the limiting block 1132a. The limiting block 1132a can be embedded in the limiting groove AC, and the surface of the limiting block 1132a can abut against the groove wall of the limiting groove AC.

[0077] In this embodiment, the groove wall of the limiting groove AC can apply force to the surface of the limiting block 1132a to prevent the limiting block 1132a from moving in the direction close to the pole roll 2. In addition, the groove wall of the limiting groove AC can also apply force to the surface of the limiting block 1132a to prevent the limiting block 1132a from sliding on the end surface of the reel 111. When the limiting block 1132a does not slide on the end surface of the reel 111, the connecting portion 1131 will not rotate with the sliding of the limiting block 1132a, and the protective plate 112 will not rotate on the peripheral wall of the reel 111 with the rotation of the connecting portion 1131, which is conducive to improving the stability of the protective plate 112 being sleeved on the reel 111.

[0078] Specifically, the groove wall of the limiting groove AC may include a bottom wall and a side wall. The bottom wall refers to a wall opposite to the opening direction of the limiting groove AC, and the side wall refers to a wall adjacent to the opening direction of the limiting groove AC. The bottom wall can apply a force to the limiting block 1132a to prevent the limiting block 1132a from moving in a direction close to the pole roll 2. The side wall can apply a force to the limiting block 1132a to prevent the limiting block 1132a from sliding on the end surface of the reel 111.

[0079] The arrangement form of the limiting groove AC can match the arrangement form of the limiting block 1132a. For example, when the limiting block 1132a is arranged in a quadrangular prism shape, the limiting groove AC can be arranged in a rectangular parallelepiped groove.

[0080] In some other embodiments, see Figures 7 to 12 When the limiting portion 1132 is configured as a limiting ring 1132b or a limiting plate 1132c, a limiting protrusion (not shown) is provided on the surface of the limiting portion 1132 facing the end surface of the reel 111. A limiting hole K adapted to the limiting protrusion is provided on the end surface of the reel 111. The limiting protrusion can be embedded in the limiting hole K, and the surface of the limiting protrusion can abut against the hole wall of the limiting hole K.

[0081] In this embodiment, on the basis that the limiting ring 1132b or the limiting plate 1132c abuts against the end surface of the reel 111, the hole wall of the limiting hole K can abut against the surface of the limiting protrusion and apply force to the limiting protrusion to prevent the limiting portion 1132 from moving in the direction close to the pole roll 2. In addition, the hole wall of the limiting hole K can also abut against the surface of the limiting protrusion and apply force to the limiting protrusion to prevent the limiting ring 1132b or the limiting plate 1132c from sliding on the end surface of the reel 111. When the limiting ring 1132b or the limiting plate 1132c does not slide on the end surface of the reel 111, the connecting portion 1131 will not rotate with the sliding of the limiting ring 1132b or the limiting plate 1132c, and the protective plate 112 will not rotate on the peripheral wall of the reel 111 with the rotation of the connecting portion 1131, which is conducive to improving the stability of the protective plate 112 sleeved on the reel 111.

[0082] Specifically, the hole wall of the limiting hole K may include a bottom wall and a side wall. The bottom wall refers to a wall opposite to the opening direction of the limiting hole K, and the side wall refers to a wall adjacent to the opening direction of the limiting hole K. The bottom wall can apply a force to the limiting protrusion to prevent the limiting block 1132a from moving in a direction close to the pole roll 2. The side wall can apply a force to the limiting protrusion to prevent the limiting block 1132a from sliding on the end surface of the reel 111.

[0083] The shape of the limiting protrusion can be the same as the shape of the aforementioned limiting block 1132a. It is not repeated here, and the shape of the limiting hole K can match the shape of the limiting protrusion. The shapes of the limiting protrusion and the limiting hole K are not specifically limited in the embodiment of the present application.

[0084] In the above embodiment, the connection portion 1131 may be in various forms. For ease of understanding, an exemplary description is given below.

[0085] In some embodiments, please combine Figure 1 , Figure 4 , Figure 7 and Fig.10 The connection portion 1131 is configured as a connection rod 1131 a, and the connection rod 1131 a is connected to the protection plate 112. That is, the connection portion 1131 is configured as a rod-shaped structure, and the rod-shaped structure is connected to the protection plate 112.

[0086] In this embodiment, when the limiting portion 1132 is abutted by the end surface of the winding drum 111, the limiting portion 1132 can apply a force to the connecting rod 1131a that is opposite to the pole winding 2. The connecting rod 1131a can apply a force to the protective plate 112 that is opposite to the pole winding 2 to prevent the protective plate 112 from moving toward the pole winding 2, thereby preventing the protective plate 112 from abutting against the pole winding 2 and damaging the pole ear.

[0087] The connecting rod 1131a may have a variety of shapes, such as cylindrical, prism, wavy or spiral, etc. The embodiment of the present application does not specifically limit the shape of the connecting rod 1131a.

[0088] In other embodiments, please combine Figure 1 , Figure 5 , Figure 8 and Fig.11 The connection portion 1131 is configured as a connection plate 1131 b, and the connection plate 1131 b is connected to the protection plate 112. That is, the connection portion 1131 is configured as a plate-like structure, and the plate-like structure is connected to the protection plate 112.

[0089] In this embodiment, when the limiting portion 1132 is abutted by the end surface of the winding drum 111, the limiting portion 1132 can apply a force to the connecting plate 1131b that is opposite to the pole winding 2. The connecting plate 1131b can apply a force to the protective plate 112 that is opposite to the pole winding 2 to prevent the protective plate 112 from moving toward the direction close to the pole winding 2, thereby preventing the protective plate 112 from abutting against the pole winding 2 and damaging the pole ear.

[0090] The connecting plate 1131b may have a variety of shapes, such as arc shape or plane shape, etc. The embodiment of the present application does not specifically limit the shape of the connecting plate 1131b.

[0091] In some other embodiments, please combine Figure 1 , Figure 6 , Fig. 9 and Fig.12The connection portion 1131 is configured as a connection tube 1131 c, and the connection tube 1131 c is connected to the protection plate 112. In other words, the connection portion 1131 is configured as a cylindrical structure, and the cylindrical structure is connected to the protection plate 112.

[0092] In this embodiment, when the limiting portion 1132 is abutted by the end surface of the winding drum 111, the limiting portion 1132 can apply a force to the connecting tube 1131c that is opposite to the pole winding 2. The connecting tube 1131c can apply a force to the protective plate 112 that is opposite to the pole winding 2 to prevent the protective plate 112 from moving toward the pole winding 2, thereby preventing the protective plate 112 from abutting against the pole winding 2 and damaging the pole ear.

[0093] It should be noted that the above-mentioned various forms of connecting parts 1131 may or may not be in contact with the peripheral wall of the reel 111. For example, when the connecting part 1131 is set as a connecting tube 1131c, the inner diameter of the connecting tube 1131c can be set to be adapted to the outer diameter of the reel 111, and the connecting tube 1131c can be sleeved on the peripheral wall of the reel 111 and contact the peripheral wall of the reel 111. When the connecting part 1131 is set as a connecting rod 1131a or a connecting plate 1131b, the connecting rod 1131a or the connecting plate 1131b can be distributed at intervals on the peripheral side of the reel 111 and not contact the peripheral wall of the reel 111.

[0094] Further, based on the various forms of the connection portion 1131, it can be seen that the connection portion 1131 can include a first end face, a second end face, and an intermediate portion between the first end face and the second end face in the axial direction X of the reel 111. Based on the form of the connection portion 1131, the position where the limit portion 1132 and the protection plate 112 are connected to the connection portion 1131 can be various. For ease of understanding, an exemplary description is given below.

[0095] For some examples, see Figure 2 The first end surface is connected to the protection plate 112 , and the second end surface is connected to the limiting portion 1132 .

[0096] In this example, when the limiting portion 1132 is abutted by the end face of the winding drum 111 , the second end face can apply a force to the connecting portion 1131 facing away from the pole winding 2 , and the first end face can apply a force to the protective plate 112 facing away from the pole winding 2 to limit the protective plate 112 .

[0097] Specifically, when the material of the protection plate 112 is PP, PE, PS, S or PET, the first end surface may be connected to the protection plate 112 , and the second end surface may be connected to the limiting portion 1132 .

[0098] For other examples, see Figure 3The middle part of the connecting portion 1131 is connected to the protection plate 112 , and the first end surface or the second end surface is connected to the limiting portion 1132 .

[0099] In this example, when the limiting portion 1132 is abutted by the end face of the drum 111, the first end face or the second end face can apply a force to the connecting portion 1131 that is away from the pole roll 2, and the middle part of the drum 111 can apply a force to the protective plate 112 that is away from the pole roll 2 to limit the protective plate 112.

[0100] Specifically, when the material of the protection plate 112 is foam, the middle portion of the connection portion 1131 is connected to the protection plate 112 , and the first end surface or the second end surface is connected to the limiting portion 1132 .

[0101] In the above two examples, please continue to see Figures 1 to 3 A connecting ring may also be connected to the connecting portion 1131 , and the connecting ring may connect the connecting portion to the protective plate 112 .

[0102] In the above embodiment, the protection plate 112 may be configured as follows to protect the pole winding 2 .

[0103] In some embodiments, see Figures 1 to 3 In the axial direction X of the winding drum 111 , within the same projection plane, the projection area of ​​the protection plate 112 completely covers the projection area of ​​the pole winding 2 .

[0104] In this embodiment, in the axial direction X of the winding drum 111 , the protection plate 112 can completely cover the end surface of the pole winding 2 to prevent the pole ear from being damaged by external force.

[0105] The projection surface in this embodiment refers to a surface perpendicular to the axial direction X of the reel 111. The projection surface may be a virtual surface. The projection surface may be coplanar with the cross section of the reel 111, the pole reel 2, or the protective plate 112, or may be coplanar with other surfaces other than the reel 111, the pole reel 2, or the protective plate 112. The embodiment of the present application does not impose any specific restrictions on the projection surface.

[0106] In some embodiments, the pole roll packaging assembly 11 further includes a packaging bag. The packaging bag may be a packaging film including a plastic layer and an aluminum layer. The packaging bag is sleeved over the roll 111, the protective plate 112 and the pole roll 2. Figure 2 A supporting boss TT is provided on the side of the protection plate 112 facing away from the pole coil 2, and the supporting boss TT is used to support the packaging bag.

[0107] After the packaging bag wraps the roll 111, the protection plate 112 and the pole roll 2, the packaging bag needs to be evacuated to prevent environmental factors from affecting the pole roll 2. However, during the process of evacuating the packaging bag, the inventor found that the packaging bag would deform toward the pole ear, squeezing the pole ear.

[0108] Based on this, in this embodiment, during the vacuum operation on the packaging bag, the supporting boss TT can support the packaging bag, prevent the packaging bag from deforming toward the tab, and avoid the packaging bag from damaging the tab.

[0109] Among them, the edge parts of the supporting boss TT can all be provided with arc chamfers, so that when the supporting boss TT supports the packaging bag, the pressure at the contact part between the edge part of the supporting boss TT and the packaging bag is relatively small, and the edge part of the supporting boss TT is not easy to damage the packaging bag.

[0110] In some embodiments, see Figure 2 The surface of the protection plate 112 is provided with reinforcing ribs J.

[0111] In this embodiment, the reinforcing ribs J can increase the thickness of a portion of the protection plate 112 , thereby increasing the strength of the protection plate 112 .

[0112] The reinforcing ribs J may be arranged in a strip structure and / or an annular structure. A plurality of reinforcing ribs J may be arranged radially and evenly on the surface of the protective plate 112 with the axis of the reel 111 as the center.

[0113] The reinforcing rib J can be disposed on the plate surface of the protection plate 112 facing the pole coil 2, or on the plate surface of the protection plate 112 facing away from the pole coil 2, or on both the plate surface of the protection plate 112 facing the pole coil 2 and the plate surface facing away from the pole coil 2. The present application embodiment does not specifically limit this.

[0114] Exemplarily, when the reinforcing rib J is arranged on the plate surface of the protective plate 112 facing away from the pole roll 2, specifically, the middle portion of the protective plate 112 facing away from the pole roll 2 can be concave, and the reinforcing rib J can be arranged in the concave portion, so that when the supporting boss TT supports the packaging bag, the reinforcing rib J is not easy to damage the aforementioned packaging bag.

[0115] Based on the pole coil packaging assembly 11 provided in the above-mentioned embodiments, it should be noted that, compared with the pole coil packaging assembly in the prior art, the pole coil packaging assembly 11 provided in the embodiment of the present application can prevent environmental factors from affecting the pole coil only by using a packaging bag, and does not need to wrap a protective film on the outer surface of the pole coil 2. In this way, the packaging cost of the pole coil 2 can be reduced.

[0116] The present application embodiment also includes a packaging box 1. Fig.13 The packaging box 1 comprises a box body 12 and the pole coil packaging assembly 11. The box body 12 has a receiving cavity. The pole coil packaging assembly 11 is fixed in the receiving cavity.

[0117] In this embodiment, the box body 12 can seal and protect the aforementioned pole coil packaging assembly 11 and pole coil 2 to prevent the pole coil packaging assembly 11 and pole coil 2 from being damaged by external components.

[0118] The box body 12 may be configured to be in a rectangular parallelepiped or cylindrical shape, etc. The accommodating cavity may also be configured to be in a rectangular parallelepiped or cylindrical shape, etc. The embodiment of the present application does not specifically limit the shape of the box body 12 and the shape of the accommodating cavity.

[0119] When the pole roll packaging assembly 11 is fixed to the accommodating cavity, illustratively, the cavity wall of the accommodating cavity may be provided with a fixing plate for fixing the reel 111, and the reel 111 of the roll packaging assembly 11 may be fixed to the fixing plate to be fixed to the accommodating cavity.

[0120] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
