Description
Technical Field
[0001] The present application relates to the technical field of polar coil packaging, and in particular to a packaging box. Background Art
[0002] The pole roll refers to the winding core formed after the pole piece is wound. Before transporting the pole roll, it needs to be packed in a packaging box to ensure the quality of the pole roll.
[0003] However, based on the structure of the existing packaging box, after the pole coil is packaged in the packaging box, the pole coil will move or swing in the packaging box. During the movement or swinging process, the pole coil is easily damaged. Utility Model Content
[0004] The embodiment of the present application provides a packaging box to solve the problem that the pole coil is easily moved or swung in the existing packaging box, thereby achieving the limitation of the pole coil.
[0005] The embodiment of the present application provides a packaging box. The packaging box is used to package a pole coil. The packaging box includes a box body, a reel and a limit block. The box body has a receiving cavity. The reel is received in the receiving cavity. The reel is used to wind the pole coil. The limit block is connected to the cavity wall of the receiving cavity and abuts against the end face of the reel. The limit block is used to limit the reel in the axial direction of the reel.
[0006] Considering the technical problem that the pole coil is easy to move or swing in the packaging box when the pole coil is packaged in the packaging box of the prior art. The embodiment of the present application sets a limit block on the cavity wall of the accommodating cavity in the box body, and sets the limit block to be able to abut against the end face of the reel, so that the limit block can apply force to the end face of the reel to prevent the reel from moving toward the limit block in the axial direction and prevent the reel from swinging in other directions. When the reel does not move or swing, the pole coil wound on the reel will not move or swing with the reel, the pole piece in the pole coil will not be misplaced, and the pole coil will not collide with other components in the box body, so the quality of the pole coil can be guaranteed.
[0007] In some optional arrangements, the limit block includes a first limit block, the accommodating cavity includes a limit wall opposite to the first limit block, the first limit block abuts against the first end surface of the reel, and the limit wall abuts against the second end surface of the reel.
[0008] Through the above scheme, the first limit block can apply force to the first end face of the reel to prevent the reel from moving toward the first limit block in the axial direction or swinging in the radial direction. In addition, the limit wall can apply force to the second end face of the reel to prevent the reel from moving toward the limit wall in the axial direction or swinging in the radial direction.
[0009] In some optional configurations, the limit block includes a first limit block and a second limit block that are arranged opposite to each other, the first limit block abuts against the first end surface of the reel, and the second limit block abuts against the second end surface of the reel.
[0010] Through the above scheme, the first limit block can apply force to the first end face of the reel to prevent the reel from moving toward the first limit block in the axial direction or swinging in the radial direction. In addition, the second limit block can apply force to the second end face of the reel to prevent the reel from moving toward the second limit block in the axial direction or swinging in the radial direction.
[0011] In some optional configurations, when the first limit block abuts against the first end surface of the reel and the limit wall abuts against the second end surface of the reel, the distance L between the first limit block and the limit wall is 11 , and the length of the roll L 01 The distance between them is configured to satisfy: 0 mm ≤ L 01 -L 11 ≤3 mm.
[0012] Through the above scheme, in the process of the roll being clamped between the first limit block and the limit wall, under the squeezing action of the roll, the first limit block, the limit wall, or the first limit block and the limit wall can undergo a total deformation of less than or equal to 3 mm in the direction away from the roll, and this deformation will increase the contact force of the first limit block and the limit wall on the roll.
[0013] In some optional configurations, when the first limit block abuts against the first end surface of the reel and the second limit block abuts against the second end surface of the reel, the distance L between the first limit block and the second limit block is 12 , and the length of the roll L 01 The distance between them is configured to satisfy: 0 mm ≤ L 01 -L 12 ≤3 mm.
[0014] Through the above scheme, in the process of the roll being clamped between the first limit block and the second limit block, under the squeezing action of the roll, the first limit block, the second limit block, or the first limit block and the second limit block can undergo a total deformation of less than or equal to 3 mm in the direction away from the roll, and this deformation will increase the contact force of the first limit block and the second limit block on the roll.
[0015] In some optional configurations, the roll enters the accommodating chamber along a first direction, wherein the first direction is perpendicular to the axis of the roll. In the second direction, the size L of the stop block is 21 The size of the roll is L 02 Configured to satisfy: L 21 ≥L 02 The second direction is perpendicular to the axis direction of the reel and perpendicular to the first direction.
[0016] By means of the above solution, when viewed from the axial direction of the reel, in the second direction, the stop block can have a sufficient size to abut against the end surface of the reel. In this way, the reel can slide a large distance along the second direction on the stop block without falling. The reliability of the stop block abutting against the reel can be improved.
[0017] In some optional configurations, the roll enters the accommodating chamber along a first direction, wherein the first direction is perpendicular to the axis direction of the roll. In the first direction, the size L of the contact portion between the stop block and the roll is 22 , and the size of the roll L 03 Configured to satisfy: 1 / 2≤L 22 / L 03 ≤2 / 3.
[0018] With the above solution, when the limit block contacts the end face of the roll, the roll needs to slide at least half of the size on the limit block in the first direction before it can slide off the limit block, and the reliability of the contact between the limit block and the roll can be guaranteed. When the roll is taken out of the accommodating cavity, the roll can be separated from the limit block by sliding at most 1 / 2 of the size on the limit block in the opposite direction of the first direction, so that the roll can be taken out of the accommodating cavity.
[0019] In some optional configurations, the stopper includes a wood layer. Alternatively, the stopper includes a foam layer. Alternatively, the stopper includes a stacked wood layer and a foam layer, the wood layer is connected to the cavity wall of the accommodating cavity, and the foam layer is connected to the side of the wood layer facing away from the cavity wall of the accommodating cavity. Alternatively, the stopper includes a stacked wood layer and a tape layer, the wood layer is connected to the cavity wall of the accommodating cavity, and the tape layer is connected to the side of the wood layer facing away from the cavity wall of the accommodating cavity.
[0020] According to the above solution, when the stop block includes a foam layer or a tape layer, the stop block can have a certain flexibility without damaging other components, wherein the other components can be a packaging roll and a packaging bag of the pole roll.
[0021] In some optional configurations, the packaging box further includes a reinforcement member. The reinforcement member is connected to the cavity wall of the accommodating cavity and is close to the limiting block. The reinforcement member is used to reinforce the cavity wall of the accommodating cavity.
[0022] Through the above solution, the strength of the cavity wall connected to the reinforcing member in the accommodating cavity can be improved. In this way, when the reel abuts against the limit block and the limit block abuts against the cavity wall, the cavity wall is not easily deformed or damaged.
[0023] In some optional configurations, the packaging box further includes a first limiting plate and a second limiting plate, both of which are slidably connected to the cavity wall of the accommodating cavity, and the plate surface of the first limiting plate and the plate surface of the second limiting plate are coplanar. The first limiting plate and the second limiting plate both abut against the circumference of the roll to limit the roll in the radial direction of the roll.
[0024] Through the above solution, the first limit plate and the second limit plate can apply force to the circumference of the drum to prevent the drum from moving in the radial direction. When the drum does not move in the radial direction, the pole roll wound on the drum will not move in the radial direction of the drum, and the pole roll will not collide with other components in the box, so the quality of the pole roll can be guaranteed.
[0025] In some optional arrangements, the reel includes a first limiting portion and a second limiting portion, and a winding area is provided between the first limiting portion and the second limiting portion, and the winding area is used for winding the pole roll.
[0026] Through the above solution, the first limit part and the second limit part can cooperate with the winding device so that each layer in the pole roll can be stacked in the winding area. In this way, after the pole roll is formed, the end surface of the pole roll can be relatively flat, the pole roll is not easily damaged by other components, and the quality of the pole roll can be guaranteed.

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.
[0045] 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.
[0046] The present application embodiment provides a packaging box 1. The packaging box 1 is used to package a pole coil 2. Figure 1 and Figure 2 The packaging box 1 comprises a box body 11, a reel 12 and a stopper 13. The box body 11 has a receiving cavity. The reel 12 is received in the receiving cavity. The reel 12 is used to wind the pole reel 2. The stopper 13 is connected to the cavity wall of the receiving cavity and abuts against the end face of the reel 12. The stopper 13 is used to stop the reel 12.
[0047] In this embodiment, the surface of the limit block 13 facing the drum 12 can contact the end surface of the drum 12, and the limit block 13 can apply force to the end surface of the drum 12 to prevent the drum 12 from moving or swinging. Specifically, the limit block 13 can apply abutment force parallel to the axial direction X of the drum to the drum 12 by contacting the end surface of the drum 12, and the abutment force can prevent the drum 12 from moving in the axial direction. At the same time, the limit block 13 can also apply a friction force parallel to the radial direction of the drum 12 to the drum 12 by contacting the end surface of the drum 12, and the friction force can prevent the drum 12 from swinging in the radial direction. When the drum 12 does not move or swing, the pole roll 2 wound on the drum 12 will not move or swing with the drum 12, the pole pieces in the pole roll 2 will not be misplaced, and the pole roll 2 will not collide with other components in the box 11, and the quality of the pole roll 2 can be guaranteed.
[0048] The box body 11 can be formed into a rectangular or cylindrical shape by splicing a plurality of box walls. Specifically, adjacent box walls can be spliced by a plurality of L-shaped tongues. In addition, a plurality of support rods can be arranged at intervals on the wall surface of the box wall, and the plurality of support rods are used to support the box wall to prevent the box wall from deforming into the accommodation cavity and pressing against the pole coil 2.
[0049] The accommodating cavity formed by splicing a plurality of box walls may also be in the shape of a cuboid or a cylinder. The embodiment of the present application does not specifically limit the shape of the accommodating cavity.
[0050] The winding drum 12 may be an annular drum with a through cavity. A desiccant may be placed in the inner cavity of the winding drum 12, and the desiccant may absorb moisture in the packaging box 1 to prevent the moisture from affecting the pole coil 2. The method of winding the pole coil 2 on the winding drum 12 may be the same as the prior art, and will not be described in detail here.
[0051] After the pole winding 2 is wound on the winding drum 12, it may be formed into an annular winding.
[0052] When the winding drum 12 and the pole roll 2 are located in the accommodating cavity, the pole roll 2 may or may not be in contact with the cavity wall of the accommodating cavity. For example, in the radial direction of the pole roll 2, when the size of the accommodating cavity is larger than the size of the pole roll 2, the pole roll 2 does not contact the cavity wall of the accommodating cavity. In the radial direction of the pole roll 2, when the size of the accommodating cavity is the same as the size of the pole roll 2, the pole roll 2 contacts the cavity wall of the accommodating cavity. Among them, when the pole roll 2 contacts the cavity wall of the accommodating cavity, the cavity wall of the accommodating cavity can restrain the pole roll 2 and prevent the pole roll 2 from loosening.
[0053] The limiting block 13 may be in a cube, a cuboid, or a cylinder, etc. The embodiment of the present application does not specifically limit the specific shape of the limiting block 13 , as long as the limiting block 13 can abut against the end surface of the reel 12 .
[0054] There may be multiple ways to connect the stop block 13 to the cavity wall of the accommodating cavity. For example, in one connection method, the stop block 13 and the cavity wall of the accommodating cavity may be connected by gluing. In another connection method, the stop block 13 and the cavity wall of the accommodating cavity may be connected by screws or rivets. The embodiment of the present application does not specifically limit the way in which the stop block 13 is connected to the cavity wall of the accommodating cavity.
[0055] In the above embodiment, there are many ways for the limit block 13 to abut against the end surface of the reel 12. The following is an exemplary description of possible abutment methods.
[0056] In some embodiments, see Figure 3 The limit block 13 includes a first limit block 131 , the accommodating cavity includes a limit wall B opposite to the first limit block 131 , the first limit block 131 abuts against the first end surface of the reel 12 , and the limit wall B abuts against the second end surface of the reel 12 .
[0057] In this embodiment, the first limit block 131 can apply an abutting force to the first end surface of the reel 12 to prevent the reel 12 from moving toward the first limit block 131 in the axial direction. At the same time, the first limit block 131 can apply a friction force to the first end surface of the reel 12 to prevent the reel 12 from swinging in other directions. The limit wall B can apply an abutting force to the second end surface of the reel 12 to prevent the reel 12 from moving toward the limit wall B in the axial direction. At the same time, the limit wall B can apply a friction force to the second end surface of the reel 12 to prevent the reel 12 from swinging in other directions. In other words, the reel 12 can be clamped between the first limit block 131 and the limit wall B to be limited by the first limit block 131 and the limit wall B.
[0058] In other embodiments, see Figure 4 The limit block 13 includes a first limit block 131 and a second limit block 132 which are arranged opposite to each other. The first limit block 131 abuts against the first end surface of the reel 12 , and the second limit block 132 abuts against the second end surface of the reel 12 .
[0059] In this embodiment, the manner in which the first limiting block 131 and the second limiting block 132 limit the reel 12 may be similar to the manner in which the first limiting block 131 and the limiting wall B limit the reel 12, which will not be described again here.
[0060] In the above two embodiments, the first end face and the second end face of the reel 12 refer to the two end faces of the reel 12 in the axial direction. Both the first end face and the second end face can be planes. Moreover, both the first end face and the second end face can abut the plane on the limit block 13. In this way, the contact between the first end face and the limit block 13, and the contact between the second end face and the limit block 13 can be the contact between planes. Because the contact between planes has a larger contact area than the contact between planes and lines, or planes and points. Therefore, when the contact between the first end face and the limit block 13, and the contact between the second end face and the limit block 13 are both the contact between planes, the abutment between the first end face and the limit block 13, and the abutment between the second end face and the limit block 13 is more reliable.
[0061] Furthermore, based on the different ways in which the limiting block 13 abuts against the end surface of the reel 12, the size requirements between the first limiting block 131 and the limiting wall B, or between the first limiting block 131 and the second limiting block 132 are different. For ease of understanding, the following is an example.
[0062] In some embodiments, please see Figure 3 When the first limit block 131 abuts against the first end surface of the reel 12 and the limit wall B abuts against the second end surface of the reel 12, the distance L between the first limit block 131 and the limit wall B is 11 , and the length L of the reel 12 01 The distance between them is configured to satisfy: 0 mm ≤ L 01 -L 11 ≤3 mm.
[0063] In this embodiment, during the process of the reel 12 being clamped between the first limit block 131 and the limit wall B, under the squeezing action of the reel 12, the first limit block 131 may be deformed by less than or equal to 3 mm in the direction away from the reel 12, or the limit wall B may be deformed by less than or equal to 3 mm in the direction away from the reel 12, or the first limit block 131 and the limit wall B may be deformed by less than or equal to 3 mm in total in the direction away from the pole roll 2. The above deformation will increase the force applied by the first limit block 131 and the limit wall B on the reel 12, thereby making the reel 12 unable to move or swing, and the pole roll 2 unable to move or swing with the reel 12.
[0064] In other embodiments, please continue to refer to Figure 4 When the first limit block 131 abuts against the first end surface of the reel 12 and the second limit block 132 abuts against the second end surface of the reel 12, the distance L between the first limit block 131 and the second limit block 132 is 12 , and the length L of the reel 12 01 The distance between them is configured to satisfy: 0 mm ≤ L 01 -L12 ≤3 mm.
[0065] In the present embodiment, during the process of the reel 12 being clamped between the first limit block 131 and the second limit block 132, under the squeezing action of the reel 12, the first limit block 131 may be deformed by less than or equal to 3 mm in the direction away from the reel 12, or the second limit block 132 may be deformed by less than or equal to 3 mm in the direction away from the reel 12, or the first limit block 131 and the second limit block 132 may be deformed by less than or equal to 3 mm in total in the direction away from the pole roll 2. The above deformation will increase the force applied by the first limit block 131 and the second limit block 132 on the reel 12, thereby making the reel 12 unable to move or swing, and the pole roll 2 unable to move or swing with the reel 12.
[0066] In the above-mentioned embodiments, considering the reliability of the abutment between the limit block 13 and the reel 12 , the embodiment of the present application further arranges the limit block 13 and the reel 12 as follows.
[0067] In some embodiments, please combine Figure 1 and Figure 5 , the reel 12 enters the accommodating chamber along the first direction Y. The first direction Y is perpendicular to the axis direction X of the reel. In the second direction Z, the size L of the limit block 13 is 21 With reel 12 size L 02 Configured to satisfy: L 21 ≥L 02 The second direction Z is perpendicular to the axial direction X of the roll and perpendicular to the first direction Y.
[0068] In this embodiment, when viewed from the axial direction X of the reel, in the second direction Z, the stopper 13 can have a sufficient size to abut against the end surface of the reel 12. In this way, the reel 12 can slide a large distance on the stopper 13 along the second direction Z without falling. The reliability of the stopper 13 abutting against the reel 12 can be improved.
[0069] In addition, considering the reliability of the limiting block 13 limiting the reel 12 and the convenience of fixing the reel 12 in the accommodating cavity, the embodiment of the present application also arranges the limiting block 13 and the reel 12 as follows.
[0070] In some embodiments, please continue to combine Figure 1 and Figure 5 , the reel 12 enters the accommodating chamber along the first direction Y. The first direction Y is perpendicular to the axis direction X of the reel. In the first direction Y, the size L of the contact portion between the stop block 13 and the reel 12 is 22 , and the size L of the reel 12 03 Configured to satisfy: 1 / 2≤L22 / L 03 ≤2 / 3.
[0071] In the embodiment of the present application, it can be seen from the axial direction X of the reel that the reel 12 can abut against at least 1 / 2 and at most 2 / 3 of the size of the limit block 13 in the first direction Y. In this way, when the limit block 13 abuts against the end face of the reel 12, the reel 12 needs to slide at least half of the size on the limit block 13 in the first direction Y to slide off the limit block 13, and the reliability of the abutment between the limit block 13 and the reel 12 can be guaranteed. When the reel 12 is taken out from the accommodating chamber, relative to the entire end face of the reel 12 abutting against the limit block 13, the reel 12 needs to slide on the limit block 13 in the opposite direction of the first direction Y by at least 1 / 2 and at most 2 / 3 of the size of the limit block 13 to be able to disengage from the limit block 13, so as to facilitate the reel 12 to be taken out of the accommodating chamber.
[0072] In the above two embodiments, the reason why the reel 12 enters the accommodating chamber along a direction perpendicular to the axial direction X of the reel is as follows:
[0073] First, since the length of the reel 12 and the pole roll 2 are relatively long (greater than 1 meter), if the reel 12 enters the accommodating cavity along the axial direction, at least one end of the reel 12 is difficult to control, the reel 12 is prone to tilt, and the pole roll 2 is prone to contact the box wall of the box body 11 as the reel 12 tilts and is damaged.
[0074] Secondly, if the winding drum 12 enters the accommodating cavity along the axial direction, the pole roll 2 is easily affected by gravity or inertia, and the pole pieces in the pole roll 2 are easily misaligned, affecting the quality of the pole roll 2.
[0075] Therefore, the reel 12 needs to enter the accommodating chamber along a direction perpendicular to the axial direction X of the reel (the radial direction of the reel 12 ).
[0076] It should be noted that when the reel 12 enters the accommodating cavity along the first direction Y, part of the wall of the box body 11 needs to be removed so that the accommodating cavity has a cavity opening, so that the reel 12 and the pole coil 2 can enter the accommodating cavity from the cavity opening.
[0077] In the above embodiments, the materials of the stopper 13 can be multiple. Based on the different materials of the stopper 13, the stopper 13 can be set as one layer or multiple layers. For ease of understanding, the possible materials of the stopper 13 are exemplarily described below.
[0078] In some examples, the stopper 13 includes a wood layer.
[0079] In this example, the wooden limiting block 13 is directly connected to the cavity wall of the accommodating cavity and abuts against the end surface of the reel 12 to apply force to the reel 12 .
[0080] In another example, the limiting block 13 includes a foam layer.
[0081] In this example, the foam limiting block 13 is directly connected to the cavity wall of the accommodating cavity and abuts against the end surface of the reel 12 to apply force to the reel 12 .
[0082] In some other examples, the stopper 13 includes a laminated wood layer and a foam layer, wherein the wood layer is connected to the cavity wall of the accommodating cavity, and the foam layer is connected to the side of the wood layer facing away from the cavity wall of the accommodating cavity. In other words, the stopper 13 is provided with two layers.
[0083] In this example, the foam layer abuts against the end surface of the roll 12 to apply force to the roll 12 .
[0084] The wood layer and the foam layer may be stacked in the thickness direction, may be bonded together, or may be connected together by other components (eg, rivets), which is not specifically limited in the present application.
[0085] In some other examples, the stopper 13 includes a laminated wood layer and a tape layer, wherein the wood layer is connected to the cavity wall of the accommodating cavity, and the tape layer is connected to the side of the wood layer facing away from the cavity wall of the accommodating cavity. That is, the stopper 13 is provided with two layers.
[0086] In this example, the tape layer abuts against the end surface of the reel 12 to apply force to the reel 12 .
[0087] The wood layer and the foam layer may also be stacked in the thickness direction. The connection method of the wood layer and the tape layer may be similar to the connection method of the wood layer and the tape layer, which will not be described in detail here.
[0088] It should be noted that, in the above examples, when the limit block 13 includes a foam layer or a tape layer, the limit block 13 is not easy to damage other components in the packaging box 1. For example, the other components may be an aluminum-plastic film. Specifically, before the reel 12 and the pole roll 2 enter the accommodating cavity, it is necessary to first place an aluminum-plastic film in the accommodating cavity, and then place the pole roll 2 of the reel 12 into the aluminum-plastic film. Among them, the function of the aluminum-plastic film is to seal the reel 12 and the pole roll 2 to prevent the environment from affecting the pole roll 2. Based on this, when the limit block 13 includes a foam layer or a tape layer, the foam layer or the tape layer will not damage the aluminum-plastic film because of its flexibility, which is conducive to ensuring the integrity of the aluminum-plastic film.
[0089] In some embodiments, please see Figure 1 to Figure 2 The packaging box 1 further includes a reinforcing member 15. The reinforcing member 15 is connected to the cavity wall of the accommodating cavity, and the reinforcing member 15 is close to the limiting block 13. The reinforcing member 15 is used to strengthen the cavity wall of the accommodating cavity.
[0090] In this embodiment, the strength of the cavity wall connected to the reinforcing member 15 in the accommodating cavity can be improved. The cavity wall is not easily deformed or even damaged by force. Specifically, when the reel 12 abuts against the limit block 13 and the limit block 13 abuts against the cavity wall, the cavity wall is not easily deformed or damaged.
[0091] The shape of the reinforcement member 15 can be set to be various. In one setting, the reinforcement member 15 can be set to a long strip structure. In another setting, the reinforcement member 15 can be set to a rectangular plate. When the reinforcement member 15 is set to a rectangular plate, the size of the reinforcement member 15 can be larger than the size of the limit block 13 in the first direction Y or the second direction Z, so as to increase the strength of the cavity wall of the accommodating cavity being reinforced.
[0092] There are many ways to connect the reinforcement member 15 to the cavity wall of the accommodating cavity. For example, an adhesive can be provided between the reinforcement member 15 and the cavity wall of the accommodating cavity, and the adhesive can bond the reinforcement member 15 to the cavity wall of the accommodating cavity. For another example, both the reinforcement member 15 and the cavity wall of the accommodating cavity can be provided with rivet holes, and the rivets can pass through the rivet holes to connect the reinforcement member 15 to the cavity wall of the accommodating cavity.
[0093] In addition, the cavity wall connected to the reinforcement member 15 in the accommodating cavity may include a first part and a second part. The first part may be located relative to the second part near the cavity opening where the reel 12 enters, and the first part and the second part may be spliced. The end of the first part near the second part may be connected to the aforementioned stop block 13, and the end of the second part near the first part may be connected to the reinforcement member 15. In this way, when the first part and the second part are spliced, the second part will not be easily deformed due to the presence of the reinforcement member 15, which is conducive to the splicing of the first part and the second part.
[0094] In some embodiments, please see Figure 1 to Figure 2 The packaging box 1 further includes a first limiting plate 141 and a second limiting plate 142, both of which are slidably connected to the cavity wall of the accommodating cavity, and the plate surface of the first limiting plate 141 and the plate surface of the second limiting plate 142 are coplanar. The first limiting plate 141 and the second limiting plate 142 both abut against the circumferential surface of the reel 12 to limit the reel 12 in the radial direction of the reel 12.
[0095] In this embodiment, the first limiting plate 141 and the second limiting plate 142 can apply force to the circumference of the drum 12 to prevent the drum 12 from moving in the radial direction. When the drum 12 does not move in the radial direction, the pole roll 2 wound on the drum 12 does not move in the radial direction of the drum 12, the pole roll 2 does not collide with other components in the box 11, and the quality of the pole roll 2 can be guaranteed.
[0096] Among them, the plate surface of the first limiting plate 141 and the plate surface of the second limiting plate 142 can be parallel to the plane formed by the aforementioned first direction Y and the second direction Z. There can be multiple arrangements of the first limiting plate 141 and the second limiting plate 142. In some ways, the first limiting plate 141 and the second limiting plate 142 are arranged along the aforementioned first direction Y. In other ways, the first limiting plate 141 and the second limiting plate 142 are arranged in the aforementioned second direction Z. In some other embodiments, the first limiting plate 141 and the second limiting plate 142 are arranged in a direction other than the first direction Y and the second direction Z. The embodiment of the present application does not specifically limit the arrangement of the first limiting plate 141 and the second limiting plate 142.
[0097] The first limiting plate 141 and the second limiting plate 142 may be in various forms, and based on the different forms of the first limiting plate 141 and the second limiting plate 142 , the first limiting plate 141 and the second limiting plate 142 limit the reel 12 in different ways.
[0098] In some examples, the first limiting plate 141 and the second limiting plate 142 are both configured as square plates. The reel 12 can be clamped between one side of the first limiting plate 141 and one side of the second limiting plate 142. In this way, the first limiting plate 141 and the second limiting plate 142 can apply forces in two directions to the reel 12 to limit the reel 12 in two directions.
[0099] In other examples, a first arc-shaped groove adapted to the reel 12 is provided on one side of the first limiting plate 141 close to the second limiting plate 142, and a second arc-shaped groove adapted to the reel 12 is provided on one side of the second limiting plate 142 close to the first limiting plate 141. The reel 12 can be clamped in the first arc-shaped groove and the second arc-shaped groove, and the groove wall of the first arc-shaped groove and the groove wall of the second arc-shaped groove limit the reel 12. In this way, the groove wall of the first arc-shaped groove and the groove wall of the second arc-shaped groove can apply forces in multiple directions to the reel 12 to limit the reel 12 in multiple directions.
[0100] Furthermore, the first limiting plate 141 can be closer to the cavity opening of the accommodating cavity relative to the second limiting plate 142, and the first limiting plate 141 can be provided with a first support bar and a second support bar on the side facing the pole coil 2, and an escape space can be formed between the first support bar and the second support bar. The escape space is used to accommodate the stacking area formed after the aluminum-plastic film is evacuated, so as to prevent the first limiting plate 141 from excessively squeezing the stacking area, causing the pole coil 2 to be damaged by the stacking area.
[0101] In some embodiments, see Figure 6 The reel 12 includes a first limiting portion 121 and a second limiting portion 122 , and a winding area Q is defined between the first limiting portion 121 and the second limiting portion 122 , and the winding area Q is used for winding the pole roll 2 .
[0102] In this embodiment, the first limiting portion 121 and the second limiting portion 122 can cooperate with the winding device so that each layer in the pole roll 2 can be stacked in the winding area Q. In this way, after the pole roll 2 is formed, the end surface of the pole roll 2 can be relatively flat, the pole roll 2 is not easily damaged by other components, and the quality of the pole roll 2 can be guaranteed.
[0103] Specifically, the cooperation between the first limit portion 121, the second limit portion 122 and the winding device can be reflected as follows: the first limit portion 121 and the second limit portion 122 can be used as reference positions. In the process of the winding mechanism in the winding device winding the pole piece on the reel 12, the detection device in the winding device can determine whether the pole piece is located in the winding area Q by detecting whether the first limit portion 121 and the second limit portion 122 are detected.
[0104] Among them, the first limiting portion 121 and the second limiting portion 122 can be set in a variety of forms. In one form, the first limiting portion 121 and the second limiting portion 122 are both configured as limiting grooves. In another form, the first limiting portion 121 and the second limiting portion 122 are both configured as lines. In yet another form, one of the first limiting portion 121 and the second limiting portion 122 is configured as a limiting groove, and the other is configured as a line. The embodiment of the present application does not specifically limit the form of the first limiting portion 121 and the second limiting portion 122.
[0105] In addition, the winding device can be an existing device, the winding mechanism and the detection device in the winding device are all existing technologies, and the setting positions of the winding mechanism and the detection device in the winding device are also existing technologies. The embodiments of the present application will no longer provide detailed descriptions of the above content.

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.
