Description

Technical Field

[0001] This utility model belongs to the technical field of diaphragm edge-gathering devices, specifically relating to a lithium battery diaphragm edge-gathering device. Background Technology

[0002] The main function of lithium battery separator is to separate the positive and negative electrodes of the battery to prevent the two electrodes from contacting and short-circuiting. In addition, it also has the function of allowing electrolyte ions to pass through. During the processing and production of lithium battery separators, the waste edges of the separator need to be treated. This is usually done by using an edge-receiving device. The existing edge-receiving device is the equipment used to collect the waste edges during the processing and production of lithium battery separators.

[0003] According to the edge-gathering device for a lithium battery separator production line disclosed in the authorized patent application No. 202020453947.9, the existing edge-gathering device directly supports the internal guidance process of the guide frame when the waste edge is wound up during the processing and production of lithium battery separators. Therefore, it is not convenient to limit the top of the guide frame, which causes the waste edge to fall off when the lateral movement and guidance are too fast. As a result, the guide cannot be formed, and the waste edge cannot be wound up evenly and flat. This affects the convenience of the edge-gathering device in limiting the guide frame and preventing it from falling off when collecting waste edges in the production of lithium battery separators. Therefore, this utility model proposes a lithium battery separator edge-gathering device. Utility Model Content

[0004] The purpose of this utility model is to provide a lithium battery separator edge-gathering device to solve the problem mentioned in the background art that when the edge-gathering device is needed in the processing and production of lithium battery separators, it directly supports the waste edge through the guide frame for internal guidance during the winding process. Therefore, it is not convenient to limit the top of the guide frame, which causes the waste edge to fall off when the lateral movement and guidance winding is too fast, thus failing to provide guidance and the waste edge cannot be wound evenly and flatly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery separator edge-gathering device, comprising an edge-gathering device body, the edge-gathering device body including a base, a drive disk mounted on one side of the base via a rotating shaft, a main motor mounted on the side of the drive disk at the end of the rotating shaft, a movable seat provided on the other side of the base, a guide frame fixed to the top of the movable seat, and the edge-gathering device body further comprising:

[0007] A rotation control mechanism, comprising fixed mounting components disposed at both ends of the drive disk on the inner side of the base, wherein the ends of the fixed mounting components are connected to the interior of the drive disk by rotation control components.

[0008] Preferably, two air shafts are fixedly mounted on the surface of the drive disk, a reciprocating screw is rotatably mounted on one side of the top of the base, an auxiliary motor is installed at the end of the reciprocating screw inside the base, and the reciprocating screw matches the internal thread structure of the moving seat. A guide rod is welded to one side of the reciprocating screw, and the guide rod passes through the interior of the moving seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a limiting and anti-detachment mechanism, the limiting block can be closed at the top of the guide frame and fixedly installed at the top of the guide frame via a connecting shaft. This makes it less likely for the air shaft to detach when guiding the waste edge during winding. At the same time, when the air shaft touches the inner side of the guide frame during winding, it contacts the anti-friction roller and the anti-friction ball to reduce friction.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5This utility model provides a technical solution: a lithium battery separator edge-gathering device, including an edge-gathering device body 100, the edge-gathering device body 100 including a base 101, a drive disk 102 is mounted on one side of the base 101 via a rotating shaft, a main motor is mounted on the side of the drive disk 102 at the end of the rotating shaft, and two air shafts 103 are fixedly mounted on the surface of the drive disk 102 to facilitate the main motor driving the drive disk 102 and the air shafts 103 to rotate for edge-gathering. A movable seat 107 is provided on the other side of the base 101, a guide frame 104 is fixed to the top of the movable seat 107, and a reciprocating screw 106 is rotatably mounted on the top of one side of the base 101. An auxiliary motor is installed at the end of rod 106 inside base 101, and the reciprocating screw 106 matches the internal thread structure of movable seat 107. A guide rod 105 is welded to one side of the reciprocating screw 106, and the guide rod 105 passes through the interior of movable seat 107. The auxiliary motor drives the reciprocating screw 106 to rotate, and the rotation of the reciprocating screw 106 drives the movable seat 107 and guide frame 104 to move, so that the guide frame 104 slides on the outer surface of the guide rod 105 when it moves, thereby driving the guide frame 104 to move back and forth and evenly wind the waste edge on the outer surface of the air expansion shaft 103, which facilitates the edge winding of the diaphragm. The edge winding device body 100 is also provided with:

[0024] The limiting and anti-falling mechanism includes a limiting component disposed at the top of the guide frame 104, a reinforcing component disposed at the end of the limiting component, and an anti-friction rolling component disposed on the inner surface of the guide frame 104.

[0025] In order to facilitate the limiting of the top end of the guide frame 104 by means of the limiting component, and to prevent it from falling off when the guide edge is rolled up too quickly, in this embodiment, preferably, the limiting component is installed on the limiting block 1043 at the top of the guide frame 104 by means of a connecting shaft, and the lower surface of the limiting block 1043 has an arc-shaped structure at the middle position, which fixes the limiting block 1043 to the top end of the guide frame 104 and prevents it from falling off when the winding is too fast.

[0026] To facilitate the fixed installation of the limiting block 1043 after closure using the reinforcement component, in this embodiment, preferably, the reinforcement component includes a limiting adjustment groove 1045 formed on one side of the top of the guide frame 104. A threaded rod 1044 is threadedly connected to the top side of the guide frame 104. The end of the threaded rod 1044 is fixed inside the limiting adjustment groove 1045 with a limiting clamp 1046, which facilitates the movement of the limiting clamp 1046 within the limiting adjustment groove 1045 by rotating the threaded rod 1044. The end of the limiting block 1043 is provided with a clamping hole 1047 that engages with the limiting clamp 1046 until the end of the limiting clamp 1046 is engaged inside the clamping hole 1047 to reinforce and limit the limiting block 1043.

[0027] In order to facilitate the guidance of the guide frame 104 internally without causing friction damage, in this embodiment, preferably, the anti-friction rolling assembly includes two anti-friction rollers 1041 rotatably connected to both sides of the guide frame 104 internally, and anti-friction balls 1042 rolling at the bottom of the guide frame 104 internally. When the waste edge is inside the guide frame 104, it can be rolled by the anti-friction rollers 1041 to contact the inner side of the guide frame 104, and when it contacts the bottom of the guide frame 104 internally, the anti-friction balls 1042 roll to reduce friction, which facilitates smooth guidance operation.

[0028] The rotation control mechanism includes fixed mounting components located at both ends of the drive disk 102 inside the base 101. The ends of the fixed mounting components are connected to the interior of the drive disk 102 with rotation control components. The rotation control mechanism can stably support the drive disk 102 and the air shaft 103 to rotate when they rotate.

[0029] In order to facilitate the fixed installation of the arc-shaped rotating block 1023 and the stable rotation adjustment through the fixed installation component, in this embodiment, preferably, the fixed installation component includes a fixing plate 1022 disposed at both ends of the drive disk 102 and located inside the base 101. The end of the fixing plate 1022 is provided with a fixing bolt 1024, and the fixing plate 1022 is fixedly connected to the surface of the base 101 by the fixing bolt 1024. The fixing plate 1022 can be fixedly installed by the fixing bolt 1024, which facilitates fixed installation and use.

[0030] In order to facilitate stable control of the rotation of the drive disk 102 and the air shaft 103 through the rotation control component, in this embodiment, preferably, the rotation control component includes an annular groove 1021 formed on the edge of the drive disk 102. Two arc-shaped rotating blocks 1023 are arranged inside the annular groove 1021, and the arc-shaped rotating blocks 1023 are fixed to the inner surface of the fixing plate 1022 by welding. When the drive disk 102 and the air shaft 103 rotate, the arc-shaped rotating blocks 1023 can be driven to rotate stably inside the annular groove 1021, which facilitates more stable rotation and winding and is less prone to shaking and instability.

[0031] The working principle and usage process of this utility model are as follows: When using this lithium battery separator edge-gathering device, the main body 100 of the edge-gathering device is first fixedly installed at the usage position. During edge-gathering, the waste edge of the separator is placed inside the guide frame 104, and the end is wrapped around the outer surface of the inflated air shaft 103. The main motor drives the drive disk 102 and the air shaft 103 to rotate to process the waste edge of the separator. During edge-gathering, the auxiliary motor drives the reciprocating screw 106 to rotate. The rotation of the reciprocating screw 106 drives the moving seat 107 and the guide frame 104 to move, so that the guide frame 104 slides on the outer surface of the guide rod 105 when it moves. Thus, the guide frame 104 drives the waste edge to move back and forth and evenly roll it on the outer surface of the air shaft 103, which facilitates the edge-gathering of the separator. When removing the waste edge after edge-gathering, the waste edge can be removed by simply scaling the air shaft 103.

[0032] Then, when the main body 100 of the edge-retracting device is in operation, the main motor drives the drive disk 102 and the air shaft 103 to rotate. When the drive disk 102 and the arc-shaped rotating block 1023 rotate, the arc-shaped rotating block 1023 rotates inside the annular groove 1021. This makes it easier to stably control the rotation of the drive disk 102 through the fixing plate 1022 when the arc-shaped rotating block 1023 rotates. Moreover, when the air shaft 103 is subjected to force during winding, it is not easy to cause deformation and instability. The winding is more stable during long-term operation, which improves the stability of the rotation control of the drive disk 102 and the air shaft 103 by the main body 100 of the edge-retracting device during the winding of the lithium battery separator.

[0033] Finally, when the edge-receiving device body 100 is processing the edge, and the waste edge is being guided and wound inside the guide frame 104, the limiting block 1043 can be closed at the top of the guide frame 104 via the connecting shaft. Rotating the threaded rod 1044 drives the limiting clamp 1046 to move inside the limiting adjustment groove 1045 until the limiting clamp 1046 is engaged inside the clamping hole 1047. This facilitates the fixed installation of the limiting block 1043 at the top of the guide frame 104, allowing the air shaft 103 to position the waste edge. When the winding process is carried out inside the guide frame 104, it is less likely to fall off. At the same time, when winding inside the guide frame 104, it contacts the anti-friction roller 1041 to roll and reduce friction when it touches the inner side of the guide frame 104. When it is at the bottom of the guide frame 104, it contacts the anti-friction ball 1042 and rolls to reduce friction. Therefore, it is convenient to limit and prevent detachment during the guiding and edge winding process and reduce friction protection, effectively winding and improving the convenience of the edge winding device body 100 in limiting and preventing detachment of the guide frame 104 during the collection of waste edges in lithium battery separator production.
