Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery separator winding, and particularly relates to a winding device for lithium battery separators. Background Art

[0002] In a lithium battery, the separator is a crucial part. It needs to ensure the free passage of lithium ions to form a circuit, and at the same time prevent the direct contact between the positive and negative electrodes, that is, it plays an insulating role to avoid battery short - circuit. After the lithium battery separator is manufactured, it is usually necessary to wind the lithium battery separator around a core cylinder for easy storage or transportation. The core cylinder is a hollow tube. During winding, the core cylinder is sleeved on a rotating roller, and the roller drives the core cylinder to rotate. During the rotation of the core cylinder, the winding of the lithium battery separator is realized.

[0003] However, due to the characteristics of light texture and low strength of the lithium battery separator, wrinkles are likely to occur during the winding process. These wrinkles have a great impact on the lithium battery separator and seriously affect the quality of the lithium battery separator in later use. Therefore, we have proposed a winding device for lithium battery separators. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a winding device for lithium battery separators. By setting a core cylinder, specifically, first place a suitable core cylinder on the outer surfaces of two clamping plates, then start the third motor, drive the two clamping plates to approach the inner wall of the core cylinder through a bidirectional threaded rod, and then clamp the core cylinder. Then adjust the slider to move downward, so that the third rotating rod presses down on the separator sheet, making the separator sheet in a compact state, and being smooth when collecting the separator sheet, thereby being able to assemble and wind the separator on different core cylinders, thus increasing the use function of the device and enhancing the assembly ability of the device, and solving the problem that in the existing technology, the winding of the lithium battery separator is realized, but due to the characteristics of light texture and low strength of the lithium battery separator, wrinkles are likely to occur during the winding process, and these wrinkles have a great impact on the lithium battery separator and seriously affect the quality of the lithium battery separator in later use.

[0005] To solve the above - mentioned technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model relates to a winding device for a lithium battery separator, which comprises a support table. Four corners of the bottom of the support table are fixedly connected with support frames. The top of the support table is fixedly connected with a support plate. The back of the support plate is fixedly connected with a tripod one through screws. The top of the tripod one is fixedly connected with a motor one.

Then, the third motor 34 is started, and the two clamping plates 33 are driven by the bidirectional threaded rod 32 to approach each other towards the inner wall of the core cylinder 31, and then the core cylinder 31 is clamped. After that, the original diaphragm is sleeved on the outer surface of the rotating shaft 21. Then, a threaded ring 22 is installed at one end of the front of the rotating shaft 21.
