Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lithium battery processing and production, in particular to a diaphragm roller baffle. Background Art
[0002] In the structure of lithium batteries, the diaphragm is a vital component. The diaphragm of a lithium battery is located between the positive and negative electrodes. Its main function is to isolate the positive and negative electrode materials and prevent the battery from short-circuiting during charging and discharging. The diaphragm is also an ion-conductive material, which allows lithium ions to migrate between the positive and negative electrodes, but prevents electrons from passing through.
[0003] There is space above the diaphragm roller bracket, and the surface of the roller bracket is rough and dusty, and the diaphragm may be passed over the roller bracket. The diaphragm contacts the bracket, causing dust to stick to the surface, and even scratches the diaphragm, affecting the safety and performance of the battery cell. Therefore, a diaphragm roller baffle is proposed to prevent the diaphragm from passing through the top of the bracket. For example, Chinese patent announcement No. "CN220148764U" in the prior art discloses a roller adjustment device, including a bracket, an adjustment mechanism, and a roller. The roller is installed on the bracket through the adjustment mechanism, and is characterized in that the adjustment mechanism includes a fixed seat installed on the bracket, and a movable plate is provided on the fixed seat which can be raised and lowered and fixed by a fastening assembly, and the axial end of the roller is installed on the movable plate; one of the movable plate and the fastening assembly has a recessed portion, and the other has a raised portion, and the raised portion is plugged into the recessed portion. The roller adjustment device proposed in the utility model is to lift and lower the movable plate on the fixed seat, and the movable plate can be positioned after lifting by plugging the fastening component and the movable plate, which not only facilitates the height adjustment of the roller, but also plays a role in maintaining stability, preventing the roller from being horizontally unbalanced, thereby avoiding the phenomenon of sheet deviation and wrinkling.
[0004] During actual operation, there is space above the diaphragm roller bracket, and the surface of the roller bracket is rough and dusty. Because there is no baffle to block the diaphragm, the staff may pass the diaphragm over the roller bracket. The diaphragm contacts the bracket, causing dust to stick to the surface and even scratching the diaphragm, affecting the safety and performance of the battery cell. Utility Model Content
