Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to an automatically replaced cleaning bottom plate structure. Background Art

[0002] Lithium-ion batteries have attracted widespread attention due to their advantages such as high energy density and environmental friendliness. They have been widely used in mobile and portable electronic devices such as mobile phones and laptops. In particular, the rapid popularization and development of smartphones and tablets have greatly promoted the replacement of lithium-ion batteries.

[0003] During the production of lithium batteries, lasers are required to perform local cleaning of the paste-coated areas of the cold-pressed pole pieces at the required intervals to clean out the corresponding empty foil areas, while the cleaning base plate ensures stable cleaning of the pole pieces. Due to the penetrating power of the laser, there is a phenomenon of laser penetration and damage to the cleaning base plate when cleaning the pole pieces. The flatness of the cleaning base plate is one of the main factors affecting the cleaning accuracy of the pole pieces. A decrease in the flatness of the cleaning base plate will lead to a decrease in cleaning accuracy and may even penetrate the pole pieces. Therefore, the cleaning base plate needs to be regularly maintained and replaced. However, due to the special location of the cleaning base plate, when replacing the cleaning base plate, the pole piece needs to be cut off and then disassembled and replaced. The overall time consumption is 1-2 hours, which affects production efficiency. Utility Model Content
