Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing, in particular to a novel grinding and polishing device. Background Art

[0002] In the production process of lithium batteries, the sealing effect is an important part of the packaging process. In the daily production process, it is an indispensable means to check the sealing effect and sol through metallography.

[0003] If you want to do metallography, you need a grinder and polisher. However, the existing grinders and polishers are generally large in size, and personnel are required to manually press the metallographic structure during the grinding and polishing process. Firstly, the surrounding environment is easily polluted by splashing sewage. Secondly, if it is not compacted, the metallographic structure is easy to fly out, which poses a greater safety risk to the operator. For this reason, we propose a new type of grinding and polishing device. Utility Model Content
