The invention discloses a laser cleaning method suitable for a top cover sheet of a power battery. The laser cleaning method is used for solving the technical problem that the removal efficiency is low due to the fact that the burr is mainly removed manually in the blanking process of hardware on the top cover sheet of an existing power battery. The laser cleaning method comprises the steps: placing the top cover sheet in a carrier, controlling an X-axis drive module and a Y-axis drive module to transfer the top cover sheet on the carrier into a sensing area of an CCD, and detecting the accurate position of a to-be-cleaned area on the top cover sheet by using the CCD; controlling the X-axis drive module and the Y-axis drive module to adjust the position of the top cover sheet according tothe accurate position of the to-be-cleaned area on the top cover sheet detected by the CCD; controlling a height sensor to detect the height of the to-be-cleaned area of the top cover sheet, and controlling a Z-axis drive module to adjust the position of a laser cleaning head in the Z-axis direction according to the height of the to-be-cleaned area on the top cover sheet; and starting the laser cleaning head to clean the to-be-cleaned area.
Description
technical field [0001] The invention relates to the technical field of power batteries, in particular to a laser cleaning method suitable for the top cover sheet of the power battery. Background technique [0002] The top cover sheet is an important part of the polymer lithium-ion battery, and its quality directly affects the quality of the power lithium battery. In the existing technology, metal punching is mainly used for mass production of top cover sheets, which inevitably produces metal burrs, the main metal burrs include metal wires, burrs, etc. [0003] When there are metal wires or burrs on the top cover of the power battery, especially at the junction of the top cover and the pole, it will cause a short circuit failure of the power battery Cell, and there is a risk of explosion, which reduces the safety of the power lithium battery. At the same time, it affects the yield rate of power lithium battery production and increases the scrap rate, thereby increasing the p...
