Description

TECHNICAL FIELD

[0001] The present application relates to the field of composite current collector processing, in particular to a blind hole continuous processing device on a composite current collector. BACKGROUND

[0002] The composite current collector is a functional material based on the design of a multi-layer film composite structure. By laminating materials with different physical and chemical properties, an integrated carrier with conductivity, mechanical strength and interface stability is formed. Its core function is to efficiently transport charges and carry electrode active materials, and it is widely used in high-end fields such as new energy batteries and flexible electronic devices. Due to the differences in the expansion coefficient, stress distribution and interface bonding characteristics of the materials in the composite structure, such materials need to consider the synergistic effect of multiple layers during preparation to achieve the optimization of overall performance. The surface flatness and structural stability have a decisive influence on the subsequent processing precision, and are the key basic materials to ensure the electrochemical performance and service life of the terminal product.

[0003] During the blind hole processing of the composite current collector, the material surface is prone to local warping, wrinkling and other unevenness due to mechanical traction. Such deformation can cause the laser focusing position to deviate from the preset processing point, resulting in blind hole position deviation, uneven aperture and other problems. Especially in the continuous production scene, the dynamically transported composite current collector is affected by tension fluctuations and material rebound characteristics, and the surface undulation state is random, which increases the difficulty of positioning precision control.
