An ultrafast laser metal engraving method

Abstract

The invention discloses an ultrafast laser metal fine carving method, comprising the following steps: step 1, placing the product to be carved at the processing position of the fine carving device; step 2, after the product to be carved reaches the processing position of the fine carving device, The product to be engraved is triggered by the sensor to press down, and the positioning of the jig mechanism ensures that the surface to be engraved is relatively horizontal to the laser engraving device of the vibrating mirror, so as to realize ultra-fast fine engraving processing; step 3, the laser beam emitted by the laser enters the vibrating mirror through the laser optical path mechanism Laser engraving device; Step 4, the vibrating mirror laser engraving device controls the laser beam to act on the surface of the product to be engraved for fine carving processing; Step 5, the dust removal mechanism blows away the smoke generated on the product surface and performs exhaustion treatment; Step 6, Fine carving After the processing is completed, the product is recycled; the consistency of automation and the efficiency of processing are guaranteed, and at the same time, it can meet the process requirements required by Jingdiao, which is helpful for fast, accurate and fine carving products, and improves the efficiency and yield of production and processing.

Description

technical field [0001] The invention relates to the technical field of power battery laser engraving, and more specifically, the invention relates to a method for ultra-fast engraving of a battery explosion-proof valve. Background technique [0002] Due to the thin thickness and small size of the power battery explosion-proof valve, and the extremely high requirements for processing width, depth and position, it is difficult to meet the requirements of design drawings by ordinary engraving methods. Ordinary Jingdiao usually scans and engraves through pulsed lasers and laser galvanometers. The laser focus spot is small, the energy density is high, the engraving deformation is small, and the heat-affected zone is narrow to effectively improve the processing accuracy; with the galvanometer scanning, X and Y two The scanning motor controls the positions of different points in time through the scanning frequency to achieve the transformation of the entire scanning pattern to achi...

AI Technical Summary

Problems solved by technology

[0003] 1. The focus spot is large and the heat-affected zone is large, resulting in large deformation of the product;

[0004] 2. The variation range of depth and width is too large, making it difficult to meet the drawing requirements;

[0005] 3. The engraving time is long, the beat is slow, and the efficiency is low; the product consistency is poor;

[0006] 4. There are welding slag, smoke, etc. on the surface of the product after engraving;

[0007] 5. Low product yield
