Laser punching device and punching method

Abstract

The invention relates to a laser punching device and a laser punching method. The laser punching device comprises a laser system, a rotating mirror system and a control system; the rotating mirror system comprises a multifaceted prism and a rotating drive part, the multifaceted prism is in a prism shape, and is provided with multiple reflecting faces used for reflecting laser beams emitted by thelaser system, the multifaceted prism is driven by the rotating drive part to rotate so as to change the incident angle of the incident reflection faces of the laser beams emitted by the laser system,the control system controls the laser system to emit the laser beams according to the rotating angle of the multifaceted prism, and the reflecting faces of the multifaceted prism are used for reflecting the laser beams to an object to be punched for punching with different angles. Due to the fact that when the multifaceted prism rotates, the corresponding reflecting faces are provided always and reflect the laser beams, when the multifaceted prism rotates at the high speed, the laser beams can be still precisely emitted to the position, required to be punched, of the object to be punched for punching, and punching efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of laser drilling, in particular to a laser drilling device and a drilling method. Background technique [0002] Work efficiency is an important parameter in various production activities. In some assembly line production systems, the operating speed of a certain production link needs to meet the minimum requirements to avoid affecting the normal operation of other production links, thereby ensuring the efficiency of the entire assembly line production system . [0003] For example, in the assembly line production system of new energy batteries, the industry standard requires that the battery anode punching and cutting must be run at a speed above 30m / s, so as to prevent other processes of the assembly line production system from being in a waiting state. [0004] At present, laser drilling is carried out by using the traditional oscillating motor of the galvanometer. The fastest running speed of the common...
