Arc surface adjustable feeding method and equipment for laser machine

Abstract

The invention discloses an arc-surface-adjustable material conveying method for a laser machine. The arc-shaped adjustable material conveying method comprises the following steps that the upper surface of a die-cutting platform for bearing a material to be die-cut is made into an arc surface; the material to be die-cut is conveyed to the arc surface of the die-cutting platform through a material conveying device; in the laser die-cutting process of the material to be die-cut, a galvanometer projects focused laser beams onto the material to be die-cut located on the arc surface of the die-cutting platform according to a scanning path; and the radius of the arc surface of the die-cutting platform is adjusted according to the die-cutting size of the material to be die-cut so that the focus trajectory formed by the laser beams can always fall on the material to be die-cut. The invention further provides equipment suitable for the method. The equipment is simple in structure and convenient to use, the radius of the arc surface of the die-cutting platform can be adjusted according to the die-cutting size of the material to be die-cut, and it can be guaranteed that the focus of the laser beams always falls on the material to be die-cut, so that the die-cutting quality is improved, and the energy loss of the laser beams is reduced.

Description

Technical field [0001] The invention relates to the field of machinery, in particular to a curved surface adjustable feeding method and equipment for laser machines. Background technique [0002] In the prior art, a laser machine is often used to perform die-cutting processing on die-cut materials, and the laser machine die-cutting processing methods include scanning before the lens and scanning after the lens. Among them, the structure of the post-lens scanning system used in the prior art is as figure 1 As shown, the laser light emitted by the laser transmitter is focused by the condenser lens 2 and then projected onto the galvanometer 10, and then the galvanometer 10 completes the die-cutting process on the material to be die-cut according to the scanning path. [0003] When the galvanometer 10 rotates according to the scanning path to complete the die-cutting process, the focal point of the laser beam 9 projected by the galvanometer forms an arc-shaped focal track (such as figu...

AI Technical Summary

Problems solved by technology

After the focus diverges, a larger spot is formed at point B of the material to be die-cut, resulting in a decrease in laser energy density or a decrease in die-cutting accuracy, which seriously affects the quality of laser die-cutting
