Embodiment Construction

[0035] In order to facilitate the understanding of the present invention, the laser marking device and product marking method will be described more fully below with reference to the relevant drawings. The preferred embodiments of the laser marking device and the product marking method are given in the accompanying drawings. However, the laser marking device and product marking method can be implemented in many different forms, and are not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the laser marking device and product marking method more thorough and comprehensive.

[0036] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elem...

Abstract

The invention relates to a laser marking device and a product marking method. The product marking method comprises the steps that products are placed on a linear workbench, so that the products movesalong the linear workbench; marking areas of the products are divided into a plurality of marking units in the moving direction of the linear workbench and the direction perpendicular to the moving direction; linear displacement data of the linear workbench is collected; the distances from a laser generator of the laser marking device to a plurality of testing points of the marking units are measured correspondingly, and a plurality of distance data are obtained; actual marking depths of the marking units are obtained according to the multiple distance data; the actual marking depths are compared with theoretical marking depths of the marking units, and compensation values of the marking depths of the marking units are obtained; and output power of the laser generator is adjusted accordingto the compensation values, so that the focal position of a laser beam after passing through a light path system adapts to the marking areas, reliable marking on the products by the laser beam can berealized, and the marking effect of the laser marking device is good.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a laser marking machine and a product marking method thereof. Background technique [0002] Laser marking machine is to use laser beam to make permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to carve exquisite patterns, trademarks and characters. The types of laser marking machines include: CO2 laser marking machines, semiconductor laser marking machines and fiber laser marking machines, etc. Laser marking machines are used in the marking of some products that require finer and higher precision, for example, in electronic components, integrated circuits, electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses clocks, jewelry Marking of accessories, auto parts, plastic buttons, building materials and P...
