Embodiment Construction

[0036] In order to facilitate the understanding of the present invention, the laser marking machine and the marking method will be described more fully below with reference to the relevant drawings. The preferred embodiment of the laser marking machine and marking method is given in the accompanying drawings. However, the laser marking machine and the 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 machine and marking method more thorough and comprehensive.

[0037] 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 elements may also be present. ...

Abstract

The invention relates to a laser marking machine and a marking method. The marking method is used for marking products. The marking method comprises the steps of placing a product on a rotating workbench, and making the product rotate along with the rotating workbench; dividing the marking area of the product into more than one marking unit in the tangential direction and the radial direction of the rotating workbench; acquiring the angular displacement data of the rotating workbench; measuring the distance between the laser mechanism of the laser marking machine and the multiple test points of the marking units to obtain multiple distance data; obtaining the actual marking depths of the marking units according to the multiple distance data; comparing the actual marking depths and the theoretical marking depths of the marking units to obtain the compensation values of the marking depths of the marking units; adjusting the distances between the marking mechanism and the marking units according to the compensation values; and controlling the laser mechanism to mark the marking units. According to the marking method, the marking quality of the marking units is improved, and therefore,the reliability of marking of the laser marking machine on the marking area of a product 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 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 PVC pipes...
