Abstract

The invention relates to a laser marking machine, which comprises a laser (13), an embedded industrial control system (12) and a galvanometer system (4), wherein the embedded industrial control system (12) and the laser (13) form a loop with a power supply through conducting wires, and the galvanometer system (4) is arranged on a marking working head (23). The laser marking machine is characterized in that the laser (13) is an optical fiber laser, and the laser (13) and the embedded industrial control system (12) can be positioned in a movable moving box (1); the laser (13) is connected with a focusing device through an optical fiber (14); and the focusing device is adapted together with the galvanometer system (4). Adopting a semiconductor pump fiber laser as a light source, the laser marking machine has the advantages of simple structure, small volume, high conversion efficiency, good laser beam quality, long service life and no maintenance so that a bulky cooling device is not needed in the marking process for the convenience of movable marking. Besides, the movable optical fiber laser marking machine not only requires a simple environment without constant temperature, constant humidity and a water-cooling facility, but also is applicable to a severe environment, thereby having the advantages of least material consumption, international common software, easy learning and understanding, small volume, light weight, small occupied area, and long service life.

Description

technical field

[0001] The invention relates to a marker, in particular to a laser marker. Background technique

[0002] There is an existing Chinese utility model patent No. 02265752.5 titled "Laser Marking Device with Translating Adjustable Light Guide System", which proposes a structure, which is characterized in that there is a translation between the laser light source and the workpiece to be marked. Adjustable light guide system, the system includes two total reflection mirrors, a focusing scanning system composed of focusing mirrors, X and Y scanning mirrors, and a translation device is installed between the two total reflection mirrors and between the total reflection mirror and the focusing scanning system. tuning device. This can keep the laser light source and the workpiece stationary, and adjust the distance between the two total reflection mirrors and the distance between the total reflection mirror and the focusing scanning system through the translation adjus...
