Description

Technical Field

[0001] The utility model relates to the technical field of laser marking machines, in particular to an automatic positioning marking component and a laser marking machine. Background Art

[0002] Laser marking machine is a device that uses laser beam to mark permanently on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "carve" traces through the chemical and physical changes of the surface material caused by light energy, or to burn part of the material through light energy to show the required etching pattern, text, etc. The basic principle of the existing automatic positioning marking machine is: the sensor identifies the position of the workpiece on the conveyor belt, and the computer controls the laser beam to act on the surface of mechanical parts, electronic components, instruments and meters that need to be marked according to a predetermined trajectory, so that the surface material is instantly vaporized or chemically changed to change color, and text, patterns, etc. with a certain depth or color are etched, thereby leaving a permanent mark on the surface of the object.

[0003] In actual use, the laser marking machine relies on the set sensor to identify the placement of the workpiece on the conveyor belt. Although it can automatically locate the workpiece and mark it, it cannot identify stacked workpieces. Therefore, during the loading process, it is necessary to manually load the workpieces one by one to control the spacing between the workpieces and avoid stacking the workpieces together, which increases the labor burden of the workers and causes a waste of human resources.
