Description

Technical Field

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

[0002] Laser marking machines use laser beams to mark permanent marks on the surfaces of various materials. They are mainly used in some occasions that require finer and higher precision. The effect of marking is to expose the deeper materials through the evaporation of the surface materials, or to "carve" traces through the chemical and physical changes of the surface materials caused by light energy, or to burn part of the materials through light energy to show the patterns and texts to be etched. There are many kinds of laser marking machines currently available on the market, but there are still some disadvantages;

[0003] Existing laser marking machines mark products by setting and adjusting the height of the laser transmitter, but general devices require manual loading of products one by one, which will reduce the efficiency of product marking. At the same time, the front and back positions of the products will be different when loading, which will cause inaccurate marking positions during subsequent marking. In addition, general product marking can only achieve marking on one side, and there are limitations in device marking. For example, a Chinese utility model patent with authorization announcement number CN213053272U discloses a laser marking machine, including a frame, characterized in that the frame is provided with a workbench for placing products to be marked, a fixed frame is provided on the frame at the rear side of the workbench, a laser transmitter is provided at the upper end of the fixed frame, the transmitter head of the laser transmitter is located above the workbench, a fixed box is provided at the lower end of the fixed frame, and an adjustment mechanism for adjusting the lifting of the laser transmitter is provided at the upper end of the fixed box. An operating table and a control button are also provided on the fixed frame, and the control button is located on the outer side wall of the fixed box and close to the operating table. By adopting the above technical solution, the utility model provides a laser marking machine, which has a reasonable structure and layout, is easy to operate, and reduces the occupied area. However, this device marks the product by setting and adjusting the height of the laser transmitter, but the general device needs to manually load the product piece by piece, which will reduce the efficiency of product marking. At the same time, the front and back positions of the product will be different when loading, which will cause the position of the mark to be inaccurate during subsequent marking. In addition, the general product marking can only realize the marking of one surface, and the device marking has limitations and other problems. Therefore, we propose a laser marking machine to solve the above problems. Utility Model Content
