Technical Field

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

[0002] The laser marking machine uses a laser beam to mark the surface of various materials permanently. The effect of the marking machine is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks and texts.

[0003] Some equipment on the market is generally provided with a clamping rod and a clamping groove, which is conducive to fixing the pressure block through the clamping rod to prevent the pressure block from moving due to excessive contact friction with the marking table. The provision of a screw rod is conducive to moving the pressure plate to a position corresponding to the workpiece. The provision of a pressure block is conducive to fixing the workpiece and effectively preventing lighter workpieces from moving on the surface of the marking table due to external influences, thereby preventing marking errors from damaging the workpiece and improving the workpiece marking efficiency.

[0004] However, in actual use of the above equipment, when the product is pushed during transportation, the interface between the product and the clamping structure placed under the marking machine will deviate, which will cause the product to get stuck in the transmission clamping device, making it impossible for the marking machine to mark the product. In view of this, we propose a laser marking machine that can automatically position the workpiece. Utility Model Content
