Description

Technical Field

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

[0002] Laser marking machines use laser beams to leave marks on the surface of different materials. The laser makes the surface material evaporate and the deep material flows out to make the mark permanent. Existing laser marking machines are mainly used in applications that require fineness and higher precision. At present, most laser marking machines use a fixture to fix the bottom of the laser nozzle of the laser marking machine, and then fix the material in the fixture, so that the laser emitted from the laser nozzle directly contacts the surface of the material. The structure is simple and easy to use.

[0003] For example, the utility model with application number 202221938323.1 discloses a workpiece flipping mechanism for a laser marking machine, the present application adopts a structure in which a base is connected to a support rod, a slide groove is provided inside the support rod, a sleeve passes through the slide groove and a through hole, and a bearing is sleeved on the outside of the slide groove, and the bearing is connected to the base through a telescopic frame, so as to support the sleeve, and a threaded rod threadedly connected inside the sleeve contacts with the placement frame, and both sides of the placement frame contact with the threaded rod, the threaded rod is rotated to clamp the placement frame, and after the placement frame is fixed, the annular handle is rotated, and when the annular handle is rotated, the sleeve follows the rotation, and when the sleeve rotates, the protrusion on the outside pushes the push block, and the sleeve rotates smoothly, and the threaded rod inside the sleeve follows the rotation, driving the placement frame to rotate, and when the sleeve rotates half a circle, the placement frame follows the rotation to complete the flipping, and there is no need to remove the material from the fixture, thereby ensuring the accuracy rate, and the operation is convenient and quick, reducing safety hazards.

[0004] Similar to the above application, there are still some shortcomings:

[0005] Although the workpiece flipping mechanism of this laser marking machine replaces manual flipping of the workpiece to facilitate flipping and use, its continuity is poor. The workpiece to be marked needs to be fixed on the flipping mechanism, and then it is removed and fixed to a new workpiece after marking is completed. The operation is not continuous, which reduces work efficiency.

[0006] Therefore, a workpiece flipping mechanism for a laser marking machine is designed to optimize the above problems. Utility Model Content
