[0002] The multi-axis positioning device for laser marking is a key piece of equipment in the laser marking process. It is equipped with X, Y, and Z axis motion platforms, and each axis works together to achieve precise displacement and positioning. High-precision guide rails, lead screws, and high-performance bearings ensure the accuracy of marking.

[0003] Existing multi-axis positioning devices for laser marking have certain shortcomings in use. To ensure the accuracy of marking, it is often necessary to place the parts in a specific position. If the parts are placed manually, not only is the accuracy poor, but the efficiency is also low. Therefore, it is necessary to design a new multi-axis positioning device for laser marking with positioning function to solve this problem. Utility Model Content

[0006] Base; conveyor belt mounted on the surface of the base;

[0007] The positioning mechanism includes hydraulic rods symmetrically distributed on both sides of the top of the base, a baffle fixedly connected between the hydraulic rods, two side plates slidably disposed on the surface of the baffle, a guide plate fixed to the tail end of the side plate, a pressure sensor disposed on one side of the baffle, a scale line disposed on the top of the baffle, and a ball bearing disposed on one side of the guide plate.

[0008] Preferably, the positioning mechanism includes a rectangular sleeve, which slides on the surface of the baffle, and the side plate is fixed to one side of the rectangular sleeve.

[0009] Preferably, the positioning mechanism further includes a threaded fastening rod, which is threadedly connected to the top of the rectangular sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When placing the parts, the position of the side plates can be adjusted in advance. Then, the parts are placed on the surface of the conveyor belt. This process only needs to ensure that the position of the parts is roughly accurate. As the conveyor belt transports the parts, the parts will be gradually corrected by the guide plates until the parts fit and are embedded between the side plates. At this time, the conveyor belt stops moving. With the cooperation of the above structure, the parts can be automatically and accurately positioned, which not only ensures the accuracy of marking, but also improves efficiency.
