[0003] Existing gemstone laser cutting processes involve fixing a fixture below the laser emitter and then placing the gemstone slice on the fixture for laser cutting. If the fixture becomes loose or wears out, the precision and stability of the laser cutting will decrease significantly. Furthermore, the number of gemstones that can be placed on the fixture at one time is limited, resulting in low processing efficiency. Summary of the Invention

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figures 1-3 As shown, this utility model provides a technical solution: a gemstone laser cutting machine with vision edge finding, including a base 1, a stabilizing platform 2, a pair of X-axis modules 3, Y-axis modules 4, Z-axis modules 5, a laser cutting head 6, a vacuum adsorption platform 7, an upper cover 8, and a vision camera 9. The stabilizing platform 2 is installed on the top of the base 1 and is made of a single piece of marble, serving as the base of the entire cutting mechanism to improve stability and accuracy. The pair of X-axis modules 3 are installed on both sides of the top of the stabilizing platform 2, and the Y-axis modules 4 are installed on the X-axis modules 3. The X-axis modules 3 and Y-axis modules 4 form a gantry-type moving module, thereby forming a stable support and moving structure. Z-axis module 5 is mounted on Y-axis module 4, laser cutting head 6 is mounted on Z-axis module 5, vacuum adsorption platform 7 is mounted on stabilizing platform 2 and located between a pair of X-axis modules 3, upper cover 8 is mounted on base 1, vision camera 9 is mounted on the top of the inner cavity of upper cover 8 and faces vacuum adsorption platform 7, vision camera 9, XYZ moving module and laser cutting head are all electrically connected to control host; In use, several thin-plate-shaped gemstones are placed on the vacuum adsorption platform 7 until the entire platform is covered. The vacuum adsorption platform 7 is connected to an external negative pressure source. The vacuum adsorption platform 7 has a mesh-like distribution of attraction holes, which attract and fix several gemstones. The X, Y, and Z axis modules provide a three-axis movement mechanism to drive the laser head to move. Then, the vision camera 9 captures a distribution map of the gemstone slices. Based on the set cutting requirements, the host computer calculates the cutting path and drives the laser cutting head to perform the cutting operation. After the cutting is completed, the gemstone slices are picked up.

[0015] Specifically, a material feeding trough 21 is provided in the middle of the stabilizing table 2, and a positioning plate 22 is provided on the stabilizing table 2. The positioning plate 22 is located on the top of the material feeding trough 21. The vacuum adsorption platform 7 is installed on the positioning plate 22. A receiving drawer 11 is provided at the bottom of the machine base 1. The waste generated after laser cutting can be collected on one side of the vacuum adsorption platform 7 and then fall from the material feeding trough 21 into the receiving drawer 11 for collection.

[0016] The upper cover 8 encloses the entire laser processing space to prevent dust from spreading. An upper sliding door 81 is provided at the front end of the upper cover 8 for loading and unloading materials. Observation windows are distributed on the other three sides of the upper cover 8.

[0017] Dust covers are provided on the X-axis module 3 and Y-axis module 4 to prevent dust generated during cutting from entering the module and affecting its operation.
