Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a laser cutting machine. Background Technology

[0002] Laser processing is currently the mainstream method for processing diamonds. Compared with traditional machining methods, laser processing offers higher precision, higher efficiency, and greater versatility, making it widely used in diamond cutting, micro-hole forming, micro-channel machining, and surface smoothing. However, existing cutting machine fixtures have a limited range of base designs, poor adaptability to various fixtures, and difficulty in achieving compatibility. Each fixture must be matched to its base individually, and most fixtures are fixed, preventing rotary cutting. Furthermore, the limited Z-axis lifting range of cutting machines restricts the use of certain fixtures for specific cutting processes, thus limiting cutting capabilities. Utility Model Content

[0011] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0012] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0014] like Figures 1-2As shown, a laser cutting machine includes a housing 100, within which a cutting chamber is disposed. The cutting chamber houses a liftable laser cutting head 1 and a platform 2, the platform 2 being located directly below the laser cutting head 1. An XY alignment platform 3 and a workpiece carrier 4 are disposed on the platform 2. The workpiece carrier 4 is mounted on the output end of the XY alignment platform 3. The workpiece carrier 4 includes a housing 41, a servo motor 42, a rack and pinion 43, a guide groove 44, a clamp 45, and connecting components. 46. ​​The outer casing 41 is mounted on the XY alignment platform 3. The servo motor 42 and guide groove 44 are mounted inside the outer casing 41. The rack 43 is movably disposed in the guide groove 44. The output end of the servo motor 42 meshes with the rack 43, driving the rack 43 to move within the guide groove 44. Several clamps 45 are mounted side-by-side and spaced apart on the outer casing 41 via bearings. The rear end of the clamp 45 meshes with the rack 43 via gears. The connecting piece 46 is detachably inserted into the clamp 45. Specifically, the housing 100 has a sealed cutting chamber to prevent smoke from escaping during cutting. A liftable laser cutting head 1 is installed inside the cutting chamber to meet the Z-axis lifting range requirements for cutting. The XY alignment platform 3 is installed on the stage 2. The XY alignment platform 3 can drive the outer casing 41 of the workpiece carrier 4 to move along the X and Y directions on the horizontal plane, facilitating the operator to clamp the connecting piece 46 with the workpiece attached. At the same time, it matches the position of the laser cutting head 1 to perform point cutting operations. The servo motor 42 is housed inside the housing 41, which seals and protects the servo motor 42. Under background control, the servo motor 42 precisely regulates its output power and speed. When the servo motor 42 rotates, its output gear meshes with the rack 43, which drives the rack 43 to move back along the guide groove 44. When the rack 43 moves, several clamps 45 that mesh with the rack 43 rotate on the housing 41 due to the displacement of the rack 43. This causes the connectors 46 inserted in the clamps 45 to rotate as well. In this solution, the workpiece is glued to the front end of the connector 46, eliminating the need for special clamping parts to match the size of the workpieces. This makes it more adaptable to various workpieces and improves compatibility. During cutting, the vision inspection system on the laser cutting head 1 detects the workpiece directly below it and then begins cutting according to the set parameters and preset path. The specific principle is that the high energy density of the laser and the absorption characteristics of diamond convert light energy into heat energy, generating high temperature and high pressure on the diamond surface, causing the diamond to evaporate and fracture, thus achieving efficient and precise diamond cutting. During the cutting process, the connecting piece 46 rotates to achieve rotary cutting. After the workpiece on the current connecting piece 46 is cut, the XY alignment platform 3 moves in the X and Y directions to move the workpiece on another connecting piece 46 to directly below the laser cutting head 1, repeating the operation. This allows multiple workpieces to be cut at once without opening the cutting chamber, improving work efficiency.

[0015] Specifically, the connector 46 is made of copper and has good thermal conductivity.

[0016] like Figure 2 As shown, the clamp 45 is provided with a locking bolt 451. The inner end of the locking bolt 451 abuts against the connector 46. The locking bolt 451 is used to fasten the connector 46 inserted into the clamp 45, so as to prevent the connector 46 from loosening during the rotation of the clamp 45, which would lead to a decrease in cutting accuracy.

[0017] like Figure 1 As shown, a control console 5 is provided on the housing 100. The control console 5 is designed side by side with the cutting chamber, integrating cutting and programming operations. This allows operators to directly adjust the parameter design of the laser cutting head 1 on the control console 5, making workshop operation more convenient.

[0018] like Figure 1 As shown, the cutting chamber is equipped with an observation window 101, which allows operators to easily observe the cutting status through the observation window 101.

[0019] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
