Description

Technical Field

[0001] This utility model relates to an improved invention of a laser cutting machine, and more particularly to an improved invention of a three-dimensional scanning laser stereoscopic cutting machine. Background Technology

[0002] Current laser cutting machines often rely on original 3D design data when cutting materials such as acrylic vacuum forming. However, in practical applications, many materials are not generated through computer design and lack original 3D model data, making it difficult to directly generate cutting paths. Traditional methods require manually acquiring material data, i.e., manually collecting cutting points in the machine and then connecting them into lines. This process is time-consuming and has low accuracy, failing to meet the demands for efficient and precise cutting. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a three-dimensional scanning laser stereo cutting machine.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: This three-dimensional scanning laser cutting machine includes a body, a cutting platform, and a control system. Its features include: a laser head lifting assembly that can move laterally and longitudinally is provided above the cutting platform, along with a lateral drive mechanism and a longitudinal drive mechanism; the laser head lifting assembly includes a laser head and a lifter, with the laser head being driven to move up and down by the lifter; a gantry frame is provided on the body, and a high-definition camera is mounted on the gantry frame, corresponding to the cutting platform and extracting the cutting contour of the material; the cutting machine is also equipped with a three-dimensional scanner, which collects three-dimensional data of the material surface; the control system receives the material's cutting contour and surface three-dimensional data, and generates an actual cutting path to control the laser head to complete the cutting; the cutting platform has three or more non-collinear positioning posts, which are positioned and cooperate with the cutting material.

[0005] The positioning posts are provided in a four-dimensional array and their positions are adjustable. The corresponding cutting material has positioning holes that are matched and fitted with the positioning posts.

[0006] The lateral drive mechanism includes a lateral slide rail and a lead screw transmission structure. The corresponding laser head lifting assembly is mounted on the lateral slide rail and is driven by the lead screw transmission structure.

[0007] The longitudinal drive mechanism includes longitudinal slide rails located on both sides of the cutting platform, and the transverse drive mechanism has rollers and roller drive power sources at both ends, with the rollers matched and arranged on the longitudinal slide rails.

[0008] The beneficial effects of this utility model are that the improved three-dimensional scanning laser stereo cutting machine acquires the material cutting contour and surface three-dimensional data through a high-definition camera and a three-dimensional scanner, respectively, solving the cutting problem when there is no original design data; after receiving the contour and three-dimensional data, the control system can quickly calculate and generate the actual cutting path, replacing the traditional time-consuming manual copying method.

[0013] The accompanying drawings illustrate the structure of this utility model, and further details will be described below with reference to the drawings. In this embodiment, see the attached drawings. Figure 1-3 This 3D scanning laser cutting machine includes a body 1, a cutting platform 2, and a control system. A laser head lifting assembly 3, capable of horizontal and vertical movement, is mounted on top of the cutting platform 2, and is equipped with a horizontal drive mechanism 4 and a vertical drive mechanism 5. The laser head lifting assembly 3 includes a laser head and a lifter, with the laser head being driven to rise and fall by the lifter. A gantry 6 is mounted on the body 1, and a high-definition camera 7 is mounted on the gantry 6. The high-definition camera 7 corresponds to the cutting platform 2 and extracts the cutting contour of the material. The cutting machine is also equipped with a 3D scanner, which collects 3D data of the material surface. Preferably, the 3D scanner is handheld and can be shared by multiple cutting machines. The control system receives the material's cutting contour and surface 3D data, and generates an actual cutting path to control the laser head to complete the cutting. The cutting platform 2 has three or more non-collinear positioning posts 8, which are positioned and cooperate with the cutting material. These three positioning posts can also serve as reference points for the coordinate system of the 3D scanner and the high-definition camera.

[0014] As a further improved implementation, the positioning posts are provided in a four-dimensional array, and their positions are adjustable. The corresponding cutting material is provided with positioning holes, which are matched and sleeved with the positioning posts.

[0015] As a further improved specific implementation, the lateral drive mechanism 4 includes a lateral slide rail and a lead screw transmission structure. The corresponding laser head lifting assembly 3 is set on the lateral slide rail and driven by the lead screw transmission structure to realize the lateral movement of the laser head.

[0016] As a further improved specific implementation, the longitudinal drive mechanism 5 includes longitudinal slide rails disposed on both sides of the cutting platform 2, and the transverse drive mechanism 4 is provided with rollers and roller drive power sources at both ends. The rollers are matched and disposed on the longitudinal slide rails to realize the longitudinal movement of the laser head.

[0017] In operation, the cutting material is placed on the cutting platform 2 and positioned by the positioning posts 8. The three positioning posts serve as reference points, and the three points determine a plane. First, a 3D scanner is used to collect the 3D data of the material surface. Then, a cutting template with high color contrast is placed on the material, and a high-definition camera 7 takes pictures in the vertical direction to extract the cutting trace curve of the material plane. Then, based on the XY coordinates of the plane trace, the control system calculates the corresponding Z coordinate in the collected 3D model file to calculate the 3D coordinate data of the cutting trace. This data is then reverse-calibrated by the camera to obtain the final cutting trajectory data. Finally, the control system controls the laser head to perform lateral, longitudinal, and lifting actions to complete the cutting.

[0018] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
