[0023] A second horizontal moving device 5 is provided above the processing platform 2, and the moving direction of the second horizontal moving device 5 is perpendicular to the moving direction of the first horizontal moving device 3. The second horizontal moving device 5 is connected to a vertical moving device 6, and the vertical moving device 6 is connected to a second rotating device 7. A laser head 8 is provided on the second rotating device 7. The laser head 8 is provided above the stage, and the laser head 8 is used to emit a laser beam to cut or mark the product on the stage. In this embodiment, since the moving direction of the second horizontal moving device 5 is perpendicular to the moving direction of the first horizontal moving device 3, under the premise that the first horizontal moving device 3 moves along the Y-axis direction, the second horizontal moving device 5 preferably moves horizontally along the X-axis direction, and the second horizontal moving device 5 can be specifically provided above the processing platform 2 through a bracket, and the vertical moving device 6 can specifically move along the Z-axis direction. Specifically, the second horizontal moving device 5 includes an X-axis driving rail 51, on which a second slide plate 52 is slidably connected, and the vertical moving device 6 includes a Z-axis driving rail 61 provided on the second slide plate 52, on which a third slide plate 62 is slidably connected, and the second rotating device 7 is provided on the third slide plate 62. The second slide plate 52 moves along the X-axis direction under the drive of the X-axis driving rail 51, and at this time, the second slide plate 52 simultaneously drives the entire vertical moving device 6 and the second rotating device 7 to move along the X-axis direction, and at the same time, the third slide plate 62 moves vertically along the Z-axis direction under the drive of the Z-axis driving rail 61, and the second rotating device 7 can move with the movement of the third slide plate 62. The second rotating device 7 specifically includes a B-axis rotating motor 71 disposed on the third slide plate 62. The output shaft of the B-axis rotating motor 71 rotates with the Y-axis as the rotating axis. The laser head 8 is disposed on the B-axis rotating motor 71 through a second adapter 72. When the B-axis rotating motor 71 is started, it can directly drive the second adapter 72 to rotate. The laser head 8 can smoothly rotate with the Y-axis as the rotating axis under the drive of the second adapter 72. The laser head 8 can be driven to rotate by the B-axis rotating motor 71, which can well adapt to various cutting or marking requirements, making product processing more flexible. The laser head 8 is specifically connected to a laser 81, such as Figure 5As shown, a reflector device 82 is provided between the laser 81 and the laser head 8. The laser 81 is used to emit a laser beam, and the laser beam enters the laser head 8 through the reflector device 82, and finally the laser head 8 emits a laser beam to complete the processing of the product. In summary, first, the second slide 52 drives the Z-axis drive slide 61, the third slide 62, the B-axis rotary motor 71 and the laser head 8 to move along the X-axis direction under the drive of the X-axis drive slide 51, and then the third slide 62 drives the B-axis rotary motor 71 and the laser head 8 to move up and down along the Z-axis direction under the drive of the Z-axis drive slide 61 to adjust the distance between the laser head 8 and the stage, and then the B-axis rotary motor 71 directly drives the laser head 8 to rotate with the Y-axis as the rotation axis, so that the laser head 8 can adjust the position in the three-axis directions of the X-axis, Z-axis and B-axis directions, and cooperate with the movement of the stage in the two-axis directions, that is, the five-axis adjustment can be achieved for the processing of the product, meeting the cutting and marking requirements of multi-dimensional special-shaped materials, and greatly improving the application of laser cutting and marking. Preferably, the frame 1, the processed product platform and the bracket are preferably made of marble material, which greatly reduces the impact of vibration on the laser and has better stability.
[0024] Furthermore, in order to improve the processing accuracy, a positioning device 9 is also provided. The positioning device 9 is used to detect the position information of the product on the stage. The positioning device 9 is preferably a CCD visual camera. The camera part of the CCD visual camera faces the stage. The position of the product on the stage is photographed and located by the CCD visual camera, and the position information of the product is transmitted to the back-end control system. The back-end control system synchronously drives the coordinated movement between the stage and the laser head 8 according to the processing requirements, so that the laser beam emitted by the laser head 8 can accurately locate the processing position of the product, successfully complete the cutting or marking requirements, and improve the processing accuracy. Preferably, the positioning device 9 is arranged on the third slide plate 62, so that the positioning device 9 and the laser head 8 can realize synchronous vertical movement under the drive of the third slide plate 62 and the Z-axis driving slide rail 61. On the one hand, the distance between the positioning device 9 and the product can be adjusted, so that the positioning device 9 can adjust its own shooting range according to the product size to ensure that the entire structure of the product can be photographed in place; on the other hand, the laser head 8 and the positioning device 9 adopt the same vertical driving device, which makes the structure of the laser cutting and marking machine more compact and reduces the production cost.
[0025] In addition, the laser cutting and marking machine can be equipped with auxiliary processing devices such as accordion covers, dust extraction devices, and air blowing devices. In this embodiment, accordion covers are provided on both sides of the first slide 32, the second slide 52, and the third slide 62. Each of the accordion covers respectively wraps the X-axis drive rail 51, the Y-axis drive rail 31, and the Z-axis drive rail 61 to prevent dust from entering, thereby ensuring the smooth movement of the first slide 32, the second slide 52, and the third slide 62 and ensuring the practical life. A dust extraction device is provided between the laser head 8 and the stage. The dust extraction device can be specifically composed of a dust extraction port, a blower, and a dust extraction pipe, which is used to extract the smoke and dust generated during the cutting or marking process. The laser head 8 is also provided with an air blowing device, which blows the cut product during the cutting process to blow away the melted material and prevent some easily flammable materials from catching fire during the cutting process. While greatly improving the processing accuracy, it can also improve the safety factor during product cutting or marking.
