[0022] In this embodiment, the laser head 6 can move in three axes on the X-axis, Y-axis and Z-axis. Specifically, a Y-axis screw assembly 12 is provided on the processing table 11. The Y-axis screw assembly 12 includes a motor, a screw and a nut seat. The screw assembly belongs to the prior art and will not be described in detail in this embodiment. The crossbeam 4 is connected to the nut seat of the Y-axis screw assembly 12 through a Y-axis slide 121. The two anti-reflective mirror seats 5 are arranged on the Y-axis slide 121. The motor drives the screw to rotate, and the rotation of the screw is converted into the linear motion of the nut seat. The nut seat can drive the Y-axis slide 121 to move horizontally in the Y-axis direction. At this time, the crossbeam 4 and the two anti-reflective mirror seats 5 can both move horizontally along the Y-axis direction. The crossbeam 4 is provided with an X-axis driving rail 13, and an X-axis slide 131 is connected to the X-axis driving rail 13, and a Z-axis lifting motor 14 is connected to the X-axis slide 131. The X-axis driving rail 13 can directly drive the X-axis slide 131 to move horizontally in the X-axis direction, and the Z-axis lifting motor 14 moves with the movement of the X-axis slide 131. At the same time, in order to ensure the accuracy of the operation, a CCD positioning camera 8 is also connected to the X-axis slide 131, and the CCD positioning camera 8 can locate the product position to ensure that the laser head 6 can be accurately processed at the processing position.

The telescopic member includes a plurality of dust-proof cylinders 15 that are mutually engaged, such as Figure 3 As shown, the inner diameters of the dustproof tubes 15 gradually decrease from top to bottom, that is, when the laser head 6 is lifted and lowered driven by the Z-axis lifting motor 14, the three-reflecting mirror seat can always be aligned with the laser head 6, so that the laser beam can accurately enter the laser head 6.
[0024] Specifically, the first reflector seat group 3, the second reflector seat group 5 and the third reflector seat group 7 all have a reflection angle of 45°. The laser beam emitted horizontally by the laser tube 21 passes through the first reflector seat group 3 and enters the second reflector seat group 5 with a horizontal refraction of 90°. The laser beam passes through the second reflector seat group 5 and enters the third reflector seat with a vertical refraction of 90°. The laser beam passes through the third reflector seat group 7 and enters the laser head 6 with a vertical refraction of 90°. Since the laser cabinet 2 and the first reflector seat group 3 are fixed on the processing table 11, that is, the laser tube 21 can stably emit a laser beam, the laser beam passes through the second reflector seat group 5 from the first reflector seat group 3, and the path of the laser beam is changed by the movement of the second reflector seat group 5, so that the laser beam can enter the third reflector seat, ensuring that the laser beam can continuously enter the laser head 6 for laser cutting operation. Preferably, the processing table 11 is a marble component made of granite with high rigidity, which greatly reduces the influence of external factors on the laser tube 21 and ensures the stability of the laser tube 21, that is, can ensure the stable emission of the laser beam.
[0025] Furthermore, two laser tubes 21 are provided in the laser cabinet 2, and each laser tube 21 is matched with one anti-reflective mirror seat group 3 and one anti-reflective mirror seat group 5. One anti-reflective mirror seat group 3 and one anti-reflective mirror seat group 5 corresponding to one laser tube 21 are both arranged on one side of the processing table 11, and one anti-reflective mirror seat group 3 and one anti-reflective mirror seat group 5 corresponding to another laser tube 21 are both arranged on the other side of the processing table 11, and the three anti-reflective mirror seat group 7 can be rotatably matched with the two anti-reflective mirror seat groups 5. When one laser tube 21 is damaged and does not work, the other laser tube 21 can be quickly started, and the three anti-reflective mirror seat group 7 can be rotated to align with the corresponding two anti-reflective mirror seat group 5, which greatly shortens the equipment downtime and greatly improves the working efficiency.
[0026] Furthermore, the processing table 11 is provided with a notch 111, and a plurality of aluminum blades 112 are connected to the notch 111, and a blanking gap is formed between every two aluminum blades 112, and a blanking funnel 113 is provided below the notch 111. Figure 4 As shown, the product is placed on a number of aluminum blades 112 for processing, and the processed waste can directly enter the blanking funnel 113 through the blanking gap. A waste drawer can be provided at the outlet of the blanking funnel 113 in the machine 1 corresponding to the outlet of the blanking funnel 113, and the operator can directly handle the processing waste by opening the waste drawer.
[0027] In order to ensure the safety of laser cutting, the work surface is connected to a protective cover 16, and an openable door panel 17 is connected to the protective cover 16. Before processing, the door panel 17 is opened to place the product to be processed. After processing, the door panel 17 can be opened to take away the processed product.
