[0046] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the following further details the exemplary embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0048] In a specific embodiment, the laser cutting machine provided by the present application includes a machine body 1, a cutting device 2, a cutting moving device 3, and a clamping tooling 4; the cutting device 2 includes a laser 21, a cutting head assembly 22, a focusing lens, an industrial camera 23, and a point light source 24; the laser 21 is used to emit a laser beam to provide the energy required for material cutting. The laser beam emitted by the laser 21 is transmitted into the cutting head assembly 22 to perform laser cutting on the workpiece; the bottom of the cutting head assembly 22 has a nozzle for emitting the laser and focusing the light spot at a position 2 mm below the cutting head nozzle, such as the surface of the workpiece, to achieve precise cutting. Specifically, a focusing lens is provided inside the cutting head assembly 22 to focus the laser beam below the cutting head assembly 22, focusing the laser beam into a small point to increase its energy density, thereby improving the cutting efficiency and quality; the laser is emitted from the laser 21, conducted through an optical fiber to the cutting head and fixed to the laser output head, and then the parallel laser beam is refracted into a high-energy laser focused spot by the optical focusing lens built into the cutting head assembly 22, and the focusing position is 2 mm below the cutting head nozzle. The industrial camera 23 and the point light source 24 cooperate to image the field of view inside the cutting head nozzle. The industrial camera 23 is used to capture real-time images of the processing area to help the operator monitor the cutting process and ensure accuracy. The point light source 24 provides additional illumination for the industrial camera 23 to ensure clear images can be obtained even in low-light environments. The industrial camera 23 and the point light source 24 are used as the visual reference for horizontal positioning of the workpiece by the high-energy laser focused spot. When the function is practical, a coaxial camera method is adopted to reduce mechanical errors, improve positioning accuracy, reduce the overall size of the cutting head, and facilitate the layout of other component positions.

[0049] The machine body 1 of the present application has a hollow accommodation space, and a workbench is provided in the middle of the accommodation space; a power distribution cabinet 5 is located inside the accommodation space and below the workbench; the machine body 1 has a hollow space for accommodating all components, and a workbench is provided in the middle for placing the workpiece to be processed. The power distribution cabinet 5 stores electrical control equipment to manage the operating state of the whole machine; the cutting moving device 3 realizes three-axis movement (X, Y, Z), allowing the cutting head to move freely in three-dimensional space to meet the cutting requirements of various shaped workpieces. The clamping tooling 4 is located on the workbench and is used to clamp the workpiece and drive the workpiece to perform circumferential rotational movement.

[0050] The cutting method of the laser cutting machine includes:

[0051] S11: Control the X-axis actuator 31, Y-axis actuator 32, Z-axis actuator 33, and rotation axis actuator 41 of the cutting moving device 3 to reset;

[0052] Reset process: This is the preparatory work before startup to ensure that all mechanical parts return to their initial positions (usually the safety position or reference point defined by the system). This can guarantee the accuracy and consistency of subsequent operations. The X-axis execution component 31 is responsible for moving along the X-axis direction, the Y-axis execution component 32 is responsible for moving along the Y-axis direction, the Z-axis execution component 33 is responsible for moving up and down along the Z-axis direction, mainly used to adjust the position of the laser focus, and the rotary axis execution component 41 is used to realize the rotary positioning of the workpiece.

[0053] S12: Fix the workpiece to be processed on the clamping tooling 4, move the Z-axis execution component 33 to make the workpiece plane coincide with the laser focus plane, and determine the workpiece zero point;

[0054] Fix the workpiece: Use the clamping tooling 4 to firmly fix the workpiece to be processed on the workbench to ensure that the workpiece does not move or vibrate during the cutting process.

[0055] Adjust the Z-axis: By moving the Z-axis execution component 33, accurately adjust the position of the workpiece surface to make it coincide with the plane where the laser focus is located. This step is crucial for ensuring the cutting quality. When the laser beam is accurately focused on the workpiece surface, the best cutting effect can be obtained.

[0056] Determine the workpiece zero point: Set the origin of the workpiece coordinate system (i.e., the workpiece zero point), which is very important for programming and path planning. Usually, sensors or manual methods are used to determine this point to ensure that all subsequent movements are based on this benchmark.

[0057] S13: Set the laser parameters according to the workpiece material, control the cutting movement device 3 to drive the cutting device 2 to move according to the preset cutting route, and control the laser beam of the laser device 21 to cut the workpiece.

[0058] Set the laser parameters: Different materials require different laser power, frequency, speed and other parameters. For example, thicker metal plates may require higher power and lower speed, while thin plastics may require lower power to avoid burning. Power determines the size of the laser energy, frequency affects the cutting effect in pulse mode, and speed determines the moving speed of the cutting head, which directly affects the cutting quality and efficiency. Preset cutting route: The cutting path generated according to the design drawing or CAD file is pre-input into the control system. The control system will drive the cutting head to move according to these path instructions. Laser cutting: After the above preparations are completed, the actual cutting operation begins. The laser device 21 emits a high-energy laser beam, which acts on the workpiece surface after being focused by the focusing mirror and cuts according to the predetermined path. At the same time, the cutting head and its related components will move in the X, Y, and Z directions to adapt to the cutting requirements of different shapes and sizes.

[0059] Specifically, to achieve the coaxial setting of the industrial camera 23 and the laser beam, the cutting device 2 further includes a first optical path reflection component 25, which is located above the cutting head component 22. The industrial camera 23 is connected to the first optical path reflection component 25. The first optical path reflection component 25 guides the parallel beam of the industrial camera 23 to the axis where the laser beam is located. The first optical path reflection component 25 can be a 45° mirror.

[0060] Further, to achieve the coaxial setting of the axis of the point light source 24 and the laser beam, the cutting device 2 further includes a second optical path reflection component 26, which is located above the cutting head, preferably between the industrial camera 23 and the cutting head component 22. The point light source 24 is connected to the second optical path reflection component 26. The second optical path reflection component 26 guides the supplementary light beam of the point light source 24 to the axis of the laser beam. Similarly, the second optical path emission component can be a 45° mirror.

[0061] Furthermore, the cutting device 2 further includes a third optical path emission component 27, which is located above the cutting head component 22. The laser 21 is connected to the third optical path reflection component 27 and is used to guide the laser beam of the laser 21 into the cutting head component 22. Similarly, the third optical path emission component 27 can be set as a 45° mirror.

[0062] The above first, second, and third optical path reflection components are respectively used to adjust the optical path directions of the industrial camera 23, the point light source 24, and the laser 21, so that they can work along the same axis, simplify the system structure, and improve the integration degree. At the same time, the axes of the laser 21, the industrial camera 23, and the point light source 24 coincide on the horizontal projection of the cutting head component 22 to enhance the compactness and stability of the system and reduce the complexity problems caused by non-coaxiality.

[0063] In one embodiment, the cutting device 2 further includes a laser distance sensor 28, which is located on the cutting head component 22 and is used to measure the distance between the cutting head and the workpiece to be cut, ensure a constant working distance, and further improve the cutting quality and consistency.

The Z-axis execution assembly 33 is used to fix the cutting device 2.

When the X-axis servo driver receives the signal sent by the motion controller, it is processed into a corresponding electrical signal and given to the motor stator inside the X-axis servo linear motor.

After being processed into a corresponding electrical signal, it is given to the motor stator inside the Y1-axis servo linear motor and the Y2-axis servo linear motor. The guide rail slider mechanisms inside the Y1-axis servo linear motor and the Y2-axis servo linear motor respectively serve as the guides for the Y1-axis movement direction and the Y2-axis movement direction. The grating rulers inside the Y1-axis servo linear motor and the Y2-axis servo linear motor are used as the position feedback signals of the axis movement and fed back to the Y1-axis servo driver and the Y2-axis servo driver for position correction.
