[0053] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0055] In one specific embodiment, the laser cutting device 2 of the laser cutting machine provided in this application 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 to 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 2mm below the nozzle of the cutting head, such as the workpiece surface, to achieve precise cutting. Specifically, the cutting head assembly 22 is equipped with a focusing lens for focusing the laser beam below the cutting head assembly 22, focusing the laser beam into a small point, increasing its energy density, thereby improving cutting efficiency and quality. The laser is emitted from the laser 21, transmitted through an optical fiber to the laser output head fixed in the cutting head, and then the optical focusing lens built into the cutting head assembly 22 refracts the parallel laser beam into a high-energy laser focused spot, with the focusing position located 2mm below the nozzle of the cutting head. The industrial camera 23 and the point light source 24 work together to image the field of view inside the nozzle of the cutting head. 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 even in low-light environments. The industrial camera 23 and the point light source 24 are used as a visual reference for horizontal positioning of the workpiece in the high-energy laser focusing spot processing. While meeting functional practicality, the use of a coaxial camera reduces mechanical errors, improves positioning accuracy, reduces the overall size of the cutting head, and facilitates the layout of other components.
[0056] Specifically, in order to achieve the coaxial arrangement of the industrial camera 23 and the laser beam, the cutting device 2 also includes a first optical path reflection component 25, which is located above the cutting head assembly 22. The industrial camera 23 is connected to the first optical path reflection component 25, and the first optical path reflection component 25 guides the parallel beam of the industrial camera 23 to the axis of the laser beam. The first optical path reflection component 25 can be a 45° reflector.
[0057] Furthermore, in order to achieve the coaxial arrangement of the axis of the point light source 24 and the laser beam, the cutting device 2 also 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 assembly 22. The point light source 24 is connected to the second optical path reflection component 26, and 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° reflector.
[0058] Furthermore, the cutting device 2 also includes a third optical path reflection component 27, which is located above the cutting head assembly 22. The laser 21 is connected to the third optical path reflection component 27 to guide the laser beam of the laser 21 into the cutting head assembly 22. Similarly, the third optical path reflection component 27 can be configured as a 45° reflector.
[0059] The first, second, and third optical path reflection components 27 are used to adjust the optical path directions of the industrial camera 23, the point light source 24, and the laser 21, respectively, so that they can work along the same axis, simplifying the system structure and improving integration. 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 assembly 22, thereby enhancing the system's compactness and stability and reducing the complexity caused by different axes.
[0060] In one embodiment, the cutting device 2 further includes a laser rangefinder 28 located on the cutting head assembly 22, used to measure the distance between the cutting head and the workpiece to be cut, ensuring a constant working distance and further improving cutting quality and consistency.

[0072] Z-axis drive assembly and Z-axis execution assembly 33. The Z-axis drive assembly is used to drive the Z-axis execution assembly 33 to move along the Z-axis.

[0073] The cutting device 2 is fixed on the stacked X, Y, Z axes and moves to realize the movement of the high-energy laser focused spot in three-dimensional space.
[0074] The X-axis drive component is an X-axis servo driver, and the X-axis execution component 31 consists of an X-axis servo linear motor and an X-axis guide rail slider mechanism. When the X-axis servo driver receives a signal from the motion controller, it processes it and converts it into a corresponding electrical signal for the stator inside the X-axis servo linear motor. The X-axis guide rail slider mechanism serves as a guide for the X-axis motion direction, and the grating ruler inside the X-axis servo linear motor serves as a position feedback signal for the axis motion, which is fed back to the X-axis servo driver for position correction.
[0075] The Y-axis drive assembly includes a Y1-axis servo driver and a Y2-axis servo driver. The Y-axis execution assembly 32 includes a Y-axis servo linear motor and a Y-axis guide rail slider mechanism. Specifically, it consists of a Y1-axis servo linear motor and a Y2-axis servo linear motor. When the Y1-axis servo driver receives the signal from the motion controller, it synchronizes it to the Y2-axis servo driver. After processing, it is converted into a corresponding electrical signal and sent to the stator of the Y1-axis and Y2-axis servo linear motors. The guide rail slider mechanism inside the Y1-axis and Y2-axis servo linear motors serves as the guide for the Y1-axis and Y2-axis movement directions, respectively. The grating ruler inside the Y1-axis and Y2-axis servo linear motors serves as the position feedback signal for the axis movement and is fed back to the Y1-axis and Y2-axis servo drivers for position correction.
[0076] In one specific embodiment, the X-axis execution component 31 provided in this application includes an X-axis servo linear motor and an X-axis guide rail slider mechanism.

The Z-axis servo linear motor is connected to the Z-axis drive assembly, the Z-axis servo linear motor is connected to the lead screw of the lead screw and nut mechanism, and the lifting platform is connected to the nut of the lead screw and nut mechanism. The Z-axis servo linear motor drives the lifting platform to move along the Z-axis.
[0079] Furthermore, the clamping fixture 4 includes:

[0082] The rotary axis drive assembly is a rotary axis stepper motor driver, and the rotary axis execution assembly 41 is a rotary motor execution mechanism; the gripper assembly 42 includes a three-jaw cylinder and grippers, which are used to fix the workpiece. The cutting moving device 3 drives the high-energy laser focusing spot of the cutting device 2 to move above the workpiece and emit light, thereby realizing the cutting of the workpiece.
[0083] When the rotary axis stepper motor driver receives a signal from the motion controller, it processes it and converts it into a corresponding electrical signal, which is then sent to the stepper motor inside the rotary motor actuator. The internal lead screw reversing structure then converts the horizontal rotational motion into vertical rotational motion, thereby achieving the motion effect along the rotary axis and realizing the rotational positioning function of the workpiece. A three-jaw cylinder, controlled by air circuit switching, works in conjunction with the grippers fixed to it to open and close, thus fixing and picking up the workpiece.
[0084] Specifically, it also includes:
[0085] The human-machine interface device includes an industrial computer and a touch screen.

[0086] In one embodiment, the human-machine interface device comprises a touchscreen, an electronic pulse generator, an industrial computer, and status indicator lights. The industrial computer, acting as the main controller of the entire device, displays the machine's software interface on the touchscreen via a data transmission line for operator settings. Signals generated by the electronic pulse generator control the individual movement of the motion axes. The status indicator lights display the current operating status of the device in real time.
[0087] In one embodiment, the body 1 consists of a support structure for fixing various components, an external sheet metal, and a laser protection structure. The square steel welded frame is the main support for all components and the external sheet metal, the angle iron welded frame is the main support for the upper part of the sheet metal, the worktable is set on the top of the square steel welded frame, and the laser protection window serves as a processing protection and observation function. The left and right pushing and pulling function of the laser protection window is realized through the structure of the guide rail slider mechanism.
[0088] The specific cutting process of a laser cutting machine includes:
[0089] The X-axis actuator 31, Y-axis actuator 32, Z-axis actuator 33, and rotary axis actuator 41 of the control cutting moving device 3 are reset;
[0090] Reset Process: This is the preparatory work before startup, ensuring that all mechanical parts return to their initial positions (usually system-defined safe positions or reference points). This ensures the accuracy and consistency of subsequent operations. X-axis actuator 31 is responsible for movement along the X-axis, Y-axis actuator 32 for movement along the Y-axis, and Z-axis actuator 33 for up-and-down movement along the Z-axis, primarily used to adjust the laser focus position. Rotary axis actuator 41 is used for workpiece rotational positioning.
[0091] The workpiece to be processed is fixed on the clamping fixture 4, and the Z-axis actuator 33 is moved to make the workpiece plane coincide with the laser focal plane to determine the workpiece zero point;
[0092] Fixing the workpiece: Use clamping fixture 4 to firmly fix the workpiece to be processed on the worktable to ensure that the workpiece will not move or vibrate during the cutting process.
[0093] Adjusting the Z-axis: By moving the Z-axis actuator 33, the position of the workpiece surface is precisely adjusted to coincide with the plane where the laser focus is located. This step is crucial for ensuring cutting quality; optimal cutting results are achieved when the laser beam is accurately focused on the workpiece surface.
[0094] Determine the workpiece zero point: Setting the origin of the workpiece coordinate system (i.e., the workpiece zero point) is crucial for programming and path planning. This point is typically determined using sensors or manually, ensuring that all subsequent movements are based on this reference.
[0095] The laser parameters are set according to the workpiece material, and the cutting moving device 3 is controlled to move the cutting device 2 according to the preset cutting route, and the laser beam of the laser 21 is controlled to cut the workpiece.
[0096] Setting Laser Parameters: Different materials require different laser power, frequency, speed, and other parameters. For example, thicker metal plates may require higher power and lower speeds, while thin plastics may require lower power to avoid scorching. Power determines the amount of laser energy, frequency affects the cutting effect in pulse mode, and speed determines the speed at which the cutting head moves, directly affecting cutting quality and efficiency. Pre-setting Cutting Path: Cutting paths generated from design drawings or CAD files are pre-input into the control system. The control system drives the cutting head to move according to these path instructions. Laser Cutting: After the above preparations are completed, the actual cutting operation begins. Laser 21 emits a high-energy laser beam, which is focused by a focusing lens and acts on the workpiece surface, cutting along the predetermined path. Simultaneously, the cutting head and its related components move in the X, Y, and Z directions to adapt to the cutting requirements of different shapes and sizes.
