[0024] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only an embodiment of a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0025] Embodiment 1

[0026] See also Figure 1-Figure 3 This embodiment provides a laser engraving method for the texture of an automobile interior decoration part 2, including step S101, step S102 and step S103.

[0027] S101, when it is detected that an automobile interior decoration part 2 is placed on a fixture 10 of a workpiece processing station of a laser engraving machine 1, a visual lens assembly 11 disposed above the workpiece processing station of the laser engraving machine 1 is controlled to photograph the automobile interior decoration part 2 to obtain an interior decoration part placement image reflecting a fixed position of the automobile interior decoration part 2 on the fixture 10;

[0028] S102, analyzing the placement position of the automobile interior decoration part 2 in the interior decoration part placement image, and when the placement position of the automobile interior decoration part 2 is offset, controlling the precision UVW visual alignment platform under the jig of the laser engraving machine to correct the placement position of the automobile interior decoration part on the jig; when the placement position of the automobile interior decoration part 2 is accurate, controlling the chassis door 12 of the laser engraving machine 1 to close;

[0029] S103. When it is detected that the chassis door 12 of the laser engraving machine 1 is closed, the laser engraving machine 1 is controlled to laser engrave the automobile interior decoration part 2 along a preset laser engraving path, and the pulse smoke remover 3 located on one side of the laser engraving machine 1 is synchronously controlled to be turned on; the pulse smoke remover 3 is connected to the smoking device 13 arranged on the laser engraving machine 1 above the workpiece processing station to perform pulse smoke removal on the workpiece processing station.

[0030] It should be noted that, in this embodiment, when it is detected that an automobile interior decoration part 2 is placed on a jig 10 of a workpiece processing station of a laser engraving machine 1, a visual lens assembly 11 arranged above the workpiece processing station of the laser engraving machine 1 is controlled to photograph the automobile interior decoration part 2 to obtain an interior decoration part placement image reflecting a fixed position of the automobile interior decoration part 2 on the jig 10, and the placement position of the automobile interior decoration part 2 in the interior decoration part placement image is analyzed. When the placement position of the automobile interior decoration part 2 is offset, the precision UVW visual alignment platform 18 under the jig of the laser engraving machine is controlled to correct the placement position of the automobile interior decoration part on the jig. When the placement position of the automobile interior decoration part 2 is accurate, The chassis door 12 of the laser engraving machine 1 is controlled to be closed. When it is detected that the chassis door 12 of the laser engraving machine 1 is closed, the laser engraving machine 1 is controlled to laser engrave the automobile interior decoration part 2 along a preset laser engraving path, and the pulse smoke remover 3 located on one side of the laser engraving machine 1 is synchronously controlled to be turned on. The pulse smoke remover 3 is connected to the smoking device 13 arranged above the workpiece processing station on the laser engraving machine 1 to perform pulse smoke removal on the workpiece processing station, thereby not only improving the processing efficiency of the texture of the automobile interior decoration part 2, reducing costs, and performing environmentally friendly processing, but also correcting the workpiece placement position through visual alignment, so that the texture processing position of the automobile interior decoration part 2 is accurate, thereby improving the texture processing accuracy of the automobile interior decoration part 2.

[0031] In step S101, the automobile interior decoration part 2 is photographed by the visual lens assembly 11, and the placement position image of the interior decoration part on the fixture 10 can be obtained in real time, providing an automated, contactless way to detect the position of the interior decoration part. Through this automatic detection, the error of manual alignment can be avoided, and the accuracy and speed of the position detection of the interior decoration part can be improved, thereby laying the foundation for subsequent precise engraving. This automatic detection method not only improves processing efficiency, but also reduces manual intervention, thereby reducing operating costs. In some preferred embodiments, a photoelectric sensor is installed on the edge of the fixture 10, and the photoelectric sensor emits a light beam. When the automobile interior decoration part 2 is placed, the light beam is blocked to generate a changing light signal. The photoelectric sensor detects the changing light signal to detect that the automobile interior decoration part 2 is placed on the fixture 10 of the workpiece processing station of the laser engraving machine 1.

[0032] In step S102, the placement image of the interior parts obtained by the camera is analyzed to determine whether the automobile interior parts 2 are placed accurately. If position deviation is found, the precise UVW visual alignment platform 18 under the jig of the laser laser engraving machine is controlled to correct the placement position of the automobile interior parts on the jig to ensure that each automobile interior part 2 is in the correct position before processing, reducing the processing error that may be caused by position deviation, thereby improving the accuracy of texture engraving. Through this precise alignment correction, not only can the processing accuracy be improved, but also the scrap rate can be reduced, and the material and processing costs can be reduced.

[0033] In step S103, after confirming that the chassis door 12 is closed, laser engraving of the automobile interior decoration part 2 begins with a preset laser engraving path to ensure the standardization and consistency of each processing. At the same time, the pulse smoke remover 3 is started synchronously, and the smoke generated during the processing is effectively removed by the smoking device 13, which not only improves the cleanliness of the processing environment and meets environmental protection requirements, but also reduces pollution to the equipment and maintenance costs. It should be noted that in this embodiment, laser engraving only starts after the chassis door 12 is closed, and the smoking device 13 is connected to the synchronously started pulse smoke remover 3, so that the smoke is removed inside the chassis 16 to prevent the external air from being polluted and endangering human health. Further, the automobile interior decoration part 2 is an irregular substrate in the shape of a long strip, and the irregular substrate in the shape of a long strip includes a first edge texture engraving area, a middle texture engraving area, and a second texture edge texture engraving area; the engraving area areas of the first edge texture engraving area, the middle texture engraving area, and the second texture edge texture engraving area are increased in sequence, the first edge texture engraving area is located on the left side of the middle texture engraving area, and the second texture edge texture engraving area is located on the right side of the middle texture engraving area; the jig 10 is a rectangular jig 10, which is used to fit the irregular substrate in the shape of a long strip, and the smoking device 13 is a long smoking device 13, and the extension length of the long smoking device 13 above the workpiece processing station exceeds the length of the irregular substrate in the shape of a long strip. It should be noted that the irregular substrate in the shape of a long strip usually has a long length and an irregular shape, which increases the difficulty of fixing and positioning on the jig 10. By designing a specific shape of the jig 10 (rectangular jig 10) to adapt to such an irregular substrate, the substrate can be stably placed on the jig 10, thereby improving the accuracy during the engraving process. Irregular substrates in the shape of long strips often require different areas to be processed with different degrees of texture. Therefore, by zoning different areas, it helps to ensure that each area obtains a suitable engraving effect and avoids uneven processing due to irregular shapes. The sequential increase in area helps to control the time of different areas during the processing. In addition, the rectangular fixture 10 is adapted to the substrate in the shape of a long strip, ensuring that the substrate can be stably and accurately fixed on the fixture 10, providing uniform support, and helping to improve the flatness and position accuracy of the substrate during the engraving process, thereby ensuring the accuracy of texture engraving. In addition, the extended length of the long strip smoking device 13 exceeds the length of the long strip substrate, which means that smoke can be effectively absorbed throughout the substrate processing area. Especially in the large-area engraving process, the long strip smoking device 13 can evenly cover the length of the entire workpiece, ensuring that smoke in all engraving areas is removed in time, and preventing smoke accumulation from having a negative impact on the processing environment and engraving quality.By providing the long strip smoking device 13, the deposition of smoke and dust can be effectively avoided, which not only helps to protect the cleanliness and stability of the processing equipment, but also improves the overall processing quality and meets the requirements of environmentally friendly processing. Further, the automobile interior decoration part 2 is a glass screen of the automobile central control and instrument panel; the preset laser engraving path is used to remove the ink layer of the VA area of ​​the glass screen of the automobile central control and instrument panel, so that there is no residue after the ink is removed and the glass surface of the glass screen of the automobile central control and instrument panel cannot be damaged.

[0034] In some preferred embodiments, when it is detected that the chassis door 12 of the laser engraving machine 1 is not closed, a prompt is given to check whether the closing function of the chassis door 12 is faulty. It should be noted that the laser engraving machine 1 generates a high-energy laser beam when it is working. If the chassis door 12 is not closed, the laser may leak out, causing serious safety hazards to the operator. By setting a prompt function, it is ensured that laser engraving will not be started when the chassis door 12 is not closed, thereby effectively preventing accidents and protecting the safety of the operator.

[0035] In some preferred embodiments, the laser engraving machine 1 includes a machine table 14 and a frame 15; the frame 15 is arranged on the table of the machine table 14, and a material handling table 140 is reserved on the table of the machine table 14, and the fixture 10 of the workpiece processing station is arranged on the material handling table 140. It should be noted that setting the frame 15 on the table of the machine table 14 helps to optimize the spatial layout of the equipment, make the entire laser engraving machine 1 compact, reduce the workshop space occupied by the equipment, help simplify the installation and maintenance of the equipment, and also help to improve the stability and reliability of the system. A material handling table 140 is reserved on the table of the machine table 14, and the fixture 10 is arranged on the table, so that the workpiece is more convenient and quick to take and put. The operator can directly perform material handling operations on the processing table, reduce unnecessary movement and operation steps, and improve work efficiency.

[0036] In some preferred embodiments, the laser engraving machine 1 further includes a chassis 16; the chassis 16 is mounted on the machine table 14, and when the chassis door 12 of the chassis 16 is closed, the frame 15, the material handling table 140 and the fixture 10 of the workpiece processing station are enclosed on the table of the machine table 14. It should be noted that a high-energy laser beam will be generated during the laser engraving process, which poses a potential safety risk. The chassis 16 is designed to seal the laser source during the processing process to prevent the laser from leaking and ensure the safety of the operator. By closing the chassis door 12, the laser is completely confined in a closed space to avoid laser damage to personnel or peripheral equipment. In addition, during the laser engraving process, some tiny smoke and dust will be generated. The closed design of the chassis 16 can effectively prevent smoke and dust from overflowing and keep the working environment clean and safe.

[0037] In some preferred embodiments, the laser laser engraving machine 1 further includes a laser laser engraving assembly 17; the laser laser engraving assembly 17 is arranged at the top of the frame 15, and is used to perform laser engraving of a preset laser engraving path on the automotive interior parts 2 when the chassis door 12 of the laser laser engraving machine 1 is closed. The frame 15 includes a bottom box 150, a middle box 151 and a top box 152 connected in sequence from bottom to top; the bottom box 150 is connected to the table of the machine 14; the laser laser engraving assembly 17 is arranged on the upper surface of the top box 152, and the bottom box 150, the middle box 151 and the top box 152 are superimposed together to form the working range of the laser laser engraving assembly 17. It should be noted that through the superimposed structure of the bottom, middle and top boxes 152, a working space that expands layer by layer from bottom to top can be formed. This design allows the laser laser engraving assembly 17 to cover a larger space, so that flexible engraving operations can be performed at different heights and positions. For irregularly shaped automotive interior parts 2, this structure can provide great processing flexibility and precision control. In addition, the layered design allows each layer of the box to be disassembled and maintained independently, which is convenient for equipment maintenance and troubleshooting. If the laser engraving component 17 or other components need to be repaired or upgraded, they can be processed directly on a specific layer without having to fully disassemble the entire device.

[0038] In some preferred embodiments, the fume extractor 13 is arranged at the front side of the middle box 151, and the front side of the middle box 151 is the side facing the workpiece processing station; the fume extractor 13 is connected to the pulse fume extractor 3 through a connecting pipe, and the pulse fume extractor 3 is arranged at the rear side of the laser engraving machine 1, and the connecting pipe passes through the front side of the middle box 151 and passes out of the rear side of the middle box 151 to communicate with the pulse fume extractor 3. It should be noted that in this embodiment, the fume extractor 13 is arranged at the front side of the middle box 151, which means that the fume extractor 13 is very close to the smoke and exhaust gas source generated by laser engraving, and can quickly absorb the smoke at the moment of generation, reduce the diffusion of smoke in the air, maximize the absorption efficiency of the fume extractor 13, help keep the processing environment clean, and prevent pollutants from affecting the accuracy of laser engraving and the quality of the workpiece surface. The connecting pipe passes through the middle box 151 from the front side, passes out from the back side of the middle box 151, and is finally connected to the pulse smoke remover 3, making the entire smoke removal system more compact. At the same time, it also effectively utilizes the space inside the laser engraving machine 1, avoids the pipe being exposed around the equipment, and reduces the occupied workshop space.

[0039] In some preferred embodiments, the visual lens assembly 11 is arranged on the front side of the top box 152, located above the smoking device 13, so as to be separated from the workpiece processing station by a preset anti-pollution height, and the front side of the top box 152 is the side facing the workpiece processing station. It should be noted that pollutants such as smoke and dust will be generated during the laser laser engraving process, and these pollutants may affect the clarity of the visual lens. If the lens assembly is set at a lower position or too close to the workpiece processing station, it is easy to be directly affected by these pollutants, resulting in contamination of the lens surface and affecting the shooting effect. By setting a preset anti-pollution height, the interference of these pollutants can be effectively avoided, ensuring a clear field of view of the lens, thereby ensuring the quality and accuracy of image capture. In addition, it can also prevent pollutants from being deposited on the lens, reducing the cleaning frequency and maintenance requirements of the lens, thereby extending the service life of the lens assembly and reducing the maintenance cost of the equipment. The visual lens assembly 11 is arranged on the front side of the top box 152 and above the smoking device 13, which not only ensures that the lens can directly observe the situation of the workpiece processing station from the best viewing angle, but also avoids the direct smoke generated during the workpiece processing, thereby improving the accuracy and reliability of visual detection.

[0040] In some preferred embodiments, the laser engraving assembly 17 includes an X-axis assembly 170, a Z-axis assembly 171, and a laser galvanometer 172 with a laser scanner; the X-axis assembly 170 is arranged on the upper surface of the top-level box 152, and the Z-axis assembly 171 connects the laser galvanometer 172 with a laser scanner and the X-axis assembly 170; the X-axis assembly 170 drives the Z-axis assembly 171 and the laser galvanometer 172 with a laser scanner to move in the X-axis direction, and the Z-axis assembly 171 drives the laser galvanometer 172 with a laser scanner to move in the Y-axis direction, and the laser galvanometer 172 with a laser scanner is used to perform laser engraving of the automobile interior decoration 2 in a preset laser engraving path. It should be noted that the X-axis assembly 170 is arranged on the upper surface of the top-level box 152, and the horizontal length of the interior decoration can be covered by controlling the movement of the laser galvanometer in the X-axis direction. Such a design allows the laser to be precisely positioned and scanned on the X-axis, ensuring that the laser beam can move precisely on the horizontal plane of the workpiece, thereby achieving high-precision engraving. The Z-axis assembly 171 connects the laser galvanometer and the X-axis assembly 170, and is responsible for moving the laser galvanometer on the Z-axis (vertical direction), which can change the height of the laser focus point to adapt to workpieces of different thicknesses or heights. In addition, the laser galvanometer 172 with a laser scanner can quickly adjust the direction of the laser beam to achieve high-speed, high-precision scanning and engraving.
