[0002] Multi-lens laser processing equipment is a precision system that uses a combination of multiple optical lenses to guide, shape, and focus a laser beam. It is widely used in high-precision fields such as automotive manufacturing and aerospace. Through the collaboration of precision optical components (mirrors, lenses, beam splitters, etc.) and a CNC system, multi-lens laser processing equipment achieves high energy density and flexible multi-station processing.

[0003] In existing technologies, when multi-lens laser processing equipment performs laser cutting on highly reflective materials (such as copper, aluminum, and mirror-finished stainless steel), the highly reflective material reflects some of the incident laser energy, and the reflected laser beam may return to the laser, especially fiber lasers or solid-state lasers. This reflection can damage the internal optical components of the laser, such as the laser resonator, lenses, and mirrors, shortening the equipment's lifespan. Summary of the Invention

[0051] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0052] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0053] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0054] Example 1:

[0055] This invention provides a multi-lens laser processing device, such as... Figures 1 to 10 As shown, it includes: a laser processing component 10, an adjustment component 20, a first moving component 30, and a second moving component 40; the laser processing component 10 includes a laser head 11 for outputting a laser beam and performing laser cutting on the object being processed, the laser head 11 is arranged along a first direction, and the light-inlet end of the laser head 11 is movably connected to the first moving component 30.

[0056] The adjustment component 20 is used to move and adjust the position of the light-emitting end of the laser head 11; the first moving component 30 is used to drive the laser head 11 and the adjustment component 20 to move along the second direction; two side-by-side second moving components 40 are used to synchronously drive the first moving component 30 to move upward along the third direction; the first direction, the second direction and the third direction are set perpendicular to each other.

[0057] It should be noted that the multi-lens laser processing equipment provided by this invention specifically includes a laser processing component 10, an adjustment component 20, a first moving component 30, and a second moving component 40. By setting the adjustment component 20, the position of the laser head 11's output end can be quickly and conveniently adjusted, thereby effectively adjusting the incident angle of the laser head 11, reducing feedback from reflected laser beams, improving processing quality, and extending the equipment's service life. Since the first, second, and third directions are mutually perpendicular, the spatial layout of the equipment is optimized, enabling the equipment to achieve a wider processing range within a limited space, effectively improving the equipment's space utilization efficiency. Through the coordinated work of the first moving component 30 and the second moving component 40, precise adjustment of the laser head 11's position can be achieved, reducing the difficulty of manual operation and improving the equipment's automation level. This invention can be widely applied to laser processing of various materials, meeting the laser cutting requirements of different industries, possessing good versatility and adaptability, and suitable for large-scale production and personalized customization processing needs. Therefore, this invention solves the technical problem of laser damage caused by reflected laser beams generated when cutting highly reflective materials.

[0058] like Figures 1 to 3 As shown, the first moving component 30 includes a first moving stage 31 and a first moving frame 32 connected to the second moving component 40. A first moving motor (not shown) is mounted on the first moving frame 32 for driving the first moving stage 31 to move along a second direction.

[0059] The first moving stage 31 includes a first slider 311 slidably connected to the first moving frame 32. A first mounting plate 312 is fastened to the first slider 311, and a second mounting plate 313 is fixedly connected to the first mounting plate 312. In this embodiment, the sliding of the first moving stage 31 is achieved by pulling with a first belt 33, and a mounting cover 315 is fixedly mounted on the first mounting plate 312. A mounting frame 316 is provided between the first slider 311 and the first mounting plate 312. By setting the mounting frame 316, the height of the first mounting plate 312 in the first direction can be raised, and the installation stability of the first mounting plate 312 can be improved, thereby reducing vibration and ensuring the smooth movement of the laser head 11 during processing.

[0060] It should be noted that by adjusting the speed and direction of the first moving motor, the movement range and position of the first moving stage 31 can be precisely controlled to adapt to different processing requirements and meet diverse laser cutting tasks. The first moving motor is driven by the first belt 33, which not only achieves efficient power transmission but also simplifies the system's maintenance and replacement process. Due to the relatively simple replacement and maintenance of the first belt 33, equipment downtime can be reduced, ensuring the reliability and availability of the equipment during long-term operation.

[0061] like Figures 4 to 8 As shown, the adjustment assembly 20 includes an adjustment member 21 and an adjustment cylinder 22. One end of the adjustment member 21 is in contact with the laser head 11, and the other end of the adjustment member 21 is slidably connected to the first slider 311.

[0062] The adjusting cylinder 22 is used to drive the adjusting component 21 to move so that the light-emitting end of the laser head 11 is away from the first slider 311.

[0063] It should be noted that the adjustment cylinder 22 drives the adjustment component 21 to move, allowing the light-emitting end of the laser head 11 to flexibly move away from or towards the first slider 311. This structure enables the laser head 11 to be quickly and accurately adjusted during processing, thereby meeting the needs of different processed materials and thicknesses, and improving cutting efficiency and quality. Real-time movement of the adjustment component 21 is achieved by controlling the movement of the adjustment cylinder 22, allowing for precise control of the laser head 11's displacement. Due to the fast response speed of the adjustment cylinder 22, the adjustment of the laser head 11 is highly coordinated with the overall processing progress of the equipment, reducing malfunctions and downtime, and improving work efficiency.

[0064] like Figures 4 to 8 As shown, the adjustment assembly 20 also includes an adjustment block 23, and the adjustment cylinder 22 is mounted on the second mounting plate 313. The telescopic rod of the adjustment cylinder 22 is fixedly connected to the adjustment block 23.

[0065] The first slider 311 has a T-shaped groove 3111. The end of the adjusting block 23 away from the adjusting cylinder 22 passes through the first mounting plate 312 and abuts against the adjusting member 21. A return spring 24 is installed in the groove 3111. One end of the return spring 24 is fixedly connected to the groove 3111, and the other end of the return spring 24 is connected to the adjusting member 21. In specific implementation, the first mounting plate 312 has a through hole 3121 for accommodating the adjusting block 23.

[0066] It should be noted that the adjusting cylinder 22 is fixedly connected to the adjusting block 23 via a telescopic rod, allowing the driving of the adjusting cylinder 22 to directly affect the movement of the adjusting block 23, thereby achieving precise force transmission to the adjusting component 21. This transmission mechanism ensures that the laser head 11 is stable and reliable during each adjustment, avoiding processing errors caused by uneven force transmission. The reset spring 24 automatically returns the adjusting component 21 to its default position when the adjusting cylinder 22 is not applying power. This provides the equipment with excellent self-adaptive capabilities, effectively ensuring the safety and stability of the equipment in idle states. Due to the rapid extension and retraction of the adjusting cylinder 22 and the self-recovery characteristic of the reset spring 24, the adjusting assembly 20 can achieve a faster and more efficient adjustment process, greatly improving the equipment's working efficiency. In high-intensity practical applications, it can complete precise laser cutting tasks in a shorter time, meeting the needs of modern production.

[0067] like Figures 4 to 8 As shown, the adjusting member 21 includes a first adjusting part 211 and a second adjusting part 212 connected to each other. The first adjusting part 211 is arranged in an arc shape and abuts against the light-emitting end of the laser head 11. The second adjusting part 212 is arranged in a square shape and is slidably connected in the slide groove 3111. In this embodiment, the first adjusting part 211 and the second adjusting part 212 are integrally formed structures.

[0068] The reset spring 24 is connected to the second adjustment part 212. The adjustment block 23 is provided with a first inclined surface 231, and the second adjustment part 212 is provided with a second inclined surface 2121 that contacts the first inclined surface 231. In this embodiment, when the incident angle of the laser head 11 is 0 degrees, the angle between the laser beam output by the laser head 11 and the normal to the surface of the object being processed is 0 degrees.

[0069] It should be noted that when the incident angle of the laser head 11 needs to be adjusted, the adjusting block 23 is moved by the adjusting cylinder 22. Since the first inclined surface 231 contacts the second inclined surface 2121, the adjusting block 23 presses against the second adjusting part 212, which in turn causes the first adjusting part 211 to move the light-emitting end of the laser head 11 away from the first slider 311, thereby changing the incident angle of the laser head 11 and reducing feedback from reflected laser beams. Through the optimized design of the adjusting component 21, precise control of the adjustment angle makes energy transfer during laser cutting more efficient and the laser beam focusing more precise. This greatly improves the efficiency of laser processing, ensures high standards of cutting quality, reduces post-processing workload, and improves overall production efficiency.

[0070] like Figures 4 to 8As shown, the light-inlet end of the laser head 11 is fitted with a sleeve 314 that is rotatably connected to the second mounting plate 313, and the light-inlet end of the laser head 11 is provided with a light inlet 111; in the specific implementation process, the outer wall of the laser head 11 is provided with an arc-shaped boss 113, and the boss 113 overlaps on the sleeve 314.

[0071] The sleeve 314 is provided with a light-passing hole 3141 corresponding to the light inlet 111, and the outer wall of the laser head 11 is provided with an abutting groove 112 that abuts against the first adjustment part 211. The thickness of the abutting groove 112 in the first direction is greater than the thickness of the first adjustment part 211 in the first direction.

[0072] It should be noted that, because the light-inlet end of the laser head 11 is fitted with a sleeve 314 that is rotatably connected to the second mounting plate 313, the light-inlet end of the laser head 11 can rotate. Since the sleeve 314 is provided with a light-transmitting hole 3141 corresponding to the light-inlet 111, the laser beam can be smoothly transmitted through the light-transmitting hole 3141, thereby minimizing energy loss caused by interruption or obstruction of the beam transmission path. Because the thickness of the abutment groove 112 in the first direction is greater than the thickness of the first adjustment part 211 in the first direction, when the first adjustment part 211 extends outward along the third direction, the laser head 11 can swing smoothly, preventing motion interference.

[0073] In addition, the rotation axis of the sleeve 314 is on the same straight line as the laser beam reflected by the second reflector 14. When the laser head 11 is rotated to adjust the angle, the laser beam can smoothly enter the laser head 11, ensuring that the laser head 11 can smoothly perform laser cutting.

[0074] Specifically, the first adjusting part 211 is threadedly connected to a third adjusting part 213, and there are two third adjusting parts 213, which are used to press against the laser head 11. The third adjusting part 213 is provided with an arc-shaped pressing surface 2131, which facilitates the pressing of the third adjusting part 213 against the laser head 11. One end of the second adjusting part 212 is provided with a fourth adjusting part 214 in a semi-annular shape. The first adjusting part 211, the second adjusting part 212, the third adjusting part 213, and the fourth adjusting part 214 are all integrally formed structures. Both the first adjusting part 211 and the second adjusting part 212 are equipped with coolant, which can locally cool the light-emitting end of the laser head 11.

[0075] It should be noted that, with the third adjustment part 213, when the laser head 11 needs to maintain the corresponding incident angle for operation or angle adjustment, by rotating the third adjustment part 213, the third adjustment part 213 is pressed against the abutment groove 112, thereby locking the light-emitting end of the laser head 11, making the laser head 11 more stable during movement and ensuring processing quality.

[0076] like Figures 1 to 3 As shown, the second moving component 40 includes a second moving frame 41, on which a second moving platform 42, which is fixedly connected to the first moving component 30, is slidably connected. A second moving motor 43 for driving the second moving platform 42 to move upward along a third direction is mounted on the second moving frame 41. In this embodiment, the second moving motor 43 is driven by a second belt 44, so that the second belt 44 drives the second moving platform 42 and the first moving component 30 to move synchronously.

[0077] In this embodiment, one end of the first moving component 30 is fixedly connected to one of the second moving platforms 42, and the other end of the first moving component 30 is fixedly connected to the other second moving platform 42. In this embodiment, one end of the first moving frame 32 is fixedly connected to one of the second moving platforms 42, and the other end of the first moving frame 32 is fixedly connected to the other second moving platform 42.

[0078] It should be noted that by transmitting the drive of the second moving motor 43 to the second moving table 42 via the second belt 44, synchronous movement of the first moving component 30 and the two second moving tables 42 can be achieved. This cooperative motion mechanism greatly improves processing efficiency, enabling the equipment to quickly cover a larger area during laser cutting, effectively meeting the cutting needs of large-area materials.

[0079] like Figures 1 to 3 As shown, the laser processing assembly 10 also includes a laser generator 12, a first reflector 13 and a second reflector 14, with the first reflector 13 disposed adjacent to the laser generator 12.

[0080] The second reflector 14 is mounted on the first moving assembly 30. The first reflector 13 and the second reflector 14 are used to reflect the laser beam generated by the laser generator 12 into the laser head 11. In this embodiment, the laser generator 12 is a common device in the art, and its working principle will not be described in detail here. The laser generator 12 and the first reflector 13 are arranged along a second direction, the first reflector 13 and the second reflector 14 are arranged along a third direction, and the second reflector 14 and the laser head 11 are arranged along the second direction. The first reflector 13 and the laser generator 12 are both mounted inside the housing 50, and the second reflector 14 is located inside the second moving stage 42 and is fixedly connected to the first moving frame 32.

[0081] In this embodiment, a laser beam is output by the laser generator 12. The laser beam moves along the second direction to the first reflector 13. After the first reflection, the direction of the laser beam changes to the third direction. The first reflector 13 reflects the laser beam to the second reflector 14. The second reflector 14 reflects the laser beam into the laser head 11. After the second reflection, the direction of the laser beam changes to the second direction. At this time, the laser head 11 irradiates the workpiece with the laser beam that has been reflected twice, thereby realizing laser cutting.

[0082] It should be noted that the compact layout of the laser generator 12, the first reflector 13, and the second reflector 14 ensures efficient transmission of the laser beam within the laser processing assembly 10, optimizes the laser path, and reduces losses in the optical path, thereby maximizing the effective energy utilization of the laser and improving processing efficiency. The arrangement of the first reflector 13 and the second reflector 14 allows for adjustable laser beam reflection paths, enabling precise guidance of the laser beam into the laser head 11 as needed. Simultaneously, it effectively controls the incident angle of the laser beam, ensuring that the laser acts on the processed material at the optimal position and direction, improving processing accuracy. The modular design of the laser generator 12, reflectors, and laser head 11 allows for flexible combination and adjustment of the equipment according to different laser processing requirements; facilitating the application of different types of laser technologies and adapting to diverse needs in cutting, welding, and other laser processing techniques, thus enhancing the equipment's market adaptability.

[0083] like Figures 1 to 9 As shown, it also includes a housing 50 and a worktable 60 installed inside the housing 50, the worktable 60 being used to place the workpiece.

[0084] The laser processing component 10, the adjustment component 20, the first moving component 30 and the second moving component 40 are all installed inside the housing 50, and the two second moving components 40 are distributed on opposite sides of the worktable 60.

[0085] The workbench 60 includes a plurality of support bases 61 fixedly connected to the housing 50. Each support base 61 has a first substrate 62, a second substrate 63, and a spacer 64 arranged sequentially along a first direction. In practice, the first substrate 62 overlaps the support base 61, the second substrate 63 is spaced apart from the first substrate 62 and fixedly connected to the support base 61, and the spacer 64 overlaps the second substrate 63. The second substrate 63 has a plurality of circular holes arranged in a matrix, and the workpiece overlaps the spacer 64.

[0086] Specifically, the housing 50 is equipped with a partition 51, which divides the internal space of the housing 50 into a first cavity 52 and a second cavity 53. The first reflector 13 and the laser generator 12 are both located in the first cavity 52, while the adjustment assembly 20, the first moving assembly 30, the second moving assembly 40, and the worktable 60 are all located in the second cavity 53. The partition 51 is provided with a through hole 511 for accommodating the reflected laser beam from the first reflector 13.

[0087] It should be noted that the housing 50 effectively isolates the laser processing component 10, the adjustment component 20, the first moving component 30, and the second moving component 40, ensuring that laser radiation will not pose a safety hazard to operators or the surrounding environment during laser processing. The partition 51 divides the internal space of the housing 50 into a first cavity 52 and a second cavity 53, enhancing the safety of the operating environment. The worktable 60, including the support base 61, the first base plate 62, the second base plate 63, and the partition 64, makes efficient use of the internal space of the housing 50. This structural design allows the worktable 60 to remain stable when carrying the workpiece, improving the efficiency and adaptability of the entire equipment. The partition 64 allows dust and waste to be discharged during processing without interfering with subsequent processing.

[0088] Example 2:

[0089] This invention provides a laser processing method, applied to the multi-lens laser processing equipment as described in Embodiment 1, such as... Figure 10 As shown, it includes:

[0090] Step S1: Determine the preset incident angle of the laser head 11 according to the type of the object being processed; the type of the object being processed includes reflective materials and non-reflective materials.

[0091] Step S2: Based on the processing requirements of the object being processed, obtain the movement path of the laser head 11; the processing requirements include the cutting shape.

[0092] Step S3: Adjust the position of the light-emitting end of the laser head 11 by adjusting the component 20 to obtain the laser head 11 at the preset incident angle;

[0093] Step S4: According to the moving path of the laser head 11, the laser head 11 is driven to move accordingly by the first moving component 30 and the second moving component 40, so that the laser beam output by the laser head 11 can perform laser cutting on the object being processed.

[0094] It should be noted that by determining the preset incident angle of the laser head 11 according to the type of the object being processed (reflective and non-reflective materials), the reflection and scattering of the laser beam can be effectively reduced, thereby optimizing laser absorption on the material and improving the cutting effect and quality. The laser head 11's movement path, obtained according to the processing requirements of the object (such as the cutting shape), makes this method highly flexible and adaptable, capable of meeting cutting requirements of different shapes and complexities, thus broadening the application range of laser processing. Adjusting the position of the laser head 11's output end by moving the adjustment component 20 to achieve the preset incident angle ensures the stability and accuracy of the laser head 11 during the cutting process, ensuring that the cutting accuracy is not reduced due to laser head 11 position deviation, and lowering the error rate in the production process. Through the coordinated drive of the first moving component 30 and the second moving component 40, efficient and precise movement of the laser head 11 is achieved, maximizing processing speed and efficiency, thereby improving overall production capacity and shortening the processing cycle.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
