Description

Technical Field

[0001] This application relates to the field of laser cutting technology, and in particular to equipment for multi-axis linkage laser beam processing of marble. Background Technology

[0002] Traditional processing equipment currently on the market has many limitations. Its processing technology is often relatively simple, its processing precision is unsatisfactory, its stability is poor, and its functional configuration is not comprehensive. These problems directly lead to low processing efficiency, unnecessarily extended production cycles, low levels of automation, and excessive reliance on manual operation. Product quality depends mainly on manual control, resulting in large quality fluctuations, difficulty in improving the pass rate, and consequently affecting the product's appearance, structural stability, and making it prone to vibration and other problems.

[0003] Furthermore, over-reliance on manual operation not only reduces production efficiency but also increases the risk of workplace injuries, posing certain safety hazards. Traditional processing equipment also suffers from insufficient compatibility and low space utilization, which not only leads to increased energy consumption but also results in material waste due to excessive processing allowances, further driving up processing costs.

[0004] More worryingly, traditional processing equipment has limited processing precision, making it difficult to achieve micron-level accuracy requirements. Furthermore, the processing process is prone to defects such as burrs and collapses, negatively impacting product quality and performance. At the same time, this equipment may also generate significant pollution during operation, adversely affecting the environment.

[0005] In conclusion, traditional processing equipment can no longer meet the needs of modern manufacturing in many aspects and urgently needs technological upgrading and transformation. Utility Model Content

[0006] To address the issues of low processing precision, low efficiency, poor stability, susceptibility to vibration, incomplete functionality, high labor costs, low compatibility, and low space utilization, this application provides a multi-axis linkage laser beam processing equipment for marble.

[0007] The marble multi-axis linkage laser beam processing equipment provided in this application adopts the following technical solution:

[0008] A marble multi-axis linkage laser beam processing equipment includes a table and an integrated sheet metal cabinet that supports the entire device. On the side of the table away from the integrated sheet metal cabinet, there are Y-axis and X-axis moving devices that move the workpiece in space. On one side of the table, there are legs and a crossbeam to improve stability. On the side of the crossbeam away from the legs, there is a laser. On one side of the laser, there is a beam expander to convert the diverging beam into a parallel beam. On one side of the beam expander, there are several sealed tubes to reduce energy loss of the laser during path transmission. Reflectors to change the direction of beam transmission are fixed between the sealed tubes.

[0009] A Z-axis moving device is provided on one side of the crossbeam, a galvanometer is provided on one side of the Z-axis moving device for continuously deflecting light, a field mirror is provided on one side of the galvanometer for focusing the deflected light, and a reflection module for transmitting laser light to the galvanometer is provided on one side of the Z-axis moving device.

[0010] By adopting the above technical solution, the device integrates Y-axis, X-axis and Z-axis moving devices, as well as key components such as laser, beam expander, sealing tube, and reflector, forming a high-efficiency and precise laser processing system. The combination design of the table and the integrated sheet metal cabinet not only provides stable support, but also optimizes the space layout, making the entire device compact and easy to operate.

[0011] Preferably, a display is provided on one side of the integrated sheet metal cabinet, so that the control and detection during the processing can be adjusted and planned through the software inside the display.

[0012] By adopting the above technical solution, the movable stand design on one side of the monitor allows users to flexibly adjust the position and angle of the monitor according to actual needs, further improving the comfort and convenience of operation.

[0013] Preferably, the display is provided with a movable frame on one side that is fixedly connected to the integrated sheet metal cabinet, and the movable frame is used to flexibly adjust the display.

[0014] By adopting the above technical solution, the fixed connection design between the movable frame and the integrated sheet metal cabinet ensures the stability and safety of the monitor. At the same time, the flexible adjustment function of the movable frame allows the monitor to adapt to different working environments and operational needs, further enhancing the practicality and flexibility of the entire device.

[0015] Preferably, the integrated sheet metal cabinet is internally fitted with a square tube frame that has strong load-bearing capacity and stability.

[0016] By adopting the above technical solution, the square tube frame fixed inside the integrated sheet metal cabinet not only enhances the load-bearing capacity and stability of the cabinet, but also optimizes the internal structural layout of the cabinet, enabling the cabinet to carry more equipment and components, while ensuring the long-term stable operation of the entire device.

[0017] Preferably, both the Y-axis moving device and the X-axis moving device are provided with a drag chain on one side to bind the wires and facilitate their movement.

[0018] By adopting the above technical solution, the drag chains set on one side of the Y-axis moving device and the X-axis moving device effectively bind the wires and facilitate their movement. This not only reduces the risk of wear and damage to the wires, but also ensures the safety and stability of the wires during movement, thereby improving the reliability and durability of the entire device.

[0019] Preferably, the crossbeam is fixed with a protective shell on the side away from the support leg to protect the laser, beam expander, sealing tube and reflector from dust.

[0020] By adopting the above technical solution, the protective shell fixed on the side of the crossbeam away from the support leg effectively protects and dusts key components such as the laser, beam expander, sealing tube, and reflector. This not only extends the service life and performance stability of these components, but also ensures the accuracy and reliability of the entire laser processing system.

[0021] Preferably, the beam expander is externally fixed with a beam expander adjustment frame that is fixed to the crossbeam, and the beam expander adjustment frame is used to support the beam expander.

[0022] By adopting the above technical solution, the fixed connection design between the beam expander adjustment frame and the crossbeam on the outside of the beam expander provides stable support for the beam expander, which not only ensures the accuracy and stability of the beam expander, but also facilitates the user's adjustment and maintenance of the beam expander.

[0023] Preferably, the side of the crossbeam away from the protective shell is fixed with a mounting plate for supporting and fixing the Z-axis moving device and the reflection module.

[0024] By adopting the above technical solution, the mounting plate fixed on the side of the crossbeam away from the protective shell effectively supports and fixes components such as the Z-axis moving device and the reflection module. This not only optimizes the layout and installation position of these components, but also ensures their stability and reliability during operation, thereby improving the performance and precision of the entire laser processing system.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By utilizing the Y-axis, X-axis, and Z-axis moving devices in coordination to form a multi-axis linkage effect, complex machining trajectories can be achieved, thereby realizing high-precision and high-efficiency linkage machining. It is also equipped with a drag chain to effectively manage the line running trajectory.

[0027] 2. By using the square tube frame and the integrated sheet metal cabinet to weld the sheet metal into an integrated structure, it has high mechanical strength and stability. While ensuring that the basic functions are met, the overall model presents a good texture and a simple and elegant appearance. The control and detection during the processing are adjusted and planned through the display software, and the movable frame facilitates personnel operation.

[0028] 3. The laser emitted by the laser is shaped by the beam expander 2, reaches the reflector, and is transmitted inside the sealed tube. After being focused by the Z-axis moving device and deflected by the galvanometer, and finally focused by the field lens, it is presented on the processing surface, realizing planar processing within a certain range. The equipment table adopts a double-layer marble structure, consisting of a crossbeam, two legs and a table, which has strong structural stability, is economical and practical, and conforms to ergonomics.

[0039] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0040] This application discloses a multi-axis linkage laser beam processing equipment for marble.

[0041] Reference Figure 1 , Figure 2 The marble multi-axis linkage laser beam processing equipment includes a platform 100 fixed on top of an integrated sheet metal cabinet 500 that supports the entire device. Inside the integrated sheet metal cabinet 500, a square tube frame 501 is fixedly installed, and the square tube frame 501 is integrally welded to the integrated sheet metal cabinet 500, giving it strong load-bearing capacity and stability with relatively low weight. The tight welding connection ensures it can support marble and other equipment accessories. A movable frame 502 is fixedly connected to one side of the integrated sheet metal cabinet 500, and a monitor 503 is fixedly connected to the side of the movable frame 502 away from the integrated sheet metal cabinet 500. The monitor 503 can be flexibly adjusted according to the individual habits of the operator, and the software inside the monitor 503 allows for adjustment and planning of control and detection during the processing.

[0042] The integrated sheet metal cabinet 500 and the square tube frame 501 are welded together to provide a supporting skeleton for the entire device. It has high mechanical strength and structural stability, with an overall load-bearing capacity of over three tons. The thin material facilitates welding, and the overall structural design effectively distributes load pressure and reduces the risk of deformation. Compared with traditional angle steel welding, it produces less pollution during on-site construction and is easier to treat. The surface can be sprayed, polished, etc. to improve its aesthetics. Compared with aluminum profile frames, the square tube frame 501 has a cost advantage while ensuring strength. The integrated sheet metal cabinet 500 has a reasonable ventilation hole design, heat dissipation channel design, and internal sealing structure design to ensure that the equipment is kept at a safe operating temperature. The integrated sheet metal cabinet 500 has an independent and detachable power interface adapter plate at the rear. The integrated sheet metal cabinet 500 has high dimensional accuracy and is suitable for precision instrument packaging. While meeting basic functions, it can protect the equipment from external environmental pollution.

[0043] Reference Figure 1 , Figure 4A Y-axis moving device 200 is provided on the side of the table 100 away from the integrated sheet metal cabinet 500, and an X-axis moving device 201 is provided on the upper part of the Y-axis moving device 200. The Y-axis moving device 200 and the X-axis moving device 201 cooperate with each other to drive the workpiece to move in the X-axis and Y-axis directions respectively. A drag chain 202 is provided on one side of both the Y-axis moving device 200 and the X-axis moving device 201. The drag chain 202 can bind the wires that control the linear motors in the Y-axis moving device 200 and the X-axis moving device 201, so that the wires can follow the movement of the Y-axis moving device 200 and the X-axis moving device 201.

[0044] The Y-axis moving device 200 and the X-axis moving device 201 achieve planar motion through direct electromagnetic drive, with positioning accuracy reaching sub-micron level, high dynamic response speed, and repeatability error controllable within ±0.5μm. It should be noted that both the Y-axis moving device 200 and the X-axis moving device 201 need to be connected to the PLC or other controllers inside the integrated sheet metal cabinet 500. However, since these are existing technologies, their structural principles will not be described in detail here.

[0045] Reference Figure 1 , Figure 3 A support leg 101 is fixedly mounted on the surface of the platform 100 away from the Y-axis moving device 200, and a crossbeam 102 is fixedly mounted on the upper part of the support leg 101. Both the support leg 101 and the crossbeam 102 can improve the stability of the structure fixed on them. A laser 302 is fixedly mounted on the surface of the crossbeam 102 away from the support leg 101, and a beam expander 303 for converting the divergent beam into a parallel beam is fixedly connected to one side of the laser 302. The beam expander 303 is fixed to the surface of the crossbeam 102 by a beam expander adjustment frame 301, which provides stable support for the beam expander 303 and prevents deviation of the beam expander 303 due to vibration or other reasons. Several sealing tubes 304 are fixedly connected to the side of the beam expander 303 away from the laser 302. The sealing tubes 304 can reduce the energy loss of the laser during the path transmission process. The sealing tubes 304 are arranged in a U-shape. Figure 3 As shown, a reflector 305 for changing the beam transmission direction is fixedly installed at the bend between several sealing tubes 304, so that the beam can change the transmission direction through the reflector 305. A protective shell 300 is provided on the outside of the laser 302, the beam expander 303, the sealing tubes 304 and the reflector 305, and the protective shell 300 is fixedly connected to the side of the crossbeam 102 away from the support leg 101.

[0046] The outriggers 101 and crossbeams 102 have high density and a hardness exceeding HS70, far surpassing that of cast iron and other metals. They are highly wear-resistant, not easily deformed, and can maintain high precision and stability over long periods. Their surfaces are not easily damaged, their physical properties are stable, and they have high compressive strength, enabling them to withstand various vibration environments. Furthermore, they exhibit strong resistance to acids and alkalis, have low maintenance costs, and are recyclable.

[0047] The laser source uses a picosecond infrared laser 302, which offers a significant improvement in processing quality compared to nanosecond lasers. Compared to femtosecond lasers, it has advantages in stability and cost, making it suitable for various complex industrial scenarios and further improving processing quality. The diameter of some laser spots can be reduced to the micrometer level, achieving extremely high processing precision. The beam expander has a small volume and no intermediate focal point. The laser beam expander 303, through beam parameter adjustment and optical performance optimization, solves problems such as large divergence angle and uneven energy distribution during laser transmission from the laser 302. Suitable for high-precision designs, the beam exiting the beam expander 303 is reflected by the laser reflector 305. The reflector 305, acting as a folding or deflecting mirror, can change the beam transmission direction, optimize the optical path and overall mechanical structure layout, save equipment and factory space, and improve economic efficiency. Combined with a focusing mirror, it forms a compact optical path system. The mirror surface has a special coating, solving core issues such as beam control, energy loss, and environmental adaptability, resulting in high stability, compatibility, and maintainability.

[0048] The laser beam path is sealed by a mechanical cylindrical threaded component, also known as a 304 sealing tube. The fully enclosed design prevents laser leakage, avoiding harm to the human body and the surrounding environment. It also reduces energy loss during laser transmission, prevents damage to optical lenses from dust and impurities generated during laser processing, further improves processing accuracy, effectively isolates external pollutants, and reduces the frequency of maintenance and lens replacement.

[0049] Reference Figure 1 , Figure 5 The beam 102 is fixedly connected to the mounting plate 400 on the side away from the protective shell 300. A Z-axis moving device 401 is fixedly installed on the side of the mounting plate 400 away from the beam 102. The moving end of the Z-axis moving device 401 away from the mounting plate 400 is fixedly connected to the galvanometer 403, which is used to continuously deflect light, through a connector. The Z-axis moving device 401 can drive the galvanometer 403 to move longitudinally back and forth. A field mirror 404 is fixedly installed on one side of the galvanometer 403. The field mirror 404 can focus the light deflected by the galvanometer 403. A reflection module 402 is installed on one side of the Z-axis moving device 401. The reflection module 402 is connected to the sealing tube 304 to transmit the laser reflected by the reflector 305 to the galvanometer 403 for refraction.

[0050] It should be noted that the Z-axis moving device 401, the reflection module 402, the galvanometer 403, and the field lens 404 are all existing technologies, and their structural principles will not be described in detail here. Furthermore, the Z-axis moving device 401 is also equipped with a linear motor, which also needs to be connected to the PLC controller in the integrated sheet metal cabinet 500. However, since these are all existing technologies, their structural principles will not be described in detail here.

[0051] The Z-axis moving device 401 adopts a corrugated cover sealing method, which combines flexibility and sealing function. The corrugated cover is made of multi-layer elastic material to form a pleated structure, which can achieve flexible deformation in the Z-axis direction to compensate for the small displacement in the Z-axis direction during the operation of the laser equipment. It can flexibly integrate into narrow spaces and reduce the overall weight of the equipment. The corrugated cover has flexible deformation capability, high sealing performance and resistance to extreme environments.

[0052] The independent Z-axis moving device 401 can drag the galvanometer 403 and the field mirror 404, adjusting the height in the Z-axis direction within the stroke range, thereby adjusting the position of the laser processing focus. It can be flexibly adjusted according to the working conditions and the height and position of the workpiece. The Z-axis moving device 401 can stably withstand large loads, with a repeatability accuracy within ±0.02, high processing accuracy, and smooth operation. It works in conjunction with the Y-axis moving device 200 and the X-axis moving device 201 to form a multi-axis linkage effect, realizing complex processing trajectories. The X-axis moving device 201, the drag chain 202, and the Z-axis moving device 401 achieve planar and longitudinal movements through direct electromagnetic drive, with positioning accuracy reaching sub-micron level and high dynamic response speed. For example, the repeatability error can be controlled within ±0.5μm.

[0053] The implementation principle of the marble multi-axis linkage laser beam processing equipment in this application embodiment is as follows: First, the equipment is powered on. The equipment is turned on using the switch button below the display 503. The workpiece is manually placed on the X-axis moving device 201 panel. Through cooperation with the Y-axis moving device 200, the linear motors in both devices can drive the workpiece to move in the X and Y axes. Simultaneously, through linkage with the Z-axis moving device 401, the field lens 404 is aligned with the workpiece processing surface. Then, a laser beam is emitted by the laser 302. After the laser beam is generated, the beam expander 303 converts the divergent beam output by the laser 302 into a parallel beam. The collimated beam is then focused by the focusing lens to form a smaller high-resolution image. The high-density light spot is refracted by the sealed tube 304 and the reflector 305, and then transmitted to the reflector module 402. The reflector module 402 then transmits the light to the galvanometer 403. The light is continuously deflected by the mirror inside the galvanometer 403 and focused by the field lens 404, allowing for planar processing within a certain range. In conjunction with the Z-axis moving device 401, partial curved surface processing can be achieved. Due to the large amplitude during the movement, the equipment table 100 is composed of legs 101 and crossbeams 102 to ensure a heavy load and high stability, making the equipment run smoothly during processing and further improving product quality.

[0054] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
