[0032] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0033] This application discloses a laser thermal melting device for superhard materials.

[0036] The work platform fixture 3 consists of an X / Y motor moving platform 19, a Z-axis lifting device 20, a workpiece position adjustment device 21, a temperature sensor monitoring device 22, and a CCD vision positioning device 23.

[0037] The optical operation platform 4 consists of a support rod 11, a crossbar 12, a worktable 13, support feet 14, and casters 10. The support feet 14 are fixedly installed at the bottom of the support rod 11. The crossbar 12 and the support rod 11 are fixedly installed. A positioning plate 24 is fixedly installed on the top of the optical construction platform 2. The fixed optical path platform 15 is fixedly installed on the positioning plate 24. The connection methods of each component in this application are all well known in the art. Therefore, the specific connection methods and usage processes of each component are not described in detail.

[0038] In use, the superhard material is placed into the work platform fixture 3 and transported to the center position of the galvanometer 18 by the X / Y motor moving platform 19. The shape of the superhard material is grasped by the CCD vision positioning device 23 to achieve automatic positioning.

[0039] At this point, the line editing and positioning operations are performed using the computer's internal hot-melting software. The laser beam emitted by the laser 16 is guided by the swinging of the galvanometer 18 to perform line drawing and hot-melting. The line drawing and hot-melting drawing file is adjusted in the software to change the rotation direction. After processing, it is sent to the galvanometer 18 and the X / Y motor moving platform 19 to hot-melt the superhard material below. During the hot-melting process, the temperature is monitored in real time by the temperature sensor monitoring device 22.

[0040] The laser thermal melting equipment for superhard materials in this invention not only achieves clean processing with low noise, no pollution, and high energy efficiency, but also enables precise and automated production, making the thermal melting process more diverse and meeting higher quality requirements.

[0041] Reference Figure 3-5The equipment power control box 5 has a hinged door 9 on one side, a display screen 8 on the top of the equipment power control box 5, and corresponding first heat dissipation hole 6 and second heat dissipation hole 7 on the equipment power control box 5. The moving wheel 10 is a self-locking moving wheel, and there are four supporting feet 14 and four moving wheels 10. The supporting feet 14 are located below the moving wheels 10 and are in contact with the ground.

[0042] During use, the status can be displayed by setting up the display screen 8, and the power control box 5 can be moved by setting up the moving wheels 10, which facilitates its subsequent use and improves the convenience and flexibility of use.

[0043] Laser thermal melting equipment for superhard materials is an indispensable part of the thermal melting process, improving melting accuracy. It plays a crucial role, especially in experiments involving the testing and analysis of superhard materials. It makes superhard material thermal melting testing more convenient and precise, with a more intuitive data display interface. With the increasing maturity of laser thermal melting technology, laser thermal melting equipment for superhard materials undoubtedly possesses enormous development prospects and market potential.

[0044] During processing, a high-efficiency fume purifier effectively removes fumes and dust, achieving environmentally friendly and pollution-free processing. The machine has a built-in computer control system, allowing for direct import of pre-designed patterns for automated production, ensuring consistent results for products made from the same batch and materials. The laser uses a 250W carbon dioxide generator, which is energy-efficient and environmentally friendly, significantly reducing costs for small-batch production. Laser hot-melting accuracy is within ±0.02mm, achieving precision processing. Furthermore, the laser-melted shapes have smooth surfaces. Compared to traditional superhard material hot-melting technologies, this invented superhard material laser hot-melting equipment offers numerous significant advantages.

[0045] The superhard material laser melting equipment is equipped with an automatic camera correction function, which can automatically correct every point in the field lens distortion, greatly reducing the error at each melting position during the laser melting process. Through clamping and X / Y / Z axis fixing and adjustment, the CCD monitoring device automatically positions the equipment, and the melting accuracy error after visually grasping the superhard material is within ±0.02mm. The equipment uses temperature data detected by a temperature sensor to control parameter adjustments, enabling better melting of different superhard materials. The equipment displays various data in real time through a software interface, providing a better presentation of data performance. It uses a 10600nm continuous laser to better increase the temperature and achieve the desired superhard material melting effect. This laser equipment is equipped with its own computer system, allowing users to easily draw melting graphics using the built-in software or directly import pre-designed DXF / PLT / AI files for personalized processing, saving time and greatly improving melting efficiency.

[0046] The implementation principle of a laser thermal melting device for superhard materials in this application embodiment is as follows: When in use, the superhard material is placed in the work platform fixture 3 and transported to the center position of the galvanometer 18 by the X / Y motor moving platform 19. The shape of the superhard material is grasped by the CCD vision positioning device 23 to achieve automatic positioning.

[0047] At this point, the line editing and positioning operations are performed using the computer's internal hot-melting software. The laser beam emitted by the laser 16 is guided by the swinging of the galvanometer 18 to perform line drawing and hot-melting. The line drawing and hot-melting drawing file is adjusted in the software to change the rotation direction. After processing, it is sent to the galvanometer 18 and the X / Y motor moving platform 19 to hot-melt the superhard material below. During the hot-melting process, the temperature is monitored in real time by the temperature sensor monitoring device 22.

[0048] The focus of the laser and camera can be changed by the Z-axis lifting device 20. The accuracy of this superhard material laser thermal melting equipment is ±0.02mm. The superhard material parts after thermal melting are required to have a smooth surface.

[0049] This invention employs a high-temperature, high-absorption carbon dioxide laser with a wavelength of approximately 10600 nm. Under specific conditions, the smoothness and color of the molten material can be controlled by adjusting the output power of the laser 16 and the melting speed. Higher laser output power and slower melting speed result in better smoothness and color. Placing a high-power smoke purifier near the melting point effectively removes smoke and dust, achieving a purification rate of 99.99% for 0.3-micron particles.

[0050] The laser thermal melting equipment for superhard materials in this invention not only achieves clean processing with low noise, no pollution, and high energy efficiency, but also enables precise and automated production, making the thermal melting process more diverse and meeting higher quality requirements.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
