Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of optical lens processing, and in particular to an ultra-precision laser cutting, grinding and polishing integrated processing method and system for AI silicon carbide lenses. Background Art
[0002] AI-oriented silicon carbide lenses refer to optical lenses made of silicon carbide, which are specially designed and manufactured for artificial intelligence-related application scenarios. Silicon carbide has high hardness, high wear resistance, high thermal conductivity and excellent optical properties. At the same time, this type of lens, with its own advantages, meets the high requirements of optical imaging, sensing, display and other functions in the AI field, and is therefore widely used in AI-related equipment. When performing processing operations on AI-oriented silicon carbide lenses, such as cutting, corresponding processing equipment is usually required.
[0003] Patent application number CN105081561B discloses a focusing lens structure, a laser cutting head, and laser cutting equipment therefor. The focusing lens structure comprises a main housing, a lens barrel disposed within the housing, and a receiving space within the lens barrel; a ring-shaped retaining ring disposed within the receiving space within the lens barrel; a focusing lens embedded within the retaining ring; and a flood seal disposed over the focusing lens to secure it within the retaining ring. This invention facilitates the replacement of the focusing lens in a laser cutting head.
[0004] Patent application number CN118513947B discloses a lens grinding device, belonging to the technical field of lens processing equipment. This invention utilizes a trajectory-following mechanism to align the edge grinding die, while a front edge grinding mechanism follows the inner lens to be ground within a clamping mechanism. This allows the edged lens to more closely conform to the shape of the edge grinding die. The edge grinding mechanism can synchronously follow the surface curvature of the edge grinding die during movement, facilitating the lens to fully match the edge grinding die angle after edge grinding. This allows inexperienced personnel to quickly master the lens grinding and assembly process, improving eyeglass assembly efficiency. Furthermore, the device can adapt to different processing shapes by prefabricating an edge grinding die that matches the shape of the frame, reducing processing difficulty. Fine-tuning the relative distance from the edge grinding die allows for adaptation to frames of varying thicknesses. The flange can be used to grind grooves on the edge of the lens, allowing for simultaneous grinding of assembly grooves during edge grinding of the lens's circumference, accommodating the interlocking assembly of thinner frames and lenses, and facilitating the installation of the lens into the inner wall of the frame after edge grinding.
[0005] Although the above technical solutions have corresponding advantages, most of the current processing operations for AI silicon carbide lenses are carried out in a distributed manner. For example, traditional silicon carbide lens processing methods usually adopt step-by-step processing, that is, cutting, grinding and polishing are carried out separately. The separate processing method will make the processing process cumbersome, and manual or mechanical transfer steps need to be added in the middle. The transfer step will delay time, and the manual transfer process may be interfered by external factors and cause damage to the cut silicon carbide lenses, further leading to low processing efficiency and high production costs, affecting processing efficiency. In view of this, we propose an ultra-precision laser cutting, grinding and polishing integrated processing method and system for AI silicon carbide lenses. Summary of the Invention

The free end of the multi-freedom robot arm 2 is provided with a vacuum suction cup 23 for vacuum adsorption of the silicon carbide lens, so that the silicon carbide lens raw materials can flow in an orderly manner between various devices, realizing an integrated processing flow from cutting to grinding and polishing, and greatly improving processing accuracy and efficiency.
[0025] In this embodiment, the grinding machine case 11 and the polishing machine case 12 are both provided with a lifting dust collection assembly 4 for placing the silicon carbide lens and driving the silicon carbide lens to rise. A support frame 16 is fixedly installed on the top surface of the grinding machine case 11 and the polishing machine case 12, and two mutually symmetrical drive motors 3 are fixedly installed on the top plate of the support frame 16. A grinding wheel 33 is detachably installed at the end of the output shaft of the drive motor 3.

The front side surfaces of the grinding machine case 11 and the polishing machine case 12 are both hinged with an inspection door 131, so that the grinding machine case 11 and the polishing machine case 12 can dissipate heat in time during operation and maintain a stable internal working environment. At the same time, it is convenient for the staff to open the inspection door 131 to inspect and maintain the equipment, thereby ensuring the long-term stable operation of the equipment.
[0027] like Figure 1 and Figure 2 As shown, the free end of the multi-freedom robot arm 2 is fixedly installed with an adsorption plate 20, and a vacuum pump 21 is fixedly installed on the upper surface of the adsorption plate 20. The suction end of the vacuum pump 21 is fixedly installed with a suction pipe 22, and the end of the suction pipe 22 passes through the adsorption plate 20 from top to bottom. The vacuum suction cup 23 is located below the adsorption plate 20 and is threadedly connected to the suction pipe 22, so that the multi-freedom robot arm 2 can use the vacuum adsorption principle to firmly adsorb and fix the silicon carbide lens, and flexibly transport it between different processing equipment.

[0028] like Figure 3 As shown, a fixed disk 30 is fixedly installed at the end of the output shaft of the driving motor 3, and the grinding wheel 33 is detachably mounted on the bottom surface of the fixed disk 30, so that the grinding wheel 33 can be easily loaded and unloaded. When the grinding wheel 33 is worn or needs to be replaced with a different specification, the staff can quickly complete the replacement, thereby improving the equipment maintenance efficiency and ensuring the continuous progress of the processing work.
[0029] Specifically, two symmetrical U-shaped frames 31 are fixedly installed on the bottom surface of the top plate of the support frame 16, and a bearing seat 32 is fixedly installed on the bottom plate of the U-shaped frame 31. The output shaft of the drive motor 3 passes through the bearing seat 32 and is rotatably connected to the bearing seat 32. By setting the U-shaped frame 31 and the bearing seat 32 at the bottom of the support frame 16, the output shaft of the drive motor 3 is firmly supported during the rotation process, reducing the shaking and vibration during rotation, ensuring the smooth operation of the grinding wheel 33, and thus improving the processing quality of lens grinding and polishing.
[0030] Furthermore, the lifting and dust collection assembly 4 includes two left and right first cylinders 40 that are symmetrical to each other and fixedly mounted on the bottom wall of the exposure chamber 13, and a dust collection pipe 47 that is horizontally fixedly mounted on the side wall of the exposure chamber 13. The ends of the telescopic shafts of the two first cylinders 40 pass through the top plate of the exposure chamber 13 and are installed with side panels 411. A mesh plate 41 is fixedly installed between the two side panels 411. The mesh plate 41 is a mesh plate structure, which is used for the normal dust collection operation of the subsequent dust collection fan 471, so that the silicon carbide lens placed on the mesh plate 41 can be accurately lifted through the telescopic movement of the first cylinder 40, and the lens can be accurately delivered to the grinding or polishing position, providing a stable foundation for subsequent processing.
[0031] In addition, a bolt plate 401 is fixedly installed at the end of the telescopic shaft of the first cylinder 40, and the side plate 411 is detachably installed on the top surface of the bolt plate 401 by a plurality of fastening bolts, which is convenient for loading and unloading operations; a second cylinder 42 is fixedly installed on the top surface of the side plate 411, and a rectangular plate 421 is fixedly installed at the end of the telescopic shaft of the second cylinder 42, and a clamping plate 43 is fixedly installed on the side of the rectangular plate 421. The clamping plate 43 is used to clamp the silicon carbide lens on the mesh plate 41, so that the silicon carbide lens on the mesh plate 41 can be firmly clamped and fixed during processing, effectively preventing the lens from being displaced or shaking during the grinding process, thereby ensuring grinding accuracy and processing safety.
[0032] It is worth noting that a dust hood 44 is fixedly installed at the bottom of the mesh plate 41, which passes through the top plate of the exposure chamber 13 and is slidably connected to the top plate of the exposure chamber 13, so that the mesh plate 41 can move up and down normally; a vertical tube 45 is fixedly installed at the bottom end of the dust hood 44, and a piston 451 is detachably installed on the bottom end tube body of the vertical tube 45 through a plurality of fastening screws, and a dust suction fan 471 is fixedly installed on the inner wall of the dust suction tube 47, and the dust suction tube 47 is connected to the outside world. The dust suction fan 471 is used to generate suction to realize the dust suction operation; a vertical cylinder 46 is fixedly installed at the air inlet end of the dust suction tube 47, and a vertical sleeve 462 is fixedly installed at the top of the vertical cylinder 46, and the piston 451 is located in the vertical sleeve 462 and is slidably connected between the vertical sleeve 462, so that it will not block the normal up and down movement of the mesh plate 41.
[0033] It is worth noting that an inner sealing ring 461 is fixedly installed on the inner wall of the vertical cylinder 46, a threaded cover 48 is threadedly connected to the bottom cylinder of the vertical cylinder 46, a mesh cylinder 481 is fixedly installed on the inner wall of the threaded cover 48, and an upper cylinder 482 is fixedly installed on the top of the mesh cylinder 481. The mesh cylinder 481 and the upper cylinder 482 are plugged into the vertical cylinder 46, and the upper cylinder 482 rests on the bottom surface of the inner sealing ring 461 to ensure sealing; an inner ring 483 is fixedly installed on the inner wall of the upper cylinder 482, and a limit ring 483 is detachably installed on the upper surface of the inner ring 91. A filter 49 is fixedly installed on the inner annular side of the limit ring 491. The filter 49 is located above the dust suction pipe 47. The dust suction pipe 47 is located on one side of the mesh tube 481. The filter 49 blocks dust while ensuring normal discharge of air. The dust suction pipe 47 is used to perform dust suction operations at the mesh tube 481, so that the dust generated during the grinding and polishing process can be sucked into the dust hood 44 and the vertical pipe 45 under the action of the dust suction fan 471 and filtered and collected through the filter 49, effectively purifying the processing environment and reducing the harm of dust to equipment and operators.
