Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] With the development of hardware such as optical display units, computing units, and sensing units, as well as the continuous enrichment of the software ecosystem, AR (Augmented Reality) / VR (Virtual Reality) technology has greatly improved the interactivity and immersion brought to users, and has shown broad application prospects in the fields of industry, medical care, education, security, leisure and entertainment. For AR / VR products, their optical imaging effects will directly affect the user experience. As users' requirements for the imaging clarity of AR / VR products gradually increase, existing AR / VR products are difficult to meet users' requirements for the imaging clarity of AR / VR products.

[0054] Taking the workpiece to be processed as an AR / VR lens as an example, the applicant has found through careful research that the surface roughness of the AR / VR lens will affect the optical imaging effect of the AR / VR. A high roughness will lead to serious light scattering, which in turn affects the clarity and realism of the AR / VR product. At present, the industry generally adopts the traditional milling mode to process the lens surface, and the roughness of the processed lens surface is generally around 40 nanometers. This roughness restricts the improvement of the clarity of the AR / VR product. The applicant has further found through careful research that since traditional milling is not a continuous cutting process, when faced with the problem of how to improve the surface roughness of the lens, technical personnel in this field generally adopt changing the tool material and using high-precision single crystal lathes for processing. However, on the one hand, the processing method using this method is costly, and on the other hand, this processing method still cannot meet the requirements of effectively reducing the surface roughness of the lens for lenses with larger curvatures.

[0055] In view of this, the present invention proposes a lens processing method, aiming to solve the technical problem of how to improve the imaging clarity of AR / VR products.

[0056] See also Figure 1 , Figure 1 The present invention provides a flowchart of a first embodiment of a lens processing method. In one embodiment of the present invention, the lens processing method is applied to a lens processing device, wherein the lens processing device comprises a tool mechanism, a driving mechanism and a tray, wherein the driving mechanism is in transmission connection with the tool mechanism so that the driving mechanism can drive the tool mechanism to move, and the tray is used to place a workpiece to be processed, wherein the workpiece to be processed is provided with a surface to be processed; the lens processing method comprises the following steps:

[0057] S100, obtaining processing information of the surface to be processed and tool motion path information;

[0058] For different surfaces to be processed, corresponding processing information and tool motion path information are matched, so that the corresponding processing surfaces can be processed according to the processing information and tool motion path information in the future to adapt to the processing of different processing surfaces and provide a certain guarantee for the processing effect of each surface to be processed.

[0059] It should be noted that the processing information of the surface to be processed and the tool motion path information can be obtained by scanning the code, that is, each workpiece to be processed has a corresponding code, and the processing information and tool motion path information of each surface to be processed on the workpiece to be processed can be obtained by scanning the code; the processing information and tool motion path information of each surface to be processed can also be obtained through pre-set parameter information; therefore, the method of obtaining the processing information and tool motion path information of the surface to be processed is not limited here.

[0060] S200, controlling the driving mechanism to drive the tool mechanism to contact the surface to be processed according to the processing information and the tool motion path information;

[0061] The driving mechanism drives the tool mechanism to contact the surface to be processed according to preset parameters based on the processing information, so that the tool can contact the surface to be processed according to a specific angle and pressure, thereby providing a certain guarantee for the cutting effect of the surface to be processed; the driving mechanism moves to the starting position of the cutting processing path according to the tool motion path information, so as to subsequently move according to the tool motion path provided by the tool motion path information.

[0062] S300, controlling the driving mechanism to drive the tool mechanism to scrape the surface to be processed according to the tool motion path information.

[0063] The driving mechanism drives the tool mechanism to scrape the surface to be processed according to the preset path according to the tool movement path information, thereby effectively reducing the surface roughness of the workpiece to be processed.

[0064] The technical solution of the present invention obtains the processing information of the surface to be processed and the tool movement path information, controls the driving mechanism to drive the tool mechanism to contact the surface to be processed according to the processing information, and then controls the driving mechanism to drive the tool mechanism to scrape the surface to be processed according to the preset path according to the tool movement path information, wherein scraping and milling are two different processing techniques, scraping is to scrape off trace substances on the surface of the processed workpiece, while milling is to cut the surface of the workpiece by a rotating milling cutter; in terms of the movement path, taking the square surface to be processed as an example, the current method of using the milling process for mirror processing is: the tool movement path of the milling processing is extended along the length or width direction of the square surface to be processed, taking the length direction as an example, after the rotating milling cutter moves from one end of the surface to be processed to the other end, the milling cutter stops rotating, and then rotates in the opposite direction, and then mills along another path extending in the length direction. The inventor has found through research that the process of stopping and rotating the tool in the milling process is not only time-consuming, but also has a great impact on the roughness of the workpiece surface; and the present solution uses scraping to process the lens. Compared with the milling cutter, the scraper does not rely on rotation to remove the surface to be processed. The scraper does not scrape the surface of the workpiece, but scrapes off the surface material of the workpiece. Since the scraper does not need to rely on rotation to remove the processing surface, the scraper does not involve the process of rotation and stopping. Taking the square surface to be processed as an example, the scraper is used to gradually move inward along the outer periphery of the square surface to be processed, so as to complete the removal of the entire surface to be processed. The entire processing movement process of the scraper is continuous. Combined with the processing method of the scraper itself that is different from that of the milling cutter, the roughness of the processed lens can be reduced to about 7 nanometers. The improvement of surface quality makes the lens have higher gloss and precision, thereby providing a guarantee for high-quality optical imaging; the lens obtained by the lens processing method has higher flatness and lower roughness, thereby effectively reducing the scattering and reflection of light, making the transmittance and reflectivity of light more reasonable, and the AR image is brighter and clearer, which enhances the user's perception and interactive experience of virtual information; processing the lens by the lens processing method greatly improves the optical performance of the lens, thereby improving the clarity and high realism of the image displayed by the AR / VR product, so that the user can get a more realistic visual experience when using the VR / AR device. It should be noted that, for the same roughness processing requirements, compared with the use of high-precision single crystal lathe processing, this solution can meet the processing requirements with lower-cost tools in the selection of tools, so the processing cost is lower, and due to the continuity of the processing process of this solution combined with the scraping processing method, the efficiency is also higher, thereby effectively improving the quality and competitiveness of the product. It should be noted that the above lens processing method can also be applied to the processing of lenses with larger curvatures, and can complete the processing of lenses with lower surface roughness compared with high-precision single crystal lathe processing.

[0065] In one embodiment, the driving mechanism includes a tool driving assembly, the tool driving assembly is in transmission connection with the tool mechanism, the tool driving assembly can drive the tool mechanism to move, the processing information includes tool pressure information, and the step of S200 includes:

[0066] S210, controlling the tool driving assembly to drive the tool mechanism to contact the workpiece to be processed at a preset pressure according to the pressure information and the tool motion path information.

[0067] The machining surfaces of different workpieces and the different machining surfaces of the same workpiece all have corresponding machining requirements, and the pressure of the tool on the machining surface is one of the important factors affecting the cutting effect. The preset pressure size is obtained through the pressure information, so that the tool drive assembly can drive the tool mechanism to contact the machining surface with the preset pressure according to the pressure information, thereby providing a certain guarantee for the cutting effect.

[0068] See also Figure 2 , Figure 2 The flowchart of the second embodiment of the lens processing method provided by the present invention is as follows. In one embodiment, the processing information further includes tool angle information, the driving mechanism further includes an adjustment component, the tool driving component can drive the tool mechanism to move along the Y axis and the Z axis, the adjustment component is in transmission connection with the tray, and the adjustment component can drive the workpiece to be processed to move along the X axis, rotate around the X axis, and rotate around the Z axis through the tray to change the position and angle between the tool mechanism and the surface to be processed; the step of S210 includes:

[0069] S211, controlling the tool driving component to drive the tool mechanism to contact the workpiece to be processed at a preset pressure according to the pressure information and the tool motion path information, and at the same time controlling the adjustment component to drive the workpiece to be processed to move to the tool mechanism to contact the surface to be processed at a preset angle according to the tool angle information and the tool motion path information.

[0070] The angle at which the tool contacts the surface to be processed is also one of the important factors that affect the cutting effect. The preset contact angle is obtained through the tool angle information. The adjustment component can drive the surface to be processed to move and rotate to adjust the contact angle between the surface to be processed and the tool mechanism, so that the tool mechanism can contact the surface to be processed at the preset contact angle, thereby providing a certain guarantee for the cutting effect. It should be noted that the tool drive component and the adjustment component can make the tool mechanism contact the starting point of the preset moving path of the tool located on the surface to be processed according to the tool movement path information; the tool drive component and the adjustment component can also make the tool mechanism contact any point on the preset moving path of the tool located on the surface to be processed according to the tool movement path information. Taking the annular surface to be processed as an example, the tool mechanism and the surface to be processed can be any point on the preset moving path or the starting point of the preset moving path. Whether it starts moving from the starting point or from any point of the preset moving path, the tool mechanism will eventually complete the complete preset moving path, so there is no clear requirement for the position of the contact point. It should also be noted that the contact point between the tool mechanism and the surface to be processed needs to fall on the preset moving path of the tool.

[0071] In one embodiment, the tool mechanism includes a mounting frame and a tool body, the tool body is detachably connected to the mounting frame, the mounting frame is connected to the tool drive assembly, the processing information includes tool shape information and tool material information; the lens processing equipment also includes a tool changing mechanism; after step S100 and before step S200, the following steps are included:

[0072] S110, controlling the tool changing mechanism to select the tool body according to the tool shape information and the tool material information;

[0073] S120, controlling the tool changing mechanism to install the tool body on the mounting frame.

[0074] The lens processing method of this scheme is a processing method that uses a specially designed tool body to perform fine cutting actions on the surface of the workpiece to be processed. Therefore, the selection and design of the tool body are crucial. The tool body used for processing must have a special geometric shape and material, so as to provide a certain guarantee for the tool body to be able to perform efficient and accurate cutting on the surface to be processed. Different surfaces to be processed or the surfaces to be processed of different workpieces to be processed will have different requirements for the tool body. Therefore, it is necessary to select a tool body that matches the surface to be processed according to the tool shape information and tool material information corresponding to the current processing surface. After the tool body is selected by the tool changing mechanism, the tool changing mechanism will install the tool body to the mounting frame, and the tool body will be fixed by the mounting frame to ensure that the relative position and angle between the tool body and the mounting frame are relatively accurate. It should be noted that the selection and installation of the tool body can also be done manually.

[0075] See also Figure 3 , Figure 3 This is a flow chart of a third embodiment of the lens processing method provided by the present invention. In one implementation, the processing information includes scraping depth information, and the step S300 includes:

[0076] S301, controlling the driving mechanism to drive the tool mechanism to scrape the surface to be processed, and controlling the driving mechanism in real time to adjust the scraping depth of the tool mechanism according to the scraping depth information.

[0077] The scraping depth is also one of the key factors affecting the surface flatness and low roughness of the workpiece to be processed. The driving mechanism adjusts the scraping depth of the tool mechanism according to the scraping depth information to provide effective guarantee for the flatness and low roughness of the processed surface.

[0078] See also Figure 4 , Figure 4 This is a flow chart of a fourth embodiment of the lens processing method provided by the present invention. In one implementation, the processing information includes feed speed information, and the step S300 includes:

[0079] S302, controlling the driving mechanism to drive the tool mechanism to scrape the surface to be processed, and controlling the driving mechanism in real time to adjust the feed speed of the tool mechanism according to the feed speed information.

[0080] Among them, the feed speed of the tool body relative to the processing surface is also one of the key factors affecting the surface flatness and low roughness of the workpiece to be processed. The driving mechanism adjusts the feed speed of the tool mechanism relative to the processing surface according to the feed speed information to provide effective guarantee for the flatness and low roughness of the processing surface. It should be noted that the scraping depth and economic speed can be adjusted in real time during the scraping process. It should also be noted that there are differences in the scraping depth information and feed speed information of the processing surfaces of different processing surfaces and different workpieces to be processed. The processing surface is processed by the scraping depth information and feed speed information adapted to the processing surface, so that the removal of each processing surface can basically meet the requirements.

[0081] In one embodiment, the step of obtaining tool motion path information includes:

[0082] The tool motion path information is obtained according to the shape information and size information of the workpiece to be processed.

[0083] The moving path of the tool body is carefully planned. When planning the moving path of the tool body, it is necessary to fully consider the different shapes and sizes of the workpiece to be processed, so as to ensure that the tool can accurately reach each part that needs to be processed; therefore, it is necessary to obtain the tool movement path information through the shape information and size information of the workpiece to be processed. It should be noted that the movement trajectory of the tool body can be simulated and optimized by using computer-aided design and manufacturing (CAD (Computer Aided Design, Computer Aided Design) / CAM (Computer aided manufacturing, Computer Aided Manufacturing)) technology.

[0084] See also Figure 5 , Figure 5 This is a flow chart of a fifth embodiment of the lens processing method provided by the present invention. In one embodiment, the lens processing device further includes a detection mechanism and a control mechanism. The detection mechanism includes a tool detection member, which is communicatively connected to the control mechanism. The tool detection member is used to detect the tool mechanism to obtain tool force information of the tool mechanism. The step of S300 includes:

[0085] S310, controlling the driving mechanism to drive the tool mechanism to scrape the surface to be processed, and controlling the tool detection component to obtain the tool force information in real time, and feeding back the tool force information to the control mechanism in real time.

[0086] The tool detection part is set to obtain the tool force information in real time, and the tool force information is fed back to the control mechanism so that the control mechanism can obtain the force condition of the tool body, thereby better monitoring the processing process.

[0087] See also Figure 6 , Figure 6 This is a flow chart of a sixth embodiment of the lens processing method provided by the present invention. In one embodiment, the lens processing device further includes a detection mechanism and a control mechanism. The detection mechanism includes a temperature detection element. The temperature detection element is communicatively connected with the control mechanism. The temperature detection element is used to obtain temperature information. The temperature information includes tool temperature information and environmental processing environment temperature information. The step of S300 includes:

[0088] S320, controlling the driving mechanism to drive the tool mechanism to scrape the surface to be processed, and controlling the temperature detection component to obtain the tool temperature information and the processing environment temperature information in real time, and feeding back the tool temperature information and the processing environment temperature information to the control mechanism in real time.

[0089] By setting a temperature detection component, the temperature of the tool body, i.e., the tool temperature information, and the ambient temperature around the tool body, i.e., the processing environment temperature information, can be obtained in real time, so that the control mechanism can obtain the tool temperature information and the processing environment temperature information in real time, thereby better monitoring the processing process.

[0090] In one embodiment, the lens processing equipment further comprises a temperature control mechanism, the temperature control mechanism is communicatively connected to the control mechanism, and the temperature control mechanism is used to adjust the temperature of the tool mechanism and the ambient temperature around the tool mechanism; and the step of feeding back the tool temperature information and the processing environment temperature information to the control mechanism in real time comprises:

[0091] The tool temperature information and the processing environment temperature information are fed back to the control mechanism in real time, and the control mechanism controls the temperature control mechanism to adjust the temperature of the tool mechanism and the ambient temperature around the tool mechanism in real time according to the tool temperature information and the processing environment temperature information.

[0092] The temperature of the tool body and the ambient temperature around the tool body are adjusted by the control mechanism according to the tool temperature information and the processing environment temperature information, thereby providing an effective guarantee for the stability of the processing process and the consistency of the processing quality. It should be noted that the temperature control mechanism can be used to adjust the temperature of the coolant during the processing, or it can be used to adjust the ambient temperature to affect the temperature of the tool body and the ambient temperature around the tool body.

[0093] In one embodiment, the number of the to-be-processed surfaces is multiple, the multiple to-be-processed surfaces are stacked in sequence, the to-be-processed surfaces are consistent with the number of the processing information and are arranged one-to-one, and the step of controlling the driving mechanism to drive the tool mechanism to scrape the to-be-processed surfaces includes:

[0094] Determining whether the surface to be processed is removed;

[0095] If yes, obtaining the machining information and the tool motion path information of the surface to be machined located at the outermost side of the workpiece to be machined;

[0096] Repeat the step of controlling the driving mechanism to drive the tool mechanism to contact the surface to be processed according to the processing information and the tool motion path information.

[0097] Since the same workpiece may have multiple surfaces to be processed that are stacked in sequence, and the processing requirements of different processing surfaces are different, after completing the removal of one surface to be processed, it is necessary to re-acquire the latest processing information of the surface to be processed and the tool motion path information, so that the removal of each surface to be processed can basically meet the requirements.
