Description

Technical Field

[0001] This application belongs to the field of glass eyeglass manufacturing technology, specifically relating to a molding and processing device for VR glass eyeglasses. Background Technology

[0002] With the rapid development of virtual reality (VR) technology, VR glasses, as a core interactive device, directly determine the immersive experience of users through their optical performance and structural precision. The glass lenses used in the glasses, as key optical components, are of paramount importance in terms of their processing quality.

[0003] Currently, the processing of VR glass glasses lenses in the industry still largely relies on traditional cold processing technology, which is based on computer numerical control (CNC) machining and subsequent polishing.

[0004] Specifically, the initial step in traditional cold working processes is CNC machining: first, a glass block blank is fixed on the CNC machine tool, and then a preset CNC program drives the cutting tool to cut the blank, sequentially carving the inner and outer contours of the lens. During this process, the rigid contact between the cutting tool and the glass blank inevitably leaves regular or irregular tool marks on the inner and outer surfaces of the lens. These tool marks not only affect the surface roughness of the lens but also directly interfere with the subsequent transmission and refraction of optical signals, thus requiring a subsequent polishing process. Polishing, as a crucial follow-up step in traditional cold working processes, aims to remove the tool marks remaining from CNC machining, reduce the surface roughness of the lens, and improve optical transmittance.

[0005] However, existing polishing processes mostly rely on semi-automatic equipment or manual operation, using polishing tools and polishing fluid to grind the lens surface. Because VR glass lenses typically have complex aspherical curved surface structures, it is difficult to achieve perfect fit between the polishing tool and the lens surface during polishing. This necessitates frequent adjustments to polishing parameters and angles, resulting in extremely low polishing efficiency, which in turn reduces overall processing efficiency and severely restricts mass production progress. Utility Model Content To address the shortcomings of the prior art, this application provides a molding and processing device for VR glass glasses. Through the design of the upper mold mechanism and the lower mold mechanism, the planar lens can be placed in the molding cavity and directly pressed into shape, eliminating the need for the traditional cold processing method of CNC + polishing. This avoids the frequent adjustment of polishing parameters and angles required for polishing, effectively improving the efficiency of AR glass glasses molding and making it suitable for mass production.

[0006] The technical effects to be achieved in this application are realized through the following aspects: This application provides a molding and processing apparatus for VR glass glasses, including an upper mold mechanism and a lower mold mechanism arranged opposite to each other; The upper mold mechanism includes an upper mold component and a first heating component, the upper end of which is connected to the first heating component; The lower mold mechanism includes a lower mold component and a second heating component, with the lower end of the lower mold component connected to the second heating component; A molding cavity is formed between the lower mold component and the upper mold component, and the molding cavity is used to press the planar lens into VR glass glasses.

[0007] In some implementations, the upper mold mechanism further includes a heating element, which is disposed between the upper mold component and the first heating component, and is built into the upper mold component at a position corresponding to the middle of the molding cavity; The heating element is used to heat the central part of the VR glass glasses located in the molding cavity, so that the temperature of the central part of the VR glass glasses is higher than that of the edge part of the VR glass glasses.

[0008] In some implementations, the lower mold component includes a lower mold substrate and a first amorphous diamond film layer, the first amorphous diamond film layer covering the surface of the lower mold substrate; the lower end of the lower mold substrate is connected to the second heating component.

[0009] In some implementations, the lower mold substrate is a silicon carbide ceramic lower mold substrate.

[0010] In some implementations, the lower mold substrate further includes a first graphene layer, which covers the surface of the first amorphous diamond film layer.

[0011] In some implementations, the lower mold base is provided with multiple microporous air channels corresponding to the molding cavity; The lower mold component also includes an adsorption tube, which passes through the second heating component and is connected to the microporous air channel.

[0012] In some implementations, an airflow cavity is provided between the lower mold base and the second heating component, and the airflow cavity is provided corresponding to the adsorption tube.

[0013] In some implementations, both the second heating element and the first heating element include a connecting portion and a plurality of heating tubes, with the plurality of heating tubes evenly spaced and built into the connecting portion.

[0014] In some implementations, the upper mold component includes an upper mold substrate and a second amorphous diamond film layer, the second amorphous diamond film layer covering the pressing surface of the upper mold substrate; the upper end of the upper mold substrate is connected to the first heating component.

[0015] In some implementations, the upper mold component further includes a second graphene layer that covers the surface of the second amorphous diamond film layer.

[0016] In summary, this application has at least the following advantages: The VR glass glasses molding and processing apparatus provided in this application, through the design of an upper mold mechanism and a lower mold mechanism, directly places a planar lens into a molding groove. Then, a first heating element and a second heating element are activated to heat the upper mold mechanism and the lower mold mechanism, respectively. The upper mold mechanism and the lower mold mechanism are then combined to press the planar lens together to form AR glass glasses. After the AR glass glasses are formed, the upper mold mechanism and the lower mold mechanism are separated, and the formed AR glass glasses are demolded, thus completing the production of AR glass glasses. The entire process eliminates the need for traditional cold processing methods such as CNC machining and polishing, avoiding frequent adjustments to polishing parameters and angles, effectively improving the efficiency of AR glass glasses molding, and making it suitable for mass production.

[0017] In addition, the VR glass glasses are uniformly pressed and molded using the molding and processing device, which ensures the consistency of the VR glass glasses products, eliminates deviations caused by manual operation, and ensures the accuracy of the molding curvature of the VR glass glasses.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0028] Example 1: Please see the appendix Figure 1 The VR glass glasses forming and processing apparatus of this application includes an upper mold mechanism 1 and a lower mold mechanism 2. The upper mold mechanism 1 includes an upper mold component 11 and a first heating component 13, with the upper end of the upper mold component 11 connected to the first heating component 13; the lower mold mechanism 2 includes a lower mold component 21 and a second heating component 22, with the lower end of the lower mold component 21 connected to the second heating component 22; a forming cavity is formed between the lower mold component 21 and the upper mold component 11, and the forming cavity is used to press a planar lens into VR glass glasses.

[0029] During the processing, the first heating element 13 and the second heating element 22 receive signals from the control system and start heating according to the preset temperature parameters, converting electrical energy into heat energy. The heat is transferred to the upper mold component 11 and the lower mold component 21 through the first heating element 13 and the second heating element 22, thereby achieving overall temperature uniformity and ensuring the processing and forming quality of VR glass glasses.

[0030] In this embodiment, the VR glass glasses forming and processing device, through the design of the upper mold mechanism 1 and the lower mold mechanism 2, places the planar lens directly into the forming groove. Then, the first heating component 13 and the second heating component 22 are activated to heat the upper mold component 11 and the lower mold component 21 respectively. The upper mold component 11 and the lower mold component 21 are then combined to press the planar lens together to form AR glass glasses. After the AR glass glasses are formed, the upper mold component 11 and the lower mold component 21 are pulled apart, and the formed AR glass glasses are demolded, thereby completing the production of AR glass glasses.

[0031] With the above technical solution, the entire process does not require the traditional cold processing method of CNC + polishing, avoiding frequent adjustments to polishing parameters and angles required for polishing, effectively improving the efficiency of AR glass glasses molding, and making it suitable for mass production.

[0032] In addition, the VR glass glasses are uniformly pressed and molded using the molding and processing device, which ensures the consistency of the VR glass glasses products, eliminates deviations caused by manual operation, and ensures the accuracy of the molding curvature of the VR glass glasses.

[0033] In some embodiments, please refer to the appendix. Figure 2 The upper mold mechanism 1 also includes a heating element 12, which is disposed between the upper mold component 11 and the first heating element 13, and is built into the upper mold component 11 at the middle position of the molding cavity; the heating element 12 is used to heat the middle position of the VR glass glasses in the molding cavity so that the temperature of the middle position of the VR glass glasses is higher than that of the edge part of the VR glass glasses.

[0034] Preferably, the heating element 12 is in the shape of an elongated arc, and its heat dissipation range can cover about 60% of the area of ​​the VR glass glasses. Specifically, the heating element 12 is an electromagnetic induction heating element 12.

[0035] In this embodiment, the VR glass glasses molding and processing apparatus first places the flat lens in the lower mold component 21 and moves it to a hot bending furnace. The flat lens is preheated using infrared heat radiation from an infrared tube on one side of the hot bending furnace. Then, in the hot bending furnace, an inert gas is passed through, and the upper mold component 11 and the lower mold component 21 are combined, pressing the flat lens into the same shape as the molding cavity, achieving heat shaping. Simultaneously, the heating element 12 in the upper mold component 11 heats the center of the lens located in the molding cavity, ensuring that the temperature at the center is higher than the temperature at the edge of the lens, compensating for the difference in cooling shrinkage. The lens is then subjected to gradient cooling to below 200°C. After cooling is complete, the lens is demolded, and the VR glass glasses are manufactured.

[0036] Through the above technical solution, since the heating element 12 heats the center of the lens, the temperature at the center is 10-15°C higher than the temperature at the edge. If the cooling endpoint is both room temperature (25°C), and the temperature at the center is 10°C higher than the edge (i.e., the edge temperature is 200°C and the center temperature is 210°C), then the actual temperature drop at the center is 210°C - 25°C = 185°C, resulting in a shrinkage of approximately 0.076mm. This demonstrates that the actual temperature drop at the center is significantly increased, leading to a correspondingly larger shrinkage. Conversely, the actual temperature drop at the edge is 200°C - 25°C = 175°C. The shrinkage is approximately 0.071mm. Since the lens edge is not heated, it maintains a normal cooling rate, ensuring that the actual cooling amplitude and shrinkage remain largely unchanged. Meanwhile, the increased shrinkage at the center of the lens fills the original shrinkage gap, catching up with the shrinkage at the lens edge. The difference in shrinkage between the two is reduced to less than 0.005mm, effectively minimizing the difference and bringing the shrinkage at the center and edge of the lens into balance. This is far below the critical difference of 0.008mm that causes warping, achieving synchronized shrinkage. This significantly reduces internal thermal stress, prevents lens warping, effectively improves assembly yield, and ensures excellent optical performance of the lens.

[0037] Example 2: The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 3 In this embodiment, the lower mold component 21 includes a lower mold base 211 and a first amorphous diamond film layer 212, which covers the surface of the lower mold base 211. The lower end of the lower mold base 211 is connected to the second heating component 22. Preferably, the thickness of the first amorphous diamond film layer 212 is 200 nm, and the hardness is HV≥8000. Using the first amorphous diamond film layer 212 can extend the life of the mold, allowing the lower mold base 211 to be reused up to 8000 times, nearly doubling its lifespan, effectively improving the durability of the lower mold base 211.

[0038] In some embodiments, the lower mold substrate 211 is a silicon carbide ceramic lower mold substrate 211. Compared with other mold materials used in glass molding, the silicon carbide ceramic lower substrate has higher hardness, is more wear-resistant, pressure-resistant, and scratch-resistant, avoiding scratches on the mold, glass, and dents during the pressing process. Its coefficient of expansion is also lower, resulting in more stable product dimensions.

[0039] In some embodiments, the lower mold substrate 211 further includes a first graphene layer 213, which covers the surface of the first amorphous diamond film layer 212. Preferably, the thickness of the first graphene layer 213 is 10 nm. Specifically, the first graphene layer 213 is formed by dispersing graphene powder in a water or alcohol solvent with added binder, uniformly spraying the slurry in multiple layers onto the cleaned mold surface using a spray gun, and then heating and curing at 40°C to evaporate the solvent and crosslink the binder to form a coating. Preferably, six layers are sprayed. This configuration effectively reduces the coefficient of friction (μ < 0.1), avoids adhesion, effectively improves the demolding success rate, ensures demolding quality, and ensures that the surface roughness Ra of the lens is < 1 nm.

[0040] In some embodiments, the lower mold base 211 is provided with a plurality of microporous air channels corresponding to the molding cavity; the lower mold component 21 also includes an adsorption tube 214, which passes through the second heating component 22 and is connected to the microporous air channels. Specifically, the other end of the adsorption tube 214 is connected to a vacuum adsorption system, so that negative pressure is applied through the adsorption tube 214 and the microporous air channels to adsorb the lens. Preferably, the negative pressure is 0.2–0.3 MPa, so that the lens fits tightly against the mold during the molding stage, ensuring the stability of the lens processing.

[0041] The microporous air channels consist of 50μm diameter micropores distributed on the curved surface of the mold. Specifically, the formation process of the microporous air channels is as follows: During the dry pressing preparation of the silicon carbide ceramic lower mold substrate 211, a certain amount of 100μm particle size carbon powder and starch, i.e., pore-forming agents, are mixed in. These are burned and decomposed during the sintering process at 700℃-800℃, leaving approximately 50μm pores in the dense silicon carbide ceramic lower mold substrate 211. This results in 50μm micropores distributed on the mold surface, which are connected to the adsorption tubes 214 and 216, thereby achieving a negative pressure function for the lens through the microporous air channels.

[0042] In some embodiments, an airflow cavity 215 is provided between the lower mold base 211 and the second heating element 22, and the airflow cavity 215 is arranged corresponding to the adsorption tube 214. This arrangement allows the large-area negative pressure adsorption of the airflow cavity 215 to distribute the adsorption force evenly on the workpiece surface, ensuring stability during the lens processing.

[0043] In some embodiments, see Figure 4 Both the second heating element 22 and the first heating element 13 include a connecting portion 131 and multiple heating tubes 132, which are evenly spaced and built into the connecting portion 131. With this configuration, the heating tubes 132 can receive signals from the control system and start heating according to preset temperature parameters, converting electrical energy into heat energy. The heat is transferred through the connecting portion 131 to the upper mold component 11 and the lower mold component 21, thereby achieving overall temperature uniformity and ensuring the processing and molding quality of the VR glass glasses.

[0044] In some embodiments, the upper mold component 11 includes an upper mold substrate 111, a second amorphous diamond film layer, and a second graphene layer. The second amorphous diamond film layer covers the pressing surface of the upper mold substrate 111. The upper end of the upper mold substrate 111 is connected to the first heating component 13. The second graphene layer covers the surface of the second amorphous diamond film layer. Preferably, the thickness of the second amorphous diamond film layer is 200 nm, and the hardness is HV≥8000. Using the second amorphous diamond film layer can extend the life of the mold, and the upper mold substrate 111 can be reused up to 8000 times, effectively improving the durability of the upper mold substrate 111.

[0045] Preferably, the thickness of the second graphene layer is 10 nm. Specifically, the second graphene layer is formed by dispersing graphene powder in a water- or alcohol-based solvent with a binder, uniformly spraying the slurry in multiple layers onto the cleaned mold surface using a spray gun, and then heating and curing at 40°C to evaporate the solvent and cross-link the binder to form a coating. Preferably, six layers are sprayed. This setup effectively reduces the coefficient of friction (μ < 0.1), avoids adhesion, effectively improves the demolding success rate, ensures demolding quality, and ensures that the lens surface roughness Ra < 1 nm.

[0046] Example 3: This embodiment is based on the above embodiment; please refer to [link / reference]. Figure 5 A method for molding VR glass glasses is provided, including the following processing steps: S1: Manufacturing of planar lenses: The optical glass substrate and the functional film are pre-pressed together in a vacuum environment using a bonding machine to form a planar lens; after the optical glass substrate and the functional film are bonded together, the excess edges of the functional film are removed using a laser. S2: VR Glass Glass Forming: The initial lens is placed into the forming cavity of the VR glass glass forming processing device described above, and the VR glass glasses are shaped using a three-stage temperature control process.

[0047] The VR glass glasses forming method in this embodiment first laminates an optical glass substrate with a functional film to form a planar lens. Then, the multilayer material of the laminated optical glass substrate and functional film is simultaneously formed, solving the problems of bubbles and wrinkles that occur when laminating polarizing films in traditional hot bending processes. This process achieves an interlayer peel strength ≥15N / cm, with no bubbles or wrinkles, effectively improving forming quality and increasing production yield. It should be further noted that the pressing process conditions for the optical glass substrate and functional film are: a gas pressure of 10Pa to ensure that most of the air is extracted, eliminating the possibility of gas expansion and bubble formation; temperature control at 60℃-70℃ to reduce the viscosity of the adhesive and increase its fluidity and uniformity; pressure of 0.1MPa-0.2MPa, applied evenly and parallelly to avoid glass breakage; and heat and pressure holding for 12 minutes.

[0048] In some embodiments, see Figure 6 In S1, the pre-compression treatment is achieved using dynamic pressure control, specifically as follows: S11: Initial pressure is used to initially bond the optical glass substrate and the functional film; preferably, the initial pressure is 0.5 MPa; S12: The initial pressure is increased to the molding pressure in a stepped manner, and each stage is maintained for 30 seconds; the molding pressure is specifically 8 MPa. S13: Reduce the molding pressure to the holding pressure, enter the holding pressure stage, and maintain the holding pressure for 60 seconds; the holding pressure is specifically 3 MPa.

[0049] With the above settings, a low-pressure bonding method is first used in S11 to ensure uniform contact and natural alignment between the optical glass substrate and the functional film surfaces. This avoids film displacement or wrinkling caused by the instantaneous impact of high pressure, ensuring the positional accuracy of subsequent bonding. Furthermore, during low-pressure bonding, air between the optical glass substrate and the functional film can slowly escape along the edges, preventing direct high pressure from trapping air at the interface and forming air bubbles that cannot escape, thus ensuring bonding quality.

[0050] The stepped pressurization method used in S12 allows pressure to be evenly distributed across the entire bonding surface, enabling the optical glass substrate and functional film to deform synchronously and bond uniformly, reducing structural damage caused by localized stress concentration. Furthermore, the stepped pressurization provides time for air to escape in stages; with each pressure increase, the interface gaps further shrink, residual air is gradually expelled, ultimately achieving bubble-free bonding and effectively ensuring bonding quality.

[0051] Reducing the molding pressure from 8 MPa to the holding pressure of 3 MPa in S13 allows the material to rebound slowly, gradually releasing internal stress and preventing film peeling or glass cracking due to stress release during subsequent processes or product use. The 60-second holding pressure stage allows for full contact between interface molecules and thorough leveling and curing of the adhesive, further strengthening the bond between the optical glass substrate and the functional film, and improving the long-term reliability of the product.

[0052] In some embodiments, see Figure 7 In S2, the three-stage temperature control processing method is as follows: S21: During the preheating stage, the flat lens is placed in the lower mold component 21 at room temperature and enters the hot bending furnace along with the forming processing device. The flat lens is preheated by receiving thermal radiation from an infrared tube on one side of the hot bending furnace. Preferably, the preheating temperature can be 300℃–500℃. S22: In the forming stage, inert gas is introduced into the hot bending furnace, and the lens in the forming cavity is locally heated by the heating element 12, so that the temperature of the center position of the lens is higher than the temperature of the edge position of the lens than the set temperature; preferably, the inert gas can be nitrogen gas with a flow rate of 500L / min and a temperature of 40°C; the set temperature is any value of 10°C–15°C.

[0053] S23: In the slow cooling stage, a certain cooling rate is adopted to gradually cool the forming and processing device to below 200℃; preferably, the cooling rate is ≤5℃ / s; the gradient cooling can be divided into 7 gradient temperature control zones, and the temperature set by the machine in each temperature control zone decreases by 80℃.

[0054] Specifically, in S21, the preheating range of 300℃–500℃ can be uniformly heated by infrared tube thermal radiation. Infrared heating is non-contact and the temperature transfer is gradual, avoiding local hot spots and allowing the overall temperature of the lens to rise slowly. This allows the temperature of each area of ​​the lens to rise synchronously, avoiding pre-deformation caused by local thermal expansion before and after, effectively reducing the temperature difference between the inner and outer layers, releasing some of the initial thermal stress in advance, and reducing pressure for subsequent high-temperature molding.

[0055] In S22, nitrogen gas at 40℃ is introduced at a high flow rate of 500L / min, rapidly displacing the air in the forming cavity and reducing the oxygen concentration to below 0.1%, creating an inert protective atmosphere that completely blocks contact between the glass and oxygen. This ensures the lens surface maintains its original high transmittance and high gloss even at high temperatures. Furthermore, by setting the temperature to any value between 10℃ and 15℃, the temperature difference within this range can compensate for the central shrinkage gap, ensuring consistent shrinkage between the center and edges of the lens. Simultaneously, the 10℃–15℃ range prevents secondary deformation of the lens. Since the softening point of VR glass is ≥550℃, and the initial temperature of the lens during the cooling stage is only around 200℃, even if the temperature in the central area rises to 210-215℃ after heating, it remains far below the softening point, preventing secondary softening and detachment from the mold. Additionally, the hot bending process is completely cured below 200℃, preventing adhesion or deformation during heating and ensuring forming accuracy.

[0056] In S23, a low cooling rate of ≤5℃ / s allows the inner and outer layers of the lens to cool down slowly and synchronously, giving molecules sufficient time to reset and gradually release internal stress. This keeps the final residual stress within a safe range, preventing cooling cracks. Seven gradient temperature control zones ensure that in the high-temperature range, the glass still retains some plasticity, allowing for slow cooling in the first gradient zone to release most of the acute stress from the forming stage. In the medium-temperature range, the glass gradually transitions from a plastic to a brittle state, requiring subsequent gradient zones to further slow down the cooling rate and reduce new stresses caused by temperature fluctuations. In the low-temperature range, the glass is essentially hardened, allowing for a slightly faster cooling rate, but gradient control is still needed to avoid thermal stress, ensuring no new defects during the cooling process, guaranteeing dimensional consistency in mass-produced lenses, and meeting the high-precision requirements of optical assembly.

[0057] The above technical solution, through the linkage of three major stages, achieves a collaborative closed loop of preheating to lay the foundation, forming precision control, and slow cooling to ensure stability. It can be precisely executed by automated equipment to ensure consistency in mass production, and the yield rate can be improved to over 95%, achieving high-precision, high-yield, and high-reliability optical lenses.
