Description
Technical Field
The invention relates to the field of optical lenses, in particular to a processing method of an optical reflecting lens.
Background
Augmented Reality (AR) is a technology for calculating the position and angle of a camera image in real time and adding a corresponding image, and the technology aims to sleeve a virtual world on a screen in the real world and perform interaction.
In AR glasses, an optical reflection lens is an important part. When the optical reflection lens is concave semi-transparent semi-reflection (visible light transmittance >43%, polarized light reflectance >90%, transmission optical axis angle 45 ± 2 °, and curvature radius error less than 1.5%), the optical reflection lens can provide good imaging reflection without affecting the user to watch external scenery, and the user experience is more real in cooperation with an actual game scene.
The optical reflection lens generally comprises a lens substrate and an APF film, and at present, the processing method of the optical reflection lens is as follows: respectively forming the lens base material and the APF film into the shape of the optical reflection lens, attaching the APF film to the OCA film after forming, and then laminating the APF film attached with the OCA film and the lens base material in vacuum and high pressure, thereby forming the optical reflection lens. However, the optical mirror has the following problems: since the OCA adhesive film is a soft product, after vacuum high-pressure lamination, the surface flatness of the OCA adhesive film formed between the lens substrate and the APF film is poor (as shown in fig. 1), which affects the imaging quality of the optical reflective lens (as shown in fig. 2). When the optical reflection lens with poor weather resistance of the OCA adhesive film is used, the OCA adhesive film is unstable and easy to deform, and the imaging quality of the optical reflection lens is also affected.
In addition, in the existing processing technology of the optical reflection lens, the APF film is firstly fixed on the jig and is attached to the lens base material after being formed by high pressure, and the APF material can be ensured to be attached to the lens base material only by exceeding the lens base material, so that the problem of low material utilization rate exists.

step 1, adopting UV light-cured glue to be adhered between an APF film and a PMMA (acrylic) film to form a semi-finished film, wherein the UV light-cured glue forms a hard glue layer of 2-5um between the APF film and the PMMA film.
The UV light-curing glue comprises 65% of a main agent and 35% of an auxiliary agent, wherein the main agent comprises 60% of unsaturated polyester resin and 40% of styrene, and the auxiliary agent comprises 20% of maleic anhydride, 20% of propylene glycol and 40% of styrene. The hard glue layer formed by the UV light-curing glue has certain hardness and rebound resilience, so that the hard glue layer has good weather resistance and good stability, and the imaging quality of the optical reflector is further ensured.
The PMMA film has a hardness value of H-2H so as to reduce the deformation of the molded optical reflecting lens. The PMMA film may be formed using a PMMA material of Kanaeka No. 009 NCH.
And step 2, cutting the semi-finished film material obtained in the step 1 at a transmission and vibration axis angle of 45 +/-2 degrees (as shown in fig. 5).
Before cutting, the semi-finished film should be inspected by a transmission shaft to ensure the cutting accuracy, as shown in fig. 4.
And 3, carrying out hot press molding on the cut semi-finished film material, wherein the hot press temperature is 60 +/-2 ℃, the molding period is 200 +/-10S, the APF film can not be damaged due to the temperature in the hot press process, and meanwhile, the product resilience after the hot press molding is reduced by prolonging the molding period.
And 4, punching the hot-press formed semi-finished film by using a 3D punching die, wherein the punched and formed semi-finished film meets the requirement of the size of the injection mold.
And 5, placing the punched and molded semi-finished product film material into an injection mold, pouring the PMMA material into the injection mold, melting the PMMA film of the semi-finished product film material by utilizing injection molding high temperature, and combining the PMMA film with the PMMA material to form the optical reflection lens with the curvature radius of 127 +/-2 mm and the thickness of 2.0-2.2mm, wherein the PMMA film of the semi-finished product film material is combined with the poured PMMA material to form the lens base material of the optical reflection lens.
The curvature radius of the optical reflection lens is consistent with that of the injection mold, so that the curvature radius of the optical reflection lens is 127 +/-2 mm, and the curvature radius of the injection mold is only required to be set to be 127 +/-2 mm.
The flowability of the poured PMMA material is 5.5g/10min, preferably the PMMA material with the ASAHIKASEI mark of 80NH is matched with the fan-shaped pouring design of the side surface of the hot runner of the large water gap of the injection mould, so that the stress of injection moulding is reduced.
And 6, placing the injection molded product in a constant-temperature and constant-humidity environment of 40 +/-2 ℃ multiplied by 60 +/-5% RH for 16H (hours) for stress relief treatment, eliminating injection residual stress, reducing variables generated after shape cutting and ensuring that the curvature radius error of the product is less than 1.5%.
The key point of the invention is that UV light-cured glue is adopted to attach an APF film and a PMMA film to form a semi-finished film material, then the semi-finished film material is subjected to cutting, hot pressing and punching, then is subjected to injection molding with a lens base material, and then is subjected to stress relief treatment to form the optical reflection lens. In the processing process of the optical reflection lens, the UV light-cured glue can form a hard glue layer between the APF film and the lens substrate, and compared with a soft glue layer, the hard glue layer has high surface flatness and high stability and is not easy to deform, so that the imaging quality of the optical reflection lens is ensured (as shown in figure 6). In addition, in the processing process of the optical reflection lens, the semi-finished product film material containing the APF film and the lens base material form the optical reflection lens in an injection molding mode, and the AFP film with the size smaller than that of the lens base material can also ensure the bonding quality between the AFP film and the lens base material, so that the material utilization rate of the APF film is improved (by 20-30% compared with the prior art), and the material waste is reduced.
