[0002] With the development of technology, wearable devices are being applied to people's lives. Wearable devices include frames and lenses. Lenses are used for users to see. As optical elements, lenses need to be framed and attached before use. In the prior art, lenses include a first lens layer and a second lens layer. The surfaces of the first lens layer and the second lens layer are both attached to a rigid member and subjected to pressure from the rigid member in one direction. The first lens layer and the second lens layer bend and deform under pressure in one direction, resulting in low bending accuracy of the first lens layer and the second lens layer. Summary of the Invention

At the same time, the second lens layer is subjected to forces in different directions, and the second adsorption member flexibly adsorbs the second lens layer, improving the bending effect of the second lens layer, thereby ensuring the bending accuracy of the first lens layer and the second lens layer.

[0004] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0005] According to one aspect of the embodiments of this application, an adsorption-type frame attachment method for lenses is provided, comprising:

[0022] The fourth moving part stops moving, causing the second adsorption part to stop moving and adsorbing the second lens layer;

[0023] The second moving component continues to move, causing the second bonding platform to continue moving and bending and deforming the second lens layer.

[0055] Figure 1 A schematic flowchart of an adsorption-type frame attachment method for a lens according to an embodiment of this application is shown. This method can be applied to electronic devices, including but not limited to wearable devices such as AR (Augmented Reality), VR (Virtual Reality), and MR (Mixed Reality) electronic devices.

[0056] Please refer to Figure 1 The method for attaching the lens to the frame includes at least steps S110 to S140, which are described in detail below (the following description uses the application of this method to a wearable device as an example):

[0057] In step S110, the first bonding platform 211 and the first adsorption member 213 connect different regions in the first lens layer 214, and the second bonding platform 221 and the second adsorption member 223 connect different regions in the first lens layer 214.

[0058] In the embodiments of this application, different regions of the first lens layer 214 are connected by the first bonding platform 211 and the first adsorption member 213, respectively. At this time, the first bonding platform 211 connects the non-central region of the first lens layer 214, and the first adsorption member 213 connects the central region of the first lens layer 214, so that the first lens layer 214 is subjected to different forces in different regions, so as to facilitate the subsequent bending of the first lens layer 214.

[0059] The first bonding platform 211 is connected to a first region of the first lens layer 214 via a first elastic pad 212. This first region is a non-central region. The first elastic pad 212 elastically connects the first bonding platform 211 and the first lens layer 214 to ensure the bending accuracy and stability of the first lens layer 214. Optionally, the two sides of the first elastic pad 212 are connected to the first bonding platform 211 and the first region of the first lens layer 214.

[0060] The first adsorption member 213 passes through the first elastic pad 212 and connects to the third region in the first lens layer 214. In this case, the first adsorption member 213 acts as a vacuum suction cup, adsorbing the first lens layer 214 under negative pressure. The third region serves as the central region. The adsorption end of the first adsorption member 213 relative to the first lens layer 214 is a flexible end, applying a flexible force to the first lens layer 214 to ensure its bending and stability. Furthermore, this allows the first bonding platform 211 and the first adsorption member 213 to exert different forces on the first lens layer 214 in different regions, facilitating subsequent bending of the first lens layer 214. Optionally, the distance between the boundary of the third region and the center of the second lens layer 224 is 0-50 mm.

[0061] Meanwhile, the first bonding platform 211 is connected to the first moving member, and the first suction member 213 is connected to the third moving member. The first moving member and the third moving member are controlled independently. Before the first lens layer 214 and the second lens layer 224 are connected, the first moving member and the third moving member move at the same speed. After the first lens layer 214 and the second lens layer 224 are connected, the first moving member continues to move, while the third moving member stops moving, so as to apply a reverse force to the first lens layer 214 based on the first bonding platform 211 and the first suction member 213, thereby improving the bending accuracy of the first lens layer 214.

[0062] Relative to the second lens layer 224, different regions in the second lens layer 224 are respectively connected by the second bonding platform 221 and the second suction member 223. At this time, the second bonding platform 221 connects the non-central region of the second lens layer 224, and the second suction member 223 connects the central region of the second lens layer 224, so that the second lens layer 224 is subjected to different forces in different regions, so as to facilitate the subsequent bending of the second lens layer 224.

[0063] The second bonding platform 221 is connected to the second region of the second lens layer 224 via the second elastic pad 222. The second region is a non-central region. The second elastic pad 222 elastically connects the second bonding platform 221 and the second lens layer 224 to ensure the bending and stability of the second lens layer 224.

[0064] The second suction member 223 passes through the second elastic pad 222 and connects to the fourth region in the second lens layer 224. In this case, the second suction member 223 acts as a vacuum suction cup, adsorbing the second lens layer 224 under negative pressure. The fourth region is the central region. The adsorption end of the second suction member 223 relative to the second lens layer 224 is a flexible end, applying a flexible force to the second lens layer 224 to ensure its bending and stability. Furthermore, this allows the second bonding platform 221 and the second suction member 223 to exert different forces on the second lens layer 224 in different regions, facilitating subsequent bending of the second lens layer 224. Optionally, the distance between the boundary of the fourth region and the center of the second lens layer 224 is 0-50 mm.

[0065] Simultaneously, the second bonding platform 221 is connected to the second moving member, and the second suction member 223 is connected to the fourth moving member. The second and fourth moving members are independently controlled. Before the first lens layer 214 and the second lens layer 224 are connected, the second and fourth moving members move at the same speed. After the first lens layer 214 and the second lens layer 224 are connected, the second moving member continues to move, while the fourth moving member stops moving. This allows the second bonding platform 221 and the second suction member 223 to apply a reverse force to the second lens layer 224, so that the second lens layer 224 is subjected to different forces in different areas, thereby improving the bending effect of the second lens layer 224 in subsequent bending processes.

[0066] refer to Figure 2 In step S120, as the first bonding platform 211 and / or the second bonding platform 221 move, the first lens layer 214 and the second lens layer 224 are connected by the bonding adhesive 230. At this time, the first bonding platform 211 and the first adsorption member 213 move synchronously, and the second bonding platform 221 and the second adsorption member 223 move synchronously.

[0067] In the embodiments of this application, as the first bonding platform 211 and / or the second bonding platform 221 move, the first bonding platform 211 and the second bonding platform 221 gradually approach each other, and the first lens layer 214 and the second lens layer 224 are connected by adhesive 230. The adhesive 230 is located between the first lens layer 214 and the second lens layer 224 and connects the first lens layer 214 and the second lens layer 224. The adhesive 230 serves as a support between the first lens layer 214 and the second lens layer 224 to support the first lens layer 214 and the second lens layer 224 and ensure the air gap between the first lens layer 214 and the second lens layer 224.

[0068] Before the first lens layer 214 and the second lens layer 224 are connected, the first moving member and the third moving member move at the same speed so that the first bonding platform 211 and the first adsorption member 213 move synchronously, ensuring the movement of the first lens layer 214. At this time, bending of the first lens layer 214 before connection is avoided.

[0069] The second and fourth moving parts move at the same speed so that the second bonding platform 221 and the second adsorption member 223 move synchronously, ensuring the movement of the second lens layer 224. At this time, bending of the second lens layer 224 before connection is avoided.

[0070] The specific steps are as follows:

[0071] Step S121: The first moving part and the third moving part move synchronously. The first moving part controls the movement of the first bonding platform 211, and the third moving part controls the movement of the first adsorption member 213; or, the second moving part and the fourth moving part move synchronously. The second moving part controls the movement of the second bonding platform 221, and the fourth moving part controls the movement of the second adsorption member 223.

[0072] In the embodiments of this application, the first moving member and the third moving member move synchronously, and drive the first bonding platform 211 and the first suction member 213 to move synchronously, so that the first lens layer 214 moves synchronously with the first bonding platform 211 and the first suction member 213, avoiding the first lens layer 214 from bending before it is connected to the second lens layer 224. At the same time, the first moving member controls the movement of the first bonding platform 211, and the third moving member controls the movement of the first suction member 213. The first moving member and the third moving member are independent of each other, so that the two relatively independent moving systems can act on the first bonding platform 211 and the first suction member 213, ensuring the reverse force on the first lens layer 214 in the later stage, thereby facilitating the bending of the first lens layer 214.

[0073] The second and fourth moving parts move synchronously, driving the second bonding platform 221 and the second suction member 223 to move synchronously. This allows the second lens layer 224 to move synchronously with the second bonding platform 221 and the second suction member 223, preventing the second lens layer 224 from bending before the first lens layer 214 is connected to the second lens layer 224. At the same time, the second moving part controls the movement of the second bonding platform 221, and the fourth moving part controls the movement of the second suction member 223. The second and fourth moving parts are independent of each other, so that the two relatively independent moving systems can act on the second bonding platform 221 and the second suction member 223, ensuring the reverse force on the second lens layer 224 in the later stage, thereby facilitating the bending of the second lens layer 224.

[0074] In step S122, the first lens layer 214 and the second lens layer 224 gradually approach each other, and the first lens layer 214 and the second lens layer 224 are connected by adhesive 230.

[0075] In this embodiment, the first lens layer 214 and the second lens layer 224 gradually approach each other, and the distance between the first lens layer 214 and the second lens layer 224 gradually shortens. When the first lens layer 214 and the second lens layer 224 are connected by the adhesive 230, the states of the third moving member and the fourth moving member are adjusted from a moving state to a stationary state, thereby ensuring that the first adsorption member 213 and the second adsorption member 223 are stationary, while the first moving member and the second moving member are still in a moving state. The first bonding platform 211 applies pressure to the first lens layer 214, and the second bonding platform 221 applies pressure to the second lens layer 224.

[0076] refer to Figure 3 In step S130, when the first lens layer 214 and the second lens layer 224 are connected by the adhesive 230, the first adsorption member 213 stops moving and adsorbs the first lens layer 214, while the first bonding platform 211 continues to move and bends and deforms the first lens layer 214; the second adsorption member 223 stops moving and adsorbs the second lens layer 224, while the second bonding platform 221 continues to move and bends and deforms the second lens layer 224.

[0077] In the embodiments of this application, when the first lens layer 214 and the second lens layer 224 are connected by the adhesive 230, the first adsorption member 213 stops moving and adsorbs the first lens layer 214, while the first bonding platform 211 continues to move and bends the first lens layer 214. At this time, the first lens layer 214 is bent and deformed by the opposing forces of the first adsorption member 213 and the first bonding platform 211.

[0078] The second adsorption member 223 stops moving and adsorbs the second lens layer 224. The second bonding platform 221 continues to move and bends and deforms the second lens layer 224. At this time, the second lens layer 224 is bent and deformed by the opposite forces of the second adsorption member 223 and the second bonding platform 221.

[0079] The specific steps are as follows:

[0080] Step S131: When the first lens layer 214 and the second lens layer 224 are connected by adhesive 230, the first moving member and the third moving member are adjusted from synchronous movement to asynchronous movement.

[0081] Step S132: The third moving part stops moving, causing the first adsorption part 213 to stop moving and adsorb the first lens layer 214;

[0082] Step S133: The first moving part continues to move, causing the first bonding platform 211 to continue to move and bend and deform the first lens layer 214.

[0083] In the embodiments of this application, when the first lens layer 214 and the second lens layer 224 are connected by the adhesive 230, the states of the third and fourth moving members are adjusted from a moving state to a stationary state, thereby ensuring that the first adsorption member 213 and the second adsorption member 223 are stationary, while the first and second moving members are still in a moving state. At this time, the first and third moving members are adjusted from synchronous movement to asynchronous movement in order to control the force exerted by the first patch platform and the first adsorption member 213 on the first lens layer 214, and the first patch platform and the first adsorption member 213 bend and deform the first lens layer 214.

[0084] Step S134: The fourth moving part stops moving, causing the second adsorption part 223 to stop moving and adsorb the second lens layer 224;

[0085] Step S135: The second moving part continues to move, causing the second bonding platform 221 to continue to move and bend and deform the second lens layer 224.

[0086] In the embodiments of this application, when the first lens layer 214 and the second lens layer 224 are connected by the adhesive 230, the states of the third and fourth moving members are adjusted from a moving state to a stationary state, thereby ensuring that the first adsorption member 213 and the second adsorption member 223 are stationary, while the first and second moving members are still in a moving state. At this time, the second and fourth moving members are adjusted from synchronous movement to asynchronous movement to control the force exerted by the second patch platform and the second adsorption member on the second lens layer 224. The second patch platform and the second adsorption member 223 bend and deform the second lens layer 224. Optionally, the first, second, third, and fourth moving members are all moving arms or lifting arms.

[0087] Furthermore, when the first lens layer 214 and the second lens layer 224 are connected by the adhesive 230, the first adsorption member 213 stops moving and adsorbs the first lens layer 214, while the first bonding platform 211 continues to move and bends the first lens layer 214; the second adsorption member 223 stops moving and adsorbs the second lens layer 224, while the second bonding platform 221 continues to move and bends the second lens layer 224. This also includes: both the first adsorption member 213 and the second adsorption member 223 stop moving, while the first bonding platform 211 and the second bonding platform 221 continue to move, causing the first lens layer 214 to be subjected to two opposing forces and the second lens layer 224 to be subjected to two opposing forces; and the first lens layer 214 and the second lens layer 224 are bent and deformed based on these two opposing forces.

[0088] At this time, the non-central region of the first lens layer 214 is subjected to downward elastic pressure, while the central region of the first lens layer 214 is subjected to upward elastic pressure, thereby ensuring the bending effect of the first lens layer 214. The non-central region of the second lens layer 224 is subjected to upward elastic pressure, while the central region of the second lens layer 224 is subjected to downward elastic pressure, thereby ensuring the bending effect of the second lens layer 224.

[0089] In one embodiment, the optical module of the augmented reality (AR) near-eye display device includes an optical engine (or light engine) and a light combiner. The light combiner can directionally transmit the signal light emitted from the optical engine to the human eye to form an image to be displayed on the retina. The light combiner includes a first lens layer 214 and a second lens layer 224. The first lens layer 214 and the second lens layer 224 are waveguide layers or protective layers. The waveguide layer is used for light conduction, and the protective layer is used to prevent steam or dust from entering and to block the influence of external light.

[0090] The frame pasting method also includes:

[0091] The air gap between the first lens layer 214 and the second lens layer 224 is compared with a preset air gap; if the air gap between the first lens layer 214 and the second lens layer 224 is greater than the preset air gap, the movement of the first bonding platform 211 and / or the second bonding platform 221 is stopped, and the curvature of the first lens layer 214 and the second lens layer 224 is maintained.

[0092] In the embodiments of this application, the air gap c between the first lens layer 214 and the second lens layer 224 is compared with a preset air gap d, and the difference between the air gap c between the first lens layer 214 and the second lens layer 224 and the preset air gap d is calculated so as to evaluate the difference between the air gap c between the first lens layer 214 and the second lens layer 224 and the preset air gap d.

[0093] In the embodiments of this application, when the air gap c between the first lens layer 214 and the second lens layer 224 is greater than the preset air gap d, the first lens layer 214 and the second lens layer 224 meet the requirements after being compressed, thereby the lens meets the usage requirements and improves the display effect of the lens.

[0094] At this point, the degree of curvature of the first lens layer 214 should be related to the curvature height. Assuming the curvature height is 'a', which can be measured by a curvature measuring device, and the length of the horizontal reference plane is 'b', the curvature radius of the first lens layer 214 can be calculated as follows:

[0095]

[0096] According to the above formula, by selecting appropriate bonding pressure, Young's modulus of the bonding wafer, and other parameters, the bending height of the first lens layer 214 can be further adjusted. This allows for adjustment of the bonding pressure or bonding parameters, thereby adjusting the bending height of the first lens layer 214. This improves the display effect while preventing excessive bending deformation of the first and second lens layers 224, thus avoiding any impact on their display performance. Similarly, the degree of bending of the first lens layer 214 should be related to the bending height and is subject to the above formula.

[0097] Alternatively, the air gap between the first lens layer 214 and the second lens layer 224 can be measured using a measuring device, which can be a measuring device for measuring air gaps.
