Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lens stacking technology, and specifically relates to an AR lens stacking mechanism. Background Technology
[0002] In the current field of AR lenses, there are operational steps involved in stacking two AR lenses.
[0003] The existing procedure for stacking two AR lenses involves stacking the AR lenses using a close-gap method. The support of gap particles (with uniform diameter) within the bonding adhesive ensures good parallelism of the stacked AR lenses. For example,... Figure 1 The diagram illustrates the stacking operation of two AR lenses. One AR lens is placed on the upper stacking platform, and the other AR lens is placed on the lower stacking platform. A stacking adhesive containing gap particles is applied to the AR lens on the lower stacking platform. Pressure is applied to the upper stacking platform, and the two AR lenses are stacked together using the stacking adhesive containing gap particles. The gap particles in the stacking adhesive provide support, ensuring that the two stacked AR lenses have good parallelism.
[0004] When an AR lens on an upper stacking stage and an AR lens on a lower stacking stage are stacked using a bonding adhesive containing gap particles, and the stacking gap is set to a fixed value, if the thickness uniformity of the AR lenses to be stacked is poor, the stacking gap will be smaller in the thicker parts of the AR lenses. When the stacking gap is smaller than the diameter of the gap particles, the gap particles will suffer overpressure damage, resulting in poor parallelism of the stacked AR lenses. Figures 1-2 As shown.
[0005] If the parallelism of the upper and lower stacking stages is poor, the size of the bonding gap between the AR lenses on the upper and lower stacking stages, which are bonded together using bonding adhesive containing gap particles, will be inconsistent. This will result in uneven pressure on the gap particles, meaning that the gap particles in areas with smaller bonding gaps will experience greater pressure than those in areas with larger bonding gaps. Consequently, the gap particles will deform inconsistently, leading to poor parallelism of the laminated AR lenses (e.g., ...). Figure 3 (As shown). Utility Model Content

[0026] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:
[0027] This invention provides an AR lens stacking mechanism, including a first stage, a second stage, a first stacking platform, a second stacking platform, and a support block. The bottom surface of the first stage is connected to the top surface of the first stacking platform, and the top surface of the second stage is connected to the bottom surface of the second stacking platform.

Meanwhile, the AR lens stacking mechanism provided by this utility model has a simple structure and is easy to operate. Attached Figure Description

[0038] In this description, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0039] like Figure 4 As shown, this utility model provides an AR lens stacking mechanism, including a first stage 1, a second stage 2, a first stacking platform 3, a second stacking platform 4, and a support block 5.
[0040] The bottom surface of the first platform 1 is connected to the top surface of the first stacking platform 3, and the top surface of the second platform 2 is connected to the bottom surface of the second stacking platform 4.
[0041] The bottom surface of the first lamination platform 3 is used to mount the first AR lens, and the top surface of the second lamination platform 4 is used to mount the second AR lens. For example, the first AR lens is adsorbed into the inner region of the bottom surface of the first lamination platform, and the second AR lens is adsorbed into the inner region of the top surface of the second lamination platform. The first AR lens and the second AR lens are laminated and connected using an adhesive.
[0042] When the first AR lens and the second AR lens are laminated using laminating adhesive, there is a gap between the first laminating platform and the second laminating platform. The gap is set according to the thickness of the first AR lens, the second AR lens, and the laminating gap.
[0043] A support block is set between the bottom surface of the first stacking platform and the top surface of the second stacking platform. The height of the support block is equal to the sum of the thicknesses of the first AR lens, the second AR lens, and the stacking gap. The stacking gap is the stacking gap between the first AR lens and the second AR lens when they are stacked using a stacking adhesive.
[0044] Regarding the placement of the support block between the bottom surface of the first stacked platform and the top surface of the second stacked platform, the support block can be placed at the edge region of the bottom surface of the first stacked platform, or at the edge region of the top surface of the second stacked platform. For example, as shown... Figure 4 as well as Figure 5 As shown, support blocks 5 can be set in the four corner areas of the top edge of the second stacking platform 4.
[0045] The support block controls the size of the lamination gap between the first and second AR lenses during the lamination process, preventing excessive pressure damage to gap particles within the lamination adhesive and ensuring the parallelism of the AR lenses during lamination. Furthermore, the AR lens lamination mechanism provided by this invention has a simple structure and is easy to operate.
[0046] Furthermore, depending on the thickness of the AR lenses and the different stacking gaps, the size of the stacking gap between the first and second AR lenses can be controlled by replacing the support blocks of the corresponding height, preventing excessive pressure damage to the gap particles in the stacking adhesive and ensuring the parallelism of the AR lens stacking operation.
[0047] To facilitate the control of the downward movement of the first stacking stage to achieve the stacking operation of the first AR lens and the second AR lens, as a preferred embodiment, such as... Figure 4 As shown, the AR lens stacking mechanism of this utility model may further include a thrust component 6. The fixed end of the thrust component 6 is disposed on the bottom surface of the first platform 1, and the pushing end of the thrust component 6 is connected to the top surface of the first stacking platform 3. For example, the thrust component may be an existing cylinder, with the base of the cylinder disposed on the edge region of the bottom surface of the first platform, and the piston rod of the cylinder connected to the top surface of the first stacking platform.
[0048] In order to facilitate pressing the first stage down to the corresponding position for subsequent stacking operations of the first AR lens and the second AR lens, as a preferred embodiment, the AR lens stacking mechanism of this utility model may further include a lifting and adjusting device.
[0049] like Figure 4 As shown, the lifting and adjusting device includes a support frame 7, a drive component 8, a transmission component 9, and a moving component. The drive component 8 is mounted on the support frame 7 and is connected to the transmission component 9. The transmission component 9 is connected to the moving component, which is mounted on the support frame and connected to the top surface of the first platform.
[0050] For example, the moving parts may include a moving block 10-1, a guide rail 10-2, and a slider 10-3.
[0051] The guide rail 10-2 is mounted on the support frame 7. The top end of the slider 10-3 is connected to the side of the moving block 10-1, and the bottom end of the slider 10-3 is slidably connected to the guide rail 10-2. The top end of the moving block 10-1 is connected to the transmission component 9, and the bottom end of the moving block 10-1 is connected to the top surface of the first platform 1.
[0052] For example, the driving component here can be a drive motor, and the transmission component here can be a lead screw.
[0053] The AR lens stacking operation using the AR lens stacking mechanism of this utility model is as follows:
[0054] 1. Vacuum-adhere the first AR lens to the inner region of the bottom surface of the first lamination platform, vacuum-adhere the second AR lens to the inner region of the top surface of the second lamination platform, and apply lamination adhesive containing interstitial particles to the second AR lens.
[0055] 2. The lifting and adjusting device controls the first platform to move downward to the corresponding position.
[0056] 3. Activate the thrust component, which pushes the first lamination platform downward to contact the support block located at the top edge of the second AR lens, so that the first AR lens and the second AR lens are laminated together using an adhesive containing gap particles.
[0057] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art can still make modifications or equivalent substitutions to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model are within the protection scope of the claims of this utility model pending approval.
