Description

Technical Field

[0001] This utility model relates to the field of microlens processing technology, specifically a positioning fixture for microlens processing. Background Technology

[0002] Microlenses, also known as microlenses, are miniature optical elements with birefringent surfaces and diameters on the micrometer scale. They can focus or adjust the light path through refraction or reflection. The basic form of a microlens is a single lens unit, often integrated in arrays in sensors, imaging systems, and other devices to optimize space utilization and optical performance. Microlenses can be classified into refractive and diffractive types based on their optical design principles. Refractive microlenses, based on traditional geometric optics refraction principles, offer advantages such as small size and high integration, and are mainly used in imaging, beam conversion, optical communication, medical and aesthetic fields. Diffractive microlenses utilize surface relief structures to modulate and change the wave phase of incident light to achieve their target function, primarily used for correcting higher-order aberrations and modulating the shape of light spots with arbitrary light distributions. Microlenses are important miniature optical elements that play a crucial role in optical systems.

[0003] Microlenses, through precise control of their shape, size, and arrangement during fabrication, can achieve specific optical functions. For example, in fields such as optical communication, medicine, and aesthetic medicine, microlenses can be used for beam transformation, imaging, and spot shape modulation to meet diverse application needs. Microlens fabrication typically employs advanced micro-nano manufacturing technologies, such as ion beam etching, thermal remelting, and microplastic imprinting. These technologies enable high-precision control of lens shape and surface quality, ensuring the stability and reliability of optical performance. Microlens fabrication plays a crucial role in realizing functionality, improving precision and efficiency, expanding application areas, and promoting technological innovation and development. During the fabrication of microlens materials using processing equipment, a placement block is needed to support the material. However, the placement block itself cannot clamp and limit the microlens material. Therefore, the microlens material is easily displaced by external forces during fabrication, leading to deviations or material waste. Utility Model Content

Therefore, the microlens materials are easily deviated by external forces during processing, resulting in deviations or waste of materials during processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for microlens processing, comprising a worktable for microlens processing, a placement block, and two assembly boxes. The placement block is located on top of the worktable and is fixedly connected to the top of the worktable.

[0021] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a positioning fixture for microlens processing, including a worktable 1 for microlens processing, a placement block 2, and two assembly boxes 3. The placement block 2 is located on the top of the worktable 1 and is fixedly connected to the top of the worktable 1. The two assembly boxes 3 are located on the front and rear sides of the placement block 2, respectively, and are fixedly connected to the top of the worktable 1.

The two-sided clamping mechanism 4 can stably clamp the microlens material by cooperating with the placement block 2.

[0023] Furthermore, the microlens material is docked with the placement block 2. After docking, the transmission mechanism 6 is activated, which drives the adjustment mechanism 5.

[0025] Specifically, the cooperation of the two clamping mechanisms 4 on both sides can stably clamp the microlens material, preventing the microlens material from shifting at the top of the placement block 2.

[0026] Furthermore, during the movement of the moving block 401, the clamping plate 403 will be moved by the connecting plate 402. During the movement, the clamping plate 403 will fit and dock with the surface of the microlens material. After docking, the clamping plate 403 will stably clamp the microlens material through its own material properties, thereby avoiding the problem of the microlens material shifting during processing. Example

[0027] In the third embodiment of this utility model, the adjusting mechanism 5 includes two rotating shaft blocks 501, a lead screw 502, and a connecting gear 503.

The connecting gear 503 is located on the front side of the assembly box 3 and is rotatably connected to the inner wall of the assembly box 3. The rear side of the connecting gear 503 passes through the inner wall of the assembly box 3 and the rotating shaft blocks 501 and is fixedly connected to the front side of the lead screw 502. The surface of the lead screw 502 is threadedly connected to the inner cavity of the moving block 401.

The transmission gear 602 is located at the output end of the rotary motor 601 and is fixedly connected to the output end of the rotary motor 601. The surface of the transmission gear 602 meshes with the inner cavity of the rack 603. The left and right sides of the inner cavity of the rack 603 mesh with the surface of the connecting gear 503. Limiting blocks 7 are fixedly connected to the left and right sides of the inner cavity of the assembly box 3. A slider 8 is slidably connected to the inner cavity of the limiting block 7. The side of the slider 8 near the moving block 401 is fixedly connected to the surface of the moving block 401. A protective shell 9 is fixedly connected to the front side of the assembly box 3. The transmission gear 602, rack 603 and connecting gear 503 are all located in the inner cavity of the protective shell 9. A mounting plate 10 is fixedly connected to the bottom of the rotary motor 601. The bottom of the mounting plate 10 is fixedly installed to the inner wall of the assembly box 3 by bolts.

[0028] Specifically, the transmission mechanism 6, through its cooperation with the adjustment mechanism 5, enables the clamping mechanism 4 to quickly dock with the microlens material, thus avoiding situations where the clamping mechanism 4 cannot be quickly docked with the microlens material.

[0029] Furthermore, the rotary motor 601 is started, which drives the rack 603 to rotate through the transmission gear 602. During the rotation of the rack 603, the rack drives the connecting gears 503 on both sides to rotate. During the rotation of the connecting gears 503, the connecting gears 503 drive the lead screw 502 to rotate. During the rotation of the lead screw 502, the lead screw 502 drives the moving block 401 to move through the threaded connection with the moving block 401, thereby achieving the function of quickly driving the clamping mechanism 4 to dock with the microlens material.

[0030] When the rotary motor 601 is started, it drives the rack 603 to rotate via the transmission gear 602. During the rotation of the rack 603, it drives the connecting gears 503 on both sides to rotate. During the rotation of the connecting gears 503, it drives the lead screw 502 to rotate. During the rotation of the lead screw 502, it drives the moving block 401 to move through the threaded connection with the moving block 401. During the movement of the moving block 401, it drives the clamping plate 403 to move through the connecting plate 402. During the movement, the clamping plate 403 will fit and mate with the surface of the microlens material. After the mating is completed, the clamping plate 403 will stably clamp the microlens material based on its own material properties, thereby preventing the microlens material from shifting during processing.

[0031] In summary, the stable clamping effect of the microlens material is achieved through the cooperation of the worktable 1, the placement block 2, the assembly box 3, the clamping mechanism 4, the adjustment mechanism 5, and the transmission mechanism 6.
