Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and specifically discloses an optical lens coating holder. Background Technology

[0002] The production of optical lenses requires strict control over key indicators such as material purity, optical transparency, and surface uniformity. Taking a 1.67 high-refractive-index polarized lens as an example, it achieves a comprehensive improvement in lens thinness, anti-glare, and scratch resistance by integrating high-refractive-index materials, polarization control technology, and multi-layer coating processes. In the manufacturing process, the coating process is a core step, requiring the deposition of single or multiple optical thin films on the lens surface using physical or chemical processes. This thin film precisely achieves core functions such as light focusing, wavefront correction, spectral selection, and refractive index matching by controlling the reflection and transmission interference effects generated by incident light at the film layer interface, thereby endowing the lens with specific optical properties. During the coating process, the optical lens needs to be positioned to prevent movement.

[0003] In optical lens coating processes, existing technologies mainly employ the following two positioning methods. The first is the positioning groove nesting method: by creating a positioning groove on the coating holder that matches the lens, the lens is embedded into the hole to restrict its displacement. The second is the mechanical clamping method: using mechanical clamping force to apply pressure to the lens edge to fix the lens in place.

[0004] However, the method of positioning optical lenses using positioning slots has drawbacks. Since the optical lenses are embedded inside the positioning slots, it is inconvenient to remove them after coating is completed. On the other hand, mechanical clamping methods require the optical lenses to be subjected to rigid clamping forces, which could potentially damage them. Therefore, an optical lens coating holder is needed to solve this problem. Utility Model Content

[0007] An adsorption mechanism is provided between the two upright plates. The adsorption mechanism includes an air cavity opened inside the fixed plate.

[0008] A limiting mechanism is provided above the fixed plate. The limiting mechanism includes multiple limiting holes opened at the upper end of the lifting plate.

[0017] After the coating is completed, the constraint on the downward movement of the lifting plate is released by the two limiting plates moving in opposite directions. Then, the lifting plate is pressed down to below the two limiting plates, and at the same time, multiple return springs are compressed. Then, the two limiting plates move relative to each other and abut against the upper end of the lifting plate. At this time, multiple lenses are disengaged from the interior of multiple positioning holes. Then, the air pump is turned off, and the lenses can be removed, thus achieving the purpose of conveniently removing the optical lenses after coating. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-4 An optical lens coating base includes two upright plates 1 distributed on the left and right, a fixing plate 2 installed between the two upright plates 1, and a lifting plate 3 located between the two upright plates 1 above the fixing plate 2. The outer wall of the lifting plate 3 is provided with a plurality of evenly distributed positioning holes 4.

[0026] An adsorption mechanism is provided between the two upright plates 1. The adsorption mechanism includes an air cavity 7 opened inside the fixed plate 2. Multiple vertical pipes 8 connected to the air cavity 7 are installed at the upper end of the fixed plate 2. Adsorption heads 5 extending into multiple positioning holes 4 are installed at the upper end of each of the multiple vertical pipes 8. Ventilation holes 6 connected to the vertical pipes 8 are opened through the upper end of each of the multiple adsorption heads 5. An air pump 19 with an air inlet end extending into the air cavity 7 is installed at the lower end of the fixed plate 2.

[0027] A limiting mechanism is provided above the fixed plate 2. The limiting mechanism includes multiple limiting holes 9 opened at the upper end of the lifting plate 3. Each of the multiple limiting holes 9 is provided with a limiting plate 10 that fits against the lower end of its inner wall. Multiple return springs 14 are installed between the lifting plate 3 and the fixed plate 2. Guide frames 11 are fixedly connected through the outer walls of the two upright plates 1. Each of the two guide frames 11 is provided with a limiting plate 12 that fits against the lower end of the lifting plate 3. A screw 13 that passes through the guide frame 11 and is threadedly connected to the opposite side of the two limiting plates 12 is rotatably connected. A torsion block 16 is installed on the opposite side of the two screws 13.

[0028] In this embodiment: the lenses to be coated are embedded one by one into the multiple positioning holes 4 of the lifting plate 3. The initial positioning is completed by the adaptation of the hole wall of the positioning hole 4 with the lens. Then the air pump 19 is started. Since the vertical pipe 8 is connected to the air chamber 7 and the vent 6 is connected to the vertical pipe 8, a negative pressure can be formed inside the vent 6. The upper ends of the multiple adsorption heads 5 are all in contact with the multiple lenses. The multiple lenses are fixed by negative pressure adsorption. In this way, the purpose of avoiding damage to the optical lenses is achieved.

[0029] Since multiple limiting discs 10 are in contact with the lower side of the inner wall of multiple limiting holes 9 respectively, and two limiting plates 12 are in contact with the lower end of the lifting plate 3, the lifting plate 3 is prevented from moving. After the coating is completed, the two screws 13 are rotated by two torsion blocks 16 to make the two limiting plates 12 move in opposite directions until the constraint on the downward movement of the lifting plate 3 is released. Then the lifting plate 3 is pressed down, and multiple return springs 14 are compressed until the lifting plate 3 is below the two limiting plates 12. Then the two screws 13 are reversed to make the two limiting plates 12 move relative to each other. Due to the rebound force of the return springs 14, the lifting plate 3 can abut against the lower end of the two limiting plates 12. At this time, multiple lenses are disengaged from the interior of multiple positioning holes 4 respectively. Then the air pump 19 is turned off, and the lenses can be removed. In this way, the purpose of conveniently removing the optical lenses after coating is achieved.

[0030] After the lens is removed, the upward movement restriction of the lifting plate 3 is released, and multiple reset springs 14 release elastic potential energy, pushing the lifting plate 3 to move upward and return to its original position. The bottom of the limiting plate 10 and the limiting hole 9 come into contact again, and the limiting plate 12 locks the position of the lifting plate 3 again, preparing for the next round of coating operation.

[0031] As a technical optimization of this utility model, guide holes 21 are provided through the bottom side of the inner wall of the multiple limiting holes 9, and guide rods 20 are installed at the lower end of the multiple limiting discs 10, which pass through the multiple guide holes 21 and are fixedly connected to the fixing plate 2. The multiple guide rods 20 are respectively adapted to the multiple guide holes 21.

[0032] In this embodiment: the guide rod 20 cooperates with the guide hole 21 to ensure that the lifting plate 3 moves vertically without deviation.

[0033] As a technical optimization of this utility model, the multiple adsorption heads 5 are all made of ceramic material and have a smooth spherical structure at the top.

[0034] In this embodiment: because the ceramic material has high hardness and wear resistance, it avoids scratching the lens surface. Because the upper end of the adsorption head 5 has a spherical structure, it is convenient for the adsorption head 5 to fit with the lens.

[0035] As a technical optimization of this utility model, each of the multiple guide frames 11 has two sliding grooves 17 inside, and each of the two limiting plates 12 has two sliders 18 installed on its outer wall. The four sliders 18 are slidably connected to the interior of the four sliding grooves 17 respectively.

[0036] In this embodiment, by setting four sliding grooves 17 and four sliders 18, the limiting plate 12 is prevented from shifting, thus ensuring the limiting accuracy.

[0037] As a technical optimization of this utility model, multiple reset springs 14 are respectively sleeved on the outside of multiple guide rods 20.

[0038] In this embodiment: because the return spring 14 is compressed or extended along the guide rod 20, the movement trajectory is stable, avoiding the lifting plate 3 from jamming due to the tilt of the return spring 14.

[0039] As a technical optimization of this utility model, guide heads 15 are installed on opposite sides of the two limiting plates 12.

[0040] In this embodiment, the guide head 15 has a guiding effect, preventing the limiting plate 12 from misaligning with the lifting plate 3.

[0041] As a technical optimization of this utility model, all the vertical tubes 8 are made of rigid plastic.

[0042] In this embodiment: Since the multiple vertical tubes 8 are all made of rigid plastic, bending of the vertical tubes 8 is prevented, thereby avoiding changes in the position and orientation of the adsorption head 5.

[0043] The working principle and usage process of this utility model are as follows: First, the lenses to be coated are embedded one by one into the multiple positioning holes 4 of the lifting plate 3. The initial positioning is completed by the adaptation between the hole wall of the positioning hole 4 and the lens. Then, the air pump 19 is started. Since the vertical pipe 8 is connected to the air chamber 7 and the vent 6 is connected to the vertical pipe 8, a negative pressure can be formed inside the vent 6. The upper ends of the multiple adsorption heads 5 are all in contact with the multiple lenses. The multiple lenses are fixed by negative pressure adsorption. In this way, the purpose of avoiding damage to the optical lenses is achieved.

[0044] Since multiple limiting discs 10 are in contact with the lower side of the inner wall of multiple limiting holes 9 respectively, and two limiting plates 12 are in contact with the lower end of the lifting plate 3, the lifting plate 3 is prevented from moving. After the coating is completed, the two screws 13 are rotated by two torsion blocks 16 to make the two limiting plates 12 move in opposite directions until the constraint on the downward movement of the lifting plate 3 is released. Then the lifting plate 3 is pressed down, and multiple return springs 14 are compressed until the lifting plate 3 is below the two limiting plates 12. Then the two screws 13 are reversed to make the two limiting plates 12 move relative to each other. Due to the rebound force of the return springs 14, the lifting plate 3 can abut against the lower end of the two limiting plates 12. At this time, multiple lenses are disengaged from the interior of multiple positioning holes 4 respectively. Then the air pump 19 is turned off, and the lenses can be removed. In this way, the purpose of conveniently removing the optical lenses after coating is achieved.

[0045] After the lens is removed, the upward movement restriction of the lifting plate 3 is released, and multiple reset springs 14 release elastic potential energy, pushing the lifting plate 3 to move upward and return to its original position. The bottom of the limiting plate 10 and the limiting hole 9 come into contact again, and the limiting plate 12 locks the position of the lifting plate 3 again, preparing for the next round of coating operation.

Therefore, they should not be construed as limitations on this utility model.

Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
