Description

Technical Field

[0001] The utility model relates to the technical field of lens processing, in particular to an optical lens ink coating positioning and rotating mechanism. Background Technique

[0002] In the optical industry, lenses are an indispensable and important part. They have relatively excellent optical properties, light transmittance, mechanical and chemical properties, and have a constant refractive index, with stable use performance. However, in an optical system, stray light inevitably appears in lenses. Stray light will reduce the level of the entire picture, lower the contrast, deteriorate the clarity, and in severe cases, form stray light spots of different shapes and sizes, and even cause the use performance of the lens to fail. To improve the situation of stray light, the lens is usually subjected to ink coating treatment. The main purpose of the ink coating treatment is to absorb the stray light outside the effective aperture of the optical lens, avoid the stray light passing through to the photosensitive chip to form unnecessary glare and affect the imaging quality. However, the existing ink coating devices have poor positioning effects on the lenses, making the positions of the lenses prone to tilt and shift, resulting in uneven ink coating, wasting the ink usage amount, affecting the ink coating quality, and reducing the ink coating efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide an optical lens ink coating positioning and rotating mechanism aiming at the deficiencies of the prior art, realizing the positioning and clamping of the lens position, ensuring the uniformity and accuracy of the lens ink coating while saving the ink usage amount, and improving the ink coating efficiency and ink coating quality.

[0004] To achieve the above purpose, an optical lens ink coating positioning and rotating mechanism of the utility model includes a workbench, a material clamping device movably arranged on the workbench, an ink coating device used in cooperation with the material clamping device, and a driving member drivingly connected to the ink coating device. The material clamping device is used for clamping the lens and placing the lens on the ink coating device, so that the driving member drives the ink coating device to rotate to perform ink coating treatment on the lens.

[0005] Preferably, the material clamping device includes two relatively arranged material clamping components and a limiting member arranged between the two material clamping components. Each material clamping component includes a mounting seat, a driving cylinder drivingly connected to the mounting seat, a micrometer arranged at one end of the mounting seat, and a clamping jaw arranged at the other end of the mounting seat. The driving cylinder drives the clamping jaw to approach the limiting member through the mounting seat, so that the measuring end of the micrometer abuts against the limiting member.

[0006] Preferably, a buffer member is arranged at one end of the mounting seat close to the micrometer, and the buffer member is used for buffering the impact force between the micrometer and the limiting member.

[0007] Preferably, a guide rail is arranged on the workbench, and a slider slidably connected to the guide rail is arranged on the mounting seat.

[0008] Preferably, the ink coating device includes a main shaft sleeve, a rotating shaft rotatably arranged in the main shaft sleeve, an ink applicator arranged on the rotating shaft, a ventilation channel arranged in the rotating shaft, a connector arranged in the ventilation channel, and a driven synchronous pulley sleeved outside the rotating shaft. The driving member is drivingly connected to the driven synchronous pulley, and the ventilation channel penetrates through the rotating shaft to communicate with the connector.

[0009] Preferably, bearings are arranged at both ends of the main shaft sleeve, and the bearings are sleeved outside the rotating shaft.

[0010] Preferably, the driving member includes a mounting bracket, a stepping motor arranged on the mounting bracket, and a driving synchronous pulley drivingly connected to the stepping motor. A transmission belt is connected between the driving synchronous pulley and the driven synchronous pulley.

[0011] The beneficial effects of the present utility model are as follows: The position of the lens can be positioned and clamped, ensuring the uniformity and accuracy of the ink coating on the lens while also saving the ink usage amount, and improving the ink coating efficiency and quality.

[0026] The present utility model will be described in detail below with reference to the accompanying drawings.

[0027] As Figures 1 to 3 shown, an ink - coating positioning and rotating mechanism for an optical lens of the present utility model includes a workbench 1, a material - clamping device 2 movably arranged on the workbench 1, an ink - coating device 3 used in cooperation with the material - clamping device 2, and a driving member 4 drivingly connected to the ink - coating device 3. The material - clamping device 2 is used for clamping the lens and placing the lens on the ink - coating device 3, so that the driving member 4 drives the ink - coating device 3 to rotate to perform ink - coating treatment on the lens.

[0028] During operation, the material - clamping device 2 pushes back and forth to perform two clamping operations on the lens to be ink - coated, thereby playing a role in clamping and positioning the lens and stably placing the lens on the ink - coating device 3. Moreover, the ink - coating device 3 positions and adsorbs the lens, and the material - clamping device 2 moves away from the lens and releases the clamping and positioning effect on the lens. When the driving member 4 drives the ink - coating device 3 to rotate, the lens is driven to rotate together, so that the ink - coating device 3 evenly sprays ink on the surface of the lens, and the rotation movement of the lens is used to make the ink evenly distributed, ensuring the uniformity of ink - coating. The center - positioning adsorption deviation of this mechanism is within plus or minus 0.001 mm, which is applicable to the positioning and rotating ink - coating of glass lenses and plastic lenses. The ink - coating range of the lens is between 4 mm and 20 mm in diameter. The present utility model realizes positioning and clamping the position of the lens, ensures the uniformity and accuracy of lens ink - coating while saving the ink usage amount, and improves the ink - coating efficiency and ink - coating quality.

[0029] The material clamping device 2 of this embodiment includes two relatively arranged material clamping components 21 and a limiting member 22 arranged between the two material clamping components 21. The material clamping component 21 includes a mounting seat 211, a driving cylinder 212 drivingly connected to the mounting seat 211, a micrometer 213 arranged at one end of the mounting seat 211, and a clamping jaw 214 arranged at the other end of the mounting seat 211. The driving cylinder 212 drives the clamping jaw 214 to approach the limiting member 22 through the mounting seat 211, so that the measuring end of the micrometer 213 abuts against the limiting member 22. Specifically, the two material clamping components 21 are placed opposite to each other, and the ink coating device 3 is placed between the two material clamping components 21. Before the ink coating operation, the position of the measuring end of the micrometer 213 needs to be adjusted according to the specification size of the lens, so that the position where the clamping jaw 214 clamps and fixes the lens is more accurate and tight, and the positioning accuracy is high. When the driving cylinder 212 drives the mounting seat 211 to move in the direction close to the ink coating device 3, the measuring end of the micrometer 213 abuts against the limiting member 22, effectively preventing the clamping jaw 214 from excessively clamping the lens and causing the lens to be squeezed and cracked. By pushing the two clamping jaws 214 back and forth to clamp the circular lens twice, the positioning is effectively and accurately carried out and the center is automatically found. The limiting member 22 can be a limiting post, a limiting rod, a limiting shaft, etc.

[0030] One end of the mounting seat 211 of this embodiment close to the micrometer 213 is provided with a buffer member 215, and the buffer member 215 is used to buffer the impact force between the micrometer 213 and the limiting member 22. Specifically, the buffer member 215 can be a buffer pin, a buffer pad, a buffer rubber, etc. For relatively fragile parts of the lens, it is easy to be squeezed and impacted during the ink coating process. At this time, using the buffer member 215 can provide a certain buffering effect, effectively reducing the influence of the impact force and ensuring the yield rate of the lens.

[0031] The workbench 1 of this embodiment is provided with a guide rail 11, and the mounting seat 211 is provided with a slider 216 slidably connected to the guide rail 11. Specifically, the driving cylinder 212 drives the mounting seat 211 to move along the workbench 1, and the mounting seat 211 is slidably connected to the guide rail 11 through the slider 216, reducing the frictional resistance and moving smoothly and quickly.

[0032] The ink coating device 3 of this embodiment includes a main shaft sleeve 31, a rotating shaft 32 rotatably arranged in the main shaft sleeve 31, an ink applicator 33 arranged on the rotating shaft 32, a ventilation channel 34 arranged in the rotating shaft 32, a connector 35 arranged in the ventilation channel 34, and a driven synchronous pulley 36 sleeved outside the rotating shaft 32. The driving member 4 is drivingly connected to the driven synchronous pulley 36, and the ventilation channel 34 penetrates through the rotating shaft 32 to communicate with the connector 35. Specifically, the driving member 4 drives the driven synchronous pulley 36 to rotate, and the rotating driven synchronous pulley 36 drives the rotating shaft 32 to rotate. An external air pump is communicated with the ventilation channel 34 through the connector 35. When the clamping jaw 214 places the lens at the top of the rotating shaft 32, a negative pressure is generated by the ventilation channel 34 to firmly adsorb the lens, so that the lens rotates together with the rotating shaft 32. The ink applicator 33 is also arranged on the rotating shaft 32. The ink applicator 33 sprays ink on the surface of the lens, and the rotation of the lens is used to evenly distribute the ink, thereby completing the rotating ink coating work of the lens.

[0033] Bearings 37 are arranged at both ends of the main shaft sleeve 31 of this embodiment, and the bearings 37 are sleeved outside the rotating shaft 32. Specifically, the outer ring of the bearing 37 abuts against the inner wall of the main shaft sleeve 31, and the inner ring of the bearing 37 is sleeved on the outer wall of the rotating shaft 32, effectively supporting the rotating shaft 32 and reducing the friction coefficient of the rotating shaft 32 during rotation to ensure the rotation accuracy.

[0034] The driving member 4 of this embodiment includes a mounting frame 41, a stepping motor 42 arranged on the mounting frame 41, and a drivingly connected to the stepping motor 42. An active synchronous pulley 43, and a transmission belt 44 is connected between the active synchronous pulley 43 and the driven synchronous pulley 36. Specifically, the mounting frame 41 is correspondingly installed and fixed at a suitable working position. The stepping motor 42 drives the active synchronous pulley 43 to rotate, and the rotating active synchronous pulley 43 further drives the driven synchronous pulley 36 to rotate through the transmission belt 44, and then the rotating driven synchronous pulley 36 drives the rotating shaft 32 to rotate, with high transmission efficiency.

For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present invention.
