Description

Technical Field

[0001] This utility model relates to the technical field of optical lens inspection, specifically to an optical lens inspection fixture. Background Technology

[0002] During the production and acceptance process, optical lenses need to undergo visual inspection to ensure that there are no defective products. Currently, this is usually done by manually picking up the optical lenses for visual inspection. When inspecting optical lenses, both sides of the lens are usually inspected.

[0003] However, when inspecting optical lenses, the surface of optical glass or resin lenses naturally reflects light, causing the lens to have reflective properties. Therefore, it is necessary to rotate the lens at a certain angle to perform a full-range inspection. However, existing inspection fixtures can only rotate the optical lens by about 180 degrees, and the operation is relatively cumbersome, which is basically unacceptable for lenses that require rotation at specific angles. Therefore, we provide an optical lens inspection fixture to solve the above problems. Utility Model Content

[0004] Technical problem solved: This utility model proposes an optical lens inspection fixture. Through the cooperation between the adjusting rod, the positioning rod, and the positioning hole, pulling the sliding rod compresses the spring, causing the positioning rod to disengage from the positioning hole. Rotating the adjusting rod rotates the lens to a suitable angle. Releasing the sliding rod then engages the positioning rod with the corresponding positioning hole. This solves the problem that when inspecting optical lenses, due to their reflective properties, they need to be rotated at a certain angle for comprehensive inspection. Existing inspection fixtures can only rotate the optical lens by 180 degrees, and the operation is relatively cumbersome. For lenses requiring rotation at specific angles, this fixture is generally unsuitable.

[0005] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: an optical lens inspection fixture, including a base plate, a support plate fixedly connected to the upper surface of the base plate, a sliding plate slidably connected inside the support plate, an adjusting rod rotatably passing through the inside of the sliding plate, a fixing ring fixedly connected to one end of the adjusting rod, a lens body disposed inside the fixing ring, and a connecting plate fixedly connected to the outer surface of the adjusting rod; A sliding rod slides through the outer surface of the connecting plate. One end of the sliding rod is fixedly connected to an end plate. A spring is sleeved on the outside of the sliding rod. One end of the spring is fixedly connected to the outer surface of the end plate, and the other end of the spring is fixedly connected to the outer surface of the connecting plate. A positioning rod is fixedly connected to one end of the end plate.

[0006] Furthermore, a hydraulic rod is fixedly installed on the outer surface of the support plate, and the top end of the hydraulic rod is fixedly connected to the bottom surface of the slide plate.

[0012] Beneficial effects: Compared with the prior art, this optical lens inspection fixture has the following beneficial effects: I. This optical lens inspection fixture, through the cooperation of an adjusting rod, a positioning rod, and a positioning hole, allows for angle adjustment of the lens body. Pulling the sliding rod compresses the spring, disengaging the positioning rod from the positioning hole. Rotating the adjusting rod rotates the lens to the appropriate angle. Releasing the sliding rod allows the positioning rod to engage with the corresponding positioning hole, thus fixing the adjusted lens body in place. This solves the problem that, during optical lens inspection, due to the reflective nature of the lens, it is necessary to rotate it at a certain angle for comprehensive inspection. Existing inspection fixtures can generally only rotate the optical lens 180 degrees, and the operation is cumbersome, failing to meet the needs of lenses requiring specific angle rotation.

[0013] II. This optical lens inspection fixture, through the cooperation between the fixing ring, screw, adjusting plate and arc plate, when using the device, the lens body to be inspected is placed inside the fixing ring, the screw is rotated, the screw drives the arc plate to move close to the side of the lens body, clamping and fixing the lens body, preventing it from falling off when the lens body is rotated, causing damage to the lens body.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The hydraulic rod in this utility model is a common hydraulic device in the prior art, and this application will not elaborate on its model or internal structure.

[0018] like Figure 1-5 As shown, this utility model provides a technical solution: an optical lens inspection fixture, including a base plate 1, with mounting holes on the outer surface of the base plate 1 to fix the base plate 1 and ensure the stability of the device during inspection. A support plate 2 is fixedly connected to the upper surface of the base plate 1. The base plate 1 and the support plate 2 are made of high-strength aluminum alloy, which has high rigidity, wear resistance and dimensional stability, ensuring that the fixture maintains long-term accuracy in precision inspection.

[0019] The support plate 2 has a sliding plate 3 inside, and a groove 13 is opened on the outer surface of the support plate 2. The outer surface of the sliding plate 3 is slidably connected to the inner wall of the groove 13. A protrusion is opened on the side of the sliding plate 3, which is embedded in the inner wall of the groove 13, so that the sliding plate 3 can move up and down horizontally and prevent it from falling out of the groove 13. A hydraulic rod 12 is fixedly installed on the outer surface of the support plate 2. The top end of the hydraulic rod 12 is fixedly connected to the bottom surface of the sliding plate 3. The hydraulic rod 12 has a cylinder, piston, piston rod and seals inside. The working principle of the hydraulic rod 12 is based on Pascal's law, that is, the pressure applied to a closed liquid will be evenly transmitted to all parts of the liquid. Through this force transmission method, the hydraulic rod 12 can realize the support and motion control of the external load.

[0020] The internal rotation of the slide plate 3 is traversed by an adjusting rod 4. The outer surface of the slide plate 3 is plated with hard chrome to reduce the coefficient of friction. The adjusting rod 4 is made of stainless steel. A circular piece 16 is fixedly connected to the outer surface of the adjusting rod 4. The outer surface of the circular piece 16 is rotatably connected to the internal rotation of the slide plate 3. The circular piece 16 slides inside the slide plate 3. The circular piece 16 is designed to prevent the adjusting rod 4 from sliding left and right inside the slide plate 3.

[0021] One end of the adjusting rod 4 is fixedly connected to a fixing ring 5, and the lens body 6 is set inside the fixing ring 5. An angle scale 20 is fixedly connected to the outer surface of the sliding plate 3, and a scale 21 is fixedly connected to the outer surface of the adjusting rod 4. The outer surface of the scale 21 is slidably connected to the outer surface of the angle scale 20. When adjusting the angle of the lens body 6, the adjusting rod 4 drives the scale 21 to slide on the outer surface of the angle scale 20. The lens body 6 can be rotated to a suitable angle by referring to the angle scale 20.

[0022] A screw 17 is threaded onto the outer surface of the fixing ring 5. An adjusting plate 18 is fixedly connected to one end of the screw 17. An arc plate 19 is rotatably connected to the outer surface of the adjusting plate 18. The arc plate 19 presses and fixes the lens body 6. The outer surface of the arc plate 19 is made of polyurethane rubber to avoid scratching the lens surface and to provide uniform clamping force. When the arc plate 19 is about to contact the lens body 6, hold the arc plate 19 by hand to keep it horizontal, and continue to rotate the screw 17. At this time, the adjusting plate 18 will slide inside the arc plate 19, so that the arc plate 19 moves horizontally. A connecting plate 7 is fixedly connected to the outer surface of the adjusting rod 4.

[0023] A sliding rod 8 slides through the outer surface of the connecting plate 7. One end of the sliding rod 8 is fixedly connected to an end plate 9. A spring 10 is sleeved on the outside of the sliding rod 8. One end of the spring 10 is fixedly connected to the outer surface of the end plate 9, and the other end of the spring 10 is fixedly connected to the outer surface of the connecting plate 7. A positioning rod 11 is fixedly connected to one end of the end plate 9. A positioning ring 14 is fixedly connected to the outer surface of the slide plate 3. The outer surface of the positioning ring 14 has evenly distributed positioning holes 15. The outer surface of the positioning rod 11 slides through the inner wall of the positioning hole 15. There are ten positioning holes 15 in total. The angle between two adjacent positioning holes 15 is ten degrees. When rotating the lens body 6, this angle should be the product of ten. The spring 10 is made of high-elasticity stainless steel. The surface of the positioning rod 11 is nickel-plated to prevent oxidation and ensure stable elastic reset performance. The arc plate 19 has two parts, including its arc-shaped plate and its outer circular sleeve.

[0024] Working principle: In use, first fix the lens body 6 to be tested. Place the lens body 6 inside the fixing ring 5, rotate the screw 17, and the screw 17 drives the arc plate 19 to rotate, bringing it closer to the lens body 6 and clamping it in place to prevent it from falling off during rotation. When the lens body 6 needs to be adjusted, pull the slide rod 8 outward. The slide rod 8 slides inside the connecting plate 7, compressing the spring 10 and causing the positioning rod 11 to disengage from the positioning hole 15. Rotate the adjusting rod 4. At this time… Adjusting rod 4 drives scale rod 21 to slide on the outer surface of angle scale 20, rotating lens body 6 to a suitable angle. Release slide rod 8, spring 10 resets, slide rod 8 slides again inside connecting plate 7, and positioning rod 11 is inserted into the corresponding positioning hole 15 to fix lens body 6 after angle adjustment. When the height of lens body 6 needs to be adjusted, hydraulic rod 12 is activated, hydraulic rod 12 drives slide plate 3 to move up and down, so that slide plate 3 slides on the inner wall of slide groove 13. Then, use testing equipment to test lens body 6.
