The optical lens test lens device is a professional device specifically used to detect, measure and evaluate the performance and quality of optical lenses. It integrates precise mechanical structures, optical components, electronic measurement systems and data processing software, and can perform comprehensive and accurate tests on various optical parameters, physical properties and surface quality of lenses.

[0003] In the optical lens testing device of the prior art, the movement of airflow during the test will drive the movement of dust particles.

Airflow disturbances, airflow disturbances inside or around the device may cause tiny particles on the surface of the optical lens to move. These particles will scatter light, thereby affecting the accuracy of the test.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] like Figures 1-10 As shown, an optical lens testing device according to the present invention comprises a base 100, wherein the upper end of the base 100 is slidably connected to a first sliding block 200 and a second sliding block 203, wherein the upper end of the first sliding block 200 is fixedly connected to a first housing 201, wherein the upper end of the second sliding block 203 is fixedly connected to a second housing 204, wherein a bottom plate 207 is fixedly connected inside the second housing 204, wherein a cover plate 405 is disposed at the upper end of the bottom plate 207, and wherein a fitting member for bringing the first housing 201 and the second housing 204 together is disposed at the upper end of the base 100. Mechanism 300, a covering mechanism 400 for covering a cover plate 405 on the upper end of a bottom plate 207 is arranged inside the second shell 204, a moving mechanism 500 for moving the optical lens to the center position of the bottom plate 207 is arranged inside the bottom plate 207, an arc plate 503 is slidably connected to the upper end of the bottom plate 207, a lamp bead 5032 is arranged inside the arc plate 503, a protection mechanism 600 for protecting the lamp bead 5032 is arranged on the surface of the arc plate 503, and an exhaust mechanism 700 for evacuating a vacuum between the cover plate 405 and the bottom plate 207 is arranged on the upper end of the bottom plate 207.

[0021] Specifically, a first sliding rod 202 is slidably connected inside the first sliding block 200. A second sliding block 203 is slidably connected to the surface of the first sliding rod 202. The upper end of the second sliding block 203 is fixedly connected to a second outer shell 204. An opening 2041 is formed inside the second outer shell 204. One end of the second sliding block 203 is fixedly connected to a first connecting pipe 208. A detector 205 is provided at each of the upper and lower ends of the inner surface of the first outer shell 201. A first spring 206 is sleeved outside the first sliding rod 202. One end of the first spring 206 is fixedly connected to the base 100, and the other end of the first spring 206 is fixedly connected to the second sliding block 203.

[0022] In addition, the fitting mechanism 300 includes a hydraulic cylinder 301. The non-output end of the hydraulic cylinder 301 is installed at the upper end of the base 100. The output end of the hydraulic cylinder 301 is fixedly connected to a first steel wire rope 302. A first rotating pin 303 is attached to the surface of the first steel wire rope 302. One end of the first steel wire rope 302 is fixedly connected to a piston 304. One end of the piston 304 is fixedly connected to a second spring 305. One end of the second spring 305 is fixedly connected to the second sliding block 203. When in use, an optical lens is placed on the upper end of the bottom plate 207. Before detecting the optical lens, the hydraulic cylinder 301 is started to move away from the first outer shell 201. When the hydraulic cylinder 301 moves in one direction, it will drive the first steel wire rope 302 to move in one direction. After the first steel wire rope 302 moves in one direction and is redirected by the first rotating pin 303, the first steel wire rope 302 will drive the piston 304 to move towards the first outer shell 201. When the piston 304 moves in one direction, it will drive the second sliding block 203 to move in one direction. When the second sliding block 203 moves in one direction, it will pull the first spring 206. When the second sliding block 203 moves in one direction, it will drive the second outer shell 204 to fit the first outer shell 201. When the second outer shell 204 fits the first outer shell 201, a closed space will be formed. The second outer shell 204 and the first outer shell 201 are made of glass material, which is convenient for observation and the entry of light. Subsequently, the two detectors 205 provided inside the first outer shell 201 are used to test the optical lens.

[0023] Further, the covering mechanism 400 includes an elastic cord 401. One end of the elastic cord 401 is fixedly connected to the base 100. A first sleeve 404 is slidably connected to the surface of the elastic cord 401. A second rotating pin 402 is attached to the surface of the elastic cord 401. Both ends of the second rotating pin 402 are rotatably connected to the first sleeve 404. A second connecting pipe 403 is slidably connected to the inside of the first sleeve 404. The second connecting pipe 403 is slidably connected to the opening 2041. A third spring 406 is fixedly connected to the lower end of the second connecting pipe 403. The lower end of the first sleeve 404 is fixedly connected to the first connecting pipe 208. One end of the second connecting pipe 403 is fixedly connected to a cover plate 405. When the second sliding block 203 moves towards one end, it will move away from the elastic cord 401. At this time, the elastic cord 401 will pull the second connecting pipe 403 downward. The downward movement of the second connecting pipe 403 will compress the third spring 406. The downward movement of the second connecting pipe 403 will drive the cover plate 405 to move downward. The downward movement of the cover plate 405 will cover the upper end of the bottom plate 207. Both the cover plate 405 and the bottom plate 207 are made of glass. When the cover plate 405 covers the upper end of the bottom plate 207, it will seal the internal optical lens. The sealing between the cover plate 405 and the bottom plate 207 can prevent the influence of external gas flow on the detection result.

[0024] It should be noted that the toggle mechanism 500 includes a second sleeve 501, the lower end of the second sleeve 501 is elastically connected to the bottom plate 207 through a torsion spring, a guide groove 5011 is provided inside the second sleeve 501, a second sliding rod 502 is elastically connected inside the second sleeve 501 through a compression spring, a round rod 504 is fixedly connected to the lower end surface of the second sliding rod 502, the round rod 504 is slidably connected to the guide groove 5011, an arc plate 503 is fixedly connected to the surface of the second sleeve 501, a hollow groove 5031 is provided inside the arc plate 503, and a lamp bead 5032 is fixedly connected inside the hollow groove 5031; in the optical lens testing device, it is necessary to ensure that the tested lens is strictly centered with the test light path, which is a key prerequisite for ensuring the test accuracy. When the cover plate 405 moves downward, it will drive the second sliding rod 502 to move The second sleeve 501 is rotated by the second sliding rod 502, and the second sliding rod 502 is rotated by the second sliding rod 502. The second sliding rod 502 ... compressed in the second sleeve 501. The compression spring inside the second sleeve 501 drives the second sleeve 501 to rotate, and the second sleeve 501 compresses the spring between the second sleeve 501 and the bottom plate 207. The rotation of the second sleeve 501 drives the arc plate 503 to rotate. The spring steel material inside the arc plate 503 has a certain elasticity, and the outer surface of the arc plate 503 is made of rubber. The rotation of the arc plate 503 will move the optical lens and move the optical lens to the center position of the bottom plate 207. At the same time, the arc plate 503 has a certain elasticity, and the surface of the arc plate 503 is made of rubber, so that the arc plate 503 pushes the optical lens gently, and will not cause damage to the optical lens in the process of moving the optical lens.

[0025] Specifically, the protection mechanism 600 includes a third sliding rod 601. The third sliding rod 601 is elastically connected to the arc-shaped plate 503 through a compression spring. One end of the third sliding rod 601 is fixedly connected with a baffle 602, and the baffle 602 is in contact with the arc-shaped plate 503. When the cover plate 405 moves downward, it will also drive the third sliding rod 601 to move downward. The downward movement of the third sliding rod 601 will drive the baffle 602 to move downward. The downward movement of the baffle 602 will move away from the hollow groove 5031. At this time, the light generated by the lamp bead 5032 will shine on the surface of the optical lens. When the cover plate 405 moves upward, the baffle 602 will cover the hollow groove 5031 to prevent external dust and impurities from adhering to the surface of the lamp bead 5032. Dust will cause light scattering, and the originally direct light will become "scattered like a celestial maiden scattering flowers", resulting in uneven light distribution and a larger brightness difference between the edge and the center of the lens during testing. By setting the baffle 602, when the cover plate 405 covers the bottom plate 207, the baffle 602 will move away from the hollow groove 5031. At this time, the light generated by the lamp bead 5032 will shine on the surface of the optical lens. When the cover plate 405 is opened, the baffle 602 will cover the hollow groove 5031 to prevent external dust and impurities from adhering to the surface of the lamp bead 5032.

[0026] It is worth mentioning that the air extraction mechanism 700 includes an air suction pipe 701. The upper end of the air suction pipe 701 is fixedly connected with the cover plate 405. After the cover plate 405 covers the upper end of the bottom plate 207, at this time, the first steel wire rope 302 will pull the piston 304 to compress the second spring 305. The movement of the piston 304 away from the first connecting pipe 208 will generate negative pressure inside the second sliding block 203. When negative pressure is generated inside the second sliding block 203, air is extracted between the cover plate 405 and the bottom plate 207 through the first connecting pipe 208, the first sleeve 404, the second connecting pipe 403, the cover plate 405, and the air suction pipe 701. The cover plate 405 is provided with through holes around it to connect the second connecting pipe 403 and the air suction pipe 701, which will not affect the transparency of the center position of the cover plate 405. The space between the cover plate 405 and the bottom plate 207 is evacuated to create a sealed vacuum environment that provides a non-interfering, highly controllable, and highly reproducible condition for the optical lens test, improving the test accuracy. At this time, the optical lens is located between the cover plate 405 and the bottom plate 207, and the cover plate 405 and the bottom plate 207 are located between two detectors 205. The two detectors 205 detect the upper and lower surfaces of the optical lens through the cover plate 405 and the bottom plate 207. By setting the air suction pipe 701 between the cover plate 405 and the bottom plate 207, the space between the cover plate 405 and the bottom plate 207 is evacuated after the cover plate 405 covers the upper end of the bottom plate 207, improving the test accuracy.

[0027] A method for testing an optical lens, applicable to the optical lens testing device, specifically comprising the following steps: placing an optical lens on the upper end of a bottom plate 207, before testing the optical lens, starting a hydraulic cylinder 301 to move toward an end away from a first housing 201, the hydraulic cylinder 301 moving toward one end will drive a first steel wire rope 302 to move toward one end, the first steel wire rope 302 moving toward one end through the reversal of a first rotating pin 303, the first steel wire rope 302 will drive a piston 304 to move toward an end close to the first housing 201, the piston 304 moves toward the first housing 201, and the piston 304 moves toward the first housing 201. The movement of one end will drive the second sliding block 203 to move toward one end, and the movement of the second sliding block 203 to one end will pull the first spring 206. The movement of the second sliding block 203 to one end will drive the second shell 204 to fit the first shell 201. The second shell 204 fits the first shell 201 to form a closed space, which has the function of dustproof and blocking airflow. The second shell 204 and the first shell 201 are made of glass, which is convenient for observation and light entry. The optical lens is subsequently tested through two detectors 205 set inside the first shell 201.

[0028] When the second sliding block 203 moves toward one end close to the first shell 201, it will move away from the elastic rope 401. At this time, the elastic rope 401 will pull the second connecting tube 403 downward to move downward. The downward movement of the second connecting tube 403 will compress the third spring 406. The downward movement of the second connecting tube 403 will drive the cover 405 to move downward. The downward movement of the cover 405 will cover the upper end of the bottom plate 207. Both the cover 405 and the bottom plate 207 are made of glass. The cover 405 covering the upper end of the bottom plate 207 will seal the internal optical lens. The cover 405 is sealed between the bottom plate 207 to prevent the influence of external gas flow on the detection result.

[0029] In the optical lens testing device, the tested lens and the testing optical path need to be centered, which is a key prerequisite for ensuring the test accuracy. When the cover plate 405 moves downward, the second sliding rod 502 will be driven to move downward, and the second sliding rod 502 will be driven to move downward. The second sliding rod 502 will be driven to move downward, and the second sliding rod 502 will be driven to move downward. The downward movement of the second sliding rod 502 will compress the compression spring inside the second sleeve 501, and the round rod 504 will be driven to rotate in the guide groove 5011, and the second sleeve 501 will compress the second sleeve 501 and the bottom plate 207. The spring between the second sleeve 501 and the second sleeve 501 rotates to drive the arc plate 503 to rotate. The spring steel material inside the arc plate 503 has a certain elasticity, and the outer surface of the arc plate 503 is made of rubber. The rotation of the arc plate 503 will push the optical lens to the center position of the bottom plate 207. At the same time, the arc plate 503 has a certain elasticity, and the surface of the arc plate 503 is made of rubber material, which makes the arc plate 503 push the optical lens gently, and will not cause damage to the optical lens in the process of pushing the optical lens.

[0030] While the cover plate 405 moves downward, it will also drive the third sliding rod 601 to move downward. The downward movement of the third sliding rod 601 will drive the baffle 602 to move downward. The downward movement of the baffle 602 will move away from the hollow groove 5031. At this time, the light generated by the lamp bead 5032 will shine on the surface of the optical lens. The lamp bead 5032 can provide light, enabling the optical lens test lens device to be used normally even in a dim or lightless environment. When the cover plate 405 moves upward, the baffle 602 will cover the hollow groove 5031 to prevent external dust and impurities from adhering to the surface of the lamp bead 5032. Dust will cause light scattering, and the originally direct light will become "like a shower of flowers", resulting in uneven light distribution and a larger brightness difference between the edge and the center of the lens during testing. By setting the baffle 602, when the cover plate 405 covers the bottom plate 207, the baffle 602 will move away from the hollow groove 5031. At this time, the light generated by the lamp bead 5032 will shine on the surface of the optical lens. When the cover plate 405 is opened, the baffle 602 will cover the hollow groove 5031 to prevent external dust and impurities from adhering to the surface of the lamp bead 5032.

[0031] After the cover plate 405 covers the upper end of the bottom plate 207, at this time, the first steel wire rope 302 will pull the piston 304 to compress the second spring 305. The movement of the piston 304 away from the first connecting pipe 208 will generate negative pressure inside the second sliding block 203. The generation of negative pressure inside the second sliding block 203 will evacuate the space between the cover plate 405 and the bottom plate 207 through the first connecting pipe 208, the first sleeve 404, the second connecting pipe 403, the cover plate 405, and the suction pipe 701. The cover plate 405 is provided with through holes around it to connect the second connecting pipe 403 and the suction pipe 701, which will not affect the transparency of the center position of the cover plate 405. Evacuating the space between the cover plate 405 and the bottom plate 207 creates a sealed vacuum environment that provides interference-free, highly controllable, and highly reproducible conditions for the optical lens test, improving the test accuracy. At this time, the optical lens is located between the cover plate 405 and the bottom plate 207, and the cover plate 405 and the bottom plate 207 are located between two detectors 205.
