[0002] Optical lenses are lenses made of optical glass. The definition of optical glass is glass with specific requirements for optical properties such as refractive index, dispersion, transmittance, spectral transmittance and light absorption, and with uniform optical properties. It can change the direction of light propagation and the relative spectral distribution of ultraviolet, visible or infrared light. After production, optical lenses must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion meet the specifications. Therefore, an optical lens positioning device is required.

When clamping circular lenses of different sizes, the clamping may be unstable due to the curvature of the clamping blocks, and the arc-shaped clamping blocks cannot clamp square lenses, thereby reducing the applicability of the device. Secondly, the existing optical lens positioning devices place the lenses on a placement table and then clamp them with the clamping blocks, but the clamped lenses cannot be flipped, thereby reducing the use efficiency of the device.

[0024] An optical lens positioning device includes a base 1, with two support plates 101 fixedly installed on the top of the base 1, and the opposite sides of the two support plates 101 are rotatably connected with shafts 102, and the adjacent ends of the two shafts 102 are commonly fixedly connected with a flip plate 2, and the surface of the flip plate 2 is provided with a placement hole 201, and the inside of the flip plate 2 is provided with a connecting groove 202, and two groups of movable rods 203 are movably connected between the placement hole 201 and the connecting groove 202, and one end of the two movable rods 203 is slidably connected with an extrusion plate 206, and the top of the base 1 is provided with a movable groove 104, and the inside of the movable groove 104 is rotatably connected with a bidirectional screw rod 3, and the outer surface of the bidirectional screw rod 3 is slidably connected with two sliders 301.

[0025] Specifically, the other end of the shaft rod 102 on the right side is fixedly connected with a knob 103, and the knob 103 is turned to flip the flip plate 2, thereby adjusting the angle of the lens.

[0026] Specifically, a dual-axis motor 208 is fixedly installed inside the connecting groove 202, and the output shaft of the dual-axis motor 208 is fixedly connected to a one-way screw rod 209, which is rotationally connected to the flip plate 2, and the slide rod 207 is fixedly connected to the flip plate 2, and the inside of the flip plate 2 is fixedly connected to the slide rod 207.

[0027] Specifically, one end of the extrusion plate 206 is slidably connected to the slide bar 207 , and the other end of the extrusion plate 206 is threadedly connected to the one-way screw 209 . The one-way screw 209 rotates, so that the two extrusion plates 206 move relative to each other on the surface of the slide bar 207 .

[0028] Specifically, a clamping roller 204 is fixedly mounted on the other end of the movable rod 203. The clamping roller 204 is a cylindrical structure. A spring 205 is sleeved on one end of the movable rod 203 located inside the connecting groove 202. The clamping roller 204 clamps and fixes the lens, and the spring 205 pushes the movable rod 203 to reset.

[0029] Specifically, the top of the slider 301 is rotatably connected to a connecting rod 302, and the other ends of the two connecting rods 302 are rotatably connected to a placement plate 303. When the two sliders 301 are relatively displaced, the connecting rod 302 is pushed to rotate, and the two connecting rods 302 rotate and lift the placement plate 303 and the lens.

[0030] Specifically, a single-axis motor 304 is fixedly installed at the bottom of the base 1 , and the output shaft of the single-axis motor 304 is fixedly connected to the bidirectional screw rod 3 .

[0031] The working principle of this utility model:

[0032] When in use, first, turn the knob 103 to level the flip plate 2, then place the round or square lens on the placement plate 303. If it is a square lens, the corner of the lens needs to be placed between the two clamping rollers 204, then start the single-axis motor 304 to drive the bidirectional screw 3 to rotate, the rotation of the bidirectional screw 3 causes the two sliders 301 to move relative to each other and push the connecting rod 302 to rotate, the two connecting rods 302 rotate and lift the placement plate 303 and the lens, when the placement plate 303 is raised to the inside of the placement hole 201, start the double-axis motor 208 to drive the unidirectional screw 209 to rotate, so that the two extrusion plates 206 move relative to each other on the surface of the slide rod 207, and then the two extrusion plates 206 squeeze The movable rod 203 is pressed to slide toward the center of the placement hole 201. During the extrusion process, one end of the movable rod 203 will slide inside the extrusion plate 206, and then the lens will be clamped and fixed by the clamping roller 204. Secondly, the single-axis motor 304 is started to drive the bidirectional screw rod 3 to rotate so that the slider 301 drives the placement plate 303 to descend. After the placement plate 303 is reset, the flip plate 2 can be flipped by turning the knob 103 to adjust the angle of the lens. Through the above structure, the stability of clamping and positioning lenses of different sizes is improved, and round or square lenses can be clamped. In the process of clamping and positioning the lens, it is convenient to adjust the flip angle of the lens, thereby improving the applicability and use efficiency of the device.
