Description

Technical Field

[0001] The invention relates to the technical field of optical lens processing equipment, and in particular to a centering tool used for an optical lens finished product detector. Background Art

[0002] Optical lenses are made of high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc. mixed according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasound to remove bubbles, and then cooled slowly over a long period of time to prevent internal stress in the glass block. The cooled glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to become optical lens blanks. Optical lenses need to be fixed during the processing process. General optical lens clamping tools can only clamp lenses of a single size, with a narrow range of adaptability, which greatly increases the purchase and production costs.

[0003] Announcement No. CN 209035751 U discloses a laser marking positioning tool for optical lenses. Since the inner wall of the clamping groove for the upper surface of the lens to contact extends downward along the direction close to the clamping arm, the opening of the clamping groove is set to be constricted, so that lenses of different thicknesses can be adapted, and the rubber pad on the inner wall of the clamping groove can compensate for the gap generated when the lens is fixed, and it is not easy to cause wear to the lens; the clamping arm is driven by the driving component to be telescopic, so that lenses of different sizes can be adapted for clamping, and the piston rod of the driving cylinder is telescopic to drive the clamping arm to slide along the connecting hole, so as to adjust the position of the clamping arm, and lenses of different sizes can be adapted for clamping. However, the patent still has the following problems in actual use:

[0004] Although the laser marking positioning tooling for optical lenses can achieve the clamping and fixing of optical lenses, when clamping and fixing convex or concave optical lenses, it can only clamp and fix the outer side of the optical lens. When the outer side of the optical lens needs to be inspected or processed, the central part of the optical mirror surface cannot be clamped and centered, thereby affecting the inspection or processing of the optical lens.

[0005] A centering tool for an optical lens finished product tester is proposed to solve the above-mentioned problems. Summary of the invention

The characteristics of the meshing connection between the rotating worm and the rotating worm wheel are used to realize the rotation of the fixed chassis, and the detector body is used to realize uninterrupted optical lens testing. The specific contents are as follows:

[0022] 1. By setting a centering clamping mechanism, not only can the optical lens be supported by the connecting support block and the support ring, but also the centering lifting plate can be squeezed downward. Under the action of the first rotating support, the centering rotating rod and the second rotating support, the centering rotating rod is rotated inwardly and the centering sliding sleeve is mobilized to squeeze the sliding spring, so that the centering arc plate is brought closer to the center position of the centering lifting plate, and the centering roller is used to clamp and limit the four sides of the optical lens, and the torsion spring inside the torsion spring rotating sleeve is used to drive the roller bracket and the centering roller to rotate, which can adapt to optical lenses of different sizes, so as to clamp and center the optical lens on the top of the support ring. When the optical lens is moved to the center position, the optical lens is squeezed downward to make the support ring drop to the bottom of the fixed suction cup, and the fixed suction cup is squeezed to make the air of the fixed suction cup squeeze the sealing piston at the top of the exhaust pipe. When the sealing piston moves to the bottom of the exhaust groove, part of the air inside the fixed suction cup can be discharged, and the second support The elastic force of the spring causes the sealing piston to engage with the exhaust pipe, thereby sealing the top of the exhaust pipe, and can generate a certain suction force on the fixed suction cup, thereby fixing the centered optical lens. By setting multiple fixed suction cups and cooperating with the adaptive rotating ball and the spherical rotating sleeve, it can adapt to convex or concave optical lenses, and can adapt to optical lenses of different sizes, so as to facilitate the centering of optical lenses of different sizes before testing. When the optical lens needs to be removed, the optical lens can be pressed down continuously to make it contact with the exhaust support block on the top of the exhaust connecting rod, and the sealing piston can be driven down through the exhaust connecting rod and the exhaust support block, so as to inject air into the interior of the fixed suction cup through the exhaust groove, so that the suction cup loses its adsorption force, thereby removing the optical lens.
