Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, and more specifically to an optical lens positioning device. Background Art

[0002] Optical glass is 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. The existing optical lens processing equipment cannot adjust the fixed optical lens, resulting in a limited positioning distance of the optical lens, which cannot be fully applied to optical lens processing, causing quality problems in optical lens processing.

[0003] For example, the Chinese utility model with application number 202320583372.6 proposes an optical lens positioning device. The patent first places the optical lens between the positioning rings, pushes the connecting plate to the left through the electric telescopic rod, the connecting plate pushes the first connecting rod to deflect, the first connecting rod pushes the second connecting rod to deflect, and the second connecting rod drives the positioning ring on the connecting block to move toward the optical lens until the outer wall of the positioning ring is fit and fixed to the optical lens, and then uses the screw nut on the reciprocating screw to drive the rack to move downward, thereby moving the positioning ring downward. However, the patent can only position a single lens, and the processing efficiency is low.

First, the lens is placed in the placement groove 2, and then the rotating column 4 is pressed downward, and the upper transmission plate 12 and the lower transmission plate 13 are meshed and connected by squeezing the first spring 11, and then the rotating column 4 is rotated counterclockwise, so that the rotating column 4 drives the fixed column to rotate counterclockwise, and then drives the rotating layer 8 to rotate counterclockwise, so that the adjusting block 3 moves toward the fixed block 7 until the lens is fixed. At the same time, the rotating layer 8 drives the ratchet 14 to rotate counterclockwise, and the ratchet 15 can prevent the ratchet 14 from rotating in the opposite direction, and then release the rotating column 4, and the first limit block 10 is driven by the reaction force of the spring to reset the rotating column 4; when the lens needs to be taken out, the reset column 5 is pressed downward to disengage the ratchet 15 from the ratchet 14, and then the rotating column 4 is pressed downward, and the fixed column is driven to rotate clockwise through the rotating column 4, so that the rotating layer 8 rotates clockwise, and then the adjusting block 3 moves outside the fixed block 7, thereby taking out the lens.

[0023] In the embodiment of the utility model, there are multiple fixed blocks 7 and adjusting blocks 3, and the number is the same. The adjusting block 3 and the fixed block 7 together form a circular shape, and the diameter of the adjusting block 3 is smaller than the diameter of the fixed block 7. The bottom end of the first fixed column 6 is fixedly connected to the rotating layer 8, and a groove is provided in the first fixed column 6.

The lens can be fixed by providing the adjusting block 3 and the fixed block 7.

[0024] When in use, first put the lens into the placement groove 2, then press the rotating column 4 downward to make the upper transmission plate 12 and the lower transmission plate 13 meshingly connected, then rotate the rotating column 4 counterclockwise, so that the rotating column 4 drives the fixed column to rotate counterclockwise, and then drives the rotating layer 8 to rotate counterclockwise, so that the adjusting block 3 moves into the fixed block 7 until the lens is fixed.

The ratchet 14 and the pawl 15 can fix the rotating layer 8 to prevent the lens from shaking during processing.

[0028] When the rotating layer 8 rotates counterclockwise, the pawl 15 will slide over the ratchet teeth on the surface of the ratchet wheel 14, thereby not affecting the rotation of the ratchet wheel 14. When the ratchet wheel 14 is about to rotate in the opposite direction, the pawl 15 will be embedded in the ratchet teeth on the surface of the ratchet wheel 14, thereby preventing the ratchet wheel 14 from rotating.
