Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, and in particular to an optical lens edging machine. Background Technology

[0002] Optical lenses are lenses that can change the direction of light propagation and alter the relative spectral distribution of ultraviolet, visible, or infrared light. When optical lenses are processed into circular shapes, they need to be ground using an optical centering and edge-grinding device.

[0003] Existing optical centering and edging devices are not convenient for centering optical lenses. If the optical lens is not aligned with the center during the edging process, the edges and corners will be ground unevenly. This is especially true when grinding round optical lenses, where grinding deviation will occur, affecting the quality of the optical lens. Utility Model Content

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes an optical lens edging machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A transmission component is connected between the lifting mechanism and the centering mechanism. When the lifting mechanism drives the elastic upper pressing block to move downward to press the optical lenses, it can simultaneously drive the two centering mechanisms to slide inward relative to each other through the transmission mechanism, and push the optical lenses to keep them confined in the center position of the lower rotating disk.

[0007] In some embodiments, the elastic upper pressure block includes a pressure block and a fixed block disposed above the pressure block. A guide post is provided at the upper end of the pressure block, the guide post is movably inserted through the fixed block, and a spring is sleeved on the guide post. The upper end of the spring abuts against the fixed block, and the lower end abuts against the pressure block.

[0008] In some embodiments, an arched frame is provided on the workbench, and the lifting mechanism includes a first cylinder located at the upper end of the arched frame. The piston rod of the first cylinder is vertically downward and connected to a connecting column. A rotating column is provided at the upper end of the fixed block, and the rotating column is rotatably installed at the lower end of the connecting column.

[0009] In some embodiments, the centering mechanism includes a sliding seat that slides left and right, a V-shaped frame is provided on the side of the sliding seat near the lower rotating disk, and rollers are rotatably mounted at both ends of the V-shaped frame.

[0010] In some embodiments, the transmission assembly includes a first support plate disposed on the connecting column, a second support plate disposed on the upper end of the sliding seat, and a third support plate disposed on the lower side of the arched frame. The third support plate is disposed between the first support plate and the second support plate, and a V-shaped swing frame is hinged to the third support plate. A cylinder is disposed at both ends of the V-shaped swing frame. A transverse slide groove is disposed on the first support plate, and a vertical slide groove is disposed on the second support plate. The cylinder at one end of the V-shaped swing frame is movably disposed in the transverse slide groove, and the cylinder at the other end is movably disposed in the vertical slide groove.

[0011] In some embodiments, a first motor for driving the lower rotary table to rotate is provided at the lower end of the worktable.

[0012] In some embodiments, a second cylinder is provided on the worktable and behind the lower rotary disk, a motor mounting base is slidably provided on the piston rod of the second cylinder, a second motor is provided on the motor mounting base, and a grinding disc is provided on the output shaft of the second motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When performing edge grinding on a lens, the optical lens is placed on the lower rotating disk, and then the elastic upper pressure block is driven to move down through the lifting mechanism and elastically presses the optical lens. While the elastic upper pressure block moves down, it drives the centering mechanisms on the left and right sides to move closer together through the action of the transmission mechanism and pushes the optical lens so that the optical lens is coaxially set with the center of the lower rotating disk. Thus, the optical lens is easy to align with the center during the edge grinding process, and it is less likely to cause grinding deviation during the grinding process, thereby improving the quality of the optical lens.
