A lens test focusing machine

Abstract

The invention discloses and provides a lens testing focusing machine, which has high automatic degree, high testing accuracy and high working efficiency. The lens testing focusing machine comprises a frame (1), a lamp box (2), a focusing plate, a light distribution lamp (3), a reference plate (4) and a peripheral host, wherein the reference plate (4) is provided with a swinging platform (5), an X-axis focusing workbench and Y-axis testing workbench; two lens trays are arranged at opposite angles on the swinging platform; the X-axis focusing workbench is driven by an X-axis cylinder to move in the X-axis direction in a reciprocating way; the X-axis focusing workbench is provided with a focusing ring (10); the focusing ring (10) is driven by a focusing motor arranged on the X-axis focusing workbench to rotate; the focusing ring (10) is arranged on a support cylinder; the Y-axis testing workbench is provided with a white screen (12); and the lens trays are provided with sensors. The lens testing focusing machine can be widely applied to the field of lens processing.

Description

technical field [0001] The invention relates to a lens test focusing machine. Background technique [0002] Lenses are used in more and more electronic products, such as mobile phones, cameras, video cameras, etc. After the lens is manufactured, the lens needs to be tested and focussed. During the testing process, it is necessary to test whether there are dead pixels in the manufactured lens, and whether the lens with dead pixels falls within the acceptable range. The existing testing machine or focusing machine intelligently performs testing or focusing in a single way. If the lens needs to be continued to focus after testing, the lens needs to be moved from the testing machine to the focusing machine. This not only wastes a lot of time, but also causes low work efficiency, and the positioning deviation of the lens may occur when the working machine is changed, and it may also cause the lens to be scrapped during the transfer process. In addition to the above deficiencie...

Problems solved by technology

The existing testing machine or focusing machine intelligently performs testing or focusing in a single way. If the lens needs to be continued to focus after testing, the lens needs to be moved from the testing machine to the focusing machine.

This not only wastes a lot of time, but also reduces work efficiency, and may cause positioning deviation of the lens when changing the working machine, and may also cause the lens to be scrapped due to scratches during the transfer process.

In addition to the above deficiencies, the size of the lens tested by the existing testing machine is above 8mm, and the lens size smaller than 8mm is mainly read by manual testing, and its testing efficiency and testing accuracy are low.

The existing focusing has the following defects due to technical limitations: the focusing ring is driven by a servo motor, which greatly increases the cost, makes the focusing machine itself expensive, and indirectly increases the cost of lens focusing; the servo motor and The focus ring is driven by the synchronous pulley and the synchronous belt, which takes up a lot of space, which affects the viewing angle of the lens during focusing and affects the focusing result
