Measuring mechanism for light lens processing

Abstract

The invention relates to the technical field of lens measurement, in particular to a measuring mechanism for light lens processing, which comprises a base, a frame fixedly mounted at the upper end of the base and a conveying belt movably arranged on the outer surface of the frame, and two symmetrical guide plates are arranged on the upper surface of the conveying belt through a bidirectional telescopic mechanism. The front end of each guide plate extends to form an arc-shaped plate adaptive to the front end of the conveying belt, a plurality of poke rods are arranged on the two sides of each guide plate in a synchronous transmission mode through a synchronous wheel mechanism, and only the lower ends of the poke rods located on one side of each guide plate are kept to make contact with the surface of the conveying belt. The lens thickness measuring device can be applied to a conveying line, it is guaranteed that continuous conveying of lenses is not affected, the thickness of the lenses is continuously measured, the lenses do not need to be manually arranged in the measuring process, the measuring efficiency is greatly improved, and the continuity of the whole conveying line is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of lens measurement, in particular to a measurement mechanism used for optical lens processing. Background technique [0002] The surface of the sunshade mirror has a certain curvature. In the processing of light lenses such as sunshade mirrors, the resin raw material is melted and injected into the mold and then stamped. After polishing and cleaning, before the final packaging, the thickness of the lens needs to be checked by the staff. Strict control. It is a common way for workers to measure the thickness through a caliper meter. The thickness of the lens is obtained by reading the pointer on the dial. However, this method is very inconvenient and inefficient in actual operation. Measurement and investigation one by one; in order to improve efficiency, sampling surveys are conducted in batches in the existing measurement to improve efficiency, but this method cannot check each lens, so that the th...

[0002] The surface of the sun visor has a certain curvature. In the processing of light lenses such as sun visors, the resin raw material is melted and injected into the mould, and then stamped. After polishing and cleaning, before the final packaging, the staff needs to check the thickness of the lens. Strict control, it is a common way for workers to measure the thickness with a caliper meter, and get the thickness of the lens through the reading of the pointer on the dial, but this method is very inconvenient and inefficient in actual operation, and can only be carried out on the lens one by one Measure and check one by one; in order to improve efficiency, in the existing measurement, sampling surveys are carried out in batches and spot checks to improve efficiency, but this method cannot be used to check every lens, so that the thickness of the obtained lenses cannot be determined. Comprehensive grasp, difficult to improve quality control
