Rapid lens size detection jig

Abstract

The invention belongs to the technical field of optical detection and discloses a rapid lens size detection jig which comprises a base, the base is provided with a detection table, the detection tablecomprises a first detection head and a second detection head, the first detection head is arranged on one end of the upper part of the base, and is fixedly connected with the base, and the second detection head is arranged at the other end of the base and is parallel to the first detection head; a first clamping groove is formed in the inner side of the upper end surface of the first detection head, the inner side of the upper end surface of the second detection head is provided with a second clamping groove which corresponds to the first clamping groove in position and is the same with the first clamping groove in structure, the structure size of the second detection head is the same as that of the first detection head, and a to-be-detected lens slides between the first clamping groove and the second clamping groove to judge whether the to-be-detected lens is qualified or not, so that the detection speed of the lens is increased, standard detection is achieved, various problems caused by improper lenses during mass production are avoided, and the cost is fundamentally reduced.

Description

technical field [0001] The invention relates to the technical field of optical detection, in particular to a jig for rapid detection of lens size. Background technique [0002] At present, the structure of the known LED car lights is generally composed of reflectors, lenses and some necessary structures, and the lens is an indispensable part of the LED car lights, and the contact between the lens and the housing is fixed, and its size is relatively large. Car light assembly is very important, too large or too small will affect the quality of the installation, and then affect the focusing effect, and even, if a wrong judgment is made, the entire LED light or several parts connected to the lens will be scrapped, resulting in waste of materials , cost increase and waste of human, material and financial resources. [0003] Existing lens size inspection methods usually use micrometer calipers or dial gauges for detection, but the speed is very slow and the efficiency is not high...

[0002] At present, the structure of the known LED car lights is generally composed of reflectors, lenses and some necessary structures, and the lens is an indispensable part of the LED car lights, and the contact between the lens and the housing is fixed, and its size is relatively large. Car light assembly is very important, too large or too small will affect the quality of the installation, and then affect the focusing effect, and even, if a wrong judgment is made, the entire LED light or several parts connected to the lens will be scrapped, resulting in waste of materials , cost increase and waste of human, material and financial resources

[0003] Existing lens size inspection methods usually use micrometer calipers or dial gauges for detection, but the speed is very slow and the efficiency is not high, and the lens is easily damaged during the measurement process, making the lens unusable, which requires the operator to carefully carry out measurement, while using other methods for measurement, the accuracy cannot be guaranteed
