Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a lens surface wear-resistance detection device. Background Art

[0002] The main raw material of glass lenses is optical glass. When users take off their glasses and use them, the lenses are inevitably contaminated and covered with dust. Therefore, the lenses need to be wiped frequently, and the wiping process will rub the lenses and cause damage to the mirror surface. Therefore, the wear resistance of the lenses is an important indicator for judging the quality of the lenses. Therefore, it is necessary to perform a wear resistance test on the lens surface.

[0003] Among them, a lens wear resistance testing machine disclosed in application number CN201920765193.8 is also an increasingly mature technology. An exhaust fan is arranged at the bottom of the test slot, and an air inlet is left between the operating table and the side wall of the test slot. When conducting the test, impurities on the operating table enter from the air inlet under the suction force of the exhaust fan, and finally gather in the collection box, which can ensure the cleanliness of the environment during the test and reduce the influence of impurities on the test results.

[0004] Based on this, we agree with the advantages of the above products, but there are still the following defects:

[0005] The wear resistance tester cannot fix lenses of different sizes, and the lens has an arc-shaped structure, so when fixing the lens, only the top can be fixed, which makes it possible for the lens to swing or shake unstably during friction testing. Utility Model Content
