Description

Technical Field

[0001] The utility model relates to the technical field of lens detection, in particular to an optical lens testing platform. Background Art

[0002] During the optical lens inspection process, the optical lens needs to be moved closer to each other by rotating the screws on both sides respectively. After the optical lens is clamped, light is emitted from one side of the optical lens. After passing through the optical lens, the light enters the photoelectric sensor, which senses the light intensity. The performance of the optical lens is tested according to the intensity of the incident light. Subsequently, the optical lens needs to be heated at different temperatures to test the high temperature resistance of the optical lens.

[0003] During the inspection process, the existing optical lens testing platform needs to conduct high and low temperature tests on the performance and reliability of the lens under different temperature conditions, but the existing device cannot cool the lens, so the lens needs to be left standing to cool, resulting in reduced equipment inspection efficiency. At the same time, when the equipment is in use, the optical lens is placed on the inner wall of the test tray for testing, so that the test tray cannot be replaced according to lenses of different sizes, resulting in a reduced range of use of the equipment.
