Technical Field
The present invention relates to a lens quality detection device and system thereof, and more particularly to a lens quality detection device and system thereof capable of greatly improving detection convenience and preventing damage caused by collision of a pattern generation device.
Background
As the size of the lens module is gradually reduced, the conventional lens tester encounters a detection bottleneck during testing. Referring to fig. 1, which is a conventional lens quality inspection system 1, a back focal length of a wafer-level lens module 10 is shorter than that of a conventional lens module, and the size of the wafer-level lens module is much smaller than that of the conventional lens module, so that when a conventional lens tester 11 performs an optical test on the wafer-level lens module 10, a protrusion 120 of a pattern generator 12 needs to enter a through hole 13 to project a pattern beam 14, which is likely to cause damage to the pattern generator 12 due to the pattern generator 12 colliding with left and right sides of the lens tester 11.
In addition, if the next lens module 10 to be tested needs to be tested, the lens testing machine 11 is moved away from the pattern generating device 12 and then the head testing machine 11 is moved horizontally until the next lens module 10 to be tested is tested, so two actions are generated during the testing process, which takes a relatively long testing time and is inconvenient for the testing process. Therefore, how to solve the above conventional problems and deficiencies is one of the ways in which the authors and related manufacturers in this industry desire to research and improve.
