Abstract
The invention relates to automatic detection equipment for an optical module. The equipment comprises an operation robot, an angle positioning camera, a detection device, a controller and a scatteringprojection board, wherein the controller is used for controlling the operation robot, the angle positioning camera and the detection device; the scattering projection board is located on a light pathof the optical module; the operation robot is used for carrying out pose adjustment on the optical module under the assistance of the angle positioning camera; the detection device is used for detecting the optical performance of the optical module. According to the invention, the feeding, discharging, angle correction, positioning testing and the like of the optical module are achieved by adopting the angle positioning camera and the operation robot, inaccurate position, low efficiency and the like of manual operation are avoided, artificial pollution to the optical module is avoided, and the testing precision is guaranteed. The scattering projection board is adopted, and the height of the projection board can be adjusted according to test requirements, so that the quality test of a speckle pattern is enabled to be more accurate, and the size of the whole equipment is reduced at the same time.
Description
technical field [0001] The invention relates to the field of optical detection of optical modules, in particular to an automatic detection device for optical modules. Background technique [0002] Optical modules are widely used in mobile phones, robots, and various intelligent vision hardware markets, including infrared modules, RGB modules, and projection modules. These optical modules must go through a series of strict performance tests before they are put into the market, such as testing the optical power, wavelength, and speckle quality of the infrared structured light projection module. mod. [0003] However, in the prior art, there are few records about optical detection equipment for testing optical power, wavelength, speckle quality, etc., and it is still relatively lacking in automation. Manual loading and unloading and product sorting are required, which is likely to cause human errors. At the same time, Fixing the optical module to be tested on the fixture is a...
