Abstract: Provided are a method and an apparatus of optical module assembly, where the method includes: when an optical module to be aligned images, controlling an alignment mechanism clamping a lens to be assembled to move in a set direction by a set movement step; when the alignment mechanism moves each time, collecting, by an image acquisition device, light spots imaged by the optical module to be aligned sequentially, and selecting a light spot with a minimum size from the collected light spots; determining an optimal position of the alignment mechanism according to at least two light spots before the light spot with the minimum size and at least two light spots thereafter; and controlling the alignment mechanism to move to the optimal position to align the lens to be assembled.

Abstract: An apparatus and a method for assembling optical module is provided and the method includes: controlling an alignment mechanism holding a to-be-assembled lens to move at a preset step-size in a preset direction when an optical module to be aligned generates an image; collecting light spots of the images generated by an optical module to be aligned sequentially by an image collecting means, each time the alignment mechanism moves; selecting a light spot with a minimum size from the collected light spots, and determining a movement position of the alignment mechanism when the light spot with the minimum size is collected, as an optimal position; controlling the alignment mechanism to move to the optimal position to align the to-be-assembled lens.
