Method and apparatus of optical module assembly

An apparatus of optical module assembly, comprising:

• a movement module, an estimated light spot with a minimum size selecting module, an ideal light spot with a minimum size selecting module, an optimal position selecting module, and an alignment module;
• wherein, the movement module, the estimated light spot with a minimum size selecting module, the ideal light spot with a minimum size selecting module, the optimal position selecting module, and the alignment module are connected sequentially;
• and wherein,
• the movement module, configured to control an alignment mechanism clamping a lens to be assembled to move in a set direction by a first movement step when an optical module to be aligned images;
• the estimated light spot with a minimum size selecting module, configured to when the alignment mechanism moves each time, collect light spots imaged by the optical module to be aligned sequentially, and select an estimated light spot with a minimum size from the collected light spots;
• wherein the estimated light spot with the minimum size is a collected light spot with a size less than all sizes of a first number of light spots before the estimated light spot with a minimum size, and less than all sizes of a second number of light spots after the estimated light spot with a minimum size;
• the ideal light spot with a minimum size selecting module, configured to control the alignment mechanism to move by a second movement step, and search for an ideal light spot with a minimum size according to a reduced movement step and the estimated light spot with the minimum size;
• wherein the second movement step is shorter than the first movement step;
• the optimal position selecting module, configured to determine a movement position of the alignment mechanism when the ideal light spot with the minimum size is collected as an optimal position of the alignment mechanism;
• and
• the alignment module, configured to control the alignment mechanism to move to the optimal position to align the lens to be assembled.
