The invention provides a method for assembling camera modules for batch under-screen recognition devices. The method comprises the following steps that 1, taking one of the camera modules for the batch under-screen recognition devices as a reference camera module; Step 2, obtaining a relation curve of an MTF value and a lens screw-in value of the reference camera module; Step 3, obtaining a reference lens screw-in value interval according to the relation curve; and 4, screwing the lens of the camera module for the recognition device under the screen into the corresponding lens carrier, and enabling the lens screwing value to be within the reference lens screwing value interval. The invention provides a method for assembling camera modules for a batch screen recognition device. The method comprises the following steps: firstly, obtaining a relation curve of an MTF value and a lens screw-in value; during assembly, the lens screw-in value is directly controlled to fall into the referencelens screw-in value inter
