Description

Technical Field

[0001] The utility model relates to the technical field of the base of a camera module, in particular to a base for improving the glue painting precision of a camera module. Background Art

[0002] At present, for the existing ordinary large-lens camera modules, because the lens and the base are large in size, it is very difficult for the suction force of the machine to directly suck them up and carry them. Therefore, the production process is that the operator manually paints glue and carries them. The carrying precision between the base and the board is mainly controlled by the matching degree between the positioning posts of the base and the positioning holes of the board. Their combination depends on glue. The employee first paints glue on the board, and after the glue painting is completed, the base is carried on it. The ordinary glue painting line only uses two positioning holes in the diagonal direction of the board as a reference. Therefore, this will cause the situation that the glue painting line is not straight and accurate enough when the employee paints glue, so that when the base is carried, the base cannot coincide well with the glue, resulting in an unstable combination and the problem of light leakage.
