The invention relates to a lens module assembly test device and an assembly test method. The lens module assembling and testing device includes an assembling device and a torque testing unit. The assembly device includes a centering unit; a holding unit; a first excitation unit for driving the holding unit to rotate so that the mirror base and the lens barrel are screwed together to assemble a lens module; a The first excitation arm can align the lens base with the lens barrel; a control unit is used to send a control signal to control the rotation of the first excitation unit, so that the height of the lens module along its optical axis reaches a predetermined height ; and a laser ranging unit for detecting whether the height of the lens module along its optical axis reaches a predetermined height. The torque test unit is used to measure the torque between the mirror base and the lens barrel; a second excitation arm can drive the torque tester to move to the position of the centering unit.
Description
technical field [0001] The invention relates to a lens module assembly test device and an assembly test method, which are used to make the lens base and the lens barrel containing the optical elements rotate together to assemble the lens module, and test the lens barrel and the lens module of the lens module. Torque between mirror mounts. Background technique [0002] With the development of camera technology, lens modules are widely used in camera devices for various purposes, and the combination of lens modules with various portable electronic devices such as mobile phones and computers is favored by many consumers. [0003] A lens module generally includes a lens, a lens barrel, a lens holder, a filter, and spacer components for separating the lens and the filter, such as a spacer. External threads are provided on the outer surface of the lens barrel, a receiving hole is defined on the mirror base, and internal threads are provided on the inner wall of the receiving hole...
