Lens module assembling test device and assembling test method

Abstract

The invention relates to an assembly test device and an assembly test method for a lens module. The assembly test device for lens module comprises an assembly device and a torque test unit. The assembly device comprises a centering unit, a fixing unit and a first driver element to drive the turning of the fixing unit to screw drawtubes so as to assemble the lens module, a control unit for transmitting a control signal to control the rotation of the first driver element so that the height of the lens module reaches the default height along the direction of the optical axis thereof; and a laser distance measuring unit for testing whether the height of lens module reaches the default height along the direction of the optical axis thereof. The torque measuring unit is used to measure the torque between the base and the drawtubes. The assembly test device for lens module can achieve a good imaging effect through the lens module and precisely test whether the torque between the base and the drawtubes of the lens module is suitable.

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...
