Abstract

A kind of decline test system includes a location controller, an imaging location device to image for the tested piece and measure the tested piece position, a pick-putting device and a controller to control the pick-putting device according to the image result. The controller is connected with the imaging location device, pick-putting device and the location controller electrically. The location controller controlled by the controlling device controls the pick-putting device work. The pick-putting device tests the piece decline in the control of the controlling device and location controller. The decline system can pick and put the tested piece automatically to improve the test speed and efficiency.

Description

technical field

[0001] The present invention relates to a drop test system, in particular to a drop test system and a test method suitable for camera lens modules. Background technique

[0002] With the continuous development of science and technology, portable electronic devices such as mobile phones are widely used and tend to be light, beautiful and multi-functional. The camera function is an additional function of the popular mobile phones in recent years. The digital camera module used in mobile phones must not only meet the requirements of thinness and shortness, but also have high performance and quality. Therefore, after the digital camera lens module is assembled, it must be subjected to a drop test. The main purpose is to It is to test whether the components on the lens module, especially the filter, will fall out of the lens barrel due to the impact of the drop.

[0003] The current drop test system manually fixes the test piece on a solid plastic cuboid, falls f...
