Abstract

The invention relates to a life test system of a voice coil motor to solve the problems of long time consumption and high cost in the life test of the voice coil motor in the prior art. The voice coil motor life testing system of the present invention includes: a controller, and a test main board, a test board and an installation device for locking the voice coil motor to be tested in sequence; The driver chip of the current; the mounting device has a conductive mechanism that conducts or disconnects the driver chip and the voice coil motor to be tested; the test main board is used to supply power to the driver chip on the test board and Converting the life test command sent by the controller into an instruction recognizable by the driver chip on the test board, the driver chip is used to output a current of a specific size according to the instruction, and transmit it to the driver chip through the conductive mechanism The voice coil motor to be tested is used to perform a life test on the voice coil motor to be tested.

Description

technical field [0001] The invention relates to the field of voice coil motor testing, in particular to a voice coil motor life testing system. Background technique [0002] As consumers have higher and higher requirements for the quality of photos and videos, mobile phones and tablet computers have unique advantages of portability. Screen and important information, so that the camera of mobile phone and tablet computer is turned on and off very frequently. According to the statistics of an IT expert, some consumers may turn on and off the camera nearly 100 times a day. When the mobile phone frequently starts the camera, the requirements for the voice coil motor parts are very high. It is necessary to use the voice coil motor to capture the object to the clearest, and to evaluate the number of operations at least hundreds of thousands of times to ensure the long-term stability of the mobile phone camera parts. [0003] At present, most voice coil motor life tests on the mar...
