The invention discloses a testing device for a camera module group. The testing device includes a connection module, a control module, a channel selection module, a constant current source module, a processing module and a display module. The connection module has base pins which are in one-by-one corresponding connection to stitches of the camera module group; the control module is configured to control gating states of the channel selection module so as to select one base pin of the connection module as a to-be-tested base pin to be connected to a testing earthed terminal and select the other base pin of the connection module as a reference base pin to be connected to a signal output end which provides a voltage signal to the processing module; the constant current source module is configured to output a constant current to the signal output end; the processing module is configured to detect the connecting state between the to-be-tested base pin and the corresponding reference base pin on the basis of the received voltage signal; the display module is configured to display the connecting state. According to the embodiments of the invention, the testing device can automatically detect the connecting state between the to-be-tested base pin and the reference base pin, and increases testing efficiency of the module group.
Description
technical field [0001] The invention relates to the technical field of camera module testing, and more particularly, the invention relates to a testing device for a camera module. Background technique [0002] In the production of camera modules, due to reasons such as FPC, welding and gold wires, there will always be open circuits and short circuits of some pins of the module, or differences in impedance between MIPI signals. After the open and short circuit occurs, it can still start and run normally on the test platform of the camera module, but the camera module cannot run normally on the mobile phone. In the camera module, some image sensors may be damaged, and the diode value of the pins of some image sensors may change abnormally. However, the camera module can often be tested and run normally, and abnormalities will appear after a long period of operation. Such problems will affect the use of the camera module on the client side, and have a huge impact on the image ...
