Description

Technical Field

[0001] The utility model relates to the technical field of camera module testing, in particular to a flip ejector module testing device of a camera module. Background Art

[0002] During the production and testing process, mobile phone cameras in the current industry need to be connected to the connector test board and then connected to the tooling for open-diagram testing. Not only mobile phone cameras, but all kinds of modular electronic devices require connector test boards to be connected to tooling for testing. Generally, when camera modules are tested in large quantities in mass production, it is necessary to open the corresponding pneumatic fixture (including ejector module) and test board of the automatic machine. However, the automatic machine uses a robot to grab the module material and then put it into the pneumatic fixture. After the pneumatic fixture is closed, the module connector and the ejector module will be closed and connected, so that the module and the test board are conductive, so that the tooling can be opened for testing.

[0003] For example, a flip-up pin module test board for camera module testing (Announcement No.: CN219179548U) includes a tooling test box with a PCB test board inserted on its surface. The surface of the PCB test board is provided with a flip-up pin module and a camera module. The connection end of the camera module extends to the interior of the flip-up pin module, and the camera module is fixed by the flip-up pin module. The utility model buckles the flip-up pin module onto the test board to replace the original connector test board with a new test board. It combines the pin module in the pneumatic fixture of the automatic machine and the advantages of the connector test board in portability, small size and low cost, thereby improving the problem of connector wear caused during camera module testing and the connector welding problem of the original connector test board, and can maintain the same board specifications as the automatic machine test board, thereby reducing development costs and material costs.

[0004] However, the device still has the following defects:

[0005] When testing the camera module, this device only connects and fixes the connection cables of the camera module, and does not clamp the camera. Without a stable clamping mechanism, the camera module may be displaced or shaken during the test, which will lead to a decrease in the accuracy of the test results. Therefore, we need to propose a flip-top pin module testing device for the camera module. Utility Model Content
