Description

Technical Field

[0001] The utility model is applied to the technical field of camera testing, and particularly relates to a camera positioning testing device. Background Art

[0002] A B2B connector refers to a board-to-board connector; a Nest module is a B2B positioning structure; an 8UP refers to an 8-channel structure; and a pitch refers to the center-to-center distance between the gold fingers on the B2B connector and the center-to-center distance between multiple B2B connectors. Cameras are crucial components in mobile phones and are tested before they leave the factory. The cameras are loaded onto a tray, which mates with a probe module. The cameras output electrical signals through the B2B connector, which is then transmitted to an external tester via the probe module. However, existing techniques often suffer from misalignment between the tray and the probe module, making camera loading inefficient. Manually placing each camera group into its corresponding mounting slot, placing a pressure plate above the cameras, and then tightening the pressure plate with screws is cumbersome and unsuitable for high-volume testing. Furthermore, the B2B connector and lens are often oriented in the same direction, making it easy to scratch or crush the lens during the downward pressure of the B2B connector. Therefore, it is necessary to provide a camera positioning test device with a simple structure, high positioning accuracy, high loading efficiency, and an eccentric arrangement of the B2B connector and the lens.
