Abstract
The invention relates to the technical field of display screen manufacturing, and provides a testing device and method based on a vehicle-mounted multi-connected screen, the vehicle-mounted multi-connected screen testing device is constructed by designing a main control module and a conveying mechanism, a space positioning structure and an optical testing module which are connected with the main control module, a to-be-tested product is automatically conveyed by utilizing the conveying mechanism, and the production efficiency of the product can be improved; the optical test module can be controlled to be aligned with a to-be-tested product in a test area in space by means of the space moving function of the first motion shaft assembly, and the optical test module can be controlled to expand or reduce the test coverage in the horizontal direction by cooperating with the horizontal moving function of the second motion shaft assembly. Therefore, large-size multi-connected screens of various sizes are adaptively compatible, the equipment compatibility is high, the production line adaptability is high, and the automatic test production line can not only improve the product test efficiency, but also effectively reduce the test cost.
Description
technical field [0001] The invention relates to the technical field of display screen manufacturing, in particular to a test device and method based on a vehicle-mounted multi-screen. Background technique [0002] With the development of intelligent automobiles, on-board displays are also developing in the direction of large-scale connected screens and multi-screens. The display screen represents the value of the smart cockpit. First of all, it must be attractive at first glance, beautiful, high-end, technological, and timely. Process relevant information reasonably. Car factory customers have very strict requirements on the appearance defects and optical performance of multi-screen displays. The production and testing of multi-screens faces contradictions between quality, efficiency, and cost. [0003] At present, in the production and manufacturing of the industry, industrial cameras are mainly used to detect the display appearance defects of vehicle screens, and probe-ty...
