Description

Technical Field

[0002] In the existing technology, photovoltaic modules need to be tested and screened before they are put into practical use to select qualified products from unqualified products, especially cell testing, which is the most critical. The quality of a cell determines the function of a solar circuit board. At the same time, various components need to be identified and screened before the lamination process and frame assembly process. During the screening process, there are often some omissions or deviations, resulting in high rework rates of cells or modules, low module performance and other problems.

[0003] At present, when conducting EL testing on photovoltaic modules, it is necessary to take pictures of the photovoltaic modules through a camera. However, for different types of photovoltaic modules, the shooting distance of the camera needs to be adjusted accordingly; however, the camera position of the existing camera device is not easy to adjust, and it is not possible to detect different types of optical modules.

[0004] Therefore, it is an urgent problem for those skilled in the art to develop a photovoltaic module testing and photographing device in which the camera position can be adjusted according to the photovoltaic module model. Utility Model Content

[0005] In view of this, the utility model provides a photovoltaic module testing and photographing device, in which the camera position can be adjusted according to the photovoltaic module model.

[0011] A driving assembly, wherein a fixed end of the driving assembly is connected to the fixed frame, and a movable end of the driving assembly is connected to the movable frame.

[0012] The beneficial effect of adopting the above technical solution is that in the utility model, under the drive of the driving component, the mobile frame can drive the camera to move up and down along the fixed frame.

The movement of the moving block and the moving frame can be achieved by rotating the screw rod.

[0014] Preferably, both ends of the screw rod are rotatably connected to a nut seat, and the nut seat is fixedly connected to the fixing frame. The setting of the nut seat makes the connection between the screw rod and the fixing frame more stable.

[0015] Preferably, a slide rail is provided on one side of the fixed frame close to the mobile frame along its height direction, and a slider is provided on one side of the mobile frame close to the fixed frame, and the slider is slidably connected to the slide rail.
