Abstract

The invention relates to the technical field of flat sheet surface defect detection and in particular discloses a solar backboard detection system. Line sources and photographing cameras are arranged on the front surface and the back surface of a solar backboard to synchronously detect the surface defects on the front surface and the back surface of the solar backboard; the distances S1 from the lenses of the cameras to photographing regions are 420-430mm, the photographing angles alpha of the lenses of the cameras relative to the solar backboard plane are 16-18 degrees, the distances S2 from the line sources to irradiating regions are 78-80mm, and the included angles beta between the light of the line sources and the solar backboard plane are 35-39 degrees. Multiple threshold values can be adjusted while the surface defects on the front surface and the back surface of the solar battery are precisely detected, so that one piece of equipment can meet detection of different products. The detection system replaces a conventional manual detection mode and has the advantages of being high in detection precision, uniform in detection standard, high in detection efficiency and low in manual cost.

Description

technical field [0001] The invention relates to the technical field of surface defect detection of planar sheets, in particular to a solar backboard detection system. Background technique [0002] The solar backsheet is located on the back of the solar panel, which protects and supports the battery sheet, and has reliable insulation, water resistance and aging resistance. In the production process of the solar backsheet, defects such as missing coating, roller marks, and rough lines may occur due to poor coating, and there may also be defects such as mosquitoes, dirt and foreign objects, and fish scale lines and orange peel lines may also occur due to poor raw materials. , scratches, pinholes and other defects. [0003] Therefore, after the solar backplane is finished, it needs to be strictly inspected for surface defects to ensure the quality. The existing detection method, the whole process is carried out manually, the detection efficiency is low, the missed detection ra...
