Device for automatically detecting welding state of solar junction box

The utility model discloses a device for automatically detecting the welding state of a solar junction box. Workbench, side plates are symmetrically and fixedly connected to the upper surface of the workbench. A conveying mechanism is mounted on the inner side of the side plate; the conveying mechanism comprises a conveying belt; one end of the conveying belt is rotationally connected with a firstroller. One side of the first roller is rotationally connected with a second roller. Bearings are mounted at the two ends of the second roller; a U-shaped rubber strip is adhered to the surface of the conveying belt; a servo motor is mounted on the outer wall of the side plate; a code scanner is mounted above the conveying mechanism; according to the utility model, the solar assembly bar code isnamed as the junction box picture information; an EXCEL table is generated through bar codes and compared with bar codes of each shift every day, bad welding products are stored through files, the specific time of the bad weld
