Description

Technical Field

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming, etc. Its most notable feature is that the thickness of the same part is consistent. The products processed by the sheet metal process are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used for assembly. Sheet metal parts are often used in air conditioners. The sheet metal parts of air conditioners often need to be inspected for defects on the surface of the sheet metal parts after production to avoid defective products from entering the market. When identifying conventional sheet metal defects, after the frame is installed and stabilized, a conveyor belt is installed on the inner wall of the frame. The conveyor belt is used to transport the sheet metal parts to the upper end of the frame, and the detector on the top of the frame is used to detect the surface of the sheet metal parts.

[0003] With respect to the above-mentioned related technologies, the inventors believe that when conventional sheet metal parts are inspected, since the detector is located at the upper end of the sheet metal parts, after inspecting one side of the sheet metal parts, the sheet metal parts need to be flipped over for inspection at the bottom, thereby reducing the inspection efficiency of the sheet metal parts and affecting the use effect of the sheet metal parts detector.
