Abstract: The disclosure provides a multiple superposition detection system and a multiple superposition detection method for capacitor appearance defects based on visual detection, relating to a capacitor detection field. The detection system includes a conveying mechanism, a visual detection mechanism, a loading mechanism, a sorting mechanism, a clamping mechanism and a clamping component; a driving mechanism is further arranged in the conveying mechanism. The capacitor is horizontally placed in the clamping mechanism of the conveying mechanism through the negative pressure pick-and-place mechanism, when the conveying mechanism drives the capacitor to sequentially penetrate through the three detection stations, the clamping mechanism is matched with the driving mechanism, and the front face and the side face of the capacitor are displayed to the visual detection mechanism. After detection, high-quality capacitors and defective capacitors are separately stored through the sorting mechanism.

Abstract: A scroll compressor and an air conditioning system are provided. The scroll compressor has a housing, a compression mechanism portion, a main frame, a motor, a crankshaft, a main balancing block and an exhaust pipe. In a radial direction of the housing, the exhaust pipe extends into the housing at a depth W, and an outer peripheral wall of the main balancing block is located at a distance L from an inner wall of the housing, where 0.47?W/L?0.93. In this way, a part of a high-pressure oil-gas mixture generated by the compression mechanism portion is discharged through cyclone separation of the main balancing block and mechanical separation of the housing; and the other part of the high-pressure oil-gas mixture flows into an axial channel to achieve oil and gas separation while cooling the motor, and is subsequently discharged.
