The invention relates to a capacitor pushing device which comprises a trough plate and a pushing and moving mechanism, wherein a trough is formed in the trough plate, the pushing and moving mechanism is arranged on the side of the trough plate, a plurality of pushing plates which are arranged in sequence along the trough are arranged on the pushing and moving mechanism, all of the pushing plates are connected with a horizontal moving air cylinder, the pushing plates can be driven to be close to and far from the trough by the horizontal moving air cylinder, the pushing and moving mechanism can reciprocate along the extension direction of the trough, two image devices are respectively arranged along the extension direction of the trough, and the two image devices are respectively arranged on two surfaces of the trough plate. By adopting the structure that the trough is formed in the trough plate, a capacitor can move to the shooting position of a CCD (Charge Coupled Device) camera along a specified path, and only a specified quantity of a plurality of capacitors are pushed by the pushing plates in batches; the trough is provided with steps, so that the capacitor can vertically enter the trough, then a guide pin vertically faces downward, the capacitor which is placed in the trough in the posture is stable and firm and cannot fall down in an inclined way, and the capacitor is easy to push.
