The working process of the appearance detection of the electrolytic capacitor 001 of the embodiment is as follows:
the electrolytic capacitor 001 is fed into the capacitor distributing chute 1030.
The double-stroke cylinder is retracted so that the V-shaped jaws of the mobile gripping mechanism 2000 are aligned with the jaws of the lower gripper mechanism 3000 in an initial state (see fig. 1).
One end of the double-stroke cylinder is pushed out, and the movable grabbing mechanism 2000 moves one step left along the guide rail (see figure 12).
