In the embodiment, the five station cameras are adopted to take pictures of the pin, the pin surface, the top surface and the outer surface of the workpiece electrolytic capacitor 001 to be detected respectively, so that the workpiece electrolytic capacitor 001 to be detected is subjected to more comprehensive appearance detection.
In this embodiment, five station cameras are used for photographing and checking, and the application of the station cameras is a conventional technology in the prior art, and this embodiment is not described.
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 the attached figure 11). At the moment, the rotating mechanism 40000 rotates for a circle, and the station-one camera 5001 is matched with the rotating mechanism 40000 to shoot the periphery of the capacitor; meanwhile, the station four-camera 5004 shoots the top surface of the capacitor.
The piston at the other end of the double-stroke cylinder is pushed out, and the movable grabbing mechanism 2000 moves one more step left along the guide rail (see figure 12). At this time, the jaws of the movable gripper mechanism 2000 are clamped, and simultaneously the jaws of the lower gripper mechanism 3000 are loosened; an upper pneumatic grabbing mechanism 2100 in the movable grabbing mechanism 2000 at the a-clamping station clamps one electrolytic capacitor 001 from the capacitor distributing chute 1030. The upper pneumatic grabbing mechanism 2100 positioned at the B clamping station in the movable grabbing mechanism 2000 clamps the electrolytic capacitor 001 positioned at the a station in the lower clamping mechanism 300;
the piston at the other end of the double-stroke cylinder retracts to move the gripper mechanism 2000 one step to the right along the guide rail (see fig. 13). The second-station camera 5002 shoots the to-be-detected workpiece electrolytic capacitor 001 pin leg clamped by the upper pneumatic grabbing mechanism 2100 at the C clamping station; the station three-phase machine 5003 is used for shooting the pin surface (namely the end surface where the electrolytic capacitor 001 pin is located) of the electrolytic capacitor 001 of the workpiece to be detected, which is clamped by the upper pneumatic grabbing mechanism 2100 at the position of the D clamping station; the five-station camera 5005 obliquely photographs the pin surface of the electrolytic capacitor 001 of the workpiece to be detected (namely the end surface where the pins of the electrolytic capacitor 001 are located) clamped by the pneumatic grabbing mechanism 4230 in the rotating mechanism 4000. At this time, the electrolytic capacitor 001 held at the E holding station of the movable gripper 2000 determines whether or not the electrolytic capacitor 001 has an appearance defect; if the appearance flaw exists, the clamping opening of the air cylinder at the station is loosened, so that the electrolytic capacitor 001 with the flaw falls into a defective collecting box (not shown in the figure) below under the gravity; if the product is genuine, the cylinder is not operated.
One end of the double-stroke cylinder is retracted, and the gripping mechanism 2000 is moved to the right by one step along the guide rail, and then returns to the initial position (see fig. 1 and 14). At this time, all the jaws of the movable grasping mechanism 2000 are loosened, and simultaneously, the jaws of the lower grasping mechanism 3000 are clamped; and the qualified electrolytic capacitors 001 clamped on the clamping station E of the movable grabbing mechanism 2000 are placed in the finished capacitor discharge chute 1040. At this point, the two-stroke cylinder is retracted, in the initial state (see fig. 1).
The piston at one end of the double-stroke cylinder is pushed out, and the movable grabbing mechanism 2000 moves one step (see figure 11) … … leftwards along the guide rail, and the actions are repeated.
