The visual detection mechanism 4 also comprises a platform lifting mechanism 4b and a second proximity sensor 4 c; the platform lifting mechanism 4b comprises a ball screw 4b1, a screw base 4b2, a through shaft type screw motor 4b3 and a screw nut 4b 4; the two screw bases 4b2 are fixedly arranged at two sides of the limiting conveying table 3, the ball screw 4b1 is vertically and fixedly arranged on the screw base 4b2, the ball screw 4b1 penetrates through two ends of the movable platform 4a, the through shaft type screw motor 4b3 is fixedly arranged on the upper plane of the movable platform 4a, the through shaft type screw motor 4b3 is arranged on one ball screw 4b1, the other ball screw 4b1 is sleeved with the screw nut 4b4, the fixing part of the screw nut 4b4 is arranged on the upper plane of the movable platform 4a, and the second proximity sensor 4c and the through shaft type screw motor 4b3 are electrically connected with the controller;

because the camera 4d3 of the equipment is positioned below the two sides of the movable platform 4a, if the camera is suspended at the same position all the time, the advance of the C-shaped card can be blocked, therefore, the equipment is provided with a platform lifting mechanism 4b on the movable platform 4a, the through shaft type screw motor 4b3 on the movable platform 4a drives the movable platform 4a to lift on the ball screw 4b1, and the screw nut 4b4 ensures the smoothness of the lifting; the C-shaped clamp is sensed by the second proximity sensor 4C before moving to the lower part of the movable platform 4a, so that the second proximity sensor 4C sends a signal to the controller, the controller sends working signals to the driving part of the limiting conveying table 3, the through shaft type lead screw motor 4b3 and the camera 4d3 respectively after delay, the limiting conveying table 3 stops conveying, the through shaft type lead screw motor 4b3 drives the movable platform 4a to descend, and the camera 4d3 photographs the C-shaped clamp.

The working principle of the invention;

when the equipment works, the C-shaped card slides into the feeding conduit 1b from the discharging hopper 1a, the inner channels of the feeding conduit 1b and the discharging conduit 1C are designed according to the size characteristics of the C-shaped card, so as to ensure that the C-shaped clamp keeps a vertical state when sliding in the feeding guide pipe 1b and the discharging guide pipe 1C, when the C-shaped card enters the directional sorting machine 2, firstly enters the feeding port 2a1 of the fixed turntable 2a, and then slid into the sorting slot 2b1 of the rotary disk 2b, if the C-type card is in a notch-up state with respect to the sorting slot 2b1, the C-type card is caught by the sorting slot 2b1 after the rotation, the C-shaped card can not slide down from the sorting channel 2C1 and continuously rotate, the C-shaped card is not clamped by the sorting groove 2b1 any more and can slide out from the discharge guide pipe 1C to the working surface of the limiting conveying table 3, and the C-shaped card is in a state that the notch is upward relative to the working surface of the limiting conveying table 3; when the C-shaped card slides into the sorting groove 2b1 from the feeding port 2a1, if the C-shaped card is in a downward notch state relative to the sorting groove 2b1, after rotation, the C-shaped card will directly slide into the discharging conduit 1C from the sorting channel 2C1 and finally slide onto the working surface of the spacing conveying table 3, and at this time, the C-shaped card is in an upward notch state relative to the working surface of the spacing conveying table 3; the servo motor 2f is used for driving the rotating disc 2b to rotate between the fixed rotating disc 2a and the sorting cover 2C and driving the C-shaped card to turn over; the C-shaped card is driven by the limiting conveying table 3 to extend backwards, the bevel edge of the guide plate 3a advances, the tail section of the guide plate 3a is a baffle plate with the extending direction consistent with the working direction of the limiting conveying table 3, the C-shaped card is moved between the guide plate 3a and the limiting cylinder 3b and is sensed by the first proximity sensor 3C, the first proximity sensor 3C sends a signal to the controller, the controller sends a working signal to the limiting cylinder 3b after delay, and the limiting cylinder 3b pushes the C-shaped card which is just moved to the front of the working part of the limiting cylinder 3b onto the guide plate 3a, so that the orientation of the C-shaped card is consistent with the working direction of the limiting conveying table 3; the C-shaped clamp is sensed by the second proximity sensor 4C before moving to the lower part of the movable platform 4a, so that the second proximity sensor 4C sends a signal to the controller, the controller sends working signals to the driving part of the limiting conveying table 3, the through shaft type lead screw motor 4b3 and the camera 4d3 respectively after delay, the limiting conveying table 3 stops conveying, the through shaft type lead screw motor 4b3 drives the movable platform 4a to descend, and the camera 4d3 photographs the C-shaped clamp.
