The swing cylinder directly drives the first swing rod to swing in a reciprocating mode, and the first roller moves in the cam groove of the first disc-shaped cam under the action of the first swing rod. The first suction nozzle support is guided by a first linear ball guide rail pair and a second linear ball guide rail pair which are vertically and crosswise arranged, and is driven by a first roller to realize the track motion of a cam groove, so that the first suction nozzle adsorbs a workpiece to transfer the workpiece from a blanking male die to the next procedure.
The first motor drives the braid reel to rotate, and the work piece braid is conveyed to the ratchet wheel through the buffer of the driven reel. The first ratchet support is fixedly connected with a first sliding block of the third linear ball kinematic pair, and the second ratchet support is fixedly connected with the feeding guide rail. The first ratchet support reciprocates under the action of the cylinder. Under the action of the second spring and the second air cylinder, the movable ratchet wheel reciprocates, and when in feeding, the sharp angle of the movable ratchet wheel is clamped in the hole of the material braid to drive the material braid to intermittently feed, and meanwhile, the braid drives the first static ratchet wheel to rotate, and the sharp angle of the movable ratchet wheel is lifted. When the cylinder rod is retracted, the sharp angle of the movable ratchet wheel is lifted, and the first static ratchet wheel is clamped into the braid hole, so that the material is prevented from being retracted.
