Manipulator grabbing equipment

The utility model discloses mechanical arm grabbing equipment which comprises a composite suction cup, the composite suction cup comprises a first suction cup and a second suction cup fixedly connected to the first suction cup, the first suction cup is fixedly communicated with a suction pipe, movable suction openings are symmetrically formed in the suction pipe, and the second suction cup is fixedly connected to the second suction cup. A plugging block is arranged at the first end of the movable suction opening, and the first suction cup extends out of the second suction cup by a preset distance. According to the mechanical arm grabbing device, the composite suction cup is utilized, when the mechanical arm grabbing device is used, the first suction cup makes contact with an adsorption face, then the first suction cup conducts suction so that a workpiece can be pulled close to the second suction cup during suction, and when the adsorption force of the first suction cup reaches a preset value, the second sucti
