SCARA industrial robot

The utility model discloses an SCARA industrial robot, and relates to the field of SCARA industrial robot structures. The rotary inertia is small, the acceleration capacity is good, the transmission efficiency is high, the operation precision is high, and the operation stability is good. According to the technical scheme, the SCARA industrial robot comprises a base, a large arm assembly and a small arm assembly which are sequentially hinged. The large arm assembly comprises a large arm and a small arm driving mechanism arranged in the large arm, the small arm driving mechanism comprises a rotating power source fixedly installed in the large arm and a transmission mechanism connected to an output shaft of the rotating power source, and the transmission mechanism is further connected with the small arm of the small arm assembly; and the rotary power source is positioned above the base. Rotational inertia of the J1 joint and the J2 joint is reduced, then the rigidity of a robot body is improved, the dynamic acce
