Guide rail slider assembly 8, fisheye ball bearing assembly 9, parallel arm 10, actuator fixture 11, actuator 12, limit switch 13, photoelectric switch 14, control system 15, first kinematic chain 5, second The second kinematic chain 6 and the third kinematic chain 7 connect the double delta parallel robots to work in series, and complete the same work under the action of the STC single-chip microcomputer controller, changing the single operation of the existing delta parallel robot or the low efficiency of the independent operation of two single delta parallel robots. Disadvantages such as high cost and small working space, the actuator drives the pneumatic suction cup to rotate through the installation of a motor and a coupling to realize the control of the rotation and alignment of the operating object, and has strong operational adaptability and wide adaptability.
