THREE-AXIS FLAT MANIPULATOR OF PARALLEL STRUCTURE Russian patent published in 2023 - IPC B25J1/00 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used to automate various operations in microelectronics and precision robotics. A three-axis flat manipulator of parallel structure includes a stand and a platform, between which three kinematic chains are installed, which include connecting rods. Each kinematic chain of the manipulator is equipped with a piezo actuator located in the housing, which is coupled on one side with a stand, and on the other side with an end cover and an elastic element through bolted connections. Each kinematic chain of the manipulator is equipped with a pair of elastic hinges, one of which is rigidly coupled between the end cap and the connecting rod, and the second is rigidly coupled between the connecting rod and the platform.

EFFECT: increases the rigidity of the structure and the accuracy of movement of the manipulator links.
