The utility model relates to a six-freedom-degree robot for feeding and discharging transformers on an automatic detecting assembly line. The robot comprises a base (1), a stand column (2), a fixed plate (3), a rotary disc (4), a movable supporting arm (5) and a transformer clamping claw (6). The bottom of the stand column (2) is fixed to the base (1), and the top of the stand column (2) is provided with the fixed plate (3). The rotary disc (4) is installed on the fixed plate (3). One end of the movable supporting arm (5) is arranged on the rotary disc (4), and the other end of the movable supporting arm (5) is connected with the transformer clamping claw (6). The rotary disc (4) and the movable supporting arm (5) are connected with a servo motor through a control circuit. The servo motor drives the movable supporting arm (5) to rise and fall and meanwhile drives the rotary disc (4) to rotate in the horizontal plane, so that six-freedom-degree movement is achieved. Compared with the prior art, the six-freedom-degree robot has the advantages of being simple in structure, light in weight, flexible, reliable and the like.
