Robot arm

Abstract

The invention discloses a robot arm. The robot arm structurally comprises a cable, a connecting arm, clamping blocks, cable inlets, a rotating disc, a base, a groove, rotating shafts, a manipulator and a connecting shaft; the cable runs through the cable inlets and is arranged in the connecting arm, a signal end of the cable is electrically connected with an electrical system in the connecting arm, the clamping block is fixedly welded on the smooth face of the groove, the groove and the rotating disc are integrated, the rotating disc is mechanically connected to the top of the base, the threerotating shafts are arranged at the left and right sides of the connecting arm respectively to form a transmission system, the clamping blocks are in bolt connection to the upper and lower sides of the rotating shafts, the connecting shaft is mechanically connected to the bottom of the rotating shaft, and the manipulator is fixedly arranged on the bottom of the connecting shaft; the connecting shaft is internally provided with a retractable clamping device so as to control the size of the manipulator when the manipulator extracts goods, so that the stability is good when the manipulator extracts the goods, and the goods cannot fall off.

Description

technical field [0001] The invention relates to a robot arm, which belongs to the field of robot arms. Background technique [0002] The robotic arm is the most widely used automatic mechanical device in the field of robotics. It can be seen in the fields of industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. There are differences, but they all have a common feature, that is, they can accept instructions and accurately locate a certain point in three-dimensional or two-dimensional space for operation. Because the arm of a robot cannot stretch when extracting items, the robot arm Narrow application range makes it inconvenient and impractical to use. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a robot arm to improve the disadvantages that the robot arm cannot be stretched and retracted when picking up objects, which narrows the application r...
