The invention discloses a horizontal multi-joint robot which comprises a base, a first arm body and a second arm body which are sequentially connected, and further comprises a first motor arranged at the joint of the first arm body and the base and a second motor connected with the second arm body through a transmission device. The projection of the first motor and the projection of the second motor on the vertical plane of the axis of the first motor are at least partially overlapped, the first arm body and the second arm body are directly driven through the first motor and the second motor respectively, a speed reducer can be omitted, and therefore the situation that precision, speed, cost and dragging torque of the horizontal multi-joint robot are affected due to limitation of the speed reducer is avoided; and the first motor and the second motor are at least partially overlapped, so that the distance between the axes of the two motors can be reduced, the output torque requirement of the first motor is reduced, the overall size and mass of the horizontal multi-joint robot can be reduced, and high acceleration and high speed of the horizontal multi-joint robot can be realized.
Description
technical field [0001] The invention relates to the technical field of robots, in particular to a horizontal multi-joint robot. Background technique [0002] The horizontal multi-joint robot, also known as SCARA (Selective Compliance Assembly Robot Arm), is a robot arm used in assembly operations. Generally, a horizontal multi-joint robot is provided with three rotatable joints. The first joint is located at the connection between the base and the first arm body, the second joint is located at the connection between the first arm body and the second arm body, and the third joint is located at the first joint. The end of the second arm body is far from the first arm body, the axes of the three joints are parallel to each other, the positioning and orientation can be carried out in the plane, and the action is simple, efficient and low in cost. [0003] The inventors of the present application have found in their long-term research and development that, [0004] At present, ...
