Problems solved by technology

[0003] However, although the current six-axis robot has sufficient degrees of freedom, its rotation angle is also limited. If a larger rotation angle is to be obtained, the rotating arm must be appropriately lengthened, which will inevitably increase the power of the robot motor. It is also more bloated and bulky, which not only does not meet the requirements of energy saving and environmental protection, but also limits the application of six-axis robots in small places

Embodiment Construction

[0022] The present invention will be further described below in conjunction with drawings and embodiments.

[0023] In the embodiment, as attached figure 1 , attached Image 6 As shown, a six-axis robot includes a base 1, and a shoulder 2, a large arm 3, an elbow 4, a forearm 5, a wrist 6 and a hand 7 installed on the base 1 in sequence, and the elbow The upper arm 4 is a double-joint structure, and the upper arm 3 and the lower arm 5 are respectively hinged at the two ends of the elbow 4 . The double-joint elbow 4 of this embodiment increases the rotation angle of the six-axis robot on the same plane without increasing the rotation axis and ensuring sufficient degrees of freedom of the robot, and does not increase the overall size of the robot, and is especially suitable for small working environment, expanding the scope of use of six-axis robots. The range of motion of its hand 7 in the plane is as attached Image 6 As shown by the double dotted line in , it is much larg...

Abstract

The invention discloses a six-axis robot, which is used for reducing the overall size of the six-axis robot and enabling the robot to rotate arms flexibly. The six-axis robot is characterized in that an elbow is of a double-joint structure, and a large arm and a small arm are respectively hinged with both ends of the elbow. According to the six-axis robot, on the premise that a rotating shaft is not additionally arranged on the double-joint elbow and the sufficient degree of freedom of the robot is guaranteed, the rotating angle of the six-axis robot on the same plane becomes large, and the overall size of the robot is not increased, so that the six-axis robot is especially suitable for a narrow working environment, and the application range of the six-axis robot is enlarged.

Description

technical field [0001] The invention relates to the field of automation, in particular to a six-axis robot. Background technique [0002] The six-axis robot can move freely in three-dimensional space, and can accurately and quickly perform a large number of repetitive tasks such as handling, welding, and spraying. In traditional factories, handling, welding and other work are basically done manually, which has problems such as high labor intensity, time-consuming, boring, harsh working environment, poor process consistency, and difficult quality control. The cost of the enterprise very high. Therefore, in these fields, it has become a trend for six-axis robots to replace manual operations. [0003] However, although the current six-axis robot has sufficient degrees of freedom, its rotation angle is also limited. If a larger rotation angle is to be obtained, the rotating arm must be appropriately lengthened, which will inevitably increase the power of the robot motor. It i...
