[0002] The robotic arm is the most widely used automated mechanical device in the field of robotic technology. It can be seen in industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. Although their forms are different, they all have a common feature, which is the ability to receive instructions and accurately locate a point in three-dimensional (or two-dimensional) space to perform operations. At present, some robotic arms are usually fixed on a mounting frame during installation, and the mounting frame mainly includes a cylindrical connecting profile (hereinafter referred to as the cylinder) and a connecting piece. Corresponding mounting holes are provided on the cylinder and the connecting piece, and are fixed by bolts. There are many mounting holes on the cylinder to adapt to different fixing positions of the connecting piece, but because there is a certain spacing between the mounting holes, the installation position of the connecting piece has certain limitations. To this end, we provide a connecting profile for an industrial assembly line robot robotic arm to solve the above problems. Utility Model Content
