[0003] The production process of truck armrests includes tube bending, forming, punching, etc. In the bending process, the metal aluminum tube is bent. During the bending process, the aluminum tube needs to be bent into a corresponding angle, and then the corresponding plastic shell or grid-patterned adhesive is fixed on the position of the handle area of ​​the aluminum tube body for anti-slip treatment. Finally, the installation hole is drilled on the aluminum tube according to actual needs.

[0004] When bending aluminum tubes in truck handrail production, operators usually put the aluminum tubes on a bending machine, which then bends them into the shape of handrails. To improve the operator's safety, a robot is usually installed in front of the bending machine, and the operator places the aluminum tubes in a position where the robot can grab them. The robot then sends the aluminum tubes to the bending machine.
