AI Technical Summary
When the main arm of an existing industrial robot is connected to a cable, the movement of the robotic arm will cause the cable to rub against each other, resulting in excessive wear of the cable sheath. Over time, this can easily lead to cable breakage.
Moving parts, including springs and cable loops, are installed inside the cable inlet of the industrial robot arm. The springs reduce cable friction by providing cushioning, and ball bearings are installed on the inner wall of the cable loops to guide the cables and improve cable threading efficiency.
The design of springs and balls reduces the friction and pulling of the cable, avoids excessive wear on the cable sheath, and extends the service life of the cable.
