Customer's Need/Requirement: The customer needed a complete manufacturing line for a new precision cable assembly to unspool up to 9 wires and bind them together with a controlled twist to ensure even electrical properties. Once the bundle was created it had to be covered with film tape and a consistent overlap and respooled so that it could be moved to the next operation.
CAM's Solution: A custom comprehensive line was created by combining several proven components. The wire spools are mounted on shafts on a rotating frame. Each spool has a rotating frame and an individual brake to produce tension in the wire so that it is straight and taut while being formed into the bundle. The frame rotates the spools at the preset speed to produce the programmed twist.
Wires are gathered into a rotating die which ensure perfect alignment. Once combined, the bundle passes through an FT Taping Head to apply the film cover tape. The taped bundle is wrapped onto a spool. A precision layering device guides the wires onto the spool so that the bundle is evenly placed and does not become tangled. The drive system pulls with constant force to help the bundles on the spool tight.
This is an example of how CAM combines our proven technology for machine integration automation into a comprehensive line.
