Reaction and articulated arms by Fiam can be fitted with a position monitoring device and, combined with the TPM monitoring unit, help make tightening systems very suitable for “Poka-Yoke” processes, while increasing the efficiency and speed of the production cycle.
In fact, they not only make the work station more ergonomic for the hand-arm system, but the man-machine collaboration also increases performance: the system supports operators and guides them through assembly operations and sequences, reducing mental fatigue due to the continuous attention required to control such operations.
The system is entirely designed and built by Fiam and consists of:
•BCA…TPM2 articulated cartesian arm with a position monitoring device that measure the linear and angular movement
•TPM monitoring unit
•connection cable
The guided positioning system operates as follows:
•It works through “self-learning”: it locates the screwdriver position at the various tightening points and stores them together with the sequence of actions and the number of screws (up to 35 positions/program and up to 8 programs).
•The TPM unit display offers a graphical system to guide operators progressively as they approach the tightening point.
•The screwdriver is enabled when it is at the first stored position (the TPM display shows POS.OK and the POS-OK LED on the telescopic arm lights).
•Each time a screw is tightened, the REMAIN display shows how many screws are left, indicating that it is ready to pass on to the next screw.
•The END signal comes on when the stored cycle is complete, and gives the OK to proceed with a new work cycle.
