High Speed Automated Manufacturing System for Automotive Compact Relay

The conventional relay manufacturing line required several workers for manual assembly and adjustment operations. This problem was compounded by the fact that high precision quality of the product could not be easily achieved.

To solve these problems, Nippondenso has made a breakthrough in developing new technologies which were incorporated in an automated relay manufacturing line, enabling an individual process cycle time of 0.9 seconds throughout all manufacturing processes. This includes component parts fabrication, assembly, inspection, adjustment and packaging, and does not require the direct intervention of any operators. Various models of relays can be run at the same time in this line because the set up time for different models is almost zero. This greatly improves production control.
