The Problem
A new production line was to be introduced to manufacture several variants of dashboard by one weld machine. The weld machine contains 2 changeable nests to be used at the end of the line. The machine is loaded with 2 complete “GOOD” dashboards, with the parts being completed at the previous stages of production, and also any of the required extra ‘child’ components already fitted ready for the weld. The correct nest must also be loaded to ensure the weld machine welds correctly for the variation of dashboard loaded. Automated printing of part and Odette labels is also required to ensure the parts are not mislabelled on completion.
The Solution
Maxim supplied an End of Line (EOL) control system, utilising:
-
Industrial Fixed Position Barcode Readers
-
Industrial Thermal Printers
-
Inductive & proximity sensors
-
A custom control panel with HMI, RS232 communications and an IO connection box.
Utilising sensors to detect the nest and any child components, the Maxim Process Control Software confirms that the parts, nests and previous processes are all GOOD. Then, it sends a signal to the weld machine PLC to trigger the weld. Once the weld is complete, the Weld Machine PLC will send a signal to the Maxim PCS to print 2 final part labels. The Process Control Software also records an internal count of completed parts. Once the completed count reaches a pre-set value, a stillage Odette label is automatically printed
The Maxim Process Control System is a complete End of Line production control system.
