Portable Sub-Assembly Station
Customer automation need
The Customer needed to improve assembly quality because of high production demands. They required an automation system to assemble a three component sub-assembly. Their current process was using hand fixtures. Three parts were assembled, a 1000 cps silicone oil was applied to one of the pieces (approx. 5 microliters), and offloaded into bulk.
McClellan was asked to design and build a portable semi-automated machine to produce the sub-assembly at a rate of 20 completed assemblies per minute, with the following design restrictions:
- Must fit through a 36" wide doorway
- Must be capable of being moved repeatedly (machine to be mounted on casters)
- Bowl Hoppers must hold (1) hour of run time
- All electrical controls mounted under the machine frame
- Class 100,000 Clean room compatibility
- Limited budget
- 5 months Customer timeline
