Medical Vial Assembly Machine
Most insulin packs come in a pre-measured syringe that the patient uses to inject themselves. This machine assembles the plunger, stopper, and two o-rings into a barrel, along with a septum and snap cap that seals off the inside of the syringe from the distal end. It then places a transfer guard onto the septum end and orients it radially. The machine operates around a precision link indexer that produces two complete and tested syringes at a time.
Each of the stations’ main actuation is driven off of a cam connected to the main indexer. This allows for complete accuracy in timing stations with the indexing of the nests that support the assemblies. The barrels are lubricated and installed over the plunger assembly and the finished assemblies are actuated back and forth to make sure they operate correctly.
