Final assembly of autoinjectors / on-body injectors (insert syringe, seat springs, snap closures)

Drug-delivery device assembly combines a filled glass syringe or cartridge with plastic housings, drive springs, plunger rods/backstops, needle shields, and caps into a functioning autoinjector or on-body injector. The robot performs a multi-step sequence: insert the fragile primary container into the device chassis, press-fit retention components, seat springs, and engage snap-fit closures and caps, all to sub-millimeter alignment. Components are small, mixed rigid-plastic and glass, of low tolerance to misalignment, and the finished device must reliably deliver dose. It is hard because each engagement must be FELT to confirm — over-force cracks the glass syringe or deforms plastic, under-force leaves an unseated component that fails function. AbbVie's pending acquisition of West's Tempe on-body-injector lines and its existing autoinjector packaging at Lake County make this an explicit, expanding capability. We identified this through our own research; we have not confirmed the specifics with the customer directly. This page is our researched read — a starting point for that conversation.
