An 8-up, four-component assembly, labeling, and packaging machine for auto injectors.
Rate / Platform
150 assemblies per minute. Precision link indexing in combination with continuous motion.
Challenge to Solution
The challenge was complex labeling with a tamper-evident tear-seal. The solution was precision servo control with electronic gearing.
Technologies
- Servo driven, precision link indexer
- High speed vision inspection
- Plasma surface treating for label application
How It Works
The assembly line builds each auto-injector through seven precision stations, combining vibratory feeding, servo-driven pick-and-place, and custom pucked conveyance between modules.
1. Cover Pick and Place
- Vibratory bowl feeders
- Pneumatic dicing mechanism
- Components placed in a custom fixture plate mounted to the precision indexer links
- Servo-driven, cam-guided pick-and-place platform
2. Driver Pick and Place
- Vibratory bowl feeders
- Pneumatic dicing mechanism
- Components placed in a custom fixture plate mounted to the precision indexer links
- Servo-driven, cam-guided pick-and-place platform
3. Plunger Pick and Place
- Vibratory bowl feeders
- Pneumatic dicing mechanism
- Two-stage pick and place
- Components pressed into the mating part
4. Driver/Plunger Pick and Place
- Two-piece plunger and driver subassembly placed into the cover
- Servo-driven, cam-guided pick-and-place platform
5. Puck Load Pick and Place
- Vibratory bowl feeders
- Subassemblies placed into pucks for conveyance
- Pucks indexed by a custom linear screw indexer
- Servo-driven, cam-guided pick-and-place platform
6. Housing Pick and Place
- Trays of components loaded into a downstacker
- Pucks indexed by a custom linear screw indexer
- Housings removed from trays with a gantry-style pick and place and pressed onto the cover subassemblies
7. Packout Pick and Place
- Empty packout trays loaded in from a downstacker
- Pucks indexed by a custom linear screw indexer
- Completed assemblies removed from pucks by a gantry-style pick and place
- Full packout trays pushed onto the outfeed conveyor
