ATK needs an automated visual inspection system for their Speer brand
Gold Dot ammunition. Law enforcement officers use this product line
extensively, and due to the widespread use of automatic weapons it
is crucial that every cartridge
functions properly. The inspection of the product is currently done
through a human visual inspection. Existing automated inspection systems
for ammunition use cameras and sometimes lasers to inspect the cartridges.
Team Shot in the Dark will design an automated inspection system
and will have it completed, tested, and functioning by May of 2005.
Through this project Shot in the Dark team members are afforded the
opportunity to work closely with an industry professional with expertise
in visual inspection systems, allowing us to gain considerable knowledge
in high-speed product transfer and integrate computer, electrical,
and mechanical engineering technology into a coherent, functional
Overview of the final design
The solution created by Shot in the Dark consists of an indexing
wheel on top of the table to present the cartridges o the camera.
DVT camera will then inspect the cartridges for any defects and give
a pass or fail signal. The cartridges will continue and drop through
the surface of the table and a rejection mechanism will divert the
cartridges that fail. For further details on the completed design
please refer to the Final Design
