Robotic Assembly Systems
Perfect Solutions® Technology
Dixon provides Robotic integration for Automated Assembly and Flexible Material Handing Processes. Over the
years, we have helped customers with tooling for Cartesian, Scara, and 6-axis Robots for their specific
production requirements. As a Robotic integrator, these robots are being equipped with vision systems to
recognize piece parts, insertion points, and verification of the production process at the work cell. Each
robot selected for a project requires our end-of-arm tooling and controls to meet the customer's production
criteria. Tooling these Robots provided threaded fastener insertion, piece part placement, pick-up and transfer
of sub-assemblies, machine tending and other related operations for a production process.
Robotic Assembly Cell
This assembly system uses a Cartesian Robot to transport a Dixon Auto-Fed servo controlled Driver and Vision
System to drive helical wire inserts into transmission housings. Due to casting variations, the Vision System
pre-locates all of the driving points on the casting for the Robot. The Dixon Auto-Fed Driver drives 12
helical wire inserts to a precise depth setting at each insertion point. A vibratory feed system orients the
inserts before they are escaped one by one and blown into the placement jaws of the Driver. The Vision System
is also utilized to inspect the final condition of the driven inserts.
Material Handling and Assembly System
A Material Handling and Assembly System using two 6-axis Robots. Both Robots grip and removes tube
sub-assemblies from a rotary dial. One Robot for a left hand tube, and the second Robot for the right hand
tube. Each Robot sequentially relocates each tube placing it on a fixture for subsequent piece part assembly
operations on each end. The Robots then place the completed sub-assemblies onto adjacent indexing conveyors.
Robotic Assembly System
Two Scara Robots are each programmed to pick up 8 Clips onto the end-of-arm tooling selected from three
vibratory feed clip presenter systems, and place them one at a time onto moldings located on a pallet
transfer system. Final installation of the Robot assembly system and programming was accomplished on the
customer's floor.
Pal Nut Auto-Fed Part Placer
A 6-axis Robot places Pal Nuts into instrument panels using a Dixon Auto-Fed Part Placer (Model AP-171) with
a Trav-A-Track attachment to convey the Pal Nuts. A Vibratory Feed System orients and feeds the Pal Nuts to
be loaded by the Part Placer Head and Robot. The Part Placer with the track attachment enables the Robot to
carry multiple Pal Nuts to the instrument panel for placement at the rate of (1) per second. Good part
sensing, is standard on every Dixon Part Placer, eliminated the need for in-position sensors in the
fixturing. This saved the customer on overall system costs.
