| 30/06/2008 - Deutsch embraces change - Aylesbury Automation delivers a flexible solution |
A flexible robotic production cell solution has been delivered to Deutsch UK by robotics and automation specialist Aylesbury Automation. The robot-based machine has been introduced as a result of increasing product demand. It assembles a range of similar, two pin electrical plugs and sockets and produces one complete part every six seconds.
Matt Davidson, Production Engineering Manager at Deutsch UK says, “The new machine is excellent. We’ve had it running in production ever since commission. It is extremely reliable and the amount of operator adjustment necessary has been far less than we expected.”
Deutsch UK, a specialist manufacturer of interconnection equipment for harsh environments, required a flexible solution to match its process requirements at its manufacturing plant at St Leonards on Sea. By replacing a conventional rotary table with a robot, when product changes demand, Deutsch is able to reprogramme the machine instead of investing in new tooling. Robots in manufacturing require shorter lead times than conventional solutions with less mechanical parts requiring change when lines and processes are altered.
Plug caps and bodies are ultrasonically welded in a single assembly fixture by the Aylesbury Automation production cell. Two vibratory bowl feeders and linear drivers feed the parts into the machine. The bowls and linear tracks have been tooled to orientate the parts into the correct position to be picked up by a DENSO HS 45352G robot supplied by AA Robotics, the robotics division of Aylesbury Automation. Flexible design of the machine means that different similar components - where there is a change in shape of plug and socket body - can be accommodated very easily, by interchangeable bowl tops and linear feeder tracks.
The robot loads the parts under a Branson ultrasonic welder, after which a stamp is applied to some of the caps. A quality assurance, tensile (pull) test is made on selected products and the frequency of this testing is controlled by the customer, from the robot’s HMI panel.
There is no PLC in the production cell. All the machines functions are coordinated by the multi tasking robot controller using Devicenet I/O and this solution brings considerable cost savings. Six background tasks operate to control 128 I/O points and all status and error messages are shown on the robot HMI.
Deutsch has been using a robot for some time in the manufacture of products but, encouraged by the low capital cost of the Aylesbury Automation solution, the company is now exploring other processes which might benefit from robotic solutions.
“I’ve been most impressed with the the machine supplied to us,” says Matt Davison. “It has been running consistently in production since it was commissioned with products being manufactured and packaged directly into their shipping cartons. I hope this will be indicative of future equipment supplied by Aylesbury Automation as this has been a most successful project.”
