Helium Leak Tester for Auto Battery Covers

摘要

Involve, Test & Control (ITC), Shelby Township, Mich., a designer and builder of leak-test systems, recently built a special dual-fixture, three-position shuttle transfer machine to teak test two different types of large plastic battery covers for electric cars. The machine is 20 ft long and 7 ft wide. Two dual-fixture platens are indexed in and out of the leak-test station in the center of the machine. While parts are being tested in one fixture, parts are manually unloaded from the other fixture and then reloaded with new test parts. The shuttle fixtures move back and forth with a servo-controlled bearing and rail-type linear transfer system. Cycle time is 75 sec.
