Involve, Test & Control Inc., a builder of leak test systems in Shelby Township, Mich., has designed and manufactured a special dual-fixture, three-position shuttle transfer machine to leak test large plastic covers for battery packs used by a maker of electric vehicles.
The company does not name the automaker.
The shuttle transfer machine measures 20 feet long and 7 feet wide. The two platens are indexed in and out of the leak test station. Acceptable parts are marked with a green ink spot.
The cycle time is 75 seconds.
The parts are automatically clamped, sealed, leak tested and transferred into the test station where an upper, rectangular-shaped chamber is lowered over the part, enclosing it. The chamber has viewing panels and LED lighting. The helium leak testing sequence then begins.
If rejected, the part remains pressurized and the chamber is vented. The operator can use a helium sniffer want to locate the area of leakage.
