Abstract
Apparatus comprising a conveyor adapted to move a plurality of test receptacles along a given path. Spaced along the path are means for adding a test fluid to the receptacles; first means for checking a desired parameter of the test fluid; means for inserting a cell; second means for checking the fluid for changes after a sufficient digestion period; means for comparing the two readings; and means for removing the cell. Additional means can also be provided for emptying the test fluid and rinsing the receptacles.
Claims4
An apparatus for leak testing electrochemical cells comprising:
- conveyor means adapted to move a plurality of test receptacles along a given path;
- a first work station disposed at a starting point of said path comprising means for dispensing a test fluid into said test receptacles;
- a second work station adjacent said first work station and downstream therefrom comprising first means for checking at least one particular parameter of said test fluid;
- a third work station adjacent said second work station and downstream therefrom comprising means for delivering an electrochemical cell into said test receptacle containing said test fluid;
- a fourth work station disposed downstream from said third work station a digestion distance comprising a second means for checking said at least one particular parameter of said test fluid;
- means for comparing said first and second checks to determine if said cell leaked;
- and means for removing said cell.
