Getting your Test Systems Robotics Ready

Posted by:

  • Understanding the test-related functions that can be better managed by later generation test instruments is relevant to any design of test and assembly processes.
  • The goal, of course, of incorporating robotics into any test-centric assembly is to achieve a faster test cycle time and increased assembly line throughput. As an example of what can be achieved, rear housings are leak tested to a 3.0 sccm accept limit at 24 kPa (3.5 psig) to 28 kPa (4.0 psig) requiring only 25 seconds from start to cycle completion.
  • Here the robot loads and unloads all parts being tested and all test inputs and outputs are communicated with the robot interface. The four different part configurations, i.e. different casting models, are identified by sensors that then determine the clamping type, sealing methods and leak test specifications.
  • InterTech’s patented PowerClamp® technology individually clamps each bolt point to simulate mounting conditions.

  • This white paper, “Mass Flow Leak Testing Technology Update”, is geared for engineering teams that are seeking proven methods to cut production costs without compromising product quality.  After reviewing the pros and cons of prior leak testing methodologies, we will drill into some detail re: the benefits of latest generation mass flow sensor systems that can be tuned to the specific pressure, temperature, part geometry and other application specifications.
  • Such systems can provide best gauge R&R leak testing in ranges as low as 0.01 sccm even for with parts with high internal volume high volume, and in the widest possible range of production line pressure or vacuum test scenarios.

Key areas covered in White Paper include:

    • Historic Leak Testing Methods
    • Accuracy Considerations
    • Test Cycle Times
    • Summary – Updated Mass Flow Sensors and Application Matching
