Utilizing a high vacuum chamber, the test system is used to test pre-charged parts for leaks which are too small to be detected via vacuum or pressure decay tests. It replaces the subjective bubble leak test while eliminating hours of required test time. Typical configuration consists of pressurized air supply for high vacuum chamber door operation along with a 460/3/60 power supply to minimize system current draw. Once the chamber door is closed, the roughing pump evacuates the chamber in preparation for the ultra-fine leak test. After part leak test is complete, the chamber is vented, the part may be removed and the system resets for the next test.

The system Base Unit is located above the assembly line and supplies the input / output (I/O) power and regulated air to the Console and Fill Tool. The Base Unit consists of an electrical enclosure and a mechanical plumbing panel. The electrical enclosure contains the fill system transformers, power supplies, fuses, circuit breakers, and a programmable logic controller (PLC). The mechanical plumbing panel contains an air filter, air dryer, air regulators, pressure switches, solenoids, booster pumps, two holding tanks, and a compressor.

The system festoon is attached to a rail over the vehicle assembly line (using trollies) and provides sufficient travel for the Fill Tool to fill a vehicle as it moves down the assembly line. Suspended from the festoon are the Fill Tool, an eight-way connector, and the operator pendant including Start / Stop pushbuttons.

In addition to the wind tunnel, the test system can also be configured to supply liquid utilities as required to dissipate any thermal needs. The test system also includes data collection which can be utilized to log inlet/outlet conditions along with temperature profiling as needed. Depending on the specific needs, the wind tunnel can be set up for either open or closed loop operation.

Typical configurations consist of a tunnel with a flow meter, proportional flow control valve and or a blower to provide the required mass flow. The flow is conditioned with dryers, chillers or heaters as required conditioning the mass flow before and after the test station. Chillers and heaters along with proportional valves are, also, used to provide liquid mass flow at the desired levels for secondary flow management. The test may be run from several minutes to several hours. Additional power utilities required are a compressed air supply and 460/3/60 electrical power.

Use of the PCU soldering machine only requires the operator to take the straight pre-cut capillary tubing and suction line from the supply rack place them into the carriage on the loading table clamp them into position and push the leading ends into the soldering section of the machine. The rest of the operation is completely automatic. The soldering assembly is fed from the machine and deposited onto a storage tray. It is not necessary for the operator to come near the soldering section of the machine at any time.”

The rotary index table is setup so that the early stations are utilized for component assembly and the latter stations utilize various testing technologies to verify the assembly’s integrity and may perform a final fluid fill. Each station is designed for independent operation and is able to be individually configured.

Typical configuration consist of a pressurized air supply for articulation and operation along with a 460/3/60 power supply to minimize system current draw. The component assembly stations are fed with bowl feeders and configured with a pick and place arm. The assembly is then fed into an integral mass spectrometer for ultra fine leak testing. The mass spectrometer utilizes a high vacuum chamber to facilitate the automated leak test. After part leak test is complete, the helium is removed from the part and the part is prepared for final fluid fill. The final stages are used to check the completed assembly with vision systems and run testing. Finally, the part may be removed from the index table manually or with an automated articulating assembly.
