AUTOMATED EVACUATION AND SEALING PROCESS

摘要

An automatic chamber evacuating method, system, and apparatus are disclosed, which include a nest, wherein a region or chamber, such as for example the reference chamber of an absolute pressure sensor, may be placed. A switch is used to initiate an automatic process whereby an air operated chuck seals to a tubular region protruding from the chamber via compressed air. An evacuating device connected to the tubular region by the chuck then applies a vacuum which evacuates the chamber. When the chamber has been sufficiently evacuated a message is sent to a programmable logic controller which then outputs a signal to an ultrasonic welding apparatus. The ultrasonic welder crimps and seals the tubular region thereby quickly and efficiently creating a permanent vacuum in the chamber.
