Ultrasonic welder with controlled seal compression |
摘要 |
<p>A two stage process of ultrasonic welding is disclosed wherein a first stage determines the amount of displacement required to produce a desired compressive force upon a seal or spring. This displacement is sent to a second stage where the desired displacement is achieved through ultrasonic bonding. In an alternative embodiment, the first stage determines the amount of displacement required to achieve non-compressive contact between the gasket (seal) and the component. This displacement is summed with an empirically determined displacement required to obtain a desired compressive force upon the gasket. The summed displacement is used as the desired displacement for the second stage.</p> |
