Abstract
A method of assessing the impact of ultrasonic welding on a part during a pre-production process, the method including providing a device that includes a housing having an optically transparent window and a part supported therein, applying an ultrasonic welding process to the housing according to a set of input variables, each input variable being applied at a first initial value, and measuring the vibration of the part during the ultrasonic welding process through the window, using a non-contact measuring process.
Claims24
A method of assessing an impact of ultrasonic welding on a part during a pre-production process, the method comprising:
- providing a device comprising a housing having a window and a part supported therein,
- applying an ultrasonic welding process to the housing according to a set of input variables, each input variable being applied at a first test value, and
- measuring a vibration of the part during the ultrasonic welding process through the window using a non-contact measuring process.
(canceled)
An apparatus for assessing an impact of ultrasonic welding on a device during a pre-production process, the apparatus comprising:
- an ultrasonic welding unit for applying an ultrasonic welding process to the device according to a set of input variables, each input variable being applied at a first test value, the device comprising a housing having a window and a part supported therein,
- a measuring unit for measuring a vibration of the part in a non-contact manner through the window of the housing, and
- a jig for supporting the device during the ultrasonic welding process,
- wherein the jig comprises a window through which the measuring unit can measure the vibration of the part during the ultrasonic welding process.
