Abstract
A system and a method for determining whether an ultrasonic horn is aligned with an anvil of an ultrasonic welding system are provided. The first and second accelerometer sensors generate first and second signals indicative of first and second accelerations of first and second positions on a bracket coupled to the anvil when the ultrasonic horn is vibrating and contacting the anvil. The system further includes a microprocessor that receives the first and second signals. The microprocessor determines a difference between an amplitude of the first signal at a first time and an amplitude of the second signal at the first time. The microprocessor stores a first identifier value in a memory device indicating that the ultrasonic horn is aligned with the anvil if the difference between the amplitude of the first signal and the amplitude of the second signal is less than or equal to a threshold value.
