Diagnostic System and Method for Testing Integrity of Stack During Ultrasonic Welding |
| 摘要 |
A method for testing the integrity of a stack during ultrasonic welding, includes the steps of: (i) ultrasonically welding two or more work pieces with a stack, the stack including a convertor and a horn; (ii) measuring a frequency profile based on a vibration of the horn during the welding step; and (iii) comparing the measured frequency profile to a standard frequency profile to obtain an error rate, the error rate being indicative of a difference between the measured frequency profile and the standard frequency profile. A system employing the aforementioned method is also provided. |

1. A method for testing the integrity of a stack during ultrasonic welding, comprising the steps of:
ultrasonically welding two or more work pieces with a stack, the stack comprising a convertor and a horn; measuring a frequency profile based on a vibration of the horn during the welding step; comparing the measured frequency profile to a standard frequency profile to obtain an error rate, the error rate being indicative of a difference between the measured frequency profile and the standard frequency profile. |
