Ultrasonic Welding Horn Fixing for Precise Battery Tab Angle Setting

The patent replaces the traditional mechanical indicator measurement system with an optical measurement system. A laser displacement sensor is used to measure the position of the horn tip, providing accurate digital readings of the horn angle without the mechanical errors inherent in traditional indicators. This substitution eliminates the discrepancy between measurement values and actual rotation amounts.

The patent introduces a laser displacement sensor as an intermediary measurement device between the horn and the measurement system. This intermediary provides precise, contactless measurement of the horn tip position, enabling accurate angle determination without directly coupling the measurement device to the horn, thus avoiding mechanical errors and deviations.

The patent employs a dynamic adjustment mechanism where the horn angle can be precisely adjusted during the clamping process. The system allows for real-time measurement and adjustment of the horn angle, enabling operators to achieve the desired angle before final tightening. This dynamic approach ensures both adjustability and stability, as the angle can be optimized before the clamping force is fully applied.

The patent implements preliminary angle adjustment and measurement before final clamping. The laser displacement sensor measures the horn angle during the adjustment phase, allowing operators to set the correct angle before applying full clamping force. This preliminary action prevents angle deviation that would occur if adjustment were attempted after clamping.

The patent replaces manual visual checking and copper hammer positioning with an optical measurement system. The laser displacement sensor provides precise, digital measurement of the horn position and angle, eliminating the need for visual estimation and manual hammering. This substitution dramatically improves both the precision and speed of the horizontal setting process.

The system enables self-adjusting capability through real-time optical feedback. The laser displacement sensor continuously monitors the horn position, allowing the system to automatically detect and correct positioning errors without manual intervention. This self-service approach eliminates the need for operators to use copper hammers and visual checking, improving both precision and efficiency.
