Cylindrical Battery Beading with In-Line Position Measurement

The patent replaces mechanical position measurement methods with optical sensors (laser sensors) and electromagnetic sensors (eddy current sensors) to measure the positions of the beading knife, backup roller, upper CFB, and lower CFB. This substitution of mechanical systems with optical and electromagnetic sensing systems enables precise position detection without complex mechanical linkages, thereby improving manufacturing precision while controlling device complexity.

The patent introduces position measurement units as intermediary devices that mediate between the mechanical components (beading knife, backup roller, CFBs) and the control system. These measurement units provide accurate position data to the control system, enabling precise control of the beading operation without requiring direct mechanical coupling between all components, thus improving precision while managing system complexity.

The patent implements feedback control by using position measurement units to continuously monitor the positions of the beading knife, backup roller, upper CFB, and lower CFB, and feeding this information back to the control system. The control system uses this feedback to detect abnormal positions and identify defective units, thereby improving reliability through real-time monitoring and early detection of problems without requiring overly complex intervention mechanisms.

The patent enables the beading apparatus to self-diagnose and identify defective units through the position measurement units and control system. The system automatically detects abnormal positions of components, identifies which units are defective, and can signal for replacement or adjustment, reducing the need for manual inspection and intervention. This self-service capability improves reliability while keeping the added complexity manageable through automation rather than human labor.

The patent implements continuous position measurement during the beading operation using laser sensors and eddy current sensors that continuously monitor the positions of the beading knife, backup roller, upper CFB, and lower CFB throughout the operational cycle. This continuous measurement approach eliminates the need for separate measurement steps, allowing precision control to occur simultaneously with the beading process itself, thereby improving manufacturing precision without adding significant time loss.

The patent performs position measurements and defect identification in advance during the beading operation itself, rather than requiring post-processing inspection. The control system continuously monitors component positions and identifies defective units real-time, allowing problems to be detected before they result in defective products. This preliminary detection approach improves precision while minimizing time loss by eliminating or reducing subsequent inspection steps.
