The application of Lingchen IO in laser marking of lithium battery tabs

In the critical process of tab marking in lithium-ion battery production, Lingchen Technology's miniIO module (model LCTE-MINI-E1O16), with its powerful functions and stability, has become a reliable choice for achieving efficient and precise marking.

Analysis of Core Functional Modules

This module integrates two major functional areas, specifically designed for complex industrial scenarios.

Latching Function Area: Core functions: Encoder latching, high-speed input counting. Advanced features: Offset-triggered latching, product interval protection, latching offset triggering, and latching filtering. Key performance: Latching FIFO size is 255 points, latching level specifications are 24V NPN or PNP.

Triggering Function Area: Core applications: Material feeding triggering, offset triggering. Safeguards: Output interval protection, encoder speed compensation. Key performance: Triggering FIFO size is 128 points, output level specifications are 24V NPN.

Excellent triggering capabilities and special features

Intelligent point management: After setting the points, the module automatically sorts them internally, eliminating the need for external sorting and subsequent data input, thus simplifying the process.

Anti-false marking protection: Triggers an interval protection mechanism to effectively prevent false markings caused by multiple program judgments.

Efficient roll change operation: Supports direct roll replacement when a roll of material is nearly finished, without the need for material clearing, reducing downtime.

Marking and feedback locking function:  Utilizing the output signal of the marking machine, the encoder position value is instantly captured through high-speed latching, used to verify the accuracy of the marking position.

Actual marking output count: The number of marking machine output signals is counted using a high-speed counting function to accurately calculate the actual number of markings.

Encoder speed compensation: Dynamically compensates for marking position deviations caused by marking machine output delays at different speeds.

Encoder unidirectional counting: The counting method is synchronized with the CCD, ensuring that the encoder count of the module is completely consistent with that of the CCD.

Standard DIO Control (Debugging Mode): During debugging, you can switch to GPIO mode for direct level output, facilitating electrical debugging.

Internal Register Monitoring: Provides monitoring of various register states, including internal trigger count, actual trigger position, and trigger FIFO count, facilitating troubleshooting and system maintenance.

Summary

Lingchen Technology's LCTE-MINI-E1O16 miniIO module, with its 16 trigger channels, 12 latching channels, and encoder input frequency of up to 20MHz, along with its integrated latching and triggering functions and rich advanced features (such as automatic sequencing, multiple protection, speed compensation, feedback verification, and counting statistics), provides an efficient, precise, stable, and easy-to-maintain industrial IO solution for lithium battery tab marking applications, significantly improving production efficiency and product quality control.
