Application Case of Atonm MDSC-2100L Single/Double-Sheet Detector in Lithium Battery Stacking Machines

I. Project Background

A lithium battery manufacturing enterprise conducts lamination operations using copper-aluminum sheets with a thickness of 0.01mm and dimensions of 75×60mm during production, with the production line speed requirement reaching 40 sheets per minute.

Due to the narrow internal space of the laminating machine, traditional double-sheet detection equipment is difficult to install. Moreover, the copper-aluminum sheets are extremely thin, making conventional detection methods unable to meet the accuracy requirements. This results in frequent occurrences of undetected double-sheet issues, which seriously affect the production quality and efficiency of lithium batteries.

II. Challenges

Detection Accuracy Challenge

The copper-aluminum sheets, with an ultra-thin thickness of 0.01mm, show almost no noticeable difference when double-layered. Traditional detection equipment struggles to identify double sheets accurately. Undetected double sheets entering subsequent processes will affect battery performance and increase the defective rate.

Space Constraint Dilemma

The internal structure of the laminating machine is compact, leaving limited installation space for detection equipment. Many standard-sized detectors cannot be installed; even forced installation may interfere with the normal operation of other components of the laminating machine.

High-speed Production Line Pressure

With the production line running at a speed of 40 sheets per minute, the detection equipment is required to respond rapidly, completing detection and feeding back results in a short time. Otherwise, production downtime will be caused by detection delays.

III. Solution

The enterprise adopted the Atonm Double-Sheet Detector MDSC-2100L. This device is specially designed for thin materials in the lithium battery industry, equipped with customized high-sensitivity small-probe sensors, and is a contact-type double-sheet detector, making it ideal for installation in equipment with compact internal structures.

Accurate Detection

Tailored to the characteristics of copper-aluminum sheets, the MDSC-2100L can accurately identify double-sheet conditions with high detection precision, effectively eliminating the problem of undetected double sheets.

Easy Installation

Its compact design allows easy installation in the narrow space inside the laminating machine without requiring large-scale modifications to the equipment, thus saving installation costs and time.

Rapid Response

The response speed can reach up to 1200 sheets per minute, far exceeding the production line's requirement of 40 sheets per minute. This ensures timely detection and result feedback during high-speed production, maintaining production continuity.

IV. Application Effects

Quality Improvement

After implementing the MDSC-2100L Single/Double-Sheet Detector, the rate of undetected double sheets dropped dramatically. This led to a significant reduction in the defective rate of lithium batteries, effectively improving product quality and strengthening the enterprise's competitiveness in the market.

Efficiency Enhancement

The device’s ultra-fast response speed fully meets the demands of the high-speed production line, minimizing production downtime caused by detection delays and substantially increasing overall production efficiency.

Cost Reduction

The decline in defective rates and improved efficiency have allowed the enterprise to effectively control production costs, including reduced raw material waste and fewer equipment maintenance cycles, bringing substantial economic benefits.
