The core link of digital transformation - intelligent production line detection

In the production process of lithium batteries, electrode manufacturing is a key process that determines battery performance and safety. From coating, rolling to slitting, laminating/winding, every process cannot be separated from precise detection and control. Especially for dual pole detection - once two pole pieces overlap and enter the next process, it can cause equipment jamming and shutdown, and in severe cases, it can lead to internal short circuits in the battery cells, posing a risk of thermal runaway.

The traditional testing method for lithium battery production lines mainly relies on manual sampling and simple mechanical testing, which has three major pain points: firstly, the testing speed cannot keep up with the pace of the production line. High speed slitting machines can produce thousands of pole pieces per minute, which cannot be covered by manual testing; Secondly, the detection accuracy is greatly affected by human factors, and the missed detection rate fluctuates significantly; Thirdly, the detection data cannot be precipitated, making it difficult to support quality traceability and process optimization.

Under the background of digital transformation, production line inspection is shifting from "post inspection" to "online full inspection", and upgrading from "manual judgment" to "intelligent decision-making". Magnetic induction ultra-thin material detection equipment, represented by the Atorm MDSC-2100L dual detector, is becoming a standard selection for lithium electrode ear/laminate production lines due to its mounting design, ultra-thin detection accuracy, and high reliability.

From the perspective of industrial implementation, multiple lithium battery companies in Xinyu have installed dual detectors on key equipment such as slitting machines, die-cutting machines, and laminating machines. After the transformation, the equipment failure rate caused by electrode stacking has significantly decreased, and the overall equipment efficiency (OEE) of the production line has been significantly improved. During the expansion of Yichun's billion yuan industrial cluster, almost all newly built production lines are equipped with online detection equipment, and this trend is spreading throughout the entire industrial chain.

Magnetic induction dual sheet detection: selection of ultra-thin materials for lithium electrode ear/laminated production line

In the lithium battery industry, the dual detection of electrode ears and thin electrode plates is recognized as a technical difficulty - with extremely thin thickness, soft material, easy deformation, limited installation space for conventional beam detection probes, and difficulty in ensuring detection accuracy. The current mainstream technology routes include ultrasonic testing, photoelectric testing, and magnetic induction testing. Among them, magnetic induction detection has become the most widely used dual sheet detection solution in the lithium battery industry due to its high sensitivity to metal materials, immunity to dust and light environments, and adaptability to high-speed production lines.

Taking the Atorm MDSC-2100L dual detector as an example, this is a mount detection solution designed specifically for ultra-thin materials in the lithium battery industry. It adopts a single probe mounting design, and the sensor is installed closely to the side of the metal sheet material, without the need to be arranged on the upper and lower sides, especially suitable for workstations with limited internal space in laminating machines and die-cutting machines. The detection principle is magnetic induction, which accurately distinguishes between single and double sheet states through high sensitivity inductance resolution. The detection range covers ultra-thin materials of 0.1-0.5mm, fully matching the thickness specifications of lithium electrode ears and thin electrode sheets.

Supports communication and can interface with PLC and MES systems

In the practical application of lithium battery production lines, detection accuracy and installation flexibility are the core pain points. The internal space of the laminating machine is compact, and conventional aiming probes are often difficult to arrange. The placement type single probe design of Atorm MDSC-2100L perfectly solves this problem - the sensor can be attached to the side of the material channel to complete the detection, without occupying the space of the upper and lower layers, and the transformation cycle is extremely short. The detection response speed can reach 1200 pcs/min, fully covering the beat requirements of high-speed laminating production lines, and the detection accuracy is approaching full standard, effectively avoiding downstream process failures caused by pole ear double opening.

In addition, digital transformation requires testing equipment to have data interaction capabilities. MDSC-2100L supports communication interfaces and can be connected to PLC control systems and MES systems to achieve real-time uploading, storage, and analysis of detection data, providing data support for production line quality traceability and process optimization. The device is equipped with 100 sets of formula storage, and the parameters of different thicknesses and specifications of polar ear products can be switched with one click, adapting to the production characteristics of multi specification and small batch in the lithium battery industry.

From single point equipment to whole line intelligence: digital advancement of detection equipment

The digital transformation of lithium battery production lines is not an upgrade of individual equipment, but an evolution from single point detection to intelligent detection systems for the entire line. The difference between traditional detection and intelligent detection lies in three dimensions: detection coverage, data utilization, and decision-making autonomy.

Comparison dimension: Traditional detection mode, intelligent detection mode (after digital transformation)

Testing method: manual sampling+mechanical testing, online full inspection+magnetic induction intelligent testing

The detection speed is about 200-300 pcs/min, and the manual efficiency can reach 1200 pcs/min, matching the high-speed production line

Data utilization: scattered data, no systematic sedimentation, full data upload to MES, supporting quality traceability and SPC analysis

The misjudgment/missed detection rate is affected by personnel status and fluctuates greatly. The algorithm adapts to calibration and approaches full standard stability

Equipment linkage single machine operation, signal incompatibility Modbus 485 connected to the production line PLC, triggering automatic rejection

Manual adjustment of parameters for changeover efficiency, taking about 15-30 minutes to store 100 sets of formulas, one click switching, completed in seconds

From the renovation practices of 53 lithium battery companies in Xinyu, it can be seen that the input-output ratio of intelligent detection equipment is very considerable. The data of the slitting process renovation of a leading battery cell enterprise shows that after installing a magnetic induction dual sheet detector, the equipment downtime caused by the dual sheet problem decreased by more than 85%, the scrap rate of pole pieces decreased by about 40%, and the annual cost savings of a single production line exceeded one million yuan.

It is worth noting that industry leaders such as Ganfeng Lithium are accelerating the layout of solid-state battery technology. The thinner electrode plates and higher process precision requirements of solid-state batteries pose new challenges to the sensitivity and stability of detection equipment. This means that with the industrialization of next-generation battery technology, the demand for upgrading and iterating detection equipment will continue to be released, and suppliers with high-precision detection and digital interface capabilities will gain a larger market share.

The mass production of solid-state batteries is imminent, and extremely thin electrode sheets and new materials pose higher requirements for detection technology. A detection solution that can simultaneously meet high-speed, high-precision, and data interconnection requirements will take the lead in the new round of production line upgrades
