Driven by the global energy transition and carbon neutrality goals, new energy lithium batteries have emerged as the core power source for electric vehicles, energy storage systems, and smart devices. In response to the market's urgent demand for efficient, safe, and high-precision battery production, Shanghai Lanbao Sensing Technology Co., Ltd., leveraging its 27 years of expertise in industrial automation, delivers comprehensive intelligent solutions for lithium battery manufacturing, propelling the industry toward an "Intelligent Manufacturing Future."

一、Pain Points in Lithium Battery Manufacturing and Lanbao's Innovative Solutions

The production process of lithium batteries is complex, covering three major stages: the front-end (electrode preparation), the middle-end (cell synthesis), and the back-end (formation and grading). Each stage has extremely high requirements for precision, efficiency, and consistency. The traditional production model faces the following challenges:

• Difficult material deviation correction: Deviations are prone to occur during electrode coating and slitting, affecting the performance of battery cells.
• Low detection accuracy: Manual detection of welding defects, liquid level control, etc., is inefficient and prone to missed inspections.
• High safety risks: Real-time monitoring is required for equipment operation in high-temperature and high-pressure environments.

Lanbao Solutions:
Through photoelectric sensors, inductive sensors, capacitive sensors, laser ranging displacement sensors, 3D vision systems, and industrial IoT technologies, we achieve:

• Material deviation correction: ±0.2mm high-precision measurement ensures electrode sheet alignment.
• Welding inspection: 1μm-level defect recognition with a missed detection rate of <1%.
• Liquid level monitoring: Non-contact ultrasonic sensing prevents electrolyte overflow.

二、Core Application Scenarios of Full-Process Intelligence

     1.Front-End Process: Electrode Preparation

• Coater Deviation Correction: The 3D line scanning laser sensor series adjusts coating thickness in real time, enabling micron-level precise detection.
• Mixer Material Level Detection: Ultrasonic sensors/Teflon capacitive sensors monitor the liquid level of slurry in real time to prevent overflow.
• Slitter Control: Through-beam photoelectric sensors detect the slitting accuracy of electrode sheets to reduce material waste.

2.Middle-End Process: Cell Synthesis

• Winding/Lamination: Dual-sheet ultrasonic pen sensors prevent electrode sheet overlap, significantly improving production yield.
• Liquid Injection Machine Level Monitoring: Pipeline level capacitive sensors and through-beam photoelectric sensors ensure precise liquid injection volume.
• Battery Material Discharge Detection: Fiber optic sensors accurately detect material placement.

3.Back-End Process: PACK Assembly

• Cover Welding Inspection: 3D line scanning laser sensors identify welding defects at a scanning speed of 400mm/s.
• Battery Position Detection: Miniature photoelectric sensors and ultra-thin capacitive sensors achieve precise detection of battery positions on production lines.
• Battery Case Position Detection: IP67-rated inductive sensors and photoelectric sensors provide real-time detection of material arrival.
