I. Background and Pain Points

With the rapid development of new energy vehicles and energy storage industries, lithium battery production demands increasingly stringent dimensional accuracy. Traditional measurement methods exhibit significant shortcomings, such as:

01. Micrometers: While meeting some precision requirements, they involve cumbersome operations and low efficiency. Contact-based measurement risks scratching battery casings, impacting yield rates.

02. Rulers/Calipers: Precision is limited to the millimeter level, failing to meet control requirements within ±0.5mm, and cannot support automated batch inspection.

To resolve this challenge, the industry urgently requires an online measurement solution that combines high precision, high efficiency, and non-contact operation.

II. Measurement Solution: HM Series Telecentric Measurement System

The HM Series Telecentric Measurement System employs non-contact optical imaging technology. By integrating high-resolution industrial cameras with intelligent algorithms, it achieves measurement accuracy at the 1-micron level—far exceeding the industry standard requirement of ±0.5mm.

1. Nanometer-level precision assurance: High-resolution industrial cameras and AI algorithms precisely capture cylindrical battery diameter, height, tab position, and surface defects, eliminating assembly failures caused by dimensional deviations.

2. Ultra-fast response capability: Single-measurement cycles complete in just 35 microseconds, enabling millisecond-level full inspection on automated production lines to dramatically boost efficiency.

3. Intelligent Sorting Integration: Automatically identifies non-conforming products and triggers rejection mechanisms, reducing manual re-inspection costs and minimizing missed defect risks;

4. Flexible Deployment: Supports rapid switching between multiple cylindrical battery models, accommodating various specifications (e.g., 18650, 14500) to meet diverse home appliance remote control requirements.
