Amid fierce competition in the semiconductor display industry, controlled clean production environments constitute a core barrier guaranteeing product quality. As a key domestic player in the new display sector, Mianyang HKC Optoelectronics Technology Co., Ltd. (“Mianyang HKC”) consistently drives growth through technological innovation. To further elevate environmental management standards in its workshops, Mianyang HKC has deployed self-developed intelligent inspection robots from Suzhou Kangqi Environmental Technology Co., Ltd. (“Kangqi Environmental”). This deployment establishes an unmanned, round-the-clock, high-precision cleanliness monitoring system that lays a solid foundation for high-quality manufacturing of semiconductor display panels.

Pain Points of Traditional Inspection and Opportunities for Innovation

Semiconductor display panel manufacturing demands extremely stringent cleanliness standards, requiring workshops to meet ISO Class 5 (Class 100) or higher cleanroom classifications.

Traditional manual inspection is hampered by three major limitations:

1. Low Efficiency: Manual inspection cycles are lengthy and heavily reliant on staff conditions, making high-frequency monitoring unfeasible.

2. Insufficient Precision: Manually operated testing equipment is prone to human interference, failing to capture real-time dynamic variations of micron-sized dust particles accurately.

3. High Operating Costs: Personnel entering high-grade cleanrooms must complete elaborate decontamination procedures, resulting in sustained high labor expenditures.

To address these widespread industry challenges, Mianyang HKC took the lead in deploying Kangqi Environmental’s intelligent inspection robots across its workshops, delivering three major upgrades to cleanliness monitoring:

· Inspection Frequency: Shift from monthly scheduled manual checks to daily automated robot patrols

· Detection Precision: Eliminate secondary contamination introduced by human operators

· Monitoring Parameters: Upgrade from standalone particle counting to integrated multi-parameter analysis covering particle concentration, temperature, humidity and airflow

Kangqi Environmental Intelligent Inspection Robot

The core competitiveness of Kangqi Environmental’s intelligent inspection robot stems from its three-in-one technical architecture:

1. Autonomous Navigation & Flexible Obstacle Avoidance System

· Dual-redundancy track-and-vision navigation: The robot travels along pre-installed tracks while equipped with LiDAR and visual recognition modules to identify millimeter-scale obstacles and reroute automatically for uninterrupted patrols.

· High-precision positioning: Powered by SLAM (Simultaneous Localization and Mapping) technology, it achieves positioning accuracy of ±10 mm to ensure measurements are taken at exact designated sampling points.

2. Multi-dimensional Environmental Sensing System

· Airborne particle monitoring: Compatible with the full range of Kangqi particle counters, covering particle sizes from 0.1 μm to 500 μm and sampling flow rates of 2.83 LPM to 100 LPM to accommodate diverse cleanroom application scenarios.

· Linked temperature & humidity monitoring: Integrated high-precision temperature and humidity sensors collect real-time environmental data to guide adjustments for cleanroom HVAC systems.

· Airflow condition analysis: Wind speed and air pressure sensors detect airflow turbulence zones to support optimized ventilation layout design within workshops.

3. Intelligent Data Analysis & Early Warning Mechanism

· Cloud data platform: Real-time data collected by robots is synchronized to the cloud, where algorithms build correlation models linking cleanliness levels and equipment parameters to forecast potential contamination risks.

· Multi-tier alarm system: Three threshold levels (Warning, Alert, Critical Alert) trigger automatic audio-visual notifications once particle concentrations exceed set limits.

· Visualized management dashboard: A 3D map displays live inspection results, allowing administrators to remotely access environmental parameters at any sampling point and generate historical data reports on demand.

From Passive Troubleshooting to Proactive Risk Prevention

Mianyang HKC’s on-site application demonstrates remarkable benefits brought by Kangqi Environmental’s intelligent inspection robots:

Boosted Operational Efficiency

· Higher inspection frequency and full coverage of workshop floor space

· Abnormality response time cut from days down to minutes

Strengthened Quality Assurance

· Higher cleanroom compliance rate and monthly product yield

· Reduced defective products caused by particulate contamination, lowering quality-related costs

Optimized Cost Structure

· Fewer manual inspection positions, cutting labor costs

· Precise regulation of purification equipment to reduce energy consumption

Building an Intelligent Cleanroom Ecosystem

As research and development of next-generation display technologies advance, Mianyang HKC’s cleanliness requirements will grow even more rigorous. Kangqi Environmental and Mianyang HKC are jointly exploring full-process automated control spanning monitoring, air purification and production operations.

Far more than a mere testing instrument, Kangqi Environmental’s intelligent inspection robot acts as a critical enabler of smart manufacturing. It transforms passive particle detection into active quality control, injecting robust momentum into Mianyang’s goal of building a leading new display industrial hub in western China.

Against the backdrop of the semiconductor display industry’s shift toward refined and intelligent manufacturing, the partnership between Mianyang HKC and Kangqi Environmental sets an industry benchmark. Driven by technological and managerial innovation, the two enterprises are writing a new chapter of technology-enabled clean manufacturing.
