Smart Nan'an · Collaborative Innovation: Nan'an Science and Technology Achievement Supermarket Express Enters Industry-University-Research Collaboration, Aisirui Technology Empowers Upgrades with X-Ray Intelligent Inspection

On April 17, 2026, the "Scholarly Excellence, Smart Nan'an" Enterprise Leading Talent Technology Matchmaking Salon was successfully held at the Nan'an Science and Technology Innovation Talent Center.

This Salon aimed to establish an efficient matchmaking platform between Xiamen University and Nan'an's equipment manufacturing industry. Hardcore technology teams from Xiamen University, including Aisirui Technology, Professor Liu Juan's team, and Xuanwei Technology, gathered together. They focused on introducing cutting-edge achievements such as X-ray intelligent inspection, intelligent laser welding, and intelligent vision inspection directly into the production frontline, helping enterprises address their practical needs for technological breakthroughs and production capacity enhancement.

I. Building a "Perception-Control" Closed Loop for Welding
Associate Professor Liu Juan's Team Shared the Intelligent Laser Welding System

Dr. Chu Zhaoqi, a member of Associate Professor Liu Juan's team, presented the "Intelligent Laser Welding Robot System with Integrated Visual Sensing."

Leveraging Xiamen University's Micro-Nano Systems and Intelligent Sensing Laboratory and collaborating with the National Engineering Research Center for Laser Processing at Huazhong University of Science and Technology, the team has achieved breakthroughs in multi-phase structured light sensors, complex weld seam recognition, robot trajectory planning algorithms, and welding process integration.

The system deeply integrates laser welding with visual sensing, enabling real-time recognition of weld seam position and morphological changes, and automatically adjusts welding paths and process parameters, forming a "perception-control" closed loop. Compared to traditional manual experience-dependent welding, this technology demonstrates superior performance in scenarios such as processing complex structural parts and non-standard components, providing a feasible path for enterprises to achieve welding automation and precision control.

II. Seeing Through Internal Quality: X-Ray Inspection Becomes a Key Link
Aisirui Technology Highlighted X-Ray Intelligent Inspection Technology

Li Shunren, General Manager of Aisirui Technology and a member of Professor Fang Zheng's team, delivered a systematic presentation on "X-Ray Intelligent Inspection Technology."

Breaking Monopoly with Independent and Controllable Core Technology

Aisirui Technology, founded by the team of Professor Fang Zheng from Xiamen University, is an enterprise resident in the Xiamen University Science Park Nan'an Park. The team's independently developed X-ray intelligent inspection technology has broken the foreign technology monopoly. Its core products include CT/DR dual-mode inspection equipment, automatic flip bidirectional scanning systems, and production-line CT equipment.

From "Surface Inspection" to "Internal Visualization"

During manufacturing, internal defects such as pores, voids, inclusions, and cold solder joints are difficult to detect with the naked eye or conventional inspection methods. X-ray inspection technology non-destructively reveals the internal structure of products, making hidden quality issues "visible." This technology overcomes the limitations of traditional appearance-based inspection, extending quality control from "surface inspection" to "internal visualization," providing more comprehensive assurance for product reliability.

Precisely Aligning with Key Industries in Xiama Town

Considering the industrial characteristics of Xiama Town, Nan'an, this technology can be widely applied in:

• Communications Equipment Industry: Inspection of internal circuit board soldering in products such as two-way radios, and defect detection in electronic component packaging.

• Machinery Equipment Industry: Evaluation of internal porosity, cracks, and weld quality in cast components such as the "four wheels and one track" (undercarriage parts) of construction machinery.

• Auto Parts and New Energy Vehicle Industry: Defect detection in key components such as battery modules, motor housings, and controllers.

• Optoelectronics Information Industry: Internal structure analysis of products such as precision optical components, sensors, and semiconductor packages.

As a key promoted technology at this salon, Aisirui Technology is deeply engaging with manufacturing enterprises in Xiama Town and the broader Nan'an area, bringing cutting-edge inspection technology directly to the production frontline and helping to upgrade and improve the quality of Nan'an's equipment manufacturing industry.

III. Improving Appearance Inspection Efficiency and Consistency

Xuanwei Technology Shared Intelligent Vision Inspection Technology

Tu Yan, General Manager of Xuanwei Technology and a member of Associate Professors Liu Yunlong and Wang Xin's team, delivered a presentation on "Intelligent Vision Inspection Technology."

Xuanwei Technology is advised by Associate Professors Liu Yunlong and Wang Xin from the School of Aerospace Engineering at Xiamen University. The team possesses deep technical expertise in areas such as artificial intelligence, deep reinforcement learning, and intelligent decision-making. The intelligent vision inspection system developed by the company, through image acquisition and algorithmic processing, can quickly identify common surface defects such as scratches, stains, and dimensional deviations on products. It features high inspection speed and high consistency, effectively replacing traditional manual visual inspection and reducing errors and instability.

Currently, this technology has been adapted to meet the quality inspection needs of industries such as electronics manufacturing and precision machining. Having completed small-scale pilot validation, it is now accelerating efforts to help manufacturing enterprises in Nan'an achieve intelligent upgrades.

Building a Platform to Facilitate Technology Transfer

This event, relying on the Nan'an Science and Technology Achievement Supermarket Express platform, built a communication bridge between university research teams and enterprises. Through concentrated presentations and on-site exchanges, it promoted the transition of technological achievements from the laboratory to practical application scenarios.

From welding to inspection, from internal structure to surface quality, the concentrated presentation of multiple key technologies has provided a clear path for the transformation and upgrading of the manufacturing industry and laid a solid foundation for further in-depth cooperation.

In the future, as more technological achievements are continuously transferred and implemented, industry-university-research collaborative innovation will continue to unleash new drivers of development.
