Application Case: Application of Yudian AI-7xx8 Series Products in Photovoltaic Lamination Stringing Machine Equipment

Product Model Used: AI-7xx8 Multi-Channel Temperature Control Module

Process Overview:
The direct lamination stringing machine is capable of achieving the serial connection function for conventional TOPCon and HJT busbar-free solar cells. It addresses issues such as micro-cracks, broken grids, and short circuits caused by traditional soldering. Additionally, it solves micro-crack problems at small and negative spacing layers through flexible interconnection technology, eliminating the need for fluxes and effectively avoiding structural aging, flux contamination, and electrode corrosion. With flexible transport mechanisms and precise control systems, this equipment achieves a one-time flexible interconnection of solar cells, ribbons, and front and backside encapsulation films.

On-Site Application Details:
The heating method used in the direct lamination stringing machine is infrared low-temperature heating, with numerous temperature control points on the equipment using PT100 sensors for temperature measurement. After startup, the machine needs to quickly heat up to 100°C and then maintain a constant temperature. Rapid heating and stable temperature control are critical to ensuring the capacity of the equipment.

Problems Solved for Customers:
The Yudian AI-7xx8D71 temperature control module features excellent rapid response capabilities, achieving temperature rise from room temperature to production requirements within five minutes, and maintaining constant temperature control, thereby meeting various production needs. Through precise temperature control algorithms, Yudian's temperature controllers ensure minimal temperature fluctuations during production, providing a stable working environment for the one-time flexible interconnection of solar cells, ribbons, and front and backside encapsulation films. Multi-channel temperature control allows independent control of each channel, ensuring suitable solutions for different temperature points controlled by customers' various equipment.

Customer Feedback:
We previously used other brands of temperature control modules on our equipment. The control effect of Yudian’s AI-7xx8 temperature control module is significantly better than previous solutions. Key materials are 100% domestically produced, ensuring stable supply. Small batch orders can be delivered within five working days, enabling zero-inventory procurement without pressure.
