Auto-Return SMT Carrier Reflow Line: PLC-Controlled Closed-Loop System

Auto-Return SMT Carrier Reflow Line is engineered to eliminate manual intervention between production stages, creating a seamless and efficient closed-loop reflow system. Designed for modern smart factories, this system automatically manages the entire journey of your JG cover plates or similar carriers—from automatic docking with upstream equipment to transport, transfer, buffering, and flipping.

By integrating a high-performance PLC (Programmable Logic Controller) and a sophisticated recipe management system, this line enables true flexible manufacturing. You can save all parameters for a specific product with a single click and switch programs instantly, making high-mix, low-volume production both practical and profitable.

Product Advantages

Intelligent PLC Control & One-Touch Recipe Management
At the heart of the system is a robust industrial PLC that ensures precise sequential control and high reliability. Our unique selling point is the powerful recipe management system. Operators can set and fine-tune parameters for different products—such as conveyor speed, transfer timing, and flip sequence—and save the entire program with one-touch program saving. This feature slashes product changeover times and completely eliminates human error in recipe recall.

Fully Automated Closed-Loop Reflux Workflow
This line is designed for end-to-end automation, forming a continuous closed-loop reflux that significantly saves manpower. Its integrated functions include:

Automatic Docking & Transport: Ensures smooth and continuous pickup and movement of carriers from preceding machines.

Automatic Rotation & Transfer: Precisely orients and moves carriers to the correct position for the next process.

Automatic Buffering: A built-in caching system prevents bottlenecks and maintains a continuous production flow, even during asynchronous line operations.

Automatic Flipping: Performs flip operations for double-sided assemblies or specific process requirements without manual handling.

Built for Modern SMT Challenges
Constructed with compatibility for advanced processes like lead-free soldering, this system helps you meet stringent global environmental standards. Its robust design is also suited for integration with nitrogen reflow ovens, ensuring high-quality soldering results for demanding applications in automotive, telecommunications, and consumer electronics.

User-Centric HMI & Smart Factory Readiness
The system is operated via an intuitive touchscreen HMI (Human-Machine Interface), making monitoring and control straightforward. With its open architecture, the equipment is prepared for data exchange and integration into broader Industrial IoT (IIoT) and smart factory ecosystems, enabling real-time production monitoring and analysis.
