In the SMT (Surface Mount Technology) process, the speed of insertion machines is crucial for enhancing productivity. Many manufacturers are actively seeking ways to increase the speed of these machines. Based on years of experience, we have summarized several key methods to improve the speed of insertion machines and feeders:
1. Structural Improvements of Insertion Machines
Implementing multi-head combination technology is essential. Current designs include dual-head, quad-head, and six-head configurations that utilize a truss structure with simultaneous drive at both ends. This design prevents cantilever effects and reduces mechanical stabilization time. Additionally, modular multi-unit structures emphasize the insertion speed per unit area.
2. Motion Drive and Linear Motor Technology
Utilizing fuzzy control technology allows for three-stage motion control—“slow, fast, slow”—creating an S-shaped velocity profile. This approach ensures that movements are both gentle and rapid.
Linear motors, known for their high positioning accuracy and repeatability, can achieve high speeds and accelerations (up to 55 ms). They operate with low working currents, enabling precise control and stability.
3. Rapid Detection Technology
The application of laser and CCD (Charge-Coupled Device) technology in conjunction with dual cameras allows for separate detection of chip components and large ICs (Integrated Circuits). This setup facilitates rapid image acquisition and circuit conversion.
4. Feeder Technology
Automated feeders streamline the component supply process, significantly reducing changeover times and minimizing human errors. Features such as non-stop material changes, dual-belt feeders, and large-capacity feeders (with some insertion machines accommodating up to 256 eight-millimeter feeders) enhance efficiency in bulk feeding. Simultaneous feeding from multiple feeders reduces loading times and increases overall capacity.
5. Software Technology
Advanced software solutions enable direct optimization of insertion program files from various PCB formats, reducing manual programming time. Additionally, optimized self-diagnostic systems for machine faults and comprehensive production management systems contribute to efficient and intelligent operations.
Conclusion
By focusing on structural improvements, advanced motion control technologies, rapid detection methods, efficient feeder systems, and sophisticated software solutions, manufacturers can significantly enhance the speed of insertion machines and feeders. These improvements lead to increased productivity and operational efficiency in the SMT manufacturing process.
At YEETAI, we produce all kinds of feeder to upgrade SMT machines.
