Multi-Spindle Screw Fastening Machine with Torque Control for Mobile Phone Assembly
In mobile phone assembly, the screw fastening process demands both high efficiency for mass production and extreme precision to protect delicate components. The Multi-Spindle Screw Fastening Machine with Torque Control perfectly meets these dual requirements, integrating the simultaneous operation advantage of multi-spindle design and the precise force control of torque control to deliver consistent, high-quality assembly results for mobile phone casings, motherboards, and camera modules.
Multi-Spindle Design: Doubling Assembly Efficiency
The multi-spindle configuration is the key to boosting efficiency in mobile phone assembly. Unlike single-spindle machines that fasten one screw at a time, this machine features 4–8 synchronized spindles (configurable according to needs), enabling simultaneous fastening of multiple screws on a single mobile phone component. For example, it can complete the fastening of 6 screws on a camera module in one cycle, reducing the process time by 60% compared to single-spindle equipment. This parallel operation mode effectively eliminates production bottlenecks, making it ideal for high-volume mobile phone manufacturing lines that require rapid throughput.
Torque Control: Safeguarding Component Integrity
Torque control is critical for protecting the fragile components of mobile phones during screw fastening. Mobile phone parts such as plastic casings and circuit boards are highly sensitive to excessive force—over-tightening can cause cracks or circuit damage, while under-tightening leads to loose assembly. This machine adopts high-precision servo torque control technology, with an adjustable torque range of 0.05–2 N·m and a torque accuracy of ±3%. It real-time monitors and feeds back the fastening torque, ensuring each screw is tightened to the exact specification. The built-in torque alarm function triggers an alert immediately if the torque deviates from the set range, preventing defective products from entering the next process.
Mobile-Focused Optimization: Enhancing Adaptability
The machine is specially optimized for mobile phone assembly scenarios. It features a compact structure that fits seamlessly into existing mobile phone production lines, with a flexible positioning system that adapts to different mobile phone models and component sizes. The quick-change spindle design allows for easy switching between different screw sizes (M1–M3, the most common in mobile phones) in minutes, reducing downtime for model changes. Additionally, the integrated automatic screw feeding system ensures a continuous and stable supply of tiny screws, avoiding manual handling errors and further improving assembly efficiency and consistency.
In summary, the combination of multi-spindle efficiency, torque control precision, and mobile-focused optimization makes this machine an indispensable tool for mobile phone assembly. It provides the speed, accuracy, and reliability required to meet the strict quality and efficiency standards of modern mobile electronics manufacturing.
