Pneumatic torque reaction arm with integrated absolute encoder

1. Solution Overview

In modern manufacturing and assembly lines, ensuring accurate torque and preventing any missed screws are critical factors determining product quality. The pneumatic assist positioning torque arm is a powerful support device specifically designed to solve this challenge. By combining a smooth pneumatic assist system with advanced absolute encoder technology, the product not only reduces operator fatigue but also provides complete control over the screwdriving process. The device accurately positions coordinates (x,y), manages tightening sequences, and synchronizes signals to thoroughly prevent missing screws (Poka-Yoke).

2. Key Features & Highlights

• Precise Coordinate Positioning: Built-in absolute encoders on the joints continuously transmit position data, allowing accurate mapping of screwdriving points.
• Sequence Control: The system only allows tool operation when the screwdriver bit is at the exact next coordinate. Prevents out-of-sequence operations and ensures process compliance.
• Missing-Screw Prevention (Poka-Yoke): Synchronized with the electric screwdriver. A point is only marked “OK” when at the right coordinate and the tool confirms target torque is reached. Eliminates the risk of missed screws.
• Ergonomic Optimization: Pneumatic cylinder assistance counterbalances the tool weight. Enables effortless, flexible operation and reduces operator fatigue.

3. Structure & Included Accessories

• Solid Aluminum Alloy Frame: CNC-machined, rigid construction.
• Signal Connection Cable: Includes standard USB/DB cable.
• Pneumatic Pressure Regulator Unit: Includes pressure gauge.
• Flange Base: Workbench-mounted, includes mounting screw kit.
