The THT Axial Tape Feeder with Lead Forming is key to improving efficiency in modern PCB assembly by eliminating redundant processes. Designed to streamline this workflow, the THT Axial Tape Feeder with Lead Forming simplifies the process. This advanced feeder doesn’t simply transport unformed straight-lead components to the pick-up position; it’s a manufacturing cell in itself. It seamlessly integrates feeding, precision cutting, and U-shaped lead bending into a single, synchronized cycle. Ultimately, it continuously supplies components with shapes perfectly matched to specific PCB hole spacings, delivering them directly to the pick-up position for immediate insertion.
Speed and Precision
Speed and accuracy are non-negotiable in automated assembly. This feeder operates at a rapid cycle time of ≤0.8 seconds per component, maintaining a strict feed precision of ±0.3mm. This level of exactness ensures that every formed lead aligns flawlessly with the insertion machine’s grippers and the PCB’s pads. It is highly versatile, capable of processing a wide range of tape-packaged axial components, including resistors, diodes, and jumper wires, adapting effortlessly to diverse production requirements.
Lead Forming: Why It Matters
Axial components — resistors, diodes — must have their leads bent to match the PCB hole spacing before insertion. If the lead pitch doesn’t match the board, the component won’t seat, or worse, the insertion head forces it in and damages both the component and the PCB.
The YINUO feeder’s forming die bends leads into a U-shape with a clinch angle adjustable from 0° to 45°. The cut length is set from the insertion hole center outward — 1.2mm minimum for thin boards, up to 3.0mm for thick multilayer PCBs.
