OK-AU-460 Extra Large 460mm PCB Width SMT PCB Unloader Machine With Bidirectional Switchable Conveying And 20-Second Rapid Frame Change

OK-AU-460 Single-Rail PCB Receiving Machine

I. Product Introduction
This SMT PCB receiving machine, model OK-AU-460, is an extra-large wide-format single-rail receiving device specifically designed for large-format PCB circuit boards. The entire machine features a closed sheet metal frame with a unibody aluminum alloy construction, offering high protection and durability. It is equipped with a stepper motor + ball screw lifting structure, a mature PLC control system, and a high-definition touchscreen display. The machine comes standard with three-point pneumatic positioning clamping, a hand-cranked screw width adjustment structure, built-in push-board damage protection, dual audible and visual alarm functions, and a standard SMEMA communication interface. It adopts a dual-frame cyclic operation mode with a 20-second rapid frame change. The machine boasts stronger load-bearing capacity and stable operation, specifically designed for automated receiving of extra-large PCB boards. It is widely used in the post-reflow soldering stage, the end of multi-process manufacturing, and the tail end of component insertion lines.

III. Equipment Features
1. Basic Universal
- Stable Electrical Control System: Employs an industrial PLC control system, ensuring smooth, continuous mass production with a low failure rate, suitable for large-scale factory production.

- Intelligent Touchscreen Operation: High-definition touchscreen human-machine interface with built-in automatic fault diagnosis and clear error prompts, easy to use even for beginners.

- Multi-level Lifting Adjustment: Five adjustable lifting pitch levels, adaptable to PCBs of different thicknesses and spacings, offering strong versatility.

- Universal Communication Interface: Standard industry-standard SMEMA interface, allowing seamless connection to reflow soldering equipment, docking stations, pick-and-place machines, and other SMT production line equipment.

2. Industry Standard Features

- Extra-wide Format Compatibility: Supports PCBs up to 460mm wide, the largest size among the four models, suitable for large board and industrial circuit board manufacturers.

- High-protection Body Structure: Enclosed sheet metal and aluminum alloy unibody construction, dustproof, collision-proof, and anti-pinch, providing a higher level of workshop safety. - Precision transmission lifting: A stepper motor paired with a ball screw drives the material frame lifting, ensuring smooth, quiet, and vibration-free operation with zero positioning deviation.

- Pneumatic precision positioning: A three-point pneumatic clamping structure firmly locks the material frame in place, preventing large boards from shifting or tilting during storage.

- Easy manual width adjustment: A hand-cranked screw adjusts the track width, requiring no tools and quickly adapting to various large boards.

- Board damage protection: A built-in push-plate buffer protection system prevents large boards from being pushed, cracked, or scratched, significantly reducing production scrap costs.

- Intelligent multi-alarm system: Dual alarms—audio-visual warning and screen pop-up—provide real-time alerts for missing boards, frame jamming, and abnormal air pressure, facilitating maintenance and troubleshooting.

IV. Application Scenarios

- Reflow soldering back-end: Automatically receives large boards exiting the high-temperature reflow oven, replacing manual board removal, avoiding burns from high temperatures, and automatically and neatly stacking boards, improving the tidiness of large board storage and saving labor costs.

- Multi-process end-of-line: Suitable for PCB deep processing steps such as pattern transfer, etching, and solder masking. It automatically collects finished large-format circuit boards, connecting various process lines to ensure uninterrupted production.

- Component assembly line end-of-line: Automatically collects finished large-format circuit boards after component assembly, neatly placing them into material frames for subsequent testing, aging, soldering, and packaging processes.

This unit handles the automatic loading and unloading of PCBs in SMT lines. It cuts down on manual board handling, reduces the chance of ESD or mechanical damage, and keeps the line moving at a steady pace. Works with single and dual-lane conveyor setups.
