OK-AU-460 Extra Large 460mm PCB Width SMT PCB Unloading 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.
