OK-AU-390 Single-Rail PCB Receiving Machine

I. Product Introduction
This SMT PCB receiving machine, model OK-AU-390, is a large-size single-rail receiving device specifically designed for wide PCB circuit boards. The entire machine features a closed sheet metal frame with an aluminum alloy body, providing superior protection. It is equipped with a stepper motor and ball screw lifting structure, a PLC intelligent control system, and a high-definition touchscreen operation. The machine features three-point pneumatic positioning, a manual width adjustment mechanism, built-in push-board damage protection, dual audible and visual alarms, and a standard SMEMA universal interface. It operates with dual-frame cyclic operation, a 20-second rapid frame change, stable operation, and low wear. It is suitable for automated receiving of medium to large-size PCB boards and is widely used in the post-reflow soldering stage, the end of multi-process manufacturing, and the tail of component insertion lines.

III. Equipment Features

1. Basic Universality

- Intelligent Control System: Equipped with a mature PLC control system, ensuring stable continuous operation over long periods with a low failure rate, suitable for mass production in factories.

- Simple Touchscreen Operation: High-definition touchscreen HMI with built-in automatic fault diagnosis and error code prompts, easy for beginners to use.

- Multi-level Lifting: Five adjustable lifting pitches to accommodate PCBs of different thicknesses and specifications.

- Universal Interface Port: Standard SMEMA industrial communication interface for seamless integration with entire SMT automated production lines.

2. Industry Standard Features

- Widened Body Design: Adapts to PCBs up to 390mm wide, meeting the production needs of medium to large-sized circuit boards, offering wider versatility.

- Robust Body Structure: Enclosed sheet metal and aluminum alloy unibody construction, dustproof and impact-resistant, high safety protection level, and strong workshop durability.

- Precise Lifting Transmission: Stepper motor combined with ball screw drives the material frame lifting, ensuring smooth operation without vibration and accurate positioning.

- Pneumatic Precision Positioning: Three-point pneumatic clamping of the material frame prevents offset and misalignment, ensuring neat and straight board retraction.

- Convenient manual width adjustment: The track width is adjusted quickly and easily by hand-cranking a screw, adaptable to various board materials.

- Board damage protection: The built-in pusher protection system buffers the pushing force, preventing scratches and breakage of PCBs and reducing production losses.

- Multiple alarm prompts: Dual alerts—audio and visual alarms plus on-screen pop-ups—enable rapid troubleshooting of equipment malfunctions, reducing downtime.

IV. Application Scenarios

- Reflow soldering back-end: Automatically receives high-temperature PCBs from reflow soldering, replacing manual board handling, avoiding high-temperature burns, and automatically stacking them neatly, improving finished product cleanliness and production efficiency.

- Multi-process end-end: Suitable for PCB processing steps such as pattern transfer, etching, and solder masking, automatically collecting finished boards, connecting upstream and downstream processes, and ensuring smooth production line flow.

- Component assembly line back-end: Automatically collects completed component circuit boards, neatly storing them in a material frame, preparing for subsequent soldering, testing, and packaging processes, achieving automated flow.
