OK-LX-330S Widened L-type PCB Unloader with 50-330mm PCB Width Dual-Frame Alternating Operation And PLC Intelligent Control

OK-LX-330S Widened L-Type PCB Receiving Machine

I. Product Introduction
The OK-LX-330S is a widened L-type SMT PCB receiving machine, also commonly known as a board unloading machine or material receiving machine, specifically designed for large-size PCB circuit boards. The machine adopts a classic L-shaped corner structure, adapting to corner connections on production lines and saving workshop space. The entire machine uses a sheet metal and aluminum alloy enclosed body, equipped with a stepper motor and ball screw lifting structure and a PLC intelligent control system, ensuring stable and low-noise operation. It features a dual-frame alternating operation mode, eliminating the need for frame changes and automating board picking, effectively reducing labor costs and board breakage. Suitable for medium to large-sized PCB production lines, it is versatile, durable, and easy to maintain.

- Universal Communication Interface: Standard industrial SMEMA interface, seamlessly connects to reflow soldering, docking stations, production lines, and other SMT equipment.

2. Industry Standard Features

- Widened Custom Specifications: Adapts to boards up to 330mm wide and 450mm long, offering wider applicability compared to conventional board take-up machines, and is suitable for large-size PCB production.

- Precision Screw Lifting: Stepper motor drives the ball screw, ensuring smooth and uniform lifting of the material frame with precise positioning, free from vibration and offset.

- Damage-Proof Pushing Protection: Unique push-board buffer protection system prevents hard compression of PCB boards, significantly reducing scratches and breakage.

- Pneumatic Precision Positioning: Three-point pneumatic clamping of the material frame ensures stable, wobbly, and neat stacking without misalignment.

- Enclosed Industrial Body: Sheet metal and aluminum alloy integrated sealed structure provides dust and impact protection, high safety level, and durability in the workshop.

- Hand-Cranked Micro-Adjustable Track: Hand-cranked screw adjusts the width smoothly and securely, adapting to various circuit board thicknesses.

- Uninterrupted Material Changeover: Dual material frames work alternately, with a rapid frame changeover in 20 seconds, eliminating downtime and preventing production line congestion.

IV. Application Scenarios

- Reflow Soldering Back-End Material Collection: Automatically and neatly collects high-temperature PCBs from reflow soldering, replacing manual handling and preventing burns, board bending, and surface contamination, thus improving finished product quality.

- PCB Process Mid-Stage Connection: Suitable for use after processes such as pattern transfer, etching, and solder masking, automatically collecting semi-finished boards and connecting upstream and downstream processes to ensure smooth and uninterrupted production line operation.

- Component Insertion Line End-End Board Collection: Automatically collects circuit boards after component insertion processing, neatly storing them in material frames, preparing them for subsequent soldering, inspection, and packaging processes.

- Corner Station Adaptation: L-shaped corner structure, suitable for installation in workshop corners and narrow workstations, saving factory space and adaptable to various small and medium-sized SMT assembly lines.
