OK-LX-330 Widened L-Shaped PCB Feeding Machine

I. Product Introduction
The OK-LX-330 widened L-shaped PCB feeding machine is a specialized automatic feeding device for large-size PCBs, commonly known in the industry as a board feeder or material handler. The machine adopts a popular industrial L-shaped corner structure, specifically designed for production line bends, solving the problems of limited workshop space and restricted straight production line layouts. The entire machine uses a sheet metal and aluminum alloy unibody sealed design, making it robust, durable, dustproof, and preventing accidental contact, with a high level of safety protection. It features a stepper motor and ball screw lifting structure, combined with a mature PLC programmable control system, ensuring uniform board output and minimal vibration. The machine has a built-in dual-frame rotation station, allowing frame changing operations without stopping the machine, continuously supplying boards to downstream equipment. Optimized for large-size circuit boards, the pushing logic includes built-in buffer push protection, effectively preventing bending, chipping, and scratches on large boards. It is widely compatible with automated production lines for medium to large-size PCBs and is a universal automated feeding device for SMT, DIP, and inspection processes.

- Bidirectional Compatible Conveying Mode: Supports bidirectional conveying, not limited by production line layout. Can be directly connected to both new and old production lines without modifying the production line layout. - Multi-level alarm reminders: Integrated audible and visual alarms + screen pop-up alarms provide timely alerts for issues such as board jamming, board shortages, misaligned material frames, and insufficient air pressure, preventing production accidents.

- Universal SMEMA interface port: Industry-standard interface, seamlessly compatible with printing presses, pick-and-place machines, wave soldering machines, inspection equipment, and other SMT production lines.

2. Industry standard configuration

- Customized specifications for large PCBs: Specifically developed for wide PCBs, supporting boards up to 330mm wide and 450mm long, offering a larger sized fit than standard board loading machines and broader industry applicability.

- Sealed safety protection body: Fully enclosed sheet metal + aluminum alloy frame structure, impact-resistant, dustproof, and prevents accidental contact. Durable even in harsh workshop environments.

- Precision ball screw uniform lifting: Stepper motor precisely drives the ball screw, ensuring smooth and uniform lifting of the material frame, preventing board tilting or shaking, and ensuring accurate loading position.

- Large-board dedicated pusher protection: Optimized buffer pushing structure for flexible pushing of large-sized thin and rigid boards, preventing bending and cracking under stress, significantly reducing process scrap rate.

- Three-point pneumatic locking positioning: Three-point pneumatic clamping of the material frame ensures a stable and non-shifting lock, preventing shaking during heavy-duty large-board operation and ensuring consistent output position for each board.

- Manually cranked mechanical fine-tuning track: Manually adjustable track width with uniform damping and secure locking, adaptable to medium and large-sized circuit boards of varying thicknesses.

- Dual-frame uninterrupted continuous feeding: Working and spare material frames operate alternately, with a rapid 20-second frame change, eliminating the need for manual stopping for refueling and ensuring uninterrupted production line operation.

- Multi-level pitch adjustment: Five adjustable lifting pitches allow for free switching, compatible with different slot spacing material frames, meeting the feeding needs of various production processes and different board types.

IV. Application Scenarios

- SMT (Surface Mount Technology) Production Line Adaptation: Placed at the front end of the solder paste printer, it automatically and neatly conveys large-size PCB substrates, feeding them at a uniform speed to the pick-and-place machine to complete component placement, soldering, and assembly processes, achieving unmanned material handling on the SMT production line.

- DIP (Digital In-line Package) Production Line Adaptation: Located at the front end of the through-hole processing step, it automatically conveys the completed circuit boards and smoothly feeds them into the wave soldering equipment for soldering, replacing manual handling and board loading, saving manpower.

- Testing and Packaging Production Line Adaptation: Can be installed at the front end of testing equipment, automatically supplying materials to ICT (In-Circuit Tester), FCT (Functional Tester), and packaging equipment, completing the entire process of circuit board testing, sorting, and packaging.

- Adaptation for Narrow Corner Workstations: The L-shaped corner structure has a moderate footprint, suitable for placement in factory corners and narrow workstations, making full use of idle dead space and optimizing workshop production line layout.
