OK-LX-250S Standard L-Type PCB Receiving Machine

I. Product Overview
The OK-LX-250S is a standard L-type PCB receiving machine, also commonly known as a board unloading machine or material receiving machine, specifically designed for small to medium-sized standard-sized PCB circuit boards. The machine adopts an L-shaped corner structure, adapting to corner connections on production lines, cleverly utilizing dead space in the workshop and reducing site occupation. The entire machine uses a sheet metal + aluminum alloy enclosed structure, equipped with a stepper motor ball screw lifting system and a PLC intelligent control system, ensuring smooth operation, low noise, and a low failure rate. The machine features a dual-frame alternating working mode, allowing for a 20-second rapid frame change without machine downtime, fully automatically completing the PCB board collection and stacking, replacing manual board picking, effectively reducing labor costs, avoiding human-caused damage to the boards, and adapting to various small to medium-sized SMT assembly lines. It is highly versatile, durable, and easy to maintain.

- Multiple Safety Alarm Mechanisms: Equipped with audible and visual alarms + screen pop-up alerts, providing timely warnings for missing boards, board jams, and material frame malfunctions to avoid production accidents.

- Universal Industrial Communication Interface: Standard SMEMA interface, seamlessly connecting to reflow soldering equipment, connecting tables, board loading machines, and other SMT production line equipment.

2. Industry Standard Features

- Enclosed Industrial Body: Sheet metal combined with an aluminum alloy enclosed structure provides dustproof, impact-resistant, and hand-pinch-proof protection, offering a high level of safety and enabling long-term use even in harsh workshop environments.

- Precision Ball Screw Lifting Structure: A stepper motor drives a ball screw to lift the material frame, ensuring quiet and smooth operation, precise positioning without deviation, and neat stacking of boards.

- PCB Damage Prevention and Push-Board Protection: An integrated push-board buffer protection system prevents the hard pushing and squeezing of circuit boards, eliminating board breakage and scratches, significantly reducing production losses.

- Three-Point Pneumatic Precision Positioning: A three-point pneumatic clamping design firmly locks the material frame in place, preventing shaking and deviation during operation.

- Hand-Cranked Mechanical Width Adjustment: A hand-cranked ball screw adjusts the track width smoothly and securely, adapting to various thicknesses of standard PCB boards.

- Dual-Frame Continuous Operation: A dual-frame design with one working and one waiting frame allows for rapid automatic frame changing in 20 seconds, eliminating the need for standby and ensuring continuous production on the assembly line.

- Multi-level pitch adjustment: Supports five pitch adjustments from 10-50mm, adaptable to different material frames and production processes, offering greater versatility.

IV. Application Scenarios

- Reflow Soldering Back-end Material Collection: Specifically designed to handle high-temperature PCBs from reflow soldering, automatically and neatly collecting and stacking them, replacing manual handling, eliminating burns, oil stains on the board surface, and board bending, effectively improving finished product quality.

- PCB Process Mid-stage Connection: Suitable for the back-end of processes such as pattern transfer, etching, and solder masking, automatically collecting semi-finished circuit boards, connecting upstream and downstream production processes, ensuring smooth and uninterrupted production line operation.

- Component Insertion Line End-end Board Collection: Automatically collects circuit boards after component insertion processing, neatly storing them inside the material frame, preparing for subsequent soldering, functional testing, and packaging.

- Workshop Corner Station: L-shaped corner structure, compact size and small footprint, suitable for installation in small workshops and corner stations, making reasonable use of dead space in the factory.
