The HDY-250LSB1 L-Type PCB Unloader​ is a highly efficient automated terminal equipment designed for the end of SMT production lines. Specifically engineered for collecting PCBs after reflow soldering or other high-temperature processes, it ensures safe and orderly unloading. The machine features a robust aluminum guide rail system and durable "thousand-bird" plastic chains. It is driven by a 90W brake motor​ combined with a precision ball screw, enabling smooth and accurate step lifting of the magazine. Equipped with an air clamp structure​ and an Inovance PLC controller, it guarantees stable and precise operation. The intuitive Xinguang true-color touch screen​ simplifies parameter settings and real-time monitoring, while the built-in 0.65M push plate conveyor​ facilitates seamless PCB transfer to the next process or storage area.

Compared to conventional unloaders on the market, the HDY-250LSB1 stands out with the following advantages:

• High-Capacity & Stable Unloading:​ With a 50-PCS magazine capacity, it significantly reduces manual intervention. The combination of a 90W brake motor and ball screw drive ensures stable lifting without slippage or jamming.
• Precise Control & Durability:​ Utilizing aluminum alloy guide rails​ and high-quality "thousand-bird" plastic chains, it offers superior wear resistance and a longer lifespan compared to standard steel chains.
• Smart & User-Friendly Operation:​ The Inovance PLC​ with a true-color touch screen​ provides a clear interface for easy operation, automatic alarm functions, and quick troubleshooting, reducing operator training time.
• Flexible Configuration:​ The lift platform pitch is selectable at 10mm, 20mm, 30mm, or 40mm, adapting to various PCB thicknesses and production line requirements. The standard Left-to-Right​ direction can be customized.
• Reliable Components:​ Integrated with Mingwei power supplies​ and Omron relays, ensuring high electrical stability and safety for 24/7 continuous operation.

This L-Type unloader is an essential component for:

• SMT Production Lines:​ Specifically used for unloading PCBs after reflow ovens, ensuring they are cooled and collected efficiently.
• PCB Assembly Factories:​ Ideal for high-volume production environments where manual unloading would cause bottlenecks.
• Electronics Manufacturing Services (EMS):​ Suitable for factories requiring high throughput, precision, and minimal human error.
• Automated Factory Integration:​ Works seamlessly with upstream pick-and-place machines and downstream inspection/aging equipment to form a complete automated line.
