1. Product Introduction

The HDY-250/330LSB1 L-Type PCB unloader, also known as magazine PCB collector, is a professional end-of-line unloading equipment for automated SMT assembly lines. It automatically receives finished PCBs from upstream machines and stacks them into magazines, realizing continuous unmanned board collection and greatly improving line efficiency. The machine adopts a special aluminum profile guide rail with a special crossover plastic chain for stable magazine conveying. A 90W Taiwan-made brake motor drives the ball screw to realize precise stepping lift of the magazine, with platform pitch selectable at 10, 20, 30 or 40mm according to PCB thickness. The pneumatic clamping structure firmly fixes the magazine to prevent displacement during operation. An attached 0.75M long pusher conveyor smoothly delivers PCBs into the magazine. It is controlled by Inovance PLC with an intuitive Xinje true-color touch screen for easy operation and parameter setting. Two magazine specifications are supported: L355*W320*565mm and L460*W400*565mm, with maximum PCB size L450*W330mm and full-load storage capacity of 50 PCS. Power supply 220V 50Hz, air pressure 0.4-0.6MPa, transport direction left to right, complete electrical control cabinet and Mean Well power supply with Omron relays for stable long-term operation.

2. Advantages Over Competitors

1. Dual magazine size compatibility — supports both L355*W320*565mm and L460*W400*565mm magazines, covering more production scenarios than single-size machines.
2. 90W Taiwan-made brake motor + ball screw stepping lift — high positioning accuracy with brake function preventing magazine dropping; more stable than common stepper-only lifting systems.
3. Adjustable platform pitch (10/20/30/40mm) — flexibly matches different PCB thickness and stacking requirements.
4. 0.75M pusher conveyor included as standard — no extra purchase of feeding conveyor needed, saving equipment investment.
5. Pneumatic clamping structure — firmly locks the magazine during operation, effectively avoiding board misalignment and stacking faults.
6. Special crossover plastic chain + aluminum profile rail — smooth magazine transport, wear-resistant, low noise and long service life.
7. 50 PCS high-capacity storage — reduces frequent magazine change frequency, lowers labor intensity and improves line OEE.
8. Complete electrical configuration (Inovance PLC, Xinje true-color touch screen, Mean Well power, Omron relays) — high stability and low failure rate, easy for overseas customers to maintain.

3. Applications

The HDY-250/330LSB1 L-Type PCB unloader is installed at the end section of complete SMT production lines, mainly used for automatic collection and stacking of finished PCBs into magazines. Typical applications:

• At the end of SMT lines after reflow oven and AOI inspection
• At offline inspection and rework stations requiring PCB batch collection
• In front of PCB storage and transportation systems using standard magazines It is suitable for PCBA manufacturing of consumer electronics, automotive electronics, communication boards, LED lighting, medical electronics and industrial control products.
