Shenzhen Hansome Technology Unveils HS-RC390 Series NG Reject Conveyor to Upgrade PCB Automated Production Lines

Shenzhen Hansome Technology Co.,Ltd, a professional manufacturer of SMT peripheral automation equipment, officially launches its brand-new HS-RC390 series NG reject conveyor, a core sorting device tailored for printed circuit board (PCB) manufacturing workflows paired with AOI, SPI and other mainstream PCB testing machines. This innovative conveyor integrates automatic good and defective board separation, offline visual inspection and bypass conveying functions, resolving the long-standing bottleneck of interrupted production when inspecting NG PCBs in traditional SMT assembly lines.

Multi-Mode Flexible Operation Meets Diverse Production Demands

The HS-RC390 series supports three core working modes: reject mode, inspection mode and by-pass mode. In reject mode, unqualified NG PCBs are automatically diverted and temporarily stored without blocking the normal transmission of qualified boards. Operators can conduct detailed visual inspection on stored defective boards under inspection mode, while the good PCB flow runs continuously without halt. The by-pass mode allows all PCBs to pass through directly for scenarios that do not require sorting, enabling manufacturers to switch working states freely according to daily production schedules.

Modular & Robust Mechanical Design for Long-Term Stable Operation

Adopting full modular design, the whole machine supports split assembly and quick component replacement, greatly cutting maintenance downtime and simplifying equipment transportation and on-site installation. Its heavy-duty solid frame structure strengthens overall mechanical stability to eliminate jitter during high-speed PCB conveying, avoiding board scratching or misalignment issues in mass production.

The side guide of the conveyor adopts laser-carved stainless steel material, delivering outstanding surface flatness, wear resistance and corrosion resistance compared with ordinary metal guides. The laser carving process ensures precise dimensional tolerance for long-term repeated width adjustment, extending service life and maintaining consistent conveying accuracy over years of heavy use.

For operator comfort, the equipment is equipped with an ergonomic arm rest. Staff who need long-duration visual inspection of defective PCBs can rest their arms comfortably to reduce fatigue and improve inspection accuracy. The width adjustment system adopts a lead screw driving structure, achieving smooth, parallel rail expansion and contraction without offset, adapting to PCBs of different widths stably.

Customizable & Adjustable Transmission Performance

Two standard models are available in the HS-RC390 lineup: HS-RC390 and extended HS-RC390L. Both models support PCB widths ranging from 50mm to 390mm, covering most mainstream PCB sizes for consumer electronics, automotive electronics and industrial control boards. Customers can select standard rail lengths of 600mm (HS-RC390) or 1000mm (HS-RC390L), while customized machine lengths are also acceptable per special production line layout requirements.

Transportation direction is optional for left-to-right or right-to-right conveying to match existing line layout of different factories. The conveying speed supports stepless variable speed control within 0.5 to 20 meters per minute; users can also lock a customized fixed speed to match the beat of upstream AOI/SPI testing equipment. The standard temporary storage capacity for NG PCBs is 5 pieces, and customized storage quantity is available for factories with high defective board output.

Standardized Power, Air & SMEMA Communication Compatibility

In terms of power configuration, the conveyor adopts universal single-phase AC 100-230V wide voltage input, adapting to power supply standards of global electronics manufacturing plants. The maximum power consumption of the whole unit is only 100VA, which effectively reduces long-term factory energy costs. For pneumatic driving parts, the required working air pressure ranges from 4 to 6 bar, with a maximum air consumption of 10 liters per minute, matching general factory central air supply systems without additional air compressor transformation.

A core highlight of this equipment is full SMEMA communication compatibility. It can realize seamless signal interconnection with upstream and downstream SMT equipment including screen printers, SPI, AOI and reflow ovens, automatically transmitting PCB passing, rejecting and fault signals to realize fully unmanned linkage of the whole production line, eliminating manual signal docking errors.
