Product Introduction – Dual-track Screening Machine / PCB Buffer Conveyor

Model: XY-SX350S

The XY-SX350S is a high-performance Dual Track PCB Screening and Buffer Conveyor, designed to temporarily store (buffer), screen, or pass PCBs during production line pauses or flow balancing. It features two independent transport lanes for dual-lane SMT lines, increasing efficiency and line utilization while preventing bottlenecks.

This model is especially useful between equipment such as SPI, mounters, AOI, and reflow ovens, where timing discrepancies or line balancing are required.

Key Features:

Dual-lane transport system for independent or synchronized operation
Buffer function to store PCBs during downstream stoppages
Screening/inspection zone for temporary holding or operator visual check
SMEMA interface compatible for full line automation
ESD-safe belts and frame, suitable for handling sensitive PCBs
Adjustable rail width for multiple PCB sizes
Supports multiple modes: pass-through, buffer, manual inspection

Technical Specifications:

Application Scenarios:

Buffer between SPI and mounter or mounter and AOI
Temporary PCB screening area for quality check
Balancing dual-lane production lines
Pass-through mode when buffering is not required
Compatible with LED, automotive, and consumer electronics SMT lines

Optional Features:

Signal tower light (3-color)
Barcode scanner mount
MES system interface
Manual inspection station (magnifier lamp, operator pad)
Safety light curtain or acrylic shield
Motorized rail width adjustment

FAQ Guide – Dual Track PCB Buffer Conveyor (Model XY-SX350S)

1. What is the main function of the XY-SX350S?

The XY-SX350S is a dual-track screening and buffer conveyor, used to temporarily store, inspect, or transfer PCBs between SMT machines. It helps balance the flow between equipment, prevent line stoppages, and allow for manual inspection if needed.

2. Where is it typically used in a production line?

It is commonly placed between:

SPI and mounter
Mounter and AOI
AOI and reflow oven
Other bottleneck points in a dual-lane SMT production line

3. What is the maximum PCB size supported?

Each lane supports PCB sizes from 50 × 50 mm up to 350 × 250 mm. Custom sizes are also available upon request.

4. Can it operate in both pass-through and buffer mode?

Yes. It supports multiple modes:

Pass-through mode (normal transport)
Buffer mode (temporary holding during line pauses)
Screening/inspection mode (manual check zone)

5. Does it support SMEMA communication?

Yes, it has dual SMEMA interfaces (one per lane) for communication with upstream and downstream SMT equipment.

6. Is the rail width adjustable?

Yes, the conveyor has a manual or motorized rail width adjustment system, allowing it to handle different board widths.

7. What type of belts does it use?

It uses ESD-safe timing belts, 6 mm wide, designed to protect sensitive PCBs from static electricity during transport.

8. What is the standard height of the machine?

The transport height is 900 ± 20 mm, which is standard for SMT lines and can be adjusted with the machine feet.

9. Is air supply required?

Only if the machine includes pneumatic components like a stopper for manual inspection. In that case, an air pressure of 4–6 kg/cm² is required.
