Dual track PCB Conveyor​
Our company has been in operation for 11 years and will definitely be your best choice with guaranteed quality and fast delivery





Product Introduction – Dual Track PCB Conveyor
The Dual Track PCB Conveyor is a specialized SMT inline transport device designed to simultaneously transfer PCBs on two independent lanes, allowing for high-efficiency operation in dual-lane or high-mix SMT production lines. It is typically installed between machines such as screen printers, SPI, mounters, AOI, and ovens, and is essential for balancing, buffering, or linking dual-lane SMT equipment.
With ESD-safe construction and SMEMA compatibility, this conveyor provides smooth, reliable board transfer while saving factory space and reducing line downtime.

Key Features:
Two fully independent PCB transport tracks
Supports dual-lane synchronous or asynchronous production
Compatible with SMEMA communication for each lane
Adjustable rail width (manual or motorized)
ESD-safe construction (anti-static belts and frame)
Optional buffering, bypass, or accumulation mode
Compact footprint with height-adjustable feet

Technical Specifications:

Applications:
PCB transfer between SMT machines (printer, SPI, mounter, AOI)
Dual-lane production balancing
Transport of OK boards from dual-track AOI or test stations
Ideal for LED, automotive, and consumer electronics assembly lines

Optional Features:
Signal tower light (R/Y/G with buzzer)
NG/OK separation logic
Motorized width adjustment
MES connection module
Barcode scanner mount
Safety covers or curtains

FAQ Guide – Dual Track PCB Conveyor

1. What is a Dual Track PCB Conveyor used for?
It is used to transport PCBs on two independent lanes simultaneously in high-speed SMT production lines. Common applications include connecting dual-lane machines, balancing line flow, or handling NG/OK boards after inspection.

2. What are the advantages of dual track over single track?
Doubles throughput by handling two lanes at once
Allows parallel production of two board types or processes
Saves space compared to two single-lane conveyors
Ideal for AOI, SPI, printer-to-mounter, or oven output connections

3. Is the conveyor width adjustable?
Yes. Most dual track conveyors have manually or motor-adjustable rail widths to accommodate different PCB sizes. Each lane may have its own adjustment or shared mechanism depending on the design.

4. What PCB sizes are supported?
Typically supports 50 × 50 mm to 460 × 250 mm per track
Custom widths are available on request

5. What is the standard conveyor height?
Standard height is 900 ± 20 mm, compatible with SMT line equipment
Adjustable support feet are included to fine-tune the height

6. What control methods are available?
Basic version: Push-button panel
Advanced version: Touchscreen HMI + PLC
Control options include start/stop, width adjustment, speed control, and alarm reset

7. Is it SMEMA compatible?
Yes. The dual track conveyor includes two sets of SMEMA connectors (one per lane) for easy inline integration with upstream and downstream machines.

8. What is the belt type used?
Uses anti-static (ESD-safe) timing belts, typically 6–8 mm wide
Belts ensure gentle, stable PCB movement without electrostatic damage

9. Does it require air supply?
Only if equipped with pneumatic stoppers or gates
If included, the required air pressure is typically 4–6 kg/cm²

10. What are common optional features?
Signal tower light (R/Y/G with buzzer)
Barcode scanner mount
Motorized width adjustment
MES system integration
NG/OK diverter
Safety light curtain or acrylic covers

11. What are the maintenance requirements?
Clean belts and sensors weekly
Lubricate bearings, pulleys, or guide rails monthly
Inspect belts for wear and replace if needed
Check motor and PLC connections quarterly

12. How long is the delivery time?
Standard models: 3–5 working days
Customized sizes or features: 7–10 working days
