Dual-Track Cooling Buffer Conveyor For SMT Line

The Dual-Track Cooling Buffer Conveyor is a high-performance automated solution designed for modern SMT (Surface Mount Technology) assembly lines. Engineered with a robust sheet metal frame and a dedicated multi-layer aluminum alloy magazine cart, this machine efficiently manages PCB flow between processes. It features a servo motor-driven step elevator for precise magazine handling and a stepper motor conveyor system. With an integrated cooling fan system and a Panasonic PLC controller, it ensures stable operation, preventing thermal deformation of PCBs and ensuring seamless production continuity. The intuitive touch screen interface allows for easy parameter setting and real-time monitoring.

Compared to conventional buffer conveyors on the market, our model offers distinct advantages:

• Advanced Cooling System: Equipped with dedicated cooling fans, it effectively dissipates heat from freshly processed PCBs, protecting sensitive components better than standard models.

• High Precision & Stability: Utilizes precision ball screws for smooth vertical movement and 4MM flat belt transmission for stable horizontal conveying, reducing vibration and jamming risks.

• Smart Control: Panasonic PLC with automatic alarm function ensures high reliability. The FIFO (First-In, First-Out) buffer storage logic prevents PCB congestion and misalignment.

• Flexible Configuration: Supports dual-track operation and adjustable track pitch (25mm / 50mm), making it adaptable to various production line layouts.

• Durable Construction: Built with high-quality materials including a饭金 (Sheet Metal) frame and Omron relays, ensuring a long service life even in 24/7 manufacturing environments.

This buffer conveyor is an essential component for:

• SMT Production Lines: Used for temporary storage and cooling of PCBs between reflow ovens, wave soldering machines, or inspection stations.

• PCB Assembly: Ideal for buffering PCBs during high-speed mounting processes to balance line speed.

• Electronic Manufacturing Services (EMS): Suitable for factories requiring high throughput and reliable material handling.

• Automated Factories: Integrates seamlessly with pick-and-place machines and other automation equipment to create a smart production line.

Q1: What is the maximum number of PCBs this buffer can store?

A: The machine has a maximum storage capacity of 20 PCBs per magazine, utilizing an advanced FIFO (First-In, First-Out) system to ensure orderly output.

Q2: Is the conveyor compatible with large PCB sizes?

A: Yes, it supports PCBs with a maximum length of 480mm and a width range of 50mm to 260mm.

Q3: How does the cooling system work?

A: The unit is equipped with built-in cooling fans that actively reduce the temperature of PCBs as they pass through the buffer zone, preventing warping or solder paste cracking.

Q4: What type of control system is used?

A: It utilizes a Panasonic PLC with an automatic alarm function, paired with an intuitive touch screen for easy operation and maintenance.

Q5: What are the power requirements?

A: The machine operates on standard 220V 50Hz power supply. It includes a complete electrical box with Omron relays for safety.

Q6: Can the conveyor height be adjusted?

A: The standard PCB transfer height is 900 ± 30mm, which is adjustable to fit most production line heights.

Q7: Does it support left-to-right or right-to-left operation?

A: The standard direction is Left to Right, but we can customize the direction based on your specific line layout.

Q8: What materials are used for the frame and belts?

A: The frame is made of high-strength Sheet Metal, and the conveyor uses durable 4MM flat belt transmission with a track pitch selectable at 25mm or 50mm.
