The HDY-460 Single-Lane Buffer Machine is a mid-line buffer device designed specifically for SMT production lines. It is primarily used between AOI (Automated Optical Inspection) and SPI (Solder Paste Inspection) processes for intelligent buffering management of NG (defective) and OK (good) PCBs.

Equipment Introduction:
The HDY-460 Single-Lane Buffer Machine is a mid-line buffer device designed specifically for SMT production lines. It is primarily used between AOI (Automated Optical Inspection) and SPI (Solder Paste Inspection) processes for intelligent buffering management of NG (defective) and OK (good) PCBs.
The machine is controlled by a Panasonic PLC system, paired with a Huichuan servo motor and precision ball screw for smooth magazine lifting and accurate positioning. It features a 7-inch Weinview touch screen for intuitive operation. The unit supports pass-through mode, FIFO (First-In-First-Out) buffering, and independent NG board discharge, effectively improving line flexibility and efficiency.
Product advantages over competitors
| Feature | HDY-460 | Common Competitor Models |
| Drive System | Huichuan servo motor + precision ball screw, smooth lifting & precise positioning | Some use stepper motors + chain drives, less stable and accurate |
| Control System | Panasonic PLC + 7" Weinview touch screen, internationally recognized brand | Some use low-end domestic PLC or smaller screens, limited expandability |
| Width Adjustment | Automatic stepper motor adjustment, no manual intervention needed | Some require manual width change, longer changeover time |
| Guide Rods | 2 guide rods on each side for better magazine stability | Some have insufficient or no guide rods, prone to vibration and jams |
| Belt Design | Multi-layer O-ring belt + dual-stage shuttle at entrance, smooth board transfer | Single-layer or basic belts, prone to wear and board jams |
| Storage Flexibility | Independent count & time settings for OK and NG boards | Some support only fixed counts, not adjustable |
| NG Signal Logic | Multiple NG signal selection modes, compatible with various AOI/SPI outputs | Some support only single logic, poor compatibility |
| Electrical Components | Mean Well power supply + Omron relays, guaranteed quality | Some use generic components, higher failure rate |
| EHS Compliance | Fully compliant with EHS requirements | Some do not clearly specify compliance |
产品应用
1.Post-AOI Buffering — After AOI inspection, OK boards proceed to next process; NG boards are temporarily stored for manual review or rework
2.Post-SPI Buffering — Similarly after SPI, isolate NG boards to prevent defects from entering the pick-and-place process
3.Line Balancing — When upstream and downstream speeds differ, the buffer absorbs throughput fluctuations and reduces downtime
4.Offline Repair — NG boards are collected centrally without disrupting main line production
Typical Line Layout:
Printer → SPI → HDY-460 Buffer → Pick & Place → Reflow Oven → AOI → HDY-460 Buffer → Unloader

FAQ
Q1: What is the maximum PCB size supported by HDY-460?
A: Max. PCB length 500mm, width 50-460mm.
Q2: What is the maximum storage capacity?
A: Up to 20 boards.
Q3: How to set OK and NG board storage parameters?
A: Via the 7-inch touch screen, you can independently set OK board count/time and NG board count/time. Simple and intuitive.
Q4: Does it support pass-through mode?
A: Yes. When buffering is not needed, select pass-through mode so PCBs pass directly without entering the magazine.
Q5: How does the NG signal interface with AOI/SPI?
A: The machine offers multiple NG signal selection modes, allowing flexible configuration based on AOI/SPI output signal types. Highly compatible.
Q6: Does the machine support FIFO (First-In-First-Out)?
A: Yes. The FIFO function ensures PCBs enter and exit in order, meeting process traceability requirements.
