1. Equipment Introduction
The HDY-390HB SMT PCB Direction Changer is a specialized automated device designed to change the orientation of PCBs by 90 degrees on SMT production lines. It converts PCB travel direction from narrow-side leading to wide-side leading, or vice versa, optimizing board flow for different process stages such as printing, placement, reflow, and inspection.
With dimensions of L600 * W640 * H1200mm, the machine handles PCBs up to L460mm * W390mm with thickness ranging from 0.5mm to 3mm. The conveyor uses a 4mm flat belt driven by a stepping motor, and the 90-degree rotation is performed by a pneumatic buffer mechanism for smooth, precise directional change.
The system is controlled by a touch screen + PLC with automatic width adjustment via stepping motor. It supports SMEMA communication protocol for seamless integration with upstream and downstream equipment. Key components include TBI ball screws, Leadshine stepper motors/drivers, AirTAC cylinders and solenoid valves, Omron limit sensors, and Mingwei switching power supply, ensuring high reliability and precision.
2. Competitive Advantages vs. Peers
-
True Direction Change Function: Unlike simple flip machines, the HDY-390HB performs narrow-to-wide or wide-to-narrow conversion, solving real PCB flow problems in SMT lines.
-
Fast Cycle Time: Achieves ≤30 seconds per board, faster than typical 35–45 second converters, improving overall line throughput.
-
Automatic Width Adjustment: Stepping motor auto-adjusts to different PCB widths, eliminating manual setup and reducing changeover time by over 80%.
-
Three Operating Modes: Supports narrow-to-wide, wide-to-narrow, and straight-through pass modes, offering maximum flexibility for different line layouts.
-
Premium Components: Uses TBI ball screws, Leadshine drivers, AirTAC pneumatics, and Omron sensors — far superior to generic parts found in budget models, ensuring 50,000+ hours of stable operation.
-
ESD Safe Design: All contact surfaces and moving parts are ESD-protected, preventing electrostatic damage to sensitive electronic components.
3. Product Applications
-
SMT Production Lines: Changes PCB orientation between solder paste printing, pick-and-place, reflow soldering, and AOI inspection stations.
-
Mixed-Model Assembly: Handles different PCB sizes and orientations without manual adjustment, ideal for high-mix low-volume production.
-
Automotive Electronics: Ensures proper board orientation for automotive-grade PCB assembly processes.
-
Medical Device Manufacturing: Provides reliable, repeatable direction change for sensitive medical electronics.
-
EMS Contract Manufacturing: Reduces labor cost and human error in high-volume PCB handling operations.
4. FAQ
Q1: What is the difference between this machine and a PCB flipper?
A: A flipper turns the PCB over (top to bottom). The HDY-390HB changes the travel direction by 90 degrees — converting narrow-side leading to wide-side leading, or vice versa — without flipping the board.
Q2: What is the maximum PCB size this machine can handle?
A: It supports PCBs up to L460mm * W390mm with thickness from 0.5mm to 3mm.
Q3: How fast is the direction change cycle?
A: The cycle time is ≤30 seconds per board.
Q4: Does it support automatic width adjustment?
A: Yes, it features automatic width adjustment via stepping motor, adapting to different PCB sizes automatically.
Q5: What operating modes are available?
A: Three modes: narrow-to-wide, wide-to-narrow, and straight-through pass.
Q6: What control system does it use?
A: It uses a touch screen + PLC (Huizhang) for intuitive operation and parameter setting.
Q7: Can it communicate with other SMT equipment?
A: Yes, it supports SMEMA communication protocol for seamless line integration.
Q8: What are the power and air requirements?
A: Power: 220V 50Hz. Air pressure: 0.4–0.6MPa.
