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.

• 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.

• 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.

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.
