Understanding PCB Turning Machines

The PCB turning machine enables to turn the direction of PCB board in 90 or 180 degree, which can change the horizontal transmission of each PCB to be suitable for L shape or T shape production line. It is important for making a right and smooth PCB board transportation on assembly line.

ElectronicTalk provides standardized PCB turning machine. By using the PCB turning machine, saving the space of a SMT line, which can be applied flexibly.

Equipped with touch-screen control panel, it is easy to be operated. More importantly, as using the step motor, the stable and precise rotation function control is ensured.

Also, applicable width adjustment, it used the imported screw elevator of TBI with higher accuracy and long durability. Besides, the machine size is customized as well as the transmission of PCB board.

PCBs need to be flipped and rotated numerous times during assembly processes like solder paste inspection, component placement, soldering, cleaning, and testing. Manual flipping creates inconsistencies and bottlenecks. PCB turning machines enable fast and reliable turning automation.

PCB turning machines grip PCBs securely and flip them over in a smooth rotational motion. This allows consistent and fast orientation changes needed between assembly processes, without relying on manual labor.

PCB turning machines are also referred to as:

PCB inverters

PCB rotators

PCB flippers

Key benefits over manual turning:

Faster process times improve workflow

Secure handling prevents PCB damage

Precision rotation improves quality

Handling consistency from automation

Simpler integration with assembly lines

Types of PCB Turning Machines

Pneumatic Turning:

Uses air cylinders to provide rotating force. Compact but limited rotation control.

Servo Motor Turning:

Controlled servo motors enable precision 180° or multi-axis turns.

Conveyor-Based Turning:

PCB sandwiched between rotating conveyor belts.

Robotic Turning:

Industrial robots used for controlled PCB rotation.

Key Components of PCB Turning Machines

Leverage automation capabilities for round-the-clock operation.

Perform planned preventative maintenance.

Use machine data insights to identify bottlenecks.

Continuously monitor key performance metrics.

Train employees thoroughly on proper machine operation.

Each percentage gain in utilization results in major productivity payoffs.

Common Challenges and Solutions

PCB jamming:

Check for obstructions or gripper issues. Adjust pressure as needed.

Positioning errors:**

Re-calibrate sensors; inspect component wear; check air supply.

Rotation stalling:

Verify power connections; check servo/pneumatic systems; inspect for mechanical issues.

PCB scratches:

Adjust gripper contact areas; check for burrs or defects.

Excess vibration:

Tighten fasteners; lubricate or replace worn components like bearings.

Control faults:

Restart; upgrade software; replace faulty modules.

Promptly addressing any problems is vital for maximizing machine uptime.

Safety Measures and Precautions

PCB turning machines can pose some safety risks like:

Getting body parts caught in machine

Electrical hazards during maintenance

PCBs or debris falling from height

Safety measures should include:

Enabling emergency stop buttons and interlocks

Implementing proper lockout/tagout procedures

Providing applicable personnel safety training

Ensuring accessible e-stop buttons

Following manufacturer’s safety guidelines

Case Studies

Company A installed servo-driven PCB turning machines to automate flipping before and after wave soldering. This improved the line’s hourly output by 18%.

Company B integrated robotic PCB turning into their automated optical inspection process. This enabled faster inspection while reducing human involvement.

Company C’s PCB rework rate caused by bent pins or misalignments decreased from 3.2% to 1.5% after deploying pneumatic turning machines.
