1. Equipment definition and basic structure
1.1 Definition
Dual rail shuttle conveyors are material handling equipment used in SMT (surface mount technology) or automated production lines. They realize the fast and smooth transfer of PCBs or workpieces through two independent moving heads.
1.2 Basic structure
- Dual head structure (left-right symmetry or synchronous/asynchronous operation)
- Servo motor or stepper motor drive system
- Transverse guide rail and bracket
- Cylinder or suction cup/gripper pick-and-place device
- Sensor and position detection system
- Control system (PLC/HMI/industrial computer)
2. Working Principle
2.1 Transfer Process
1. After receiving the signal, the left/right machine head moves to the material picking point.
2. Use a vacuum suction cup or clamp to remove the material.
3. Move parallel to the target position;
4. Return to the origin or prepare for the next cycle after placing the material.
2.2 Collaborative Action
The two machine heads can:
- Work synchronously: improve efficiency and shorten cycle time.
- Work alternately: ensure continuous operation of the production line.
3. Core functions and application scenarios
3.1 Functional features
- Dual heads coordinate transfer to improve efficiency
- Precise positioning and alignment functions
- Customizable program control for different process requirements
- Connection with front and rear equipment to achieve automation
3.2 Application scenarios
- PCB transfer in SMT production lines (such as board removal → inspection → patch, etc.)
- Loading and unloading of automated production lines
- Connection between board separators, glue dispensers, and testing equipment
- Transfer scheduling for multiple production lines
4. Equipment Features
- Semi-enclosed design ensures the highest level of safety protection.
- PLC control system, color touch screen operation interface.
- Full data input positioning, easy-to-understand operation.
- The position and direction of the inlet and outlet plate can be freely selected.
- Fast, stable, and accurate displacement positioning.
- Automatic width and narrowness adjustment, displacement is driven by precision screw.
- Compatible SMEMA communication method.
5. Operation, maintenance, and precautions
5.1 Operation
- Confirm that the air pressure and power supply are normal before powering on.
- Clean the suction cup or fixture.
- Set parameters and call programs on the touch screen/button.
- Safe operation specifications to avoid pinching your hands.
5.2 Maintenance
- Regularly lubricate the guide rails and screws.
- Check the sealing and suction of the cylinder.
- Backup and upgrade of the software system.
- Replace wearing parts (such as suction cups and belts).
