A complete flexible feeder system is an integrated mechatronic device consisting of the following key functional modules and components:
I. Core Vibration and Handling Module
Vibratory Platform/Feeder Base: Generates micro-amplitude, multi-axis vibration to scatter parts.
Flexible Feeding Tray/Plate: The removable surface placed on the vibratory platform.
Pin Tray: With an array of pins to stabilize parts.
Textured/Coated Tray: Surface with a specific friction coefficient.
Magnetic Tray: For ferromagnetic parts.
Platform Controller: Adjusts vibration frequency, amplitude, and mode.
II. Vision Recognition Module
Industrial Camera: Typically a high-resolution area scan camera.
Industrial Lens: Selected based on field of view and accuracy requirements.
Lighting System: Critical for highlighting part features.
Ring Light, Bar Light, Dome Light, Coaxial Light, etc.
Light Controller: For adjusting intensity and strobe.
Vision Processor: Industrial PC or embedded vision system.
Vision Software: Core algorithm for part recognition, location, and coordinate calculation.
III. Robot Picking Module
Industrial Robot: Typically a 6-axis or SCARA robot.
Robot End-Effector:
Vacuum Cups/Suction Grippers: For flat-surfaced parts.
Pneumatic or Electric Grippers/Jaws: For parts requiring clamping.
Custom Tooling.
Vacuum Generation Unit: Vacuum ejector or pump if suction is used.
Robot Controller.
IV. Control & Electrical Module
Master Controller: Usually a PLC, synchronizing the platform, vision, and robot.
Communication Interface: Facilitates data exchange between PLC, vision, and robot.
Electrical Cabinet: Houses circuit breakers, relays, power supplies, servo drives, etc.
Human-Machine Interface: Touchscreen for parameter setting, monitoring, and manual operation.
V. Auxiliary & Structural Module
Machine Frame: Supports and aligns all components.
Safety Guarding: Protective covers or light curtains.
Loading Mechanism (Optional): Automated device to pour bulk parts onto the tray.
Output/Transfer Guide: Channels for moving picked parts to the next station.
Cabling & Pneumatic Lines: Wires, cables, and air hoses connecting all components.
Summary: A flexible feeder is a sophisticated system integrating vibration, vision, robotics, and control. Its components are configured around the core workflow of “scatter, identify, and pick” to perform intelligent parts feeding.
