振动盘或振动托盘

A vibrating tray or pan is a precisely engineered component within vibration mechanisms that utilizes controlled oscillatory motion to transport, separate, align, or feed components along a defined path. It typically consists of a rigid, shallow container or track mounted on a base that is excited by an electromagnetic or mechanical vibrator. The vibration induces a micro-throwing motion, causing parts to hop forward in a specific direction determined by the tray's geometry and vibration parameters. This component is critical for automating high-speed, precise handling in assembly, packaging, and sorting systems.

The working principle is based on controlled directional vibration. An electromagnetic coil or mechanical eccentric mass generates oscillatory forces. These forces are transmitted to the tray, which is often mounted on inclined leaf springs or a flexible suspension. The vibration causes the tray to move in a slight elliptical or linear path. Parts on the tray experience a series of small hops or slides due to friction reduction and inertia, propelling them in the desired direction (typically uphill due to the tray's angle). The frequency, amplitude, and angle of vibration are precisely tuned to control the speed and orientation of part movement.
