An automatic orientation hopper utilizing directional vibration. Vibration hoppers are commonly used in machine tool loading and unloading devices, and are widely applied in industries such as instrumentation and electronic components. The vibration hopper operates smoothly, suitable for various small workpieces that have undergone partial finishing. The hopper has certain versatility; when used for different workpieces with similar dimensions and weights, only the directional mechanism needs to be replaced (refer to the machine tool loading and unloading device).
