A vacuum channel is a critical component integrated into pad holders or machine bodies, designed to generate and distribute vacuum pressure through a network of precisely machined passages. It enables secure material holding, positioning, and transfer in automated systems by creating negative pressure zones that adhere workpieces to pads or fixtures. These channels are engineered with specific geometries to optimize airflow, minimize pressure loss, and ensure consistent performance in industrial applications.

定义
A vacuum channel is a critical component integrated into pad holders or machine bodies, designed to generate and distribute vacuum pressure through a network of precisely machined passages. It enables secure material holding, positioning, and transfer in automated systems by creating negative pressure zones that adhere workpieces to pads or fixtures. These channels are engineered with specific geometries to optimize airflow, minimize pressure loss, and ensure consistent performance in industrial applications.
工作原理
The vacuum channel operates by connecting to a vacuum source (pump or ejector) that evacuates air from the channel network, creating negative pressure. This pressure differential causes atmospheric pressure to push workpieces against the pad surface, providing secure holding force. The channel's design ensures even pressure distribution across multiple pads and maintains vacuum integrity during operation.
