The Vacuum Pad Holder Only is a specialized component designed to prevent workpiece drop during multi-vacuum pad operations. It ensures stable release of workpieces through a two-step mechanism: first, blow-off air releases the workpiece, and second, an internal pin ejects to confirm complete disengagement. This dual-action system addresses common issues such as adhesion and release failure, especially with small or lightweight parts that are prone to sticking to the vacuum pad.
Constructed from durable rubber materials including nitrile rubber, silicone rubber, fluoro rubber, and conductive silicone rubber, the holder is engineered for both mechanical strength and environmental resilience. The material selection supports consistent performance under varying conditions while maintaining reliable sealing and structural integrity during operation.
The holder features a direct mounting design with an integrated mechanical release function. It connects directly to the vacuum pad system without requiring additional fittings or adapters, enabling seamless integration into existing vacuum setups. The mechanism is activated via air pressure inputs that trigger both blow-off and pin ejection sequences.
The unit operates within a positive pressure range of 30 kPa to 0.5 MPa and a negative pressure range of -100 kPa to -30 kPa. When vacuum pressure drops to -80 kPa or lower, the system delivers a suction flow of 4 L/min. The vacuum release valve activates at an operating pressure of 30 kPa for pin ejection, while suction air is supplied at -30 kPa. This precise pressure control ensures reliable and repeatable workpiece release without over-pressurization or under-suction.
The holder is available in a standard configuration with no vacuum pad attached—its outer diameter is φ1.6 mm. It is designed to be used with compatible vacuum pads of specified I.D., ensuring proper fit and function. No color variants are offered, and the product does not vary by size or model type beyond its direct mounting and mechanical release design.
Installation requires direct mounting onto the vacuum pad surface. The holder’s built-in rod mechanism is designed to be integrated into existing vacuum systems where a mechanical release function is needed. Once mounted, it activates automatically when the specified air pressure conditions are met—blow-off air is supplied at -30 kPa and pin ejection occurs at 30 kPa, ensuring secure workpiece release without unintended blowing away after disengagement.
