Working Principle

The ZP3-Y04UMGNK10-U4 operates on the principle of vacuum suction. When the pad contacts the workpiece surface, air is evacuated from inside the pad by a vacuum generator or vacuum pump, creating a vacuum (negative pressure). This causes the internal pressure to be lower than the external atmospheric pressure, and atmospheric pressure presses the workpiece firmly against the pad, achieving the gripping function. To release the workpiece, air is introduced into the pad to equalize the internal and external pressure, allowing the pad to detach automatically.

Workflow:

1. Pad contacts the workpiece surface.
2. Vacuum generator activates, evacuating air from inside the pad.
3. Vacuum forms inside the pad, generating adsorption force.
4. Atmospheric pressure presses the workpiece against the pad.
5. Workpiece is moved to the designated position.
6. Air is supplied to the pad, releasing the workpiece.

Typical Application Scenarios

1. Industrial Automation Production Lines In automated production lines for automotive manufacturing, electronic device production, etc., used for gripping and handling workpieces like glass, metal sheets, and plastic parts. It enables automatic loading, unloading, and positioning of workpieces, improving production efficiency and product quality.
2. Packaging Machinery For controlling actions like material conveying, sorting, and palletizing in packaging machines. Vacuum pads enable the gripping and placement of packaging materials of various shapes and materials, ensuring precision and stability in the production process.
3. Robotics Serves as an end effector for robots, working in conjunction with robotic arms to grip, position, and place workpieces. It enhances the motion accuracy and efficiency of robots. Its fast response characteristic is particularly suitable for high-speed handling applications.
4. Precision Manufacturing Equipment In equipment for semiconductor manufacturing, precision machining, etc., used for gripping and handling precision workpieces. It ensures stability and repeatability in the machining process, improving product quality.

Installation and Usage Precautions

1. Installation Requirements The vacuum pad should be installed perpendicular to the workpiece surface for stable operation. Before installation, check that the air supply pressure meets the 0.1~0.7 MPa requirement and ensure the air supply is clean. Pay attention to the contact angle between the pad and the workpiece surface during installation to ensure a good seal.
2. Operating Environment The operating temperature range is -10 ~ 60°C. Avoid use in extremely high or low-temperature environments. Maintain relative humidity within an appropriate range to prevent moisture from affecting equipment lifespan. The working medium should be filtered through a 40μm or larger filter element before use.
3. Piping Connection Before piping, thoroughly blow or clean out cutting powder, cutting oil, dust, etc., from inside the pipes. When using threaded connections for piping and fittings, prevent chips from the threaded parts and fragments of sealing tape from entering the piping interior. When using sealing tape, leave 1.5-2 pitch lengths at the thread end without tape.
4. Workpiece Surface Requirements The workpiece surface should be flat, smooth, and free of oil to ensure good contact and effective sealing with the pad. For rough or porous surfaces, choose pads with ribs or bellows types to improve suction effectiveness.
5. Regular Maintenance Regularly inspect the pad’s connecting piping and seals to ensure no leakage. Periodically clean the pad surface to maintain cleanliness. Regularly check the pad’s adsorption performance to ensure long-term stable operation. Before reuse after prolonged shutdown, performing a venting/flushing operation is recommended.
6. Safe Operation Ensure the equipment is properly grounded before operation to prevent electric shock risk. Avoid contact with moving parts during operation to prevent injury. In case of equipment failure, stop immediately for repair by qualified personnel. Before installation, depressurize to prevent high-pressure medium ejection causing injury. Strictly prohibit use beyond the product’s rated pressure, temperature, and medium range.
