Suction cup kit for Dobot Magician E6

Quick Answer: The Suction cup kit for Dobot Magician E6 is a vacuum end tool that lets the Magician E6 cobot lift parts by sealing a flexible cup against a flat surface and lowering the air pressure inside it. It is used for quick pick-and-place of smooth, flat items such as tiles, cards and boxes, and for teaching how air pressure holds a part.

Atmospheric Pressure at Work

A suction cup does not pull a part; the surrounding air pushes it. When the vacuum source lowers the pressure inside the sealed cup, the higher atmospheric pressure outside presses the part against the cup. The holding force is roughly the pressure difference multiplied by the area inside the seal, so a larger cup or a stronger vacuum holds more. That calculation turns the suction cup kit for Dobot Magician E6 into a physics lesson as well as a robotics one.

The seal is everything. A flat, smooth, non-porous top such as plastic, glass, painted metal or coated card seals well. Fabric, foam, rough wood and parts with holes let air leak in, and the part drops. Students soon learn to choose pick points on the flattest area and to lower the cup gently so the lip is evenly compressed before lifting.

How the vacuum is generated, whether a pump is part of the kit, and the cup sizes supplied should be confirmed before ordering.

Specifications

Care & Handling

• Inspect the suction cup lip before each session; nicks, dust or a hardened lip break the seal.
• Clean cups with water and a little mild detergent, rinse and air-dry; avoid solvents and oils that swell or harden the rubber.
• Check that the tubing is not kinked or cracked, since a small leak reduces the holding force on every pick.
• Keep hair and small loose items away from the cup while the vacuum is on.

Applications

• Rapid pick-and-place and stacking of flat blocks and tiles
• Packing flat items into trays in production-line simulations
• Physics investigations relating cup area and vacuum to the heaviest part that can be lifted
• Comparing suction with the electric and electromagnetic grippers on the same set of parts

Frequently Asked Questions

Why won’t the suction cup pick up some objects?

The cup cannot seal. Porous materials such as foam or fabric, rough or textured surfaces, curved parts smaller than the cup, and parts with holes under the lip all let air in. Choose a flatter pick point or use a gripper instead.

How much can a suction cup lift?

In principle, the pressure difference times the sealed area. In practice leaks, cup flexing and fast movements reduce this, so allow a large safety margin and test with the actual parts at the speeds you plan to use.

Why does the part fall off during fast moves?

Acceleration adds to the force on the seal and can peel the lip. Slow the move, place the cup near the part’s centre of mass, or use a larger cup so the holding force comfortably exceeds the load.

How should the cup be lowered onto a part?

Lower it straight down until the lip is compressed evenly, switch on the vacuum, pause briefly, then lift. Approaching at an angle or lifting too soon leaves a partial seal.

Does the kit include its own vacuum pump?

Suction kits are supplied in different forms, so confirm the vacuum source when you enquire. Without a working vacuum source the cup cannot hold anything, so it matters when planning lessons.

How do I clean and store the suction cups?

Wash with water and mild detergent, rinse, dry in the air and store cups without anything pressing on the lip. Replace any cup whose lip has cracked, hardened or lost its shape.
