The switchable magnet AR series offered by PES perfectly meets the above-mentioned expectations. They combine power and compactness for full structured bin picking capabilities.

Indeed, the robot shall slip into the parts to touch the magnet working surface that are hard to access but EOAT size is also critical for access in bin corners at different depths.

To achieve that, a rotating blade is used. It is made up of an electric resistance that heats the sealing blade and the temperature is monitored by a thermocouple temperature sensor embedded in the blade. A slip ring is then used in order to feed the electrical resistance and retrieve thermocouple signals between the rotating blade and the computer side.

Slip ring are thus required to connect moving components such as light electronics and motors to the computer. They can be installed in different axis depending on the projector design and offer full movement capabilities while inducing low mechanical constraints. Different slip ring designs can be chosen according to projector power and features, from capsule to thru-bore slip ring to transfer light and motor power alongside motor encoders signals or DMX controls.

Rotation movement takes place at nearly every step of the process from bottle conveying to label placing. Sometimes, active components are embedded on a rotating plate and linked to the machine computer. Slip ring can perform this link while offering continuous rotation capabilities. Continuous rotation increase machine performance and reliability while easing the machine design.Slip ring can transfer all signal that can be met in such machines, motor power and control, sensors, field buses, etc.

The common link, regardless of the final application, is the use of a Slip Ring or a Rotary Union. Cable reels usually transmit power and electric signals, data and different kind of fluids; instead, in case of high-frequency signals, high data rate or where a low bit error rate (BER) is required, the proper result is achieved with a fiber optic rotary joint. Our product range can cover nearly all application from power signals to high data rate or optical signals for cables and from pressurized air to hydraulic oil for rotary union.

In this particular case, retrieving the information from the set of moving sensors generally requires the use of a slip ring. PES has a large experience in providing slip ring solutions for test benches for many applications. Our large range of standard and custom products allows us to define the exact component needed for a specific test bench (compact size, a large number of circuits, high rotating speed up to 5000rpm).

Among those new tools, once can find magnet grippers. They consist in a pneumatically or electrically actuated mobile magnet placed above a fixed one in order to activate an outer magnetic field that allows handling of ferrous parts while being extremely compact. Magnetic power is already installed in the product so the need for energy is minimal. And, unlike common preconception, residual magnetism of handled parts stays low.

When using a tool changer with tools that embed such cameras, the major challenge is to transfer the high data rate video signal through the tool changer quick connection.

From standard 100Base-TX Ethernet to GigE Vision application, PES always provides the proper electrical interface to meet the communication standard requirement.

Sometimes we also integrate contact redundancy for increased availability of the video link.
