High temperature pick and place

Achaniotis

Hi all,

I am interested in purchasing a Robotiq gripper for a pick and place application using a FANUC robot. The temperature factor is quite important as the application requires the gripper to be resistant to temperatures around 480°C. Can someone come up with a suggestion (a gripper attachment possibly)?

Thank you

@Chris_Tur Can your glove be a good fit for this application?

@Achaniotis would that be constant temperature or would it be the part/peak temperature ? Our Gripper cannot work at a constant temperature of 480°C, if the part is at 480 we can probably work something with the fingers to have it running fine. Otherwise there are other solutions on the market but an electric gripper like ours could not handle ambiant conditions like this.

Roboworld has developed a gripper cover for the Robotiq 2F85 product.  A brief video is attached.

We are limited by the relatively low inertia of the fingers when specifying higher-temp fabrics.  Higher-rated materials (>500C) are simply too stiff or too heavy to use on this particular gripper model. 

The material shown in the video (Isotherm) is rated to 260C (and only intermittently to 370C).  This could possibly be increased with the use of internal cooling beneath the gripper cover, though I have no data to suggest it could make it to 480C.

If you would like to consider a protective thermal cover for your application--please visit https://www.roboworld.com, and request a quotation.  One of our representatives would be happy to assist.  Please be certain to cite the specific gripper model you are considering.

480°C will be the part temperature after it comes out of a pre-heating furnace. I am assuming that the part will not spend more than a few seconds in contact with the gripper. The temperature of the working environment will be at normal industrial levels.

@Etienne_Samson The application would require the encompassing grip, so this is to consider when thinking about the temperature.

@Catherine_Bernier @Achaniotis I would try to avoid the encompassing grip with a part at this temperature, too much heat transfer to the Gripper main casing. The casing is what need to be kept at lower temperature, it got the mechanical transmission grease that need to stay cooler and the embedded controller electronics that also need to be protected. Isn't it possible to design some custom fingertip to get that part without being in contact with the casing ? That would be the simplest solution. @Chris_Tur glove should also be considered.
