Servo-electric gripping module with IO-Link

With its IEG series Weiss Robotics offers a highly compact and reliable servo electric gripper with integrated controller that can be directly controlled via IO-Link. The IEG is the clever choice for a reliable handling of different parts with similar geometry. The grippers of the new IEG ESD series are ideal for safe handling of electronic components and assemblies.

Now New! Safe handling of electronic assemblies with the new grippers of the IEG ESD series

The new grip­pers of the IEG ESD series are now avail­ab­le for hand­ling sen­si­ti­ve elec­tro­nic com­pon­ents and assem­blies for indus­try 4.0. The com­ple­te­ly con­duc­tive con­struc­tion of the IEG ESD grip­ping modu­les allows safe and ESD-com­pli­ant hand­ling of elec­tro­nic com­pon­ents and assem­blies. This is par­ti­cu­lar­ly important in the field of THT pla­ce­ment, the sing­ling and pal­le­ti­zing of assem­blies or the gene­ral hand­ling in the SMD pro­duc­tion pro­cess and in auto­ma­ted end-of-line tes­ters.



The clever way to grip

The grip­ping modu­les of the IEG series have an inte­gra­ted grip­ping con­trol using a hybrid force con­trol­ler to gua­ran­tee a high per­for­mance grip­ping pro­cess even in dif­fi­cult app­li­ca­ti­ons. Exter­nal posi­ti­on sen­sors and manu­al adjus­ta­ble limit swit­ches are no lon­ger requi­red as the IEG offers an inte­gra­ted high reso­lu­ti­on posi­ti­on sen­sor. It pro­vi­des vir­tu­al limit swit­ches that can be para­me­te­ri­zed easi­ly over IO-Link. As no exter­nal sen­sors are nee­ded any­mo­re, the inter­fe­ring con­tours are mini­mi­zed and the grip­ping pro­cess beco­mes much more reli­able.

Model based Force Control

High performance force control

The inte­gra­ted force con­trol even allows a reli­able grip­ping of britt­le, fra­gi­le and fle­xi­ble parts. A modern model based approach is used to deter­mi­ne the actu­al grip­ping force from the device para­me­ters. The IEG grip­per uses this data for a clo­sed loop force con­trol to ensu­re high­ly dyna­mic and smooth move­ments even with low grip­ping forces. Up to 4 dif­fe­rent grips can be con­fi­gu­red insi­de the grip­per to opti­mal­ly fit the work­pie­ces.



Take full control of your handling process

Thanks to its inte­gra­ted IO-Link inter­face, the IEG series con­nec­ts seam­less­ly to fieldbus envi­ron­ments and PLCs of various ven­dors. This sim­pli­fies con­trol, con­fi­gu­ra­ti­on and dia­gno­sis of the grip­per and gives you maxi­mum con­trol over your manu­fac­tu­ring pro­cess.

Predictive Maintenance

Always have an eye on your machine

At any time the IEG pro­vi­des you cha­rac­te­ris­tic para­me­ters of the grip­ping pro­cess over IO-Link. This enab­les you to que­ry e.g. the actu­al part width as well as the remai­ning grip­ping cycles to the next inspec­tion to sche­du­le the main­ten­an­ce inter­vals well in advan­ce. Always keep your pro­duc­tion in opti­mal con­di­ti­on with inte­gra­ted grip­ping modu­les by Weiss Robo­tics.

Superior quality for highest demands

The robust and smooth run­ning line­ar gui­des allow a pre­ci­se and sen­si­ti­ve grip­ping over the com­ple­te stro­ke. As ano­t­her advan­ta­ge the grip­ping force is near­ly inde­pen­dent of the fin­ger length. The main­ten­an­ce-free brush­less DC motor pro­vi­des a high agi­li­ty and gua­ran­tees a long life­time.
