Selecting End of Arm Tooling

Mar 8, 2012

End of Arm Tooling is also called an end effector. This part of the robot can be customized for the specific application's needs in order to boost productivity and efficiency.


EOA Tool­ing, also known as the end effec­tor, is the robot tool cen­ter in which the part at the end of a robot­ic arm inter­acts with the envi­ron­ment. End of arm tool­ing devices vary by appli­ca­tions and are an essen­tial com­po­nent of a robot. Select­ing EOA parts can be one of the most dif­fi­cult aspects of automa­tion but can be made eas­i­er when under­stand­ing your end-users needs.

Pow­er Sources

The first step in choos­ing EOA parts is to select a pow­er source. EOATs may run either elec­tri­cal­ly, hydrauli­cal­ly, or pneumatically.

Pneu­mat­ic pow­er sources are pop­u­lar among the pack­ag­ing indus­try because of their weight to pow­er ratio. They are read­i­ly avail­able and are capa­ble of apply­ing pow­er­ful forces at great speeds. They are most effecitve for gen­er­at­ing force and motion simul­ta­ne­ous­ly. Pneu­mat­ic sources do have some draw backs as they can lack con­trol and flexibility.

Hydraulic EOAT pow­er sources pro­duce strong clamp­ing forces and act quick­ly. How­ev­er this pow­er source is expen­sive due to the large com­pres­sors need­ed to run the flu­id in it.

Elec­tron­ic pow­er sources are pop­u­lar for appli­ca­tions requir­ing mod­er­ate force at a high speed. It is also the clean­est pow­er source mak­ing it ide­al for han­dling dust sen­si­tive prod­ucts and offers a greater range of control.

End of Arm Tool­ing Types

After select­ing a pow­er source the next step is to decide what device will be the best end effec­tor for your appli­ca­tion. Some pop­u­lar options include:

Adap­tive Grip­pers- These work well with pack­ag­ing and han­dling con­sumer goods because they can auto­mat­i­cal­ly adjust accord­ing to prod­uct type. They are also ide­al for han­dling parts with holes that can­not eas­i­ly be manip­u­lat­ed by vac­u­um grippers.

Par­al­lel EOATs- These are per­fect for weld­ing appli­ca­tions involv­ing well defined objects, such as boxes.

Vac­u­um EOATs- These are the most pop­u­lar and most cost effec­tive form of EOA tool­ing as they can han­dle most parts and sur­faces. They are ide­al for han­dling prod­ucts that require a light touch. Vac­u­um grips are much strong than they appear while offer­ing flex­i­bil­i­ty as air pres­sure may be adjust­ed to reach your desired force.
