Execs of pneumatic grippers embrace low value, massive grip pressure vary, skill to function in tight areas and quick response instances. Nonetheless, pneumatic grippers are finest suited to dealing with single half varieties, so they won’t be an excellent match in case your facility produces loads of low quantity/excessive combine objects. This gripper sort additionally gives restricted pressure and place management and requires compressed air to perform.
Hydraulic grippers
Powered by hydraulic fluids, hydraulic grippers present extra gripping energy than their pneumatic counterparts, making them superb for heavy responsibility functions.
The primary benefit of hydraulic grippers is their wonderful gripping energy, however with that energy come a number of disadvantages, together with the added complexity of dealing with oil, a pump, and a reservoir. Consequently, hydraulic grippers are typically greater upkeep than different gripper varieties and they’re additionally unsuitable for many cleanroom and lots of medical functions.
Electrical grippers
Electrical grippers are a preferred alternative for a lot of cobot functions together with machine tending and decide & place. Whereas they do not provide the identical stage of gripping energy as hydraulic grippers, they’re appropriate for functions that require excessive velocity and lightweight/average gripping pressure. Electrical grippers normally are available in two-jaw and three-jaw configurations, with 3 jaw grippers usually being chosen when spherical/cylindrical objects should be dealt with.
For instance, STAMIT, a machine tooling firm primarily based within the Czech Republic, used a 2-finger electric gripper from Robotiq and a UR10 cobot to care for CNC machine tending duties in its excessive combine manufacturing atmosphere (4,000 in a different way tooled objects and 12 million elements complete, every year).
