EMI Motion-on-EOAT Case Study

EMI end of arm tooling in motion

This custom End of Arm Tooling is packed with new and industry-standard components, complemented by custom laser-cut plate, extruded aluminum profile and 3D printed nests for a hybrid approach to a customer Injection Molding Application, implementing various functions and motions within one custom piece of equipment.

The first function of this EOAT is to remove the finished part from the mold with Hithane vacuum cups mounted on Gimatic threaded suspensions. In this scenario, the mold has 2 cavities which are plumbed in tandem, but can also be configured individually for added control of part release and detection.

Attaching the vacuum cups to the laser-cut plate and using durable threaded suspensions reduces EOAT weight while providing added accuracy. This laser-cut plate is attached to a Size 90 Gimatic Quick Changer with an offset plate and stand-off rods that are designed and machined to ensure the EOAT fits within the customer-specified mold opening.

Equipped with Gimatic Expansion grippers and a 3D printed alignment nest, the other half of this EOAT will pick the inserts from an external fixture using a small vacuum cup for insert detection instead of a photo eye or fiber optic sensor.

The inserts are picked from the front of the EOAT with the Gimatic ZL Slides in their extended position.

The ZL Slides are directly mounted to individual Gimatic R32, 2-position rotary actuators which move the inserts 180°, to the back of the EOAT and the inserts are ready to be placed into the mold.

Once the EOAT is inside the mold and ready to present the inserts to the opposite (stationary) side, the ZL slides will extend 100mm to reach beyond the width of the End of Arm, including the robot arm. Once the inserts are placed into the mold, the EOAT can move on to release the finished parts and to pick up a new set of inserts for the next shot.

Such design can only be achieved using a hybrid approach that includes a combination of stock EOAT components, custom fabricated laser-cut plate and 3D printed alignment nests. The implementation of a Gimatic QC90 Quick Changer enables 2 vacuum circuits, and 4 compressed air circuits to be connected swiftly upon tool installation using a single lever.

EMI EOAT Engineers worked closely with the end user of this End of Arm Tooling during the design process and continue to support the equipment as their production needs evolve.

Zl Low-Profile Pneumatic Slides for EOAT

ZL Low-Profile Pneumatic Slides for EOAT

ZL pneumatic slides have a two bore sizes and two stroke options. Its low profile, light-weight design makes it perfect for EOAT. ZL slides include integrated shock absorbers and have an adjustable stroke. Optional mounting accessories enable clamp mounting.




Gimatic MFD MFU Expansion Grippers

Gimatic MFD MFU Expansion Grippers

Gimatic Expansion Grippers rely on compressing an elastic expander rather than inflating a bladder. They have better durability and up-time because leaks and blow outs are eliminated. Available in a large variety of grip diameters from 8 to 85mm. Optional nose cones, sensors and mounting brackets are available.




Gimatic R Two-Position Swivelling Rotary

Gimatic R Two-Position Swivelling Rotary

The Gimatic R Swivelling Rotary is available in two or three position. The rotary includes shock absorbers and ball bearings. Air feeding is possible directly from the fixing plate.
