Custom EOAT for Cobots from EMI

custom EMI EOAT for cobots

EMI EOAT Engineering is available to help develop your next Custom Cobot Application. If you need a single vacuum cup attached to your cobot, or a two-sided EOAT for ultrasonic welding EMI has the support, inventory and experience to provide a solution that is cost effective yet durable and tailored to your application needs.

Below you can see some custom designs that have been developed by EMI from the ground up: Vacuum end effectors using OnRobot’s electric vacuum generators, dual gripper setups for machine tending, two-sided insert-loading EOAT for plastic injection molding, and pick-and-place via vacuum or soft touch grippers.

Contact our EOAT Engineers to discuss your next project; whether you’re getting the first cobot in-house, or if they’re being implemented across your facility.

sawyer with dual cobot eoats and parts

2-Sided Vacuum Eoat With Self-Contained Part Rotation

This custom end-effector uses independent vacuum circuits on opposite sides to grip 2 different parts out of an Injection Molding Machine, for placement into a secondary assembly process. Before placement, self-contained 180° rotary action is required for proper reorientation of a part. Once the secondary assembly is complete, the EOAT removes the final assembly.

Onboard pneumatic valves control air flow to cartridge vacuum generators, and part confirmation is achieved through vacuum monitor switches. All I/O operates through ClickSmart connectors at Sawyer’s wrist.

doosan with dual cobot eoats and parts

Two-Gripper EOAT with Quick Changer

A custom EOAT to handle a singular part using two pneumatically-powered grippers for added security and positional consistency. A V-groove nest assists in guiding the EOAT into position during robot setup and locating the part during pick and place operations. On-gripper inductive sensors provide part confirmation to the robot through electrical connectors on the quick changer, while pneumatic pass-through in the quick changer automatically connects the robot-provided air to operate the grippers.

Custom Cobot Application with QC75

The Gimatic QC-75, a Cobot-specific quick changer, provides a quick disconnect for the EOAT and all of its electrical and pneumatic connections. The QC-75 also provides a confirmation signal that the EOAT is properly mounted and locked onto the Cobot. Mount this quick changer to your Cobot with hole pattern ISO-9409-1-50-4-M6.

Custom EMI Cobot Application

Custom 3D Printed EOAT

Our 3D-printed material provides a durable, yet very lightweight mounting interface for vacuum cups, and suspensions in this multi-cavity Cobot application.

Nine parts with a porous surface are gripped with silicone foam vacuum cups that adhere and provide an adequate holding force in order to transfer the workpieces from a conveyor to their intended application.

Smaller than the Q# 8210 VG10, the VGC10 can fit into tight environments to extend your automation possibilities. And at half the weight of the VG10 but with the same payload, the VGC10 can lift small, odd-shaped, and heavy objects even with a smaller robot arm. The VGC10 features two independently controlled air channels that allow it to act as a dual gripper with pick-up and release in the same action, further increasing efficiency and reducing cycle time. With no compressor or air supply needed, this compact electrical gripper is easy to move, and simple programming makes it quick and easy to redeploy for greater production flexibility.

  • Built-in electric vacuum generator.
  • Weight: 0.814kg / 1.79 lbs
