Developing a pick and place application involves careful consideration of various components, including the selection of the robot and gripper. This guide explores best practices, key considerations, and technical details necessary for successful deployment of a pick-and-place application.
Gripper Selection for Pick and Place Applications
OnRobot, a leading provider of end of arm tooling, offers a broad range of grippers designed specifically for collaborative and light industrial robotic applications. We'll use OnRobot's lineup as a reference due to their comprehensive suite of flexible grippers, quick deployment, and reduced programming time - all ideal for pick-and-place applications.
Key Factors to Consider When Choosing a Gripper
Selection of the right gripper, the critical interface between the robot and the task, is paramount. Here are the key factors you should consider:
Gripper Types and Their Applications
These are ideal for diverse product ranges due to their programmable gripping forces and widths. RG2 and RG6 two-finger grippers and RG2FT grippers, for delicate parts requiring precise forces, are some excellent examples.
For cylindrical parts, OnRobot’s 3FG15 is an excellent choice with its high gripping force, large stroke range, and adjustable fingers.
OnRobot’s electric vacuum grippers, including VG10, VGC10, and VGP20, offer versatility and reliability, making them perfect for various pick-and-place applications.
Certain products require specialized grippers for optimal performance, like MG10 magnetic grippers for ferromagnetic parts and Gecko Single Pad Grippers for flat, smooth, or perforated objects.
Finally, you should decide if your pick and place application requires a single or dual gripper configuration. A dual setup can reduce cycle time, but it also adds complexity to the robot programming. You can see a video of what a dual gripper from OnRobot looks like in this video showing a packaging application with OnRobot and Universal Robots
