Common Robots gives a variety of UR licensed grippers by UR+ –a worldwide ecosystem of elements, software program, and utility kits which have been validated and authorized to be mechanically, electrically and digitally suitable with cobots from Common Robots.
At first, the sheer number of grippers accessible can appear daunting, particularly in case you’re new to automation. There are electrical grippers, pneumatic grippers, tender grippers and vacuum grippers. There are 2-finger and 3-finger grippers, magnetic grippers, mechanical grippers and adaptive grippers, and every gripper gives distinctive benefits in help of your machine tending, materials dealing with and meeting functions.
This text is about parallel grippers, so in case you’re at a extra preliminary stage in your gripper journey and also you’re questioning ‘What are the varieties of grippers?’ strive studying this text first. (In case you are searching for an summary of a few of the variations between grippers and need to understand how vacuum grippers and pneumatic grippers work, for instance, take a look at this text.)
What’s a parallel gripper?
Parallel grippers are a kind of commercial robotic gripper that includes two fingers that stay parallel once they open and shut. In operation, the fingers shut onto the workpiece, grip it all through the duty and launch the item when required. The robotic gripper mechanism present in parallel grippers makes them an awesome match for dealing with components with predictable shapes and they’re usually chosen for machine tending and decide & place sort functions. Parallel grippers are one of the crucial standard gripper varieties within the UR+ ecosystem because of their ease of use.
Parallel grippers could be powered by electrical energy or pneumatics. Electrical parallel grippers use electrical energy to energy motors. The motors are linked to the gripper’s fingers in such a approach that the round movement of the motor is translated right into a linear movement. In the meantime, pneumatically-powered parallel grippers use air stress to open and shut the gripper’s fingers.
Parallel grippers are additionally present in ‘mechanical gripper’ and ‘adaptive gripper’ varieties. The time period ‘mechanical gripper’ refers to any industrial gripper that makes use of movable levers (or ‘fingers’) to know objects. Mechanical grippers provide dependable efficiency in all kinds of producing functions from machine tending to meeting, however adaptive grippers are extra versatile, since they permit your robotic to select up all kinds of various objects with out the end-user having to step in and alter the gripper.
Parallel grippers shouldn’t be confused with 3-finger or angled grippers. 3-finger grippers have a extra advanced mechanism that grasp the workpiece with three fingers which are offset by 120°. In operation, the fingers slide the workpiece to the gripper’s centre to soundly grasp the item. In the meantime, angled grippers are so-called as a result of they use fingers that method the gripper from a wide range of angles (e.g. 80° or 30°). For some functions, akin to when there isn’t area for a parallel gripper to open and shut efficiently, angled grippers could be the more sensible choice.
Robotiq’s Hand-E gripper gives a 50-mm parallel stroke, which makes it supreme for precision meeting duties. The gripper’s sealed design is rugged sufficient to make sure reliability within the hardest manufacturing situations, together with CNC machining. Accessible in each twin and single configurations and specifically designed to be used with collaborative robots, Hand-E additionally gives adjustable drive, rounded edges, self-locking functionalities, and different options that make it secure to make use of in shut proximity to people. The Hand-E is really adaptive, which implies that it is ready to autonomously regulate to many several types of merchandise of various dimensions and shapes.
