Common Robots supplies a variety of UR licensed grippers via UR+ –a world ecosystem of parts, software program, and utility kits which have been validated and licensed to be mechanically, electrically and digitally appropriate with cobots from Common Robots.
At first, the sheer number of grippers accessible can appear daunting, particularly should you’re new to automation. There are electrical grippers, pneumatic grippers, delicate grippers and vacuum grippers. There are 2-finger and 3-finger grippers, magnetic grippers, mechanical grippers and adaptive grippers, and every gripper supplies distinctive benefits in help of your machine tending, materials dealing with and meeting purposes.
This text is about parallel grippers, so should you’re at a extra preliminary stage in your gripper journey and also you’re questioning ‘What are the forms of grippers?’ attempt studying this text first. (If you’re searching for an outline of among the variations between grippers and need to know the way 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 after they open and shut. In operation, the fingers shut onto the workpiece, grip it during the duty and launch the thing when required. The robotic gripper mechanism present in parallel grippers makes them an excellent match for dealing with elements with predictable shapes and they’re usually chosen for machine tending and decide & place sort purposes. Parallel grippers are one of the widespread gripper varieties within the UR+ ecosystem on account 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 manner that the round movement of the motor is translated right into a linear movement. In the meantime, pneumatically-powered parallel grippers use air strain to open and shut the gripper’s fingers.
Parallel grippers are additionally present in ‘mechanical gripper’ and ‘adaptive gripper’ types. The time period ‘mechanical gripper’ refers to any industrial gripper that makes use of movable levers (or ‘fingers’) to understand objects. Mechanical grippers provide dependable efficiency in all types of producing purposes from machine tending to meeting, however adaptive grippers are extra versatile, since they allow your robotic to choose 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 complicated mechanism that grasp the workpiece with three fingers which can be offset by 120°. In operation, the fingers slide the workpiece to the gripper’s centre to soundly grasp the thing. In the meantime, angled grippers are so-called as a result of they use fingers that method the gripper from quite a lot of angles (e.g. 80° or 30°). For some purposes, akin to when there isn’t area for a parallel gripper to open and shut efficiently, angled grippers would be the better option.
Now that we’ve coated among the fundamentals, let’s check out among the UR licensed parallel grippers accessible via UR+.
Robotiq’s Hand-E gripper supplies a 50-mm parallel stroke, which makes it ideally suited 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. Out there in each twin and single configurations and specifically designed to be used with collaborative robots, Hand-E additionally supplies adjustable pressure, 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 signifies that it is ready to autonomously modify to many various kinds of merchandise of various shapes and sizes.
