Common Robots supplies a variety of UR licensed grippers by UR+ –a world ecosystem of parts, software program, and software kits which were validated and licensed to be mechanically, electrically and digitally appropriate with cobots from Common Robots.
At first, the sheer number of grippers obtainable can appear daunting, particularly in the event you’re new to automation. There are electrical grippers, pneumatic grippers, smooth 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 assist of your machine tending, materials dealing with and meeting functions.
This text is about parallel grippers, so in the event you’re at a extra preliminary stage in your gripper journey and also you’re questioning ‘What are the forms of grippers?’ strive studying this text first. (If you’re searching for an outline of a number of the variations between grippers and wish 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 sort 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 throughout the duty and launch the article when required. The robotic gripper mechanism present in parallel grippers makes them an incredible match for dealing with components with predictable shapes and they’re usually chosen for machine tending and choose & place sort functions. Parallel grippers are one of the crucial well-liked gripper sorts within the UR+ ecosystem attributable to their ease of use.
Parallel grippers will 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 means 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’ 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 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 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 article. In the meantime, angled grippers are so-called as a result of they use fingers that strategy the gripper from a wide range of angles (e.g. 80° or 30°). For some functions, corresponding to when there isn’t area for a parallel gripper to open and shut efficiently, angled grippers could be the more sensible choice.
Now that we’ve lined a number of the fundamentals, let’s check out a number of the UR licensed parallel grippers obtainable by UR+.
Robotiq’s Hand-E gripper supplies a 50-mm parallel stroke, which makes it excellent 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 supplies 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 modify to many various kinds of merchandise of various styles and sizes.
