Common Robots gives a variety of UR licensed grippers via UR+ –a worldwide ecosystem of elements, software program, and utility kits which were validated and licensed to be mechanically, electrically and digitally suitable with cobots from Common Robots.
At first, the sheer number of grippers obtainable can appear daunting, particularly if you happen to’re new to automation. There are electrical grippers, pneumatic grippers, comfortable 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 assist of your machine tending, materials dealing with and meeting functions.
This text is about parallel grippers, so if you happen to’re at a extra preliminary stage in your gripper journey and also you’re questioning ‘What are the kinds of grippers?’ attempt studying this text first. (In case you are in search of an outline of a number of the variations between grippers and wish 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 business robotic gripper that includes two fingers that stay parallel after they open and shut. In operation, the fingers shut onto the workpiece, grip it in the course of the duty and launch the thing when required. The robotic gripper mechanism present in parallel grippers makes them a terrific match for dealing with elements with predictable shapes and they’re usually chosen for machine tending and decide & place sort functions. Parallel grippers are one of the in style gripper varieties within the UR+ ecosystem as a result of their ease of use.
Parallel grippers might 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 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 supply dependable efficiency in all kinds of producing functions 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 strategy the gripper from a wide range of angles (e.g. 80° or 30°). For some functions, reminiscent of when there isn’t house for a parallel gripper to open and shut efficiently, angled grippers would be the more sensible choice.
Now that we’ve coated a number of the fundamentals, let’s check out a number of the UR licensed parallel grippers obtainable via UR+.
Robotiq’s Hand-E gripper gives 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. Obtainable in each twin and single configurations and specifically designed to be used with collaborative robots, Hand-E additionally gives 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 actually adaptive, which signifies that it is ready to autonomously regulate to many various kinds of merchandise of various styles and sizes.
