Common Robots offers a variety of UR licensed grippers by way of UR+ –a world ecosystem of parts, software program, and utility kits which have been validated and authorized to be mechanically, electrically and digitally appropriate with cobots from Common Robots.
At first, the sheer number of grippers accessible can appear daunting, particularly when 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 offers distinctive benefits in help of your machine tending, materials dealing with and meeting purposes.
This text is about parallel grippers, so when you’re at a extra preliminary stage in your gripper journey and also you’re questioning ‘What are the sorts of grippers?’ attempt studying this text first. (If you’re in search of an summary of a number 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 after they open and shut. In operation, the fingers shut onto the workpiece, grip it at some point of the duty and launch the item 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 choose & place sort purposes. Parallel grippers are probably the most widespread gripper varieties within the UR+ ecosystem as a consequence of their ease of use.
Parallel grippers may 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’ kinds. 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 types of producing purposes 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 might be offset by 120°. In operation, the fingers slide the workpiece to the gripper’s centre to securely grasp the item. 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 purposes, equivalent to when there isn’t house for a parallel gripper to open and shut efficiently, angled grippers stands out as 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 accessible by way of UR+.
Robotiq’s Hand-E gripper offers a 50-mm parallel stroke, which makes it ultimate 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 offers adjustable drive, rounded edges, self-locking functionalities, and different options that make it protected to make use of in shut proximity to people. The Hand-E is actually adaptive, which signifies that it is ready to autonomously modify to many various kinds of merchandise of various shapes and sizes.
