Common Robots gives a variety of UR licensed grippers by way of UR+ –a worldwide ecosystem of parts, 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 out there can appear daunting, particularly for those who’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 assist of your machine tending, materials dealing with and meeting purposes.
This text is about parallel grippers, so for those who’re at a extra preliminary stage in your gripper journey and also you’re questioning ‘What are the sorts of grippers?’ strive studying this text first. (In case you are in search of an outline of a number of 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 sort 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 in the course of the duty and launch the article when required. The robotic gripper mechanism present in parallel grippers makes them an amazing match for dealing with elements with predictable shapes and they’re usually chosen for machine tending and choose & place kind purposes. Parallel grippers are one of the vital standard gripper sorts 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’ varieties. The time period ‘mechanical gripper’ refers to any industrial gripper that makes use of movable levers (or ‘fingers’) to know objects. Mechanical grippers supply 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 are offset by 120°. In operation, the fingers slide the workpiece to the gripper’s centre to securely grasp the article. 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 purposes, equivalent to when there isn’t house for a parallel gripper to open and shut efficiently, angled grippers often is 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 out there by way of UR+.
Robotiq’s Hand-E gripper gives a 50-mm parallel stroke, which makes it perfect 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 power, 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 modify to many various kinds of merchandise of various dimensions and shapes.
