Grippers in robotics make a significant contribution in robot assembly. Grippers serve a purpose of clutching and working with the objects in the working cycle. In most cases, robots clutch objects, such as workpieces, to load or unload them from a mechanism at various stations. Manufacturers can also design grippers to meet specific standards provided by the workpieces. This article is all about understanding robotics grippers:
Definition
A gripper is a fitting device used in machines or robotic arms that is designed to grip, lift, control, or move objects from one place to another. Gripper acts as the ‘hand’ or end effector of the robotic manipulator or an automatic system to let the robotic device grip or release things that it comes across.
Types
There have been several types of Grippers developed for the different objects and industrial activities. In this way, the End-of-arm has to be in contact with the objects and interact with them, which are called their grippers. The four main types of robot grippers are: vacuum grippers, hydraulic grippers, pneumatic grippers and servo electric grippers. The staggering number of different types of grippers is easily comprehensible in the light of all the different kinds of objects, ranging from textiles to electronic components to car parts, that robots can grip. For instance, when it comes to directly manipulating fragile food items, a small, supple gripper would be preferred. Packaging and palletizing operations, on the other hand, which require arranging a stack of product boxes. It would warrant the use of a large-sized gripper fitted with huge suction cups.
Features
Payload: The term payload encompasses the maximum total weight which the robot arm including the gripper can carry. Just as a person’s arms and hands limit the weight they can lift at the gym. A robot lifts weights until it experiences a mechanical failure. Thus, in selecting a robot hand, one has to factor in the payload of the robotic arm and the gripper in question.
Automation
Due to the nature of machine tending, which entails a lot of repetition. it is possible to introduce automation by the use of collaborative robots. Instead of employing people to carry out these physical jobs, why not equip collaborative robots that can grip elements and perform machining operations. This will not only lead to more uniform outcomes but will also enable your employees to focus on more productive activities that are more appropriate to their skills. For example, monitoring the programming and functioning of the collaborative robot.
3D printing
There are many design platforms like Grabcad, Autodesk Academy et cetera. They contain ready-to-manufacture designs of semi-professional 3D printed robot grippers. Such tools operate only where they do not require excessive strength and handle light enough objects. Thus, restricting these grippers to semi-professional and academic settings.
After understanding robotics grippers, experts call them the unsung heroes of robotic arm automation, as they enable these machines to perform a wide range of tasks with precision and efficiency. Whether it’s the adaptability of finger grippers, the strength of hydraulic grippers, or the precision of vacuum grippers. Each type has its unique set of advantages and applications.
