vacuum grippers Nowadays, automation has become ubiquitous in manufacturing. More manufacturers are using industrial robots in their production lines. Industrial robots tend to come with a robotic arm and a gripper or end effector.

A robotic grippers is definitely an electrical finish of arm tooling device that manipulates objects while using finish of their arms. It features a device having a controllable hands that grasps and releases a multitude of materials and parts with an automatic process. Most robot grippers have mounting surfaces rich in precision for attaching the finger tooling tool and gripper to some automatic arm.

The important thing significant benefits of utilizing a robot gripper is reducing part damage during production and packaging. Arm tooling devices finish are exposed to these products. Hence, it’s necessary to pick the best type of gripper for company’s operation.

Grippers are operated by electricity, vacuum or compressed air. This partially comprises the 4 groups of automatic grippers vacuum, hydraulic, pneumatic and servo-electric grippers. If you wish to pick a qualified robot gripper for the company, it is advisable to select a gripper according to its handling application and also the materials in the manufacturing. Let’s evaluate the four groups of grippers and probably the most common kinds of grippers currently available.

Groups of Grippers

Vacuum Grippers

Fundamental essentials standard finish f arm tooling devices within the manufacturing industry due to their higher level of versatility. These grippers make use of a memory suction cup or perhaps a rubber to get products. A couple of vacuum grippers make use of a closed-cell foam rubber as opposed to a suction cup for choosing parts or materials.

Hydraulic Grippers

These kind of grippers is fantastic for operations that require plenty of pressure. There is a large amount of strength that is produced by hydraulic pumps which could supply to 2000psi. However, however, this equipment is untidy due to the oil in the pumps. Additionally they require frequent maintenance since the gripper will get broken frequently because of the high pressure used throughout the application.

Pneumatic Grippers

These grippers are very well recognized for their lightweight and small size. The lightweight causes it to be well suited for places with limited property, for example small companies. Pneumatic grippers could be closed or open. They’re frequently known as “bang-bang” mechanism because of the noise produced throughout the operation.

Electric Grippers

These kinds of grippers are simple to control, so that they tend to be more suited to industrial settings. Electronic motors let the movement from the robot gripper. They are highly flexible grippers. Their versatility accommodates different material tolerance when they’re handling parts and materials. They’re also neat and relatively cost-effective.

Common Kinds of Robot Grippers

The 3-Jaw Robot Gripper

These finish of arm tooling devices can be found in angular and parallel variants. They’re generally employed for obtaining material and parts via a round surface. As suggested by its name, the 3-jaw robot gripper has three jaws with 120 levels space in between each jaw. The jaws of the robot gripper relocate symphony. It possesses a secure grip from the part by centring it during its closing or opening motion,

Bellows Robot Gripper

This kind of robot is made to grip objects having a round surface. It uses an elastomer bladder to understand the part. Compressed air inflates it, which makes it expand and grip the round part. It’s also made to release the part once the compressed air is released, and also the bladder deflates.

Collet and Expanding Mandrel Robot Gripper

This finish of arm tooling system is also made to grasp round surfaces. However, it relies on a straight line motion along with a wedge contour around open or close its metallic fingers to grip the I.D. or O.D. from the part firmly.

Parallel Motion Two-Jaw Robot Gripper

This is among the simplest grippers which can be used in lots of applications. It’s available in Pneumatic, electric and hydraulic versions and quite a number of sizes, weights, forces, and stroke ranges. They’re generally accustomed to grasp parts with two parallel flat surfaces. They grip parts using either the closing or opening motion. The parallel motion two-jaw robot gripper also offers an angular two-jaw version with 90-degree pivoting fingers.

O-Ring Robot Gripper

This robot is specifically made to handle O-ring seals. It operates much like a 3-jaw parallel gripper. Its 6-8 fingers radially expand and carry the inner diameter from the part or material. Once it’s extended, the O-ring is positioned right into a groove in the finish from the shaft.

Needle Robot Gripper

This variant of robot gripper is rare. It is made to get woven sheets or porous materials like textiles by piercing with the surface with multiple sharp needles.

Multi-Finger and Adaptive Robot Gripper

This can be a recent robot model made to enable robots to understand various items that could formerly ‘t be manipulated. This robot grips irregular, spherical or soft objects and provides the controller pressure feedback to avoid harm to the various components or materials.

Advances in Robot Grippers

As the use of robot grippers increases in e-commerce, manufacturing, and put applications, there’s been a requirement for robot grippers with enhanced abilities, especially collaborative robots that may handle a greater diversity of objects and perform more repetitive tasks. A few of the calls for advanced characteristics of robot grippers include:


Future robot grippers should think about the needed precision for conducting a particular task. The grippers should be precisely sized or programmed to handle size, hardness and weight from the moved products. Some companies have previously begun offering customizable finish effectors for particular materials.

Robot Grippers with Improved Skill

Adding axis and enhancement of torque sensors have enhanced the intelligence of motion grippers and also the abilities from the robots to control fragile objects, particularly when the robots work near to Humans.

Main Point Here

You will find four kinds of robot grippers you could use for production inside your company hydraulic grippers, servo-electric grippers, pneumatic grippers and vacuum grippers. Not every robot grippers might be appropriate for the organization. When choosing a robotic gripper for the company, choose one in line with the handling application and kind of fabric your small business is handling.
