- Mechanical Grippers: These grippers have mechanical fingers or jaws that physically grasp and hold objects. These are commonly used for handling a wide range of materials, especially for pick-and-place, machining, and assembly tasks.
- Pneumatic Grippers: Operated by compressed air, pneumatic grippers use air pressure to open and close the gripper jaws. These are suitable for applications where a strong and quick grip is required, like pick-and-place, machine tools, assembly, and workpiece machining operations.
- Hydraulic Grippers: These are like pneumatic grippers but use hydraulic fluid instead of air for operation. They provide a powerful and controlled grip, often used in heavy-duty applications. Industries dealing with heavy and bulky materials, such as construction and logistics, often turn to hydraulic grippers. These grippers provide the necessary strength to securely grasp and manipulate substantial loads, contributing to increased efficiency in material handling processes. They are also ideal for lifting heavy loads on production lines.
- Electric Grippers: This type of gripper uses electric motors for opening and closing the gripper fingers. They offer extremely precise control and are suitable for applications where accuracy is crucial, like machine tending or pick-and-place. Some electric grippers can handle many shapes, which makes them ideal for such tasks. Despite lacking the gripping power of their hydraulic counterparts, electric grippers are often used in situations requiring high speed and a light to moderate grip. For example, in the electronics sector, where precision is critical, electric grippers offer accurate control over the gripping force and position, ensuring careful handling of fragile electronic components.
- Magnetic Grippers: As their name implies, these grippers use magnetic fields to hold ferrous objects securely and allow for handling metallic materials without needing physical contact. Besides material handling, magnetic grippers are also used for palletizing and bin picking for items like auto parts. They are also used for palletizing metal containers such as drums of solvents or cans of paint.
- Vacuum Grippers: The grippers employ suction cups to hold objects securely and are effective for handling non-rigid or porous materials like cardboard, fabrics, or plastic sheets. They are particularly effective for large, flat items like foam insulation, boards, or panels. Vacuum-type grippers are also commonly used in the food and beverage industry to pick up and transfer food products without causing damage. Their non-contact approach ensures hygienic handling, making them well-suited for industries where cleanliness is paramount.
- Adaptive Grippers: Designed with flexible and adaptable materials to handle objects of various shapes and sizes, these are the most ‘hand-like’ grippers. They use two or more finger-like parts to grasp items with a pincer-like motion. They are ideal for applications where the gripper needs to conform to irregular surfaces of items that aren’t at risk of damage by applied pressure or puncture.
- Finger Grippers: These common grippers have multiple fingers that can adapt to the shape of the object being handled. Suitable for applications requiring a gentle and flexible grip, these are often used for bin picking, grasping parts in a confined space, or moving objects with simple shapes.
- Parallel Grippers: This aptly named type of gripper features parallel jaws that move simultaneously to grip objects – the ‘fingers’ will remain parallel to each other as the gripper opens and closes. They are most often used in pick-and-place applications for efficiency.
- Angular Grippers: As you may expect, these grippers have jaws that can move at an angle, providing additional flexibility in gripping due to the angular stroke’s ability to create a wider opening. These are especially useful for handling off-centered items or objects with irregular shapes.
The choice of gripper depends on factors such as the type of material being handled, the required precision, the speed of operation, and the application requirements – which can vary greatly. Manufacturers choose the grippers that best suit their specific needs, including increased automation, improved production rates, and enhanced operational capabilities.
