How to choose the right gripper for automation? In the world of industrial automation, choosing the right gripper is crucial to ensuring efficiency, reliability and process quality. A sub-optimal selection can lead to gripping errors, premature wear or slowdowns. In this article, we look at the technical criteria to consider when choosing the right gripper for your application.

For the part to be handled, it is important to know its mass, centre of gravity, dimensions, material, shape, possible damage due to gripping, and information on working conditions such as the type of chips, operating temperature, the presence of fumes or cooling/washing fluids, and the presence of chemicals.

OMIL offers a wide range of solutions: 2 parallel jaws, 3 self-centring jaws, 4 self-centring jaws, 2 angular jaws and 2 radial jaws. OMIL also offers solutions with a central hole for 3 and 4 jaws.

Defining the orientation of the gripper is essential for understanding the loads and force.

Among the first things to determine is the gripping mode, which could be friction, geometric or prismatic, the distance of the gripping point from the upper plane of the gripper and the width of the piece at the gripping point. To determine the stroke, it is necessary to understand how many pieces must be handled with the same gripper and add the extra stroke due to the geometry of the upper jaw and the robot's approach. Also, be aware that the maximum allowable pressure may limit the gripping force. The size of the footprint between the jaw and the part can be decisive in some conditions. Pay particular attention to offset grips and the position of the part's centre of gravity.

The choice of jaw material is important in determining the friction between the part and the upper jaws. Good friction reduces the clamping force. Temperature, fluids and chemicals must be taken into account.

It is important to know the direction and maximum acceleration of all axes.

We recommend applying a minimum factor of 1.5-2 depending on the complexity of the handling operation, or higher if it could pose a danger to people. In this case, we invite you to consider the use of additional devices in the event of a drop in pressure. OMIL can offer MC (closing) or MA (opening) spring-loaded safety devices or VMP pressure safety valves.

Sometimes it is possible to apply products of different sizes if we only consider the gripping force, which is why we must always check the maximum permissible loads on the grippers. You will find the permissible forces and moments in the catalogue. The values indicated are static. To convert them to dynamic values, divide them by 3. Also consider the external loads associated with the machining operations. It is important to know the mass of the grippers because it could affect the life of the product.

Other factors should also be considered for correct handling, such as the discharge of the claws, the rigidity of the structure, the quality of the geometries, any bending of the piece, the necessary repeatability, the required concentricity, the possible application of accessories such as the spring-loaded presser, the number of clamps needed to handle the piece, and the possible angle of the prism (a smaller angle requires less gripping force but may require a longer jaw stroke).

Our extensive experience allows us to offer you the best advice, optimised product performance, product quality and cutting-edge production systems. We offer a wide range of solutions for various environments, including grippers with a stroke of up to 200 mm, protection up to IP 67 rating, 4-jaw self-centring grippers, pneumatic or hydraulic solutions, operating temperatures up to 130°C, through holes up to 60.5 mm, and jaw lengths up to 800 mm. In every situation, our technical staff will guide you step by step to help you understand in detail how to choose the right gripper for your automation needs.

If you cannot find a product in our wide range, OMIL is available as a partner to develop solutions tailored to the customer's application. Customisation and special products characterise our customer care culture. Over the years, we have developed grippers for gripping parts up to 1000°C controlled with glycol water, 4-jaw grippers with long stroke and MCX bar passage, and many other tailor-made solutions.

TrueConnect™ revolutionises the way tool changers integrate into industrial processes. RSP's patented device ensures quick and safe connection of tools, which is crucial for optimising robot productivity. With a load capacity of up to 1,500 kg and a clamping cycle of less than 0.3 seconds, TrueConnect™ not only speeds up operating time, but also improves safety and efficiency in high-intensity production environments.

The innovative design, based on uniform load distribution by means of locking balls that fit into spherical grooves, ensures a solid and reliable coupling. This solution surpasses traditional clamping methods, offering greater strength and consistent precision over time. In addition, the ability to repeat the alignment exactly makes the system extremely versatile, eliminating the need for complex manual adjustments.

Secure 3-step clamping:

1) Centring and orientation: the locking balls enter the cavities (spherical grooves) of the TA.
2) Start of clamping, secure position: the balls enter the next stage of the groove, reaching a secure position.
3) Completion of locking: the final position creates a complete lock, held in place by the high friction and locking balls.

By adopting TrueConnect™, companies can significantly reduce downtime and increase the productivity of their robots, while ensuring high safety standards. In an ever-changing industrial world, RSP is the key to agile, safe and innovative production. TrueConnect™ is the ideal choice for those looking for uncompromised reliability, efficiency and performance.
