How to choose the right robot gripper for your work environment

The best way to select a gripper for the type of part you need to handle depends on your assembly or machining process and part feed process. The environment in which the gripper will work should play an essential role in selecting the gripper. Details more points about the environment you should check before purchasing a gripper.

Temperature

In most cases, the temperature is the limiting factor in your application and is usually too hot rather than too cold. If the fixture works near a welding torch or hot casting equipment, the requirements are different than if it is in a temperate environment. Generally, the fixture manufacturer will provide the optimum operating temperature range. This range should be adhered to due to different factors. Some gripper components can be severely damaged if operated outside their operating range.

Even if we talk about temperature, explosive environments should be considered when selecting a gripper. Some of the powders or gases used in some plants there will explode when they come in contact with motors or sparks. This is a minimal factor in your fixture selection because it is about the fixture's function and the plant's safety. I know some of the motors available are compatible with explosive environments. Then you will have to look carefully at the different options for your robot and fixture application.

Fluids

Some applications, such as machine maintenance, typically use large amounts of fluids. Coolant, water, and other fluids can damage your fixtures if not protected as necessary.

If your application involves significant amounts of fluid, you should ensure that the mechanism and electronics (if applicable) are well protected. You should also monitor the amount of fluid the gripper will be exposed to. If there is a large amount of fluid in the application, but your gripper is not exposed to any fluid, you may consider using less protection than if the gripper had to be submerged in fluid.

An IP rating is an excellent way to quantify the type of protection you need. The different ratings will help you monitor your application and determine your needs. All Robot Grippers have an IP 67 rating, which means they are "dustproof" and can prevent water penetration for 1 to 30 minutes.

Cleanliness

Will there be some metal shavings or dust on the robot gripper? Are you using small parts that can get into the gripper mechanism? These are the questions you should ask yourself when looking for a gripper. You should note that IP ratings can also be used for solid intrusion, and make sure you choose a gripper with the required rating for both dust and liquids.

Also, if the process needs to be done in a dirty environment, cleaning would be a good option so that you can clean the gripper regularly. You should note that a clean gripper is related to function and accuracy. If the gripper pad is dirty, accuracy is bound to decrease when gripping parts.

Ask the robot gripper manufacturer

You should explicitly ask your gripper representative or application engineer if your application is suitable for certain types of grippers. This article provides valuable ideas to help you understand what to consider when selecting a gripper for your particular environment.
