A rotary gripper module is a compact module that is used for handling small parts in various industries. This rotary gripper module is a compact package of integrated gripper and rotation functions. A rotary gripper module consists of two units: one unit is for providing a gripping function, and another unit is for providing a rotating function. The main advantage of a rotary gripper module is that, it can be used for gripping and rotating small to medium work pieces in low contamination environments and at places where space is limited. A rotary gripper module has a variable rotation range along with adjustable angle property. The rotary motion is implemented with the use of a stepper motor, while the gripping action is achieved with the help of a stepper motor or pneumatically using a cylinder. Rotary gripper modules can be used in different applications, such as unloading and loading work pieces, insertion operations in assembly processes, and the picking of finished products in packaging units.
