Micro-Grippers

MICRO-GRIPPERS

SmarAct grippers (SG) are suitable for both micro- and macroscopic applications.
Every gripper consists of two parts (a) a linear positioner (eg. SLC series) and (b) a flexure structure attached to the positioner.

Depending on the application the gripper jaws are exchangeable or permanently welded to the positioner.

Easily exchangeable jaws make your investment future proof. You can always work with exactly the jaw shape most suitable for your application.

Due to the large travel ranges of SmarAct‘s positioners the grippers allow for an opening of up to several millimeters, while maintaining very precise control.
This high precision is particularly important for the manipulation of small and fragile objects.

The internal position sensors of the SLC series are of greatest importance, especially in automated microhandling, because they provide feedback on the success of a gripping process.

Unlike most other micro-grippers, SmarAct grippers are able to hold objects even when there is no power supply, enabling long gripping times without any heat generation.

All grippers can be designed to fit your needs. We look forward to discuss your individual requirements with you.

STANDARD GRIPPER JAWS

For various applications we offer different standard gripper jaws for both, grippers with a fixed gripper structure and with exchangeable gripper jaws. In the image below, you can find a small selection of different jaw shapes, which may also provide some ideas for your jaw design.

Standard gripper jaws are made out of conductive materials like steel or copper beryllium. Other conductive as well as non-conductive materials are available on request.

CUSTOMIZED GRIPPER JAWS

SmarAct offers customized gripper jaws for both, grippers with a fixed gripper structure and with exchangeable gripper jaws. Various structures like parallel grippers, slit apertures as well as cranked jaws have been designed and can be adapted to match your specifications. Like standard gripper jaws, our customized gripper jaws are made of conductive materials like steel or copper beryllium. Other conductive as well as non-conductive materials are available upon request.

For us it is important to produce the optimal gripper for your application, so please feel free to contact us and our experts will help you design your gripper.

We established a few design rules as given below:

  • Please use our default model, which will be provided by us, keep the triangular part and only change the gripper jaws.
  • The minimum concave radius is 0.11 mm.
  • The minimum gap size is 0.22 mm.
  • The material thickness should be 0.3 mm, 0.5 mm, 1.0 mm or 1.5 mm.
  • Please send us the model in SolidWorks or STEP format.
