According to the requirements of automatic wire bonding machine, CoreMorrow produces piezo clamp, which is designed and developed for clamping wire. It feaures a simple structure, fast response and high resolution. 

Priciple
the structure of piezo clamp is composed of piezo stack, flexible mechanical structure, fixed jaw and adjustable jaw. Piezo stack is installed between clamping jaw and the base. When voltage is applied to piezo stack, the output displacement of the piezo stack is amplified by the lever arm of the clamping jaw and outputed in the top end of the clamp. Clamp closed. after the voltage is removed, the of clamp jaws return to initial position, and the clamp is opened to allow the lead to pass freely.
