PIEZOELECTRIC SENSORS MAKE MINIATURE JOINING MODULE
SENSITIVE AND PRECISE.
The new NCFT Type 2157A electromechanical joining module from Kistler Instruments (www.kistler.com) has been designed specifically for applications where precise positioning and reliable repeatability must be combined with very small joining forces.
Typically, the new module will be ideal for manual and automated assembly of small and miniature components such as inserting small bearings and gear wheels into miniature gearboxes. Based on the well proven design of Kistler's large joining modules, the new module uses integrated force-displacement monitoring to achieve 100% quality assurance throughout the joining phase.
The integration of the piezoelectric force sensor allows each module to cover two switchable measuring ranges. Three options are available, each offering two switchable force ranges up to a maximum of 0.25 kN, 0.5 kN and 1 kN. The exceptionally high resolution of 0.5 µm combined with a stroke speed of up to 300 mm/s maintains operational precision whilst enabling fast joining cycles and short return stokes. The small size of the new module and simplicity of installation allow high-density configuration of assembly jigs. The associated force-displacement monitoring system displays the force-displacement curve in real time and the programmable analysis window allows all phases of the joining process to be continuously evaluated.
The new addition to the Kistler range of joining electromechanical modules brings the total range to four type series covering joining forces from 0.25 kN to 300 kN.
