An automatic filament tensioning device and method with controllable tension force

Abstract

The invention relates to a filament automatic tensioning device and method with controllable tension force, belonging to the field of precision assembly. The device includes a feeding unit, a filament clamping unit, a tension control unit and a filament position adjustment unit; there are two filament position adjustment units, which are used to adjust the position of the filament in the Z direction; the filament There are two clamping units, two tension control units and two filament position adjustment units, with the loading unit as the center and arranged symmetrically from left to right; among them, the filament position adjustment unit is installed on the On the tension control unit; the filament clamping unit is installed on the filament position adjustment unit through the cylinder adapter plate and the cylinder mounting plate. The invention can realize the automatic clamping of the filaments, and can carry out real-time automatic detection and control of the tension force, and can also realize the adjustment of the three degrees of freedom of the filaments, improve the assembly efficiency and assembly accuracy, and can be integrated In automated assembly equipment, assembly consistency is guaranteed.
