ABSTRACT:
An apparatus and a method for testing belt tension of a belt drive for a product such as a washing machine or the like, and more particularly to an apparatus and a method for automatically testing initial belt tension of the belt drive on an assembly line. The belt tension testing apparatus comprises a rod cell for detecting a signal indicating a pressure generated due to a belt tension of a belt of a belt drive; a lift drive for moving the rod cell to a position where the belt is to be pressed by the rod cell; a pressing drive for moving the rod cell to press the belt; measuring means for measuring a distance by which the rod cell is moved by the pressing drive; conveyer means for conveying the belt drive; a fixing support for fixing the belt drive at a working position; and a control and display device for controlling operations of actuators of the lift drive, the pressing drive, and the fixing support, and for determining and displaying whether the belt tension is within an appropriate value range. The apparatus can accurately test the belt tension and thus increases the reliability of the test result, and can improve the productivity of a product to which the belt drive is mounted.
