GAP ADJUSTMENT FOR AN ULTRASONIC WELDING SYSTEM

摘要

A system and method for adjusting the gap between a horn (700) and an anvil (704) in an ultrasonic welding system includes the act of positioning a horn proximal to an anvil, so that a gap is established between the horn and the anvil. A force is applied to the horn, so as to urge the horn toward the anvil. A deformable stop (718) is positioned at a location, such that application of the urging force causes a member (716) operatively connected to the horn to abut the deformable stop, and to deform the stop. The urging force is iteratively adjusted during operation of the horn, so as to adjust the extent of the deformation of the deformable stop, and to maintain the gap between the horn and the anvil substantially constant.
