Patent ID: 7895735

Claim:
An apparatus for mounting a magnetic element to a retainer, comprising: a movable arm; an electromagnet comprising a first end attached on the movable arm, and a second end; a first controller for controlling magnetic polarity of the electromagnet to oppose that of the magnetic element at a first time and to match that of the magnetic element at a second time; a glue dispenser comprising a plate body and a second controller, the plate body comprising an inner space containing glue, a through hole defined between a first surface and a second surface on opposite sides thereof, and a plurality of spaced glue outlets in the first surface and communicating with the inner space, the second end of the electromagnet engaging the through hole to attract the magnetic element on the first surface of the plate body with the glue outlets surrounding, and repelling the magnetic element to the retainer, the second controller configured for ejecting the glue out of the inner space of the plate body via the glue outlets, thereby adhesively mounting the magnetic element to the retainer.
