Automatic winding device for cell core

Abstract

An automatic winding device for cell core includes a mounting seat, a locking cap mounted on one end of the mounting seat, a winding assembly driving mechanism mounted on the other end of the mounting seat and a winding assembly. The winding assembly comprises two winding needles and two winding plates. One end of the winding needle is fixed to the winding driving mechanism and the other end thereof opposite to the locking cap. One end of the winding plate is fixed to the winding driving mechanism and the other end thereof opposite to the locking cap. Two winding plates are disposed on both sides of the pair of winding needles respectively and contact to the pair of winding needles separably. One side of one winding needle has a concave portion and one side of the other winding needle has a convex portion that fits into the concave portion separably. A first protrusion is formed on the end of each winding needle opposite to the locking cap and a second protrusion is formed on the end of each winding plate opposite to the locking cap. A groove and a ring groove are formed in the locking cap in sequence, the first protrusion of the winding needle is locked in the groove and the second protrusion of the winding needle is locked in the ring groove.
