Abstract:
An assembling machine for a negative electrode plate for nickel metal hydroxide batteries comprising:an electrode plate feeding unit supplying a source material of the negative electrode plate from an electrode plate roll;a blanking press unit forming a rectangular negative electrode plate unit by cutting the source material of the negative electrode plate with a predetermined length;an active material removing unit removing an active material forming a surface of the negative electrode plate by striking an active material removal area of the negative electrode plate, wherein the active material removing unit comprises a holding portion having a finger portion for holding the negative electrode plate, a twin cylinder connected to the finger portion through an upper hand portion for sliding the finger portion in an axial direction, and a rotary cylinder rotating the finger portion in a right angle and a negative electrode plate striking portion having a vibration hammer that reciprocates by a linear motor for striking the active material removal area of the loaded negative electrode plate that is lifted to a striking position by the rotation of the finger portion and a stopper for holding an opposite side of the above active material removal area;a tab feeding unit supplying a tab strip from a tab strip roll;a tact welding unit that temporarily welds the edge of the tab strip transferred from the tab feeding unit to upper and lower faces of an active material removal area of the negative electrode plate;a cutting unit forming a rectangular tab by cutting with a predetermined length the tab strip that is temporarily welded to the active material removal area of the negative electrode plate;a finish welding unit that fully welds the temporarily welded tab; anda second blanking press unit that finally cuts with a desired shape the negative electrode plate that is fully welded to the tab.
