Abstract:
PURPOSE: An apparatus and a process for fabricating a cathode plate of a Ni-MH battery are provided to maximize productivity of the battery by manufacturing the cathode plate of Ni-MH battery via an automatic batch process. CONSTITUTION: A cathode plate fabrication apparatus comprises a cathode plate feeding unit(3), first press unit(9), an active material eliminating unit(13), a tap feeding unit(19), a tack welding unit(25), a cutting unit(23), a main welding unit(27) and second press unit(31). The feeding unit(3) supplies cathode plate raw material(6) from a cathode plate roll(5). The first press unit(9) cuts the cathode plate raw material(6) into a certain length to form rectangular unit cathode plates(7). The active material eliminating unit(13) rams the cathode plate(7) in one corner portion to eliminate an active material from the cathode plate raw material(6). The tap feeding unit(19) supplies a tap strip from a tap strip roll. The tack welding unit(25) tack welds an end portion of the tap strip from the tap feeding unit(19) to the upper and lower sides of the cathode plate(7). The cutting unit(23) cuts the tack welded tap strip into a certain length to form rectangular taps, which are finish welded by the main welding unit(27) and cut into a final shape by the second press unit(31).

PURPOSE: An apparatus and process for fabricating an anode plate of a Ni-MH battery is provided to maximize productivity of the battery by manufacturing the anode plate of Ni-MH battery via an automatic batch process. CONSTITUTION: An anode plate fabricating apparatus comprises an anode plate feeding unit(3), an active material eliminating unit(13), a tap feeding unit(19), a tack welding unit(25), a cutting unit(23), a main welding unit(27), a calendar rolling unit(28) and a press unit(31). The feeding unit(3) has a magazine(5) where a cut anode plate(7) is manually stacked. The active material eliminating unit(13) has an ultrasonic cleaner(11) for eliminating an active material from an edge portion of the anode plate(7). The tap feeding unit(19) supplies a tap strip from a tap strip roll. The tack welding unit(25) tack welds an end portion of the tap strip supplied from the tap feeding unit(19) to the upper and lower sides of the anode plate(7) where the active material is eliminated. The cutting unit(23) cuts the tack welded tap strip into a certain length to form rectangular taps, which are finish welded by the main welding unit(27) and pressed by the calendar rolling unit(28). The press unit(31) cuts the calendar rolled anode plate(7) into a certain shape.
