  • Coating layer removing apparatus and method for the same
    Patent number: 8309880
    Abstract: The present invention discloses a coating layer removing apparatus and a method for the same. The apparatus of the present invention comprises a transport device displacing an electrode plate; a laser device having a laser head arranged above the displacement path of the electrode plate; and a control center electrically connected to the transport device and the laser device. The method of the present invention comprises mounting an electrode plate on the transport device; using the control center to set the speed of displacing the electrode plate, and program the time interval, count and penetration depths of the laser beams; and using the device of the present invention to form exposed areas equidistantly on the electrode plate. The apparatus of the present invention automatically removes a coating layer with a laser beam without directly contacting the electrode plate. Therefore, the present invention can fast form exposed areas of high quality.
