INSULATING COATING OVERLAY CONTROL SYSTEM AND INSULATING COATING OVERLAY CONTROL METHOD

The present technology relates to an insulation-coating overlay control system, and the system includes: an insulation coater which coats an insulating material to allow the insulating material to cover a partial region of a coated part, on which an electrode slurry has been coated, and a non-coated part, on which the electrode slurry has not been coated, in an electrode plate, along a boundary part between the coated part and the non-coated part; an insulation-coating width measuring means which measures an overlay width, which is a width of an overlay region where the insulating material has been coated on the coated part, and a non-coated part coating width, which is a width of a region where the insulating material has been coated on the non-coated part; an insulation coater moving means which moves the insulation coater; and a controller which controls the insulation coater moving means to adjust the overlay width by comparing the measured overlay width with a predetermined overlay width setting range or an overlay width reference value. [0002] The present invention also relates to an electrode plate for a secondary battery, and an insulation-coating overlay control method.
