摘要： The present disclosure relates to a secondary battery electrode surface pressure cutting device including upper and lower blades configured to cut a secondary battery electrode and using a modularized adjustment module to finely adjust the upper blade. In order to achieve the above-mentioned object, the surface pressure cutting device including an upper blade fixedly fastened to a moving block in a frame, and a lower blade fixedly fastened in a lower blade fixing block, in which the upper blade may cut an electrode while moving upward or downward, and the upper blade fixedly fastened to the moving block may be finely adjusted. The adjustment module includes a threaded part having a protrusion portion formed at one side thereof, a spring fitted with the protrusion portion, an adjustment member having an adjustment guide formed at a side opposite to a fitting portion so as to be fitted with the other side of the spring, and an O-ring fitted with the adjustment guide. In addition, the adjustment guide may have a shape tapered outward. The frame and the moving block have an adjustment module fitting hole into which the adjustment module is inserted to adjust the upper blade.
