1. An automatic replacement device of a secondary battery material, the device comprising:
a first supply reel and a second supply reel;
reel support parts, each of the reel support parts including a reel rotation shaft onto which the first and second supply reels are insertable and each of which is configured to support the first and second supply reels around which the secondary battery material is windable and from which the secondary battery material can be unwound;
a material support part spaced apart from the reel support parts and configured to support the secondary battery material as the secondary battery material is unwound from one of the first and second supply reels;
clamping parts, the clamping parts being configured to be movable independently from the material support part and each including:
a clamping roller spaced apart from the reel support parts and configured to come into contact with the secondary battery material when replacing the first and second supply reels,
a vacuum suction part adjacent to the clamping roller and configured to suction the secondary battery material by vacuum,
a clamping frame configured to rotatably support the clamping roller and to support the vacuum suction part, and
a cutter coupled to one side of the clamping frame and configured to cut the secondary battery material when coming into contact with the secondary battery material;
first drive parts spaced apart from the clamping parts and configured to move the clamping roller toward and away from the secondary battery material;
second drive parts between the clamping parts and the first drive parts and configured to move the cutter toward and away from the secondary battery material; and
a frame part,
wherein the reel support parts, the clamping parts, the first drive parts, and the second drive parts are each provided as a pair that are arranged symmetrically to each other,
wherein the frame part is directly coupled to and supports each of the pair of clamping parts, the pair of first drive parts, and the pair of second drive parts,
wherein the automatic replacement device is configured to cut a first web of secondary battery material wound around the first supply wheel as the first web of secondary battery material is suctioned to the vacuum suction part after being adhered to a second web of secondary battery material wound around the second supply reel when the first supply reel is replaced, and
wherein the automatic replacement device is configured to replace the secondary battery material without a stop in an operation of the automatic replacement device.
