Abstract

An automatic replacement device of a secondary battery material including reel support parts to support a supply reel; a material support part spaced apart from the reel support part; clamping parts, each including a clamping roller to come into contact with the material when replacing the supply reel, a vacuum suction part to suction the material by vacuum, a clamping frame to rotatably support the clamping roller and the vacuum suction part, and a cutter to cut the material when coming into contact with the material; first drive parts to move the clamping roller toward/away from the material; and second drive parts to move the cutter toward/away from the material, wherein the automatic replacement device cuts the material as the material is suctioned to the vacuum suction part after being adhered to a material wound around a replacement supply reel when the supply reel is replaced.

First claim

What is claimed is:

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.

2. The automatic replacement device as claimed in claim 1 , wherein the reel support parts each include:
a reel frame configured to rotatably support the reel rotation shaft.

3. The automatic replacement device as claimed in claim 1 , wherein the material support part includes:
a first roller adjacent to one of the first and second supply reels and configured to come into contact with and support one surface of the secondary battery material;
a second roller spaced apart from the first roller and configured to come into contact with and support the other surface of the secondary battery material; and
a third roller spaced apart from the second roller and configured to come into contact with and support the one surface of the secondary battery material.

4. The automatic replacement device as claimed in claim 3 , wherein the material support part further includes:
a fourth roller adjacent to the second supply reel and configured to come into contact with and support the one surface of the secondary battery material wound around the second supply reel; and
a fifth roller spaced apart from the fourth roller and adjacent to the second roller and configured to come into contact with and support the other surface of the secondary battery material wound around the second supply reel.

5. The automatic replacement device as claimed in claim 1 , wherein:
the first drive parts each include:
a first cylinder configured to provide a hydraulic pressure or a pneumatic pressure; and
a first cylinder rod inserted into the first cylinder and configured to linearly move in a lengthwise direction of the first cylinder, and
the first cylinder rod is connected to a lower side of the clamping frame and is configured to move the lower side of the clamping frame forward toward the secondary battery material or rearward so as to be spaced apart from the secondary battery material.

6. The automatic replacement device as claimed in claim 1 , wherein:
the second drive parts each include:
a second cylinder configured to provide a hydraulic pressure or a pneumatic pressure;
a second cylinder rod inserted into the second cylinder and configured to linearly move in a lengthwise direction of the second cylinder; and
a cylinder frame connected to one side of the clamping frame, and

the second cylinder rod is configured to move the cylinder frame forward toward the secondary battery material or rearward so as to be spaced apart from the secondary battery material.

7. The automatic replacement device as claimed in claim 6 , wherein when the cylinder frame is moved forward, the cutter comes into contact with the secondary battery material and cuts the secondary battery material.

8. The automatic replacement device as claimed in claim 4 , wherein the frame part further includes:
a pair of main frames installed facing each other and configured to rotatably support the second roller and the fifth roller; and
a sub frame installed across the pair of main frames between the main frames.

9. The automatic replacement device as claimed in claim 8 , wherein the sub frame further includes:
a through part on one side to pass through the sub frame in a lengthwise direction of the sub frame and through which the cutter passes;
a suction tube installed inside the sub frame in the lengthwise direction; and
a plurality of suction parts in communication with the suction tube and configured to suction foreign substances.
