In general, a secondary battery refers to a battery that is used semi-permanently through charging, rather than being used once and thrown away.

Lithium ion batteries are most widely used in such secondary batteries. Since the lithium ion battery has many advantages compared to other batteries, it has recently been widely used as a battery for an electric vehicle as well as an electronic device such as a mobile phone or a notebook computer.

In such a lithium ion battery, positive and negative electrode active materials are coated on metal foil (Al or Cufoil) to manufacture positive and negative electrodes, and a separator is placed between the positive electrodes and wound to form a jelly roll (Jelly). Roll) and then inserted into a cylindrical or prismatic metal container, filled with electrolyte and sealed.

In this way, for the manufacture of the jelly roll, a material roll wound on a bobbin in the form of a roll of positive electrode, negative electrode, and separator is mounted on a spool, and the positive electrode, negative electrode, and separator are respectively transferred and supplied while being wound on the winding roll to make a jelly roll. When the material wound on the material roll of the positive electrode, the negative electrode, and the separator is all consumed, the operation of replacing the other material roll was required.

In particular, in the case of the separator, the roll diameter could not be increased due to the characteristics of the material, so it was necessary to frequently replace the roll in the winding process.

Accordingly, in the process of manufacturing jelly rolls of conventional lithium ion secondary batteries, frequent replacement of the material rolls and the operation of connecting the ends of the material rolls increase the stop time of manufacturing facilities, thereby increasing the productivity of lithium ion secondary batteries There was a problem of deterioration, a problem that safety accidents of workers frequently occur in the process of replacing a high-weight roll, and a problem of a decrease in manufacturing quality due to manual replacement.

Various technologies have been disclosed in order to solve the problems of the conventional manufacturing equipment, such that the standby material roll can be additionally mounted on only one spool, and the operator prepares the material by reading the material end of the replacement material roll to the mounting part, and prepares the automatic connection part Since the connecting tape is prepared on standby, so that the standby material roll is automatically connected to the used material roll when all the materials used are exhausted. Therefore, conventionally, two spools have to be used alternately to prepare, and workers are required to exchange materials, and manual work is required in the process of checking, managing, and replacing material consumption conditions, which reduces workability and productivity, and increases manufacturing costs. Of course, it still had several problems such as deterioration of manufacturing quality and occurrence of various safety accidents.

The interlocking gears 13a and 13a' installed on the shafts 13 and 13' are meshed, so that the upper and lower arms 12a and 12b move up and down around the interlocking shafts 13 and 13'. It opens to move the exchange material roll, or shrinks to restrict the movement of the exchange material roll.

In this way, the replacement material roll 3 is sequentially transferred from the rear of the transfer pipe 11 to the front, and is inserted into the moving spool 6 in front of the transfer pipe to be fixedly mounted.

In this way, the replacement material roll 3 supplied to the moving spool 6 has a bar code-printed closing tape 4 attached to the material end 3a, so peeling is required.

First, the bar code reader 29 installed on the upper part of the exchange material roll 3 detects the bar code of the closing tape 4, so that the material end 3a of the exchange material roll is located at 90 degrees to the right of the peeling means. Adjust the position by rotating the moving spool (6) so that it is located in the front.

In this state, as the moving table 21 is moved forward by the operating cylinder 22 of the material roll peeling means 20, the upper and lower tape separation ports 24 and 24' on the side of the moving table are removed from the replacement material roll. It is positioned so as to be in close contact with the upper and lower positions of the closing tape (4) attached to the material end (3a) of (3).

In this state, by rotating the replacement material roll 3 forward and reverse by the auxiliary spool 6, the upper and lower ends of the closing tape 4 are caught by the upper and lower tape separation ports 24 and 24'. to make it peel off.

In particular, since the upper and lower ends of the upper and lower tape separation ports 24 and 24' are formed with sharp pointed parts 24a and 24a', they are attached to the material end 3a of the replacement material roll 3, The closing tape 4 is more effectively peeled off and separated.

In this state, the ends of the upper and lower clamps 25 and 25' installed between the upper and lower tape separation ports clamp the material end 3a of the replacement material roll 3 .

This is the guide cam at the rear end of the upper and lower clamps 25 and 25' inserted into the cam guide grooves 27a and 27a' of the cam block while the cam block 27 is advanced by the cam cylinder 28. 25a) (25a') operates as a cam, and the rear ends of the upper and lower clamps open up and down around the rotation shaft 26 and the ends are constricted, thereby clamping the material ends 3a of the replacement material roll.

At this time, at the ends of the upper and lower clamps 25 and 25', elastic fitting holes 25c and 25c' of circular cross section are coupled to assembly grooves 25b and 25b', so that the elastic fitting holes are exchanged. The material end (3a) of the material roll for use is clamped while being pressed and pressed to prevent slipping.

In this state, while the moving table 21 is retracted and returned by the operating cylinder 22, the ends of the upper and lower clamps 25 and 25' hold the material ends 3a of the replacement material roll 3 It will be pulled and peeled off.

In this way, after peeling the material end 3a of the replacement material roll 3, a portion to which the closing tape is attached is cut and removed by the material roll cutting means 30.
