Material roll cutting and installation setting device for replacement of secondary battery jelly roll manufacturing facility

The present invention relates to a material roll cutting and mounting setting device for replacement of a secondary battery jelly roll manufacturing facility, and more particularly, to a secondary battery jelly roll in a state in which the material end of a high-weight material roll is cut and gripped. It relates to a material roll cutting and mounting setting device for replacement of a secondary battery jelly roll manufacturing facility that automatically inserts and mounts into the main spool of the manufacturing facility and sets it.

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 A connecting tape is prepared on standby, so when the material used is exhausted, the standby material roll is automatically connected to the used material roll. Remove the bobbin of the used material roll and prepare a new material roll repeatedly as above. Therefore, conventionally, two spools have to be used alternately to prepare, and workers are required to exchange materials, as well as manual work is required in the process of checking, managing, and replacing material consumption, so workability and productivity are lowered, and manufacturing costs are high. Of course, it still had several problems such as deterioration of manufacturing quality and occurrence of various safety accidents.
