Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cable type secondary battery manufacturing apparatus,

The present invention relates to an apparatus for manufacturing a cable-type secondary battery.

Recently, a secondary cell is a device that converts external electrical energy into a form of chemical energy, stores it, and produces electricity when needed. The term "rechargeable battery" also means that the battery can be recharged several times. Common secondary batteries include lead acid batteries, NiCd batteries, NiMH batteries, Li-ion batteries, and Li-ion polymer batteries. Secondary batteries provide both economic and environmental advantages over single-use primary batteries.

Secondary cells are currently used for low power applications. Such as a device that assists the starting of a vehicle, a portable device, a tool, and an uninterruptible power supply. Background Art [0002] Recent developments in wireless communication technology have led to the popularization of portable devices and the tendency to wirelessize many types of conventional devices, and demand for secondary batteries is exploding. In addition, hybrid vehicles and electric vehicles are being put to practical use in terms of prevention of environmental pollution, and these next generation vehicles employ secondary battery technology to reduce the value and weight and increase the life span.

Generally, a secondary battery is a cylindrical, square, or pouch type battery. This is because the secondary battery is manufactured by inserting an electrode assembly composed of a cathode, an anode, and a separator into a pouch-shaped case of a cylindrical or rectangular metal can or an aluminum laminate sheet, and injecting an electrolyte into the electrode assembly. Therefore, since a certain space for mounting the secondary battery is indispensably required, there is a problem that the cylindrical shape, the square shape, or the pouch shape of the secondary battery acts as a constraint on the development of various types of portable devices. Therefore, there is a demand for a new type secondary battery which is easy to deform in shape.

On the other hand, according to this demand, a linear battery, which is a battery having a very large ratio of length to cross-sectional diameter, has been developed and discloses a variable-type battery comprising an inner electrode, an outer electrode and an electrolyte layer interposed between these electrodes. Such a secondary battery is characterized by having a so-called cable structure which is formed in an elongated shape and can be expanded and contracted in the longitudinal direction.

However, such a cable-type secondary battery includes a process of removing the core after winding it on a core in order to manufacture a negative electrode in the manufacturing process. In this core removal process, by the interfacial friction between the core and the cathode There is a problem that a part of the negative electrode is exposed to the outside and a dropout occurs.

Accordingly, there is a high need for a cable-type secondary battery that can solve the problem that occurs in the process of removing the core after winding the negative electrode while using the conventional cable-type secondary battery.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and the technical problems required from the past.

Specifically, it is an object of the present invention to provide a negative electrode having a hollow structure in which a negative electrode is wound in a process of manufacturing a negative electrode, Type secondary battery.

According to an aspect of the present invention, there is provided an apparatus for manufacturing a cable-

An apparatus for manufacturing a cable-type battery cell in which a cathode, a separator, and an anode are sequentially wound on an outer surface of a winding core,

A core supply unit for supplying the core while advancing the core in a first direction;

A negative electrode supply part for winding while supplying a wire-shaped negative electrode in a spiral shape to an outer surface of a winding core supplied in a first direction from a winding core supply part;

A separation membrane supply unit for supplying a strip-shaped separation membrane while spirally winding the separation membrane on the outer surface of the negative electrode wound on the winding core; And

A positive electrode supplying unit for supplying a strip-shaped positive electrode wound on the outer surface of the separator wound on the winding while spirally winding;

. ≪ / RTI >

According to the present invention, the winding can be preferably applied with a wire of an electrically insulating material, for example, the wire can be made of a hollow structure. Therefore, since it is not necessary to remove the crimp after winding the negative electrode, it is possible to prevent the detachment of the tongue caused by the crimp removing process, thereby securing safety in the manufacturing process.

The wire may be polygonal, circular or elliptical in shape in vertical section, but is not limited thereto.

In one specific example, the crimp may be of a structure supplied at a rate of 0.5 to 2 mm / sec.

The core feeder may be, for example, a structure that feeds the core in a first direction in a rotating or non-rotating state.

In the above structure,

A rotating circular plate having a through hole through which the winding core passes and which rotates clockwise or counterclockwise with respect to the first direction; And

One or more cathode feeding rollers mounted on one surface of the rotary disk with the roller axis parallel to the first direction and supplying a cathode;

As shown in FIG.

In one specific example, the cathode feeding roller may be a structure that supplies the cathode while rotating in a direction opposite to the rotation direction of the rotary disk. In some cases, a feeding roller or a tension controller can be additionally provided so that the negative electrode can be effectively wound without a gap while maintaining a constant tension with respect to the winding core.

The rotary disk may have a structure in which a plurality of cathode feeding rollers are positioned radially with respect to a through hole. That is, since the cathode feeding rollers are spaced apart from each other at equal intervals, the cathodes supplied from each cathode feeding roller can be stably wound without any deviation.

In some cases, the rotary disk may have a structure in which one or more induction members for guiding uniformly the negative electrode wound from the respective negative electrode feeding rollers to the outer surface of the winding core are mounted. The guide member is provided to easily guide the cathode, and may be provided in various shapes such as a guide bar shape or a roller shape.

Here, according to the present invention, the four cathode feeding rollers may be arranged radially with respect to the through hole, but the position and the number of the cathode feeding rollers are not particularly limited. Therefore, the cathode can be stably wound on the winding core by uniformly supplying the cathode at the same speed while the cathode feeding rollers are fixed at the stable position.

In one specific example, the separation membrane winding direction of the separation membrane supply part and the anode winding direction of the anode supply part are equal to each other and can be reversed with respect to the anode winding direction of the cathode supply part.

In the above structure, the separation membrane supplying unit and the anode supplying unit may be structured so as to be mutually interlocked so as to be opposite to the cathode winding direction of the cathode supplying unit.

Therefore, the winding directions of the separation membrane supplying unit and the anode supplying unit are opposite to each other with respect to the cathode supplying unit, so that the cathode is wound at a predetermined angular velocity, and warping or twisting due to rotational force applied to the winding core can be minimized.

According to another aspect of the present invention,

A separation membrane feeding roller for supplying a separation membrane; And

A separation membrane rotation shaft mounted on one end of the shaft of the separation membrane feeding roller and rotating counterclockwise or clockwise with respect to the first direction;

. ≪ / RTI >

The axis of the separation membrane feeding roller may be a pivot structure mounted on the separation membrane rotation axis so as to adjust the screw-type wedging angle of the separation membrane with respect to the winding core.

In addition, the anode-

A positive electrode feeding roller for supplying an anode; And

A positive electrode rotation axis in which the shaft of the positive electrode feeding roller is mounted at one end and is rotated counterclockwise or clockwise with respect to the first direction;

. ≪ / RTI >

The axis of the positive electrode feeding roller may be pivotally mounted on the anode rotation axis so as to adjust the screw-type wedging angle of the anode with respect to the winding core.

In the above structure, the separation membrane rotation axis and the anode rotation axis may be structured such that the other ends of the separation membrane rotation axis and the anode rotation axis are connected to each other so that they can rotate relative to each other around the winding core.

In one specific example, the axis of the separation membrane feeding roller and the axis of the anode feeding roller may each independently be a structure in which a screw threading angle is set within a range of 20 to 80 degrees with respect to the winding.

According to the present invention, the cathode supply part may be structured to rotate at a speed of, for example, 100 to 500 rpm, and the separation membrane supply part and the anode supply part may be rotated at a speed of 30 to 70 rpm. That is, the separation membrane supplying unit and the anode supplying unit interlock with each other to rotate in the opposite direction to cancel the rotational force of the cathode so as to reduce the rotational force of the cathode wound at a relatively high rotational speed.

In some cases, a holder for stabilizing the winding state of the negative electrode wound on the outer surface of the winding core and inducing the winding of the winding can be additionally provided between the negative electrode supplying portion and the separation membrane supplying portion.

The structure may further include a cell winder for winding up the battery cell in which the anode is finally wound. Here, a holder may be additionally provided between the anode supply part and the cell winder, and the winding can be stably moved in cooperation with the holder positioned between the cathode supply part and the separation membrane supply part.

In some cases, the anode may further include a cutting portion for cutting the finally-wound battery cell to a predetermined length. In the present invention, the cell wider takes the structure of winding the battery cell, and if necessary, it may be a structure in which a separate cutting portion is formed and cut to a predetermined length and recovered.
