FIGS. 3 and 4 are a front view and a plan view showing the cathode sorting apparatus 20 according to the present invention.

Rotating means and fixing means are provided in each of the orbit grooves 4-1 of the index table 4. A magnet 26 is embedded in the inner surface of each guide groove 4-1 so that the lithium battery 1 can be fixed to the guide groove 4-1 and the bracket 25 is fixed to the bottom of the guide groove 4-1, The rotating shaft 21 having the magnet 23 embedded therein is fixed to the upper side of the interlocking shaft 21-1 and the interlocking roller 21 is fixed to the lower side of the interlocking shaft 21-1.

In particular, the magnet 23 of the rotary plate 22 is kept stronger than the magnet 26 of the index table 4.

The rotating plate 22 is made of a material such as soft abrasive water or rubber to prevent the lithium battery 1 from slipping and to prevent the interlocking roller 21 from slipping when it comes into contact with the driving roller 34 .

The above-described devices are mounted in the respective antenna grooves 4-1 of the index table 4, respectively.

As shown in FIG. 1, the following devices are mounted on the upper and lower sides of the position where the draw-in guide 8 is located.

The optical sensor heads 27 and 28 are provided on the upper side to detect when the cathode 3 of the lithium battery 1 rotated by the rotary plate 22 is aligned at a predetermined position, So that the operation of the motor 30 can be interrupted.

The origin slit plate 41 can be detected by the optical sensor 40 on the upper side of the stepping motor 30.

Hereinafter, the operation relationship will be described.

When the lithium battery 1 transported by the belt conveyor 7 is drawn into the recess 4-1 of the index table 4 through the lead guide 8, And is fixed by the magnet 26. As shown in Fig.

In this state, the stepping motor 30 is operated to rotate the timing pulley 31 slowly.

When the timing pulley 31 rotates continuously, the timing pulley 32 is rotated by the timing belt 33 so that the driving roller 34 also rotates together. When the magnet 23 of the rotating plate 22 rotates together with the index table 4, The lithium battery 1 is rotated.

When the driving roller 34 is rotated, the rotation plate 22 is rotated together with the interlocking roller 21 to rotate the lithium battery 1. When the lithium battery 1 is rotated, the photosensor head 27 (28) The stepping motor 30 is stopped when the cathode 3 is completely sensed by the optical sensor heads 27 and 28. The stepping motor 30 is stopped when the cathode 3 is completely sensed.

When the rotation is completed, the cylinder 43 is reversely operated and returned to the original state by the bracket 42, so that the driving roller 34 is brought into contact with the newly moved interlocking roller 21. [

After the driving roller 34 is connected to the interlocking roller 21, the above process is repeated.

On the other hand, the lithium battery 1 in which the cathode 3 is aligned can inspect the insulation state by the insulation resistance inspection apparatus 10 having a simple structure as shown in FIG. And the probe 46-1 is actuated by the finger cylinder 45 in addition to the probe 48 which is moved forward and backward by the cylinder 47 and the cathode 3 which is aligned by the probe 46-1 So that it can be inspected by the measuring device 49.
