The present invention relates to a taping apparatus for automatically bonding an insulating tape to both surfaces to which a cathode and a tab are bonded in manufacturing a lithium battery (Li-Battery).

In more detail, it is possible to cut the tapping tape by a certain length and to automatically adhere the tape to both sides of the cathode 7 by the tapping roller operated by the cylinder. Provide the device.

In order to manufacture a lithium battery (Li-Battery), as shown in FIG. 1, the insulating tape 1 is adhered to both surfaces of the connection surface of the cathode 7 and the tab 8, and the cathode 7 The rolls are rolled up to form an element.

The present invention seeks to provide an apparatus which is capable of automatically tapping the tape 1 on both sides of the connection surface of the cathode 7 and the tab 8 as described above.

However, conventionally, after cutting the tape 1 by the jig 2 as shown in FIG. 2, the cut tape was artificially attached as shown in FIG.

That is, the tape 1 is pulled out from the roll tape 1-1 and temporarily attached to the pedestal 3, and then the handle 6 of the operation plate 4 is operated to attach the operation plate 4 to the pedestal 3. By sticking, the tape 1 was cut by a certain length, and the cut tape 1 was attached as shown in FIG.

In this way, since the tape 1 is attached by an artificial method, not only the productivity is greatly reduced but also it is difficult to accurately tap and many insulation defects are generated.

The present invention provides an automatic tapping device that can solve the above problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic tapping apparatus which is capable of taking out the tape 1, cutting it uniformly, and tapping automatically.

Another object of the present invention is to provide an automatic tapping device which can eliminate the insulation defect by automatically tapping the tape in the correct position, and another object of the present invention is to improve the productivity and also to improve the function of the battery It is to provide an automatic tapping device.

In the above and other objects of the present invention, the timing belt 26 revolves between the timing pulleys 24 and 25 by means of rotation, and the fingers 27-1 and 28-1 are provided on the timing belt 26. Fixing the connection brackets (27) and (28) provided at the bisecting points, respectively, to draw the tape (1) on the guide shaft (30) by a predetermined length by the fingers (27-1) (28-1). And cam follower of shaft 17 fixed to operating arm 15 actuated by cylinder 13 by arranging cam 12 symmetrical to base 11 between timing pulleys 24 and 25. The actuating arm 15 is extended or narrowed when the 18 is moved along the cam 12 and the cam follower 18 is moved along the cam 12. It is achieved by the automatic tapping apparatus 10 provided with the cutter 31 and the rocket 31-1 in the lower side, and the sensor 32 and 32-1 in the upper side.

The above and other objects, features, and effects of the present invention will be more clearly understood by the following description based on the accompanying drawings.

4 and 5 are exemplary views showing an embodiment according to the present invention, for example, an embodiment of the automatic tapping apparatus 10.

The cam 12 is formed in the center of the base 11 in a '' shape, and the cam 12 is actuated with the hinge 14 by actuating the actuating arm 15 actuated by the cylinder 13. The shaft 17 is fixed to the middle portion of the c), and the cam follower 18 is inserted into the shaft 17, and the roller 16 is installed at the tip of the operating arm 15. Timing pulleys 24 and 25 are spaced in the first half of the cam 12 and the timing belt 26 is hung so that the timing belt 26 revolves, and the pulley 22 is attached to the timing pulley 24. Is installed in the mandrel is connected to the pulley and the belt 23 of the drive motor 20.

A pair of connecting brackets 27 provided with fingers 27-1 and 28-1 are fixed to the timing belt 26 inward in opposite directions.

The guide shaft 30 is fixed by the mounting brackets 29 and 29-1 on the center line of the timing belt 26, and the tape 1 wound on the reel 33 is finger 28 through the idle 34. -1) and the state held by the finger 27-1 in order. The cathode 7 which holds the cathode 7 is fixed to the leading part between the cams 12, and the cathode 7 is supported by the fixing lever 35 which is rotated by the rotary cylinder 36. Lose.

The operation relationship will be described below.

As shown in (a) of FIG. 5, the cathode 7 is settled in the holder 9 and operated with the tape 1 held on the fingers 27-1 and 28-1. .

As shown in the diagram (b) in which the cylinder 13 is operated, the cam pull 18 moves along the cam 12 as the rod is withdrawn and the operating arm 15 gradually narrows to perform tapping and finger simultaneously. The cutter 31 is operated to cut the tape 1 while the 28-1 grips the tape 1, and at the same time, the finger 27-1 performs the grip state as shown in (b). Release, the actuating arm 15 is further advanced to tap the tape 1 on both sides of the fixing part of the cathode 7 and the tab 8, and the cylinder 13 is reversed when the tapping is complete. The operation arm 15 is expanded because the operation arm 15 recovers the operation arm 15.

With the operating arm 15 retracted, the cathode 7 on which the tape 1 has been tapped, as shown in FIG. 1 by a separate operating device, has a suction head 40 as shown in (e). It is adsorbed by) and transported to a predetermined position.

When the driving motor 20 is operated while the new cathode 7 is placed on the holder 9, the pulleys 21 and 22 are rotated by the belt 23 and the timing pulleys are rotated by the rotation of the pulley 21. As the 24 and 25 are rotated, the timing belt 26 is rotated. The timing belt 26 is rotated ½ so that the finger 28-1 moves to the position of the lower finger 27-1, thereby transferring the tape 1 downward along the guide shaft 30 and the lower finger 27. -1 is moved to the position of the upper finger 28-1 to hold the tape 1.

As described above, the tapping is performed in the state where the tape 1 is transferred again.

The automatic tapping apparatus 10 of the present invention repeats the above process to attach the tape 1 to the cathode 7 on which the tab 8 is fixed.

As described above, according to the present invention, since both sides of the cathode and the tab fixing portion can automatically tap the tape, the tapping time can be shortened, so that the productivity can be greatly improved and the insulation failure can be prevented, thereby improving the performance of the electron. In addition, manufacturing costs can be greatly reduced.
