And the first punch 230a is formed to have a cross section corresponding to the first pocket 124a so as to be able to enter and exit the first pocket 124a, and similarly, the second punch 230b is It is formed to have a cross section corresponding to the second pocket 124b so that it can enter and exit the inside and outside of (124b).

Here, the first punch 230a processes (punches) the top line side of the electrode plate E together with the first die 130a as described above, and the second punch 230b Together, the bottom line side of the electrode plate E is processed (punched).

On the other hand, the upper mold 200 has the first and second punches 230a and 230b and the scrap to prevent the scrap S from rising along the first and second punches 230a and 230b when the electrode plate E is processed (punched). First and second air inlet passages 240a and 240b are formed to guide the inflow of external air between (S).

For example, when the first and second punches 230a and 230b are mounted on the lower surface of the punch plate 220, the first and second air introduction passages 240a and 240b are punched at one side of the punch holder 210. It is formed to pass through the inside of the holder 210 and the punch plate 220 vertically through the first and second punches 230a and 230b, respectively.

For example, when the first and second punches 230a and 230b are mounted on the lower surface of the punch holder 210, the first and second air introduction passages 240a and 240b are punched at one side of the punch holder 210. Through the inside of the holder 210, the first and second punches 230a and 230b are vertically penetrated.

Air is introduced from the outside of the notching mold according to the present invention into the first and second air inlet passages 240a and 240b thus formed, and the air introduced through the first and second air inlet passages 240a and 240b is respectively It is injected to the outside of the lower surfaces of the first and second punches 230a and 230b, whereby the first punch 230a and scrap S and the second punch 230b and scrap during processing (punching) of the electrode E While the vacuum force generated between (S) is lost, the scrap (S) falls away from the first and second punches 230a and 230b and into the first and second pockets 124a and 124b.

Here, a known technique for introducing air through the first and second air introduction passages 240a and 240b and injecting the introduced air to the outside of the lower surfaces of the first and second punches 230a and 230b. Therefore, a detailed description thereof is omitted.

As a result, the scrap S is prevented from rising.

Here, when one end of the fingers 310 pushes the scrap S down to the lower side of the first pocket 124a, the other ends of the fingers 310 do not interfere with the transfer of the electrode plate E, so that the first pocket ( 124a) is rotated to the upper side.

The second scrap rising preventing means 400 includes an adsorption plate 410 that pivots up and down inside the second pocket 124b, and an adsorption plate that operates the adsorption plate 410 in an up and down direction during processing of the electrode plate E. A servomotor 420 is included.

When the rotational movement is performed, the vacuum pressure applied to the vacuum adsorption holes 414 is broken and the scrap S is put down, whereby the scrap S generated inside the second pocket 124b is prevented from rising.

Here, since applying vacuum pressure to the vacuum adsorption holes 414 or breaking the vacuum pressure applied to the vacuum adsorption holes 414 is a known technique, a detailed description thereof will be omitted.

As shown, the suction plate servomotor 420 is installed at the rear end of the suction plate frame 412 to be spaced apart from the suction plate 410, and the suction plate servomotor 420 installed in this way uses a conventional belt and belt pulley. The adsorption plate 410 is connected to the adsorption plate support shaft 416 which pivotably supports the adsorption plate 410 in the vertical direction at the front end side of the adsorption plate frame 412 as a medium.
