Description

Plate Cutter Assembly for Secondary Battery

The present invention relates to a pole plate cutter assembly for a secondary battery, and more particularly, the fine plate cutting quality is excellent without fine cutting of the pole plate for a secondary battery, and the replacement time is greatly shortened, which is very advantageous in terms of workability and the like. The present invention relates to a new electrode plate cutter assembly for secondary batteries, which can be set very quickly regardless of the conditions of the electrode plate, and thus is very preferable for installation work, and the life of the cutter can be extended even more because the edge of the cutter is not easily worn. .

Secondary batteries can be recharged after use, and can be repeatedly used in the same battery by reversely discharging to some extent, and thus, the secondary batteries have been widely used in various electronic devices such as mobile phones, notebook computers, and PDAs. As is well known, secondary batteries are generally made by stacking a negative electrode plate and a positive electrode plate in multiple layers with a separator interposed between a plurality of positive electrode plates having positive polarity and a plurality of negative electrode plates having negative polarity. That is, a plurality of positive electrode plates and negative electrode plates (hereinafter, referred to as the positive electrode plate and the negative electrode plate for the sake of understanding) are manufactured by interposing a separator between the positive electrode plate and the negative electrode plate to manufacture an electrode assembly having a predetermined area. The battery pouch in which the electrolyte is injected into the pouch through the opening of one side of the pouch is made, and the battery pouch of the secondary battery is charged and discharged, and then the one side opening of the battery pouch is sealed to complete the manufacture of the secondary battery. .

At this time, the pole plate is formed in a substantially rectangular plate shape, and on one side has a structure provided with electrode tabs, while unwinding the rail pole plate wound on the supply portion such as a supply bobbin (or roller) and transported for a long time to one side of the rail pole plate Since the electrode tabs are formed at regular intervals and the real electrode plate on which the electrode tabs are formed is cut at an appropriate position to make a rectangular plate-shaped pole plate, an apparatus for cutting the long rail electrode plate having such electrode tabs formed into a rectangular plate-type pole plate is essential. Is required.

An object of the present invention has a special structure that can accurately cut the pole plate precisely intersected in the right position without deformation, such as the position of the upper cutter and the lower cutter, the main part, so that fine cutting to the pole plate is not necessary The cutting quality is excellent, the replacement time is greatly reduced, and it is very advantageous in terms of workability, etc., and it is related to the conditions of the electrode plate unlike the conventional method, which requires a lot of setting time to cut the electrode plate (a difficult electrode plate) requiring high quality. It is possible to set it very quickly without any change, so it is very desirable in the efficiency of installation work, and for the new secondary battery which can prolong the life of the cutter because the edge of the cutter is not easily worn as compared to the conventional scissors type cutting device. It is to provide a pole plate cutter assembly.

The present invention includes a main bracket (16) disposed in the conveying line of the rail pole plate (4); An upper cutter 20 mounted on the main bracket 16; A lower cutter (30) mounted to the main bracket (16) and disposed at the same time in parallel with the lower side of the upper cutter (20) to allow the rail pole plate (4) to pass through the upper cutter (20); At least the upper cutter 20 is lifted from the upper cutter 20 and the lower cutter 30 to cut the predetermined position of the rail electrode plate 4 while the upper cutter 20 and the lower cutter 30 cross each other. And cutter operation unit for forming the individual pole plate (6); When the upper cutter 20 and the lower cutter 30 move forward relative to each other by the cutter operating unit to cut the rail electrode plate 4, the upper cutter 20 and the lower cutter 30 are placed in a fixed position. It provides a secondary battery pole plate cutter assembly, characterized in that it comprises a cutting guider to guide to be precisely intersected to make a precise cutting of the pole plate (6).

According to the present invention, two projections of the upper cutter and two projections of the lower cutter accurately position the upper cutter and the lower cutter when cutting the individual plate by the intersection of the upper cutter and the lower cutter by relatively advancing the upper cutter and the lower cutter. The upper and lower cutters can be pushed in the direction of the lower cutter to maintain a close contact between the upper cutter and the lower cutter by the pusher, and the close state of the upper cutter and the lower cutter can be maintained. By providing a more secure stopper (or stiffener), the cutter is deformed due to the cutting load when cutting the pole plate by the upper cutter and the lower cutter (for example, the upper cutter is pushed relative to the lower cutter Is a constitution to prevent a phenomenon, etc., and has the following effects.

First, since the upper plate and the lower cutter are intersected at precisely precise positions to cut the plate, the cutting plate can be precisely cut while maximizing the cutting quality.

Second, when the cutter is mounted, fine setting of the cutter portion is not necessary, so it is more efficient during installation work.

Third, the replacement time is greatly shortened, which is very advantageous in terms of overall workability.

Fourth, in the case of a demanding electrode plate, the conventional method takes about 8 hours to set the cutter, but the present invention can be set within 10 minutes regardless of the conditions of the electrode plate.

Fifth, there is a long life advantage compared to cutting the electrode plate by the conventional scissors method. Conventional scissors method has the disadvantage that the edge is easily worn because the blade is crossed, the present invention can have the effect of extending the life more because the edge (blade) is not easily worn.

Sixth, the stopper (or stiffener), which is the main part of the present invention, is designed in consideration of the case in which the cutting accuracy of the pole plate is lowered due to the cutting load generated during the pole plate cutting. As a result, it has the advantage of more reliably contributing to ensuring the cutting accuracy and cutting quality of the plate.

Seventh, when the upper and lower side grippers are disposed in the position facing each other, and the upper and lower cutters move forward to cut the rail plate, the upper and lower side grippers hold and support the rail plate so that the pole plate is stable. It can contribute even more to performing precise cutting work.

The pole plate cutter assembly for a secondary battery according to the embodiment of the present invention is disposed on the transfer line of the rail electrode plate 4 and at the same time, the upper cutter 20 and the lower cutter (arranged to be symmetrical to the top and bottom positions of the rail electrode plate 4). 30), the upper cutter 20 and the lower cutter 30 are cut by the cutter operation unit while cutting the rail pole plate 4 into the pole plate 6 in the form of a constant square plate, but by the cutting guider The cutter 20 and the lower cutter 30 are guided so as to precisely intersect in a precise position, so that the precise cutting of the electrode plate 6 is made.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, the real pole plate 4 having the electrode tab 6 formed between the upper cutter 20 and the lower cutter 30 constituting the pole plate cutting unit is transferred by a feeding unit or the like, which constitutes the pole plate cutting unit. By cutting the proper position of the rail electrode plate 4 by the relative cross-operation of the upper cutter 20 and the lower cutter 30 can be cut into a separate electrode plate 6 for the secondary electrode of the rectangular plate shape.

The pole cutting unit includes an upper cutter 20 and a lower cutter 30 which are lifted relative to the upper and lower positions of the rail pole plate 4, and at least an upper cutter 20 of the upper cutter 20 and the lower cutter 30. 20 is lowered in the direction of the lower cutter 30 while cutting the proper position of the rail pole plate 4 at the moment when the rail pole plate 4 is transported by the feeding unit (not shown) to form an individual pole plate 6. Can be configured. That is, the upper cutter 20 descends at the moment when the rail pole plate 4 is transported by the feeding unit, and the rail pole plate 4 is cut to cut the rail pole plate 4 to the individual pole plates 6 having a predetermined square area. You can cut one by one.

Specifically, a cutter bracket 10 is disposed on the transfer line of the rail plate 4, and the cutter bracket 10 has a block-shaped upper cutter support 22 and a lower cutter support by guide means such as an EL guide. The upper cutter 20 and the lower cutter 30 mounted on the upper cutter support 22 and the lower cutter support 32 are respectively orthogonal to the conveying direction of the rail electrode plate 4. While arranged in the vertical position facing each other. The upper cutter 20 is arrange | positioned at the upper surface position of the rail electrode plate 4, and the lower cutter 30 is arrange | positioned at the bottom surface position of the rail electrode plate 4. As shown in FIG.

In the present invention, the cutter lift operation device is connected to the motor 42 mounted on the cutter bracket 10 and the motor shaft of the motor 42, and at the same time the ball screw nut on the proximal end of the upper cutter support 22. It may include a ball screw coupled through the media. In the case of the present invention, the motor 42 is composed of an upper motor 42A and a lower motor 42B mounted on the cutter bracket 10, and the upper motor 42A and the lower motor 42B are arranged in a line up and down. Is placed. In addition, an upper ball screw is axially coupled to the motor shaft of the upper motor 42A, and the upper ball screw is coupled to the upper cutter support 22 via a ball screw nut, and also to the motor shaft of the lower motor 42B. The lower ball screw is axially coupled, and the lower ball screw is also coupled to the lower cutter support 32 via the ball screw nut.

Therefore, the upper motor 42A and the lower motor 42B are synchronized with each other when the rail electrode plate 4 is inserted between the upper cutter 20 and the lower cutter 30 so that the upper cutter 20 and the lower cutter 30 operate. Since the relative approach in the direction facing each other at the same time, by the two upper cutter 20 and the lower cutter 30 can be configured such that the rail plate 4 is cut into individual plate 6 of the rectangular plate shape.

In the present invention, the rail pole plate 4 is supplied onto the pole plate support panel 12 disposed horizontally at the front position and the rear position of the upper cutter 20 and the lower cutter 30, and the rail pole plate 4 is stopped. The upper cutter 20 and the lower cutter 30 to move forward in the direction facing each other (that is, the upper cutter 20 is lowered and the lower cutter 30 is moved upward) of the upper cutter 20 An embodiment is shown in which the blades 24a and the blades 34a of the lower cutter 30 intersect and cut a defined point in the rail electrode plate 4 to form the individual electrode plates 6. At this time, the pole plate support panel 12 is fixed to the cutter bracket 10 via a bracket and a fastener.

Of course, without the lower motor 42B and the lower ball screw, the lower cutter 30 is fixed to the cutter bracket 10, and only the upper cutter 20 is lowered by the driving of the upper motor 42A as described above. The rail plate 4 may be configured to be cut into individual pole plates 6 while being lifted relative to the cutter 30.

On the other hand, the apparatus for causing the upper cutter 20 and the lower cutter 30 to move forward and backward relative to each other may be composed of an upper cylinder and a lower cylinder in addition to the upper motor 42A and the lower motor 42B. That is, the cylinder rod of the upper cylinder is connected to the upper cutter support 22, the cylinder rod of the lower cylinder is configured to be connected to the lower cutter support 32, the upper cutter 20 by the operation of the upper cylinder and the lower cylinder And the lower cutter 30 may be relatively moved forward and backward so that the rail electrode plate 4 is cut into the individual electrode plates 6. Even when the two upper cutters 20 and the lower cutters 30 are configured to be relatively moved forward and backward by such a cylinder, only the upper cylinder is connected to the upper cutter support 22 so that only the upper cutters 20 are lower cutters 30. It may also be possible to lower the direction so that the rail electrode plate 4 is formed into individual electrode plates 6.

At this time, the present invention, as described above, the upper cutter 20 and the lower cutter 30 can accurately cut the pole plate 6 by precisely intersecting at the correct position, and fine cutting for the pole plate 6 is not necessary. It is also characterized by excellent cutting quality.

It is possible to make excellent cutting quality without the need for fine cutting of the pole plate (6) is a cutting guider for guiding the upper cutter 20 and the lower cutter 30 to precisely cross relatively precisely in place. It is because it has a structure provided.

That is, the upper cutter 20 is formed in a flat shape having a pair of protrusions 26 extending in a vertical direction on a plate-shaped cutter body 24 having a sharp blade-shaped blade 24a at a lower end thereof. The lower cutter 30 is also formed in the shape of a depressor having a pair of protrusions 36 extending in the vertical direction on a plate-shaped cutter body 34 having a sharp blade 34a at the lower end thereof. The upper cutter 20 is placed upright so that the blades 24a of the cutter body 24 and the pair of protrusions 26 face downward, and the lower cutter 30 is connected to the blades 34a of the cutter body 34. The pair of protrusions 36 are placed upright to face upward.

Therefore, when the upper cutter 20 and the lower cutter 30 are moved forward by the cutter operating unit, the pair of projections 26 of the upper cutter 20 and the pair of projections of the lower cutter 30 ( The guides (exactly, the blades 24a of the upper cutter 20 and the lower cutter 30 of the upper cutter 20) intersect the inner surfaces 36 and slide relative to each other while the upper cutter 20 and the lower cutter 30 intersect at the correct positions. Since the blade 34a is guided so as to intersect in the correct position, it is possible to precisely cut the rail electrode plate 4 passed between the upper cutter 20 and the lower cutter 30, thereby fine cutting the electrode plate 6. It is possible to make excellent cutting quality without the need for this.

Since the lower cutter 30 is a reference when cutting, the lower cutter 30 is firmly fixed to the lower cutter support 32 through a fastener such as a bolt, and the upper cutter 20 is disposed at an inner side facing the lower cutter 30. The lower cutter 30 is provided with a pinhole 24h connected to the opposite outer surface (with the cutter body 24) and the pinhole 24h is caught by the hook pin 24p provided on the upper cutter support 22. ) Has a structure mounted so as to be able to move forward and backward in the inner surface direction, and at the same time, the upper cutter 20 has an inner surface on the inner surface of the lower cutter 30 by means of close contact with the lower cutter 30. It is configured to precisely cut the rail electrode plate 4 while crossing the lower cutter 30 in a close state.

At this time, the close means is a pusher 28 is slidably coupled to the pusher hole provided in the upper cutter support 22, the pusher 28 is interposed between the pusher hole of the pusher 28 and the upper cutter support 22 ( 28 may include an elastic body for pushing the upper cutter 20 toward the lower cutter 30 to be in close contact with the lower cutter 30. The upper cutter supporter 22 includes a pusher hole directed toward the outer surface of the upper cutter 20, a pusher hole includes an elastic body such as a spring, and the pusher 28 is coupled to the pusher hole so as to be moved forward and backward, and the elastic body The pusher 28 is elastically pushed by the pusher 28, and the pusher 28 pushes the upper cutter 20 toward the lower cutter 30 by the force of the elastic body, so that the inner side of the upper cutter 20 lowers the lower cutter. In close contact with the inner surface of the 30, the upper electrode 20 and the lower cutter 30 may be precisely intersected to precisely cut the rail electrode plate 4. The function of the pusher 28 is a force generated by the elastic body at the intersection of the upper cutter 20 and the lower cutter 30 is generated to push the projection portion 26 of the upper cutter 20 with a constant force to the upper cutter Since 20 and the lower cutter 30 are to be in close contact with each other precisely, it can be said to contribute more to the precise cutting of the electrode plate (6).

On the other hand, the pusher 28 is formed on the outer circumferential surface is formed with a flange-shaped locking projection further protruding radially outward, the support jaw further protruding in the central direction on the inner circumferential surface of the pinhole 24h of the upper cutter support 22, It is preferable to have a structure which prevents the pusher 28 from being detached from the pinhole 24h of the upper cutter support 22 by engaging the catching jaw of the pusher 28 with the supporting jaw of the inner circumferential surface of the pinhole 24h. The upper cutter support 22 is provided with a pair of side-by-side pusher support pieces 22a extending downward, and a plurality of pinholes 24h are formed in the pusher support pieces 22a in the vertical direction, and the upper cutter ( By pushing the outer surface of the 20 to a plurality of rows and a plurality of rows of pushers 28 in a balanced manner, it is possible to increase the closeness of the upper cutter 20 and the lower cutter 30 to a higher degree. Increasing the adhesion accuracy of the lower cutter 30 can be more contributing to the precise cutting of the pole plate (6) is made.

In addition, in the present invention, the surface to which the lower cutter 30 is attached (that is, the inner surface of the lower cutter 30) may include a spacer 52 that is precisely processed to ensure flatness. That is, the lower cutter support 32 for supporting the lower cutter 30 is provided with a spacer 52 which is precisely processed, and the lower cutter 30 is in close contact with the spacer 52. In the state in which the inner surface of the cutter 30 is in close contact), the lower cutter support 32 may be fixed via a fastener. A tab hole for fixing the lower cutter 30 is formed in the spacer 52, and a hole communicating from the inner side to the outer side is formed in the lower cutter 30 so as to correspond to the tap hole, and is coupled to the hole of the lower cutter 30. When the fasteners, such as bolts, are fastened to the tab holes for fixing the lower cutter 30 formed in the spacer 52, the lower cutter 30 is stably mounted to the spacer 52 to improve the flatness of the lower cutter 30. Since it is possible to ensure, it is possible to maintain an even flatness of the lower cutter 30 when cutting the rail electrode plate 4 by the intersection of the upper cutter 20 and the lower cutter 30, and thus the lower cutter 30 A structure that ensures even flatness of can also contribute more precisely to the cutting plate 6 and to improve the cutting quality.

In addition, the upper cutter supporter 22 further includes a stopper 62 having a tip portion in contact with an outer surface of the upper cutter 20, and the upper cutter 20 and the lower cutter 30 intersect each other, and thus the rail electrode plate 4. ), The stopper 62 prevents the upper cutter 20 from being deformed due to the cutting load, thereby precisely cutting the rail electrode plate 4 while the upper cutter 20 is in close contact with the lower cutter 30. Can be cut. At this time, the upper cutter support 22 is formed side by side a plurality of holes penetrated to the front and rear surfaces, the stopper support block 64 is fixed to the rear position of the upper cutter support 22 by fasteners such as bolts. The stopper support block 64 is formed with a stopper coupling hole 64h communicated with the front and rear surfaces, and the stopper coupling hole 64h has an incision 64a communicated with the lower end of the stopper support block 64. It is provided, on the lower side of the stopper support block 64 on the basis of this incision (64a) is provided with two fastening pieces (64b), fastening orthogonal to the incision (64a) in these two fastening pieces (64b) A ball is formed so that the pin-shaped stopper 62 is fitted into the stopper engaging hole 64h of the stopper support block 64 and is inserted into the hole communicating with the front cutter support 22 in the front and rear surfaces, thereby stopping the stopper. The tip of 62 has an outer surface (ie, an upper surface) of the upper cutter 20. The upper cutter 20 is supported while being in contact with a surface opposite to the inner surface facing the inner surface of the lower cutter 30 among the inner and outer surfaces of the lower cutter 20. At this time, in the state in which the pin-shaped stopper 62 is inserted into the stopper coupling hole 64h of the stopper support block 64, a bolt is provided in the fastening hole formed at the two fastening pieces 64b at the lower side of the stopper support block 64. Tightening the fasteners, etc., the two fastening pieces (64b) close to each other and narrows the diameter of the stopper coupling holes (64h) formed on the fastening pieces (64b), and is fitted into the stopper coupling holes (64h) The pin shaped stopper 62 can be firmly held in place.

On the other hand, the stopper 62 may be fixed in various ways in addition to the above-described method. That is, the stopper 62 is fixed using a fixing nut, and a tap hole (screw hole) is made in the side of the stopper support block 42 to press-fix the stopper 62 with a bolt that is coupled to the tap hole. Various methods can be employed, such as the method.

Therefore, when the stopper 62 cuts the electrode plate 6 by the intersection of the upper cutter 20 and the lower cutter 30, the upper cutter 20 (top) is pushed backward by the cutting load so that the cutter 62 is cut well. Since it prevents the phenomenon, it can help to ensure the precise cutting work and the cutting quality of the electrode plate (6). That is, even when the upper cutter 20 (top) and the lower cutter 30 (bottom) are brought into close contact with the pusher 28 in the standby state, the upper cutter 20 is cut by the cutting load when the pole plate 6 is cut. ) May be pushed to the rear (ie, away from the lower cutter 30), and thus cutting may not be performed properly. The stopper 62 firmly supports the upper cutter 20 at the outer side position, so that the pole plate (6) Since the stopper 62 prevents this phenomenon even when the upper cutter 20 tries to push backward due to the cutting load during cutting, the phenomenon in which the cutting of the pole plate 6 is not properly performed can be reliably prevented. . That is, it can be said that the stopper 62 has a support function for maintaining the state in which the upper cutter 20 and the lower cutter 30 are in close contact with each other when the pole plate 6 is cut.

15 and 16 show another embodiment of the present invention. According to another embodiment of the present invention shown in FIGS. 15 and 16, instead of the stopper 62, a stiffener 72 is employed. The stiffener 72 prevents the deformation of the cutter (exactly, the bending of the upper cutter 20) generated during the cutting load.

The stiffener 72 is formed in a block shape having a predetermined length and area, the surface facing the front or rear of the upper cutter 20 (preferably the front of the upper cutter 20) is composed of an even flat surface. A plurality of fastening holes are formed in the flat surface of the stiffener 72, and the upper cutter 20 is formed such that a plurality of holes corresponding to the plurality of fastening holes of the stiffener penetrates from the inner side to the outer side, When the fasteners coupled to the holes of the upper cutter 20 are tightened to the fastening holes formed in the flat surface of the stiffener 72, the stiffeners 72 can be fixed to the inner side or the outer side of the upper cutter 20. . In the present invention is shown an embodiment in which the stiffener 72 is mounted on the inner surface of the upper cutter 20 (ie, the surface facing the inner surface of the lower cutter 30).

Therefore, the lower cutter 30 is firmly fixed to the lower cutter support 32 through a fastener or the like, and there is no fear of deformation, and the upper cutter 20 is equipped with the stiffener 72 so that the upper cutter (20) Also, since there is no fear of deformation due to the cutting load during the cutting work of the pole plate 6, the deformation of the cutter portion is prevented, and as a result, the precision cutting work of the pole plate 6 is possible and the effect of improving the cutting quality can be expected. have.

On the other hand, according to the present invention, when the rail electrode plate 4 is cut by the upper upper cutter 20 and the lower cutter 30 on the upper cutter 20 side and the lower cutter 30 side, the rail electrode plate 4 is cut. A gripper 82 for holding is further provided.

An upper gripper support block is provided on the upper cutter support 22, and an upper gripper 82A is mounted on the upper gripper support block, and the lower cutter support 32 has a lower gripper support block facing the upper gripper support block. The lower gripper support block is provided with a lower gripper 82B, and the upper gripper 82A and the lower gripper 82B are disposed at positions facing each other, and then the upper cutter 20 and the lower cutter are disposed. Since the upper gripper 82A and the lower gripper 82B hold and hold the rail pole plate 4 when the 30 moves forward to cut the rail pole plate 4, the stable and precise cutting of the pole plate 6 is performed. While it may contribute to this, the electrode plate 6 cut and separated from the rail electrode plate 4 is transferred to the required position.

Meanwhile, the upper plate 20 and the lower cutter 30, which were advanced at the time of transporting the pole plate 6 after being caught and transported by the two grippers 82, were transferred to the pole plate 6 cut from the rail plate 4. The gripper 82 is returned (returned) to its original position.

At this time, the upper cutter 20 and the lower cutter 30 and the gripper 82, the upper cutter 20 support and the lower cutter 30 support are configured to be advanced and returned by the transfer return means.

In the present invention, the upper cutter 20, the lower cutter 30, the upper cutter 20 support, the lower cutter 30 support, the upper and lower side gripper 82, the cutter lifting unit portion are all supported by the cutter bracket 10 The cutter bracket 10 equipped with the main part is mounted on the main bracket 16 extending along the rail plate 4 conveying line such that the cutter bracket 10 can be moved back and forth by a guide means such as an L guide. Forward and backward operation of 10 can be made by the transfer operation unit. In the present invention, the ball screw 19 is mounted on the main bracket 16 so as to be rotatable on the screw support, and the drive motor 18 is connected to the ball screw 19 so that the motor shaft can be powered. The ball screw nut is coupled to the ball screw 19 is connected to the cutter bracket 10, so that when the motor shaft of the drive motor 18 rotates in one direction, the two grippers 82 are separated by the two grippers 82. The main part and the pole plate 6 are transferred together in the state of holding the pole plate 6, and after the pole plate 6 is transferred, the motor shaft of the driving motor 18 rotates in the opposite direction to the cutter bracket 10. And the main part and the two grippers 82 are returned (returned) to their original positions. Of course, the motor shafts of the two motors 42A and 48B operated to hold the pole plates 6 with the two upper grippers 82 by relatively advancing the two upper cutters 20 and the lower cutters 30 are the upper cutters. The upper cutter 20, the lower cutter 30, and the two grippers 82 are returned to their original positions (ie, the upper portion) by rotating in the opposite direction to the direction in which the portion 20 and the lower cutter 30 rotate relative to each other. The cutter 20 and the gripper 82 of the upper side are raised again, and the lower cutter 30 and the gripper 82 of the lower side are lowered again. That is, after the individual pole plates 6 are caught and transported by the two grippers 82, the cutter bracket 10 and the main part are returned to their original positions, and the upper cutter 20, the upper cutter support 22, and the upper part are returned to their original positions. The operation of returning the side gripper 82, the lower cutter 30, the lower cutter support 32, and the lower side gripper 82 back to the original position is synchronized.

In summary, the structure and the effects of the main part of the present invention, the upper cutter 20 and the lower cutter 30 in the relative advance and the cross between the upper cutter 20 and the lower cutter 30 at the rail electrode plate 4 When cutting the individual pole plates 6, two protrusions 26 of the upper cutter 20 and two protrusions 36 of the lower cutter 30 accurately position the upper cutter 20 and the lower cutter 30. Since it is guided so as to intersect, there is an effect that can ensure a good cutting quality while precise cutting of the electrode plate (6) can be made.
