Description

[Technical field]

[0001] The present invention relates to a cutting system for an electrode plate notching device and a method for setting an electrode plate cutter, and more particularly to a cutting system for an electrode plate notching device and a method for setting an electrode plate cutter, which are newly configured to allow only the cutter to be easily detached during cutter regrinding. [Background technology]

[0002] Secondary batteries include lithium secondary batteries such as nickel cadmium batteries, nickel metal hydride batteries, lithium batteries, and lithium ion batteries. In general, a lithium secondary battery includes an electrode assembly including a positive electrode plate coated with a positive electrode active material, a negative electrode plate coated with a negative electrode active material, and a separator interposed between the positive electrode plate and the negative electrode plate to prevent short circuits and allow only the movement of lithium ions, a lithium secondary battery case that houses the electrode assembly, and an electrolyte that is injected into the lithium secondary battery case to allow the movement of lithium ions.

[0003] Here, the base substrate on which the active material layer is formed is cut into length units for secondary battery electrode plates using an electrode plate cutting device, thereby forming secondary battery electrode plates.

[0004] The electrode plate cutting device generally comprises an upper cutter and a lower cutter, and a constant gap is maintained between the upper cutter and the lower cutter.

[0005] When a positive electrode substrate substrate or a negative electrode substrate substrate coated with a positive electrode active material or a negative electrode active material is fed between an upper cutter and a lower cutter into an electrode plate cutting device, the substrate substrate is cut into an electrode plate for a secondary battery by the operation of the upper cutter or the lower cutter.

[0006] However, in the conventional cutter regrind, not only the cutter but also other peripheral parts must be removed and attached, making it difficult to simplify maintenance and repair, and it is difficult to ensure consistent cutting quality of the electrode plate when assembling the cutter.

[0052] In addition, according to the present invention, there is provided a method for setting an electrode plate cutter, comprising: an upper cutter aligning step of aligning a coupling support slit 162 formed long in the left-right width direction on at least one of both sides of the upper cutter 132 and penetrating the left and right side ends and the one side of the upper cutter 132 to match a guide pin 164 provided on the upper cutter holder 130; an upper cutter coupling step of inserting the guide pin 164 into the coupling support slit 162 of the upper cutter 132 to position the upper cutter 132 on the upper cutter holder 130; and an upper cutter fixing step of fixing the upper cutter 132 to the upper cutter holder 130 by a set bolt 166.

[0053] In addition, according to the present invention, there is provided a plate cutter setting method, which further includes a step of loosening the set bolt 166 when it is necessary to separate the upper cutter 132 from the upper cutter holder 130, and an upper cutter separation step of separating the upper cutter 132 from the guide pin 164 and from the upper cutter holder 130 in a state in which the set bolt 166 is loosened.

[0054] Meanwhile, according to the present invention, the piston rod of the cutter contact cylinder 142 is connected to the vertical tilting operation piece 143 via a connecting hinge. Here, the connecting hinge is relatively rotatably coupled to the piston rod of the cutter contact cylinder 142, and includes a connecting hinge pin arranged in a direction parallel to the left and right end directions of the cutter support frame, and a connecting pinhole formed inside the vertical tilting operation piece 143.

[0055] As the piston rod of the cutter contact cylinder 142 moves forward or backward, the vertical tilting operation piece 143 can rotate (tilt) in the vertical direction with respect to the piston rod of the cutter contact cylinder 142 with respect to the connecting hinge. When viewed from one side of the cutter support frame, as the piston rod of the cutter contact cylinder 142 moves forward or backward, the vertical tilting operation piece 143 can rotate (tilt) in the vertical direction with respect to the piston rod of the cutter contact cylinder 142 with respect to the connecting hinge. Such an operation can be referred to as a vertical tilting operation.

[0056] The present invention is characterized in that the upper cutter 132 is rotated vertically by the upper cutter tilting unit to perform vertical tilting operation, thereby bringing the upper cutter 132 into close contact with the lower cutter 152, thereby making the cut surface of the electrode plate cut by the upper cutter 132 and the lower cutter 152 uniform and cutting the electrode plate smoothly.

[0057] The process of tilting the upper cutter 132 up and down by the upper cutter tilting unit will be described below.

[0058] The left-right tilting reference block 146 and the up-down tilting reference block 145 are connected by a vertically arranged tilting hinge 147, and the up-down tilting operation piece 143 is connected (connected via the connecting hinge) to the cylinder rod of the cutter contacting cylinder 142 mounted on the cutter support frame 120, and the up-down tilting operation piece 143 is connected to the up-down tilting reference block 145 by a horizontally arranged tilting hinge 144, so that when the piston rod of the cutter contacting cylinder 142 is advanced, the cutter contacting cylinder 142 is connected to the up-down tilting operation piece 143 by a horizontally arranged tilting hinge 144. The vertical tilting actuating piece 143 connected to the cylinder rod of the cylinder 142 tilts (rotates) a certain angle in the vertical direction based on the lower cutter 152 when viewed from one side of the cutter support frame 120, so that the upper cutter holder 130 and the upper cutter 132 connected to the vertical tilting actuating piece 143 also tilt (rotate) a certain angle in the vertical direction based on the lower cutter 152 when viewed from one side of the cutter support frame 120, and as a result, the upper cutter 132 can be tilted in the vertical direction based on the lower cutter 152.

[0059] In this manner, the upper cutter 132 is tilted vertically based on the lower cutter 152, so that the lower cutter 152 and the upper cutter 132 can be in close contact with each other.

[0060] 11 and 12, the vertical tilting operating piece 143, the horizontally disposed tilting hinge 144, the vertical tilting reference block 145, and the horizontal tilting reference block 146 can be rotated horizontally based on the vertically disposed tilting hinge 147, thereby allowing the upper cutter holder 130 and the upper cutter 132 to be tilted horizontally with respect to the lower cutter 152 disposed below. In this manner, when viewed from above the cutter support frame 120, the upper cutter 132 can be tilted horizontally by a certain angle based on the lower cutter 152, so that the lower cutter 152 and the upper cutter 132 can be in close contact with each other.

[0061] Therefore, in the present invention, by tilting the upper cutter 132 in the vertical direction and the horizontal direction through the operation of the upper cutter tilting unit as described above, the lower cutter 152 and the upper cutter 132 can be brought into complete contact with each other (i.e., the rear surface of the upper cutter 132 and the front surface of the lower cutter 152 can be brought into complete contact with each other), and in this state, the upper cutter 132 and the lower cutter 152 can cross to cut the secondary battery plate, thereby improving the quality of the cut surface of the plate. It is expected that the improvement in the quality of the cut surface of the plate will improve the quality of the secondary battery having the plate built in.

[0062] Also, the present invention is characterized in that only the upper cutter 132 can be disassembled and assembled.

[0063] The process of disassembling and assembling the upper cutter 132 of the present invention will be described below.

[0064] A coupling support slit 162 (see FIG. 6) formed on at least one side of the upper cutter 132 in a lateral direction is aligned to coincide with a guide pin 164 provided on the upper cutter holder 130 .

[0065] Next, the upper cutter 132 is pushed from one end to the other end of the upper cutter holder 130. Then, the coupling support slits 162 of the upper cutter 132 slide along a number of guide pins 164 provided on the upper cutter holder 130, so that the guide pins 164 can be inserted into the coupling support slits 162 of the upper cutter 132, thereby allowing the upper cutter 132 to be positioned in the upper cutter holder 130.

[0066] Next, the upper cutter 132 is fixed to the upper cutter holder 130 by a set bolt 166. When the set bolt 166 is inserted into the set bolt insertion holes penetrating both sides of the upper cutter 132 and the set bolt 166 is fastened to the set bolt 166 fastening hole formed in the upper cutter holder 130 by a bolt method, the head of the set bolt 166 holds the upper cutter 132, so that the upper cutter 132 can be supported to be fixed to the upper cutter holder 130.

[0067] Here, the upper cutter 132 can be primarily connected to the upper cutter holder 130 by pushing the connection support slit 162 of the upper cutter 132 in from the front side of the guide pin 164 so that the upper cutter 132 is hooked onto the guide pin 164, and then the set bolt 166 is tightened to connect the upper cutter 132 to the upper cutter holder 130.

[0068] Therefore, according to the present invention, with the upper cutter holder 130 attached to the cutter support frame 120, only the upper cutter 132 can be separately assembled to the upper cutter holder 130. This simplifies the structure, and therefore, it is possible to ensure consistent quality during electrode cutting regardless of who is assembling the plate (setting). Furthermore, the assembly work of the upper cutter 132 can be easily and quickly performed.

[0069] Also in accordance with the present invention, when it is necessary to separate the upper cutter 132 from the upper cutter holder 130, the set bolt 166 is loosened.

[0070] Next, with the set bolt 166 loosened, the upper cutter 132 is slid and pulled out toward one end of the upper cutter holder 130 or the other end of the stripper. When the upper cutter 132 is pulled toward one end or the other end of the upper cutter holder 130, the coupling support slits 162 of the upper cutter 132 slide along a number of guide pins 164 provided on the upper cutter holder 130, so that the upper cutter 132 can be separated while leaving the upper cutter holder 130 as it is.

[0071] Here, with the set bolt 166 loosened, the upper cutter 132 can be separated from the upper cutter holder 130 by pulling the coupling support slit 162 of the upper cutter 132 out in front of the guide pin 164 .

[0072] Therefore, the present invention can simplify maintenance and repair by allowing only the cutter to be easily detached during cutter regrinding, and it is expected that the cutting cross-section quality of the electrode plate cut by the cutter will be improved by simplifying the cutter maintenance and repair.

[0073] As shown in FIG. 5, according to the present invention, the cutting guide pieces 132C provided on both the left and right sides of the upper cutter 132 are provided with upper cutting inclined guide surfaces 132CG inclined downward toward the front side at a part of the rear surface thereof, and the lower end of the cutting guide piece 132C is connected to the lower end of the upper cutting inclined guide surface 132CG. When the upper cutter 132 is viewed from one side, the cutting guide pieces 132C are OfSince the side lower end is configured to be located in a position forward of the outer upper end of the lower cutter 152, when the upper cutter 132 is lowered as described above while the upper cutter 132 is placed on the lower cutter 152, the pair of left and right cutting guide pieces 132C enter the upper end of the lower cutter 152 first and descend. At this time, the sharp blade at the lower end of the upper blade 132B, which is a main part of the upper cutter 132, does not come into contact with the upper end of the lower cutter 152 due to the upper cutting inclined guide surface 132CG, and smoothly descends while crossing the lower cutter 152. This reliably prevents the upper cutter 132 from crossing the lower cutter 152 normally and being unable to descend while crossing the lower cutter 152 during the descent of the upper cutter 132. In this way, it is possible to more reliably prevent the case where the upper cutter 132 does not cross the lower cutter 152 normally and being unable to descend while crossing the lower cutter 152 during the descent of the upper cutter 132.

[0074] Meanwhile, as shown in FIG. 13, the upper cutter 132 can be configured to include a horizontal blade 132HB extending horizontally from the center in the vertical direction to the left and right when viewed from the front, and a pair of left and right inclined blades 132SB respectively connected to the horizontal blade 132HB.

[0075] When the upper cutter 132 descends and intersects with the lower cutter 152 to cut the electrode plate, the horizontal blade 132HB prevents the center of the electrode plate from being crushed and causing wrinkles, so that it is expected that the cutting quality of the cut surface of the electrode plate can be more reliably guaranteed.

[0076] Meanwhile, according to another embodiment of the present invention, as shown in Fig. 9, the upper cutter 132 may be configured to have a blade inclined upward from one side end to the other side end at the lower end when viewed from the front, so that the upper cutter 132 has a one-sided blade 132PB when viewed from the front. In this case, the electrode plate can be cut by the one-sided blade 132PB of the upper cutter 132.

[0077] In the case of an embodiment in which a one-sided blade 132PB is provided at the lower end of the upper cutter 132, the above-mentioned configuration is maintained as is, so in the embodiment in which an upper cutter 132 equipped with a one-sided blade 132PB is used, a duplicated explanation of the above-mentioned overlapping configuration and the effects thereof will be omitted.

[0078] Also, as shown in FIGS. 14 and 15, according to the present invention, a manual lever is provided whose tip end is connected to the cutter support frame 120 by a hinge, and a middle portion of the manual lever is connected to the upper cutter holder 130. When an operator holds the manual lever and lowers it based on the hinge connected to the cutter support frame 120, the upper cutter tilting unit, the upper cutter holder 130 and the upper cutter 132 are lowered and intersect with the lower cutter 152 to manually cut the electrode plate.

[0079] The above-described configuration is maintained in the embodiment having the manual lever, so that a duplicated description of the above-described duplicated configuration and the effects thereof will be omitted for the embodiment employing the manual lever.

[0080] Here, a lever pivoting cylinder arranged vertically is mounted on the cutter support frame 120, and a cylinder rod of the lever pivoting cylinder is connected to a base end side of a manual lever. When the cylinder rod of the lever pivoting cylinder is lowered to lower the manual lever based on the hinge connected to the cutter support frame 120, the upper cutter tilting unit, the upper cutter holder 130, and the upper cutter 132 are lowered and intersect with the lower cutter 152 to manually cut the electrode plate.

[0081] Also, as shown in FIG. 1 and FIG. 2, according to the present invention, a tilting cylinder regulator RG is mounted on the cutter frame, and the tilting cylinder regulator RG is connected to the internal pressure chamber of the tilting operation cylinder, in other words, the cutter contact cylinder 142, via a flexible pressure supply pipe (not shown). Therefore, the pressure supplied to the internal pressure chamber of the cutter contact cylinder 142 can be adjusted by the tilting cylinder regulator RG, which has the effect of more precisely adjusting the vertical tilting angle and the horizontal tilting angle of the upper cutter holder 130 and the upper cutter 132.

[0082] In addition, as shown in FIGS. 1 and 2, a stripper cylinder regulator RG is mounted on the cutter frame, and the stripper cylinder regulator RG is connected to an internal pressure chamber of a stripper operating cylinder, in other words, a stripper operating cylinder 123 having a cylinder rod connected to an upper cutter holder 130, via a flexible pressure supply pipe (not shown). As a result, the pressure supplied to the internal pressure chamber of the stripper operating cylinder 123 can be adjusted by the stripper cylinder regulator RG. Therefore, by precisely adjusting the elevation degree of the upper cutter holder 130 and the upper cutter 132, it is possible to expect an effect of further improving the cutting quality of the cut surface of the electrode plate cut by the upper cutter 132 and the lower cutter 152.

[0083] Meanwhile, as shown in FIG. 7, a first type upper cutter 132 (III-I) according to the present invention has a V-shape, a cutting edge angle of 90°, and a shear angle of 3°.

[0084] Also, as shown in FIG. 8, the second type upper cutter 132 (III-II) according to the present invention has a V-shape, a cutting edge angle of 30°, and a shear angle of 3°.

[0085] And, as shown in FIG. 9, the third type upper cutter 132 (III-III) according to the present invention has a one-side shear angle of 2° and a cutting edge angle of 30°.

[0086] Meanwhile, according to the present invention, the lower cutter 152 is detachably connected to the lower stripper by a fixing means such as a fixing bolt. The lower cutter 152 is provided with a front cutting tip 153 and a rear cutting tip 154 ​​at its front upper end and rear lower end, respectively. When the front cutting tip 153 is worn out due to long-term use, the front and rear surfaces of the lower cutter 152 are rotated 180 degrees and then attached to the lower stripper by the fixing means. This allows the rear cutting tip 154 ​​of the lower cutter 152 to perform the electrode plate cutting operation together with the upper cutter 132. This is expected to have an effect of extending the life of the lower cutter 152 by more than twice.

[0087] The present invention described above is not limited to the above-mentioned embodiments, and it will be understood by those having ordinary skill in the art to which the present invention pertains that various modifications and variations are possible within the scope of the present invention without departing from the spirit and scope of the present invention.

[0088] Therefore, it should be understood that the above-described embodiments are provided to fully inform those skilled in the art of the present invention of the scope of the invention, and are therefore illustrative and not limiting in all respects, and the present invention is defined only by the claims.
