Description

Electrode manufacturing device {ELECTRODE MANUFACTURING DEVICE}

The present invention relates to an electrode manufacturing device, and more specifically, to an electrode manufacturing device that prevents continuously supplied electrode sheets from being broken or damaged and cuts the electrode sheets.

To manufacture a secondary battery, an electrode active material slurry is first applied to a positive electrode current collector and a negative electrode current collector to manufacture a positive electrode and a negative electrode, and these are stacked on both sides of a separator to form an electrode assembly of a predetermined shape. Then, the electrode assembly is stored in the battery case, and the electrolyte is injected and sealed.

Generally, to manufacture electrodes such as positive and negative electrodes, a loader unwinds a wound electrode sheet (electrode current collector), and a conveyor transfers the electrode sheet, applying slurry and forming an electrode tab. Then, an electrode cutting device cuts it to a certain size, thereby producing an electrode. Therefore, in the process of manufacturing an electrode, an electrode cutting device that cuts the electrode to a certain size is absolutely necessary.

Initially, electrodes were manufactured by cutting electrode sheets moving by a conveyor with a cutting unit that was fixed at a specific location and moved vertically up and down. However, because the electrode sheet is continuously supplied and transported, there were frequent situations in which the cut cross section of the electrode sheet was damaged by hitting the blade of a cutting unit that was fixed at a specific position and cut the electrode sheet. Of course, the movement of the electrode sheet can be stopped only while the blade of the cutting unit is lowered and cutting the electrode sheet to prevent the electrode sheet from being damaged by hitting the side of the blade of the cutting unit. However, this method can prevent the electrode sheet from being damaged by hitting the side of the blade of the cutting unit. The disadvantage is that the process efficiency is very low because the process must be stopped.

Conventionally, in order to prevent the phenomenon of collision between the electrode sheet transported horizontally and the blade of the cutting unit moving vertically up and down as described above, a cutting unit was developed that moves horizontally and cuts the electrode sheet in accordance with the movement of the electrode sheet in a specific area. It has been done.

Figure 1 shows the configuration of a conventional cutting unit 200' that moves horizontally along the transfer trajectory of the electrode sheet 10' and cuts the electrode sheet 10'. Referring to FIG. 1, the cutting unit 200' is located at the top and bottom of the electrode sheet 10', respectively, and includes an upper guide plate that guides the transferred electrode sheet 10' to the blade position of the cutting unit. (300') and the lower guide plate (400'). At this time, the upper guide plate 300' and the lower guide plate 400' guide the electrode sheet 10' at the upper and lower parts of the electrode sheet 10' according to the horizontal movement of the cutting unit 200'. and move. However, when a cutting unit 200' having the structure of FIG. 1 is used, the surface of the electrode sheet 10' is cut by the lower guide plate 400' that supports the lower surface of the electrode sheet 10' and moves horizontally. A serious problem may occur in that the electrode sheet 10' is damaged or movement of the electrode sheet 10' is impeded.

Figure 2 shows the operation of the conventional cutting unit 200' of Figure 1. Referring to FIG. 2(a), the cutting unit 200' is located between two conveyors 100' spaced apart in the horizontal direction and moves forward and backward along the transfer trajectory of the electrode sheet 10'. Figure 2(b) shows the operation of the cutting unit 200' of Figure 2(a) observed from the bottom. When the cutting unit 200' moves in the opposite direction to the electrode sheet transfer direction D', the lower part It can be seen that the guide plate 400' is in contact with the lower surface of the electrode sheet 10', preventing the transfer of the electrode sheet 10', and the lower surface of the electrode sheet 10' is damaged due to friction. there is.

For the above reasons, there is a need for research into an electrode manufacturing device with a new structure that can solve various problems caused by the lower guide plate.

Korean Patent Publication No. 10-2020-0008254

Therefore, according to the present invention, a new structure is designed to prevent damage to the lower surface of the electrode sheet by minimizing the contact between the electrode sheet and the guide plate that guides the transported electrode sheet to the cutting unit and the friction caused by the contact. The purpose is to provide an electrode manufacturing device.

Hereinafter, with reference to FIGS. 3 to 11, an electrode manufacturing apparatus according to two embodiments of the present invention will be described.

(First Embodiment)

The present invention relates to an electrode manufacturing apparatus 1000 for cutting a continuously supplied electrode sheet 10. Figure 3 is a perspective view of the electrode manufacturing apparatus 1000 according to the first embodiment of the present invention, and Figure 4 is a This is an example of applying the electrode manufacturing apparatus 1000 of FIG. 3 to the transported electrode sheet 10, and FIGS. 5 and 6 show the electrode manufacturing apparatus of FIG. 3 in which the cutting unit 210 moves relative to the guide portion 223. Each device 1000 is shown, and FIG. 7 shows the operation of the top coat 211 moving relative to the bottom coat 212 in the electrode manufacturing device 1000 of FIG. 3, and FIG. 8 shows the electrode manufacturing device 1000 of FIG. 3.

For reference, although omitted in the drawing, in order to cut the electrode sheet 10 by the electrode manufacturing apparatus 1000 of the present invention, the top coat 211, the bottom coat 212, and the driving unit that drives them are aligned at a predetermined timing. It is obvious to those skilled in the art that it must be driven and that a known controller such as a PLC (Programmable Logic Controller) must be used for this operation.

The supply unit continuously supplies electrode sheets 10 in which a plurality of electrode layers 11 are spaced apart at predetermined intervals.

Specifically, the supply unit supports the lower surface of the electrode sheet 10, rotates clockwise and transports the electrode sheet 10 to the cutting unit, and a lower conveyor 112, and is located on the lower conveyor 112 It consists of an upper conveyor 111 that presses and supports the upper surface of the electrode sheet 10 and rotates counterclockwise. That is, the electrode sheet 10 is inserted between the upper conveyor 111 and the lower conveyor 112 and is transferred to the cutting unit and cut by rotation of the upper conveyor 111 and the lower conveyor 112.

The cutting unit is located adjacent to the supply unit and cuts the electrode sheet 10 transferred at a constant speed from the supply unit at a specific position.

Specifically, the cutting part is located adjacent to the fixed guide plate 220 and the fixed guide plate 220 for supporting the lower portion of the electrode sheet 10 to be transferred and moves along the transfer trajectory of the electrode sheet 10, It consists of a cutting unit 210 that cuts the cut portion of the electrode sheet 10.

The fixed guide plate 220 supports the lower surface of the transported electrode sheet 10 and is used for aligning and guiding the electrode sheet 10.

The fixed guide plate 220 has an upper surface height that is the same as the upper surface height of the lower conveyor 112, or It may be arranged to be lower than the height of the upper surface of the lower conveyor 112.

Specifically, the fixed guide plate 220 includes an inclined portion 222, a support portion 221, and a guide portion 223, as shown in FIGS. 3 and 4.

The inclined portion 222 has a width longer than the width of the electrode sheet 10 to be transferred in order to support the entire lower surface of the electrode sheet 10 to be transferred. Additionally, an inclined surface is formed at the top to guide the electrode sheet 10 transferred through the conveyor 110 to the cutting unit 210.

The inclined portion 222 has an upwardly inclined surface at the top based on the transfer direction of the electrode sheet 10. Accordingly, the electrode sheet 10 transferred to the inclined portion 222 is guided to the cutting unit 210 along the inclined surface of the inclined portion 222.

The support portion 221 is a portion that primarily contacts the electrode sheet 10 and supports the lower surface in order to guide the electrode sheet 10 transported through the conveyor 110 to the cutting unit 210, as shown in Figures 3 and 3. As shown in FIG. 4, it may be arranged to partially surround the lower conveyor 112. The support part 221 extends from the inclined part 222 in the direction of the supply part and may have a plate shape.

The support portion 221 is formed to surround both sides of the conveyor 110 and can support the electrode sheet 10 transported by the conveyor 110. Therefore, as shown in FIG. 4, both edge portions of the electrode sheet 10 that is seated and transported on the lower conveyor 112 may be supported by the support portion 221.

The guide portion 223 extends from the inclined portion 222 in the electrode sheet transport direction (D) and has a width shorter than the width of the inclined portion 222.

The guide portion 223 supports the lower surface of the electrode sheet 10 until the electrode sheet 10 is cut by the cutting unit 210.

The cutting unit 210 of the present invention is arranged to be horizontally movable 212 along the guide portion 223.

The cutting unit 210 moves forward and backward along the transfer trajectory of the transported electrode sheet 10 and performs an operation of cutting the cut portion of the electrode sheet 10 at a specific position. At this time, the cut portion may preferably be between the two electrode layers 11 located at the front end of the electrode sheet 10. Through the above cutting, an electrode with only one electrode layer 11 formed on one surface can be manufactured.

Specifically, the cutting unit 210 moves back and forth and is coupled to the undercoat 212, which supports the lower surface of the electrode sheet 10 at the cut portion of the electrode sheet 10, and the undercoat 212. , It includes a top coat 211 that moves vertically and cuts the electrode sheet 10 supported on the bottom coat 212.

The lower coat 212 is connected to a driving part (not shown) that generates horizontal movement, and the upper coat 211 is coupled to the lower coat 212 and can be connected to a separate driving part (not shown) that generates vertical movement. there is. Accordingly, the top coat 211 moves according to the horizontal movement of the bottom coat 212 and can simultaneously move vertically with respect to the bottom coat 212. At this time, the lower part of the top coat 211 is formed in the shape of a blade, and the electrode sheet 10 is cut by the vertical movement.

Figures 5(a) and 5(b) are respectively top and bottom perspective views of the electrode manufacturing apparatus 1000 when the cutting unit 210 is located on the guide part 223. (Figure 5(a) is shown with the upper guide plate 230 omitted to clearly show the positions of the fixed guide plate 220 and the cutting unit 210.)

Referring to FIG. 5, a cutting unit 210 composed of an upper coat 211 and a lower coat 212 is arranged so that it can move forward and backward along the guide portion 223 (212). Specifically, the top coat 211 and the bottom coat 212 move forward and backward along the transfer trajectory of the electrode sheet 10 with the guide portion 223 of the fixed guide plate 220 interposed therebetween, as shown in FIG. 5. It is arranged so that it can be moved to (212). Accordingly, the upper coat 211 and the lower coat 212 are located at the upper and lower portions of the guide portion 223, respectively, and move forward and backward horizontally.

After the cutting unit 210 finishes cutting the top coat 211 at a specific location, the bottom coat 212 quickly moves backward to the next cut site. In addition, the undercoat 212 moves to the cut portion of the electrode sheet 10 and then moves forward on the cut portion of the electrode sheet 10 being transferred in accordance with the transfer speed of the electrode sheet 10. Therefore, it is preferable that the horizontal movement speed of the undercoat 212 is the same as or faster than the transfer speed of the electrode sheet 10.

Figures 6(a) and 6(b) are respectively top and bottom perspective views of the electrode manufacturing apparatus 1000 when the cutting unit 210 is spaced a predetermined distance away from the guide portion 223. (Figure 6(a) is shown with the upper guide plate 230 omitted to clearly show the positions of the fixed guide plate 220 and the cutting unit 210.)

Referring to FIG. 6, the cutting unit is spaced apart from the tip of the guide portion 223 of the fixed guide plate 220 by a predetermined distance.

In the electrode manufacturing apparatus 1000 of the present invention, the cutting unit 210 moves horizontally along the guide part 223 in the transport direction of the electrode sheet 10 as shown in FIG. 5, and then moves the fixed guide plate 220. ) The top coat 211 may descend at a specific position spaced apart from the electrode sheet 10 by a predetermined distance to cut the electrode sheet 10. More specifically, the specific position where the electrode sheet 10 is cut is a point where the cut portion of the electrode sheet 10 is spaced a predetermined distance from the tip of the guide portion 223 included in the fixed guide plate 220. .

The cutting unit 210 moves to the specific position on the cut portion of the electrode sheet 10 in accordance with the movement of the electrode sheet 10, and then cuts the electrode sheet 10.

Figure 7 shows that the top coat 211 included in the cutting unit 210 moves vertically with respect to the bottom coat 212. Referring to Figure 7, the top coat 211 with a blade formed at the bottom can move up and down. The undercoat (212) is coupled to the undercoat (212).

Specifically, the undercoat 212 supports the lower surface of the electrode sheet 10 at the cut portion of the electrode sheet 10 while being fixed at a specific position, and the undercoat 212 runs down one side of the undercoat 212. The electrode sheet 10 inserted between the upper coat 211 and the lower coat 212 is cut at a portion where the blade of 211 contacts the lower coat 212.

The undercoat 212 has vertical extensions 212a formed at both edges in the width direction (width direction of the electrode sheet 10), and the electrode sheet 10 has the vertical extensions 212a. It enters the space and is cut by the top coat (211). That is, the electrode sheet 10 is cut by the upper coat 211 descending between the vertical extension portions 212a and near the boundary between the lower coat 212 and the upper coat 211.

As shown in FIGS. 3 and 4, the cutting unit may be coupled to the bottom 212 and may further include an upper guide plate 230 positioned above the fixed guide plate 220.

The upper guide plate 230 serves to guide the electrode sheet 10 to the cutting unit 210 by moving it between the fixed guide plate 220.

The upper guide plate 230 includes a coupling portion 232 coupled to the undercoat 212 and an alignment portion extending from the coupling portion 232 in a direction opposite to the electrode sheet transfer direction D, and having an inclined surface at the bottom. Includes (231).

Specifically, the alignment unit 231 has a downwardly inclined surface at the bottom based on the electrode sheet transfer direction (D). The transferred electrode sheet 10 is guided to the cutting unit 210 along the inclined surface of the alignment unit 231. More specifically, the electrode sheet 10 supplied from the supply unit is cut while its upper and lower surfaces are supported by the inclined surfaces formed on the alignment portion 231 of the upper guide plate 230 and the inclined portion 222 of the fixed guide plate 220. It may be guided and transported to the unit 210.

As shown in FIGS. 3 and 4, the alignment portion 231 extends from both ends of the coupling portion 232 in a direction opposite to the electrode sheet transport direction D to surround portions of both sides of the upper conveyor 111. It can be formed as an extension. Therefore, the upper guide plate 230 moves the electrode sheet 10 transported by the conveyor 110 through the alignment portions 231 extending to both sides of the conveyor 110 before it is separated from the conveyor 110. The upper surface of the sheet 10 can be guided.

The coupling portion 232 of the upper guide plate 230 is coupled to the vertical extension portion 212a formed on both sides of the lower channel 212, and an electrode sheet is formed between the upper guide plate 230 and the fixed guide plate 220. (10) can move.

The upper guide plate 230 guides the upper surface of the electrode sheet 10 to be transported by horizontally reciprocating on the fixed guide plate 220 as the coupled channel 212 moves.

The upper guide plate 230 may be hinged to the bottom 212 so that the hinge can be moved.

Specifically, as shown in FIG. 8, the coupling portion 232 of the upper guide plate 230 is hinged to the vertical extension portion 212a of the lower channel 212, and is hinged up and down starting from the hinged axis H. Movement may be possible.

Figures 9 and 10 show the application of the electrode manufacturing apparatus 1000 of the present invention to the electrode sheet 10 being transferred. Figure 9 shows the cutting unit 210 moving as far back as possible toward the supply unit, and Figure 10 shows the cutting unit 210 moving as far back as possible. It shows that the unit 210 has moved to a specific position where the electrode sheet 10 is cut.

Referring to FIG. 9(a), the top coat 211 and the upper guide plate 230 coupled to the bottom coat 212 are positioned so that the top coat 211 is positioned on the cut portion of the electrode sheet 10 (212). It moves backward along the channel 212 in a direction opposite to the transport direction of the electrode sheet 10. As shown in FIG. 9(b), the channel 212 moves to the boundary between the inclined portion 222 and the guide portion 223 of the fixed guide plate 220. At this time, the electrode sheet 10 is guided by the fixed guide plate 220 and the upper guide plate 230 and is transferred between the upper coat 211 and the lower coat 212 of the cutting unit 210.

The extended length of the support portion 221 of the fixed guide plate 220 of the present invention may be limited by the length and moving distance of the upper guide plate 230.

FIG. 10 is a side view of the electrode manufacturing apparatus 1000 showing the cutting unit 210 moving backward to the boundary between the inclined portion 222 and the guide portion 223 of the fixed guide plate 220. That is, FIG. 10 shows a state in which the upper guide plate 230 is moved as much as possible in the direction opposite to the transfer direction of the electrode sheet 10, and the end of the upper guide plate 230 is transferred through the conveyor 110. It becomes the guide starting point (a) of the upper guide plate 230 from which to start guiding the electrode sheet 10.
