- the electrode manufacturing device (1) may further include a frame (30) and/or a filtering device.
- the above slitting roll (10) and bracket (20) may be devices included in a slitting process in an electrode manufacturing process.

- the electrode manufacturing process may further include, for example, an electrode (E) drying process, etc.
- the slitting roll (10) and bracket (20) may be included in a slitting process among the above multiple processes.
- FIG. 2 is a drawing for explaining a slitting roll (10) included in the electrode manufacturing device (1) of FIG. 1.
- the slitting roll (10) may be configured to have an approximately cylindrical shape.

- the knife (11) may be arranged parallel to the moving direction of the electrode (E). Accordingly, the electrode (E) may be cut along a line parallel to the moving direction.
- the above slitting roll (10) may include a plurality of knives (11). At this time, the spacing between the knives (11) may vary depending on the size specifications of a specific battery.

- another conventional electrode manufacturing device includes a slitting roll including a knife, and a suction device and a blow device located downstream of an electrode (E) in the moving direction, which is spaced apart from the slitting roll by a predetermined distance. More specifically, the slitting roll, the blow device, and the suction device are arranged in that order along the moving direction of the electrode (E). With this structure, foreign substances generated at a cut portion of the electrode (E) can first be blown away by the blow device and then removed by the suction device. However, with this structure, since the blow device and the suction device are located on the same side with respect to the electrode (E) and spaced apart from each other by a predetermined distance, an electrode shaking phenomenon may occur.
- the blow device applies downward pressure to the electrode (E) as shown in FIG. 4 and the suction device pulls the electrode (E) upward, there is a possibility that the electrode (E) may bend in a lying S shape. Accordingly, the inventors of the present invention have developed an electrode manufacturing device to solve all of the above problems, which will be described in detail with reference to FIGS. 5 to 11 below.
- FIG. 5 is a side view of the electrode manufacturing device (1) of FIG. 1

- the micro hole (H) included in the bracket (20) of the present invention may be configured to include both a blow hole (BH) and a suction hole (SH).
- the bracket (20) includes both a blow hole (BH) and a suction hole (SH)
- the distance between the blow hole (BH) and the suction hole (SH) is reduced, so that a fine air flow can be formed. Accordingly, the electrode shaking phenomenon can be prevented. That is, as shown in Fig. 5, a fine air layer is formed in an area adjacent to the electrode (E), so that the phenomenon of the electrode (E) sagging or bending can be prevented. Accordingly, wrinkles that may occur on the electrode (E) can be smoothed out.
- the electrode manufacturing device (1) may include an air injector (50) that is connected to the blow hole (BH) through a pipe and discharges air; and an air suction device (40) that is connected to the suction hole (SH) through a pipe and sucks air.
- the air injector (50) and/or the air suction device (40) may be composed of an air pump and/or an air pressure.
- the air injector (50) and/or the air suction device (40) may be connected to the bracket (20).
- the air injector (50) may be connected to a blow hole (BH) provided in the bracket (20) through a pipe so as to discharge air through the blow hole (BH).

- a distance between the upper bracket (21) and the electrode (E) may be approximately the same as a distance between the lower bracket (22) and the electrode (E).
- Fig. 7 is a side view of the bracket (20) of Fig. 6.
- the micro hole (H) of the lower bracket (22) provided at a position facing the micro hole (H) of the upper bracket (21) may be the same type of micro hole (H) as the micro hole (H) provided in the upper bracket (21).

- the forces applied upward and downward to the electrode (E) at a specific point of the electrode (E) can be canceled out, thereby preventing the electrode (E) from bending or shaking.
- a suction hole (SH) is provided at a specific position of the upper bracket (21) and a blow hole (BH) is provided at a corresponding position of the lower bracket (22)
- the electrode (E) interposed therebetween can receive an upwardly pulling force by the suction hole (SH) of the upper bracket (21) and an upwardly pushing force by the blow hole (BH) of the lower bracket (22). Accordingly, the electrode (E) at the specific point is more likely to bend upward.
- the electrode (E) interposed at this point is pressured downward by the blow hole (BH) of the upper bracket (21) and is pulled downward by the suction hole (SH) of the lower bracket (22). Accordingly, the electrode (E) is more likely to bend downward at the point. As a result, the electrode (E) is pressured upward and downward, which increases the possibility of electrode shaking and bending.
- the force received by the electrode (E) at a specific point of the electrode (E) can be offset from each other.
- the micro hole (H) provided at the leftmost side of the upper bracket (21) can be a blow hole (BH)
- the micro hole (H) of the lower bracket (22) provided at a corresponding position can also be a blow hole (BH).
- the electrode (E) interposed between the upper bracket (21) and the lower bracket (22) receives downward pressure by the upper bracket (21) and, at the same time, upward pressure by the lower bracket (22). Accordingly, the upward pressure and downward pressure applied to the electrode (E) cancel each other out, so that the electrode (E) may not be detached upwardly and downwardly. In other words, electrode shaking and electrode bending may be prevented.
- the micro hole (H) provided at the second from the left of the upper bracket (21) may be a suction hole (SH), and the micro hole (H) of the lower bracket (22) provided at a corresponding position may also be a suction hole (SH).
- the electrode (E) interposed between the upper bracket (21) and the lower bracket (22) receives upward pressure by the upper bracket (21) and, at the same time, downward pressure by the lower bracket (22). Therefore, the upward pressure and downward pressure applied to the electrode (E) cancel each other out, so that the electrode (E) may not be detached upwardly and downwardly. In other words, electrode shaking and electrode bending may be prevented.
- blow hole (BH) and the suction hole (SH) can be arranged crosswise.
- the blow holes (BH) and the suction holes (SH) may be arranged in an alternating manner within one bracket (20).
- the blow holes (BH) and the suction holes (SH) may be arranged in a checkerboard pattern. That is, the micro holes (H) located above, below, left, and right of the suction hole (SH) may be blow holes (BH). Similarly, the micro holes (H) located above, below, left, and right of the blow hole (BH) may be suction holes (SH).
- a thin air layer can be formed in a direction parallel to the electrode (E). Accordingly, it is possible to prevent a phenomenon in which pressure is applied to the electrode (E) in a direction perpendicular to the electrode (E) at a specific point.
