That is, the guide part 162 may fix the compression roller 161 and at the same time give the degree of freedom in which the compression roller 161 may move along the second direction.

The lateral adjustment lever 163 may move the compression roller 161 along the second direction between the third position (see P3 in FIG. 5) and the fourth position (see P4 in FIG. 4) by the user's manipulation. . That is, the user may rotate the lateral adjustment lever 163 about the virtual line H extending along the second direction to reciprocate the compression roller 161 along the second direction.

On the other hand, Figure 1 shows a state in which the lateral adjustment lever 163 is composed of a rotary lever, embodiments of the present invention is not limited thereto. For example, the lateral press unit 160 has an opening hole (not shown) that is open toward the first direction, and the user adjusts the position of the lateral press unit 160 to position the lateral press unit 160 at a desired position. After this, by inserting a separate fixing member (not shown) into the opening hole, it is also possible to apply a structure that prevents the movement in the second direction of the transverse pressing portion 160.

In addition to this, the lateral pressing portion 160 may include any structure that can be fixed so that the lateral pressing portion 160 does not move along the second direction. However, hereinafter, the compression roller 161 will be described based on a structure in which the compression roller 161 can be moved and fixed in the second direction by the lateral adjustment lever 163 for convenience of description.

Hereinafter, a method of sealing a seawater battery coin cell using the seawater battery coin cell sealing apparatus 100 according to an embodiment of the present invention described above with reference to FIGS. 4 to 8 will be described in detail.

4 is a flowchart illustrating a procedure of a seawater battery coin cell sealing method according to another embodiment of the present invention, FIG. 5 is a conceptual diagram schematically showing a state before the seawater battery coin cell is seated in a seating portion, and FIG. The seawater battery coin cell is seated on the seating portion, the longitudinal pressurization portion and the compression roller is a conceptual diagram showing a state that pressurizes the seawater battery coin cell, Figure 7 is a schematic view showing a state in which the longitudinal pressurization portion is in contact with one surface of the seawater battery coin cell. 8 is a conceptual diagram schematically illustrating a state in which the longitudinal pressurizing portion and the compression roller are in contact with one surface and the side surface of the seawater battery coin cell, respectively.

4 to 8, a method of sealing a seawater battery coin cell CC is as follows.

First, the seawater battery coin cell (CC) is seated on the mounting portion 120 (S401). Specifically, the seawater battery coin cell CC may be seated in the inlet portion 121 formed to be drawn in a predetermined depth in the first direction (see FIG. 5).

Next, the vertical pressurizing part 150 is moved in the first direction toward the seawater battery coin cell CC, and the vertical axis pressurizing part 150 is brought into contact with one surface of the seawater battery coin cell CC (S402) (Fig. 7). In this case, as described above, the user may operate the longitudinal adjustment lever 151 to move the longitudinal press part 150 along the first direction, and in particular, the longitudinal press part 150 may be seated on the seating part 120. It may be movable between a first position P1 in contact with one surface of the seawater battery coin cell CC and a second position P2 separated from one surface of the seawater battery coin cell CC.

Next, the rotating unit 130 is driven to rotate the seating unit 120 around the virtual line V extending in the first direction (S403). At this time, since the seawater battery coin cell CC is seated in the inlet part 121 formed in the seating part 120, the seawater battery coin cell CC may also rotate as the seating part 120 rotates. In addition, the vertical pressurizing unit 150 that presses one surface of the seawater battery coin cell CC may also rotate together with the seawater battery coin cell CC. That is, by the rotational drive of the rotation drive unit 130, the seating unit 120, the seawater battery coin cell (CC) and the longitudinal pressing unit 150 rotates around a virtual line (V) extending in the first direction. (See FIG. 6).

Next, the compression roller 161 is moved in the second direction, and the compression roller 161 is brought into contact with at least part of the side surfaces of the seawater battery coin cell CC to press the side surface of the seawater battery coin cell CC ( S404) (see FIGS. 6 and 8).

A third position P3 for contacting at least a portion of the side surface of the battery coin cell CC to pressurize the side surface of the seawater battery coin cell CC, and a second portion separated from at least a portion of the side surface of the seawater battery coin cell CC. It may be movable between four positions P4.

As such, when the compression roller 161 presses the side surface of the seawater battery coin cell CC by contacting a part of the side surface of the seawater battery coin cell CC, specifically, the second direction along the side surface of the compression roller 161. The protruding portion 161p formed to protrude into the contact portion may contact each other with at least some of the side surfaces of the seawater battery coin cell CC to pressurize the side surface of the seawater battery coin cell CC. In this case, the friction force generated between the protrusion 161p and at least some of the side surfaces of the seawater battery coin cell CC may be less than the maximum static friction force. That is, when at least a portion of the protrusion part 161p and the side surface of the seawater battery coin cell CC are in contact with each other and the side surface of the seawater battery coin cell CC is pressed, the compression roller 161 is a seawater battery coin cell CC. According to the rotation of the seawater battery coin cell (CC) can be rotated with the seawater battery coin cell (CC) without engaging with each other at least a portion of the side sliding (see Figure 6).

Here, 'part of the side' of the seawater battery coin cell (CC) is an expression in consideration of the case where the inlet 121 is not formed in the seating portion 120. That is, the seawater battery coin cell CC may be sealed while seated on the seating part 120 in which the inlet part 121 is not formed, although not shown in a separate drawing. In this case, since the whole side surface of the seawater battery coin cell CC is exposed toward the second direction, it means that the protrusion 161p and the whole side surface of the seawater battery coin cell CC may be engaged as a result.

As described above, the seawater battery coin cell CC may be fixed in the first direction by the longitudinal press unit 150 in a state of being seated on the seating unit 120, and also by the compression roller 161. Direction can be fixed. In this state, when the seawater battery coin cell (CC) is rotated by the drive of the rotary drive unit 130, the longitudinal pressurization unit 150 also rotates with the seawater battery coin cell (CC), the compression roller 161 It can also rotate with the seawater battery coin cell (CC). At this time, the compression roller 161 may press at least a part of the side surface of the seawater battery coin cell (CC) to seal the side surface of the seawater battery coin cell (CC) (see FIG. 6).

According to the seawater battery coin cell sealing apparatus 100 and the method according to the embodiments of the present invention as described above, the deformation of the seawater battery coin cell (CC) based on the first direction can be prevented, the second Based on the direction, the side surface of the seawater battery coin cell (CC) may be pressed to seal the seawater battery coin cell (CC). Therefore, it is possible to prevent the risk that the seawater battery coin cell CC is deformed or damaged by the force applied along the first direction, thereby protecting the ceramic solid electrolyte sealed inside the seawater battery coin cell CC. Can be.
