Description

Pouch case transport device and pouch case transport method using the same

[0001] This application claims the benefit of priority to Korean Patent Application No. 10-2024-0072428, filed June 3, 2024, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to a pouch case transport device and a pouch case transport method using the same, and more particularly, to a pouch case transport device capable of stably transporting a pouch case for a secondary battery without deformation of the pouch case when transporting the pouch case, and a pouch case transport method using the same.

[0003]

[0004] Recently, due to the development of alternative energy sources to address air pollution and energy depletion caused by the use of fossil fuels, demand for secondary batteries that can store generated electric energy is increasing.

[0005] Secondary batteries, the energy source for various electronic devices indispensable in modern society, are seeing increased capacity requirements due to the increasing use and complexity of mobile devices and the development of electric vehicles. To meet user demand, small devices are equipped with multiple battery cells. However, automobiles and other devices utilize battery modules, which electrically connect multiple battery cells, or battery packs comprising multiple such modules.

[0006] Meanwhile, in the process of manufacturing battery cells, the formed pouch case must be transported to a designated location, and for this purpose, many absorbent materials are used to absorb and hold the edges of the pouch case.

[0007] However, since depressurization and release are repeated, the absorbent material must be replaced at regular intervals, and since many absorbent materials must be used, the initial cost of the pouch case transport device is high.

[0008] Fig. 1 is a front view of a transport device according to the prior art. As shown in Fig. 1, a sheet transport device (9) according to the prior art includes a support (7) for supporting a sheet, an adsorption member (40) for adsorption by being in close contact with the sheet, a hollow shaft (41) connected to the adsorption member (40), and a support (42) for supporting the hollow shaft (41), and a suction hole is formed in the adsorption member (40).

[0009] The sheet transport device (9) according to the prior art has a suction hole provided in the suction member (40) that is in close contact with the sheet to suck in air and suction the sheet.

[0010] This adsorption structure can stably adsorb and transport the sheet, but the adsorption members (40) are positioned to correspond to all areas of the sheet, and this transport device still requires a large number of adsorption members (40).

[0011] In addition, when using a lot of absorbent material, there is a high possibility that the pouch case will be deformed due to the absorbent force.

[0050]

[0051] Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail, so that those skilled in the art can easily implement the present invention. However, when describing the operating principles of preferred embodiments of the present invention in detail, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the gist of the present invention, such detailed descriptions will be omitted.

[0052] Additionally, the same drawing reference numerals are used for parts with similar functions and actions throughout the drawings. Throughout the specification, when a part is said to be connected to another part, this includes not only direct connections but also indirect connections with other elements intervening. Furthermore, inclusion of a component does not exclude other components unless specifically stated otherwise, but rather implies the inclusion of additional components.

[0053]

[0054] Hereinafter, a pouch case transport device according to the present invention and a pouch case transport method using the same will be described with reference to the attached drawings.

[0055] Fig. 2 is a perspective view of a pouch case transport device according to a first embodiment of the present invention as viewed from an upper side, Fig. 3 is a perspective view of the pouch case transport device illustrated in Fig. 2 as viewed from a lower side, and Fig. 4 is a front view of the pouch case transport device illustrated in Fig. 2 as viewed from below. In addition, Fig. 5 is a cross-sectional view taken along line I-I of Fig. 3, and Fig. 6 is a cross-sectional view showing a state in which a pouch case is adsorbed on a pouch case transport device according to the first embodiment of the present invention.

[0056] Referring to FIGS. 2 to 6 together, a pouch case transport device according to the first embodiment of the present invention can be configured to include a sealing member (100), a support bar (200), and a pressure reducing member (300).

[0057] First, the pouch case (10) can be composed of a cup portion (11) that forms a certain space to accommodate an electrode assembly and an electrolyte, and an edge portion (12) that extends outward from the cup portion (11) for sealing.

[0058] Here, the pouch case (10) forms a cup portion by forming a laminate sheet composed of an outer resin layer, a metal layer, and an inner resin layer.

[0059] The outer resin layer is located at the outermost part of the pouch case (10). In order to protect the electrode assembly while ensuring heat resistance and chemical resistance, a heat-resistant polymer with excellent tensile strength, moisture permeability, and air permeability can be used. For example, nylon or polyethylene terephthalate can be used, but is not limited thereto.

[0060] The metal layer in contact with the outer resin layer serves as a barrier layer that prevents moisture or various gases from penetrating from the outside into the battery. A preferred material for this metal layer is a lightweight aluminum film with excellent formability.

[0061] In addition, since the inner resin layer is in direct contact with the electrode assembly, it must have insulation and electrolytic resistance, and in order to seal it from the outside, it must have sealing properties, that is, it must have excellent thermal bonding strength as the inner layers are thermally bonded to each other.

[0062] Materials for the internal resin layer may be selected from, but are not limited to, polyolefin resins such as polypropylene, polyethylene, polyethylene acrylic acid, and polybutylene, which have excellent chemical resistance and good sealing properties, polyurethane resins, and polyimide resins. Polypropylene, which has excellent mechanical properties such as tensile strength, rigidity, surface hardness, and impact strength, and excellent chemical resistance, is most preferable.

[0063] The contact portion (100) for transporting the aforementioned pouch case (10) may be configured to include a main plate (110) having a flat shape with a certain area, and an auxiliary plate (120) provided to protrude a certain length from the center of one side of the main plate (110) as needed.

[0064] In detail, the main plate (110) is in a roughly flat shape and is in close contact with the edge (12) of one side of the pouch case (10). At this time, the area of ​​the main plate (110) facing one side of the pouch case (10) so that most of one side of the pouch case (10) can be in close contact with the other side of the pouch case (10) may be of a similar size to one side of the pouch case (10), for example, slightly smaller, the same size, or slightly larger.

[0065] Also, based on Fig. 2, the upper surface of the main plate (110) is connected to the support bar (200), so that the main plate (110) moves together with the support bar (200), and as a result, the pouch case (10) absorbed by the main plate (110) moves to a set position.

[0066] Meanwhile, the main plate (110) may be provided with a first air passage (111), a first adsorption path (112), a second air passage (114), a storage groove (115), and an adsorption member (116) to adsorb and fix the edge (12) of the pouch case (10).

[0067] In detail, the first air passage (111) for the movement of the first air is formed in a shape penetrating the inside of the main plate (110), with one side formed to face below the main plate (110) and communicating with the first adsorption passage (112), while the other side is formed to face above the main plate (110) and is exposed to the other surface of the main plate (110).

[0068] The first adsorption urea (112) is configured to adsorb and fix one side edge (12) of the pouch case (10) by depressurization, and is formed in a shape that is sunken inward on the lower surface of the main plate (110), which is the surface facing one side of the pouch case (10).

[0069] At this time, the first adsorption path (112) is connected to the first air passage (111) and is exposed toward one side of the edge (12) of the pouch case (10). It is preferable that the first adsorption path (112) be provided as a pair spaced apart from each other by a certain distance so as to correspond to a pair of edges positioned facing each other at the edge (12) of the pouch case (10), and it is more preferable that the first adsorption path (112) be provided as two pairs spaced apart from each other by a certain distance so as to correspond to two pairs of edges positioned facing each other so as to more securely adsorb and fix the pouch case (10) (see FIG. 4).

[0070] Meanwhile, the first air passage (111) is formed in a structure in which it branches into multiple parts inside the main plate (110) and communicates with the first adsorption passage (112). By this structure, the entire area of ​​the first adsorption passage (112) can be depressurized almost simultaneously.

[0071] Although, in FIG. 4, the first adsorption path (112) is not provided in some directions (3 o'clock direction and 9 o'clock direction), the first adsorption paths (112) may be formed to be connected to each other as needed.

[0072] The vertical cross-section of the first adsorption path (112) may be circular with a portion open toward the edge (12) of the pouch case (10) (see FIG. 5).

[0073] Next, a second air passage (114) for the movement of the second air is formed in a shape penetrating the inside of the main plate (110), with one side formed to face downwards of the main plate (110) and communicating with the adsorption member (116), while the other side is formed to face upwards of the main plate (110) and is exposed to the upper surface, which is the other surface of the main plate (110).

[0074] The absorbent member (116) is configured to absorb and fix one edge portion (12) of a pouch case (10) by depressurization, and is located on one side of the main plate (110), which is the side facing one side of the pouch case (10). Specifically, a storage groove (115) having a space portion of a certain size is formed on the lower side, which is one side of the main plate (110), and at least a portion of the absorbent member (116) is located in the storage groove (115) and faces one side of the edge portion (12) of the pouch case (10).

[0075] At this time, the adsorption member (116) is positioned between the edge portion (12) facing the first air passage (111) and the cup portion (11), and it is preferable that a plurality of the adsorption members (116) are provided at a certain distance apart so as to correspond to a pair of edges positioned facing each other in the full-length direction (X-axis direction) of the pouch case (10). For example, 2 to 3 may be positioned in each full-length direction (X-axis direction), for a total of 4 to 6.

[0076] Here, the adsorption member (116) may be a suction plate that generates an adsorption force by depressurization and loses the adsorption force when the depressurization is released, and may be made of a flexible material and may have a shape that becomes wider as it goes downward, for example.

[0077] Similar to the first air passage (111), the second air passage (114) is also formed with a structure in which it branches into multiple parts inside the main plate (110) and communicates with a plurality of adsorption members (116), and by this structure, all adsorption members (116) can be depressurized almost simultaneously.

[0078] The edge portion (12) of the pouch case (10) can be adsorbed and fixed by the first adsorption path (112) or the adsorption member (116) alone, but when the first adsorption path (112) and the adsorption member (116) are provided simultaneously, the edge portion (12) of the pouch case (10) can be adsorbed and fixed more reliably, and furthermore, deformation of the pouch case (10) can be reduced by minimizing the use of the adsorption member (116).

[0079] Meanwhile, the auxiliary plate (120) is a flat plate having a smaller area than the main plate (110), and can be formed in a shape that protrudes downward from one side of the main plate (110).

[0080] It is preferable that this auxiliary plate (120) be located near the center of one side of the main plate (110) so that it can be accommodated in the cup part (11) of the pouch case (10) and come into close contact with one side of the cup part (11), and it is more preferable that it has a thickness such that when it comes into close contact with one side of the cup part (11), the main plate (110) and the edge part (12) of the pouch case (10) come into close contact or are slightly spaced apart.

[0081] Although the drawing shows that there are two auxiliary plates (120), it is obvious that the position and number of auxiliary plates (120) may change depending on the shape and number of cup portions (11) of the pouch case (10).

[0082] Of course, the auxiliary plate (120) can be omitted as needed. The auxiliary plate (120) can contribute to reducing deformation of the shape of the cup portion (11) when transporting the pouch case (10), but the auxiliary plate (120) can be omitted as needed.

[0083] Next, the support bar (200) may be a bar shape having a certain length, and one side is connected to the contact portion (100), more specifically, to the other side, which is the upper surface of the main plate (110).

[0084] Although not shown in the drawing, the support bar (200) can be controlled to be connected to a robot arm or a moving rail, etc., to move to a set position and then return to the original position. Since this operating principle corresponds to a known configuration, a detailed description will be omitted.

[0085] Also, the drawing shows the shape of the support bar (200) as a square column, but this can be changed to any shape, such as a cylinder.

[0086] Next, the pressure reducing member (300) will be described. The pressure reducing member (300) is configured to include a first pressure reducing member (310) and a second pressure reducing member (320). The first pressure reducing member (310) is configured to maintain the first air passage (111) at a certain level of pressure reduction, and may include a first air pipe (311) connected to the first air passage (111) exposed to the other surface of the main plate (110), and a first pressure reducing pump (312) connected to the first air pipe (311).

[0087] In addition, the second pressure reducing member (320) is configured to maintain the second air passage (114) at a certain level of pressure reduction, and may include a second air pipe (321) connected to the second air passage (114) exposed to the other surface of the main plate (110), and a second pressure reducing pump (322) connected to the second air pipe (321).

[0088] Here, the first air pipe (311) and the second air pipe (321) may be made of a material having flexibility and elasticity, and there are no particular restrictions as long as the material does not affect the pressure reduction force when the first pressure reducing pump (312) and the second pressure reducing member (320) are driven.

[0089] Drawing symbol V1 is a first opening / closing valve provided in the first air pipe (311), and drawing symbol V2 is a second valve provided in the second air pipe (321).

[0090] To briefly explain the operating principle of the aforementioned pressure reducing member (300), when the first pressure reducing pump (312) operates, air from the first air pipe (311) and the first air passage (111) is sucked in to maintain the first adsorption path (112) in a pressure reducing state at a certain level, and as a result, the edge portion (12) of the pouch case (10) can be pressed and adsorbed.

[0091] In addition, when the second pressure reducing pump (322) operates, air from the second air pipe (321) and the second air passage (114) is sucked in to maintain the adsorption member (116) at a certain level of pressure reduction, and as a result, the edge (12) of the pouch case (10) can be pressed and adsorbed.

[0092] Meanwhile, it is also possible to operate in a depressurized state by sucking the air of the first air passage and the second air passage together using a single depressurizing member, for example, a single air pipe equipped with an on-off valve and a single depressurizing pump. However, in this case, it is practically impossible to individually control the depressurization force of the first air passage and the second air passage, and furthermore, if a problem occurs in the air pipe or the depressurizing pump, the pouch case cannot be sucked at all. Therefore, it is preferable to separately provide the first depressurizing member (310) and the second depressurizing member (320).

[0093] Fig. 7 is a cross-sectional view of a pouch case transport device according to a second embodiment of the present invention. Referring to Fig. 7, the pouch case transport device according to the second embodiment of the present invention is identical to the pouch case transport device according to the first embodiment described with reference to Figs. 2 to 6 except for the shape of the first adsorption path (112), and therefore, a description of the same configuration will be omitted.

[0094] The pouch case transport device according to the second embodiment has a vertical cross-section of the first adsorption path (112) that is a square shape with a portion open toward the edge (12) of the pouch case (10).

[0095] Although the vertical cross-section of the first adsorption path (112) is depicted as a partially open rectangular shape in FIG. 7, the vertical cross-section may be formed as a polygon such as a partially open triangle, pentagon, hexagon, or octagon.

[0096] FIG. 8 is a perspective view of a pouch case transport device according to a third embodiment of the present invention viewed from a lower side, and FIG. 9 is a front view of the pouch case transport device illustrated in FIG. 8 viewed from a lower side.

[0097] Referring to FIGS. 8 and 9, the pouch case transport device according to the third embodiment of the present invention is identical to the pouch case transport device according to the first embodiment described in FIGS. 2 to 6, except that the main plate (110) is further provided with a second adsorption path (113), and therefore, a description of the same configuration will be omitted.

[0098] The pouch case transport device according to the third embodiment is additionally provided with a second adsorption path (113) having a predetermined pattern so as to be connected to the first adsorption path (112).

[0099] At this time, the second adsorption path (113) may have a shape consisting of one or more circular shapes and one or more linear or curved shapes so as to be in communication with the first adsorption path (112).

[0100] As an example, the second adsorption path (113) according to the third embodiment may have a pattern shape composed of a plurality of circles having the same center and different diameters, and one or more lines crossing the center and connecting these circles to each other.

[0101] To explain in more detail, the second adsorption path (113) is centered at the first adsorption path (112) or at the point where the first adsorption paths (112) intersect each other, and has one, more preferably two or more circles positioned around the center, and can be configured with one or more lines crossing the center so as to connect them to each other.

[0102] Therefore, when the first air passage (111) and the first adsorption passage (112) are depressurized, the second adsorption passage (113) also becomes depressurized.

[0103] In particular, the second adsorption path (113) has a pattern shape, so that the adsorption area is wide, and a plurality of them are provided along the first adsorption path (112) so as to correspond to the corner of the edge (12) of the pouch case (10), the length direction (X-axis direction), and the width direction (Y-axis direction), thereby providing greater stability when transporting the pouch case (10).

[0104] Although FIGS. 8 and 9 illustrate a total of 16 second adsorption paths (113), this may vary depending on the size of the pouch case (10).

[0105] Fig. 10 is a perspective view of a pouch case transport device according to a fourth embodiment of the present invention, viewed from a lower side. Referring to Fig. 10, the pouch case transport device according to the fourth embodiment of the present invention is identical to the pouch case transport device according to the third embodiment except for the shape of the second adsorption path (113), and therefore, a description of the same configuration will be omitted.

[0106] The second adsorption path (113) according to the fourth embodiment may have a shape consisting of one or more polygons and one or more linear or curved lines so as to be in communication with the first adsorption path (112).

[0107] As an example, the second adsorption path (113) according to the fourth embodiment is a pattern shape composed of a plurality of squares having the same center and different diagonal lengths, and one or more lines crossing the center.

[0108] Of course, it is possible to have both the circular shape of the third embodiment and the square shape of the fourth embodiment, and it is obvious that the square can be changed to various shapes such as a triangle, pentagon, or hexagon.

[0109] Fig. 11 is a drawing showing a modified example of the first absorption path provided in the pouch case transport device of the present invention. Referring to Fig. 11, the first absorption path (112) according to the present invention may be configured in a wave shape or a zigzag shape with repeated peaks and valleys, or in a plurality of such shapes spaced at regular intervals.

[0110] Unlike the first embodiment, the first suction path (112) having a shape according to a modified example has an advantage in that the area in contact with the edge (12) of the pouch case (10) increases compared to a straight shape, thereby allowing the pouch case (10) to be suction-fixed more stably.

[0111] Of course, it is also possible to change the shape of the second adsorption path (113) according to the third and fourth embodiments described above to a circular or square shape according to a modified example.

[0112] Figure 12 is a flowchart for explaining a method of transporting a pouch case using a pouch case transport device according to the present invention.

[0113] A pouch case transport method according to the present invention may be configured to include a first step of positioning a contact portion on one surface of a pouch case, a second step of lowering the contact portion to contact the pouch case, a third step of adsorbing an edge of the pouch case, a fourth step of raising the contact portion to move the pouch case to a certain position, and a fifth step of stacking pouch cases.

[0114] First, the first step of positioning the sealing portion on one side of the pouch case is a step of positioning the sealing portion on the upper side of the pouch case, which is one side of the pouch case, in order to move the pouch case with the cup portion formed thereon to a predetermined position.

[0115] The second step of lowering the sealing portion and sealing it to the pouch case is the step of lowering the support bar connected to the sealing portion toward the pouch case and sealing the sealing portion and the pouch case.

[0116] Here, when the contact portion is provided with an auxiliary plate, when the contact portion is lowered, the auxiliary plate is seated in the cup portion of the pouch case.

[0117] The third step of adsorbing the edge of the pouch case is to operate the first pressure reducing pump to suck air while the first adsorption path is in close contact with the edge of the pouch case, so that the first air tube, the first air passage, and the first adsorption path are sequentially depressurized so that the edge of the pouch case is adsorbed and fixed to the first adsorption path.

[0118] Also, when the second pressure reducing pump is operated to suck air while the absorbent member is in close contact with the edge of the pouch case, the second air tube, the second air passage, and the absorbent member are sequentially depressurized so that the edge of the pouch case is absorbed and fixed to the absorbent member.

[0119] The fourth step of moving the pouch case to a predetermined position by raising the adhesive portion is a step of moving the pouch case to a predetermined position while the edge portion is adsorbed and fixed by the first adsorption path and / or adsorption member.

[0120] The fifth step of stacking the last pouch cases is a step of stacking the transported pouch cases at a predetermined position, which can be achieved by releasing the suction force of the first suction path and / or suction member when the sealing portion reaches the predetermined position.

[0121] Meanwhile, the aforementioned steps can be controlled by a separate control unit.
