Description

Technology Field

[0001] The present invention relates to a pouch case transfer device and a pouch case transfer method using the same. Specifically, it relates to a pouch case transfer device capable of stably transferring a pouch case without deformation of the pouch case when transferring a pouch case for a secondary battery, and a pouch case transfer method using the same. Background Technology

[0003] Recently, due to air pollution caused by the use of fossil fuels and the development of alternative energy sources resulting from energy depletion, the demand for secondary batteries capable of storing generated electrical energy is increasing.

[0004] Rechargeable batteries, which serve as an indispensable energy source for various electronic devices in modern society, are seeing increased capacity requirements due to the growing usage and complexity of mobile devices and the development of electric vehicles. While multiple battery cells are arranged in small devices to meet user demand, vehicles utilize battery modules that electrically connect multiple battery cells, or battery packs equipped with multiple such modules.

[0005] Meanwhile, during the process of manufacturing battery cells, formed pouch cases must be transported to a designated location, and to achieve this, many suction materials are used to suction and grip the edges of the pouch cases.

[0006] However, since depressurization and release are performed repeatedly, the adsorption members must be replaced at regular intervals, and since many adsorption members must be used, the initial cost of the pouch case transfer device is high.

[0007] FIG. 1 is a front view of a transfer device according to the prior art. As shown in FIG. 1, the sheet transfer device (9) according to the prior art includes a support (7) that supports the sheet, an adsorption member (40) that adheres to and adsorbs the sheet, a hollow shaft (41) connected to the adsorption member (40), and a support member (42) that supports the hollow shaft (41), and a suction hole is formed in the adsorption member (40).

[0008] A sheet transfer device (9) according to the prior art is provided with a suction hole in an adsorption member (40) that adheres to the sheet, and sucks in air to adsorb the sheet.

[0009] This adsorption structure can stably adsorb and transport the sheet, but the adsorption member (40) is positioned to correspond to all areas of the sheet, and this transport device still requires a large number of adsorption members (40).

[0010] Furthermore, if a large amount of suction material is used, there is a high possibility that the pouch case will be deformed due to the suction force. Prior art literature

[0036] Embodiments that enable a person skilled in the art to easily implement the present invention are described in detail below with reference to the attached drawings. However, in describing the operating principles of preferred embodiments of the present invention in detail, if it is determined that a specific description of related known functions or configurations may unnecessarily obscure the essence of the present invention, such detailed description will be omitted.

[0037] In addition, the same reference numerals are used for parts having similar functions and operations throughout the drawings. Throughout the specification, when a part is described as being connected to another part, this includes not only cases where they are directly connected, but also cases where they are indirectly connected with other elements in between. Furthermore, unless specifically stated otherwise, the inclusion of a certain component does not exclude other components but implies that additional components may be included.

[0039] Hereinafter, a pouch case transfer device according to the present invention and a pouch case transfer method using the same will be described with reference to the attached drawings.

[0040] FIG. 2 is a perspective view of a pouch case conveying device according to a first embodiment of the present invention viewed from one side of the upper direction, FIG. 3 is a perspective view of the pouch case conveying device shown in FIG. 2 viewed from one side of the lower direction, and FIG. 4 is a front view of the pouch case conveying device shown in FIG. 2 viewed from the bottom. FIG. 5 is a cross-sectional view taken along the direction I-I of FIG. 3, and FIG. 6 is a cross-sectional view showing a state in which a pouch case is adsorbed to the pouch case conveying device according to the first embodiment of the present invention.

[0041] Referring to FIGS. 2 to 6 together, the pouch case transfer device according to the first embodiment of the present invention may be configured to include a contact part (100), a support bar (200), and a pressure reducing member (300).

[0042] First, the pouch case (10) may 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.

[0043] 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.

[0044] The outer resin layer is located at the outermost part of the pouch case (10) and can be made of a heat-resistant polymer with excellent tensile strength, moisture resistance, and air permeability resistance to ensure heat resistance and chemical resistance while protecting the electrode assembly. For example, nylon or polyethylene terephthalate can be used, but is not limited thereto.

[0045] The metal layer in contact with the outer resin layer serves as a barrier layer that prevents moisture or various gases from penetrating into the battery from the outside, and a lightweight aluminum thin film with excellent formability can be used as a preferred material for this metal layer.

[0046] Furthermore, since the inner resin layer comes into direct contact with the electrode assembly, it must possess insulation and electrostatic resistance. Additionally, to ensure sealing from the outside, it must have sealing properties—specifically, excellent thermal bonding strength through the thermal bonding of the inner layers.

[0047] The material for this internal resin layer may be selected from, but is not limited to, polyolefin resins such as polypropylene, polyethylene, polyethylene acrylic acid, and polybutylene, polyurethane resins, and polyimide resins, which have excellent chemical resistance and good sealing properties; however, polypropylene is most preferred due to its excellent mechanical properties such as tensile strength, stiffness, surface hardness, and impact strength, as well as its chemical resistance.

[0048] 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.

[0049] In detail, the main plate (110) is in a roughly flat shape and is in close contact with the edge portion (12) of one side of the pouch case (10). At this time, so that most of the one side of the pouch case (10) is in close contact, the area of ​​the main plate (110) facing the one side of the pouch case (10) may be similar in size to the one side of the pouch case (10), for example, slightly smaller, the same, or slightly larger.

[0050] Also, when referring to FIG. 2, the upper surface corresponding to the other side of the main plate (110) is connected to the support bar (200), so the main plate (110) moves together with the support bar (200), and as a result, the pouch case (10) adsorbed to the main plate (110) moves to a predetermined position.

[0051] Meanwhile, the main plate (110) may be provided with a first air passage (111), a first adsorption channel (112), a second air passage (114), a storage groove (115), and an adsorption member (116) to adsorb and fix the edge portion (12) of the pouch case (10).

[0052] In detail, the first air passage (111) for the movement of the first air is formed in a shape that penetrates the interior of the main plate (110), with one side formed to face downward from the main plate (110) and communicating with the first adsorption channel (112), while the other side formed to face upward from the main plate (110) and exposed to the other side of the main plate (110).

[0053] The first adsorption channel (112) is configured to adsorb and fix the edge portion (12) of one side of the pouch case (10) by depressurization, and is formed in an inwardly recessed shape on the lower surface of the main plate (110), which is the surface facing the one side of the pouch case (10).

[0054] At this time, the first adsorption channel (112) is in communication with the first air passage (111) and is exposed toward one side of the edge portion (12) of the pouch case (10). It is preferable to have a pair of channels spaced apart by a certain distance so as to correspond to a pair of edges facing each other at the edge portion (12) of the pouch case (10), and it is more preferable to have two pairs spaced apart by a certain distance so as to correspond to two pairs of edges facing each other so as to more securely adsorb and fix the pouch case (10) (see FIG. 4).

[0055] Meanwhile, the first air passage (111) is formed in a structure that branches into multiple parts inside the main plate (110) and communicates with the first adsorption channel (112), and through this structure, all areas of the first adsorption channel (112) can be reduced in pressure almost simultaneously.

[0056] Although the first adsorption channel (112) is not shown in some directions (3 o'clock and 9 o'clock directions) in FIG. 4, the first adsorption channel (112) can be formed to be connected to each other as needed.

[0057] The vertical cross-section of the first adsorption channel (112) may be circular with a portion open toward the edge portion (12) of the pouch case (10) (see FIG. 5).

[0058] Next, the second air passage (114) for the movement of the second air is formed in a shape that penetrates the interior of the main plate (110), with one side formed to face downward from the main plate (110) and communicating with the adsorption member (116), while the other side formed to face upward from the main plate (110) and exposed to the upper surface, which is the other side of the main plate (110).

[0059] The adsorption member (116) is configured to adsorb and fix the edge portion (12) of one side of the pouch case (10) by depressurization, and is located on one side of the main plate (110), which is the surface facing the one side of the pouch case (10). Specifically, a storage groove (115) having a space of a certain size is formed on the lower surface of the main plate (110), and at least a portion of the adsorption member (116) is located in the storage groove (115) and faces the edge portion (12) of the pouch case (10).

[0060] 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). It is preferable that a plurality of adsorption members are provided spaced apart by a certain distance so as to correspond to a pair of edges facing each other in the edge portion (12) of the pouch case (10) in the overall length direction (X-axis direction), for example, a total of 4 to 6 members can be positioned, with 2 to 3 members in each overall length direction (X-axis direction).

[0061] Here, the adsorption member (116) may be an adsorption plate that generates adsorption force by depressurization and loses adsorption force when depressurization is released, and may be, for example, made of a flexible material and have a shape that widens toward the bottom.

[0062] Similar to the first air passage (111), the second air passage (114) is also formed in a structure that branches into multiple parts inside the main plate (110) and communicates with multiple adsorption members (116), and through this structure, all adsorption members (116) can be in a depressurized state almost simultaneously.

[0063] Although the edge portion (12) of the pouch case (10) can be fixed by adsorption using only the first adsorption channel (112) or the adsorption member (116), the edge portion (12) of the pouch case (10) can be fixed by adsorption more reliably when the first adsorption channel (112) and the adsorption member (116) are provided simultaneously, and furthermore, deformation of the pouch case (10) can be reduced by minimizing the use of the adsorption member (116).

[0064] Meanwhile, the auxiliary plate (120) has a flat shape with 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).

[0065] It is preferable that this auxiliary plate (120) be positioned near the center of one side of the main plate (110) so that it can be stored in the cup portion (11) of the pouch case (10) and be in close contact with one side of the cup portion (11), and it is more preferable that it have a thickness such that when in close contact with one side of the cup portion (11), the main plate (110) and the edge portion (12) of the pouch case (10) can be in close contact or slightly separated.

[0066] Although the drawing shows 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).

[0067] Of course, the auxiliary plate (120) can be omitted as needed. The auxiliary plate (120) can help reduce deformation of the shape of the cup portion (11) when the pouch case (10) is transported, but the auxiliary plate (120) can be omitted as needed.

[0068] Next, the support bar (200) may be in the shape of a bar having a certain length, and one side is connected to the other side, which is the upper surface of the contact portion (100), more specifically the main plate (110).

[0069] 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 designated position and then return to its original position, and since this operating principle corresponds to a known configuration, a detailed description will be omitted.

[0070] Also, in the drawing, the shape of the support bar (200) is shown as a square prism, but it can be changed to a cylindrical shape or any other shape.

[0071] 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) in a reduced pressure state at a certain level and may be configured to include a first air pipe (311) connected to the first air passage (111) exposed to the other side of the main plate (110), and a first pressure reducing pump (312) connected to the first air pipe (311).

[0072] Additionally, the second pressure reducing member (320) is configured to maintain the second air passage (114) in a reduced pressure state at a certain level and may include a second air pipe (321) connected to the second air passage (114) exposed to the other side of the main plate (110), and a second pressure reducing pump (322) connected to the second air pipe (321).

[0073] Here, the first air pipe (311) and the second air pipe (321) may be made of a material having flexibility and elasticity, and are not particularly limited as long as they are made of a material that does not affect the pressure reduction force when the first pressure reduction pump (312) and the second pressure reduction member (320) are each driven.

[0074] 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).

[0075] To briefly explain the operating principle of the aforementioned pressure reducing member (300), when the first pressure reducing pump (312) operates, it sucks in air from the first air pipe (311) and the first air passage (111) to maintain the first adsorption path (112) in a reduced pressure state at a certain level, and as a result, the edge portion (12) of the pouch case (10) can be adhered to and adsorbed.

[0076] Also, when the second pressure pump (322) operates, it sucks in air from the second air pipe (321) and the second air passage (114) to maintain the adsorption member (116) in a reduced pressure state at a certain level, and as a result, the edge portion (12) of the pouch case (10) can be adhered to and adsorbed.

[0077] Meanwhile, it is also possible to operate in a reduced pressure state by using a single pressure reducing member, for example, one air pipe equipped with an opening / closing valve and one pressure reducing pump, to suck in air from the first air passage and the second air passage together. However, in this case, it is practically impossible to individually adjust the pressure reduction force of the first air passage and the second air passage, and furthermore, if a malfunction occurs in the air pipe or the pressure reducing pump, the pouch case cannot be adsorbed at all; therefore, it is preferable to separately provide the first pressure reducing member (310) and the second pressure reducing member (320).

[0078] FIG. 7 is a cross-sectional view of a pouch case transfer device according to a second embodiment of the present invention. Referring to FIG. 7, the pouch case transfer device according to the second embodiment of the present invention is identical to the pouch case transfer device according to the first embodiment described in FIG. 2 to FIG. 6, except for the shape of the first adsorption channel (112), so the description of the identical configuration will be omitted.

[0079] In the pouch case transfer device according to the second embodiment, the vertical cross-section of the first adsorption channel (112) is in the shape of a rectangle with a portion open toward the edge portion (12) of the pouch case (10).

[0080] Although the vertical cross-section of the first adsorption channel (112) in FIG. 7 is shown as a square shape with a part open, the vertical cross-section can be formed as a polygon such as a triangle, pentagon, hexagon, and octagon with a part open.

[0081] FIG. 8 is a perspective view of a pouch case transfer device according to a third embodiment of the present invention viewed from one side of the lower side, and FIG. 9 is a front view of the pouch case transfer device shown in FIG. 8 viewed from the bottom.

[0082] Referring to FIGS. 8 and 9, the pouch case transfer device according to the third embodiment of the present invention is identical to the pouch case transfer device according to the first embodiment described in FIGS. 2 to 6, except that a second adsorption channel (113) is further provided on the main plate (110); therefore, the description of the identical configuration is omitted.

[0083] The pouch case transfer device according to the third embodiment is additionally provided with a second adsorption channel (113) having a certain pattern to communicate with the first adsorption channel (112).

[0084] At this time, the second adsorption channel (113) may have a shape consisting of one or more circular and one or more linear or curved shapes so as to be in communication with the first adsorption channel (112).

[0085] As an example, the second adsorption channel (113) according to the third embodiment may be a pattern shape consisting of a plurality of circles having the same center and different diameters, and one or more linear lines connecting the circles across the center.

[0086] To explain in more detail, the second adsorption channel (113) has a center located at the first adsorption channel (112) or at the point where the first adsorption channels (112) intersect each other, and one, more preferably two or more, circles are located around the center, and can also be configured with one or more linear lines crossing the center so as to connect them to each other.

[0087] Therefore, when the first air passage (111) and the first adsorption channel (112) are depressurized, the second adsorption channel (113) is also depressurized.

[0088] In particular, the second adsorption channel (113) has a pattern shape so that the adsorption area is wide, and is provided in multiple numbers along the first adsorption channel (112) so as to correspond to the corner of the edge portion (12) of the pouch case (10), the full length direction (X-axis direction), and the full width direction (Y-axis direction), thereby providing greater stability when transporting the pouch case (10).

[0089] Although FIGS. 8 and 9 show a total of 16 second adsorption channels (113), this can be changed depending on the size of the pouch case (10).

[0090] FIG. 10 is a perspective view of a pouch case transfer device according to a fourth embodiment of the present invention, viewed from one side of the lower side. Referring to FIG. 10, the pouch case transfer device according to the fourth embodiment of the present invention is identical to the pouch case transfer device according to the third embodiment except for the shape of the second adsorption channel (113), so the description of the identical configuration is omitted.

[0091] The second adsorption channel (113) according to the fourth embodiment may have a shape consisting of one or more polygons and one or more linear or curved shapes so as to be in communication with the first adsorption channel (112).

[0092] As an example, the second adsorption channel (113) according to the fourth embodiment is a pattern shape consisting of a plurality of squares with the same center and different diagonal lengths, and one or more linear lines crossing the center.

[0093] 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.

[0094] FIG. 11 is a drawing showing a modified example of a first adsorption channel provided in a pouch case transfer device of the present invention. Referring to FIG. 11, the first adsorption channel (112) according to the present invention may be composed of a wave shape, a zigzag shape with repeating peaks and valleys, and a plurality of these spaced apart at a certain interval.

[0095] Unlike the first embodiment, the first adsorption channel (112) having a shape according to the modified example has the advantage of being able to more stably adsorb and fix the pouch case (10) by increasing the contact area with the edge portion (12) of the pouch case (10) compared to the straight shape.

[0096] Of course, it is also possible for the circular or square shape of the second adsorption channel (113) according to the aforementioned third and fourth embodiments to be changed to a shape according to the modified example.

[0097] FIG. 12 is a flowchart illustrating a method of transferring a pouch case using a pouch case transfer device according to the present invention.

[0098] The pouch case transfer method according to the present invention may comprise a first step of positioning a contact portion on one surface of a pouch case, a second step of lowering the contact portion to make it adhere to the pouch case, a third step of adsorbing the edge portion 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 the pouch cases.

[0099] First, the first step of positioning the contact portion on one side of the pouch case is to position the contact portion on the upper part 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.

[0100] The second step of lowering the contact part to make it adhere to the pouch case is to lower the support bar connected to the contact part toward the pouch case to make the contact part and the pouch case adhere to each other.

[0101] Here, if an auxiliary plate is provided on the contact portion, when the contact portion descends, the auxiliary plate settles on the cup portion of the pouch case.

[0102] In the third step of adsorbing the edge portion of the pouch case, when the first adsorption channel is in close contact with the edge portion of the pouch case and the first depressurization pump is operated to suck in air, the first air pipe, the first air passage, and the first adsorption channel are sequentially depressurized, so that the edge portion of the pouch case is adsorbed and fixed to the first adsorption channel.

[0103] Additionally, when the second depressurization pump is operated to suck in air while the adsorption member is in close contact with the edge of the pouch case, the second air pipe, the second air passage, and the adsorption member are sequentially depressurized, so that the edge of the pouch case is adsorbed and fixed to the adsorption member.

[0104] The fourth step of raising the contact portion to move the pouch case to a certain position is a step of moving it to a set position while the edge portion is adsorbed and fixed by the first adsorption channel and / or adsorption member.

[0105] The fifth step of stacking the last pouch case is a step of stacking the transported pouch case at a predetermined position, which can be achieved by releasing the adsorption force of the first adsorption channel and / or adsorption member when the contact portion reaches the predetermined position.

[0106] Meanwhile, the aforementioned steps can be controlled by a separate control unit.
