Description

Technical Field

[0001] This application claims priority to Korean Patent Application No. 10-2024-0072428, filed on June 3, 2024, the disclosure of which is incorporated herein by reference in its entirety.

[0002] This invention relates to a bag housing conveying device and a bag housing conveying method using the same, and more specifically, to a bag housing conveying device and a bag housing conveying method using the same capable of stably conveying bag housings for secondary batteries without deformation of the bag housings during conveying. Background Technology

[0003] With the recent development of alternative energy sources due to gas pollution and energy depletion caused by the use of fossil fuels, the demand for secondary batteries capable of storing the generated electricity has increased.

[0004] Due to the increased use and complexity of mobile devices, as well as the development of electric vehicles, the required capacity of secondary batteries for powering various electronic devices that are unavoidable in modern society has increased. To meet user needs, multiple battery cells are incorporated into small devices, while battery modules comprising multiple battery cells electrically connected to each other, or battery packs comprising multiple battery modules, are used in vehicles and other applications.

[0005] Furthermore, in the process of manufacturing battery cells, the formed bag shells must be conveyed to a predetermined position. For this purpose, numerous adsorption components are used to adsorb and grip the edges of the bag shells.

[0006] However, the bag housing conveying equipment has a high initial cost due to the need to replace the adsorption components at predetermined intervals because of repeated decompression and decompression, and because of the use of many adsorption components.

[0007] Figure 1 This is the front view of a conventional transmission device. (Example) Figure 1 As shown, a conventional sheet conveying device 9 includes: a support member 7 configured to support a sheet; an adsorption member 40 configured to adsorb the sheet in close contact with the sheet; a hollow shaft 41 connected to the adsorption member 40; and a support portion 42 configured to support the hollow shaft 41, wherein adsorption holes are formed in the adsorption member 40.

[0008] In a conventional sheet conveying device 9, an adsorption hole is formed in an adsorption member 40 configured to be in close contact with the sheet, so as to adsorb the sheet by drawing in gas.

[0009] In this adsorption structure, the sheet can be stably adsorbed and conveyed; however, the adsorption members 40 are positioned to correspond to all areas of the sheet. Therefore, the conveying device still requires a large number of adsorption members 40.

[0010] In addition, when multiple adsorption components are used, the bag shell is likely to deform due to the adsorption force.

[0047] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, enabling those skilled in the art to readily implement these preferred embodiments. However, in describing the operational principles of the preferred embodiments of the present invention, detailed descriptions of known functions and configurations incorporated herein will be omitted where such descriptions might obscure the subject matter of the invention.

[0048] Furthermore, the same reference numerals will be used throughout the accompanying drawings to refer to parts that perform similar functions or operations. Throughout the specification, where a part is referred to as being connected to another part, this means not only that one part can be directly connected to another part, but also that one part can be indirectly connected to another part via yet another part. Additionally, including an element does not imply the exclusion of other elements, but rather means that these elements may be further included unless otherwise specified.

[0049] In the following description, a bag housing conveying device according to the present invention and a bag housing conveying method using the same will be described with reference to the accompanying drawings.

[0050] Figure 2 This is a perspective view of the bag housing conveying device according to the first embodiment of the present invention, viewed from above in one direction. Figure 3 When viewed from below in one direction Figure 2 The diagram shows a perspective view of the bag housing conveying device, and Figure 4 When viewed from below Figure 2 The image shows a front view of the bag housing conveying device. Additionally... Figure 5 It is along Figure 3 A sectional view taken from line II, and Figure 6 This is a cross-sectional view showing the state in which a bag housing is adsorbed by a bag housing conveying device according to a first embodiment of the present invention.

[0051] Reference Figures 2 to 6 The bag housing conveying device according to the first embodiment of the present invention may include a tight contact unit 100, a support rod 200 and a pressure reducing member 300.

[0052] First, the bag housing 10 may include a cup portion 11 and an edge portion 12, the cup portion 11 defining a specific space portion configured to receive an electrode assembly and an electrolyte solution, and the edge portion 12 extending outward from the cup portion 11 for sealing.

[0053] Here, the bag shell 10 is made of a laminate comprising an outer resin layer, a metal layer and an inner resin layer, wherein the laminate is shaped to form a cup portion.

[0054] The outermost resin layer located on the outermost side of the bag housing 10 can be made of a heat-resistant polymer exhibiting excellent tensile strength, moisture permeability resistance, and gas permeability resistance, so that the outer resin layer exhibits high heat resistance and chemical resistance while protecting the electrode assembly. As an example, the outer resin layer can be made of nylon or polyethylene terephthalate; however, the invention is not limited thereto.

[0055] The metal layer that contacts the outer resin layer corresponds to a barrier layer configured to prevent moisture or various gases from penetrating into the battery from the outside. Lightweight and easily formable aluminum thin film is a preferred material for the metal layer.

[0056] The inner resin layer is in direct contact with the electrode assembly, therefore it needs to exhibit high insulation and high electrolytic resistance. Additionally, the inner resin layer needs to exhibit high sealing performance to airtightly isolate the bag housing from the outside; that is, the thermally bonded seal between the inner layers needs to exhibit excellent thermal bonding strength.

[0057] The inner resin layer may be made of a material selected from polyolefin-based resins (such as polypropylene, polyethylene, polyethylene acrylic or polybutene), polyurethane resins and polyimide resins that exhibit excellent chemical resistance and high sealing performance; however, the invention is not limited thereto, and polypropylene that exhibits excellent mechanical properties (such as tensile strength, rigidity, surface hardness and impact resistance) and excellent chemical resistance is most preferred.

[0058] The close contact unit 100 for the conveying bag housing 10 may include a main board 110 and an auxiliary board 120. The main board 110 is a flat plate with a specific area, and the auxiliary board 120 is disposed at the center of one surface of the main board 110 so as to protrude a specific length from the main board 110 as needed.

[0059] Specifically, the main board 110, which is generally flat, can be in close contact with the edge 12 of one surface of the bag housing 10. In this case, the area of ​​the main board 110 facing the one surface of the bag housing 10 can be similar to the area of ​​the one surface of the bag housing 10, for example, slightly smaller, equal to or slightly larger than the area of ​​the one surface of the bag housing, so that most of the one surface of the bag housing 10 is in close contact with the main board.

[0060] Additionally, refer to Figure 2 The upper surface of the motherboard 110 (which is the other surface of the motherboard 110) is connected to the support rod 200, so that the motherboard 110 can move via the support rod 200, thereby moving the bag shell 10 adsorbed by the motherboard 110 to a predetermined position.

[0061] In addition, the main board 110 may be provided with a first gas channel 111, a first adsorption channel 112, a second gas channel 114, a receiving recess 115, and an adsorption member 116, so as to adsorb and fix the edge portion 12 of the bag shell 10.

[0062] Specifically, a first gas channel 111 for the movement of the first gas is formed through the interior of the motherboard 110, wherein one side of the first gas channel is formed facing the lower part of the motherboard 110 and communicating with the first adsorption channel 112, and the other side of the first gas channel is formed facing the upper part of the motherboard 110 and exposed to the other surface of the motherboard 110.

[0063] The first adsorption channel 112 is configured to adsorb and fix the edge portion 12 of one surface of the bag housing 10 by depressurization, and is formed in an inwardly recessed shape in the lower surface of the main board 110 facing the one surface of the bag housing 10.

[0064] In this configuration, the first adsorption channel 112 communicates with the first gas channel 111 and is also exposed toward a surface of the edge portion 12 of the bag housing 10. Preferably, the first adsorption channels are arranged in a pair spaced apart by a specific distance to correspond to a pair of edges facing each other at the edge portion 12 of the bag housing 10. More preferably, the first adsorption channels are arranged in two pairs spaced apart by a specific distance to correspond to the two pairs of edges facing each other, in order to more reliably adsorb and fix the bag housing 10 (see [link]). Figure 4 ).

[0065] Furthermore, the first gas channel 111 is divided into multiple branches in the main board 110 to communicate with the first adsorption channel 112. In this structure, all regions of the first adsorption channel 112 can be depressurized approximately simultaneously.

[0066] Although Figure 4 It is shown that the first adsorption channel 112 is not provided in some directions (3 o'clock direction and 9 o'clock direction), but the first adsorption channel 112 can be formed to be connected to each other as needed.

[0067] The vertical cross-section of the first adsorption channel 112 may be circular, with a portion of it opening toward the edge 12 of the bag housing 10 (see [reference]). Figure 5 ).

[0068] A second gas channel 114 for the movement of the second gas is formed through the interior of the motherboard 110. One side of the second gas channel is formed to face the lower part of the motherboard 110 and communicate with the adsorption member 116, while the other side of the second gas channel is formed to face the upper part of the motherboard 110 and is exposed to the upper surface of the motherboard 110 (which is the other surface of the motherboard).

[0069] The adsorption member 116 is configured to adsorb and fix the edge portion 12 of one surface of the bag housing 10 by depressurization, and is located on a surface of the main board 110 facing that one surface of the bag housing 10. Specifically, a receiving recess 115 is formed in the lower surface of the main board 110 (which is the one surface of the main board) in a spatially defined manner, and at least a portion of the adsorption member 116 is located within the receiving recess 115 when facing the edge portion 12 of the bag housing 10.

[0070] In this configuration, the adsorption members 116 are located between the edge portion 12 facing the first gas channel 111 and the cup portion 11, preferably arranged in a manner corresponding to a pair of edges positioned facing each other along the overall length direction (X-axis direction) at the edge portion 12 of the bag housing 10, and spaced apart from each other by a specific distance. For example, two to three adsorption members can be positioned in each overall length direction (X-axis direction), thus allowing for a total of four to six adsorption members to be positioned.

[0071] Here, the adsorption member 116 can be an adsorption plate that generates adsorption force by depressurization and loses adsorption force when the depressurization is released. For example, the adsorption member can be made of a flexible material and shaped to have a width that gradually increases towards its bottom.

[0072] Similar to the first gas channel 111, the second gas channel 114 is also divided into multiple branches in the main board 110 to communicate with multiple adsorption components 116. In this structure, all adsorption components 116 can be depressurized at approximately the same time.

[0073] The edge portion 12 of the bag housing 10 can be adsorbed and fixed using only one of the first adsorption channel 112 and the adsorption member 116. However, when the first adsorption channel 112 and the adsorption member 116 are provided simultaneously, the edge portion 12 of the bag housing 10 can be adsorbed and fixed more reliably, and in addition, the use of the adsorption member 116 can be minimized, thereby preventing deformation of the bag housing 10.

[0074] Furthermore, the auxiliary board 120 is a flat plate with a smaller area than the main board 110, and can be formed on one surface of the main board 110 in a downward protruding manner.

[0075] Preferably, the auxiliary plate 120 is located near the center of one surface of the main plate 110, such that the auxiliary plate can be accommodated in the cup portion 11 of the bag housing 10 and in close contact with one surface of the cup portion 11. More preferably, the auxiliary plate has a thickness such that when the auxiliary plate is in close contact with one surface of the cup portion 11, the edges 12 of the main plate 110 and the bag housing 10 can be in close contact with each other or slightly spaced apart from each other.

[0076] Although the accompanying drawings show two auxiliary plates 120, it is obvious that the position and number of auxiliary plates 120 can be changed according to the shape and number of cup portions 11 of the bag housing 10.

[0077] Of course, the auxiliary plate 120 can be omitted if necessary. The auxiliary plate 120 can help reduce the deformation of the cup portion 11 during the transfer of the bag housing 10, but it can be omitted if necessary.

[0078] The support rod 200 may be in the shape of a rod with a specific length, wherein one side of the support rod is connected to the close contact unit 100, and more specifically to another surface of the motherboard 110 (which is the upper surface of the motherboard).

[0079] Although not shown in the figure, the support rod 200 can be connected to a robotic arm, a moving track, etc., and can be controlled to move to a predetermined position and then return to its original position. Its operating principle is known in the art, therefore a detailed description will be omitted.

[0080] Furthermore, although the attached drawings show that the support rod 200 has a quadrilateral prism shape, the shape of the support rod can be changed to any other shape, such as a cylindrical shape.

[0081] Next, the pressure-reducing component 300 will be described. The pressure-reducing component 300 includes a first pressure-reducing component 310 and a second pressure-reducing component 320. The first pressure-reducing component 310 is configured to maintain a first gas passage 111 at a specific pressure-reducing level and may include a first gas conduit 311 and a first pressure-reducing pump 312, the first gas conduit 311 being connected to the first gas passage 111 exposed on another surface of the main board 110, and the first pressure-reducing pump 312 being connected to the first gas conduit 311.

[0082] Additionally, the second pressure-reducing component 320 is configured to maintain the second gas passage 114 at a specific pressure-reducing level, and may include a second gas conduit 321 and a second pressure-reducing pump 322, the second gas conduit 321 being connected to the second gas passage 114 exposed on another surface of the motherboard 110, and the second pressure-reducing pump 322 being connected to the second gas conduit 321.

[0083] Here, each of the first gas pipe 311 and the second gas pipe 321 may be made of a flexible and stretchable material, and there are no particular restrictions on the material used for each of the first gas pipe and the second gas pipe, as long as it does not affect the pressure reduction of each of the first pressure reducing pump 312 and the second pressure reducing member 320 during operation.

[0084] Reference numeral V1 indicates a first on / off valve located in the first gas conduit 311, and reference numeral V2 indicates a second valve located in the second gas conduit 321.

[0085] The operating principle of the pressure-reducing component 300 will be briefly described. When the first pressure-reducing pump 312 is operated, the first pressure-reducing pump draws gas from the first gas pipe 311 and the first gas passage 111 to maintain the first adsorption passage 112 at a specific pressure reduction level, thereby allowing the edge portion 12 of the bag shell 10 to be adsorbed in a manner that brings it into close contact with the first adsorption passage.

[0086] In addition, when the second pressure reducing pump 322 is operated, the second pressure reducing pump draws gas from the second gas pipe 321 and the second gas passage 114 to maintain the adsorption member 116 at a specific pressure reduction level, thereby allowing the edge portion 12 of the bag shell 10 to be adsorbed in a manner that is in close contact with the adsorption member.

[0087] Furthermore, pressure reduction can be controlled by using a pressure-reducing component (e.g., a gas pipe with an on / off valve and a pressure-reducing pump) to draw gas from both the first and second gas channels. However, in this case, it is practically impossible to adjust the pressure reduction of the first and second gas channels independently, and furthermore, the bag housing cannot be adsorbed at all when the gas pipe or pressure-reducing pump malfunctions. Therefore, it is preferable to provide the first pressure-reducing component 310 and the second pressure-reducing component 320 separately.

[0088] Figure 7 This is a cross-sectional view of a bag housing conveying device according to a second embodiment of the present invention. (Refer to...) Figure 7 Except for the shape of the first adsorption channel 112, the bag housing conveying device according to the second embodiment of the present invention is similar to the reference. Figures 2 to 6 The bag housing conveying device described according to the first embodiment is the same, so the description of the same configuration will be omitted.

[0089] In the bag housing conveying device according to the second embodiment, the vertical cross-section of the first adsorption channel 112 has a quadrilateral shape that opens toward the edge portion 12 of the bag housing 10.

[0090] Although Figure 7 In the diagram, the vertical cross-section of the first adsorption channel 112 is shown as a quadrilateral shape with a portion of its opening, but the vertical cross-section can be formed as a polygonal shape with a portion of its opening, such as a triangular shape, a pentagonal shape, a hexagonal shape, or an octagonal shape.

[0091] Figure 8 This is a perspective view of a bag housing conveying device according to a third embodiment of the present invention, viewed from below in one direction. Figure 9 When viewed from below Figure 8 The front view of the bag housing conveying device shown.

[0092] Reference Figure 8 and Figure 9 In addition to further providing a second adsorption channel 113 on the main board 110, the bag housing conveying device according to the third embodiment of the present invention is similar to the reference. Figures 2 to 6 The bag housing conveying device described according to the first embodiment is the same, so the description of the same configuration will be omitted.

[0093] In the bag housing conveying device according to the third embodiment, a second adsorption channel 113 is further provided, which has a specific pattern so as to communicate with the first adsorption channel 112.

[0094] In this case, the second adsorption channel 113 may have a shape including one or more circles and one or more straight lines or curves, so as to communicate with the first adsorption channel 112.

[0095] In the example, the second adsorption channel 113 according to the third embodiment may have a pattern shape comprising a plurality of circles having the same center and different diameters, and one or more straight lines connecting the circles to each other as they pass through the center of the circles.

[0096] More specifically, the center of the second adsorption channel 113 may be located within the first adsorption channel 112 or in the area where it intersects with the first adsorption channel 112. A circle, more preferably two or more circles, may be located outside the center, and one or more straight lines may pass through the center of these circles to connect them to each other.

[0097] Therefore, when the first gas channel 111 and the first adsorption channel 112 are depressurized, the second adsorption channel 113 is also depressurized.

[0098] In particular, because the second adsorption channel 113 has a patterned shape, the adsorption area of ​​the second adsorption channel 113 is large. Furthermore, multiple second adsorption channels are arranged along the first adsorption channel 112 in such a way that they correspond to the corners of the edge portion 12 of the bag housing 10, the portion of the edge portion of the bag housing in the overall length direction (X-axis direction), and the portion of the edge portion of the bag housing in the overall width direction (Y-axis direction). This can further improve the stability of the bag housing 10 during transport.

[0099] Although Figure 8 and Figure 9 A total of 16 second adsorption channels 113 are shown, but the number of second adsorption channels can vary depending on the size of the bag housing 10.

[0100] Figure 10 This is a perspective view of a bag housing conveying device according to a fourth embodiment of the present invention, viewed from below in one direction. (Refer to...) Figure 10 Except for the shape of the second adsorption channel 113, the bag housing conveying device according to the fourth embodiment of the present invention is the same as the bag housing conveying device according to the third embodiment, so the description of the same configuration will be omitted.

[0101] According to the fourth embodiment, the second adsorption channel 113 may have a shape including one or more polygons and one or more straight lines or curves, so as to communicate with the first adsorption channel 112.

[0102] In one example, the second adsorption channel 113 according to the fourth embodiment may have a pattern shape comprising a plurality of quadrilaterals having the same center and different diagonal lengths, and one or more straight lines passing through the center of the quadrilaterals.

[0103] Of course, it is obvious that the circular shape of the third embodiment and the quadrilateral shape of the fourth embodiment can be provided together, and various other shapes (such as triangles, pentagons or hexagons) can be used instead of the quadrilateral shape.

[0104] Figure 11 This is a diagram illustrating a modified example of the first adsorption channel provided in the bag housing conveying device according to the present invention. (Refer to...) Figure 11 According to the invention, the first adsorption channel 112 may have a wave shape, a serrated shape with repeating peaks and valleys, or a plurality of wave shapes or serrated shapes spaced apart from each other by a predetermined distance.

[0105] Unlike the first embodiment, the advantage of having a first adsorption channel 112 with a shape according to the modified example is that, compared with a straight shape, the contact area between the first adsorption channel and the edge portion 12 of the bag shell 10 is increased, thereby allowing for more reliable adsorption and fixation of the bag shell 10.

[0106] Of course, the circular or quadrilateral shape of the second adsorption channel 113 in each of the third and fourth embodiments described above can be changed to the shape according to the modified example.

[0107] Figure 12 This is a flowchart illustrating a bag housing conveying method using a bag housing conveying device according to the present invention.

[0108] The bag housing conveying method according to the present invention may include: a first step of positioning a tight contact unit above a surface of the bag housing; a second step of moving the tight contact unit downward to make tight contact with the bag housing; a third step of adsorbing the edge of the bag housing; a fourth step of moving the tight contact unit upward and moving the bag housing to a specific position; and a fifth step of stacking the bag housings.

[0109] First, the first step of positioning the tight contact unit above a surface of the bag housing is to position the tight contact unit above a surface of the bag housing (i.e., the upper surface of the bag housing in which the cup portion is formed) in order to move the bag housing to a predetermined position.

[0110] The second step of moving the tight contact unit downward to make tight contact with the bag housing is to move the support rod connected to the tight contact unit downward in the direction toward the bag housing so that the tight contact unit makes tight contact with the bag housing.

[0111] If the tight contact unit is provided with an auxiliary plate, the auxiliary plate is placed in the cup part of the bag shell when the tight contact unit moves downward.

[0112] In the third step at the edge of the adsorption bag shell, with the first adsorption channel in close contact with the edge of the bag shell, the first pressure reducing pump is operated to draw gas, so that the first gas pipe, the first gas channel and the first adsorption channel are depressurized in sequence, thereby adsorbing and fixing the edge of the bag shell through the first adsorption channel.

[0113] In addition, with the adsorption component in close contact with the edge of the bag shell, the second pressure reducing pump is operated to draw in gas, causing the second gas pipe, the second gas channel and the adsorption component to be depressurized in sequence, thereby adsorbing and fixing the edge of the bag shell by the adsorption component.

[0114] The fourth step, which involves moving the tight contact unit upward and the bag housing to a specific position, is to move the bag housing to a predetermined position while adsorbing and fixing the edges through the first adsorption channel and / or adsorption member.

[0115] The fifth step of stacking the bag shells is to stack the conveyed bag shells in a predetermined position, which can be achieved by releasing the adsorption force of the first adsorption channel and / or adsorption member when the close contact unit reaches the predetermined position.

[0116] The above steps can be controlled by a separate controller.

[0117] Those skilled in the art will understand that, based on the above description, various applications and modifications can be made within the scope of this invention.
