Description

Technical Field

[0001] The present disclosure relates to a device for transporting objects, in particular battery cells or components constituting battery cells.

[0002] This application is based on and claims the benefit of priority from Korean Patent Application No. 10-2023-0119927 filed on September 8, 2023, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference. Background Art

[0003] Secondary batteries, which have high applicability depending on the product group and electrical characteristics such as high energy density, are generally used not only in portable devices but also in electric vehicles (EVs) or hybrid electric vehicles (HEVs) driven by power supplies. Such secondary batteries have the major advantage of significantly reducing the use of fossil fuels and do not generate byproducts from the use of energy, and are therefore attracting attention as a new energy source that improves eco-friendliness and energy efficiency.

[0004] Currently widely used secondary batteries include lithium-ion batteries, lithium polymer batteries, nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, etc. The operating voltage of a unit secondary battery cell (i.e., a unit battery cell) is about 2.5V to 4.5V. Therefore, if a higher output voltage is required, a plurality of battery cells can be connected in series to form a battery pack. In addition, according to the required charge and discharge capacity of the battery pack, a plurality of battery cells can be connected in parallel to form a battery pack. Therefore, the number of battery cells included in the battery pack can be set differently according to the required output voltage and / or the required charge and discharge capacity.

[0005] Furthermore, in the manufacturing process of such secondary batteries, rotating equipment is used in various steps. For example, this may include conveying devices for transferring battery cells or components that make up battery cells from one process to the next. In this rotating equipment structure, in the tray sections where components are transferred and handled, corresponding operations are performed by sending and receiving signals to solenoid valves based on the vacuum and release.

[0006] However, due to the characteristics of high-speed rotating equipment, there was a problem with aligning the timing of vacuum suction and release when handling and transferring components. Specifically, this caused problems such as non-operation due to delays in vacuum suction and release. Furthermore, the need for electrical wiring based on the number of components to be transferred led to an increase in the number of electrical component management points and increased equipment costs. Summary of the Invention

[0043] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Before the description, it should be understood that the terms used in the specification and the appended claims should not be interpreted as limited to the general and dictionary meanings, but should be interpreted according to the meanings and concepts corresponding to the technical aspects of the present disclosure based on the principle of allowing the inventor to appropriately define the terms for the best interpretation.

[0044] Therefore, the embodiments described in this specification and the configurations shown in the drawings are only some of the most preferred embodiments of the present disclosure and are not intended to fully represent the technical aspects of the present disclosure. Therefore, it should be understood that various equivalents and modifications may be made thereto when this application is filed.

[0045] Additionally, to help understand the present disclosure, the drawings are not drawn to scale, and the sizes of some components may be exaggerated.

[0046] Traditionally, rotating equipment is used in various processes during the manufacturing of secondary batteries. For example, this can include conveying devices for transferring battery cells or components that make up battery cells from one process to the next. In this rotating equipment structure, in the tray sections where components are transferred and handled, signals are sent and received to solenoid valves based on vacuum and release, executing corresponding operations.

[0047] However, due to the characteristics of high-speed rotating equipment, there was a problem with aligning the timing of vacuum suction and release when handling and transferring components. Specifically, this caused problems such as non-operation due to delays in vacuum suction and release. Furthermore, the need for electrical wiring based on the number of components to be transferred led to an increase in the number of electrical component management points and increased equipment costs.

[0048] More specifically, in conventional rotary equipment, the conveyor system forms a vacuum chamber for each disk head, and a solenoid valve is installed in each vacuum chamber to achieve and release the vacuum. For example, if there are six disk heads, six vacuum chambers should be formed and equipped with six solenoid valves. This method of controlling the vacuum by installing a valve for each head not only has cost issues, but also increases the number of equipment management points due to the excessive number of components that make up the conveyor system (such as solenoid valves and electrical wiring).

[0049] The present disclosure aims to solve the above problems. Figures 1 to 10 The conveying device 1 for achieving the above-mentioned objects will be described in detail.

[0050] Figure 1 is a diagram for describing a conveying device 1 according to an embodiment of the present disclosure, Figure 2 yes Figure 1 Exploded three-dimensional diagram.

[0051] Reference Figure 1 and Figure 2 , the conveying device 1 according to an embodiment of the present disclosure includes a first tray 10 , a second tray 20 , and a washer 30 .

[0052] More specifically, the conveying device 1 may include: a first disk 10, which has a disk shape and is configured to rotate based on the central axis C of the disk; a second disk 20, which is arranged above the first disk 10 and has a disk shape; and a gasket 30, which is inserted between the first disk 10 and the second disk 20.

[0053] The gasket 30 can ensure airtightness between the first tray 10 and the second tray 20. The gasket 30 can be configured to generate vacuum, release vacuum, or blow air at a predetermined position. The object to be transferred can be configured to be adsorbed and desorbed on the first tray 10.

[0054] This structure can reduce the number of valves required for each location requiring vacuum and vacuum release, as in the prior art. This reduces equipment costs. Furthermore, the consistency of the timing of takeover and handover, which is matched by the valve electrical signals, can be improved. In other words, according to the present disclosure, the consistency of takeover and handover timing can be improved through improvements to the mechanical structure, while also reducing the number of valves required for adsorption and desorption of the object being transferred, thereby reducing unnecessary wiring work and complexity.

[0055] Preferably, the second disk 20 and the washer 30 may not rotate. That is, it may be configured so that only the first disk 10 rotates, and the second disk 20 and the washer 30 do not rotate.

[0056] According to this structure, only the first tray 10 that transfers the object to be transferred can rotate, thereby transferring the object, and the second tray 20 and the gasket 30 that do not directly contact the object to be transferred can remain fixed, thereby improving the efficiency of the device and minimizing unnecessary operations and movements.

[0057] Figure 3 is used to describe Figure 1 FIG. 1 shows a first tray 10 included in the conveying device 1 , Figure 4 yes Figure 3 A side view of the first tray 10 is shown.

[0058] In one aspect of the present disclosure, the first tray 10 may have a plurality of suction holes H along the circumferential direction.

[0059] For example, refer to Figure 3 and Figure 4 The first disk 10 may have a substantially circular disk shape. In this case, the first disk 10 may have a plurality of through-circuits 11 extending parallel to the central axis C. In other words, the through-circuits 11 may be configured as tubular spaces extending through the upper and lower surfaces of the first disk 10. Multiple through-circuits 11 may be arranged circumferentially around the central axis C.

[0060] In addition, refer to Figure 3 and Figure 4 The first disk 10 may have a plurality of adsorption holes H along the circumferential direction. The adsorption holes H may be provided on the side surface of the first disk 10. A plurality of adsorption holes H may also be provided on the side surface of the first disk 10. The adsorption holes H may be configured to connect to the through-circuit 11. In other words, the adsorption holes H may be configured as a tubular passage from the outer surface of the first disk 10 to the through-circuit 11. Thus, the adsorption holes H and the through-circuit 11 may communicate with each other.

[0061] In another aspect of the present disclosure, there may be multiple adsorption holes H physically connected to one through-line 11. For example, referring to Figure 3 , there can be three adsorption holes H connected to a through line 11. This will be referred to later Figure 7 and Figure 8 Describe in more detail.

[0062] In another aspect of the present disclosure, the adsorption holes H can be configured to adsorb and desorb the object to be transported. That is, according to the present disclosure, by controlling the inflow and outflow of gas through the through-line 11 and the adsorption holes H, the adsorption and desorption of the object to be transported in contact with the adsorption holes H can be controlled.

[0063] For example, refer to Figure 4, the object to be conveyed may be a tape T. The tape T may be a tape T that surrounds the outer surface of the battery cell. In particular, the tape T may be a tape T that surrounds the side of a cylindrical battery cell. That is, the side surface of the cylindrical battery cell is made of a conductor, usually having a negative pole or a positive pole, and by covering the side surface of the battery cell with the tape T, the conductivity of the side surface of the battery cell can be blocked. Before performing a process of surrounding the outer surface of the battery cell with the tape T in this manner, a conveyor for guiding the tape T to the process may be required. The present disclosure may be a conveying device 1 for handing over such a tape T. Referring to Figure 4 A plurality of suction holes H are provided on the side surface of the first tray 10, and the tape T can be attached and / or detached at positions facing the plurality of suction holes H. In other words, the tape T can be attached to the side surface of the first tray 10 at predetermined points, and can be detached from the side surface of the first tray 10 at predetermined points. According to the present disclosure, such attachment and detachment points can be fixed at specific positions, and the control accuracy of the attachment and detachment points can be improved during the process.

[0064] Figure 5 is used to describe Figure 1 FIG. 1 is a diagram of a gasket 30 included in the conveying device 1 .

[0065] In another aspect of the present disclosure, the gasket 30 may include a first slot S1 and a second slot S2. More specifically, the gasket 30 may include at least one first slot S1 and one second slot S2, respectively, which are configured to pass through in a direction parallel to the central axis C and have a predetermined space.

[0066] For example, refer to Figure 5 , the gasket 30 may include a plurality of first slots S1 and a plurality of second slots S2 passing through in a direction parallel to the central axis C. Here, the first slot S1 may be a vacuum slot, and the second slot S2 may be an air blowing slot. For example, a vacuum may be generated at a position corresponding to the first slot S1, and gas may be exhausted at a position corresponding to the second slot S2. Here, the first slot S1 and the second slot S2 may be configured to communicate with the through-circuit 11 of the first disk 10. That is, the gasket 30 may be located above the first disk 10, and the first slot S1 or the second slot S2 may be located above the plurality of through-circuit 11 provided on the first disk 10. Therefore, the first slot S1, the through-circuit 11, and the adsorption hole H may be configured to allow gas communication with each other. Similarly, the second slot S2, the through-circuit 11, and the adsorption hole H may also be configured to allow gas communication with each other.

[0067] According to this structure, a vacuum is generated in the suction holes H at the positions corresponding to the first slots S1, so that the tape T in contact with the suction holes H at the positions corresponding to the first slots S1 can be effectively sucked. In addition, air blowing is generated in the suction holes H at the positions corresponding to the second slots S2, so that the tape T in contact with the suction holes H at the positions corresponding to the second slots S2 can be effectively detached. In other words, according to the present disclosure, it is possible to control the vacuum and vacuum release at specific areas and / or points.

[0068] In yet another embodiment of the present disclosure, the first groove S1 and the second groove S2 may have an arc shape formed to have a predetermined angle based on the central axis C.

[0069] For example, refer to Figure 5 , the first groove S1 may have an arc shape having a predetermined angle based on the central axis C. In this case, when the predetermined angle becomes very small, the arc shape may become a circular shape. For example, referring to Figure 5 , the second groove S2 may have such a circular shape.

[0070] This structure allows for various configurations of the shapes of the first and second slots S1, S2. Consequently, in some cases, the timing of vacuum and air blowing can be configured in various ways. For example, if the length of the tape T to be attached changes, the positions and angles of the first and second slots S1, S2 can be altered to match the changed length, thereby enabling the attachment and detachment of the tape T.

[0071] In another embodiment of the present disclosure, the gasket 30 may have an annular shape, for example. However, the shape of the gasket 30 is not limited thereto, and any shape that can be interposed between the first plate 10 and the second plate 20 is considered to be within the scope of the present disclosure. For example, the gasket 30 may have a disc shape.

[0072] Figure 6 is used to describe Figure 1 FIG. 1 is a diagram of a second tray 20 included in the conveying device 1 .

[0073] In another aspect of the present disclosure, the second tray 20 may include a first accessory F1 and a second accessory F2. More specifically, the second tray 20 may include a first accessory F1 connected to a vacuum device and a second accessory F2 connected to an air blowing device.

[0074] According to this structure, the first fitting F1 and the second fitting F2 can serve as channels for gas inflow and outflow. Specifically, the first fitting F1 can be connected to a vacuum device and, in this case, may also include a connecting pipe or the like. Therefore, when the vacuum device is operating, gas can flow through the first fitting F1 toward the exterior of the first fitting F1. Similarly, the second fitting F2 can be connected to a blower device and, in this case, may also include a connecting pipe or the like. Therefore, when the blower device is operating, gas can flow from the exterior of the second fitting F2 to the interior of the second fitting F2.

[0075] Figure 7 It is intercepted at a predetermined angle Figure 1 A longitudinal sectional view of the conveying device 1, Figure 8 is with Figure 7 Taken from different angles Figure 1 A longitudinal sectional view of the conveying device 1 is shown.

[0076] Reference Figure 7 , the first accessory F1 can be connected to the first slot S1. That is, if Figure 7 As shown, the first fitting F1, the first groove S1, the through-line 11, and the suction holes H can be arranged to be in gaseous communication with each other. Thus, when the vacuum device connected to the first fitting F1 is operated, a vacuum is generated in the suction holes H at the position connected to the first fitting F1, so that the tape T facing the corresponding position can be effectively sucked.

[0077] Reference Figure 8 , the second accessory F2 can be connected to the second slot S2. That is, if Figure 8 As can be seen in the figure, the second fitting F2, second slot S2, through-line 11, and suction holes H can be configured to be in gaseous communication with one another. Thus, when the air blowing device connected to the second fitting F2 is in operation, gas is discharged through the suction holes H at the position connected to the second fitting F2, effectively releasing the tape T from the corresponding position. If only a simple vacuum release is performed instead of air blowing, the performance of the tape T's connection may be degraded. Therefore, in the present disclosure, in addition to simple vacuum release, an air blow to exhaust gas can also be applied to ensure reliable release of the tape T at the predetermined position.

[0078] In yet another aspect of the present disclosure, at least one of the first accessory F1 and the second accessory F2 may be provided in plural numbers.

[0079] For example, refer to Figure 5 and Figure 6 , each first slot S1 can connect two first accessories F1. However, the scope of the present disclosure is not limited to two accessories per slot, and it is obvious that an embodiment in which three or more accessories are connected to each slot is also included in the scope of the present disclosure.

[0080] According to this structure, due to the structure of multiple accessories connected to a single slot, a uniform vacuum and / or blowing effect can be achieved. For example, when only one accessory is configured to be connected to a slot having an arc shape extending in the circumferential direction (e.g., the first slot S1), the vacuum and / or blowing effect can be stronger in the suction holes H located near the point where the accessory is connected, while the vacuum and / or blowing effect can be relatively weaker in the suction holes H located in the remaining area. However, according to the embodiments of the present disclosure as described above, a uniform airflow can occur in all suction holes H within a slot.

[0081] According to another aspect of the present disclosure, a first valve for controlling the inflow and outflow of gas may be provided between the first fitting F1 and the vacuum device, and a second valve for controlling the inflow and outflow of gas may be provided between the second fitting F2 and the blowing device.

[0082] Although not shown in the drawings, the first fitting F1 may be connected to the vacuum device via a predetermined hose or pipe. In this case, the first valve may be provided on the hose or pipe. Figure 5 , the present disclosure may include three first slots S1, that is, three vacuum slots. Here, further reference is made to Figure 6 Each first tank S1 can be connected to two first fittings F1. Therefore, in this embodiment, a total of six first fittings F1 can be provided. Each first fitting F1 can be connected to a vacuum device via a pipeline, and a first valve can be provided on an integrated pipeline of each pipeline combination.

[0083] That is, according to the present disclosure, only one first valve can be configured to be provided on the integrated pipeline of each pipeline combination. Therefore, according to the present disclosure, the vacuum of the entire device can be controlled by a single valve control. Therefore, the management points of electrical equipment can be significantly reduced.

[0084] Alternatively, the first valve can be provided on each pipeline instead of on the integrated pipeline. If the vacuum timing is configured differently for each position of the first tank S1, the first valve can be provided on each pipeline. Alternatively, a valve can also be provided for each tank.

[0085] Likewise, the second fitting F2 can be connected to the blowing device via a predetermined hose or pipe. In this case, the second valve can be provided on the hose or pipe. Figure 5 , the present disclosure may include two second slots S2, that is, two blowing slots. Here, further reference is made to Figure 6Each second slot S2 can be connected to a second fitting F2. Therefore, in this embodiment, a total of two second fittings F2 can be provided. Each second fitting F2 can be connected to the blowing device via a pipe, and the second valve can be provided on the integrated pipeline of each pipe combination.

[0086] That is, according to the present disclosure, only one second valve can be configured to be provided on the integrated pipeline of each pipeline combination. Therefore, according to the present disclosure, the air blowing of the entire device can be controlled by controlling a single valve. Therefore, the management points of electrical equipment can be significantly reduced.

[0087] Alternatively, the second valve may be provided on each pipe, rather than on the integrated pipeline. If the blowing timing is configured differently for each position of the second slot S2, a second valve may be provided on each pipe. Alternatively, a valve may be provided for each slot.

[0088] In conventional rotary equipment, a vacuum chamber is formed for each head position of the object being transported, and a separate valve is installed for each vacuum chamber. This requires multiple valves, and the opening and closing timing of each valve must be adjusted individually. However, the above-mentioned structure of the present disclosure can significantly reduce the number of valves required. This effectively reduces equipment costs and significantly reduces the number of electrical equipment management points.

[0089] In addition, in another aspect of the present disclosure, the first valve and the second valve may be solenoid valves. By configuring the valves as solenoid valves in this manner, the inflow and outflow of gas can be effectively controlled by electrical signals.

[0090] However, the types of the first and second valves of the present disclosure are not limited to solenoid valves, and it is apparent that any valve capable of controlling the inflow and outflow of gas may be applied to the first and / or second valves of the present disclosure.

[0091] Figure 9 is used to describe Figure 1 Diagram of the vacuum section of the conveyor 1 and the point where the vacuum ends, Figure 10 is used to describe the Figure 1 FIG. 1 is a diagram showing a process in which the conveying device 1 delivers the tape T to the tape T attachment tray.

[0092] Figure 9A plan view of the gasket 30 is shown, which, as described above, does not rotate and remains stationary. In this case, the first disk 10 located below the gasket 30 can rotate. For example, the first disk 10 can rotate counterclockwise. That is, the first disk 10 can rotate counterclockwise below the gasket 30. The first disk 10 can be configured to transfer the tape T from a first point P1 to a second point P2. That is, the first disk 10 can take over the tape T from another rotary device at the first point P1. The first point P1 is where the first slot S1 begins, and vacuum can be generated from the first point P1 and maintained until the point where the first slot S1 ends. Therefore, the vacuum can be maintained until the second point P2. Furthermore, the second point P2 is where the second slot S2 begins, and air blow is generated at the second point P2. In other words, the tape T attached to the first disk 10 at the first point P1 can be transferred counterclockwise and then handed over to the next rotary device at the second point P2.

[0093] Reference Figure 10 , the conveyor 1 can take over the tape T from a predetermined position, convey the tape T in a counterclockwise direction, and hand it over to the right-hand rotator at a second point P2. In other words, the conveyor 1 can also hand the tape T over to the next rotating device at the point of contact with the next rotating device. Here, the next rotating device can be, for example, the rotating device that wraps the tape T around the outer surface of the battery cell. In this case, the attachment of the tape T to the outer surface of the battery cell can be completed at a third point P3, for example.

[0094] According to the various embodiments described above, the present disclosure can improve the consistency of vacuum application and vacuum release timing during the transfer of battery cells or components constituting the battery cells. Furthermore, the number of components constituting the transfer device 1 can be reduced, and accordingly, the number of device management points can be reduced, and costs can be reduced, thereby ensuring economic feasibility.

[0095] Furthermore, the terms indicating directions (such as upper and lower) as used herein are only used for convenience of description, and it is obvious to one of ordinary skill in the art that the terms may vary depending on the position of the element or the observer.

[0096] The present disclosure has been described above with respect to a limited number of embodiments and drawings, but the present disclosure is not limited thereto, and various modifications and variations will be possible for those skilled in the art to which the present disclosure pertains within the technical aspects of the present disclosure and the scope of the appended claims and their equivalents.
