Description

[0005] ,

[0004] ,

[0001] The present invention relates to an apparatus for transferring an object, particularly a battery cell or a component constituting a battery cell.

[0002] This application claims priority based on Korean Patent Application No. 10-2023-0119927 filed on September 8, 2023, and all the contents disclosed in the specification and drawings of the said application are incorporated into this application.

Background Art

[0003] Secondary batteries, which are highly applicable to a group of products and have electrical characteristics such as high energy density, are generally applied not only to portable devices but also to electric vehicles (EVs) or hybrid electric vehicles (HEVs) driven by an electric drive source. Such secondary batteries are attracting attention as a new energy source for environmental consideration and improving energy efficiency because they not only have the main advantage of being able to dramatically reduce the use of fossil fuels but also have the advantage of generating no by-products from energy use.

[0004] Currently, widely used types of secondary batteries include lithium-ion batteries, lithium polymer batteries, nickel cadmium batteries, nickel metal hydride batteries, nickel zinc batteries, etc. The operating voltage of such a unit secondary battery cell, that is, a unit battery cell, is about 2.5V to 4.5V. Therefore, when a higher output voltage is required, a plurality of battery cells may be connected in series to form a battery pack. Also, depending on the charge and discharge capacity required for the battery pack, a plurality of battery cells may be connected in parallel to form a battery pack. Therefore, the number of battery cells included in the said battery pack can be variously set according to the required output voltage and / or charge and discharge capacity.

[0005] On the other hand, rotary equipment is used in various processes in the manufacturing of such secondary batteries. For example, this could include transfer devices used to move battery cells or components that make up battery cells from one process to the next. Such rotary equipment structures perform their operations by sending and receiving signals via solenoid valves in response to vacuum and release in the disk section where components are transferred and retrieved.

[0006] However, due to the characteristics of high-speed rotary equipment, there was a problem in coordinating the timing of vacuum suction and release during the pickup and delivery of parts. Specifically, problems such as malfunctions due to delays in vacuuming and vacuum release occurred. In addition, the number of electrical wiring components required increased depending on the number of parts being transported, leading to an increase in the number of electrical components that needed to be managed and thus increasing equipment costs. [Overview of the project] [Problems that the invention aims to solve]

[0007] Therefore, in order to solve the above problems, one objective of the present invention is to improve the timing consistency of vacuuming and devacuuming during the transfer of battery cells or components constituting battery cells.

[0008] In another embodiment, the present invention aims to reduce costs by reducing the number of components constituting the transfer device, thereby reducing the number of parts that need to be managed in the device.

[0009] However, the technical problems that this invention aims to solve are not limited to those mentioned above, and other problems not mentioned will be clearly understood by an ordinary person of the art from the description of the invention below. [Means for solving the problem]

[0011] Preferably, the second disk and the gasket may be configured not to rotate.

[0012] In one embodiment of the present invention, the first disk may have a plurality of adsorption holes along the circumferential direction.

[0013] Preferably, the adsorption holes may be configured to adsorb and detach objects to be transported.

[0014] In another embodiment of the present invention, the gasket may include at least one first slot and one second slot, each configured to penetrate in a direction parallel to the central axis and to have a predetermined space.

Advantages of the Invention

[0025] According to the present invention, it is possible to improve the consistency of the timing of vacuum and vacuum release during the transfer of a battery cell or components constituting a battery cell.

[0026] In another aspect, according to the present invention, the number of components constituting the transfer device can be reduced.

[0027] Thereby, the number of parts to be managed in the device can be reduced, and cost can be reduced, ensuring economic efficiency.

[0029] The following drawings accompanying this specification illustrate preferred embodiments of the invention and, together with the detailed description of the invention, serve to further illustrate the technical idea of ​​the invention; therefore, the invention should not be construed as being limited solely to what is shown in the drawings. [Brief explanation of the drawing]

[Figure 10] Figure 1 is a diagram illustrating the process by which the transfer device delivers the tape to the tape mounting disk. [Modes for carrying out the invention]

[0031] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. Prior to this, terms and words used in this specification and in the claims shall not be interpreted in their usual and dictionary sense, but rather in a sense and concept appropriate to the technical idea of ​​the present invention, in accordance with the principle that the inventor himself may appropriately define the concept of terms in order to best describe the invention.

[0032] Therefore, it should be understood that the configurations shown in the embodiments described herein represent only one of the most preferred embodiments of the present invention and do not represent the entire technical concept of the present invention, and that there are various equivalents and modifications that can be substituted therein at the time of filing this application.

[0033] Furthermore, in order to facilitate understanding of the invention, the accompanying drawings are not shown to actual scale, and the dimensions of some components may be exaggerated.

[0034] Conventionally, rotary equipment has been used in various processes in the manufacturing of secondary batteries. For example, this could include transfer devices used to move battery cells or components that make up battery cells from one process to the next. Such rotary equipment structures perform their operations by sending and receiving signals via solenoid valves in response to vacuum and release in the disk section where components are transferred and retrieved.

[0035] However, due to the characteristics of high-speed rotary equipment, there was a problem in coordinating the timing of vacuum suction and release during the pickup and delivery of parts. Specifically, problems such as malfunctions due to delays in vacuuming and vacuum release occurred. In addition, the number of electrical wiring components required increased depending on the number of parts being transported, leading to an increase in the number of electrical components that needed to be managed and thus increasing equipment costs.

[0036] More specifically, in conventional rotary equipment, the transfer device formed a vacuum chamber for each disk head, and a solenoid valve was installed in each vacuum chamber to achieve vacuum and devacuum. For example, if there were six disk heads, it was necessary to form six vacuum chambers and include six solenoid valves. This method of controlling the vacuum by providing a valve for each head not only presented cost problems, but also resulted in an excessively large number of components constituting the transfer device, such as solenoid valves and electrical wiring, and an increase in the number of points that needed to be managed.

[0037] The present invention aims to solve the above problems, and below, with reference to Figures 1 to 10, the transfer device 1 for achieving the above objective will be described in detail.

[0038] Figure 1 is a diagram illustrating a transfer device 1 according to one embodiment of the present invention, and Figure 2 is an exploded perspective view of Figure 1.

[0039] Referring to Figures 1 and 2, the transfer device 1 according to one embodiment of the present invention includes a first disk 10, a second disk 20, and a gasket 30.

[0040] More specifically, the transfer device 1 may include a first disk 10 having the shape of a disc and configured to be rotatable with respect to the central axis C of the disc, a second disk 20 having the shape of a disc and provided above the first disk 10, and a gasket 30 interposed between the first disk 10 and the second disk 20.

[0041] The gasket 30 can ensure airtightness between the first disk 10 and the second disk 20. The gasket 30 may be configured to generate a vacuum, release the vacuum, or blow air at a predetermined location. The object being transported may be configured to be attracted to and detached from the first disk 10.

[0042] This structure allows for a reduction in the number of valves that were previously applied at each location where vacuuming and devacuuming were required. This reduces equipment costs. Furthermore, it improves the consistency of the timing of pickup and delivery, which was previously synchronized by the electrical signals of the valves. In other words, according to the present invention, by improving the consistency of the timing of pickup and delivery through mechanical structural improvements and reducing the number of valves required for the suction and detachment of objects to be transported, unnecessary wiring work and complexity can be reduced.

[0043] Preferably, the second disk 20 and the gasket 30 may be configured not to rotate. That is, only the first disk 10 may rotate, while the second disk 20 and the gasket 30 may be configured not to rotate.

[0044] With this structure, the object to be transported can be moved by rotating only the first disk 10 that transports the object, and the second disk 20 and gasket 30, which do not come into direct contact with the object being transported, are kept fixed, thereby increasing the efficiency of the device and minimizing unnecessary operation and movement.

[0045] Figure 3 is a diagram illustrating the first disk 10 included in the transfer device 1 of Figure 1, and Figure 4 is a side view of the first disk 10 of Figure 3.

[0046] In one embodiment of the present invention, the first disk 10 may have a plurality of adsorption holes H along the circumferential direction.

[0047] For example, referring to Figures 3 and 4, the first disk 10 may have a substantially circular disc shape. In this case, the first disk 10 may be provided with a plurality of through lines 11 that penetrate in a direction parallel to the central axis C. That is, the through lines 11 may be configured to have a tubular space that penetrates the upper and lower surfaces of the first disk 10. The through lines 11 may be arranged in a plurality along the circumferential direction with respect to the central axis C.

[0048] On the other hand, referring to Figures 3 and 4, the first disk 10 may have a plurality of suction holes H along the circumferential direction. The suction holes H may be provided on the side surface of the first disk 10. A plurality of the suction holes H may be provided on the side surface of the first disk 10. The suction holes H may be configured to be connected to the through line 11. That is, the suction holes H may be configured as tubular passages from the outer surface of the first disk 10 to the through line 11. Therefore, the suction holes H and the through line 11 can communicate with each other.

[0049] In another embodiment of the present invention, there may be multiple adsorption pores H physically connected to a single through-line 11. For example, referring to Figure 3, there may be three adsorption pores H connected to a single through-line 11. This will be described in more detail later with reference to Figures 7 and 8.

[0050] In yet another embodiment of the present invention, the adsorption holes H may be configured to adsorb and desorb objects to be transported. That is, according to the present invention, by controlling the inflow and outflow of gas through the through-line 11 and the adsorption holes H, the adsorption and desorption of objects to be transported that come into contact with the adsorption holes H can be controlled.

[0051] For example, referring to Figure 4, the object to be transferred may be a tape T. The tape T may be a tape T that surrounds the outer surface of a 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 a cylindrical battery cell is composed of a conductor and generally has a negative or positive electrode, 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. Thus, before performing the step of surrounding the outer surface of the battery cell with the tape T, it may be necessary to transfer the tape T to the above step. The present invention may be a transfer device 1 for transferring such a tape T. Referring to Figure 4, a plurality of suction holes H are provided on the side surface of the first disk 10, and the tape T can be attached and / or detached at positions opposite to the plurality of suction holes H. That is, the tape T can be attached to the side surface of the first disk 10 at a predetermined point, and the tape T can be detached from the side surface of the first disk 10 at a predetermined point. According to the present invention, such mounting points and detachment points can be fixed in specific positions, and the control accuracy of the mounting and detachment points can be improved in the process.

[0052] Figure 5 is a diagram illustrating the gasket 30 included in the transfer device 1 shown in Figure 1.

[0053] In another embodiment of the present invention, the gasket 30 may include a first slot S1 and a second slot S2. More specifically, it may include at least one first slot S1 and one second slot S2, each configured to penetrate in a direction parallel to the central axis C and to have a predetermined space.

[0054] For example, referring to Figure 5, the gasket 30 may include a plurality of first slots S1 and a plurality of second slots S2 that penetrate in a direction parallel to the central axis C. Here, the first slots S1 may be vacuum slots, and the second slots S2 may be air blow slots. For example, a vacuum may be generated at the position corresponding to the first slot S1, and gas discharge may occur at the position corresponding to the second slot S2. Here, the first slots S1 and the second slots S2 may be configured to communicate with the through lines 11 of the first disk 10. That is, the gasket 30 may be located above the first disk 10, and the first slots S1 or the second slots S2 may be located above the plurality of through lines 11 provided in the first disk 10. In this way, the first slots S1, the through lines 11, and the adsorption holes H may be configured to allow gas to communicate with each other. Similarly, the second slots S2, the through lines, and the adsorption holes H may also be configured to allow gas to communicate with each other.

[0055] With this structure, a vacuum is generated in the suction hole H at the position corresponding to the first slot S1, and the tape T in contact with the suction hole H at the position corresponding to the first slot S1 can be effectively adsorbed. Furthermore, an air blow is generated in the suction hole H at the position corresponding to the second slot S2, and the tape T that was in contact with the suction hole H at the position corresponding to the second slot S2 can be effectively attached and detached. In other words, according to the present invention, it is possible to control the vacuum and devacuation in a specific area and / or location.

[0056] In yet another embodiment of the present invention, the first slot S1 and the second slot S2 may have an arc shape formed such that they have a predetermined angle as a central angle around the central axis C.

[0057] For example, referring to Figure 5, the first slot S1 may have an arc shape with a predetermined angle as the central angle around the central axis C. In this case, if the predetermined angle becomes extremely small, the arc shape may become circular. For example, referring to Figure 5, the second slot S2 may have such a circular shape.

[0058] With this structure, the shapes of the first slot S1 and the second slot S2 can be configured in various ways. This allows the timing of vacuum and air blowing to be configured in various ways depending on the situation. For example, if the length of the tape T to be attached changes, the position and angle of the first slot S1 and the second slot S2 can be changed to match the changed length, thereby enabling the attachment and detachment of the modified tape T.

[0059] In yet another embodiment of the present invention, the gasket 30 may have, for example, a ring shape. However, the shape of the gasket 30 is not limited thereto, and any shape that can be interposed between the first disk 10 and the second disk 20 is included within the scope of the present invention. For example, the gasket 30 may have a disc shape.

[0060] Figure 6 is a diagram illustrating the second disk 20 included in the transfer device 1 of Figure 1.

[0061] In yet another embodiment of the present invention, the second disk 20 may include a first fitting F1 and a second fitting F2. More specifically, the second disk 20 may include a first fitting F1 connected to a vacuum device and a second fitting F2 connected to an air blow device.

[0062] With this structure, the first fitting F1 and the second fitting F2 can serve as passages for the inflow and outflow of gas. That is, the first fitting F1 is connected to a vacuum device, which may further include piping for the connection. Therefore, when the vacuum device is in operation, gas can move out of the first fitting F1 through the first fitting F1. Similarly, the second fitting F2 is connected to an air blow device, which may further include piping for the connection. Therefore, when the air blow device is in operation, gas can move from the outside to the inside of the second fitting F2 through the second fitting F2.

[0063] Figure 7 is a longitudinal cross-sectional view of the transfer device 1 in Figure 1, cut at a predetermined angle, and Figure 8 is a longitudinal cross-sectional view of the transfer device 1 in Figure 1, cut at a different angle than in Figure 7.

[0064] Referring to Figure 7, the first fitting F1 may be connected to the first slot S1. That is, as can be seen from Figure 7, the first fitting F1, the first slot S1, the through line 11, and the adsorption hole H may be configured to allow gas to communicate with each other. As a result, when a vacuum device connected to the first fitting F1 is activated, a vacuum is generated at the adsorption hole H at the position communicating with the first fitting F1, and the tape T facing that position can be effectively adsorbed.

[0065] Referring to Figure 8, the second fitting F2 can be connected to the second slot S2. That is, as can be seen from Figure 8, the second fitting F2, the second slot S2, the through line 11, and the adsorption hole H can be configured to allow gas to communicate with each other. As a result, when the air blow device connected to the second fitting F2 is activated, gas is discharged from the adsorption hole H at the position communicating with the second fitting F2, allowing the tape T facing that position to be effectively attached and detached. If only simple vacuum release is performed instead of air blowing, the tape T transfer performance may be reduced. Therefore, in the present invention, by applying air blowing that discharges more gas than simple vacuum release, reliable release of the tape T from a predetermined position can be ensured.

[0066] In yet another embodiment of the present invention, at least one of the first fitting F1 and the second fitting F2 may be provided in multiple quantities.

[0067] For example, referring to Figures 5 and 6, two first fittings F1 may be connected to one first slot S1. However, the scope of the present invention is not limited to two fittings per slot, and embodiments configured to connect three or more fittings per slot are also included within the scope of the present invention.

[0068] With such a structure, a uniform vacuum and / or air blow effect can be achieved by connecting multiple fittings to a single slot. For example, if only one fitting is connected to a slot with a long, arc-shaped form in the circumferential direction, such as the first slot S1, the vacuum and / or air blow may be strong in the adsorption holes H located near the point where the fitting is connected, while the vacuum and / or air blow may be relatively weak in the adsorption holes H located in the remaining area. However, according to the above-described embodiment of the present invention, a uniform airflow can be generated in all adsorption holes H within a single slot.

[0069] According to yet another aspect of the present invention, a first valve configured to control the inflow and outflow of gas may be provided between the first fitting F1 and the vacuum device. A second valve configured to control the inflow and outflow of gas may be provided between the second fitting F2 and the air blow device.

[0070] Although not shown in the figures, the first fitting F1 may be connected to a vacuum device via a predetermined hose or piping. In this case, a first valve may be provided on the hose or piping. Referring to Figure 5, for example, the present invention may include three first slots S1, i.e., three vacuum slots. Referring further to Figure 6, two first fittings F1 may be connected to each first slot S1. Thus, in this embodiment, a total of six first fittings F1 may be provided. Each first fitting F1 is connected to a vacuum device via piping, and a first valve may be provided on an integrated piping line formed by combining the pipes.

[0071] In other words, according to the present invention, the system can be configured to have only one first valve on an integrated piping line that combines each pipe. Therefore, according to the present invention, the vacuum of the entire system can be controlled through a single valve control. This significantly reduces the number of electrical components that need to be managed.

[0072] Alternatively, the first valve can be installed on each individual pipe rather than on the integrated piping line. If it is desired that the timing of vacuuming differs for each location in the first slot S1, the first valve can be installed on each individual pipe. Alternatively, a valve can be installed for each slot.

[0073] Similarly, the second fitting F2 may be connected to an air blow device via a predetermined hose or piping. In this case, a second valve may be provided on the hose or piping. Referring, for example, to Figure 5, the present invention may include two second slots S2, i.e., two air blow slots. Referring further to Figure 6, one second fitting F2 may be connected to each second slot S2. Thus, in this embodiment, a total of two second fittings F2 may be provided. Each second fitting F2 is connected to an air blow device via piping, and a second valve may be provided on the integrated piping line combining the respective pipes.

[0074] In other words, according to the present invention, the system can be configured to have only one second valve on an integrated piping line that combines each pipe. Therefore, according to the present invention, the air blow of the entire system can be controlled through a single valve control. This significantly reduces the number of electrical components that need to be managed.

[0075] Alternatively, the second valve can be installed on each individual pipe rather than on the integrated piping line. If it is desired to configure the timing of air blowing to differ for each of the two second slots S2, a second valve can be installed on each pipe. Alternatively, a valve can be installed for each slot.

[0076] Conventional rotary equipment requires a large number of valves because a vacuum chamber is formed at each head point of the object being transported, and each vacuum chamber has its own individual valve, requiring individual adjustment of the opening and closing timing for each valve. However, with the structure described above in the present invention, the number of valves required can be significantly reduced. This effectively reduces equipment costs and significantly reduces the number of electrical components that need to be managed.

[0077] On the other hand, in yet another embodiment of the present invention, the first valve and the second valve may be solenoid valves. By configuring the valves as solenoid valves in this way, the inflow and outflow of gas can be effectively controlled by electrical signals.

[0078] However, it goes without saying that the types of the first and second valves of the present invention are not limited to solenoid valves, and any valve capable of controlling the inflow and outflow of gas can be applied as the first and / or second valves of the present invention.

[0079] Figure 9 is a diagram illustrating the vacuum section of the transfer device 1 in Figure 1 and the point where the vacuum ends, and Figure 10 is a diagram illustrating the process by which the transfer device 1 in Figure 1 transfers the tape T to the tape T mounting disk.

[0080] Figure 9 shows a plan view of the gasket 30, which remains fixed without rotating as described above. At this time, 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 may be configured to transfer the tape T from a first point P1 to a second point P2. That is, the first disk 10 can pick up the tape T from another rotary at the first point P1. The first point P1 is the starting position of the first slot S1, and a vacuum can be generated from the first point P1 to the end of the first slot S1. Therefore, the vacuum can be maintained up to the second point P2. On the other hand, the second point P2 is the starting position of the second slot S2, and an air blow occurs at the second point P2. In other words, the tape T attached to the first disk 10 at the first location P1 is transported counterclockwise and then handed over to the next rotary equipment at the second location P2.

[0081] Referring to Figure 10, the transfer device 1 can take the tape T from a predetermined position, transfer it counterclockwise, and hand over the tape T to the right-hand rotary at the second point P2. That is, the transfer device 1 can hand over the tape T to the next rotary equipment at the point where it comes into contact with the next rotary equipment. Here, the next rotary equipment may be, for example, a rotary equipment that performs the process of surrounding the outer surface of a battery cell with the tape T. In this case, for example, the attachment of the tape T to the outer surface of the battery cell can be completed at the third point P3.

[0082] Through the various embodiments described above, the present invention can improve the timing consistency of vacuuming and devacuuming during the transfer of battery cells or components constituting battery cells. Furthermore, the number of components constituting the transfer device 1 can be reduced, thereby reducing the number of parts that need to be managed in the device and reducing costs, thus ensuring economic efficiency.

[0083] On the other hand, while terms indicating directions such as up and down are used in this specification, it will be obvious to an ordinary person skilled in the present invention that such terms are for convenience of explanation and can change depending on the position of the object in question, the position of the observer, etc.

[0084] Although the present invention has been described above with reference to limited embodiments and drawings, it goes without saying that the present invention is not limited thereto, and various modifications and variations are possible within the equivalent scope of the technical idea of ​​the present invention and the claims described below by persons with ordinary skill in the art to which the present invention pertains.
