Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and more specifically, to an electrode processing system and method. Background Technology

[0002] For processing steps such as cleaning and thinning of electrode strips, in actual processing, the electrode strip usually needs to be stopped from transporting before the platform can be flattened and laser processing can begin. After laser processing is completed, the vacuum needs to be broken to release the electrode strip before starting the next cycle.

[0003] This processing method results in a slow overall production cycle. The total processing time is the sum of the electrode material conveying time, electrode material adsorption time, laser processing time, and electrode material release time, which severely slows down the overall processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an electrode processing system and method that enables on-flight processing of electrode strips without stopping. During the adsorption, release, and overall processing of the electrode strips, the electrode strips are continuously transported, which greatly shortens the processing time and thus improves the processing efficiency.

[0008] A processing mechanism, located on the other side of the processing section, is configured to process the electrode strip on the adsorption platform at a flight processing speed V3 when the electrode strip is conveyed at the first conveying speed V1a, wherein the flight processing speed V3 is the same as the first conveying speed V1a, so that the processing mechanism processes the electrode strip synchronously.

[0009] In an optional embodiment, the conveying mechanism is further configured to convey the electrode strip at a second conveying speed V1b when the processing area leaves the processing section, wherein the second conveying speed V1b is greater than the first conveying speed V1a.

[0010] In an optional embodiment, the processing mechanism includes a laser cleaning assembly configured to project a laser beam onto the electrode strip, and the laser beam moves along the conveying direction of the electrode strip at the flight processing speed V3 in the working area of ​​the electrode strip, so that the laser cleaning assembly performs laser cleaning on the processing area of ​​the electrode strip.

[0011] In an optional embodiment, the electrode processing system further includes a linear module disposed on one side of the processing section and extending along the conveying direction of the electrode strip. The adsorption platform is movably disposed on the linear module. The linear module is configured to drive the adsorption platform to move at a first motion speed V2a along the conveying direction of the electrode strip when the electrode strip is conveyed at the first conveying speed V1a. The linear module is also configured to move at a second motion speed V2b in the opposite direction to the conveying direction of the electrode strip when the electrode strip is conveyed at the second conveying speed V1b.

[0012] In an optional embodiment, a lifting base is movably disposed on the linear module, and the adsorption platform is disposed on the lifting base. The lifting base is configured to drive the adsorption platform to rise or fall relative to the linear module, so that the adsorption platform approaches or detaches from the electrode strip.

[0013] In an optional embodiment, the conveying mechanism includes an infeed roller group and an outlet roller group, which are spaced apart and form the processing section between them, and the adsorption platform is disposed between the infeed roller group and the outlet roller group.

[0014] In an optional embodiment, the electrode processing system further includes a detector disposed on the conveying mechanism and configured to detect a first conveying speed V1a of the electrode strip.

[0015] Secondly, the present invention provides an electrode processing method applicable to the electrode processing system described in the foregoing embodiments, the method comprising:

[0016] When entering the processing section from the processing area, the electrode strip is conveyed by a conveying mechanism at a first conveying speed V1a, wherein the processing areas are distributed at intervals on the front side of the electrode strip along the conveying direction of the electrode strip;

[0017] The adsorption platform moves along the conveying direction of the electrode strip at a first speed V2a, wherein the first speed V2a is the same as the first conveying speed V1a, so that the adsorption platform and the electrode strip move synchronously.

[0018] The adsorption platform is adsorbed onto the back side of the electrode strip corresponding to the processing area;

[0019] The electrode strip on the adsorption platform is processed by a processing mechanism at a flight processing speed V3, wherein the flight processing speed V3 is the same as the first conveying speed V1a, so that the processing mechanism processes the electrode strip synchronously.

[0020] Separate the adsorption platform from the electrode material strip.

[0021] In an optional embodiment, after the step of separating the adsorption platform from the electrode strip, the method further includes:

[0023] In an optional embodiment, after the step of separating the adsorption platform from the electrode strip, the method further includes:

[0024] The adsorption platform is moved to the initial position at a second speed V2b, wherein the direction of the second speed V2b is opposite to the direction of the first speed V2a.

The electrode strip is conveyed at a first conveying speed V1a when it enters a processing section within a processing area using a conveying mechanism. While the electrode strip is being conveyed at the first conveying speed V1a, an adsorption platform is positioned opposite the back side of the processing area and moves along the conveying direction of the electrode strip at a first movement speed V2a, where the first movement speed V2a is the same as the first conveying speed V1a, to synchronize the movement of the adsorption platform and the electrode strip. Simultaneously, while the electrode strip is being conveyed at the first conveying speed V1a, the processing mechanism processes the electrode strip on the adsorption platform at a flight processing speed V3, where the flight processing speed V3 is the same as the first conveying speed V1a, to synchronize the processing of the electrode strip.

[0029] Compared with the prior art, the electrode processing system and method provided in this embodiment of the invention, through synchronous control, can utilize the adsorption platform to move synchronously with the electrode strip and utilize the processing mechanism to process the electrode strip synchronously. This enables the electrode strip to be processed while in transport, and enables the electrode strip to be processed in flight without stopping, which greatly shortens the processing time and thus improves the processing efficiency.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0045] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0046] As disclosed in the background section, existing processing methods require the electrode strip to be stopped from transporting before the platform can be flattened and laser processing can begin. This is especially true for processes like electrode cleaning and thinning, which heavily rely on the support of the adsorption platform. Therefore, processing can only proceed when the processing mechanism, adsorption mechanism, and electrode strip are all stationary. In this scenario, traditional processing solutions require the electrode strip to be stopped before the adsorption platform and processing mechanism can process the stationary strip. Consequently, conventional techniques require slowing down and stopping the electrode strip, followed by adsorption, laser processing, and release, before finally accelerating it again. This results in processing time encompassing transport time, adsorption time, laser processing time, and release time, undoubtedly leading to excessively long processing times and reduced efficiency.

[0047] To address the aforementioned problems, embodiments of the present invention provide an electrode processing system and method. It should be noted that, unless otherwise specified, the features in the embodiments of the present invention can be combined with each other.

[0048] join Figure 1 , Figure 2 and Figure 4 This invention provides an electrode processing system 100 that enables on-flight processing of electrode strips 200 without stopping. During the adsorption, release, and overall processing of the electrode strips 200, the electrode strips 200 are continuously transported, greatly shortening the processing time and thus improving processing efficiency.

[0049] The electrode processing system 100 provided in this embodiment of the invention includes a conveying mechanism 110, an adsorption platform 120, and a processing mechanism 130. The conveying mechanism 110 is configured to periodically convey electrode strips 200 at a second conveying speed V1b and a first conveying speed V1a within a processing section 111. Specifically, the conveying mechanism 110 is configured to convey the electrode strips 200 at the first conveying speed V1a when the processing area 210 enters the processing section 111, and the processing areas 210 are spaced apart on the front side of the electrode strips 200 along the conveying direction of the electrode strips 200. Simultaneously, the conveying mechanism 110 is also configured to convey the electrode strips 200 at a second conveying speed V1b when the processing area 210 leaves the processing section 111, wherein the second conveying speed V1b is greater than the first conveying speed V1a. The front side of the electrode strips 200 has processing areas 210 spaced apart along the conveying direction. An adsorption platform 120 is disposed on one side of the processing section 111. The adsorption platform 120 is configured to adsorb the electrode strip 200 corresponding to the back side of the processing area when the electrode strip 200 is conveyed at a first conveying speed V1a, and to move along the conveying direction of the electrode strip 200 at a first movement speed V2a, wherein the first movement speed V2a is the same as the first conveying speed V1a, so that the adsorption platform 120 and the electrode strip 200 move synchronously. A processing mechanism 130 is disposed on the other side of the processing section 111 and is configured to process the electrode strip 200 on the adsorption platform 120 at a flight processing speed V3 when the electrode strip 200 is conveyed at the first conveying speed V1a, wherein the flight processing speed V3 is the same as the first conveying speed V1a, so that the processing mechanism 130 processes the electrode strip 200 synchronously.

[0050] It should be noted that, in this embodiment, the processing section 111 refers to the area on the conveying mechanism 110 that can process the electrode strip 200. The processing mechanism 130 is located above the processing section 111, that is, above the electrode strip 200, so that it can process the front processing area 210. The adsorption platform 120 is located below the processing section 111, that is, below the electrode strip 200, so that it can adsorb the back side of the electrode strip 200.

[0051] It is worth noting that in this embodiment, the second conveying speed V1b is greater than the first conveying speed V1a. That is, the conveying mechanism 110 can drive the electrode strip 200 to periodically be conveyed at high speed (V1b) and low speed (V1a). When the electrode strip 200 is conveyed at low speed, the processing action can be completed. This deceleration processing method can, on the one hand, ensure that the electrode strip 200 does not stop, greatly shortening the processing time and improving the processing efficiency; on the other hand, it can reduce the processing difficulty, allowing the adsorption platform 120 and the processing mechanism 130 to keep up with the speed of the electrode strip 200, thus making it easier to achieve a "relatively static" state. Of course, in other preferred embodiments of the present invention, the second conveying speed V1b can also be the same as the first conveying speed V1a, thereby achieving uniform speed conveying of the electrode strip 200.

[0052] In actual operation, the electrode strip 200 is periodically conveyed by the conveying mechanism 110 at a second conveying speed V1b and a first conveying speed V1a, wherein the second conveying speed V1b is greater than the first conveying speed V1a. The front side of the electrode strip 200 has processing areas 210 spaced apart along the conveying direction. When the electrode strip 200 is conveyed at the first conveying speed V1a, the adsorption platform 120 is positioned opposite the back side of the processing area and moves along the conveying direction of the electrode strip 200 at a first movement speed V2a, wherein the first movement speed V2a is the same as the first conveying speed V1a, so that the adsorption platform 120 and the electrode strip 200 move synchronously. Simultaneously, when the electrode strip 200 is conveyed at the first conveying speed V1a, the processing mechanism 130 processes the electrode strip 200 on the adsorption platform 120 at a flight processing speed V3, wherein the flight processing speed V3 is the same as the first conveying speed V1a, so that the processing mechanism 130 processes the electrode strip 200 synchronously. Through synchronous control, the adsorption platform 120 and the electrode strip 200 can move synchronously, and the electrode strip 200 can be processed synchronously by the processing mechanism. This enables the electrode strip 200 to be processed while maintaining transportation, and enables the electrode strip 200 to be processed in flight without stopping, which greatly shortens the processing time and improves the processing efficiency.

[0053] Furthermore, the processing mechanism 130 in this embodiment can process the processing area 210 of the electrode strip 200 at a flight processing speed V3. Specific processing techniques may include electrode cleaning, electrode thinning, or electrode spraying. This embodiment uses electrode cleaning or electrode thinning as an example. Additionally, the "flight processing speed V3" mentioned in this embodiment refers to the speed of the actual processing point (i.e., the point acting on the electrode strip 200) of the processing mechanism 130 along the electrode strip 200 conveying direction. When the processing mechanism 130 is an electrode spraying device, the flight processing speed V3 refers to the speed of the spray nozzle along the electrode strip 200 conveying direction; when the processing mechanism 130 is an electrode cleaning and thinning device, the processing action can be achieved through a laser device, in which case the flight processing speed V3 refers to the speed of the point on the electrode strip 200 acting on it after laser emission along the electrode strip 200 conveying direction.

[0054] In some embodiments, the processing mechanism 130 includes a laser cleaning assembly configured to project a laser beam onto the electrode strip 200. The laser beam moves along the conveying direction of the electrode strip 200 at a flight processing speed V3 within the working area of ​​the electrode strip 200, thereby enabling the laser cleaning assembly to perform laser cleaning on the processing area 210 of the electrode strip 200. Specifically, the laser cleaning assembly is capable of performing laser cleaning operations. Furthermore, the basic structure and working principle of the laser cleaning assembly can be referenced from existing lasers, and its own synchronization algorithm can be used to activate the laser galvanometer, ensuring that the laser beam is always applied to the processing area 210 of the electrode strip 200, thus enabling the laser cleaning assembly to process the electrode strip 200 at a flight processing speed V3.

[0055] It should be noted that in this embodiment, the installation position of the laser cleaning component can be fixed, and the flight processing speed V3 can be achieved simply by the movement of the laser galvanometer, for example, by using a drawing cleaning algorithm to follow the material strip. Of course, in other preferred embodiments of the present invention, the laser cleaning component can also move synchronously, that is, an additional translational mounting stage can be provided, and the translational mounting stage can be used to drive the laser cleaning component and the electrode material strip 200 to move synchronously, which can also achieve the flight processing speed V3.

[0056] In some embodiments, the electrode processing system 100 further includes a linear module 140, which is disposed on one side of the processing section 111 and extends along the conveying direction of the electrode strip 200. An adsorption platform 120 is movably disposed on the linear module 140. The linear module 140 is configured to drive the adsorption platform 120 to move at a first speed V2a along the conveying direction of the electrode strip 200 when the electrode strip 200 is conveyed at a first conveying speed V1a. The linear module 140 is also configured to move at a second speed V2b in the opposite direction to the conveying direction of the electrode strip 200 when the electrode strip 200 is conveyed at a second conveying speed V1b. Specifically, the installation direction of the linear module 140 is parallel to the conveying direction of the electrode strip 200, and the adsorption platform 120 can perform linear reciprocating motion under the drive of the linear module 140. The linear module 140 can be hydraulically driven or electrically driven; its specific structure and working principle can be referenced from existing linear drive modules.

[0057] It is worth noting that in this embodiment of the invention, the linear module 140 drives the adsorption platform 120 to perform linear reciprocating motion between the initial position and the end position. The initial position is the limit position of the adsorption platform 120 moving at the second motion speed V2b, and the end position is the limit position of the adsorption platform 120 moving at the first motion speed V2a. For the specific driving process of the linear module 140, please refer to the following method description.

[0058] In some embodiments, a lifting base 150 is movably disposed on the linear module 140, and an adsorption platform 120 is disposed on the lifting base 150. The lifting base 150 is configured to drive the adsorption platform 120 to rise or fall relative to the linear module 140, so that the adsorption platform 120 approaches or detaches from the electrode strip 200. Specifically, the lifting base 150 is located on the bottom side of the adsorption platform 120, and is preferably a cylinder or an electric push rod, capable of driving the adsorption platform 120 to rise or fall, thereby realizing the adsorption and release action of the electrode strip 200.

[0059] It should be noted that the top surface of the adsorption platform 120 in this embodiment is provided with multiple vacuum adsorption holes. These multiple vacuum adsorption holes can be used to adsorb and fix the electrode strip 200, and also to support the electrode strip 200. For details on the specific structure and adsorption principle of the adsorption platform 120, please refer to the vacuum adsorption technology in the prior art.

[0060] In some embodiments, the conveying mechanism 110 includes an infeed roller group 112 and an outlet roller group 113, which are spaced apart and form a processing section 111 between them. An adsorption platform 120 is disposed between the infeed roller group 112 and the outlet roller group 113. Specifically, at least one of the infeed roller group 112 and the outlet roller group 113 is a drive roller, which can convey the electrode strip 200 and enable periodic high-speed and low-speed conveying. Preferably, the infeed roller group 112 and the outlet roller group 113 can employ an automatic acceleration / deceleration algorithm to achieve different conveying speeds based on the electrode length in the electrode strip 200 and the position of the processing area 210. For example, after positioning the processing area 210, the conveying speed can be reduced to a suitable low speed (first conveying speed V1a), and then accelerated to a high speed (second conveying speed V1b) after processing.

[0061] It should be noted that, in the embodiments of the present invention, "when the processing area 210 enters the processing section 111" refers to the time point at which the processing area 210 on the electrode strip 200 aligns with the feed roller group 112, such as... Figure 4 The phrase "when the processing area 210 separates from the processing section 111" mentioned in this embodiment refers to the time point at which the processing area 210 on the electrode strip 200 aligns with the discharge roller group 113, such as... Figure 9 .

[0062] In some embodiments, the electrode processing system 100 further includes a detector 160 and a controller. The controller is communicatively connected to the detector 160, the linear module 140, the lifting base 150, the conveying mechanism 110, and the laser cleaning assembly. The detector 160 is mounted on the conveying mechanism 110 and configured to detect a first conveying speed V1a of the electrode strip 200, and simultaneously detect the position of the processing area 210 on the electrode strip 200. When the processing area 210 enters the processing section 111, the controller controls the conveying mechanism 110 to decelerate, so that the electrode strip 200 is conveyed at the first conveying speed V1a. The detector 160 can also detect the actual value of the first conveying speed V1a. The controller can control the lifting base 150, linear module 140, and laser cleaning assembly based on the real-time detected first conveying speed V1a. This allows the adsorption platform 120 to adsorb the electrode strip 200 and move it along the conveying direction of the electrode strip 200 at a first movement speed V2a. Simultaneously, the controller controls the laser cleaning assembly to process the electrode strip 200 on the adsorption platform 120 at a flight processing speed V3. Specifically, the detector 160 may include an encoder and a laser sensor, which work together to monitor the position and speed of the electrode strip 200 in real time. Existing detection devices can be referenced for details. The controller can be a conventional MCU, SoC, or PLC capable of mechanism control.

[0063] It should be noted that the first conveying speed V1a needs to be monitored in real time using detector 160. Because the acceleration and deceleration of the conveyor belt typically have slight errors, this results in a slight difference in the first conveying speed V1a across different cycles. This slight difference is crucial for "synchronous operation." By monitoring the first conveying speed V1a in real time, rather than presetting it, it can be ensured that the first movement speed V2a is accurately the same as the first conveying speed V1a, thus guaranteeing synchronization in each processing cycle.

[0064] join Figure 3 This invention also provides an electrode processing method applicable to the electrode processing system 100 as described above. The method includes the following steps:

[0065] S1: When entering the processing section 111 from the processing area 210, the electrode strip 200 is conveyed at a first conveying speed V1a using the conveying mechanism 110.

[0066] Combined with participation Figure 4 , Figure 4 Top view of the 200mm electrode material strip. Figure 1Specifically, the conveying mechanism 110 can periodically drive the electrode strip 200 to move at high and low speeds. The front side of the electrode strip 200 has processing areas 210 spaced apart along the conveying direction. The position of the processing areas 210 can be detected by the detector 160. When the processing area 210 has not entered the processing section 111, the conveying mechanism 110 controls the electrode strip 200 to be conveyed at a second conveying speed V1b. When the processing area 210 of the electrode strip 200 enters the processing section 111, the controller can control the conveying mechanism 110 to decelerate and run the electrode strip 200 at a first conveying speed V1a, thereby achieving deceleration and making it more conducive to achieving "synchronous action".

[0067] S2: The adsorption platform 120 moves along the conveying direction of the electrode strip 200 at a first speed V2a.

[0068] Combined with participation Figure 5 Specifically, the detector 160 can first detect the speed of the electrode strip 200 in real time, and after the electrode strip 200 decelerates, it can detect the real-time first conveying speed V1a and transmit the speed information to the controller. The controller controls the linear module 140 to operate based on the first conveying speed V1a. Specifically, the linear module 140 can be controlled to drive the adsorption platform 120 to accelerate towards the second conveying speed V1b, and quickly accelerate the adsorption platform 120 to the first motion speed V2a, so that the first motion speed V2a is the same as the first conveying speed V1a, so that the adsorption platform 120 and the electrode strip 200 move synchronously.

[0069] S3: Adsorb the adsorption platform 120 onto the back side of the electrode strip 200 corresponding to the processing area 210.

[0070] Combined with participation Figure 6 Specifically, at this time, the linear module 140 has completed acceleration and moves at a constant speed of the first motion speed V2a. Then, the adsorption platform 120 is lifted by the lifting base 150, and the adsorption platform 120 is brought into close contact with the processing area 210 of the electrode strip 200. Then, the vacuum of the adsorption platform 120 is turned on to adsorb the electrode strip 200.

[0071] S4: The electrode strip 200 on the adsorption platform 120 is processed by the processing mechanism 130 at a flight processing speed V3.

[0072] Combined with participation Figure 7The flight processing speed V3 is the same as the first conveying speed V1a, so that the processing mechanism 130 processes the electrode strip 200 synchronously. Specifically, the electrode strip 200 can be processed by a laser processing assembly at a flight processing speed V3. Here, the flight processing speed V3 refers to the laser emitted by the laser processing assembly always acting on the processing area 210 of the electrode strip 200, that is, the laser point of action continuously moves at a flight processing speed V3, and completes the laser cleaning of the processing area 210.

[0073] S5: Separate the adsorption platform 120 from the electrode strip 200.

[0074] Combined with participation Figure 8 Specifically, after processing the processing area 210 is completed, the laser processing component can be stopped, and the linear module 140 can be stopped moving. At the same time, the vacuum of the adsorption platform 120 is closed, so that the adsorption platform 120 releases the electrode strip 200. Then, the adsorption platform 120 is lowered by the lifting base 150, so that the adsorption platform 120 and the electrode strip 200 are completely separated.

[0075] S6: When the electrode strip 200 is separated from the processing section 111 in the processing area 210, the electrode strip 200 is conveyed at the second conveying speed V1b using the conveying mechanism 110.

[0076] Combined with participation Figure 9 The second conveying speed V1b is greater than the first conveying speed V1a. Specifically, after processing is completed, the controller can control the conveying mechanism 110 to accelerate the electrode strip 200 to the second conveying speed V1b, achieving high-speed conveying. Preferably, the first conveying speed V1a can be 3 m / min, and the second conveying speed V1b can be 40 m / min. Of course, this is just an example, and the specific speed can be determined according to the specific structure of the electrode strip 200.

[0077] S7: Move the adsorption platform 120 to the initial position at the second motion speed V2b.

[0078] Please continue to participate. Figure 9 Specifically, the second motion speed V2b is not specifically limited and can be determined based on the actual length of the processing section 111. It is worth noting that steps S5 and S6 can be performed simultaneously, and the adsorption platform 120 needs to be reset before the processing area 210 of the next electrode sheet enters the processing section 111.

[0079] The electrode processing system 100 and method provided in this embodiment of the invention utilize a conveying mechanism 110 to periodically convey electrode strips 200 at a second conveying speed V1b and a first conveying speed V1a, wherein the second conveying speed V1b is greater than the first conveying speed V1a, and the front side of the electrode strip 200 has processing areas 210 spaced apart along the conveying direction. While the electrode strip 200 is conveyed at the first conveying speed V1a, an adsorption platform 120 is positioned opposite the back side of the processing areas and moves along the conveying direction of the electrode strip 200 at a first movement speed V2a, wherein the first movement speed V2a is the same as the first conveying speed V1a, so that the adsorption platform 120 and the electrode strip 200 move synchronously. Simultaneously, while the electrode strip 200 is conveyed at the first conveying speed V1a, a processing mechanism 130 processes the electrode strip 200 on the adsorption platform 120 at a flight processing speed V3, wherein the flight processing speed V3 is the same as the first conveying speed V1a, so that the processing mechanism 130 processes the electrode strip 200 synchronously.

[0080] Compared with the prior art, the electrode processing system 100 and method provided in this embodiment of the invention, through synchronous control, can utilize the adsorption platform 120 to move synchronously with the electrode strip 200, and utilize the processing mechanism to process the electrode strip 200 synchronously. This enables the electrode strip 200 to be processed while maintaining transportation, and enables the electrode strip 200 to be processed in flight without stopping, which greatly shortens the processing time and improves the processing efficiency.

[0081] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
