Description

Technical Field

[0001] This application relates to the field of solid-state battery manufacturing equipment technology, specifically to a frame material strip preparation mechanism and a solid-state battery sheet making apparatus. Background Technology

[0002] With the continuous advancement of technology and the increasing demands of people, battery technology is also constantly evolving. Among them, solid-state batteries are a new type of battery technology that uses a solid electrolyte instead of a liquid electrolyte. Compared with traditional liquid batteries, solid-state batteries have advantages such as higher energy density, faster charging speed, better safety performance, and longer lifespan, and have attracted widespread attention.

[0003] In existing technologies, solid-state batteries generally include a positive electrode, a negative electrode, a solid electrolyte, and a frame. The process requires first cutting the positive and negative electrode sheets, solid electrolyte, and frame into sheets, and then stacking these sheets on a stacking table to form a solid-state battery cell. However, existing solid-state battery manufacturing equipment has low sheet-forming efficiency, which cannot match the stacking efficiency of the stacking process, resulting in low overall equipment production efficiency and an inability to meet capacity requirements.

[0046] Please see Figures 1 to 7 This application provides a solid-state battery fabrication apparatus, including a composite mechanism 10, a fabrication mechanism 20, and a frame strip preparation mechanism 30.

[0047] The frame material preparation mechanism 30 is used to prepare frame material B. The frame material preparation mechanism 30 includes a first unwinding assembly 31, a second unwinding assembly 33, and a composite die-cutting assembly 35. The first unwinding assembly 31 is used to unwind and output the frame material B3. The second unwinding assembly 33 is used to unwind and output the release film B1. The composite die-cutting assembly 35 is arranged downstream of the first unwinding assembly 31 and the second unwinding assembly 33, and is used to composite the frame material B3 and the release film B1, and to die-cut the passing frame material B3 into frames B2, thereby forming the frame material B. The frame material B includes the release film B1 and multiple frames B2 adhered to the same side of the release film B1, and the multiple frames B2 are arranged sequentially along the length direction of the release film B1.

[0048] The composite assembly 10 includes an electrode unwinding assembly 11, a frame unwinding assembly 12, and a strip composite assembly 13. Both the electrode unwinding assembly 11 and the frame unwinding assembly 12 are arranged upstream of the strip composite assembly 13. The electrode unwinding assembly 11 unwinds and outputs electrode strip A to the strip composite assembly 13. The frame unwinding assembly 12 unwinds and outputs frame strip B, prepared by the frame strip preparation mechanism, to the strip composite assembly 13. Both sides of the electrode strip A are provided with a solid electrolyte layer. The strip composite assembly 13 roll-composites the passing electrode strip A and frame strip B to form a composite strip C. It should be noted that the electrode strip A can be a negative electrode strip; however, in other embodiments it can also be a positive electrode strip, which is not limited here.

[0049] The electrode fabrication mechanism 20 includes an electrode tab cutting assembly 21 and a cutting assembly 22. The electrode tab cutting assembly 21 is located downstream of the composite material assembly 13 and is used to cut the electrode strip A on the passing composite material strip C to form electrode tabs on the electrode strip A. The cutting assembly 22 is located downstream of the electrode tab cutting assembly 21 and is used to cut the passing composite material strip C to form electrode sheet material D. The electrode sheet material D includes a laminated frame, a solid electrolyte layer, an electrode, and a solid electrolyte layer.

[0050] Thus, the composite die-cutting assembly 35 combines the frame material strip B3 and the release film B1, and then die-cuts the frame material strip B3 into a frame B2 to form the frame material strip B. The material strip composite assembly 13 combines the electrode material strip A and the frame material strip B, and then the tab cutting assembly 21 cuts the composite material strip C to form the tab A1. Finally, the cutting assembly 22 cuts the composite material strip C to form the electrode sheet D. This avoids cutting and manufacturing the electrode sheet, solid electrolyte layer and frame separately, which helps to improve the sheet manufacturing efficiency and thus improve the overall production efficiency of the machine to better meet the production capacity requirements.

[0051] Please continue reading Figure 1 Specifically, in this embodiment, the composite die-cutting assembly 35 includes a second guide roller 352 and a die-cutting assembly 354. The frame material strip B3 unwound by the first unwinding assembly 31 and the release film B1 unwound by the second unwinding assembly 33 both pass around the second guide roller 352, thereby causing the frame material strip B3 and the release film B1 to be composited at the second guide roller 352 to form a frame material strip B. The die-cutting assembly 354 is arranged downstream of the second guide roller 352 and is used to die-cut the frame material strip B3 on the passing frame material strip B into frames B2, such that the frame material strip B includes a release film B1 and multiple frames B2 stacked on the same side of the release film B1, the multiple frames B2 being arranged sequentially along the length direction of the release film B1.

[0052] Furthermore, the frame material strip preparation mechanism also includes a first steering roller 351 and a third steering roller 353 respectively arranged upstream and downstream of the second steering roller 352. The first steering roller 351 is used for the frame material strip b3 to pass through, and the die-cutting assembly 354 is arranged between the second steering roller 352 and the third steering roller 352. The first steering roller 351, the second steering roller 352, and the third steering roller 353 are arranged sequentially at intervals along a predetermined direction X. In this way, the first steering roller 351 is used to turn the frame material strip B3, and the second steering roller 352 is used to turn the release film B1, so that the frame material strip B3 and the release film B1 are bonded to each other at the second steering roller 352 (i.e., they are combined to form the frame material strip B), and the frame material strip B3 on the frame material strip B is die-cut into the frame B2 when it passes through the die-cutting assembly 354.

[0053] Furthermore, the frame material preparation mechanism 30 also includes a winding assembly 37. This winding assembly 37 is arranged downstream of the third steering roller 353 and is used to wind up the frame material B to form a frame roll. This frame roll can be transferred manually, automatically, or semi-automatically to the frame unwinding assembly 12, allowing the frame unwinding assembly 12 to unwind and output the frame material B downstream.

[0054] It should be noted that, please refer to Figure 2 In other embodiments, the frame-in-lined tape B3 unwound by the first unwinding assembly 31 includes a frame film layer B31 and a release film layer B32. Therefore, the tape passing through the die-cutting assembly 354 includes a release film layer B32, a frame film layer B31, and a release film B1 stacked sequentially. The die-cutting assembly 354 cuts the release film layer B32 and the frame film layer B31 of the passing tape, cutting the frame film layer B31 into a frame B2 and waste material. In order to remove the waste material and the release film layer B32 from the release film B1 (leaving only the frame B2 on the release film B1), the frame-in-lined tape preparation mechanism also includes a waste material winding assembly 38, which is arranged between the downstream of the die-cutting assembly 354 and the upstream of the third steering roller 353, for winding the release film layer B32 and the aforementioned waste material of the frame-in-lined tape B3.

[0055] Specifically, in this embodiment, the waste material winding assembly 38 includes a tape unwinding component 381, a fourth steering roller 382, ​​and a tape winding component 383. The fourth steering roller 382 is positioned downstream of the die-cutting assembly 354 and upstream of the third steering roller 353, such that the tape after die-cutting by the die-cutting assembly 354 passes sequentially through the fourth steering roller 382 and the third steering roller 353. The tape unwinding component 381 unwinds the tape E onto the fourth steering roller 382, ​​and the fourth steering roller 382 presses the wound tape E against the passing tape, causing the tape E to adhere to the release film layer B32 and waste material from the passing tape. Consequently, the release film layer B32 and waste material move with the tape E towards the tape winding component 383 and separate from the release film B1. The tape winding component 383 winds up the tape E wound around the fourth steering roller 382, ​​as well as the release film layer B32 and waste material adhered to the tape E.

[0056] Furthermore, two fourth steering rollers 382 are provided, which are arranged at intervals along the conveying direction of the release film B1. The tape unwinding unit 381 unwinds the tape E onto one of the upstream fourth steering rollers 382. The tape E passes sequentially around the two fourth steering rollers 382 and is then wound up by the tape winding unit 383. The tape E passing between the two fourth steering rollers 382 contacts the release film layer B32 and waste material of the passing material, thereby adhering to the release film layer B32 and the waste material, achieving the purpose of removing the waste material and the release film layer B32 from the release film B1.

[0057] It should be noted that the lamination of the adhesive frame material strip B3 and the release film B1 using the second steering roller 352 is not limited to the embodiments described above. In other embodiments, the lamination of the adhesive frame material strip B3 and the release film B1 can also be achieved by roller pressing. For details, please refer to [link to relevant documentation]. Figure 3 The composite die-cutting assembly 35 includes pressure rollers 358 and a die-cutting assembly 354. Two pressure rollers 358 are arranged opposite each other. A composite channel F is formed between the two pressure rollers 358 for the frame material strip B3 and release film B1 to pass through. The frame material strip B3 unwound from the first unwinding assembly 31 and the release film B1 unwound from the second unwinding assembly 33 pass together through the composite channel F between the two pressure rollers 358. The two pressure rollers 358 jointly roll and press the frame material strip B3 and release film B1 passing through the composite channel F, causing the frame material strip B3 and release film B1 to composite and form the frame material strip B. The die-cutting assembly 354 is arranged downstream of the two pressure rollers 358 and is used to die-cut the frame material strip B3 on the passing frame material strip B into frame B2, such that the frame material strip B includes a release film B1 and a plurality of frames B2 stacked on the same side of the release film B1, the plurality of frames B2 being arranged sequentially along the length direction of the release film B1.

[0058] Please continue reading Figures 4 to 7 Specifically, in the embodiment, the adhesive frame unwinding assembly 12 outputs an adhesive frame strip B including a release film B1 and several adhesive frames B2 disposed on the same side of the release film B1, with each adhesive frame B2 arranged sequentially along the length direction of the release film B1.

[0059] The composite mechanism 10 also includes a release film winding assembly 14, which is arranged between the downstream of the tape composite assembly 13 and the upstream of the tab cutting assembly 21, for winding the release film B1 on the composite tape C in the path, so that the composite tape C reaching the tab cutting assembly 21 does not contain the release film B1.

[0060] Furthermore, the release film winding assembly 14 includes a first guide roller 142, a first tension adjusting assembly 143, and a release film winding member 141. The first guide roller 142 is used to wind the release film B1 on the composite strip C. The release film winding member 141 is arranged downstream of the first guide roller 142 and is used to wind the release film B1 on the composite strip C that has passed through the first guide roller 142. The first tension adjusting assembly 143 is arranged between the downstream of the first guide roller 142 and the upstream of the release film winding member 141 and is used to adjust the tension of the release film B1 so that the tension of the release film B1 remains stable, so that the release film winding member 141 can stably wind the release film B1.

[0061] Optionally, the first tension adjustment assembly 143 includes a second guide roller 1431, a third guide roller 1433, and a first moving roller 1432. The second guide roller 1431 is arranged downstream of the first guide roller 142, the third guide roller 1433 is arranged downstream of the second guide roller 1431, the release film winding member 141 is arranged downstream of the third guide roller 1433, and the first moving roller 1432 is movably disposed between the second guide roller 1431 and the third guide roller 1433. Thus, after the release film B1 on the composite strip C separates from the composite strip C at the first guide roller 142, it sequentially passes through the second guide roller 1431, the first moving roller, and the third guide roller 1433, and is then wound up by the release film winding member 141. The first moving roller 1432 can move relative to the second passing roller 1431 and the third passing roller 1433, thereby causing the release film B1 to be tensioned or relaxed, that is, to adjust the tension of the release film B1 and ensure that the tension of the release film B1 remains stable.

[0062] It should be noted that the tension of the release film B1 can be adjusted by means of translation or oscillation, which is not limited here.

[0063] Please continue reading Figure 5 and Figure 7 As shown, in a specific embodiment, the composite mechanism 10 further includes a deviation correction component 17, which is arranged between the downstream of the electrode unwinding component 11 and the upstream of the strip composite component 13. The deviation correction component 17 is used to correct the deviation of the passing electrode strip A, so as to prevent the electrode strip A entering the strip composite component 13 from deviating from the frame strip B in the width direction.

[0064] Specifically, in this embodiment, the composite mechanism 10 further includes a fourth guide roller 161, a first tape-joining assembly 163, and a fifth guide roller 165. The fourth guide roller 161 and the fifth guide roller 165 are both arranged downstream of the electrode unwinding assembly 11 and upstream of the web-correcting assembly 17, and the first tape-joining assembly 163 is arranged between the fourth guide roller 161 and the fifth guide roller 165. Thus, the electrode strip A unwound from the electrode unwinding assembly 11 sequentially passes through the fourth guide roller 161, the first tape-joining assembly 163, the fifth guide roller 165, the web-correcting assembly 17, and the tape composite assembly 13. The fourth guide roller 161 and the fifth guide roller 165 are used to deflect the passing electrode strip A, ensuring that the electrode strip A between the fourth guide roller 161 and the fifth guide roller 165 passes through the first tape-joining assembly 163, so that a tape-joining operation can be performed at the first tape-joining assembly 163.

[0065] It should be noted that when the material roll on the electrode unwinding assembly 11 is used up and needs to be replaced, the electrode material strip A is first cut at the first splicing assembly 163, and the downstream cut end of the electrode material strip A is fixed by the first splicing assembly 163. Then, the empty material roll on the electrode unwinding assembly 11 is removed, and a new full material roll is loaded onto the electrode unwinding assembly 11. The starting end of the material strip on the full material roll is then pulled to the first splicing assembly 163, and bonded to the downstream cut end of the electrode material strip A fixed by the first splicing assembly 163 with adhesive tape, thus completing the splicing.

[0066] In a specific embodiment, the composite mechanism 10 further includes a second tension adjustment component 18. The second tension adjustment component 18 is arranged between the downstream of the electrode unwinding component 11 and the upstream of the correction component 17, and is used to adjust the tension of the electrode strip A so that the tension of the electrode strip A remains stable, so that the electrode strip A enters the strip composite component 13 with a certain tension, which is beneficial to improving the quality of strip composite.

[0067] Optionally, the second tension adjustment assembly 18 includes a sixth guide roller 181, a seventh guide roller 185, and a second motion roller 183. The sixth guide roller 181 is arranged downstream of the electrode unwinding assembly 11, the seventh guide roller 185 is arranged downstream of the sixth guide roller 181, the web guiding assembly 17 is arranged downstream of the seventh guide roller 185, and the second motion roller 183 is movably disposed between the sixth guide roller 181 and the seventh guide roller 185. Thus, the electrode strip A unwound from the electrode unwinding assembly 11 passes sequentially through the sixth guide roller 181, the second motion roller 183, the seventh guide roller 185, and the web guiding assembly 17. The second motion roller 183 can move relative to the sixth guide roller 181 and the seventh guide roller 185, thereby causing the passing electrode strip A to be tensioned or relaxed, that is, to adjust the tension of the electrode strip A and ensure that the tension of the electrode strip A remains stable.

[0068] It should be noted that the tension of the electrode strip A can be adjusted by means of translation or oscillation, which is not limited here.

[0069] Specifically, in this embodiment, the composite mechanism 10 further includes a first dust removal component 191 and a second dust removal component 192. Both the first dust removal component 191 and the second dust removal component 192 are arranged downstream of the electrode unwinding assembly 11 and upstream of the correction assembly 17. The first dust removal component 191 is used to remove dust from one side of the passing electrode strip A, and the second dust removal component 192 is used to remove dust from the other side of the passing electrode strip. Thus, by using the first dust removal component 191 and the second dust removal component 192 to remove dust from both sides of the electrode strip A, dust and other contaminants are avoided from remaining on the surface of the electrode strip A entering the strip composite assembly 13.

[0070] Specifically Figure 5In the illustrated embodiment, the electrode unwinding assembly 11, the fourth guide roller 161, the first tape joining assembly 163, the first dust removal assembly 191, the fifth guide roller 165, the sixth guide roller 181, the second motion roller 183, the seventh guide roller 185, the second dust removal assembly 192, and the web guiding assembly 17 are arranged sequentially from upstream to downstream. That is, the electrode strip A unwound from the electrode unwinding assembly 11 passes sequentially through the fourth guide roller 161, the first tape joining assembly 163, the first dust removal assembly 191, the fifth guide roller 165, the sixth guide roller 181, the second motion roller 183, the seventh guide roller 185, the second dust removal assembly 192, and the web guiding assembly 17, and then enters the strip composite assembly 13 for composite processing.

[0071] Specifically, in this embodiment, the composite material assembly 13 includes a first composite roller 131 and a second composite roller 133, both of which are rotatable around their own axes. The first composite roller 131 and the second composite roller 133 are arranged parallel to each other and opposite to each other, forming a composite channel through which the electrode strip A and the frame strip B pass. Thus, the first composite roller 131 and the second composite roller 133 jointly compress the electrode strip A and the frame strip B passing between them, causing the electrode strip A and the frame strip B to adhere to each other and form a composite material strip C. It should be noted that the frame strip B can be a single-layer frame or a double-layer frame; this is not limited here.

[0072] Furthermore, the strip composite assembly 13 also includes an adjustment assembly 135, which is connected to the second composite roller 133. The adjustment assembly 135 is used to move the second composite roller 133 closer to or further away from the first composite roller 131, thereby adjusting the width of the composite channel and thus adjusting the pressure on the electrode strip A and the frame strip B passing through the composite channel.

[0073] It should be noted that the first electrode strip A and / or the frame strip B have a bonding adhesive. This bonding adhesive can be a pressure-sensitive adhesive or a heat-sensitive adhesive, and is not limited here. The first composite roller 131 and the second composite roller 133 can be room temperature rollers or hot-press rollers, as long as they can achieve the bonding of the electrode strip A and the frame strip B, and are not limited here.

[0074] Please see Figure 6 and Figure 7As shown in the embodiments of this application, the film-making mechanism 20 further includes a first visual inspection component 24 and a second visual inspection component 25. Both the first visual inspection component 24 and the second visual inspection component 25 are arranged downstream of the release film winding assembly 14 and upstream of the electrode cutting assembly 21, so that the first visual inspection component 24 and the second visual inspection component 25 can respectively perform visual inspection on both sides of the passing composite strip C, that is, perform surface defect detection on both sides of the composite strip C. Thus, if a surface defect is detected in a certain section of the composite strip C, the defective electrode sheet D will be rejected after that section is subsequently cut to form the electrode sheet D. It should be noted that both the first visual inspection component 24 and the second visual inspection component 25 can be cameras.

[0075] In a specific embodiment, the sheet-making mechanism 20 further includes a main drive conveying assembly 23. This main drive conveying assembly 23 is positioned downstream of the tab cutting assembly 21 and upstream of the cutting assembly 22, and is used to pull the composite material strip C towards the cutting assembly 22. Thus, each time the main drive conveying assembly 23 pulls the composite material strip C a certain distance towards the downstream cutting assembly 22, it ensures that the cutting position of the cutting assembly 22 is accurate each time, and that the resulting electrode sheet material D has a consistent size.

[0076] In a specific embodiment, the electrode fabrication mechanism 20 further includes a feeding assembly 26, a third vision inspection assembly 28, and a fourth vision inspection assembly 29. The feeding assembly 26 is located downstream of the cutting assembly 22 and is used to receive the electrode sheet material D formed by cutting the composite strip C by the cutting assembly 22. The third vision inspection assembly 28 and the fourth vision inspection assembly 29 are both arranged on the feeding path of the feeding assembly 26, enabling both the third vision inspection assembly 28 and the fourth vision inspection assembly 29 to perform visual inspection of the electrode sheet material D on the feeding assembly 26.

[0077] Furthermore, the third vision inspection component 28 is used to perform dimensional inspection on the electrode sheet material D on the feeding assembly 26 to determine whether the dimensions of the electrode sheet material D are qualified. The fourth vision inspection component 29 is used to perform surface defect inspection on the electrode sheet material D on the feeding assembly 26 to determine whether surface defects exist in the electrode sheet material D. It should be noted that both the third vision inspection component 28 and the fourth vision inspection component 29 can be cameras.

[0078] Optionally, the conveying assembly 26 is a vacuum belt conveyor. In actual use, firstly, the main drive conveying assembly 23 pulls the composite material belt C a certain distance towards the cutting assembly 22, so that the starting end of the composite material belt C reaches the belt of the conveying assembly 26 and is attracted and fixed on the belt; then, the cutting assembly 22 cuts the composite material belt C. At this time, part of the electrode sheet material D formed by the cutting is attracted and fixed on the belt of the conveying assembly 26. Then, the belt of the conveying assembly 26 moves downstream, thereby driving the electrode sheet material D to move downstream together.

[0079] In a specific embodiment, the electrode fabrication mechanism 20 further includes a third dust removal component 27, which is arranged on the feeding path of the feeding component 26, so that the third dust removal component 27 can remove dust from the electrode sheet material D on the feeding component 26 to ensure that the cleanliness of the electrode sheet material D on the feeding component 26 meets the process requirements.

[0080] Specifically Figure 6 In the illustrated embodiment, the third dust removal component 27, the third visual inspection component 28, and the fourth visual inspection component 29 are arranged sequentially along the feeding direction of the feeding component 26. That is, the electrode sheet D on the feeding component 26 passes through the third dust removal component 27 for dust removal, the third visual inspection component 28 for size inspection, and the fourth visual inspection component 29 for surface defect inspection.

[0081] Based on the above-described adhesive frame tape preparation mechanism, this application also provides a method for preparing adhesive frame tape. Please refer to [link to relevant documentation]. Figure 1 and Figure 8 The method for preparing the adhesive frame tape includes the following steps:

[0082] S10. Unwinding output of the rubber frame feeder belt B3 and unwinding output of the release film B1. Specifically, the first unwinding assembly 31 uses the downstream first guide roller 351 to unwind and output the rubber frame feeder belt B3, and the second unwinding assembly 33 uses the downstream second guide roller 352 to unwind and output the release film B1.

[0083] S20. The frame material strip B3 and the release film B1 are combined to form the frame material strip B. Specifically, the frame material strip B3 and the release film B1 are bonded together under the steering action of the first steering roller 351 and the second steering roller 352 to form the frame material strip B.

[0084] S30. Die-cut the frame material strip B to form a frame B2 that is attached to the same side of the release film. At this time, the frame material strip B includes a release film B1 and multiple frames B2 attached to the same side of the release film B1, and each frame B2 is arranged sequentially along the length of the release film B1.

[0085] S40. The frame material strip B is wound up using the winding assembly 37 to form a frame material roll.

[0086] S50. The frame material roll on the take-up assembly 37 is transferred to the frame unwinding assembly 12 by manual, automatic or semi-automatic means, so that the frame unwinding assembly 12 can unwind and output the frame material strip B downstream.

[0087] In this way, the frame material strip B3 and the release film B1 are laminated, and the frame material strip B3 is die-cut into frame B2 to form frame material strip B. Subsequently, the electrode material strip A and the frame material strip B can be laminated first, and then the tab A1 can be cut on the laminated material strip C. The laminated material strip C is then cut to form the electrode sheet D. This avoids cutting and manufacturing the electrode sheet, solid electrolyte layer and frame separately, which helps to improve the sheet manufacturing efficiency and thus improve the overall production efficiency of the machine to better meet the production capacity requirements.

[0088] Furthermore, the unwound material strip B3 from the first unwinding assembly 31 includes a frame film layer B31 and a release film layer B32. Therefore, the strip passing through the die-cutting assembly 354 includes a release film layer B32, a frame film layer B31, and a release film B1 stacked sequentially. The die-cutting assembly 354 cuts the release film layer B32 and the frame film layer B31 of the passing strip, cutting the frame film layer B31 into a frame B2 and waste material. In order to remove the waste material and the release film layer B32 from the release film B1 (leaving only the frame B2 on the release film B1), the following steps are further included between step S30 and step S40:

[0089] The adhesive tape E is used to pick up the release film layer B32 and the waste material formed by the die-cutting assembly 354. Specifically, the tape unwinding unit 381 unwinds the tape E to the fourth guide roller 382. The fourth guide roller 382 presses the tape E against the incoming material tape B3 of the passing frame, so that the tape E picks up the release film layer B32 and the waste material. The tape winding unit 383 winds up the tape E that has passed through the fourth guide roller 382, ​​as well as the release film layer B32 and the waste material stuck on the tape E.

[0090] Based on the above-described solid-state battery fabrication apparatus, this application also provides a solid-state battery fabrication device. This solid-state battery fabrication device includes a stacking device and the solid-state battery fabrication apparatus as described in any of the above embodiments. The solid-state battery fabrication apparatus is used to fabricate the above-described electrode sheet D. The stacking device is used to stack the electrode sheet D to form a solid-state battery.

[0091] It should be noted that when the electrode in electrode sheet D is a negative electrode, the stacking device is used to stack electrode sheet D and the positive electrode to form a solid-state battery. When the electrode in electrode sheet D is a positive electrode, the stacking device is used to stack electrode sheet D and the negative electrode to form a solid-state battery.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
