[0001] The present application relates to the field of battery technology, and in particular to a bagging device, a bagging method and battery manufacturing equipment. Background Art

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages in energy conservation and environmental protection. For electric vehicles, battery technology is an important factor in their development.

[0003] In the manufacturing process of solid-state batteries, the packaging of solid-state battery cells is an important process in the battery manufacturing process. During the packaging of solid-state battery cells in aluminum-plastic film bags, the insulating glue around the solid-state battery cells may be scratched by the aluminum-plastic film bags, resulting in damage to the insulating layer around the solid-state battery cells, affecting the performance of the battery. Summary of the invention

[0004] The present application provides a bagging device, a bagging method and a battery manufacturing device, which can reduce the risk of scratching of solid-state battery cells with aluminum-plastic film bags when being bagged, and improve the reliability of solid-state battery cells.

[0005] This application is achieved through the following technical solutions:

[0006] In a first aspect, an embodiment of the present application provides a bagging device, which is used to place a solid-state battery cell into an aluminum-plastic film bag, wherein one end of the aluminum-plastic film bag in a first direction has an open bag opening, and the bagging device comprises a positioning module and a bagging module, wherein the positioning module is used to position the aluminum-plastic film bag and open the bag opening of the aluminum-plastic film bag; the bagging module comprises a supporting member for carrying the solid-state battery cell, wherein the supporting member is movably arranged on the positioning module along a first direction so as to place the solid-state battery cell into the aluminum-plastic film bag from the bag opening; wherein the supporting member comprises a bottom plate and two side plates, wherein the bottom plate has a bearing surface for carrying the solid-state battery cell, and the two side plates are respectively arranged on opposite sides of the bearing surface in a second direction, and the side plates have a first side away from the bearing surface; when the solid-state battery cell is placed on the bottom plate, the first side extends beyond the setting of the solid-state battery cell, and the first direction is perpendicular to the second direction.

[0007] In the technical solution of the embodiment of the present application, the aluminum-plastic film bag is adopted as a bag body structure with an open end and a bag opening. Through the setting of the positioning module, the positioning module can position the aluminum-plastic film bag and open the bag opening of the aluminum-plastic film bag, so as to facilitate the solid-state battery monomer to enter the aluminum-plastic film bag. Through the setting of the bag entry module, the supporting member in the bag entry module can move along the first direction relative to the positioning module. After the solid-state battery monomer is placed on the supporting member, the supporting member is moved along the first direction. The supporting member can carry the solid-state battery monomer from the bag opening of the aluminum-plastic film bag into the aluminum-plastic film bag, completing the bag entry process of the solid-state battery monomer, and the operation is convenient and quick. More importantly, the supporting member includes a bottom plate and two side plates, and the two side plates are respectively arranged on both sides of the second direction of the bottom plate. When the solid-state battery cell is placed on the bottom plate, the first side is arranged beyond the solid-state battery cell. In this way, in the process of the supporting member carrying the solid-state battery cell into the aluminum-plastic film bag, the side plates can replace the solid-state battery cell to contact the inner wall of the aluminum-plastic film bag. The side plates can protect the solid-state battery cell, and the solid-state battery cell will not contact and scratch the inner wall of the aluminum-plastic film bag, which can effectively reduce the risk of scratching the solid-state battery cell with the aluminum-plastic film bag when entering the bag, and correspondingly reduce the risk of subsequent short circuit of the solid-state battery cell caused by damage to the insulating glue around the solid-state battery cell, thereby improving the reliability of the solid-state battery cell.

[0008] According to some embodiments of the present application, when the solid-state battery cell is placed on the bottom plate, the amount by which the first side protrudes beyond the solid-state battery cell is not less than 2 mm.

[0009] In the above scheme, the protrusion of the first side beyond the solid-state battery cell is set to be no less than 2 mm. The first side of the side plate can effectively protect the solid-state battery cell, reduce the risk of contact or even scratch between the solid-state battery cell and the inner wall of the aluminum-plastic film bag, and improve the reliability and stability of the solid-state battery cell entering the bag.

[0010] According to some embodiments of the present application, the side panel and the bottom panel are detachably connected.

[0011] In the above scheme, the side panels are detachably connected to the bottom panel, and side panels of different heights can be replaced according to different models of solid-state battery cells. This scheme has a wider scope of application and can meet the bagging requirements of different models of solid-state battery cells.

[0012] According to some embodiments of the present application, a negative pressure adsorption member is provided on the bottom plate, and the negative pressure adsorption member is used to adsorb and position the solid-state battery cell.

[0013] In the above scheme, a negative pressure adsorption component is provided on the bottom plate. After the solid-state battery cell is placed on the bottom plate, the negative pressure adsorption component can adsorb and position the solid-state battery cell. In the process of the supporting component carrying the solid-state battery cell into the bag, the risk of relative movement between the solid-state battery cell and the supporting component can be further reduced, so that the solid-state battery cell can be bagged more accurately.

[0014] According to some embodiments of the present application, the aluminum-plastic film bag has a first wall and a second wall relatively distributed in the thickness direction; the positioning module includes a frame, a first suction plate and a second suction unit, the first suction plate is arranged on the frame, and the first suction plate has a first suction surface for suction positioning with the first wall; the second suction unit is arranged on the frame, and the second suction unit includes a second suction plate, and the second suction plate has a second suction surface for suction positioning with the second wall; the second suction unit and the first suction plate are distributed on the frame at intervals along a third direction; wherein, at least one of the first suction plate and the second suction plate is movably arranged on the frame along a vertical direction, so that the second suction plate and the first suction plate can approach or move away from each other, and the third direction, the first direction and the second direction are perpendicular to each other.

[0015] In the above scheme, the positioning module is in the form of a first suction plate and a second suction plate, and the first suction plate and the second suction plate can respectively adsorb the first wall and the second wall on both sides of the aluminum-plastic film bag in the thickness direction to complete the adsorption positioning of the aluminum-plastic film bag. At least one of the first suction plate and the second suction plate is movably arranged on the frame in the vertical direction, so that the first suction plate and the second suction plate move relative to each other, driving the first wall and the second wall of the aluminum-plastic film bag to move away from each other, thereby opening the bag mouth of the aluminum-plastic film bag, with a simple structure and high positioning stability for the aluminum-plastic film bag.

[0016] According to some embodiments of the present application, the bag entering module also includes a first movable seat and a first linear drive assembly, the first movable seat is slidably disposed on the frame along a first direction, and the supporting member is connected to the first movable seat; the first linear drive assembly is disposed on the frame, and the first linear drive assembly is used to drive the first movable seat to move along the first direction.

[0017] In the above scheme, through the arrangement of the first linear drive component and the first movable seat, the supporting member is arranged on the first movable seat. The first linear drive component can provide power to drive the first movable seat to move along the first direction, thereby driving the supporting member to enter the aluminum-plastic film bag from the bag opening of the aluminum-plastic film bag to complete the bagging of the solid-state battery monomer. There is no need for manual operation to complete the movement of the supporting member into the bag. The movement accuracy of the supporting member is high, which reduces the workload of the staff and has a high degree of automation.

[0018] According to some embodiments of the present application, the bag entering module also includes a first flipping component, which is arranged between the first movable seat and the supporting member, and the first flipping component is used to drive the supporting member to flip; the second adsorption unit also includes a second flipping component, which is arranged between the frame and the second suction plate, and the second flipping component is used to drive the second suction plate to flip, and the rotation axis of the supporting member and the second suction plate are collinear.

[0019] In the above scheme, through the arrangement of the first flip assembly and the second flip assembly, after the supporting member sends the solid-state battery monomer into the aluminum-plastic film bag, the first suction plate can give way or the second suction plate can be raised synchronously with the supporting member to form a flipping space after the first suction plate gives way. Then, the first flip assembly and the second flip assembly can flip simultaneously to flip the supporting member and the second suction plate 180° together, so that the gravity of the aluminum-plastic film bag and the solid-state battery monomer in the aluminum-plastic film bag falls on the second suction plate. In the process of pulling the supporting member out of the aluminum-plastic film bag, the supporting member is not easy to contact the solid-state battery monomer, nor will the solid-state battery monomer be displaced due to the movement of the supporting member during the pulling-out process, thereby ensuring that the position of the solid-state battery monomer in the aluminum-plastic film bag will not change, and the supporting member can be pulled out of the aluminum-plastic film bag more easily.

[0020] According to some embodiments of the present application, the first suction plate is fixedly disposed on the frame; the second suction plate and the supporting member are movably disposed on the frame along the vertical direction to approach or move away from the first suction plate.

[0021] In the above scheme, the first suction plate is fixedly arranged on the frame, and the second suction plate and the supporting member are movably arranged on the frame in the vertical direction to be close to or away from the first suction plate. In this way, when the bag mouth of the aluminum-plastic film bag is opened, it is only necessary to move the second suction plate relative to the first suction plate in a direction away from the first suction plate to open the bag mouth of the aluminum-plastic film bag. When the supporting member is withdrawn from the aluminum-plastic film bag, the second suction plate and the supporting member can be turned over synchronously, so that the supporting member is turned over to the upper side of the solid-state battery cell, and the second suction plate provides a supporting effect for the aluminum-plastic bag film, which facilitates the separation of the supporting member from the aluminum-plastic film bag.

[0022] According to some embodiments of the present application, the second adsorption unit includes a second linear drive component and a second movable seat, and the second linear drive component is arranged on the frame; the second movable seat is connected to the second linear drive component, and the second flipping component is arranged between the second movable seat and the second suction plate, and the second linear drive component is used to drive the second suction plate to move in a vertical direction to approach or move away from the first suction plate.

[0023] In the above scheme, through the arrangement of the second linear drive component and the second movable seat, the second flipping component is arranged between the second movable seat and the second suction plate. The second linear drive component can provide power to drive the second movable seat to move in the vertical direction, thereby driving the second suction plate to approach or move away from the first suction plate. There is no need for manual labor to complete the lifting and lowering action of the second suction plate, which reduces the workload of the staff, has a high degree of automation, and the movement accuracy of the second suction plate is high.

[0024] According to some embodiments of the present application, the bag entering module also includes a first lifting seat and a third linear drive assembly, the first linear drive assembly is arranged on the first lifting seat; the third linear drive assembly is arranged on the frame, and the third linear drive assembly is used to drive the first lifting seat to move in a vertical direction relative to the frame.

[0025] In the above scheme, through the arrangement of the third linear drive component and the first lifting seat, the first linear drive component is arranged on the first lifting seat, and the third linear drive component can provide power to drive the first linear drive component and the first moving seat to move in the vertical direction, thereby driving the supporting member to move in the vertical direction together with the second suction plate, providing a flipping space for the flipping of the supporting member and the second suction plate, and there is no need for manual labor to complete the lifting action of the first lifting seat, which reduces the workload of the staff and has a high degree of automation.

[0026] In a second aspect, an embodiment of the present application further provides a battery manufacturing device, the battery manufacturing device comprising the bagging device of any of the aforementioned embodiments.

[0027] On the third aspect, an embodiment of the present application also provides a bagging method, which is based on the bagging device of any of the aforementioned embodiments, and the bagging method includes: placing a solid-state battery cell on a supporting member; opening the bag opening of the aluminum-plastic film bag, allowing the supporting member to move along a first direction, and the supporting member carries the solid-state battery cell into the aluminum-plastic film bag from the bag opening of the aluminum-plastic film bag; flipping the supporting member and the aluminum-plastic film bag together by 180°, and withdrawing the supporting member from the aluminum-plastic film bag.

[0028] In the above scheme, after the positioning module opens the bag opening of the aluminum-plastic film bag, the supporting member moves along the first direction, and the supporting member carries the solid-state battery monomer from the bag opening of the aluminum-plastic film bag into the aluminum-plastic film bag. The side plate of the supporting member can protect the solid-state battery monomer and reduce the risk of scratches between the solid-state battery monomer and the inner wall of the aluminum-plastic film bag. By flipping the supporting member and the aluminum-plastic film bag 180 degrees, the supporting member is located on the upper side of the solid-state battery monomer, which facilitates the support member to be withdrawn from the aluminum-plastic film bag.

[0029] According to some embodiments of the present application, the supporting member is withdrawn from the aluminum-plastic film bag, including moving the supporting member and the solid-state battery cell relative to each other in a third direction so that a gap is formed between the supporting member and the solid-state battery cell in the third direction, and then withdrawing the supporting member from the aluminum-plastic film bag.

[0030] In the above scheme, when the supporting member is withdrawn from the aluminum-plastic film bag, although the supporting member is located on the upper side of the solid-state battery cell after being flipped 180°, in order to further reduce the risk of relative friction with the solid-state battery cell or displacement of the solid-state battery cell when the supporting member is withdrawn from the aluminum-plastic film bag along the first direction, the supporting member and the solid-state battery cell can be moved relative to each other in the third direction, so that a gap is formed between the supporting member and the solid-state battery cell in the third direction. In this way, the supporting member will not contact the solid-state battery cell during the process of pulling the supporting member out of the aluminum-plastic film bag.

[0031] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0044] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0045] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0047] The term "multiple" as used in the present application refers to more than two (including two). Similarly, the term "multiple groups" refers to more than two groups (including two groups), and the term "multiple sheets" refers to more than two sheets (including two sheets).

[0048] A battery cell generally includes an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of the battery cell, active ions (such as lithium ions) are embedded and removed between the positive electrode and the negative electrode. The separator is set between the positive electrode and the negative electrode to prevent the positive and negative electrodes from short-circuiting, while allowing active ions to pass through.

[0049] From the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0050] The development of battery technology must take into account multiple design factors at the same time, such as performance parameters such as energy density, charge and discharge rate, and also the reliability of the battery.

[0051] At present, in the manufacturing process of solid-state batteries, solid-state battery monomers need to be packaged in bags before the warm isostatic pressing process. The battery cell packaging in the prior art generally adopts the method of punching holes in aluminum-plastic film for packaging, that is, the aluminum-plastic film in the prior art is different from the aluminum-plastic film bag in this application document. The aluminum-plastic film in the prior art is a single-layer aluminum-plastic film, and the method of bagging the battery cell is: first, the aluminum-plastic film is punched with a punching mold to form two first and second pits spaced apart on the surface of the aluminum-plastic film, and the battery cell is placed in the first pit of the aluminum-plastic film, and then folded along the center line of the aluminum-plastic film, and the second pit is buckled on the battery cell, and then the folded aluminum-plastic film is top-sealed once, top-sealed twice, and side-sealed in sequence. The battery cell bagging process and process in the prior art are relatively cumbersome, and it is necessary to punch holes on the aluminum-plastic film in advance, and then the battery cell is placed in the pit and then top-sealed and side-sealed multiple times. If the solid-state battery cells are directly packaged in aluminum-plastic film bags, the insulating glue around the solid-state battery cells may be scratched by the aluminum-plastic film bags, causing damage to the insulating layer around the solid-state battery cells and affecting the performance of the battery.

[0052] In view of this, in order to solve the problem of scratching the solid-state battery monomer against the aluminum-plastic film bag when being bagged, some embodiments of the present application provide a bagging device, which is used to place the solid-state battery monomer into the aluminum-plastic film bag, and one end of the aluminum-plastic film bag in a first direction has an open bag opening, and the bagging device includes a positioning module and a bagging module, the positioning module is used to position the aluminum-plastic film bag and open the bag opening of the aluminum-plastic film bag; the bagging module includes a supporting member for carrying the solid-state battery monomer, and the supporting member is movably arranged on the positioning module along the first direction to place the solid-state battery monomer into the aluminum-plastic film bag from the bag opening; wherein the supporting member includes a bottom plate and two side plates, the bottom plate has a bearing surface for carrying the solid-state battery monomer, the two side plates are respectively arranged on opposite sides of the bearing surface in a second direction, and the side plate has a first side away from the bearing surface; when the solid-state battery monomer is placed on the bottom plate, the first side exceeds the setting of the solid-state battery monomer, and the first direction is perpendicular to the second direction.

[0053] In such a bagging device, when the solid-state battery cell is placed on the bottom plate, the first side is arranged beyond the solid-state battery cell. In this way, in the process of the supporting member carrying the solid-state battery cell into the aluminum-plastic film bag, the side plate can replace the solid-state battery cell to contact the inner wall of the aluminum-plastic film bag. The side plate can protect the solid-state battery cell. The solid-state battery cell will not contact and scratch the inner wall of the aluminum-plastic film bag, which can effectively reduce the risk of scratching the solid-state battery cell with the aluminum-plastic film bag when entering the bag, and correspondingly reduce the risk of subsequent short circuit of the solid-state battery cell caused by damage to the insulating glue around the solid-state battery cell, thereby improving the reliability of the solid-state battery cell.

[0054] The present application embodiment provides a bagging device, please refer to Figures 1 to 8The bagging device 100 is used to place the solid-state battery cell 200 into the aluminum-plastic film bag 300. Figure 2 As shown, one end of the aluminum-plastic film bag 300 in the first direction X has an open bag opening 301 . The bagging device 100 includes a positioning module 10 and a bagging module 20. The positioning module 10 is used to position the aluminum-plastic film bag 300 and open the bag opening 301 of the aluminum-plastic film bag 300. The bagging module 20 includes a supporting member 21 for carrying the solid-state battery cell 200. The supporting member 21 is movably arranged on the positioning module 10 along a first direction X so as to place the solid-state battery cell 200 into the aluminum-plastic film bag 300 from the bag opening 301. The supporting member 21 includes a bottom plate 211 and two side plates 212. The bottom plate 211 has a supporting surface 214 for carrying the solid-state battery cell 200. The two side plates 212 are respectively arranged on opposite sides of the supporting surface 214 in a second direction Y. The side plates 212 have a first side 2121 away from the supporting surface 214. When the solid-state battery cell 200 is placed on the bottom plate 211, the first side 2121 is arranged beyond the solid-state battery cell 200, and the first direction X is perpendicular to the second direction Y.

[0055] The aluminum-plastic film bag 300, also known as the isostatic film bag, needs to be packaged on the solid-state battery cell 200 before the solid-state battery cell 200 undergoes the warm isostatic pressing process, so as to isolate the solid-state battery cell 200 from the liquid medium during the warm isostatic pressing process.

[0056] The solid-state battery cell 200 is a solid-state battery core. The insulating glue around the solid-state battery cell 200 is UV printed glue, which can insulate and support the solid-state battery cell 200. The insulating glue around the solid-state battery cell 200 is relatively fragile. When the insulating glue around the solid-state battery cell 200 is scratched and damaged, the solid-state battery cell 200 has the risk of insulation failure, which affects the reliability of the solid-state battery cell 200.

[0057] The positioning module 10 is a positioning tool. The function of the positioning module 10 is to position the aluminum-plastic film bag 300 and open the bag opening 301 of the aluminum-plastic film bag 300. When the bagging module 20 carries the solid-state battery cell 200 into the aluminum-plastic film bag 300, the positioning module 10 can open the bag opening 301 of the aluminum-plastic film bag 300 in advance and maintain the relative position of the aluminum-plastic film bag 300, ensuring that the aluminum-plastic film bag 300 will not move relative to the positioning module 10 during the process of the bagging module 20 carrying the solid-state battery cell 200 into the aluminum-plastic film bag 300.

[0058] The structure of the positioning module 10 can be various. For example, the positioning module 10 can include two suction cups, which are respectively located on both sides of the thickness direction of the aluminum-plastic film bag 300. The two suction cups are in contact with both sides of the thickness direction of the aluminum-plastic film bag 300. The two suction cups provide negative pressure adsorption force to adsorb both sides of the thickness direction of the aluminum-plastic film bag 300, and at least one of the two suction cups moves along the thickness direction of the aluminum-plastic film bag 300, thereby moving at least one side panel 212 of the aluminum-plastic film bag 300 in the thickness direction away from each other, thereby opening the bag mouth 301 of the aluminum-plastic film bag 300.

[0059] Of course, the positioning module 10 may also include a suction cup and a clamping cylinder. The suction cup is used to carry and position the aluminum-plastic film bag 300. The clamping cylinder is connected to two clamping parts, which are respectively located on the left and right sides of the aluminum-plastic film bag 300. The operation of the clamping cylinder can drive the two clamping parts to move toward each other to squeeze the left and right sides of the aluminum-plastic film bag 300 to open the bag mouth 301 of the aluminum-plastic film bag 300.

[0060] Alternatively, the positioning module 10 may further include a suction cup and an air blowing mechanism, wherein the suction cup is also used to carry and position the aluminum-plastic film bag 300, and the air outlet of the air blowing mechanism is aligned with the bag opening 301 of the aluminum-plastic film bag 300, and air is inflated toward the inner cavity of the aluminum-plastic film bag 300 to open the bag opening 301 of the aluminum-plastic film bag 300. The specific structure of the positioning module 10 may be determined according to actual conditions.

[0061] The supporting member 21 is movably arranged on the positioning module 10 along the first direction X. The supporting member 21 can be manually driven to move along the first direction X, or it can be electrically driven. The movement mode of the supporting member 21 can be determined according to the actual situation. The material of the supporting member 21 is a wear-resistant non-metallic material, which can reduce the risk of introducing metal molecules. For example, the material of the supporting member 21 can be polyetheretherketone, that is, PEEK material. Polyetheretherketone is a special engineering plastic with excellent high temperature resistance, chemical corrosion resistance and other characteristics. It is widely used in aerospace, medical equipment, automotive industry and other fields.

[0062] The first side 2121 is set to extend beyond the solid-state battery cell 200, which means that the amount by which the first side 2121 extends beyond the solid-state battery cell 200 may be any value such as 1mm, 2mm, 3mm, 4mm or 5mm, and the amount by which the first side 2121 extends beyond the solid-state battery cell 200 may be determined based on actual conditions.

[0063] In the technical solution of the embodiment of the present application, the aluminum-plastic film bag 300 is adopted as a bag structure with a bag opening 301 opened at one end. Through the setting of the positioning module 10, the positioning module 10 can position the aluminum-plastic film bag 300 and open the bag opening 301 of the aluminum-plastic film bag 300, so as to facilitate the solid-state battery monomer 200 to enter the aluminum-plastic film bag 300. Through the setting of the bag entry module 20, the supporting member 21 in the bag entry module 20 can move along the first direction X relative to the positioning module 10. After the solid-state battery monomer 200 is placed on the supporting member 21, the supporting member 21 is moved along the first direction X. The supporting member 21 can carry the solid-state battery monomer 200 from the bag opening 301 of the aluminum-plastic film bag 300 into the aluminum-plastic film bag 300, completing the bag entry process of the solid-state battery monomer 200, and the operation is convenient and fast. More importantly, the supporting member 21 includes a bottom plate 211 and two side plates 212, and the two side plates 212 are respectively arranged on both sides of the second direction Y of the bottom plate 211. When the solid-state battery cell 200 is placed on the bottom plate 211, the first side 2121 is arranged beyond the solid-state battery cell 200. In this way, when the supporting member 21 carries the solid-state battery cell 200 into the aluminum-plastic film bag 300, the side plates 212 can replace the solid-state battery cell 200 to contact the inner wall of the aluminum-plastic film bag 300. The side plates 212 can protect the solid-state battery cell 200. The solid-state battery cell 200 will not contact the inner wall of the aluminum-plastic film bag 300 and be scratched, which can effectively reduce the risk of the solid-state battery cell 200 being scratched by the aluminum-plastic film bag 300 when entering the bag, and correspondingly reduce the risk of the insulating glue around the solid-state battery cell 200 being damaged and causing the subsequent short circuit of the solid-state battery cell 200, thereby improving the reliability of the solid-state battery cell 200.

[0064] Furthermore, when the solid-state battery cell 200 is bagged, the solution directly uses a finished aluminum-plastic film bag 300 with one end open, and there is no need to punch holes in the aluminum-plastic film in advance, which can save the mold and process of punching holes in the aluminum-plastic film. Moreover, after the solid-state battery cell 200 is placed in the aluminum-plastic film bag 300 using the bagging module 20, it is not necessary to perform multiple top and side seals. After the bagging module 20 is separated from the solid-state battery cell 200, only one top or side seal is required, which optimizes the bagging and packaging process of the solid-state battery cell 200 and shortens the time required for packaging the solid-state battery cell 200.

[0065] According to some embodiments of the present application, when the solid-state battery cell 200 is placed on the bottom plate 211 , the first side 2121 protrudes from the solid-state battery cell 200 by no less than 2 mm.

[0066] The first side 2121 is arranged beyond the solid-state battery cell 200, which means that after the solid-state battery cell 200 is placed on the supporting member 21, the first side 2121 of the side plate 212 is arranged beyond the top surface of the solid-state battery cell 200. The first side 2121 is arranged beyond the solid-state battery cell 200 by not less than 2 mm, which means that the first side 2121 can be any value such as 2 mm, 3 mm, 4 mm or 5 mm beyond the solid-state battery cell 200, and the first side 2121 can be determined according to actual conditions.

[0067] The protrusion of the first side 2121 beyond the solid-state battery cell 200 is set to be not less than 2 mm. The first side 2121 of the side plate 212 can effectively protect the solid-state battery cell 200, reduce the risk of contact or even scratch between the solid-state battery cell 200 and the inner wall of the aluminum-plastic film bag 300, and improve the reliability and stability of the solid-state battery cell 200 entering the bag.

[0068] According to some embodiments of the present application, the side panel 212 is detachably connected to the bottom panel 211 .

[0069] There are many ways to detachably connect the side plate 212 and the bottom plate 211. The side plate 212 and the bottom plate 211 can be connected by means of clamping, screwing, etc. Taking the direct screw connection between the side plate 212 and the bottom plate 211 as an example, the first fastener is passed through the side plate 212 and threadedly matched with the screw hole on the bottom plate 211. Alternatively, the first fastener is passed through the bottom plate 211 and threadedly matched with the threaded hole on the side plate 212.

[0070] In some embodiments, the side plate 212 may be a telescopic plate structure so that the distance between the first side of the side plate 212 and the bottom plate 211 is adjustable, so that there is no need to replace different types of side plates 212. For example, the side plate 212 may include a first plate and a second plate, the first plate having an inner cavity for inserting the second plate, the second plate extending along the height direction of the side plate 212 with a limiting groove, the first plate having a locking member threadedly engaged, the locking member may be a locking screw, the locking member is threadedly engaged with the first plate, one end of the locking member is inserted into the inner cavity and abuts against the limiting groove of the second plate to limit the relative movement of the second plate and the first plate.

[0071] The side panels 212 and the bottom panel 211 are detachably connected, and the side panels 212 of different heights can be replaced according to the different models of the solid-state battery cells 200. This has a wider application range and can meet the bagging requirements of different models of solid-state battery cells 200.

[0072] According to some embodiments of this application, please refer to Figure 3 A negative pressure adsorption member 213 is provided on the bottom plate 211 , and the negative pressure adsorption member 213 is used to adsorb and position the solid-state battery cell 200 .

[0073] The negative pressure adsorption component 213 refers to an adsorption component that can provide negative pressure adsorption force. The negative pressure adsorption component 213 can provide negative pressure adsorption force on the supporting surface 214 of the bottom plate 211 to adsorb and position the solid-state battery cell 200, maintain the relative position of the solid-state battery cell 200 and the supporting component 21, and prevent the solid-state battery cell 200 from moving relative to the supporting component 21.

[0074] The negative pressure adsorption component 213 may include a plurality of third negative pressure adsorption holes, which are spaced apart on the bearing surface 214 of the supporting component 21. The supporting component 21 has a negative pressure cavity inside, and the plurality of third negative pressure adsorption holes are connected to the negative pressure cavity. The negative pressure cavity is connected to the negative pressure generator through a third pipeline.

[0075] A negative pressure adsorption component 213 is provided on the bottom plate 211. After the solid-state battery cell 200 is placed on the bottom plate 211, the negative pressure adsorption component 213 can adsorb and position the solid-state battery cell 200. In the process of the supporting component 21 carrying the solid-state battery cell 200 into the bag, the risk of relative movement between the solid-state battery cell 200 and the supporting component 21 can be further reduced, so that the solid-state battery cell 200 can be bagged more accurately.

[0076] According to some embodiments of this application, please refer to Figure 1 and Figure 2 The aluminum-plastic film bag 300 has a first wall 302 and a second wall 303 which are relatively distributed in the thickness direction; the positioning module 10 includes a frame 11, a first suction plate 12 and a second suction unit 13, the first suction plate 12 is arranged on the frame 11, and the first suction plate 12 has a first suction surface for suction positioning with the first wall 302; the second suction unit 13 is arranged on the frame 11, and the second suction unit 13 includes a second suction plate 131, and the second suction plate 131 has a second suction surface for suction positioning with the second wall 303; the second suction unit 13 and the first suction plate are distributed on the frame 11 at intervals along the third direction; wherein, at least one of the first suction plate 12 and the second suction plate 131 is movably arranged on the frame 11 along the vertical direction Z, so that the second suction plate 131 and the first suction plate 12 can approach or move away from each other, and the third direction, the first direction X and the second direction Y are perpendicular to each other.

[0077] At least one of the first suction plate 12 and the second suction plate 131 is movably disposed on the frame 11 along the vertical direction Z, which can be divided into multiple situations. The first suction plate 12 can be movably disposed on the frame 11 along the vertical direction Z, and the second suction plate 131 is immovable relative to the frame 11. Alternatively, the first suction plate 12 is immovable relative to the frame 11, and the second suction plate 131 is movably disposed on the frame 11 along the vertical direction Z. Alternatively, both the first suction plate 12 and the second suction plate 131 can be movably disposed on the frame 11 along the vertical direction Z, and the bag opening 301 of the aluminum-plastic film bag 300 can be opened by moving the first suction plate 12 and the second suction plate 131 away from each other.

[0078] The first suction plate 12 has a first suction surface for adsorbing and positioning with the first wall 302, which means that the first suction plate 12 is provided with a first negative pressure suction cup or a first negative pressure adsorption hole, and the first negative pressure suction cup or the first negative pressure adsorption hole is connected to the negative pressure generator through a first pipeline.

[0079] The second suction plate 131 has a second suction surface for adsorbing and positioning with the second wall 303, which means that a second negative pressure suction cup or a second negative pressure adsorption hole is provided on the second suction plate 131, and the second negative pressure suction cup or the second negative pressure adsorption hole is connected to the negative pressure generator through a second pipeline.

[0080] Of course, when a negative pressure adsorption component 213 is provided on the bottom plate 211, the third negative pressure adsorption hole on the bottom plate 211 can also be connected to the same negative pressure generator through the third pipeline, and the supporting component 21, the first suction plate 12 and the second suction plate 131 can be connected to the same negative pressure generator, and it is only necessary to control the on and off of the first pipeline, the second pipeline and the third pipeline.

[0081] The positioning module 10 is formed of a first suction plate 12 and a second suction plate 131. The first suction plate 12 and the second suction plate 131 can respectively adsorb the first wall 302 and the second wall 303 on both sides of the thickness direction of the aluminum-plastic film bag 300 to complete the adsorption positioning of the aluminum-plastic film bag 300. At least one of the first suction plate 12 and the second suction plate 131 is movably disposed on the frame 11 along the vertical direction Z, so that the first suction plate 12 and the second suction plate 131 move relative to each other, driving the first wall 302 and the second wall 303 of the aluminum-plastic film bag 300 to move away from each other, thereby opening the bag mouth 301 of the aluminum-plastic film bag 300. The structure is simple and the positioning stability of the aluminum-plastic film bag 300 is high.

[0082] According to some embodiments of this application, please continue to refer to Figure 1The bag-entering module 20 also includes a first movable seat 22 and a first linear drive assembly 23. The first movable seat 22 is slidably arranged on the frame 11 along the first direction X, and the supporting member 21 is connected to the first movable seat 22; the first linear drive assembly 23 is arranged on the frame 11, and the first linear drive assembly 23 is used to drive the first movable seat 22 to move along the first direction X.

[0083] The first linear drive assembly 23 may be a variety of linear drive mechanisms, such as a cylinder, a hydraulic cylinder, an electric push rod, a screw-nut pair mechanism, or a gear rack mechanism, etc. The specific structure of the first linear drive assembly 23 may be determined according to actual conditions.

[0084] Optionally, the first linear drive assembly 23 may be a screw-nut pair mechanism, and the first linear drive assembly 23 may include a first drive motor 231, a first screw 232, a first guide portion 234 and a first nut seat 233. The first drive motor 231 is mounted on the frame 11, and the first screw 232 is rotatably mounted on the frame 11. The first drive motor 231 is used to drive the first screw 232 to rotate, and the first guide portion 234 is extended along the first direction X on the frame 11. The first nut seat 233 is threadedly matched with the first screw 232, and the first nut seat 233 is slidably matched with the first guide portion 234, and the first guide portion 234 is extended along the first direction X. The first movable seat 22 is connected to the first nut seat 233.

[0085] Through the arrangement of the first linear drive component 23 and the first movable seat 22, the supporting member 21 is arranged on the first movable seat 22. The first linear drive component 23 can provide power to drive the first movable seat 22 to move along the first direction X, thereby driving the supporting member 21 to enter the aluminum-plastic film bag 300 from the bag opening 301 of the aluminum-plastic film bag 300 to complete the bagging of the solid-state battery monomer 200. There is no need to manually complete the movement of the supporting member 21 into the bag. The movement accuracy of the supporting member 21 is high, which reduces the workload of the staff and has a high degree of automation.

[0086] According to some embodiments of this application, please combine Figure 1 , Figure 6 and Figure 7 The bag-entering module 20 further includes a first flipping assembly 24, which is disposed between the first movable seat 22 and the supporting member 21, and is used to drive the supporting member 21 to flip; the second adsorption unit 13 further includes a second flipping assembly 132, which is disposed between the frame 11 and the second suction plate 131, and is used to drive the second suction plate 131 to flip, and the rotation axes of the supporting member 21 and the second suction plate 131 are collinear.

[0087] After the support member 21 places the solid-state battery cell 200 into the aluminum-plastic film bag 300, there are many ways to separate the support member 21 from the solid-state battery cell 200. For example, the side of the support member 21 away from the aluminum-plastic film bag 300 can be slightly tilted upward to make the support member 21 in an inclined state, and then the support member 21 is withdrawn. Under the action of gravity, the solid-state battery cell 200 will not move with the support member 21, and the support member 21 and the solid-state battery cell 200 can be separated. Alternatively, the support member 21 and the second suction plate 131 are turned over 180 degrees together. In this way, after the bearing surface 214 of the support member 21 is turned over, under the action of gravity, the gravity of the aluminum-plastic film bag 300 and the solid-state battery cell 200 in the bag falls on the second suction plate 131, and the support member 21 can be easily pulled out of the aluminum-plastic film bag 300.

[0088] The first flip assembly 24 and the second flip assembly 132 may have the same structure. The first flip assembly 24 may include a first flip motor 241 and a first rotating arm 242. The first flip motor 241 is mounted on the first moving seat 22. The driving end of the first flip motor 241 is connected to the first rotating arm 242. The supporting member 21 is connected to the first rotating arm 242. The second flip assembly 132 may include a second flip motor 1321 and a second rotating arm 1322. The second flip motor 1321 is mounted on the frame 11. The driving end of the second flip motor 1321 is connected to the second rotating arm 1322. The second suction plate 131 is connected to the second rotating arm 1322.

[0089] Before the first flip assembly 24 and the second flip assembly 132 drive the supporting member 21 and the second suction plate 131 to flip, the first suction plate 12 may be allowed to give way or the second suction plate 131 and the supporting member 21 may be moved in advance to form a flipping space for the first flip assembly 24 and the second flip assembly 132. The first method is to allow the first suction plate 12 to move downward in the vertical direction Z to reserve a flipping space for the second suction plate 131 and the supporting member 21. The second method is to allow the first suction plate 12 to remain stationary and allow the second suction plate 131 and the supporting member 21 to move upward in the vertical direction Z to form a flipping space for the second suction plate 131 and the supporting member 21. The method for the first suction plate 12 to give way may be determined according to actual conditions.

[0090] Through the arrangement of the first flip assembly 24 and the second flip assembly 132, after the support member 21 puts the solid-state battery monomer 200 into the aluminum-plastic film bag 300, the first suction plate 12 can be allowed to give way or the second suction plate 131 can be allowed to rise synchronously with the support member 21 to form a flipping space after the first suction plate 12 gives way, and then the first flip assembly 24 and the second flip assembly 132 are turned over at the same time to flip the support member 21 and the second suction plate 131 together by 180 degrees, so that the aluminum-plastic film bag 300 The gravity of the solid-state battery cell 200 in the aluminum-plastic film bag 300 falls on the second suction plate 131. During the process of pulling the supporting member 21 out of the aluminum-plastic film bag 300, the supporting member 21 is not easy to contact with the solid-state battery cell 200, and the solid-state battery cell 200 will not be displaced due to the movement of the supporting member 21 during the pulling out process, thereby ensuring that the position of the solid-state battery cell 200 in the aluminum-plastic film bag 300 will not change, and the supporting member 21 can be pulled out of the aluminum-plastic film bag 300 relatively easily.

[0091] According to some embodiments of this application, please refer to Figure 1 The first suction plate 12 is fixedly disposed on the frame 11 ; the second suction plate 131 and the supporting member 21 are movably disposed on the frame 11 along the vertical direction Z to approach or move away from the first suction plate 12 .

[0092] The first suction plate 12 is fixedly arranged on the frame 11, which means that the position of the first suction plate 12 on the frame 11 does not change. The first suction plate 12 mainly supports the aluminum-plastic film bag 300 when the solid-state battery monomer 200 is bagged and cooperates with the second suction plate 131 to open the bag mouth 301 of the aluminum-plastic film bag 300. The second suction plate 131 and the supporting member 21 are movably arranged on the frame 11 along the vertical direction Z to approach or move away from the first suction plate 12, which means that the supporting member 21 and the second suction plate 131 can be lifted and lowered in the vertical direction Z, so as to approach or move away from the first suction plate 12.

[0093] By fixing the first suction plate 12 on the frame 11, the second suction plate 131 and the supporting member 21 are movably arranged on the frame 11 along the vertical direction Z to be close to or away from the first suction plate 12, so that when the bag opening 301 of the aluminum-plastic film bag 300 is opened, it is only necessary to move the second suction plate 131 relative to the first suction plate 12 in a direction away from the first suction plate 12 to open the bag opening 301 of the aluminum-plastic film bag 300. When the supporting member 21 is withdrawn from the aluminum-plastic film bag 300, the second suction plate 131 and the supporting member 21 can be turned over synchronously, so that the supporting member 21 is turned over to the upper side of the solid-state battery cell 200, and the second suction plate 131 provides a supporting effect for the aluminum-plastic bag film, which facilitates the separation of the supporting member 21 from the aluminum-plastic film bag 300.

[0094] According to some embodiments of the present application, the second adsorption unit 13 includes a second linear drive component 133 and a second movable seat 134, and the second linear drive component 133 is arranged on the frame 11; the second movable seat 134 is connected to the second linear drive component 133, and the second flipping component 132 is arranged between the second movable seat 134 and the second suction plate 131, and the second linear drive component 133 is used to drive the second suction plate 131 to move along the vertical direction Z to approach or move away from the first suction plate 12.

[0095] The second linear drive assembly 133 can be a variety of linear drive mechanisms, and the second linear drive assembly 133 can be a cylinder, a hydraulic cylinder, an electric push rod, a screw nut pair mechanism or a gear rack mechanism. The specific structure of the second linear drive assembly 133 can be determined according to actual conditions. Optionally, the second linear drive assembly 133 may include a second cylinder 1331 and a second guide portion 1332, the second guide portion 1332 extends along the vertical direction Z and is arranged on the frame 11, the second movable seat 134 is slidably matched with the second guide portion 1332, and the second guide portion 1332 can guide the movement of the second movable seat 134.

[0096] By setting the second linear drive component 133 and the second movable seat 134, the second flip component 132 is set between the second movable seat 134 and the second suction plate 131. The second linear drive component 133 can provide power to drive the second movable seat 134 to move along the vertical direction Z, thereby driving the second suction plate 131 to approach or move away from the first suction plate 12. There is no need to manually complete the lifting and lowering action of the second suction plate 131, which reduces the workload of the staff, has a high degree of automation, and the movement accuracy of the second suction plate 131 is high.

[0097] According to some embodiments of the present application, the bag entering module 20 also includes a first lifting seat 25 and a third linear drive assembly 26, the first linear drive assembly 23 is arranged on the first lifting seat 25; the third linear drive assembly 26 is arranged on the frame 11, and the third linear drive assembly 26 is used to drive the first lifting seat 25 to move along the vertical direction Z relative to the frame 11.

[0098] The third linear drive assembly 26 can be a variety of linear drive mechanisms, and the third linear drive assembly 26 can be a cylinder, a hydraulic cylinder, an electric push rod, a screw nut pair mechanism, or a gear rack mechanism. The specific structure of the second linear drive assembly 133 can be determined according to actual conditions. Optionally, the third linear drive assembly 26 may include a third cylinder 261 and a third guide portion 262, the third guide portion 262 extends along the vertical direction Z and is arranged on the frame 11, the third cylinder 261 is arranged on the frame 11, the first lifting seat 25 is slidably matched with the third guide portion 262, and the first linear drive assembly 23 is arranged on the first lifting seat 25.

[0099] Through the arrangement of the third linear drive component 26 and the first lifting seat 25, the first linear drive component 23 is arranged on the first lifting seat 25, and the third linear drive component 26 can provide power to drive the first linear drive component 23 and the first movable seat 22 to move along the vertical direction Z, thereby driving the supporting member 21 to move along the vertical direction Z together with the second suction plate 131, providing a flipping space for the flipping of the supporting member 21 and the second suction plate 131, and there is no need for manual completion of the lifting action of the first lifting seat 25, thereby reducing the workload of the staff and having a high degree of automation.

[0100] The complete process of the bagging device 100 of the embodiment of the present application is described in detail below:

[0101] Please refer to Figure 1 , place the solid-state battery cell 200 on the supporting member 21, and the aluminum-plastic film bag 300 on the first suction plate 12, and move the second suction plate 131 relative to the first suction plate 12 in the vertical direction Z in advance. The first suction plate 12 and the second suction plate 131 cooperate to absorb the first wall 302 and the second wall 303 of the aluminum-plastic film bag 300, respectively, so that the bag opening 301 of the aluminum-plastic film bag 300 can be opened. Then the first linear drive component 23 drives the supporting member 21 to move along the first direction X. Under the action of the first linear drive component 23, the supporting member 21 enters from the bag opening 301 of the aluminum-plastic film bag 300 until the solid-state battery cell 200 is completely located in the aluminum-plastic film bag 300, as shown in FIG. Figure 5 As shown, Figure 5 The dotted line in the figure indicates the support member 21 and the solid-state battery cell 200 located in the aluminum-plastic film bag 300. Then, the adsorption force of the first suction plate 12 is stopped. Figure 6 Under the driving action of the second linear drive assembly 133 and the third linear drive assembly 26, the second suction plate 131 and the supporting member 21 are driven to drive the aluminum-plastic film bag 300 to move upward synchronously, away from the first suction plate 12, so as to form a space for the second suction plate 131 and the supporting member 21 to turn over. Figure 7 Then the first flip assembly 24 and the second flip assembly 132 are flipped 180° synchronously, and the gravity of the aluminum-plastic film bag 300 and the solid-state battery cell 200 falls on the second suction plate 131, and the second suction plate 131 continues to absorb and position the aluminum-plastic film bag 300. Then the support member 21 is moved slightly upward to separate from the solid-state battery cell 200, so that a gap is formed between the support member 21 and the solid-state battery cell 200. Please refer to Figure 8 Then the first linear drive assembly 23 drives the supporting member 21 to move along the first direction X to withdraw the aluminum film bag, and the second suction plate 131 sucks the aluminum-plastic film bag 300 and supports the solid-state battery cell 200 to complete the positioning of the solid-state battery cell 200 into the bag.

[0102] An embodiment of the present application further provides a battery manufacturing device, the battery manufacturing device comprising the bagging device 100 of any of the aforementioned embodiments.

[0103] The embodiment of the present application also provides a bagging method, which is based on the bagging device 100 of any of the aforementioned embodiments, and the bagging method includes: placing the solid-state battery cell 200 on the supporting member 21; opening the bag opening 301 of the aluminum-plastic film bag 300, allowing the supporting member 21 to move along the first direction X, and the supporting member 21 carries the solid-state battery cell 200 from the bag opening 301 of the aluminum-plastic film bag 300 into the aluminum-plastic film bag 300; turning the supporting member 21 and the aluminum-plastic film bag 300 together by 180°, and withdrawing the supporting member 21 from the aluminum-plastic film bag 300.

[0104] After the positioning module 10 opens the bag opening 301 of the aluminum-plastic film bag 300, the supporting member 21 moves along the first direction X, and the supporting member 21 carries the solid-state battery cell 200 into the aluminum-plastic film bag 300 from the bag opening 301 of the aluminum-plastic film bag 300. The side plate 212 of the supporting member 21 can protect the solid-state battery cell 200 and reduce the risk of scratches between the solid-state battery cell 200 and the inner wall of the aluminum-plastic film bag 300. By flipping the supporting member 21 and the aluminum-plastic film bag 300 by 180°, the supporting member 21 is located on the upper side of the solid-state battery cell 200, which is conducive to withdrawing the supporting member 21 from the aluminum-plastic film bag 300.

[0105] According to some embodiments of the present application, the supporting member 21 is withdrawn from the aluminum-plastic film bag 300, including moving the supporting member 21 and the solid-state battery cell 200 relative to each other in a third direction so that a gap is formed between the supporting member 21 and the solid-state battery cell 200 in the third direction, and then withdrawing the supporting member 21 from the aluminum-plastic film bag 300.

[0106] When the supporting member 21 is withdrawn from the aluminum-plastic film bag 300, although the supporting member 21 is located on the upper side of the solid-state battery cell 200 after being turned 180°, in order to further reduce the risk of relative friction with the solid-state battery cell 200 or displacement of the solid-state battery cell 200 when the supporting member 21 is withdrawn from the aluminum-plastic film bag 300 along the first direction X, the supporting member 21 and the solid-state battery cell 200 can be relatively moved in the third direction, so that a gap is formed between the supporting member 21 and the solid-state battery cell 200 in the third direction, so that the supporting member 21 will not contact the solid-state battery cell 200 during the process of pulling the supporting member 21 out of the aluminum-plastic film bag 300.

[0107] In some embodiments, please refer to Figures 1 to 8The bagging device 100 is used to place the solid-state battery cell 200 into the aluminum-plastic film bag 300. One end of the aluminum-plastic film bag 300 in the first direction X has an open bag mouth 301. The bagging device 100 includes a positioning module 10 and a bagging module 20. The positioning module 10 is used to position the aluminum-plastic film bag 300 and open the bag mouth 301 of the aluminum-plastic film bag 300. The bagging module 20 includes a supporting member 21 for carrying the solid-state battery cell 200. The supporting member 21 is movably arranged on the positioning module 10 along the first direction X to place the solid-state battery cell 200. The body 200 is placed in the aluminum-plastic film bag 300 from the bag opening 301; wherein, the supporting member 21 includes a bottom plate 211 and two side plates 212, the bottom plate 211 has a bearing surface 214 for bearing the solid-state battery cell 200, the two side plates 212 are respectively arranged on opposite sides of the second direction Y of the bearing surface 214, and the side plate 212 has a first side 2121 away from the bearing surface 214; when the solid-state battery cell 200 is placed on the bottom plate 211, the first side is arranged beyond the solid-state battery cell 200, and the first direction X is perpendicular to the second direction Y. When the solid-state battery cell 200 is placed on the bottom plate 211, the first side 2121 exceeds the solid-state battery cell 200 by not less than 2 mm. A negative pressure adsorption member 213 is arranged on the bottom plate 211, and the negative pressure adsorption member 213 is used to adsorb and position the solid-state battery cell 200.

[0108] The aluminum-plastic film bag 300 is a bag structure with an open end and a bag opening 301. Through the setting of the positioning module 10, the positioning module 10 can position the aluminum-plastic film bag 300 and open the bag opening 301 of the aluminum-plastic film bag 300, so as to facilitate the solid-state battery monomer 200 to enter the aluminum-plastic film bag 300. Through the setting of the bag entry module 20, the supporting member 21 in the bag entry module 20 can move along the first direction X relative to the positioning module 10. After the solid-state battery monomer 200 is placed on the supporting member 21, the supporting member 21 is moved along the first direction X. The supporting member 21 can carry the solid-state battery monomer 200 from the bag opening 301 of the aluminum-plastic film bag 300 into the aluminum-plastic film bag 300, completing the bag entry process of the solid-state battery monomer 200, and the operation is convenient and fast. More importantly, the supporting member 21 includes a bottom plate 211 and two side plates 212, and the two side plates 212 are respectively arranged on both sides of the second direction Y of the bottom plate 211. When the solid-state battery cell 200 is placed on the bottom plate 211, the first side 2121 is arranged beyond the solid-state battery cell 200. In this way, when the supporting member 21 carries the solid-state battery cell 200 into the aluminum-plastic film bag 300, the side plates 212 can replace the solid-state battery cell 200 to contact the inner wall of the aluminum-plastic film bag 300. The side plates 212 can protect the solid-state battery cell 200. The solid-state battery cell 200 will not contact the inner wall of the aluminum-plastic film bag 300 and be scratched, which can effectively reduce the risk of the solid-state battery cell 200 being scratched by the aluminum-plastic film bag 300 when entering the bag, and correspondingly reduce the risk of the insulating glue around the solid-state battery cell 200 being damaged and causing the subsequent short circuit of the solid-state battery cell 200, thereby improving the reliability of the solid-state battery cell 200. The amount of the first side exceeding the solid-state battery cell 200 is set to be no less than 2 mm. The first side 2121 of the side plate 212 can effectively protect the solid-state battery cell 200, reduce the risk of the solid-state battery cell 200 contacting or even scratching the inner wall of the aluminum-plastic film bag 300, and improve the reliability and stability of the solid-state battery cell 200 entering the bag. The negative pressure adsorption member 213 can adsorb and position the solid-state battery cell 200. In the process of the support member 21 carrying the solid-state battery cell 200 into the bag, the risk of relative movement between the solid-state battery cell 200 and the support member 21 can be further reduced, so that the solid-state battery cell 200 can be entered into the bag more accurately.

[0109] In some embodiments, the aluminum-plastic film bag 300 has a first wall 302 and a second wall 303 relatively distributed in the thickness direction; the positioning module 10 includes a frame 11, a first suction plate 12 and a second suction unit 13, the first suction plate 12 is arranged on the frame 11, and the first suction plate 12 has a first suction surface for suction positioning with the first wall 302; the second suction unit 13 is arranged on the frame 11, and the second suction unit 13 includes a second suction plate 131, and the second suction plate 131 has a second suction surface for suction positioning with the second wall 303; the second suction unit 13 and the first suction plate are distributed on the frame 11 at intervals along the third direction; wherein, at least one of the first suction plate 12 and the second suction plate 131 is movably arranged on the frame 11 along the vertical direction Z, so that the second suction plate 131 and the first suction plate 12 can approach or move away from each other, and the third direction, the first direction X and the second direction Y are perpendicular to each other. The bagging module 20 further includes a first movable seat 22 and a first linear drive assembly 23. The first movable seat 22 is slidably disposed on the frame 11 along the first direction X, and the supporting member 21 is connected to the first movable seat 22. The first linear drive assembly 23 is disposed on the frame 11, and the first linear drive assembly 23 is used to drive the first movable seat 22 to move along the first direction X. The bagging module 20 further includes a first flip assembly 24, which is disposed between the first movable seat 22 and the supporting member 21, and the first flip assembly 24 is used to drive the supporting member 21 to flip. The second adsorption unit 13 further includes a second flip assembly 132, which is disposed between the frame 11 and the second suction plate 131, and the second flip assembly 132 is used to drive the second suction plate 131 to flip, and the rotation axes of the supporting member 21 and the second suction plate 131 are collinear. The first suction plate 12 is fixedly disposed on the frame 11 ; the second suction plate 131 and the supporting member 21 are movably disposed on the frame 11 along the vertical direction Z to be close to or away from the first suction plate 12 .

[0110] The positioning module 10 is formed of a first suction plate 12 and a second suction plate 131. The first suction plate 12 and the second suction plate 131 can respectively adsorb the first wall 302 and the second wall 303 on both sides of the thickness direction of the aluminum-plastic film bag 300 to complete the adsorption positioning of the aluminum-plastic film bag 300. At least one of the first suction plate 12 and the second suction plate 131 is movably disposed on the frame 11 along the vertical direction Z, so that the first suction plate 12 and the second suction plate 131 move relative to each other, driving the first wall 302 and the second wall 303 of the aluminum-plastic film bag 300 to move away from each other, thereby opening the bag mouth 301 of the aluminum-plastic film bag 300. The structure is simple and the positioning stability of the aluminum-plastic film bag 300 is high. Through the arrangement of the first linear drive component 23 and the first movable seat 22, the supporting member 21 is arranged on the first movable seat 22. The first linear drive component 23 can provide power to drive the first movable seat 22 to move along the first direction X, thereby driving the supporting member 21 to enter the aluminum-plastic film bag 300 from the bag opening 301 of the aluminum-plastic film bag 300 to complete the bagging of the solid-state battery monomer 200. There is no need to manually complete the movement of the supporting member 21 into the bag. The movement accuracy of the supporting member 21 is high, which reduces the workload of the staff and has a high degree of automation. By means of the first flip assembly 24 and the second flip assembly 132, after the supporting member 21 delivers the solid-state battery cell 200 into the aluminum-plastic film bag 300, the first suction plate 12 does not move, and the second suction plate 131 and the supporting member 21 are synchronously raised to form a flipping space after the first suction plate 12 gives way. Then, the first flip assembly 24 and the second flip assembly 132 are flipped at the same time to flip the supporting member 21 and the second suction plate 131 together by 180°, so that the gravity of the aluminum-plastic film bag 300 and the solid-state battery cell 200 in the aluminum-plastic film bag 300 falls on the second suction plate 131. In the process of withdrawing the supporting member 21 from the aluminum-plastic film bag 300, the supporting member 21 is not easy to contact the solid-state battery cell 200, and the solid-state battery cell 200 will not be displaced due to the movement of the supporting member 21 during the withdrawal process, thereby ensuring that the position of the solid-state battery cell 200 in the aluminum-plastic film bag 300 will not change, and the supporting member 21 can be easily withdrawn from the aluminum-plastic film bag 300.
