[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure is based on the Chinese patent application with application number 202410123259.9, application date January 30, 2024, and invention name “Gluing system, glueing method and battery production line”, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into the present disclosure as a reference. Technical Field

[0003] The present disclosure relates to the field of battery technology, and in particular to a gluing system, a gluing method and a battery production line. Background Art

[0004] New energy batteries are being used more and more widely in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are also being increasingly used in energy storage fields.

[0005] During the production process, battery cells require welding at the tabs, primarily using metal ultrasonic welding. After ultrasonic welding, the tabs need to be glued. However, traditional glue application and preparation mechanisms often suffer from slow glue application cycles.

[0006] Summary of the Invention

[0007] In view of this, the embodiments of the present disclosure hope to provide a gluing system, a gluing method and a battery production line, aiming to speed up the gluing cycle of the gluing system.

[0008] To achieve the above objectives, the technical solution of the embodiment of the present disclosure is implemented as follows:

[0009] The present disclosure provides a glue laminating system having auxiliary stations for loading and unloading materials. The glue laminating system includes:

[0010] A glue applying component having glue applying positions for applying glue, the number of the glue applying components being at least two, the glue applying positions of the plurality of glue applying components being arranged in a first direction, the auxiliary station being provided between at least two adjacent glue applying components, the glue applying position of one of the glue applying components corresponding to the two adjacent glue applying components being the first glue applying position, and the glue applying position of the other glue applying component being the second glue applying position;

[0011] A transverse movement mechanism has two accommodating areas arranged along the first direction, and the accommodating areas are used to place bare batteries to be glued. The transverse movement mechanism moves along the first direction to drive one of the accommodating areas to switch between the first gluing position and the auxiliary station, and to drive the other accommodating area to switch between the second gluing position and the auxiliary station.

[0012] In the embodiment of the present disclosure, both accommodating areas can move along the first direction following the transverse movement mechanism, and one of the accommodating areas can be moved to the corresponding gluing position, and the other accommodating area can be moved to the auxiliary workstation. The gluing time of the bare battery cells in the accommodating area located at the corresponding gluing position can be fully utilized, and the bare battery cells in the accommodating area located at the auxiliary workstation can be loaded or unloaded, thereby reducing the time for the bare battery cells to wait for gluing, which is conducive to speeding up the gluing rhythm of the gluing system.

[0013] In one embodiment, one of the two accommodating areas is stationary relative to the other accommodating area. When one of the accommodating areas is located at the corresponding gluing position, the other accommodating area is located at the auxiliary work station.

[0014] In the embodiment of the present disclosure, one accommodating area can move synchronously with another accommodating area. When the pairs of bare battery cells in one accommodating area are moved to the corresponding gluing positions for gluing, the other accommodating area can also be moved synchronously to the auxiliary workstation for loading or unloading, further reducing the time for the bare battery cells to wait for gluing, which is conducive to speeding up the gluing rhythm of the gluing system.

[0015] In one embodiment, the gluing system further includes a detection component, which is located between the first gluing position and the second gluing position along the first direction, and the detection component is used to detect the bare battery cell located in the accommodating area of ​​the auxiliary workstation.

[0016] In the disclosed embodiment, after loading into the receiving area at the auxiliary station, the inspection component can inspect the paired bare cells and reject any unqualified bare cells. After the bare cells pass the inspection, they are then glued, avoiding wasting glue time and glue resources, and improving glue application efficiency.

[0017] In one embodiment, the detection component has a detection part, the transverse movement mechanism has an avoidance hole connected to the corresponding accommodating area, the detection part is located below the avoidance hole, the projection area of ​​the avoidance hole corresponding to the accommodating area located at the auxiliary workstation along the up and down directions is the first area, the projection area of ​​the detection part along the up and down directions is the second area, and the second area is located within the first area, so that the detection part can detect the welding status of the adapter through the avoidance hole corresponding to the accommodating area located at the auxiliary workstation.

[0018] In the disclosed embodiment, since the adapter sheet is located below the bare cell tab and is thicker than the bare cell tab, if the thicker adapter sheet can penetrate the thinner tab, the welding quality between the adapter sheet and the tab can be determined to be acceptable. Therefore, the detection unit only needs to be located below the avoidance hole and be able to detect the welding status below the adapter sheet through the avoidance hole to determine whether the bare cell welding quality is acceptable. There is no need to set the detection unit above the adapter sheet, which is beneficial to improving detection efficiency and saving internal space of the glue application system.

[0019] In one embodiment, the glue application component has a first glue preparation position and a second glue preparation position, the first glue preparation position and the second glue preparation position are respectively used to obtain glue with different directions on the bonding side, the arrangement direction of the first glue preparation position and the second glue preparation position is the second direction, and the glue application position is located between the corresponding first glue preparation position and the corresponding second glue preparation position along the second direction.

[0020] In the embodiment of the present disclosure, when the paired bare cells are glued in the accommodating area of ​​the glue-sticking position, the first glue-sticking position and the second glue-sticking position corresponding to the accommodating area of ​​the auxiliary workstation can obtain glue with different bonding side directions, thereby making full use of the glue-sticking time of the bare cells in the accommodating area of ​​the glue-sticking position, which is conducive to speeding up the glue-sticking rhythm of the glue-sticking system.

[0021] In one embodiment, there are two gluing assemblies, which are arranged opposite to each other, and the auxiliary workstation and the one transverse movement mechanism are both located between the two gluing assemblies.

[0022] In the embodiment of the present disclosure, a transverse movement mechanism is provided in the two gluing components, wherein one accommodating area is located at the gluing position for gluing, the other accommodating area is located at the auxiliary station for loading and unloading, and the first and second gluing preparation positions corresponding to the accommodating area located at the auxiliary station for gluing do not interfere with each other, so that the loading or unloading of the accommodating area located at the auxiliary station and the gluing of the first and second gluing preparation positions corresponding to the accommodating area located at the auxiliary station make full use of the gluing time of the pairs of bare cells in the accommodating area located at the gluing position, which is beneficial to speed up the gluing rhythm of the gluing system.

[0023] In one embodiment, the glue assembly includes a glue device, which includes a first glue part, a second glue part, a guide shaft and an elastic part. One of the first glue part and the second glue part is connected to the guide shaft, and the other of the first glue part and the second glue part is movably arranged on the guide shaft. The elastic part is sleeved on the guide shaft, and the elastic part is in contact with the first glue part and the second glue part respectively.

[0024] In the embodiment of the present disclosure, one end of the guide shaft is connected to the lower bottom surface of the top of the second adhesive member, and the other end is connected to the upper top surface of the first adhesive member. The elastic member is sleeved on the guide shaft, so that the first adhesive member can move along the axial direction of the guide shaft, so that the colloid can be completely and densely adhered to the tab and the side of the bare battery cell close to the tab.

[0025] In one embodiment, the first adhesive member has a first limiting portion and a first adhesive pressing surface for adhesive pressing, and the second adhesive member has a second limiting portion and a second adhesive pressing surface for adhesive pressing. The first limiting portion is used to abut against the second limiting portion to limit the movement of the first adhesive member and the second adhesive member under the elastic force of the elastic member. When the first limiting portion and the second limiting portion abut against each other, the first adhesive pressing surface and the second adhesive pressing surface are flush.

[0026] In the disclosed embodiment, the first glue pressing surface and the second glue pressing surface are flush, so that the glue can be evenly adsorbed on the glue applying device, which helps to reduce the difficulty of the glue applying device in sucking glue at the corresponding glue preparation position.

[0027] The present disclosure also provides a method for applying glue, including:

[0028] One of the accommodating areas is driven by a transverse movement mechanism to move from an auxiliary station between two glue-applying components to a glue-applying position of one of the glue-applying components along a first direction, wherein the first direction is an arrangement direction of the glue-applying positions of the plurality of glue-applying components;

[0029] Gluing the bare battery cells located in the accommodation area corresponding to the gluing position by the gluing assembly;

[0030] Before the bare battery cell located in the storage area corresponding to the gluing position completes gluing, another storage area can reach the auxiliary station from the gluing position of another gluing component, so that the bare battery cell can be loaded to the storage area corresponding to the auxiliary station or unloaded from the storage area corresponding to the auxiliary station, and the two storage areas of the transverse movement mechanism are arranged along the first direction.

[0031] In the embodiment of the present disclosure, two accommodating areas are used to switch between the gluing position and the auxiliary station. When one of the accommodating areas is located at the corresponding gluing position and the other accommodating area is located at the auxiliary station, the gluing time of the bare battery cells in the accommodating area at the corresponding gluing position can be fully utilized, and the bare battery cells in the accommodating area at the auxiliary station can be loaded or unloaded, which is conducive to speeding up the gluing rhythm of the gluing assembly.

[0032] In one embodiment, the adhesive application assembly includes an adhesive application device, and the adhesive application method further includes:

[0033] When one of the accommodating areas is located at the corresponding gluing position, the gluing device of the gluing assembly corresponding to the other accommodating area is prepared for gluing.

[0034] In the disclosed embodiment, the transverse movement mechanism moves one of the storage areas to the corresponding gluing position, and the corresponding gluing device also moves to the corresponding gluing position. The other storage area is then moved to the auxiliary station, and the corresponding gluing device is then moved to the corresponding preparation position for gluing. This allows the gluing system to fully utilize the time it takes to glue one pair of bare cells to prepare the glue for another pair of bare cells, which helps speed up the gluing process.

[0035] In one embodiment, the adapter corresponding to the bare battery cell in the accommodation area is detected by a detection component, and the adhesive application method further includes:

[0036] When one of the accommodating areas is located at the corresponding gluing position, the detection component is used to detect the adapter corresponding to the bare battery cell in the accommodating area located at the auxiliary station.

[0037] In the disclosed embodiment, the traverse mechanism moves one of the storage areas to the corresponding gluing position, and the corresponding gluing device also moves to the corresponding gluing position. The other storage area is then moved to the auxiliary station, where the inspection component inspects the bare battery cells in the storage area at the auxiliary station. Once the cells pass the inspection, the corresponding gluing device prepares the glue at the corresponding preparation position, thus avoiding wasting glue resources and gluing time.

[0038] In one embodiment, the detection assembly has a detection portion, and the transverse movement mechanism has an avoidance hole;

[0039] When one of the accommodating areas is located at the corresponding gluing position, the detection component detects the adapter corresponding to the bare battery cell in the accommodating area located at the auxiliary station, including:

[0040] When one of the accommodating areas is located at the corresponding gluing position, the detection unit is used to detect the welding status of the adapter sheet located in the accommodating area of ​​the auxiliary station through the avoidance hole.

[0041] Place the paired bare cells in the accommodation area located in the auxiliary workstation, and the inspection department will inspect the welds of the adapter through the avoidance holes, and then determine whether to reject the paired bare cells based on the quality of the welds of the adapter.

[0042] The present disclosure also provides a battery production line, including:

[0043] The adhesive application system according to any one of the preceding embodiments;

[0044] The loading mechanism is used to place the welded bare cells and adapters into the receiving area at the auxiliary station;

[0045] The unloading mechanism is used to move the bare battery cell and the adapter sheet that have been glued out from the accommodating area at the auxiliary station.

[0046] In the embodiment of the present disclosure, the loading mechanism is used to place the welded pairs of bare cells into the accommodation area at the auxiliary workstation, and the unloading mechanism is used to move the pairs of bare cells that have completed gluing out of the accommodation area at the auxiliary workstation, which is beneficial to improving the production efficiency of the battery.

[0047] Effects of the Invention

[0048] In the gluing system provided by the embodiment of the present disclosure, both of the two accommodating areas of the transverse movement mechanism can move back and forth along the first direction. When one of the accommodating areas moves to the corresponding gluing position, the other accommodating area can be moved to the auxiliary work station, so that when the bare battery cell is being glued, the gluing system can prepare for the other bare battery cell before gluing, which is conducive to speeding up the gluing rhythm of the gluing system.

[0057] The following embodiments of the technical solution of the present disclosure are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present disclosure and are therefore only examples and are not intended to limit the scope of protection of the present disclosure.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure belongs; the terms used herein are for the purpose of describing specific embodiments only and are not intended to limit this disclosure; the terms "including" and "having" of the embodiments of this disclosure and any variations thereof are intended to cover non-exclusive inclusions.

[0059] In the description of the embodiments of the present disclosure, technical terms such as "first," "second," and "third" are used solely to distinguish different objects and should not be understood to indicate or imply relative importance or to implicitly specify the quantity, specific order, or primary and secondary relationship of the technical features indicated. In the description of the embodiments of the present disclosure, "plurality" means more than two, unless otherwise specifically defined.

[0060] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0061] In the description of the embodiments of the present disclosure, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0062] In the description of the embodiments of the present disclosure, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal connectivity between two components or interaction between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present disclosure based on specific circumstances.

[0063] In the description of the embodiments of the present disclosure, unless otherwise clearly specified and limited, the technical term "contact" should be understood in a broad sense, and can be direct contact, contact through an intermediate medium layer, contact with essentially no interaction force between the two contacting parties, or contact with interaction force between the two contacting parties.

[0064] As part of the creative concept of the present disclosure, before describing the embodiments of the present disclosure, it is necessary to analyze the reasons why the gluing rhythm of the gluing system in the related art is slow, and obtain the technical solution of the embodiments of the present disclosure through reasonable analysis.

[0065] The gluing process for bare cells is divided into loading, preparation, gluing, and unloading. In the related art, the gluing process of traditional gluing and preparation mechanisms is generally performed in a sequence where the next welded pair of bare cells can be loaded and glued only after the glue application is completed and unloaded. This results in a long waiting time for the next welded pair of bare cells to be glued, and a slow gluing cycle.

[0066] Exemplarily, the bare cells in pairs after welding are placed in the gluing system. The gluing system starts gluing after the glue is prepared. After the glued bare cells are removed, the next pair of bare cells with glue after welding are placed in the gluing system.

[0067] If the gluing time of the previous bare cell can be fully utilized to load and prepare the glue for the next bare cell to be glued in advance, the gluing cycle of the gluing system can be effectively accelerated. Therefore, the gluing system of the disclosed embodiment moves between the first gluing station, the second gluing station, and the auxiliary station via a transverse movement mechanism, so that the bare cells that have been welded are glued at the corresponding gluing stations, and the other bare cell to be glued can also be loaded and prepared at the auxiliary station. The above three actions do not affect each other, effectively utilizing the gluing time of the previous bare cell, which is conducive to accelerating the gluing cycle of the gluing system.

[0068] The solution of the disclosed embodiments can be applied to, but is not limited to, paired bare cells, battery cells, battery modules including battery cells, or battery packs including battery cells or battery modules after welding. By moving the transverse mechanism between the first gluing station, the second gluing station, and the auxiliary station, the paired bare cells after welding can be glued at the corresponding gluing station, while the other bare cell to be glued can also be loaded and prepared for glue at the auxiliary station, effectively speeding up the gluing cycle of the gluing system and improving the gluing efficiency of the battery cells in the corresponding battery pack.

[0069] The battery pack of the embodiment of the present disclosure may include a box body and battery cells, wherein the battery cells are located in the box body.

[0070] The box body refers to a structure with a receiving space, and the battery cells are located in the box body, and the box body receives the battery cells of the battery pack.

[0071] The number of battery cells can be multiple, and the multiple battery cells can be connected in series, in parallel, or in a mixed connection. Mixed connection means that the multiple battery cells are connected both in series and in parallel. The multiple battery cells can be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells is placed in a box. Of course, the multiple battery cells can first be connected in series, in parallel, or in a mixed connection to form a battery module, and the multiple battery modules can then be connected in series, in parallel, or in a mixed connection to form a whole, and the whole formed by the multiple battery modules connected in series, in parallel, or in a mixed connection can be placed in a box. The battery pack can also include other structures. For example, the battery pack can also include a busbar component for achieving electrical connection between the multiple battery cells.

[0072] A battery cell is a unit that can convert chemical energy into electrical energy.

[0073] In the embodiment of the present disclosure, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0074] In the embodiments of the present disclosure, the battery cells may be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc., but the embodiments of the present disclosure are not limited to this.

[0075] A battery cell consists of a housing, a terminal, an adapter, and a bare cell. The bare cell, welded to the adapter, is located within the housing, and the adapter is electrically connected to the terminal. Before the bare cell is placed in the housing, it is welded to the adapter. The welded bare cell and adapter are then bonded together with a colloid, ensuring a secure connection between the bare cell's tab and the adapter.

[0076] A bare cell includes positive and negative electrodes and a separator. The outer casing can be either sealed or unsealed. For example, the outer casing is unsealed, protecting the bare cell. The battery cell also includes a sealing bag, located between the outer casing and the bare cell, to encapsulate the bare cell. Specifically, the sealing bag can be a bag-shaped insulating member or an aluminum-plastic film.

[0077] In view of this, please refer to Figures 1, 3 and 4. An embodiment of the present disclosure provides a gluing system 1 having an auxiliary station 1a for loading and unloading, and the gluing system 1 includes a gluing component 11 and a transverse movement mechanism 12. The gluing component 11 has a gluing position for gluing, and the number of the gluing components 11 is at least two. The gluing positions of the multiple gluing components 11 are arranged in a first direction. An auxiliary station 1a is provided between at least two adjacent gluing components 11. Among the two adjacent gluing components 11 corresponding to the auxiliary station 1a, the gluing position of one gluing component 11 is a first gluing position 11a1, and the gluing position of the other gluing component 11 is a second gluing position 11a2. The transverse movement mechanism 12 has two accommodating areas 12a arranged along the first direction. The accommodating areas 12a are used to place bare batteries 13 to be glued. The transverse movement mechanism 12 moves along the first direction to drive one of the accommodating areas 12a to switch between the first gluing position 11a1 and the auxiliary station 1a, and to drive the other accommodating area 12a to switch between the second gluing position 11a2 and the auxiliary station 1a.

[0078] It should be noted that the direction indicated by R1 in FIG. 4 is the first direction.

[0079] The gluing assembly 11 refers to a structure in the gluing system 1 that performs gluing on the bare battery cell 13 , and can completely and densely adhere the glue to the portion of the bare battery cell 13 to be glued.

[0080] For example, referring to FIG. 1 , the number of the glue-applying components 11 may be two, and the two glue-applying components 11 correspond to one transverse movement mechanism 12 .

[0081] Exemplarily, the number of the adhesive assemblies 11 may be greater than two. For example, the number of the adhesive assemblies 11 may be three, four, or seven.

[0082] Exemplarily, the number of the gluing assemblies 11 may be greater than two, and each two adjacent gluing assemblies 11 are provided with an auxiliary station 1 a , and each two adjacent gluing assemblies 11 correspond to one transverse movement mechanism 12 .

[0083] The transverse movement mechanism 12 is the main structure for driving the accommodating area 12a to switch between the first gluing position 11a1, the second gluing position 11a2 and the auxiliary station 1a.

[0084] Exemplarily, the traverse mechanism 12 reciprocates along a first direction.

[0085] 6 , the bare cells 13 are welded bare cells 13 in pairs, with the two bare cells 13 arranged opposite each other near the tabs 131 and connected via a transfer sheet 132. For example, the bare cells 13 to be glued are bare cells 13 welded to the transfer sheet 132.

[0086] Exemplarily, the tabs 131 of the two bare battery cells 13 in a pair are welded to the adapter 132 .

[0087] Exemplarily, the bare cell 13 is glued, and the glue can be arranged across the bare cell 13 and the adapter 132 .

[0088] In the embodiment of the present disclosure, both accommodating areas 12a can move along the first direction following the transverse movement mechanism 12, and one of the accommodating areas 12a can be moved to the corresponding gluing position, and the other accommodating area 12a can be moved to the auxiliary workstation 1a. The gluing time of the bare battery cells 13 in the accommodating area 12a located at the corresponding gluing position can be fully utilized, and the bare battery cells 13 in the accommodating area 12a located at the auxiliary workstation 1a can be loaded or unloaded, thereby reducing the time for the bare battery cells 13 to wait for gluing, which is conducive to speeding up the gluing rhythm of the gluing system 1.

[0089] In one embodiment, referring to FIG. 1 , FIG. 3 and FIG. 4 , one of the two accommodating areas 12 a is stationary relative to the other accommodating area 12 a . When one of the accommodating areas 12 a is located at the corresponding gluing position, the other accommodating area 12 a is located at the auxiliary work station 1 a .

[0090] It should be explained that one of the accommodating areas 12 a is stationary relative to the other accommodating area 12 a , and one of the accommodating areas 12 a does not move relative to the other accommodating area 12 a .

[0091] For example, both receiving areas 12 a may be stationary, where one receiving area 12 a does not move relative to the other receiving area 12 a.

[0092] For example, when one of the accommodating areas 12 a moves, the other accommodating area 12 a moves along with it, and one of the accommodating areas 12 a does not move relative to the other accommodating area 12 a.

[0093] For example, a pair of bare cells 13 welded to the adapter sheet 132 is placed in the receiving area 12a of the auxiliary station 1a to load the receiving area 12a. After loading, the receiving area 12a of the auxiliary station 1a follows the transverse movement mechanism 12 and moves along the first direction to the first gluing position 11a1. The receiving area 12a of the second gluing position 11a2 also follows the receiving area 12a moving from the auxiliary station 1a to the first gluing position 11a1 and moves to the auxiliary station 1a. Another pair of bare cells 13 is placed in the receiving area 12a to utilize the gluing time of the pair of bare cells 13 in the receiving area 12a of the first gluing position 11a1 to load the receiving area 12a of the auxiliary station 1a again.

[0094] The gluing assembly 11 completes the gluing action on the paired bare cells 13 in the accommodating area 12a of the first gluing position 11a1, and also reloads the accommodating area 12a of the auxiliary station 1a. Then, the two accommodating areas 12a synchronously follow the transverse movement mechanism 12 to move along the first direction again. The accommodating area 12a at the auxiliary station 1a follows the transverse movement mechanism 12 to move to the second gluing position 11a2. The accommodating area 12a at the first gluing position 11a1 also follows the accommodating area 12a moving from the auxiliary station 1a to the second gluing position 11a2 and moves to the auxiliary station 1a, removing the glued paired bare cells 13 to realize unloading of the accommodating area 12a at the auxiliary station 1a, and reloading in the accommodating area 12a at the auxiliary station 1a, and the cycle continues. While the paired bare cells 13 in the receiving area 12a of the corresponding gluing position are being glued, the receiving area 12a at the auxiliary station 1a can be loaded or unloaded to fully utilize the time the bare cells 13 are waiting for gluing.

[0095] In the embodiment of the present disclosure, one accommodating area 12a can move synchronously with another accommodating area 12a. When the paired bare cells 13 in one accommodating area 12a move to the corresponding gluing position for gluing, the other accommodating area 12a can also move synchronously to the auxiliary workstation 1a for loading or unloading, further reducing the time the bare cells 13 wait for gluing, which is conducive to speeding up the gluing rhythm of the gluing system 1.

[0096] It is understood that the movement relationship between one of the two accommodating areas 12a and the other accommodating area 12a is not limited. For example, one accommodating area 12a moves relative to the other accommodating area 12a. After one accommodating area 12a moves to the corresponding gluing position, the other accommodating area 12a can move to the auxiliary station 1a. The two accommodating areas 12a are not relatively stationary.

[0097] In one embodiment, referring to FIG5 , the gluing system 1 further includes a detection component 14 , which is located between the first gluing station and the second gluing station along the first direction. The detection component 14 is used to detect the bare battery cell 13 in the accommodating area 12a of the auxiliary station 1a .

[0098] Exemplarily, the detection component 14 may include an image acquisition device, such as a camera or a webcam.

[0099] Exemplarily, the camera may be a CCD (Charge Coupled Device) camera.

[0100] In the disclosed embodiment, after loading into the receiving area 12a of the auxiliary station 1a, the inspection assembly 14 can inspect the paired bare cells 13 and reject any unqualified bare cells 13. After the bare cells 13 pass the inspection, the adhesive bonding process is performed on the bare cells 13, thereby avoiding wasting adhesive bonding time and adhesive resources and improving adhesive bonding efficiency.

[0101] In one embodiment, please refer to Figures 3 to 5, the detection component 14 has a detection part 141, the transverse movement mechanism 12 has an avoidance hole 12b connected to the corresponding accommodating area 12a, the detection part 141 is located below the avoidance hole 12b, the projection area of ​​the avoidance hole 12b corresponding to the accommodating area 12a located at the auxiliary workstation 1a along the up and down directions is the first area, the projection area of ​​the detection part 141 along the up and down directions is the second area, and the second area is located within the first area, so that the detection part 141 can detect the welding status of the adapter 132 through the avoidance hole 12b corresponding to the accommodating area 12a located at the auxiliary workstation 1a.

[0102] Exemplarily, the detection unit 141 may include a lens. For example, the lens may be a lens of a camera or a webcam.

[0103] Exemplarily, the auxiliary workstation 1a includes two sub-stations, each of which is provided with a detection component 14, wherein one accommodating area 12a switches between the first gluing position 11a1 and one of the sub-stations, and the other accommodating area 12a switches between the second gluing position 11a2 and another sub-station.

[0104] Exemplarily, the auxiliary workstation 1a is a sub-station, wherein one accommodating area 12a switches between the first gluing station 11a1 and the sub-station, and the other accommodating area 12a switches between the second gluing station 11a2 and the sub-station.

[0105] In the disclosed embodiment, since the adapter sheet 132 is located below the tab 131 of the bare cell 13 and is thicker than the tab 131 of the bare cell 13, if the thicker adapter sheet 132 can penetrate the thinner tab 131, the welding quality between the adapter sheet 132 and the tab 131 can be determined to be acceptable. Therefore, the detection unit 141 only needs to be located below the avoidance hole 12b and be able to detect the welding status below the adapter sheet 132 through the avoidance hole 12b to determine whether the welding quality of the bare cell 13 is acceptable. There is no need to set the detection unit 141 above the adapter sheet 132, which is beneficial to improving detection efficiency and saving internal space of the adhesive laminating system 1.

[0106] It is understandable that there is no limit to the position arrangement and number of the detection components 14. For example, the detection components 14 are arranged above and below the avoidance hole 12b connected to the accommodating area 12a located at the auxiliary station 1a.

[0107] It is understandable that the detection component 14 of the embodiment of the present disclosure is not limited to detecting the welding state. For example, the detection component 14 can also detect whether a bare battery cell 13 is placed in the accommodating area 12a.

[0108] Exemplarily, the detection component 14 may include a photoelectric sensor for detecting whether a bare battery cell 13 is placed in the accommodating area 12a.

[0109] In one embodiment, please refer to Figure 4, the glue application component 11 has a first glue preparation position 11b1 and a second glue preparation position 11b2, the first glue preparation position 11b1 and the second glue preparation position 11b2 are respectively used to obtain glue with different directions on the bonding side, the arrangement direction of the first glue preparation position 11b1 and the second glue preparation position 11b2 is the second direction, and the glue application position is located between the corresponding first glue preparation position 11b1 and the corresponding second glue preparation position 11b2 along the second direction.

[0110] It should be noted that the direction indicated by R2 in FIG. 4 is the second direction.

[0111] Exemplarily, the bonding side of the first glue preparation position 11 b 1 faces downward, and the glue obtained by the first glue preparation position 11 b 1 is used to bond above the bare battery cell 13 .

[0112] Exemplarily, the bonding side of the second glue preparation position 11b2 faces upward, and the glue obtained by the second glue preparation position 11b2 is used to bond to the bottom of the bare battery cell 13. The glue obtained by the second glue preparation position 11b2 spans the bare battery cell 13 and the adapter 132.

[0113] In the embodiment of the present disclosure, during the process of gluing the paired bare cells 13 in the accommodating area 12a located in the gluing position, the first glue preparation position 11b1 and the second glue preparation position 11b2 corresponding to the accommodating area 12a located in the auxiliary work station 1a can obtain glue with different bonding side directions. The first glue preparation position 11b1 obtains glue in one bonding side direction and the second glue preparation position 11b2 obtains glue in another direction without interfering with each other, which is conducive to improving the glue preparation efficiency.

[0114] For example, one of the accommodating areas 12a is moved to the auxiliary station 1a, and the paired bare cells 13 welded with the adapter 132 are placed in the accommodating area 12a located at the auxiliary station 1a, so as to realize the loading of the accommodating area 12a located at the auxiliary station 1a. The detection unit 141 detects the welding status of the adapter 132 through the avoidance hole 12b. After passing the test, the accommodating area 12a located at the auxiliary station 1a follows the transverse movement mechanism 12 to move along the first direction to the first gluing position 11a1 for gluing, and the accommodating area 12a located at the second station 1a is moved to the first gluing position 11a1 for gluing. The accommodating area 12a of the gluing position 11a2 moves from the auxiliary station 1a to the accommodating area 12a of the first gluing position 11a1 and moves to the auxiliary station 1a, and the other pair of bare cells 13 welded with the adapter 132 are placed in the accommodating area 12a located at the auxiliary station 1a, and the detection unit 141 detects the welding status of the adapter 132 through the avoidance hole 12b. After passing the inspection, the first glue preparation position 11b1 and the second glue preparation position 11b2 corresponding to the accommodating area 12a of the auxiliary station 1a start to prepare glue.

[0115] When the bare battery cells 13 in the accommodating area 12a of the first gluing position 11a1 complete the gluing action, the first glue preparation position 11b1 and the second glue preparation position 11b2 corresponding to the accommodating area 12a of the auxiliary station 1a also complete the gluing action, and the accommodating area 12a at the auxiliary station 1a will follow the transverse movement mechanism 12 to move along the first direction to the second glue preparation position 11a2 for gluing, and the accommodating area 12a at the first glue preparation position 11a1 follows the accommodating area 12a that moves from the auxiliary station 1a to the second glue preparation position 11a2 and moves to the auxiliary station 1a, removes the glued paired bare battery cells 13 and re-loads them in the accommodating area 12a at the auxiliary station 1a, and the detection unit 141 detects the welding status of the adapter 132 through the avoidance hole 12b. After passing the inspection, the first glue preparation position 11b1 and the second glue preparation position 11b2 corresponding to the accommodating area 12a of the auxiliary station 1a start to prepare glue, and the cycle continues. While the paired bare cells 13 are being glued, the other paired bare cells 13 to be glued can be inspected and prepared for glue, thus making full use of the time before the next bare cell 13 is glued.

[0116] It is understandable that the positional relationship between the first direction and the second direction is not limited. Exemplarily, the first direction is perpendicular to the second direction.

[0117] In one embodiment, referring to FIG. 1 to FIG. 5 , there are two gluing assemblies 11 , which are arranged opposite to each other, and the auxiliary station 1 a and a transverse movement mechanism 12 are both located between the two gluing assemblies 11 .

[0118] In the embodiment of the present disclosure, a transverse movement mechanism 12 is provided in the two gluing components 11, wherein one accommodating area 12a is located at the gluing position for gluing, the other accommodating area 12a is located at the auxiliary station 1a for loading and unloading, and the first glue preparation position 11b1 and the second glue preparation position 11b2 corresponding to the accommodating area 12a located at the auxiliary station 1a for glue preparation do not interfere with each other, so that the loading or unloading of the accommodating area 12a located at the auxiliary station 1a and the glue preparation of the first glue preparation position 11b1 and the second glue preparation position 11b2 corresponding to the accommodating area 12a located at the auxiliary station 1a fully utilize the gluing time of the paired bare batteries 13 in the accommodating area 12a located at the gluing position, which is beneficial to speed up the gluing rhythm of the gluing system 1.

[0119] Exemplarily, an auxiliary workstation 1a is arranged between the two gluing components 11. The auxiliary workstation 1a includes two sub-positions, one of which is located in the first gluing position 11a1 for gluing, and the other is located in the sub-position of the auxiliary workstation 1a close to the second gluing position 11a2 for loading and unloading.

[0120] In one embodiment, referring to Figures 1 and 2, the glue assembly 11 includes a glue device 111, and the glue device 111 includes a first glue part 1111, a second glue part 1112, a guide shaft and an elastic part 1114. One of the first glue part 1111 and the second glue part 1112 is connected to the guide shaft, and the other of the first glue part 1111 and the second glue part 1112 is movably arranged on the guide shaft. The elastic part 1114 is sleeved on the guide shaft, and the elastic part 1114 is in contact with the first glue part 1111 and the second glue part 1112 respectively.

[0121] Exemplarily, the cross-section of the second adhesive member 1112 parallel to the second direction is in a Z-shape.

[0122] Exemplarily, when the gluing device 111 moves downward to glue the tab 131, the first glue piece 1111 abuts the side of the bare battery cell 13 close to the tab 131, and the elastic piece 1114 is compressed so that the first glue piece 1111 is tightly attached to the upper side of the bare battery cell 13 close to the tab 131 and cannot continue to move downward. The second glue piece 1112 continues to move downward, extends into the avoidance groove formed by the tab 131 and the side of the bare battery cell 13 close to the tab 131 to glue the tab 131, and finally makes the cross-section of the colloid parallel to the second direction into a Z shape, and fully covers the tab 131 with the colloid to improve the bonding strength of the colloid at the tab 131.

[0123] After the gluing is completed, the gluing device 111 moves upward, the elastic member 1114 stretches, and the second gluing member 1112 moves upward under the elastic restoring force of the elastic member 1114. When the first gluing member 1111 leaves the bare battery cell 13, the gluing device 111 returns to its initial state.

[0124] Exemplarily, the gluing assembly 11 includes two gluing devices 111 , and the gluing devices 111 are provided on both the upper and lower sides of the accommodating area 12 a .

[0125] In the embodiment of the present disclosure, one end of the guide shaft is connected to the lower bottom surface of the top of the second adhesive member 1112, and the other end is connected to the upper top surface of the first adhesive member 1111. The elastic member 1114 is sleeved on the outside of the guide shaft, so that the first adhesive member 1111 can move along the axial direction of the guide shaft, so that the colloid can be completely and densely adhered to the tab 131 and the side of the bare battery cell 13 close to the tab 131.

[0126] Exemplarily, the gluing component 11 includes a frame and a drive assembly 112. The gluing device 111 is arranged on the frame so that the gluing device 111 can move along the frame between the gluing position and the standby position. The drive assembly 112 is arranged between the frame and the gluing device 111. The drive assembly 112 drives the gluing device 111 to glue the pairs of bare battery cells 13 in the corresponding accommodating area 12a.

[0127] For example, referring to Figure 1, the driving assembly 112 includes a first driving member 1121 and a second driving member 1122. The second driving member 1122 is installed on the first driving member 1121. The first driving member 1121 drives the second driving member 1122 to move in the second direction. The second driving member 1122 drives the gluing device 111 to move in the up and down directions to glue the bare battery cell 13.

[0128] Exemplarily, the first driving member 1121 is a linear module, and the first driving member 1121 drives the second driving member 1122 to move linearly.

[0129] For example, referring to Figure 1, the number of drive assemblies 112 of each gluing component 11 is two, one drive assembly 112 is located above the other drive assembly 112, the upper drive assembly 112 is used to drive the upper gluing device 111 to glue the upper part of the bare battery cell 13, and the lower drive assembly 112 is used to drive the lower gluing device 111 to glue the lower part of the bare battery cell 13.

[0130] In one embodiment, please refer to Figure 2, the first adhesive member 1111 has a first limiting portion 11111 and a first adhesive pressing surface 1111a for adhesive pressing, the second adhesive member 1112 has a second limiting portion 11121 and a second adhesive pressing surface 1112a for adhesive pressing, the first limiting portion 11111 is used to abut against the second limiting portion 11121 to limit the movement of the first adhesive member 1111 and the second adhesive member 1112 under the action of the elastic force of the elastic member 1114, when the first limiting portion 11111 and the second limiting portion 11121 abut, the first adhesive pressing surface 1111a and the second adhesive pressing surface 1112a are flush.

[0131] In the disclosed embodiment, the first glue pressing surface 1111a and the second glue pressing surface 1112a are flush, so that the glue can be evenly adsorbed on the glue applying device 111, which helps to reduce the difficulty of glue absorption by the glue applying device 111 at the corresponding glue preparation position.

[0132] It is understood that the positional relationship between the first pressing surface 1111a and the second pressing surface 1112a is not limited. For example, the first pressing surface 1111a and the second pressing surface 1112a may not be on the same horizontal plane.

[0133] The present disclosure also provides a method for applying glue. Referring to FIG. 7 , the method for applying glue includes:

[0134] Step S1 : driving one of the accommodating areas 12 a along a first direction from the auxiliary station 1 a between two glue-applying assemblies 11 to the glue-applying position of one of the glue-applying assemblies 11 by the transverse movement mechanism 12 .

[0135] Step S2 , gluing the bare battery cells 13 located in the receiving area 12 a corresponding to the gluing position using the gluing assembly 11 .

[0136] Step S3, before the bare battery cell 13 located in the accommodating area 12a corresponding to the gluing position completes gluing, another accommodating area 12a can reach the auxiliary station 1a from the gluing position of another gluing component 11, so that the bare battery cell 13 can be loaded to the accommodating area 12a corresponding to the auxiliary station 1a or unloaded from the accommodating area 12a corresponding to the auxiliary station 1a, and the two accommodating areas 12a of the transverse movement mechanism 12 are arranged along the first direction.

[0137] It can be understood that, among the two accommodating areas 12 a , the movement relationship of one accommodating area 12 a relative to the other accommodating area 12 a is not limited.

[0138] Exemplarily, the two accommodating areas 12a can move relative to each other, and one accommodating area 12a moves from the auxiliary workstation 1a to the corresponding gluing position. Before the bare battery cell 13 in the accommodating area 12a located at the corresponding gluing position completes gluing, the other accommodating area 12a is driven by the transverse movement mechanism 12 along the first direction to move from the gluing position of another gluing component 11 to the auxiliary workstation 1a.

[0139] For example, the two accommodating areas 12a may be relatively stationary and cannot move relative to each other. When one of the accommodating areas 12a is driven by the transverse movement mechanism 12 along the first direction from the auxiliary station 1a to the gluing position of one of the gluing assemblies 11, the other accommodating area 12a is immediately driven by the transverse movement mechanism 12 from the corresponding gluing position to the auxiliary station 1a.

[0140] The gluing method provided by the embodiment of the present disclosure switches between the gluing position and the auxiliary station 1a through two accommodating areas 12a. When one of the accommodating areas 12a is located at the corresponding gluing position and the other accommodating area 12a is located at the auxiliary station 1a, the gluing time of the bare battery cells 13 in the accommodating area 12a located at the corresponding gluing position can be fully utilized, and the bare battery cells 13 in the accommodating area 12a located at the auxiliary station 1a can be loaded or unloaded, which is conducive to speeding up the gluing rhythm of the gluing assembly 11.

[0142] In one embodiment, the gluing assembly 11 includes a gluing device 111, and the gluing method further includes:

[0143] Step S4 : when one of the accommodating areas 12 a is located at the corresponding gluing position, the gluing device 111 of the gluing assembly 11 corresponding to the other accommodating area 12 a is prepared for gluing.

[0144] In the disclosed embodiment, the transverse movement mechanism 12 is moved to move one of the receiving areas 12a to the corresponding gluing position, and the corresponding gluing device 111 is also moved to the corresponding gluing position. The other receiving area 12a is then moved to the auxiliary station 1a, and the corresponding gluing device 111 is then moved to the corresponding gluing preparation position for gluing. This allows the gluing system 1 to fully utilize the time it takes to glue one pair of bare cells 13 to prepare glue for the next pair of bare cells 13, which helps speed up the gluing process of the gluing system 1.

[0145] In one embodiment, the adapter sheet 132 corresponding to the bare battery cell 13 in the accommodation area 12a is inspected by the inspection component 14, and the adhesive application method further includes:

[0146] In step S5 , when one of the receiving areas 12 a is located at the corresponding gluing position, the detection component 14 detects the adapter 132 corresponding to the bare cell 13 in the receiving area 12 a of the auxiliary station 1 a .

[0147] In the disclosed embodiment, the traverse mechanism 12 is moved to move one of the receiving areas 12a to the corresponding gluing position. The corresponding gluing device 111 is also moved to the corresponding gluing position. The other receiving area 12a is then moved to the auxiliary station 1a. The inspection component 14 inspects the bare cells 13 located in the receiving area 12a of the auxiliary station 1a. Based on the inspection results, the subsequent gluing steps are performed, thus avoiding wasting glue resources and gluing time.

[0148] In one embodiment, the detection component 14 has a detection portion 141, and the lateral movement mechanism 12 has an avoidance hole 12b. When one of the accommodating areas 12a is located at the corresponding glue-applying position, the detection component 14 detects the adapter 132 corresponding to the bare battery cell 13 located in the accommodating area 12a of the auxiliary station 1a, including the following steps:

[0149] In step S51 , when one of the accommodating areas 12 a is located at the corresponding gluing position, the detection unit 141 is used to detect the welding status of the adapter plate 132 in the accommodating area 12 a of the auxiliary station 1 a through the avoidance hole 12 b .

[0150] Exemplarily, the detection unit 141 may include a lens. For example, the lens may be a lens of a camera or a webcam.

[0151] In the embodiment of the present disclosure, the pair of bare cells 13 are placed in the accommodating area 12a located at the auxiliary workstation 1a, and the detection unit 141 will detect the weld of the adapter plate 132 through the avoidance hole 12b, and then determine whether to discard the pair of bare cells 13 based on the quality of the weld of the adapter plate 132.

[0152] An embodiment of the present disclosure further provides a battery production line, comprising the gluing system 1 , a loading mechanism, and a unloading mechanism according to any one of the above embodiments.

[0153] In the embodiment of the present disclosure, the loading mechanism is used to place the welded pairs of bare cells 13 into the accommodation area 12a of the auxiliary workstation 1a, and the unloading mechanism is used to move the pairs of bare cells 13 that have completed gluing out from the accommodation area 12a of the auxiliary workstation 1a, which is beneficial to improving the production efficiency of the battery.

[0154] The foregoing description is merely a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
