Description

Technical Field

[0001] This application relates to the field of battery manufacturing, and in particular to a device for removing adhesive from battery modules. Background Technology

[0002] In recent years, new energy vehicles have experienced rapid development. In the field of electric vehicles, batteries, as the power source, play an irreplaceable and crucial role. A battery consists of a casing and battery modules housed within it. To ensure reliable connection between the battery modules and the casing, adhesive is typically applied between them. However, this application of adhesive can easily lead to residual adhesive forming on the top of the battery modules, affecting battery reliability. Utility Model Content

[0003] This application provides a battery module adhesive removal device, which can remove adhesive from the battery module, thereby improving the reliability of the battery.

[0004] This application provides a battery module adhesive removal device, including: an adhesive removal section, including an adhesive removal drive assembly, an adhesive removal component, and a force detection component, wherein the adhesive removal drive assembly is connected to the adhesive removal component to drive the adhesive removal component to move and remove adhesive, and the force detection component is disposed on the adhesive removal component to detect the force exerted on the adhesive removal component during adhesive removal in real time; and a moving section, connected to the adhesive removal drive assembly to drive the adhesive removal section to move to the adhesive removal working position.

[0005] In the above technical solution, the adhesive removal device can mechanically remove adhesive from the battery module through the adhesive removal section, which can improve the adhesive removal efficiency. Mechanical adhesive removal also has high operational reliability and helps maintain adhesive removal consistency, resulting in better adhesive removal effects and improving the reliability of the battery module and battery. Furthermore, the adhesive removal section can monitor the adhesive removal force in real time during the adhesive removal process, thereby improving adhesive removal safety and reducing the probability of damage to the battery module during adhesive removal, further enhancing the reliability of the battery module and battery. The adhesive removal device can also move the adhesive removal section into or out of the adhesive removal working position via a moving part, reducing manual operation steps and increasing the automation level of battery module adhesive removal.

[0006] In some embodiments of this application, the adhesive removal drive assembly drives the adhesive removal assembly to move along a first direction and remove adhesive. There are multiple adhesive removal assemblies, which are spaced apart along a second direction, which is perpendicular to the first direction.

[0007] In the above technical solution, by setting multiple adhesive removal components spaced apart, the residual adhesive in the battery module can be precisely removed. This reduces the chance of damaging the battery module while removing the adhesive, thus improving its reliability. Furthermore, in this solution, each adhesive removal component can be made relatively small while fulfilling its adhesive removal function, which increases the travel distance of the component and makes the removal of residual adhesive more thorough.

[0008] In some embodiments of this application, the adhesive removal drive assembly includes: a fixed base connected to a movable part; a first drive member, wherein there are multiple first drive members disposed on the fixed base and arranged sequentially along a second direction, and the number of first drive members and adhesive removal assembly are equal and connected in a one-to-one correspondence.

[0009] In the above technical solution, the number of first driving components and adhesive removal components are equal and connected in a one-to-one correspondence. Thus, each adhesive removal component has an independent driving component, which is beneficial to improve the flexibility and scalability of the adhesive removal section, facilitates more precise adhesive removal from the battery module, and reduces the probability of the entire system being paralyzed due to the failure of a single component. This can enhance the system reliability and fault tolerance of the adhesive removal section.

[0010] In some embodiments of this application, the adhesive removal assembly includes: a connecting seat for connecting the adhesive removal drive assembly; and an adhesive removal component having a blade for adhesive removal and being elastically and movably disposed on the connecting seat along a third direction, wherein the third direction, the second direction, and the first direction are perpendicular to each other.

[0011] In the above technical solution, by configuring the adhesive removal assembly to include a connector and an adhesive removal component, the structural complexity of the adhesive removal assembly can be reduced. The connector and adhesive removal component can be manufactured separately, reducing processing difficulty and manufacturing costs. Since the adhesive removal assembly has a split structure, if one component fails, only the damaged component needs to be replaced, facilitating replacement and maintenance and reducing operating costs. Furthermore, the adhesive removal component is elastically movable along a third direction on the connector. This reduces the probability of rigid collisions between the adhesive removal component and the surface of the battery module, minimizing the risk of damage to the adhesive removal component and / or the battery module. It also allows the adhesive removal component to firmly abut against the surface of the battery module, enhancing its effectiveness in removing residual adhesive.

[0012] In some embodiments of this application, the adhesive removal assembly includes: a guide member connecting the connector and the adhesive removal component to allow the adhesive removal component to move relative to the connector in a third direction; and an elastic member disposed between the adhesive removal component and the connector.

[0013] In the above technical solution, by setting a guide component between the connector and the adhesive removal component, the reliability of the adhesive removal component's movement relative to the connector in a third direction can be improved, thus enhancing the overall structural reliability of the adhesive removal assembly. By setting an independent elastic component, the way the adhesive removal component achieves elastic movement relative to the connector in a third direction is relatively simple and reliable. In other words, the adhesive removal assembly adopts the above structure, which is simple and possesses good overall reliability, thus contributing to improved system stability.

[0014] In some embodiments of this application, the guide component is a guide post. Except for the rubber part and the connecting seat, one of which has a guide hole and the other is connected to the guide component, the guide component passes through the guide hole, and the elastic element is cylindrical and sleeved on the guide component.

[0015] In the above technical solution, the guide component and elastic element have simple structures and a low probability of failure, which helps to improve the overall reliability of the adhesive removal assembly. Moreover, the simple structure of the guide component and elastic element facilitates maintenance and repair, reduces operating costs, and also facilitates manufacturing and assembly.

[0016] In some embodiments of this application, the adhesive removal drive assembly includes a fixed base and a first drive member. The fixed base is connected to the movable part, and the first drive member is disposed on the fixed base and drives the adhesive removal assembly to move and remove adhesive. The adhesive removal part also includes a residual adhesive collection assembly, which is disposed on the fixed base and located on the side of the adhesive removal assembly away from the first drive member, for collecting the residual adhesive removed by the adhesive removal assembly.

[0017] In the above technical solution, by setting up a residual adhesive collection component, the residual adhesive particles removed by the adhesive removal component can be collected. On the one hand, this reduces the probability of residual adhesive particles falling into the battery and causing pollution, and also reduces the probability of residual adhesive particles falling into the surrounding environment and polluting the manufacturing workshop. On the other hand, it is also conducive to the recycling and reuse of residual adhesive particles, which can reduce the production cost of the battery.

[0018] In some embodiments of this application, the adhesive removal assembly includes an adhesive removal element having a blade for removing adhesive, and the residual adhesive collection assembly includes: a collection container having a top surface flush with the bottom surface of the adhesive removal element and having an opening; a cover plate covering the opening; and a second driving member disposed on the collection container and connected to the cover plate to drive the cover plate to open the opening.

[0019] In the above technical solution, by setting the residual adhesive collection component into the aforementioned structure, the structure is relatively simple, easy to manufacture and process, and the cost can be reduced. By making the top surface of the collection container flush with the bottom surface of the adhesive removal component, the removed residual adhesive particles can enter the collection container more smoothly, reducing the travel distance of the particles and thus lowering the probability of them falling outside the container, thereby improving the residual adhesive particle collection effect.

[0020] In some embodiments of this application, the adhesive removal drive assembly includes a limiting member, which is disposed on a fixed base and has a limiting space for positioning the battery module. The residual adhesive collection assembly is connected to the fixed base through the limiting member.

[0021] In the above technical solution, by setting a limiting component, the limiting space formed by the limiting component can play a role in positioning and restricting the movement of the battery module, thereby reducing the probability of the battery module moving when the adhesive is removed and improving the reliability of adhesive removal.

[0022] In some embodiments of this application, the fixed base is connected to the end effector of the moving part via a force detection element. In this technical solution, the force detection element can not only monitor the force transmitted from the adhesive removal component to the adhesive removal drive component in real time, but also monitor the force exerted by the moving part on the adhesive removal drive component in real time. The force detection path is relatively simple, and it is easier and more convenient to detect the force during the adhesive removal process, thus improving the force detection effect.

[0023] In some embodiments of this application, the movable part includes a base and a movable component. The movable component is disposed on the base and configured to drive the adhesive removal part to move along a first direction, a second direction, and a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. The adhesive removal drive assembly drives the adhesive removal part to move along the first direction and remove adhesive.

[0024] In the above technical solution, the base can provide better support for the moving parts, improve the overall support stability of the moving parts on the ground, and by configuring the moving parts to drive the de-adhesion part to move along the first direction, the second direction and the third direction, the moving parts can perform multi-axis movement, which has higher flexibility and adaptability, a wider range of movement and more precise adjustment capability. This is conducive to adjusting the de-adhesion part to a de-adhesion working position suitable for de-adhesion of battery modules and can adapt to de-adhesion operations in complex situations.

[0025] In some embodiments of this application, the first direction and the second direction are parallel to the horizontal plane, and the force detection element is configured to detect the force on the adhesive removal assembly in the first direction and the second direction at least in real time.

[0026] In the above technical solution, the force detection component is configured to detect the force on the adhesive removal component in at least real time in the first and second directions. On the one hand, it can obtain the force information of the adhesive removal component in the two main directions in the plane, so as to more comprehensively and accurately grasp the force state, which is conducive to ensuring the stable adhesive removal of the adhesive removal component. On the other hand, it can also accurately control and adjust the force applied by the adhesive removal component during adhesive removal based on the force situation in at least two directions, thereby improving the reliability and accuracy of adhesive removal and improving the safety of the operation.

[0027] In some embodiments of this application, the moving part is a multi-degree-of-freedom robotic arm, and the end effector of the multi-degree-of-freedom robotic arm is connected to a glue removal drive assembly.

[0028] In the above technical solution, the multi-degree-of-freedom robotic arm can perform various complex movements in three-dimensional space, has high adjustment precision, and can perform more precise operations. This is beneficial for adapting to the position of the battery module and adjusting the posture of the adhesive removal section, thereby smoothly adjusting the adhesive removal section to the adhesive removal working position. Moreover, the multi-degree-of-freedom robotic arm has good operational precision and force controllability, which can ensure the stability and consistency of multiple positioning of the adhesive removal section. It can also perform tasks quickly and continuously, which helps to reduce the work cycle and improve work efficiency. Attached Figure Description

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0055] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0056] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0057] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0058] In this application, "multiple" means two or more (including two).

[0059] The battery module mentioned in the embodiments of this application refers to a single physical module comprising one or more battery cells to provide higher voltage and capacity. A battery module can refer to one of the main components of a battery; for example, a battery generally includes a battery module and a housing for encapsulating one or more battery modules. The housing can prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells. As an example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0060] In this application, the battery cell may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and the embodiments of this application are not limited to these. The battery cell may be cylindrical, flat, cuboid, or other shapes, etc., and the embodiments of this application are not limited to these. Battery cells are generally divided into three types according to their packaging method: cylindrical battery cells, square battery cells, and pouch battery cells, and the embodiments of this application are not limited to these.

[0061] A single battery cell includes a casing, electrode assembly, and electrolyte. The casing houses the electrode assembly and electrolyte. The electrode assembly consists of a positive electrode, a negative electrode, and a separator. The battery cell primarily functions by the movement of metal ions between the positive and negative electrode plates. The positive electrode includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive current collector, while the uncoated positive current collector protrudes beyond the coated one, serving as the positive electrode tab. Taking a lithium-ion battery as an example, the positive current collector can be made of aluminum, and the positive active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc. The negative electrode includes a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative current collector, and the negative current collector without the negative active material layer protrudes from the one with the negative active material layer. The negative current collector without the negative active material layer serves as the negative electrode tab. The material of the negative current collector can be copper, and the negative active material can be carbon or silicon, etc. To ensure that a large current can be passed without melting, there are multiple positive electrode tabs stacked together, and there are multiple negative electrode tabs stacked together.

[0062] The separator can be made of PP (polypropylene) or PE (polyethylene), etc. Furthermore, the electrode assembly can be a wound structure or a stacked structure; the embodiments of this application are not limited to these.

[0063] In recent years, new energy vehicles have experienced rapid development. In the field of electric vehicles, batteries, as the power source, play an irreplaceable and crucial role. A battery consists of a casing and multiple individual battery cells housed within it. As a core component of new energy vehicles, batteries have high requirements in terms of both safety and cycle life.

[0064] In typical batteries, adhesive is applied between the battery module and the casing to ensure a more reliable connection. However, because a battery module consists of multiple individual cells, and the sidewalls of these cells are rounded during manufacturing, a significant gap can form between any two adjacent cells in the outermost row of the module. After the module is installed in the casing, the adhesive can overflow along these gaps, leaving residue. This residue can hinder heat conduction and dissipation within the battery module, create irregular bumps or foreign objects on its surface, increasing the risk of short circuits between the positive and negative terminals. Furthermore, inconsistent adhesive levels in different areas can lead to performance variations across different parts of the battery module, affecting its overall consistency and performance. Therefore, failure to effectively remove residual adhesive from the battery module can negatively impact battery reliability, performance, and lifespan.

[0065] Based on the above considerations, in order to solve the problem of how to remove residual adhesive from battery modules, the applicant designed an adhesive removal device for battery modules, including an adhesive removal part and a moving part. The adhesive removal part includes an adhesive removal drive component, an adhesive removal component, and a force detection component. The adhesive removal drive component is connected to the adhesive removal component to drive the adhesive removal component to move and remove adhesive. The force detection component is set on the adhesive removal component to detect the force exerted on the adhesive removal component during adhesive removal in real time. The moving part is connected to the adhesive removal drive component to drive the adhesive removal part to move to the adhesive removal working position.

[0066] In this type of battery module adhesive removal device, the adhesive removal component is driven to move by the adhesive removal drive assembly, enabling mechanical removal of residual adhesive from the battery module. This method boasts high removal efficiency and reliable operation, effectively removing residual adhesive and improving the reliability of the battery module, thereby enhancing battery reliability. Force detection components allow for real-time monitoring of the forces exerted on the battery module by the adhesive removal component during removal, facilitating better control of the applied force and reducing the likelihood of excessive force damaging the insulation structure or other components of the battery module surface, further improving the reliability of the battery module and battery. The moving part allows the adhesive removal component to move to the adhesive removal working position when needed and move out of the working position when not needed, thus facilitating automated operation of the adhesive removal device.

[0067] The adhesive removal device for battery modules disclosed in this application can also be applied to automated battery production equipment. As a device in a certain stage of automated battery production equipment, the adhesive removal device can improve the applicability of the adhesive removal device for battery modules.

[0068] Please refer to Figure 1 , Figure 1 This is an exploded view of the structure of a battery 200 provided in some embodiments of this application. The battery 200 includes a housing 210 and a plurality of battery modules 220, which are housed within the housing 210. The housing 210 provides assembly space for the battery modules 220, and the housing 210 can adopt various structures. In some embodiments, the housing 210 may include a first housing body 211 and a second housing body 212, which overlap each other, and together define an assembly space for accommodating the battery modules 220. The second box body 212 can be a hollow structure open at one end, and the first box body 211 can be a plate-like structure. The first box body 211 covers the open side of the second box body 212 so that the first box body 211 and the second box body 212 together define the assembly space. Alternatively, the first box body 211 and the second box body 212 can both be hollow structures open on one side, with the open side of the first box body 211 covering the open side of the second box body 212. Of course, the box 210 formed by the first box body 211 and the second box body 212 can be of various shapes, such as a cylinder, a cuboid, etc.

[0069] The battery module 220 may include multiple battery cells 221, which can be connected in series, parallel, or in a hybrid configuration. A hybrid configuration means that some of the battery cells 221 are connected in series and others in parallel. The multiple battery cells 221 can be directly connected in series, parallel, or in a hybrid configuration, and then the entire assembly of the multiple battery cells 221 is housed within the housing 210. Alternatively, the battery 200 can also be formed by first connecting multiple battery cells 221 in series, parallel, or in a hybrid configuration to create a battery module, and then connecting these battery modules in series, parallel, or in a hybrid configuration to form a whole, which is also housed within the housing 210. The battery 200 may also include other structures; for example, the battery 200 may include a busbar component for electrical connection between the multiple battery cells 221.

[0070] Please refer to Figure 1 , Figure 1This is a partial structural diagram of a battery 200 provided in some embodiments of this application. The battery 200 includes multiple battery modules 220, and each battery module 220 may include multiple rows of battery cells 221. The multiple rows of battery cells 221 may be arranged along the length direction of the housing 210, and each row of battery cells 221 may include multiple battery cells 221 arranged along the width direction of the housing 210; or, the multiple rows of battery cells 221 may be arranged along the width direction of the housing 210, and each row of battery cells 221 may include multiple battery cells 221 arranged along the length direction of the housing 210.

[0071] Each battery cell 221 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited to these. The battery cell 221 can be cylindrical, flat, cuboid, or other shapes. For example, see [reference needed]. Figure 1 The shape of the battery cell 221 is a cuboid.

[0072] According to some embodiments of this application, refer to Figure 2 This application provides a de-adhesive removal device 100 for a battery module 220, including a de-adhesive removal part 10 and a moving part 20.

[0073] The adhesive removal section 10 includes an adhesive removal drive assembly 11, an adhesive removal assembly 12, and a force detection element 13. The adhesive removal drive assembly 11 is connected to the adhesive removal assembly 12 to drive the adhesive removal assembly 12 to move and remove adhesive. The force detection element 13 is disposed on the adhesive removal assembly 12 to detect the force exerted on the adhesive removal assembly 12 during adhesive removal in real time. The moving section 20 is connected to the adhesive removal drive assembly 11 to drive the adhesive removal section 10 to the adhesive removal working position.

[0074] The adhesive removal drive assembly 11 can refer to a drive component used to drive the adhesive removal assembly 12 to reciprocate, so as to provide the adhesive removal assembly 12 with the force to scrape or scrape the adhesive. The adhesive removal drive assembly 11 can be, but is not limited to, a pneumatic drive assembly, a hydraulic drive assembly, a motor drive assembly, an electromagnetic drive assembly, etc.

[0075] The adhesive removal component 12 can refer to a component used to scrape or remove adhesive from the battery module 220.

[0076] Force detection component 13 can refer to a component capable of detecting one or more parameters such as the magnitude, direction, and change of force. Force detection component 13 can be, but is not limited to, strain gauges, sensors, etc. For example, force detection component 13 can be a force-controlled sensor. Force detection component 13 can monitor the force exerted on the adhesive removal assembly 12 by the battery module 220 in real time and can send a signal. After receiving the signal, the adhesive removal drive assembly 11 can adjust the force applied to the adhesive removal assembly 12 by the adhesive removal drive assembly 11 through its controller or its own control circuit.

[0077] In the above solution, by setting the force detection component 13, the probability of ineffective glue removal due to insufficient force of the glue removal component 12 can be reduced. On the other hand, since the housing 210 and the battery cell 221 are generally equipped with insulation structures, for example, the side wall of the housing 210 is generally coated with insulating paint, the surface of the battery cell 221 is generally covered with a blue film, and there are other components on the battery module 220, such as busbars or acquisition circuits, the force detection component 13 can control the glue removal force of the glue removal component 12, which helps to reduce the probability of damage to the insulation structure of the housing 210 and / or the battery cell 221, as well as other components on the battery module 220, due to excessive force of the glue removal component 12.

[0078] For example, the force exerted by the adhesive removal component 12 on the battery module 220 can be preset with a safety value. When the force detection component 13 detects that the force value is greater than or equal to the safety value, the adhesive removal device 100 can alarm and stop, which helps to improve safety.

[0079] In other words, by configuring the adhesive removal section 10 to include an adhesive removal drive assembly 11, an adhesive removal assembly 12, and a force detection element 13, the adhesive removal drive assembly 11 can mechanically remove adhesive from the battery module 220 by driving the adhesive removal assembly 12 to move. Compared with manual adhesive removal, this method has higher adhesive removal efficiency, more stable and reliable operation, and higher adhesive removal safety. The force detection element 13 monitors in real time the force exerted by the adhesive removal assembly 12 on the battery module 220 during adhesive removal, which helps reduce the probability of damage to the battery module 220 and / or the housing 210 during the adhesive removal process, reducing the risk of functional damage to the battery module 220 and the housing 210, and improving the reliability of the battery module 220 and the battery 200. Furthermore, since the adhesive removal section 10 performs mechanical adhesive removal, the real-time monitoring of the adhesive removal force of the adhesive removal assembly 12 by the force detection element 13 also helps to control the adhesive removal process and improve operational safety.

[0080] The moving part 20 can refer to a mechanism that can drive the entire adhesive removal part 10 to move. The moving part 20 can be, but is not limited to, a moving worktable, a multi-degree-of-freedom robot, etc. The "adhesive removal workstation" can refer to the position where the adhesive removal part 10 removes adhesive from the battery module 220. The position of the adhesive removal part 10 away from the battery module 220 can be called the non-adhesive removal workstation. When the battery 200 reaches the target position, the adhesive removal part 10 may be in the non-adhesive removal workstation. At this time, the moving part 20 can drive the adhesive removal part 10 to the adhesive removal workstation, enabling the adhesive removal part 10 to remove adhesive from the battery module 220. After adhesive removal is completed, the moving part 20 can drive the adhesive removal part 10 back to the non-adhesive removal workstation, thus not affecting the next operation of the battery module 220.

[0081] As can be seen from the above, by the cooperation of the moving part 20 and the adhesive removal part 10, the adhesive removal device 100 can be moved to the position of the battery module 220 and remove adhesive from the battery module 220. The degree of mechanization is relatively high and the degree of automation is relatively high, which is conducive to the automation of adhesive removal from the battery module 220.

[0082] In the above technical solution, the adhesive removal device 100 can mechanically remove adhesive from the battery module 220 through the adhesive removal section 10, which can improve the adhesive removal efficiency. Mechanical adhesive removal also has high operational reliability and helps maintain adhesive removal consistency, resulting in better adhesive removal effects and improving the reliability of the battery module 220 and the battery 200. Furthermore, the adhesive removal section 10 can monitor the adhesive removal force in real time during the adhesive removal process, thereby improving adhesive removal safety and reducing the probability of damage to the battery module 220 during adhesive removal, further enhancing the reliability of the battery module 220 and the battery 200. The adhesive removal device 100 can also move the adhesive removal section 10 into or out of the adhesive removal working position via the moving part 20, reducing manual operation steps and increasing the automation level of adhesive removal from the battery module 220.

[0083] In some embodiments of this application, reference is made to Figure 3 and Figure 4 The adhesive removal drive assembly 11 drives the adhesive removal assembly 12 to move along the first direction X and remove adhesive. There are multiple adhesive removal assemblies 12, which are spaced apart along the second direction Y, which is perpendicular to the first direction X.

[0084] To better understand this solution, the first direction X and the second direction Y can be described in conjunction with the battery module 220. For example, the battery module 220 may include multiple rows of battery cells 221, arranged along the first direction X, with each row of multiple battery cells 221 arranged along the second direction Y. Because the outer edges of the battery cell 221 have rounded corners, adhesive will overflow from the gaps formed between adjacent battery cells 221 and the housing 210, forming residual adhesive on the surface of the battery module 220. In other words, the residual adhesive is concentrated at the rounded corners of adjacent battery cells 221.

[0085] By setting multiple adhesive removal components 12 along the second direction Y, each adhesive removal component 12 can remove residual adhesive between two adjacent battery cells 221. This allows for targeted adhesive removal of the battery module 220, removing adhesive only from areas where residual adhesive exists, while omitting areas where no adhesive remains. This method enables precise adhesive removal of the battery module 220, reducing the contact area between the adhesive removal component 12 and the surface of the battery cells 221, and lowering the probability of the adhesive removal component 12 damaging the battery cells 221 during the removal process. For example, reducing the contact area between the adhesive removal component 12 and the insulating film on the surface of the battery cells 221 also reduces the likelihood of significant damage to the insulating film.

[0086] Since the top surface of the battery cell 221 is generally provided with a terminal post, when the residual adhesive is large in the first direction X of the battery cell 221, causing the residual adhesive part to be between the terminals of two adjacent battery cells 221, since there are multiple adhesive removal components 12, the size of each adhesive removal component 12 in the second direction Y can be made relatively small. The adhesive removal drive component 11 can drive the adhesive removal component 12 to move a greater distance in the first direction X, and the adhesive removal component 12 can more easily enter between the terminals of two adjacent battery cells 221, which is beneficial to cleanly remove the residual adhesive between the two battery cells 221.

[0087] Secondly, compared to making the adhesive removal component 12 a larger component and removing adhesive from multiple battery cells 221 at the same time, the above-mentioned solution of making multiple adhesive removal components 12 and removing adhesive from multiple battery cells 221 separately can reduce the amount of material used in the adhesive removal component 12 and reduce material costs.

[0088] In the above technical solution, by setting multiple adhesive removal components 12 at intervals, the residual adhesive on the battery module 220 can be precisely removed. This reduces the likelihood of damaging the battery module 220 while removing the adhesive, thus improving its reliability. Furthermore, in this solution, each adhesive removal component 12 can be made relatively small while fulfilling its adhesive removal function, which increases the travel distance of the component and allows for more thorough removal of residual adhesive.

[0089] In some embodiments of this application, reference is made to Figure 3 , Figure 4 and Figure 5 The adhesive removal drive assembly 11 includes a fixed base 111 and a first drive member 112. The fixed base 111 is connected to the moving part 20. There are multiple first drive members 112, which are disposed on the fixed base 111 and arranged sequentially along the second direction Y. The number of first drive members 112 and adhesive removal assembly 12 are equal and they are connected in a one-to-one correspondence.

[0090] The mounting base 111 can refer to a structural member used to provide an installation position for the first drive member 112 and to connect with the movable part 20. The mounting base 111 can be, but is not limited to, a plate structure, a frame structure, etc. For example, see... Figure 5 The fixed base 111 can be a frame.

[0091] The first driving element 112 can refer to a driving component that drives the adhesive removal assembly 12 to reciprocate and remove adhesive. The first driving element 112 can be, but is not limited to, a pneumatic telescopic component, a hydraulic telescopic component, an electric telescopic component, or a magnetic telescopic component, etc. Exemplarily, the first driving element 112 can be a cylinder. In this example, the adhesive removal driving assembly 11 can also include a control component 114 that controls the operation of multiple cylinders (see...). Figure 3 , Figure 4and Figure 5 Optionally, the control component 114 can be a valve island.

[0092] The phrase "the number of first driving components 112 and adhesive removal components 12 are equal and connected in a one-to-one correspondence" can be understood as follows: the number of first driving components 112 and adhesive removal components 12 are the same, each first driving component 112 is connected to a corresponding adhesive removal component 12, and can drive the corresponding adhesive removal component 12 to reciprocate and remove adhesive. In this way, each adhesive removal component 12 can be independently controlled and adjusted. For example, combined with visual inspection, the force and travel of each adhesive removal component 12 can be selectively adjusted according to the size and thickness of each piece of residual adhesive, which is beneficial for more precise removal of residual adhesive from the battery module 220. On the other hand, when one or more first driving components 112 fail, the other first driving components 112 can still work normally, which can reduce the probability of multiple adhesive removal components 12 failing as a whole, thus enhancing the system reliability and fault tolerance of the adhesive removal section 10. Furthermore, since multiple adhesive removal components 12 are driven by independent first driving components 112, it also facilitates maintenance personnel to more quickly locate and resolve faults, reducing downtime.

[0093] In the above technical solution, the number of first driving components 112 and adhesive removal components 12 are equal and connected in a one-to-one correspondence. Thus, each adhesive removal component 12 has an independent driving component, which is beneficial to improve the flexibility and scalability of the adhesive removal section 10, facilitates more precise adhesive removal from the battery module 220, and reduces the probability of the entire system being paralyzed due to the failure of a single component. This can enhance the system reliability and fault tolerance of the adhesive removal section 10.

[0094] In some embodiments of this application, reference is made to Figure 6 The adhesive removal assembly 12 includes a connecting seat 121 and an adhesive removal component 122. The connecting seat 121 is connected to the adhesive removal drive assembly 11. The adhesive removal component 122 has a blade 122a for adhesive removal and is elastically and movably disposed on the connecting seat 121 along the third direction Z. The third direction Z, the second direction Y, and the first direction X are perpendicular to each other.

[0095] The connecting seat 121 can refer to a structural member that provides an installation position for the adhesive remover 122 and is connected to the fixing seat 111. The connecting seat 121 can be, but is not limited to, a plate-like member, a rod-like member, or a frame member. For example, see... Figure 5 Connector 121 is an L-shaped plate.

[0096] The adhesive removal component 122 can refer to a part that acts on the battery module 220 to remove adhesive. The blade 122a can refer to a relatively sharp part of the adhesive removal component 122; for example, the blade 122a is a tapered sharp part of the adhesive removal component 122. The blade 122a removes residual adhesive from the surface of the battery module 220 by acting on it. Specifically, the adhesive removal component 122 can refer to a scraper, spatula, etc.

[0097] The phrase "the adhesive remover 122 is elastically movably mounted on the connecting seat 121 along the third direction Z" can be understood as meaning that the adhesive remover 122 can move relative to the connecting seat 121 along the third direction Z, and there is an elastic force between them. The connection between the adhesive remover 122 and the connecting seat 121 can be, but is not limited to, a spring connection, a spring-loaded connection, etc. For example, a spring can be arranged along the third direction Z, with its two ends connected to the adhesive remover 122 and the connecting seat 121 respectively. Another example is a bent metal sheet, arranged along the third direction Z, with its two ends connected to the adhesive remover 122 and the connecting seat 121 respectively.

[0098] In the above technical solution, by configuring the adhesive removal assembly 12 to include a connector 121 and an adhesive removal component 122, the structural complexity of the adhesive removal assembly 12 can be reduced. The connector 121 and the adhesive removal component 122 can be manufactured separately, reducing processing difficulty and manufacturing costs. Since the adhesive removal assembly 12 has a split structure, if one component is damaged, only the damaged component needs to be replaced, which facilitates replacement and maintenance and reduces usage costs. The adhesive removal component 122 is elastically and movably disposed on the connector 121 along the third direction Z. This reduces the probability of rigid collision between the adhesive removal component 122 and the surface of the battery module 220, reducing the risk of damage to the adhesive removal component 122 and / or the battery module 220. It also allows the adhesive removal component 122 to be firmly abutted against the surface of the battery module 220, enhancing the adhesive removal effect of the adhesive removal component 122.

[0099] In some embodiments of this application, reference is made to Figure 6 The bottom of the blade 122a has a recess 122c. In this technical solution, by providing a recess 122c at the bottom of the blade 122a, the contact area between the bottom surface of the blade 122a and the battery cell 221 is relatively small, which helps to reduce friction. Moreover, the bottom of the blade 122a can have a sharp structure, which helps to improve the sharpness of the blade 122a and enhance the descaling effect on the battery module 220.

[0100] In some embodiments of this application, reference is made to Figure 3 and Figure 6The adhesive removal component 122 can be a scraper. This can be understood as a scraper-like structure, where the top of the bevel formed by the blade 122a is inclined towards the side closer to the first driving member 112 compared to the bottom. This structure allows the adhesive removal component 122 to more effectively remove stubborn or thick adhesive residue, and also makes it easier to remove large pieces of adhesive residue, thus possessing stronger adhesive removal capabilities. Furthermore, when the adhesive removal component 122 is a scraper, the force applied during scraping is relatively uniform, and when dealing with some hard adhesive residue, it is less likely to cause excessive scratches or damage to the surface of the battery module 220, which helps improve the reliability of the battery module 220.

[0101] In some embodiments of this application, reference is made to Figure 5 The adhesive removal assembly 12 includes a guide member 123 and an elastic member 124. The guide member 123 connects the connecting seat 121 and the adhesive removal member 122 so that the adhesive removal member 122 moves relative to the connecting seat 121 in a third direction Z. The elastic member 124 is disposed between the adhesive removal member 122 and the connecting seat 121.

[0102] The guide component 123 can refer to a component that serves a guiding function. The guide component 123 can refer to a guide rod guide hole structure, slide rail slider structure, slider groove structure, etc., provided in the connecting seat 121 and the adhesive removal component 122.

[0103] The elastic element 124 can refer to a component that can perform an elastic function. The elastic element 124 can be, but is not limited to, a spring, a sheet, an elastic rubber component, etc.

[0104] In the above technical solution, by providing a guide component 123 between the connecting seat 121 and the adhesive removal component 122, the reliability of the movement of the adhesive removal component 122 relative to the connecting seat 121 in the third direction Z can be improved, thereby enhancing the overall structural reliability of the adhesive removal assembly 12. By providing an independent elastic element 124, the way the adhesive removal component 122 achieves elastic movement in the third direction Z relative to the connecting seat 121 is relatively simple and reliable. In other words, the adhesive removal assembly 12, adopting the above structure, has a simple structure and good overall reliability, which is beneficial to improving the system stability of the assembly.

[0105] In some embodiments of this application, reference is made to Figure 5 The guide component 123 is a guide post. Except for the rubber part 122 and the connecting seat 121, one of them is provided with a guide hole, and the other is connected to the guide component 123. The guide component 123 passes through the guide hole. The elastic member 124 is cylindrical and is sleeved on the guide component 123.

[0106] In the above embodiments, the adhesive removal component 122 may be provided with a guide hole and the guide post may be provided on the connecting seat 121; or, the connecting seat 121 may be provided with a guide hole and the guide post may be provided on the adhesive removal component 122.

[0107] The elastic element 124 can be, but is not limited to, a spring, a rubber sleeve, etc. Optionally, the elastic element 124 can abut against the adhesive remover 122 and the connecting seat 121. In this example, regardless of whether the guide post is connected to the adhesive remover 122 or the connecting seat 121, the free end of the guide post can be provided with a limiting structure, such as a limiting block, to prevent the guide post from disengaging from the other component with the guide hole. Optionally, both ends of the elastic element 124 can also be connected to the adhesive remover 122 and the connecting seat 121 respectively. In this example, the free end of the guide post does not need to be provided with a limiting structure.

[0108] In the above technical solution, the guide component 123 and the elastic component 124 have simple structures and a low probability of failure, which is beneficial to improving the overall reliability of the adhesive removal assembly 12. Moreover, the simple structure of the guide component 123 and the elastic component 124 facilitates maintenance and repair, reduces operating costs, and is also convenient for manufacturing and assembly.

[0109] In some embodiments of this application, reference is made to Figure 2 , Figure 3 and Figure 4 The adhesive removal drive assembly 11 includes a fixed base 111 and a first drive member 112. The fixed base 111 is connected to the moving part 20. The first drive member 112 is disposed on the fixed base 111 and drives the adhesive removal assembly 12 to move and remove adhesive. The adhesive removal part 10 also includes a residual adhesive collection assembly 14, which is disposed on the fixed base 111 and located on the side of the adhesive removal assembly 12 away from the first drive member 112, for collecting the residual adhesive removed by the adhesive removal assembly 12.

[0110] The residual adhesive collection component 14 can refer to a component used to collect residual adhesive particles removed by the adhesive removal component 12. The phrase "the residual adhesive collection component 14 is located on the side of the adhesive removal component 12 away from the first drive member 112" can be understood as follows: when the adhesive removal component 12 removes adhesive along the first direction X, the first drive member 112 can be located on the rear side of the adhesive removal component 12, driving the adhesive removal component 12 to move forward to remove adhesive. Correspondingly, the residual adhesive collection component 14 can refer to a component located on the front side of the adhesive removal component 12, thereby collecting the cut-off residual adhesive particles as the adhesive removal component 12 moves forward to cut the residual adhesive.

[0111] In the above technical solution, by setting the residual adhesive collection component 14, the residual adhesive particles removed by the adhesive removal component 12 can be collected. On the one hand, this can reduce the probability of residual adhesive particles falling into the battery 200 and causing pollution, and also reduce the probability of residual adhesive particles falling into the surrounding environment and polluting the manufacturing workshop. On the other hand, it is also conducive to the recycling and reuse of residual adhesive particles, which can reduce the production cost of the battery 200.

[0112] In some embodiments of this application, reference is made to Figure 6 , Figure 7 and Figure 8The adhesive removal assembly 12 includes an adhesive removal component 122, which has a blade 122a for removing adhesive. The residual adhesive collection assembly 14 includes a collection container 141, a cover plate 142, and a second driving member. The collection container 141 has a top surface 141a, which is flush with the bottom surface 122b of the adhesive removal component 122 and has an opening. The cover plate 142 is placed over the opening. The second driving member is disposed on the collection container 141 and connected to the cover plate 142 to drive the cover plate 142 to open the opening.

[0113] The collection container 141 can refer to a container used to store residual adhesive particles. The collection container 141 can be, but is not limited to, a box, a cylinder, or a similar container. The collection container 141 can also be, but is not limited to, a cuboid, a cube, a semi-cylinder, or a cylinder. For example, see... Figure 3 and Figure 7 The collection container 141 is a rectangular collection chamber. The opening can refer to the open opening of the collection container 141, which is used for the entry and exit of residual adhesive particles.

[0114] Cover plate 142 can refer to a plate-like component used to cover and close an opening. The shape of cover plate 142 is adapted to the shape of the opening, and can be, but is not limited to, rectangular, square, circular, etc. For example, see reference... Figure 3 and Figure 4 The cover plate 142 is rectangular.

[0115] The second driving element can refer to a driving component that can drive the cover 142 to move to open or close the opening. The second driving element can be, but is not limited to, a pneumatic driving element, a hydraulic driving element, an electric driving element, and a magnetic driving element, etc. For example, the cover 142 is pivotally connected to the collection container 141, and the second driving element is a cylinder.

[0116] Reference Figure 8 The top surface 141a of the collection container 141 is flush with the bottom surface 122b of the adhesive removal component 122. When the adhesive removal component 122 moves along the first direction X, the blade 122a can cut off the residual adhesive of the battery cell 221. The cut-off residual adhesive can enter the opening of the top surface 141a of the collection container 141 under the action of the adhesive removal component 122, and thus enter the collection container 141.

[0117] In the above technical solution, by setting the residual adhesive collection component 14 into the above structure, the structure is relatively simple, easy to manufacture and process, and the cost can be reduced. By making the top surface 141a of the collection container 141 flush with the bottom surface 122b of the adhesive removal component 122, the residual adhesive particles that are easily cut can enter the collection container 141 more smoothly, reducing the travel distance of the residual adhesive particles into the collection container 141, thereby reducing the probability of residual adhesive particles falling outside the collection container 141 and improving the collection effect of residual adhesive particles.

[0118] In some embodiments of this application, reference is made to Figure 3 and Figure 4 The adhesive removal drive assembly 11 includes a limiting member 113, which is disposed on the fixed base 111 and has a limiting space for positioning the battery module 220. The residual adhesive collection assembly 14 is connected to the fixed base 111 through the limiting member 113.

[0119] The limiting member 113 can refer to a structural component used for positioning the battery module 220. The limiting member 113 can be, but is not limited to, a limiting plate, a limiting frame, etc. For example, refer to... Figure 3 The limiting member 113 is a U-shaped limiting frame set on the fixed base 111. When the battery module 220 is placed in the target position, the moving part 20 can drive the de-adhesive part 10 to move to the de-adhesive working position. At this time, the limiting space formed by the limiting member 113 can limit the battery module 220. For example, the limiting member 113 can at least limit the battery module 220 at both ends in the first direction X.

[0120] In the above technical solution, by setting the limiting member 113, the limiting space formed by the limiting member 113 can play the role of positioning and restricting the movement of the battery module 220, thereby reducing the probability of the battery module 220 moving when the adhesive removal component 12 removes adhesive and improving the reliability of adhesive removal.

[0121] Optionally, refer to Figure 3 and Figure 4 The limiting member 113 includes a limiting rod 1131 and a connecting rod 1132. The limiting rod 1131 is U-shaped and there are at least two of them, which are spaced apart along the second direction Y. The limiting rod 1131 is connected to the fixing seat 111, and the connecting rod 1132 extends along the second direction Y and is connected to the limiting rod 1131.

[0122] In the above embodiments, the multiple limiting rods 1131 and connecting rods 1132 can form a frame structure, which makes the limiting member 113 structurally strong and stable, and can extend its service life. Moreover, the limiting member 113 with the above structure is simple in structure, easy to process and manufacture, and can reduce costs.

[0123] In some embodiments of this application, the fixed base 111 is connected to the execution end of the moving part 20 via a force detection element 13. In this technical solution, the force detection element 13 can not only monitor the force transmitted from the adhesive removal component 12 to the adhesive removal drive component 11 in real time, but also monitor the force exerted by the moving part 20 on the adhesive removal drive component 11 in real time. The force detection path is relatively simple, and it is easier and more convenient to detect the force during the adhesive removal process, thereby improving the force detection effect.

[0124] In some embodiments of this application, reference is made to Figure 1 and Figure 9The movable part 20 includes a base 21 and a movable component 22. The movable component 22 is disposed on the base 21 and is configured to drive the adhesive removal part 10 to move along a first direction X, a second direction Y and a third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other. The adhesive removal drive assembly 11 drives the adhesive removal assembly 12 to move along the first direction X and remove adhesive.

[0125] The base 21 can refer to a component that provides support for the entire device. The base 21 can be, but is not limited to, a plate-shaped component, a frame structure component, etc. The base 21 can have a large contact surface with the ground, thereby providing more stable and reliable support for the moving part 20 as a whole, and improving the operational reliability of the entire adhesive removal device 100.

[0126] The moving component 22 can be understood as at least a three-axis moving mechanism. For example, the moving component 22 may include three moving mechanisms, which can respectively move in the first direction X, the second direction Y, and the third direction Z. The three moving mechanisms can be, but are not limited to, linear modules, etc.

[0127] In the above technical solution, the base 21 can provide better support for the moving part 22, improve the overall support stability of the moving part 20 on the ground, and by configuring the moving part 22 to drive the de-adhesion part 10 to move along the first direction X, the second direction Y and the third direction Z, the moving part 22 can perform multi-axis movement, with higher flexibility and adaptability, a wider range of movement and more precise adjustment capability, which is conducive to adjusting the de-adhesion part 10 to a de-adhesion working position suitable for de-adhesion of the battery module 220, and can adapt to de-adhesion operations in complex situations.

[0128] In some embodiments of this application, the first direction X and the second direction Y are parallel to the horizontal plane, and the force detection element 13 is configured to detect the force on the adhesive removal component 12 in the first direction X and the second direction Y at least in real time.

[0129] It can be understood that the force detection component 13 can detect the force on the adhesive removal component 12 in the first direction X and the second direction Y in real time, and can also monitor the force on the adhesive removal component 12 in the first direction X, the second direction Y and the third direction Z in real time.

[0130] In the above technical solution, the force detection component 13 is configured to detect the force on the adhesive removal component 12 in at least real time in the first direction X and the second direction Y. On the one hand, it can obtain the force information of the adhesive removal component 12 in the two main directions in the plane, so as to more comprehensively and accurately grasp the force state, which is conducive to ensuring the stable adhesive removal of the adhesive removal component 12. On the other hand, it can also accurately control and adjust the force applied by the adhesive removal component 12 during adhesive removal according to the force situation in at least two directions, thereby improving the reliability and accuracy of adhesive removal and improving the safety of operation.

[0131] In some embodiments of this application, reference is made to Figure 2 and Figure 9 The moving part 22 is a multi-degree-of-freedom robotic arm, and the end effector of the multi-degree-of-freedom robotic arm is connected to the glue removal drive assembly 11.

[0132] In the above technical solution, the multi-degree-of-freedom robotic arm can perform various complex actions in three-dimensional space, has high adjustment accuracy, and can perform more precise operations. This is beneficial for adapting to the position of the battery module 220 and adjusting the posture of the adhesive removal section 10, thereby successfully adjusting the adhesive removal section 10 to the adhesive removal working position. Moreover, the multi-degree-of-freedom robotic arm has good operational accuracy and force controllability, which can ensure the stability and consistency of multiple positioning of the adhesive removal section 10. It can also perform tasks quickly and continuously, which helps to reduce the work cycle and improve work efficiency.

[0133] In some embodiments of this application, reference is made to Figure 1 The movable parts 22 are provided in at least two, and each movable part 22 is connected to the adhesive removal part 10.

[0134] For example, multiple moving parts 22 may be arranged along the second direction Y, and each moving part 22 is connected to the adhesive removal part 10. Optionally, there may be two moving parts 22 and two adhesive removal parts 10. For battery modules 220 with larger dimensions in the second direction Y, multiple adhesive removal parts 10 can be set up to remove adhesive from the battery module 220 together, which is beneficial for removing adhesive from large-sized battery modules 220, improving adhesive removal efficiency, and saving manufacturing time of battery 200.

[0135] The adhesive removal device 100 for the battery module 220 provided according to the embodiments of this application includes: a robot workstation and an adhesive removal part.

[0136] The robot workstation includes a base 21 and a robot. The base 21 provides support and fixation. The robot is a multi-degree-of-freedom robot and is connected to a glue-removing part, which can move the glue-removing part to the work surface.

[0137] The glue scraping part includes a glue scraping drive assembly, a force control sensor, a glue scraping head assembly, and a residual glue collection assembly 14.

[0138] The glue-scraping drive assembly includes a fixed base 111, a valve island, and a cylinder. The fixed base 111 serves as a support frame and provides support and fixation for the valve island and cylinder. The fixed base 111 is connected to the end effector of the robot via a force control sensor. The valve island controls the movement of the cylinder, which provides reciprocating glue-scraping power to the glue-scraping head assembly. Multiple cylinders and glue-scraping head assemblies are configured in a one-to-one correspondence, with each cylinder driving its corresponding glue-scraping head assembly.

[0139] The glue scraper head assembly includes a connecting seat 121, a guide component 123, and a glue scraper head. The connecting seat 121 provides a fixed support for the guide component 123, and the guide component 123 provides elastic vertical movement space for the glue scraper head, which performs the function of scraping away glue particles.

[0140] The residual adhesive collection component 14 includes a collection chamber, an outer frame, and a top cover. The collection chamber mainly serves to collect and store adhesive particles, the outer frame mainly provides support and fixation for the collection chamber, and the top cover covers the opening of the collection chamber to prevent adhesive particles from spilling out.

[0141] When the adhesive removal device 100 removes adhesive, the robot first extends to the working position where the battery module 220 needs adhesive removal. The adhesive removal drive component moves to drive the adhesive removal head component to reciprocate and remove the residual adhesive from the battery module 220. The removed adhesive particles are collected by the residual adhesive collection component 14. During the adhesive removal process, the force control sensor monitors the torque data in the first direction X and the second direction Y in real time. When the monitored force control data exceeds the safe torque, an alarm is triggered and the machine stops.

[0142] It should be noted that, unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions. Unless otherwise stated, all technical features and optional technical features of this application can be combined to form new technical solutions.

[0143] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
