[0001] This application relates to the field of battery auxiliary equipment, and in particular to a disassembly and assembly device for disassembling and assembling valve assemblies in battery cells. Background Technology

[0002] The battery cell is provided with an injection hole, through which electrolyte is injected into the battery cell. A valve assembly is provided at the injection hole location to open or seal the injection hole. During the battery cell manufacturing process, the valve assembly needs to be disassembled and assembled.

[0003] In related technologies, the disassembly and assembly of valve assemblies are often done manually, which wastes human resources and is inefficient. Summary of the Invention

[0004] In view of the above problems, this application provides a disassembly and assembly device that can automatically disassemble and assemble valve assemblies to be disassembled and assembled, thereby improving the disassembly and assembly efficiency of valve assemblies to be disassembled and assembled.

[0005] This application provides a disassembly / removal device, which includes a conveying component, a positioning component, and a disassembly / removal component. The conveying component is configured to support and convey a battery cell with a valve assembly to be disassembled / removed along a first direction. The positioning component is disposed on one side of the conveying component and is configured to locate the area of ​​the battery cell with the valve assembly to be disassembled / removed and acquire first positioning information. The disassembly / removal component is located downstream of the positioning component along the first direction and is configured to move relative to the positioning component according to the first positioning information to disassemble / remove the valve assembly.

[0006] The disassembly and assembly equipment provided in this application, through the coordinated arrangement of the conveying component, the positioning component, and the disassembly and assembly component, can disassemble and install the valve assembly to be disassembled and installed on the battery cell, saving human resources in the battery cell manufacturing process. In addition, the disassembly and assembly component can move relative to the positioning component according to the first positioning information, so that the valve assembly can be disassembled and installed, thereby improving the disassembly and assembly accuracy of the disassembly and assembly equipment, improving the automation level and accuracy of the disassembly and assembly equipment, and improving the disassembly and assembly efficiency of the valve assembly of the battery cell.

[0007] In some embodiments, the disassembly assembly includes a valve core disassembly assembly configured to move relative to the transport assembly according to first positioning information to disassemble or assemble the valve core.

[0008] The disassembly and assembly equipment provided in this application embodiment, through the setting of valve core disassembly and assembly components, can disassemble or install the valve core, thereby improving the disassembly and assembly efficiency of the disassembly and assembly equipment for valve core.

[0009] In some embodiments, the valve core disassembly and assembly includes a first telescopic member and a disassembly and assembly member. The first telescopic member extends and is telescopic in a second direction, and the first direction intersects the second direction. The disassembly and assembly member is connected to the first telescopic member, and the first telescopic member can drive the disassembly and assembly member to move in the second direction, enabling the disassembly and assembly member to disassemble and assemble the valve core.

[0010] The disassembly and assembly device provided in this application embodiment, through the combination of the first telescopic component and the disassembly and assembly component, can realize the disassembly and assembly of the valve core. The extension and retraction of the first telescopic component can realize the connection between the disassembly and assembly component and the valve core, as well as the insertion and removal of the valve core. The operation is simple and can ensure the disassembly and assembly requirements of the valve core. By driving the disassembly and assembly component to move along the second direction, the insertion and removal action is simple, practical, and reduces the bending moment borne by the valve core. It can ensure the alignment effect between the valve core and the injection hole during the insertion and removal process, and reduce the probability of damage to the valve core.

[0011] In some embodiments, the detachable component includes a detachable part and a connecting part. The detachable parts are arranged in pairs, and each detachable part includes a connecting part and a limiting part, with the connecting part connected to the limiting part. The connecting part is located between the connecting part and the first telescopic member, extends along a first direction and is arranged in pairs, and is connected to the connecting part and can drive the paired limiting parts to move closer to or further away from each other through the connecting part.

[0012] The disassembly and assembly device provided in this application embodiment, by including a disassembly and assembly part and a connecting part in the disassembly and assembly component, enables the disassembly and assembly part to connect with the first telescopic member via the connecting part, thereby achieving position adjustment in the second direction. Since the disassembly and assembly parts are arranged in pairs, each disassembly and assembly part includes a connecting part and a limiting part. The connecting part connects with the connecting part and can drive the paired limiting parts to move closer to or further away from each other through the connecting part. This facilitates the limiting part adapting to the shape of the valve core, ensuring connection and separation with the valve core. When disassembling and assembling the valve core, this improves disassembly and assembly efficiency and the stability of the connection with the valve core during disassembly and assembly. Furthermore, it eliminates the need to pierce the valve core during disassembly and assembly, reducing the probability of structural damage to the valve core itself.

[0013] In some embodiments, the limiting portion includes an arcuate structure and / or a straight structure.

[0016] The disassembly and assembly equipment provided in this application embodiment, through the setting of the valve sleeve mounting assembly, enables the disassembly and assembly equipment to have the function of installing valve sleeves, which is more suitable for the installation of valve assemblies for the liquid injection holes of battery cells.

[0017] In some embodiments, the valve sleeve mounting assembly includes a vibration release member and a holding member, the holding member being disposed downstream of the vibration release member, the vibration release member being configured to receive a plurality of valve sleeves and insert one end of each valve sleeve into an injection port, and the holding member being configured to provide pressure to the valve sleeve for further insertion into the injection port.

[0018] The disassembly and assembly equipment provided in this application, through the configuration of the valve sleeve installation assembly including a vibration release component and a pressing component, allows the valve sleeve to be released from the injection hole via the vibration release component and pressed into the injection hole via the pressing component, thereby improving the installation efficiency of the valve sleeve.

[0019] In some embodiments, the vibration release element includes a housing and a vibrating element. The housing has a chamber with a through-hole inside, through which a valve sleeve can pass. The vibrating element is located in the chamber, passes through the through-hole, and is movable relative to the through-hole, causing the valve sleeve to fall into the injection hole.

[0020] The disassembly and assembly device provided in this application embodiment facilitates the valve sleeve to fall into the injection hole through the setting of the vibration release component, and the design is simple.

[0021] In some embodiments, the holding assembly includes at least one of a telescopic cylinder and a cam structure.

[0022] The disassembly and assembly device provided in this application adopts the above-described form through the pressing component, which has a simple structure, is easy to control, and can ensure accurate control of the insertion position of the valve sleeve in the injection hole. In some embodiments, the disassembly and assembly device further includes a mounting base, and the valve sleeve mounting assembly and the valve core mounting assembly are respectively connected to the mounting base and have a degree of freedom of movement relative to the mounting base.

[0053] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0054] A battery cell typically includes an electrode assembly. The electrode assembly includes a positive electrode and a negative electrode. During the charging and discharging process of the battery cell, active ions (such as lithium ions) repeatedly insert and extract between the positive and negative electrodes. The positive electrode can be a positive electrode sheet, which may include a positive electrode current collector and a layer of positive electrode active material disposed on at least one surface of the positive electrode current collector. The battery cell includes an injection port through which liquid can be injected, and the injection port is often equipped with a valve assembly to prevent liquid leakage or contamination of the internal liquid of the battery cell.

[0055] In the manufacturing process of battery cells, valve assemblies often need to be disassembled and assembled. However, in related technologies, the disassembly and assembly of valve assemblies are often done manually, which wastes human resources and is inefficient.

[0056] To address the aforementioned issues, research has revealed that a disassembly and assembly device can be provided to automatically disassemble and assemble the valve assembly to be disassembled, thereby reducing the proportion of manual intervention and improving the efficiency of disassembly and assembly of the valve assembly.

[0057] Please refer to Figure 1 , 2 As shown, Figure 1 This is a schematic diagram of the structure of one embodiment of the disassembly and assembly equipment of this application. Figure 2 This is a schematic diagram of another embodiment of the disassembly and assembly equipment of this application.

[0058] This application provides a disassembly / reassembly device 10, which includes a conveying assembly 100, a positioning assembly 200, and a disassembly / reassembly assembly 300. The conveying assembly 100 is configured to support and convey a battery cell 20 with a valve assembly 21 to be disassembled / reassembled along a first direction X. The positioning assembly 200 is disposed on one side of the conveying assembly 100 and is configured to position the area of ​​the battery cell 20 with the valve assembly 21 to be disassembled / reassembled and acquire first positioning information. The disassembly / reassembly assembly 300 is located downstream of the positioning assembly 200 along the first direction X and is configured to move relative to the positioning assembly 200 according to the first positioning information to disassemble / reassemble the valve assembly 21.

[0059] Optionally, the valve assembly 21 to be disassembled includes a valve sleeve 212 and a valve core 211. The valve sleeve 212 may be made of a soft material, such as rubber or silicone, while the valve core 211 may be made of plastic or metal. The valve sleeve 212 has a ring-shaped structure, and the valve core 211 can be nested inside the valve sleeve 212. The valve core 211 and the valve sleeve 212 are used in conjunction. The disassembly and assembly component 300 of the disassembly and assembly device 10 can disassemble and assemble the valve assembly 21 to be disassembled.

[0060] The first positioning information acquired by the positioning component 200 includes the position information of the valve assembly 21 to be disassembled / assembled and the time information of the valve assembly 21 arriving at the detection area of ​​the positioning component 200. The disassembly / assembly component 300 can adjust its own position according to the position information, so that the disassembly / assembly component 300 can accurately position itself on the valve assembly 21 or the position where the valve assembly 21 needs to be installed when disassembling / assembling the valve assembly 21. The disassembly / assembly component 300 can determine the time for disassembling / assembling the valve assembly 21 according to the time information and the speed of the conveying battery cell 20 of the conveying component 100.

[0061] The disassembly and assembly equipment 10 provided in this application embodiment, through the coordinated arrangement of the conveying component 100, the positioning component 200, and the disassembly and assembly component 300, can disassemble and install the valve assembly 21 to be disassembled and installed on the battery cell 20, saving human resources in the manufacturing process of the battery cell 20. In addition, the disassembly and assembly component 300 can move relative to the positioning component 200 according to the first positioning information, so that the valve assembly 21 can be disassembled and installed, thereby improving the disassembly and assembly accuracy of the disassembly and assembly equipment 10, improving the automation level and accuracy of the disassembly and assembly equipment 10, and improving the disassembly and assembly efficiency of the valve assembly 21 of the battery cell 20.

[0062] In some embodiments, the disassembly assembly 300 includes a valve core disassembly assembly 310, which is configured to move relative to the transport assembly 100 according to first positioning information to disassemble or assemble the valve core 211.

[0063] The valve core 211 may be made of metal or other materials. Optionally, the valve core 211 may have multiple perforated structures.

[0064] The disassembly and assembly device 10 provided in this application embodiment can disassemble or install the valve core 211 by setting the valve core disassembly and assembly component 310, so that the disassembly and assembly device 10 can disassemble and assemble the valve core 211, thereby improving the disassembly and assembly efficiency of the disassembly and assembly device 10 on the valve core 211.

[0065] In some embodiments, the valve core disassembly and assembly 310 includes a first telescopic member 311 and a disassembly and assembly member 312. The first telescopic member 311 extends along a second direction Y and is capable of telescoping along the second direction Y, where the first direction X intersects with the second direction Y. The disassembly and assembly member 312 is connected to the first telescopic member 311, and the first telescopic member 311 can drive the disassembly and assembly member 312 to move along the second direction Y, enabling the disassembly and assembly member 312 to disassemble and assemble the valve core 211.

[0066] The angle between the first direction X and the second direction Y includes 80 degrees, 90 degrees, 100 degrees, etc., and optionally, the angle between the two is 90 degrees.

[0067] The first telescopic component 311 includes at least one of the following structures: a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0068] The assembly / disassembly component 312 includes arc-shaped structures, straight structures, etc., to ensure a proper fit with the valve core.

[0069] The disassembly and assembly device 10 provided in this application embodiment, through the combination of the first telescopic member 311 and the disassembly and assembly member 312, can realize the disassembly and assembly of the valve core 211. The extension and retraction of the first telescopic member 311 can realize the connection between the disassembly and assembly member 312 and the valve core 211, as well as the insertion and removal of the valve core 211. The operation is simple and can ensure the disassembly and assembly requirements of the valve core 211. By driving the disassembly and assembly member 312 to move along the second direction Y, the insertion and removal action is simple, practical, and reduces the bending moment borne by the valve core 211. It can ensure the alignment effect between the valve core 211 and the injection hole during the insertion and removal process, and reduce the probability of damage to the valve core 211.

[0070] Please refer to Figure 3 As shown, Figure 3 This is a plan view of the disassembly and assembly components in one embodiment of the disassembly and assembly equipment of this application.

[0071] In some embodiments, the disassembly / assembly component 312 includes a disassembly / assembly part 312a and a connecting part 312b. The disassembly / assembly parts 312a are arranged in pairs, and each disassembly / assembly part 312a includes a connecting part A1 and a limiting part A2, with the connecting part A1 connected to the limiting part A2. The connecting part 312b is located between the connecting part A1 and the first telescopic member 311, and the connecting part 312b extends along a first direction X and is arranged in pairs. The connecting part 312b is connected to the connecting part A1 and can drive the paired limiting parts A2 to move closer to or further away from each other through the connecting part A1.

[0072] The limiting part A2 has a structure including an arc-shaped structure and a straight structure. During operation, the limiting part A2 can move towards or away from each other to disassemble and assemble the valve core 211.

[0073] The structure of the connecting part 312b includes a V-shaped structure. The two ends of the V-shaped structure can move towards or away from each other, thereby driving the paired limiting parts A2 to move towards or away from each other through the connecting part A1. The V-shaped structure is slidably connected to the first telescopic member 311 and can move relative to the first telescopic member 311 to drive the limiting parts A2 to move. The structure of the connecting part 312b may also include a pair of vertical structures. The paired vertical structures can move towards or away from each other, thereby driving the paired limiting parts A2 to move towards or away from each other through the connecting part A1. For example, each vertical structure is connected to the first telescopic member 311 by a conveyor belt.

[0074] For example, the limiting part A2 may include a pair of arc-shaped structures. When the two are close together, at least a portion of the outer wall of the valve core 211 matches the shape of the adjacent arc-shaped structure. The limiting part A2 can be disassembled by moving along the first direction X and away from the injection hole. When the limiting part A2 is a straight structure, the connecting part A1 and the limiting part A2 can form an L-shaped structure. The limiting part A2 first moves towards each other, allowing it to extend into the valve core 211. Then, the limiting part A2 moves away from each other, allowing it to extend into the hole in the side wall of the valve core 211. The movement of the limiting part A2 along the first direction X and close to the injection hole allows the valve core 211 to be installed in the injection hole.

[0075] The disassembly and assembly device 10 provided in this application embodiment, through the arrangement of the disassembly and assembly component 312 including a disassembly and assembly part 312a and a connecting part 312b, enables the disassembly and assembly part 312a to be connected to the first telescopic member 311 via the connecting part 312b, thereby realizing position adjustment in the second direction Y. Since the disassembly and assembly parts 312a are arranged in pairs, each disassembly and assembly part 312a includes a connecting part A1 and a limiting part A2, and the connecting part 312b is connected to the connecting part A1 and can drive the paired limiting parts A2 to move closer to or further away from each other through the connecting part A1, which is beneficial for the limiting part A2 to adapt to the shape of the valve core 211, ensuring the connection and separation between the limiting part A2 and the valve core 211. When disassembling and assembling the valve core 211, the disassembly and assembly efficiency and the stability of the connection between the limiting part A2 and the valve core 211 can be improved, and the valve core 211 does not need to be pierced for disassembly and assembly, which can reduce the probability of structural damage to the valve core 211 itself.

[0076] In some embodiments, the limiting portion A2 includes an arc-shaped structure and / or a straight structure.

[0077] The disassembly and assembly device 10 provided in this application embodiment can change the structure of the disassembly and assembly part 312a according to the actual usage scenario by setting the structure of the limiting part A2, so that the disassembly and assembly device 10 can be used in a wider range of scenarios.

[0078] In some embodiments, the disassembly assembly 300 further includes a valve sleeve mounting assembly 320, which is located upstream of the valve core disassembly assembly 310. The valve sleeve mounting assembly 320 is configured to move relative to the delivery assembly 100 according to first positioning information and to install the valve sleeve 212 into the injection hole of the battery cell 20.

[0079] The valve sleeve mounting assembly 320 is electrically connected to the positioning assembly 200. The valve sleeve mounting assembly 320 can adjust its own position according to the first positioning information, so that the valve sleeve mounting assembly 320 can be accurately positioned at the injection hole when installing the valve sleeve 212. The valve sleeve mounting assembly 320 can also determine its own installation time for the valve sleeve 212 according to the first positioning information and the speed at which the conveying assembly 100 conveys the battery cell 20.

[0080] The valve core disassembly and assembly assembly is electrically connected to the positioning assembly 200. The valve core disassembly and assembly assembly can adjust its own position according to the first positioning information, so that the valve core disassembly and assembly assembly can accurately position itself at the valve core disassembly and assembly position when disassembling and assembling the valve core. The valve core disassembly and assembly assembly assembly can also determine its own disassembly and assembly time for the valve core according to the first positioning information and the speed at which the conveying assembly 100 conveys the battery cell 20.

[0081] The structure of the valve sleeve mounting assembly 320 includes a vibration release element 321 or a drop structure, etc.

[0082] The disassembly and assembly device 10 provided in this application embodiment, through the setting of the valve sleeve mounting assembly 320, enables the disassembly and assembly device 10 to have the function of installing the valve sleeve 212, which is more suitable for the installation of the valve assembly 21 of the liquid injection hole of the battery cell 20.

[0083] In some embodiments, the valve sleeve mounting assembly 320 includes a vibration release member 321 and a pressure holding member 322. The pressure holding member 322 is disposed downstream of the vibration release member 321. The vibration release member 321 is configured to accommodate a plurality of valve sleeves 212 and insert one end of each valve sleeve 212 into the injection port. The pressure holding member 322 is configured to provide pressure to the valve sleeve 212 to continue inserting into the injection port.

[0084] The holding assembly 322 includes pneumatic cylinders, hydraulic cylinders, etc.

[0085] When the vibration direction of the vibration release member 321 intersects with the first direction X, and the falling force of the valve sleeve 212 is greater than the upward force on the valve sleeve 212 (e.g., the friction force of the valve sleeve 212 on the housing 321a or the friction force of the valve sleeve 212 on the through member B1), the valve sleeve 212 can fall to the injection hole.

[0086] The disassembly and assembly device 10 provided in this application embodiment, through the valve sleeve installation assembly 320 including the vibration release member 321 and the pressing assembly 322, allows the valve sleeve 212 to be released from the injection hole through the vibration release member 321 and the valve sleeve 212 to be pressed into the injection hole through the pressing assembly 322, thereby improving the installation efficiency of the valve sleeve 212.

[0087] In some embodiments, the vibration release member 321 includes a housing 321a and a vibration member 321b. The housing 321a has a chamber, and a through member B1 is provided inside the chamber, through which the valve sleeve 212 can pass. The vibration member 321b is located in the chamber, passes through the through member B1, and is movable relative to the through member B1, allowing the valve sleeve 212 to fall into the injection hole.

[0088] The number of valve sleeves 212 that pass through the through-piece B1 can be one, two, or even more.

[0089] The vibration force of the vibrating element 321b on the valve sleeve 212 and the weight of the valve sleeve 212 are greater than the frictional force between the through-piece B1 and the valve sleeve 212, so the valve sleeve 212 can fall into the injection hole.

[0090] The vibrating element 321b includes a vibrating plate and a vibrating motor. The vibrating motor is connected to the through-piece B1 and can drive the vibrating plate to vibrate.

[0091] The disassembly and assembly device 10 provided in this application embodiment facilitates the valve sleeve 212 to fall into the injection hole through the setting of the vibration release component 321, and the design is simple.

[0092] In some embodiments, the holding assembly 322 includes a hydraulic cylinder or a pneumatic cylinder.

[0093] The disassembly and assembly device 10 provided in this application embodiment can press the valve sleeve 212 located at the injection hole by setting the pressing component 322, so that the valve sleeve 212 is installed more tightly.

[0094] In some embodiments, the disassembly and assembly device 10 further includes a mounting base 400, a valve sleeve mounting assembly 320 and a valve core 211 mounting assembly, which are respectively connected to the mounting base 400 and have a degree of freedom of movement relative to the mounting base 400.

[0095] Mounting base 400 includes plate structure, frame structure, etc.

[0096] The valve sleeve mounting assembly 320 and the valve core 211 mounting assembly can move relative to the mounting base 400 in multiple directions. Optionally, the mounting base 400 has multiple slide rails in different directions on the side facing the mounting assembly 300. The valve sleeve mounting assembly 320 and the valve core 211 mounting assembly are connected to the mounting base 400 through the slide rails.

[0097] The disassembly and assembly device 10 provided in this application embodiment facilitates the installation of the valve sleeve mounting assembly 320 and the valve core 211 mounting assembly through the setting of the mounting base 400, thereby improving the integration level of the disassembly and assembly device 10.

[0098] In some embodiments, the positioning component 200 includes at least one of a laser locator or an image acquisition component.
