[0006] Summary of the Invention

[0007] In view of the above problems, the present application provides a disassembly and assembly device, which can automatically disassemble and assemble the valve assembly to be disassembled, thereby improving the disassembly and assembly efficiency of the valve assembly to be disassembled.

[0008] An embodiment of the present application provides a disassembly and assembly device, comprising a conveying assembly, a positioning assembly, and a disassembly and assembly assembly. The conveying assembly is configured to support and convey a battery cell with a valve assembly to be disassembled and assembled along a first direction. The positioning assembly is disposed on one side of the conveying assembly and is configured to locate the area of ​​the battery cell where the valve assembly is to be disassembled and assembled and obtain first positioning information. The disassembly and assembly assembly is located downstream of the positioning assembly along the first direction and is configured to move relative to the positioning assembly based on the first positioning information to disassemble and assemble the valve assembly.

[0009] The disassembly and assembly equipment provided in the embodiment of the present application can realize the disassembly and installation of the valve assembly to be disassembled and assembled on the battery cell through the coordinated arrangement of the conveying assembly, the positioning assembly, and the disassembly and assembly assembly, thereby saving human resources in the preparation process of the battery cell. In addition, the disassembly and assembly assembly can move relative to the positioning assembly according to the first positioning information, so that the disassembly and assembly valve assembly can improve the disassembly and assembly accuracy of the disassembly and assembly equipment, thereby improving the automation level and accuracy of the disassembly and assembly equipment, and improving the disassembly and assembly efficiency of the disassembly and assembly valve assembly of the battery cell.

[0010] In some embodiments, the disassembly assembly includes a valve core disassembly assembly, and the valve core disassembly assembly is configured to move relative to the conveying assembly according to the first positioning information to disassemble the valve core.

[0011] The disassembly and assembly equipment provided in the embodiment of the present application can disassemble or install the valve core through the provision of the valve core disassembly and assembly component, so that the disassembly and assembly equipment can disassemble and assemble the valve core, thereby improving the disassembly and assembly efficiency of the disassembly and assembly equipment on the valve core.

[0012] In some embodiments, the valve core disassembly assembly includes a first telescopic member and a disassembly member. The first telescopic member extends and is capable of retracting in a second direction, where the first direction intersects the second direction. The disassembly member is connected to the first telescopic member, and the first telescopic member is capable of driving the disassembly member to move in the second direction, thereby enabling the disassembly member to disassemble and assemble the valve core.

[0013] The disassembly and assembly equipment provided in the embodiment of the present application can realize the disassembly and installation of the valve core through the combination of the first telescopic part and the disassembly and assembly part. The connection between the disassembly and assembly part and the valve core and the plugging and unplugging of the valve core can be achieved through the extension and contraction of the first telescopic part. The operation is simple and can meet the disassembly and assembly requirements of the valve core. By driving the disassembly and assembly part to move along the second direction, the plugging and unplugging action is simple and practical, and the bending moment borne by the valve core is reduced. It can not only ensure the centering effect between the valve core and the injection hole during the plugging and unplugging process, but also reduce the probability of the valve core being damaged.

Since the disassembly and assembly parts are arranged in pairs, each disassembly and assembly part includes a connecting part and a limiting part, and the connecting part is connected to the connecting part and can drive the paired limiting parts to move toward or away from each other through the connecting part, which is conducive to the limiting part adapting to the shape of the valve core and ensuring the connection and separation between the limiting part and the valve core. When the valve core is disassembled and assembled, the disassembly and assembly efficiency and the stability of the connection between the limiting part and the valve core can be improved, and there is no need to puncture the valve core for disassembly and assembly, which can reduce the probability of structural damage to the valve core itself.

The disassembly assembly 300 of the disassembly device 10 can disassemble the valve assembly 21 to be disassembled.

[0051] The first positioning information acquired by the positioning assembly 200 includes the position information of the valve assembly 21 to be disassembled and the time information when the valve assembly 21 to be disassembled reaches the detection area of ​​the positioning assembly 200. The disassembly assembly 300 can adjust its position based on the position information, so that the disassembly assembly 300 can accurately locate the valve assembly 21 or the position where the valve assembly 21 is to be installed when disassembling or assembling the valve assembly 21. The disassembly assembly 300 can determine the time to disassemble or assemble the valve assembly 21 based on the time information and the speed at which the conveying assembly 100 conveys the battery cells 20.

[0052] The disassembly and assembly equipment 10 provided in the embodiment of the present application can realize the disassembly and installation of the valve assembly 21 to be disassembled and assembled on the battery cell 20 through the coordinated arrangement of the conveying component 100, the positioning component 200, and the disassembly and assembly component 300, thereby saving human resources in the preparation 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 as to improve the disassembly and assembly accuracy of the disassembly and assembly equipment 10, thereby improving the automation level and accuracy of the disassembly and assembly equipment 10, and improving the disassembly and assembly efficiency of the disassembly and assembly valve assembly 21 of the battery cell 20.

By driving the disassembly and assembly part 312 to move along the second direction Y, the plugging and unplugging action is simple and practical, and the bending moment borne by the valve core 211 is reduced, which can not only ensure the centering effect between the valve core 211 and the injection hole during the plugging and unplugging process, but also reduce the probability of the valve core 211 being damaged.

[0061] Please refer to FIG. 3 , which is a plan view of the disassembly and assembly parts in one embodiment of the disassembly and assembly device of the present application.

[0062] In some embodiments, the assembly and disassembly member 312 includes an assembly and disassembly portion 312a and a connecting portion 312b. The assembly and disassembly portions 312a are arranged in pairs, each comprising a connecting portion A1 and a limiting portion A2, with the connecting portion A1 connected to the limiting portion A2. The connecting portion 312b is located between the connecting portion A1 and the first telescopic member 311. The connecting portions 312b extend along the first direction X and are arranged in pairs. The connecting portions 312b are connected to the connecting portion A1 and can drive the paired limiting portions A2 to move toward or away from each other via the connecting portion A1.

[0063] The structures of the limiting portion A2 include an arc-shaped structure, a straight structure, etc. The limiting portion A2 can move toward or away from each other during operation to disassemble or assemble the valve core 211 .

[0064] The structure of the connecting portion 312b includes a V-shaped structure, and the two ends of the V-shaped structure can move toward or away from each other, thereby driving the paired limiting portions A2 to move toward or away from each other through the connecting portion A1. The V-shaped structure is slidingly connected to the first telescopic member 311 and can move relative to the first telescopic member 311 to drive the limiting portions A2 to move; the structure of the connecting portion 312b can also include paired vertical structures, and the paired vertical structures can move toward or away from each other, thereby driving the paired limiting portions A2 to move toward or away from each other through the connecting portion A1. For example, each vertical structure is connected to the first telescopic member 311 by a conveyor belt.

[0065] Illustratively, the limiting portion 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 portion A2 moves along the first direction X and away from the injection hole, allowing the valve core 211 to be removed. When the limiting portion A2 is a straight structure, the connecting portion A1 and the limiting portion A2 may form an L-shaped structure. The limiting portions A2 first move toward each other, allowing the limiting portions A2 to extend into the valve core 211. Thereafter, the limiting portions A2 are moved away from each other, allowing the limiting portions A2 to extend into the hole in the side wall of the valve core 211. Movement of the limiting portion A2 along the first direction X and toward the injection hole allows the valve core 211 to be installed in the injection hole.

[0066] In the disassembly and assembly device 10 provided in the embodiment of the present application, the disassembly and assembly member 312 includes a disassembly portion 312a and a connecting portion 312b, so that the disassembly portion 312a can be connected to the first telescopic member 311 via the connecting portion 312b to achieve position adjustment in the second direction Y. Since the disassembly and assembly members 312a are arranged in pairs, each disassembly and assembly member 312a includes a connecting portion A1 and a limiting portion A2, and the connecting portion 312b is connected to the connecting portion A1 and can drive the paired limiting portions A2 to move toward or away from each other through the connecting portion A1, the limiting portions A2 are adapted to the shape of the valve core 211, ensuring connection and separation with the valve core 211. When the valve core 211 is disassembled and assembled, the disassembly and assembly efficiency and the stability of the connection between the valve core 211 and the valve core 211 are improved. There is no need to pierce the valve core 211 for disassembly and assembly, which can reduce the probability of structural damage to the valve core 211 itself.

[0067] In some embodiments, the limiting portion A2 includes an arc-shaped structure and / or a straight structure.

[0068] The disassembly and assembly device 10 provided in the embodiment of the present application can replace the structure of the disassembly and assembly part 312a according to the actual usage scenario through the setting of the structure of the limiting part A2, so that the disassembly and assembly device 10 can be used in a wider range of scenarios.

[0069] In some embodiments, the disassembly and assembly assembly 300 also includes a valve sleeve installation assembly 320, which is located upstream of the valve core disassembly and assembly assembly 310. The valve sleeve installation assembly 320 is configured to move relative to the conveying assembly 100 according to the first positioning information and install the valve sleeve 212 into the injection hole of the battery cell 20.

[0070] The valve sleeve installation assembly 320 is electrically connected to the positioning assembly 200. The valve sleeve installation assembly 320 can adjust its own position according to the first positioning information, so that the valve sleeve installation assembly 320 can be accurately positioned at the injection hole when installing the valve sleeve 212. The valve sleeve installation assembly 320 can also determine its own installation time for the valve sleeve 212 based on the first positioning information and the speed at which the conveying assembly 100 conveys the battery cell 20.

[0071] The valve core disassembly and assembly component is electrically connected to the positioning component 200. The valve core disassembly and assembly component can adjust its own position according to the first positioning information, so that the valve core disassembly and assembly component 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 component can also determine its own disassembly and assembly time of the valve core based on the first positioning information and the speed at which the conveying component 100 conveys the battery cell 20.

[0072] The structure of the valve sleeve installation assembly 320 includes a vibration release member 321 or a drop structure, etc.

[0073] The disassembly and assembly device 10 provided in the embodiment of the present application, through the provision of the valve sleeve installation assembly 320 , can enable the disassembly and assembly device 10 to have the function of installing the valve sleeve 212 , and is more suitable for the installation of the valve assembly 21 of the injection hole of the battery cell 20 .

[0074] In some embodiments, the valve sleeve installation assembly 320 includes a vibration release member 321 and a holding assembly 322. The holding assembly 322 is arranged downstream of the vibration release member 321. The vibration release member 321 is configured to accommodate multiple valve sleeves 212 and insert one end of each valve sleeve 212 into the injection hole. The holding assembly 322 is configured to provide pressure to the valve sleeve 212 to continue to be inserted into the injection hole.

[0075] The pressing assembly 322 includes a pneumatic cylinder, a hydraulic cylinder, etc.

[0076] 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 exerted on the valve sleeve 212 (for example, the friction force exerted on the valve sleeve 212 by the shell 321a or the friction force exerted on the valve sleeve 212 by the piercing member B1), the valve sleeve 212 can fall to the liquid injection hole.

[0077] The disassembly and assembly equipment 10 provided in the embodiment of the present application includes a valve sleeve installation component 320 including a vibration release component 321 and a pressing component 322, so that the valve sleeve 212 is released to the injection hole through the vibration release component 321, and the valve sleeve 212 is pressed into the injection hole through the pressing component 322, thereby improving the installation efficiency of the valve sleeve 212.

[0078] In some embodiments, the vibration release member 321 includes a housing 321a and a vibration member 321b. The housing 321a defines a chamber, within which a penetration member B1 is disposed. The valve sleeve 212 can be inserted through the penetration member B1. The vibration member 321b is located within the chamber and penetrates the penetration member B1. The vibration member 321b is movable relative to the penetration member B1 to allow the valve sleeve 212 to fall into the injection hole.

[0079] The number of valve sleeves 212 passing through the penetrating member B1 can be one, two, or even more.

[0080] The vibration force of the vibration member 321 b on the valve sleeve 212 and the gravity of the valve sleeve 212 are greater than the friction force between the penetration member B1 and the valve sleeve 212 , so the valve sleeve 212 can fall into the liquid injection hole.

[0081] The vibration member 321b includes a vibration plate and a vibration motor. The vibration motor is connected to the penetration member B1 and can drive the vibration plate to vibrate.

[0082] The disassembly and assembly device 10 provided in the embodiment of the present application facilitates the valve sleeve 212 to fall into the liquid injection hole through the provision of the vibration release member 321, and has a simple design.

[0083] In some embodiments, the holding assembly 322 includes a hydraulic cylinder or a pneumatic cylinder.

[0084] The disassembly and assembly device 10 provided in the embodiment of the present application can press the valve sleeve 212 located at the injection hole through the setting of the pressing component 322, so that the valve sleeve 212 can be installed more tightly.

[0085] In some embodiments, the disassembly and assembly device 10 further includes a mounting seat 400 , and the valve sleeve mounting assembly 320 and the valve core 211 mounting assembly are respectively connected to the mounting seat 400 and have freedom of movement relative to the mounting seat 400 .
