[0069] The disassembling and assembling device 10 provided by the embodiment of the present application can realize the disassembly and installation of the valve core 211 through the combined setting of the first telescopic member 311 and the disassembling and assembling member 312. Through the telescopic movement of the first telescopic member 311, the connection between the disassembling and assembling member 312 and the valve core 211 and the insertion and extraction of the valve core 211 can be realized. The operation is simple and can meet the disassembly and assembly requirements of the valve core 211. By driving the disassembling and assembling member 312 to move along the second direction Y, the insertion and extraction action is simple, with strong practicability, and the bending moment borne by the valve core 211 is reduced. It can not only ensure the centering effect with the liquid injection hole during the insertion and extraction process, but also reduce the probability of damage to the valve core 211.

[0070] Please refer to Figure 3 as shown in Figure 3 is a schematic plan view of the disassembling and assembling member in an embodiment of the disassembling and assembling device of the present application.

[0071] In some embodiments, the disassembling and assembling member 312 includes a disassembling and assembling part 312a and a connecting part 312b.

[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, so as to drive 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 part A2 to move; the structure of the connecting part 312b can also include a pair of vertical structures. The pair of vertical structures can move towards or away from each other, so as to drive 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 through a conveyor belt.

[0074] Exemplarily, the limiting part A2 can include a pair of arc-shaped structures.

The limiting part A2 moves along the first direction X and away from the liquid injection hole, which can disassemble the valve core 211. 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, and the limiting part A2 can extend into the valve core 211. Then, the limiting part A2 is made to move away from each other, and the limiting part A2 can extend into the hole in the side wall of the valve core 211. Making the limiting part A2 move along the first direction X and close to the liquid injection hole can install the valve core 211 on the liquid injection hole.

Since the disassembly and assembly parts 312a are arranged in pairs, each disassembly and assembly part 312a includes the connecting part A1 and the 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 towards or away from each other through the connecting part A1, which is beneficial to the limiting part A2 to adapt to the shape of the valve core 211, ensure the connection and separation with the valve core 211, improve the disassembly and assembly efficiency and the connection stability with the valve core 211 when disassembling and assembling the valve core 211, and 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.

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

[0077] The disassembly and assembly device 10 provided by the embodiment of the present application can replace the structure of the disassembly and assembly part 312a according to the actual use scenario through the setting of the structure of the limiting part A2, so that the disassembly and assembly device 10 has a wider range of use scenarios.

The valve sleeve installation component 320 is located upstream of the valve core disassembly and assembly component 310. The valve sleeve installation component 320 is configured to move relative to the conveying component 100 according to the first positioning information and install the valve sleeve 212 into the liquid injection hole of the battery cell 20.

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

[0080] 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 be accurately positioned 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 the disassembly and assembly time of the valve core according to the first positioning information and the conveying speed of the battery cell 20 by the conveying component 100.

[0081] The structure of the valve sleeve installation component 320 includes a vibration release member 321 or a falling structure, etc.

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

[0083] In some embodiments, the valve sleeve installation component 320 includes a vibration release member 321 and a pressing component 322. The pressing component 322 is arranged 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 liquid injection hole. The pressing component 322 is configured to provide a pressure for the valve sleeve 212 to continue to be inserted into the liquid injection hole.

[0084] The pressing component 322 includes a pneumatic cylinder, a hydraulic cylinder, etc.

[0085] The vibration direction of the vibration release member 321 intersects with the first direction X. When the falling force of the valve sleeve 212 is greater than the upward force received by the valve sleeve 212 (for example, the frictional force of the valve sleeve 212 against the housing 321a or the frictional force of the valve sleeve 212 against the penetrating member B1), the valve sleeve 212 can fall into the liquid injection hole.

[0086] For the disassembly and assembly device 10 provided in the embodiments of the present application, through the arrangement of the valve sleeve installation assembly 320 including the vibration release member 321 and the pressing assembly 322, the valve sleeve 212 is released into the liquid injection hole through the vibration release member 321, and the valve sleeve 212 is pressed into the liquid injection hole through the pressing assembly 322, 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 penetrating member B1 is arranged inside the chamber. The valve sleeve 212 can penetrate through the penetrating member B1. The vibration member 321b is located in the chamber, penetrates through the penetrating member B1 and can move relative to the penetrating member B1 to make the valve sleeve 212 fall into the liquid injection hole.

[0088] The number of valve sleeves 212 penetrating through the penetrating member B1 can be one, two, or even multiple, etc.

[0089] The vibration force of the vibration member 321b on the valve sleeve 212 and the gravity of the valve sleeve 212 are greater than the friction force between the penetrating member B1 and the valve sleeve 212, and the valve sleeve 212 can fall to the liquid injection hole.

[0090] The vibration member 321b includes a vibration plate and a vibration motor. The vibration motor is connected to the penetrating member B1 and can drive the vibration plate to vibrate.
