DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0026] Example 1

[0027] See also Figure 1 As shown, this embodiment provides a self-sealing adsorption device, which includes: a negative pressure component 200, the negative pressure component 200 includes a negative pressure pipe 210 and a plurality of negative pressure cups 220, the negative pressure pipe 210 is externally connected to a vacuum generating device, and is connected to the plurality of negative pressure cups 220; a plurality of suction nozzle assemblies 300, the plurality of suction nozzle assemblies 300 are connected to the plurality of negative pressure cups 220 in a one-to-one correspondence, and any of the suction nozzle assemblies 300 includes a self-sealing mechanism 320, the self-sealing mechanism 320 is connected to the negative pressure component 200 at both ends of the negative pressure cup 220 respectively, the self-sealing mechanism 320 is provided with an adsorption channel 324 connected to the liquid injection hole of the battery 400 and an elastic sealing nozzle 323 arranged in the adsorption channel 324, and the sealing nozzle is provided with a self-sealing opening.

[0028] The self-sealing adsorption device described in this practical embodiment is connected to multiple batteries 400 through multiple suction nozzle assemblies 300 in a one-to-one correspondence, and then the gas-liquid mixture inside the battery 400 is adsorbed through the negative pressure assembly 200, thereby assisting the volume separation process. During the above processing, the elastic sealing nozzle 323 inside the suction nozzle assembly 300 can connect the adsorption channel 324 with the internal environment of the battery 400 when there is gas flow, and automatically close the adsorption channel 324 when there is no gas flow. On the one hand, this improves the start-up and closing time of the equipment to improve the efficiency of a single operation. On the other hand, this type of structure is applicable to all battery 400 structures and can be applied to the synchronous adsorption process of multiple batteries 400, thereby giving it a wider range of use on the basis of doubling the processing time. Compared with conventional processing equipment at this stage, this application has significant advantages such as simple operation, short-term high efficiency, and strong universality, and has broad prospects for use in this industry.

[0029] See also Figure 1As shown, the self-sealing adsorption device in this embodiment can communicate without performing adsorption processing on multiple batteries 400, and further includes a mounting frame 100 in addition to the negative pressure component 200 and multiple suction nozzle assemblies 300. The negative pressure component 200 and the suction nozzle assembly 300 are respectively connected to the mounting frame 100. Furthermore, the mounting frame 100 in this embodiment can be fixed to an external mounting surface, and the negative pressure component 200 and the suction nozzle assembly 300 are respectively connected to the opposite sides of the bottom plate of the mounting frame 100.

[0030] See also Figure 1 and Figure 2 As shown, in this embodiment, the negative pressure pipeline 210 includes a main line 211 and a plurality of auxiliary lines 212. The plurality of auxiliary lines are respectively connected to the main line 211. The main line 211 is externally connected to a vacuum generating device, and the plurality of auxiliary lines 212 are respectively connected to the plurality of negative pressure cups 220. Furthermore, the main line 211 in this embodiment is connected to the mounting frame 100, and a connecting nozzle 213 is provided at one end thereof. The external vacuum generating device is connected to the main line 211 through the connecting nozzle 213. Specifically, the main line 211 is preferably a rigid vacuum element, and the auxiliary line is preferably a flexible rubber tube, thereby ensuring the stability of its installation and fixation while improving the flexibility of the layout between the individual structures.

[0031] The battery 400 and the corresponding suction nozzle assembly 300 in this embodiment have the same structural settings. Here, one of the groups is taken as an example for introduction: In this embodiment, the suction nozzle assembly 300 also includes a connecting assembly 310, and the self-sealing mechanism is connected to the mounting frame 100 through the connecting assembly 310. Specifically, the connecting assembly 310 in this embodiment includes a connecting block 311, a guide column 312 and a buffer 313. The connecting block 311 is connected to the mounting frame 100, the guide column 312 passes through the connecting block 311, and the buffer 313 is arranged around the guide column 312. Figure 3 The connecting assembly 310 and the self-sealing mechanism 320 shown are for reference only. The connecting block 311 is provided at the top of the connecting assembly 310 and is used to detachably connect to the lower surface of the mounting frame 100. The buffer 313 is preferably an elastic compression spring, which is sleeved around the outer periphery of the guide post 312. The guide post 312 and the elastic compression spring are both provided through the middle of the connecting block 311 and abut against the mounting frame 100. Thus, when the self-sealing mechanism 320 is connected to the battery 400 to adsorb the battery 400, the guide post 312 can guide the movement direction of the self-sealing mechanism 320, and the buffer 313 can buffer and limit the movement of the battery 400, thereby preventing collision and compression damage between the battery 400 and the connecting block 311 or the mounting frame 100. In different embodiments, the buffer 313 can also be configured as an elastic member with an automatic reset effect, such as an elastic sponge or elastic rubber, and the present invention does not impose specific restrictions on this.

[0032] See also Figure 4 As shown, the connecting assembly 310 further includes a nut 314 and a seal 315. The nut 314 is provided at one end of the self-sealing mechanism 320 away from the battery 400. The guide post 312 is passed through the nut 314 to be connected to the self-sealing mechanism 320. The seal 315 is provided at the connection between the guide post 312 and the nut 314. The nut 314 is used to achieve a fixed connection between the guide post 312 and the self-sealing mechanism 320. However, in actual use, there is a gas leakage problem at the connection gap between the nut 314 and the guide post 312, which in turn affects the effect of negative pressure adsorption. To overcome this problem, the present embodiment provides a seal 315 at the connection gap between the nut 314 and the guide post 312. Similarly, the present invention does not impose any specific restrictions on the specific type, material, and structure of the seal 315.

[0033] See also Figure 5 and Figure 6 As shown, the self-sealing mechanism 320 further includes a shell 321 and a nozzle core 322. The nozzle core 322 and the elastic sealing nozzle 323 are both connected to the interior of the shell 321. The adsorption channel 324 is disposed within the shell 321 and passes through the nozzle core 322 and the elastic sealing nozzle 323. The elastic sealing nozzle 323 is connected to the shell 321 via the nozzle core 322. When the self-sealing adsorption device is in a stationary state, the self-sealing opening is closed, and the elastic sealing nozzle 323 blocks the adsorption channel 324. When the self-sealing adsorption device is in an adsorption state, the self-sealing opening is opened, and the adsorption channel 324 is connected to the liquid filling port of the battery 400. Furthermore, the self-sealing opening in this embodiment is a cross-shaped incision. The adsorption force can drive airflow to break through the self-sealing opening, thereby causing it to open in the adsorption state. Correspondingly, when there is no force or airflow, the self-sealing opening can automatically close, thereby achieving a self-sealing effect. In this embodiment, the cross-shaped cutout not only increases the gas flow rate when it is opened, but also evenly distributes the force applied to each part, thereby reducing elastic fatigue and thereby improving the sealing effect and service life. The present invention does not limit the specific shape of the self-sealing opening.

[0034] Further, see Figure 6As shown, in this embodiment, the lower portion of the housing 321 is provided with an abutment surface, the nozzle core 322 is snap-fitted onto the abutment surface, and the elastic sealing nozzle 323 is connected to the center of the nozzle core 322. In the direction of gas flow, the abutment surface divides the adsorption channel 324 into two parts, wherein the cross-sectional area of ​​the adsorption channel 324 on the side close to the battery 400 is smaller than the cross-sectional area of ​​the adsorption channel 324 on the side close to the negative pressure component 200. This design can concentrate the adsorption force at the liquid injection port of the battery 400 while increasing the adsorption gas flow rate, thereby achieving the optimal adsorption effect. In addition, it also has the effect of preventing the adsorption channel 324 from being blocked.

[0035] Example 2

[0036] This embodiment provides a battery 400 processing device, which includes the self-sealing adsorption device described in the first embodiment.

[0037] In summary, the self-sealing adsorption equipment and battery 400 processing device described in the present invention connect multiple batteries 400 one by one through multiple suction nozzle assemblies 300, and then adsorb the gas-liquid mixture inside the battery 400 through the negative pressure assembly 200, thereby assisting the volume separation process. During the above processing, the elastic sealing nozzle 323 inside the suction nozzle assembly 300 can connect the adsorption channel 324 with the internal environment of the battery 400 when there is gas flow, and automatically close the adsorption channel 324 when there is no gas flow. On the one hand, this improves the start-up and closing time of the equipment to improve the efficiency of a single operation. On the other hand, this type of structure can be applied to all battery 400 structures, and can be applied to the synchronous adsorption process of multiple batteries 400, thereby giving it a wider range of use on the basis of doubling the processing time. Compared with conventional processing equipment at this stage, the present application has significant advantages such as simple operation, short-time high efficiency, and strong universality, and has broad prospects for use in this industry.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
