[0040] In order to understand the embodiments of the present application more clearly, the following Figures 1 to 8 The embodiments of the present application are described in detail.

[0041] like Figures 1 to 8 As shown, the present application provides a liquid removal device 1 for removing electrolyte from the inner wall of a housing 2. The liquid removal device 1 includes a blowing assembly 11, a liquid removal assembly 12, and a driving mechanism 13. The liquid removal assembly 11 includes a guide 121 and an abutment 122 sleeved on the guide 121. One end of the abutment 121 abuts against the housing 2. A flow channel 123 leading to the housing 2 is formed between the inner wall of the abutment 121 and the outer wall of the guide 122. The flow channel 123 is connected to the liquid removal assembly 11 to blow air into the housing 2. The driving mechanism 13 is connected to the liquid removal assembly 12 and / or the housing 2 to drive the liquid removal assembly 12 and the housing 2 to move away from or approach each other.

[0042] The housing 2 may be cylindrical or square, and this is not limited in the present embodiment. Figure 8 As shown, in order to limit the position of the battery cell assembly 3 in the shell 2, a shoulder 22 recessed into the shell 2 is provided on the shell 2. When the electrolyte is injected into the shell 2, electrolyte is likely to remain on the shoulder 22, and the electrolyte on the shoulder 22 cannot automatically flow back to the lower part of the shell 2 under the action of gravity. Therefore, the liquid removal device 1 of the present application is provided to blow gas into the shell 2, thereby blowing the electrolyte remaining on the shoulder 22 into the shell 2 to prevent the electrolyte from affecting subsequent processing.

[0043] The blowing assembly 11 is a device that can provide gas to the liquid removal assembly 12. The gas provided by the blowing assembly 11 can be air or an inert gas such as helium. For example, in some embodiments, the blowing assembly 11 provides nitrogen to the liquid removal assembly 11 to blow off the electrolyte on the inner wall of the housing 2.

[0044] The abutment member 122 is sleeved onto the guide member 121. Specifically, a through-hole is provided on the abutment member 122, and the guide member 121 is partially inserted into the through-hole of the abutment member 122. Furthermore, a flow passage 123 leading to the housing 2 is formed between the inner wall of the abutment member 121 and the outer wall of the guide member 122. Specifically, in some embodiments, a recess is provided on either the inner wall of the abutment member 121 or the outer wall of the guide member 122 to form the flow passage 123. In other embodiments, recesses are provided on both the inner wall of the abutment member 121 and the outer wall of the guide member 122 to form the flow passage 123. By sleeve-mounting the abutment 122 on the guide member 121 and setting the circulation channel 123 between the inner wall of the abutment 121 and the outer wall of the guide member 122, it is convenient to manufacture the corresponding circulation channel 123 on the inner wall of the abutment 121 and / or the outer wall of the guide member 122 during the production process, thereby facilitating the production of the liquid removal device 1.

[0045] The cross-sectional shape of the circulation channel 123 can be a regular shape such as a circle or a rectangle, or an irregular shape, and this is not limited in the present embodiment. The circulation channel 123 can be composed of multiple channels evenly distributed on the inner wall of the abutment member 121 and the outer wall of the guide member 122. The multiple channels are evenly distributed along the shape of the housing 2 to ensure that all areas within the housing 2 can be blown with gas. In addition, the circulation channel 123 can also be composed of channels that completely surround the inner wall of the abutment member 121 and the outer wall of the guide member 121, thereby increasing the coverage of the gas blown into the housing 2.

[0046] One end of the abutment 121 abuts against the shell 2, that is, when removing the liquid, the open end of the shell 2 abuts against the end face of the abutment 121 close to the shell 2. In this way, the flow channel 123 can be located on the inner side of the shell 2, and the gas blown out from the flow channel 123 can enter the shell, ensuring that the electrolyte can be blown off smoothly.

[0047] The driving mechanism 13 is a component capable of providing driving force. Specifically, the driving mechanism 13 may be a cam mechanism, or may be a motor, a hydraulic cylinder, an electric cylinder, or other mechanism, and the embodiments of the present application are not limited thereto. Specifically, in some embodiments, the driving mechanism 13 is drivingly connected to either the liquid removal assembly 12 or the housing 2 to drive the liquid removal assembly 12 and the housing 2 away from or toward each other; in other embodiments, the driving mechanism 13 is drivingly connected to both the liquid removal assembly 12 and the housing 2 to increase the driving speed and thus improve the production efficiency of the liquid removal device 1.

[0048] By setting up the liquid removal component 12, a circulation channel 123 leading to the shell 2 is formed between the inner wall of the abutment 122 and the outer wall of the guide member 121. When the blowing component 11 provides gas, the gas can be blown into the shell 2 along the circulation channel 123, thereby blowing off the electrolyte remaining on the inner wall of the shell 2, improving the sealing of the shell 2 in the subsequent sealing process and the durability of the production tools, thereby improving the production quality of the battery.

[0049] like Figure 8 As shown, in some embodiments, the inner wall of the abutting member 122 is recessed inwardly to form an annular circulation channel 123 ; and / or the outer wall of the guiding member 121 is recessed inwardly to form an annular circulation channel 123 .

[0050] By providing the annular circulation channel 123 , during the liquid removal process, the gas can flow along the annular circulation channel 123 to cover all areas inside the housing 2 , thereby improving the electrolyte removal effect.

[0051] like Figure 8 As shown, in some embodiments, the circulation channel 123 includes at least a first circulation channel 1231 and a second circulation channel 1232 that are connected to each other, the first circulation channel 1231 is connected to the blowing assembly 11, and the second circulation channel 1232 is connected to the shell 2, and the first circulation channel 1231 is larger than the second circulation channel 1232 to form a step portion 1233 between the first circulation channel 1231 and the second circulation channel 1232.

[0052] The first circulation channel 1231 is connected to the blowing assembly 11 , and the second circulation channel 1232 is connected to the shell 2 . That is, the gas blown out from the blowing assembly 11 flows through the first circulation channel 1231 and the second circulation channel 1232 in sequence before reaching the shell 2 .

[0053] By setting the first circulation channel 131 and the second circulation channel 132 and the first circulation channel 1231 being larger than the second circulation channel 1232, a step portion 1233 can be formed between the first circulation channel 1231 and the second circulation channel 1232. Due to the existence of the step portion 1233, after the gas enters the first circulation channel 1231, it will fill the entire first circulation channel 1231 under the obstruction of the step portion 1233, and then enter the second circulation channel 1232. In this way, the uniformity of the gas in the second circulation channel 1232 can be ensured. On the one hand, it can prevent the uneven blowing of gas, which may cause no gas to be blown out in some areas of the shell 2 or the blowing gas intensity to be insufficient and unable to effectively remove the electrolyte. On the other hand, the uniform gas can also ensure that the shell 2 is subjected to uniform gas driving force in all directions during the deliquidation process, ensuring that the shell 2 is stably fixed in the fixture.

[0054] It should be noted that the circulation channel 123 may also be composed of a plurality of circulation channels of different sizes to further improve the uniformity of the gas blown into the housing 2 .

[0055] like Figure 2 、 7 As shown in Figures 8 and 8, in some embodiments, the shape of the circulation channel 123 is the same as the shape of the shell 2, the geometric center of the circulation channel 123 coincides with the geometric center of the shell 2, and the size of the air outlet of the circulation channel 123 close to the shell 2 is less than or equal to the size of the inner wall of the shell 2.

[0056] The shape of the circulation channel 123 is the same as that of the shell 2, that is, the circulation channel 123 is an annular circulation channel with the same shape as the shell 2. Furthermore, the geometric center of the circulation channel 123 coincides with the geometric center of the shell 2, that is, the shape enclosed by the air outlet of the circulation channel 123 is consistent with the shape of the shell 2, thereby ensuring that all positions in the shell 2 can be blown by the gas from the blowing assembly 11, thereby ensuring the effective removal of all electrolyte in the shell 2.

[0057] When the size of the outlet of the circulation channel 123 near the housing 2 is larger than the size of the inner wall of the housing 2, the gas blown out of the circulation channel 123 will partially blow onto the end of the housing 2 near the abutment 122, hindering the smooth flow of air into the housing 2. This will change the direction of the airflow and weaken the intensity of the airflow blowing onto the inner wall of the housing 2, thereby reducing the electrolyte removal effect. In addition, when the size of the outlet of the circulation channel 123 near the housing 2 is too large, or even larger than the size of the outer wall of the housing 2, some gas will flow out through the gap between the circulation channel 123 and the outer wall of the housing 2, also weakening the electrolyte removal effect.

[0058] Therefore, by setting the size of the air outlet of the circulation channel 123 close to the shell 2 to be smaller than or equal to the size of the inner wall of the shell 2, it can be ensured that the gas in the circulation channel 123 can be effectively blown into the shell, ensuring the liquid removal effect of the liquid removal device 1.

[0059] like Figure 8 As shown, in some embodiments, the guide member 121 protrudes from the abutment member 122 and partially extends into the housing 2 .

[0060] The guide member 121 is protruded from the abutment member 122, and the length of the flow channel 123 can be extended through the channel formed between the part of the guide member 121 extending into the shell 2 and the inner wall of the shell 2, which can increase the depth and intensity of the gas flowing into the shell 2, and further improve the effect of the liquid removal device 1 in removing the electrolyte.

[0061] like Figure 8As shown, in some embodiments, a chamfer is provided on the inner wall of the abutting member 122 close to the housing 2 ; and / or a chamfer is provided on the outer wall of the guiding member 121 close to the housing 2 .

[0062] That is, in some embodiments, a chamfer is provided on the inner wall of the abutment 122 close to the shell 2 or the outer wall of the guide member 121 close to the shell 2; while in other embodiments, a chamfer is provided on both the inner wall of the abutment 122 close to the shell 2 and the outer wall of the guide member 121 close to the shell 2.

[0063] By setting a chamfer, the cross-sectional area of ​​the circulation channel 123 at this position can be increased, so that the direction of the blown gas can be changed, and the area swept by the gas when it is blown out from the circulation channel 123 is increased, ensuring that the electrolyte at the opening of the shell 2 can also be blown off and removed.

[0064] like Figures 4 to 7 As shown, in some embodiments, the liquid removal device 1 also includes a connecting component 14, the connecting component 14 includes a mounting member 141 and an elastic member 142, the end of the liquid removal component 14 facing away from the shell 2 is connected to the mounting member 141, and the elastic member 142 is arranged between the mounting member 141 and the liquid removal component 12.

[0065] The elastic member 142 can be an elastic component such as rubber, or a spring, and this embodiment of the present application does not limit this. Specifically, one end of the elastic member 142 can be fixed to the mounting member 141, and the other end can be fixed to the liquid removal assembly 12, thereby providing a buoyancy force for the liquid removal assembly 12; or a recessed portion can be provided on the surface where the mounting member 141 and the liquid removal assembly 12 are close to each other, and the elastic member 142 can be accommodated in the recessed portion to fix the elastic member 142 between the mounting member 141 and the liquid removal assembly 12. At this time, it should be noted that the depth of the recessed portion should be less than the length of the elastic member 142 to ensure that the elastic member 142 can be squeezed to provide a buoyancy force for the liquid removal assembly 12.

[0066] By setting the elastic member 142, when the shell 2 abuts against the abutment member 122, on the one hand, the elastic member 142 can be compressed to prevent the shell 2 and the abutment member 122 from being damaged due to rigid contact. On the other hand, the compressed elastic member 142 can also ensure effective abutment between the shell 2 and the abutment member 122 through elastic force to prevent gas leakage between the two.

[0067] like Figures 4 to 7 As shown, in some embodiments, the connecting component 14 also includes a guide rod 143, one end of the guide rod 142 is movably mounted on the mounting member 141, and the other end is connected to the liquid removal component 12, the elastic member 142 is mounted on one end of the guide rod 143 close to the liquid removal component 12, and one end of the elastic member 142 is in contact with the mounting member 141, and the other end is in contact with the guide rod 143.

[0068] The connection between the other end of the guide rod 142 and the liquid removal assembly 12 can be connected in a detachable manner such as bolt connection or disassembly, or can be connected in a non-detachable manner such as welding or gluing, and the embodiment of the present application does not limit this.

[0069] In some embodiments, the other end of the elastic member 142 is fixedly connected to the guide rod 143 to ensure that the elastic member 142 can be compressed or stretched when the guide rod 143 and the mounting member 14 move relative to each other; in other embodiments, a boss can be provided on the outer periphery of the guide rod 143, and the other end of the elastic member 142 can be abutted against the boss, so as to realize the compression or stretching of the elastic member 142 when the guide rod 143 and the mounting member 141 move relative to each other.

[0070] By setting a guide rod 143 and sleeve the elastic member 142 on the guide rod 143, the movement direction of the elastic member 142 can be limited to ensure that it can only be compressed or extended along its own extension direction, preventing it from detaching from between the mounting member 141 and the liquid removal assembly 12.

[0071] like Figure 1 、 4 As shown in Figure 6, in some embodiments, the liquid removal device 1 further includes a sensing component 15, the sensing component 15 includes a sensor 151 and a sensor 152 arranged at intervals along the first direction X, the sensor 151 is arranged at one end of the guide rod 143 away from the liquid removal component 12, and the sensor 152 is arranged on the mounting member 141. When the sensor 152 detects the sensor 151, the driving mechanism 13 stops driving.

[0072] A sensor 151 and a sensor 152 are respectively provided on the end of the guide rod 143 facing away from the liquid removal component 12 and on the mounting member 141. When the shell 2 abuts against the abutment 122, the guide rod 143 will move along the first direction relative to the mounting member 141, so that the sensor 151 gradually approaches the sensor 152. When the sensor 151 and the sensor 152 are located on the same horizontal plane, the sensor 152 detects the sensor 151, thereby controlling the driving mechanism 13 to stop driving, that is, the shell 2 and the abutment 122 have abutted in place, so that the abutment force between the shell 2 and the abutment 122 is avoided from being too large and damaging both.

[0073] like Figure 7 and Figure 8 As shown, in some embodiments, the liquid removal device 1 further includes an exhaust assembly (not shown in the figure), the guide member 121 and the guide rod 143 are hollow structures, and the exhaust assembly is connected to the guide member 121 and / or the guide rod 143.

[0074] The exhaust component is a component that discharges the gas in the liquid removal device 1. Specifically, in some embodiments, the exhaust component can be an exhaust channel to discharge the gas in the shell 2 to the outside of the shell 2; in other embodiments, the exhaust component can also be a negative pressure device, which generates a negative pressure to extract the gas out of the liquid removal device 1. On the one hand, it can increase the flow rate of the gas in the shell 2 and increase the liquid removal effect. On the other hand, the generated negative pressure can also extract the excess electrolyte in the shell 2.

[0075] Providing the guide member 121 and the guide rod 143 with a hollow structure can, on the one hand, save material and reduce the weight of the liquid removal device 1, and on the other hand, can arrange an exhaust component to exhaust the gas in the liquid removal device 1. In addition, in some embodiments, the battery cell assembly 3 is further provided with a tab 31. By providing the guide member 121 with a hollow structure, the tab 31 can be avoided when the abutting member 122 and the housing 2 abut, preventing the tab 31 from interfering with the guide member 121.

[0076] By arranging an exhaust assembly to discharge the gas in the liquid removal device 2, a gas passage can be formed between the liquid removal device 1 and the shell 2, and while discharging the gas, excess electrolyte can also be taken away.

[0077] like Figure 1 and Figure 3 As shown, in some embodiments, the liquid removal device 1 further includes a frame 16 , a mounting member 141 is movably disposed on the frame 16 along a first direction X, and the driving mechanism 13 is drivingly connected to the mounting member 141 to drive the liquid removal assembly 12 toward or away from the shell 2 .

[0078] The frame 16 refers to a component that remains relatively stationary with respect to the ground. By connecting the mounting member 141 to the frame 16 , it is convenient to control the movement of the mounting member 141 , thereby achieving control over the relative position between the liquid removal assembly 12 and the housing 2 .

[0079] The mounting member 141 is movably arranged on the frame 16 along the first direction X. Specifically, the movement of the mounting member 141 relative to the frame 16 can be achieved by a guide rail slider mechanism, or by a gear rack mechanism or a screw mechanism. The embodiment of the present application does not limit this.

[0080] The drive mechanism 13 is a component that provides power for the movement of the mounting member 141 relative to the frame 16. Specifically, the drive mechanism 13 can be a motor, or an electric cylinder, an air cylinder, a hydraulic cylinder, a cam, etc. For example, when the movement of the mounting member 141 relative to the frame 16 is achieved through a guide rail slider mechanism, the drive mechanism 13 can be an electric cylinder, an air cylinder, a hydraulic cylinder, etc., and the linear motion output by the drive mechanism 13 is used to push the mounting member 141 relative to the frame 16. When the movement of the mounting member 141 relative to the frame 16 is achieved through a rack and pinion mechanism, the drive mechanism 13 can be a motor, etc., and the rack and pinion mechanism converts the rotational motion output by the drive mechanism 13 into linear motion to push the mounting member 141 relative to the frame 16. In addition, the drive mechanism 13 can also be set as a cam mechanism, which converts the rotational motion of the motor into linear motion to push the mounting member 141 relative to the frame 16.

[0081] like Figure 1 As shown, in some embodiments, a guide rail 161 extending along the first direction X is provided on the rack 16 , and a slider 1411 is provided on the mounting member 141 , and the slider 1411 is movably provided on the guide rail 161 .

[0082] That is, the movement of the mounting member 141 relative to the frame 16 is achieved by the movement of the slider 1411 on the guide rail 161 .

[0083] Specifically, such as Figures 1 to 8 As shown, before liquid removal, the shell 2 and the liquid removal component 12 are spaced apart.

[0084] During liquid removal, the drive mechanism 13 drives the mounting member 141 to move relative to the frame 16, thereby causing the liquid removal assembly 12 to gradually approach the shell 2. Subsequently, the shell 2 abuts against the abutment member 122 and pushes the guide rod 143 to compress the elastic member 142, causing the guide rod 143 to move relative to the mounting member 141, further driving the sensor 151 on the guide rod 143 to gradually approach the sensor 152. When the sensor 152 detects the sensor 151, it indicates that the elastic member 142 has been compressed to a preset position, which can provide sufficient elastic force for the abutment between the abutment member 122 and the shell 2. At this time, the drive mechanism 13 stops operating. Finally, the blowing assembly 11 and the exhaust assembly are opened to form an airflow in the circulation channel 123 and the shell 2, thereby blowing off or taking out the electrolyte attached to the inner side of the shell 2, thereby removing the electrolyte in the shell 2.

[0085] After the liquid removal is completed, the blowing assembly 11 and the exhaust assembly stop running, and the driving mechanism 13 drives the mounting member 141 to move away from the shell 2, so that the abutment member 122 and the shell are separated, which facilitates the unloading of the shell 2 for liquid removal and the loading of the shell 2 to be liquid removed, and the next liquid removal process is carried out.

[0086] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
