[0002] Cleaning of the formation negative pressure components is an indispensable part of the battery manufacturing system. Regular cleaning of the negative pressure components can not only keep the formation equipment in a clean and efficient working state, reduce battery quality problems caused by electrolyte accumulation or backflow, but also ensure the health of operators.

[0003] However, the cleaning effect of the existing negative pressure component cleaning device is poor. Utility Model Content

[0004] The purpose of this application is to improve the cleaning effect of a negative pressure component cleaning device.

[0005] According to the present application, a negative pressure component cleaning device is provided, which is used to ultrasonically clean the negative pressure component in the battery formation equipment, including:

[0006] a cleaning tank configured to contain a negative pressure assembly and a cleaning fluid;

[0008] The cleaning liquid supply mechanism is configured to provide cleaning liquid to the cleaning tank. The cleaning liquid supply mechanism includes a solvent storage component and a cleaning agent storage component. The cleaning agent storage component can be selectively connected between the solvent storage component and the cleaning tank. In the connected state, the solvent provided by the solvent storage component and the cleaning agent provided by the cleaning agent storage component are mixed to form the cleaning liquid.

[0009] This embodiment can selectively provide cleaning agent through the cleaning agent storage component, and can increase or decrease the cleaning agent content in the cleaning liquid according to actual needs, thereby improving the cleaning effect; at the same time, the solvent storage component and the cleaning agent storage component are independently arranged, which can improve the convenience of operation and maintenance of the negative pressure component cleaning device.

[0010] In some embodiments, the solvent storage assembly includes a first storage component and a heating component, wherein the heating component is configured to heat the solvent in the first storage component.

[0013] This embodiment starts the heating component when the solvent in the first storage component reaches a first liquid level height, thereby ensuring that the solvent liquid level in the first storage component is always not less than the first liquid level height, avoiding dry burning of the heating component, improving the energy conversion rate of the heating component, and improving the safety of the negative pressure component cleaning device.

[0014] In some embodiments, a second liquid level sensor is provided in the first storage component, and the second liquid level sensor is configured to detect whether the liquid level of the solvent reaches a second liquid level, so as to stop replenishing the solvent to the first storage component when the solvent in the first storage component reaches the second liquid level, and the second liquid level is higher than the first liquid level.

[0015] This embodiment can avoid adding too much solvent into the first storage part by ensuring that the height of the solvent in the first storage part is not greater than the height of the second liquid level, and can also avoid insufficient heating of the solvent temperature due to excessive solvent, thereby avoiding a decrease in cleaning efficiency.

At the same time, by providing a positive-pressure hot air source, the negative pressure component does not need to be taken to a drying room separately, which can reduce residual water vapor in the negative pressure component.

The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0066] Battery formation refers to charging and discharging the battery under certain conditions after the battery is assembled, thereby activating the active substances on the battery electrode and generating a dense film on the anode surface to protect the entire chemical interface. The battery here refers to the battery monomer. At present, the cleaning of the formation negative pressure components wastes a lot of manpower and time. Because many people do not understand the importance and operation methods of cleaning the negative pressure components, the cleaning effect is poor and the cleaning efficiency is low.

[0070] The cleaning liquid supply mechanism 3 is configured to provide cleaning liquid to the cleaning tank 1. The cleaning liquid supply mechanism 3 includes a solvent storage component 31 and a cleaning agent storage component 32. The cleaning agent storage component 32 can be selectively connected between the solvent storage component 31 and the cleaning tank 1, and in the connected state, the solvent provided by the solvent storage component 31 and the cleaning agent provided by the cleaning agent storage component 32 are mixed to form the cleaning liquid.

[0071] Specifically, the cleaning agent storage component 32 is disposed downstream of the solvent storage assembly 31 and upstream of the cleaning tank 1. Specifically, the cleaning agent storage component 32 can selectively provide cleaning agent, that is, the cleaning agent storage component 32 provides cleaning agent in a connected state, and does not provide cleaning agent in a non-connected state.

[0072] Specifically, the ratio and frequency of use of the cleaning agent can be adjusted according to actual needs. For example, the cleaning agent can be added in the first few cycles of the cleaning liquid circulation cleaning to improve the cleaning effect, and the cleaning agent can be added in the last few cycles of the circulation cleaning to avoid residual cleaning agent impurities on the surface of the negative pressure component.

[0080] Optionally, a third filtering component 33 may be provided upstream of the first storage component 310 to filter the solvent entering the first storage component 310 to reduce impurities mixed in the cleaning liquid.

[0081] This embodiment can avoid adding too much solvent into the first storage part 310 by ensuring that the height of the solvent in the first storage part 310 is not greater than the second liquid level height, and can also avoid insufficient heating of the solvent temperature due to excessive solvent, thereby avoiding a decrease in cleaning efficiency.

[0096] Specifically, diaphragm pumps use compressed gas as a power source.

[0097] This embodiment provides a diaphragm pump 44 on the first pipeline 41 to extract and completely absorb the granular, high-viscosity, volatile and other impurity liquids in the circulating cleaning liquid, thereby improving the purity of the cleaning liquid and improving the cleaning effect of the negative pressure component cleaning device.

[0133] Combine the following Figure 1 A brief description of the working process of the cleaning device:

[0134] Before the cleaning device is started, all solenoid valves and manual valves are closed. After the cleaning device is started, the operator pre-sets the number of cycles through the user control interface 6 and manually opens all manual valves. The cleaning device automatically opens the first solenoid valve 101, and the solvent such as clean water enters the first storage component 310 after being filtered by the third filter component 33. After the first liquid level sensor 311 detects that the liquid level of the solvent reaches the first liquid level, the heating component 313 is started to heat the solvent. When the second liquid level sensor 312 detects that the liquid level of the solvent reaches the second liquid level, the first solenoid valve 101 is closed to stop adding solvent to the first storage component 310. After the temperature sensor 314 detects that the solvent temperature reaches the preset temperature, the second solenoid valve 102, the third solenoid valve 103, the sixth solenoid valve 106 and the diaphragm pump 44 are opened, and the third solenoid valve 103 is opened to mix the cleaning agent and the preheated solvent from the cleaning agent storage component 32 to form a cleaning liquid, and the cleaning liquid enters the cleaning tank 1 after passing through the node O, the diaphragm pump 44, the flow meter 45, and the manifold 12. After the fourth liquid level sensor 14 detects that the liquid level of the cleaning liquid reaches the fourth liquid level, the second solenoid valve 102, the third solenoid valve 103, the sixth solenoid valve 106 and the diaphragm pump 44 are closed, and the ultrasonic generating component 2 starts to ultrasonically clean the negative pressure component.

[0135] After one cleaning is completed, the fifth solenoid valve 105, the fourth solenoid valve 104 and the diaphragm pump 44 are opened, and the cleaning liquid enters the cleaning tank 1 again after passing through the first filter component 43, the node O, the diaphragm pump 44, the flow meter 45, and the manifold 12, and the next cleaning cycle is started. After reaching the preset number of cycles, the fourth solenoid valve 104 remains closed, the fifth solenoid valve 105 and the eighth solenoid valve 108 are opened, and the sewage reaches the second storage component 52. When the third liquid level sensor 53 detects that the liquid level of the sewage reaches the third liquid level, the indicator light 51 lights up to alarm, and the operator confirms direct discharge or discharge collection.

[0136] After all the sewage in the cleaning tank 1 is transferred to the second storage component 52, the fifth solenoid valve 105 and the eighth solenoid valve 108 are closed, the seventh solenoid valve 107 is opened, the positive pressure hot air source 8 introduces hot air into the cleaning tank 1 to dry the negative pressure component 100, the exhaust gas adsorption component 11 is opened, and the exhaust gas is filtered and discharged through the exhaust gas adsorption component 11, and the cleaning of the current negative pressure component 100 is completed.
