[0059] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0060] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0061] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0062] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0063] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0064] like Figures 1 to 11As shown, according to one aspect of the utility model, there is provided a cleaning device for a negative pressure assembly for battery formation, comprising: a cleaning tool 1 and a liquid injection and discharge device 2, the liquid injection and discharge device 2 being connectable to a power source; the cleaning tool 1 comprising a plurality of buffer cup mechanisms 11, the liquid injection and discharge device 2 comprising a connecting component, the connecting component being connectable to a cleaning liquid storage component 4 and a waste liquid storage component 5, the cleaning tool 1 having a first position and a second position relative to the liquid injection and discharge device 2; when the cleaning tool 1 is located at the first position, the buffer cup mechanism 11 is connectable to the connecting component, so that the power source can drive the cleaning liquid in the cleaning liquid storage component 4 to flow into the buffer cup mechanism 11, or drive the waste liquid in the buffer cup mechanism 11 to flow into the waste liquid storage component 5; when the cleaning tool 1 is located at the second position, the plurality of buffer cup mechanisms 11 are connectable to the negative pressure assembly.

[0065] Specifically, in this embodiment, the cleaning device of the negative pressure component includes two parts: a cleaning tool 1 and a liquid injection and discharge device 2. The cleaning tool 1 is used to clean the negative pressure component (usually a negative pressure cup) used in the battery formation process, and the liquid injection and discharge device 2 is used to perform liquid injection operations on the buffer cup mechanism 11 before cleaning, so that the buffer cup mechanism 11 can store cleaning liquid, and to perform liquid discharge operations on the buffer cup mechanism 11 after cleaning, so that the cleaning liquid after cleaning can be discharged from the buffer cup mechanism 11. The liquid injection and discharge operations of the buffer cup mechanism 11 and the cleaning process of the negative pressure component can be achieved by connecting the liquid injection and discharge device 2 to a power source, and connecting the cleaning tool 1 to a power source, and the choice of the power source can be flexibly selected according to actual needs, without being restricted by the limitation of small occupied space.

[0066] For example, when the buffer cup mechanism 11 is filled or drained, the cleaning tool 1 can be moved to the first position so that the buffer cup mechanism 11 can be connected to the connecting component, thereby realizing the filling of the buffer cup mechanism 11 through the cleaning liquid storage component 4, or the drainage of the buffer cup mechanism 11 through the waste liquid storage component 5. Among them, the movement of the cleaning tool 1 can be achieved by equipment such as a stacker, and the utility model does not limit this. In addition, after the filling or draining process is completed, the cleaning tool 1 can be disconnected from the connecting component to perform the operation of cleaning the negative pressure component or other processes.

[0067] In the above-mentioned process of filling and draining liquid, the cleaning tool 1 is not limited by the space occupied by the negative pressure components and other equipment, and a power source device with a larger power can be selected. For example, the liquid filling and draining device 2 can be connected to the air pressure power source of the factory to improve the efficiency of liquid filling and draining liquid. Or in the process of cleaning the negative pressure cup, there is no restriction on the space occupied by the liquid filling and draining device 2, and the cleaning tool 1 or the negative pressure cup can be connected to the air pressure power source of the factory to improve the efficiency of cleaning the negative pressure cup.

[0068] Furthermore, in the above device, the specific forms of the buffer cup mechanism 11, the negative pressure assembly and the connection assembly can be selected and designed according to actual needs. Among them, the connection assembly can be designed as a channel pressing mechanism 25, and correspondingly, the buffer cup mechanism 11 is also designed with a nozzle pressing mechanism 15 that matches the channel pressing mechanism 25. Alternatively, a connecting valve or a manifold block can also be selected at the same time, and the utility model does not limit this.

[0069] Alternatively, if Figures 2 to 4 As shown, multiple cache cup mechanisms 11 are divided into n groups, each group forms a cache cup cleaning assembly, and the cleaning tool 1 also includes an overflow chamber assembly 12 and n overflow pipes 13; each cache cup cleaning assembly is connected to the overflow chamber assembly 12 through an overflow pipe 13, and the overflow chamber assembly 12 is also connected to the waste liquid storage assembly 5.

[0070] Specifically, in the present embodiment, the cache cup mechanism 11 is provided with n groups, each group becomes an integrated cache cup cleaning assembly, and is respectively connected to the overflow chamber assembly 12 through an overflow pipe 13, so that during the filling process, if the cleaning liquid in each cache cup mechanism 11 is filled, it can be converged into the overflow chamber assembly 12 through the corresponding overflow pipe 13, and the overflow chamber assembly 12 is connected to the waste liquid storage assembly 5, so that the overflowed cleaning liquid can be finally recovered into the waste liquid storage assembly 5 to avoid its overflow and polluting the environment.

[0071] In practical applications, in order to improve the cleaning efficiency, the number of cache cup mechanisms 11 is usually designed to be larger, and when it is connected to the connection assembly, in order to improve the efficiency of liquid injection or liquid discharge, it is necessary to open more cache cup mechanisms 11 than in the cleaning process at the same time. The number of interfaces of the connection assembly can be designed to be larger than the number of cache cup mechanisms 11 in a group of cache cup cleaning assemblies. Therefore, n can be set to an even number greater than 0 to facilitate the design of the connection assembly. For example, in one embodiment, 4 groups of cache cup cleaning assemblies can be set, and each group of cache cup 111 assemblies includes 8 cache cup mechanisms 11, then two groups of connection assemblies can be set, and each group is designed to match the number of interfaces of the cache cup mechanism 11 with 16, so as to improve the efficiency of liquid injection and liquid discharge.

[0072] In the above embodiments, by separately designing the cleaning tool 1 and the liquid injection and discharge equipment 2 and grouping the multiple buffer cup mechanisms 11, a high degree of modularization of the cleaning tool 1 is achieved, making the internal piping of the entire device relatively simple and facilitating subsequent maintenance work.

[0073] In actual application, the cleaning tool 1 can also include a tool frame and n fixed brackets. Each cache cup cleaning assembly is detachably assembled on the tool frame through a fixed bracket. When maintenance is required, only the fixed bracket needs to be removed from the tool frame for easy maintenance and cleaning.

[0074] Alternatively, if Figure 1 to Figure 2 As shown, it also includes a control device 3, which can control the operation of the cleaning tool 1 and the liquid injection and discharge device 2; the cleaning tool 1 also includes n control components 14, and the n control components 14 are all connected to the control device 3, and a control component 14 is respectively arranged between each overflow pipe 13 and the overflow chamber assembly 12 to control the opening and closing of the overflow pipe 13.

[0075] Specifically, in this embodiment, the control device 3 can be connected to the cleaning tool 1 and the liquid injection and discharge device 2 at the same time to control the operation of the two. For example, the liquid injection and discharge device 2 is controlled to perform the liquid injection or discharge process, and the cleaning tool 1 is controlled to perform the process of cleaning the negative pressure component, or the cleaning tool 1 is controlled to be connected to the liquid injection and discharge device 2, so that the entire device can achieve an automated mode, further improving the cleaning efficiency.

[0076] In one embodiment, based on the miniaturization requirement of the cleaning tool 1, an electrical control part can also be provided in the cleaning tool 1, and the liquid injection and discharge equipment 2 can be designed with a separate electrical control cabinet and a bracket for carrying the connecting components, etc., so as to automatically control the automatic docking of the cache cup mechanism 11 and the connecting components.

[0077] In the above device, a control component 14 is respectively provided between each overflow pipe 13 and the overflow chamber assembly 12, and the control components 14 are all connected to the control device 3, and the control components 14 can be opened or closed to control the on-off of the overflow pipe 13. And each control component 14 is in a normally closed state, so that the air tightness test of the cleaning tool 1 can be carried out before cleaning the negative pressure component to prevent air leakage. And when performing the cleaning work, a control component 14 can be opened, so that when using, for example, a negative pressure power source for cleaning work, only one group of buffer cup cleaning components can be cleaned to reduce the problem of poor cleaning effect caused by uneven air pressure. After a group of negative pressure cups is cleaned, the corresponding control component 14 is closed, and the other control component 14 is opened, so that the other group of buffer cup cleaning components continues to clean the next group of negative pressure cups, which can be performed n times in sequence.

[0078] Alternatively, if Figures 2 to 3As shown, each overflow pipe 13 includes a plurality of overflow branch pipes 131 and an overflow main pipe 132, the number of the overflow branch pipes 131 is equal to the number of the cache cup mechanisms 11 included in each cache cup cleaning assembly, a plurality of overflow branch pipe interfaces 1321 and a control component interface 1322 are provided on the overflow main pipe 132, and the upper end of each cache cup mechanism 11 has an overflow port 115; one end of each overflow branch pipe 131 is connected to an overflow port 115, and the other end is connected to an overflow branch pipe interface 1321, and the control component 14 is connected to the control component interface 1322; the height of the overflow port 115 is higher than the height of the overflow branch pipe interface 1321, and the height of the overflow branch pipe interface 1321 is higher than the height of the control component interface 1322.

[0079] Specifically, in this embodiment, during the liquid filling process, if the cleaning liquid in each buffer cup mechanism 11 is filled, it can be merged into the overflow main pipe 132 through the overflow branch pipe 131, that is, when the cleaning liquid in each group of buffer cup mechanisms 11 (a buffer cup cleaning assembly) is filled, it can be merged into the overflow chamber assembly 12 through the overflow pipe 13. Among them, the height of the overflow port 115, the overflow branch pipe interface 1321 and the control valve interface is limited, so that when the cleaning liquid in the buffer cup mechanism 11 is full, it can flow into the overflow chamber assembly 12 through the overflow pipe 13 based on the action of gravity, without the need for driving the power source, saving energy and manpower operation costs.

[0080] The number of overflow branches 131 included in each overflow pipe 13 is equal to the number of cache cup mechanisms 11 included in each set of cache cup cleaning components, so that each cache cup mechanism 11 can be connected to the overflow main pipe 132 through an overflow branch pipe 131, and then flow into the overflow chamber assembly 12 through the overflow main pipe 132. The overflow port 115 is arranged at the upper end of the cache cup mechanism 11, usually near the upper part of the cache cup 111. In this embodiment, as long as it is higher than the height of the overflow branch pipe interface 1321 and the control component interface 1322, refer to Figure 3 .

[0081] Alternatively, if Figures 2 to 4 As shown, the cache cup cleaning assembly also includes a plurality of nozzle pressing mechanisms 15, and the number of the nozzle pressing mechanisms 15 is equal to the number of the cache cup mechanisms 11; the connecting assembly includes a confluence structure and a plurality of channel pressing mechanisms 25 connected to the confluence structure, and the number of the channel pressing mechanisms 25 is equal to the number of the nozzle pressing mechanisms 15; the channel pressing mechanisms 25 can be press-connected with the nozzle pressing mechanisms 15 in a one-to-one correspondence, and the plurality of channel pressing mechanisms 25 can be respectively connected to the cleaning liquid storage assembly 4 and the waste liquid storage assembly 5 through the confluence structure.

[0082] Specifically, in this embodiment, the multiple suction nozzle pressing mechanisms 15 provided in the buffer cup 111 assembly can be pressed against the multiple channel pressing mechanisms 25 in a one-to-one correspondence, so that when the cleaning tool 1 is located at the first position to fill and discharge liquid or discharge waste liquid, the cleaning liquid can flow smoothly into the buffer cup mechanism 11, or the waste liquid can flow from the buffer cup mechanism 11 into the waste liquid storage assembly 5. The buffer cup 111 assembly is connected to the connection assembly through the pressing of the suction nozzle pressing mechanism 15 and the channel pressing structure, which facilitates the docking connection between the buffer cup mechanism 11 and the connection assembly on the one hand, and the suction nozzle pressing mechanism 15 and the channel pressing mechanism 25 have better sealing after pressing, so that the cleaning liquid is not easy to volatilize to the outside, ensuring the safety performance of the equipment.

[0083] In addition, the confluence structure can select structures such as confluence tubes or confluence blocks, and can be flexibly selected according to actual needs. For example, in one embodiment, 4 groups of cache cup cleaning components are provided, and each group of cache cup 111 components includes 8 cache cup mechanisms 11, that is, each group of cache cup mechanisms 11 has 8 suction nozzle pressing mechanisms 15 designed, and the confluence structure can select four eight-way confluence blocks 22 and one four-way confluence block 21, each eight-way confluence block 22 is connected to the four-way confluence block 21, and each eight-way confluence block 22 is connected to a group of 8 channel pressing mechanisms 25, so that the cache cup mechanism 11 is connected to the connection component, thereby improving the efficiency of extracting the cleaning liquid.

[0084] Alternatively, if Figure 4 As shown, the suction nozzle pressing mechanism 15 includes a suction nozzle 151 and a fourth one-way valve 152, and the suction nozzle 151 is connected to the cache cup mechanism 11 through the fourth one-way valve 152; the fourth one-way valve 152 is in a normally closed state, and when the channel pressing mechanism 25 and the suction nozzle pressing mechanism 15 are pressed, the fourth one-way valve 152 is opened.

[0085] Specifically, in the present embodiment, a fourth one-way valve 152 is disposed in the suction nozzle 151 of the suction nozzle pressing mechanism 15. The fourth one-way valve 152 may be a mechanical one-way valve. When the buffer cup mechanism 11 needs to be filled or drained, the fourth one-way valve 152 may be opened by a petal structure. When not in use, the fourth one-way valve 152 is closed to reduce the evaporation of the cleaning liquid to the external environment, thereby causing unnecessary safety accidents. The fourth one-way valve 152 may also be an electrically controlled valve, which may be automatically opened by the control device 3 during filling and draining. In addition, the channel pressing mechanism 25 has a pressing nozzle 251 and a connecting pipe. The pressing nozzle 251 is pressed with the suction nozzle 151, and the connecting pipe may be connected to a confluence structure, such as an eight-way confluence block 22.

[0086] Alternatively, if Figure 4As shown, the cache cup mechanism 11 includes a cache cup 111, a first pipeline 112, a second pipeline 113 and a flange structure 114; the flange structure 114 is assembled at the cup mouth of the cache cup 111, and the upper end of the flange structure 114 is connected to the fourth one-way valve 152 through the first pipeline 112, and the lower end is connected to the interior of the cache cup 111 through the second pipeline 113, and the overflow pipe 13 is connected to the cache cup 111.

[0087] Specifically, in the present embodiment, each cache cup mechanism 11 includes a cache cup 111, a first pipeline 112, a second pipeline 113 and a flange structure 114. The provision of the flange structure 114 facilitates the assembly and disassembly of the first pipeline 112 and the second pipeline 113 with the cache cup 111. For example, when the cache cup 111 needs to be cleaned, the first pipeline 112 and the second pipeline 113 can be disassembled by loosening the flange structure 114. On the other hand, the flange mechanism can be assembled in a sealed manner during assembly, making it difficult for the cleaning liquid in the cache cup 111 to evaporate into the outside air, thereby further improving the safety of the structure.

[0088] In some embodiments, the cache cup mechanism 11 may further include a perspective mirror, which may be disposed on the cache cup 111 to facilitate observation of the situation inside the cache cup 111 .

[0089] Alternatively, if Figure 2 and Figure 8 As shown, the overflow chamber assembly 12 includes an overflow chamber 121 and a first one-way valve 122, a second one-way valve 123 and a third one-way valve 124 arranged on the overflow chamber 121; the liquid injection and discharge equipment 2 also includes a liquid pumping, air intake and exhaust assembly 23, and the liquid pumping, air intake and exhaust assembly 23 includes a first air intake pipe 231, a first exhaust pipe 232, a first liquid pumping pipe 233, a first pressing mechanism, a second pressing mechanism and a third pressing mechanism.

[0090] The first air intake pipe 231 is connected to the first one-way valve 122 through a first pressing mechanism, so as to input gas into the overflow chamber 121 through the first air intake pipe 231; the first exhaust pipe 232 is connected to the second one-way valve 123 through a second pressing mechanism, so that the gas in the overflow chamber 121 can be discharged through the first exhaust pipe 232; one end of the first liquid extraction pipe 233 is connected to the third one-way valve 124 through a third pressing mechanism, and the other end is connected to the waste liquid storage assembly 5, so that the cleaning liquid in the overflow chamber 121 can flow to the waste liquid storage assembly 5 through the first liquid extraction pipe 233.

[0091] The first air intake pipeline 231, the first exhaust pipeline 232, and the first liquid extraction pipeline 233 are respectively provided with a first air-controlled valve, a second air-controlled valve, and a third air-controlled valve connected to the control device 3 to control the on-off of each pipeline respectively.

[0092] Specifically, in this embodiment, the three pressing mechanisms are pressed together with the three one-way valves provided on the overflow chamber 121 respectively, and can make them open. Among them, the first one-way valve 122 (an air intake one-way valve) is used when the cleaning tool 1 is in the second position (chemical formation storage position) to clean the negative pressure component and the liquid in the buffer cup 111 is extracted by negative pressure. The first one-way valve 122 opens due to the pressure difference, and the gas enters the buffer cup 111, which is convenient for extracting the cleaning liquid and cleaning the negative pressure component. At this time, the first air intake pipe 231 can pass nitrogen, so that the nitrogen enters the buffer cup 111 to realize the above process.

[0093] The second one-way valve 123 (an exhaust one-way valve) is used to break the vacuum of the formation system (i.e., the negative pressure component) after the cleaning work is completed, and the cleaning liquid flows back to the buffer cup 111 through gravity. At this time, the second one-way valve 123 opens due to the pressure difference, and the first exhaust pipe 232 is connected, so that the buffer cup 111 can complete the liquid filling step by the way.

[0094] The third one-way valve 124 is installed in the liquid injection and discharge device 2. When the buffer cup 111 is full, the overflowing cleaning liquid flows into the overflow chamber 121 due to the height difference. The liquid injection and discharge device 2 extracts the excess cleaning liquid through the third one-way valve 124 to prevent the overflow chamber 121 from being overfilled and alarming. After a period of time, the first liquid extraction channel is also connected, and the excess cleaning liquid in the overflow chamber 121 is extracted into the waste liquid storage assembly 5.

[0095] In the above structure, the first air inlet pipe 231, the first exhaust pipe 232 and the first liquid extraction pipe 233 are respectively connected to an air control valve, and the air control valves respectively control whether the three pipes are connected, so that the entire liquid injection, liquid discharge or cleaning process can be automatically controlled, further improving the cleaning efficiency. Among them, the overflow chamber assembly 12 can also include a liquid level visual tube 125, a liquid discharge manual valve 126 and a liquid level detection sensor. When the liquid level in the overflow chamber 121 is too high, the liquid level height can be observed through the liquid level visual tube 125 or detected by the liquid level detection sensor, so that when the liquid in the overflow chamber 121 is too full, an alarm can be sounded, thereby improving the safety of the device.

[0096] Alternatively, if Figure 5 and Figure 7 As shown, the liquid injection and discharge equipment 2 also includes a residual liquid receiving mechanism 24, which can be connected to the waste liquid storage component 5, and the confluence structure is also connected to a second air inlet pipe 211, and the second air inlet pipe 211 is used to transport gas; when the cleaning tool 1 is not in the first position, the residual liquid receiving mechanism 24 can be connected to the channel pressing mechanism 25, and gas is input into the confluence structure through the second air inlet pipe 211.

[0097] Specifically, in this embodiment, after the waste liquid cup in the buffer cup 111 of the cleaning tool 1 is evacuated and clean cleaning agent is injected, the residual liquid receiving mechanism 24 is pressed with the channel pressing mechanism 25, and then the negative pressure power source works, and nitrogen or other gases are input into the confluence structure through the second air inlet pipe 211. The cleaning liquid remaining in the liquid injection and discharge device 2 flows to the waste liquid storage tank 51 under the left and right negative pressure, thereby reducing the explosion risk caused by the cleaning liquid being exposed to the air.

[0098] Alternatively, if Figure 7 As shown, the residual liquid receiving mechanism 24 includes a residual liquid receiving manifold 243 and a driving member, and the driving member can drive the residual liquid receiving manifold 243 to connect with the channel pressing mechanism 25; wherein, the residual liquid receiving manifold 243 includes a plurality of residual liquid interfaces 2431 and a residual liquid outlet 2432, and the plurality of residual liquid interfaces 2431 are connected to the channel pressing structure one by one, and the residual liquid outlet 2432 is connected to the waste liquid storage component 5.

[0099] Specifically, in this embodiment, after the cleaning tool 1 has completed the extraction of waste liquid and the injection of clean cleaning liquid, the driving member of the residual liquid receiving mechanism 24 drives the residual liquid receiving manifold 243 to move to a position where it can be connected to the channel pressing mechanism 25, so as to extract the residual waste liquid in the liquid injection and discharge device 2. Among them, the driving member can be set in multiple groups according to the needs, and each group of driving members can be set as a lifting cylinder 241 and two transverse cylinders 242, so as to drive the residual liquid receiving manifold 243 to move to a suitable position. Among them, the lifting cylinder 241 is used to move the residual liquid receiving manifold 243 in the vertical direction, and the transverse cylinder 242 is used to move the residual liquid receiving manifold 243 in the horizontal direction.

[0100] Alternatively, if Figure 5 As shown, the power source includes a positive pressure power source and a negative pressure power source, the cleaning liquid storage component 4 can be connected to the positive pressure power source, and the waste liquid storage component 5 can be connected to the negative pressure power source. Among them, the positive pressure power source and the negative pressure power source can come from the positive pressure source and the negative pressure source of the factory building, which not only avoids the waste of space caused by setting up a power source separately, but also improves the problem of low efficiency when using a peristaltic pump as a power source in the prior art, improves the speed of replacing the cleaning liquid by the buffer cup mechanism 11, and improves the cleaning efficiency when in the formation storage position (the cleaning tool 1 is located in the second position).

[0101] In one embodiment, the principle can be referred to Fig.11The liquid injection and discharge equipment 2 also includes a cleaning liquid storage component 4, a waste liquid storage component 5 and a residual liquid receiving mechanism 24. Among them. A1 to A19 are all air-controlled valves or manual valves, wherein the air-controlled valves can be connected to the control device 3, and the manual valves can be manually opened or closed to control the on and off of each pipeline. P1 is the place where the factory waste liquid is connected (the factory needs to turn on negative pressure extraction), P2 is connected to the positive pressure source, P3 is the clean cleaning agent pumped into the factory through the positive pressure source, P4 is the place where the factory waste gas and waste liquid are connected, which can be used for pressure relief, P5 is connected to the nitrogen pipeline, and the gas entering the tank can be used for pressure relief, and P6 is connected to the negative pressure source.

[0102] like Fig. 9 As shown, the cleaning liquid storage assembly 4 includes a cleaning liquid storage tank 41 and a first liquid inlet pipe 42, a third air inlet pipe 43, a first discharge pipe, a first liquid outlet pipe 45 and a positive pressure source pipe 46 connected to the cleaning liquid storage tank 41; the cleaning liquid storage tank 41 can be connected to a positive pressure power source through the positive pressure source pipe 46, so that the cleaning liquid can flow to the cleaning liquid storage tank 41 through the first liquid inlet pipe 42, and flow to the cache cup mechanism 11 through the first liquid outlet pipe 45, the third air inlet pipe 43 is used to inject gas into the cleaning liquid storage tank 41, and the first discharge pipe is used to discharge the waste gas and waste liquid in the cleaning liquid storage tank 41.

[0103] Specifically, the cleaning liquid storage tank 41 is equipped with a positive pressure source pipeline 46 for receiving the positive pressure power source of the factory building, a first liquid inlet pipeline 42 for receiving clean liquid pumped into the factory building, a third air inlet pipeline 43 for receiving gas, a first discharge pipeline for discharging waste gas and waste liquid, and a first liquid outlet pipeline 45 for pumping clean liquid into the buffer cup mechanism 11. Each pipeline has a corresponding air control valve to control whether it is connected. In addition, the positive pressure source pipeline 46 can also be connected to a pressure regulating valve and a pressure transmitter to adjust the appropriate positive pressure for injection. The first discharge pipeline and the third air inlet pipeline 43 are discharged to a special location in the factory building after merging. When the cleaning liquid storage tank 41 needs maintenance, the first discharge pipeline is opened and the third air inlet pipeline 43 is also opened, so as to conveniently discharge the excess cleaning liquid in the cleaning liquid storage tank 41.

[0104] like Fig.10 As shown, the waste liquid storage assembly 5 includes a waste liquid storage tank 51 and a second liquid extraction pipe 52 connected to the waste liquid storage tank 51, a waste liquid collection pipe 53, a fourth air intake pipe 54, a waste liquid discharge pipe 55 and a negative pressure source pipe 56; the waste liquid storage tank 51 can be connected to the negative pressure power source through the negative pressure source pipe 56, so that the cleaning liquid in the buffer cup mechanism 11 can flow into the waste liquid storage tank 51 through the second liquid extraction pipe 52, the residual liquid receiving mechanism 24 is connected to the waste liquid storage tank 51 through the waste liquid collection pipe 53, the fourth air intake pipe 54 is used to inject gas into the waste liquid storage tank 51, and the waste liquid discharge pipe 55 is used to discharge the cleaning liquid in the waste liquid storage tank 51.

[0105] Specifically, the waste liquid storage tank 51 is equipped with a negative pressure source pipeline 56 for receiving the negative pressure source of the factory building, a waste liquid receiving pipeline 53 for receiving the residual liquid receiving mechanism 24, a second liquid extraction pipeline 52 for extracting the cleaning liquid of the tooling buffer cup 111, a pipeline for extracting excess cleaning liquid from the tooling overflow chamber 121, a fourth air intake pipeline 54 for receiving nitrogen, and a waste liquid discharge pipeline 55. Similarly, each pipeline has a corresponding air control valve to control whether it is conductive. The negative pressure source pipeline 56 is connected to a vacuum pressure valve and a pressure transmitter to adjust the appropriate negative pressure for liquid extraction. When the waste liquid storage tank 51 needs maintenance, the tank waste liquid discharge pipeline 55 is opened, and the fourth air intake pipeline 54 is also opened, so as to conveniently discharge the excess cleaning liquid in the waste liquid storage tank 51.
