Description

Technical Field

[0001] The present invention relates to the technical field of cleaning tooling, and particularly relates to a cleaning tooling structure for a formation negative pressure nozzle and pipeline. Background Art

[0002] During the formation charging process of the battery, a large amount of gas is generated due to internal reactions. If the gas is not completely discharged, serious lithium deposition and black spot phenomena will occur on the battery interface. Usually, a negative pressure is pumped to discharge the gas generated during the battery charging process. However, during the process of pumping negative pressure to exhaust gas, the electrolyte will also be drawn into the negative pressure pipeline along with the gas. The long-term accumulation of the electrolyte in the negative pressure pipeline will cause crystallization, which will further lead to the blockage of the negative pressure pipeline and affect the vacuum pumping effect.

[0003] In view of the above problems, the patent document CN112838282A disclosed a lithium battery negative pressure formation system with a cleaning pipeline and its cleaning process on May 25, 2021. It specifically discloses that first, the residual liquid electrolyte in the negative pressure system is blown out by a slightly positive pressure, and then the gaseous product is obtained by the reaction of hot air with lithium hexafluorophosphate crystals in the pipeline, effectively solving the problem of residual and crystallization of the electrolyte in the negative pressure pipeline after battery formation, and thus ensuring the normal operation of the negative pressure system. The patent document CN218395091U disclosed a negative pressure formation nozzle and a negative pressure formation cleaning device on January 31, 2023. The negative pressure formation nozzle provided by this prior art can suck the waste gas and electrolyte at the battery liquid injection port through the suction port, thereby reducing the phenomenon that a large amount of waste gas accumulated at the battery liquid injection port during the battery formation process drives the electrolyte to overflow and stain the battery surface. This prior art also specifically discloses a negative pressure formation cleaning device, and its technical solution includes a hollow joint. The top of the joint is assembled to the negative pressure box and communicated with the negative pressure chamber, and the bottom of the joint is assembled and communicated with the negative pressure formation nozzle, that is, it discloses pumping out the residues in the pipeline through vacuum negative pressure.

[0004] In the prior art such as the above patents, multiple joints for detection and cleaning are synchronously docked with multiple negative pressure nozzles one by one. Due to the existence of mechanical errors, the fixed joints are likely to cause some joints to be not tightly docked with the negative pressure nozzles. Therefore, there is an urgent need for a cleaning tooling structure for a formation negative pressure nozzle and pipeline to solve the above problems. Summary of the Invention

Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0031] Please refer to Figure 1-6 , a cleaning tooling structure for a formation negative pressure suction nozzle and pipeline provided by an embodiment of the present invention includes a bracket 1, and further includes: an interaction chamber 2, which is arranged on the bracket 1; an air nozzle 3, which is connected to the upper end of the interaction chamber 2 through a hose 4, and the upper end thereof is arranged in a conical shape; a positioning frame 5, which is fixedly arranged on the upper end of the interaction chamber 2, and a kit 6 is connected therein through a calibration assembly, and the kit 6 is sleeved outside the air nozzle 3; an airbag sleeve 7, which is fixedly arranged inside the kit 6 and sleeved on the air nozzle 3, and the upper end thereof can extend out of the kit 6 under inflation and expansion.

[0032] Specifically, the bracket 1 is in the shape of a rectangular frame, with the upper end supporting the interaction chamber 2 to make it horizontally arranged; the upper end of the interaction chamber 2 is set higher than the bracket 1; the air nozzle 3 is in the shape of a nozzle and can be inserted into the negative pressure suction nozzle from the upper end; the negative pressure suction nozzle is arranged at the lower end of the forming negative pressure pipeline, and multiple are arranged side by side in a row. The air nozzles 3 correspond to the negative pressure suction nozzles one by one. The multiple air nozzles 3 are arranged side by side in a row and are spaced apart; the hose 4 is preferably a corrugated pipe, which supports the air nozzle 3 and at the same time enables the air nozzle 3 to swing or deflect under external force; the positioning frame 5 is rectangular, and the four corners are fixedly connected to the upper end of the interaction chamber 2 through vertical support rods. The height of the positioning frame 5 corresponds to the side wall of the air nozzle 3 and is arranged around the outside of the air nozzle 3; the inner diameter of the sleeve 6 is set larger than the outer diameter of the air nozzle 3, and the sleeve 6 is arranged axially vertically; the outer wall of the airbag sleeve 7 is fixedly bonded to the inner wall of the sleeve 6, and a part of the upper end is not bonded to the inner wall of the sleeve 6, so that when the airbag sleeve 7 is inflated and expanded, its upper end can expand and extend out of the sleeve 6. There is a device (not shown in the figure) for inflating and deflating the airbag sleeve 7 on the interaction chamber 2, which is a prior art and will not be elaborated. In the actual use of this technical solution, when each air nozzle 3 is docked with the negative pressure suction nozzle, through the conical structure and mobility of the air nozzle 3, the initial insertion of each air nozzle 3 into the corresponding negative pressure suction nozzle can be realized. Subsequently, by inflating each airbag sleeve 7, the airbag sleeve 7 expands and fills the gap between the sleeve 6 and the air nozzle 3, so that the air nozzle 3 automatically aligns itself and aligns with the negative pressure suction nozzle under the offset movement provided by the alignment component. Thus, the air nozzle 3 is inserted straight into the corresponding negative pressure suction nozzle to avoid the generation of docking gaps caused by offset. At the same time, the upper end of the airbag sleeve 7 expands and extends out of the sleeve 6 to abut against the docking position of the air nozzle 3 and the negative pressure suction nozzle, strengthening the seal.

[0033] Compared with the prior art, a cleaning tooling structure for a forming negative pressure suction nozzle and pipeline proposed in the embodiment of the present invention connects the air nozzle 3 through the hose 4. Under the control of the alignment component, when each air nozzle 3 is docked with the negative pressure suction nozzle, through the conical structure and mobility of the air nozzle 3, the initial insertion into the negative pressure suction nozzle is realized. Subsequently, by inflating each airbag sleeve 7, the airbag sleeve 7 expands and fills the gap between the sleeve 6 and the air nozzle 3, so that the air nozzle 3 automatically aligns itself and aligns with the negative pressure suction nozzle under the offset movement provided by the alignment component. At the same time, the upper end of the airbag sleeve 7 expands and extends out of the sleeve 6 to abut against the docking position of the air nozzle 3 and the negative pressure suction nozzle, strengthening the seal.

[0034] As a preferred technical solution of this embodiment, the calibration assembly includes a calibration frame 8 that is elastically and movably arranged within a positioning frame 5. A kit 6 is elastically and movably connected within the calibration frame 8. The moving direction of the calibration frame 8 and the moving direction of the kit 6 are arranged to intersect on a horizontal plane. Specifically, the calibration frame 8 is rectangular. The two outer walls in the length direction of the calibration frame 8 are in contact with the inner wall of the positioning frame 5 and are provided with first sliders. The corresponding inner wall of the positioning frame 5 is provided with first chutes. The arrangement of the first sliders and the first chutes enables the calibration frame 8 to move horizontally. The two outer walls in the width direction of the calibration frame 8 are spaced from the inner wall of the positioning frame 5 and are oppositely provided with a set of springs, thereby maintaining the automatic centering of the calibration frame 8 within the positioning frame 5, and the calibration frame 8 can only move within the positioning frame 5 after being subjected to an external force; the two inner walls in the width direction of the positioning frame 5 are provided with second chutes, and the corresponding outer walls of the kit 6 are provided with second sliders. The kit 6 slides on a horizontal plane, and the sliding direction is perpendicular to the sliding direction of the calibration frame 8; another set of springs is oppositely arranged between the other two sides of the kit 6 and the inner walls in the length direction of the calibration frame 8, thereby maintaining the automatic centering of the kit 6 within the calibration frame 8, and the kit 6 can only move within the calibration frame 8 after being subjected to an external force; the movement of the kit 6 and the calibration frame 8 in two directions on the horizontal plane enables the nozzle 3 to freely offset and adjust its position.

[0035] As a preferred technical solution of this embodiment, a convex ring 9 is provided on the outer wall of the nozzle 3, and the inner side of the airbag sleeve 7 is clamped and arranged with the convex ring 9. Specifically, the setting of the convex ring 9 keeps the position of the nozzle 3 relative to the airbag sleeve 7 fixed after the airbag sleeve 7 is inflated and shaped, that is, maintains the height of the nozzle 3 to ensure that the nozzle 3 is inserted straight into the negative pressure suction nozzle.

[0036] As a preferred technical solution of this embodiment, a vacuum pump 10 is fixedly installed on the bracket 1. The air extraction end of the vacuum pump 10 is connected with an air extraction pipe 11. The air extraction pipe 11 is communicated with each nozzle 3 through an interaction component. A filter chamber 12 is arranged on the air extraction pipe 11, and a filter component for blocking the inflow of residual impurities into the vacuum pump 10 is arranged within the filter chamber 12. Specifically, the vacuum pump 10 is used to generate suction force in the air extraction pipe 11; the air extraction pipe 11 extracts air from the nozzle 3, and then extracts air from the negative pressure suction nozzle and the forming negative pressure pipeline; the interaction component is used to communicate each nozzle 3 with the air extraction pipe 11; the filter chamber 12 is arranged in the middle of the air extraction pipe 11 in a truncated manner, and the two opposite sides are respectively communicated with a section of the air extraction pipe 11; the filter component in the filter chamber 12 is used to block the residual impurities inhaled into the filter chamber 12 through a section of the air extraction pipe 11 communicating with the nozzle 3 from further inhaling into the section of the air extraction pipe 11 communicating with the vacuum pump 10. In the actual use of this technical solution, when the vacuum pump 10 is started, it generates suction force in the air extraction pipe 11, thereby generating suction force at the nozzle 3 to attract the residual impurities cleaned out from the negative pressure suction nozzle and the forming negative pressure pipeline to flow into the filter chamber 12. Then, under the blocking of the filter component, the residual impurities do not further inhale into the vacuum pump 10, thus remaining in the filter chamber 12, facilitating the collection and centralized treatment of the residual impurities, and protecting the vacuum pump 10.

[0037] As a preferred technical solution of this embodiment, the interaction component includes a shunt pipe 13 and a plurality of gas storage chambers 14 arranged in the interaction chamber 2. The shunt pipe 13 is respectively connected to each gas storage chamber 14 through a plurality of branch pipes 15, and the gas nozzles 3 are in one-to-one correspondence and communication with the gas storage chambers 14. The upper end of the air extraction pipe 11 is communicated with the shunt pipe 13. Specifically, the air extraction pipe 11 sequentially passes through the shunt pipe 13, the branch pipes 15, and the gas storage chambers 14 to extract air from the gas nozzles 3; the gas storage chambers 14 are used for the nitrogen filling function before air extraction.

[0038] As a preferred technical solution of this embodiment, a control valve 16 is provided between the gas nozzle 3 and the gas storage chamber 14, and a pressure gauge head 17 for monitoring the air pressure in the gas storage chamber 14 is provided on the outer wall of the interaction chamber 2. Specifically, the control valve 16 is used to control the on-off of the gas storage chamber 14 and the gas nozzle 3; the control valve 16 is preferably an electromagnetic valve; the pressure gauge head 17 is used to display the air pressure in the gas storage chamber 14.

[0039] As a preferred technical solution of this embodiment, a nitrogen pump 18 is fixedly installed on the bracket 1. The nitrogen pump 18 is connected to the shunt pipe 13 through an air delivery pipe 19, and a pressure gauge 20 is provided on the air delivery pipe 19. Specifically, the nitrogen pump 18 inputs nitrogen into the shunt pipe 13 through the air delivery pipe 19, and then the branch pipes 15 fill nitrogen into the gas storage chambers 14. The pressure gauge 20 is used to display the air pressure inside the air delivery pipe 19.

[0040] The above nitrogen filling structure has the following functions:

[0041] Pipeline blockage detection: By using the nitrogen gas storage chamber 14 with a constant pressure, when it is opened, observe the change in the nitrogen gas pressure leakage value through the pressure gauge head 17 to determine whether the pipeline is blocked;

[0042] Pipeline cleaning operation: Use clean nitrogen for nitrogen filling. Through the fluctuation of different air pressures, a way similar to acoustic vibration is formed to break and dredge the crystals blocked inside the pipeline;

[0043] Working principle: First, connect the air nozzle 3 to the negative pressure suction nozzle; then, the vacuum pump 10 conducts a vacuum test on the negative pressure suction nozzle pipeline to ensure the correct connection of the negative pressure suction nozzle. When a certain vacuum value is reached, maintain the pressure for 5 - 8S; then turn off the vacuum pump 10 and switch to the nitrogen pump 18 for inflation to fill the corresponding gas storage cavity 14 with nitrogen, and the required air pressure value is 0.2 - 0.3mpa; then, through the control valve 16, open the valve of the gas storage cavity 14 for a nitrogen pressure relief test. It is required that within 3 - 5s, the air pressure value leaks to 0.1 - 0.2mpa. If the pipeline does not meet the requirements, it means there is a blockage in the pipeline; for the pipeline blockage problem, close the valve of the corresponding gas storage cavity 14 again, and then fill the gas storage cavity 14 with nitrogen. This time, fill the nitrogen pressure to 0.6 - 0.8mpa, and then conduct pressure relief. When the pressure is relieved to 0.1 - 0.2mpa, repeat the inflation - deflation operation. Three times form a cleaning operation cycle; finally, turn off the nitrogen pump 18, open the vacuum pump 10, and suck out the residues in the pipeline. Keep the vacuum for 10 - 20S. The above is a complete cleaning process. According to the actual situation, the number of nitrogen cleaning cycles can be appropriately increased, and according to the actual situation, the nitrogen can be heated and dried to further improve the cleaning effect.

[0044] As a preferred technical solution of this embodiment, the filtering component includes a convex body 21 arranged in the filtering chamber 12. An air vent 22 communicating with one end of the air extraction pipe 11 connected to the vacuum pump 10 is arranged on the convex body 21. A net plate 23 for blocking is arranged in the air vent 22. Specifically, the convex body 21 is arranged on the inner wall of the filtering chamber 12. One section of the air extraction pipe 11 connected to the vacuum pump 10 has one end connected to the vacuum pump 10 and the other end connected to the filtering chamber 12. The convex body 21 corresponds to this end of this section of the air extraction pipe 11, and the air vent 22 also communicates with this end of this section of the air extraction pipe 11; the net plate 23 can completely block the air vent 22 to filter residual impurities.

[0045] As the preferred technical solution of this embodiment, the mesh plate 23 can be raised and lowered and arranged in the vent 22, and the lower end can move through the convex body 21, and a shovel block 24 is arranged on the inner bottom surface of the vent 22, which fits the outer side of the mesh plate 23, and a sealing plate 25 is hinged at the lower end of the filter bin 12, and a limiting component is arranged at the free end of the sealing plate 25 to limit itself in a state of closing the filter bin 12. When the sealing plate 25 is in a state of closing the filter bin 12, the lower end of the mesh plate 23 abuts the sealing plate 25 to be in the highest position within the lifting range, and specifically, the limiting component includes a push block 29 elastically and movably arranged at the free end of the sealing plate 25, and a hook block 30 is fixedly arranged on the push block 29 and slides through the sealing plate 25, and a hook groove 31 matching the hook block 30 is arranged on the inner wall of the filter bin 12. A groove is provided on the inner wall of the vent 22 for the lifting and lowering of the mesh plate 23. When the mesh plate 23 is in the highest position formed by the lifting, the vent 22 is completely blocked; during the descent process, the outer surface of the mesh plate 23 is scraped by the shovel block 24 to be cleaned; the sealing plate 25 can open and close the lower end of the filter bin 12 by rotation, which is used to concentrate the discharge of residual impurities; a sealing strip is provided at the position where the sealing plate 25 contacts the filter bin 12, and when the sealing plate 25 is closed, the filter bin 12 can be sealed; a receiving groove is provided at the free end of the sealing plate 25, and the storage groove is connected to a push block 29 by another set of springs, and one end of the push block 29 extends out of the storage groove. When the sealing plate 25 is closed, the hook block 30 hooks the hook groove 31 from the inner side of the filter bin 12, thereby stabilizing the sealing plate 25 in the closed position, and when the push block 29 is pushed, the push block 29 drives the hook block 30 to disengage the hook groove 31, so that the sealing plate 25 can be rotated downward to open.

[0046] As the preferred technical scheme of this embodiment, a stopper 26 is elastically provided in the vent 22, a top block 27 is provided on the inner side of the upper end of the mesh plate 23, and a shifting block 28 is provided on the upper end of the stopper 26 near the side of the mesh plate 23 above the top block 27. Specifically, the stopper 26 is used to block the opening where the exhaust pipe 11 connects with the vent 22, and the stopper 26 is arranged in contact with the inner wall of the exhaust pipe 11 where the vent 22 connects; a concave hole is provided on the upper end of the stopper 26, and a spring is connected in the concave hole, and the upper end of the spring is connected to the inner top surface of the vent 22, thereby keeping the stopper 26 moving downward to block the opening of the exhaust pipe 11; when the mesh plate 23 is resisted by the closed sealing plate 25, it is in the highest position, and at this time the mesh plate 23 is held to support the shift block 28 upward through the top block 27, thereby making the block 26 in the highest position so as not to block the opening of the exhaust pipe 11. After the sealing plate 25 is opened, the lower end of the mesh plate 23 is not supported, and the block 26 automatically moves downward under the elastic force to block the opening of the exhaust pipe 11. At the same time, the block 26 also presses the top block 27 downward through the shift block 28, thereby moving the mesh plate 23 downward to cooperate with the shovel block 24 to clean the outer surface. In addition, the mesh plate 23 can be further pulled down to extend out of the filter bin 12, and can be further cleaned with a brush. Moreover, since the exhaust pipe 11 is blocked by the block 26 at this time, dust and impurities will not enter the exhaust pipe 11 during the cleaning process.

Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.
