Description

Technical Field

[0001] The utility model relates to the technical field of battery production and manufacturing equipment, and more specifically, to a liquid filling cup cleaning device. Background Art

[0002] In the current battery manufacturing industry, liquid injection is a crucial process, and the quality of liquid injection will directly affect the battery yield. Liquid injection refers to injecting electrolyte into the cavity through a certain process (such as vacuum, pressure, time), so that part of the electrolyte infiltrates into the battery cell (positive and negative pole pieces, diaphragm), and the other part occupies the unfilled space.

[0003] The bell-type liquid injection machine is a key manufacturing equipment in the liquid injection process. The accuracy and stability of its operation are crucial to the entire production process. It is mainly used to accurately inject electrolyte into the battery. This equipment plays a key role in the battery manufacturing process with its unique working principle and efficient and stable performance.

[0004] In this equipment, the cup (liquid injection cup) fixture is an indispensable component, which directly undertakes the important task of fixing and positioning the cup. However, the working environment of the cup fixture is quite complicated.

[0005] During the filling process, the end faces of the cups' liquid inlets are in contact with the electrolyte almost all the time, and at the same time, the end faces of the cups' liquid inlets are directly exposed to the air without any shielding. In such an environment, electrolyte crystals are easily formed on the end faces of the cups' liquid inlets due to negative pressure during the circulation process. These crystals not only affect the appearance of the cups, but more importantly, they will gradually accumulate over time.

[0006] When these crystals accumulate to a certain thickness, they will have an adverse effect on the pressing of the cup, and then affect the airtightness of the injection. This may not only lead to poor injection effect, but also have a negative impact on the performance of the entire battery. In addition, more seriously, if the crystals accidentally fall into the cup and are injected into the battery cell along with the electrolyte, it may cause the battery cell to be contaminated, thus affecting the safety and stability of the battery.

[0007] Faced with this challenge, the cleaning method currently commonly used in the industry is manual cleaning. However, this method has many disadvantages. First, manual cleaning is inefficient and consumes a lot of manpower and time. Second, it is difficult to ensure uniformity and thoroughness during manual cleaning, which can easily leave dead corners and omissions. More seriously, manual cleaning also has certain safety risks. For example, the cleaning agent may accidentally flow into the cup, causing contamination or damage to the battery cell.

[0008] Therefore, in response to this problem, it is urgent to develop a device that can automatically clean the cup. Utility Model Content

[0043] like Figure 1-Figure 4 As shown, the utility model proposes a cleaning device for the liquid injection cup on the bell-shaped liquid injection machine, which has efficient, uniform and thorough cleaning capabilities, while also ensuring the safety and reliability of the cleaning process. By introducing such a device, not only can the cleaning efficiency and quality be greatly improved, production costs and manpower input be reduced, but also various problems and risks that may occur during manual cleaning can be effectively avoided.

[0044] It should be noted that the liquid filling cup is composed of a cup body 10 and a cup cover 20. The cup body 10 and the cup cover 20 can be an integrally formed structure; they can also be a split structure, and the two are connected by bolts or screws. Of course, the split design is not only convenient for processing and installation, but also for maintenance.

[0045] A liquid outlet port 11 is provided at the bottom of the cup body 10, and a liquid inlet port 21 is provided on the cup cover 20. The electrolyte is transported into the cup body 10 through the liquid inlet port 21 and then discharged from the liquid outlet port 11. Since the surface of the cup cover 20 is always in contact with the electrolyte, electrolyte crystals are easily formed on the surface. In order to facilitate the cleaning of the electrolyte crystals, a cleaning device is provided.

[0046] The cleaning device of the present application is described in detail through the following embodiments.

[0047] Embodiment 1:

[0048] like Figure 2-Figure 4 As shown, in this embodiment, the cleaning device includes: a housing 100, which can be adapted to the cup cover 20, and after being arranged on the cup cover 20, a receiving chamber 110 is formed between the housing 100 and the cup cover 20; a first port 120 and a second port 130 connected to the receiving chamber 110 are opened on the housing 100; and a sealing portion 200, which is located in the receiving chamber 110 and seals and covers the liquid inlet port 21;

[0049] The first port 120 is formed as a port for the injection and outflow of the cleaning liquid, and the second port 130 is formed as a port for exhausting the containing chamber 110 .

[0050] In the present technical scheme, when cleaning the cup cover 20 of the liquid filling cup, the liquid inlet port 21 on the cup cover 20 is first blocked by the sealing part 200, and then the shell 100 is set on the cup cover 20, and then the liquid inlet and outlet pipes and the air pipe are respectively connected to the first port 120 and the second port 130; firstly, hot water or other detergent is injected into the liquid inlet and outlet pipes, and after a certain amount of cleaning liquid is injected into the containing chamber 110, the valves on the liquid inlet and outlet pipes are closed, and after soaking for a certain period of time, the valves on the liquid inlet and outlet pipes are opened again, and the pumping mode is turned on to pump out the liquid in the containing chamber 110, and the valves on the liquid inlet and outlet pipes are closed; then the valve on the air pipe is opened, and the containing chamber 110 is negatively evacuated, so that the liquid on the cup cover 20 and the inner wall of the shell 100 is pumped out, and after the containing chamber 110 is completely in a dry state, the cleaning of the cup cover 20 is completed.

[0051] It should be noted that the cleaning device further includes: a fixing portion 300, which is arranged between the outer shell 100 and the cup cover 20, and is used to seal the two.

The fastener 330 is arranged on the first connecting plate and the second connecting plate, and can adjust the inner diameter of the chamber enclosed by the first clamp ring 310 and the second clamp ring 320. Holes are provided on the first connecting plate and the second connecting plate.

[0056] The fastener 330 includes: a bolt 331 and a nut 332 ; the bolt 331 passes through a hole on the first connecting plate and a hole on the second connecting plate and is threadedly connected with the nut 332 .

[0057] In the present technical solution, the clamp is composed of a semi-annular first clamp ring 310, a semi-annular second clamp ring 320 and a fastener 330. After the outer shell 100 is put on the cup cover 20, the first clamp ring 310 and the second clamp ring 320 are then put on the outer shell 100, and then the two are connected by the fastener 330. The tightness between the outer shell 100 and the cup cover 20 can be adjusted by adjusting the protruding length of the bolt 331.

[0058] In this embodiment, the housing 100 is optimized to have an annular groove opened along its circumferential direction, and the clamp is sleeved in the annular groove. The annular groove is provided to limit the position of the clamp.

[0059] Embodiment 2:

[0060] This embodiment is a further improvement made on the basis of the first embodiment.

[0061] like Figure 2 and Figure 3 As shown, in this embodiment, the housing 100 is divided into an upper housing 101 and a lower housing 102, the upper housing 101 is a conical structure, and the lower housing 102 is a ring structure;

[0062] The liquid inlet port 21 is located on the upper shell 101 , and the lower shell 102 is sleeved on the cup cover 20 . The upper shell 101 and the lower shell 102 are detachably connected and connected by bolts or screws.

[0063] In this technical solution, the housing 100 is divided into two parts to facilitate production.

[0064] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
