Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a novel battery tab cleaning device. Background Art

[0002] At present, lithium-ion batteries have the advantages of high specific energy, many cycles and long storage time. They are not only widely used in portable electronic devices (such as mobile phones, digital cameras and laptops), but also widely used in large and medium-sized electric equipment such as electric vehicles, electric bicycles and electric tools. Therefore, the performance requirements for lithium-ion batteries are getting higher and higher.

[0003] In the process of lithium battery manufacturing, the role of the tab is particularly critical. The tab is the bridge for energy transmission between the internal electrode of the battery and the external circuit, and its surface quality control is crucial. On the one hand, the cleanliness of the tab surface is extremely high, and any slight contamination may affect the efficiency and stability of the chemical reaction inside the battery, resulting in a decrease in battery performance or a shortened life. On the other hand, the dimensional accuracy and consistency of the tab directly determine the difficulty of the battery assembly process and the safety performance of the final product. For example, if the tab is too long or uneven, it may increase the risk of battery short circuit.

[0004] In the actual production process, especially in the battery winding process, the tabs scraping against the tray during the relative movement between the tabs and the tray is a problem that cannot be ignored. If the tabs scrape against the tray, the plastic or other materials on the tray may produce debris due to friction, and may adhere to the surface of the tabs. The presence of these tiny particles will not only increase the internal resistance of the battery and reduce the battery's charging and discharging efficiency, but may also pierce the battery's diaphragm and cause a short circuit between the positive and negative electrodes. In severe cases, it may even cause safety hazards such as thermal runaway, posing a threat to the overall performance of the battery and the safety of users.

[0005] It should be noted that after the manufacture of the tabs, the tabs will be packaged in a specific way to facilitate transportation, storage and subsequent automated assembly processes. The commonly used packaging form is called "disc" or "winding". This packaging method is to wind the entire metal strip tab into a disc, just like a magnetic tape or coil, neatly arranged and wound on a round pallet to form a tab roll. This helps to reduce the occupied space and ensure that the tabs will not be damaged during transportation. In the process of unwinding the tabs from the tray, due to the deviation in the installation position accuracy of the tray, the design defects of the tray itself, and the inappropriate tension control of the tabs (too tight or too loose), it is easy for the edge of the tab to contact the non-load-bearing area of ​​the tray and cause scratches, that is, the tabs scratch the tray.

[0006] Therefore, there is an urgent need to develop a technology that can solve the above technical problems. Utility Model Content

[0007] The utility model aims to provide a novel battery tab cleaning device in view of the technical defects in the prior art.

[0008] To this end, the utility model provides a novel battery tab cleaning device, including a wiping cleaning device, an air blowing device and a dust suction device;

[0009] A wiping and cleaning device, in contact with the surface of the battery tab, for wiping impurities on the surface of the battery tab;

[0010] The blowing device is used to blow away impurities on the surface of the battery tab after being wiped by the wiping cleaning device through a high-pressure airflow;

[0011] A dust suction device, arranged corresponding to the air blowing device, for sucking in impurities blown out by the air blowing device during the process of blowing the battery tab;

[0012] The wiping cleaning device comprises a first wiping pad supporting block and a second wiping pad supporting block which are arranged vertically;

[0013] A first wiping pad and a second wiping pad are respectively arranged on opposite sides of the first wiping pad supporting block and the second wiping pad supporting block;

[0014] A battery tab, located between the first wiping pad and the second wiping pad;

[0035] See also Figures 1 to 3 The utility model provides a novel battery tab cleaning device, which can be applied to the production process of cylindrical lithium-ion batteries. As a supporting device for an existing lithium-ion battery winding machine, the utility model comprises: a wiping cleaning device 5, an air blowing device 6 and a dust collecting device 8;

[0036] The wiping and cleaning device 5 is in contact with the surface of the battery tab 4 and is used to wipe impurities on the surface of the battery tab 4;

[0037] It should be noted that the battery tab 4 can be any battery tab having impurities on the surface and requiring cleaning, or can be a battery tab having impurities on the surface due to scraping of the material tray.

[0038] The blowing device 6 is used to blow away impurities on the surface of the battery tab 4 after being wiped by the wiping and cleaning device 5 through a high-pressure airflow, and to perform a drying process at the same time (i.e., the airflow plays a role in the drying process);

[0039] The dust suction device 8 is provided corresponding to the air blowing device 6 , and is used to suck in impurities (such as dust and debris, etc.) blown out by the air blowing device 6 during the process of blowing the battery tab 4 .

[0040] In the present utility model, the specific implementation is as follows: Figure 2 As shown, the wiping cleaning device 5 comprises a first wiping pad (eg wool felt) supporting block 53 and a second wiping pad (eg wool felt) supporting block 56 which are distributed up and down;

[0041] A first wiping pad 54 and a second wiping pad 55 are respectively disposed on opposite sides of the first wiping pad supporting block 53 and the second wiping pad supporting block 56;

[0042] The battery tab 4 is located between the first wiping pad 54 and the second wiping pad 55;

[0043] The upper and lower sides of the battery tab 4 are in contact with the surfaces of the first wiping pad 54 and the second wiping pad 55 respectively.

[0044] In a specific implementation, the first wiping pad 54 and the second wiping pad 55 are preferably made of wool felt.

[0045] In specific implementation, the first wiping pad supporting block 53 and the second wiping pad supporting block 56 are provided with a first wiping pad embedding groove and a second wiping pad embedding groove respectively on opposite sides thereof;

[0046] The first wiping pad embedding groove and the second wiping pad embedding groove are respectively embedded with a first wiping pad 54 and a second wiping pad 55 .

[0047] Further, the bottom surface height of the first wiping pad 54 is lower than the bottom opening height of the first wiping pad embedded in the groove;

[0048] The height of the top surface of the second wiping pad 55 is higher than the height of the top opening of the groove into which the second wiping pad is embedded.

[0049] In a specific implementation, one end of the first wiping pad supporting block 53 and one end of the second wiping pad supporting block 56 on the opposite side are connected (for example, hinged).

[0050] In specific implementation, the first wiping pad supporting block 53 is connected to a liquid storage device 2;

[0051] The liquid storage device 2 is used to provide cleaning liquid 23 for the first wiping pad 54 arranged on the first wiping pad supporting block 53. The specific structural design is as follows:

[0052] A liquid injection through hole is provided on the top of the first wiping pad supporting block 53;

[0053] The lower end of the liquid injection through hole is connected to the top surface of the first wiping pad 54;

[0054] The upper end of the liquid injection through hole is connected to one end of the liquid guide tube flow regulating valve 52;

[0055] The other end of the liquid guide tube flow regulating valve 52 is connected to a liquid port at one end of the solenoid valve 3 through the solenoid valve liquid guide tube 51;

[0056] The other end of the solenoid valve 3 is connected to the liquid outlet of the liquid storage device 2 .

[0057] Furthermore, the liquid storage device 2 includes a liquid storage tank body 22 of a hollow structure;

[0058] The liquid storage tank body 22 is pre-injected with cleaning liquid 23;

[0059] A liquid storage tank top cover 21 is provided on the top opening of the liquid storage tank body 22;

[0060] The liquid outlet at the bottom of the liquid storage tank body 22 is connected to the liquid outlet at the other end of the solenoid valve 3 through a liquid storage tank liquid guide tube 24.

[0061] Furthermore, a vent is provided on the top cover 21 of the liquid storage tank;

[0062] The vent is connected to one end of the pressure reducing valve 1 through a pressure reducing valve outlet pipe 11;

[0063] The other end of the pressure reducing valve 1 is connected to one end of the pressure reducing valve air inlet pipe 12;

[0064] The other end of the pressure reducing valve air inlet pipe 12 is connected to an air outlet pipe of an external compressed gas source (such as a compressed gas cylinder).

[0065] It should be noted that the other end of the pressure reducing valve air inlet pipe 12 is flexibly connected to the air outlet pipe of an external compressed gas source (such as a compressed gas cylinder) through a two-way or three-way joint. This design improves the portability and installation flexibility of the entire device. When the solenoid valve 3 is opened, the inside of the liquid storage tank 2 is subjected to the appropriate pressure adjusted by the pressure reducing valve 1, so that the cleaning liquid 23 can be smoothly pushed out according to the required amount and finally delivered to the position of the wiping pad (such as wool felt) for cleaning.

[0066] It should also be noted that in the present invention, the function of the pressure reducing valve 1 is to receive the compressed gas at a relatively high pressure from the air inlet line (i.e., the pressure reducing valve air inlet pipe 12), stabilize it within a preset safe low pressure range, and then deliver it to the liquid storage tank 2. This design can ensure that the liquid storage tank 2 will not be damaged due to excessive gas pressure, while maintaining sufficient pressure so that under the control of the solenoid valve 3, the cleaning liquid can be effectively pushed to the position of the wiping pad (e.g., wool felt).

[0067] It should be noted that, for the present invention, the liquid storage device 2 can be used to store the cleaning liquid 23, and the cleaning liquid 23 is delivered by air pressure. The solenoid valve 3, as an intelligent control element, can be connected to an external control system to open or close the on-off of the cleaning liquid (cleaning liquid 23) according to a set program, thereby wetting the wiping pad (such as wool felt), increasing the cleaning ability of the wiping pad (such as wool felt), and realizing automatic operation. The solenoid valve 3 is a common valve in the prior art, and its control technology is a conventional technology known in the prior art, which will not be described in detail here.

[0068] It should be noted that, for the utility model, the wiping and cleaning device 5 is used to support and protect the pole ear during the transportation process. The design of the wiping pad can prevent the pole ear from being damaged by direct contact with hard materials. At the same time, the softness of the wiping pad helps to absorb and store tiny particles.

[0069] In the present invention, the wiping cleaning device 5 is a special wiping tool made of high-quality wool felt material. This structure has the following characteristics:

[0070] 1. Material characteristics: Made of pure wool with high purity, fineness and no impurities, it ensures that the wool felt has excellent moisture absorption and adsorption, and can effectively remove particles and stains attached to the surface of the tab.

[0071] 2. Stable positioning: There are grooves on both the upper and lower sides of the supporting device, which can ensure the stability of the wool felt during the wiping process and will not scratch the surface of the tab, avoiding deviation or skew.

[0072] 3. Efficient cleaning: By closing the upper support structure (i.e., the first wiping pad support block 53), the upper and lower wool felt end faces can be aligned, so that the tabs are completely clamped in the middle and in contact with the wool felt at both ends. The upper surface of the support structure (i.e., the first wiping pad support block 53) is also provided with a through hole to cooperate with the flow regulating valve of the liquid guide tube, which can provide an appropriate amount of cleaning liquid (i.e., cleaning liquid 23) to the wool felt for wetting. In this way, after the upper wool felt is wetted, the cleaning liquid will gradually penetrate into the lower wool felt, thereby improving the effectiveness of the entire cleaning process.

[0073] 4. Durability and safety: Wool felt itself is a material that is resistant to friction, not easy to deform, and has good chemical stability, which ensures that it can maintain a good cleaning effect after repeated use. It is also safer for many metal surfaces and will not cause chemical reactions.

[0074] In the present utility model, the specific implementation is as follows: Figure 3 As shown, the blowing device 6 comprises: a blowing nozzle 65;

[0075] The air inlet on one side of the air blowing nozzle 65 is connected to one end of the air inlet pipe 61 of the air blowing device through the air pressure regulating valve 64;

[0076] The other end of the air inlet pipe 61 of the blowing device is connected to the air outlet of an external air source (such as a compressed gas cylinder);

[0077] The blowing port on the other side of the blowing nozzle 65 is arranged corresponding to the battery tab 4, that is, a high-pressure airflow is blown toward the battery tab.

[0078] It should be noted that, for the present invention, the air pressure regulating valve 64 is located at the air source inlet of the entire device, and is used to accurately control the pressure of the compressed air entering the blowing device 6 to ensure that the blowing force is moderate. The blowing device 6 uses high-pressure gas to quickly and efficiently clean the passing tabs.

[0079] In the present utility model, the specific implementation is as follows: Figure 3 As shown, the novel battery tab cleaning device further includes a tab embossing device 7, which is used to perform embossing treatment (i.e., pressing out a protrusion on the battery tab 4, such as pressing out a strip-shaped protrusion) on the battery tab 4 after being wiped (i.e., cleaned) by the wiping cleaning device 5;

[0080] In specific implementation, the tab embossing device 7 includes: a tab embossing base 70;

[0081] The top of the tab embossing base 70 is provided with a tab embossing die 71;

[0082] A tab embossing convex die 72 is provided directly above the tab embossing concave die 71;

[0083] The battery tab 4 is located between the tab embossing die 71 and the tab embossing convex die 72 .

[0084] Furthermore, the tab embossing convex die 72 is connected to the drive output end at the lower part of the vertically distributed cylinder 62;

[0085] The cylinder 62 is fixedly provided with one side of a vertically distributed cylinder fixing plate 63;

[0086] Furthermore, the lower end of the cylinder fixing plate 63 is fixedly connected to the tab embossing base 70;

[0087] The cylinder fixing plate 63 is provided with a ventilation notch at a position corresponding to the blowing port on the blowing nozzle 65, for allowing the high-pressure airflow blown out of the blowing port of the blowing nozzle 65 to pass through and blow onto the surface of the battery tab 4 (and also blow onto the surface of the tab embossing die 71 and the tab embossing convex die 72).

[0088] Furthermore, the cylinder fixing plate 63 is provided with a first cylinder fixing plate floating hole position 631 and a second cylinder fixing plate floating hole position 632 which are spaced apart from each other in the upper and lower parts;

[0089] The cylinder fixing plate 63 is used to be threadedly connected with the screw hole reserved on the shell of the cylinder 62 by means of a screw passing through the floating hole position 631 of the first cylinder fixing plate or the floating hole position 632 of the second cylinder fixing plate.

[0090] It should be noted that, for the present invention, the tab embossing device 7, which is located immediately after the blowing device 6, is responsible for embossing the cleaned tab (i.e., pressing a plurality of protrusions on the battery tab) to ensure the stability and reliability of subsequent welding or other processes.

[0091] It should be noted that, for the utility model, the blowing device 6 is installed below the cylinder fixing plate 63 through the reserved bolt holes. The floating hole design on the cylinder fixing plate 63 can realize the precise fine-tuning of the upper and lower positions of the cylinder 62, ensuring that the airflow blown by the blowing device 6 can accurately act on the working surface of the tab and the embossing tooling (i.e., the tab embossing device 7), wherein the air source interface of the blowing device 6 is connected to the external compressed air source; the gas channel (the blowing device air inlet pipe 61) is responsible for guiding and transmitting the high-pressure airflow; the blowing nozzle 65 is designed into a specific shape and angle as needed to ensure that the airflow can accurately blow to the tab and the embossing tooling surface, effectively remove impurities, ensure the cleaning quality, and also achieve a good drying effect.

[0092] According to actual needs, the air pressure regulating valve 64 can be used to control the air flow size and switch to ensure that the air flow exerts a moderate and stable force on the tabs and embossing tooling.

[0093] In the present utility model, the specific implementation is as follows: Figure 3 As shown, the dust collecting device 8 comprises: a hollow dust collecting hood 82;

[0094] The dust cover 82 is arranged correspondingly to the air blowing device 6;

[0095] The battery tab 4 is located between the dust hood 82 and the blowing device 6 .

[0096] In a specific implementation, the dust suction port 820 on one side of the dust suction cover 82 faces the battery terminal lug 4 .

[0097] The air outlet on the other side of the dust hood 82 is connected to one end of the dust collection duct 81;

[0098] The other end of the dust collection pipe 81 is connected to the dust collection inlet of an external dust collection device (such as a vacuum cleaner).

[0099] In specific implementation, the dust suction port 820 on one side of the dust suction cover 82 is in the shape of a square;

[0100] The air outlet on the other side of the dust cover 82 is circular in shape.

[0101] It should be noted that the vacuuming device is, for example, a commonly used vacuum cleaner, which will not be described in detail here.

[0102] It should be noted that, for the utility model, the dust suction device 8 is arranged on the opposite side of the blowing device 6, and is used to collect and remove dust and debris generated by the blowing cleaning process in real time, keep the inside of the equipment clean, improve the product quality of the battery tabs, and extend the service life of related battery production equipment.

[0103] It should be noted that, for the present invention, the dust suction device is a structure that combines a cylindrical shape and a square opening (i.e., the dust suction port 820), and a square opening (i.e., the dust suction port 820) is provided at one end. The square opening is precisely installed opposite to the air blowing device 6, and this layout cleverly ensures that all the tiny particles such as plastic scraps and dust generated during the cleaning of the tab can directly enter the square opening (i.e., the dust suction port 820).

[0104] The circular opening (i.e., the air outlet on the other side of the dust cover 82) serves as a channel interface for the dust collection pipe 81 and is closely connected to an external dust collection system (such as a vacuum cleaner). When the tab passes through the air blowing device, the impurities generated are instantly sucked into the circular opening by the strong suction force and quickly discharged through the dust collection pipe, thereby achieving the purpose of instantly removing pollutants and keeping the tab surface clean.

[0105] In the present invention, it should be noted that the present invention can play the following functions:

[0106] 1. Reduce physical contact: In order to prevent secondary contamination or scratching of the tab during the cleaning process, the cleaning device (i.e., the wiping cleaning device 5) uses wool felt made of soft material to gently wipe the surface of the tab.

[0107] 2. Efficient dust removal and cleaning: The air blowing device can use air blowing technology to effectively remove dust and particles on the surface of the tabs and embossing tooling, as well as plastic scraps or other impurities that may be generated during the production process. The dust suction device 8 collects foreign matter blown off from the tab embossing position through the connected dust suction pipe, which helps to improve the quality of the battery, ensure a good production environment, and ensure the health of the staff.

[0108] 3. Precisely control the wetness: Equipped with a humidity control unit (i.e., including a solenoid valve 3 and a liquid storage device 2), the wiping pad (e.g., wool felt) is moistened through the solenoid valve to increase the cleaning ability of the wiping pad (e.g., wool felt), thereby further ensuring that there is no excess liquid on the surface of the tab and that it is not too dry, thereby helping to avoid affecting subsequent welding effects and battery performance due to improper wetness.

[0109] Compared with the prior art, the tab cleaning device provided by the utility model is mainly used for efficiently and accurately cleaning the tabs of the battery cell in the battery manufacturing process, and the beneficial effects produced are as follows:

[0110] 1. Improve electrical contact performance: By removing dirt, residual electrolyte, metal chips and other impurities on the surface of the pole ear, ensure good electrical contact between the pole ear and the current collector or external connector, reduce resistance and heat generation, and improve the energy efficiency and charge and discharge performance of the battery.

[0111] 2. Prevent short circuit risks: Effectively remove tiny particle pollutants that may cause internal short circuits, enhance battery safety, and reduce the risk of thermal runaway caused by short circuits.

[0112] 3. Extend battery life: Fine cleaning can prevent impurities from corroding the tab material, reduce potential electrochemical instability factors, help maintain long-term stable operation of the battery, and extend battery life.

[0113] 4. Improve production yield: The tab cleaning device provided by the utility model can standardize the operation process and ensure the consistency of the cleaning quality of each tab, thereby improving the overall battery production yield.

[0114] 5. Comply with environmental protection requirements: The utility model is a professional cleaning device, which can usually collect waste materials in the cleaning process more effectively, reduce environmental pollution, and meet the environmental protection standards of modern industrial production.

[0115] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
