Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery electrode processing technology, specifically a lithium-ion battery electrode coating machine. Background Technology
[0002] Battery electrodes typically refer to the positive and negative electrodes in a battery. These electrodes are isolated from each other by an electrolyte, forming a closed circuit. The positive electrode is usually composed of oxides or other compounds, while the negative electrode is typically composed of metals or carbon materials. During charging and discharging, chemical reactions occur between the positive and negative electrodes, releasing or absorbing charge and generating electrical energy. In the processing of lithium-ion battery electrodes, surface coating treatment is required. The "Lithium-ion Battery Electrode Coating Machine" disclosed in publication number "CN210700857U" has solved the problem of lacking suitable... While addressing the technical drawbacks of high-solids-content slurry lithium-ion battery electrode coating machines, similar machines still have numerous shortcomings in practical use. For example, they lack the function of cleaning and disinfecting the electrode surface before coating. If there are contaminants such as oil, dust, or oxide layers on the battery electrode surface, these contaminants may be mixed into the electrode material during the coating process. This could not only cause micro-short circuits inside the battery but also lead to more serious safety issues such as thermal runaway and fire. To address these issues, we have designed a lithium-ion battery electrode coating machine. Utility Model Content

[0026] Please see Figure 1-7This utility model provides a technical solution: a lithium-ion battery electrode coating machine, including a main unit 1 and a feeding mechanism 4 and a drying mechanism 3 arranged in a front-to-back configuration inside the main unit 1, and a cleaning mechanism 2 assembled in the center of the main unit 1. The main unit 1 includes a mounting cabinet 101 and a drying mechanism 3. A base 102 is fixedly installed at the bottom of the mounting cabinet 101, and a protective cover 7 is fixedly installed on the front of the mounting cabinet 101. An observation window 703 is fixedly installed on the upper part of the front of the protective cover 7. The feeding mechanism 4 includes a feeding assembly seat 401, and a feeding rack 402 is fixedly installed on the top of the feeding assembly seat 401. An adjusting push rod 403 is fixedly installed on the upper part inside the feeding rack 402, and an adjusting frame 404 is fixedly installed at the output end of the adjusting push rod 403. Feeding wheels 406 are rotatably installed inside both the feeding rack 402 and the adjusting frame 404. The front of both the feeding rack 402 and the adjusting frame 404 are fixed. The feeding motor 405 is installed with its output end connected to the feeding wheel 406. The cleaning mechanism 2 includes a slide 201, a storage seat 5, and a coating seat 6. A slider 202 is slidably installed inside the slide 201. A cleaning frame 203 is fixedly installed on the front of the slider 202. A cleaning cotton 204 is fixedly installed on the top inside the cleaning frame 203. An alcohol tank 501 is fixedly installed inside the storage seat 5. An alcohol pump 502 is fixedly installed on the front inside the storage seat 5. A liquid guide tube 207 is fixedly connected to the output end of the alcohol pump 502. A fixing plate 601 is fixedly installed on the back of the coating seat 6. An organic head 602 is fixedly installed on the bottom of the coating seat 6. The drying mechanism 3 includes a drying box 301. An inlet ring 302 and an outlet ring 303 are fixedly installed on both sides of the drying box 301. Multiple sets of drying pipes 305 are fixedly installed on the bottom and bottom of the drying box 301. Two sets of drying seats 307 are fixedly installed on the bottom of the drying box 301.
[0027] Based on the above structural configuration, the lithium-ion battery electrode coating machine consists of a main unit 1, a feeding mechanism 4, a drying mechanism 3, and a cleaning mechanism 2. The main unit 1 serves as the overall support and mounting mechanism for the coating machine. The feeding mechanism 4 is an automatic feeding mechanism for the coating machine during operation. The cleaning mechanism 2 is a cleaning mechanism for the battery electrodes, cleaning the surface of the electrodes before coating. The drying mechanism 3 dries the coated electrodes. Specifically, during operation, the feeding rack 402 is fixedly mounted on the front of the mounting cabinet 101 via the feeding assembly base 401. On one side, the feeding rack 402 and the feeding wheel 406 inside the adjusting rack 404 rotate to automatically feed the battery electrode sheets during coating machine operation. The adjusting push rod 403 can adjust the height of the feeding rack 402 and the feeding wheel 406 inside, thereby adjusting the tightness of the battery electrode sheets during feeding. The feeding motor 405 can drive the feeding wheel 406 to rotate. The cleaning rack 203 and the internal cleaning cotton 204 can clean the surface of the battery electrode sheets entering the coating machine, ensuring the cleanliness of the surface during coating. The clean electrode surface ensures the smooth progress of the coating process, allowing the slurry to be evenly coated on the electrode sheets, thereby improving battery performance. For safety, the storage seat 5 is fixedly installed on the top of the mounting cabinet 101. The storage seat 5 secures the alcohol tank 501. The alcohol pump 502 can draw alcohol from the inside of the alcohol tank 501. The liquid guide tube 207 can guide the alcohol drawn by the alcohol pump 502 into the cleaning cotton 204, thereby cleaning the surface of the battery electrode with alcohol. Alcohol can remove oil, dust, light oxidation layer and other contaminants from the surface of the electrode, providing a good foundation for the subsequent coating process. The clean electrode surface helps the slurry to be coated evenly, improving the performance and safety of the battery. The coating seat 6 is fixedly installed on the front of the mounting cabinet 101 by the fixing plate 601. At the central position, the coating seat 6 and the machine head 602 can coat the cleaned electrode surface. After coating, the electrode enters the drying chamber 301 through the inlet ring 302. The drying tube 305 can dry the coated electrode inside the drying chamber 301. The discharge ring 303 can discharge the dried battery electrode, which is convenient for subsequent equipment to continue processing the battery electrode. The drying seat 307 can be installed and supported when the drying chamber 301 is in operation. The protective cover 7 can close and protect the outside of the coating machine during operation, increasing the stability of the coating machine during operation. The observation window 703 allows the operator to observe the inside of the coating machine during operation.
[0028] Furthermore, an operation button 105 is fixedly installed on the upper side of one side of the mounting cabinet 101, and a display screen 106 is fixedly installed above the operation button 105. Both the operation button 105 and the display screen 106 are connected to the control system of the coating machine via wires. The operator can operate the coating machine through the operation button 105, and the operator can view the status of the coating machine during operation by viewing the data displayed on the display screen 106.
[0029] Furthermore, a threaded shaft 208 is threadedly mounted on the top of the slide 201, and a handwheel 209 is fixedly mounted on the top of the threaded shaft 208. By rotating the threaded shaft 208, the slider 202 and the cleaning rack 203 can be adjusted up and down, thereby adjusting the cleaning height of the battery terminals. The handwheel 209 facilitates operation by staff when rotating the threaded shaft 208.
[0030] Furthermore, a liquid distribution tube 205 is fixedly installed on the top of the cleaning cotton 204, and a spring tube 206 is fixedly connected to the liquid guide tube 207. The liquid distribution tube 205 can evenly inject the alcohol conducted by the liquid guide tube 207 into the cleaning cotton 204, and the spring tube 206 can elastically extend the working length of the liquid guide tube 207.
[0031] Furthermore, a maintenance door panel 701 is movably installed on the front of the protective cover 7, and two sets of pull rings 702 are fixedly installed on the lower front of the maintenance door panel 701. The maintenance door panel 701 facilitates the later inspection and maintenance of the coating interior by the staff, and the pull rings 702 facilitate the operation of the staff when opening the maintenance door panel 701.
[0032] Furthermore, the bottom of the base 102 is threaded with multiple sets of threaded support legs 104, and the bottom of the threaded support legs 104 is rotatably mounted with foot plates 103. The threaded support legs 104 can support the bottom of the base 102, and the foot plates 103 increase the force-bearing area at the bottom of the threaded support legs 104, thereby improving the stability when supporting the coating machine.
[0033] Furthermore, two sets of protective nets 304 are fixedly installed in the center of the drying chamber 301, and reflectors 306 are fixedly installed on the top and bottom of the inner wall of the drying chamber 301. The protective nets 304 can isolate and protect the battery electrodes during drying, and the reflectors 306 can reflect heat, thereby improving the drying efficiency of the drying tube 305 in drying the battery electrodes.
