[0002] A pole piece drying system for the coating process of lithium-ion batteries mainly dries the battery pole pieces evenly through heating and air circulation. This system ensures that the solvent in the coated pole pieces is completely volatilized and dried by precisely controlling the hot air distribution and temperature, so as to improve the performance and safety of the battery. The drying process can also adapt to different specifications of pole pieces by adjusting the wind speed and temperature to optimize the production efficiency.

[0003] In actual work, the existing pole piece drying system for the coating process of lithium-ion batteries can dry the pole pieces through a heating system, but there are still the following problems:

[0004] At present, most pole piece drying systems use heating plates directly facing the pole pieces for drying, but this method has many deficiencies. The inaccurate temperature control is likely to cause overheating, damage the quality of the pole pieces, and affect the battery performance. In addition, the heat is not discharged smoothly after drying, the equipment runs at a high temperature for a long time, the service life is shortened, the failure rate is increased, and the residual heat will also cause the working environment temperature to rise, affecting the safety of operators. Summary of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figure 1 - Figure 3 shown, this embodiment provides a technical solution: a drying system for electrode sheets in the lithium-ion battery coating process, including a bottom plate 1, a heating box 4 is arranged on the bottom plate 1, and a circulation component 6 is arranged on the heating box 4;

[0025] The circulation component 6 includes a heat collection box I 61. A delivery pipe I 62 is arranged on the side of the heat collection box I 61 away from the delivery pipe III 66. The other end of the delivery pipe I 62 is provided with a blowing box 63. Heating fans 64 are arranged in the blowing box 63. A delivery pipe IV 68 is arranged on the side of the heat collection box I 61 close to the delivery pipe IV 68. A delivery pipe II 65 is arranged on the other side of the heat collection box I 61. Through the heating layer 9, the inside of the box can be evenly heated. The design of the annular plate 8 optimizes the heat diffusion process, ensures uniform temperature distribution, and effectively avoids the risk of damage to the electrode sheet due to local overheating. In addition, the delivery pipe II 65 effectively transfers the heat generated by the heating layer 9 into the heat collection box I 61, and then sends the heat to the blowing box 63 through the delivery pipe I 62. In the blowing box 63, the function of the heating fan 64 is to evenly deliver the hot air into the inside of the box, thereby maintaining the stability of the internal temperature. This process not only improves the heating efficiency but also prevents the internal temperature of the box from being too high, solving the technical problem of damage to the electrode sheet caused by directly heating the electrode sheet.

[0026] Even further, as Figure 1 - Figure 3As shown in the figure: On one side of the heat collection box 1 (61), there is a third conveying pipe 66. On the other side of the third conveying pipe 66, there is a second heat collection box 67. Through the third conveying pipe 66, the excess heat in the first heat collection box 61 can be transferred to the second heat collection box 67. At the same time, the second conveying pipe 65 will also guide part of the heat generated by the heating layer 9 to the second heat collection box 67, which not only improves the heating efficiency of the overall system but also provides convenience for subsequent heat dissipation treatment, ensuring the temperature balance and stability of the entire system.

[0027] The above equipment cannot exclude the internal temperature. For example, Figure 3 As shown in the figure: In this solution, a heat dissipation component 7 is provided at the top of the second heat collection box 67. The heat dissipation component 7 includes a connection box 71. At the top of the connection box 71, there is a connection pipe 72. At the other end of the connection pipe 72, there is an exhaust fan 73. Through the designed connection box 71, the system can efficiently transfer the heat inside the second heat collection box 67 to the connection pipe 72. Subsequently, the exhaust fan 73 plays a role and effectively discharges the heat in the connection box 71 and the connection pipe 72 outside the system. This process not only helps maintain the temperature balance inside the equipment but also prevents potential damage to the equipment caused by excessive temperature, ensuring the stable operation of the entire system.

[0028] Working principle: As Figures 1 - 4 shown,

[0029] In use: First, the conveyor belt 3 steadily feeds the materials into the heating box 4, and the support legs 2 can support the equipment. At this time, the heating layer 9 starts to function, heating the inside of the box to achieve the drying effect of the materials. The design of the annular plate 8 further optimizes the heat diffusion process, ensuring uniform temperature distribution inside the box and avoiding the risk of damage to the electrode due to local overheating. To make more efficient use and management of thermal energy, the temperature inside the equipment can be adjusted through the control panel 5. The conveying pipe two 65 transports the heat generated by the heating layer 9 to the heat receiving box one 61, and the conveying pipe one 62 further transports this heat to the blowing box 63. In the blowing box 63, the heating fan 64 evenly sends the hot air into the inside of the box, thereby maintaining the stability of the internal temperature and promoting the material drying process. As the heat continuously circulates, a part of the excess heat is transferred to the heat receiving box two 67 through the conveying pipe three 66. At the same time, the conveying pipe two 65 also guides a part of the heat on the heating layer 9 here for subsequent heat dissipation treatment. This process not only improves the heating efficiency of the overall system but also provides convenience for subsequent heat dissipation treatment, ensuring the temperature balance and stability of the entire system. To ensure the long-term stable operation of the equipment and prevent damage caused by excessive internal temperature, the connecting box 71 transports the heat inside the heat receiving box two 67 into the connecting pipe 72. Subsequently, the exhaust fan 73 functions to effectively discharge the heat in the connecting box 71 and the connecting pipe 72 out of the system. In addition, the design of the anti-damage shell 610 and the dust-proof box 69 also reflects the consideration for the safety of operators and equipment maintenance. These components can prevent personnel from accidentally touching the high-temperature parts during operation or maintenance, thus avoiding possible injuries. At the same time, they can also prevent dust and foreign objects from entering the system, affecting the normal operation and service life of the equipment.

[0030] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
