[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example

[0031] like Figure 1-5 As shown, an embodiment of the present invention provides a battery cell coating and drying device, including a drying device 1. A battery cell coating machine 2 is provided on one side of the drying device 1. After the battery cell is coated by the battery cell coating machine 2, it flows directly into the interior of the drying device 1 for drying. The drying device 1 includes a drying production line 11. A heating cover 12 is provided on the drying production line 11. A heating cover 12 is provided on the top of the heating cover 12.

[0032] The heating cover 12 is provided with two air guide covers 15 inside. The air guide covers 15 are connected to the heating device 13 through a rubber sleeve 14. The heating cover 12 is also provided with an adjusting screw 17 for adjusting the relative position of the two air guide covers 15.

[0033] like Figure 1-5 As shown, in some embodiments, an air suction hood 151 is provided on the outer bottom of the air guide hood 15, and the two air guide hoods 15 and the two air suction hoods 151 are movably connected by a thinning portion 152 and a slot 153.

[0034] The thinning portion 152 makes the connection part thinner, which facilitates the docking of the slot 153. The slot 153 is designed to allow the air guide shroud 15 and the suction shroud 151 to remain connected when they move relative to each other, thereby adapting to position adjustment. This movable plug-in structure allows the air guide shroud 15 and the suction shroud 151 to be adjusted according to the width of the battery cell, ensuring uniform hot air blowing and effective exhaust gas extraction, improving drying uniformity and efficiency, while reducing energy waste.

[0035] like Figure 1-5 As shown, in some embodiments, the rubber sleeve 14 has an inner extension sleeve 141 extending to the bottom of the inner side of the two air guide shrouds 15, and the two sides of the inner extension sleeve 141 are fixedly connected to the inner side of the two air guide shrouds 15 respectively.

[0036] The inner extension sleeve 141 serves as a flexible sealing component, extending or contracting as the air guide shroud 15 moves to maintain internal communication. The inner extension sleeve 141 provides a dynamic seal between the inner sides of the two air guide shrouds 15, preventing hot air leakage and ensuring that hot air is concentrated on the battery cells, thereby improving thermal energy utilization and drying effect.

[0037] like Figure 1-5 As shown, in some embodiments, the rubber sleeve 14 is provided with an outer extension sleeve 142 extending to the bottom of the outer side of the two suction hoods 151. The two sides of the outer extension sleeve 142 are fixedly connected to the outer sides of the two air guide hoods 15 and the suction hoods 151, respectively.

[0038] The outer extension sleeve 142 covers the outside and deforms as the air guide hood 15 and the suction hood 151 move. The outer extension sleeve 142 seals the outside of the suction hood 151 to prevent external air interference or internal exhaust gas from escaping, maintain the stability of the drying environment, and reduce heat loss and environmental pollution.

[0039] like Figure 1-5 As shown, in some embodiments, the heating device 13 includes a housing 131 disposed on the top of the heating cover 12, at least one air inlet fan 132 is disposed on the top of the housing 131, and a plurality of heating tubes 133 are disposed inside the housing 131.

[0040] The air intake fan 132 introduces external air, and the heating tube 133 heats the air before it is conveyed through the air guide shroud 15. The air intake fan 132 provides a continuous airflow, and the heating tube 133 generates uniform hot air, ensuring stable temperature during the drying process, improving drying speed and cell quality, and adapting to different production rhythms.

[0041] like Figure 1-5 As shown, in some embodiments, the adjusting screw 17 is provided with two sections of threads running in opposite directions, and the interiors of the two air guide covers 15 are respectively connected to the two sections of threads on the adjusting screw 17 through nut seats.

[0042] When the adjusting screw 17 rotates, the two air guides 15 move synchronously in opposite directions. This design allows the two air guides 15 to be adjusted symmetrically, quickly adapting to battery cells of different widths, ensuring that hot air covers the entire surface of the battery cells, and improving drying uniformity and operational flexibility.

[0043] like Figure 1-5 As shown, in some embodiments, at least two stabilizing rods 16 are also provided inside the heating cover 12, and the two air guide covers 15 are slidably sleeved with the two stabilizing rods 16.

[0044] The stabilizer bar 16 is fixed inside the heating cover 12 to provide linear guidance for the air guide cover 15. The stabilizer bar 16 enhances the stability of the air guide cover 15 when it moves, prevents deviation or vibration, and ensures that the hot air blowing direction is accurate.

[0045] like Figure 1-5 As shown, in some embodiments, at least one heating roller 18 is also provided inside the drying production line 11, and a drive box 111 is provided on one side of the drying production line 11. A conductive seat 114 is provided inside the drive box 111, and one end of the heating roller 18 extends into the interior of the drive box 111 and is movably connected to the conductive seat 114 through a conductive slip ring.

[0046] The heating roller 18 integrates an electric heating tube 133. The heating roller 18 continuously receives power during rotation through a conductive slip ring. The heating roller 18 provides direct contact heating, which complements hot air drying and is responsible for drying the bottom and top of the battery cells respectively, thus accelerating the drying of the battery cells. The conductive slip ring ensures that the heating roller 18 is stably powered during rotation, enabling continuous production and improving overall efficiency.

[0047] like Figure 1-5 As shown, in some embodiments, a motor 112 is provided on one side of the drive box 111, and the output end of the motor 112 is connected to the heating roller 18 via a transmission chain 113.

[0048] The output end of the motor 112 and the heating tube 133 are provided with a gear shaft that meshes with the transmission chain 113. The motor 112 drives the transmission chain 113 to rotate the heating roller 18. The motor 112 and the transmission chain 113 realize the automatic rotation of the heating roller 18, so that the battery cells move smoothly during the drying process and reduce manual intervention.

[0049] like Figure 1-5As shown, in some embodiments, an air outlet hood 19 is provided on one side of the heating cover 12, and a suction fan 192 is provided inside the air outlet hood 19. A suction seat 193 is provided on one side of the air outlet hood 19, with one end extending into the interior of the heating cover 12. The suction seat 193 is connected to two suction covers 151 through a plurality of suction pipes 194. An exhaust connector 191 is provided on the top of the air outlet hood 19.

[0050] The suction fan 192 draws exhaust gas from the suction hood 151 through the suction pipe 194 and discharges it centrally through the exhaust connector 191. The exhaust connector 191 is connected to the workshop exhaust gas pipeline. The suction fan 192 removes the humid and hot air after drying in a timely manner, prevents the accumulation of exhaust gas, and keeps the working environment clean and safe. Centralized discharge reduces pollution and helps maintain a stable temperature in the drying room.

[0051] In summary, the symmetrically adjustable air guide shroud 15 can quickly adapt to battery cells of different widths, ensuring that hot air evenly covers their surfaces. The suction shroud 151, in conjunction with the suction fan 192, can directly and quickly extract and centrally discharge the exhaust gas generated during the drying process, effectively maintaining a stable and clean environment inside the drying chamber. At the same time, the heating roller 18 provides contact heating to the bottom of the battery cells, complementing the hot air drying at the top, forming a highly efficient double-sided drying structure that significantly improves drying efficiency and quality while reducing overall energy consumption.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
