[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] Please see Figure 1 The preferred embodiment of this utility model provides an electromagnetic heating degreasing device, including a frame 1 and a nozzle assembly 2, a fan assembly 3 and several rollers 4, all mounted on the frame 1. The nozzle assembly 2 is used to heat the aluminum foil and blow air onto the aluminum foil, the fan assembly 3 is used to blow air onto the aluminum foil to disperse the grease on the aluminum foil and perform exhaust recovery, and the rollers 4 are used to transport the aluminum foil.

[0025] For details, please see Figure 1-3 The nozzle assembly 2 is located between two adjacent rollers 4, and the fan assembly 3 is located on the air outlet side of the nozzle assembly 2. The nozzle assembly 2 includes a nozzle housing 21 and an electromagnetic heating plate 22. The electromagnetic heating plate 22 is located inside the nozzle housing 21. The aluminum foil is conveyed between the rollers 4. Since the nozzle assembly 2 is located between two adjacent rollers 4, the aluminum foil can pass over the surface of the nozzle housing 21. The nozzle housing 21 can disperse the oil film on the surface of the aluminum foil. The electromagnetic heating plate 22 inside can quickly preheat the aluminum foil and accelerate the evaporation of the oil film. The electromagnetic heating heats up quickly and can meet the requirements of high-speed conveyor belt. In addition, the eddy currents caused by electromagnetic heating can effectively improve the dyne value of the aluminum foil. Increasing the dyne value can help improve the adhesion of subsequent coatings and enhance the yield of battery products. Meanwhile, on the air outlet side of the nozzle assembly 2, the fan assembly 3 can blow air to the other side of the aluminum foil to disperse the oil film on that side, achieving double-sided degreasing of the aluminum foil. Furthermore, the fan assembly 3 can also extract and recover the volatile oil film, preventing it from being directly discharged into the air, which is beneficial to environmental protection.

[0026] Please see Figure 1 The blower assembly 3 includes a blower 31 and two suction components 32. The blower 31 is used to blow air onto the aluminum foil, and the suction components 32 are used to extract and recover the air. The blower 31 is located between the two suction components 32. The nozzle assembly 2 is provided with three nozzles. The three nozzle assemblies 2 are respectively arranged opposite to the blower 31 and the two suction components 32. The suction components 32 can promptly remove the energy diffused during blowing, which is beneficial to maintaining the stability of the airflow direction. Furthermore, the suction components 32, the blower 31, and the nozzle assembly 2 operate synchronously. The suction components 32 can quickly capture the volatile oil film and prevent excessive evaporation of the oil film into the air.

[0027] Please see Figure 3 The electromagnetic heating plate 22 includes a coil support 221 and an electromagnetic coil (not shown in the figure). The coil support 221 is equipped with a baffle 222 and several support plates 223. The baffle 222 is located outside the support plates 223. Each support plate 223 has a groove 224 on one side. The electromagnetic coil is wound around the support plate 223 through the grooves 224. A limiting groove 225 is provided on the side of the baffle 222 facing the support plate 223, and the bend of the electromagnetic coil is located within the limiting groove 225. The groove 224 facilitates the fixing of the electromagnetic coil, prevents coil misalignment, avoids wire displacement due to insufficient tension, and ensures neat and uniform winding. The bend of the electromagnetic coil located within the limiting groove 225 prevents the accumulation of magnetic induction lines at both ends. Magnetic induction accumulation can cause overheating, leading to oil film carbonization and blackening, damaging the aluminum foil.

[0028] In this embodiment, a through hole 226 is provided at the bottom of the groove 224, extending to the bottom surface of the support plate 223 opposite to the groove 224. A plurality of vent holes 227 are provided on the baffle 222. The through hole 226 and vent holes 227 facilitate heat dissipation of the electromagnetic coil in both horizontal and vertical directions, preventing the electromagnetic coil from overheating and increasing its resistance, thus reducing heating efficiency. Furthermore, a temperature sensor (not shown in the figure) is provided inside the electromagnetic heating plate 22 for real-time temperature monitoring to prevent overheating and equipment damage.

[0029] Please see Figure 4 The nozzle housing 21 is provided with a first guide plate 211 and a second guide plate 212. The first guide plate 211 and the second guide plate 212 are opposite to each other and spaced apart. Both are perforated plates, and the mesh on the second guide plate 212 is connected to the through hole 226. The electromagnetic heating plate 22 is disposed on the second guide plate 212 and the two are connected. The first guide plate 211 and the second guide plate 212 are used to optimize the airflow direction and improve the uniformity of the airflow. In addition, part of the airflow is heated by the electromagnetic heating plate 22 and then output to improve the oil removal effect.

[0030] The nozzle housing 21 also has two side plates 213 connected to the second guide plate 212. The electromagnetic heating plate 22 is located between the two side plates 213. A slit air outlet channel 214 is formed between the side plates 213, the second guide plate 212, and the side wall of the nozzle housing 21. The side wall of the nozzle housing 21 near its air outlet side is provided with a slit air outlet 215 and an electromagnetic heat dissipation port 216. The slit air outlet 215 is connected to the slit air outlet channel 214, and the electromagnetic heat dissipation port 216 is connected to the electromagnetic heating plate 22. The slit air outlet channel 214 can increase the air velocity. The high-speed air output through the slit air outlet 215 can smooth out the wrinkles caused by electromagnetic heating and effectively disperse the oil film. The electromagnetic heat dissipation port 216 is used for heat dissipation of the entire electromagnetic heating plate 22 to prevent the temperature from being too high and reducing its lifespan.

[0031] In this embodiment, the second guide plate 212 is provided with a bending portion 217 on the side near the slit air outlet channel 214. The bending portion 217 is fixedly connected to the side wall of the nozzle housing 21. The bending portion 217 is used to provide support so that the second guide plate 212 can be fixed to the nozzle housing 21 by riveting or welding.
