Drying device, drying system and battery production system

The utility model relates to a drying device, a drying system and a battery production system, a magnetic induction mechanism is arranged in a drying oven, and a current collector is heated in a magnetic induction heating mode. Meanwhile, the air inlet component is arranged on the drying oven, hot airflow can be provided for the interior of the drying oven through the air inlet component, and the current collector is heated in a hot air blow-drying mode. In this way, hot air blow-drying and magnetic induction heating are combined, and the drying effect of the surface of the current collector is improved. Due to the fact that the air inlet component is communicated with the cavity, entering airflow firstly enters the cavity and then is dispersed into the drying channel through the air holes, the blowing probability of the airflow to the local position of the current collector is reduced, and the drying range is expanded. In addition, the magnetic induction heating mode has the characteristic of uniformly generating heat for the current collector, so that the drying device can effectively improve the drying uniformity and the drying effect.
