Abstract: An infiltration device comprises a heating room, a rotary tray, a rotary bracket, a material box, an elevating mechanism and a transmission device, wherein the heating room has an annular groove, and the rotary tray is arranged below an opening end at a lower end of the heating room; the rotary bracket is installed on the rotary tray; the material box is arranged on the rotary bracket; the rotary tray and the material box can move upward and downward under the action of the elevating mechanism; the rotary bracket can spin in the annular groove and revolve around a central axis of the rotary tray under the action of the transmission device. The infiltration method provided by the invention comprises the steps of charging, vacuum-pumping, high temperature infiltrating, cooling, discharging, etc.

Abstract: A spraying device comprises: a conveyer comprising a mesh crawler belt configured to carry an object to be sprayed; a baking chamber for heating the object to be sprayed; a spraying chamber having at least one atomizing nozzle disposed within the spraying chamber, the atomizing nozzle being configured to uniformly spray a coating solution on a surface of the object to be sprayed; a cleaning chamber for cleaning the mesh crawler belt and recycling the coating solution carried by the mesh crawler belt; and a solution storage apparatus for storing the coating solution that the spraying chamber needs for spraying; wherein the mesh crawler belt passes successively through the baking chamber, the spraying chamber and the cleaning chamber. The device of the present invention can ensure uniformity of the thickness of a coating layer on the magnet. In addition, the device can improve spraying efficiency and save raw material.
