The invention provides a coating and polymerization device of a chip solid capacitor core. The coating and polymerization device comprises a machine stand adjusting mechanism, a lifting control mechanism, adjusting mechanisms, a process framework, a pallet and a solution box, wherein the lifting control mechanism is installed on a machine stand plate of the machine stand adjusting mechanism, the solution box is fixedly installed on the lifting control mechanism through the pallet, and a stirring and strickling piece is installed in the solution box; and four corners of the process framework are installed on the machine stand plate of the machine stand adjusting mechanism through the adjusting mechanisms, the process framework is arranged above the solution box, and iron bars are arranged on the process framework. The coating and polymerization device can complete three kinds of operation such as graphite and silver paste coating and polymerization of the chip solid capacitor core through replacing the solution box and solution integrally, the raw material contact parts do not need to be cleaned, the replacement working procedure is rapid, the operation is simple, and the efficiency is high; and the coating and polymerization device guarantees that the chip solid capacitor core has good process dimension and appearance consistency as well as high product reliability.
