Cleaning device and cleaning jig for large-size ceramic chip

The cleaning jig comprises a rotating frame and a plurality of fixing mechanisms which are circumferentially distributed on the rotating frame and used for installing and fixing the ceramic chips, and each fixing mechanism comprises a fixing plate and two fixing pieces which are arranged at the two ends of the fixing plate respectively and connected with the rotating frame. The fixed plate comprises a fixed plate body and a plurality of mounting grooves which are formed in the fixed plate body at intervals and are used for mounting ceramic chips; cleaning of the ceramic chip after electroplating belongs to a high-speed cleaning process, firstly, surface stains, tin marks and other residues after electroplating are removed through soft particles in a polishing solution, and then pure water is used for cleaning; the high-speed cleaning process does not allow the chip to have a free point and need rigid fixation, so that the surface quality and the product appearance of the chip can be improved under the conditi
