Abstract

The utility model discloses a grinding polishing system of a light-emitting diode (LED) substrate. The grinding polishing system of the LED substrate comprises a polishing grinder and a polishing agent recycling groove, wherein the polishing agent recycling groove is connected with a coarse strainer, a metering pump and a fine filter through pipelines in sequence, a control valve is arranged between the coarse strainer and the metering pump, a discharge outlet of the fine filter is connected with a feed inlet pipeline of the polishing grinder, and a switching valve is arranged between the fine filter and the polishing grinder. The fine filter comprises a shell body and a micropore folded filter element, wherein the micropore folded filter element is a teflon film filter element, and a filter pore diameter is 0.5-1 micrometer. Due to the fact that polishing agents which are used are filtered through a plurality of layers and especially through the fine filter with the teflon film filter element, impurities of the used polishing agents are removed to the maximum extent, stability of the polishing agents is effectively ensured, quality of the polishing agents is ensured when the polishing agents are used again, and recycling and stability of the polishing agents are achieved. The grinding polishing system of the LED substrate is simple in structure and convenient to operate.
