Baseplate cutting system

The invention relates to the technical field of display, and particularly relates to a baseplate cutting system. The baseplate cutting system comprises a cutting groove, an objective table, a cutting knife assembly, a water injection pump and an effluent pump, wherein the water injection pump is used for injecting water into the cutting groove; the effluent pump is used for pumping water from the cutting groove; a flowable water environment is formed in the cutting groove under the action of the water injection pump and the effluent pump; the objective table is a movable base table and is used for transferring a baseplate to be cut to the water environment in the cutting groove; and the cutting knife assembly is used for cutting the baseplate. The baseplate cutting system has the beneficial effects that glass cullet generated due to cutting is taken away by using the flowable water environment, so that the glass cullet generated due to cutting cannot enter ambient environments; and meanwhile, harmful conditions such as surface scratching, electrode edge scratching and circuit scratching caused by the glass cullet remaining on the surfaces of products can also be avoided.
