Substrate cutting device for liquid crystal display module production

Abstract

The invention relates to the technical field of liquid crystal display module processing accessory devices, in particular to a substrate cutting device for liquid crystal display module production. The occurrence of the phenomenon that an operator is scratched by a cutter during work is avoided, the potential safety hazard is reduced, the practicability is improved, a fixing effect on a light guiding plate is improved, and the cutting accuracy is improved. The substrate cutting device for liquid crystal display module production comprises a cutting table, a support, two groups of electric cylinders, a support plate, a stamping air cylinder, an installation plate, telescopic rods, a piston rod, a cutter, a left fixing plate, a right fixing plate, a protection plate, four groups of guide pillars, four groups of guide sleeves, a central processing unit, a controller, pressing plates, springs and pressure sensors. Left strip-shaped holes and right strip-shaped holes in the vertical direction are formed in the left ends and the right ends of the four groups of guide sleeves; left limiting rods and right limiting rods are arranged on the left sides and the right sides of the top ends ofthe four groups of guide pillars; the four groups of left limiting rods are located in the four groups of left strip-shaped holes; a cutting hole is formed in the middle of the protection plate; and acutting slot is formed in the top end of the cutting table.
