LCD module glass substrate automatic grinding machine

Abstract

The invention discloses a full-automatic grinding machine for liquid crystal module glass substrates, and the problem in the prior art that dirt cannot be cleaned cleanly and thoroughly during grinding of the glass substrates is solved. The full-automatic grinding machine is characterized in that a mechanism is fixed on a moving mechanism provided with an X axis, a Y axis, a Z axis and a theta axis; and the X axis, the Y axis, the Z axis and the theta axis cooperate with one another under the control of a PLC (Programmable Logic Controller), so that rotary grinding on all the surface of a glass substrate (1) can be realized. Each grinding head mechanism of the full-automatic grinding machine consists of an upper part and a lower part which are connected through a connection shaft (12), and an inverted-L-shaped right section upper clamping block (13) and an I-shaped left section upper clamping block of each upper part are mainly used for clamping the corresponding connection shaft (12); an elastic cushion block (3) is arranged on the bottom end surface of each grinding head insertion block (4); and a grinding sheet (2) is arranged on the lower bottom surface of each elastic cushion block (3). The full-automatic grinding machine is especially applicable to cleaning dirt with high adhesiveness on the glass substrates.

Description

technical field [0001] The invention relates to a rotary grinder, in particular to a full-automatic grinder used in the grinding process of removing dirt from a glass substrate of an LCD (Liquid Crystal Display) liquid crystal module before sticking a film. Background technique [0002] The electronic information industry is the most dynamic and rapidly developing industry today, and LCD manufacturing technology is a key technology in the information industry chain. During LCD manufacturing, glass substrates are ground to remove smudges. The prior art is accomplished by manual grinding or mechanical grinding belt grinding, and the grinding belt grinding is achieved by grinding the horizontally moving glass substrate through the reciprocating horizontal movement of a grinding belt to achieve decontamination. Manual grinding costs are high and the efficiency is low; the efficiency is improved by mechanically manipulating the grinding belt, but the glass substrate is subjected...
