Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0022] A preferred embodiment of the present invention provides an aeration tube and an aeration pan. The aeration pan is used to provide air pressure for the etching liquid when the immersion spray etching machine etches the glass substrate of the liquid crystal display.

[0023] see figure 1 , the aeration tube 10 of the present invention is a hollow tube body, which includes a tube wall 11 , a cavity (not marked) surrounded by the tube wall 11 and open ends 12 located at both ends of the tube wall 11 . The pipe wall 11 is provided with several first air holes 13 arranged in a line along the axial direction. The plurality of linearly arranged first air holes 13 are at least arranged in one row. At least one second vent hole 14 is provided on the tube wall 11 near each ope...

Abstract

The invention provides an aeration pipe. The aeration pipe is a hollow pipe, which includes a pipe wall, a cavity surrounded by the pipe wall, and two open ends located at two ends of the pipe wall. A plurality of first vents are arranged in a line along an axial direction of the pipe wall. A second vent is arranged near each open end and is located between the open end and the outermost first vent of the plurality of first vents. A line where the centers of the second vents are and a line where the central lines of the first vents are are in dislocation arrangement. The diameter of each first vent is smaller than that of each second vent. The invention further provides an aeration disc and an immersion etching machine.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel manufacturing, in particular to an aeration tube, an aeration disc and an immersion etching machine. Background technique [0002] Liquid crystal display is the mainstream flat panel display device technology in the market today. The general structure of the liquid crystal glass substrate of the existing liquid crystal display includes: a TFT substrate and a CF substrate laminated up and down, and liquid crystal molecules poured between the TFT substrate and the CF substrate . Before the standard liquid crystal glass substrate is formed, it is necessary to thin, cut and separate the glass substrate mounted on the plate. Wherein, thinning refers to reducing the glass thickness of the two opposite outer surfaces of the glass substrate to meet the required thickness of the liquid crystal glass substrate as specified in the design. In the prior art, commonly used thinning equipment incl...
