[0037] Please refer to Image 6 , the first embodiment of the present invention provides an acid dropping device, which is used to perform acid drop etching on the metal conductive layer on the color filter substrate, so that the alignment mark covered by the metal conductive layer appears. The acid dripping device includes a motor 101 , an acid liquid storage tank 102 , a pipeline 103 , an acid dripping head 104 , a fluid replacement alarm sensor 106 , an acid injection port 107 and a sponge 108 .

[0038] The acid liquid storage tank 102 is used for supplying acid liquid to the acid dripping head 104, and the upper end of the acid liquid storage tank 102 is provided with a motor 101, and the lower end of the acid liquid storage tank 102 is provided with a pipeline 103, and the acid liquid storage tank 102 and the acid dripping head 104 Connected by the pipeline 103 , the motor 101 squeezes out the acid liquid from the acid liquid storage tank 102 and sends it to the acid dri...

[0050] Please refer to Figure 10 , the acid drip device provided in the second embodiment of the present invention, including a motor 101 , an acid liquid storage tank 102 , an acid drip head 104 , a fluid replacement alarm sensor 106 , an acid injection port 107 and a sponge 108 . The main difference between this embodiment and the first embodiment above is that in this embodiment, the acid drip head 104 is directly installed with the acid liquid storage tank 102 to form a cylindrical structure, and the acid liquid storage tank 102 is located on the upper part of the cylindrical structure , The acid drip head 104 is located at the lower part of the cylindrical structure, thereby canceling the pipeline 103 connected between the acid liquid storage tank 102 and the acid drip head 104, the structure is simpler, and the use is easier. Wherein, the connection method between the acid drip head 104 and the acid liquid storage tank 102 can be threaded connection, buckle connection o...

Abstract

The invention discloses an acid dropping device. The acid dropping device is used for carrying out acid-dropping etching on a metal conducting layer, and alignment marks covered with the metal conducting layer are displayed; the acid dropping device comprises an acid dropping head, a sponge is embedded into one end of the acid dropping head, one end of the sponge is exposed out of the acid dropping head, and the exposed end of the sponge is used for being in contact with the metal conducting layer, and the metal conducting layer is etched through acid liquid in the sponge during contact. According to the acid dropping device, a needle head is changed into the sponge, the current acid dropping mode is changed into a 'seal-type' mode, the acid amount is controlled in the acid dropping process, the acid-dropping diffusion problem is effectively solved, and the good yield is increased; on the premise that a mask cannot be required to be used, etching holes are formed to enable the alignment marks to be displayed, and the making cost is greatly reduced. The invention also provides an acid dropping machine table and a making method of a touch display screen.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an acid dripping device, an acid dripping machine and a manufacturing method of a touch screen. Background technique [0002] When the liquid crystal panel industry manufactures touch screens with on-cell technology, after the liquid crystal panel (LCD) is assembled on the thin film transistor array substrate and the color film substrate, it is necessary to make a touch panel (Touch Panel, TP) on the color film substrate. ). In order to avoid abnormal touch function due to excessive overlap and offset between the touch panel and the liquid crystal panel, it is necessary to use alignment marks for alignment when manufacturing the first film of the touch panel. like figure 1 , is a schematic diagram of alignment marks in the liquid crystal panel in the prior art. At present, when making the first film of the touch panel, it is necessary to make alignment marks 11 in the liquid c...
