Rotary spray head and wet etching machine

Abstract

The invention provides a rotary spray head. The rotary spray head comprises a spray head body installed on a rotary joint. The spray head body comprises at least N spray pipes which are distributed along a radial direction of the rotary joint, wherein N is a positive integer larger or equal to 3. One ends opposite to the spray pipes are connected and communicate with each other. The spray joint is connected with the joint of the spray pipes. Spray nozzles with adjustable spacing distances are arranged on the lower end surface of the spray pipes and communicate with a pipe cavity 13 of the spray pipes. The invention further provides a wet etching machine. The wet etching machine comprises the above rotary spray head. Compared with the prior art, the rotary spray head and the wet etching machine have following beneficial effects: through the spray head body composed of more than three spray pipes equipped with the adjustable spacing-distance spray nozzles, problems such as uneven etching or uneven colors (Mura) caused by uneven spraying that may easily arise from etching are solved, thereby reducing the number of the spray pipes and reducing cost of material adoption.

Description

technical field [0001] The invention relates to a liquid crystal panel technology, in particular to a rotary shower head and a wet etching machine for wet etching. Background technique [0002] At present, in the preparation of liquid crystal panels, wet etching is generally carried out by swinging spraying perpendicular to the forward direction of the glass. This method is prone to problems such as uneven etching or uneven color; and the spraying required by the traditional swinging spraying method The number of pipes is large, one machine has three etching tanks, each etching tank has 54 sprinkler heads, and the total number of sprinkler heads in one machine is 162, resulting in higher material costs; in order to ensure the normal spraying status of the sprinkler heads If it is not blocked, more manpower is required for maintenance and inspection. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a ...
