Problems solved by technology

[0005] However, in the actual application of the traditional high-pressure spray device, we found that it brought us a lot of problems while bringing a good cleaning effect
Because it is a high-pressure spray, the high-pressure water flow often cannot achieve uniform pressure spray after spraying on the surface of the substrate
In this way, on the surface of the substrate that already has a film layer, due to the problem of uneven spray pressure, various defects will occur on the display substrate, resulting in the phenomenon of line shadow (Line Mura) when the display panel is finally prepared and formed.

Embodiment 1

[0031] This embodiment provides a spraying device, such as Figure 1-Figure 3 As shown, it includes a working unit 1, a supply unit 2 and a driving unit 3. The working unit 1 is used to rotate and spray cleaning agent to clean the substrate 7 to be cleaned; the supply unit 2 is used to provide cleaning agent for the working unit 1; the driving unit 3 is used to provide rotating power for the working unit 1.

[0032] By setting the working unit 1 capable of rotating and spraying, the spraying pressure of the cleaning agent is uniform when the spraying device is spraying, so that the surface of the substrate 7 to be cleaned is uniformly impacted by the spraying of the cleaning agent, thereby avoiding spraying. Defects caused by uneven pressure.

[0033] In this embodiment, the working unit 1 includes a spraying part 10 and a rotating shaft 13, the spraying part 10 is used to rotate under the drive of the rotating shaft 13, and spray cleaning agent to the substrate 7 to be clean...

Embodiment 2

[0046] This embodiment provides a cleaning device, including the spray device in Embodiment 1. The cleaning equipment is suitable for high-pressure cleaning of finished or semi-finished display substrates or other plate products during the production process of display products. The cleaning equipment can also be used in other fields that require high-pressure cleaning, such as high-pressure cleaning of cars. The cleaning equipment can make the high-pressure spraying of the cleaning agent more uniform, so as to achieve a better cleaning effect.

[0047] By adopting the shower device in Embodiment 1, the yield rate of the substrate cleaned by the cleaning equipment is improved.

Abstract

The invention discloses a spray device and cleaning equipment. The spray device comprises a working unit, a supply unit and a drive unit, and the working unit is used for rotationally spraying cleaning agent to clean a substrate to be cleaned; the supply unit is used for supplying cleaning agent for the working unit; the drive unit is used for supplying rotating power for the working unit. Through arranging the working unit capable of spraying rotationally, when the spray device sprays, the jet pressure of the cleaning agent is uniform, and accordingly the cleaning agent spray impact force on the surface of the substrate to be cleaned is uniform, and the badness caused by uneven spray pressure is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shower device and cleaning equipment. Background technique [0002] A liquid crystal display (LCD: Liquid Crystal Display) has become a mainstream product in flat panel displays due to its small size, low power consumption, and no radiation. The liquid crystal display panel is a key component in a liquid crystal display. [0003] In the preparation process of liquid crystal display panels, it usually involves the process of cleaning the display substrate with a certain film layer. For example, in the preparation process of low-temperature polysilicon (LTPS) liquid crystal display panels, each wet etching process is completed on the display substrate. After the steps, the display substrate will be cleaned by high-pressure spraying. [0004] The high-pressure spray device used in the high-pressure spray cleaning process of the display substrate is usually fixed in the spray ch...
