Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal screen cleaning, in particular to a grinding belt used for cleaning liquid crystal screens. Background Art

[0002] With the continuous development and widespread application of LCD technology, the cleaning of LCD screens during the production process is particularly important, as it directly affects the quality and display effect of LCD screens. Before the LCD screen is assembled, the surface of the LCD screen must be cleaned carefully and efficiently to remove various tiny particles, organic stains and other impurities attached during the production process to prevent these pollutants from affecting the internal structure and display performance of the LCD screen.

[0003] However, existing LCD screen cleaning methods and technologies have obvious shortcomings. Currently, the common LCD screen cleaning grinding belts on the market mostly use hard abrasives such as brown corundum as grinding media. This type of abrasive has a high hardness and can easily cause accidental scratches on the surface of the LCD screen during the cleaning process. Not only can it fail to achieve the ideal cleaning effect, but it will also damage the surface quality and service life of the LCD screen. In addition, the structural design of the existing grinding belt is not reasonable enough, and the stains generated during the grinding process are difficult to effectively discharge, which can easily cause secondary pollution and reduce the cleaning efficiency. At present, no effective solution has been proposed for the problems in the related technology. Therefore, it is necessary to propose a grinding belt for LCD screen cleaning to solve the above-mentioned problems. Utility Model Content

[0004] In view of the problems in the related art, the utility model proposes a grinding belt for cleaning a liquid crystal screen to overcome the above technical problems existing in the existing related art.

[0005] To this end, the specific technical solutions adopted by the utility model are as follows:

[0006] A grinding belt for cleaning a liquid crystal screen comprises a grinding base, a cleaning groove is formed on one side surface of the grinding base, grinding abrasives are bonded and mounted on the surface of the grinding base and the inner wall of the cleaning groove, an extrusion groove is formed inside the grinding base, an absorption hole is connected through the cleaning groove and the extrusion groove, a closing cover is installed at one end of the absorption hole, one side of the closing cover is fixedly connected to the inner wall of the extrusion groove, an exhaust pipe is fixedly installed at one end of the extrusion groove, a one-way exhaust valve is fixedly installed at one end of the exhaust pipe passing through the grinding base, a sealing pad is installed on the bottom surface of the grinding base, a sealing block is fixedly connected to the surface of the sealing pad, an installation groove is formed on the bottom surface of the grinding base, and the size of the sealing block matches the installation groove.

[0007] Furthermore, in order to protect the LCD screen during grinding and cleaning, the grinding abrasive is a three-dimensional tower structure made of aluminum oxide. By adopting soft abrasives made of aluminum oxide and a flat-top tower structure, the damage to the LCD screen during grinding and cleaning can be reduced, and the surface of the LCD screen can be prevented from being scratched by hard grinding abrasives.

[0008] Furthermore, in order to enable the grinding base to be repeatedly squeezed and reset, the grinding base is made of elastic rubber. The grinding base made of elastic rubber can allow the extrusion groove to shrink freely before and after being squeezed.

[0009] Furthermore, in order to achieve cleaning of different positions on the surface of the grinding base, the cleaning grooves are evenly arranged on the surface of the grinding base, and the grinding abrasives are evenly bonded to the surfaces of the grinding base and the cleaning grooves. Through the cleaning grooves and grinding abrasives evenly arranged on the surface of the grinding base, the surface of the LCD screen is continuously ground and cleaned, and impurities are collected.

[0010] Furthermore, in order to realize that the absorption hole on one side of the extrusion groove only realizes the absorption function, the material of the closing cover is elastic rubber, the connection between the extrusion groove and one side of the closing cover is elastically connected, the diameter of the closing cover is larger than the absorption hole, through the elastic connection between one side of the closing cover and the extrusion groove, when the extrusion groove is squeezed and needs to be exhausted, since the diameter of the closing cover is larger than the absorption hole, the gas cannot be discharged from the absorption hole. When the extrusion groove needs to inhale, the gas at one end of the absorption hole pushes the elastically connected closing cover to move into the extrusion groove, and absorbs gas and impurities into the extrusion groove through the absorption hole.

[0011] Furthermore, in order to prevent the sealing gasket from falling off after installation, a Velcro fur surface is fixedly installed on the side surface of the grinding base, and a Velcro hook surface is sewn and connected to the side surface of the sealing gasket. The Velcro fur surface and the Velcro hook surface are bonded to each other, making the sealing gasket installed at the bottom of the grinding base more stable.

[0012] The beneficial effects of the utility model are:

[0013] 1. During grinding and cleaning, the grinding base made of elastic rubber is pressed to compress the extrusion groove in the grinding base, and the gas in the extrusion groove is discharged from the exhaust pipe. The surface of the LCD screen is cleaned by the grinding abrasive on the surface of the grinding base and the cleaning groove. When the extrusion groove is no longer pressed after cleaning, the extrusion groove reabsorbs the gas from the absorption hole through its own elastic force. While absorbing the gas, the dust and impurities ground and cleaned on the surface of the LCD screen are absorbed into the extrusion groove for collection, so as to prevent the LCD screen from causing secondary pollution after grinding and cleaning.

[0014] 2. The soft abrasive made of silicon oxide can reduce the scratch rate of the LCD screen during grinding and cleaning; the use of a three-dimensional tower-shaped abrasive can help form more gaps during the grinding process, making it easier for the cleaning tank to accommodate and discharge stains and debris generated during the grinding process, further preventing impurities from causing secondary pollution after grinding, and avoiding damage to the LCD screen surface caused by the tip of the traditional abrasive.
