An electroplating film stripping device for glass surface and an electroplating film stripping method for glass surface

Abstract

A glass surface electroplating film stripping device, comprising a frame, on which a material transmission device and a plasma treatment device are arranged. A space is provided on the material transmission device, and the nozzle of the plasma treatment device is directly opposite to the space. The plasma treatment device is located above the space and sprays plasma from top to bottom. Compared with the prior art, the advantages of the present invention are as follows: 1. Components such as pressure rollers are not provided, so that the AF surface of the glass will not be contaminated by contact; 2. The plasma sprayed by the plasma treatment device is sprayed on the surface to be processed of the glass sheet to be processed, generating a fixing force similar to that applied by the pressure roller to the glass, thereby removing the pressure roller and also avoiding the pollution caused by the pressure roller to the glass surface.

Description

Technical Field

[0001] The present application relates to an electroplating film stripping device for the glass surface, and particularly to an electroplating film stripping device applicable to the glass of a finger touch screen and a stripping method thereof. Background Art

[0002] For the currently used touch screen glass, especially mobile phone glass, the surface of the glass needs to be coated by spraying to improve the anti-fingerprint performance of the touch screen. However, this spraying will form a coating layer surface on one side of the glass and electroplating film residues on the other side, which is commonly known as "pollution". To remove this "pollution", various technical solutions have been proposed, and a relatively representative one is the patent of CN206916219U.

[0003] The deficiencies of the current technology are as follows: 1. The plasma gun is below the conveying track, and the glass to be processed is on the conveying track. The surface of the glass with "pollution" faces the plasma gun, so that the plasma gun cannot spray onto the coating layer surface of the glass to avoid plasma damage to the coating layer surface. However, this technical solution will inevitably allow a small amount of plasma to bypass to the coating layer surface, thereby causing damage to the coating layer surface. In addition, because the plasma ejected by the plasma gun has a certain force, when blowing the glass from bottom to top, it will blow the glass to be processed. In order to fix the glass, the prior art needs to set up a pressure roller to press the coating layer surface of the glass to be processed. Since the pressure roller may carry pollutants, this will pollute the coating layer surface of the glass to a certain extent. Setting up the pressure roller itself increases the processing procedures and the components of the machine. Summary of the Invention

[0004] The object of the present invention is to overcome the above deficiencies of the prior art and is achieved by the following technical solutions:

[0005] An electroplating film stripping device for the glass surface includes a frame, on which a material conveying device and a plasma processing device are arranged. A space is provided on the material conveying device, and the nozzle of the plasma processing device faces the space. The plasma processing device is located above the space and ejects plasma from top to bottom.

[0006] Compared with the prior art, the advantages of the present invention are as follows: 1. Components such as pressure rollers are not provided, so that the AF surface of the glass will not be contaminated by contact; 2. The plasma ejected by the plasma processing device is sprayed on the surface to be processed of the glass sheet to be processed, generating a fixing force similar to that applied by the pressure roller to the glass, thereby removing the pressure roller and avoiding the pollution caused by the pressure roller to the glass surface; 3. The gravity of the glass to be processed itself can also play a certain role in preventing the glass from moving during processing. 4. Since the plasma is blown from top to bottom, and the coating layer surface of the glass is below, the plasma ejected by the plasma gun directly falls down due to gravity, thus avoiding the plasma directly falling on the coating layer surface of the glass and further damaging the coating layer surface of the glass.

A material transmission device (2) and a plasma processing device (3) are arranged on the frame. A space (4) is arranged on the material transmission device (2). The nozzle (3.1) of the plasma processing device (3) is directly opposite to the space (4). The plasma processing device (3) is located above the space (4) and sprays plasma from top to bottom. The above electroplating film stripping device does not include components that contact the transported material from top to bottom. The plasma processing device (3) is a plasma gun and the nozzle (3.1) of the plasma gun can move towards the space (4). The plasma ejected by the plasma gun is cylindrical and can be directly shot at the surface of the glass (5). The width d of the space (4) is greater than the diameter r of the plasma ejected by the plasma gun. The glass (5) is a finger touch screen glass.

[0015] The nozzle (3.1) of the plasma gun can move towards the space (4), so that the ejected plasma passes through the space (4) and is sprayed onto the surface of the glass (5).

The glass (5) includes a coated film layer surface (5.1) and a surface to be plasma processed (5.2). The surface to be plasma processed (5.2) is above the material transmission device (2), so that when the surface to be plasma processed (5.2) passes through the space (4), the plasma ejected by the plasma processing device (3) faces the surface to be plasma processed (5.2). The glass (5) is placed on the material transmission device (2) and the coated film layer surface (5.1) is attached to the material transmission device (2)
