Embodiment 1

[0030] The cutting process of the glass panel 1 surface protection film 2 of the present embodiment is as follows:

[0031] After cleaning and drying the surface of the corresponding glass panel 1 that needs to be filmed, stick the protective film 2 on the surface of one side of the glass panel 1 manually or with a CCD film laminating machine for protection, and the size of the protective film 2 exceeds the size of the glass panel 1. Size, that is to say, the size of the protective film 2 is slightly larger than the size of the glass panel 1. Here, the protective film 2 is an explosion-proof film; defoaming is carried out after the film is pasted, so that the protective film 2 is completely attached to the surface of the glass panel 1, and the quality is checked. Happening;

[0032]Use carbon dioxide to cool the area to be cut on the protective film 2 to cool the protective film 2, and use a laser radium engraving machine to carry out radium engraving and cutting processing to...

Embodiment 2

[0035] The cutting process of the glass panel 1 surface protection film 2 of the present embodiment is as follows:

[0036] After cleaning and drying the surface of the glass panel 1 that needs to be filmed, use a special CCD film laminating machine to attach the protective film 2 to one side of the glass panel 1 for protection, and the size of the protective film 2 exceeds the size of the glass panel 1 , that is to say, the size of the protective film 2 is slightly larger than the size of the glass panel 1, and the protective film 2 here is an explosion-proof film; defoaming is carried out after the film is pasted, so that the protective film 2 is completely attached to the surface of the glass panel 1, and the quality is checked ;

[0037] Use carbon dioxide to blow the surface of the protective film 2 to cool the area to be cut on the protective film 2. After cooling the protective film 2, use a laser laser engraving machine to carry out radium engraving and cutting. The pr...

Embodiment 3

[0040] The cutting process of the glass panel 1 surface protection film 2 of the present embodiment is as follows:

[0041] After cleaning and drying the surface of the glass panel 1 that needs to be filmed, use a special CCD film laminating machine to attach the protective film 2 to one side of the glass panel 1 for protection, and the size of the protective film 2 exceeds the size of the glass panel 1 , that is to say, the size of the protective film 2 is slightly larger than the size of the glass panel 1. Here, the protective film 2 adopts ARAF optical film; defoaming is carried out after the film is pasted, so that the protective film 2 is completely attached to the surface of the glass panel 1, and the quality is checked Happening;

[0042] The cooling of the protective film 2 by cooling treatment is carried out synchronously with the laser engraving and cutting of the excess part of the protective film by a laser engraving machine, and the cutting area in front of the la...

Abstract

The invention relates to a cutting method for a protective film covering the surface of a glass face plate, and belongs to the technical field of glass surface film cutting treatment. The cutting method aims to solve the problem of low film attaching precision in the prior art. According to the cutting method for the protective film covering the surface of the glass face plate, the method comprises the following steps that the protective film is attached to the surface of the glass face plate for protection, and the size of the protective film is greater than that of the glass face plate; anda laser engraving cutting procedure is entered, the protective film is cooled by adopting cooling treatment, and then the redundant part, exceeding the size of the glass face plate, of the protectivefilm is cut off along the peripheral edge of the glass face plate by adopting laser engraving cutting treatment to obtain the glass face plate to which the protective film corresponding to the glass face plate in size is correspondingly attached. According to the cutting method for the protective film covering the surface of the glass face plate, the cutting precision is high, the film attaching consistency is good, and the sizes of the protective film and the glass face plate are consistent, so that the 1 to 1 attaching requirement is met, and it can also be guaranteed that damage to the glass face plate is avoided.

Description

technical field [0001] The invention relates to a cutting method for covering a protective film on the surface of a glass panel, and belongs to the technical field of glass surface film cutting processing. Background technique [0002] At present, electronic products are updated rapidly, and there is a huge demand for electronic products such as mobile phones. During the normal use of mobile phones, the main screen of the mobile phone is used in a huge amount, and the wear and tear is the most serious. The main screen of the mobile phone is made of plastic and glass. The market The upper glass cover occupies the largest proportion, so the glass cover is very strict in the production process. The glass cover is usually protected with a film. After the film is applied, the excess part of the edge of the protective film will be cut off to make it correspond Corresponds to the size of the glass cover. The existing cutting process is basically to die-cut the protective film by u...
