Embodiment 1

[0064] Such as Figure 2-Figure 4 As shown, this embodiment is a tooling tool for 3D glass film sticking, including a base plate 20 and a film absorbing plate 30 that is sealed with the base plate 20 and is used to absorb the decorative film 40 . The groove 21, the bottom plate 20 and the film suction plate 30 are all provided with ventilation holes.

[0065] The tooling tool for 3D glass film sticking provided by the present invention includes a base plate 20 and a film absorbing plate 30 for absorbing a decorative film 40. The base plate 20 is provided with a groove 21 for placing the 3D glass 10. The base plate 20 and the film absorbing plate 30 can be covered. After closing and covering, a closed space for accommodating the 3D glass 10 and the decorative film 40 will be formed in the middle. On the bottom plate 20 and the suction film plate 30, air holes are all arranged, and the evacuation process to the closed space can be realized through the air holes on the bottom pl...

Embodiment 2

[0072] This embodiment provides a method for attaching a film to 3D glass. The bonding equipment used in the method for attaching the film includes the tooling tool for attaching a film to 3D glass in Example 1, which specifically includes the following steps:

[0073] Step a) Loading: Lay the 3D glass flat in the groove of the bottom plate, and use the film-absorbing plate to absorb the decorative film; when absorbing the decorative film, use the CCD alignment method to grab the decorative film, and according to the decorative film and the film-absorbing plate Positioning holes on the suction plate to place it at a specific position;

[0074] Among them, the heat-resistant temperature of the decorative film is 120°C;

[0075] Step b) heating: using infrared heating to heat the decorative film to 110°C to soften the decorative film;

[0076] Step c) Vacuuming: After the film-absorbing plate is combined with the base plate, the 3D glass and the decorative film are located in t...

Embodiment 3

[0081] This embodiment provides a method for attaching a film to 3D glass. The bonding equipment used in the method for attaching the film includes the tooling tool for attaching a film to 3D glass in Example 1, which specifically includes the following steps:

[0082] Step a) Loading: Lay the 3D glass flat in the groove of the bottom plate, use the film absorbing plate to absorb the decorative film; when absorbing the decorative film, use the CCD alignment method to grab the decorative film, and according to the positioning hole on the decorative film Place it on the specific position of the suction film plate;

[0083] Among them, the heat-resistant temperature of the decorative film is 130°C;

[0084] Step b) heating: using infrared heating to heat the decorative film to 115°C to soften the decorative film;

[0085] Step c) Vacuuming: Then position according to the positioning holes on the decorative film, the bottom plate and the suction film plate, cover the suction film...

Abstract

The invention provides a film pasting method for 3D glass, a tool used for 3D glass film pasting and a film pasting device, and relates to the technical field of film pasting. The film pasting methodfor the 3D glass includes the steps that the surface of the 3D glass is covered with a heated decoration film, and then the 3D glass is placed in a closed space to be subjected to vacuumizing treatment; and then, gas is injected in the closed space to conduct pressurization on the decoration film so that the decoration film can pressed and attached to the surface of the 3D glass. By means of the film pasting method, the technical problems that in an existing film pasting process of 3D glass, particularly 3D glass with the edge curving radian larger than 60 degrees, it is difficult to achieve attachment on the edges of the 3D glass, and therefore the attachment yield is low and mass production cannot be achieved can be solved, generation of bubbles and a defective product with folds at thefour corners is reduced, and the film pasting yield of the 3D glass is increased.

Description

technical field [0001] The invention relates to the technical field of film sticking, in particular to a film sticking method for 3D glass, tooling and film sticking equipment for 3D glass film sticking. Background technique [0002] With the explosive development of mobile phone covers, 3D mobile phones have been developing rapidly. At present, in the glass back cover of 3D mobile phones, a large number of mobile phone manufacturers use a structure that combines decorative films and glass substrates. For the bonding of the decorative film to the 3D glass, the existing process is to first cover the decorative film on the surface of the 3D glass, and then use a roller and a silicone mold to squeeze the decorative film to complete the bonding of the decorative film to the 3D glass. [0003] At present, in order to meet the differentiated design of mobile phones, the edge curvature of the 3D glass casing is getting steeper and steeper. When the edge curvature of the 3D glass s...
