Embodiment 1

[0020] refer to figure 1 , the crack filling method provided in the first embodiment, comprising the following steps:

[0021] In step S101, inject filling fluid into the fracture;

[0022] In step S102, placing a film on the crack, so that the filling liquid can penetrate into the crack through tension;

[0023] In step S103, applying a pressing force to the crack to change the structure of the crack so that the filling liquid can fully penetrate into the crack;

[0024] In step S104, ultraviolet curing is performed on the filling liquid penetrating into the crack.

[0025] In the embodiment of the present invention, firstly, the filling liquid is gradually poured on the crack through the container containing the filling liquid, and the container is gradually moved, so that the poured filling liquid can be injected and spread to cover the entire crack. Then, stick a film on the crack. The film can be a transparent plastic film. By moving the position of the film, the filli...

Embodiment 2

[0033] In the crack filling method provided in the second embodiment, when applying a pressing force to the crack, a pressing force is applied to the front and / or back of the crack. That is to say, when applying pressing force to the crack, applying pressing force to the front of the crack, under the condition that the filling fluid is filled with the crack, no pressing force can be applied to the back of the crack; or, applying pressing force to the back of the crack, In the case where the filling fluid has already filled the crack, no pressing force may be applied to the front of the crack; alternatively, pressing force may be applied to both the front and back sides of the crack.

[0034] For example, for a windshield, the front side is facing the external environment of the vehicle body, and the rear side is facing the internal environment of the vehicle body. When a hard object hits the windshield from the outside of the vehicle body, cracks will be formed on the windshie...

Embodiment 3

[0037] In the crack filling method provided in Embodiment 3 of the present invention, in order to allow the filling liquid to penetrate into the crack more fully, after injecting the filling liquid into the crack, the vacuum chuck is adsorbed on the crack, and the vacuum chuck is pulled and pressed several times.

[0038] When the vacuum chuck is adsorbed on the crack, a cavity is formed inside the vacuum chuck. The air pressure in the cavity is stable if no operation is performed on the vacuum chuck.

[0039] When the vacuum chuck is pulled, the structural shape of the vacuum chuck changes. Compared with the original structural shape, the upper part of the vacuum chuck after pulling is higher, and the lower part is narrower. At this time, the air moves to the upper part of the vacuum chuck, that is, to move above the cavity, causing the air pressure in the cavity to decrease near the crack, resulting in cracks A pressure difference is created between the top and the inside. ...

Abstract

The invention is suitable for the field of crack filling, and particularly relates to a crack filling method which comprises the following steps: filling liquid is injected into a crack; a film is placed on the crack, so that the filling liquid permeates into the crack under the action of tension; pressing force is applied to the crack, and the crack structure is changed, so that the filling liquid fully permeates into the crack; and ultraviolet curing is performed on the filling liquid permeating into the crack. For the position where the filling liquid is not prone to permeating, pressing force is applied to enable the crack to crack, the filling liquid can permeate along the crack which cracks again, in the permeating process of the filling liquid, the pressing force is applied to enable the crack to crack again, the filling liquid can permeate into all the gaps in the crack, the situation that no filling liquid exists in local gaps can be avoided, the finally-filled gaps are more compact, and the excellent filling effect is achieved.

Description

technical field [0001] The invention is applicable to the field of crack filling, and in particular relates to a crack filling method. Background technique [0002] Products made of glass, ceramics and other materials are often impacted by external or internal forces during use, resulting in large or small cracks. For example, during the running of a car, if a stone or other hard object suddenly flies and hits the windshield, it will easily leave cracks extending from the center of the impact to the surroundings, seriously affecting the appearance of the windshield. If the cracks are not repaired in time, it is easy to cause the cracks to expand and grow larger in the process of continuing to drive, and then cause damage to the entire windshield, bringing greater safety hazards to users. [0003] In the existing crack filling process, filling fluid is often only added to the crack, and after the filling fluid is filled, other filling tools are used to perform corresponding ...
