Packaging method, packaging apparatus, and terminal
Embodiments of the present invention relate to the communications field, and provide a packaging method, a packaging apparatus, and a terminal, so as to improve evenness of an adhesive layer and reduce an adhesive overflow probability, thereby improving packaging efficiency and a defect-free rate of terminals. The method includes: forming an adhesive layer on a packaging surface of a packaging module, where a shape and a size of the adhesive layer adapt to the packaging surface; and fastening, into a terminal housing, the packaging module on which the adhesive layer is formed, so that the adhesive layer is filled between the packaging surface and a side wall of the housing.
1. A packaging method, comprising:
forming an adhesive layer on a packaging surface of a packaging module, wherein a shape and a size of the adhesive layer adapt to the packaging surface; and
fastening, into a terminal housing, the packaging module on which the adhesive layer is formed, so that the adhesive layer is filled between the packaging surface and a side wall of the housing.
2. The method according to claim 1 , wherein the forming an adhesive layer on a packaging surface of a packaging module comprises:
coating a substrate membrane with sealant;
pressing the sealant-coated side of the substrate membrane onto the packaging surface, so that the sealant is attached onto the packaging surface; and
removing the substrate membrane to form the adhesive layer.
3. The method according to claim 2 , wherein the pressing the sealant-coated side of the substrate membrane onto the packaging surface comprises:
adjusting a relative position between the substrate membrane and the packaging surface, so that a vertical projection of the sealant on the packaging surface coincides with the packaging surface; and
moving the substrate membrane onto the packaging surface and applying pressure on the substrate membrane.
4. The method of claim 3 , after the removing the substrate membrane, further comprising:
polishing the adhesive layer, so that a shape and a size of a surface, in contact with the packaging surface, of the adhesive layer are the same as the shape and the size of the packaging surface.
5. The method of claim 3 , wherein the fastening, into a terminal housing, the packaging module on which the adhesive layer is formed comprises:
mounting, into the housing, the packaging module on which the adhesive layer is formed;
heating the adhesive layer, so that the adhesive layer becomes sticky again; and
fastening the packaging module into the housing by using the adhesive layer.
6. The method according to claim 2 , wherein the removing the substrate membrane comprises:
tearing off the substrate membrane before the sealant is fully cured.
7. The method of claim 6 , after the removing the substrate membrane, further comprising:
polishing the adhesive layer, so that a shape and a size of a surface, in contact with the packaging surface, of the adhesive layer are the same as the shape and the size of the packaging surface.
8. The method of claim 6 , wherein the fastening, into a terminal housing, the packaging module on which the adhesive layer is formed comprises:
mounting, into the housing, the packaging module on which the adhesive layer is formed;
heating the adhesive layer, so that the adhesive layer becomes sticky again; and
fastening the packaging module into the housing by using the adhesive layer.
9. The method of claim 2 , after the removing the substrate membrane, further comprising:
polishing the adhesive layer, so that a shape and a size of a surface, in contact with the packaging surface, of the adhesive layer are the same as the shape and the size of the packaging surface.
10. The method of claim 9 , wherein the fastening, into a terminal housing, the packaging module on which the adhesive layer is formed comprises:
mounting, into the housing, the packaging module on which the adhesive layer is formed;
heating the adhesive layer, so that the adhesive layer becomes sticky again; and
fastening the packaging module into the housing by using the adhesive layer.
11. The method of claim 2 , wherein the fastening, into a terminal housing, the packaging module on which the adhesive layer is formed comprises:
mounting, into the housing, the packaging module on which the adhesive layer is formed;
heating the adhesive layer, so that the adhesive layer becomes sticky again; and
fastening the packaging module into the housing by using the adhesive layer.
12. The method of claim 1 , wherein the fastening, into a terminal housing, the packaging module on which the adhesive layer is formed comprises:
attaching a double-sided tape to a bottom surface of the packaging module on which the adhesive layer is formed; and
fastening the packaging module into the housing by using the double-sided tape.
13. The method of claim 1 , wherein the fastening, into a terminal housing, the packaging module on which the adhesive layer is formed comprises:
mounting, into the housing, the packaging module on which the adhesive layer is formed;
heating the adhesive layer, so that the adhesive layer becomes sticky again; and
fastening the packaging module into the housing by using the adhesive layer.
14. The method of claim 1 , wherein the packaging module comprises a cover glass CG and a display module that are disposed opposite, and the CG and a surface, perpendicular to a display surface, of the display module form the packaging surface.
15. A terminal, comprising a housing and a packaging module disposed in the housing, wherein the housing and the packaging module are packaged together by using the packaging method of claim 1 .
