Problems solved by technology

[0003] (1) Some parts of the shell are decorated with metal parts, which are combined and fixed by glue, buckles or plastic hot-melt columns. However, the defect of this method is that the metal texture of the appearance is incomplete due to avoiding the clearance area of ​​the antenna. , affecting the appearance; on the other hand, there is a gap between metal and plastic, which is prone to poor appearance;
[0004] (2) The shell part is formed by stamping, and part of it is processed by CNC. However, the defect is that the bending angle of the general stamping parts is not accurate and the rebound force is large, which leads to the four side fillet positions on the mobile phone. The matching gap between the plastic and metal decorative parts is uneven, and the delamination phenomenon is easy to occur at the disconnection of the plastic and metal decorative parts after dispensing and holding pressure; on the other hand, after the plastic and metal decorative parts are assembled by dispensing, the bend Tends to snap back, resulting in large gaps and an unsightly appearance

Embodiment 1

[0039] The present invention is used for the assembly structure of the metal decoration of mobile phone front case, as Figure 1 to Figure 4 As shown, it includes an aluminum alloy frame 1 and a plastic 2 fixed on the inner wall of the aluminum alloy frame 1. The aluminum alloy frame 1 is made of an aluminum alloy plate through CNC processing, and the four bending corners of the aluminum alloy frame 1 are all set The corners are bent in a circular arc shape, and the inner wall of the aluminum alloy frame 1 is bonded and fixed to the plastic 2 . The aluminum alloy frame 1 processed by CNC has a good shape, and the arcs of the four bending corners of the aluminum alloy frame 1 will not spring back, so there is no gap between the metal decorative parts and the plastic 2. The gap can be better bonded and fixed with the plastic 2.

[0040] The aluminum alloy frame 1 is divided into multiple sections, and the inner wall of the aluminum alloy frame 1 located at the split point 3 is ...

Embodiment 2

[0044] The processing and assembling method for the assembly structure of the metal decoration of the mobile phone front shell of the present invention, such as figure 1 To such as image 3 shown, including the following steps:

[0045] (1) Clamp fixation:

[0046] Fix the aluminum alloy plate through the clamp;

[0047] (2) CNC processing:

[0048] According to the drawing, the aluminum alloy frame 1 that is consistent with the internal structure of the front shell of the mobile phone and has four arc-shaped bending corners is processed by CNC step by step;

[0049] (3) Split into segments:

[0050] The aluminum alloy frame 1 is divided into segments, and the inner wall of each division 3 of the aluminum alloy frame 1 and the surrounding of the inner wall of the aluminum alloy frame 1 are formed with screw columns 11 by CNC machining;

[0051] (4) Dispensing and bonding:

[0052] The aluminum alloy frame 1 is located at the split point 3 and the screw column 11 at the ...

Abstract

The invention relates to the technical field of a mobile phone and specifically to an assembly structure for a metal decorating part of a mobile phone front shell and a processing and assembling method of the assembly structure. The method comprises the steps as follows: using CNC machining to form an aluminium alloy plate, segmenting aluminium alloy frames in a CNC machining process as segments, using the CNC machining to form bolt columns at the inner side wall located at each segmenting place of the aluminium alloy frame, wherein the bolt columns correspond to screw holes on a plastic one by one, then dispensing glue at a junction surface of the aluminium alloy frame and the plastic so as to stick and fix the aluminium alloy frame and the plastic, using the bolts to lock and fix the screw holes of the bolt columns and the plastic after dispensing glue. Compared with prior art, the assembly structure and the method of the invention could effectively solve the problem that the glue dispensing place of the plastic and the metal decorating part is easy to generate delaminating and the gap between the plastic and the metal decorating part is oversize, and a bending part is hard to rebound, thereby greatly improving metal appearance effect of the mobile phone.

Description

technical field [0001] The invention relates to the technical field of mobile phones, in particular to an assembly structure and a processing and assembling method of a metal decorative part used for a front case of a mobile phone. Background technique [0002] As the requirements for the finer appearance of mobile phones are getting higher and higher, the use of metal casings in mobile phones is also increasing. There are two main ways to apply metal casings on mobile phones: [0003] (1) Some parts of the shell are decorated with metal parts, which are combined and fixed by glue, buckles or plastic hot-melt columns. However, the defect of this method is that the metal texture of the appearance is incomplete due to avoiding the clearance area of ​​the antenna. , affecting the appearance; on the other hand, there is a gap between metal and plastic, which is prone to poor appearance; [0004] (2) The shell part is formed by stamping, and part of it is processed by CNC.
