Electronic product shell and preparation method
Technical Field
The invention relates to the field of electronic product shells, in particular to an electronic product shell and a preparation method thereof.
Background
The mobile phone is used as an intelligent device frequently used at present, the shell of the mobile phone is particularly important to be arranged, the mobile phone is required to have strength and wear resistance, and most consumers have extremely high requirements on the attractiveness of the mobile phone shell. The producer can increase a layer of pad pasting on the electronic product shell sometimes for the cell-phone has more variety, perhaps the consumer also can paste a rete on the electronic product shell often, however, because electronic product shell itself is planar, after pasting a rete, electronic product shell on the one hand can increase in thickness, on the other hand also can appear outstanding place in its border position, influences the outward appearance.
Disclosure of Invention
The invention provides an electronic product shell, which solves the problems that the electronic product shell is durable and not attractive after being additionally provided with a film.
In order to solve the technical problems, the technical scheme of the invention is as follows: the electronic product shell comprises a body, wherein the edge of the body is downwards bent in an arc shape of 1-60 degrees, a surrounding bone is arranged at the edge of the body, the surrounding bone and the body are integrally formed, a film is arranged above the body and is arranged in the surrounding bone, and the film is in seamless connection with the surrounding bone.
Preferably, the body is provided with a through hole for placing a camera.
Preferably, the film is a PU film, a leather film, a tree film or a plastic film.
Preferably, the body is made of basalt materials or glass fiber materials.
Preferably, the electronic product housing is applied to a mobile phone or a tablet computer.
The invention also provides a preparation method of the electronic product shell, which comprises the following specific steps:
the method comprises the following steps: preparing a molding material, namely using a prepreg or a prepreg, and performing overlapping according to the thickness requirement of the electronic product shell;
step two: mould shaping is equipped with the surrounding bone structure in the mould, places the type material in the mould to in the mould that designs as required is put into to the prepreg or the prepreg material that will fold and join in marriage, mould shaping condition is: the temperature is 150-180 ℃, the pressure is 3-10 MPA, and the forming time is 2-7 min; the front surface of the formed plate is provided with a surrounding bone;
step three: cutting, namely removing the appearance through CNC machining to form the shape of the shell of the required electronic product;
step four: film pasting, namely selecting a film pasting material according to needs, cutting the raw material of the selected film pasting material according to needs, and aligning the cut film pasting by using a CCD (charge coupled device) machine so that the cut film pasting can be aligned with the plate cut in the third step, and ensuring the accuracy of subsequent film pasting; when the film is pasted, a thermosetting adhesive tape is used, the pasting pressure is 2Kgf-8Kgf, the pasting time is 5s-30s, and the temperature is 90 ℃ -130 ℃, so that the required electronic product shell is formed.
The invention has the following beneficial effects: the edge of the body of the electronic product shell is provided with the arc with the angle of 1-60 degrees, and the edge is provided with the integrally formed surrounding bone, so that the electronic product shell can be seamlessly connected with the body after being pasted with the film, and the beauty of the appearance is ensured. Moreover, the body is made of basalt or glass fiber, so that the novel multifunctional electric heating cooker is durable, does not obstruct signal transmission, and is particularly suitable for being used as a mobile phone, a computer or other electronic equipment. According to the electronic product shell or other electronic product shells prepared by the electronic product shell preparation method, the edge of the attached film is just in the surrounding bone, the height after film attaching is consistent with the height of the surrounding bone, meanwhile, the edge of the film is seamlessly combined with the surrounding bone, and the product after film attaching has the advantages of no bulge or glue failure after being boiled in water for 100 ℃ and 120 minutes, no fracture at 90 ℃ on the front surface and 60 ℃ on the back surface in a bending test, and the drawing force of 50N.
