specific Embodiment approach 1

[0035] The manufacturing process of the electronic product casing, the present embodiment takes the manufacturing process of the back cover of the mobile phone as an example, including the following steps:

[0036] Step 1: Prepare the explosion-proof membrane, including:

[0037] (A) Process the basic explosion-proof film with OCA optical adhesive to obtain the required explosion-proof film, including:

[0038] (A1) UV drawing transfer printing on the basic explosion-proof film with OCA optical adhesive;

[0039] (A2) The non-OCA surface of the explosion-proof film obtained in A1 is placed on a UV wire drawing die covered with UV liquid, the roller is pressed evenly, and the texture on the UV die is transferred to the explosion-proof film;

[0040] (A3) the anti-explosion film obtained in A2 is subjected to UV light irradiation and cured to form a stable texture;

[0041] (B) electroplating the explosion-proof film after UV transfer printing in A to form a coating layer;

specific Embodiment approach 2

[0061] The main difference between the second embodiment and the first embodiment is:

[0062] (1) In this embodiment, in H, the explosion-proof film and the back cover of the mobile phone are laminated. According to actual needs, the back cover of the mobile phone can be heated or laminated at normal temperature.

[0063] (2) In this embodiment, in J, if the defoaming treatment is multi-stage, the multi-stage is four stages.

[0064] Specifically, the specific settings of the four-stage high-pressure deaerator include: stage 1, pressure 1600±200KPA, temperature 50±10°C, time 10min±5min; stage 2, pressure 1500±100KPA, temperature 45±10°C, time 8min ±3min; stage 3, pressure 1300±100KPA, temperature 35±10℃, time 8min±3min; stage 4, pressure 1000±100KPA, temperature 30±10℃, time 4min±2min.

[0065] (3) In this embodiment, after the J treatment, the adhesion between the back cover of the mobile phone and the explosion-proof film is 20N.

[0066] (4) In this embodiment, the posit...

[0067] The main differences between the third embodiment and the second embodiment are:

[0068] (1) In this embodiment, in H, the explosion-proof film and the back cover of the mobile phone are laminated, and in this embodiment, the back cover of the mobile phone is laminated under heating.

[0069] (2) In this embodiment, in J, the defoaming treatment is multi-stage, and the multi-stage is four stages.

[0070] Specifically, the specific settings of the four-stage high-pressure deaerator include: stage 1, pressure 1600±200KPA, temperature 50±10°C, time 10min±5min; stage 2, pressure 1500±100KPA, temperature 45±10°C, time 8min ±3min; stage 3, pressure 1300±100KPA, temperature 35±10℃, time 8min±3min; stage 4, pressure 1000±100KPA, temperature 30±10℃, time 4min±2min.

[0071] (3) In this embodiment, after the J treatment, the adhesion between the back cover of the mobile phone and the explosion-proof film is 15N.

Abstract

According to the electronic product shell manufacturing technology, compared with an existing product, the produced electronic product shell is small in electronic signal interference, good in impact resistance and low in price, and meanwhile various shapes and colors can be manufactured according to market requirements. According to the invention, the UV wiredrawing is adopted to transfer the texture, the coating layer is adopted, and the ground color is printed on the coating layer; and the three structural layers can realize the color effects of single color, darkness, gradient color, high-brightness dazzling color, high-brightness color, high-brightness gradient color and multiple colors including but not limited to partition colors in a manner of combining the three structural layers according to the required color effect. And the problem of a combination gap between the explosion-proof membrane and the shell of the electronic product after traditional attachment is solved by adopting laser etching of the explosion-proof membrane, attachment of the bearing membrane, attachment of the positioning device and CNC machining treatment. A series of problems in the manufacturing process of an existing electronic product shell are solved.

Description

technical field [0001] The invention relates to the field of glass thinning, in particular to a manufacturing process of an electronic product casing. Background technique [0002] At present, most electronic product casings in the market, (1) in terms of product structure, such as mobile phones, tablet computers, display screens and other casing products are metal casings, glass casings, injection molding single-product casings, ceramic casings, etc. (2) In terms of product design: At present, the injection molding 3D product drawings designed outside the market do not consider the post-manufacturing process, and the product design structure is single, which makes it impossible to carry out the combination of multiple processes such as curtain coating, lamination, printing, and CNC blanking. , The product performance is single, and the design use is limited. (3) In the production of compression injection molds: At present, the molds are developed outside, the mold structur...
