In present embodiment, the film 13 of covering can be PET film, and the film 13 of covering is to the He of lateral surface 121
The step surface 122 is protected.The film 13 of covering is completely covered by the lateral surface 121 and the step surface 122, so as to anti-
Only the lateral surface 121 and the step surface 122 are coated with anti-fingerprint film, and then prevent the lateral surface 121 and the step
The roughness in face 122 reduces, and then prevents that the lateral surface 121 and the adhesive strength of the step surface 122 are relatively low, so as to improve
The bond strength of transparent panel 10 and the frame 20 is stated, after plating sets the anti-fingerprint film 131 in the upper surface 111, is torn
It is described to cover film 13, continue to process on the step 12 to facilitate.In other embodiments, it is described cover film 13 can also
It is hard transparent plate, the step surface 122 and the lateral surface 121 is covered with facilitating.
Step S05：Coarse processing is carried out to the lateral surface 121 and the step surface 122.
In present embodiment, tear it is described cover film 13 after, etch process can be used to the lateral surface 121 and described
Step surface 122 etches decorative pattern, to increase the roughness of the lateral surface 121 and the step surface 122, so as to increase the outside
Face 121 and the reinforcing degree bonding with viscose glue of the step surface 122, and then it is bonding with frame 20 strong to improve the transparent panel 10
Degree, to improve the production yield of the housing unit moulding process.In other embodiments, can also be using Milling Process
Mode mill out coarse decorative pattern on the lateral surface 121 and the step surface 122, to increase the step surface 122 and institute
State the roughness of lateral surface 121.
Step S06：Groove 123 is processed on the step surface 122 and the lateral surface 121.
Can use CNC milling machine equal milling on the lateral surface 121 and the step surface 122 in present embodiment
Go out the groove 123 or the groove 123 is gone out using optics grinding machine.The section of the groove 123 is in semicircle
Shape.In other embodiments, the groove 123 can also be rectangular recess, and the number of the groove can also be multiple；Institute
It can also be after the step S04 to state step S06, implemented before the step S05.
Step S07：The lateral surface 121 is covered at the upper surface 111 with film 14.

100 presentation qualities improve.In other embodiments, the outer surface 23 can also be sets with the upper surface 111 in angle
Put, to increase the narrow side visual effect of the housing unit 100.
Step S11：Common plating sets functional membrane 30 on the outer surface 23 and the upper surface 111.
In present embodiment, outer surface 23 and the transparent panel 10 of the frame 20 is completely covered in the functional membrane 30
Upper surface 111.The functional membrane 30 is anti-reflection film, so as to improve the light transmission of the housing unit 100, improves experience
Property.In other implementations, the functional membrane 30 can also be rupture pressure disc, or frosted film.
Step S12:Deviate from the side ink for screen printing layer 17 of upper surface 111, the ink layer in the transparent panel 10
The orthographic projection region of the 17 coverings step surface 122 and the medial surface 21 on the ink layer 17.
In present embodiment, the ink layer 17 is white ink, utilizes the relatively described step surface 121 of the ink layer 17
Set, so that the ink layer 17 can be to blocking inside housing unit 100, and then avoid the transparent panel 10
Through and reflect the internal light of housing unit 100, and then avoid because of visual difference effect caused by refraction, it is described so as to improve
The performance of housing unit 100, and then cause the housing unit moulding process to improve product quality.In other embodiment
In, the ink layer 17 can also be black ink.
Step S13：In the transparent panel 10 optical cement layer 40 is coated with away from the side of upper surface 111.Using described
Optical cement layer 40 can be bonded display panel, and have no effect on the translucency of the housing unit 100.
Step S14：One display panel 50 is provided, the display panel 50 is adhered to the optical cement layer 40 away from described
The side of transparent panel 10.
The display panel 50 is bonded on the transparent panel 10, increases the use function of the housing unit 100, carries
The suitability of the high housing unit 100.In present embodiment, display panel 50 can be LCD (Liquid Crystal
Display, liquid crystal flat panel display) liquid crystal display or LCM (LCD Module, liquid crystal display die set) component.Display surface
Plate 50 especially can be wide variety of touch screen, such as the display panel 50 can be that touch control layer is embedded into liquid crystal pixel
In-cell touch screens or touch control layer be arranged at on-cell touch screens on liquid crystal pixel, can also be touch control layer
The complete full sticking touch control screen for fitting in cover plate.
The housing unit moulding process of the present invention, by providing the translucent plate member with flat upper surface, so that institute
The matching precision for stating translucent plate member and die cavity is improved, and then the outer framework is integrally formed out around the translucent plate member, profit
With the outer framework top surface and the upper surface flush, so as to improve the Forming Quality of the outer framework, then to described outer
Framework and the translucent plate member carry out milling, so as to facilitate smooth first outer surface to connect of milling and second appearance
Face, the housing unit being made up of the frame and the transparent panel finally being obtained, the housing unit presentation quality improves, from
And the production efficiency of the housing unit moulding process is improved.
Above is the preferred embodiment of the present invention, it is noted that for those skilled in the art,
Under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as this hair
Bright protection domain.
