Abstract
The invention provides a mobile phone keyboard light guide plate with a metal spring piece, which comprises a plate body. The back of the plate body is printed with light guide points which are cylindrical protrusions made of light guide printing ink. The light guide plate is characterized in that the back of the body of the light guide plate is adhered with the metal spring piece; and the metal spring piece is adhered with the body through water-gel printing ink printed on the outer layer of the light guide points. The body of the light guide plate is a PU plate or a PC plate. The metal spring piece is in a circular shape. The invention also provides a process for producing the mobile phone keyboard light guide plate with the metal spring piece. A PET layer between the light guide plate and the metal spring piece is not required, so the overall thickness of the light guide plate is reduced, the contact between the keyboard and the spring piece is more direct, and the hand feels of pressing between the keyboard and the spring piece are improved. Moreover, the light guide plate is suitable for making thinner mobile phones and meets the market demands.
Description
Affiliated technical field
The present invention relates to a kind of mobile phone press key light guide plate and production technology thereof, particularly a kind of mobile phone press key light guide plate and production technology thereof with metal clips.
Background technology
In mobile phones design, distinguish each function key of mobile phone and shown content for making it at night and dark place, lighting device need be installed.
Existing mobile phone module 1, as shown in Figure 1, LED lamp 2, switch 3 and metal clips 4 are installed on the PCB/FPC plate 1, and order is equipped with guide pillar 6 and button 7 above metal clips 4.When the user pushes button 7 the time, make it to contact by guide pillar 6 and metal clips 4 with switch 3 on the pcb board 1, circuit turn-on produces signal, LED lamp 2 starters, its irradiation light of sending is directly thrown light on to button 7 in the mode of point.Employing is thrown light on to button in the mode of point, then needs to use a large amount of LED lamps to be evenly distributed on each orientation of keyboard, could guarantee that keyboard is luminous even and briliancy is high everywhere, and common LED lantern festival is used 6-8.But LED lamp usage quantity is too much, thereby can consume the working time that lot of energy has reduced battery greatly because of needs, causes the cell phone standby time short, and LED lamp usage quantity too much also can increase production cost simultaneously.
For addressing this problem, in some mobile phone module, add light guide plate, constitute existing mobile phone module 2, as shown in Figure 2, in guide pillar 6 and 4 addings of shell fragment light guide plate 5 of mobile phone module, because the light that light guide plate 5 can be sent light source reflects, therefore only need to install a spot of LED lamp, promptly be less than 6 and just can produce good illuminating effect, conserve energy reduces production costs.But in module, add one deck structure, can make product one-piece construction thickening, and also have 11 layers of PET (mylar) between metal clips 4 and the light guide plate 5, mobile phone is not easy to do thin, can not meeting the market requirement, i.e. the trend of mobile phone thickness attenuation can also reduce the feel of pushing of button and shell fragment simultaneously.
Summary of the invention
The invention provides a kind of mobile phone press key light guide plate with metal clips, purpose is to solve the prior art problem, and a kind of use amount that can reduce the LED lamp is provided, the light guide plate of the reduction thickness that metal clips and light guide plate can be united two into one again.

(b) adjust net apart between 3-5mm, pressure is between 5-6N;
(c) light guide ink is transferred on the PU/PC plate by printing, the printing thickness of the each printing of control, promptly the leaded light dot thickness is consistent it, and its printing thickness is selected between 10-15 μ;
(d) the PU/PC plate that will print light guide ink toasts drying in infrared heating heating furnace, and baking temperature is controlled between 70-80 ℃, and stoving time is at 80-90s;
(e) glue printing ink is transferred to by printing is printed with on light guide ink and the dry good PU/PC plate of baking, the printing thickness of the each printing of control, promptly the glue ink thickness is consistent it, and its printing thickness is selected between 18-22 μ;
(f) the PU/PC plate that will print glue printing ink toasts drying in infrared heating heating furnace, and the control baking temperature is between 70-80 ℃, and stoving time is at 80-90s;
Four), that drying is good light guide plate is towards pilot hole;
Five), the relevant position according to keyboard is stained with metal clips on the light guide plate of glue printing;
Six), the five metals stamping goes out product design.
Dry good light guide plate adopts CCD towards pilot hole
Beneficial effect of the present invention: save pet layer between light guide plate and the metal clips, reduced integral thickness, not only made button more direct, improved the feel of pushing of button and shell fragment with contacting of shell fragment, more be applicable to simultaneously and make thin mobile phone, adapt to market demand.
