Embodiment
Following content will be arranged in pairs or groups graphic, and the technology contents of the present invention is described by particular specific embodiment, and the personage being familiar with this technology can be understood other advantage and effect of the present invention easily by content disclosed in the present specification. The present invention also can be implemented by other different specific embodiment or be applied. Every details in this specification sheets also based on different viewpoints and application, under the spirit not deviating from the present invention, can carry out various modification and change.Especially, the proportionlity of each assembly and relative position only have an exemplary use in the drawings, not represent actual state of the invention process.
In addition, in following embodiment, the identical symbol of employing is described by identical or approximation function structure or assembly, and omits the description of identical or impartial technology feature, so that the content disclosed more succinctly and easily understands.
The present invention provides a kind of blind spot key and manufacture method thereof, needs the problem of extra die sinking to solve the making of blind spot key, and each lamina avoiding blind spot to prop up on key cap, use the covered effect promoting each lamina on key cap.
Fig. 1 is the schematic perspective view of blind spot key of the present invention. Fig. 2 is the schematic diagram of the first embodiment of blind spot key of the present invention. Please refer to Fig. 1, Fig. 2, the blind spot key 1 of the present embodiment is located on backlight 2, and includes key cap 11, light shield layer 12, transfer photic zone 13 and the curing gel block 14 as blind spot. Light shield layer 12 is located on key cap 11, has configuration example such as first hollow-out parts 121 of " F ", " J " and " 5 " character pattern. Transfer photic zone 13 is transferred on light shield layer 12; and cover the first hollow-out parts 121 to provide protection; therefore, the backlight of backlight 2 sequentially via key cap 11, first hollow-out parts 121 and transfer photic zone 13, and can illuminate the character pattern in display the first hollow-out parts 121. In addition, transfer photic zone 13, on the predetermined set position of blind spot, is formed with the depression portion for setting curing gel block 14.
In the present embodiment, the depression portion of transfer photic zone 13 can be various structure formation, such as, runs through hole or blind hole, to reach the setting of curing gel block 14. In addition, the depression portion transferring photic zone 13 can be formed in arbitrary region. Citing, as Figure 12 blind spot key of the present invention transfer printing layer cog region the first embodiment shown in, transfer photic zone 13 has multiple circular depression 132, and described circular depression 132 scattering device is in the border of cog region 131 of transfer photic zone 13. Or as Figure 13 blind spot key of the present invention transfer printing layer cog region the 2nd embodiment shown in, transfer photic zone 13 also has multiple circular depression 132, and described circular depression 132 scattering device is in the region intermediate of cog region 131 of transfer photic zone 13. Also or as Figure 14 blind spot key of the present invention transfer printing layer cog region the 3rd embodiment shown in, transfer photic zone 13 has a depression portion 132 in strip, and described depression portion 132 is arranged at the region intermediate of the cog region 131 of transfer photic zone 13. It should be noted that, any region on transfer photic zone 13 surface all may be defined as described cog region 131, the restriction that thus definition position of cog region 131 and shape should do not invented as this case.
About the setting of curing gel block 14, in the present embodiment, the upper end of curing gel block 14 is higher than the upper surface of transfer photic zone 13, owing to there is difference of altitude between the upper end of curing gel block 14 and the upper surface of transfer photic zone 13, thus the position of identification key cap 11 can be come by touching curing gel block 14.
Manufacture method for the present embodiment blind spot key is described below, first, as shown in Figure 4, it is provided that key cap 11. Then, as shown in figs.5 and 6, key cap 11 arranges light shield layer 12, and formed the first hollow-out parts 121 forming character pattern by such as radium technology for fast carving on. , as shown in Figure 7, then transfer photic zone 13 is set on light shield layer 12 by transferring (OMR) technology outside in-mold transfer printing (IMR) or mould.Come again, as shown in Figure 8, transfer photic zone 13 forms depression portion 132 by such as radium technology for fast carving on. Next step, as shown in Figure 9, clicks and enters liquid sizing material above depression portion by dispensing technology, by the flow range of the liquid sizing material of depression portion definition, and solidify to form curing gel block 14 at transfer photic zone 13. Optionally, the liquid sizing material clicked and entered above depression portion can enter depression portion, makes the lower end position of curing gel block 14 in depression portion, and reaches the setting of curing gel block 14.
In addition, in the process that liquid sizing material flows in the scope that depression portion defines, because the relation of surface tension, the surface of liquid sizing material can present circular arc shape so that the surface of curing gel block 14 also can present circular arc shape. The surface shape of liquid sizing material still depends on the composition of liquid sizing material, and should not be limited with circular arc shape.
Fig. 3 is the schematic diagram of the 2nd embodiment of blind spot key of the present invention. please refer to Fig. 3, the blind spot key of the present embodiment and the maximum difference of the first embodiment are, the curing gel block 14 of the present embodiment is selected to be made up of light transmissive material, and light shield layer 12 is in the underface of transfer photic zone 13 cog region 131, it is provided with the 2nd hollow-out parts 122 being positioned at immediately below depression portion, cog region 131 132 in addition, the lower end of curing gel block 14 is made to be arranged in depression portion 132 and the 2nd hollow-out parts 122, so, the backlight of backlight 2 can sequentially via key cap 11, 2nd hollow out layer 122 and depression portion 132, and illuminate and show the curing gel block 14 as blind spot, to meet the demand of touch system person.
Moreover, about the manufacture method of blind spot key, the present embodiment and the maximum difference of the first embodiment are: as shown in Figure 10, the present embodiment after the depression portion 132 of transfer photic zone 13 is formed, also by the light shield layer 12 of such as radium technology for fast carving on immediately below depression portion 132 forms the 2nd hollow-out parts 122. In addition, as shown in figure 11, the liquid sizing material clicked and entered above depression portion 132, except entering depression portion 132, also can enter the 2nd hollow-out parts, makes curing gel block 14 lower end position in depression portion and the 2nd hollow-out parts, uses the light display reaching curing gel block 14.
In sum, the present invention forms blind spot by the lamina of dispensing technology on key cap, and blind spot thus can be avoided to affect the covered effect of lamina on key cap. In addition, lamina on key cap is formed with depression portion in the predetermined set region of blind spot, use and limit for the formation of flow range on key cap of the liquid sizing material of blind spot, so, can guaranteeing the suitable position that blind spot is formed on key cap, thus the making of blind spot key does not need additionally to prepare ejection shaping die.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the present invention.
