Description of drawings
Fig. 1 is the structural representation of the embodiment one of the utility model module detecting device backlight.
Fig. 2 is the structural representation of the embodiment two of the utility model module detecting device backlight.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.
Embodiment one:
As shown in Figure 1, the utility model module detecting device backlight comprises a base platform 1 and a cover plate 2.Cover plate 2 interconnects through a fixed mechanism and base platform 1.Between present embodiment cover plate 2 and the base platform 1 for being rotationally connected; Wherein said fixed mechanism comprises two cover plate holders 23 that are fixed on the base platform 1, makes the two ends of cover plate 2 realize being rotationally connected with corresponding cover plate holder 23 through a rotating shaft 24 respectively.Adopting between said cover plate and the said base platform is rotationally connected makes one-piece construction link up, easy to operate, and the position of said cover plate during with the applying of said base platform is more accurate, has improved operating efficiency.
On base platform 1, be provided with at least one flexible PCB connector 11.Number and position for flexible PCB connector 11 do not have concrete restriction, are example with a flexible PCB connector 11 in the present embodiment.On base platform 1, also be provided with at least one detent mechanism, said detent mechanism is mainly used in horizontal fixed one module 3 backlight.After module 3 backlight is put into said detent mechanism; Make the flexible PCB of module 3 backlight be placed on the flexible PCB connector 11 places top of flexible PCB connector 11 (or be positioned at); Guarantee can to make after cover plate 2 and base platform 1 pressing flexible PCB and the flexible PCB connector 11 of module 3 backlight to compress with this and electrically contact, thereby through external flexible PCB connecting line 4 conductings module 3 backlight.Detent mechanism described in the present embodiment comprises that one is opened in the groove backlight 12 on the base platform 1, and is around in the locating part 13 of groove backlight 12 edges.Being provided with of locating part 13 helps fixing module 3 backlight, prevents that module 3 backlight from shifting out said groove backlight.Because the pliability of foam is better, acquisition and cost are low easily, can play good protective action to module 3 backlight, so locating part 13 are preferably some foam pieces or foam bar.Certainly, groove 12 backlight also can be parts independently, and is fixed on the base platform 1, and such structure can play same effect, does not do here and gives unnecessary details (not shown).
On cover plate 2, be provided with at least one flexible PCB pressing plate 22 and at least one pressing plate 21 backlight.In like manner, there is not concrete restriction for the number of flexible PCB pressing plate 22 and pressing plate 21 backlight, corresponding flexible PCB connector 11 in the present embodiment, adopting a flexible PCB pressing plate 22 and a pressing plate 21 backlight is example.When cover plate 2 is pressed on 1 last time of base platform, flexible PCB pressing plate 22 and corresponding flexible PCB connector 11 coupling pressings, and also pressing plate backlight 21 matees pressings with the interior module backlight 3 of corresponding said detent mechanism.The flexible PCB pressing plate 22 here can select for use foam to process, and plays the effect of pushing, and makes the flexible PCB conducting.
Because different modules backlight has different thickness, preferably, in groove 12 backlight, is lined with at least one liner backlight, can adopt soft foam to process.Said liner backlight the height that on the one hand helps to regulate module backlight is set, on the other hand protective effect has been played in the bottom of module backlight, prevent that module backlight is impaired because of pushing.
In addition, the acrylic board of the material preferably clear of pressing plate 21 backlight.Certainly cover plate 2 and cover plate holder 23 equally also can adopt transparent acrylic to process.The operating personnel that are more convenient for like this observe surface backlight, need not extra employing aid.
The concrete use of the utility model module detecting device backlight that is obtained by said structure is following: at first, flexible PCB connector 11 and flexible PCB connecting line 4 are connected, connected constant-current supply.Then; Module backlight 3 to be detected is put into groove 12 backlight; And adjust the liner quantity backlight in the groove 12 backlight as required, module 3 backlight is positioned on the said liner backlight, and the flexible PCB of module backlight 3 lies in a horizontal plane in flexible PCB connector 11 places.Then, cover cover plate 2, pressing plate 21 backlight is aimed at compressed module 3 backlight.Simultaneously, flexible PCB pressing plate 22 compresses on the flexible PCB of module 3 backlight, makes module 3 conductings backlight.Module 3 backlight like this will be lighted luminous.When pressing cover plate 2, can detect module backlight surface through pressing plate 21 backlight (employing transparent material) and whether have problems such as stain, white point.Like this, problematic product will be detected by said pick-up unit.
Embodiment two:
As shown in Figure 2, the structure of present embodiment module detecting device backlight is basic identical with embodiment one, and its difference is: said fixed mechanism is a fixed support, and it comprises at least four pillars 5 that are vertically fixed on the base platform 1.Simultaneously, correspondence is provided with at least four perforation on the cover plate 2.Having no particular limits for the perforation and the number of pillar, is example with four pillars and four corresponding perforation in the present embodiment, and the size of boring a hole and the diameter of pillar are complementary.Cover plate 2 is located on the pillar through said perforation, and on every pillar 5, adopts a secure component (not shown) to fix cover plate.Secure component is preferably a jump ring, anchor clamps or a register pin.Adopt this fixing rack structure in the present embodiment, can guarantee that the level of cover plate 2 presses down, produce deviation when more effectively preventing cover plate 2 with base platform 1 pressing.
In sum, the utility model module detecting device backlight is simple in structure and easy to operate, bad problem such as can detect normal module detecting device backlight can't detected dust, foreign matter.In addition, it can also be pinpointed the problems effectively in advance, avoids at product more loss taking place.
Though more than described the embodiment of the utility model, it will be understood by those of skill in the art that these only illustrate, the protection domain of the utility model is limited appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite of principle that does not deviate from the utility model and essence, but these changes and modification all fall into the protection domain of the utility model.
