Description
Technical field
It the utility model is related to a kind of backlight detection tool.
Background technology
Cell phone back tabula rasa needs to detect its luminous component before fitting together with display screen, touch-screen, passes through
Tool makes backlight light, and whether artificial detection luminous component is luminous normal, if has white point, stain, light leak, bright border, cut
Etc..Weak point is that this tool includes clamping bench and battery pack, and battery pack is directly connected with backlight provides power supply, battery
Group needs to charge after being finished electricity using amount of batteries decline, electric current and spread of voltage after a period of time, and this battery pack
It can just reuse；The electric current and voltage of battery pack are sometimes unstable；For artificial detection white point and cut, due to white point and draw
Trace sends white brightness with normal close, and artificial easily missing inspection or flase drop, the accuracy rate of detection are low.
Utility model content
A kind of the utility model overcome the deficiencies in the prior art, there is provided cell phone back tabula rasa white point scratch detection tool.
It is achieved through the following technical solutions above-mentioned purpose：
A kind of cell phone back tabula rasa white point scratch detection tool, including backlight clamping plate, power supply adaptor, it is arranged on backlight
Horizontal active grab on plate clamping plate, the lower circuit wafer being arranged in backlight and it is arranged on backlight clamping plate
The blue-ray light of side, the chuck of the horizontal active grab are provided with upper circuit wafer, the lower circuit wafer and the upper circuit wafer shape
Into jaws, the top surface of the lower circuit wafer is provided with cathode contact, and the bottom surface of the upper circuit wafer is provided with and the cathode contact phase
Corresponding cathode contact, the cathode output end of the power supply adaptor are connected with the cathode contact, the power supply adaptor
Cathode output end is connected with the cathode contact.
Operation principle of the present utility model is as follows：Backlight is placed on backlight clamping plate, the power supply of backlight is arranged
Line is placed in circuit wafer and lower circuit wafer is formed in jaws, jaws tighten the power supply winding displacement for making backlight electrode input end and
Negative input is connected and is fixedly clamped with cathode contact and cathode contact respectively, and power supply adaptor passes through cathode contact and negative pole
Contact provides current to the power supply winding displacement of backlight, makes backlight shinny and to open blue-ray light white to detect against backlight irradiation
Point and cut.
The beneficial effects of the utility model are：Compared with prior art, the outputting current steadily of power supply adaptor, that is, insert i.e.
With very convenient；Backlight is shinny and then opening blue-ray light is irradiated to it, and people is seen in the normal shinny part of backlight
To be light blue, and the light of white point and cut is combined into more shallow blue light with blue light, and compared with prior art, this is easy to differentiate white point
Come out with cut, be not in the situation of missing inspection and flase drop, improve the accuracy rate of detection.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is the positional structure schematic diagram of circuit wafer and lower circuit wafer on the utility model.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing：
Shown in Fig. 1 to Fig. 2, a kind of cell phone back tabula rasa white point scratch detection tool, including backlight clamping plate 1, power supply are fitted
Orchestration 2, the horizontal active grab 3 being arranged on backlight clamping plate, lower circuit wafer 4, the Yi Jishe being arranged in backlight
The blue-ray light 5 above backlight clamping plate is put, the chuck 31 of the horizontal active grab 3 is provided with upper circuit wafer 32, described
Lower circuit wafer 4 forms jaws with the upper circuit wafer 32, and the top surface of the lower circuit wafer 4 is provided with cathode contact 41, the upper electricity
The bottom surface of road piece 32 is provided with the cathode contact 321 corresponding with the cathode contact 41, the positive pole output of the power supply adaptor 2
End is connected with the cathode contact 321, and the cathode output end of the power supply adaptor 2 is connected with the cathode contact 41.
Operation principle of the present utility model is as follows：Backlight is placed on backlight clamping plate, the power supply of backlight is arranged
Line is placed in circuit wafer and lower circuit wafer is formed in jaws, jaws tighten the power supply winding displacement for making backlight electrode input end and
Negative input is connected and is fixedly clamped with cathode contact and cathode contact respectively, and power supply adaptor passes through cathode contact and negative pole
Contact provides current to the power supply winding displacement of backlight, makes backlight shinny and to open blue-ray light white to detect against backlight irradiation
Point and cut.
It the above is only preferred embodiment of the present utility model, the scope of protection of the utility model is not limited merely to above-mentioned
Embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should be pointed out that pair
For those skilled in the art, some improvements and modifications under the premise of the utility model principle is not departed from,
It should be regarded as the scope of protection of the utility model.
