Description
Technical field
The utility model relates to liquid crystal display technical field, is specifically related to a kind of liquid crystal display lighting defect detecting system.
Background technology
The production run of liquid crystal display comprises nearly hundred procedures, although most of operation of liquid crystal display completes in dust free room, inevitably shows the defects of vision that some dust particles cause.Normally carry out image acquisition by facing camera, this limitation facing camera is that cannot collect side-looking observes class defect image, particularly scratch for backlight, backlight is rolled into a ball in vain, show the side-looking observation class defects such as colour cast, traditional detection mode adopts the detection method of artificial vision to go to detect this kind of defect, affect by subjective factor, situation that is undetected and flase drop is easily there is in testing process, 100% detection cannot be realized, cause that detection speed is slow, detection efficiency is low, have impact on whole detection speed and detection efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of liquid crystal display lighting defect detecting system, can detect the side-looking class defect of liquid crystal display to be detected.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
The utility model provides a kind of liquid crystal display lighting defect detecting system, and described system comprises image collecting device, stationary installation, lighting jig microscope carrier and industry control unit;
Described image collecting device is installed in described stationary installation, described image collecting device comprises two side-looking cameras to gather the image information of the liquid crystal display different angles to be detected be installed on lighting jig microscope carrier respectively, and described image collecting device is electrically connected with described industry control unit.
The beneficial effects of the utility model are: by increasing side-looking camera on checkout equipment, gather the image information of the different angles of liquid crystal display to be detected, can detect the side-looking class defect of liquid crystal display to be detected, such as, the longitudinal direction of liquid crystal display to be detected scratches defect and the upper left corner scratches defect.Compared with prior art, the interpolation of side-looking camera, solves the test problems that the defects such as class are observed in side-looking, reduces loss and false drop rate, improve product percent of pass.Meanwhile, the interpolation of side-looking camera instead of traditional with the naked eye detection side that makes specially and looks the method for class defect, improves detection efficiency, greatly reduces production cost simultaneously.
Accompanying drawing explanation

In accompanying drawing, the list of parts representated by each label is as follows:
1, the first support bar, the 2, second support bar, the 3, the 3rd support bar, 4, forward sight camera, 5, right frontly look camera, 6, tool microscope carrier, 7, liquid crystal display to be detected.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Embodiment, a kind of liquid crystal display lighting defect detecting system.Below in conjunction with Fig. 1, the detection system that the present embodiment provides is described in detail.
See Fig. 1, the system that the present embodiment provides comprises image collecting device, stationary installation, lighting jig microscope carrier 6 and industry control unit; Described image collecting device is installed in described stationary installation, described image collecting device comprises two side-looking cameras to gather the image information of liquid crystal display to be detected 7 different angles be installed on lighting jig microscope carrier 6 respectively, and described image collecting device is electrically connected with described industry control unit.
Wherein, described lighting jig microscope carrier 6 comprises at least one fixture, and this fixture is used for being fixed a kind of liquid crystal display to be detected 7 of size.Described stationary installation comprises the first support bar 1, second support bar 2 and the 3rd support bar 3, wherein, described first support bar 1, the 3rd support bar 3 and the second support bar 2 successively head and the tail are fixedly linked, and described first support bar 1 and the second support bar 2 are vertically placed, described 3rd support bar 3 horizontal positioned.
Described side-looking camera comprises forward sight camera 4 and right frontly looks camera 5, described forward sight camera 4 and to be describedly right frontly all fixedly installed on described 3rd support bar 3 depending on camera 5.Level angle between described forward sight camera 4 and detected liquid crystal display 7 is between 30 ° to 60 °, and is 350mm with detected liquid crystal display 7 near-end air line distance.Described right front be between 30 ° to 60 ° depending on the level angle between camera 5 and detected liquid crystal display 7, and be 350mm with detected liquid crystal display 7 near-end air line distance.
The specific works process of the detection system of liquid crystal display lighting defect adopting the present embodiment to provide is: image collector is set to side-looking camera, comprises forward sight camera and right frontly looks camera.The image information of forward sight collected by camera liquid crystal display regulation of longitudinal angle to be detected, and send it to master control unit; Right front image information of looking the collected by camera liquid crystal display upper left corner to be detected, and send it to master control unit.The image information of the liquid crystal display regulation of longitudinal angle to be detected taken according to forward sight camera by industry control unit and right front image information of looking the liquid crystal display upper left corner to be detected of camera shooting, determine that the longitudinal direction of liquid crystal display to be detected scratches the upper left corner caused in defect and artificial organ backlight process and scratches defect, and then detect the side-looking class defect of liquid crystal display to be detected.
A kind of liquid crystal display lighting defect detecting system that the utility model provides, by increasing side-looking camera in the stationary installation of detection system, gather the image information of the different angles of liquid crystal display to be detected, the side-looking class defect of liquid crystal display to be detected can be detected, such as, the longitudinal direction of liquid crystal display to be detected scratches defect and upper left corner scuffing defect.Compared with prior art, the interpolation of side-looking camera, solves the test problems that the defects such as class are observed in side-looking, reduces loss and false drop rate, improve product percent of pass.Meanwhile, the interpolation of side-looking camera instead of traditional with the naked eye detection side that makes specially and looks the method for class defect, improves detection speed and detection efficiency, greatly reduces production cost simultaneously.
