Description of the drawings
Fig. 1 is a kind of display screen roll screen structure of the detecting device schematic diagram proposed by the present invention；
Fig. 2 is display screen subsection domain schematic diagram in the present invention.
Specific implementation mode
Referring to Fig.1, a kind of display screen roll screen detection device that present embodiment proposes, including：Grip slipper 1, lifting seat 2,
Pressure roller 3, camera, image mosaic module and image judgment module.
Grip slipper 1 is for being clamped display screen to be detected.Specifically, grip slipper 1 is equipped with the peace being consistent with display screen shape
Tankage, and installation trench bottom is equipped with the support that one piece can move up and down and multiplies plate.Display screen to be detected can be mounted on mounting groove in into
Row screens, multiplying plate by support can push the display screen A in mounting groove to move upwards disengaging mounting groove, to be convenient for changing display screen
It is detected.
Lifting seat 2 is equipped with the guided way for being parallel to horizontal plane, and pressure roller 3 is on guided way and can come along guided way
Rollback is dynamic.Lifting seat 2 can move up and down with dynamic pressure roller 3.It is equipped on grip slipper 1 in the state of display screen to be detected, pressure roller 3 exists
Movement locus on horizontal plane coincides with display screen, and pressure roller 3 is as the up and down motion of lifting seat 2 is against display screen or remote
From display screen.Specifically, in present embodiment, pressure roller can realize two states.
Under first state, display screen A is mounted in mounting groove and is positioned, and pressure roller 3 compresses display screen and along guided way
It rolls around, i.e., pressure roller 3 on a display screen squeezes display screen to roll.Under second state, pressure roller 3 is with lifting seat 2
Grip slipper 1 is risen away from, it is convenient that installation or discharging are carried out to display screen.
Camera is used to obtain the image of display screen A under first state.
Sectional drawing time threshold and sectional drawing width threshold value are preset in image mosaic module, image mosaic module often passes through sectional drawing
Time threshold obtains shooting image from camera, and the display image of pressure roller both sides is intercepted according to sectional drawing width threshold value, when
Pressure roller 3 passes through entire display screen, and image mosaic module splices the 3 both sides sectional drawing of pressure roller of acquisition respectively, before being pressed
Side display image and pressing rear side display image.In present embodiment, front side refers to the side of Shunzi's pressure roller rotating direction, after
Side refers to away from the side of pressure roller rotating direction.And in present embodiment, in order to avoid pressure roller 3 hinders the shooting work of camera,
The quantity of camera is two, and two cameras are separately mounted to the opposite both sides of 3 movement locus of pressure roller.Image mosaic module
Front side display is pressed according to the shooting image mosaic of two cameras, that is, pressure roller front side camera and pressure roller rear side camera respectively
Screen image and pressing rear side display image.
With reference to Fig. 2, in present embodiment, display screen screen can be divided into ABCDEFGHIJKM totally ten Two Areas, pressed
Roller 3 passes through this 12 regions successively during squeezing display screen.When pressure roller 3 is located at a-quadrant, image mosaic module is according to camera
Shoot image interception B area image；When pressure roller 3 is located at B area, image mosaic module shoots the areas image interception A according to camera
Area image and C area images；When pressure roller 3 is located at the regions C, image mosaic module shoots image interception B area figure according to camera
Picture and D area images；And so on, when pressure roller 3 is located at the regions K, image mosaic module shoots the areas image interception J according to camera
Area image and M area images；When pressure roller 3 is located at the regions M, image mosaic module shoots image interception J administrative division maps according to camera
Picture.
In present embodiment, in pressure roller squeezes ABCDEFGHIJK region process successively, image mosaic module is according to pressure roller
Image and composition the pressing front side in totally ten one regions the corresponding interception BCDEFGHIJKM of shooting image of 3 front side cameras are aobvious
Display screen image；In pressure roller squeezes BCDEFGHIJKM region process successively, image mosaic module is according to 3 rear side camera of pressure roller
Shooting image it is corresponding interception ABCDEFGHIJK totally ten one regions image and composition pressing rear side display image.
In present embodiment, the regions ABCDEFGHIJK are divided according to sectional drawing width threshold value, when it is implemented, in order to
The screenshot area of guarantee each time has received the pressure effect of pressure roller, and sectional drawing width threshold value should be greater than being equal to 3 radius of pressure roller simultaneously
Less than or equal to 3 diameter of pressure roller.In order to facilitate image mosaic, in present embodiment, display screen is parallel to 3 horizontal movement direction of pressure roller
Length be 3 radius length of pressure roller integral multiple, concretely pressure roller radius or diameter.
Image judgment module is connect with image mosaic module, according to pressing front side display image and pressing rear side display
Screen image judges to whether there is foreign matter in display screen.
In present embodiment, under first state, full frame extruding, image mosaic mould are carried out to display screen in pressure roller rolling process
Root tuber carries out shearing splicing according to the relative position of pressure roller 3 and display screen to display image, obtains under full screen pressured state
Display screen detection image avoids and detects mistake caused by display screen foreign matter existence position is not pressurized, is conducive to improve display screen
The precision of foreign bodies detection.In present embodiment, image judgment module according to display screen detection image judge inside display screen whether
There are foreign matter, i.e. image judgment module is judged according to general image, relative to the real-time judge that display screen single-point is pressurized, is carried
The high efficiency of display screen foreign bodies detection.
In present embodiment, according to the camera of 3 front and rear sides of pressure roller, after obtaining pressing front side display image and pressing
Side display image judges display screen twice as foreign matter basis for estimation, further improve judging efficiency, also carry
High judgement precision.It is worth noting that, former and later two extreme regions A, M of display screen are only capable of being judged once.
In present embodiment, in order to avoid the foreign matter outside display screen impacts the judgement of its inside foreign matter, pressure roller 3
On in axial direction outside week at least provided with one for adhering to the stick of foreign matter, alternatively, 3 periphery of pressure roller is coated with for gluing
The stick of attached foreign matter.In this way, during pressure roller 3 squeezes display screen, foreign matter outside display screen is moved with stick, to pass through
The movement of foreign matter position can exclude the foreign matter on the outside of display screen, improve the precision of foreign bodies detection on the inside of display screen.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
