A kind of full automatic liquid crystal display outward appearance general detection device with printing opacity detection function is present embodiments provided, should
Device structure is as shown in figure 1, illustrate the testing process of the equipment with reference to device structure.Equipment includes conveying device 108, determined
Position device, second conveyer 109, reverse side test section 110, second conveyer 111, front test section 112, printing opacity detection dress
Put 113 and the data processing division positioned at backstage.It is not drawn on the subsidiary positioner figure of conveying device 108, is parallel to liquid crystal
Shield four pieces of baffle plates of 101 4 sides setting, liquid crystal display 101 is moved to behind localization region by conveyer belt, and baffle plate can promote liquid crystal display 101
Predeterminated position is limited to, whole liquid crystal display 101 is covered when test section is taken pictures after facilitating and illumination is good；Afterwards, utilize
Motor driving drops to the sucker 102 of second conveyer 109 to contact with the surface of liquid crystal display 101, using with the phase of vacuum tube 103
Vavuum pump even vacuumizes the inner chamber of sucker 102, so as to make liquid crystal display 101 be fixed with sucker 102 using negative pressure；Then, motor
Liquid crystal display 101 is taken away conveyer belt by driving, and is further moved horizontally to reverse side test section detection work along first straight line motor 104
Position；Camera completion is taken pictures after process, and reverse side test section transfers data to data processing division after obtaining the back side image of liquid crystal display 101
Handled, data processing division is calculated graph data by image processing software, utilize surface defect such as cut, stain
Difference in picture contrast, tells the defect situation on surface；Second conveyer 109 is entered while completing to shoot step
One step drive liquid crystal display move right to the delivery position of second conveyer 111, now, the motor of second conveyer 109 drive
It is dynamic that liquid crystal display 101 is dropped into the carrier-table surface of second conveyer 111, open vacuum valve 106 plummer inner chamber is vacuumized,
The vavuum pump of sucker 102 is simultaneously closed off, is adsorbed liquid crystal display 101 in carrier-table surface by first through hole 105, sucker 102 is put
Liquid crystal display 101 is opened, motor driving plummer is moved to front test section station along second straight line motor 107；Similarly, front inspection
Survey portion shoots the direct picture of liquid crystal display 101 and is sent to data processing division analysis detection；Complete after shooting, second conveyer
111 continue to drive liquid crystal display to be moved to the station of transmittance tester 113 along second straight line motor 107, shoot the printing opacity of liquid crystal display 101
The backlight image in portion, is uploaded to data processing division and is calculated, so as to complete whole outward appearance testing processes.
In order that the plummer of second conveyer 111 preferably completes to carry, absorption and printing opacity detecting step, this reality
Plummer in example is applied using the structure as shown in Fig. 2-Fig. 3, the liquid crystal display outward appearance general detection device in the present embodiment is to holding
Microscope carrier has claimed below：First, plummer needs liquid crystal display being securely fixed in surface, prevent slippage in moving process,
The problems such as rocking influence shoots picture quality；Secondly plummer needs to be provided with transparent area 210, to facilitate printing opacity to detect.At present
Mobile phone liquid crystal screen used generally includes the light transmission part 208 for display image data, and for covering front camera
Deng accessory, the lightproof part 209 around light transmission part of printing trade name.Plummer in the present embodiment utilizes negative pressure by liquid
Crystalline substance screen is fixed, therefore first through hole 206 needs all to be covered by liquid crystal display simultaneously against liquid crystal display, so as to ensure the airtight of through hole
Property.Using four first through hole 206 in the present embodiment, the immediate vicinity of liquid crystal display light transmission part 208 is evenly distributed on.
The transparent area 203 overlapped with liquid crystal display light transmission part 206 includes two pieces of glass plates, i.e. the first transmission element 202 up and down
With the second transmission element 203, it is connected in gluing on support member 201, vacuum silicon grease is smeared at gap, to ensure its air-tightness, first
Transmission element 202, the second transmission element 203 and support member 201 define cavity 205, and first through hole 206 is connected with cavity 205；Cavity
205 are also connected with the second through hole 207 and the insertion of valve 204, it is formed by the method for external vavuum pump in cavity 205
Negative pressuren zone, liquid crystal display is held using negative pressure.Fig. 5 furthermore present the installation method of plummer in the utility model, plummer
504 build between two linear electric motors 501, and printing opacity detects that the 3rd light source 502 is arranged on below the station of plummer 504, to prevent
Only linear electric motors track blocks source light, it is ensured that liquid crystal display 503 can be completely covered in the light of the 3rd light source 502.
Fig. 6 gives the structural representation of image collecting device in the present embodiment, as illustrated, the first light source 601, second
Light source 602 and camera 603 may be contained within the tested top of liquid crystal display 604, and the first light source 601 and tested liquid crystal display 604 are facing each other.
The Normal plane 609 of liquid crystal display 604 is defined by the position and direction of liquid crystal display 604, secondary light source 602 and camera 603 are distinguished
Positioned at the both sides of Normal plane 609.Wherein, the slant setting of secondary light source 602, its direction of illumination defines first straight line 607, liquid
604 present positions of crystalline substance screen are default tested position, and the first straight line 607 that the secondary light source 602 is limited is in station plane
Marked in 20 degree of angles, figure with 605.Camera 603 is equally obliquely installed, and its position and direction defines second straight line 608, and this second
Straight line 608 and station plane are marked in figure with 606 in 15 degree of angles.Further, since liquid crystal display 604 has certain length, in order to
Make the surface exposure degree of liquid crystal display 604 more uniform, the first light source 601, secondary light source 602 are used and the quilt of liquid crystal display 604
The line source that inspection face be arranged in parallel, using two-source illumination, one of them polishing scheme being obliquely installed can be respectively to liquid crystal
The cut of the transverse direction and longitudinal direction of screen targetedly polishing, so as to take into account the scuffing defect of two kinds of orthogonal directions；In addition, this
Scheme is taken pictures using details in a play not acted out on stage, but told through dialogues, can improve the picture contrast of normal region and defect area, so that algorithm is detected.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
Member just can make many modifications and variations without creative work according to design of the present utility model.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to design of the present utility model in domain
Available technical scheme is tested, all should be in the protection domain being defined in the patent claims.
