Abstract

A TFT-LCD liquid crystal glass substrate warp detection device comprises a box body, a white board provided with black grids and arranged in the box body, and an illumination light source; wherein a trolley for housing glass is arranged in front of the box body. By adopting the technical proposal of the utility model, the illumination light is directly combined with the white board and transformed into a light box, the form of the white board with the black grids is not changed, the illumination light is changed into 16 60W light tubes and the light tubes are arranged in the light box, the transformed light box is very light and uniform, the heat generated by the light tubes is obviously reduced, more power is saved, the power consumption before transformation is 4500W/H and the power consumption after transformation is 960W/H, so as to satisfy the normal production requirement.

Description

TFT-LCD liquid crystal glass base warpage pick-up unit

Technical field

The utility model relates to a kind of pick-up unit required when adopting the outward appearance detection method to judge liquid crystal glass base.

Background technology

Current, the warpage of liquid crystal glass base detects has dual mode usually, and a kind of is the outward appearance detection method, and another kind is the instrument detecting method.The advantage of outward appearance detection method has: detection architecture is simple, cheap, detection speed soon, very directly perceived, come into plain view; Shortcoming is: testing result does not have to datumize, accuracy of detection is not enough, need be familiar with warpage judges the limit sample, need in the darkroom of 5-7 rice, detect.The advantage of instrument measuring method is: the whole digitizings of testing result, accuracy of detection height, testing result accurately, do not need warpage limit sample, need only and set the warpage specification; Shortcoming is: checkout equipment is complicated, apparatus expensive (at present need from external import), Measuring Time are long, data need be passed through to handle and made three-dimensional picture and just make things convenient for technology adjustment countermeasure.

Outward appearance detects ratio juris: as shown in Figure 1; The blank 3 of searchlight 4 irradiation band black grids is put a glass 1 on the dolly 2 in blank 3 the place aheads, a black cloth is put in the glass below; Under the environment in darkroom, working as mirror to glass uses; Judge through the degreeof tortuosity of mesh lines on the reflection sight glass of light whether warpage is qualified, the big more explanation warpage of mesh lines on glass distortion is big more, and mesh lines on glass twists that the bright warpage of novel is more little more.Known outward appearance checkout equipment has following ingredient: the blank 3 of a band black grid, breadth is 2m*2.5m, the searchlight 4 of three 1500W, the removable liftable glass dolly 2 of putting.Because of searchlight is positioned over a side of blank, the dark phenomenon in bright one side on one side appears in observation effect, and bright zone also is local bright; Cause lamplight brightness inhomogeneous; Judgement to warpage causes certain interference, and the heat that the 1500W searchlight produces is very big, causes the darkroom temperature obviously higher.

Summary of the invention

The purpose of the utility model provide a kind of lamplight brightness evenly, produce heat few, be convenient to the pick-up unit that warpage is judged.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

The utility model comprises casing, is provided with the blank and the searchlighting light source of black grid in the casing; The place ahead at casing is provided with the dolly of putting glass.

Described searchlighting light source is the fluorescent tube of 16 60W.

Adopt the utility model of technique scheme, directly just searchlight and blank are combined, and are transformed into a lamp box; The blank form of black grid is constant, and the fluorescent tube that searchlight is made into 16 60W is put into lamp box, and it is very bright, very even to transform the back lamp box; The heat that fluorescent tube produces obviously reduces, and more power saving, and power consumption is 4500W/H before transforming; Transforming back power consumption is 960W/H, and can satisfy the ordinary production needs.

Description of drawings

Fig. 1 is the structural drawing of outward appearance checkout equipment in the prior art.

Fig. 2 is the one-piece construction synoptic diagram of the utility model.

Embodiment

As shown in Figure 2, the utility model comprises casing 5, is provided with the blank 3 and searchlighting light source of black grid in the casing 5; The place ahead at casing 5 is provided with the dolly 2 of putting glass.

Above-mentioned searchlighting light source is the fluorescent tube of 16 60W, and it is very bright, very even to transform the back lamp box, and result of use is fine, installs more convenient.
