Provide specifying of the utility model embodiment below.
For the small size screen, usually the panel on the whole glass substrate is divided into several panel areas, as shown in Figure 3, on glass substrate 5,64 panels are divided into 8 panel areas; Be respectively Q1, Q2, Q3; Q4, Q5, Q6; Q7 and Q8 beat identical panel sign for each panel of each panel area the inside, and the sign of the panel in the different panel areas are different; For example: for the 1AAZD80001AA that is designated of first panel inside the Q1, remaining seven panel also is 1AAZD80001AA, and is 1AAZD80001AB for eight panels signs of Q2 the inside.
It is thus clear that; The panel sign of each panel area the inside is identical, therefore can pass through to use a light source, and generate corresponding identification image in this light source front; The image that will be loaded with panel sign through different prisms then is divided into several bundles to be beaten on glass substrate, generates identical panel and identifies.
Simultaneously, in order to distinguish the panel in the different panels district, last position of the panel sign in the panel area that can be different is set to different identification; Therefore consider two or the mark simultaneously of more a plurality of panel area; As shown in Figure 4, the vertical view of the two-way panel area mark machine light path system that comprises single light source and prism group that provides for the utility model embodiment, being used for is the panel mark in two different panels districts simultaneously; Wherein, can be four panel marks in each panel area simultaneously.
Particularly, generate sign, for example 1AAZD80001A in the front in lamp source 1; Emergent light is divided into two bundles through prism 7 then; A branch of transmission, another bundle reflexes to prism 13, is pasted with reflectivity on the surface of prism 13 and is 100% the anti-film that passes through; And be pasted with reflectivity on the surface of prism 7 is 50% the anti-film that passes through, and can guarantee that the light intensity of two-way light equates.That is to say that prism 7 is equivalent to the branching unit 102 shown in Fig. 2 with prism 13.
Light for from prism 7 transmissions produces identical panel sign through prism 9,10,11 and 12; And produce identical panel sign through prism 9,10,11,12 for light from prism 13 reflections, that is to say that prism 9,10,11 and 12 is equivalent to the many groups mark unit 103 shown in Fig. 2; Be used to two panel marks in the panel area; Perhaps, also can be the panel mark in the same panel area, for example; Can be two row panel marks among the Q1 simultaneously, identify identical; Perhaps, also can be the first row panel and the first row panel mark among the Q2 among the Q1 simultaneously, through sign dish 8, make the sign of the first row panel among the Q1, different with the sign of the first row panel among the Q2; 6 for carrying dressing table among Fig. 4, is used to carry prism 9,10,11 and 12.
That is to say,, add a sign dish 8 respectively, be used to produce the distinctive marks such as last or two of panel sign in prism 7 and 13 back for the two-way light that makes prism 7 and prism 13 penetrate produces different panel signs.These two sign dishes 8 are equivalent to the tag slot subdivision 104 shown in Fig. 2.
For example, the sign dish 8 of prism 7 back is used for producing sign A, and the sign dish 8 of prism 13 back is used for producing sign B, and the panel sign in then corresponding two different panels districts is respectively 1AAZD80001AA and 1AAZD80001AB.Perhaps, the sign dish 8 of prism 7 back is used for producing sign AB, and the sign dish 8 of prism 13 back is used for producing sign CD, and the panel sign in then corresponding two different panels districts is respectively 1AAZD80001AAB and 1AAZD80001ACD.
For each road light, be example with prism 7 light path at the back.Adopt drift angle to be the prism of 90 degree, as shown in Figure 5, a branch of light of single light source 1 emission; After prism 7 and sign dish 8; Incident light is got on the prism 9, and a part reflexes to and forms the panel identification image on the glass substrate, and another part projects on the prism 10; By that analogy, to be respectively applied for be a panel mark to prism 9,10,11 and 12.
Referring to Fig. 6; For the intensity of reflected light that guarantees four prisms 9,10,11 and 12 basic identical; Corresponding stick one deck at each prism surface and pass through anti-film 14, corresponding reflectivity is: the reflectivity that pass through anti-film on prism 9 surfaces are about 25%, and the reflectivity that pass through anti-film on prism 10 surfaces are about 33%; The reflectivity that passes through anti-film on prism 11 surfaces is about 50%, and the reflectivity that passes through anti-film on prism 12 surfaces is 100%.Like this, can be divided into the essentially identical four bundle light of four bundle illumination through the light that this light path is sent a light source.
Fig. 7 and front and the side view that is respectively sign dish 8 shown in Figure 8; Last bit-identify that needs generation; By computer program control motor starting, thereby make sign disc spins certain angle, thereby throw different last bit-identifies to corresponding panel to corresponding letter or number.
Wherein, sign dish 8 shown in Figure 7 is used for generating simultaneously a bit-identify, also can change other sign dishes into, generates the multidigit sign simultaneously.
The device shown in Figure 4 that the utility model is given an example is to be the device of two different panels districts mark simultaneously, certainly, can according to actual needs the prism of more groups be set, to be embodied as the device of more a plurality of different panels district mark simultaneously.
In sum, traditional mark mode, for the small size panel, the mark time significantly increases, if increase light source and camera lens number, causes replacing and maintenance cost bigger.And the utility model is through using single light source and adding that multichannel prism group realizes the light path scheme of multichannel mark; Can utilize the mark processing procedure of TFT LCD; Reduce the quantity in lamp source and the number of lens image display driver, significantly reduce the replacing and the maintenance cost in lamp source, and can realize the mark simultaneously of a plurality of panel areas; Promote mark efficient, increase production capacity.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
