Abstract
The utility model discloses a kind of devices for realizing the range estimation of light guide plate mesh point position, including printing plate body, the printing plate body dimension is consistent with guide-lighting board size, its central area has net-point printing hole, and four angles of printing plate are respectively provided with marking line, which is printing the both sides of plate angle, is net-point printing tolerance value with lateral edges distance, during net-point printing, marking line is printed on light guide plate simultaneously with site.
Description
Technical field
The utility model is related to a kind of light guide plate more particularly to a kind of devices for realizing the range estimation of light guide plate mesh point position.
Background technology
The principle of light guide plate is to destroy the complete of LED light source light using site (ink site, hot pressing site are molded site)
Reflection so as to which light be allowed to be come out from light guide plate, realizes that LED line light source becomes the purpose of area source, light emitting source is provided for display.
The site of general light guide plate is to be imprinted on light guide plate surface by mode of printing, and the judgement for printing position is typically to pass through measurement
Instrument carries out dimensional measurement judgement, it usually needs the measurement on two sides is carried out, so one piece of light guide plate time of measuring is long.
More and more wider with the scope of application of backlight module, the production capacity of light guide plate is more and more, the consumption of this manual measurement
When cause capacity efficiency low, so a kind of quickly measurement form is needed to realize quick measurement.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of range estimation of realization light guide plate mesh point position
Device, when net-point printing is carried out on light guide plate printing marking line, by eye-observation realize to dot location
Quick and precisely judge.
To achieve the above object, the utility model proposes following technical solutions：A kind of range estimation of realization light guide plate mesh point position
Device, including printing plate body, the printing plate body dimension is consistent with guide-lighting board size, and central area has net-point printing
Hole, and four angles of printing plate are respectively provided with marking line, which is printing the both sides of plate angle, is with lateral edges distance
Net-point printing tolerance value, during net-point printing, marking line is printed on light guide plate simultaneously with site.
Preferably, the marking line is multiple circular holes linearly arranged, aperture is 0.01~1mm.
Compared with prior art, the revealed a kind of device for realizing the range estimation of light guide plate mesh point position of the utility model, tool
It has the advantages that：Printing marking line can be realized on light guide plate by the device, and control marking line and edge away from
From, judge whether dot area position is qualified by the deletion condition for observing marking line, it can be real without additional survey tool
Now fast and accurately judge, so as to improve the production capacity of light guide plate, increase the recall rate of bad products.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model embodiment is carried out clear, complete
Description.
As shown in Figure 1, a kind of revealed device for realizing the range estimation of light guide plate mesh point position of the utility model, including printing
Plate body 1, the printing plate body dimension is consistent with guide-lighting board size, and central area has net-point printing hole 2, in net-point printing
When, position just corresponds on light guide plate and requires, and has stamp line 3 on four angles of printing plate body, which is distributed in angle
Two vertical edges, and be net-point printing tolerance value with the Edge Distances of vertical edges, when carrying out net-point printing, stamp line
It can be printed on simultaneously on light guide plate, if net-point printing position is correct, the marking line on that four angles is appeared on light guide plate,
Once there have any one marking line to occur on four angles to be incomplete or invisible, illustrating that the dot location has exceeded allows model
It encloses, which can be multiple circular holes linearly arranged, and 0.01~1mm is in aperture or linearly arranges
Other shapes, be mainly distributed on two sides at angle, with Edge Distance be site tolerance value.
The technology contents and technical characteristic of the utility model have revealed that as above, however those skilled in the art still may be used
Teaching and announcement that can be based on the utility model and make a variety of replacements and modification without departing substantially from the utility model spirit, therefore, this
Utility model protection scope should be not limited to the revealed content of embodiment, and should include the various replacements without departing substantially from the utility model
And modification, and covered by present patent application claim.
Claims (2)
1. a kind of device for realizing the range estimation of light guide plate mesh point position, which is characterized in that including printing plate body, the printing plate body
