Abstract
The utility model relates to an auxiliary tool, and particularly relates to a device for detecting the printing dots of a light guide plate, belonging to the field of producing and processing of light guide plates. The device comprises a support, a reflective back plate and a linear light source, wherein the support is provided with at least one upright frame; the reflective back plate is vertically arranged on the upright frame; and the linear light source is transversely arranged on the upright frame and located in front of the reflective back plate. The device provided by the utility model is used for detecting the printing dots of the light guide plate.
Description
Technical field
The utility model relates to auxiliary fixture, relates in particular to light guide plate production and processing field, is used for the device that auxiliary light guide plate printing net-point detects.
Background technology
Light guide plate is generally to be applied in liquid crystal display, as an important component part in LED-backlit source.Light guide plate is the illumination of the line sources such as light emitting diode (LED), cold cathode fluorescent lamp (CCFL), fluorescent tube to be changed into a kind of structure member of illuminated by surface light source.
Light guide plate is to utilize the acryl of optical grade/PC sheet material, then is used in the acryl sheet material of optical grade or the bottom surface of PC sheet material and stamps light guiding points (or title " site ") with printing technologies such as UV half tone or laser.Light guide plate is that the light that utilizes optical grade acryl/PC sheet material to draw to send from line source is in the stop on optical grade acryl sheet material surface, when light is mapped to each light guiding points, reflected light can toward all angles diffusion, then destroy conditioned reflex and penetrate by light guide plate is positive.By various densitys, light guiding points not of uniform size, can make the light guide plate uniformly light-emitting on the exiting surface of light guide plate.
Thereby in the process of production light guide plate, wherein a procedure is exactly need to the printing net-point of light guide plate carefully be detected, and with the printing net-point that checks out light guide plate, whether the defectives such as leak source, Lian Dian is arranged.
Consult shown in Figure 1, existing light guide plate printing net-point pick-up unit is to comprise a base plate 1 ', the emission blank 2 ' that has been sticked on base plate 1 ', and be respectively equipped with baffle plate 3 ' at the dual-side up and down of base plate 1 ', baffle plate 3 ' is made for light-transmitting materials, is provided with linear light sources in baffle plate 3 '.When detecting the light guide plate printing net-point, light guide plate is placed on the emission blank 2 ' of base plate 1 ', then is placed on work top and rolls, bad to check whether printing net-point leak source, Lian Dian etc. occur.The weak point that detects by this light guide plate printing net-point pick-up unit is: be placed on to cause detecting in this pick-up unit and increase man-hour, and may be when detecting the printing net-point on emission blank 2 ' friction light guide plate and cause new defective.
The utility model content
Therefore, the utility model proposes a kind of light guide plate printing net-point pick-up unit, the edge generation of the new defective such as scratch of damaging, rub in the time of can avoiding detecting by this light guide plate printing net-point pick-up unit, and detection efficiency is higher.
The utility model adopts following technical scheme:
Light guide plate printing net-point pick-up unit comprises:
One support, this support have a upright framework at least;
One reflective back plane, this reflective back plane uprightly are arranged on the upright framework of above-mentioned support;
One linear light sources, this linear light sources laterally are arranged on the upright framework of above-mentioned support, and before being positioned at above-mentioned reflective back plane.
Further, described linear light sources is straight strip type fluorescent light (namely being commonly called as " daylight lamp ").
Perhaps, described linear light sources is straight strip type LED lamp.
Further, described reflective back plane is the black reflection backboard.
The utility model adopts as above technical scheme, can detect by hand-held light guide plate, can shorten the running time.In addition, be to detect by vertical type, can not touch reflective back plane, therefore can not appear at damage, the rub generation of the bad phenomenon such as scratch of light guide plate edge when detecting.
Description of drawings
Fig. 1 is the structural representation of existing light guide plate printing net-point pick-up unit;
Fig. 2 is the structural representation of the utility model one embodiment;
Fig. 3 is the schematic diagram that the light guide plate printing net-point detects that carries out of this embodiment.
Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
Consult shown in Figure 2ly, the light guide plate printing net-point pick-up unit of embodiment comprises:
One support 1, this support 1 have a upright framework 11 at least.
One reflective back plane 2, this reflective back plane 2 uprightly are arranged on the upright framework 11 of above-mentioned support 1; Preferably, described reflective back plane 1 is the black reflection backboard, can form the black and white sharp contrast, thereby it is better to detect effect.
One linear light sources 3, this linear light sources 3 laterally is arranged on the upright framework 11 of above-mentioned support 1, and before being positioned at above-mentioned reflective back plane 2.Preferably, described linear light sources 3 is straight strip type fluorescent light (namely being commonly called as " daylight lamp ").Perhaps, described linear light sources 3 is straight strip type LED lamp.
Consult shown in Figure 3, when utilizing this light guide plate printing net-point pick-up unit to detect the printing net-point of light guide plate 4, by held by both hands one light guide plate 4, then in linear light sources 3 front left and right of this pick-up unit, upper and lowerly slightly rock, check that the printing net-point on light guide plate 4 has or not the defectives such as leak source, Lian Dian.
To sum up, the technological merit that has of light guide plate printing net-point pick-up unit of the present utility model is:
(1), this light guide plate printing net-point pick-up unit can the suitable for multiple sizes type light guide plate, thereby save cost;
(2), when adopting this light guide plate printing net-point pick-up unit to detect, operating personnel reduce and once to take, to place action, can reduce 8 second activity duration on the time;
(3), when adopting this light guide plate printing net-point pick-up unit to detect, therefore light guide plate (LGP) is not attached to reflective back plane, can exist the light guide plate edge scratch bad phenomenon of damaging, rub to occur.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
