Abstract
A kind of section-type LCD product looks into scarce device, looks into projection monitor station, optics convex lens, film rack to be checked, detection light source that scarce device includes being sequentially connected；The projection monitor station is provided with support bar, sliding block is provided with the middle part of the post upper connecting detection light source, the support bar, sliding block is connected for film to be checked placement on film rack to be checked, described film rack to be checked, and described projection monitor station is provided with lighting circuit.Described detection light source contains red, blueness, the LED lamp of green.The focal length of described convex lens is in 15cm between 30cm.The scarce device of looking into of this section-type LCD product uses the structure that a film rack to be checked, lens and light source are set on monitor station, the shadow of display pen section that need to be detected is projected out on monitor station, for testing staff with reference to contrast, as long as the device that display pen section missing can visually judge, it can make the principle that mirror image is reversed using 2 times of focal lengths of lens, the floor space of equipment is effectively reduced, with easy to use, the few advantage of detection process error rate.
Description
Technical field：
The quality inspection equipment that the utility model belongs in LCD liquid crystal display screen curtain manufacture field, and in particular to be one
That plants a section-type LCD product looks into scarce device.
Background technology：
Existing section-type LCD LCDs is low with its manufacturing cost, and display effect is various, and dynamic can be achieved and adopts
Without backlight color, more and more important effect is played in various status display occasions, and the production of this kind of product fails
Rate be exactly mainly show pen section missing, and in process of production using by product be powered light, with the naked eye carry out defects detection be
Main detection means, but for the pen section product of complicated, irregular display, human eye often loses when judging
By mistake, allow faulty goods to flow out, have impact on product quality.
The content of the invention：
The defect existed for prior art, the purpose of this utility model, which is to provide, a kind of can overcome the pen of drawbacks described above
Section-type LCD product looks into scarce device.
The technical scheme in the invention for solving the technical problem is：A kind of section-type LCD product looks into scarce dress
Put, key be it is described look into projection monitor station 4, optics convex lens 3, film rack 2 to be checked that scarce device includes being sequentially connected,
Detect light source 1；The projection monitor station is provided with support bar, the post upper connecting detection light source, the support bar
Portion is provided with sliding block, and sliding block is connected for film to be checked placement on film rack to be checked, described film rack to be checked, described
Projection monitor station be provided with lighting circuit.
Described detection light source contains red, blueness, the LED lamp of green.
The focal length of described convex lens is in 15cm between 30cm.
The film rack to be checked is arranged on 2 times of focal length points on the optical axis of convex lens, described projection monitor station with
The distance of optics convex lens is 2 times of focal lengths of convex lens.
The scarce device of looking into of of the present utility model section-type LCD product uses the film to be checked of setting one on monitor station to place
The structure of frame, lens and light source, is projected out the shadow of display pen section that need to be detected, for testing staff with reference to right on monitor station
Than as long as the device that display pen section missing can visually judge, can make the principle that mirror image is reversed using 2 times of focal lengths of lens, have
Effect reduces the floor space of equipment, with easy to use, the few advantage of detection process error rate.
Brief description of the drawings：
Fig. 1 is the utility model structural representation.
Embodiment：
As shown in figure 1, a kind of section-type LCD product looks into scarce device, it is described to look into the projection that scarce device includes being sequentially connected
Monitor station 4, optics convex lens 3, film rack 2 to be checked, detection light source 1；The projection monitor station is provided with support bar, described
Sliding block is provided with the middle part of post upper connecting detection light source, the support bar, sliding block connects film rack to be checked, and described treats
Examine for film to be checked placement on film rack, described projection monitor station is provided with lighting circuit.In use, needing to treat
Inspection film rotation 180 degree is placed on film rack to be checked, by the light of light source, into upright real image in convex lens opposite side
Near 2 times of focal lengths, that is, it is imaged on projection monitor station, the section-type LCD product that need to be detected is placed on projection monitor station, and even
Contact brightening circuit.
Described detection light source contains red, blueness, the LED lamp of green, and the wick of polychrome can send a variety of colors, match somebody with somebody
The section-type LCD product for closing different display colors is projected out distinguishing projection, to facilitate testing staff effectively to recognize product
Display defect.
The focal length of described convex lens is in 15cm between 30cm.The convex lens of 15cm to focal length between 30cm can pass through 2
The projector distance of times focal length makes image stand upside down imaging.
The film rack to be checked is arranged on 2 times of focal length points on the optical axis of convex lens, described projection monitor station with
The distance of optics convex lens is 2 times of focal lengths of convex lens.
The utility model has the advantage of by convex lens to correspondence LCD product display patterns the film carry out optics into
Picture, and operation employee is more intuitively judged into real image and LCD products display pattern overlapping contrast itself by institute
It is aobvious whether LCD products lack, and improves electrical measurement efficiency and ensures product quality.
