Description
Technical field
The utility model relates to a kind of for checking compact LED multi-wafer guiding device.
Background technology
At present in the time that LED is detected, we do not add the tool of any auxiliary CCD reading out data, directly read the LED optical information in the CCD camera lens visual field by CCD, in the time that the LED spread length on LED module is very near, CCD resolution cannot be carried out identification data one by one to adjacent spots, be that CCD is detecting LED process, CCD lack of resolution, when two LEDs near time, two hot spots mix, what CCD captured is two hot spots that LED mixes, a rather than single hot spot, cannot be accurately by the data separating of two LED, cause data distortion rate very high, give design in early stage, later stage produces and each management link brings erroneous judgement, therefore, need to design the resolution that a set of CCD auxiliary fixture detects to improve CCD.
Summary of the invention
While detecting LED with CCD in the purpose of this utility model solution prior art, because of CCD lack of resolution, when two LEDs near time, the hot spot of obscuring that CCD can only capture, rather than the single hot spot capturing respectively, thereby cannot accurately judge and the quality of LED performance cause the problem that data distortion rate is very high, provide a kind of for checking compact LED multi-wafer guiding device.The utility model design one is used for checking compact LED multi-wafer guiding device, comprise CCD camera lens, fiber end face stationary installation, optical fiber fixed block, it is characterized in that: have a support, formed by upper substrate, Intermediate substrate and substrate, between upper substrate and Intermediate substrate, there is connecting link to be fixedly connected with, on Intermediate substrate, be provided with connection trepanning, it is upper that adapter sleeve borehole jack is contained in the column being arranged on substrate, column has four, be positioned at four jiaos of rectangle, on the column of pair of horns wherein, cover has spring, and spring is between Intermediate substrate and substrate; Four bundle optical fiber, the output terminal of optical fiber is connected with the optical fiber fixed block being arranged on upper substrate through upper substrate, the input end of optical fiber is connected with the fiber end face stationary installation being arranged on Intermediate substrate bottom surface through Intermediate substrate, be provided with two buckles in substrate both sides, buckle is corresponding with Intermediate substrate, and LED pickup groove to be measured is installed on substrate under fiber end face stuck-module.The optical fiber end of fiber end face stuck-module is corresponding with LED pickup groove to be measured.Advantage of the present utility model: this device self positioning structure is simple, easy to operate, and locating accuracy is high.When LED closely arranges, can capture single LED hot spot, effectively improve the resolution of CCD, improve the accuracy rate that data read, improve the degree of accuracy that CCD detects.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, structure of the present utility model is described.
Figure comprises CCD camera lens 1, fiber end face stationary installation 2, optical fiber fixed block 3, it is characterized in that: have a support, formed by upper substrate 4, Intermediate substrate 5 and substrate 6, between upper substrate and Intermediate substrate, have connecting link 7 to be fixedly connected with, be provided with and connect trepanning 8 on Intermediate substrate, it is upper that adapter sleeve borehole jack is contained in the column 9 being arranged on substrate, column has four, be positioned at four jiaos of rectangle, on the column of pair of horns wherein, cover has spring 10, and spring is between Intermediate substrate and substrate; A branch of optical fiber 11, the output terminal of optical fiber is connected with the optical fiber fixed block being arranged on upper substrate through upper substrate, the input end of optical fiber is connected with the fiber end face stationary installation being arranged on Intermediate substrate bottom surface through Intermediate substrate, be provided with two buckles 12 in substrate both sides, buckle is corresponding with Intermediate substrate, and LED pickup groove 13 to be measured is installed on substrate under fiber end face stuck-module.The optical fiber end of fiber end face stuck-module is corresponding with LED pickup groove to be measured.
When work, by the utility model be fixed on CCD camera lens under, then open buckle, spring is in relaxed state, drive upper substrate and Intermediate substrate to rise, LED board to be measured is placed in the LED pickup groove to be measured of substrate, then buckle is fastened to Intermediate substrate, spring-compressed, Intermediate substrate drives fiber end face stationary installation downward, now the fiber end face of fiber end face stationary installation and LED upper surface approximate zero to be measured distance are pressed close to, switch on power, LED lights, the fiber end face of fiber end face stationary installation is transferred to LED light the optical fiber fixed block being arranged on upper substrate, then start by CCD camera lens reading out data.
After having detected this LED board, open buckle, change LED board, light and detect again.
