To achieve the above object, the technical scheme is that：A kind of defect inspection method of filter core, including following step
Suddenly：Progressively irradiation after filter core left and right ends are closed using some light sources to filter core progress from inside to outside or from outside to inside, leads to
Cross and light sensor all the time with light source opposition is set in filter core another side, light sensor receives light transmission capacity and is transformed into voltage letter
Number through signal processor amplification with being compared and being drawn on host computer characteristic pattern；When judging that it is pre- that voltage signal fluctuation amplitude is not met
When phase requires, stop the relative motion of light source and filter core, the unqualified region for making light source fix on irradiation filter core is entered to the region
Behind line flag, the centralized detecting region, the relative motion of light source and filter core is decided to continue with until detection finishes or directly terminated inspection
Survey.
Further, also comprise the steps：When detecting the unqualified region of filter core, with video camera to the region
Taken pictures in interior outside.

Table top is provided with the lower cover being provided with locating piece, locating piece for closing filter core bottom；Directly over the rotary elevating platform
Be provided with frame and put spool, put and be cased with spool for closing the upper lid of filter core upper end, and put spool bottom be provided with it is some
Light sensor, and upper lid is spacing by light sensor, the light sensor by put spool wiring and signal processor with
And host computer is electrically connected；Some lamp sources are additionally provided with the frame, the lamp source opposes with light sensor respectively.
In order to suitable for various sizes of filter core, be provided with some horizontal extension platforms, the lamp source difference in the frame
It is installed on horizontal extension platform.
To realize Automated condtrol, switch and the host computer of the lamp source are electrically connected.
Further, for the ease of detecting unqualified region, the lamp source and light sensor installation place are mounted on taking the photograph
Camera, video camera is electrically connected with host computer.
Beneficial effects of the present invention：A kind of new filter core quality determining method is provided, according to the change of light transmission capacity, Ke Yijian
The defects such as crackle and perforation, thin-walled (or even heavy wall) on filter core are measured, it is accurate and rapid；It can be grasped in comfortable environment
Make；Checking process need not contact filter core.
Brief description of the drawings
Fig. 1 is structure of the detecting device schematic diagram of the invention.
Embodiment
As shown in figure 1, a kind of defect inspection method of filter core, comprises the following steps：Profit after filter core left and right ends are closed
Progressively irradiation from inside to outside or from outside to inside is carried out to filter core with some light sources, by filter core another side set all the time with light
The light sensor of source opposition, light sensor receives light transmission capacity and is transformed into voltage signal through signal processor amplification with being compared simultaneously
Characteristic pattern is drawn on host computer；When judging that voltage signal fluctuation amplitude does not meet expected require, stop light source and filter core
Relative motion, the unqualified region for making light source fix on irradiation filter core, the region is marked, behind the centralized detecting region,
The relative motion of light source and filter core is decided to continue with until detection is finished or direct detection of end；When the unqualified area for detecting filter core
During domain, the interior outside in the region is taken pictures with video camera.
A kind of defect detecting device of filter core, wraps up and rotary elevating platform 2, rotation and lifting is provided with frame 1, the frame 1
The table top of platform 2 is provided with the lower cover 3 being provided with locating piece, locating piece for closing the bottom of filter core 12；The rotary elevating platform 2
