From the above mentioned, flaky material perspective pick-up unit of the present invention, that luminophor 2 is set on cylinder 1 surface, outside cylinder, (outside) is correspondingly set to the illuminating source 4 that luminophor provides energy simultaneously, when ensureing that luminophor 2 rotates to the position of optical measuring element 3 with cylinder 1, there is the luminous intensity met needed for imaging, the clear fluoroscopy images in the region to be checked in flaky material 9 can be obtained thus, owing to have employed cylinder transmission mode, the fluoroscopy images of better quality and the measuring accuracy of Geng Gao can be obtained; Meanwhile, because the cylinder in the present invention does not adopt the mode of being powered to drums inside luminophor by wire or slip ring, therefore, roller frame can simplify greatly, make cylinder be easy to manufacture, be convenient to safeguard, be in operation and not easily break down, reduce operation and maintenance cost.
Embodiment one
As shown in Figure 1, in the present embodiment, described luminophor 2 is made up of luminescent material 21, and described luminescent material 21 is long-afterglow material; This long-afterglow material, after illumination, can keep the fluorescent lifetime grown very much and luminous intensity.Particularly, described long-afterglow material can be sulfide or rare earth compound etc.In the present embodiment, be that this luminescent material described is sprayed on the outer cylinder surface of cylinder 1.Described luminescent material 21 can be sprayed on the whole outer cylinder surface of cylinder, also can be sprayed at part surface.Illuminating source 4 provides energy to described long-afterglow material, ensures that long-afterglow material has to during optical measuring element 3 position the luminous intensity met needed for imaging with drum rotating.In the present embodiment, described optical measuring element 3 can be the devices such as camera; Described illuminating source 4 can be electric light source (such as: Halogen lamp LED), and described electric light source can luminous intensity as required arrange multiple, and is controlled to open by a control system 7.
When the cylinder surface being coated with long-afterglow material rotates the position to the illuminating source 4 of downside, electric light source irradiates described long-afterglow material (the unlatching quantity of described electric light source and intensity of illumination can adjust according to factors such as cylinder velocities of rotation), when the cylinder surface that this is coated with long-afterglow material rotates the camera position to upside, its continuous illumination, the clear picture in the region to be checked in flaky material 9 can be had an X-rayed, to make camera obtain fluoroscopy images clearly, the data obtained are passed to control system 7 by camera.
In the present embodiment, in the position of adjacent optical measuring sensor 3 and corresponding flaky material transfer path 11 is provided with illuminance transducer 5; This illuminance transducer 5 is used for measuring the luminous intensity of luminescent material 21 when optical measuring element 3.Measurement result can be passed to control system 7 by this illuminance transducer 5, and control system 7 can carry out Real-Time Monitoring according to this measurement result to the luminous intensity of luminescent material 21, to provide information warning; Control system can control according to the luminous intensity of this measurement result to illuminating source 4, has reached when luminescent material 21 runs to camera position and sufficient luminous energy still can be provided to complete imaging.
Further, in the present embodiment, a kind of mode of improvement can also be adopted, first luminescent material 21 is sprayed in a flexible parent metal (not shown), more described flexible parent metal is fixed on the outer cylinder surface of cylinder 1; Described flexible parent metal outside surface can be provided with protective clear layer, and this protective seam can prevent luminescent material from coming off.This protective seam has smooth outside surface, is conducive to obtaining better having an X-rayed measurement data.
From the above mentioned, shape material perspective pick-up unit of the present invention, makes flaky material stable in cylinder surface transmission, can obtain better flaky material perspective and detect data, thus can improve measuring accuracy further; Meanwhile, because the cylinder in the present invention does not adopt the mode of being powered to drums inside luminophor by wire or slip ring, therefore, roller frame can simplify greatly, make cylinder be easy to manufacture, be convenient to safeguard, be in operation and not easily break down, reduce operation and maintenance cost.
Embodiment two
The present embodiment is substantially identical with structure with the principle of embodiment one, and its difference is, as shown in Figure 2, luminophor 2 described in the present embodiment is by light-emitting device 22(electric light source) form, this light-emitting device 22 is fixed on the outer cylinder surface of cylinder 1; Be positioned at the opposite side cylinder outer cylinder surface relative with light-emitting device 22 and be provided with photo-electric conversion element 6; Described light-emitting device 22 is electrically connected with photo-electric conversion element 6.
In the present embodiment, the upper surface of described light-emitting device 22 and photo-electric conversion element 6 higher than cylinder external cylindrical surface, to enable outer surface of cylinder form smooth, complete arc surface, should not can not interfere the transmission of flaky material.
In the present embodiment, described light-emitting device 22 and photo-electric conversion element 6 correspondence can arrange many groups.Described light-emitting device 22 is LED; Described photo-electric conversion element 6 is photoelectric cell or photodiode.Each light-emitting device 22 can be electrically connected with one or more photo-electric conversion element.
When photo-electric conversion element 6 rotates the position to the illuminating source 4 of downside with cylinder surface, illuminating source 4 irradiates photo-electric conversion element 6, photo-electric conversion element 6 produces electric energy and passes to light-emitting device 22 and make it luminous, now, light-emitting device 22 is arranged in flaky material transfer path 11 on the upside of cylinder and corresponding with camera just, the clear picture in the region to be checked in flaky material 9 can be had an X-rayed, to make camera obtain fluoroscopy images clearly, the data obtained are passed to control system 7 by camera.
Should ensure when cylinder surface fixes light-emitting device 22 and coupled photo-electric conversion element 6, when light-emitting device 22 runs to image space, coupled photo-electric conversion element 6 should move within the light area of illuminating source 4, and ensures that the luminous intensity of light-emitting device 22 can meet the needs intensity that image camera obtains flaky material perspective imaging.
