Summary of the invention
Have problems in order to solve in the above-mentioned prior art, the purpose of this utility model provides a kind of two array solid probe modules that are used for radiant image, and it is the further improvement on No. 200420009317.3 patented technology bases.Under the prerequisite that does not reduce existing check system spatial discrimination, improve inspection speed greatly, and strengthen the ability of opposing ray scattering on the line face and size fully can with single array solid probe compatibility, the convenient inspection speed that promotes radiation image-forming system.
In order to reach above-mentioned goal of the invention, the technical solution of the utility model realizes as follows:
The double-array detector modular structure that is used for radiant image, it comprises housing, base plate and the solid detector array of being made up of a plurality of solid probes.Housing bottom and base plate are fixed.Place solid detector array on the below of housing, the base plate, the front end edge of solid detector array is along the collimating apparatus that has been equipped with collimation and anti-scattering process.Housing is built-in with support wiring board is fixed.The last front end face of housing is equipped with each socket that is connected with wiring board.The upper end of housing is fitted with the upper cover plate with its form fit.Its design feature is, described solid detector array is made up of double solid detector array up and down, last row solid detector array be fixed on the PCB upper supporting plate that is connected with the back prop upper end with the collimating apparatus upper surface below, the following solid detector array of arranging is fixed on the collimating apparatus lower surface with above the PCB lower carrier plate of front standing pillar, the support and connection of back prop lower end.Front standing pillar, back prop and base plate are fixed, and back prop is positioned at the lower front end face of housing.
According to above-mentioned technical scheme, described collimating apparatus is made up of last frid, multi-disc dividing plate, following frid.Each sheet dividing plate is flush-mounted in down between frid and the last frid, and is consistent with the quantity of double fixed detector up and down by each sheet shelf-shaped quantity at interval.
According to above-mentioned technical scheme, described upper cover plate is by the upper end sealing of trip bolt with itself and housing.
According to above-mentioned technical scheme, the rear end face of described housing is equipped with the bonnet of being convenient to part loading and unloading in the shell.
According to above-mentioned technical scheme, be equipped with the lead of shielding action between described inner walls and the support bearing.
The utility model in use can extremely be convenient to the installation and removal of wiring board in the housing owing to adopted said structure, is convenient to being connected of detector panel and front-end circuit plate, the fixing of base plate and shell.Importantly, adopt two array solid probes, can on the basis that does not reduce spatial resolution, improve the inspection speed of radiation imaging check system greatly.In addition,, can select the collimating apparatus of different length material for use, not only reduce the irradiation damage of photodiode, and reduce along the line face with perpendicular to the various scatterings of line face for the ray of different-energy because the detector front end edge is provided with collimating apparatus.Because the front-end circuit plate is not installed on the line face of ray, therefore also reduced the irradiation of ray front-end circuit, the serviceable life of having improved detector module again.The utility model compared with prior art, not only increased substantially inspection speed, reduced along the line face with perpendicular to the various scatterings of line face, improved the anti-scattering property of detector module, help improving the sharpness of image, and for sigmatron with not establish the application of radiation imaging check system of back collimating apparatus very favourable.
