Technical Field

[0001] The utility model belongs to the technical field of automation equipment, and in particular relates to an imaging detection device with CT and DR dual functions. Background Art

[0002] DR detection technology is a real-time X-ray digital imaging technology with strong real-time performance. It can perform non-destructive detection of quality defects such as structural medium discontinuity, structural morphology, and medium physical density of production products in real time. Industrial CT detection technology uses X-rays to detect products without damaging them. In the form of two-dimensional tomographic images or three-dimensional stereo images, it can clearly, accurately, and intuitively judge and measure the physical and chemical properties of the product to be detected, such as structure, density, characteristic size, and composition changes.

[0003] The radiation source devices of conventional DR detection equipment or CT detection equipment are generally fixed in a certain position, which makes it impossible to shoot a large range of the product to be tested or to shoot a certain part of the product separately. It is not easy to operate and cannot meet the cross-scale measurement requirements and different resolution requirements of large and small samples. Utility Model Content

[0004] The purpose of the utility model is to provide an imaging detection device with dual functions of CT and DR, which can realize the ability to shoot a wide range of products to be detected, to shoot a certain position of the product separately, and to shoot products of different sizes by adjusting the position of the ray source device.

[0005] An imaging detection device with dual functions of CT and DR includes a base, on which is installed a longitudinal screw rod module of a radiation source, which drives a longitudinal movement frame of the radiation source, on which is installed a radiation source lifting screw rod module, which drives a radiation source mounting platform, on which is detachably mounted a radiation source device for emitting X-rays, a detection mounting platform and a product clamp are provided on the base, on which is detachably mounted a detector cooperating with the radiation source device, and the product clamp is located between the radiation source mounting platform and the detector.

[0006] According to the technical solution, the utility model can achieve the following beneficial effects:

This imaging detection equipment drives the longitudinal movement of the radiation source longitudinal moving frame through the radiation source longitudinal screw module, and drives the radiation source installation platform to move up and down through the radiation source lifting screw module, so as to drive the radiation source device installed on the radiation source installation platform to move. Therefore, under the condition of occupying the same space, the radiation source device realizes multi-axis linkage through the radiation source longitudinal screw module and the radiation source lifting screw module, so that a wide range of products to be inspected can be photographed, a certain position of the product can be photographed separately, and products of different sizes can be photographed;

[0008] 2.

[0009] 3. Since this imaging detection equipment uses a radiation source device to emit a collimated radiation beam with a certain energy to pass through the inspected product, the projection energy received by the detector is different according to the different attenuation coefficients of each volume element in each transmission direction. After a series of signal conversions, a scanned image is obtained; in DR scanning, CCD imaging is used, and X-rays are directly used for imaging processing to obtain an overlapping image of the object passed by the X-rays in the irradiation direction; therefore, the imaging detection equipment has both DR and CT functions.

Therefore, the imaging detection device can be used in DR scanning and CT scanning.

[0042] The following is an instruction for use of the imaging detection device described in this specific embodiment:

[0043] The imaging detection device drives the longitudinal movement of the radiation source frame 21 through the longitudinal screw module 2 of the radiation source, and drives the radiation source mounting platform 23 to move up and down through the radiation source lifting screw module 22, so as to drive the radiation source device 27 installed on the radiation source mounting platform 23 to move; the transverse screw module 11 drives the detection transverse movement frame 3 to move laterally, and the detection transverse movement frame 3 drives the detection mounting platform 34 to move laterally, so as to adjust the distance between the detector 36 installed on the detection mounting platform 34 and the product clamp 46 or\ and the radiation source device 27; the detection lifting screw module 31 drives the detection lifting frame 32 is lifted and lowered, and the detection lifting frame 32 drives the detection mounting platform 34 to lift and lower, so that the detection mounting platform 34 can be lifted and lowered horizontally synchronously with the ray source mounting platform 23, thereby avoiding the occurrence of smear during shooting, and at the same time, the height of the detector 36 can be realized according to the product size; when adjusting the longitudinal position of the ray source device, the detection mounting platform 34 can be driven to move longitudinally through the detection longitudinal screw rod module 33, so that the detection mounting platform 34 can be moved synchronously with the ray source mounting platform 23, thereby avoiding the occurrence of smear during shooting, and at the same time, the longitudinal position of the detector 36 can be realized according to the product size;

[0044] The product transverse moving frame 4 can be driven to move by the transverse moving screw module 11, and the product transverse moving frame 4 drives the product clamping claw 46 to move transversely, so as to adjust the distance between the product clamping claw 46 and the detector 36 or the radiation source device 27; the product longitudinal moving frame 42 can be driven to move by the product longitudinal moving screw module 41, and the product longitudinal moving frame 42 drives the product clamping claw 46 to move longitudinally; the product clamping claw 46 can be driven to rotate 360 ​​degrees by the rotating motor 45, so as to realize shooting of multiple positions and multiple angles of the product;

[0045] Therefore, the radiation source device 27 realizes multi-axis linkage through the radiation source longitudinal screw module 2 and the radiation source lifting screw module 22, the detector 36 realizes multi-axis linkage through the transverse screw module 11, the detection lifting screw module 31 and the detection longitudinal screw module 33, and the product clamped by the product clamp 46 realizes multi-axis linkage and 360-degree rotation through the transverse screw module 11, the product longitudinal screw module 41, the product lifting screw module 43 and the rotating motor 45, so that while occupying the same space, a large range of products to be inspected can be photographed, a certain position of the product can be photographed separately, and products of different sizes can be photographed.

[0046] Since the radiation source device 27 is detachably mounted on the radiation source mounting platform 23, and since the detector 36 is detachably mounted on the detection mounting platform 34, it is possible to replace radiation source devices 27 and detectors 36 of various brands and models according to the needs of detecting different products, so as to improve compatibility and meet different resolution requirements.

[0047] Since the imaging detection equipment utilizes a collimated radiation beam with a certain energy emitted by a radiation source device 27 to pass through the inspected product, the projection energy received by the detector 36 is different according to the different attenuation coefficients of each volume element in each transmission direction. After a series of signal conversions, a scanned image is obtained. In DR scanning, CCD imaging is used, and X-rays are directly used for imaging processing to obtain an overlapping image of the object passed by the X-rays in the irradiation direction. Therefore, the imaging detection equipment can be used in DR scanning and CT scanning.
