Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to an inclined X-ray horizontal detection device. Background Art

[0002] X-ray detection is based on the attenuation characteristics of X-rays as they penetrate matter. Materials of varying densities have varying absorption coefficients (μ) for X-rays, resulting in variations in transmission intensity and image contrast. The typical detection process involves three physical effects: the photoelectric effect, where low-energy X-rays interact with inner-shell electrons; Compton scattering, where medium-energy X-rays collide elastically with free electrons; and the electron pair effect, where high-energy X-rays interact with atomic nuclei to generate electron-positron pairs. Detectors capture the transmitted or scattered signals, producing a two-dimensional grayscale image or three-dimensional volume data of the material's internal structure.

[0003] Under existing technology, slender workpieces are transported to designated inspection positions via conveyors. When the radiation penetrates the workpiece vertically for inspection, the radiation path through the workpiece is the longest, requiring higher radiation energy or more inspection time, resulting in increased equipment costs and reduced inspection efficiency. Summary of the Invention

[0004] The object of the present invention is to provide an inclined horizontal X-ray detection device. By tilting the X-ray detection device by 15 degrees, the ray penetration path can be reduced, energy attenuation can be reduced, and image quality can be improved.

[0005] To achieve the above-mentioned object, the present invention provides a horizontal inclined X-ray detection device, comprising a detection lead room and auxiliary components; The auxiliary components include a detection frame, a radiation source, a flat-panel detector, a turntable, a high-precision slewing bearing, a servo motor, a transmission synchronous belt, a conveying member, a mounting member and a fixing member. The detection frame is removably mounted on a removable base plate in the detection lead room. The radiation source is arranged on the turntable through a connecting member. The flat-panel detector is mounted on one side of the detection frame through the mounting member. The turntable is fixedly connected to the inner ring of the high-precision slewing bearing and is 15° away from the top standard plane of the base plate. The outer ring of the high-precision slewing bearing has gear teeth and is rotatably mounted on the detection frame. The servo motor is mounted on one side of the detection frame through the fixing member. A synchronous wheel is mounted on its output shaft. The transmission synchronous belt engages with the gear teeth on the synchronous wheel and the outer ring of the high-precision slewing bearing respectively to realize transmission, and a tensioner is mounted on the detection frame through a positioning member for sliding contact. The conveying member is arranged through the hollow part of the detection frame, and the mounting member is used for mounting the flat-panel detector.

[0006] Wherein, the conveying component includes a frame and a synchronous belt conveyor, the frame is arranged on both sides of the detection frame; the synchronous belt conveyor is arranged on the frame.

[0007] Wherein, the conveying member further includes a reinforcing component, and the reinforcing component is arranged on the frame of one of the synchronous belt conveyors.

[0008] Among them, the mounting component includes a support plate, a reinforcement plate and an axial flow fan, the support plate is detachably connected to the turntable; the reinforcement plate is arranged on both sides of the bottom of the support plate; the axial flow fan is installed on the outside of the ventilation hole at the bottom of the support plate and is located below the flat panel detector.

[0009] Wherein, the fixing component includes a fixing plate and a motor mounting plate, and the fixing plate is detachably mounted on one side of the detection frame; the motor mounting plate is detachably connected to the servo motor and the fixing plate respectively.

[0010] Wherein, the positioning component includes a mounting shaft and a rolling bearing. The mounting shaft is fixedly connected to the detection frame and is close to the transmission synchronous belt. The rolling bearing is sleeved on the mounting shaft and installed in the mounting inner cavity of the tensioner.

[0011] The connecting component includes a ray tube mounting seat and a triangular plate. The ray tube mounting seat is detachably connected to the rotary disk and is equipped with the ray source. The triangular plate is symmetrically welded to the bottom of the ray tube mounting seat.

[0012] The present invention discloses an inclined horizontal X-ray inspection device that transports a workpiece via a conveying member. When the workpiece reaches a designated position, the X-ray source is activated. When the X-ray source and the flat-panel detector reach a designated angle (the origin position is 0°), a PLC issues a command, and the flat-panel detector begins capturing images while rotating. The servo motor operates, driving the synchronous wheel. The drive belt enables high-precision rotation of the slewing bearing, allowing the X-ray source and flat-panel detector to rotate 360° around the workpiece to capture images. The flat-panel detector captures images at a rate of 30 images per frame, precisely matching the captured images with the circular rotational motion to ensure a consistent number of images captured at each angle. Upon completion, the conveying member transports the workpiece forward, crossing the intermediate gap to reach another conveying member. Workpieces outside the inspection chamber also enter the inspection position via the conveying member. By tilting the X-ray inspection device by 15°, the X-ray penetration path can be reduced, energy attenuation can be reduced, and image quality can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the present application will be able to reduce the ray penetration path, reduce energy attenuation, and improve image quality by tilting the X-ray detection device by 15°.
