Description

Technical Field

[0001] This utility model relates to an X-ray non-destructive testing system, specifically a vertical assembly line automatic CT imaging testing device for inspecting various workpieces. Background Technology

[0002] The application of non-destructive testing (NDT) technology is becoming increasingly widespread, with more and more industries demanding higher precision, especially in the military and aerospace sectors. These industries require the inspection of a wide variety of workpieces with complex shapes and varying sizes. Existing traditional X-ray digital imaging equipment remains in a manual or semi-automatic inspection state, resulting in low precision that falls far short of industrial CT inspection standards. While current CT technology relies on a precision-moving inspection platform to hold and support the workpiece, limitations in the platform's ability to grip the workpiece create blind spots at many gripping points. Furthermore, the platform's obstruction limits imaging, restricting it to the left and right sides and preventing downward penetration. This prevents large-scale, unobstructed penetrating irradiation of the workpiece. Current CT technology performs individual workpiece inspections on a single platform, hindering automated, high-speed, automated inspection processes. Most existing X-ray automated inspection technologies employ a horizontal conveyor structure where radiation flows in from one inspection chamber and out from the other, divided into several inspection areas. This results in a large overall footprint, a bulky system, and significantly higher costs for radiation protection and equipment. Furthermore, the large footprint prevents its use in small spaces, leading to not only high costs and limited application, but also drawbacks such as low inspection accuracy, low efficiency, and a small inspection range. There is an urgent need for a compact CT inspection device with wide-area, unobstructed penetrating radiation capabilities and the ability to perform automated, high-speed automated inspection.

The positioning and rotation adjustment device 7 starts working and clamps the workpiece carrier tray 10 and the workpiece and rotates it. At the same time, the X-ray transmission angle adjustment mechanism 6 is started to adjust the X-ray machine and digital imaging plate for detection positioning. The X-ray machine and flat panel imager are turned on to start detection. After the detection is completed, the workpiece carrier tray 10 and the workpiece are lowered. The loading and unloading mechanism and the assembly line conveyor mechanism convey the workpiece carrier tray and the workpiece out from the top level.

[0037] The protective lead room 1 includes: a lead room body 11, an electrical control box 12, and a display control screen 13; the electrical control box 12 is connected to the upper rear of the lead room body 11, and the display control screen 13 is installed in front of the lead room body 11.

[0043] The assembly line conveying mechanism 4 includes: an assembly line frame 41, an upper conveying roller 42, a lower conveying roller 43, and a drive motor 44. Multiple sets of upper conveying rollers 42 and lower conveying rollers 43 are installed on the upper and lower layers of the assembly line frame 41, respectively. The drive motor 44 is installed on the assembly line frame and is connected to the conveying rollers to complete the conveying and transmission work.

[0044] The conveyor system 4 is a vertical conveyor structure with two layers. It works in conjunction with the loading and unloading mechanism 5 to convey the workpiece tray 10 and the workpiece into the inspection chamber via the lower conveyor roller 43 on the lower layer of the conveyor system. After the inspection is completed, the workpiece tray 10 and the workpiece are lifted and pushed out by the loading and unloading mechanism 5 via the upper conveyor roller 42 on the upper layer of the conveyor system.

[0045] Among them, the production line lead door 2 includes: production line lead door 21, production line lead door 22, and production line inner lead door 23; the production line lead door 2 is opened and closed sequentially according to the testing process.

[0046] The loading and unloading mechanism 5 includes: a loading and unloading bracket 51, a loading lifting mechanism 52, a loading and unloading pushing device 53, and a bracket clamping and fixing device 54.

The loading and unloading bracket 51 is equipped with a bracket clamping and fixing device 54. The bracket clamping and fixing device 54 can drive and adjust the width of the loading and unloading bracket 51 to adapt to the requirements of different specifications of workpieces.

[0047] The loading and unloading bracket 51 employs a flexible connection method, including elastic fabric tape connection, telescopic spring connection, and pneumatic cylinder elastic clamping connection. This allows it to adapt to the requirements of continuous multi-part, multi-angle zoned inspection of workpieces within a specified range. The bracket clamping and fixing device can quickly and accurately clamp the inspected workpiece, ensuring that parts of different sizes and structures are fixed and clamped without deflection or displacement.

The upper end of the rotation mechanism 64 is equipped with an imaging plate mounting bracket 68, on which a fixed flat panel imager 9 is mounted. The X-ray illumination angle adjustment mechanism 6, through the lifting mechanism 62, lifts the lifting connecting plate 63 up and down. The angle rotation mechanism 64 on the lifting connecting plate 63 drives the equipment connecting frame 65 to adjust according to the set angle, thereby driving the X-ray machine mounting bracket 66 and the X-ray machine 8 mounted on it to adjust the detection illumination angle. The imaging plate moving mechanism 67 moves laterally to adjust its position, while simultaneously driving the angle rotation mechanism 64 to rotate, driving the imaging plate mounting bracket 68 to rotate and correspondingly adjust the detection illumination angle of the X-ray tube 8. This mechanism can realize the continuous and accurate displacement adjustment of the position of the X-ray source and the flat panel detector relative to the workpiece according to the illumination requirements of different areas and angles of the workpiece to be inspected. It is safe and reliable during operation and is equipped with safety anti-collision measures to ensure that the X-ray source and detector will not collide with the workpiece or other mechanisms during the angle and position conversion process.

[0049] During the teaching process, the angle and position of the X-ray source and flat panel imager can be adjusted through the control software while the lead room is closed; after the X-ray procedure is determined, the program can be retrieved and automatically adjusted to the required X-ray angle.

[0051] Among them, the tray 71 is marked with a 0 mark. The tooling fixture is designed to clamp and fix the workpieces within the diameter range of Φ (100-600) mm, so as to ensure the 0 point of the workpiece radiography during the loading stage.

[0052] The drive motor is connected to the upper conveyor roller 42 and the lower conveyor roller 43 by a toothed belt or a chain.
