Description

Technical Field

[0001] This patent relates to the field of X-ray DR and CT non-destructive testing of carbon-carbon composite material workpieces, and in particular to an automatic loading and unloading X-ray DR / CT detection device for carbon-carbon composite materials. Background Art

[0002] Carbon-carbon composites are a new type of ultra-high-temperature thermal structural material currently being researched and developed in the new materials field. They feature low density, high specific strength, low linear expansion coefficient, high thermal conductivity, and excellent ablation and wear resistance. They are widely used in aerospace, automotive, medical, and other fields. Internal defects can occur during the manufacturing process. Currently, domestic carbon-carbon composite material inspection primarily uses traditional X-ray DR digital imaging to detect defects in carbon-carbon composites. This method uses manual loading and unloading, requiring workers to frequently enter and exit the inspection room, resulting in low inspection efficiency and high workload. Researchers have detected defective workpieces using DR real-time imaging inspection equipment. If CT three-dimensional scanning imaging is required for further research on internal defect deformation, the defective workpiece needs to be taken to an independent CT device for three-dimensional imaging inspection and analysis. Not only is the inspection intensity high, but the manual operation is complicated and the inspection efficiency is extremely low, which cannot meet the existing production inspection needs. There is an urgent need for a dual-station automatic loading and unloading high-efficiency inspection system that integrates X-ray DR real-time imaging detection and CT three-dimensional scanning detection. DR can quickly detect whether the workpiece has defects, and CT detection technology can be used to conduct detailed analysis of the location and size of defects in carbon-carbon composite materials, helping researchers analyze the causes of defects and thus improve the process.

[0003] The assembly line automatic loading and unloading DR / CT inspection device combines automatic assembly line loading and unloading technology with DR / CT inspection technology. Compared with traditional CT inspection, it is faster and more convenient. Therefore, an assembly line automatic loading and unloading dual-station X-ray DR / CT inspection device can automatically complete the inspection with one loading, reducing the operator's frequent loading and unloading, reducing labor intensity, reducing the number of personnel entering and exiting the inspection room, saving time, and improving inspection efficiency.

A loading assembly line 110 is provided side by side on the lower right side of the rotary moving detection assembly line 113. A reversing mechanism 112 is provided between the discharge assembly line 111 and the loading assembly line 110. A workpiece tooling pallet 114 is installed on the high-precision turntable moving mechanism 109.

[0030] The X-ray tube lifting and moving mechanism 101 is a standard LEX CT450-Z marble electric lifting and moving mechanism, on which an X-ray tube 102 is mounted. The mechanism can carry the X-ray tube 102 and move it left and right to adjust the focal length of the radiation, and can also move it up and down in the height direction to meet the needs of adjusting the detection position.

[0031] An electric collimator 103 is installed at the front end of the ray window of the X-ray tube 102. It can automatically switch between cone beam and fan beam according to detection needs.

[0032] The detector lifting and moving mechanism 104 is a standard LEX CT450-Z marble electric lifting and moving mechanism, on which an area array detector 105 and a linear array detector 106 are installed. It can carry the area array detector 105 and the linear array detector 106 to move along the left and right directions to adjust to the position of the detection workpiece, and can also be lifted and lowered in the height direction to meet the needs of adjusting the detection position.

[0033] A dual-imager setup is employed on the detector lifting and moving mechanism 104. Two imaging devices, an area array detector 105 and a linear array detector 106, are provided at the front end of the moving mechanism. The area array detector 105 and the linear array detector 106 are placed horizontally side by side to enable real-time switching between DR and CT detection of the workpiece.

[0034] Four electric gratings 107 are installed in front of the area array detector 105 , and a collimator 108 is installed at the front end of the linear array detector 106 .

[0035] The high-precision turntable moving mechanism 109 includes: a bottom marble frame 201, a longitudinal guide rail 202, a longitudinal guide rail moving mechanism 203, a rotating mechanism 204, and a rotating disk 205; the bottom marble frame 201 is set on the ground in the middle, and a longitudinal guide rail 202 is installed on the bottom marble frame 201, and a longitudinal guide rail moving mechanism 203 is installed at the lower end of the longitudinal guide rail 202, and a rotating mechanism 204 is installed on the longitudinal guide rail moving mechanism 203, and a rotating disk 205 is installed on the rotating mechanism 204.

[0036] The rotary motion inspection line 113 is a standard DRI CA 225-B double-speed chain-type assembly line. Its base is mounted on the longitudinal guide rails 202 of the high-precision turntable moving mechanism 109. Sharing the same set of linear guide rails as the high-precision turntable moving mechanism 109, it can be controlled to move along the guide rails, switch positions, and load and unload materials. A lifting and rotating transmission mechanism is located in the lower middle portion of the rotary motion inspection line 113. After the loading line 110 transfers the workpiece pallet 114 to the rotary motion inspection line 113, the rotary motion inspection line 113 moves to the inspection position. A lifting and rotating mechanism is located in the lower middle portion of the rotary motion inspection line 113. Once lifted, it engages with the connecting flange 304 of the workpiece tooling pallet 114, thereby driving the small workpiece to rotate synchronously for inspection. After inspection, the rotary motion inspection line 113 moves to the unloading position and transfers the workpiece pallet 114 to the unloading line 111.

[0037] The loading line 110 adopts a standard DRI CA 225-B double-speed chain line, and can transfer the workpiece pallet 114 through program control.

[0038] The unloading assembly line 111 adopts a standard DRI CA 225-B double-speed chain assembly line, and can transfer the workpiece pallet 114 through program control.

[0039] The reversing mechanism 112 adopts a standard DRI CA 225-H toothed belt assembly line, and can be controlled by a program to reversingly transmit the workpiece pallet 114 so that the workpiece tooling pallet 114 is transported from the loading assembly line 110 to the unloading assembly line 111.

[0040] The workpiece tooling pallet 114 includes a pallet base 301, a support plate 302, connecting screws 303, a rotating interlocking flange 304, a drive shaft 305, an interlocking gear 306, and a small workpiece pallet 307. The support plate 302 is fixed to the pallet base 301 via the connecting screws 303. A drive shaft 305 is provided in the middle of the support plate 302. The drive shaft 305 is fixed via a bearing. The lower end of the drive shaft 305 is connected to the rotating interlocking flange 304. The middle of the drive shaft 305 is provided with an interlocking gear 306, which interlocks with the adjacent gear. The upper end of the drive shaft 305 is connected to a small workpiece pallet 307, which carries small workpieces for testing. During testing, the rotating interlocking flange 304 is connected to the lifting and rotating transmission mechanism in the middle and lower part of the rotating and moving testing assembly line 113. Through the mutual transmission of the interlocking gears 306, it drives all workpiece pallets 307 carrying small workpieces for rotation testing.

[0041] The small workpiece tray 307 is made of polyurethane material. The material of the small workpiece tray 307 is uniform and does not affect the radiation penetration detection, and can avoid collision and damage to the workpiece.

[0042] The tooling tray 114 is provided with 12 small workpiece trays 307 , each of which can carry a standard small workpiece. The tooling tray 114 can carry 12 workpieces at a time, and can perform inspections with high efficiency.

[0043] The loading line 110 can hold 10 sets of assembly line workpiece tooling pallets 114. The loading line 110 transports the assembly line workpiece tooling pallets 114 to the rotating and moving detection line 113. The rotating and moving detection line 113 moves to the detection position to perform DR detection of the workpiece. After defects are found, CT imaging detection is performed on the spot.

[0044] The non-standard large workpiece is placed on the rotating disk 205 of the high-precision turntable moving mechanism 109, and the high-precision turntable moving mechanism 109 is driven to complete the DR inspection of the large workpiece. After the defects are found, CT imaging inspection is performed on the spot.

[0045] The loading and unloading lines are double-speed chain-type lines. A reversing mechanism is installed at one end, allowing workpiece pallets 114 to be transported from loading line 110 to unloading line 111. The other end interfaces with a rotating, mobile inspection line 113. This rotating, mobile inspection line 113 can be docked with both loading and unloading lines 110 and 111, enabling automatic loading and unloading of workpieces. Twelve rotating tables are installed on workpiece pallet 114. Once the workpiece pallet 114 is transported to a designated location on the inspection line, it connects to a rotating mechanism, driving the 12 rotating tables to rotate synchronously.

[0046] The inspection device is a dual-station setup. The high-precision turntable movement mechanism 109 is used for DR / CT inspection of large workpieces. The high-precision turntable can move perpendicular to the beam. The rotary motion inspection line is used for DR / CT inspection of batches of small workpieces. The rotary motion inspection line and the high-precision turntable share the same set of linear guides.

[0049] Step 3: Turn on the X-ray tube 102, turn on the area array detector 105 to perform real-time imaging DR detection on the workpiece, turn off the area array detector 105 after the real-time imaging DR detection is completed, turn on the linear array detector 106 when a defective workpiece is found, and perform CT scanning on the defective workpiece, and turn off the X-ray tube 102 and the linear array detector 106 after the completion of the CT scanning.

[0050] Step 4: Drive the rotating mobile inspection line 113 to carry the workpiece tooling tray 114 to the corresponding position of the unloading line 111, transport the workpiece tooling tray 114 to the material line 111, and then move the rotating mobile inspection line 113 to the corresponding position of the loading line 110 to perform the second step of the loading operation;

[0051] Step 5: After all the workpieces on the loading line 110 have been inspected, turn off the X-ray and imaging system, open the lead door 3, remove the inspected workpieces, and re-place a new batch of workpieces for inspection.

[0052] A method for inspecting large, non-standard workpieces using an automatic loading and unloading X-ray DR / CT inspection device for carbon-carbon composite materials: Step 1: Clamp the large, non-standard workpiece onto the rotating disk 205, close the lead door 3 of the inspection chamber 4, and control the operating table 2 in the operating chamber 1 to drive and adjust the X-ray tube lifting mechanism 101 and the detector lifting mechanism 104 to their initial working positions.
