Description

TECHNICAL FIELD

[0002] As an advanced non-destructive testing method, industrial CT technology has been widely used in aerospace, automobile manufacturing, electronics, precision casting, new energy and other fields. It can clearly, accurately and intuitively obtain the three-dimensional information of the internal structure, density, defects and assembly of the workpiece without damaging the workpiece.

[0003] A kind of industrial CT detection system is disclosed in Chinese patent with publication number CN109030522A, which includes a ray source, a turntable and a detector unit, the ray source and the detector unit are respectively arranged on the opposite sides of the turntable, and further includes a first mounting platform, a second mounting platform and a platform connecting frame, the first mounting platform and the second mounting platform are fixedly connected to the two opposite ends of the platform connecting frame, and the upper surfaces of the first mounting platform and the second mounting platform are in the same plane, the ray source is fixed to the upper surface of the first mounting platform, and the turntable and the detector unit are fixed to the upper surface of the second mounting platform. The mobility of the industrial CT detection system is enhanced, the moving cost is low, and the utilization rate is high.

[0004] However, the above detection system still has some deficiencies in the process of actual use: 1. The high-energy rays used in industrial CT detection are radioactive, and if not properly protected, they can easily harm the health of the operators. The radiation protection of existing equipment mainly relies on the overall closed detection box, but during the process of workpiece entering and exiting the box, the opening of the box door will increase the risk of radiation leakage. Although some devices try to set up a simple protective door, they still cannot effectively isolate the radiation while ensuring the normal entry and exit of the workpiece, and the protection effect cannot meet the safety standard requirements.

[0005] 2. The existing industrial CT detection equipment usually needs to manually carry the workpiece one by one to the detection area, and then manually carry it to the next link after the detection is completed. This method not only needs to consume a lot of labor cost, but also causes detection gaps during the carrying process of the workpiece, which cannot meet the needs of mass production. At the same time, the manual carrying process may also cause the workpiece surface to be contaminated with impurities, which will interfere with the penetration and reception of the rays during detection, and thus affect the clarity of the detection image, leading to false or missed defects.

DETAILED DESCRIPTION

[0033] The application will be described in greater detail in connection with the attached drawings, in which Figures 1-9 Embodiments of the application are described in detail, but the application can be implemented in many different ways within the scope defined by the claims.

[0034] The core purpose of the present application is to provide an industrial CT continuous online detection system, which can realize the continuous online detection of workpieces, complete the whole process of workpiece feeding, pretreatment, detection and discharging without manual intervention, greatly improve the detection efficiency; at the same time, by optimizing the radiation protection structure, effectively inhibiting the leakage of high-energy rays, ensuring the safety of the operating environment; in addition, by adding a workpiece cleaning and drying pretreatment link, eliminating the interference of surface impurities on the detection result, improving the detection accuracy.

[0035] And the core difference of the present application is the integrated design of cleaning and drying, radiation protection and continuous detection.

[0036] Embodiment one: Referring to Figure 1 and Figure 2 , an industrial CT continuous online detection system, comprising a static detection box 1, one side of the detection box 1 is provided with an opening.

[0037] The detection box 1 is the core bearing and protection body of the whole system, its overall structure is stable, which can provide reliable detection environment for the internal detection mechanism and workpiece. One side of the detection box 1 is provided with an opening, which is used to realize sealed connection with the controller 4, so as to ensure that the workpiece can be transferred from the controller 4 to the inside of the detection box 1 in a closed environment. The material of the detection box 1 is made of material with radiation protection performance, which can effectively block the diffusion of internal high-energy rays to the outside, further strengthening the radiation protection effect of the system.

[0038] Herein, Figure 1 and Figure 3 The difference lies in the controller 4.

[0039] Referring to Figure 2 , lifting detectors 2 are arranged on both sides along the length direction of the detection box 1.

[0040] The lifting detector 2 includes a high-energy ray source 20 for detecting the workpiece and detecting the internal defects thereof, and a receiving end 21 for receiving the high-energy ray source 20. The high-energy ray source 20 emits high-energy rays outward at equal intervals and is received by the receiving end 21, and images the inside of the workpiece in the process.

[0041] The bottom of the detection box 1 is provided with a mounting bracket 22 extending along the length direction of the detection box 1, which mainly provides mounting support for the lifting detector 2. The mounting bracket 22 is symmetrically provided with a vertical bracket 23 perpendicular to the bottom of the detection box 1, which provides a guide basis for the lifting movement of the lifting detector 2. The bottom of the detection box 1 also reserves a mounting position for the turntable 3, ensuring that the turntable 3 can be stably installed and realize the predetermined movement function. In addition, the side of the detection box 1 away from the controller 4 opening is provided with a discharge port 10, and the discharge port 10 is also provided with a continuous automatic conveyor 7, which is used to convey the workpiece after detection to the outside of the system.

[0042] Referring to Figure 2 The lifting detector 2 is the core executive component for realizing the internal defect detection of the workpiece, which mainly consists of a high-energy ray source 20 and a receiving end 21. The high-energy ray source 20 can emit high-energy rays for detection, and the intensity of the rays will change due to the difference in absorption ability of different structures in the workpiece during penetration of the workpiece. The receiving end 21 is used to receive the ray signal after penetrating the workpiece and convert it into an electrical signal, and then form a three-dimensional image of the internal workpiece through subsequent processing, so as to realize the identification and positioning of the internal defects of the workpiece.

[0043] The high-energy ray source 20 and the receiving end 21 are respectively installed on the vertical bracket 23 on the mounting bracket 22 at the bottom of the detection box 1, and they are always on the same horizontal plane, ensuring that the rays can be accurately emitted from the high-energy ray source 20 and captured by the receiving end 21. The vertical bracket 23 is provided with a vertical electric sliding rail 24 extending in the vertical direction, and the high-energy ray source 20 and the receiving end 21 are connected with the vertical electric sliding rail 24. Through the driving of the vertical electric sliding rail 24, the two can realize synchronous lifting movement. This lifting function makes the system can adapt to the detection requirements of workpieces with different height sizes, and only needs to adjust the height of the ray source and the receiving end 21, so as to ensure that the rays can cover the entire detection area of the workpiece.

[0044] Referring to Figure 2As shown, specifically, the rotary table 3 is arranged at the bottom of the detection box 1, and its main function is to support the workpiece and drive the workpiece to move in the XY axis direction, so as to adjust the relative position between the workpiece and the lifting detector 2, and ensure that the rays can fully scan each area of the workpiece. The installation base of the rotary table 3 is the mounting frame 22 arranged at the bottom of the detection box 1, and the mounting frame 22 is provided with a first horizontal electric sliding rail 25 extending in one direction, and the first horizontal electric sliding rail 25 is further provided with a second horizontal electric sliding rail 26 extending in another vertical direction, and the rotary table 3 is connected with the second horizontal electric sliding rail 26. Through the cooperative driving of the two layers of first horizontal electric sliding rail 25 and second horizontal electric sliding rail 26 which are perpendicular to each other, the rotary table 3 can drive the workpiece on it to move in any direction on the horizontal plane, so as to realize the accurate adjustment of the detection position of the workpiece.

[0045] The rotary table 3 is provided with rotary wheels 30 for supporting the workpiece, and each rotary wheel 30 is provided with an independent driving motor. The arrangement of the rotary wheel 30 not only can provide stable support for the workpiece, avoid shaking or damage of the workpiece during movement, but also can drive the workpiece to rotate under the driving of the motor. This rotation function enables the workpiece to realize 360-degree omnidirectional scanning during detection, ensures that there is no detection dead angle, and further improves the comprehensiveness and accuracy of detection.

[0046] Embodiment two: in order to further improve the accuracy and safety of the detection box 1 for detecting the workpiece, the controller 4 is further provided.

[0047] Referring to Figure 3 and Figure 4 ; specifically, the controller 4 is a key component for realizing continuous feeding, pretreatment and radiation protection of the workpiece, and the whole is a circular control box 40 structure, which is sealingly connected with the opening of the detection box 1 to form a closed transition area. The controller 4 is internally provided with three independent and isolated isolated cavities 47, which respectively undertake the functions of workpiece placement, workpiece cleaning and drying, and workpiece conveying connection. Through this partition design, the continuous processing of the workpiece can be realized, and the leakage of high-energy rays in the detection box 1 can be effectively inhibited.

[0048] The control box 40 of the controller 4 is provided with control ports 41 corresponding to the number of inner cavities, which are used for the entry and exit of workpieces and facilitate the daily maintenance of the equipment. Some of the control ports 41 are provided with sealing doors 42, which are in a closed state in the non-maintenance state of the equipment, further enhancing the sealing of the control box 40. The control box 40 is internally provided with a triangular support 43, which is installed at the center of the control box 40 through a rotating structure. The triangular support 43 is provided with rotating doors 44 corresponding to the three isolated inner cavities 47. The triangular support 43 is driven by a driving control member through a driving motor 45 to realize intermittent rotation, thereby driving the rotating doors 44 to rotate synchronously and completing the transfer of workpieces between different isolated inner cavities 47.

[0049] The triangular support 43 is also provided with a support frame 46, which functions to support the workpieces and ensure that the workpieces remain stable during rotation with the rotating doors 44. This not only reduces the weight of the support frame 46, but also facilitates the full contact of cleaning agents and gas with the surface of the workpieces during the cleaning and drying process, ensuring the pretreatment effect. Each rotating door 44 is provided with an isolation port 441, and the isolation port 441 is provided with symmetrically arranged isolation curtains 440. The isolation curtains 440 are made of flexible and sealing materials. When the workpieces enter or exit or the rotating doors 44 rotate, the isolation curtains 440 can automatically adhere to the workpieces or the inner wall of the control box 40, effectively blocking the spread of radiation between different isolated inner cavities 47, while not affecting the normal transfer of workpieces.

[0050] The inner wall of the detection box is lined with thick lead plates, and the outer wall is wrapped with boron-containing polyethylene plates (anti-scattering line). The isolation curtain is made of lead rubber material, the width matches the isolation port, and the edge is provided with a magnetic sealing strip to reduce radiation leakage.

[0051] In the inner cavity responsible for the cleaning and drying of workpieces, a fogging nozzle 50 is installed at the top. The fogging nozzle 50 is connected to a storage tank 52 provided at the top of the control box 40 through a fogging pipeline 51. The storage tank 52 contains cleaning agents for cleaning workpieces. A pump body is arranged on the fogging pipeline 51. Through the power of the pump body, the cleaning agents are transported to the fogging nozzle 50 and atomized, then uniformly sprayed onto the surface of the workpiece from top to bottom. The atomized cleaning agents can form fine droplets, fully covering all parts of the workpiece and effectively removing dust, oil stains and other impurities attached to the surface of the workpiece. The bottom of the inner cavity is also provided with a discharge port 63. The waste liquid and impurities generated during the cleaning process can be discharged through the discharge port 63 to avoid accumulation in the cavity.

[0052] Referring to Figure 5 , Figure 6 and Figure 7As shown, the bottom of the cleaning and drying inner cavity is also provided with an annular pipeline 60, which is uniformly provided with a plurality of air injection ports 61, which are also upwardly arranged. The annular pipeline 60 is connected with an air injection pump 62 arranged on the top of the control box 40 through an air injection pipeline. After cleaning, the air injection pump 62 is started to deliver dry and clean gas to the annular pipeline 60 through the air injection pipeline, and then the gas is uniformly injected to the surface of the workpiece through the air injection ports 61 to quickly blow and dry the remaining cleaning agent on the surface of the workpiece, so as to ensure that the surface of the workpiece is dry and free of residues, and avoid interference of impurities or liquid residues on subsequent detection.

[0053] The inner cavity which bears the workpiece conveying and connecting function is provided with a continuous automatic conveyor 7. The conveyor is used to transfer the workpiece after cleaning and drying pretreatment from the controller 4 to the turntable 3 in the detection box 1. At the same time, another continuous automatic conveyor 7 arranged at the discharge port 10 of the detection box 1 is used to transfer the workpiece after detection from the turntable 3 to the outside of the system, so as to realize automatic transfer of the workpiece in the whole process.

[0054] Referring to Figure 8 and Figure 9 As shown, the continuous automatic conveyor 7 is also arranged in the isolated inner cavity 47 close to the center of the detection box 1. The continuous automatic conveyor 7 includes a plurality of vertical supports 70 arranged in the detection box 1, and a control shaft 71 is arranged on each vertical support 70. The control shaft 71 is provided with a conveying sprocket 72 at both ends, and the conveying sprocket 72 is provided with two symmetrical conveying chains 73.

[0055] The conveying chain 73 is provided with an inclined auxiliary plate 74 on one side of the isolated inner cavity 47 of the control box 40.

[0056] The continuous automatic conveyor 7 mainly includes the vertical support 70, the control shaft 71, the conveying sprocket 72 and the conveying chain 73. The vertical support 70 is fixedly arranged in the inner cavity of the controller 4 or at the discharge port 10 of the detection box 1, and a plurality of vertical supports 70 are arranged in parallel to provide stable support for the control shaft 71. The control shaft 71 is transversely arranged on the vertical support 70, and the conveying sprocket 72 is arranged at both ends of the control shaft 71. The conveying sprocket 72 on the same side is provided with the conveying chain 73, forming a symmetrical double-chain conveying structure. This double-chain structure can provide stable support for the workpiece, so as to ensure that the workpiece will not deviate or fall during conveying.

[0057] The continuous automatic conveyor 7 in the inner cavity of the controller 4 is close to one side of the turntable 3, and is provided with an inclined auxiliary plate 74. The inclination angle of the inclined auxiliary plate 74 is optimized and designed, which can guide the workpiece to smoothly transition from the conveying chain 73 to the turntable 3, avoid collision or damage of the workpiece in the transfer process due to height difference, and ensure the stability and continuity of the conveying. The conveying chain 73 is driven to circulate by a driving device, and the workpiece is driven to move forward by the friction between the conveying chain 73 and the workpiece, realizing the continuous conveying of the workpiece, and the conveying speed can be adjusted according to the overall detection rhythm, ensuring that it matches the rotation rhythm of the controller 4 and the detection rhythm of the turntable 3, and realizing the cooperative operation of the whole system.

[0058] When working, the specific working process is as follows: First step: workpiece feeding and radiation isolation: the operator puts the workpiece to be detected into the first isolated inner cavity 47 through the control port 41 of the controller 4, and the workpiece is placed on the support frame 46; then the sealing door 42 is closed, the isolated inner cavity 47 forms a closed space, effectively blocks the leakage of high-energy rays in the detection box 1 to the outside, and ensures the operation safety.

[0059] Second step: intermittent rotation and cleaning and drying: the precision motor 45 drives the triangular support 43 to drive the rotating door 44 to rotate intermittently, and the support frame 46 carrying the workpiece to be detected is rotated to the second isolated inner cavity 47; at this time, the pump body starts to work, the cleaning agent in the storage tank 52 is conveyed to the atomizing nozzle 50 through the atomizing pipeline 51 and is atomized, and is uniformly sprayed to the surface of the workpiece, so that the surface of the workpiece is cleaned comprehensively; after cleaning, the pump body stops working, the air jet pump 62 starts to work, dry gas is sprayed from the air jet port 61 through the air jet pipeline and the annular pipeline 60, the residual cleaning agent on the surface of the workpiece is quickly blown dry, and the waste liquid and impurities generated in the cleaning process are discharged through the discharge port 63.

[0060] Third step: workpiece conveying to the turntable 3: the triangular support 43 continues to rotate, and the workpiece after cleaning and drying is transferred to the third isolated inner cavity 47; at this time, the continuous automatic conveyor 7 in the inner cavity starts to work, and the conveying chain 73 drives the workpiece to move towards the detection box 1, and under the guidance of the inclined auxiliary plate 74, the workpiece smoothly transitions to the turntable 3 at the bottom of the detection box 1.

[0061] Fourth step: accurate detection: the turntable 3 drives the workpiece to move in the XY axis direction according to the preset detection program, and the rotating wheel 30 on the turntable 3 drives the workpiece to rotate; the lifting detector 2 adjusts the height of the high-energy ray source 20 and the receiving end 21 through the vertical electric sliding rail 24, so that the height of the high-energy ray source 20 and the receiving end 21 matches the detection height of the workpiece. The high-energy ray source 20 emits rays to penetrate the workpiece, the receiving end 21 receives the ray signal and converts it into an image signal, and generates a three-dimensional image of the inside of the workpiece through subsequent processing, and completes the defect detection.

[0062] The fifth step is workpiece discharging: after detection, the turntable 3 moves the workpiece to the continuous automatic conveyor 7 at the discharging port 10 of the detection box 1, and the continuous automatic conveyor 7 is started to convey the workpiece to the outside of the system, completing the entire detection process. In the above process, the rotary door 44 of the controller 4 continuously and intermittently rotates, and new workpieces to be detected are continuously fed into the first inner cavity, realizing continuous feeding, pretreatment and detection of the workpieces, and forming an uninterrupted online detection mode.
