Description

Technical Field

[0001] This utility model relates to the field of X-ray nondestructive testing technology, specifically to a sample stage and testing system for X-ray testing. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] The application of X-ray nondestructive testing in scientific research and industry is becoming increasingly mature. With the deepening of applications and the refinement of various testing standards, the market has higher requirements for the efficiency and testing accuracy of X-ray nondestructive testing equipment.

[0004] For typical X-ray nondestructive testing (NDT) equipment, the object being inspected needs to be rotated. If the application is for online inspection, the object also needs to be moved and transported in various ways. Existing X-ray NDT equipment generally has a turntable, with a track installed above the turntable and an electric slip ring installed below it. The turntable provides rotational motion for the object being inspected, the track facilitates the transport of the object, and the electric slip ring provides power to the track.

[0005] For similar X-ray detection and imaging devices, the above scheme has several disadvantages: (1) The track cannot clamp and fix the object to be detected. During the rotation of the turntable, the object to be detected may move, resulting in low detection accuracy; (2) The use of electric slip rings requires the size of the electric slip rings to match the size of the turntable, which increases the initial design and procurement costs. In particular, when the material to be detected is large and the turntable size is large, a larger electric slip ring needs to be used, which increases the equipment cost; (3) The carbon brushes used for current transmission of electric slip rings are consumables and need to be replaced after long-term use, which increases the cost of use in the later stage. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sample stage and detection system for X-ray detection, which can clamp and fix the sample, improve the detection accuracy, and at the same time avoid the use of electric slip rings, thus reducing equipment costs.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: In a first aspect, embodiments of this utility model provide a sample stage for X-ray detection, including a hollow rotary platform. A stage is fixed to the rotating part of the hollow rotary platform. Clamping mechanisms are provided on both sides of the sample placement area of ​​the stage. The clamping mechanisms can operate in a clamping state when the power is off. The rotating part of the hollow rotary platform is also provided with a first conductive component via a first bracket. The first conductive component is connected to the power supply circuit of a push-pull electromagnet telescopic rod. A second conductive component is fixedly provided on one side of the hollow rotary platform. The second conductive component matches the first conductive component. The second conductive component is slidably connected to a guide post. The guide post is fixed on a second bracket. An elastic element is provided between the second conductive component and the second bracket. The second conductive component is connected to a power supply. The hollow rotary platform can drive the first conductive component to move so as to switch the contact and separation states of the first and second conductive components.

[0008] Optionally, the clamping mechanism adopts a push-pull electromagnet telescopic rod that extends when power is off.

[0009] Optionally, the second bracket includes a frame, the frame being provided with a protective plate made of insulating material, one side of the protective plate being fixed to the frame, and the other side being provided with a mounting plate, the mounting plate being fixedly connected to one end of a guide post, and the guide post passing through a second conductive component and being slidably connected to the second conductive component.

[0010] Optionally, one end of the guide post is connected to the second bracket, and the other end is provided with a stop block, which can contact the second conductive component to restrict the movement of the second conductive component.

[0011] Optionally, the elastic element is a spring, with one end of the spring connected to the second bracket and the other end of the spring connected to the second conductive component.

[0012] Optionally, the second conductive component is provided with a spring groove, and the end of the spring extends into the spring groove.

[0013] Optionally, buffer blocks fixed to the first bracket are provided on both sides of the first conductive component, and the buffer blocks are made of flexible insulating material.

[0014] Optionally, the side of the buffer block away from the first support is V-shaped, and the sharp corner of the V-shaped surface is set in the direction away from the first support.

[0015] Optionally, the rotating part of the hollow rotary platform is also equipped with a baffle, and a photoelectric sensor that is fixedly installed on one side of the hollow rotary platform and cooperates with the baffle is provided.

[0016] Secondly, embodiments of this utility model provide an X-ray detection system, including the X-ray detection sample stage described in the first aspect, a radiation source located below the hollow rotary platform, and a detector located above the stage. It also includes a robotic arm for placing or removing materials to be tested from the stage, with a material fixing mechanism at the end of the robotic arm.

[0017] Thirdly, embodiments of this utility model provide a method for operating the X-ray detection system described in the second aspect: After the hollow rotary platform rotates to contact the first conductive component and the second conductive component, it stops rotating. The power supply circuit of the power supply and the clamping mechanism are connected, the clamping mechanism is energized, and the clamping state is released. The robotic arm places the material to be tested onto the platform; The hollow rotary platform continues to rotate, and the X-ray source is activated at the same time. The first and second conductive components separate, the clamping mechanism is de-energized, and the material is clamped. At the same time, the X-ray source emits X-rays, and the material is subjected to non-destructive X-ray testing while the hollow rotary platform rotates. After the inspection is completed, the hollow rotary platform rotates, causing the first and second conductive components to come into contact. The clamping mechanism is energized, releasing the clamping state, and the robot arm removes the inspected material from the platform.

[0018] The beneficial effects of this utility model are as follows: 1. The sample stage for X-ray object inspection of this utility model has clamping mechanisms on both sides of the material placement area of ​​the stage. In the power-off state, the clamping mechanisms operate in a clamping state to clamp the material. During the material rotation detection process, the material will not move, ensuring the detection accuracy of the material. At the same time, through the setting of the first conductive component and the second conductive component, the clamping mechanism is only released when the material needs to be picked up or put down. The first conductive component and the second conductive component cooperate to supply power to the clamping mechanism, eliminating the need for slip rings and reducing the initial design and equipment procurement costs. The first conductive component and the second conductive component do not use consumables such as carbon brushes and are non-consumables, reducing the later maintenance costs of the equipment.

[0019] 2. The X-ray inspection system of this utility model eliminates the need for a track and instead incorporates a robotic arm. The robotic arm is used to place materials onto and remove them from the platform, thus enabling online inspection of the materials. Attached Figure Description

They do not limit the structure and are merely for the purpose of describing this utility model and simplifying the description.

Therefore, they should not be construed as limitations on this utility model.

[0022] Example 1 This embodiment provides a sample stage for X-ray detection, such as... Figure 1 As shown, the device includes a hollow rotary platform 1. The rotating part of the hollow rotary platform 1 is equipped with a platform 2, which can drive the platform 2 to rotate. The platform 2 is used to place the material to be tested. The hollow rotary platform 1 has a space inside for X-rays to pass through. The platform 2 has a material placement area for placing the material to be tested. In this embodiment, instead of a track, a clamping mechanism is provided on the platform 2. At least one clamping mechanism is provided on both sides of the material placement area. The clamping mechanisms on both sides can clamp and fix the material, so that the material can only rotate with the hollow rotary platform 1 and will not move otherwise, thus ensuring the accuracy of the test. The rotating part of the hollow rotary platform 1 is also connected to the first conductive component 4 through the first bracket 3. The first conductive component 4 is connected to the power supply circuit of the clamping mechanism. A second bracket 5 is also provided on one side of the hollow rotary platform 1. The second bracket 5 is equipped with a guide post 6. The guide post 6 is slidably connected to the second conductive component 7, and an elastic element is provided between the second conductive component 7 and the second bracket 5. The second conductive component matches the first conductive component and is connected to the power supply.

[0023] The first conductive component 4 can rotate together with the hollow rotary platform 1. The power supply circuit of the clamping mechanism forms a disconnection point between the first conductive component 4 and the power supply. When the first conductive component 4 and the second conductive component 7 come into contact, the power supply circuit of the clamping mechanism is connected to the power supply, thereby enabling the power supply to supply power to the clamping mechanism.

[0024] The hollow rotary platform 1 can be made using existing equipment, and will not be described in detail here. The fixed part of the hollow rotary platform 1 is fixed on the fixed plate 8. The fixed plate 8 has a through hole coaxial with the internal space of the hollow rotary platform 1 for the passage of X-rays.

[0025] In this embodiment, the stage 2 is made of a flat plate that can pass through X-rays, such as an aluminum plate or a carbon fiber plate. The thickness of the stage should meet the requirements for X-ray penetration. The stage 2 is coaxially and fixedly connected to the rotating part of the hollow rotary platform 1, and can rotate around its own axis under the drive of the hollow rotary platform 1.

[0026] The upper surface of the stage 2 is provided with a material placement area, and a groove is provided in the material placement area for placing the material to be tested.

[0027] At least one clamping mechanism is provided on each of the opposite sides of the groove. In this embodiment, two clamping mechanisms are provided on each side of the groove. The corresponding clamping mechanisms are coaxially arranged to ensure the firmness of the clamping of the material.

[0028] In this embodiment, the clamping mechanism adopts a push-pull type electromagnet telescopic rod 9 that can extend when the power is off. It has components such as electromagnet, telescopic rod and spring. When the electromagnet is energized, the telescopic rod retracts under the action of the electromagnet's magnetic force, overcoming the elastic force of the spring, and is in a non-clamping state. When the electromagnet is de-energized, the telescopic rod extends under the action of the spring, can clamp the material, and is in a clamping state. The push-pull type electromagnet telescopic rod 9 can use existing equipment, and its specific structure will not be described in detail here.

[0029] The push-pull electromagnet telescopic rod 9 is also unaffected by X-rays and can work normally.

[0030] The push-pull electromagnet telescopic rod 9 is installed in the mounting slot provided on the platform 2. The mounting slot is connected to the side of the groove. The power supply line of the push-pull electromagnet telescopic rod 9 is connected to the corresponding first conductive component 4, and a disconnection point with the power supply is formed at the first conductive component 4.

[0031] In this embodiment, as Figures 2-3As shown, the first support 3 includes a horizontal plate. The inner end of the horizontal plate is fixedly connected to the rotating part of the hollow rotary platform. The outer end of the horizontal plate is provided with a vertical plate. The vertical plate is provided with a plurality of first conductive components. The number of first conductive components 4 corresponds to the number of push-pull electromagnet telescopic rods 9. Each push-pull electromagnet telescopic rod 9 corresponds to one first conductive component 4.

[0032] Furthermore, multiple reinforcing plates are provided between the vertical plate and the horizontal plate to increase the overall structural strength of the first support 3.

[0033] The first conductive component 4 is fixedly connected to the vertical plate via a connecting block. The first conductive component 4 includes a first fixing block made of insulating material. The first fixing block can be made of existing insulating material, which will not be described in detail here. For example, the first fixing block can be made of plastic. The power supply wire of the push-pull electromagnet telescopic rod 9 passes through the first fixing block and is exposed on the outer side of the first fixing block so that the wire of the push-pull electromagnet telescopic rod 9 can be connected to the power supply.

[0034] The first conductive component 4 has buffer blocks 10 fixed to the first bracket 3 on both sides. The buffer blocks 10 are integrally connected with the connecting block. Therefore, the connecting block and the buffer block are made of the same material. The buffer blocks 10 protrude from the outer side of the first conductive component 4. The buffer blocks 10 are made of flexible insulating material, preferably rubber material. The inner side of the buffer blocks 10 is fixedly connected to the vertical plate. The outer side is a V-shaped surface, and the sharp corner of the V-shaped surface is set to the outward direction. The V-shaped surface facilitates the sliding of the second conductive component 7 along the guide post 6 after contact with the second conductive component 7.

[0035] In another embodiment, the outer edge of the outer side of the buffer block 10 is provided with a rounded chamfer.

[0036] The second conductive component 7 is mounted on the second bracket 5, which is fixedly mounted on one side of the hollow rotary platform.

[0037] like Figures 4-5 As shown, the second support 5 includes a frame, which includes a horizontal plate. The horizontal plate is fixedly installed, and a vertical plate is provided at one end of the horizontal plate. The vertical plate is arranged tangentially along the circumference of the hollow rotating platform. The surface of the vertical plate facing the hollow rotating platform is provided with a second conductive component 7. The number of the second conductive components 7 matches the number of the first conductive components 4.

[0038] The second conductive component 7 adopts a second fixing block, which is made of insulating material such as plastic. The second fixing block is a T-shaped block with a protruding structure in its middle. A wire connected to the power supply passes through the protruding structure and is exposed to the outside. When the protruding structure contacts the first fixing block, the wire connected to the power supply can make contact with the corresponding wire connected to the push-pull electromagnet telescopic rod 9 to conduct electricity, thereby realizing the power supply to the push-pull electromagnet telescopic rod 9.

[0039] The two edges of the outer side of the protruding structure are provided with beveled chamfers, so that when the second conductive component 7 comes into contact with the buffer block 10, the second conductive component 7 can slide along the guide post.

[0040] In the second fixing block, guide posts 6 pass through the parts on both sides of the protruding structure. The guide posts 6 are also made of insulating material, such as plastic. One end of the guide post 6 is fixed to the mounting plate 11. The mounting plate 11 is fixed to one side of the guard plate 12. The other side of the guard plate 12 is fixed to the vertical plate of the frame. The guard plate 12 is made of insulating material, such as plastic.

[0041] An elastic element is provided between the second fixing block and the mounting plate 11. In this embodiment, the elastic element is a spring 13.

[0042] Spring 13 is sleeved on the outer periphery of guide post 6, with one end abutting or fixedly connected to the second fixing block and the other end abutting or fixedly connected to the mounting plate.

[0043] Furthermore, the side of the second fixing block connected to the spring 13 is provided with a spring groove. The end of the spring 13 extends into the spring groove and abuts or is fixedly connected to the groove surface of the spring groove. The spring groove can be used to position the spring 13, which facilitates the installation of the spring.

[0044] Furthermore, the end of the guide post 6 is also provided with a stop 14, which can contact the second conductive component 7 to prevent the spring 13 from pushing the second conductive component 7 off the guide post 6.

[0045] In this embodiment, the hollow rotary platform 1 drives the first support 3 and the first conductive component 4 to move. When the first conductive component 4 cooperates with the second conductive component 7, the push-pull electromagnet telescopic rod 9 is energized. At this time, the hollow rotary platform 1 needs to stop rotating in order to pick up or put down materials.

[0046] To achieve automatic control here, a sensor bracket 15 is provided at a set position on one side of the hollow rotary platform 1. The sensor bracket 15 is fixed on the fixed plate 8. A photoelectric sensor 16 is provided at the top of the sensor bracket 15. Correspondingly, the rotating part of the hollow rotary platform 1 is provided with a baffle 17 for cooperating with the photoelectric sensor 16.

[0047] The positions of the photoelectric sensor 16 and the baffle 17 are such that when the baffle 17 moves above the photoelectric sensor 16 to block it, the first conductive component 4 and the second conductive component 7 can make perfect contact and cooperate.

[0048] The photoelectric sensor 16 and the hollow rotary platform 1 are both connected to the control system 18. The photoelectric sensor 16 can transmit the detected signal to the control system 18, and the control system 18 can control the hollow rotary platform 1 to work.

[0049] The working method of this embodiment is as follows: In the initial state, the first conductive component 4 and the second conductive component 7 are not in contact. At this time, the push-pull electromagnet telescopic rod 9 is de-energized, its telescopic rod extends and is in a clamping state, and the control system 18 controls the hollow rotating platform 1 to work. When the baffle 17 rotates to be directly above the photoelectric sensor 16, the first conductive component 4 and the second conductive component 7 are in contact. The process is that the protruding structure of the second conductive component 7 first contacts the buffer block 10 on one side. Under the action of the buffer block 10, the second conductive component 7 slides along the guide post, so that the protruding structure can pass over the buffer block 10. When the protruding structure corresponds to the first conductive component 4, under the action of the spring 13, the second conductive component 7 moves toward the first conductive component 4, so that the protruding structure of the second conductive component 7 contacts the first conductive component 4, and the power supply wire contacts and conducts with the corresponding wire of the push-pull electromagnet telescopic rod 9.

[0050] After the first conductive component 4 and the second conductive component 7 come into contact, the control system 18 receives the signal from the photoelectric sensor 16 and controls the hollow rotary platform 1 to stop rotating. The power supply circuit of the push-pull electromagnet telescopic rod 9 is connected. After the push-pull electromagnet telescopic rod 9 is energized, it retracts and releases the clamping state. At this time, the material is placed on the platform 2. After the material is placed, the control system 18 controls the hollow rotary platform 1 to continue rotating. The first conductive component 4 and the second conductive component 7 disengage. The push-pull electromagnet telescopic rod 9 is de-energized and extends, switching to the clamping state to clamp and fix the material. The material rotates with the platform 2 to perform material detection.

[0051] After the test is completed, the hollow rotary platform 1 rotates until the first conductive component 4 and the second conductive component 7 are in contact. The hollow rotary platform 1 stops rotating, and the push-pull electromagnet telescopic rod 9 is energized and retracts. At this time, the material that has been tested can be removed.

[0052] In this embodiment, the sample stage 2 has clamping mechanisms on both sides of the material placement area. In the power-off state, the clamping mechanisms operate in a clamping state to hold the material tightly. During the material rotation detection process, the material will not move, ensuring the detection accuracy of the material. At the same time, through the setting of the first conductive component 4 and the second conductive component 7, the clamping mechanism is only released when the material needs to be picked up or put down. The first conductive component 4 and the second conductive component 7 work together to supply power to the clamping mechanism, eliminating the need for slip rings and reducing the initial design and equipment procurement costs. The first conductive component 4 and the second conductive component 7 are non-consumables, reducing the later maintenance costs of the equipment.

[0053] Example 2 This embodiment provides an X-ray detection system, including the X-ray detection sample stage described in Embodiment 1. A radiation source 19 is provided below the fixed plate, and a detector 20 is provided above the stage 2. The detector 20 is connected to the control system 18 and can convert X-ray energy into electrical signals and transmit them to the control system.

[0054] The radiation source 19 can be any existing device, such as any suitable apparatus capable of generating, for example, X-rays. In this embodiment, the radiation generated from the radiation source 19 and ultimately reaching the detector is a cone beam.

[0055] Detector 20 can be made from existing equipment; it is any suitable device capable of converting X-ray energy into an electrical signal.

[0056] The X-ray source 19 and detector 20 can be based on existing equipment, and will not be described in detail here.

[0057] It also includes a robotic arm, which is used to place the material to be tested into the platform 2 or remove it from the platform. The end of the robotic arm is equipped with a material fixing mechanism for fixing the material.

[0058] The material fixing mechanism uses a vacuum suction cup. Existing technology can be used for the vacuum suction cup, which will not be described in detail here. The robot can use the vacuum suction cup to adsorb and fix the material or to release the adsorption and fixation.

[0059] In this embodiment, one robotic arm can be set up, which is used for both feeding and picking up materials. Alternatively, two robotic arms can be set up, with one robotic arm used for feeding materials and the other for picking up materials. Those skilled in the art can set it up according to actual needs, which will not be described in detail here.

[0060] The robotic arm can use existing equipment, which will not be described in detail here. The robotic arm is connected to the control system 18 and can send signals to the control system 18 and receive instructions from the control system to work.

[0061] The detection system in this embodiment eliminates the need for a track and instead uses a robotic arm to place and remove materials from the platform, thus enabling online detection of the materials.

[0062] Example 3 This embodiment provides a method for operating the X-ray detection system described in Embodiment 2: The control system 18 controls the hollow rotary platform 1 to rotate until the first conductive component 4 and the second conductive component 7 come into contact, and the push-pull electromagnet telescopic rod 9 is energized and retracts, releasing the clamping state.

[0063] The robotic arm uses a vacuum suction cup to pick up materials from the previous process and then places the materials on the platform 2. After the robotic arm finishes discharging the materials, it sends a signal to the control system 18. The control system 18 controls the hollow rotary platform 1 to continue rotating. When the first conductive component 4 and the second conductive component 7 separate, the push-pull electromagnet telescopic rod 9 is de-energized and extends, switching to the clamping state to clamp and fix the materials. At this time, the X-ray source 19 and the detector 20 are activated.

[0064] The stage 2 drives the material to rotate, and the X-ray source 19 and detector 20 work together to perform X-ray detection on the material.

[0065] After the test is completed, the hollow rotary platform 1 rotates until the first conductive component 4 and the second conductive component 7 come into contact. The push-pull electromagnet telescopic rod 9 is energized and retracts, and the robot arm takes the tested material off the platform.

[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
