Detailed implementation manners

[0032] To make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the following further details the present application in combination with specific embodiments and with reference to the drawings.

[0033] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of this application should have the ordinary meanings understood by those of ordinary skill in the field to which this application belongs. The "first", "second" and similar terms used in the embodiments of this application do not denote any order, quantity or importance, but are only used to distinguish different components. Words such as "including" or "comprising" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. Words such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0034] Based on the background described above, in the current aerospace field, the reliability screening of electronic components plays a crucial role. This link is directly related to the safety performance and operational stability of aircraft and spacecraft. Among them, the ultrasonic detector, as the core means for detecting internal defects of components, has been widely adopted as the standard method for non-destructive testing. With its high precision and sensitivity to the internal structure of materials, the ultrasonic detector can accurately identify tiny defects inside components, such as cracks, inclusions or pores, etc., thus ensuring that only high-quality components are used in the manufacture of aerospace equipment.

[0035] However, although the ultrasonic detector has significant technical advantages, in the actual application process, its detection process highly depends on manual operation. From the placement and movement of components to the specific detection steps, all need to be completed manually. This highly manual operation mode not only increases the errors that may be brought by human factors, but also makes the automation degree of the entire reliability screening process relatively low. This not only affects the efficiency of the screening work, but also limits the application potential of the ultrasonic detector in larger-scale and more complex environments.

[0036] The following will Figures 1-5 describe the embodiments of this application in detail.

[0037] As Figure 1 , Figure 2 and Figure 3 shown, an automatic component detection device includes:

[0038] A moving station 1 for placing the component and driving the component to move to the position to be operated;

[0039] A spraying assembly 2 provided on one side of the moving station 1 for spraying water mist onto the top surface of the component;

[0040] An ultrasonic detection component 3 is arranged on one side of the moving station 1 and includes an ultrasonic detector 31 and a thin-film container 32 filled with water. The ultrasonic detector 31 includes an ultrasonic detection head 311. The thin-film container 32 is arranged below the ultrasonic detection head 311. The bottom of the thin-film container 32 is a high-transparency film 321. The probe end of the ultrasonic detection head 311 is immersed in water and is opposite to the position of the high-transparency film 321. The moving station 1 drives the component to move below the thin-film container 32 so that the top surface of the component is opposite to the probe end of the ultrasonic detection head 311.

[0041] A lifting component 4 is arranged below the moving station 1 to control the component to rise until the top of the component abuts against the high-transparency film 321 and control the component to reset.

[0042] A drying component 5 is arranged on one side of the moving station 1 to dry the component after detection.

[0043] In addition, an installation platform 6 is further included. The moving station 1, the spraying component 2, the ultrasonic detection component 3 and the lifting component 4 are arranged on the installation platform 6.

[0044] Specifically, the moving station 1 is installed on the installation platform 6. A plurality of installation positions are provided on the moving station 1, and a component is arranged on each installation position. As the moving station 1 moves, the components on different installation positions are simultaneously subjected to different operations by different components to improve the detection efficiency of the components. The ultrasonic detector 31 is a water-immersion ultrasonic detector 31. Therefore, when the ultrasonic detector 31 detects the component, water is required as a coupling agent between the component and the ultrasonic detection head 311. The thin-film container 32 is a water-containing container. The thin-film container 32 is connected to the ultrasonic detector 31 through a bracket. The bottom of the thin-film container 32 is a high-transparency film 321. The high-transparency film 321 can be adhered to the side wall of the thin-film container 32 through a waterproof adhesive to prevent water from seeping out from the side wall between the high-transparency film 321 and the thin-film container 32. The high-transparency film 321 can be a polyethylene film. The polyethylene film has high transparency and certain strength, which is beneficial to the transmission of ultrasonic waves and can bear the water in the thin-film container 32 to ensure the normal detection of the component. The moving station 1 drives the wet component to move below the ultrasonic detector 31, and the lifting component 4 controls the component to rise so that the component abuts against the high-transparency film 321. The high-transparency film 321 flattens the water mist on the top surface of the component to form an ultra-thin water film for the ultrasonic detection head 311 to detect the component. This method of detecting the component separates the component from the ultrasonic detection head 311 through the high-transparency film 321. Without affecting the detection effect of the component, the component is prevented from being directly immersed in water, thereby avoiding the internal defects of the component being filled with water and affecting the detection effect.

[0045] In this embodiment, after placing the component on the moving station 1, the moving station 1 drives the component to rotate under the spraying assembly 2. The spraying assembly 2 sprays water mist on the top surface of the component to wet the top surface of the component. The moving station 1 drives the component to move under the ultrasonic detection head 311. The lifting assembly 4 controls the component to rise so that the component abuts against the high-transparency film 321. The high-transparency film 321 flattens the water mist on the top surface of the component to form an ultra-thin water film, so that the ultrasonic detection head 311 can detect the component. After the ultrasonic detection head 311 finishes detecting the component, the drying assembly 5 dries the component. The above-mentioned component detection device has a high degree of automation, saves manpower, and improves the detection efficiency of the component; in addition, this way of detecting the component separates the component from the ultrasonic detection head 311. Without affecting the detection effect of the component, it avoids the component being directly immersed in water, thereby avoiding the internal defects of the component being filled with water and affecting the detection effect, and improving the detection accuracy of the component.

[0046] In some embodiments, as Figure 1 shown, the moving station 1 is a rotating turntable, and a through slot 11 is provided on the rotating turntable, and the component is arranged in the slot 11.

[0047] Specifically, the components in the circumferential direction of the rotating turntable are evenly distributed along the circumferential direction of the rotating turntable. The slot 11 can be provided with multiple ones according to the number of components and is evenly distributed along the rotating turntable. One component is arranged in each slot 11, so that the components in the circumferential direction of the rotating turntable can operate on different components at the same time, thereby improving the detection efficiency of the components.

[0048] In this embodiment, the slot 11 is used to hold and fix the component, improving the stability of the component during the movement of the moving station 1, preventing the component from shifting in position and causing other components to be unable to align with the component, and thus unable to operate on the component.

[0049] In some embodiments, as Figure 1 and Figure 3 shown, a component automatic detection device further includes a feeding assembly 7. The feeding assembly 7 includes a first slide rail 71, a first slider 72 and a first vacuum suction nozzle 73. The first slide rail 71 is installed on the installation platform 6 and part of the first slide rail 71 is located above the moving station 1. The first slider 72 is slidably connected to the first slide rail 71. The first vacuum suction nozzle 73 is installed on the first slider 72. The first vacuum suction nozzle 73 adsorbs the component and transports it to the slot 11 through the first slider 72 and the first slide rail 71.

[0050] Specifically, the first slide rail 71 is installed on one side of the moving station 1 through a bracket, and a part of the first slide rail 71 is located above the moving station 1, so that the first slider 72 and the first vacuum suction nozzle 73 can move above the moving station 1, so that the first vacuum suction nozzle 73 can accurately place the adsorbed components in the card slot 11 of the moving station 1. A loading tray is also provided on the installation platform 6. The loading tray is located below the first slide rail 71. The loading tray is provided with a plurality of partition chambers, and the partition chambers separate the components to prevent the components from overlapping and affecting the feeding of the feeding assembly 7.

[0051] In this embodiment, the first vacuum suction nozzle 73 realizes the automatic feeding of components through the first slide rail 71 and the first slider 72, saves the manual operation steps, improves the feeding efficiency, and also reduces the error rate caused by improper manual operation. The first vacuum suction nozzle 73 can sequentially adsorb the components on the loading tray, then slide along the first slide rail 71 to above the card slot 11, and the first vacuum suction nozzle 73 releases the components, and the components fall into the card slot 11. Using a vacuum suction nozzle for the adsorption, transportation and release of components has lower energy consumption and higher efficiency, and also reduces the potential damage to the components.

[0052] In some embodiments, such as Figure 1 and Figure 4 shown, the spraying assembly 2 includes a spray head 21, a spray water pipe 22, a pressurized water tank and an air pump. One end of the spray water pipe 22 is connected to the pressurized water tank, and the other end is connected to the spray head 21. The spray head 21 is located above the moving station 1. The moving station 1 drives the component to move below the spray head 21, so that the spray head 21 sprays water mist on the top of the component. The air pump is connected to the spray water pipe 22 to adjust the size of the water mist.

[0053] In addition, a plurality of spray holes 211 are evenly provided on the water spraying end face of the spray head 21 for spraying water mist on the top of the component, and a dripping section 212 is also provided at the central position of the water spraying end face of the spray head 21 for dripping water at the central position of the component.

[0054] Specifically, the pressurized water tank is located on one side of the installation platform 6. The pressurized water tank includes a pressurized pump and a water tank body. The pressurized pump is connected to the water outlet of the water tank body to pump the water in the water tank body into the spray water pipe 22. The spray head 21 is installed on the installation platform 6 through a bracket, and the bracket is telescopic to adjust the height of the spray head 21 to ensure that the water mist can completely cover the top of the component, thereby improving the accuracy of detection.

[0055] In this embodiment, water mist is sprayed onto the top of the component through a pressurized water tank, a water spray pipe 22, and a spray head 21, so that an ultra-thin water film is formed when the top of the component abuts against the high-transparency film 321, ensuring accurate detection of the component by the ultrasonic detection head 311. The water mist sprayed by the above-mentioned spraying assembly 2 is delicate and uniform, and the size of the water mist can be adjusted by an air pump, which is beneficial to forming a uniform ultra-thin water film on the top of the component, facilitating the accurate detection of the component by the ultrasonic detection head 311. A water dripping section 212 is also provided at the central position of the water spraying end face for dripping water onto the central position of the component, improving the efficiency of the spraying assembly 2 in wetting the top surface of the component, thereby improving the overall detection efficiency of the component.

[0056] In some embodiments, as Figure 1 and Figure 3 shown, the lifting assembly 4 is a lift, the lift is installed on the installation platform 6, and after the component moves to below the ultrasonic detection head, the output shaft of the lift penetrates through the card slot 11 to lift the component so that the top surface of the component abuts against the high-transparency film 321.

[0057] Specifically, the card slot 11 includes a square slot and a communication hole. An accommodation slot for placing the component is provided in the square slot, and the top surface of the component protrudes from the accommodation slot. The communication hole is provided at the bottom of the accommodation slot for the output shaft of the lift to pass through. The output shaft of the lift penetrates through the communication hole to lift the accommodation slot and the component. The lift is a hydraulic cylinder. The output of the hydraulic cylinder is stable, ensuring the stability of the component during the rising process, and the hydraulic cylinder can accurately control the rising distance of the component through a control system so that the component just abuts against the high-transparency film 321, ensuring the normal progress of the detection process.

[0058] In this embodiment, by setting a lift on the installation platform 6, the automatic lifting of the component is realized, thereby improving the detection efficiency of the component.

[0059] In some embodiments, as Figure 1 and Figure 3 shown, an automatic component detection device further includes a discharging assembly 8. The discharging assembly 8 includes a second vacuum suction nozzle 81, a second slider 82, and a second slide rail 83. The second slide rail 83 is installed on the installation platform 6 and part of the second slide rail 83 is located above the moving station 1. The second slider 82 is slidably connected to the first slide rail 71. The second vacuum suction nozzle 81 is installed on the second slider 82. A bearing tray 12 is provided on the installation platform 6. The second vacuum suction nozzle 81 adsorbs the component after detection and transports the component to the bearing tray 12 through the second slider 82 and the second slide rail 83.

[0060] Specifically, the second slide rail 83 is installed on one side of the moving station 1 through a bracket, and a part of the second slide rail 83 is located above the moving station 1, so that the second slider 82 and the second vacuum suction nozzle 81 can move above the moving station 1, so that the second vacuum suction nozzle 81 can adsorb the components in the card slot 11 and remove them from the moving station 1. The second vacuum suction nozzle 81 drives the components to move above the receiving tray 12 and releases the components, and the components fall into the receiving tray 12. The feeding assembly 7, the spraying assembly 2, the ultrasonic detection assembly 3 and the discharging assembly 8 are evenly distributed along the circumferential direction of the rotating platform. There are four card slots 11 on the rotating platform, and each card slot 11 is provided with a component, so that the feeding assembly 7, the spraying assembly 2, the ultrasonic detection assembly 3 and the discharging assembly 8 can operate on different components at the same time, thereby improving the detection efficiency of the components.

[0061] In this embodiment, the second vacuum suction nozzle 81 realizes the automatic discharging of components through the second slide rail 83 and the second slider 82, saving manual operation steps and improving the discharging efficiency. The receiving tray 12 is used to collect components for subsequent centralized processing.

[0062] In some embodiments, such as Figure 1 and Figure 3 shown, a third slide rail 13 is provided on the mounting platform 6. The third slide rail 13 is slidably connected to the receiving tray 12 for transporting the receiving tray 12 to the drying assembly 5.

[0063] Specifically, the third slide rail 13 is provided on one side of the moving station 1 and between the moving station 1 and the drying assembly 5. The third slide rail 13 is a linear slide rail and can be driven by a motor. A slider is provided at the bottom of the receiving tray 12, and the slider slides along the linear slide rail to transport the receiving tray 12 to the drying assembly 5.

[0064] In this embodiment, the third slide rail 13 transports the receiving tray 12 to the drying assembly 5, saving manual operation steps and improving the efficiency of transporting the components from one side of the mounting platform 6 to the drying assembly 5.

[0065] In some embodiments, the drying assembly 5 is an oven. The oven is open, and the third slide rail 13 extends into the oven through the opening of the oven, so that the receiving tray 12 can enter the oven.

[0066] Specifically, the oven is provided on one side of the mounting platform 6 and is open. The third slide rail 13 extends into the oven through this opening, so that the receiving tray 12 can enter the oven. The receiving tray 12 is suspended in the oven to improve the drying efficiency of the components in the receiving tray 12.

[0067] In this embodiment, the oven automatically dries the incoming components, saving labor and improving the drying efficiency of the components.

[0068] In some embodiments, such as Figure 2 and Figure 5 shown, the ultrasonic detection component 3 further includes a pulsed laser 33. The pulsed laser 33 is arranged on one side of the ultrasonic detector 31. The pulsed laser 33 emits pulsed laser. A through hole 0311 for the pulsed laser to pass through is provided on the ultrasonic detection head 311. When the ultrasonic detection head 311 is opposite to the position of the component, the ultrasonic detection head 311 emits ultrasonic waves and pulsed laser to the component and receives the ultrasonic waves returned from the component.

[0069] In this embodiment, the ultrasonic detection head 311 on the ultrasonic detector 31 is used to emit ultrasonic waves to the component, and the pulsed laser 33 is used to emit pulsed laser. By providing the through hole 0311 for the pulsed laser to pass through on the ultrasonic detection head 311, the ultrasonic detection head has the function of simultaneously emitting ultrasonic waves and pulsed laser. When the ultrasonic detection head 311 detects the component, the ultrasonic waves emitted by the ultrasonic detection head 311 reach the surface of the component and then return, and are received by the ultrasonic detection head 311 again, so as to obtain the high-precision defect morphology on the surface of the component. The pulsed laser emitted by the ultrasonic detection head 311 excites ultrasonic waves on the surface of the component, and the ultrasonic waves propagate inside the component, reflect when encountering the interface, and are received by the ultrasonic detection head 311 again, so as to obtain the high-precision defect morphology inside the component. Therefore, the ultrasonic detector 31 in this application adopts the method of combining laser ultrasonic and conventional ultrasonic into one, and simultaneously obtains the high-precision defect morphology on the surface of the component and the defect morphology at different depths inside the component through one scan, improving the comprehensiveness of component detection and thus improving the detection efficiency of the component.

[0070] In some embodiments, the ultrasonic detector 31 further includes a base 34. The base 34 is hollow and internally provided with a reflecting lens. The output end of the pulsed laser 33 is connected to a collimator 35 through an optical fiber. The collimator 35 is arranged on one side of the base 34. The output end of the collimator 35 emits pulsed laser to penetrate the base 34 and pass through the through hole 0311 through the reflecting lens.

[0071] In this embodiment, the laser pulser 33 is connected to the collimator 35. The collimator 35 converts the light beam emitted by the pulsed laser 33 into a parallel light beam and focuses the parallel light beam into a pulsed laser beam with a smaller diameter, thereby increasing the energy and effect of the pulsed laser. The base 34 is used to mount the ultrasonic detection head 311. The base 34 is hollow and internally provided with a reflecting lens, which is convenient for adjusting the transmission angle of the pulsed laser so that it accurately passes through the through hole 0311 on the ultrasonic detection head 311, enabling the ultrasonic detection head 311 to simultaneously have the functions of emitting ultrasonic waves and pulsed lasers.

[0072] In some embodiments, a refrigerating sheet is provided on one side of the inner wall of the thin film container 32 to reduce the water temperature.

[0073] In this embodiment, since the pulsed laser can increase the water temperature and affect the propagation of ultrasonic waves, the refrigerating sheet can reduce the water temperature to prevent the increase in water temperature from affecting the transmission of ultrasonic waves, thereby improving the accuracy of internal defect detection of the components.

[0074] In some embodiments, the ultrasonic detection head 311 includes an ultrasonic transducer 3111 and a detection head body 3112. The detection head body 3112 is hollow. The ultrasonic transducer 3111 is installed in the detection head body 3112. The through hole 0311 is provided through the ultrasonic transducer 3111. The ultrasonic transducer 3111 is used to emit ultrasonic waves and receive the ultrasonic waves returned from the component, and convert them into ultrasonic signals.

[0075] In this embodiment, the detection head body 3112 is hollow and used to mount the ultrasonic transducer 3111. The through hole 0311 passes through the ultrasonic transducer 3111 and is in communication with the inside of the detection head body 3112 for the pulsed laser to pass through. The ultrasonic transducer 3111 is the core component of the ultrasonic detection head 311. It can emit ultrasonic waves and pulsed lasers while also receiving the ultrasonic waves from the component and converting them into ultrasonic signals for analyzing the surface and internal defects of the component.
