Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, and in particular to an automatic sorting device for X-ray inspection markers based on dual-mode turntable collaborative operation. Background Technology

[0002] Radiographic markings are non-destructive testing (NDT) techniques used to pinpoint the location of defects in inspected workpieces. Their core function is to achieve radiographic absorption contrast using high-density lead or lead alloys, thereby accurately locating defects on the radiograph. After radiographic testing, the lead markings attached to the surface of the radiograph bag must be peeled off, recycled, and stored in a categorized manner for reuse. Furthermore, these markings must be managed systematically according to size and number to ensure the standardization and traceability of the testing process.

[0003] Currently, the recycling and sorting of X-ray inspection markers mainly relies on manual operation. The specific process includes: operators using tweezers and other tools to peel off the X-ray inspection markers adhering to the dark bag one by one, then visually identifying their numbers or sizes, and finally manually sorting them into the corresponding storage containers according to the classification standards.

[0004] However, manual sorting has the following main problems: each operation requires a lot of time, resulting in low efficiency in the removal and classification of radiographic markers, which is difficult to meet the needs of large-scale testing; at the same time, the repetitive manual operation is intensive, and fatigue can easily lead to misclassification or omission of radiographic markers, reducing management accuracy; in addition, trace amounts of radioactive material may remain on the surface of radiographic markers, and long-term direct contact poses a potential threat to the health of operators. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an automatic sorting device for X-ray inspection markers based on dual-mode turntable cooperative operation, which aims to automatically sort markers with high accuracy and efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic sorting device for X-ray inspection markers based on dual-modal turntable collaborative operation includes a hopper, a tray assembly, a temporary storage box, a self-rotating turntable, an image recognition component, and a sorting component. The hopper has an interconnected feeding section, an inverted conical transition section, and a converging opening from top to bottom. The feeding section extends into a first chute that matches the size of the X-ray inspection markers and is inclined. The tray assembly includes a second chute that slides vertically through the converging opening. The second chute is inclined and its size matches the size of the X-ray inspection markers. The bottom end of the second chute corresponds vertically to the top end of the first chute. The temporary storage box has a sliding channel through which the X-ray inspection markers are stacked sequentially. The top end of the sliding channel corresponds vertically to the bottom end of the first chute. Corresponding to the position, the turntable is provided with closable receiving slots at intervals along the circumference. The receiving slots in the closed state are used to receive X-ray detection markers that slide down from the bottom of the sliding channel. The image recognition component is used to identify the X-ray detection markers in the receiving slots in the closed state. The sorting component includes a control unit and movable sorting boxes of different categories. The control unit is used to sequentially open the receiving slots in the closed state according to the recognition results of the image recognition component, and control the sorting boxes of the corresponding categories to receive the X-ray detection markers that fall from the corresponding receiving slots.

[0007] In addition, the automatic sorting device for X-ray inspection markers based on dual-mode turntable cooperative operation according to the present invention may also have the following additional technical features:

[0008] Furthermore, the bracket assembly also includes a lifting driver, the free end of which is connected to the second slide.

[0009] Furthermore, the lifting driver is an electric actuator.

[0010] Furthermore, a support plate is provided below the turntable to support the X-ray detection marker in the receiving groove. The support plate has a through-hole, and the position of the through-hole corresponds to the rotation path of the receiving groove.

[0011] Furthermore, the image recognition component includes a first image sensor located above the turntable and connected to the control unit.

[0012] Furthermore, the support plate is also provided with a transparent window, which is located on one side of the through opening. The first image sensor is positioned corresponding to the transparent window, and the transparent window is positioned corresponding to the rotation path of the receiving groove. The image recognition component also includes a second image sensor, which is located below the support plate and connected to the control unit. The first image sensor and the second image sensor are arranged vertically opposite each other.

[0013] Furthermore, a weight sensor is provided on the support plate, which is connected to the control unit and is used to obtain the weight of the X-ray detection marker in the sliding channel.

[0014] Furthermore, the automatic sorting device for X-ray inspection markers based on dual-modal turntable collaborative operation also includes a worktable, which is located beside the hopper. The turntable is rotatably mounted on the worktable via a first rotary driver. The temporary storage box and the image recognition component are both located on the worktable.

[0015] Furthermore, the sorting box is rotatably mounted on the worktable by a second rotary driver and is coaxially arranged with the turntable.

[0016] Furthermore, the second chute is provided with a slider, and the side wall of the converging port is provided with a slide rail.

[0017] The beneficial effects of this utility model include at least the following: through the coordinated design of mechanical structures such as hoppers, chutes, and turntables, automatic conveying, temporary storage, and sorting of X-ray inspection markers are achieved, avoiding the tedious process of manual peeling and sorting one by one. Through the linkage between the rotary sorting mechanism of the turntable and the image recognition component, continuous identification and classification of markers can be achieved. At the same time, the position of the sorting box can be dynamically adjusted according to the recognition results of the image recognition component, which can achieve precise matching between markers and storage containers. Compared with traditional manual sorting, both efficiency and classification accuracy can be improved. Attached Figure Description

[0026] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please refer to Figures 1 to 5 The present invention provides an automatic sorting device for X-ray inspection markers based on dual-mode turntable collaborative operation, comprising a hopper 100, a tray assembly 200, a temporary storage box 300, a self-rotating turntable 400, an image recognition component 500, and a sorting component.

[0030] Specifically, the hopper 100 is provided with an interconnected feeding section 110, an inverted conical transition section 120, and a converging port 130 from top to bottom. During operation, the X-ray inspection marker is conveyed into the hopper 100 through the feeding section 110. Under the action of gravity, the X-ray inspection marker tends to flow along the inverted conical transition section 120 to the converging port 130. The feeding section 110 also extends a first chute 111 that matches the size of the X-ray inspection marker and is inclined.

[0031] The tray assembly 200 includes a second chute 210 that slides vertically through the converging opening 130. The width of the second chute 210 matches the size of the X-ray inspection marker, ensuring that multiple X-ray inspection markers cannot be supported side-by-side along its width. Simultaneously, the depth of the second chute 210 matches the size of the X-ray inspection marker, ensuring that multiple X-ray inspection markers cannot be stacked along its depth. To allow the X-ray inspection markers within the second chute 210 to be sequentially conveyed along its length, the second chute 210 is also inclined, allowing them to slide sequentially down to the bottom of the second chute 210 under gravity. To ensure that the first chute 111 smoothly receives the X-ray inspection markers sliding out from the bottom of the second chute 210, the bottom of the second chute 210 and the top of the first chute 111 must be vertically aligned. It is understandable that when the first chute 111 receives the X-ray inspection marker that slides out from the bottom of the second chute 210, the bottom of the second chute 210 and the top of the first chute 111 can be spaced apart or connected together, as long as the X-ray inspection marker does not slip out of the chute.

[0032] The temporary storage box 300 is provided with a sliding channel 310 through which X-ray inspection markers are stacked sequentially. In order for the sliding channel 310 to smoothly receive the X-ray inspection markers sliding out from the bottom end of the first chute 111, the top end of the sliding channel 310 and the bottom end of the first chute 111 need to be vertically aligned. It can be understood that when the sliding channel 310 receives the X-ray inspection markers sliding out from the bottom end of the first chute 111, the bottom end of the first chute 111 and the top end of the sliding channel 310 can be spaced apart or connected, as long as the sliding X-ray inspection markers do not deviate outside the chute or the sliding channel 310.

[0033] The turntable 400 is provided with closable receiving slots 410 spaced circumferentially. When the receiving slots 410 are closed, they can receive X-ray detection markers that slide out from the bottom of the sliding channel 310. The image recognition component 500 is used to identify the X-ray detection markers in the closed receiving slots 410. It can be understood that multiple sets of image recognition components 500 can be set up to simultaneously identify X-ray detection markers in multiple receiving slots 410. Alternatively, a single set of image recognition components 500 can be set up to sequentially identify X-ray detection markers in receiving slots 410 that approach the image recognition component 500.

[0034] The sorting assembly includes a control unit (not shown in the figures) and movable sorting boxes 610 for different categories. The control unit is used to sequentially open the closed receiving slots 410 according to the recognition results of the image recognition component 500. It should be noted that "sequentially" here refers to opening the closed receiving slots 410 in the order of rotation of the turntable 400 or the reverse direction of rotation of the turntable 400, according to their arrangement. At the same time, it controls the sorting box 610 of the corresponding category to move under the corresponding receiving slot 410 to receive the X-ray detection markers of the corresponding category that fall. Optionally, the control unit can be selected from automatic control devices such as PLC (Programmable Logic Controller), MCU control module, FPGA control module, and DSP control module.

[0035] In some alternative embodiments, such as Figure 2 As shown, the tray assembly 200 also includes a lifting driver 220, the free end of which is connected to the second chute 210. When the lifting driver 220 is in operation, its free end drives the second chute 210 to reciprocate up and down through the converging opening 130. When the top of the second chute 210 extends upward through the converging opening 130, the X-ray detection markers accumulated in the converging opening 130 can be supported within the opening of the second chute 210. Preferably, the lifting driver 220 is an electric actuator, the fixed end of which can be fixed to the hopper 100 or separately fixed at the work site.

[0036] In some alternative embodiments, such as Figure 1 , Figure 3As shown, a support plate 700 for supporting the X-ray inspection markers in the receiving slot 410 is provided below the turntable 400. The support plate 700 has a through-hole 710, which corresponds to the position of the rotation path of the receiving slot 410. When the rotating turntable 400 moves the receiving slot 410 to a position corresponding to the vertical position of the through-hole 710, the X-ray inspection markers in the receiving slot 410 can fall out. At this time, the control unit only needs to control the corresponding category classification box 610 to move under the through-hole 710 according to the type of X-ray inspection marker in the receiving slot 410, so as to catch the falling X-ray inspection marker of the corresponding category. It is understandable that the support plate 700 can be spaced apart from the turntable 400, but to ensure that the X-ray inspection marker in the receiving groove 410 does not escape from between the support plate 700 and the turntable 400, the support plate 700 can also be fitted to the turntable 400. In this case, in order to reduce the friction between the two, the upper surface of the support plate 700 can be made into a smooth surface, or the upper surface of the turntable 400 can be made into a smooth surface.

[0037] In some alternative embodiments, such as Figure 1 , Figure 3 , Figure 4 As shown, the image recognition component 500 includes a first image sensor 510, which is located above the turntable 400 and connected to the control unit. The first image sensor 510 acquires images of the X-ray detection markers within the receiving slot 410 and transmits them to the control unit. The control unit analyzes the images using an image processing algorithm and then classifies them. It should be noted that the image processing algorithm used here is existing technology and will not be described in detail.

[0038] In some optional embodiments, to improve image recognition performance, such as Figure 4 As shown, the support plate 700 also has a transparent window 720, which is located on one side of the through opening 710. Optionally, the transparent window 720 can be made of materials such as acrylic sheet or glass. The first image sensor 510 corresponds to the position of the transparent window 720, and the transparent window 720 corresponds to the position of the rotation path of the receiving groove 410. When the rotating turntable 400 moves the receiving groove 410 to a position corresponding to the upper and lower positions of the transparent window, the X-ray detection marker in the receiving groove 410 can be supported by the transparent window 720. Figure 3 , Figure 5As shown, the image recognition component 500 also includes a second image sensor 520, which is located below the support plate 700 and connected to the control unit. The first image sensor 510 and the second image sensor 520 are arranged vertically opposite each other. In this case, the second image sensor 520 can acquire an image of the underside of the X-ray detection marker through the transparent window 720. It is understood that, in order to obtain a clear, high-contrast image, illumination lights can be provided on the first image sensor 510 and / or the second image sensor 520.

[0039] In this embodiment, the first image sensor 510 and the second image sensor 520 respectively acquire images of the X-ray detection marker in the receiving slot 410 from different angles and transmit them to the control unit. The control unit analyzes the images according to the image processing algorithm and then classifies them, which can improve the recognition and classification accuracy.

[0040] In some optional embodiments, a weight sensor is provided on the support plate 700. The weight sensor is connected to the control unit, which acquires the weight of the X-ray inspection markers in the sliding channel 310 collected by the weight sensor, and controls the feeding rhythm based on the number of X-ray inspection markers in the sliding channel 310. For example, the weight sensor is a pressure sensor with two thresholds: a medium-speed feeding threshold and a stop feeding threshold. When the value acquired by the pressure sensor exceeds the medium-speed feeding threshold, it indicates that the number of X-ray inspection markers in the sliding channel 310 is too large. At this time, the control unit can control the electric push rod to reduce the pushing frequency, thereby reducing the feeding speed of the second chute 210. When the value acquired by the pressure sensor exceeds the stop feeding threshold, it indicates that the number of X-ray inspection markers in the sliding channel 310 is too large. At this time, the control unit controls the electric push rod to stop working. This setting ensures that the number of markers in the sliding channel 310 is within a reasonable range, avoiding structural blockage due to excessive quantity, which could lead to abnormalities in the sorting process.

[0041] In some alternative embodiments, such as Figures 1 to 5 As shown, the automatic sorting device for X-ray inspection markers based on dual-modal turntable collaborative operation also includes a worktable 800, which is located beside the hopper 100. The turntable 400 is rotatably mounted on the worktable 800 via a first rotary driver (not shown in the figures). The temporary storage box 300 and the image recognition component 500 are both located on the worktable 800. Optionally, the first rotary driver can be a rotary motor, a rotary cylinder, a rotary hydraulic cylinder, or other power device.

[0042] In some alternative embodiments, such as Figure 5As shown, the sorting box 610 is formed by dividing a circular box body 620 along the axial direction. The circular box body 620 is rotatably mounted on the worktable 800 by a second rotary actuator (not shown in the figure), and the circular box body 620 is coaxially arranged with the turntable 400. By rotating the second rotary actuator, the corresponding sorting box 610 is rotated to below the through-hole 710, thereby receiving the X-ray detection marker of the corresponding category. Optionally, the second rotary actuator can be a power device such as a rotary motor, a rotary cylinder, or a rotary hydraulic cylinder.

[0043] In some optional embodiments, in order to enable the second slide groove 210 to slide smoothly through the converging port 130, a slider is provided on the second slide groove 210 and a slide rail is provided on the side wall of the converging port 130. Through the cooperation of the slider and the slide rail, a stable sliding between the second slide groove 210 and the converging port 130 is achieved.
