Description

Technical Field

[0001] The present application relates to the technical field of container detection, and in particular to a multi-directional detection device for a container body. Background Art

[0002] During the container inspection process, inspectors need to check the integrity of the container, which is crucial to the safety and smooth operation of transportation. Therefore, the importance of container inspection is becoming increasingly prominent. In recent years, with the innovation of inspection equipment and the development of artificial intelligence (AI) technology, automated container inspection has gradually replaced manual inspection. The implementation of AI container inspection can not only significantly improve container inspection efficiency and save labor costs, but also improve the stability of container inspection quality and reduce communication costs between parties involved in equipment handover.

[0003] However, existing inspection methods cannot match the appropriate distance to scan the front panel, top panel and door of the container, and container inspectors are required to climb to the top of the container for inspection. Manual climbing to the top of the container for inspection takes a long time, affecting the overall inspection efficiency, especially when a large number of containers need to be inspected. Utility Model Content

[0004] In view of this, the main purpose of this application is to provide a multi-directional detection device for container bodies, which is conducive to solving the problem that the existing inspection method cannot match the appropriate distance to scan the container, resulting in low efficiency of the entire inspection box.

[0005] The present application provides a multi-directional detection device for a container body, comprising:

[0006] The three-stage telescopic mechanism is located above the container body. The three-stage telescopic mechanism includes a first telescopic part, a second telescopic part and a third telescopic part arranged in parallel with each other.

[0007] The first telescopic part includes a first linear rail and a first electric cylinder. The side end of the first linear rail is fixedly connected to the electric cylinder body of the first electric cylinder.

[0008] The second telescopic part includes a second linear rail and a second electric cylinder. The bottom end of the second linear rail is fixedly connected to the push rod end of the first electric cylinder, the top end of the second linear rail is fixedly connected to the push rod end of the second electric cylinder, and the second linear rail is slidably connected to the first linear rail.

[0009] A third telescopic portion includes a third linear rail, a side end of the third linear rail is fixedly connected to the electric cylinder body of the second electric cylinder, and the third linear rail is slidably connected to the second linear rail;

[0010] The flipping mechanism is arranged at the bottom end of the three-stage telescopic mechanism. A plurality of cameras are arranged on the side of the flipping mechanism facing the container body, and the cameras are flipped at an angle under the action of the flipping mechanism.

[0011] As shown above, the telescopic mechanism is extended and retracted through the cooperation of two electric cylinders and three linear rails, which is more flexible. The position of the camera at the lower end of the three-stage telescopic mechanism can be adjusted according to the different heights of the container (such as the front plate, top plate, and door), thereby covering more detection points and improving the comprehensiveness of the detection. The design of the three-stage telescopic mechanism allows the camera to automatically extend and retract to the appropriate distance to adapt to the detection needs of containers of different sizes and positions. Through multi-stage telescopic adjustment, it can be quickly adjusted to the ideal detection position, which improves detection efficiency, reduces the demand for manpower, and reduces operating costs. With the help of the flipping mechanism, the camera can capture images of the container from different angles. These images are used to detect defects on the container body, such as cracks, dents, protrusions, holes, etc. This design makes image acquisition more accurate and helps to improve the accuracy of defect identification.

[0012] Optionally, the second linear rail is slidably connected to the first linear rail, and further includes: a first slider fixing plate is fixedly connected to the side end of the second linear rail, and the first slider fixing plate is fixedly connected to the first slider of the first linear rail.

[0013] As described above, the first slider fixing plate increases the structural strength and can better support the second linear rail under heavy load conditions to prevent deformation or offset during the extension and retraction process.

[0014] Optionally, the third linear rail is slidably connected to the second linear rail, and further includes: a second slider fixing plate is fixedly connected to the side end of the third linear rail, and the second slider fixing plate is fixedly connected to the second slider of the second linear rail.

[0015] As described above, the connection between the second slider fixing plate and the second slider can increase the stability of the connection between the third linear rail and the second linear rail, avoiding shaking or deviation from the predetermined track during the extension and retraction process.

[0016] Optionally, the flipping mechanism includes: a fixed beam, with reinforcing connecting plates provided on both sides of the middle position, the reinforcing connecting plates are fixedly connected to the lower end of the third linear rail, a double-output shaft motor is provided on the bottom side of the middle position of the fixed beam, and anti-collision parts are provided at both ends of the fixed beam; two rotating shafts, one end of which is provided on the bearing seats at both ends of the bottom side of the fixed beam and is parallel to the fixed beam, the other ends of the two rotating shafts are respectively connected to the two ends of the double-output shaft motor through a reducing coupling, flanges are provided at both ends of the rotating shaft, the flanges are fixed to the camera, and a photoelectric switch and a positioning plate are provided on the rotating shaft for positioning the rotation angle of the rotating shaft.

[0017] As shown above, by adjusting the angle of the camera through the flipping mechanism, it is possible to detect containers at different angles, ensuring comprehensive and detailed detection, and facilitating the discovery of subtle damage on the container surface, such as cracks, dents, etc.; the middle position of the fixed beam is fixedly connected to the lower end of the three-stage telescopic mechanism through a reinforcing connecting piece, which enhances the stability of the system and prevents the equipment from shaking or deviating during the flipping process; the output shafts at both ends of the motor are connected to the rotating shaft through a reducing coupling, which can stably drive the rotating shaft to rotate, ensuring the smoothness and controllability of the flipping action; the anti-collision part can prevent the camera from colliding with the container body; the rotating shaft in the flipping mechanism is provided with a photoelectric switch and a positioning plate. The combination of the two can accurately control the rotation angle of the rotating shaft, so that the flipping mechanism can quickly and accurately position to the required angle, thereby improving the detection efficiency.

[0018] Optionally, the anti-collision part includes: an anti-collision bracket, which is L-shaped, and the bottom end of the L is arranged toward the side of the fixed beam where the camera is installed.

[0019] As shown above, the design of the anti-collision bracket can effectively prevent the camera from colliding with the container during the flipping process, and the L-shaped design can effectively utilize limited space.

[0020] Optionally, the anti-collision part includes: a through-beam photoelectric sensor, which is arranged on the anti-collision bracket.

[0021] As shown above, a through-beam photoelectric sensor is also fixedly installed on the anti-collision bracket, which can monitor the distance between the camera and the container in real time to avoid collision.

[0022] Optionally, a motor fixing plate is installed on the bottom side of the middle position of the fixed beam, and the lower end of the motor fixing plate is fixedly connected to the double-output shaft motor.

[0023] From above, the motor fixing plate is installed on the bottom side of the middle position of the fixed beam, and the fixed beam is used as a supporting structure to ensure that the dual-output shaft motor is firmly installed and not prone to loosening or displacement, thereby improving the structural stability of the entire flip mechanism.

[0024] Optionally, the bottom end of the second linear rail is fixedly connected to the push rod end of the first electric cylinder, and also includes: the bottom end of the second linear rail is fixedly connected to one side of the upper surface of the second lower end plate; the push rod end of the first electric cylinder is fixedly connected to the other side of the upper surface of the second lower end plate.

[0025] From above, the push rod end of the first electric cylinder is set downward, and the push rod end of the first electric cylinder and the bottom end of the second linear rail are both set on the upper surface of the second lower end plate. This makes the connection between the second linear rail and the first electric cylinder more stable, and reduces the shaking or deformation caused by single-point force during the extension and retraction process.

[0026] Optionally, the top end of the second linear rail is fixedly connected to the push rod end of the second electric cylinder, and also includes: the top end of the second linear rail is fixedly connected to one side of the lower surface of the second upper end plate; the push rod end of the second electric cylinder is fixedly connected to the other side of the lower surface of the second upper end plate.

[0027] From above, the push rod end of the second electric cylinder is set upward, and the push rod end of the second electric cylinder and the top end of the second linear rail are both set on the lower surface of the second lower end plate. Since the second electric cylinder is fixedly connected to the third linear rail, when the push rod of the second electric cylinder is pushed out, the cylinder body of the second electric cylinder will drive the third linear rail to slide downward along the second linear rail.

[0028] Optionally, the second lower end plate and the second upper end plate are configured to be L-shaped.

[0029] As described above, the L-shaped structure enables the two ends of the second linear rail to be fixedly connected to one end of the first electric cylinder and one end of the second electric cylinder respectively.

[0030] In summary, the multi-directional container inspection device provided in this application primarily comprises a three-stage telescopic mechanism and a tilting mechanism. The advantages of the three-stage telescopic mechanism lie in its compact and rational structure, its ability to automatically adapt to the inspection process for containers of varying sizes, its smooth operation, and its excellent inspection results. This mechanism can be more consistently identified by image acquisition equipment, thus improving the device's reliability. It can reliably detect defects such as cracks, dents, protrusions, holes, container number identification, and missing parts, ensuring the container's pass rate. This inspection covers both 20-foot and 40-foot container trucks, and both high-cube and low-cube container trucks. The three-stage telescopic mechanism can detect the front panel, top panel and door respectively according to the height of different boxes, thereby saving detection time; the three-stage telescopic mechanism can be extended and retracted in the vertical direction to adjust the appropriate height, and the flip mechanism drives the camera to rotate, so that the camera can capture images at different angles; through the design of the three-stage telescopic mechanism, the device can quickly, efficiently and stably complete the purpose of replacing manual work, and at the same time can more accurately detect container boxes. The camera shooting makes the image clearer and clearer, and the image data more accurate, making the collected image convenient for detection algorithm analysis. BRIEF DESCRIPTION OF THE DRAWINGS

The specific embodiments described below can be combined with each other to form new embodiments. The same or similar ideas or processes described in one embodiment may not be repeated in other embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0044] Figure 1 The fully extended structure of a multi-directional detection device for a container body in this application is shown. The multi-directional detection device for a container body includes:

[0045] The three-stage telescopic mechanism 2 is located above the container body. The three-stage telescopic mechanism 2 includes a first telescopic portion 201, a second telescopic portion 202 and a third telescopic portion 203 arranged in parallel with each other.

[0046] The first telescopic part 201 includes a first linear rail 2011 and a first electric cylinder 2012. The side end of the first linear rail 2011 is fixedly connected to the electric cylinder body of the first electric cylinder 2012.

[0047] The second telescopic part 202 includes a second linear rail 2021 and a second electric cylinder 2022. The bottom end of the second linear rail 2021 is fixedly connected to the push rod end of the first electric cylinder 2012, and the top end of the second linear rail 2021 is fixedly connected to the push rod end of the second electric cylinder 2022. The second linear rail 2021 is slidably connected to the first linear rail 2011.

[0048] The third telescopic portion 203 includes a third linear rail 2031 , the side end of which is fixedly connected to the electric cylinder body of the second electric cylinder 2022 , and the third linear rail 2031 is slidably connected to the second linear rail 2021 ;

[0049] The flipping mechanism 3 is arranged at the bottom end of the three-stage telescopic mechanism 2 . A plurality of cameras 308 are arranged on the side of the flipping mechanism 3 facing the container body, and the cameras 308 are flipped at different angles under the action of the flipping mechanism 3 .

[0050] Specifically, the telescopic mechanism 2 is extended and retracted by the cooperation of two electric cylinders and three linear rails, which is more flexible. The position of the camera 308 at the lower end of the three-stage telescopic mechanism 2 can be adjusted according to the different heights of the container (such as the front plate, top plate, and door), thereby covering more detection points and improving the comprehensiveness of the detection. The design of the three-stage telescopic mechanism 2 allows the camera 308 to automatically extend and retract to the appropriate distance to meet the detection needs of containers of different sizes and positions. Through multi-stage telescopic adjustment, it can be quickly adjusted to the ideal detection position, which improves detection efficiency, reduces the demand for manpower, and reduces operating costs. With the help of the flipping mechanism 3, the camera 308 can capture images of the container from different angles. These images are used to detect defects on the container body, such as cracks, dents, protrusions, holes, etc. This design makes image acquisition more accurate and helps to improve the accuracy of defect identification.

[0051] It should be noted that, in order to ensure that the three-stage telescopic mechanism 2 is located above the container body, a column steel mechanism is provided on one side of the container truck, and a cantilever steel mechanism 1 (such as Figure 3-4 shown), now Figure 4The direction shown is the front, and the side equipped with the three-stage telescopic mechanism 2 is the left. In the cantilever steel mechanism 1, cantilevers are respectively provided on the left and right sides of the column, namely the left cantilever and the right cantilever. The left cantilever and the right cantilever both form a stable triangular structure with the column through inclined pillars. Since there is a load on the left cantilever (the three-stage telescopic mechanism 2 and the flipping mechanism 3), in order to maintain the stability of the left cantilever, pillars are provided on the upper and lower sides of the left cantilever to form two stable triangular structures. When the three-stage telescopic mechanism 2 is extended and retracted in the vertical direction to adjust the appropriate height to adapt to the distance of the container body, the left cantilever remains stable.

[0052] In an optional embodiment of the present application, the second linear rail 2021 is slidably connected to the first linear rail 2011, and further includes: a first slider fixing plate 2023 is fixedly connected to the side end of the second linear rail 2021, and the first slider fixing plate 2023 is fixedly connected to the first slider 2011b of the first linear rail 2011.

[0053] Specifically, the first slider fixing plate 2023 increases the structural strength and can better support the second linear rail 2021 under heavy load conditions to prevent deformation or displacement during the extension and retraction process.

[0054] In the above embodiment, the third linear rail 2031 is slidably connected to the second linear rail 2021, and further includes: a second slider fixing plate 2032 is fixedly connected to the side end of the third linear rail 2031, and the second slider fixing plate 2032 is fixedly connected to the second slider 2021b of the second linear rail 2021.

[0055] Specifically, the connection between the second slider fixing plate 2032 and the second slider 2021b can increase the stability of the connection between the third linear rail 2031 and the second linear rail 2021, thereby avoiding shaking or deviation from the predetermined track during the extension and retraction process.

[0056] In an optional embodiment of the present application, the bottom end of the second linear rail 2021 is fixedly connected to the push rod end of the first electric cylinder 2012, and also includes: the bottom end of the second linear rail 2021 is fixedly connected to one side of the upper surface of the second lower end plate 2024; the push rod end of the first electric cylinder 2012 is fixedly connected to the other side of the upper surface of the second lower end plate 2024.

[0057] Specifically, the push rod end of the first electric cylinder 2012 is set downward, and the push rod end of the first electric cylinder 2012 and the bottom end of the second linear rail 2021 are both set on the upper surface of the second lower end plate 2024. This makes the connection between the second linear rail 2021 and the first electric cylinder 2012 more stable, reducing the shaking or deformation problem caused by single-point force during the extension and retraction process.

[0058] In the above embodiment, the top end of the second linear rail 2021 is fixedly connected to the push rod end of the second electric cylinder 2022, and also includes: the top end of the second linear rail 2021 is fixedly connected to one side of the lower surface of the second upper end plate 2025; the push rod end of the second electric cylinder 2022 is fixedly connected to the other side of the lower surface of the second upper end plate 2025.

[0059] Specifically, the push rod end of the second electric cylinder 2022 is set upward, and the push rod end of the second electric cylinder 2022 and the top end of the second linear rail 2021 are both set on the lower surface of the second lower end plate 2024. Since the second electric cylinder 2022 is fixedly connected to the third linear rail 2031, when the push rod of the second electric cylinder 2022 is pushed out, the cylinder body of the second electric cylinder 2022 drives the third linear rail 2031 to slide downward along the second linear rail 2021.

[0060] In the above embodiment, the second lower end plate 2024 and the second upper end plate 2025 are configured to be L-shaped.

[0061] Specifically, the L-shaped structure enables two ends of the second linear rail 2021 to be fixedly connected to one end of the first electric cylinder 2012 and one end of the second electric cylinder 2022 respectively.

[0062] In such Figure 1 In the embodiment shown, with the direction in which the camera 308 faces the container as the front, the front sides of the first linear rail 2011, the second linear rail 2021 and the third linear rail 2031 are provided with a drag chain 204, i.e., an inverted S-shaped channel, for accommodating cables that support the movement of the electric cylinder, such as signal cables and power cables. The first linear rail 2011, the second linear rail 2021 and the third linear rail 2031 are arranged side by side and are all made of aluminum profiles. The three are connected by a first slider fixing plate 2023 and a second slider fixing plate 2032. The first linear rail 2011 is composed of a first guide rail 2011a and a first slider 2011b, the second linear rail 2021 is composed of a second guide rail 2021a and a second slider 2021b, and the third linear rail 2031 is composed of a third guide rail. A lifting fixing plate is provided on the left side of the first linear rail 2011, which is fixed to the cantilever steel mechanism 1 located on the left side of the three-section telescopic mechanism 2 through the lifting fixing plate (as shown in FIG. Figure 3-4As shown, a first slider fixing plate 2023 is fixedly connected to the first slider 2011b on the right side of the first linear rail 2011, and the first slider fixing plate 2023 is fixedly connected to the second linear rail 2021. The front side of the first linear rail 2011 is arranged in parallel with the first electric cylinder 2012, and the cylinder body of the first electric cylinder 2012 is fixed on the first linear rail 2011 and can be fixed by a flat plate with a threaded hole. The push rod end of the first electric cylinder 2012 is set downward, and the push rod end of the first electric cylinder 2012 is fixedly connected to the lower end of the second linear rail 2021 through the second lower end plate 2024. The upper end of the second linear rail 2021 is connected to the second electric cylinder 20 The push rod end of 22 is fixedly connected through the second upper end plate 2025, and the push rod end of the second electric cylinder 2022 is set upward, the cylinder body of the second electric cylinder 2022 is fixedly set on the front side of the third linear rail 2031, and the third linear rail 2031 is slidably connected to the second slider 2021b on the right side of the second linear rail 2021 through the second slider fixing plate 2032. Since the first linear rail 2011, the second linear rail 2021 and the third linear rail 2031 are in the same row, and the first electric cylinder 2012 and the second electric cylinder 2022 are in the front row of the three, the second upper end plate 2025 and the second lower end plate 2024 are set to be right-angled or L-shaped. When the push rod of the first electric cylinder 2012 is pushed downward, the second linear rail 2021 slides downward along the first linear rail 2011 driven by the first electric cylinder 2012, and at the same time the third linear rail 2031 and the second electric cylinder 2022 slide together with the second linear rail 2021; when the push rod of the second electric cylinder 2022 is pushed upward, the third linear rail 2031 slides downward along the second linear rail 2021, thus completing the secondary extension and achieving three height sections.

[0063] In addition, the three-stage telescopic mechanism 2 can be set in a rectangular cover box with an opening at the lower end to facilitate the telescopic movement of the first telescopic part 201, the second telescopic part 202 and the third telescopic part 203 in the vertical direction.

[0065] Specifically, by adjusting the angle of the camera 308 through the flipping mechanism 3, it is possible to detect different angles of the container, ensuring comprehensiveness and meticulousness of the detection, and facilitating the discovery of subtle damage to the surface of the container, such as cracks, dents, etc.; the middle position of the fixed beam 301 is fixedly connected to the lower end of the three-stage telescopic mechanism 2 by a reinforcing connecting piece 3011, which enhances the stability of the system and prevents the equipment from shaking or deviating during the flipping process; the output shafts at both ends of the motor are connected to the rotating shaft 304 through a reducing coupling 306, which can stably drive the rotating shaft 304 to rotate, ensuring the smoothness and controllability of the flipping action; the anti-collision part 303 can prevent the camera 308 from colliding with the container body; the rotating shaft 304 in the flipping mechanism 3 is provided with a photoelectric switch 309 and a positioning plate 310. The combined use of the two can accurately control the rotation angle of the rotating shaft 304, so that the flipping mechanism 3 can quickly and accurately position to the required angle, thereby improving the detection efficiency.

[0066] In the above embodiment, the anti-collision portion 303 includes: an anti-collision bracket 3031 , which is L-shaped, with the bottom end of the L-shaped bracket facing the side of the fixed beam 301 where the camera 308 is installed.

[0067] Specifically, the design of the anti-collision bracket 3031 can effectively prevent the camera 308 from colliding with the container during the flipping process, and the L-shaped design can effectively utilize limited space.

[0068] In the above embodiment, the anti-collision portion 303 includes a through-beam photoelectric sensor 3032 , which is disposed on the anti-collision bracket 3031 .

[0069] Specifically, a through-beam photoelectric sensor 3032 is fixedly installed on the anti-collision bracket 3031, which can monitor the distance between the camera 308 and the container in real time to avoid collision.

[0070] In an optional embodiment of the present application, a motor fixing plate 3012 is installed on the bottom side of the middle position of the fixed beam 301 , and the lower end of the motor fixing plate 3012 is fixedly connected to the dual-output shaft motor 302 .

[0071] Specifically, the motor fixing plate 3012 is installed on the bottom side of the middle position of the fixed beam 301, and the fixed beam 301 is used as a supporting structure to ensure that the dual-output shaft motor 302 is firmly installed and not prone to loosening or displacement, thereby improving the structural stability of the entire flip mechanism 3.

[0072] In this embodiment, the anti-collision part 303 can be provided with only an L-shaped anti-collision bracket 3031, and the bottom end of the L-shape extends out of the bottom end of the camera 308, so that the container cannot collide with the camera 308; it can also be provided with an L-shaped anti-collision bracket 3031 and a through-beam photoelectric sensor 3032, and the through-beam photoelectric sensor 3032 is used to detect the distance to the container in real time. When the distance is too small, the three-stage telescopic mechanism 2 and the flipping mechanism 3 are adjusted in time to prevent collision.

[0073] In such Figure 2 In the illustrated embodiment, the flipping mechanism 3 includes a fixed beam 301, and reinforcing connecting plates 3011 are installed on the sides of both sides of the middle of the fixed beam 301. The reinforcing connecting plates 3011 are fixedly installed on both sides of the lower end of the third linear rail 2031. A motor fixing plate 3012 is installed at the bottom of the fixed beam 301, and a dual-output shaft motor 302 is installed at the lower end of the motor fixing plate 3012. The output shaft ends on both sides of the dual-output shaft motor 302 are installed with reducing couplings 306. The reducing coupling 306 is installed with a rotating shaft 304. The rotating shaft 304 is fixed on the bearing seat 305 at the same axis end. The bearing seat 305 is located below the bottom of both sides of the fixed beam 301. Flanges 307 are installed at both ends of the rotating shaft 304, and the flanges 307 are fixed to the camera 308 (3D camera 308). A photoelectric switch 309 and a positioning plate 310 are also installed on the rotating shaft 304, which can locate the angle of the rotating shaft 304. Anti-collision brackets 3031 are installed on both end surfaces of the fixed beam 301. The anti-collision bracket 3031 is L-shaped. A through-beam photoelectric sensor 3032 (which can be simply referred to as through-beam photoelectric) is fixedly installed on the anti-collision bracket 3031 to prevent the 3D camera 308 from colliding with the box.

[0074] In summary, the multi-directional container inspection device provided in this application primarily comprises a three-stage telescopic mechanism 2 and a tilting mechanism 3.

This mechanism can be more consistently identified by image acquisition equipment, thus improving the device's reliability. It can reliably detect defects such as cracks, dents, protrusions, holes, container number identification, and missing parts, ensuring the container's pass rate. This inspection covers both 20-foot and 40-foot container trucks, and both high-cube and low-cube container trucks. The three-stage telescopic mechanism 2 can detect the front plate, top plate and door respectively according to the height of different boxes, thereby saving detection time; the three-stage telescopic mechanism 2 is telescoped in the vertical direction to adjust the appropriate height, and the flip mechanism 3 drives the camera 308 to rotate, so that the camera 308 can collect images at different angles; through the design of the three-stage telescopic mechanism 2, the device can quickly, efficiently and stably complete the purpose of replacing manual work, and at the same time can more accurately detect the container box. The shooting of the camera 308 makes the image clearer and clearer, and the image data is more accurate, so that the collected image is convenient for detection algorithm analysis.
