Specific implementation
[0020] The specific implementation of the utility model is described in further detail below in combination with the drawings and embodiments. The following embodiments are used to illustrate the utility model, but not to limit the scope of the utility model.
[0021] As Figure 1 And Figure 2 The utility model provides a kind of air cargo plate airworthiness inspection device, including rotating assembly 1, the fixed frame for being connected with support, support 2, multiple scanning assemblies 3 and control unit, rotating assembly 1, scanning assembly 3 respectively with control unit electric connection, support 2 includes first support rod 21 and connecting rod 22, first support rod 21 is connected with connecting rod 22, and first support rod 21 and connecting rod 22 are formed with first included angle between, scanning assembly 3 is installed on connecting rod 22, rotating assembly 1 is connected with first support rod 21, to drive first support rod 21 around goods rotation, support 2 is connected with fixed frame.
[0022] The embodiment makes scanning assembly 3 can rotate around the measured object (such as air cargo plate) by rotating assembly 1, and rotates according to preset angle or speed by electric connection with control unit, to ensure that scanning assembly 3 can cover the object to be inspected from different angles, can obtain more 3D data at a time, reduces the demand of multiple independent 3D image splicing, to reduce error, greatly shorten the time required for single inspection, meet the demand of modern air logistics rapid turnover.
[0023] It can be understood that the fixing frame of the embodiment is used to stably mount the entire inspection device on a support such as the ground or a workbench. It provides a stable foundation, ensuring that the equipment will not be displaced during scanning due to external interference, thereby improving the reliability of the measurement results.
[0024] Further, the connecting rod 22 comprises a first rod member 221 and a second rod member 222, the second rod member 222 is connected with the first support rod 21 through the first rod member 221, a first included angle is formed between the first rod member 221 and the first support rod 21, a second included angle is formed between the second rod member 222 and the first rod member 221, and the first rod member 221 and the second rod member 222 are both provided with the scanning assembly 3.
[0025] The first included angle formed between the first support rod 21 and the first rod member 221 and the second included angle between the first rod member 221 and the second rod member 222 can achieve a wider angle of view coverage, and the multi-angle arrangement allows the scanning assembly 3 to approach the measured object from multiple directions, thereby obtaining more comprehensive data. In addition, since the first rod member 221 and the second rod member 222 can independently adjust their angles relative to each other, the entire device can flexibly cope with goods of various sizes and shapes, ensuring effective measurement regardless of how the goods are placed.
[0026] Further, the first included angle is 130-140°, which is an obtuse angle, so that the first rod member 221 is spread outward relative to the first support rod 21, thereby increasing the spatial range that the scanning assembly 3 can reach. Such an arrangement helps to cover a larger vertical height, ensuring that the goods on higher positions can be scanned, allowing the entire device to be more compactly arranged in limited space while maintaining sufficient operational flexibility, without occupying too much working area due to excessive stretching. In addition, a larger opening angle reduces the possibility of occlusion or dead angles during scanning, improving the integrity of data collection. Preferably, the first included angle is 135°.
[0027] Further, the second included angle is 130-140°, which is an obtuse angle, which can expand the coverage of the scanning assembly 3 in the horizontal direction. This is particularly important for handling goods with a larger width or irregular shape, as it allows scanning from more different sides. Preferably, the second included angle is 135°.
[0028] Further, the length ratio of the first rod 221 and the second rod 222 is 0.75-0.85. By setting a specific ratio (0.75 to 0.85) between the first rod and the second rod, the scanning assembly can work in a wider range of viewing angles. The longer second rod helps to adjust the length of the position where the scanning assembly is placed, thereby expanding the scanning range and reducing the blind area, while the shorter first rod can help to keep the overall structure compact and avoid interference or collision. In addition, the above length setting can make the device better adapt to various types of goods, ensuring that high-quality 3D scanning data can be obtained regardless of how the goods are placed.
[0029] In this embodiment, the length of the first rod 221 is 200-210 cm, and the length of the second rod 222 is 250-260 cm.
[0030] Further, the scanning assembly 3 includes a 3D vision module 31, a base 32, and a driving structure 33. The driving structure 33 is installed on the first rod 221 or the second rod 222. The base 32 provides a stable mounting platform. The 3D vision module 31 is installed on the driving structure 33 through the base 32, ensuring that the 3D vision module 31 can remain stable during movement. The driving structure 33 is used to drive the base 32 to reciprocate along the length direction of the first rod 221 or the second rod 222.
[0031] The driving structure 33 of this embodiment allows the 3D vision module 31 to move freely at different heights and planes, which can cover a wider area, so that the entire device can better adapt to goods of various sizes and shapes. Especially when the size of the goods is large or the shape is complex, such linear motion helps to ensure that critical parts can be accurately scanned.
[0032] As shown in FIG. 4, the 3D vision module 31 is installed on the driving structure 33 through the base 32. The 3D vision module 31 is used to capture the 3D image of the goods. The 3D vision module 31 can be a 3D camera or a combination of multiple cameras. The 3D vision module 31 can be installed on the driving structure 33 in different ways, such as being mounted on the driving structure 33 or being integrated with the driving structure 33. Figure 3As shown, the driving structure 33 includes a guide rail 331, a first driving member 332, a driven structure, and a sliding block 333. The guide rail 331 provides a fixed path, the 3D vision module 31 is installed on the sliding block 333, and the sliding block 333 is slidingly installed on the guide rail 331, which ensures that the sliding block 333 (together with the 3D vision module 31 thereon) can move smoothly along a predetermined direction, guarantees the linearity and stability of the 3D vision module 31 during the scanning process, reduces the measurement error caused by deviation or jitter, and the first driving member 332 is usually a motor or other power source, which is responsible for providing the mechanical energy required for driving the sliding block 333 to move, and the output shaft thereof is connected with the driven structure. The driven structure can be a chain transmission structure, which is composed of a series of chain links and can transmit force between the gear teeth, has high transmission efficiency and reliability, one end of the chain structure is connected with the output shaft of the first driving member 332, and the other end is connected with the sliding block 333. As a common transmission mode, it is used to transmit the power generated by the first driving member 332 to the sliding block 343, so as to realize power transmission and drive the sliding block 333 to reciprocate along the extension direction of the guide rail 331. The entire driving structure 33 can automatically run under the control of a pre-set program, reducing the need for manual intervention, improving work efficiency, and also reducing the operation difficulty.
[0033] Further, the 3D vision module 31 includes a line laser 311 and a camera 312, which are installed on the base 32 in a spaced manner, and the camera 312 is arranged towards the scanning plane of the line laser 311.
[0034] The line laser 311 of the embodiment is used to emit a laser line projected onto the surface of the measured object. The laser beam will form a bright line on the surface of the object, and the shape and position of the bright line will change with the change of the profile of the object surface. The laser line image projected on the object by the line laser 311 is captured by the camera 312. By analyzing the changes of the laser line at different positions, the spatial coordinates of each point on the surface of the object can be calculated, and thus a three-dimensional model of the object can be constructed. That is, the combination of the line laser 311 and the camera 312 of the embodiment utilizes the principle of structured light. The laser line generated by the line laser 311 provides height information, and the camera 312 is used to capture this information. Since there is a fixed interval between the line laser 311 and the camera 312 and the camera 312 directly faces the laser line, very accurate distance measurement can be obtained, thereby improving the overall three-dimensional modeling accuracy.
[0035] It should be noted that the image acquisition and processing method of the embodiment can be processed by the existing processing method.
[0036] Further, the rotating assembly 1 comprises a second driving member 11, the support 2 comprises an axle seat 23 arranged at the end of the first support rod 21 away from the connecting rod 22, the second driving member 11 is a power source for rotation, usually a motor or other types of rotating driving devices, the output shaft of the second driving member 11 is connected with the axle seat 23, and the axle seat 23 provides a rotating fulcrum to ensure that the second driving member 11 can drive the entire support 2 (including the scanning assembly 3 mounted thereon) to make a circular motion around the goods, so that the scanning assembly 3 can comprehensively cover the goods from multiple angles.
[0037] Further, the rotating assembly 1 further comprises an encoder for detecting the rotating angle, and the encoder is electrically connected with the control unit, so that the preset angle can be reached every time, the predictability and consistency of the entire scanning process are improved, the operation process is simplified, the user does not need to manually calibrate the rotating angle, and the use threshold and technical requirements are reduced.
