[0019] The present invention also provides an application method of a nondestructive detection system for internal defects of a container, comprising the following steps: S. When detecting internal defects of a container, the container can be guided onto the surface of a conveyor belt until the conveyor belt conveys the container to the front of an infrared sensor, so that the infrared sensor can send a signal to a computer, so that the computer can control the electric push rod and the motor in sequence;

[0020] S1, and the electric push rod that is activated first will push the top sheet and the elastic push sheet at one end of the piston rod, and then drive the elastic push sheet to pass through the side plate and insert into each group of containers, so that the elastic push sheet can push the distance between the containers to be equal and at the same time make the top sheet stick to the outer surface of the container to limit the position of the container, and the pushed container will be flush with the threaded rod and the inkjet printer at the same time;

[0021] S2, and then the started motor will drive the second bevel gear to mesh with the first bevel gear to rotate, so that the first bevel gear can drive the central rotating rod to rotate in the installation cylinder, and an H-shaped groove is provided in the rotating rod, and a guide block is slidably installed in the H-shaped groove, and a threaded rod is fixedly installed on the lower surface of the guide block, and the lower end of the outer surface of the threaded rod simultaneously passes through the cone disk and is flush with the container, so that in the process of the rotating rod being driven to rotate, the threaded rod slidably installed inside can be driven to rotate together through the H-shaped groove, and the rotation of the threaded rod can be threaded in the cone disk, and the threaded rod can drive the guide block to slide down in the H-shaped groove through the force of the threaded transmission, so that the threaded rod can drive the 3D scanner and ultrasonic sensor on the lower surface to extend into the container and rotate at the same time, so that the 3D scanner and ultrasonic sensor can be fully moved in the container. The 3D scanner can scan and detect the inside of the container in all directions, covering all areas inside the container. The 3D shape and size information of the inside of the container, including defects and cracks, can be obtained by scanning with a 3D scanner. The 3D scanner generates point cloud data (i.e., the 3D coordinate points on the surface of the object) from the scanned information, and converts these data into a 3D model through a computer, usually in file formats such as .STL and .OBJ. The ultrasonic sensor is used to detect defects such as cracks, corrosion, and voids inside the container. If there are defects inside the container, the ultrasonic wave will encounter different media, and the characteristics of the reflected wave will change. The ultrasonic sensor can determine whether there are defects based on the reflected wave, and send a signal to the computer to extract the internal information of the defective container. In this step, the computer will use QR code based on the extracted key information. The Code Generator tool generates a QR code that contains metadata related to the 3D scan model and defect information such as cracks, corrosion, and voids, and enables the computer to send the generated QR code image data (or the content of the QR code) to the inkjet printer, and at the same time, the QR code data is stored in the online database of the computer.

When the rotating rod is driven to rotate, it can drive the outer surface transmission disk to rotate together, and the transmission disk can drive the other three groups of rotating rods to rotate in the same direction through the transmission belt installed on the outer surface, so that the rotating rod can drive the threaded rods in the other three groups of rotating rods to extend into the container together, so as to detect four groups of containers at the same time;

[0023] S4. After inspecting this batch of containers, the computer can control the electric push rod and the motor to pull back and reverse again, so that the electric push rod can pull the top sheet and the elastic push sheet out from between the containers to release the limiting force on the containers, and the reversal of the motor can pull the 3D scanner and the ultrasonic sensor at the lower end of the threaded rod out of the container, so that the conveyor belt can transport the four groups of containers that have passed the inspection, and in the process of transporting the containers, they will pass in front of the infrared sensor, and then the infrared sensor can record the number of containers passing in front of it through the computer, until four groups of containers pass in front of it, so that the infrared sensor can detect the fifth group of containers, and then the computer can start the electric push rod and the motor again in succession to separate and inspect the four groups of containers that have been transported.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. Through the design of side panels, conveyor belts, computers, inkjet printers, cone disks, infrared sensors, separation mechanisms and modeling detection mechanisms, when inspecting the internal defects of containers, the containers can be guided to the surface of the conveyor belt until the conveyor belt transports the containers to the front of the infrared sensor, which enables the infrared sensor to send a signal to the computer to control the separation mechanism and the modeling detection mechanism in sequence. The separation mechanism that is activated first will pass through the top of the side panel and be inserted between each group of containers, so that the separation mechanism can push the spacing between the containers to be equal and simultaneously stick to the outer surface of the container to limit the position of the container, so that the position of the container is relatively fixed and arranged neatly during the inspection process. This helps the modeling and testing mechanism to accurately test each container, avoiding inaccurate test results due to container position deviation, and the pushed container will be flush with the modeling and testing mechanism and the inkjet printer at the same time, and then the started modeling and testing mechanism will extend into the container and rotate at the same time, so that it can perform all-round scanning and testing operations in the container, and can fully obtain information inside the container, reduce detection blind spots, and improve detection accuracy. It is very useful for discovering defects inside the container, such as cracks, corrosion, and voids, and can generate point cloud data from the scanned information, that is, the three-dimensional coordinate points on the surface of the object, and convert these data into a three-dimensional model through a computer, usually .STL, .OBJ and other file formats. This visual result facilitates the inspectors to view the internal situation of the container more intuitively. Compared with the traditional two-dimensional detection results, the three-dimensional model can provide more comprehensive information, which is helpful to accurately determine the location and shape of the defect. If a defect is detected inside the container, the modeling detection mechanism will send a signal to the computer, so that the computer can extract the internal information of the defective container. In this step, the computer will generate a two-dimensional code based on the extracted key information through the QR Code Generator two-dimensional code generation tool. This two-dimensional code contains metadata related to the 3D scan model and defect information such as cracks, corrosion, and voids, and the computer will send the generated two-dimensional code image data (or the content of the two-dimensional code) to the inkjet printer, and at the same time, the two-dimensional code data will be stored in the computer's online database. The inkjet printer will spray on the surface of the defective container according to the two-dimensional code image sent by the computer, and then the staff can scan this two-dimensional code to access the 3D view of the container stored in the computer database, including cracks, holes, etc. After the inspection of this batch of containers, the computer can control the separation mechanism and the modeling detection mechanism to pull back and reverse again, so that the separation mechanism can be pulled out from between the containers to release the container restriction. force, and the reverse of the modeling detection mechanism can be pulled out of the container, so that the conveyor belt can transport the four groups of containers that have been tested, and in the process of transporting the containers, they will pass in front of the infrared sensor, so that the infrared sensor can record the number of containers passing in front of it through the computer, until four groups of containers pass in front of it, and then the infrared sensor can detect the fifth group of containers. Later, the computer will start the separation mechanism and the modeling detection mechanism again to separate and detect the four groups of containers transported, so that the system can continuously detect batches of containers. After each detection of four groups of containers, the computer can control the relevant mechanism again to perform the next round of separation and detection operations. This cyclic detection mechanism is suitable for large-scale container detection tasks, and there is no need to manually reset the equipment frequently. .

[0026] 2. Through the design of the motor, the rotating rod, the H-shaped slide, the 3D scanner, the ultrasonic sensor, the threaded rod and the guide block, after the containers are spaced and fixed, the startable motor will drive the second bevel gear to mesh with the first bevel gear to rotate, so that the first bevel gear can drive the central rotating rod to rotate in the installation tube, and the rotating rod is provided with an H-shaped slide, and the guide block is slidably installed in the H-shaped slide, and the threaded rod is fixedly installed on the lower surface of the guide block, and the lower end of the outer surface of the threaded rod is threaded through the cone disk and flush with the container, so that the rotating rod can be driven to rotate, and the threaded rod slidably installed inside can be driven to rotate together through the H-shaped slide, and the threaded rod is driven to rotate. The rotation of the cone disk can be threaded, and the threaded rod can drive the guide block to slide down in the H-shaped slide groove through the force of the threaded rod, so that the threaded rod can drive the 3D scanner and ultrasonic sensor on the lower surface to extend into the container and rotate at the same time, so that the 3D scanner and ultrasonic sensor can perform all-round scanning and detection in the container, covering all areas inside the container. The 3D shape and size information of the container can be obtained through the scanning of the 3D scanner, including defects and cracks, so that the 3D scanner generates point cloud data (i.e., the 3D coordinate points on the surface of the object) from the scanned information, and converts these data into a 3D model through a computer, usually .STL, .OBJ and other file formats, and the ultrasonic sensor is used to detect cracks, corrosion, voids and other defects inside the container. The collaborative work of multiple sensors can comprehensively detect the internal conditions of the container, reduce the limitations of single sensor detection, and improve the comprehensiveness of detection. If there are defects inside the container, the ultrasonic wave will encounter different media, and the characteristics of the reflected wave will change. The ultrasonic sensor can determine whether there are defects based on the reflected wave, and send a signal to the computer to extract the internal information of the defective container. In this step, the computer will use the QR Code to detect the defect based on the extracted key information. The Generator QR code generation tool generates a QR code that contains metadata related to the 3D scan model and defect information such as cracks, corrosion, and voids, and enables the computer to send the generated QR code image data (or the content of the QR code) to the inkjet printer, and at the same time, the QR code data will be stored in the online database of the computer. The inkjet printer will spray on the surface of the defective container according to the QR code image sent by the computer, and then the staff can scan the QR code to access the 3D view of the container stored in the computer database, including cracks, holes, etc. This method integrates the inspection results in a concise and easy to store and disseminate way, which is convenient for staff to access by scanning the QR code Detailed information such as the internal 3D view of the container in the database is conducive to the management and traceability of the test results. The entire test process, from the rotation of the rotating rod to the detection of the sensor, to data processing and QR code generation, coding and other operations, is a relatively automated process. This automation reduces manual intervention and reduces labor costs. In addition, due to the stability of the automated process, the efficiency and accuracy of the test can be further improved. In addition, when the rotating rod is driven to rotate, it can also drive the outer surface transmission disk to rotate. The transmission disk can drive the other three groups of rotating rods to rotate in the same direction through the transmission belt on the outer surface, so that the rotating rod can drive the threaded rods in the other three groups of rotating rods to extend into the container together, so as to detect four groups of containers at the same time.

[0027] 3. Through the design of the electric push rod, top sheet and elastic push sheet, after the conveyor belt transports the container to the front of the infrared sensor, the infrared sensor can send a signal to the computer to enable the computer to control the electric push rod to push the top sheet and the elastic push sheet at one end of the piston rod in turn, thereby driving the elastic push sheet to pass through the top of the side plate and insert into each group of containers. In this way, the elastic push sheet can push the spacing between the containers to be equal and at the same time make the top sheet stick to the outer surface of the container to limit the position of the container, thereby making the relative position of each container consistent during detection. This is very important for subsequent detection operations, because when the modeling detection mechanism is detecting, if the container spacing is uneven, it may lead to inconsistencies in detection angles, depths and other parameters, thereby affecting the accuracy of the detection results.

A guide block 312 is slidably mounted in the H-shaped slide groove 309. A threaded rod 306 is fixedly mounted on the lower surface of the guide block 312, so that the threaded rod 306 slides in the H-shaped slide groove 309 through the guide block 312. The lower end of the outer surface of the threaded rod 306 is threaded through the cone disk 109 at the same time, and the cone disk 109 is fixed. It is installed on the upper surface of the top plate 104 and is located below the installation tube 302, so that the lower surface of the threaded rod 306 can be threaded out to the lower surface of the top plate 104 and a 3D scanner 310 is fixedly installed on the end thereof, and an ultrasonic sensor 311 is fixedly installed on the other end of the 3D scanner 310. The signal transmitting ends of the 3D scanner 310 and the ultrasonic sensor 311 are both connected to the signal receiving end of the computer 105, and the computer 105 can send the internal data of the container detected by the 3D scanner 310 and the ultrasonic sensor 311 to the QR Code Generator two-dimensional code generation tool, extract the information of the scanned container, and generate a two-dimensional code;

[0045] The models of the 3D scanner 310 , the ultrasonic sensor 311 , and the infrared sensor 110 are HandySCAN 3D of Creaform, Honeywell Zephyr HPM Series, and Sharp GP2Y0A21YK0F, respectively.

[0046] A first bevel gear 307 is fixedly mounted on the outer surface of one set of rotating rods 303 . The first bevel gear 307 meshes with a second bevel gear 308 . The second bevel gear 308 rotates in the mounting tube 302 and is fixedly connected to the output shaft of the motor 301 . The motor 301 is fixedly mounted on the upper surface of the top plate 104 .

[0047] When the rotating rod 303 is driven to rotate, the threaded rod 306 slidably installed inside can be driven to rotate together through the H-shaped groove 309. The rotation of the threaded rod 306 can transmit the thread inside the cone disk 109, so that the threaded rod 306 can drive the guide block 312 to slide down in the H-shaped groove 309 through the force of the thread transmission, and then the threaded rod 306 can drive the 3D scanner 310 and the ultrasonic sensor 311 on the lower surface to extend into the container and rotate at the same time.

[0048] Transmission discs 304 are fixedly mounted on the outer surfaces of the four groups of rotating rods 303 , and transmission belts 305 are mounted on the outer surfaces of the transmission discs 304 , so that one group of rotating rods 303 can drive the other three groups of rotating rods 303 to rotate in the same direction.

[0049] Through the design of motor 301, rotating rod 303, H-shaped groove 309, 3D scanner 310, ultrasonic sensor 311, threaded rod 306 and guide block 312, after the containers are spaced and fixed, the startable motor 301 will drive the second bevel gear 308 to mesh with the first bevel gear 307 to rotate, so that the first bevel gear 307 can drive the central rotating rod 303 to rotate in the installation tube 302, and the rotating rod 303 is provided with an H-shaped groove 309, and the guide block 312 is slidably installed in the H-shaped groove 309, and the threaded rod 306 is fixedly installed on the lower surface of the guide block 312, and the lower end of the outer surface of the threaded rod 306 is simultaneously threaded through the cone disk 109 and flush with the container, so that during the process of the rotating rod 303 being driven to rotate, the threaded rod slidably installed inside can be driven through the H-shaped groove 309. 306 rotates together, and the rotation of the threaded rod 306 can be threaded in the cone disk 109, so that the threaded rod 306 can drive the guide block 312 to slide down in the H-shaped slide groove 309 through the force of the threaded transmission, and then the threaded rod 306 can drive the 3D scanner 310 and the ultrasonic sensor 311 on the lower surface to extend into the container and rotate at the same time, so that the 3D scanner 310 and the ultrasonic sensor 311 can perform all-round scanning and detection in the container, covering various areas inside the container, and the 3D shape and size information of the container can be obtained through the scanning of the 3D scanner 310, including defects and cracks, so that the 3D scanner 310 generates point cloud data, i.e., three-dimensional coordinate points on the surface of the object, from the scanned information, and converts these data into a three-dimensional model through the computer 105, usually .STL,.OBJ and other file formats, and the ultrasonic sensor 311 is used to detect defects such as cracks, corrosion, and cavities inside the container. The collaborative work of multiple sensors can comprehensively detect the internal conditions of the container, reduce the limitations of single sensor detection, and improve the comprehensiveness of detection. If there are defects inside the container, the ultrasonic wave will encounter different media, and the characteristics of the reflected wave will change, which will enable the ultrasonic sensor 311 to determine whether there are defects based on the reflected wave. The ultrasonic sensor 311 will send a signal to the computer 105, so that the computer 105 can extract the internal information of the defective container. In this step, the computer 105 will use the QR Code to detect the internal defects of the container based on the extracted key information. The Generator QR code generation tool generates a QR code, which contains metadata related to the 3D scan model and defect information such as cracks, corrosion, and voids, and enables the computer 105 to send the generated QR code image data or the content of the QR code to the inkjet printer 108, and at the same time, the QR code data will be stored in the online database of the computer 105. The inkjet printer 108 will spray on the surface of the container with defects according to the QR code image sent by the computer 105, and then the staff can scan the QR code to access the 3D view of the inside of the container stored in the database of the computer 105, including cracks, holes, etc. This method integrates the inspection results in a concise and easy to store and disseminate manner, making it convenient for the staff to access the containers in the database by scanning the QR code Detailed information such as the internal 3D view is conducive to the management and traceability of the test results. The entire test process, from the rotation of the rotating rod 303 to the detection of the sensor, to data processing and QR code generation, coding and other operations, is a relatively automated process. This automation reduces manual intervention and reduces labor costs. In addition, due to the stability of the automated process, the efficiency and accuracy of the test can be further improved. In the process of the rotating rod 303 being driven to rotate, it can also drive the outer surface transmission disk 304 to rotate. The transmission disk 304 can drive the other three groups of rotating rods 303 to rotate in the same direction through the transmission belt 305 on the outer surface, so that the rotating rod 303 can drive the threaded rods 306 in the other three groups of rotating rods 303 to extend into the container together, so as to detect four groups of containers at the same time.

[0050] like Figure 8 As shown, the separation mechanism 2 includes an electric push rod 201, which is fixedly mounted on the lower surface of the mounting plate 102. A top plate 202 is fixedly mounted on one end of the piston rod of the electric push rod 201, and an elastic push plate 203 is fixedly mounted on one end of the top plate 202. The top plate 202 and the elastic push plate 203 slide on the upper surface of the supporting plate 107.

[0051] The top sheet 202 and the elastic push sheet 203 can be pushed through the connecting port of the side panel 101 into the upper end of the conveyor belt 103 by the electric push rod 201, so that the elastic push sheet 203 can be inserted between each group of containers, so that the elastic push sheet 203 can push the distances between the containers to be equal and at the same time make the top sheet 202 stick to the outer surface of the container to limit the position of the container, and the pushed container will be flush with the threaded rod 306 at the same time, and the electric push rod 201 is controlled by the computer 105.

[0052] Through the design of the electric push rod 201, the top sheet 202 and the elastic push sheet 203, after the conveyor belt 103 transports the container to the front of the infrared sensor 110, the infrared sensor 110 can send a signal to the computer 105, so that the computer 105 can control the electric push rod 201 to push the top sheet 202 and the elastic push sheet 203 at one end of the piston rod in turn, thereby driving the elastic push sheet 203 to pass through the side plate 101 and insert into each group of containers, so that the elastic push sheet 203 can push the distance between the containers to be equal and at the same time make the top sheet 202 stick to the outer surface of the container to limit the position of the container, thereby making the relative position of each container consistent during detection, which is very important for subsequent detection operations, because when the modeling detection mechanism 3 is detecting, if the container spacing is uneven, it may cause inconsistency in detection angle, depth and other parameters, thereby affecting the accuracy of the detection result.

[0053] This embodiment also provides an application method of a nondestructive detection system for internal defects of a container, comprising the following steps:

[0054] S1. When inspecting internal defects of a container, the container can be guided onto the surface of the conveyor belt 103 until the conveyor belt 103 conveys the container to the front of the infrared sensor 110, so that the infrared sensor 110 can send a signal to the computer 105, so that the computer 105 can control the electric push rod 201 and the motor 301 in sequence;

[0055] S2, the electric push rod 201 that is activated first will push the top sheet 202 and the elastic push sheet 203 at one end of the piston rod, and then drive the elastic push sheet 203 to pass through the side plate 101 and insert into each group of containers, so that the elastic push sheet 203 can push the distance between the containers to be equal and at the same time make the top sheet 202 stick to the outer surface of the container to limit the position of the container, and the pushed container will be flush with the threaded rod 306 and the inkjet printer 108 at the same time;

[0056] S3, then the started motor 301 will drive the second bevel gear 308 to mesh with the first bevel gear 307 to rotate, so that the first bevel gear 307 can drive the central rotating rod 303 to rotate in the installation tube 302, and the rotating rod 303 is provided with an H-shaped slide groove 309, and a guide block 312 is slidably installed in the H-shaped slide groove 309, and a threaded rod 306 is fixedly installed on the lower surface of the guide block 312, and the lower end of the outer surface of the threaded rod 306 is threaded through the cone disk 109 and is flush with the container. In the process of the rotating rod 303 being driven to rotate, the threaded rod 306 slidably installed inside can be driven to rotate together through the H-shaped slide groove 309, and the rotation of the threaded rod 306 can be threadedly transmitted in the cone disk 109, so that the threaded rod 306 can drive the guide block 312 to slide down in the H-shaped slide groove 309 through the force of the threaded transmission, and then the threaded rod 306 can drive the 3D scanner 310 and the ultrasonic sensor 311 on the lower surface to extend into the container and rotate at the same time, so as to The 3D scanner 310 and the ultrasonic sensor 311 can perform all-round scanning and detection in the container, covering all areas inside the container. The 3D shape and size information of the inside of the container, including defects, cracks, etc., can be obtained through the scanning of the 3D scanner 310, so that the 3D scanner 310 generates point cloud data, i.e., three-dimensional coordinate points on the surface of the object, from the scanned information, and converts these data into a three-dimensional model through the computer 105, usually in .STL, .OBJ and other file formats, and the ultrasonic sensor 311 is used to detect defects such as cracks, corrosion, and cavities inside the container. If there are defects inside the container, the ultrasonic wave will encounter different media, and the characteristics of the reflected wave will change, which can enable the ultrasonic sensor 311 to determine whether there are defects based on the situation of the reflected wave, and the ultrasonic sensor 311 will send a signal to the computer 105, so that the computer 105 can extract the internal information of the defective container. In this step, the computer 105 will use the QR code to calculate the internal information of the defective container based on the extracted key information. The Code Generator generates a QR code containing metadata related to the 3D scanned model and defect information such as cracks, corrosion, and voids, and enables the computer 105 to send the generated QR code image data or the content of the QR code to the inkjet printer 108, and also stores the QR code data in the online database of the computer 105. The inkjet printer 108 sprays the QR code image sent by the computer 105 on the surface of the container with defects, and then allows the staff to scan the QR code to access the 3D view of the inside of the container stored in the database of the computer 105, including cracks and holes;

[0057] S4, when the rotating rod 303 is driven to rotate, the outer surface transmission disk 304 can be driven to rotate together, and the transmission disk 304 can drive the other three groups of rotating rods 303 to rotate in the same direction through the transmission belt 305 on the outer surface, so that the rotating rod 303 can drive the threaded rods 306 in the other three groups of rotating rods 303 to extend into the container together, so as to detect four groups of containers at the same time;

[0058] S5. After inspecting this batch of containers, the computer 105 can control the electric push rod 201 and the motor 301 to pull back and reverse again, so that the electric push rod 201 can pull the top sheet 202 and the elastic push sheet 203 out from between the containers to release the limiting force on the containers, and the reversal of the motor 301 can pull the 3D scanner 310 and the ultrasonic sensor 311 at the lower end of the threaded rod 306 out of the container, so that the conveyor belt 103 can transport the four groups of containers that have passed the inspection, and in the process of transporting the containers, they will pass in front of the infrared sensor 110, so that the infrared sensor 110 can record the number of containers passing in front of it through the computer 105, until four groups of containers pass in front of it, so that the infrared sensor 110 can detect the fifth group of containers, and then the computer 105 can start the electric push rod 201 and the motor 301 again to separate and inspect the four groups of containers that have been transported.

[0059] According to the above technical solution, the working steps of this solution are summarized and sorted out: when inspecting the internal defects of the container, the container can be guided to the surface of the conveyor belt 103 until the conveyor belt 103 conveys the container to the front of the infrared sensor 110, so that the infrared sensor 110 can send a signal to the computer 105, so that the computer 105 can control the electric push rod 201 and the motor 301 in sequence, and the electric push rod 201 that is started first will push the top plate 202 and the elastic push plate 203 at one end of the piston rod, and then can drive the elastic push plate 203 to pass through the side plate 101 and insert it into the top plate 101. The push piece 203 is inserted between each group of containers, so that the elastic push piece 203 can push the distance between the containers to be equal and at the same time make the top piece 202 stick to the outer surface of the container to limit the position of the container, and the pushed container will be flush with the threaded rod 306 and the inkjet printer 108 at the same time, and then the started motor 301 will drive the second bevel gear 308 to mesh with the first bevel gear 307 to rotate, and then the first bevel gear 307 can drive the central rotating rod 303 to rotate in the installation cylinder 302, and the rotating rod 303 is provided with an H-shaped slide groove 309, and the H-shaped slide groove 309 The guide block 312 is installed in the inner sliding mode, and the threaded rod 306 is fixedly installed on the lower surface of the guide block 312, and the lower end of the outer surface of the threaded rod 306 is threaded through the cone disk 109 and is flush with the container, so that when the rotating rod 303 is driven to rotate, the threaded rod 306 installed in the inner sliding mode can be driven to rotate together through the H-shaped slide groove 309, and the rotation of the threaded rod 306 can be threaded in the cone disk 109, so that the threaded rod 306 can drive the guide block 312 to slide down in the H-shaped slide groove 309 through the force of the threaded transmission, so that the threaded rod 306 can drive The 3D scanner 310 and ultrasonic sensor 311 on the lower surface extend into the container and rotate at the same time, so that the 3D scanner 310 and ultrasonic sensor 311 can perform all-round scanning and detection in the container, covering all areas inside the container, and the 3D shape and size information of the container can be obtained through the scanning of the 3D scanner 310, including defects, cracks, etc., so that the 3D scanner 310 generates point cloud data, i.e., 3D coordinate points on the surface of the object, from the scanned information, and converts these data into a 3D model through the computer 105, usually .STL, .OBJ and other file formats, and the ultrasonic sensor 311 is used to detect defects such as cracks, corrosion, and cavities inside the container. If there are defects inside the container, the ultrasonic wave will encounter different media, and the characteristics of the reflected wave will change, which will enable the ultrasonic sensor 311 to determine whether there are defects based on the reflected wave. The ultrasonic sensor 311 will send a signal to the computer 105, so that the computer 105 can extract the internal information of the defective container. In this step, the computer 105 will use QR code to extract the internal information of the defective container based on the extracted key information. The CodeGenerator QR code generation tool generates a QR code, which contains metadata related to the 3D scan model and defect information such as cracks, corrosion, and voids, and enables the computer 105 to send the generated QR code image data or the content of the QR code to the inkjet printer 108, and at the same time, the QR code data will be stored in the online database of the computer 105. The inkjet printer 108 will spray on the surface of the defective container according to the QR code image sent by the computer 105, and then the staff can scan the QR code to access the 3D view of the inside of the container stored in the database of the computer 105, including cracks, holes, etc., and the rotating rod 303 can be driven to rotate when it is driven to rotate, and the transmission disk 304 can drive the other three groups of rotating rods 303 to rotate in the same direction through the transmission belt 305 installed on the outer surface, so that the rotating rod 303 can drive the threaded rods 303 in the other three groups of rotating rods 303. 06 together extend into the container to simultaneously inspect four groups of containers. After inspecting this batch of containers, the computer 105 can control the electric push rod 201 and the motor 301 to pull back and reverse again, so that the electric push rod 201 can pull the top sheet 202 and the elastic push sheet 203 out from between the containers to release the container's limiting force, and the reversal of the motor 301 can pull the 3D scanner 310 and the ultrasonic sensor 311 at the lower end of the threaded rod 306 out of the container, so that the conveyor belt 103 can transport the four groups of containers that have been inspected, and in the process of transporting the containers, they will all pass in front of the infrared sensor 110, so that the infrared sensor 110 can record the number of containers passing in front of it through the computer 105, until four groups of containers pass in front of it, so that the infrared sensor 110 can detect the fifth group of containers, and then the computer 105 can start the electric push rod 201 and the motor 301 again to separate and inspect the four groups of containers that have been transported. .

When inspecting internal defects of a container, the container is guided onto the surface of a conveyor belt (103) until the conveyor belt (103) conveys the container to the front of an infrared sensor (110), so that the infrared sensor (110) sends a signal to a computer (105), so that the computer (105) controls the electric push rod (201) and the motor (301) in sequence; S2, the electric push rod (201) that is activated first will push the top plate (202) and the elastic push plate (203) at one end of the piston rod, thereby driving the elastic push plate (203) to pass through the side plate (101) and insert into each group of containers, so that the elastic push plate (203) can push the distance between the containers to be equal and at the same time make the top plate (202) stick to the outer surface of the container to limit the position of the container, and the pushed container will be flush with the threaded rod (306) and the inkjet printer (108) at the same time; S3, the motor (301) that is then started drives the second bevel gear (308) to mesh with the first bevel gear (307) to rotate, thereby enabling the first bevel gear (307) to drive the central rotating rod (303) to rotate in the mounting tube (302), and the rotating rod (303) is provided with an H-shaped slide groove (309), and a guide block (312) is slidably installed in the H-shaped slide groove (309), and a threaded rod (306) is fixedly installed on the lower surface of the guide block (312), and the outer surface of the threaded rod (306) The lower end of the surface is threaded through the cone disk (109) and is flush with the container, so that when the rotating rod (303) is driven to rotate, the threaded rod (306) installed inside the H-shaped slide groove (309) can be driven to rotate together, and the rotation of the threaded rod (306) can be threaded in the cone disk (109), so that the threaded rod (306) can drive the guide block (312) to slide down in the H-shaped slide groove (309) through the force of the threaded transmission, so that the threaded rod (306) can drive the 3D scanning of the lower surface The 3D scanner (310) and the ultrasonic sensor (311) extend into the container and rotate at the same time, so that the 3D scanner (310) and the ultrasonic sensor (311) can perform all-round scanning and detection in the container, covering various areas inside the container, and obtain the three-dimensional shape and size information of the container through the scanning of the 3D scanner (310), so that the 3D scanner (310) generates point cloud data from the scanned information, and converts these data into a three-dimensional model through the computer (105), and the ultrasonic sensor (311) is used to detect cracks, corrosion, and voids inside the container. If there are defects inside the container, the ultrasonic wave will encounter different media, and the characteristics of the reflected wave will change, so that the ultrasonic sensor 311 can determine whether there are defects based on the situation of the reflected wave, and the ultrasonic sensor (311) will send a signal to the computer (105), so that the computer (105) can extract the internal information of the container with defects. In this step, the computer (105) will use QR code to calculate the internal information of the container based on the extracted key information. The Code Generator two-dimensional code generation tool generates a two-dimensional code, which contains metadata related to the 3D scan model and crack, corrosion, and void defect information, and enables the computer (105) to send the generated two-dimensional code image data to the inkjet printer (108), and at the same time, the two-dimensional code data is also stored in the online database of the computer (105). The inkjet printer (108) sprays on the surface of the container with defects according to the two-dimensional code image sent by the computer (105), and then allows the staff to scan the two-dimensional code to access the 3D view of the inside of the container stored in the database of the computer (105), including cracks and holes; S4, when the rotating rod (303) is driven to rotate, the transmission disc (304) on the outer surface can be driven to rotate together, and the transmission disc (304) can drive the other three groups of rotating rods (303) to rotate together in the same direction through the transmission belt (305) mounted on the outer surface, so that the rotating rod (303) can drive the threaded rods (306) in the other three groups of rotating rods (303) to extend into the container together, so as to detect four groups of containers at the same time; S5. After inspecting the batch of containers, the computer (105) controls the electric push rod (201) and the motor (301) to pull back and reverse again, so that the electric push rod (201) pulls the top sheet (202) and the elastic push sheet (203) out from between the containers to release the fixing force on the containers. The reverse rotation of the motor (301) pulls the 3D scanner (310) and the ultrasonic sensor (311) at the lower end of the threaded rod (306) out of the container, so that the conveyor belt (103) can convey the four groups of containers that have been inspected. In the process of conveying the containers, the conveyor belt (103) will pass in front of the infrared sensor (110), so that the infrared sensor (110) can record the number of containers that have passed in front of the infrared sensor (110) through the computer (105). After four groups of containers have passed in front of the infrared sensor (110), the fifth group of containers can be detected, and then the computer (105) can start the electric push rod (201) and the motor (301) again to separate and inspect the four groups of containers that have been conveyed.
