[0020] The present invention proposes an on-board intelligent material cabinet for locomotives. The on-board intelligent material cabinet for locomotives is provided with a material management device based on RFID wireless radio frequency identification technology. The tracking, monitoring and management of materials are fully automated and intelligent through the material management device, which solves the problems of high error rate in manual supervision, long-term forgetting to return materials and difficulty in long-term preservation of paper files. Through the intelligent management and control of materials, the labor cost is reduced, the convenience and accuracy of material management and control are improved, the management effect is good, and the management efficiency is high.

[0021] Specifically, in one embodiment of the invention, Figure 1-Figure 4 As shown, the locomotive on-board intelligent material cabinet includes a cabinet body 1 and a partition 2 and an electric control box 4 arranged in the cabinet body 1. The partition 2 defines a large cabinet room 5 in the cabinet body 1. The entrance and exit of the large cabinet room 5 are provided with a cabinet door 8. The large cabinet room 5 is provided with an electric lock 15, a track 16 and a drawer 7. The electric lock 15 is used to lock the cabinet door 8. The electric lock 15 is controlled by the electric control box 4. When the electric control box 4 sends an unlocking command to the electric lock 15, the electric lock 15 unlocks the cabinet door 8. At this time, people can open the cabinet door 8 from the outside. When the cabinet door 8 is closed, the electric lock 15 locks the cabinet door 8. At this time, people cannot open the cabinet door 8 from the outside.

[0022] In this embodiment, the drawer 7 is slidably mounted on a track 16, and the track 16 is fixedly mounted on the inner wall of the large cabinet chamber 5. After opening the cabinet door 8, the drawer 7 is pulled to slide along the track 16 so that most of the drawer 7 extends out of the large cabinet chamber 5, and then the materials in the drawer 7 can be taken out. After the materials are taken out, the drawer 7 is pushed back and the cabinet door 8 is closed.

[0023] In this embodiment, if Figure 4As shown, a reader / writer 12 is arranged just above the drawer 7, and the reader / writer 12 is fixedly mounted on a mounting frame 11, and the mounting frame 11 is fixedly connected to the inner wall of the large cabinet 5. The drawer 7 is used to place materials, and electronic tags are arranged on the materials. The reader / writer 12 can read and write the electronic tags on all the materials in the drawer 7. With this design, after a person takes away some materials, the remaining materials in the drawer 7 are detected by the reader / writer 12, so as to judge which materials the person has taken away, and then bind with the person who took the materials to accurately manage the materials, as shown in FIG. Figure 1-Figure 4 As shown, the electric control box 4 is provided with a touch screen 13 and a camera 14. The touch screen 13 is used for human-computer interaction with the locomotive-mounted intelligent material cabinet of this embodiment, and for displaying material flow information. It has information including borrowed or returned material information, personnel information, time information, and material information that has not been returned for a long time for personnel to view. In addition, the touch screen also provides personnel with a variety of query functions such as borrowing and returning record query, material information query, timeout non-return reminder, and material usage frequency information query. When the personnel log in, they can check these detailed and real-time data records at any time, which improves the efficiency of material management; the camera 14 is used to capture the facial information of the personnel who are ready to borrow or return materials, and transmit the captured information to the controller in the electric control box 4 for verification. If the verification is qualified, the electric control box 4 sends an unlocking command to the electric control lock 15, and the personnel can open the cabinet door 8 to take away or return materials. On the contrary, if the verification is unqualified, the electric control lock 15 keeps the cabinet door 8 locked to protect the safety of the materials.

[0024] In this embodiment, the electric control box 4 is connected to the reader / writer 12 and the electric lock 15 by signal. The read and write data of the reader / writer 12 is displayed on the touch screen 13. The reader / writer 12 and the electronic tag constitute a material management device 1 of this embodiment, which relies on RFID wireless radio frequency identification technology to identify each material.

[0025] Specifically, the use process of the locomotive-mounted intelligent material cabinet including the cabinet body 1 of this embodiment is as follows: 1. The person who wants to borrow or return materials comes to the material cabinet, and the camera 14 captures the person's facial information and sends it to the electric control box 4 for verification. After the verification is successful, the electric control box 4 sends an unlocking command to the electric lock 15, and then the person opens the cabinet door 8 to take away or return the materials; 2. After the action of taking away or returning materials is completed, the personnel closes the cabinet door 8, and the electric lock 15 automatically locks the cabinet door 8. Then the controller in the electric control box 4 controls the reader 12 to read and write the remaining material information in the drawer 7. Then, combined with the remaining material information in the drawer 7 read and written by the reader 12 last time, it is determined what kind of material the personnel took away or returned before. Then the controller binds the material information with the personnel information, generates material flow information and stores it in the memory in the electric control box 4, and displays it on the touch screen 13 for personnel to view. Personnel can view the borrowed or returned material information, personnel information, time information, and material information that has not been returned for a long time through the touch screen 13. This information can be stored for a long time in the database of the memory, and can be viewed or downloaded at any time. The management and control of materials is transformed from traditional paper registration to the upper computer, which solves the problems of high error rate in manual supervision, long-term non-return of materials, and difficulty in long-term preservation of paper files.

[0026] In the locomotive-mounted intelligent material cabinet of the present embodiment, each time a person takes away or returns a material and closes the cabinet door 8, the controller controls the reader / writer 12 to read and write the remaining material information in the drawer 7. This process not only ensures the real-time update of the material data, but also greatly improves the accuracy and efficiency of management. Subsequently, the controller performs intelligent analysis and processing on the read material data, obtains the material information taken away or returned, and uploads it to the database for storage. The management and control of materials is transformed from traditional paper registration to the upper computer, which solves the problems of high error rate in manual supervision, long-term non-return of materials, and difficulty in long-term preservation of paper files.

[0027] The locomotive-mounted intelligent material cabinet of this embodiment arranges materials of different attributes in different areas according to factors such as the purpose and frequency of use of the materials. By setting up multiple layers of drawers 7 and setting a unique identification electronic tag for each material, relying on advanced RFID wireless identification technology, the material management device can instantly capture and accurately identify the electronic tag information on each material, realizing the instant acquisition and efficient integration of material information at the data layer. Subsequently, these detailed data are seamlessly connected to the cloud database by the processor, building a comprehensive and dynamic material management network and realizing data sharing. This eliminates the need for full-time material management personnel; reduces the number of operating steps; and uses tools that evolve from the registration side that continues to increase over time to a large-capacity industrial computer, and the data can be transferred to a mobile hard disk through the USB interface of the industrial computer.

[0028] In the locomotive-mounted intelligent material cabinet of the present embodiment, the material management device 1 adopts RFID wireless radio frequency identification technology. Radio frequency identification (RFID) is the abbreviation of Radio Frequency Identification. The basic principle of RFID technology is to use radio waves for communication to realize the information transmission between the reader 12 and the electronic tag. Specifically, when the electronic tag enters the working area of ​​the reader 12, the reader 12 transmits a radio frequency signal through the antenna to activate the electronic tag. The electronic tag obtains energy by means of induced current or its own power supply (in active tags). After activation, it sends its own encoded information to the reader 12 through the built-in antenna. The reader 12 receives and demodulates the signal, and then transmits the valid information to the application software system for further processing. A complete RFID system usually consists of the following four parts: Electronic tag (Tag): Electronic tags are information carriers in RFID systems, usually composed of a built-in antenna and an RFID chip. The chip stores identification information of the item to be identified, such as a globally unique ID code. Depending on the power supply method, electronic tags can be divided into passive tags, active tags, and semi-active tags.

[0029] Reader 12: Reader 12 is the core device in the RFID system, responsible for reading (and writing) the information in the electronic tag. The reader 12 activates the electronic tag by transmitting a radio frequency signal through the antenna and receives the information sent by the electronic tag. The reader 12 includes a control unit, a wireless transceiver front end, and a communication interface.

[0030] Antenna: transmits signals between the tag and the reader / writer 12.

[0031] Application software system: The application software system is responsible for decoding, processing and applying the data read by the reader 12. Through the communication interface of the reader 12, the application software system can obtain the data in the electronic tag in real time to achieve tracking, monitoring and management of the item.

[0032] The technical features of the material management device 1 of this embodiment are: Efficient and fast: RFID technology can achieve fast and accurate contactless identification, greatly improving the efficiency of data collection and processing.

[0033] Long-distance identification: Compared with traditional identification methods such as barcodes and QR codes, RFID technology has a longer identification distance and provides greater flexibility and convenience.

[0034] Large data storage capacity: RFID tags can store rich information, including detailed data such as the item’s serial number, production date, batch number, etc.

[0035] Strong environmental adaptability: RFID technology can work normally in various harsh environments and has strong environmental adaptability.

[0036] In this embodiment, an intelligent software management system is implanted in the processor in the electric control box 4, and the material flow is fully automatically and intelligently controlled by hardware such as the material management device 1, the camera 14, and the touch screen 13. The intelligent software management system uses the Visual Basic programming language. Visual Basic (VB for short) is a high-level programming language based on the Basic programming language developed by Microsoft. It is designed specifically for the development of Windows applications and aims to simplify the application creation process and make it more friendly to non-professional programmers. Since its launch in 1991, Visual Basic has gone through multiple versions of iterations. The latest version is Visual Basic .NET (VB.NET for short) based on the .NET framework. The language features of the VisualBasic programming language include: Event-driven programming: VB is a typical representative of event-driven programming, which allows the program to execute code based on user actions (such as clicking a button) or other events (such as a file opening).

[0037] Visual design: VB's IDE provides the function of dragging and dropping controls, allowing developers to design user interfaces intuitively.

[0038] Easy to learn: The syntax is simple and intuitive, making it ideal for beginners and developers who want to develop applications quickly.

[0039] Integrated environment: Visual Studio provides a powerful development environment, including debugger, code editor, project management tools, etc.

[0040] Cross-platform support: While traditional VB6 is limited to the Windows platform, VB.NET already supports cross-platform development, including Windows, Linux, and macOS, through .NET Core and .NET 5+.

[0041] The locomotive-mounted intelligent material cabinet of the present embodiment is provided with a material management device 1 based on RFID wireless radio frequency identification technology. The material management device 1 cooperates with the electric control box 4 to realize the full automation and intelligence of material tracking, monitoring and management. There is no need to configure full-time material management personnel to supervise the whole process of material flow, and paper registration is not used. It is convenient to carry and transfer, and data sharing is realized. It solves the problems of high error rate of manual supervision, long-term forgetting of materials and difficulty in long-term preservation of paper files. Through intelligent management and control of materials, labor costs are reduced, the convenience and accuracy of material management and control are improved, and the management effect is good and the management efficiency is high.

[0042] In the present embodiment, the electronic components in the electric control box 4 of the locomotive on-board intelligent material cabinet and the material management device are all electronic components that can work normally at -40℃-+70℃, so as to achieve use in high and low temperature environments. At the same time, a membrane made of special materials is used to fix the materials in the drawer 7, so that normal use is achieved under impact and vibration conditions during the running of the locomotive. In addition, electromagnetic compatibility can be achieved by adding filters and other methods to avoid the situation where the locomotive on-board intelligent material cabinet of the present embodiment is interfered with by other electrical equipment on the locomotive and cannot be used normally, so that the locomotive on-board intelligent material cabinet of the present embodiment can adapt to the complex working conditions when used on the locomotive.

[0043] Furthermore, in this embodiment, if Figure 3 and Figure 4 As shown, a limit device 9 and a distance measuring device 10 are arranged in the large cabinet chamber 5, and the limit device 9 and the distance measuring device 10 are connected to the signal of the electric control box 4. The distance measuring device 10 is used to measure the position of the drawer 7 on the track 16, and the limit device 9 is used to prevent the drawer 7 from sliding on the track 16, so that the drawer 7 is completely located in the large cabinet chamber 5, so as to prevent the drawer 7 from accidentally sliding out of the large cabinet chamber 5 and blocking the shooting line of sight of the visual camera 64, thereby affecting the operation of the visual camera 64.

[0044] Specifically, Figure 3 and Figure 4 As shown, each drawer 7 is provided with a corresponding limit device 9 and a distance measuring device 10. When all the drawers 7 are in the large cabinet chamber 5 and none of the drawers 7 is pulled out, all the limit devices 9 are reset and do not prevent the drawers 7 from sliding on the track 16. When a certain drawer 7 is pulled out, the distance data detected by the distance measuring device 10 corresponding to the drawer 7 changes, and the distance data detected by the distance measuring devices 10 corresponding to other drawers 7 do not change. Based on this, the controller in the electric control box 4 controls the limit devices 9 corresponding to other drawers 7 to prevent other drawers 7 from sliding on the track 16, ensuring that only one drawer 7 is pulled out at a certain time, avoiding that other drawers 7 block the shooting line of sight of the visual camera 64 after being pulled out, and affecting the operation of the visual camera 64. When the pulled out drawer 7 is pushed back into the large cabinet chamber 5, none of the drawers 7 is pulled out, and all the limit devices 9 are reset again and do not prevent the drawers 7 from sliding on the track 16. When a certain drawer 7 is pulled out again, the limit devices 9 corresponding to other drawers 7 are activated to prevent other drawers 7 from sliding on the track 16.

[0045] In this embodiment, if Figure 1-Figure 4As shown, there is a pair of partitions 2, which are spaced apart from each other, and the electric control box 4 is located between the pair of partitions 2. The large cabinet room 5 is located below the partition 2 at the lower end of the electric control box 4. The partition 2 at the upper end of the electric control box 4 defines a small cabinet room 3 in the cabinet body 1 in the area above the partition 2. The small cabinet room 3 is used to store some tools and accessories for repairing the locomotive on-board intelligent material cabinet of this embodiment, so that when the locomotive on-board intelligent material cabinet fails, the locomotive on-board intelligent material cabinet can be repaired and the faulty parts can be replaced in time.

[0046] Furthermore, in this embodiment, if Figure 5 As shown, a material management device 2 6 is installed on the electrical control box 4 in a sliding manner. The material management device 2 6 is used to solve the problem of cumbersome material management process and low material flow efficiency when multiple people queue up to take or return materials and must first close the cabinet door 8 for personnel verification and then open the cabinet door 8, so as to facilitate personnel to take materials. Because after the aforementioned personnel closed the cabinet door 8, the electric lock 15 automatically locked the cabinet door 8, and then the controller in the electric control box 4 controlled the reader / writer 12 to read and write the remaining material information in the drawer 7, and then combined with the remaining material information in the drawer 7 read and written by the reader / writer 12 last time, it was determined what kind of material the previous personnel took away or returned, and then the controller bound the material information with the personnel information to generate material flow information. Therefore, in order to ensure accurate and orderly material management, each person needs to close the cabinet door 8 after taking away or putting back the material. After the reader / writer 12 has read and written the remaining material information in the drawer 7 and the touch screen 13 has generated the material flow information of the taken or returned material, the next person can perform human eye recognition, open the cabinet door 8, and take away or return the material again. Therefore, when there are many people returning or taking materials in front of the locomotive on-board intelligent material cabinet, they need to line up one by one to perform face recognition-open the door-take away or return materials-close the door-read and write. The remaining material information in the drawer 7 read and written by the device 12 - the controller generates material flow information - the next person performs face recognition on the material taking and returning process. The material management process is cumbersome, the material flow efficiency is low, and it wastes people's time. Based on this, a material management device 2 6 is designed. The material management device 2 6 uses a visual camera 64 to cooperate with the camera 14 to identify the materials taken or returned by each person. When the cabinet door 8 is closed and no one opens the cabinet door 8 again for a long time, the electrical control box 4 analyzes and processes the information captured by the visual camera 64 and the camera 14, and then compares and analyzes the remaining material information in the drawer 7 retrieved by the material management device 1, and determines which materials were taken or returned by multiple people during the long-term opening of the cabinet door 8. This design saves the trouble of frequently opening and closing the cabinet door 8, improves the material flow efficiency, simplifies the material management process, and avoids the increasingly long queues of people in front of the locomotive on-board intelligent material cabinet.

[0047] Specifically, Figure 5As shown, the material management device 2 6 includes: a sliding box 62, a visual camera 64 and a push-pull device 63. The sliding box 62 is slidably installed in the electric control box 4. The sliding of the sliding box 62 can make one end of it extend out of the electric control box 4, and the lower surface of the sliding box 62 is open; the visual camera 64 is arranged inside one end of the sliding box 62, and the shooting direction of the visual camera 64 is downward; the pushing-pull device 63 is arranged in the electric control box 4 and is connected to the sliding box 62, and is used to drive the sliding box 62 to slide so that the visual camera 64 extends out of the electric control box 4 to shoot the image below the visual camera 64. The drawer 7 and the cabinet door 8 are located below the visual camera 64. The setting of the limit device 9 and the distance measuring device 10 ensures that only one drawer 7 is pulled out at a certain time, ensuring that the visual camera 64 can capture the image of the drawer 7, and there will be no problem that other drawers 7 are also pulled out to block the shooting line of sight of the visual camera 64, thereby ensuring the normal operation of the material management device 2 6.

[0048] Further, such as Figure 5 As shown, the electric control box 4 is provided with a slide 61 which can be detachably fixed therein, the slide box 62 is slidably installed therein, the push-pull device 63 is fixedly installed therein, and the push-pull device 63 pushes the slide box 62 to slide so that one end of the slide box 62 extends out of the slide 61. This design makes it convenient to dismantle the material management device 6 for repair and maintenance, replenish the cleaning fluid 631, and clean and replace the small semi-cylinder 613 and the large semi-cylinder 615.

[0049] In this embodiment, when the camera 14 captures a large number of people who need to take or return materials in front of the locomotive on-board intelligent material cabinet, the controller in the electric control box 4 controls the material management device 2 6 to operate. Specifically, it first controls the push-pull device 63 to push the slide box 62 out, and then turns on the visual camera 64 to capture the image below it. When the person passes the face recognition verification, opens the cabinet door 8, and pulls out a drawer 7 to take or return the material, there is no need to close the cabinet door 8. The next person can directly take or return the material. However, at a certain moment, only one drawer 7 is pulled out. The last person needs to close the cabinet door 8 before leaving after taking or returning the material. After a period of time, no one takes or returns the material in front of the on-board intelligent material cabinet, and the controller in the electric control box 4 The processor analyzes and processes the information captured by the visual camera 64 and the camera 14 when the cabinet door 8 is open for a long time, and then, based on the remaining material information in the drawer 7 retrieved by the material management device 1, comprehensively compares and analyzes to determine which materials each person has taken or returned during the long time when the cabinet door 8 is open, and then stores the material flow information in the memory and displays it on the touch screen 13. This design eliminates the trouble of frequently opening and closing the cabinet door 8, improves the material flow efficiency, simplifies the material management process, and avoids longer and longer queues in front of the locomotive on-board intelligent material cabinet. Of course, when the camera 14 captures that there is only one person taking or returning materials in front of the locomotive on-board intelligent material cabinet, the material management device 2 6 will not start and remain in standby mode.

[0050] In this embodiment, since the locomotive-mounted intelligent material cabinet is installed on the machine tool, unlike the clean working environment of a dust-free laboratory, the working environment on the locomotive is harsh. The material cabinet will be subjected to the vibration and impact of the locomotive during its travel, which will raise dust. The material cabinet is in a noisy environment with people coming and going and a lot of dust in the air. In addition, multiple drawers 7 are frequently pulled out and pushed back, and materials are taken away and returned, which causes the dust on the drawers 7 and materials to fly around, and eventually the lens 65 of the visual camera 64 is contaminated with dust, affecting the visual recognition accuracy. Therefore, it is necessary to wipe the lens 65 regularly to keep the lens 65 clean. Based on this, a cleaning device is provided in the slide 61 for automatically wiping the lens 65, eliminating the trouble of manually wiping the lens 65.

[0051] In this embodiment, if Figure 5-Figure 11 As shown, the cleaning device includes a linear motor 66, a liquid storage box 67, a vertical plate 68, and a rotating shaft 611. The linear motor 66 is arranged on the bottom surface of the slide cylinder 61, and the liquid storage box 67 is installed on the linear motor 66. The liquid storage box 67 is driven by the linear motor 66 to move in the slide cylinder 61 along the sliding direction of the slide box 62.

[0052] In this embodiment, if Figure 8As shown, the left and right ends of the liquid storage box 67 are fixedly mounted with upright plates 68, and the front and rear ends of a pair of upright plates 68 are fixedly mounted with shaft frames 69, as shown in FIG. Fig. 9 and Fig.11 As shown, a slide groove 610 is provided on the shaft frame 69, and a rotating shaft 611 is slidably installed in the slide groove 610. The rotating shaft 611 is located above the liquid storage box 67, and both ends of the rotating shaft 611 pass through the slide groove 610. The rotating shaft 611 slides in the slide groove 610 to change the height difference from the rotating shaft 611 to the liquid storage box 67. This design makes it easy to wipe the lens 65 wet first and then dry, ensuring that the surface of the lens 65 is clean and tidy, without dust, debris and liquid stains.

[0053] In this embodiment, if Figure 6-Figure 8 , Fig.10 As shown, both ends of the rotating shaft 611 are rotatably mounted with a ring 625, and the ring 625 is connected with an elastic rope 626 and a pull rope 628, and the elastic rope 626 is connected to a pin 627 on the liquid storage box 67 or the vertical plate 68, and the pull rope 628 is wound on a rope winding roller 630, and the rope winding roller 630 is mounted on the output shaft of the second motor 629, and the second motor 629 is fixedly connected to the vertical plate 68, and the second motor 629 drives the rope winding roller 630 to rotate forward to wind up the pull rope 628 and stretch the elastic rope 626, and bring The movable shaft 611 slides to the right to the right end of the slide groove 610, and the motor 2 629 drives the rope winding roller 630 to rotate in the opposite direction to unfold the pull rope 628. The stretched elastic rope 626 pulls the shaft 611 to slide to the left to the left end of the slide groove 610. The height difference between the right end of the slide groove 610 and the liquid storage box 67 of the shaft 611 is greater than the height difference between the left end of the slide groove 610 and the liquid storage box 67. This design makes it easy to wipe the lens 65 wet first and then dry, ensuring that the surface of the lens 65 is clean and tidy without dust, debris and liquid stains.

[0054] In this embodiment, if Figure 6-Figure 8 , Fig.10 As shown, both ends of the rotating shaft 611 are coaxially fixedly installed with a driven wheel 617, the liquid storage box 67 is provided with a motor 618 and a sliding hole 621, the motor 618 is installed with a driving wheel 619, a slider 622 is slidably installed in the sliding hole 621, and a tensioning wheel 624 is rotatably installed on the slider 622. The tensioning wheel 624, the driving wheel 619 and the driven wheel 617 are tightly sleeved with a transmission belt 620, and the slider 622 is connected with a spring 623, and the spring 623 is connected to the liquid storage box 67 or the vertical plate 68. The spring 623 pulls the slider 622 to slide in the sliding hole 621 to make the tensioning wheel 624 tension the transmission belt 620, so that the motor can smoothly drive the driven wheel 617 to drive the rotating shaft 611 to rotate, and is not affected by the sliding of the rotating shaft 611 in the slide groove 610.

[0055] In this embodiment, if Figure 5-Figure 11 As shown, a small semi-cylindrical roller 612 and a large semi-cylindrical roller 614 are coaxially fixedly installed in the middle of the rotating shaft 611, a small semi-cylindrical roller 613 is coaxially detachably fixedly installed on the outer circumference of the small semi-cylindrical roller 612, and a large semi-cylindrical roller 615 is coaxially detachably fixedly installed on the outer circumference of the large semi-cylindrical roller 614. The small semi-cylindrical roller 613 and the large semi-cylindrical roller 615 are equidistant from the two ends of the rotating shaft 611, the small semi-cylindrical roller 613 and the large semi-cylindrical roller 615 are not in direct contact, and the large semi-cylindrical roller 613 is detachably fixedly installed on the outer circumference of the large semi-cylindrical roller 614. 14 is fixedly mounted with a water baffle 616, the water baffle 616 is located between the small semi-cylinder 613 and the large semi-cylinder 615, and is used to prevent the liquid on the large semi-cylinder 615 from flowing onto the small semi-cylinder 613. This design facilitates the lens 65 to be wiped wet first and then dry, ensuring that the surface of the lens 65 is clean and tidy without dust, debris and liquid stains. The rotation of the rotating shaft 611 drives the small semi-cylinder 613 and the large semi-cylinder 615 to alternately enter the liquid storage box 67; the liquid storage box 67 contains a cleaning liquid 631, such as Fig. 9 As shown, during the rotation of the rotating shaft 611, the large semi-cylinder 615 contacts with the cleaning liquid 631, and the small semi-cylinder 613 does not contact with the cleaning liquid 631. The small semi-cylinder 613 and the large semi-cylinder 615 are both made of water-absorbing materials. With this design, the large semi-cylinder 615 contacts with the cleaning liquid 631 to absorb the cleaning liquid 631, and then the large semi-cylinder 615 is used to wet-wipe the lens 65, and the small semi-cylinder 613 does not contact with the cleaning liquid 631, and the small semi-cylinder 613 can be used to dry-wipe the lens 65, thereby ensuring that the surface of the lens 65 is clean and tidy, free of dust, debris and liquid stains, and ensuring the wiping effect of the lens 65.

[0056] Specifically, Figure 6As shown, when the rotating shaft 611 is at the left end of the slide groove 610 and the small semi-cylinder 613 is located below the large semi-cylinder 615, the push-pull device 63 drives the visual camera 64 to move right into the slide cylinder 61. During the process, the upper end of the large semi-cylinder 615 rubs against the lens 65 at the lower end of the visual camera 64 to wet-wipe the lens 65 to wipe off the floating dust and stubborn stains on the lens 65; after the visual camera 64 enters the slide cylinder 61 and resets, the control motor 2 629 pulls the rotating shaft 611 to the right end of the slide groove 610 through the pull rope 628, and then controls the motor 1 618 to drive the rotating shaft 611 to rotate so that the small semi-cylinder 613 is located above the large semi-cylinder 615, and then controls the linear motor 66 to drive the liquid storage box 67 to the right. The movement makes the upper end of the small semi-cylinder 613 come into frictional contact with the lens 65 to dry-wipe the lens 65, wipe off the liquid stains on the lens 65, and ensure that the surface of the lens 65 is clean and tidy; after the liquid storage box 67 moves to the right end of the linear motor 66, the dry wiping of the lens 65 by the small semi-cylinder 613 is completed. At this time, the control motor 2 629 unfolds the pull rope 628 to move the rotating shaft 611 to the left end of the slide groove 610. At this time, the small semi-cylinder 613 is located above the large semi-cylinder 615, and the highest point of the small semi-cylinder 613 is lower than the lowest point of the lens 65. In the subsequent process of the linear motor 66 driving the liquid storage box 67 to move to the left and reset, the upper end of the small semi-cylinder 613 does not come into frictional contact with the lens 65.

[0057] Furthermore, during the process of the large semi-cylinder 615 frictionally contacting the lens 65 at the lower end of the visual camera 64 to wet-wipe the lens 65, the rotating shaft 611 can be controlled to rotate so that different parts of the large semi-cylinder 615 wet-wipe the lens 65 to improve the wet-wiping effect and ensure that the floating dust and stubborn stains on the lens 65 are wiped off.

[0058] In this embodiment, the floating dust and stubborn stains wiped off by the large semi-cylinder 615 are insoluble in the cleaning liquid 631. In the subsequent process in which the large semi-cylinder 615 is repeatedly rotated and immersed in the cleaning liquid 631 driven by the rotating shaft 611, with the help of the beating of the liquid, the floating dust and stubborn stains on the large semi-cylinder 615 will enter the cleaning liquid 631 and sink to the bottom of the liquid storage box 67 and separate from the large semi-cylinder 615, so as to ensure the cleanliness of the large semi-cylinder 615.
