Description

Technical Field

[0001] The present invention relates to the technical field of automobile production and processing, and particularly to a rotary protection device for a 3D vision positioning camera of an automobile body. Background Art

[0002] In a robot automated gluing project, a skid is used to realize the automatic transmission of the vehicle body on the production line. Due to the error of the transmission system, the vehicle body cannot stop at exactly the same orientation every time, that is, there may be a deviation in the vehicle body coordinate system. The 3D vision system uses 4 calibrated cameras to collect images of 4 parts of the vehicle body from 4 angles, and searches for the two-dimensional image coordinates of the inherent feature holes on the vehicle body from these images; at the same time, according to the orientation relationship between each camera and the coordinates of the feature holes in the vehicle body coordinate system, a best vehicle body orientation is determined mathematically, and the correction vector (X, Y, Z, RX, RY, RZ) between the current orientation and the theoretical orientation, that is, the deviation of the current orientation of the vehicle body, is calculated. The vision system transmits the correction vector to the robot through the PLC, so that the robot can accurately find the vehicle body and execute the corresponding gluing track.

[0003] At present, after the camera of the 3D vision system is calibrated, in order to prevent the camera lens from being polluted by glue mist and the camera vision from shifting due to human collision with the camera component, an air-operated protection flap is usually added to the camera lens, and a protective cover is added outside the camera component.

[0004] The air-operated protection flap is installed on the camera body. When the protection flap is opened and closed driven by the cylinder, the vibration may cause the movement of the fixed position of the camera, thus affecting the recognition of the feature holes on the vehicle body by the camera; after the air-operated protection flap is added to the camera lens, a protective cover still needs to be installed outside the camera component. The air-operated protection flap and the protective cover are separately installed, which increases the on-site installation time and raises the labor cost. Summary of the Invention

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to the attached Figure 1 and Figure 3, an embodiment of the present invention provides a rotary protection device for a 3D vision positioning camera of an automobile body, including a base 1. A protective barrel 2 is fixedly connected to the top of the base 1. The protective barrel 2 provides a strong external protection for the camera, can effectively resist external impacts and dust, extend the service life of the device. A protective mechanism 3 is arranged at the top of the protective barrel 2. The protective mechanism 3 controls the opening and closing of the rotary cover 302 through a pneumatic rotary table 301 to realize automatic protection of the camera lens and ensure protection from pollution in the non-working state.

[0031] A camera mechanism 4 is installed on the top of the base 1. Through a flexible connecting platform 401 and a rotating structure design, the camera mechanism 4 can achieve precise adjustment of angles and positions to meet different shooting requirements. A driving mechanism 5 is fixedly connected to the inner wall of the base 1. The driving mechanism 5 drives a rotating disk 504 through a motor two 501, enabling the protective barrel 2 to be quickly positioned or removed, improving the maintenance efficiency.

[0032] A positioning mechanism 6 is arranged on the top of the base 1. Through the sliding cooperation of a plurality of slide rails 601 and sliders 602, the positioning mechanism 6 ensures the stable positioning of the protective barrel 2 in the working state, avoiding affecting the working accuracy of the camera due to vibration. A connecting mechanism 7 is fixedly connected to the right end of the protective barrel 2. Through the elastic design of a spring 704 and a rubber pad 705, the connecting mechanism 7 ensures the airtightness between the air pipe and the device and prevents gas leakage.

[0033] Specifically, the pneumatic rotary table 301 is driven by a pneumatic control system to control the opening and closing of the rotary cover 302 to protect the camera lens from pollution. The camera mechanism 4 realizes position and angle adjustment through the connecting platform 401 to meet shooting requirements. The driving mechanism 5 drives the rotating disk 504 through the motor two 501 to realize the quick positioning or disassembly of the protective barrel 2. The positioning mechanism 6 ensures the stable operation of the protective barrel 2 through the cooperation of the slide rails 601 and the sliders 602. The connecting mechanism 7 uses the spring 704 and the rubber pad 705 to ensure the airtightness between the air pipe and the device and prevent gas leakage.

[0034] Please refer to the attached Figure 2 and Figure 8 , an air control assembly 8 is arranged on one side of the protective barrel 2. The protective mechanism 3 includes a pneumatic rotary table 301. The outside of the pneumatic rotary table 301 is fixedly connected to the top of the protective barrel 2. The pneumatic rotary table 301 provides stable rotary power, and the rotary speed and angle can be precisely controlled by adjusting the air supply pressure.

[0035] The outside of the pneumatic rotary table 301 is fixedly connected with a rotary cover 302. When the rotary cover 302 is opened, it is convenient for the camera to photograph the body feature holes. When it is closed, it effectively blocks the pollution of the glue mist to the lens. The camera mechanism 4 includes a connecting platform 401. The bottom of the connecting platform 401 is installed on the top of the base 1. The connecting platform 401 provides a flexible installation foundation for the camera, and its structural stability ensures that the shooting accuracy is not affected by vibration.

[0036] Please refer to the appendix Figure 2 and Figure 3 Inside the inner wall of the connecting platform 401, a first motor 402 is fixedly connected. The first motor 402 drives the rotating rod 403 to adjust the angle of the camera assembly, making the shooting perspective more diverse. The driving end of the first motor 402 is fixedly connected with the rotating rod 403. The rotating rod 403 can accurately rotate to adjust the position of the camera to meet the requirements of different shooting tasks. Two first buckles 404 are detachably connected to the outside of the rotating rod 403. The modular design of the first buckles 404 facilitates the quick replacement or adjustment of the camera assembly and improves the equipment maintenance efficiency.

[0037] One side of the first buckle 404 is fixedly connected with a second buckle 405. The second buckle 405 cooperates with the fastening buckle 407 to achieve the stable installation and precise adjustment of the camera 408. The inner wall of the second buckle 405 is detachably connected with an adjusting rod 406. The detachable design of the adjusting rod 406 enables the quick replacement of the camera 408 to meet the application requirements of different devices. The outside of the adjusting rod 406 is detachably connected with a fastening buckle 407. The fastening buckle 407 ensures that the camera remains stable under various complex working conditions and prevents deviation caused by vibration. The camera 408 is installed outside the fastening buckle 407, and the installation position of the camera 408 can be adjusted according to actual needs to capture the images of the key feature holes on the vehicle body.

[0038] Specifically, the pneumatic control component 8 controls the pneumatic rotary table 301 to drive the opening and closing of the rotary cover 302 to protect the camera lens from pollution and support shooting. The camera mechanism 4 drives the rotating rod 403 through the first motor 402 to adjust the camera angle. The first buckles 404 and the second buckles 405 cooperate to achieve the stable installation and flexible adjustment of the camera 408, ensuring accurate shooting perspective and meeting the requirements of different tasks.

[0039] Please refer to the appendix Figures 4 to 6 The driving mechanism 5 includes a second motor 501. The outside of the second motor 501 is fixedly connected to the inner wall of the base 1. The second motor 501 accurately drives the driving gear 502 to achieve the smooth operation of the rotating disk 504 and ensure the smooth operation of the equipment. The driving end of the second motor 501 is fixedly connected with the driving gear 502. The meshing connection between the driving gear 502 and the driven gear 503 ensures the efficient transmission of power and improves the equipment operation efficiency.

[0040] The inner wall of the base 1 is rotatably connected with a driven gear 503. The driven gear 503 works integrally with the rotating disc 504 to drive the positioning mechanism 6 to achieve precise moving positioning. The top of the driven gear 503 is fixedly connected with a rotating disc 504. The rotating disc 504 rotates smoothly through the gear transmission system and controls the action of the positioning mechanism 6 through cooperation with the chute 505, enabling the device to flexibly adjust the working position. A plurality of chutes 505 are provided on the top circumference of the rotating disc 504. The chute 505 is designed as an annular structure, which can accommodate the sliding of the extension column 603 to ensure the precise movement of the positioning block 604, thereby realizing the stable positioning of the protection barrel 2. The positioning mechanism 6 includes a plurality of slide rails 601. The plurality of slide rails 601 are fixedly connected to the inner wall of the base 1 in a circular pattern. The slide rails 601 provide a stable sliding track for the slider 602, reducing the friction and resistance during the movement of the positioning block 604 and improving the operation precision of the device.

[0041] The top of the slide rail 601 is slidably connected with a slider 602. The slider 602 slides smoothly on the slide rail 601 and transmits the displacement through the extension column 603 to realize the movement of the positioning block 604, ensuring the flexible positioning ability of the device. One side of the slider 602 is fixedly connected with an extension column 603. The extension column 603 transmits the movement of the slider 602 into the chute 505 and at the same time serves as a support component to ensure the stability of the positioning block 604, improving the overall reliability of the device. The bottom of the extension column 603 is slidably connected to the inner wall of the chute 505. The extension column 603 realizes the synchronous movement of the positioning mechanism 6 through cooperation with the chute 505, providing convenience for the quick installation and disassembly of the device.

[0042] The top of the slider 602 is fixedly connected with a positioning block 604. The positioning block 604 precisely positions the protection barrel 2 through movement. Its independent movable design facilitates the maintenance and replacement of the device. On the adjacent sides of the two positioning blocks 604, a cylinder 605 is fixedly connected. The cylinder 605 provides a power source for the clamping block 606 and realizes the stable fixation of the connecting table 401 by driving the clamping block 606 to move. The driving end of the cylinder 605 is fixedly connected with a clamping block 606. The clamping block 606 clamps the connecting table 401 through movement, thereby ensuring the stability of the camera mechanism 4 during operation and avoiding affecting the shooting effect due to vibration. The top of the base 1 is fixedly connected with a fixed seat 608. The fixed seat 608 supports the entire camera mechanism 4 through a stable structure and provides a stable basis for the operation of the cylinder 605 and the clamping block 606.

[0043] On the top of the base 1, there are multiple grooves 607. The grooves 607 are designed to accommodate the movement of the slider 602, prevent the external displacement of the slider 602 from affecting the positioning accuracy, and improve the running stability of the entire device. The outer part of the slider 602 is slidably connected to the inner wall of the groove 607. The sliding connection between the slider 602 and the groove 607 effectively prevents the occurrence of offset phenomena, enabling the device to maintain high stability and accuracy during operation. The adjacent sides of the two clamping blocks 606 are in contact with the outside of the connecting platform 401. The clamping blocks 606 are in contact with the connecting platform 401 to accurately fix the camera assembly, further enhancing the stability of the device during the shooting process.

[0044] The bottom of the positioning block 604 is slidably connected to the top of the base 1. The positioning block 604 ensures accurate movement trajectories through the bottom sliding connection, reduces the frictional resistance during movement, and improves the durability of the device.

[0045] Specifically, the motor 501 drives the driving gear 502 and the driven gear 503 to drive the rotating disk 504 to rotate, realizing the linkage between the sliding groove 505 and the positioning mechanism 6. The sliding groove 505 accommodates the sliding of the extension column 603. The slider 602 is connected through the extension column 603 to move the positioning block 604, ensuring the accurate positioning and flexible disassembly of the protective barrel 2. The slide rail 601 of the positioning mechanism 6 cooperates with the slider 602 to provide a smooth sliding trajectory, reducing friction and improving the operation accuracy. The air cylinder 605 drives the clamping block 606 to move, fixing or releasing the connecting platform 401 to ensure the stability of the camera mechanism 4. The groove 607 on the top of the base 1 provides a restriction for the movement of the slider 602 to prevent offset. The overall design ensures the stable, efficient operation and easy maintenance of the device.

[0046] Please refer to the attached Figure 7 As shown in the figure, the connecting mechanism 7 includes a connecting sleeve 701. The left end of the connecting sleeve 701 is fixedly connected to the right end of the protective barrel 2. The connecting sleeve 701 provides an interface for the gas pipeline through a stable installation method, ensuring the smooth access of external gas supply. A threaded block 702 is fixedly connected to the inner wall of the connecting sleeve 701. The threaded block 702 is designed as a standard threaded interface, which can tightly connect the external air pipe, avoid air leakage, and improve the overall sealing performance. A limiting block 703 is slidably connected to the inner wall of the connecting sleeve 701. The limiting block 703 adapts to the connection of air pipes with different diameters through the sliding structure and tightly limits the air pipe under the action of the spring 704.

[0047] One end of the limiting block 703 is fixedly connected with a spring 704. The spring 704 stores elastic potential energy through deformation and provides a strong reverse force when loosening, effectively improving the stability of the trachea connection. The other end of the limiting block 703 is fixedly connected with a rubber pad 705. The rubber pad 705 further improves the pipeline sealing performance by using its flexible material, prevents gas leakage, and enhances the reliability of the device. One end of the spring 704 away from the limiting block 703 is fixedly connected to the inner wall of one side of the connecting sleeve 701. The fixed structure of the spring 704 provides a stable fulcrum for the reverse force, making the trachea connection more firm and suitable for long-term frequent use. The pneumatic control component 8 includes a mounting plate 801. The outside of the mounting plate 801 is mounted on the outside of the protective barrel 2. The modular design of the mounting plate 801 facilitates rapid assembly and disassembly, providing flexible mounting options for the pneumatic control component 8.

[0048] Please refer to the appendix Figure 3 and Figure 8 . One side of the mounting plate 801 is fixedly connected with a solenoid valve 802. The solenoid valve 802 controls the air flow direction to achieve precise operation of the pneumatic rotary table 301, thereby ensuring the reliable opening and closing of the rotary cover 302. One side of the mounting plate 801 is fixedly connected with an air pressure regulator 803. The air pressure regulator 803 ensures stable operation of the device by adjusting the supply air pressure and adapts to the requirements of different working environments at the same time. Through holes are opened on both sides of the bottom of the fixed seat 608. The outside of the clamping block 606 is slidably connected to the inner wall of the through hole. The design of the through hole provides a smooth path for the movement of the clamping block 606, enabling the clamping block 606 to precisely fix the connecting table 401.

[0049] Specifically, a stable gas pipeline interface is provided through the connecting sleeve 701. The internal threaded block 702 is tightly connected with the external trachea, avoiding air leakage and improving the sealing performance. The limiting block 703 realizes the stable limit of the trachea through the spring 704. The rubber pad 705 further enhances the sealing performance. The spring 704 stores elastic potential energy through deformation and provides a stable reverse force to ensure the firm connection of the trachea. The mounting plate 801 of the pneumatic control component 8 supports modular assembly. The solenoid valve 802 precisely controls the air flow direction and drives the pneumatic rotary table 301 to operate the opening and closing of the rotary cover 302. The air pressure regulator 803 adjusts the supply air pressure to ensure the stable operation of the device under various working conditions. The through hole design of the fixed seat 608 provides a path for the movement of the clamping block 606 to achieve precise fixation of the connecting table 401. The overall design improves the sealing performance, operation accuracy and adaptability of the device.

[0050] Working principle: When the device needs to be used, an external air hose is connected through the connecting mechanism 7. At this time, by pushing the rubber pad 705, the rubber pad 705 drives the limiting block 703 to move. The movement of the limiting block 703 can squeeze the spring 704, causing the spring 704 to deform and store elastic potential energy. At this time, the pipe is screwed into the inner wall of the thread block 702, and then under the driving force of the spring 704, the rubber pad 705 presses against the pipe to improve the sealing effect between the pipes; among them, the mounting plate 801 can be assembled modularly, and only overall fixation is required on site. The air pressure regulator 803 is used to adjust the supply air pressure, and the solenoid valve 802 is used to control the supply air direction of the pneumatic rotating table 301, thereby controlling the opening and closing of the rotating cover 302. Then, the solenoid valve 802 controls the pneumatic rotating table 301 to rotate, so that the pneumatic rotating table 301 drives the rotating cover 302 to rotate, and the protective barrel 2 can be opened and closed. When the rotating cover 302 is opened, it is convenient for the camera to take pictures of the body feature holes. When the rotating cover 302 is closed, it can prevent the glue mist from contaminating the camera lens during automatic robot gluing;

[0051] By starting the first motor 402, the rotating rod 403 can be driven to rotate, so that the first buckle 404 drives the second buckle 405 to rotate, and finally the camera 408 can be driven to rotate, and the angle can be adjusted as needed. The position of the camera 408 is further adjusted by the second buckle 405 and the fastening buckle 407;

[0052] When maintenance and repair of the internal equipment are required, by starting the second motor 501, the second motor 501 can drive the driving gear 502 to rotate when it starts. At this time, the driving gear 502 meshes with the driven gear 503, so that the driven gear 503 rotates. During the rotation of the driven gear 503, the rotating disk 504 can be driven to rotate. At this time, the rotation of the rotating disk 504 will cause the sliding groove 505 to move. At this time, the extension column 603 will move on the inner wall of the sliding groove 505. By the movement of the extension column 603, the slider 602 can be controlled to slide on the top of the slide rail 601. By the movement of the slider 602, the positioning block 604 can be driven to move. Finally, under the movement of the positioning block 604, the positioning of the protective barrel 2 can be cancelled, so that the protective barrel 2 can be taken out. Then, by starting the cylinder 605, the clamping block 606 can be driven to move when the cylinder 605 starts, so that the fixation of the connecting table 401 can be cancelled, and the camera mechanism 4 can be removed to adjust the components in the camera mechanism 4.

[0053] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
