Description

Technical Field

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

[0002] In the robot automated gluing project, the car body is automatically conveyed on the production line through a skid. Due to the error of the conveying system, the car body cannot stop at exactly the same position every time, that is, the car body coordinate system may have a deviation. The 3D vision system uses 4 calibrated cameras to collect images of 4 parts of the car body from 4 angles, and searches for the 2D image coordinates of the inherent characteristic holes on the car body from these images; at the same time, according to the position relationship between each camera and the coordinates of the characteristic holes in the car body coordinate system, an optimal car body position is mathematically determined, and the correction vector (X, Y, Z, RX, RY, RZ) between the current position and the theoretical position is calculated, that is, the deviation of the current position of the car body. The vision system transmits the correction vector to the robot through the PLC, so that the robot can accurately find the car body and execute the corresponding gluing track.

[0003] Currently, after the camera of the 3D vision system is calibrated, in order to prevent glue mist from contaminating the camera lens and human collision with the camera component causing the camera field of view to shift, thereby affecting the camera's recognition of the characteristic holes in the vehicle body, a pneumatic protective flap is usually added to the camera lens and a protective cover is added to the outside of the camera component.

[0004] The pneumatic protective flap is installed on the camera body. When the protective flap is opened and closed by the cylinder, vibration may cause the camera's fixed position to move, thereby affecting the camera's recognition of the characteristic holes in the vehicle body. After the camera lens is equipped with a pneumatic protective flap, a protective cover still needs to be installed on the outside of the camera assembly. The pneumatic protective flap and the protective cover are installed separately, which increases the on-site installation time and increases labor costs. Summary of the invention

[0029] Specifically, the pneumatic rotating table 301 is controlled by the pneumatic control component 8 to drive the rotating cover 302 to open and close, thereby protecting the camera lens from contamination and supporting shooting. The camera mechanism 4 drives the rotating rod 403 through the motor 1 402 to adjust the camera angle, and the buckle 1 404 and the buckle 2 405 cooperate to achieve stable installation and flexible adjustment of the camera 408, ensuring accurate shooting angle and meeting different task requirements.

[0030] Please refer to the attached 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, thereby ensuring the smooth operation of the equipment. The driving end of the second motor 501 is fixedly connected to 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 operation efficiency of the equipment.

[0031] The inner wall of the base 1 is rotatably connected to a driven gear 503, and the driven gear 503 works in an integrated manner with the rotating disk 504 to drive the positioning mechanism 6 to achieve precise mobile positioning; the top of the driven gear 503 is fixedly connected to the rotating disk 504, and the rotating disk 504 achieves smooth rotation through a gear transmission system, and controls the movement of the positioning mechanism 6 by cooperating with the slide groove 505, so that the equipment can flexibly adjust the working position, and a plurality of slide grooves 505 are opened on the top circumference of the rotating disk 504. The slide groove 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 achieving stable positioning of the protective barrel 2, and the positioning mechanism 6 includes a plurality of slide rails 601, and the plurality of slide rails 601 are fixedly connected to the inner wall of the base 1 circumferentially, and the slide rails 601 provide a stable sliding trajectory for the slider 602, thereby reducing the friction and resistance during the movement of the positioning block 604 and improving the accuracy of equipment operation.

[0032] The top of the slide rail 601 is slidably connected to a slider 602, which slides smoothly on the slide rail 601 and transfers displacement through an extension column 603 to achieve movement of the positioning block 604, thereby ensuring the flexible positioning capability of the device. One side of the slider 602 is fixedly connected to an extension column 603, which transfers the movement of the slider 602 to the inside of the slide groove 505 and simultaneously serves as a supporting component to ensure the stability of the positioning block 604 and improve the overall reliability of the device. The bottom of the extension column 603 is slidably connected to the inner wall of the slide groove 505, and the extension column 603 cooperates with the slide groove 505 to achieve synchronous movement of the positioning mechanism 6, thereby providing convenience for rapid installation and disassembly of the device.

[0033] The top of the slider 602 is fixedly connected to a positioning block 604, which can accurately position the protective barrel 2 by moving. Its independent movable design facilitates the maintenance and replacement of the equipment. The adjacent sides of the two positioning blocks 604 are fixedly connected to a cylinder 605, which provides a power source for the clamping block 606, and drives the clamping block 606 to move to achieve stable fixation of the connecting platform 401. The driving end of the cylinder 605 is fixedly connected to the clamping block 606, which clamps the connecting platform 401 by moving, thereby ensuring the stability of the camera mechanism 4 during operation and avoiding vibration that affects the shooting effect. The top of the base 1 is fixedly connected to a fixing seat 608, which supports the entire camera mechanism 4 through a stable structure and provides a stable foundation for the operation of the cylinder 605 and the clamping block 606.

[0034] A plurality of grooves 607 are provided on the top of the base 1. The grooves 607 are designed to accommodate the movement of the slider 602 to prevent the external displacement of the slider 602 from affecting the positioning accuracy and to improve the running stability of the entire device. The external sliding connection of the slider 602 is 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 the offset phenomenon, so that the device maintains a 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 achieve precise fixation of the camera assembly by contacting the connecting platform 401, thereby further improving the stability of the device during shooting.

[0035] The bottom of the positioning block 604 is slidably connected to the top of the base 1. The positioning block 604 ensures the accuracy of the movement trajectory through the bottom sliding connection, while reducing the friction resistance during the movement and improving the durability of the equipment.

[0036] Specifically, the driving gear 502 and the driven gear 503 are driven by the motor 2 501 to drive the rotating disk 504 to rotate, thereby realizing the linkage between the slide groove 505 and the positioning mechanism 6. The slide groove 505 accommodates the sliding of the extension column 603, and the slider 602 is connected through the extension column 603 to move the positioning block 604 to ensure 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, reduce friction and improve operational accuracy. The cylinder 605 drives the clamping block 606 to move, fix or release the connecting platform 401, and ensure the stability of the camera mechanism 4. The groove 607 on the top of the base 1 provides a limit for the movement of the slider 602 to prevent deviation. The overall design ensures stable and efficient operation of the equipment and is easy to maintain.

[0037] Please refer to the attached Figure 7 The connecting mechanism 7 includes a connecting sleeve 701, the left end of which 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 to ensure smooth access to the external gas supply. The inner wall of the connecting sleeve 701 is fixedly connected with a threaded block 702. The threaded block 702 is designed as a standard threaded interface, which can be tightly connected to the external air pipe to avoid air leakage and improve the overall sealing performance. The inner wall of the connecting sleeve 701 is slidably connected with a limiting block 703. The limiting block 703 adapts to the connection of air pipes of different diameters through a sliding structure, and tightly limits the air pipe under the action of a spring 704.

[0038] One end of the limiting block 703 is fixedly connected to a spring 704. The spring 704 stores elastic potential energy through deformation, provides a strong reverse force when loosened, and effectively improves the stability of the air pipe connection. The other end of the limiting block 703 is fixedly connected to a rubber pad 705. The rubber pad 705 uses its flexible material to further improve the sealing of the pipeline, prevent gas leakage, and enhance the reliability of the equipment. The 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 reaction force fulcrum, making the air pipe connection more secure and suitable for long-term and frequent use. The air control component 8 includes a mounting plate 801. The outside of the mounting plate 801 is installed on the outside of the protective barrel 2. The mounting plate 801 is easy to quickly assemble and disassemble through modular design, providing flexible installation options for the air control component 8.

[0039] Please refer to the attached Figure 3 and Figure 8 A solenoid valve 802 is fixedly connected to one side of the mounting plate 801. The solenoid valve 802 controls the direction of the airflow to achieve precise operation of the pneumatic rotating table 301, thereby ensuring the reliable opening and closing of the rotating cover 302. An air pressure regulator 803 is fixedly connected to one side of the mounting plate 801. The air pressure regulator 803 ensures stable operation of the equipment by adjusting the air supply pressure, while adapting to different working environment requirements; through holes are opened on both sides of the bottom of the fixed seat 608, and 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, so that the clamping block 606 can accurately fix the connecting table 401.

[0040] Specifically, a stable gas pipeline interface is provided through the connecting sleeve 701, and the built-in threaded block 702 is tightly connected with the external air pipe to avoid air leakage and improve the sealing performance. The limiting block 703 realizes the stable limitation of the air pipe through the spring 704, and 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 that the air pipe is firmly connected. The mounting plate 801 of the air control component 8 supports modular assembly, and the solenoid valve 802 accurately controls the direction of the air flow and drives the pneumatic rotating table 301 to operate the opening and closing of the rotating cover 302. The air pressure regulator 803 adjusts the air supply pressure to ensure that the equipment operates stably 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, operating accuracy and adaptability of the equipment.

[0041] Working principle: when the equipment needs to be used, an external air hose is connected from the connecting mechanism 7. At this time, the rubber pad 705 is pushed so that the rubber pad 705 drives the limiting block 703 to move. The movement of the limiting block 703 can squeeze the spring 704 so that the spring 704 is deformed to store elastic potential energy. At this time, the pipe is twisted so that the pipe thread enters the inner wall of the threaded block 702. Then, the rubber pad 705 is pressed against the pipe by the pushing force of the spring 704 to improve the sealing effect between the pipes. The mounting plate 801 can be assembled modularly. The field only needs to be fixed as a whole. The air pressure regulator 803 is used to adjust the air supply pressure. The solenoid valve 802 is used to control the air supply direction of the pneumatic rotating table 301, thereby controlling the opening and closing of the rotating cover 302. Then, the pneumatic rotating table 301 is controlled to rotate by the solenoid valve 802, so that the pneumatic rotating table 301 drives the rotating cover 302 to rotate, and the protective barrel 2 can be opened and closed. The rotating cover 302 is opened to facilitate the camera to take pictures of the characteristic holes of the vehicle body. The rotating cover 302 is closed to prevent the glue mist from polluting the camera lens when the robot automatically applies glue; The motor 1 402 is started to drive the rotating rod 403 to rotate, so that the buckle 1 404 drives the buckle 2 405 to rotate, and finally drives the camera 408 to rotate, and the angle can be adjusted as needed, and the position of the camera 408 can be further adjusted through the buckle 2 405 and the fastening buckle 407; When it is necessary to inspect and maintain the internal equipment, by starting the motor 2 501, the starting of the motor 2 501 can drive the active gear 502 to rotate. At this time, the active gear 502 meshes with the driven gear 503, so that the driven gear 503 rotates, and the driven gear 503 can drive the rotating disk 504 to rotate during the rotation. At this time, the rotation of the rotating disk 504 will cause the slide 505 to move. At this time, the extension column 603 will move on the inner wall of the slide 505. The movement of the extension column 603 can control the slider 602 to slide on the top of the slide rail 601. The movement of the slider 602 can drive the positioning block 604 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, and then the cylinder 605 is started. Under the start of the cylinder 605, the clamping block 606 can be driven to move, so that the fixation of the connecting platform 401 can be cancelled, so that the camera mechanism 4 can be removed and the components in the camera mechanism 4 can be adjusted.
