Description

Technical Field

[0001] This invention relates to the field of grinding and polishing technology, specifically to a grinding machine for one-piece metal plates based on machine vision. Background Technology

[0002] The main purpose of polishing unibody metal panels is to improve surface quality and enhance product performance. By removing burrs, oxide scale, welding marks, and other impurities from the surface of the metal panel, the surface becomes smoother and more uniform, which is beneficial for the adhesion and effect of subsequent coatings, paints, or other surface treatment processes. In addition, polishing can also eliminate surface defects, improve the appearance and feel of the metal panel, and extend its corrosion resistance and service life.

[0003] For example, a metal plate grinding and polishing machine with publication number CN113857990A includes a transmission device, multiple sets of pressure plate devices spanning the transmission surface of the transmission device, a first grinding device and a second grinding device above the transmission device; it also includes a first lifting device and a second lifting device for driving the height of the first grinding device and the second grinding device respectively; the first grinding device includes a driven roller, a driving roller and a tension roller arranged in a triangular structure, a closed sanding belt passing through the outer peripheral wall of the driven roller, the driving roller and the tension roller, a motor for driving the driving roller to rotate, a grinding roller that can move longitudinally between the driven roller and the driving roller, and a spring buffer assembly connected to the grinding roller.

[0004] However, the lack of a flipping function in existing technologies severely limits the efficiency and quality of surface treatment of integrated metal panels. First, it is impossible to fully process both sides or multiple sides of the metal panel, resulting in only single-sided operation, which increases the number of processes and manual handling, and reduces production efficiency. Second, the inability to automatically flip makes the operation process cumbersome and time-consuming, increases human error and safety risks, and affects processing consistency and product quality. In addition, the lack of a flipping function makes it difficult to grind and inspect the panel at different angles, limiting the applicability and flexibility of the equipment and making it difficult to meet complex processing needs. Summary of the Invention

[0005] The purpose of this invention is to provide a machine vision-based grinding machine for unibody metal sheets, in order to solve the problem mentioned in the background art that the lack of a flipping function severely limits the efficiency and quality of surface treatment of unibody metal sheets.

[0015] Preferably, the top center of the first mounting plate is fixedly connected to the bottom end of the cylinder, and a sliding rod is fixedly connected to the top of the first mounting plate, with the sliding rod slidably connected to the support frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the flipping plate is driven by a flipping rod to achieve the overall flipping of the metal plate. During the flipping process, the sliding block maintains stable linear and vertical sliding within the limit frame and track, ensuring accurate and smooth flipping, improving processing efficiency and consistency. To achieve visual monitoring and operational precision, an adjustable-angle camera mounting structure is provided. The camera direction is changed through the linkage of the second rotating rod and multiple sets of gears, expanding the monitoring field of view. When the camera direction needs to be adjusted independently, the first rotating rod can be operated to rotate the camera angle independently. During this process, a locking mechanism is used to prevent interference from other components, ensuring accurate camera adjustment.

[0017] 2. In this invention, the third drive motor drives the rotating rod to rotate, which in turn drives the rotating plate to start the rotating action. With the cooperation of the first and second sliding blocks, the metal plate can be smoothly rotated and polished on both sides. In terms of structural design, the setting of the limiting frame and the notch in the middle of the track provides room for the bidirectional rotation of the rotating rod, avoiding mechanical interference. At the same time, during the positioning of the metal plate, the threaded rod at the top of the locking frame rotates and drives its bottom end to apply pressure to the metal plate, achieving stable clamping and effective positioning. This not only ensures the processing accuracy but also improves the operating efficiency and the reliability of the equipment.

[0018] 3. In this invention, the second drive motor drives two lead screws to rotate via a belt assembly, thereby pushing the moving plate and the grinder upward. Combined with a cylinder and slide rod, the grinding height can be precisely controlled. During the movement of the grinder, the active bevel gear slides along the drive rod and is driven to rotate by the first drive motor. After meshing with the driven bevel gear, it drives the second lead screw to rotate, causing the moving block to slide within the moving plate. The trapezoidal structure ensures its stability and reliability. Through the coordinated action of the first and second drive motors, the grinder can be freely adjusted in height and translation direction, thus meeting the requirements for high-precision grinding of the surface of a one-piece metal plate. This improves operational flexibility and grinding effect. The structure is compact and possesses good adaptability and stability. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Refer to Figures 1-7 As shown: A machine vision-based grinding machine for a metal unibody plate includes a support frame 1, a cylinder 3 mounted at the top center of the support frame 1, a grinding mechanism 4 fixedly connected to the bottom of the cylinder 3, a flipping mechanism 5 mounted on one side of the bottom of the support frame 1, and two monitoring mechanisms 6 connected to the bottom of the grinding mechanism 4. The flipping mechanism 5 includes a base plate 56. A first limiting frame 53 and a second limiting frame 54 are fixedly connected to the top two sides of the base plate 56, respectively. A first sliding block 57 and a second sliding block 58 are slidably connected to the inner sides of the first limiting frame 53 and the second limiting frame 54. A second track 541 is fixedly connected to the top of the second limiting frame 54. The first track 531 is fixedly connected to the top of the first limiting frame 53. The two first sliding blocks 57 are slidably connected to the first track 531 and the second track 541, respectively. The monitoring mechanism 6 includes a frame 61, a central column 691 rotatably connected to the top center of the frame 61, a first driven gear 69 fixedly connected to the outer surface of the bottom end of the central column 691, a first rotating rod 63 rotatably connected to one side of the central column 691, and a second rotating rod 67 rotatably connected to the other side of the central column 691. A first driving gear 631 meshing with the first driven gear 69 is fixedly connected to the bottom end of the first rotating rod 63, and a second transmission gear 672 meshing with the first driven gear 69 is rotatably connected to the bottom end of the second rotating rod 67.

[0023] A first rotary motor 62, which is fixedly connected to the first rotating rod 63, is installed on one side of the inner cavity of the frame 61, and a second rotary motor 68, which is fixedly connected to the second rotating rod 67, is installed on the other side of the inner cavity of the frame 61. A rotating column 65 is fixedly connected to the top of the central column 691, and a rotating frame 64 is rotatably connected to the inner side of the rotating column 65.

[0024] A second driving bevel gear 66 is rotatably connected to the outer surface of the bottom end of the rotating column 65. A second driven gear 692 is fixedly connected to the bottom end of the second driving bevel gear 66. A second driving gear 671, which meshes with the second driven gear 692, is fixedly connected to the top end of the second rotating rod 67. A first transmission gear 632, which meshes with the second driven gear 692, is rotatably connected to the top end of the first rotating rod 63. A camera 641 is fixedly mounted on the top of the rotating frame 64, and a second driven bevel gear 642, which meshes with the second driving bevel gear 66, is fixedly connected to the rotating frame 64.

[0025] In this embodiment, during the surface polishing process of the integrated metal plate, the integrated metal plate must first be placed horizontally between two locking frames 55 to ensure its stability and the accuracy of the processing position. Driven by the flipping rod 52, the flipping plate 551 connected to it can rotate or swing. When the flipping plate 551 starts to move, it simultaneously drives the locking frames 55 connected to it to shift, thereby causing the integrated metal plate clamped between the locking frames 55 to flip.

[0026] During the flipping process, the two second sliding blocks 58 are located inside the first limiting frame 53 and the second limiting frame 54, respectively, and move horizontally along the linear guide rails set inside them, ensuring that the locking frame 55 maintains a stable path and does not deviate during flipping. At the same time, the two first sliding blocks 57 are in the first track 531 and the second track 541, respectively, and move vertically. This motion mechanism assists the locking frame 55 in completing the flipping process through vertical sliding, allowing the metal monolithic plate to be smoothly flipped to another surface, providing convenient conditions for subsequent grinding or processing, thereby significantly improving processing efficiency and surface treatment consistency.

[0027] To facilitate visual monitoring and ensure operational precision during the polishing process, an adjustable-angle and adjustable-position camera 641 mounting structure is also provided. When the viewing angle of the camera 641 needs to be adjusted, it can be rotated by driving the second rotating rod 67. The second rotating rod 67 is connected to the second driven gear 692. When rotated, the second driven gear 692 will rotate accordingly, driving the first transmission gear 632 meshing with it to rotate together.

[0028] At this time, the rotation of the first transmission gear 632 further drives the second driving bevel gear 66 to move, which in turn applies a driving force to the meshing second driven bevel gear 642. The second driven bevel gear 642 is fixedly connected to the rotating frame 64, so after being driven by rotation, it drives the entire rotating frame 64 to rotate. The rotation of the rotating frame 64 causes the camera 641 mounted on it to adjust its direction and angle synchronously, thereby expanding the monitoring field of view and improving the visualization monitoring range and operational accuracy of on-site operations.

[0029] Furthermore, if the rotation direction of the camera 641 needs to be adjusted independently, the first rotating rod 63 can be manipulated to drive the first driving gear 631 connected to it to rotate. The first driving gear 631 drives the first driven gear 69 to rotate through a meshing structure. The first driven gear 69 is linked with the central column 691, thereby causing the central column 691 and the rotating column 65 to rotate together. During this process, the second rotating rod 67 remains stationary. At this time, the second driven gear 692 connected to it does not participate in the movement, thus imposing a restriction on the first transmission gear 632, keeping it in a locked state to avoid interfering with the current independent rotation operation.

[0030] During this independent rotation phase, the rotating column 65 drives the rotating frame 64 to rotate. Simultaneously, since the rotating frame 64 is connected to the second driven bevel gear 642, this bevel gear also rotates. During this process, it experiences resistance or guiding force from the stationary second driving bevel gear 66, thus creating a dual adjustment effect for the angle and direction of the camera 641. This mechanism allows for precise control of the camera 641's viewing angle without changing the state of the rotating rod, effectively improving the adaptability and flexibility of the monitoring equipment in complex grinding environments.

[0031] Example 2: Figure 3 and Figure 4As shown, a fixing block 522 is fixedly connected to the top of the base plate 56. A third drive motor 51 is installed on one side of the fixing block 522, and a flipping rod 52, which is fixedly connected to the output end of the third drive motor 51, is rotatably connected to the inner side of the fixing block 522. A drive block 521 is fixedly connected to one end of the flipping rod 52. Two locking frames 55 are symmetrically arranged between the first limiting frame 53 and the second limiting frame 54. A flipping plate 551 is fixedly connected to the opposite side of each of the two locking frames 55. Multiple threaded rods 552 are threadedly connected to the top of the locking frame 55. The flipping plate 551 is rotatably connected to the second sliding block 58 and the first sliding block 57, respectively. One end of the flipping rod 52 is rotatably connected to one of the flipping plates 551.

[0032] In this embodiment, when the third drive motor 51 starts and drives the flipping rod 52 to rotate, the drive block 521 fixed on the flipping rod 52 moves synchronously, thereby driving the flipping plate 551 connected to one side of it to start moving along a preset trajectory. This structural design makes the flipping action more stable and reliable, effectively avoiding shaking and deviation during operation.

[0033] During the flipping process, the second sliding block 58 and the first sliding block 57 work together to drive the flipping of the integrated metal plate. The first sliding block 57 primarily serves as a guide and support, ensuring the stability of the metal plate during flipping, while the second sliding block 58 undertakes the active force transmission function, achieving efficient transmission of the flipping action. Through this collaborative mechanism, the integrated metal plate can be smoothly flipped from one side to the other, thereby achieving double-sided polishing and improving polishing efficiency and the surface quality of the finished product.

[0034] To ensure the smooth rotation of the flipping rod 52 during the flipping process, a notch structure is designed in the middle of the first limit frame 53 and the first track 531. The notch provides necessary room for the clockwise and counterclockwise rotation of the flipping rod 52, effectively avoiding jamming or mechanical conflict caused by structural interference during rotation, thereby ensuring the continuity and reliability of the overall operation.

[0035] During the positioning of the integrated metal plate, the threaded rod 552 located at the top of the locking frame 55 is rotated, causing the threaded rod 552 to move downwards. As the threaded rod 552 moves downwards, its bottom end applies a vertically downward clamping force to the integrated metal plate, thereby achieving a stable lock on the integrated metal plate. This positioning structure is not only easy to operate, but also effectively prevents the integrated metal plate from shifting during polishing, ensuring the stability of processing accuracy and quality.

[0036] Example 3: According to Figure 5 and Figure 8As shown, the grinding mechanism 4 includes a first mounting plate 41 and a first support block 411 fixedly connected to its bottom. Two first lead screws 45 are symmetrically rotatably connected to one side of the first support block 411. A movable plate 46 is threadedly connected to the outer surface of the two first lead screws 45, and a second lead screw 47 is rotatably connected to the inner side of the movable plate 46. A movable block 49, threadedly connected to the second lead screw 47, is slidably connected to the inner side of the bottom end of the movable plate 46. A second mounting plate 48 is fixedly connected to the bottom of the movable block 49, and a grinder 481 is fixedly connected to the center of the bottom of the second mounting plate 48. One end of each of the two first lead screws 45 is rotatably connected to a second support block 451 fixedly connected to the first mounting plate 41. A second drive motor 44 is mounted on one side of the bottom of the second support block 451. A belt drive assembly 441 is fixedly connected to the output end of the second drive motor 44, and the belt drive assembly 441 is fixedly connected to the two first lead screws 45 respectively. A drive rod 421 is rotatably connected to the bottom end of the first support block 411. A first driving bevel gear 43 is slidably connected to the surface of the drive rod 421 through a guide groove. The inner wall of the first driving bevel gear 43 is provided with a protrusion corresponding to the guide groove. A connecting frame 431, which is fixedly connected to the moving plate 46, is fixedly connected to the outer surface of the first driving bevel gear 43. A first driven bevel gear 471 is fixedly connected to the outer surface of one end of the second lead screw 47. The first driven bevel gear 471 meshes with the connecting frame 431. A first drive motor 42, which is fixedly connected to the drive rod 421, is mounted at the bottom of the first mounting plate 41. The top center of the first mounting plate 41 is fixedly connected to the bottom end of the cylinder 3, and a slide rod 2 is fixedly connected to the top of the first mounting plate 41. The slide rod 2 is slidably connected to the support frame 1.

[0037] In this embodiment, the belt drive assembly 441 is effectively started to operate by the driving action of the second drive motor 44. The belt drive assembly 441 is synchronously connected to the two first lead screws 45, so when the belt drive assembly 441 operates, it can simultaneously drive the two first lead screws 45 to rotate synchronously. As the first lead screw 45 rotates, its threaded structure moves relative to the movable plate 46 located outside it, causing the movable plate 46 to move smoothly along the lead screw axis. This action directly causes the grinder 481 mounted on the movable plate 46 to rise accordingly, thereby adjusting the grinding height of the metal plate to meet the grinding needs of different processing stages or different surface areas.

[0038] Furthermore, through precise control of cylinder 3, combined with the linear limiting function provided by slide bar 2, the height of polisher 481 in the vertical direction can be finely adjusted. This adjustment mechanism allows the operator to adjust the working height of polisher 481 in real time according to the undulations of the metal surface or the polishing requirements during the actual polishing process, thereby improving the accuracy and consistency of polishing.

[0039] As the moving plate 46 moves along the first lead screw 45, the first driving bevel gear 43, located inside the system, slides along the outer surface of the drive rod 421. The drive rod 421 has a longitudinal guide groove on its surface, which allows for a stable engagement with the protrusion structure embedded in the first driving bevel gear 43. When the first drive motor 42 starts, it drives the drive rod 421 to generate rotational torque. Due to the engagement structure between the guide groove and the protrusion, this rotational motion is directly transmitted to the first driving bevel gear 43, causing it to rotate while sliding axially.

[0040] Once the first driving bevel gear 43 begins to rotate, it establishes a stable meshing relationship with the first driven bevel gear 471, thereby transmitting power to the second lead screw 47. The rotation of the second lead screw 47 will cause the moving block 49 on it to slide linearly along the groove inside the moving plate 46. It should be noted that the moving block 49 adopts a trapezoidal structure design, which not only increases the contact area with the groove, but also effectively improves the uniformity of force and resistance to disengagement during the sliding process, thereby ensuring the smoothness and structural stability during the movement.

[0041] Through the coordinated operation of the second drive motor 44 and the first drive motor 42, multi-dimensional and precise adjustment of the position of the grinder 481 can be achieved. Whether it is the increase in height or the translation of the horizontal position, the ultimate goal is to perform high-precision and high-efficiency grinding on the surface of the metal unibody plate.

[0042] The device's operation and working principle are as follows: When polishing a one-piece metal plate, it is first fixed between two flip plates 551 by the locking bracket 55. After starting the third drive motor 51, the flipping rod 52 rotates accordingly, driving one side of the flip plate 551 to move via the drive block 521. Under the coordinated action of the second sliding block 58 moving linearly along the first limiting bracket 53 and the second limiting bracket 54, and the first sliding block 57 moving vertically along the first track 531 and the second track 541, the locking bracket 55 drives the one-piece metal plate to rotate smoothly, allowing for polishing on both sides. The notch structure in the middle of the first limiting bracket 53 and the first track 531 ensures that the threaded rod 552 at the top of the flipping rod 52 can apply a clamping force to the one-piece metal plate from the bottom, achieving reliable fixation.

[0043] During the polishing process, the second drive motor 44 drives the belt transmission assembly 441, which in turn drives the two first lead screws 45 to rotate synchronously. This causes the moving plate 46 to move along the first lead screws 45, thereby adjusting the lateral position of the polisher 481. Simultaneously, the cylinder 3, guided by the slide rod 2, pushes the polisher 481 to adjust its height to adapt to different polishing requirements. When the moving plate 46 moves, the first drive bevel gear 43 slides on the surface of the drive rod 421 but does not affect the transmission.

[0044] After the first drive motor 42 starts, the drive rod 421 drives the first active bevel gear 43 to rotate, which in turn rotates the second lead screw 47 by meshing with the first driven bevel gear 471, thereby pushing the moving block 49 to slide stably within the moving plate 46. The moving block 49 adopts a trapezoidal structure, which enhances its rigidity and anti-dislodgement reliability during movement. Through the coordinated control of the second drive motor 44 and the first drive motor 42, the position and direction of the grinder 481 can be flexibly adjusted, thereby enabling precise grinding of the metal unibody plate.

[0045] In addition, a camera 641 is installed for monitoring. Rotating the second rotating rod 67 drives the second driven gear 692 to rotate, which in turn drives the first transmission gear 632 to rotate, causing the second driving bevel gear 66 to mesh with the second driven bevel gear 642. This ultimately drives the rotating frame 64 to adjust the angle of the camera 641. When the first rotating rod 63 drives the first driving gear 631 to rotate, the central column 691 drives the rotating column 65 and the rotating frame 64 to rotate as a whole, thereby achieving synchronous adjustment of the camera 641's position and angle, effectively expanding the monitoring range. The viewing angle can be adjusted in real time during the grinding process, ensuring operational visibility and process control.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
