Description

Technical Field

[0001] The invention relates to the technical field of robot laser welding auxiliary equipment, in particular to a robot laser welding guiding device. Background Art

[0002] The working principle of the robot laser welding guidance device is mainly based on optical imaging and computer control technology. During the welding process, the laser weld tracker captures the image information of the weld in real time and converts it into digital signals. The control system processes and analyzes these digital signals and calculates the optimal movement trajectory of the welding head through an algorithm. The control system then sends instructions to the mechanical structure to drive the welding head to move along a predetermined path. During the movement, the laser beam is always aimed at the weld for heating and melting, thereby forming a high-quality weld.

[0003] When laser welding is guided on the weld, a high-precision visual sensor is needed to take a picture of the weld. When taking pictures, the light in the workshop is dim, resulting in shadows on the weld surface. As a result, the high-precision visual sensor will have uneven image brightness in the weld area due to the shadows when working, making the features of the weld blurred or difficult to identify. This degradation in image quality will directly affect the visual sensor's accurate detection and tracking of the weld. In the process of weld identification and tracking, the visual sensor needs to extract key features such as the weld boundary and shape from the image. However, the presence of shadows will interfere with the extraction of these features, making the extraction process complicated and difficult. Improvements are needed to address this problem. Summary of the invention

[0004] The object of the present invention is to provide a robot laser welding guiding device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a robot laser welding guide device, comprising a supporting foot, and also comprising a laser welding component, a lighting component, an angle adjustment component and an auxiliary component. The top of the supporting foot is fixedly connected to a workbench, and the top of the workbench is fixedly connected to a movable guide frame.

[0006] Wherein, the laser welding assembly comprises:

[0007] The second movable guide frame is slidably connected to the outer side of the first movable guide frame.

[0008] The travel motor 1 is used for driving the movable guide frame 2 to slide forward and backward on the outer side of the movable guide frame 1.

[0010] The second travel motor is used to drive the moving frame to slide horizontally left and right outside the second moving guide frame.

[0011] The laser welder is arranged on the front of the mobile frame.

[0012] According to the above technical solution, the lighting assembly includes an image capturer, an illumination lamp, a fixed support plate, an electric telescopic rod, a lifting guide rod, a lifting movable plate and an angle adjustment plate. The image capturer is fixedly connected to the front of the laser welder, the illumination lamp is arranged on the left and right sides of the bottom of the image capturer, the fixed support plate is fixedly connected to the top of the outer side of the image capturer, the electric telescopic rod is fixedly connected to the middle of the top of the fixed support plate, the fixed support plate has a telescopic end, the lifting movable plate is fixedly connected to the telescopic end of the fixed support plate, the lifting guide rod is fixedly connected to the left and right sides of the bottom of the fixed support plate, and the angle adjustment plate is fixedly connected to the bottom of the left and right sides of the image capturer.

[0013] According to the above technical solution, the angle adjustment assembly includes an electric telescopic rod 2, a rotating block, an adjusting rotating frame and an adjusting reflector. The electric telescopic rod 2 is fixedly connected to the side of the lifting and moving plate away from the image capture device. The electric telescopic rod 2 has a telescopic end. The rotating block is fixedly connected to the telescopic end of the electric telescopic rod 2. The adjusting rotating frame is rotatably connected to the middle part of the rotating block. The adjusting reflector is fixedly connected to the bottom of the adjusting rotating frame.

[0014] According to the above technical solution, the auxiliary component includes an adjustment movable groove, a fixed plate, a spring and a guide cleaning frame, the adjustment movable groove is opened inside the angle adjustment plate, the fixed plate is fixedly connected to the side of the fixed plate close to the image capture device, the spring is fixedly connected to the side of the fixed plate away from the image capture device, and the guide cleaning frame is fixedly connected to the other end of the spring.

[0015] According to the above technical solution, the bottom of the lifting guide rod is fixedly connected to the top of the angle adjustment plate, sliding holes are provided on the front and rear sides of the lifting and movable plate, and the lifting and movable plate is slidably connected to the outer wall of the angle adjustment plate through the sliding holes. A circular hole is provided in the middle of the fixed support plate, and the telescopic end of the electric telescopic rod passes through the circular hole and extends to the lower side of the fixed support plate and is fixedly connected to the top of the lifting and movable plate, so that the electric telescopic rod can control the lifting and movable plate to perform lifting work when working.

[0016] According to the above technical solution, the guide cleaning frame is set with an inclined surface, and the material of the inclined surface of the guide cleaning frame is suede leather. The guide cleaning frame is set in the adjustment movable groove. By setting one side of the guide cleaning frame as an inclined surface, the bottom of the adjustment reflector can be matched with the inclined surface of the guide cleaning frame when the adjustment reflector is in a vertical state, so as to prevent the adjustment reflector from escaping upward from the angle adjustment plate. At the same time, by setting the material of the inclined surface of the guide cleaning frame to suede leather, the surface of the guide cleaning frame can be cleaned when the inclined surface of the guide cleaning frame contacts the adjustment reflector.

[0017] According to the above technical solution, the number of the fixed support plate, the electric telescopic rod 1, the lifting guide rod, the lifting movable plate, the angle adjustment plate, the electric telescopic rod 2, the rotating block, the adjusting rotating frame, the adjusting reflector, the adjusting movable groove, the fixed plate, the spring and the guide cleaning frame are all two. The two fixed support plates, the electric telescopic rod 1, the lifting guide rod, the lifting movable plate, the angle adjustment plate, the electric telescopic rod 2, the rotating block, the adjusting rotating frame, the adjusting reflector, the adjusting movable groove, the fixed plate, the spring and the guide cleaning frame are symmetrically distributed on the left and right sides of the image capture device, and the rotating angle of the adjusting reflectors on both sides can be controlled at the same time to adjust the reflection position and intensity.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: in the present invention, when laser welding is required, the raw material plate is placed on the top of the workbench, and then the walking motor 1 is controlled to work, so that the walking motor 1 drives the moving guide frame 2 to move forward and backward on the moving guide frame 1, and at the same time, the walking motor 2 is driven to drive the moving frame to move left and right on the moving guide frame 2, and the image capturer is controlled to work so that the image capturer performs welding work on the surface of the raw material plate, and the position during welding can be adjusted by setting the walking motor 2 and the walking motor 1;

[0019] When laser welding guidance is required, the image capturer moves synchronously with the laser welder when the laser welder is controlled to work, and the lighting lamp is controlled to illuminate the weld surface when the lighting lamp is working, and the image capturer collects images of the weld when the image capturer is working;

[0020] When the lighting lamp is collecting images of the weld, the convex part of the weld produces a shadow that affects the concave part. At this time, the electric telescopic rod 1 is controlled to work. When the electric telescopic rod 1 is working, the electric telescopic rod 1 pushes the lifting and moving plate to move downward. When the lifting and moving plate moves downward, the electric telescopic rod 2 is controlled to work, so that the electric telescopic rod 2 pushes and pulls the rotating block to move, so that the rotating block squeezes the adjusting rotating frame, so that when the adjusting reflector slides in the adjusting moving groove on the angle adjusting plate, the rotating angle of the adjusting reflector is controlled. At the same time, the contact between the adjusting reflector and the guide cleaning frame can be adjusted. The guide work is performed to adjust the angle of the reflector when it moves downward, so that the reflector is tilted and moved downward, and at the same time, the light diffusely reflected to the outside when the lighting lamp is working is reflected. When the lifting and moving plate moves downward to the lower part of the outer side of the lifting and guiding rod, the inclination angle of the adjusting reflector is maximized. When the lifting and moving plate moves upward to the upper part of the outer side of the lifting and guiding rod, the inclination angle of the adjusting reflector becomes smaller, and the guide cleaning frame is squeezed to compress the spring, and at the same time, the reflector is adjusted to a vertical state, so that the device can adjust the reflection angle as needed when working, making the device more flexible when used;

[0021] When the electric telescopic rod is controlled to drive the lifting movable plate to lift outside the lifting guide rod, the adjusting reflector is brought into contact with the guiding cleaning frame on the side close to the guiding cleaning frame, so that the guiding cleaning frame scrapes the surface of the adjusting reflector, and dust adhered to the surface of the adjusting reflector and particles cooled by sparks adhered during welding can be scraped off to avoid affecting the reflective efficiency of the adjusting reflector, so that the device can keep the surface of the adjusting reflector clean during operation and perform self-cleaning operation on it;

[0022] When welding, the electric telescopic rod 1 is controlled to drive the lifting movable plate to rise outside the lifting guide rod, and the electric telescopic rod 2 is extended to drive the rotating block and the adjusting reflector to a vertical state. Then, under the operation of the electric telescopic rod 1, the adjusting reflector is stored to the left and right sides of the image capture device, so that the device has a storage and folding function, avoiding the influence of the line of sight blocking during welding and causing errors during welding;

[0023] By setting the adjustable reflector, the adjustable reflector can reflect light to the subject or the area that needs lighting, significantly increasing the brightness of the area, making the subject or object brighter and clearer. In an environment with insufficient light or heavy shadows, the adjustable reflector can reflect light to the dark part of the subject, reducing the shadow area, making the overall picture more uniform and natural, and at the same time making the subject more vivid and prominent, ensuring the efficiency of image acquisition.

[0044] The bottom of the lifting guide rod 505 is fixedly connected to the top of the angle adjustment plate 507, and sliding holes are provided on the front and rear sides of the lifting and moving plate 506.

[0045] The guide cleaning frame 704 is set as an inclined surface, and the inclined surface material of the guide cleaning frame 704 is suede leather. The guide cleaning frame 704 is set in the adjustment movable groove 701. By setting one side of the guide cleaning frame 704 as an inclined surface, the bottom of the adjustment reflector 604 can be matched with the inclined surface of the guide cleaning frame 704 when it is in a vertical state, so as to prevent the adjustment reflector 604 from escaping upward from the angle adjustment plate 507. At the same time, by setting the inclined surface material of the guide cleaning frame 704 to suede leather, the surface of the guide cleaning frame 704 can be cleaned when the inclined surface of the guide cleaning frame 704 contacts the adjustment reflector 604.

[0046] There are two fixed support plates 503, electric telescopic rod 1 504, lifting guide rod 505, lifting movable plate 506, angle adjustment plate 507, electric telescopic rod 2 601, rotating block 602, adjusting rotating frame 603, adjusting reflector 604, adjusting movable groove 701, fixed plate 702, spring 703 and guide cleaning frame 704. The two fixed support plates 503, electric telescopic rod 1 504, lifting guide rod 505, lifting movable plate 506, angle adjustment plate 507, electric telescopic rod 2 601, rotating block 602, adjusting rotating frame 603, adjusting reflector 604, adjusting movable groove 701, fixed plate 702, spring 703 and guide cleaning frame 704 are symmetrically distributed on the left and right sides of the image capture device 501, and can simultaneously control the rotation angle of the adjusting reflector 604 on both sides to adjust the reflection position and intensity.

[0047] When laser welding is required, the raw material plate is placed on the top of the workbench 2, and then the walking motor 402 is controlled to work, so that the walking motor 402 drives the moving guide frame 401 to move forward and backward on the moving guide frame 3. At the same time, by driving the walking motor 404, the walking motor 404 drives the moving frame 403 to move left and right on the moving guide frame 401, and the image capturer 501 is controlled to work so that the image capturer 501 performs welding on the surface of the raw material plate. By setting the walking motor 404 and the walking motor 402, the position during welding can be adjusted.

[0048] When laser welding guidance is required, when the laser welder 405 is controlled to work, the image capturer 501 moves synchronously with the movement of the laser welder 405, and controls the lighting lamp 502 to work, so that the lighting lamp 502 illuminates the weld surface when working, and the image capturer 501 collects images of the weld when working.

[0049] When the lighting lamp 502 is collecting images of the weld, a shadow is generated at the convex part of the weld to affect the concave part. At this time, the electric telescopic rod 1 504 is controlled to work. When the electric telescopic rod 1 504 is working, the electric telescopic rod 1 504 pushes the lifting and moving plate 506 to move downward. When the lifting and moving plate 506 moves downward, the electric telescopic rod 2 601 is controlled to work, so that the electric telescopic rod 2 601 pushes and pulls the rotating block 602 to move, so that the rotating block 602 squeezes the adjusting rotating frame 603, and when the adjusting reflector 604 slides in the adjusting moving groove 701 on the angle adjusting plate 507, the rotating angle of the adjusting reflector 604 is controlled, and at the same time, the reflector 604 and the guide cleaning frame 704 are adjusted. When the lifting and moving plate 506 moves downward to the lower part of the outer side of the lifting guide rod 505, the inclination angle of the adjusting reflector 604 is maximized. When the lifting and moving plate 506 moves upward to the upper part of the outer side of the lifting and guiding rod 505, the inclination angle of the adjusting reflector 604 is reduced, and the guide cleaning frame 704 is squeezed to compress the spring 703. At the same time, the reflector 604 is adjusted to a vertical state, so that the device can adjust the reflection angle as needed during operation, making the device more flexible when used.

[0050] When the electric telescopic rod 504 is controlled to drive the lifting movable plate 506 to perform lifting work outside the lifting guide rod 505, the adjusting reflector 604 is made to contact the guiding cleaning frame 704 on the side close to the guiding cleaning frame 704, so that the guiding cleaning frame 704 scrapes the surface of the adjusting reflector 604, and the dust adhered to the surface of the adjusting reflector 604 and the particles cooled by the sparks adhered during welding can be scraped off to avoid affecting the reflective efficiency of the adjusting reflector 604, so that the device can keep the surface of the adjusting reflector 604 clean during operation and perform self-cleaning work on it.

[0051] When welding, the electric telescopic rod 1 504 is controlled to drive the lifting movable plate 506 to rise on the outside of the lifting guide rod 505, so that the electric telescopic rod 2 601 is extended to drive the rotating block 602 and the adjustment reflector 604 to a vertical state, and then the electric telescopic rod 1 504 is operated to make the adjustment reflector 604 stored on the left and right sides of the image capture device 501, so that the device has a storage and folding function, which can avoid blocking the line of sight during welding and causing errors during welding.

[0052] By setting the adjustable reflector 604, the adjustable reflector 604 can reflect light to the subject or the area that needs lighting, significantly increasing the brightness of the area, making the subject or object brighter and clearer. In an environment with insufficient light or heavy shadows, the adjustable reflector 604 can reflect light to the dark part of the subject, reducing the shadow area, making the overall picture more uniform and natural, and at the same time making the subject more vivid and prominent, ensuring the efficiency of image acquisition.
