Description

Technical Field

[0001] This invention relates to the field of intelligent welding technology, and in particular to an intelligent laser welding system for filter discs. Background Technology

[0002] Disc filters are a type of high-efficiency and reliable precision filtration component. Their core design concept stems from overcoming the limitations of traditional filtration methods. Before the advent of disc filters, traditional filtration equipment such as sand filters generally suffered from pain points such as limited filtration accuracy, large equipment size, high backwash water consumption, and complex operation and maintenance. Disc filters not only achieve stable filtration over a wide range of accuracy, but their modular design also provides a structural foundation for the subsequent realization of efficient, low-consumption, fully automatic backwashing functions, marking a new stage in physical filtration technology.

[0003] Current filter discs are typically composed of multiple layers. Therefore, during the production process, the outer circumference of the disc needs to be welded to form a unified structure. Chinese Patent Publication No. CN214721843U discloses a filter disc outer circumference welding device. Its technical feature is that the disc is clamped by jigs on both sides, and the outer circumference welding is completed by rotating the disc. This shows that existing disc welding technologies mostly employ side-clamping and rotational welding. However, to ensure a tight fit between each layer of the disc, significant clamping pressure is usually applied to both sides. This greater clamping pressure results in a tight fit in the middle of the disc area, but the edges are prone to warping. This leads to a wider and uneven weld seam during the outer circumference welding. Furthermore, the unevenly warped disc edges, when welded together, generate internal stress. During the use of the filter disc, this stress at the edge interacts with the forces in the environment, making it easy to find a point of failure in the uneven weld seam on the outer circumference, leading to localized detachment of the filter disc edges and severely impacting its lifespan. Summary of the Invention

[0004] To address this issue, the present invention provides an intelligent laser welding system for filter discs, which solves the problem of wide and uneven weld seams in the welding of the outer circle of filter discs in the prior art.

[0005] To achieve the above objectives, the present invention provides an intelligent laser welding system for filter discs, comprising:

[0006] The clamping and rotating unit includes a rotating clamping plate and a movable clamping plate arranged concentrically and horizontally, which are used to clamp the filter disc to be welded by the rotating clamping plate and the movable clamping plate, and drive the clamped filter disc to rotate axially.

[0007] The roller clamping unit is used to clamp the edge of the filter disc held by the roller gripper mechanism and maintain the clamping on the edge of the filter disc when the filter disc rotates. The clamping pressure of the roller gripper mechanism is adjustable.

[0008] The scanning welding unit is used to scan the width of the outer circumference gap of the clamped filter disc and complete the circumferential welding of the outer circumference of the filter disc as the filter disc rotates.

[0009] The central control unit is connected to the clamping and rotating unit, the roller clamping unit, and the scanning and welding unit. The central control unit can generate an angle width curve based on the outer circle gap width data of the filter disc scanned by the scanning and welding unit. When all gap width data in the angle width curve are within the standard gap width range, the central control unit determines the absolute value of the maximum slope of the angle width curve based on the standard slope to determine the welding of the outer circle of the filter disc or the clamping pressure of the roller clamping mechanism.

[0010] Furthermore, the central control unit can also issue a prompt to re-clamp or replace the filter disc under the first preset conditions;

[0011] The first preset condition is that the gap width data in the angle width curve is not within the standard gap width range.

[0012] Furthermore, when the absolute value of the maximum slope of the angle width curve is greater than the standard slope, the central control unit can increase the clamping pressure of the adjusting roller gripper mechanism and control the scanning welding unit to rescan the outer circle gap width of the filter disc to generate a new angle width curve.

[0013] Furthermore, the central control unit is also equipped with a warning clamping pressure. When the clamping pressure of the adjusted roller clamping mechanism exceeds the warning clamping pressure, the central control unit can issue a prompt to re-clamp or replace the filter disc.

[0014] Furthermore, the outer side of the rotating chuck is connected to one end of the rotating shaft, and the other end of the rotating shaft is connected to the output shaft of the control motor. The control motor can drive the rotating chuck to rotate axially through the rotating shaft.

[0015] Furthermore, a rotating bearing is provided on the outer side of the movable clamping plate. The rotating bearing is connected to the movable shaft. One end of the movable shaft is a smooth shaft, and the other end is a lead screw shaft. One end of the smooth shaft of the movable shaft passes through the through hole of the movable retainer and is connected to the rotating bearing. One end of the lead screw shaft of the movable shaft is inserted into the lead screw motor. The lead screw motor can drive the rotation of the lead screw shaft part of the movable shaft to move the entire movable shaft axially, thereby driving the movable clamping plate to approach the rotating clamping plate to clamp the filter disc, or driving the movable clamping plate to move away from the rotating clamping plate to release the clamped filter disc.

[0016] Furthermore, the roller clamping unit includes a roller gripper mechanism and a first lifting mechanism. The top of the first lifting mechanism is provided with a fixed connecting body, and the roller gripper mechanism is horizontally arranged on the fixed connecting body. The first lifting mechanism can adjust the position and height of the roller gripper mechanism by lifting and lowering.

[0017] Furthermore, the roller gripper mechanism includes a first gripper arm and a second gripper arm connected by hinges. Both the first gripper arm and the second gripper arm are provided with pressure rollers at their ends. The pressure rollers can rotate as the filter disc rotates when the filter disc is pressed.

[0018] Furthermore, a compression spring is provided on the inner side of the first clamping arm. One end of the compression spring is fixedly connected to the first clamping arm, and the other end of the compression spring is fixedly connected to an adjusting screw. The adjusting screw passes through the second clamping arm and is connected to a screw motor fixedly installed on the outer side of the second clamping arm. The screw motor is used to adjust the extension length of the adjusting screw into the inner side of the second clamping arm by rotation, so as to control the elastic force of the compression spring.

[0019] Furthermore, the scanning welding unit includes a multi-functional welding pad, and several connecting pins are arranged on the outer circumference of the multi-functional welding pad. The multi-functional welding pad is connected to the laser welding gun and the width measuring instrument respectively through the connecting pins. The multi-functional welding pad can switch between the laser welding gun and the width measuring instrument by rotating.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting up a clamping and rotating unit, the filter disc is driven to rotate axially while being squeezed and clamped, making the welding of the outer circle of the filter disc more convenient. The set roller pressing unit can further press the edge of the filter disc, effectively reducing the width of the outer circle gap of the filter disc, and thus reducing the width of the weld after welding. At the same time, by scanning the width of the outer circle gap of the filter disc by the scanning welding unit, the central control unit makes real-time judgment feedback adjustment, ensuring the uniformity of the width of the outer circle gap of the filter disc. This makes the size of the outer circle weld of the filter disc controllable and the width uniform, ensuring the welding quality of the filter disc and effectively improving the service life of the filter disc.

[0027] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0028] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0029] It should be noted that in the description of this invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc., which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0030] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] Please see Figure 1As shown, this embodiment provides an intelligent laser welding system for filter discs, including a support platform 1, a clamping and rotating unit, a roller pressing unit, a scanning and welding unit, and a central control unit. The central control unit is an external computer device, which is not shown in the figure.

[0032] The clamping and rotating unit is used to clamp the filter discs to be welded and to drive the clamped filter discs to rotate axially.

[0033] Specifically, the clamping and rotating unit includes a rotating clamping plate 2 and a movable clamping plate 3. Both the rotating clamping plate 2 and the movable clamping plate 3 are circular disc structures and are arranged concentrically and horizontally.

[0034] The outer side of the rotating chuck 2 is connected to one end of the rotating shaft 201, and the other end of the rotating shaft 201 is connected to the output shaft of the control motor 202. By controlling the rotation of the control motor 202, the rotating chuck 2 is driven to rotate axially. At the same time, the rotating shaft 201 also passes through the rotating retainer 203 with a through hole. The bottom of the rotating retainer 203 is connected to the support platform 1. The rotating retainer 203 can ensure the radial stability of the rotating chuck 2 when it rotates, and prevent the rotating chuck 2 from jumping during rotation. In order to ensure that the rotating shaft 201 rotates smoothly in the through hole of the rotating retainer 203, the friction between the rotating shaft 201 and the inner wall of the through hole of the rotating retainer 203 can be reduced by setting a bearing in the through hole of the rotating retainer 203. The bottom of the control motor 202 is provided with a first bracket 204, which is connected to the support platform 1. The first bracket 204 can effectively reduce the vibration of the control motor 202 and ensure the rotational stability of the rotating chuck 2.

[0035] A rotating bearing 301 is provided on the outer side of the movable clamping plate 3. The rotating bearing 301 is connected to the movable shaft 302. One end of the movable shaft 302 is a smooth shaft, and the other end is a lead screw shaft. One end of the smooth shaft of the movable shaft 302 passes through the through hole of the movable retainer 303 and is connected to the rotating bearing 301. One end of the lead screw shaft of the movable shaft 302 is inserted into the lead screw motor 304. The lead screw motor 304 drives the rotation of the lead screw shaft part of the movable shaft 302 to realize the axial movement of the entire movable shaft 302, thereby driving the movable clamping plate 3 to move closer to the rotating clamping plate 2 to clamp the filter disc, or driving the movable clamping plate 3 away from the rotating clamping plate 2 to release the clamped filter disc. At the same time, the movable retainer 303 is connected to the support platform 1. A second bracket 305 is provided at the bottom of the lead screw motor 304. The second bracket 305 is also connected to the support platform 1 to ensure the stability of the overall structure.

[0036] In this embodiment, the rotating clamp 2 cannot move axially; it can only rotate under the drive of the control motor 202. The outer side of the movable clamp 3 is provided with a rotating bearing 301, which allows the movable clamp 3 to rotate freely relative to the movable shaft 302. Therefore, when the rotating clamp 2 and the movable clamp 3 clamp the filter disc, the axial movement of the movable shaft 302 exerts pressure on the rotating clamp 2, the movable clamp 3, and the filter disc. At this time, the rotating clamp 2, the movable clamp 3, and the filter disc can be regarded as a whole, and the whole rotation is achieved by the drive of the control motor 202.

[0037] Please continue reading. Figure 2 As shown, the roller clamping unit is used to clamp the edge of the held filter disc and maintain the clamping on the edge of the filter disc as the filter disc rotates;

[0038] Specifically, the roller clamping unit includes a roller gripper mechanism 5 and a first lifting mechanism 4. The top of the first lifting mechanism 4 is provided with a fixed connecting body 401, and the roller gripper mechanism 5 is horizontally arranged on the fixed connecting body 401. A horizontal slide rail 101 is provided on the bearing platform 1, and the bottom of the first lifting mechanism 4 is connected to the horizontal slide rail 101 on the bearing platform 1, so that the roller clamping unit can move horizontally relative to the bearing platform 1 to be suitable for welding filter discs of different thicknesses. At the same time, the lifting of the first lifting mechanism 4 can drive the roller gripper mechanism 5 to adjust its height to be suitable for welding filter discs of different diameters.

[0039] Please continue reading. Figure 3 As shown, the roller gripper mechanism 5 includes a first gripper arm 501 and a second gripper arm 502 connected by hinges. Each end of the first gripper arm 501 and the second gripper arm 502 is provided with a pressure roller 503. The pressure roller 503 has a cylindrical structure. When the pressure rollers 503 on both sides press the filter disc, the cylindrical pressure roller 503 can rotate with the rotation of the filter disc to maintain stable pressing pressure. The hinged ends of the first gripper arm 501 and the second gripper arm 502 are also connected to a first telescopic rod 504. The first telescopic rod 504 adjusts the working position of the pressure roller 503 by telescopic adjustment.

[0040] A compression spring 505 is provided on the inner side of the first clamping arm 501. One end of the compression spring 505 is fixedly connected to the first clamping arm 501, and the other end of the compression spring 505 is fixedly connected to an adjusting screw 506. The adjusting screw 506 passes through the second clamping arm 502 and is connected to a screw motor 507 fixedly provided on the outer side of the second clamping arm 502. The screw motor 507 is used to adjust the extension length of the adjusting screw 506 into the inner side of the second clamping arm 502 by rotation, thereby controlling the compression spring 505. The spring force is used to control the pressure between the two pressure rollers 503. When the extension length of the adjusting screw 506 into the inner side of the second clamping arm 502 is relatively long, the spring force of the clamping spring 505 is small. When the extension length of the adjusting screw 506 into the inner side of the second clamping arm 502 is relatively short, the clamping spring 505 is further stretched, so the spring force of the clamping spring 505 is large. The clamping spring 505 must always maintain a contraction trend so that the two pressure rollers 503 move closer to each other to achieve the clamping effect.

[0041] The scanning welding unit is used to scan the width of the outer circumference gap of the clamped filter disc and complete the circumferential welding of the outer circumference of the filter disc as the filter disc rotates.

[0042] Specifically, the scanning welding unit includes a multi-functional solder pad 6, a second lifting mechanism 7, and a support cross arm 8. The second lifting mechanism 7 is mounted on a fixed connecting body 401 at the top of the first lifting mechanism 4. The support cross arm 8 is horizontally mounted at the top of the second lifting mechanism 7. The multi-functional solder pad 6 is connected to the bottom surface of the support cross arm 8. The second lifting mechanism 7 can adjust the height of the multi-functional solder pad 6 by lifting, thereby controlling the relative distance between the multi-functional solder pad 6 and the roller gripper mechanism 5.

[0043] Please continue reading. Figure 4 As shown, the multi-functional solder pad 6 has a circular disk structure. The multi-functional solder pad 6 is connected to the support cross arm 8 through the support frame 601, so that the multi-functional solder pad 6 can rotate relative to the support cross arm 8. Multiple connecting pins 602 are provided on the outer circumference of the multi-functional solder pad 6. The multi-functional solder pad 6 is connected to the laser welding gun 603 and the width measuring instrument 604 through the connecting pins 602 respectively. The width measuring instrument 604 is used to scan the outer circumference gap width of the clamped filter disc. The laser welding gun 603 welds the outer circumference of the filter disc. The rotation of the multi-functional solder pad 6 can be controlled by a motor, thereby realizing the function switching of the multi-functional solder pad 6.

[0044] In this embodiment, the width measuring instrument 604 can use laser width measurement or CCD image width measurement. The laser welding gun 603 needs to be selected according to the actual welding output material and process. In this embodiment, the multi-functional welding pad 6 is provided with four connecting pins 602. The laser welding gun 603 and the width measuring instrument 604 are each connected through one connecting pin 602. In actual production, welding guns of different specifications or other functional components can also be set on the idle connecting pins 602, which can improve the applicability and flexibility of the welding system.

[0045] Please continue reading. Figure 5 As shown, the support frame 601 of the multi-functional solder pad 6 is provided with a slider 605 at its end. The multi-functional solder pad 6 is connected to the support cross arm 8 by embedding the slider 605 at the end of the support frame 601 into the groove 801 inside the support cross arm 8. At the same time, a second telescopic rod 802 is also connected to one side of the slider 605. The second telescopic rod 802 can be extended and retracted by a motor. By controlling the extension and retraction of the second telescopic rod 802, the multi-functional solder pad 6 can be moved relative to the support cross arm 8, thereby controlling the soldering position.

[0046] The central control unit is connected to the clamping and rotating unit, the roller pressing unit, and the scanning and welding unit respectively, and is used to control the working status of each component;

[0047] Specifically, the central control unit has a standard gap width range. During the outer circumference welding of the filter disc, the moving clamping plate 3 is brought close to the rotating clamping plate 2 to hold the filter disc. The operator clamps the roller gripper mechanism 5 with initial pressure at the edge of the filter disc. The central control unit drives the multi-functional welding plate 6 to rotate, so that the width measuring instrument 604 faces the gap on the outer circumference of the filter disc. Then, the control motor 202 is started, driving the filter disc to rotate one full turn, that is, rotate 360°. The central control unit generates a data curve of rotation angle versus gap width based on the gap width data of the outer circumference of the filter disc scanned by the width measuring instrument 604, which is the angle width curve. The central control unit then judges all gap width data in the angle width curve according to the standard gap width range.

[0048] If the gap width data in the angle width curve is not within the standard gap width range, the central control unit determines that the filter disc is defective or misaligned, and the central control unit will issue a prompt to re-clamp or replace the filter disc.

[0049] If all gap width data in the angle width curve are within the standard gap width range, the central control unit will make a uniformity judgment based on the angle width curve.

[0050] The central control unit is equipped with a standard slope. When determining the uniformity of the angle width curve, the central control unit will calculate the absolute value of the maximum slope on the angle width curve.

[0051] If the absolute value of the maximum slope of the angle width curve is greater than the standard slope, the central control unit will determine that the uniformity of the angle width curve is unqualified. The central control unit will control the screw motor 507 to adjust the initial clamping pressure of the roller gripper mechanism 5 to increase the clamping pressure of the roller gripper mechanism 5, and start the control motor 202 to drive the filter disc to rotate one revolution, so that the width measuring instrument 604 can rescan and generate a new angle width curve.

[0052] If the absolute value of the maximum slope of the angle width curve is less than or equal to the standard slope, the central control unit determines that the uniformity of the angle width curve is qualified. The central control unit will control the multi-functional welding disk 6 to rotate, so that the laser welding gun 603 is directed toward the gap of the outer circle of the filter disc, and start the control motor 202 to make the filter disc rotate. The outer circle of the filter disc is welded by the laser welding gun 603.

[0053] In this embodiment, the threshold values ​​set in the central control unit need to be set according to the actual process. Taking a filter disc with an outer diameter of 381mm as an example, the standard gap width is set to 0-2.2mm, and the corresponding standard slope is set to 1.35. Of course, in actual settings, the horizontal and vertical coordinate units of the generated angle width curve also need to be considered, which will not be elaborated here.

[0054] In this embodiment, the central control unit is also equipped with a warning clamping pressure. When the clamping pressure of the roller clamping mechanism 5 after the central control unit increases and adjusts is higher than the warning clamping pressure, the central control unit will issue a prompt to re-clamp or replace the filter disc; to avoid the edge of the filter disc being excessively squeezed, which would create new internal stress after welding.

[0055] The intelligent laser welding system for filter discs in this embodiment adds a roller clamping unit to the conventional filter disc outer circle welding equipment, effectively reducing the width of the gap on the outer circle of the filter disc, thus reducing the weld seam size. Simultaneously, the roller gripper mechanism 5 effectively reduces edge warping of the filter disc. A central control unit and a width measuring instrument 604 are also included to generate an angle-width curve. High-precision welding is achieved through precise software control. Furthermore, data judgment is performed using the generated angle-width curve, improving accuracy and facilitating the generation of corresponding welding strategies. For example, if the operating accuracy of the control motor 202 allows, the speed of the control motor 202 can be controlled according to the angle-width curve. In areas with larger gap widths, the speed of the control motor 202 is reduced, increasing the dwell time of the laser welding gun 603, thereby allowing more welding filler to be obtained in that area and improving welding stability. The intelligent laser welding system for filter discs in this embodiment has a high degree of adjustment freedom and is also suitable for precision welding processes on the outer circles of other disc structures. It can be customized and set according to actual application conditions.

[0056] In summary, the intelligent laser welding system for filter discs in this embodiment effectively solves the problems of easy edge lifting during filter disc clamping and wide and uneven weld seams during welding, improves the welding quality of the outer circle of the filter disc, and achieves intelligent precision welding.

Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
