Description

Technical Field

[0001] This invention relates to the field of laser welding technology, specifically to a laser welding device that is easy to operate. Background Technology

[0002] Laser welding equipment is a high-tech processing tool that uses a high-energy-density laser beam as a heat source to achieve precise connection by melting materials. It is widely used in automobile manufacturing, electronic components, medical devices and other fields, and has advantages such as high precision, low heat-affected zone and high weld quality.

[0003] For example, patent CN218904082U discloses an automatic flipping mechanical welding device. This patent uses a simple locking and disassembly mechanism to effectively lock the flipping mechanism, improving its stability and preventing rotation. This facilitates welding point positioning and welding operations, and allows for quick replacement of clamping components, enabling stable clamping of different types of mechanical parts and greatly simplifying mechanical welding. However, in practical use, this type of welding device requires multiple drive sources to achieve the flipping and locking functions, increasing equipment costs and operational steps. Furthermore, during flipping, it's not convenient to apply force to both ends of the plate-shaped workpiece simultaneously; only the plate itself can drive the other end to rotate. Therefore, before the workpiece is fully welded, the weld joint is still subject to external force, affecting the workpiece's stability. Similarly, locking can only lock one end, resulting in relatively poor overall stability. After welding, the horizontal position of the welding torch needs to be reset before welding the other side of the workpiece, requiring a certain reset time, which affects overall welding efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a laser welding device that is easy to operate, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser welding device that is easy to operate, comprising a frame and a tilting assembly. A top plate is provided on the top of the frame, and a welding assembly is provided in the middle of the top plate. The tilting assembly is located at the lower part of the frame and includes an electric cylinder. The electric cylinder is installed at the lower part of the frame, and a T-shaped plate is fixedly connected to one end of the electric cylinder. The T-shaped plate is slidably connected to the frame. Drive plates are installed at both ends of the T-shaped plate, and a circular hole is provided at the upper end of the drive plate. A drive column is provided on the wall of the circular hole at the upper end of the drive plate.

A guide groove is provided on the outer side of the rotating shaft. A mounting base is fixed at the end of the rotating shaft away from the drive plate, and a clamping assembly is connected to one end of the mounting base.

[0006] Furthermore, the guide groove is composed of straight grooves on both sides and an inclined groove in the middle, and the drive column is slidably connected to the rotating shaft through the guide groove.

[0007] Furthermore, the welding assembly includes a motor, which is installed on one side of the middle of the top plate. The output shaft of the motor is connected to a lead screw. A movable seat is sleeved on the outer side of one end of the lead screw, and a light rod is slidably connected inside one end of the movable seat. The light rod is fixedly connected to the top plate. An electric telescopic rod is installed at the bottom of the movable seat, and a laser welding gun is installed at the bottom of the electric telescopic rod.

[0008] Furthermore, the clamping assembly includes an electric push rod, which is mounted on the lower end of one side of the mounting base. The telescopic end of the electric push rod is fixed with a guide plate, and the guide plate is slidably connected to the mounting base. The upper end of the guide plate is provided with an elongated hole, and a sliding column is slidably connected inside the wall of the elongated hole at the upper end of the guide plate.

[0009] Furthermore, a slider is fixed to one side of the sliding column, and the slider has an I-shaped cross-section. A limiting groove is provided on the upper part of the mounting base, and the limiting groove is arc-shaped. The slider is slidably connected to the mounting base through the limiting groove.

[0010] Furthermore, a clamp is provided on one side of the slider, and a screw is internally threaded to the upper end of the clamp. One end of the screw is rotatably connected to a pressure block, and a protrusion is slidably connected to the lower end of the pressure block.

[0011] Furthermore, the protrusion is triangular in shape, and a clamping plate is fixed to the bottom of the protrusion. The clamping plate is rotatably connected to the clamping seat, and a rubber pad is provided at one bottom end of the clamping plate.

[0012] Furthermore, a support is installed at the lower center of the frame, and the support is T-shaped, while clearance components are provided on both sides of the upper part of the frame.

[0013] Furthermore, the avoidance component includes a cam, and the cam is fixed to the outer side of one end of the rotating shaft near the mounting base. A roller seat is provided on the top of the cam, and a push rod is mounted on the top of the roller seat. The push rod is slidably connected to the protrusions with round holes on both sides of the upper part of the frame, and the top of the push rod is fixedly connected to the bottom of the top plate.

[0014] Furthermore, guide rods are symmetrically arranged on the top of the frame, and the guide rods are slidably connected to the top plate. A compression spring is sleeved on the outer side of the upper end of the guide rod, and the compression spring is tightly fitted to the top plate. A shock-absorbing pad is arranged on the outer side of the lower end of the guide rod.

[0015] This invention provides a laser welding device that is easy to operate and has the following advantages:

[0016] 1. This invention adjusts the height of the laser welding gun using an electric telescopic rod. Combined with the motor-driven lead screw and optical rod, it enables precise movement of the welding gun along the workpiece seam. After welding one side of the workpiece, the electric cylinder drives the T-shaped plate to drive the drive plate. By switching between the inclined and straight grooves on the guide slot, the rotation and locking of the rotating shaft can be precisely controlled, ensuring stability during the workpiece flipping welding process. In addition, the dual drive plate design allows the rotating shafts on both sides to apply force synchronously, avoiding interference to the workpiece due to differences in driving force on both sides. At the same time, the joint of the workpiece and the axis of the rotating shaft are located on the same plane, thus reducing the height change at the welding point after flipping, saving subsequent adjustment time. Furthermore, the workpiece automatically moves to the welding wire side of the laser welding gun after flipping, allowing continuous welding of the back side of the workpiece without resetting the laser welding gun, simplifying the operation steps and significantly improving welding efficiency.

[0017] 2. This invention utilizes an electric push rod to adjust the height of the guide plate, and the linkage between the sliding column and the slider can change the tilt angle of the mounting base. Combined with the markings on the side of the mounting base for intuitive observation, it adapts to welding sheet metal parts at different angles, which helps to expand the applicability of the equipment. During the clamping operation of the parts, the bracket supports the end of the sheet metal part to prevent slippage, and the screw drives the pressure block and the protrusion to clamp the workpiece. At the same time, the rubber pad enhances the friction. In addition, by setting the operating structure of the clamping component away from the laser welding gun, sufficient space is reserved to avoid collisions between the two clamps and the laser welding gun when the angle between them is small, ensuring smooth welding operation.

[0018] 3. When the workpiece is flipped, the rotating shaft drives the cam to rotate, and the convex part pushes the roller seat and the top rod to move the top plate upward. The linkage welding components avoid the collision, thereby eliminating the hidden danger of collision and interference between the workpiece and the laser welding gun during the workpiece flipping process. This further enhances the safety of the laser welding equipment during use. At the same time, the laser welding gun moves upward on its own through the mechanical linkage structure to avoid the collision without the need for additional system control, thereby improving the convenience of operation. After flipping, the cam convex part disengages, the compression spring pushes the top plate to automatically reset, the guide rod ensures the reset accuracy, and the shock-absorbing pad buffers the impact, which helps to extend the service life of the equipment.

[0026] Please see Figures 1 to 3This invention provides a technical solution: a convenient laser welding device, including a frame 1 and a tilting assembly 4. A top plate 2 is provided on the top of the frame 1, and a welding assembly 3 is provided in the middle of the top plate 2. The welding assembly 3 includes a motor 301. The motor 301 is mounted on one side of the middle of the top plate 2, and the output shaft of the motor 301 is connected to a lead screw 302. A movable seat 303 is sleeved on the outer side of one end of the lead screw 302, and a light rod 304 is slidably connected to the inner side of one end of the movable seat 303. The light rod 304 is fixedly connected to the top plate 2. An electric telescopic rod 305 is provided at the bottom of the movable seat 303, and a laser welding gun 306 is provided at the bottom of the electric telescopic rod 305. The tilting assembly 4 is located at the lower part of the frame 1 and includes an electric cylinder 401. An electric cylinder 401 is installed, and a T-shaped plate 402 is fixedly connected to one end of the electric cylinder 401. The T-shaped plate 402 is slidably connected to the frame 1. A drive plate 403 is installed at both ends of the T-shaped plate 402. A round hole is provided at the upper end of the drive plate 403. A drive column 404 is provided on the wall of the round hole at the upper end of the drive plate 403. A rotating shaft 405 is slidably connected in the round hole at the upper end of the drive plate 403. The rotating shaft 405 is rotatably connected to the frame 1. A guide groove 406 is provided on the outer side of the rotating shaft 405. The guide groove 406 is composed of straight grooves on both sides and a slanted groove in the middle. The drive column 404 is slidably connected to the rotating shaft 405 through the guide groove 406. A mounting base 407 is fixed at the end of the rotating shaft 405 away from the drive plate 403. A clamping assembly 5 is connected to one end of the mounting base 407.

[0027] This laser welding equipment can weld together two plate-shaped workpieces.

[0028] The specific operation is as follows: after the workpiece is clamped and positioned, the height of the laser welding gun 306 is finely adjusted by the electric telescopic rod 305. During welding, the motor 301 will also drive the lead screw 302 to rotate, so that the moving seat 303 slides along the outside of the light rod 304, which allows the laser welding gun 306 to move and weld along the splice seam of the workpiece.

[0029] Furthermore, after welding, since the extended end of the electric cylinder 401 is rigidly connected to the drive plate 403 via the T-shaped plate 402, the extension distance of the electric cylinder 401 determines the moving distance of the T-shaped plate 402. The moving distance of the T-shaped plate 402, in turn, determines the position of the drive column 404 within the guide groove 406. Therefore, simply activating the electric cylinder 401 to move the T-shaped plate 402 allows the drive column 404 inside the drive plate 403 to slide within the guide groove 406. Since the guide groove 406 consists of straight grooves, inclined grooves, and straight grooves from left to right, when the drive column 404 slides to the inclined groove portion of the guide groove 406, it can drive the rotating shaft 405 to rotate. Depending on the position of the drive column 404 within the inclined groove portion of the guide groove 406 from left to right, its rotatable angle range is 0-180°. When the drive column 404 slides to the right of the guide groove 406... When the straight groove section is reached, the rotation direction of the rotating shaft 405 will be automatically locked, which helps to improve the stability of welding after flipping. With the setting of two drive plates 403, the two drive plates 403 will move from left to right at the same time, so that the rotating shafts 405 on both sides can rotate synchronously to apply force, avoiding external forces from interfering with the workpiece. Moreover, the welding point of the workpiece and the axis of the rotating shaft 405 are located on the same horizontal plane, so the height change of the welding point after flipping is small, reducing the adjustment time of the electric telescopic rod 305. At the same time, the position of the workpiece will also move, so that the workpiece will move to the side of the laser welding gun 306 near the welding wire after flipping. Therefore, the laser welding gun 306 can continue to move to complete the welding of the back of the workpiece without having to reset the laser welding gun 306 before welding, thereby reducing operation steps, making it more convenient, and improving the efficiency of workpiece welding.

[0030] Please see Figure 4 and Figure 5The clamping assembly 5 includes an electric push rod 501. The electric push rod 501 is mounted on the lower end of one side of the mounting base 407, and a guide plate 502 is fixed to the telescopic end of the electric push rod 501. The guide plate 502 is slidably connected to the mounting base 407. An elongated hole is provided at the upper end of the guide plate 502, and a sliding column 503 is slidably connected within the wall of the elongated hole at the upper end of the guide plate 502. A slider 504 is fixed to one side of the sliding column 503, and the slider 504 has an I-shaped cross-section. A limiting groove 505 is provided at the upper part of the mounting base 407, and the limiting groove 505 is arc-shaped. The slider 504... 04 is slidably connected to the mounting base 407 via the limiting groove 505. A clamping seat 506 is installed on one side of the slider 504, and a screw 507 is threadedly connected to the upper end of the clamping seat 506. A pressure block 508 is rotatably connected to one end of the screw 507, and a protrusion 509 is slidably connected to the lower end of the pressure block 508. The protrusion 509 is triangular, and a clamping plate 510 is fixed to the bottom of the protrusion 509. The clamping plate 510 is rotatably connected to the clamping seat 506, and a rubber pad 511 is provided at one bottom end of the clamping plate 510. A bracket 6 is installed in the middle of the lower end of the frame 1, and the bracket 6 is T-shaped.

[0031] The specific operation is as follows: starting the electric push rod 501 controls the height of the guide plate 502, which allows the sliding column 503 to drive the slider 504 to slide inside the limit groove 505, thereby changing the tilt angle of the mounting base 407. The pre-set marking scale on the mounting base 407 makes it easy to observe the adjusted angle, thus enabling the butt welding of sheet metal parts at different angles, which helps to improve the application range of the equipment.

[0032] Meanwhile, when clamping sheet metal parts, simply place them on the clamping base 506. At this time, the bracket 6 can support and limit the end of the sheet metal to prevent slippage, making placement more convenient. Then, simply rotate the screw 507 to drive the pressure block 508 to squeeze the protrusion 509, so that the clamping plate 510 can clamp the sheet metal. The rubber pad 511 increases the friction during clamping. In addition, by setting the operating structure of the clamping assembly 5 at one end away from the laser welding gun 306, there is a large space around the laser welding gun 306, which avoids collision with the laser welding gun 306 when the angle formed by the two clamping bases 506 is small, thus avoiding affecting the normal welding operation.

[0033] Please see Figure 2 and Figure 6The upper two sides of the frame 1 are provided with avoidance components 7. The avoidance components 7 include cams 701. The outer side of the rotating shaft 405 near the mounting base 407 is fixed with cams 701. The top of cams 701 is provided with roller seats 702. The top of roller seats 702 is provided with push rods 703. The push rods 703 are slidably connected with the protrusions with round holes on both sides of the upper part of the frame 1. The top of push rods 703 is fixedly connected with the bottom of top plate 2. The top of the frame 1 is symmetrically provided with guide rods 704. The guide rods 704 are slidably connected with top plate 2. The outer side of the upper end of the guide rods 704 is sleeved with compression springs 705. The compression springs 705 are tightly fitted with top plate 2. The outer side of the lower end of the guide rods 704 is provided with shock-absorbing pads 706.

[0034] The specific operation is as follows: During the workpiece flipping process, its rotation center will be located on one side of the workpiece, so the other side of the workpiece will move upward and make a circular motion. At this time, the rotating shaft 405 will also drive the cam 701 to rotate synchronously. When the roller seat 702 moves towards the convex part of the cam 701, it will drive the top plate 2 to move upward through the push rod 703. Therefore, during the flipping process, the welding assembly 3 will also move upward synchronously. Compared with the existing welding equipment, which requires the welding torch to move upward to avoid obstacles using an electronic control system during the welding process, but when a hardware or software failure occurs, the problem of collision due to untimely avoidance will occur. This application eliminates the avoidance structure controlled by the system when flipping the workpiece and adopts a different approach. The mechanical linkage structure eliminates the risk of collision and interference between the workpiece and the laser welding gun 306 during the workpiece flipping process, further enhancing the safety of the laser welding equipment. At the same time, the laser welding gun 306 moves upward automatically to avoid collisions through the mechanical linkage structure, without the need for additional system control, thereby improving the convenience of operation. After flipping, when the roller seat 702 moves away from the protrusion on the cam 701, the compression spring 705 pushes the top plate 2 to move downward under the guidance of the guide rod 704, so that the top plate 2 can automatically reset after avoiding collisions. The shock-absorbing pad 706 reduces the impact force between the top plate 2 and the frame 1, which helps to extend the service life of the equipment.

[0035] In summary, this easy-to-operate laser welding equipment is used by first controlling the height of the guide plate 502 according to the angle of the product through the electric push rod 501. This allows the sliding column 503 to drive the slider 504 to slide inside the limiting groove 505, thereby changing the tilt angle of the mounting base 407. The marking scale on the mounting base 407 is pre-set for easy observation. Then, the sheet metal parts are placed on the clamping base 506. At this time, the bracket 6 can support and limit the end of the plate to prevent slippage, making placement more convenient. After that, simply rotate the screw 507 to drive the pressure block 508 to press the protrusion 509, which allows the clamping plate 510 to clamp the plate. The rubber pad 511 increases the friction during clamping.

[0036] Next, the height of the laser welding gun 306 is finely adjusted by the electric telescopic rod 305. During the welding process, the motor 301 will also drive the lead screw 302 to rotate, so that the moving seat 303 slides along the outside of the light rod 304, which allows the laser welding gun 306 to move and weld along the splice seam of the workpiece.

[0037] Then, after welding one side is completed, the electric cylinder 401 is activated, causing it to move the T-shaped plate 402. This allows the drive column 404 inside the drive plate 403 to slide inside the guide groove 406. When the drive column 404 is located in the inclined section of the guide groove 406, it drives the rotating shaft 405 to rotate. Simultaneously, during the process of flipping the workpiece, its rotation center will be located on one side of the workpiece, so the other side of the workpiece will move upward and make a circular motion. At this time, the rotating shaft 405 will also drive the cam 701 to rotate synchronously. When the roller seat 702 moves towards the cam... When the protrusion of 701 is reached, the top plate 2 will be moved upward by the push rod 703. Therefore, during the flipping process, the welding component 3 will also move upward synchronously, thereby eliminating the hidden danger of collision and interference between the workpiece and the laser welding gun 306 during the workpiece flipping process. After flipping, when the roller seat 702 moves away from the protrusion on the cam 701, the compression spring 705 will push the top plate 2 to move downward under the guidance of the guide rod 704, so that the top plate 2 can automatically reset after avoiding the collision, and the shock-absorbing pad 706 will reduce the impact force between the top plate 2 and the frame 1.

[0038] Finally, when the drive column 404 is located in the straight groove of the guide groove 406, it will automatically lock the rotation direction of the rotating shaft 405, which helps to improve the stability of welding after flipping. At the same time, the position of the workpiece will also move to the side of the laser welding gun 306 closer to the welding wire. Therefore, after finely adjusting the height by the electric telescopic rod 305, the laser welding gun 306 can continue to move to complete the welding of the back of the workpiece.
