Description

Technical Field

[0001] This invention relates to the field of robotic workstation technology, specifically to a 3D laser robotic welding workstation for mesh grids. Background Technology

[0002] 3D laser robots can work quickly and accurately. Welding heads are installed at the robot's working end, enabling subsequent welding operations. In workstation applications, corresponding robots and workpiece fixing components are used.

[0003] In existing technologies, when using robots for welding, the overall shape of the mesh grid limits the robot's ability to weld in dead angles when welding the vertical inner wall of the mesh grid at a distance, resulting in poor welding quality. Furthermore, when encountering large mesh grids, the robot's position is limited, often requiring manual translation by the operator, which is inconvenient. Therefore, a device is needed that can synchronously adjust the angle of the mesh grid according to the robot's welding angle and automatically move the mesh grid when the robot needs to weld at a distance, in order to avoid poor welding quality and inconvenience.

Several rotating platforms are evenly distributed around the supporting platform. An L-shaped fixing frame is provided on the side of the rotating platform away from the center of the supporting platform. An L-shaped locking rod is slidably mounted on the L-shaped fixing frame. The side of the L-shaped locking rod away from the supporting platform is connected to the output end of the first electric push rod. The bottom of the L-shaped locking rod away from the end of the first electric push rod has a protrusion that can penetrate the L-shaped fixing frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] In this invention, the mesh grid is laid flat on the supporting component, and then a laser robot performs welding on the mesh grid. When the laser robot is at the extreme positions of the mesh inner wall around the welding area, the supporting component is slightly deflected in the direction of the robot's swing by the laser robot's swing, which facilitates the robot to weld the vertical surface of the mesh grid inner wall at a distance. When the robot needs to weld the outer side of the extreme welding area, the robot's deflection angle increases, which in turn moves the supporting component and the entire mesh grid towards the robot, thus facilitating the robot's welding work. This avoids the welding blind spot that may occur when the robot is welding the vertical surface of the mesh grid inner wall at a distance due to its limited displacement distance, thereby improving the welding quality. At the same time, it avoids the need for operators to manually move the mesh grid when dealing with a large area, thus improving the convenience of this device.

[0014] In this invention, by using the supporting components and other parts in cooperation, the laser robot can be tilted to place the platform when working on either side, thereby facilitating the welding work of the laser robot and improving the practicality of the device.

[0015] In this invention, the combined use of control devices and tilting components avoids the welding blind spots that can easily occur when the robot welds the vertical inner wall of a distant mesh grid due to its limited displacement distance, thus improving welding quality. It also avoids the need for manual translation of the mesh grid when dealing with large areas, improving the device's convenience. Furthermore, the addition of lifting rods and telescopic toothed rods allows the device to adapt to mesh grids of different specifications, further enhancing its applicability.

[0016] In this invention, by setting a movable limiting plate, the position of the mesh grid will not be affected when the placement frame is tilted, thereby increasing the stability of the device during operation. Attached Figure Description

[0036] In this embodiment, as Figures 8 to 13As shown, the mating assembly 51 includes a control console 511 located above the placement frame 45. The four corners of the control console 511 are movably connected to the movable base 1 via vertical lifting rods 512. A drive platform 513 is provided on the top of the control console 511. A control arm 514 for controlling the laser robot 7 is located at the bottom center of the middle part of the control console 511. The tail of the laser robot 7 is connected to the output end of the control arm 514. A drive bevel gear 515 is provided at the rotation point of the control arm 514.

The bottom of the drive platform 513 is provided with a second control toothed rod 523 that can mesh with the moving bevel gear 520. The second control toothed rod 523 is slidably engaged with the drive platform 513. The two ends of the second control toothed rod 523 are connected to the top of the other two telescopic toothed rods 522. The side ends of the first control toothed rod 521 and the second control toothed rod 523 are provided with a first infrared sensor 524 that can control the operation of the first electric push rod 35 at the corresponding position according to the direction of movement.

[0037] The interrupted assembly 6 includes a stabilizer 61 located on top of the drive platform 513. A second electric push rod 62 is mounted on the stabilizer 61. The output end of the second electric push rod 62 is connected to the top of the sliding shaft 518.

When the control arm 514 rotates 90 degrees, the second infrared sensor 63 drives the second electric push rod 62 to operate.

[0038] The tilting assembly 8 includes four arc-shaped plates 81 located on the bottom of the placement frame 45. Each arc-shaped plate 81 has a flipping frame 82 on its side end. The bottom of the flipping frame 82 is connected to the top of the control table 21. The top of the flipping frame 82 is rotatably connected to a flipping plate 83 that cooperates with the arc-shaped plate 81. The two ends of the flipping plate 83 are movably connected to the top of the control table 21 through tension springs 84. A rotating extrusion member 85 is provided below the flipping plate 83. The rotating extrusion member 85 has an arc-shaped protrusion 86. The middle part of the rotating extrusion member 85 is rotatably engaged with the flipping frame 82 through a central shaft 87. A mating gear 88 is provided on the side of the flipping frame 82 away from the rotating extrusion member 85. The center of the mating gear 88 is rotatably mounted on the central shaft 87 through a one-way bearing. The bottom of the mating gear 88 can mesh with the toothed end of the telescopic toothed rod 522.

[0039] In this embodiment, as Figure 1 As shown, the top of the placement rack 45 is provided with slidable locking limit plates 89 on all four sides.

[0040] The invention provides the following usage method and advantages: A 3D laser robot welding workstation for mesh grids operates as follows:

[0041] like Figures 1 to 13 As shown, when the first electric push rod 35 on one side drives the L-shaped clamping rod 34 to move along the L-shaped fixing frame 33, it can drive the protrusion 36 to be locked into the rotating groove 48 on the adjacent rotating roller 46, thereby fixing the rotating roller 46 on one side. Then, by controlling the placement frame 45 to flip up on the opposite side, it can be rotated along the limiting rotating roller 46 as the axis through the rotating frame. Through the cooperation of the second cross shaft 43 and the first cross shaft 39, under the action of the connecting rod 42 and the hinge rod 41, the placement frame 45 can deflect along the axis after the rotating roller 46 on either side is limited by the protrusion 36. This allows the laser robot 7 to tilt the placement table when working on either side, thereby facilitating the welding work of the laser robot 7 and improving the practicality of the device.

[0042] When the laser robot 7 deflects to one side, the control arm 514 and the drive bevel gear 515 drive the linkage bevel gear 516 to deflect. With the cooperation of the linkage shaft 517 and the cross 519, the moving bevel gear 520 rotates in the same direction, which in turn drives the first control toothed rod 521, which meshes with it, to slide. This causes the telescopic toothed rod 522 to move synchronously in the opposite direction to the deflection of the laser robot 7. When the first control toothed rod 521 slides, according to its sliding direction, the first infrared sensor 524 drives the first electric push rod 35, which moves in the same direction as the sliding rod. This, in turn, drives the telescopic toothed rod 522 to rotate the meshing gear 88. The first spring telescopic rod 22 is compressed by the connecting plate 23, and the rotating extrusion member 85 is deflected by the central shaft 87, causing the arc-shaped protrusion 86 to abut against the bottom of the flip plate 83. The flip plate 83 moves upward under the action of the tension spring 84, and then the arc-shaped plate 81 drives the placement frame 45 to tilt upward in the direction of the laser robot 7's deflection. When the laser robot 7 completes its maximum working distance, the control arm 514 continues to deflect, increasing the tilt angle. This, through the drive bevel gear 515, increases the rotation angle of the rotating extrusion member 85, causing the arc-shaped protrusion 86 to disengage from the flip plate 83. The flip plate 83 then resets under the action of the tension spring 84. At this time, the first spring... The compression rod 22 is fully compressed, thereby causing the control table 21 to shift as a whole under the action of the second spring telescopic rod 24 via the connecting plate 23. This moves the part of the mesh grid outside the working range of the laser robot 7 into its working range. After the welding work is completed, the control arm 514 drives the control table 21 to reset. During the reset process, the rotating extrusion part 85 does not rotate through the one-way bearing. Then, the same working steps are used to weld the areas in opposite directions. After the welding of both sides is completed, the control arm 514 rotates 90 degrees, and the second electric push rod 62 is driven by the second infrared sensor 63, thereby causing the sliding shaft 518 to move upward along the linkage shaft 517, through the cross 519. The moving bevel gear 520 disengages from the first control toothed rod 521 and engages with the second control toothed rod 523. During its deflection welding operation, the tilting of the placement frame 45 and the offset of the control table 21 are achieved according to its deflection angle. This avoids the welding blind zone that may occur when the robot welds the vertical surface of the inner wall of the distant mesh grid due to its limited displacement distance, thereby improving the welding quality. At the same time, it avoids the need for workers to manually move the mesh grid position when facing a large area of ​​mesh grid, thus improving the convenience of this device. Furthermore, the lifting rod 512 and the telescopic toothed rod 522 enable this device to adapt to mesh grids of different specifications, further improving the applicability of this device.

[0043] By setting a movable limiting plate 89, the position of the grid is not affected when the placement frame 45 is tilted, thereby increasing the stability of the device during operation.
