Description

Technical Field

[0001] This utility model belongs to the field of skeleton welding technology, specifically relating to a robot for welding the skeleton of a decorative lantern. Background Technology

[0002] A lantern frame welding robot is an automated device specifically designed for manufacturing lantern frames. It primarily welds metal or plastic frames to support the lantern's shape. Through automation, it improves production efficiency, ensures welding quality, and reduces labor costs.

[0003] A search revealed that CN216607708U discloses a frame welding device for building construction. This device employs two guide and positioning clamps, with a clamping disc at the bottom of each clamp for holding the frame. The clamping discs are flexibly removable to accommodate different specifications of frames of varying diameters. The two clamps are quickly fitted onto the corresponding frames using the clamping discs, and the movement between the clamps is controlled to ensure rapid and accurate alignment of the clamped frame interfaces for welding. However, this device requires multiple motors to perform the clamping and docking operations on the frame, resulting in poor adjustment performance and making it unsuitable for complex lamp frame welding.

[0004] To address this issue, a robot for welding the frame of colored lanterns was designed. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a welding robot for a decorative lantern frame. In use, the plastic frame is inserted into the inner side of a wear-resistant clamping plate. Depending on the shape of the plastic frame, the stepper motor on the top of the positioning seat is activated via the control terminal. The motor shaft drives the drive shaft to rotate. Because two sets of limiting rods pass through through holes in the movable bracket, the movable bracket cannot follow the movement. With the cooperation of the threaded surface of the bidirectional screw and the threaded groove inside the movable bracket, the two sets of movable brackets can approach each other. During this process, the outer wear-resistant clamping plate, along its inclined surface perpendicularly, drives the slider to pull and compress the springs on both sides. Under the elastic support of the springs, the frame abutting against the inner side of the two sets of wear-resistant clamping plates is subjected to pressure from both sides, thereby maintaining the stability of the frame and facilitating subsequent welding.

[0006] During the docking process, only the middle tightener of the turnbuckle needs to be turned by hand, so that the two sets of hook screws pull the positioning seats relative to each other through the fixed ropes. The positioning seats slide freely on the inside of the operating table through the sliding friction between the limiting groove at the bottom and the guide rail, thereby completing the docking operation of the two sets of skeletons. This eliminates the need for the traditional operation process of clamping and docking through multiple motors, thus simplifying the equipment and saving production costs.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a colored lantern frame welding robot, comprising an operating table, a guide rail, a positioning seat, a stepper motor, a bidirectional screw, a movable bracket, a wear-resistant clamp, and welding components. The guide rail is fixedly connected inside the operating table, the positioning seat is slidably connected to the outside of the guide rail, the stepper motor is threadedly connected to the inside of the positioning seat, one end of the bidirectional screw is fixedly connected to the motor shaft of the stepper motor via a coupling, the movable bracket is threadedly sleeved on the outside of the bidirectional screw, and the wear-resistant clamp is slidably connected to the outside of the movable bracket.

[0008] As a preferred embodiment of the decorative lantern frame welding robot of this utility model, the inner side of the wear-resistant clamping plate is further provided with a slider and a compression spring. The slider is fixedly connected to the inner side of the wear-resistant clamping plate, and the two sides of the compression spring are respectively fixedly connected to the opposite side surfaces of the slider and the movable bracket.

[0009] As a preferred embodiment of the decorative lantern frame welding robot of this utility model, a turnbuckle and a fixing rope are also provided on the opposite side of the positioning seat, and the two sides of the fixing rope are respectively wound and connected to the hook end of the turnbuckle and the outer wall surface of the positioning seat.

[0010] As a preferred embodiment of the decorative lantern frame welding robot of this utility model, the bottom of the positioning seat is provided with a limiting groove that matches the top size of the guide rail.

[0011] As a preferred embodiment of the lantern frame welding robot of this utility model, the top opposite side surface of the positioning seat is also fixedly connected with a limit rod.

[0012] As a preferred embodiment of the lantern frame welding robot of this utility model, the bottom of the movable bracket is respectively provided with threaded grooves and through holes that are adapted to the size of the bidirectional screw and the limiting rod.

[0013] As a preferred embodiment of the lantern frame welding robot of this utility model, the welding assembly includes a fixed bracket and a robotic laser welding machine. The fixed bracket is fixedly connected to the outside of the operating table, and the robotic laser welding machine is threadedly connected to the top of the fixed bracket and is used for welding the lantern frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, with the screw thread surface of the bidirectional screw and the screw thread groove built into the movable bracket, the two sets of movable brackets can approach each other. During this process, the outer wear-resistant clamping plate drives the slider to pull the spring on both sides along the vertical direction of its inclined surface. Under the elastic support of the spring, the skeleton that abuts against the inner side of the two sets of wear-resistant clamping plates is subjected to pressure from both sides, thereby maintaining the stability of the skeleton and facilitating subsequent welding.

[0016] 2. In this utility model, only the middle tightener of the turnbuckle needs to be rotated by hand, so that the two sets of hook screws pull the positioning seats relative to each other through the fixed ropes. The positioning seats slide freely on the inside of the operating table through the sliding friction between the limiting groove at the bottom and the guide rail, thereby completing the docking operation of the two sets of frames. This eliminates the traditional operation process of clamping and docking through multiple motors, thus simplifying the equipment and saving production costs. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 As shown:

[0027] A welding robot for decorative lantern frames, as disclosed in CN216607708U, employs two guide and positioning clamping plates. Each clamping plate has a clamping disc at its bottom for holding the frame. The clamping discs can be flexibly disassembled and replaced with different specifications to accommodate frames of different diameters. The two clamping plates are quickly fitted and clamped onto the corresponding frames using the clamping discs. The movement and adjustment between the clamping plates are controlled to ensure that the clamped frame interfaces are quickly and accurately aligned for welding. However, this device requires multiple sets of motors to perform the clamping and docking operations on the frame, resulting in poor adjustment performance and making it unsuitable for complex lantern frame welding.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown:

[0029] In an optional embodiment, the system includes an operating platform 1, a guide rail 2, a positioning seat 3, a stepper motor 4, a bidirectional screw 5, a movable bracket 6, a wear-resistant clamping plate 7, and a welding assembly 8. The guide rail 2 is fixedly connected to the inside of the operating platform 1, the positioning seat 3 is slidably connected to the outside of the guide rail 2, the stepper motor 4 is threadedly connected to the inside of the positioning seat 3, one end of the bidirectional screw 5 is fixedly connected to the motor shaft of the stepper motor 4 via a coupling, the movable bracket 6 is threadedly fitted onto the outside of the bidirectional screw 5, and the wear-resistant clamping plate 7 is slidably connected to the outside of the movable bracket 6. A slider 9 and a compression spring 10 are also provided on the inside of the wear-resistant clamping plate 7. The slider 9 is fixedly connected to the inside of the wear-resistant clamping plate 7, and the two sides of the compression spring 10 are fixedly connected to the opposite side surfaces of the slider 9 and the movable bracket 6, respectively.

[0030] In this implementation scheme: the plastic skeleton can be inserted into the inner side of the wear-resistant clamping plate 7. Depending on the shape of the plastic skeleton, during operation, the stepper motor 4 on the top of the positioning seat 3 can be started through the control terminal. The motor shaft drives the drive shaft to rotate. Since the two sets of limit rods 14 pass through the through hole 16 through the movable bracket 6, the movable bracket 6 cannot follow. With the cooperation of the threaded surface of the bidirectional screw 5 and the screw of the built-in threaded groove 15 of the movable bracket 6, the two sets of movable brackets 6 can approach each other. During this process, the outer wear-resistant clamping plate 7 drives the slider 9 to pull the compression spring 10 to both sides along the vertical direction of its inclined surface 17. Under the elastic support of the spring, the skeleton that is against the inner side of the two sets of wear-resistant clamping plates 7 is subjected to pressure from both sides, thereby maintaining the stability of the skeleton and facilitating subsequent welding.

[0031] It should be noted that: the bidirectional screw 5 has two sets of screw threads that are opened in opposite directions along its outer edge, and the threaded grooves 15 of the two sets of movable brackets 6 are respectively matched with the screw threads connected to them, so that the bidirectional screw 5 can smoothly drive the two sets of movable brackets 6 to move towards or away from each other when rotating.

[0032] Furthermore:

[0033] like Figure 1 , Figure 2 and Figure 5 As shown:

[0034] In an optional embodiment: a turnbuckle 11 and a fixing rope 12 are also provided on the opposite side of the positioning seat 3. The two sides of the fixing rope 12 are respectively wound and connected to the hook end of the turnbuckle 11 and the outer wall surface of the positioning seat 3. The bottom of the positioning seat 3 is provided with a limiting groove 13 that matches the top size of the guide slide rail 2. The bottom of the positioning movable bracket 6 is respectively provided with a threaded groove 15 and a through hole 16 that matches the size of the bidirectional screw 5 and the limiting rod 14. The welding assembly 8 includes a fixed bracket 81 and a robotic laser welding machine 82. The fixed bracket 81 is fixedly connected to the outside of the operating table 1, and the robotic laser welding machine 82 is threadedly connected to the top of the fixed bracket 81 and is used for welding the frame of the lantern frame.

[0035] In this embodiment: During the docking process, only the middle tightener of the turnbuckle 11 needs to be turned by hand, so that the two sets of hook screws pull the positioning seat 3 relative to each other through the fixed rope 12. The positioning seat 3 can slide freely inside the operating table 1 through the sliding friction between the limiting groove 13 opened at the bottom and the guide rail 2, thereby completing the docking operation of the two sets of skeletons. This eliminates the traditional operation process of clamping and docking through multiple sets of motors, thereby simplifying the equipment and saving production costs.

[0036] It should be noted that the fixed bracket 81 is installed on the outer side of the upper diagonal of the movable bracket 6. The robotic laser welding machine 82, combined with AI and machine learning, enables adaptive welding, which can adapt to the welding of plastic frames for colored lights with more complex shapes and materials.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
