Description

Technical Field

[0001] This utility model relates to the field of welding robot technology, specifically a sign welding robot. Background Technology

[0002] Welding robots are industrial robots that perform welding (including cutting and spraying). With the development of electronic technology, computer technology, numerical control and robotics technology, automatic welding robots have been used in production since the 1960s, and their technology has become increasingly mature. Signs, as the name suggests, are signs used to make identifications. They contain text, pictures and other content to indicate directions and provide warnings. Signs also require the assistance of welding robots in the production process.

[0003] However, existing welding robots, such as the one with technical disclosure number CN219598467U, only have a single welding mechanism. Therefore, during welding, they can only perform welding operations on a single product part. In the process of mass production, the production efficiency of a single welding mechanism is low and cannot meet the production needs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of low production efficiency in existing technologies by providing a sign welding robot.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sign welding robot, comprising a base and a robotic arm. A rotating seat is movably connected to the top of the base, and the robotic arm is fixedly connected to the rotating seat. A mounting bracket is fixedly connected to the front end of the robotic arm, and several welding components are arranged on the mounting bracket. Fixed plates are connected to the top and bottom of the mounting bracket. The several welding components are evenly distributed on the two fixed plates and arranged linearly on the mounting plate. The welding components include a mounting plate, a welding torch, and a vacuum suction cup. The welding torch is connected to the fixed plate through the mounting plate, and the vacuum suction cup is located on the front side of the mounting plate, and an air pump is connected to the vacuum suction cup.

[0006] The aforementioned mounting bracket includes a fixed block fixedly connected to the front end of the robotic arm. The fixed block has a through groove, and two cross-arranged movable plates are inserted into the through groove. The two movable plates are movably connected to each other, and the movable plates are movably connected to the fixed block.

[0007] As described above, connecting blocks are movably connected to both ends of the two movable plates, and linear guide rails are fixedly connected to both fixed plates. The connecting blocks are slidably connected to the linear guide rails, and a first cylinder is fixedly connected between the two connecting blocks located at the top.

[0008] As described above, an electric slide rail is fixedly connected to one side of the fixed plate opposite to the fixed block, and the mounting plate is fixedly connected to the slider of the electric slide rail.

[0009] As described above, the vacuum suction cup is fixedly connected to the front side of the mounting plate, the air pump is fixedly connected to the mounting plate, and there is an air pipe at the joint between the air pump and the vacuum suction cup.

[0010] As described above, the mounting plate is L-shaped, and a slot is provided on the front side of the mounting plate. A second cylinder is fixedly connected to the mounting plate, and the welding gun is fixedly connected to the telescopic end of the second cylinder.

[0011] Compared with existing technologies, this sign welding robot has the following advantages:

[0012] I. This utility model improves welding efficiency by setting up a mounting bracket and mounting multiple welding components with welding guns on the mounting bracket, with the multiple welding components being independent of each other, so that the robotic arm can handle the welding operations of multiple signs at the same time.

[0013] II. This utility model uses a vacuum suction cup to adsorb and fix the nameplate. At the same time, a second cylinder is set on the welding assembly, and the welding gun is fixed to the extension end of the second cylinder. The welding gun is pushed and retracted by the second cylinder, so that the connection between the welding gun and the nameplate is stable, thereby ensuring the accuracy and consistency of welding multiple sets of welding assemblies.

[0014] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0020] 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.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a sign welding robot, including a base 1 and a robotic arm 2. A rotating seat is movably connected to the top of the base 1, and the robotic arm 2 is fixedly connected to the rotating seat. A mounting bracket 3 is fixedly connected to the front end of the robotic arm 2, and several sets of welding components 4 are arranged on the mounting bracket 3. Fixed plates 5 are connected to the top and bottom of the mounting bracket 3. Several sets of welding components 4 are evenly distributed on the two fixed plates 5 and are linearly arranged on the mounting plate 401. The welding components 4 include the mounting plate 401, a welding torch 402, and a vacuum suction cup 404. The welding torch 402 is connected to the fixed plate 5 through the mounting plate 401. The vacuum suction cup 404 is arranged on the front side of the mounting plate 401, and an air pump 405 is connected to the vacuum suction cup 404.

[0022] According to the overall structure of the device, when in use, the device is connected to an external power source, the robotic arm 2 is started, the robotic arm 2 moves above the sign and the welding gun 402 is aimed at the sign. Then the robotic arm 2 moves the mounting bracket 3 close to the sign, so that the vacuum suction cup 404 contacts the sign. The air pump 405 extracts the air between the vacuum suction cup 404 and the sign, so that the vacuum suction cup 404 adsorbs and fixes the sign. Then the welding gun 402 is started to weld the sign.

[0023] like Figure 2-3As shown, the mounting bracket 3 includes a fixed block 301 fixedly connected to the front end of the robotic arm 2. The fixed block 301 has a through groove, and two cross-arranged movable plates 302 are inserted into the through groove. The two movable plates 302 are movably connected to each other and to the fixed block 301. Connecting blocks 303 are movably connected to both ends of the two movable plates 302. Linear guide rails 6 are fixedly connected to both fixed plates 5, and the connecting blocks 303 are slidably connected to the linear guide rails 6. A first cylinder 304 is fixedly connected between the two connecting blocks 303 located at the top. An electric slide rail 7 is fixedly connected to the side of the fixed plate 5 opposite to the fixed block 301. The mounting plate 401 is fixedly connected to the slider of the electric slide rail 7.

[0024] The mounting bracket 3 is composed of two intersecting movable plates 302 and a fixed block 301. The extension and retraction of the first cylinder 304 connected between the two movable plates 302 drives the deflection between the two movable plates 302, thereby driving the movement of the upper and lower fixed plates 5. This adjusts the spacing of the welding guns 402 on different fixed plates 5. The slider is driven by the electric slide rail 7 to move, thereby driving the mounting plate 401 and the welding guns 402 to move, thereby adjusting the spacing of the welding guns 402 on the same fixed plate 5. This allows the device to be used for welding at different positions on different sized nameplates.

[0025] like Figure 4 As shown, the vacuum suction cup 404 is fixedly connected to the front side of the mounting plate 401, the air pump 405 is fixedly connected to the mounting plate 401, and there is an air pipe at the joint between the air pump 405 and the vacuum suction cup 404. The mounting plate 401 is L-shaped, and a slot is opened on the front side of the mounting plate 401. The second cylinder 403 is fixedly connected to the mounting plate 401, and the welding torch 402 is fixedly connected to the telescopic end of the second cylinder 403.

[0026] By setting a vacuum suction cup 404 on the front side of the mounting plate 401, the vacuum suction cup 404 first contacts the nameplate. Then, the air pump 405 extracts the air between the vacuum suction cup 404 and the nameplate during welding, so that the vacuum suction cup 404 adsorbs and fixes the nameplate. After the nameplate is fixed by the vacuum suction cup 404, the second cylinder 403 pushes the welding gun 402 to move and weld the nameplate. After welding, the second cylinder 403 retracts and drives the welding gun 402 to retract. At the same time, the air pump 405 sends air into the vacuum suction cup 404, so that the vacuum suction cup 404 releases the nameplate. This ensures accurate and stable contact and separation between the welding gun 402 and the weld point, and ensures the precision and consistency of welding.

[0027] Working principle: When in use, connect the device to an external power source, start the robotic arm 2, move the robotic arm 2 above the sign, and point the welding gun 402 toward the sign. According to the size of the sign and the welding position, start the first cylinder 304. The first cylinder 304 extends and retracts, causing the two movable plates 302 to deflect, thereby adjusting the distance between the two fixed plates 5. At the same time, the electric slide rail 7 drives the slider to move, adjusting the distance between the welding guns 402 on the same fixed plate 5, so that the position of the welding gun 402 corresponds to the welding position. Then, the robotic arm 2 moves the mounting bracket 3 close to the sign, so that the vacuum suction cup 404 contacts the sign. The air pump 405 extracts the air between the vacuum suction cup 404 and the sign, so that the vacuum suction cup 404 adsorbs and fixes the sign, ensuring precise and consistent welding. Then, start the welding gun 402, and push the welding gun 402 to weld the sign through the second cylinder 403.
