Description

Technical Field

[0001] This application relates to the field of welding technology, and in particular to a connection device for a movable welding robotic arm. Background Technology

[0002] Mobile welding robotic arms are widely used in industrial plants, high-rise buildings, airport terminals, railway stations, thermal power plants, bridges, and other fields where construction sites are fast-paced and complex. The integrated flexible collaborative robot from Luoshi enables efficient on-site transport and deployment, meeting the welding needs of various construction sites.

[0003] During welding, the welding robotic arm is fixed to the trolley with bolts. The flexible movement of the robotic arm facilitates the welding equipment to perform flexible welding, and the movement of the trolley allows the welding robotic arm to be moved to the appropriate position for welding.

[0004] Existing welding robotic arms use a flexible robotic arm to drive the welding head to weld the joint. However, when the mobile trolley cannot reach the designated position, workers need to loosen multiple bolts to disassemble the welding robotic arm. Disassembly is time-consuming and labor-intensive, which can reduce the overall welding progress and make it inconvenient to use the welding robotic arm. Utility Model Content

[0005] The purpose of this application is to address the problem that when a mobile trolley cannot reach the designated location, workers need to loosen multiple bolts to disassemble the welding robotic arm, which is time-consuming and labor-intensive, thus reducing the overall welding progress and making it inconvenient to use the welding robotic arm. This application provides a connecting device for a mobile welding robotic arm.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A connecting device for a movable welding robotic arm includes a plate, an electromagnetic suction device fixed on the plate, casters installed at the four corners of the lower end of the plate, a handle fixed at one end of the plate, a movable robotic arm mounted on the electromagnetic suction device, a welding head mounted at the end of the movable robotic arm away from the electromagnetic suction device, and a limiting mechanism between the electromagnetic suction device and the movable robotic arm.

[0008] By adopting the above technical solution, the electromagnetic suction device and the limiting mechanism facilitate the rapid disassembly of the mobile robotic arm, reduce the impact on the welding progress, facilitate the use of the welding robot, reduce the movement of the mobile robotic arm during welding, and enable the operator to drive the mobile robotic arm to the appropriate position for welding.

[0009] Furthermore, the limiting mechanism includes a controller fixed to one side of the plate, a fixed plate fixed to the lower end of the moving robotic arm by bolts, the fixed plate being an iron plate, the fixed plate contacting the upper end of the electromagnetic suction device, the controller being electrically connected to the electromagnetic suction device, and a limiting component being provided between the fixed plate and the electromagnetic suction device.

[0010] By adopting the above technical solution, the electromagnetic suction device is activated to magnetically fix the fixed plate, which facilitates the installation and disassembly of the mobile robotic arm.

[0011] Furthermore, the limiting component includes multiple support plates fixed on the plate body, the support plates being located within the electromagnetic attraction device, a fixing plate being provided on one side of the support plate, a limiting plate being fixed on the fixing plate, and a limiting element being provided between the fixing plate and the electromagnetic attraction device.

[0012] By adopting the above technical solution, the movement of the limiting plate drives the movement of the fixed plate, and the limiting components facilitate the installation and disassembly of the mobile robotic arm.

[0013] Furthermore, the limiting component includes a limiting post slidably disposed on the support plate, the limiting post passing through the support plate and fixedly connected to the fixing plate, a spring being sleeved on the limiting post, a limiting block being fixed to one end of the limiting post, and the end of the spring being fixedly connected to both the limiting block and the support plate.

[0014] By adopting the above technical solution, the fixed plate abuts against multiple limiting plates, causing the limiting column to move on the support plate, which causes the spring to extend and retract, and the fixed plate to contact the fixed plate, so that the fixed plate abuts against the support plate, which facilitates the improvement of the restriction on the moving robotic arm.

[0015] Furthermore, a pad is provided between the fixing plate and the support plate, and the pad is a rubber shock absorber.

[0016] By adopting the above technical solution, the fixed plate abuts against the pad, which is a rubber shock-absorbing plate, which can absorb the vibration during welding of the mobile robotic arm, reduce vibration, and facilitate welding.

[0017] Furthermore, the fixing plate is in contact with the fixing disk, and the contact surfaces of the fixing plate and the fixing disk are both rough metal surfaces.

[0018] By adopting the above technical solution, the contact surfaces of the fixing plate and the fixing disk are both rough metal surfaces, which facilitates increasing the friction between the fixing disk and the fixing plate, increasing the restraining force, and reducing the movement of the fixing disk.

[0019] Furthermore, the limiting plate is inclined, and the ends of the limiting plate are arc-shaped.

[0020] By adopting the above technical solution, the mobile robotic arm is restricted and positioned by an inclined limiting plate. The end of the limiting plate is arc-shaped, which facilitates the contact of the fixed plate with the limiting plate and the fixation and restriction of the mobile robotic arm.

[0021] Furthermore, a support column is fixed on the plate, the support column is located inside the electromagnetic attraction device, and a fixing hole is opened on the support column corresponding to the position of the fixing plate, the support column is located inside the fixing hole.

[0022] By adopting the above technical solution, the support column enters the fixing hole to restrict the fixing plate, which facilitates the fixing of the mobile robotic arm and reduces the movement of the mobile robotic arm during welding.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. During welding, the operator controls the electromagnetic suction device to start or stop via a controller, facilitating the fixing and disassembly of the mobile robotic arm. When disassembling, the electromagnetic suction device is turned off, and the mobile robotic arm is pulled out, causing the fixed plate to move as well, allowing the robotic arm to be moved to a suitable position for welding. When fixing the mobile robotic arm, it is pulled above the electromagnetic suction device, causing the robotic arm to move the fixed plate, which then contacts multiple limiting plates, causing the limiting plates to move. This movement of the limiting plates, in turn, moves the fixed plate, causing the limiting posts to move on the support plate, resulting in spring extension and contraction. The fixed plate then contacts the fixed plate, restricting its movement and reducing its movement. The electromagnetic suction device is then activated to fix the mobile robotic arm, facilitating welding. The electromagnetic suction device and limiting mechanism facilitate rapid disassembly of the mobile robotic arm, minimizing the impact on welding progress and simplifying the use of the welding robot by reducing the movement of the robotic arm during welding.

[0025] 2. When it is necessary to disassemble the mobile robotic arm, the mobile robotic arm is restricted and positioned by the inclined limiting plate. The end of the limiting plate is arc-shaped, which makes it easy for the fixed plate to abut against the limiting plate, thus facilitating the fixation and restriction of the mobile robotic arm. When the mobile robotic arm moves, the support column enters the fixing hole to restrict the fixed plate, which facilitates the fixation and restriction of the mobile robotic arm and reduces the movement of the mobile robotic arm during welding.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a connection device for a movable welding robotic arm.

[0034] Reference Figure 1 and Figure 2 A connecting device for a movable welding robotic arm includes a plate 1, an electromagnetic suction device 2 fixed on the plate 1, casters 3 installed at the four corners of the lower end of the plate 1, a handle 4 fixed at one end of the plate 1, a movable robotic arm 5 mounted on the electromagnetic suction device 2, a welding head 6 mounted at the end of the movable robotic arm 5 away from the electromagnetic suction device 2, and a limiting mechanism between the electromagnetic suction device 2 and the movable robotic arm 5.

[0035] During welding, the worker pushes handle 4 to move plate 1 to the appropriate position, and then starts the moving robotic arm 5 and welding head 6, so that the moving robotic arm 5 moves the welding head 6 to flexibly weld the required position. When plate 1 cannot reach the designated position, the electromagnetic suction device 2 and the limiting mechanism facilitate the quick disassembly of the moving robotic arm 5, reduce the impact on the welding progress, facilitate the use of the welding robot, reduce the movement of the moving robotic arm 5 during welding, and enable the worker to move the moving robotic arm 5 to the appropriate position for welding.

[0036] Reference Figure 3 and Figure 4The limiting mechanism includes a controller 8 fixed to one side of the plate 1. A fixed plate 7, made of iron, is bolted to the lower end of the movable robotic arm 5 and contacts the upper end of the electromagnetic attraction device 2. The controller 8 is electrically connected to the electromagnetic attraction device 2. A limiting component is provided between the fixed plate 7 and the electromagnetic attraction device 2. The limiting component includes multiple support plates 17 fixed to the plate 1, located within the electromagnetic attraction device 2. A fixed plate 9 is provided on one side of the support plate 17, and a limiting plate 10 is fixed to the fixed plate 9. A limiting element is provided between the fixed plate 9 and the electromagnetic attraction device 2. The limiting element includes a limiting post 11 slidably mounted on the support plate 17. The limiting post 11 passes through the support plate 17 and is fixedly connected to the fixed plate 9. A spring 12 is sleeved on the limiting post 11, and a limiting block 13 is fixed to one end of the limiting post 11. The end of the spring 12 is fixedly connected to both the limiting block 13 and the support plate 17. A pad 14, made of rubber, is provided between the fixed plate 9 and the support plate 17. The fixing plate 9 is in contact with the fixing disk 7, and the contact surfaces of the fixing plate 9 and the fixing disk 7 are both rough metal surfaces.

[0037] During welding, the operator controls the electromagnetic suction device 2 to start or stop via controller 8, facilitating the fixing and disassembly of the mobile robotic arm 5. When disassembling, the electromagnetic suction device 2 is turned off, and the mobile robotic arm 5 is pulled out, causing the fixed plate 7 to move as well, allowing the mobile robotic arm 5 to be moved to a suitable position for welding. When fixing the mobile robotic arm 5, it is pulled above the electromagnetic suction device 2, causing the mobile robotic arm 5 to move the fixed plate 7, which then contacts multiple limiting plates 10, causing the limiting plates 10 to move. The movement of the limiting plates 10 moves the fixed plate 9, causing the limiting post 11 to move on the support plate 17, causing the spring 12 to extend and retract, bringing the fixed plate 7 into contact with the fixed plate 9. The fixed plate 9 abuts against the support plate 17 and the pad 14. The pad 14 is a rubber shock absorber, which is convenient for absorbing the vibration of the mobile robotic arm 5 during welding, reducing vibration, and facilitating welding. It restricts the fixed plate 7. The contact surfaces of the fixed plate 9 and the fixed plate 7 are both rough metal surfaces, which can increase the friction between the fixed plate 7 and the fixed plate 9, increase the restrictive force, and reduce the movement of the fixed plate 7. The electromagnetic suction device 2 is activated to fix the mobile robotic arm 5, which is convenient for welding. Through the electromagnetic suction device 2 and the restrictive mechanism, the mobile robotic arm 5 can be quickly disassembled, reducing the impact on the welding progress, facilitating the use of the welding robot, and reducing the movement of the mobile robotic arm 5 during welding.

[0038] Reference Figure 3 and Figure 4 The limiting plate 10 is inclined and the end of the limiting plate 10 is arc-shaped. A support column 15 is fixed on the plate 1. The support column 15 is located inside the electromagnetic suction device 2. The support column 15 has a fixing hole 16 at the position corresponding to the fixing plate 7. The support column 15 is located inside the fixing hole 16.

[0039] During welding, when it is necessary to disassemble the mobile robotic arm 5, the inclined limiting plate 10 is used to restrict and position the mobile robotic arm 5. The end of the limiting plate 10 is arc-shaped, which makes it easy for the fixed plate 7 to abut against the limiting plate 10, thus facilitating the fixation and restriction of the mobile robotic arm 5. When the mobile robotic arm 5 moves, the support column 15 enters the fixing hole 16 to restrict the fixed plate 7, which facilitates the fixation of the mobile robotic arm 5 and reduces the movement of the mobile robotic arm 5 during welding.

[0040] The implementation principle of the connecting device of the movable welding robotic arm 5 in this embodiment is as follows: During welding, the worker pushes the handle 4 to move the plate 1 to a suitable position, and then starts the movable robotic arm 5 and the welding head 6, so that the movable robotic arm 5 drives the welding head 6 to move and flexibly weld the required welding position.

[0041] During welding, the operator controls the electromagnetic suction device 2 to start or stop via controller 8, facilitating the fixing and disassembly of the mobile robotic arm 5. When disassembling, the electromagnetic suction device 2 is turned off, and the mobile robotic arm 5 is pulled out, causing the fixed plate 7 to move as well, allowing the mobile robotic arm 5 to be moved to a suitable position for welding. When fixing the mobile robotic arm 5, it is pulled above the electromagnetic suction device 2, causing the mobile robotic arm 5 to move the fixed plate 7, which then contacts multiple limiting plates 10, causing the limiting plates 10 to move. The movement of the limiting plates 10 then moves the fixed plate 9, causing the limiting post 11 to move. The movement on the support plate 17 causes the spring 12 to extend and retract, and the fixed plate 7 contacts the fixed plate 9, causing the fixed plate 9 to abut against the support plate 17 and the fixed plate 9 to abut against the pad 14. The pad 14 is a rubber shock absorber, which is convenient for absorbing the vibration during the welding of the mobile robotic arm 5, reducing vibration, facilitating welding, and restricting the fixed plate 7. The contact surfaces of the fixed plate 9 and the fixed plate 7 are both rough metal surfaces, which is convenient for increasing the friction between the fixed plate 7 and the fixed plate 9, increasing the restrictive force, reducing the movement of the fixed plate 7, and activating the electromagnetic suction device 2 to fix the mobile robotic arm 5, which is convenient for the welding of the mobile robotic arm 5.

[0042] When it is necessary to disassemble the mobile robotic arm 5, the mobile robotic arm 5 is restricted and positioned by the inclined limiting plate 10. The end of the limiting plate 10 is arc-shaped, which makes it easy for the fixed plate 7 to abut against the limiting plate 10, thus facilitating the fixation and restriction of the mobile robotic arm 5. When the mobile robotic arm 5 moves, the support column 15 enters the fixing hole 16 to restrict the fixed plate 7, thus facilitating the fixation and restriction of the mobile robotic arm 5.
