DETAILED DESCRIPTION

[0025] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0026] In the description of the present invention, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0027] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] Traditional intelligent robot welding generally uses ground rails for mobile welding, which means that the robot can only weld in a specific working area and cannot flexibly weld according to actual needs. In addition, traditional intelligent welding robots cannot weld in a small space, which limits the scope of use of welding robots. In addition, since welding robots are prone to welding slag splashing during the welding process, the safety is low, so welding robots usually need to work separately from operators during welding, which reduces the overall work efficiency.

[0029] Specifically, in a small space, such as a ship's cubicle, the components are large in size, the grid spacing is small, the structure is relatively complex, and the space inside the cubicle is small, so welding can only be done manually in the cubicle. However, manual welding has many disadvantages for mass production. For example, the professional quality of personnel is required to be high, the welding quality depends on the skills of the welder, and the quality is difficult to control. At the same time, manual welding is inefficient and the production cost is high. In addition, the welding slag splashed during the welding process is easy to pollute the surrounding environment, which has an adverse effect on the health of the operator.

[0030] Therefore, a mobile welding workstation is now proposed to solve the above problems.

[0031] The scheme is further illustrated by the following examples:

[0032] Figure 1 It is a schematic diagram of a mobile welding workstation according to an embodiment of the utility model. Figure 2 yes Figure 1 Top view of the mobile welding workstation. Figure 3 yes Figure 1 Side view of the mobile welding workstation.

[0033] Among them, Figure 2 The left and right directions in the figure are the longitudinal directions of the mobile welding workstation. Figure 2 The up and down directions in the figure are the horizontal directions of the mobile welding workstation. Figure 2 The direction perpendicular to the paper surface is the vertical direction of the mobile welding workstation.

[0034] See also Figure 1 and Figure 2 The mobile welding workstation of this embodiment may include a vehicle body 10 , a robot arm 20 , a welding gun 31 and a welding power source 32 .

[0035] The vehicle body 10 is movable, and the vehicle body 10 may include a first mounting portion 11 and a second mounting portion 12 in the longitudinal direction, the robot arm 20 and the welding power source 32 are respectively mounted on the second mounting portion 12 and the first mounting portion 11, the welding gun 31 is mounted at the free end of the robot arm 20, so that the robot arm 20 can drive the welding gun 31 to move and perform welding, and the welding power source 32 is electrically connected to the welding gun 31 to provide electrical energy to the welding gun 31. Therefore, the vehicle body 10 can drive the robot arm 20 and the welding power source 32 to move, and the robot arm 20 can drive the welding gun 31 to move and weld, so that the welding gun 31 can automatically perform welding.

[0036] See also Figure 1 and Figure 3 The vehicle body 10 may include a running wheel set 17 and a universal wheel set 18. The running wheel set 17 is fixed to the bottom of the first mounting portion 11 and is located on a side away from the second mounting portion 12, and the universal wheel set 18 is fixed to the bottom of the second mounting portion 12 and is located on a side away from the first mounting portion 11, so that the running wheel set 17 and the universal wheel set 18 can support the vehicle body 10 and drive the vehicle body 10 to move.

[0037] In this embodiment, the vehicle body 10 may further include a locking member 181. The locking member 181 is connected to the universal wheel set 18, so that the locking member 181 can lock the universal wheel set 18 to prevent the universal wheel set 18 from rolling. When the vehicle body 10 needs to be moved, the locking member 181 is unlocked, so that the vehicle body 10 can roll, thereby enabling the vehicle body 10 to move. After the vehicle body 10 moves to the welding station, the locking member 181 locks the universal wheel set 18 to prevent the universal wheel set 18 from rolling, so that the vehicle body 10 is limited to the welding station, thereby ensuring the welding efficiency of the robot arm 20 and the welding gun 31.

[0038] See also Figure 1 and Figure 2 , both lateral ends of the first mounting portion 11 can extend outwardly beyond the second mounting portion 12, that is, in the lateral direction, the size of the second mounting portion 12 can be smaller than the size of the first mounting portion 11. At the same time, the vertical projection of the bottom of the robot arm 20 is located inside the second mounting portion 12, so that both the second mounting portion 12 and the robot arm 20 can be moved to the welding station. That is, the robot arm 20 and the second mounting portion 12 can be moved to the welding station in a narrow space, and the structure around the welding station is prevented from interfering with the vehicle body 10.

[0039] It should be noted that, due to the large size of the welding power source 32, when it is placed on the first mounting portion 11, the first mounting portion 11 needs to have a large mounting area, so that the welding power source 32 and the first mounting portion 11 cannot enter the narrow space. Therefore, the design of different lateral dimensions of the first mounting portion 11 and the second mounting portion 12 can enable the robot arm 20 located on the second mounting portion 12 to extend into the narrow space, thereby maximally moving the robot arm 20 and the second mounting portion 12 to the narrow space, and then enabling the robot arm 20 and the welding gun 31 to perform automatic welding in the narrow space.

[0040] See also Figure 1 and Figure 3 The mobile welding workstation may further include a connecting base 21 .

[0041] The connection base 21 is fixed on the second mounting portion 12. Specifically, the connection base 21 is fixed on the second mounting portion 12 by bolts. The mechanical arm 20 is detachably connected to the connection base 21 to facilitate the installation and removal of the mechanical arm 20.

[0042] It should be noted that the robot arm 20 is configured as a multi-axis robot so that the robot arm 20 has multiple degrees of freedom and the free end of the robot arm 20 has a certain flexibility, thereby driving the welding gun 31 to automatically perform welding.

[0043] In this embodiment, the robot arm 20 can be set as a six-axis robot, so that the robot arm 20 can drive the welding gun 31 to weld. Of course, in some other embodiments, the number of axes of the robot arm 20 can also be set according to actual needs to meet the needs of driving the welding gun 31 to weld.

[0044] In addition, the robot arm 20 can be controlled by software or manually taught so that the robot arm 20 and the welding gun 31 can perform automatic welding as required.

[0045] In addition, in this embodiment, the connecting base 21 can be configured as a magnetic base, so that the robotic arm 20 can be detachably connected to the connecting base 21 by magnetic attraction, thereby facilitating the installation or disassembly of the robotic arm 20.

[0046] In some other embodiments, a mounting hole may be provided on the second mounting portion 12. A connecting hole 22 is provided at the bottom of the robot arm 20, and a connecting member can be simultaneously passed through the mounting hole and the connecting hole 22, so that the robot arm 20 can be fixed on the second mounting portion 12 through the connecting member, thereby fixing the robot arm 20 on the second mounting portion 12. The connecting member may be a connecting bolt.

[0047] It should be noted that, after the robotic arm 20 is installed on the second installation portion 12 , the robotic arm 20 can move along with the vehicle body 10 , thereby facilitating the transfer of the robotic arm 20 to the welding station and reducing manpower handling.

[0048] When facing a special welding environment and the second mounting portion 12 cannot be extended into the welding station, the robot arm 20 can be disassembled from the connecting base 21 and transported to a welding station in a narrow space, so that the robot arm 20 and the welding gun 31 can work alone at the welding station, which can also improve the application range of the robot arm 20 and the welding gun 31. It should be noted that after the robot arm 20 is manually transported to the welding station, the staff can leave the station during welding, so that the robot arm 20 automatically drives the welding gun 31 to weld.

[0049] See also Figure 1 and Figure 3 The mobile welding workstation may further include a bracket 13 and a wire feeder 33 .

[0050] The bracket 13 is fixed on the first mounting portion 11, and the bracket 13 is wrapped around the outer periphery of the welding power source 32, and is spaced apart from the welding power source 32. That is, the bracket 13 and the welding power source 32 are simultaneously mounted on the first mounting portion 11, and the supporting feet of the bracket 13 are located on the peripheral side of the welding power source 32, so that the bracket 13 is wrapped around the outer periphery of the welding power source 32, thereby improving the space utilization of the first mounting portion 11 in the vertical direction.

[0051] In this embodiment, the wire feeder 33 is used to provide welding wire to the welding gun 31. The wire feeder 33 can be installed on the bracket 13 and located above the welding power source 32, so as to avoid interference of the bracket 13 and the welding power source 32 with the wire feeding.

[0052] Figure 4 yes Figure 1 Schematic diagram of a three-dimensional view of a mobile welding workstation.

[0053] See also Figure 4The mobile welding workstation may further include a gas cylinder 34, a support frame 14 and a connecting frame 15. The support frame 14 is fixed to the first mounting portion 11 and is located on the lateral side of the vehicle body 10. The connecting frame 15 is fixed to the bracket 13, and both the support frame 14 and the connecting frame 15 are located on one lateral side of the vehicle body 10, so that the bottom of the gas cylinder 34 overlaps the support frame 14, and the side wall of the gas cylinder 34 is connected to the connecting frame 15, so that the gas cylinder 34 can move with the vehicle body 10.

[0054] In this embodiment, the gas cylinder 34 can be connected to the welding gun 31 to provide shielding gas for the welding gun 31 during welding, or provide fluxing gas for the welding gun 31. Specifically, the gas cylinder 34 can be loaded with shielding gas such as carbon dioxide, or can also be loaded with gas such as acetylene and methane.

[0055] See also Figure 2 The mobile welding workstation can also include a hook 16.

[0056] Specifically, the hook 16 is fixed on the bracket 13 to receive cables connected to the outside. The cables may be power transmission cables connected to the welding power source 32 to provide power to the welding power source 32. In this embodiment, the hook 16 is provided to facilitate the storage and use of the cables, thereby facilitating the mobile welding workstation to perform welding between different welding stations.

[0057] See also Figure 1 and Figure 3 The mobile welding workstation may further include a control cabinet 35 .

[0058] The control cabinet 35 can be installed on the bracket 13 , which improves the space utilization of the vehicle body 10 and the bracket 13 .

[0059] In this embodiment, the control cabinet 35 is electrically connected to the robot arm 20 and the welding power source 32 to control the robot arm 20 and the welding power source 32 to work or stop.

[0060] It should be noted that the control cabinet 35 may be provided with a wireless communication module 351. The wireless communication module 351 may be infinitely connected to an external mobile terminal, such as a PDA, so that the control cabinet 35 can be wirelessly connected to the external mobile terminal through the wireless communication module 351, and the staff can monitor or operate the welding of the welding gun 31 through the mobile terminal.

[0061] In addition, the mobile welding workstation may further include a visual sensor 36. The visual sensor 36 is connected to the free end of the robot arm 20 to monitor the welding track of the welding gun 31 and form monitoring information. The visual sensor 36 is electrically connected to the control cabinet 35 to transmit the monitoring information to the control cabinet 35.

[0062] At the same time, the mobile welding workstation may also include an arc sensor, and the arc sensor is connected to the free end of the robot arm 20 to monitor and track the welding trajectory of the welding gun 31, thereby ensuring the quality of the weld.

[0063] In summary, the robot arm 20 and the welding power source 32 are respectively arranged on the first mounting portion 11 and the second mounting portion 12 of the vehicle body 10, so that the robot arm 20 and the welding power source 32 can be placed on a mobile welding station. In addition, the two lateral ends of the first mounting portion 11 extend outwardly beyond the second mounting portion 12, so that the second mounting portion 12 and the robot arm 20 can enter a welding station in a narrow space, thereby avoiding interference of the space with the vehicle body 10. At the same time, the robot arm 20 drives the welding gun 31 to automatically weld the parts to be welded, thereby reducing manual operation and avoiding manual welding in a narrow space.
