[0002] On automated production lines, robots serve as key welding execution mechanisms, typically connected to welding clamps or grippers to perform various tasks such as welding and handling.
[0003] Since the switching methods between robots are mostly limited to switching between welding guns or grippers, in actual production scenarios, if an automated production line needs to simultaneously perform welding and handling functions, it often requires two robots, one connected to the welding gun and the other to the gripper, to perform the corresponding tasks. However, the deployment of two robots must reserve sufficient floor space, which greatly limits the application scenarios of automated production lines when the production space is insufficient.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0038] This application provides a welding mechanism; please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of the welding mechanism provided in an embodiment of this application.
[0039] This application provides a welding mechanism, including a welding clamp 1, an adapter assembly 2, and a gripper 3. Please refer to... Figure 2 As shown, the welding clamp 1 includes a first body 11 and a first mounting assembly 12. The first body 11 is connected to the first mounting assembly 12, and the first body 11 is used to connect to the robot. Please refer to... Figure 6 and Figure 7 As shown, the adapter assembly 2 includes a first adapter plate 21 and a second adapter plate 22 that are movably connected. The first adapter plate 21 is connected to the first mounting assembly 12. The gripper 3 includes a second body 31 and a second mounting assembly 32 connected to the second body 31. The second mounting assembly 32 is connected to the second adapter plate 22. The welding clamp 1, the adapter assembly 2 and the gripper 3 are electrically connected to the robot's control module.
[0040] Specifically, the welding mechanism provided in this embodiment integrates the welding clamp 1 and the gripper 3 via a transfer component 2, achieving integrated welding and handling functions. The first transfer plate 21 and the second transfer plate 22 in the transfer component 2 are movably connected, meaning they can rotate relative to each other, allowing the welding clamp 1 and the gripper 3 to quickly switch working states. After completing the welding task, the robot drives the transfer component 2 to adjust the direction of the welding clamp 1 and the gripper 3 via a control module command, immediately switching to handling mode. Compared to traditional multi-robot collaboration, the welding mechanism provided in this embodiment eliminates the need for complex coordination processes, effectively avoiding time losses during the switching of the welding clamp 1 and the gripper 3, and improving the overall production efficiency of the welding mechanism.
[0041] In other words, compared to using one robot connected to welding gun 1 to perform welding tasks and another robot connected to gripper 3 to perform handling tasks, this application only requires one robot. Under the scheduling of the control module, the working modes of welding gun 1 and gripper 3 can be switched via the transfer component 2. The sequence of movements, force, and switching timing of welding gun 1 and gripper 3 can be precisely controlled to complete multiple tasks such as welding, gripping, and handling. This reduces the dependence on the number of robots and avoids the large area required for deploying two robots simultaneously. Especially in narrow workshops or compact automated production lines, the welding mechanism can be flexibly installed, improving space utilization and optimizing the layout of automated production lines.
[0042] Please see Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the welding clamp 1 in the welding mechanism provided in the exemplary embodiment of this disclosure; Figure 3 This is a schematic diagram of the structure of the first mounting component 12 in the welding mechanism provided in an exemplary embodiment of this disclosure; in some embodiments, the first mounting component 12 includes a first mounting plate 121 and a first connecting plate 122, the first mounting plate 121 is connected to the first body 11; the first connecting plate 122 is disposed on the side of the first mounting plate 121 away from the first body 11, and the first adapter plate 21 is connected to the side of the first connecting plate 122 away from the first mounting plate 121.
[0043] Specifically, in this embodiment, the first mounting plate 121 is tightly connected to the first body 11, thereby using the first mounting plate 121 as a basic load-bearing component to evenly distribute the force transmitted by the adapter 2 and the gripper 3, preventing the first body 11 from deforming due to uneven force. Based on this, the first connecting plate 122 is disposed on the other side of the first mounting plate 121, forming a stable mounting surface for the adapter 2. The three layers—the first body 11, the first mounting plate 121, and the first connecting plate 122—are connected by surface contact, thereby increasing the contact area, effectively reducing vibration transmission, ensuring the stability of the welding clamp 1 during welding operations, and preventing the adapter 2 and gripper 3 from loosening during switching, ensuring the safe and reliable operation of the welding mechanism.
[0044] To ensure the stability of the connection between the first body 11, the first mounting plate 121, and the first connecting plate 122, corresponding mounting holes can be made on the three components and they can be fixed with bolts, or other connection methods can be flexibly adjusted to adapt to welding clamps 1 with different structures, thereby enhancing the versatility and application expandability of the entire welding mechanism.
[0045] Furthermore, both the first connecting plate 122 and the first mounting plate 121 can be replaced according to the specifications or interface type of the adapter component 2, such as changing different sizes and hole layouts, so as to adapt to various models of the first adapter plate 21, realize the combination of welding clamp 1 with different grippers 3, and meet diverse production needs.
[0046] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of the first mounting plate 121 in the welding mechanism provided in an exemplary embodiment of this disclosure; in some embodiments, the first mounting plate 121 has at least one first wire through hole 1211, please refer to... Figure 3 and Figure 7 As shown, the first connecting plate 122 has at least one second wire hole 1221, and the first adapter plate 21 has at least one third wire hole 213. The first wire hole 1211, the second wire hole 1221 and the third wire hole 213 are connected.
[0047] Specifically, in this embodiment, the first wire hole 1211, the second wire hole 1221, and the third wire hole 213 are connected, providing a dedicated channel for the robot's connecting wires. This effectively organizes the direction of the connecting wires within the welding mechanism, making the internal layout of the welding mechanism more neat and orderly, thereby preventing the connecting wires from haphazardly tangling or crossing inside the welding mechanism. Secondly, the connection of the first wire hole 1211, the second wire hole 1221, and the third wire hole 213 provides physical protection for the connecting wires, preventing direct friction and compression between the connecting wires and the metal parts inside the welding mechanism, and preventing short circuits or leakage accidents caused by insulation layer damage. In addition, the orderly connecting wire layout provided by the connection of the first wire hole 1211, the second wire hole 1221, and the third wire hole 213 can reduce the interference of the connecting wires on the welding mechanism, preventing the normal operation of the welding clamp 1, the adapter component 2, or the gripper 3 from being affected by the pulling of the connecting wires.
[0048] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of the gripper 3 in the welding mechanism provided in an exemplary embodiment of this disclosure; in some embodiments, the second mounting assembly 32 includes a connecting rod 321 and a second mounting plate 322, the connecting rod 321 being connected to the second body 31; the second mounting plate 322 being connected to the connecting rod 321, and the second adapter plate 22 being connected to the side of the second mounting plate 322 away from the connecting rod 321.
[0049] Specifically, in this embodiment, the connecting rod 321 serves as a connecting bridge between the second body 31 and the second mounting plate 322, which can evenly distribute the stress generated by the gripper 3 during the gripping process, preventing the second mounting plate 322 from deforming due to uneven stress. The second mounting plate 322 provides a flat and stable mounting surface for the second adapter plate 22, increasing the connection strength between the second adapter plate 22 and the gripper 3, ensuring that the gripper 3 will not loosen or shift during transport. Furthermore, in this embodiment, the second body 31 is fixed to the connecting rod 321 and then connected to the second adapter plate 22 via the second mounting plate 322. This allows the second body 31 to be installed and disassembled as an independent module, facilitating the quick replacement of grippers 3 of different specifications (such as vacuum suction cups, clamps, etc.) according to different gripping needs, without requiring modification of the entire welding mechanism, significantly improving the adaptability of the welding mechanism to diverse production tasks.
[0050] In some embodiments, the second mounting assembly 32 further includes a reinforcing member 323 disposed on the side of the second mounting plate 322 opposite to the second adapter plate 22, and the reinforcing member 323 is connected to the connecting rod 321.
[0051] In this embodiment, the reinforcing member 323 is disposed on the side of the second mounting plate 322 opposite to the second adapter plate 22 and connected to the connecting rod 321, forming a triangular stable support structure, thereby effectively dispersing the stress generated by the second body 31 when gripping and carrying heavy objects. Simultaneously, it significantly improves the deformation resistance of the second mounting assembly 32 and greatly enhances the load-bearing capacity of the second body 31, enabling it to adapt to the handling of heavier and larger workpieces. Furthermore, during handling, the movement of the second body 31 is prone to vibration. If this vibration is directly transmitted to the adapter assembly 2 or welding clamp 1, it may affect the welding accuracy and the stability of the welding mechanism. This embodiment increases structural rigidity through the reinforcing member 323, effectively buffering and absorbing vibration energy and reducing the transmission of vibration to other components.
[0052] In some embodiments, the second mounting plate 322 has at least one fifth wire hole 3221, combined with Figure 7 As shown, the second adapter plate 22 has at least one fourth wire hole 222, and the fifth wire hole 3221 and the fourth wire hole 222 are connected. The fifth wire hole 3221 and the fourth wire hole 222 are used to pass the robot's connecting wire.
[0053] Specifically, the fifth wire hole 3221 and the fourth wire hole 222 provide dedicated channels for the connecting wires between the robot and the gripper 3, preventing the connecting wires from being randomly tangled or crossed inside the second mounting component 32. By centrally storing the connecting wires within the wire holes, the routing of the connecting wires inside the welding mechanism becomes more orderly and reduces the risk of misoperation caused by messy connecting wires. Secondly, the design of the fifth wire hole 3221 and the fourth wire hole 222 effectively isolates the connecting wires from adverse external environments, preventing the connecting wires from directly contacting high temperatures, sharp objects, or experiencing friction, and preventing short circuits, leakage, and other faults caused by damage to the insulation layer of the connecting wires. In addition, the orderly layout of the connecting wires reduces interference with the movement of the gripper 3, preventing the gripper 3 from being hindered from normal grasping and handling actions due to the pulling of the connecting wires. At the same time, the fixing effect of the wire holes on the connecting wires prevents the connecting wires from shaking or the interfaces from loosening during the operation of the welding mechanism, ensuring the stability of signal transmission between the robot's control module and the gripper 3, avoiding the impact of signal interruption or instability on the production rhythm, and ensuring efficient and continuous operation of the welding mechanism.
[0054] like Figure 6 As shown, in some embodiments, the second body 31 includes a plurality of grippers 311 connected to the connecting rod 321. The plurality of grippers 311 are spaced apart. The second mounting plate 322 has a mounting portion 3222. The second adapter plate 22 is connected to the mounting portion 3222. The mounting portion 3222 is located between two adjacent grippers 311.
[0055] In this embodiment, the mounting part 3222 is located between two adjacent grippers 311, ensuring uniform force distribution on the connection between the second adapter plate 22 and the second mounting plate 322. When the grippers 311 grip and transport the workpiece, the centrally symmetrical connection structure balances the forces in all directions, preventing the second mounting plate 322 from tilting, twisting, or deforming, thus enhancing the structural strength and stability of the second mounting assembly 32 and ensuring a reliable connection even under long-term heavy-duty operation. Secondly, the centrally located mounting part 3222 ensures uniform spatial distribution around the second mounting plate 322, providing more flexible space for the layout of other components (such as reinforcing members 323, wire holes, etc.). For example, wire holes or reinforcing ribs can be symmetrically arranged around the mounting part 3222 to further optimize the management of connecting wires and structural strength. Furthermore, the mounting part 3222, located between two adjacent grippers 311, can accommodate second adapter plates 22 of different specifications and shapes. Regardless of changes in the size or shape of the adapter plate interface, rapid installation can be achieved simply by ensuring its compatibility with the central mounting part 3222. This reduces reliance on specific adapter models and improves the versatility and expandability of the welding mechanism.
[0056] In some embodiments, the first body 11 further includes a second connecting disk 111, which is spaced apart from the first mounting component 12, and the side of the second connecting disk 111 facing away from the first body 11 is connected to the robot.
[0057] Specifically, the second connecting plate 111 is independent of the first mounting component 12 and its installation angle and position can be adjusted according to the robot's interface specifications or the installation requirements of the welding clamp 1. For example, if it is necessary to fine-tune the posture of the welding clamp 1 to adapt to the welding process during installation, this can be achieved by adjusting the mounting bolts or shims of the second connecting plate 111 without modifying the first mounting component 12. This simplifies the debugging process, improves equipment assembly efficiency, supports rapid adaptation between different robot models and the welding clamp 1, and enhances the versatility of the welding mechanism.
[0058] like Figure 7 As shown, in some embodiments, the first adapter plate 21 has a rotating shaft groove 211 on the side facing the second adapter plate 22, and the second adapter plate 22 has a rotating shaft 221 on the side facing the first adapter plate 21. The rotating shaft 221 is accommodated in the rotating shaft groove 211 and is rotatably connected to the first adapter plate 21.
[0059] Specifically, this embodiment utilizes the rotating connection between the rotating shaft groove 211 and the rotating shaft 221, enabling the welding clamp 1 and the gripper 3 to switch working modes via a simple rotational motion. After the robot control module issues a command, the first adapter plate 21 and the second adapter plate 22 can quickly rotate relative to each other, switching the welding clamp 1 or gripper 3 to the working position. Compared to traditional plug-in or disassembly switching, this significantly shortens task conversion time. Secondly, the rotating shaft 221 is housed within the rotating shaft groove 211, forming an embedded rotating connection structure that effectively limits radial displacement and prevents component collisions or misalignments caused by shaking during the switching process. Simultaneously, the tight fit between the rotating shaft 221 and the groove evenly distributes the torque during rotation, preventing excessive force at a single point and ensuring that the adapter assembly 2 maintains a stable connection even under frequent switching operations, reducing the risk of mechanical failure and extending the equipment's service life.
[0060] In some embodiments, the groove wall of the rotating shaft groove 211 is provided with a rotating track 212, and the adapter assembly 2 further includes a plurality of rotating members 23, which are accommodated in the rotating track 212 and are in contact with the groove wall and the rotating shaft 221.
[0061] Specifically, in this embodiment, the sliding friction of the first transfer plate 21 and the second transfer plate 22 is converted into rolling friction through the cooperation of the rotating track 212 and the rotating component 23, significantly reducing rotational resistance. When the welding clamp 1 and the gripper 3 switch functions, multiple rotating components 23 roll within the rotating track 212, making the transfer plate rotate more smoothly, shortening the switching time, reducing the robot drive load, and improving the overall operating efficiency of the welding mechanism; at the same time, it reduces the heat and wear generated by friction, extending the service life of the transfer assembly 2. Optionally, the rotating component 23 can be a ball bearing or a roller.
[0062] Secondly, the rotating component 23 fits tightly against the groove wall and the rotating shaft 221, forming a stable structure with multi-point support, effectively limiting the radial and axial displacement of the transfer plate during rotation. Even under high-speed rotation or frequent switching conditions, it can ensure that the first transfer plate 21 and the second transfer plate 22 maintain precise alignment, avoiding positioning deviations of the welding clamp 1 or gripper 3 caused by shaking, ensuring welding accuracy and gripping stability, and is especially suitable for automated production scenarios of precision workpieces.
[0063] In summary, the embodiments of this application integrate the welding clamp 1 and the gripper 3 through the adapter component 2. The robot only needs to connect to the first body 11 of the welding clamp 1 to achieve the integration of welding and handling functions by switching between the welding clamp 1 and the gripper 3.
