[0021] Reference below Figures 1 to 6 The present invention describes a robot welding production line for running wheel assemblies in an embodiment of the present invention.

[0022] The embodiment of the present application discloses a running wheel assembly robot welding production line, including: a tendon loading rack 5, a running wheel loading rack 6, a robot welding system 1, a robot handling system 3, a robot cutting system 2, and a running wheel assembly unloading rack 7.

[0023] Among them, the tendon loading rack 5 carries the tendon workpiece; the running wheel loading rack 6 carries the running wheel workpiece; the running wheel assembly consists of a running wheel workpiece and two tendon workpieces; the robot handling system 3 is provided with a handling robot 31, and the handling robot 31 is used for grabbing and transporting the running wheel workpiece and the running wheel assembly; the robot welding system 1 is provided with a first welding robot 11, a second welding robot 12, an automatic welding tool 13 and a head and tail frame positioner 14, the first welding robot 11 and the second welding robot 12 are spaced apart and arranged on one side of the automatic welding tool 13, and the first welding robot 11 and the second welding robot 12 are spaced apart and arranged on one side of the automatic welding tool 13. The welding robots 12 are used for grabbing, positioning, assembling and welding the running wheel components; the automatic welding tooling 13 is used for clamping and fixing the running wheel workpiece, and the automatic welding tooling 13 is connected with the head and tail frame positioner 14 in transmission, and the head and tail frame positioner 14 is used to rotate and adjust the position of the automatic welding tooling 13 to facilitate the positioning, assembling and welding of the workpiece; the robot cutting system 2 is provided with a cutting robot 21 and a cutting tooling 22, the cutting robot 21 is located on one side of the cutting tooling 22, the cutting tooling 22 is used for clamping and fixing the running wheel component, and the cutting robot 21 is used to cut a notch in the running wheel component.

[0024] The production process of the running wheel assembly is as follows: first, the handling robot 31 grabs the running wheel workpiece from the running wheel loading rack 6 and places it on the automatic welding fixture 13. The automatic welding fixture 13 automatically clamps the running wheel workpiece to fix it. Then, the head and tail rack positioner 14 rotates to adjust the position of the running wheel workpiece, thereby facilitating the subsequent positioning and pairing of the running tendon workpiece; secondly, the first welding robot 11 and the second welding robot 12 alternately grab the running tendon workpiece to the running wheel workpiece to complete the positioning and pairing of the running tendon workpiece. Then, the first welding robot 11 and the second welding robot 12 cooperate with the head and tail rack positioner 14 to complete the The running wheel workpiece is welded with the running wheel workpiece to construct a running wheel assembly, wherein, when the first welding robot 11 grabs, the second welding robot 12 spot welds the running wheel workpiece and the running wheel workpiece, similarly, when the second welding robot 12 grabs, the first welding robot 11 spot welds the running wheel workpiece and the running wheel workpiece; finally, the handling robot 31 grabs the running wheel assembly to the cutting tool 22, the cutting tool 22 automatically clamps the running wheel assembly, and then, the cutting robot 21 notches the running wheel assembly. After the cutting is completed, the handling robot 31 grabs the running wheel assembly to the running wheel assembly unloading rack 7 to complete the unloading of the running wheel assembly.

[0025] The present application realizes the automated production of running wheel assemblies by setting up a robot welding system 1, a robot cutting system 2 and a robot handling system 3, wherein the robot welding system 1 can realize the automation of the assembly and welding of the running wheel assemblies, the robot cutting system 2 can realize the automation of the notch cutting of the running wheel assemblies, and the robot handling system 3 can realize the automation of the loading and unloading of workpieces. The assembly and welding of the running wheel assemblies can be completed without human intervention, thereby effectively improving the production efficiency, ensuring the stability of the welding quality and improving the consistency of the products.

[0026] In some embodiments, for example Figure 2 As shown, a tendon secondary positioning platform 15 is also provided in the robot welding system 1. Two tendon secondary positioning platforms 15 are provided. The two tendon secondary positioning platforms 15 are respectively located outside the first welding robot 11 and the second welding robot 12. When the tendon workpiece is loaded, the tendon workpiece is first loaded from the tendon loading rack 6 to the tendon secondary positioning platform 15. The tendon secondary positioning platform 15 precisely positions the tendon workpiece to improve the positioning accuracy of subsequent tendon workpieces. The setting of the tendon secondary positioning platform 15 can effectively improve the positioning accuracy of the tendon workpiece, making the matching deviation between the tendon workpiece and the running wheel workpiece smaller, thereby ensuring the production consistency of the running wheel assembly.

[0027] In some embodiments, for example Figure 5 As shown, the cutting tool 22 includes a tooling platform 221, a tooling bracket 222, a clamping cylinder 223 and a flipping cylinder 224; the tooling platform 221 is flipably mounted on the tooling bracket 222 through a rotating shaft, the flipping cylinder 224 is mounted on the tooling bracket 222 and is located below the tooling platform 221, and the flipping cylinder 224 is transmission-connected to the tooling platform 221 to drive the tooling platform 221 to flip; the clamping cylinder 223 is arranged on the tooling platform 221, and the clamping cylinder 223 is used to fix the running wheel assembly on the tooling platform 221.

[0028] When the handling robot 31 loads the running wheel assembly onto the tooling platform 221, the running wheel assembly is placed vertically, and at the same time, the clamping cylinder 223 fixes the running wheel assembly. Subsequently, the flipping cylinder 224 is actuated to flip the tooling platform 221 around the rotating axis, so that the running wheel assembly changes from a vertical posture to a flat placement, which makes it convenient for the cutting robot 21 to perform notch cutting on the running wheel assembly; when the cutting is completed, the flipping cylinder 224 is actuated again to flip the tooling platform 221 back, and then the handling robot 31 grabs the cut running wheel assembly and places it on the running wheel assembly unloading rack 7 to complete the unloading.

[0029] In some embodiments, for example Figure 5 As shown, a cutting gun 211 is provided on the cutting robot 21, and the cutting robot 21 uses the cutting gun 211 to perform notch cutting on the running wheel assembly.

[0030] In some embodiments, for example Figure 4 As shown, the handling robot 31 is provided with a gripper frame 311, a first electromagnetic gripper 312 and a pneumatic gripper 313; the first electromagnetic gripper 312 and the pneumatic gripper 313 are both arranged on the gripper frame 311, and are respectively located on the upper and lower sides of the gripper frame 311; the handling robot 31 uses the first electromagnetic gripper 312 to complete the loading of the running wheel workpiece, and uses the pneumatic gripper 313 to complete the loading and unloading of the running wheel assembly.

[0031] The first electromagnetic gripper 312 can absorb the running wheel workpiece through magnetic attraction to complete the loading. This method has a fast loading speed and can effectively improve production efficiency. When the running wheel assembly is completed by welding and cutting, the overall temperature of the running wheel assembly is relatively high. At this time, the high temperature will cause the magnetic attraction force to weaken. If the first electromagnetic gripper 312 is used to grab the running wheel assembly, it will easily cause the running wheel assembly to fall off. Therefore, the pneumatic gripper 313 is used to grab the running wheel assembly to prevent the running wheel assembly from falling off.

[0032] In some embodiments, for example Figure 3 As shown, the first welding robot 11 and the second welding robot 12 are both provided with a welding gun assembly 16 and a second electromagnetic gripper 17. The second electromagnetic gripper 17 is used to complete the loading of the running tendon workpiece, and the welding gun assembly 16 is used to complete the loading and pairing of the running tendon workpiece and the welding of the running wheel assembly.

[0033] Furthermore, gun cleaning and wire cutting stations 18 are provided on the sides of the first welding robot 11 and the second welding robot 12 , and the gun cleaning and wire cutting stations 18 are used to clean the welding gun assembly 16 .

[0034] In some embodiments, for example Figure 6 As shown, the running wheel assembly robotic welding production line also includes a dust removal system 4, which includes a dust collector 41, a dust collection pipe 42 and a dust hood 43. The dust collector 41 is connected to the dust collection hood 43 through the dust collection pipe 42, and the dust collection hood 43 is arranged near the robotic welding system 1 and the robotic cutting system 2.

[0035] The setting of the dust removal system 4 can ensure the safety of the production environment, reduce the waste gas content in the production environment, reduce pollution to the environment, and protect environmental safety.

[0036] In some embodiments, for example Figure 1 As shown, two sets of the tendon loading rack 5, the running wheel loading rack 6 and the running wheel assembly unloading rack 7 are respectively provided.

[0037] When one of the two sets of tendon loading racks 5 or the two sets of running wheel loading racks 6 has no workpiece, the remaining set continues to be used for production, and at the same time, the other set of loading racks is replenished. When one of the two sets of running wheel assembly unloading racks 7 is full, the remaining set continues to be used to receive the running wheel assemblies, and at the same time, the other set of unloading racks is transported and unloaded. This alternating cycle of loading and unloading can ensure the continuous operation of the production line.

[0038] Other structures and operations of the running wheel assembly robot welding production line according to the embodiment of the present invention are known to ordinary technicians in the field and will not be described in detail here.
