Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a dual-robot step welding device. Background Technology

[0002] For welding plastic fuel tanks, the conventional method involves simultaneously mounting a welding head and a hot die head on a multi-axis robot. The hot die head preheats the area to be welded, and then the welding head, holding the workpiece, adheres it to the welding position. Although this is automated welding, the hot die and welding are performed sequentially, resulting in low welding efficiency.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dual-robot step-by-step welding device that can perform welding and hot mold operation simultaneously, thereby improving welding efficiency.

[0005] The technical solution of this utility model is as follows: A dual-robot step-by-step welding device is provided, comprising: a first multi-axis robot, a second multi-axis robot, a gripping welding section, and a hot mold assembly; the gripping welding section includes: a first telescopic cylinder connected to the front end of the first multi-axis robot, a welding rotating section connected to the output end of the first telescopic cylinder, and a pneumatic gripper connected to the welding rotating section; the hot mold assembly includes: a second telescopic cylinder connected to the front end of the second multi-axis robot, and a heating element connected to the output end of the second telescopic cylinder; the heating element is used to heat the welding section, and the pneumatic gripper is used to grip the workpiece and place it on the heated welding section for welding. The first telescopic cylinder is used to realize the up-and-down movement of the pneumatic gripper, and the welding rotating section is used to realize the rotation of the pneumatic gripper, thereby enabling better gripping of the workpiece, and the pneumatic gripper is used to grip the workpiece and place it at the position to be welded. The second telescopic cylinder is used to realize the up-and-down movement of the heating element, and the heating element is used to heat the position to be welded, so that the workpiece gripped by the pneumatic gripper can be placed at the welding position for welding.

[0006] In application, the heating element first heats the area to be welded, and then the pneumatic gripper can place the welding rod on the heated area for welding. While welding, the heating element can heat the next area to be welded. That is, while the first multi-axis robot is performing welding, the second multi-axis robot can heat the next area to be welded. After the first multi-axis robot finishes one welding operation, it can directly perform the welding operation on the next area to be welded without waiting, which can greatly improve welding efficiency.

[0007] Furthermore, the gripping welding unit further includes a pneumatic pressing unit; the pneumatic pressing unit includes a pressing cylinder mounted on one side of the pneumatic gripper, and a pressing member connected to the output end of the pressing cylinder; one end of the pressing member extends between the two grippers of the pneumatic gripper. Under the action of the pressing cylinder, the pressing member can apply pressure to the weldment, thereby obtaining better welding quality.

[0008] Furthermore, the gripping welding unit also includes: a first rotating frame mounted on the front end of the first multi-axis robot, and a plurality of first telescopic cylinders of the gripping welding unit connected to the front end of the first multi-axis robot through the first rotating frame. The plurality of first telescopic cylinders are evenly distributed on the first rotating frame. Multiple gripping welding units can grip multiple workpieces simultaneously, eliminating the need to retrieve them from the workpiece storage point for each welding operation, thus improving efficiency.

[0009] Furthermore, the thermal molding assembly also includes: a second rotating frame mounted on the front end of the second multi-axis robot, and a plurality of second telescopic cylinders of the thermal molding assembly connected to the front end of the second multi-axis robot via the second rotating frame. The plurality of second telescopic cylinders are evenly distributed on the second rotating frame. Multiple thermal molding assemblies can sequentially heat the areas requiring welding, avoiding prolonged heating operations for a single thermal molding assembly and extending the service life of the thermal molding assembly.

[0010] Furthermore, the thermal mold assembly also includes an extension plate, through which the output end of the second telescopic cylinder is connected to the heating element. The extension plate is used for better mounting of the heating element.

[0011] By adopting the above solution, this utility model provides a dual-robot step-by-step welding device. In application, the heating element first heats the position to be welded, and then the pneumatic gripper can place the welding point on the heated position for welding. While welding, the heating element can heat the next position to be welded. That is, while the first multi-axis robot is performing welding, the second multi-axis robot can heat the next position to be welded. After the first multi-axis robot completes one welding operation, it can directly perform the welding operation on the next position to be welded without waiting, thereby greatly improving welding efficiency.
