Description

Technical Field

[0001] The utility model relates to the technical field of equipment manufacturing, and in particular to a single-machine double-station welding robot automation workstation. Background Art

[0002] Manual welding is a common method in traditional welding production. However, manual welding presents numerous challenges. First, the quality stability of manual welding is poor, significantly affected by factors such as the welder's skill level, working state, and experience. Even experienced welders struggle to maintain consistent weld quality over extended periods of time, and defects such as uneven welds, porosity, and slag inclusions are common. Second, manual welding is inefficient, requiring welders to spend considerable time welding and adjusting the workpiece, and requiring frequent breaks to relieve fatigue. Furthermore, manual welding is labor-intensive, requiring welders to hold welding tools for extended periods in a harsh welding environment, where they are susceptible to the hazards of arc light, high temperatures, hazardous gases, and dust, which can negatively impact their health. While single-station welding equipment has improved the automation level of welding to a certain extent, it still has some limitations. Single-station equipment can only weld one workpiece at a time. After welding one workpiece, operations such as unloading and reloading are required before welding the next workpiece can begin. This results in long idle times and relatively low production efficiency. Moreover, single-station equipment often requires multiple clamping and adjustments for some complex-shaped workpieces or workpieces that require multi-sided welding, which is cumbersome to operate and increases production cycle and cost. For this reason, we propose a single-machine dual-station welding robot automated workstation. Utility Model Content

[0014] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0015] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example

[0017] Please refer to the drawings in the specification. In the embodiment of the present invention, a single-machine double-station welding robot automated workstation includes two welding platforms 1, and a positioner 2 is respectively provided at both ends of the two welding platforms 1; the two positioners 2 are respectively provided with connecting parts 3 at opposite positions, and a workpiece platform 4 is installed between the two connecting parts 3 by bolts; a walking rail 5 parallel to each other is provided between the two welding platforms 1; a walking platform 6 is connected to the walking rail 5, and the two form a sliding guide fit; a base 7 is provided on the walking platform 6; a welding robot 8 is installed on the base 7; the welding arm of the welding robot 8 is set toward one side of the welding platform 1.

[0018] Furthermore, a welding wire barrel 10 is provided on the walking platform 6 on one side of the welding robot 8 .

[0019] Furthermore, the axis of the walking rail 5 and the axis of the welding platform 1 are arranged parallel to each other.

[0020] Furthermore, the walking rail 5 is connected to the walking platform 6 through a gear rack drive mechanism, and linear guide rails are provided on both sides of the walking rail 5, and the walking platform 6 and the linear guide rails form a sliding guide fit.

[0021] Furthermore, fence guard plates 9 are provided on the outer sides of the two welding platforms 1 .

[0022] Furthermore, a control cabinet 11 is provided near the positioner 2 and on one side of the fence arc plate. The control cabinet 11 is provided with a control switch for controlling the total power supply of the workpiece automatic welding system.

[0023] Usage process:

[0024] During use, the workpiece to be welded is mounted on the workpiece platform 4 via a fixture and connected to the positioner 2 via a connector 3. The positioner 2 rotates and tilts the workpiece according to a preset program or operator instructions. For example, when welding the annular seam of a cylindrical workpiece, the positioner 2 can rotate the workpiece at a constant speed so that the welding robot 8 can continuously weld along the weld seam. This positioning function enables the welding robot 8 to operate at the optimal welding position and angle, greatly improving the quality and efficiency of welding. The walking rail 5 drives the walking platform 6 to move via a gear rack drive mechanism. When switching between different welding stations, the control system issues a command, driving the motor to rotate the gear, which engages with the rack on the walking rail 5, allowing the walking platform 6 to move smoothly along the rail to the designated welding platform 1 position. The linear guides on both sides of the walking rail 5 form a sliding guide with the walking platform 6, ensuring the straightness and stability of the walking platform 6 during movement. The welding robot 8 is mounted on the base 7 of the walking platform 6 and reaches the corresponding welding station as the walking platform 6 moves. The welding arm of welding robot 8 welds the workpiece according to the preset welding path and process parameters. During the welding process, welding robot 8 uses its own joint motion and precise control of the control system to adjust the position of the welding gun tip, change its posture, and control the welding speed. Control cabinet 11, serving as the control center for the entire workstation, is responsible for centralized control and coordination of equipment such as welding robot 8, positioner 2, and travel rail 5. The control system in control cabinet 11 uses programming to control the motion of each device and set process parameters. For example, the operator can set parameters such as welding current, voltage, welding speed, and the rotation speed and angle of positioner 2 on the human-machine interface of control cabinet 11.

[0025] In the above process, the device is set up and a single-robot dual-station welding method is adopted, so that while one workpiece is being welded, the operator can load and unload and prepare the workpiece at another station, which greatly reduces the idle time of the equipment and improves the utilization rate of the equipment. Compared with single-station welding equipment, production efficiency can be significantly improved. The use of automated workstations reduces the dependence on skilled welding workers and reduces labor costs. By moving the walking platform and the positioner, all-round welding can be easily achieved without readjusting the equipment layout or replacing the equipment, which improves production efficiency and flexibility. The present application has a simple structure, strong practicality, and simple operation, which is worth promoting.
