Nine-axis cantilever workstation – Technical solution

by Shaanxi Jingtai Cooperation
Laser technology Co.,Ltd

This solution is applicable to the intelligent welding of typical workpieces in the industry.
Unified description of weld analysis:
(1) Red markings indicate weldability, and yellow markings indicate non – weldability.

(2) Welds at typical parts are marked. Welds of the same type but at different parts may have their markings omitted. Other unmarked parts are not to be welded.

(3) The height (H) and spacing (W) of the part plates must meet the requirements in the chart. If they exceed the range, the standard welding torch cannot be used for welding.

4) The included angle (tilt angle) α of the part plate should not be less than 70 degrees. If it exceeds this angle, the welding quality when the welding torch descends will be affected.

Process Description:
1. Positioning and spot welding of workpieces is manually performed at Workstation 1. Then, the robot moves to Workstation 1 and conducts overall identification and reverse modeling of the workpiece through the global camera (multiple workpieces can be identified simultaneously).

2. After the system obtains the data, it generates a precise positioning program to drive the robot’s end – effector vision to conduct precise scanning in a node – based mode.

3. Once the scanning is completed, the system generates a welding program, and the robot executes the welding.

4. While the robot is working as described above, manual assembly and spot – welding are carried out at Workstation 2.

After the robot finishes welding the workpiece at Workstation 1, it moves to Workstation 2 to perform the above – mentioned welding tasks.

5. Workers transfer the welded finished products at Workstation 1 to the subsequent workstations.

Operating System OS

The system is completely independently developed byus. Its main function is to deeply integrate the welding process. It accurately locates the component welds through the vision system. Based on the obtained weld coordinate information, it automatically generates welding programs by integrating the welding expert database.

The software is deployed on the PC system. The PC system can be placed anywhere, and remote control of the equipment for welding can be achieved through the TCP/IP protocol.

Welding Torch Cleaning Station – TERMA

This cleaning station is designed to remove spatters that adhere and clog the gas shield sleeve of the welding torch during the automatic welding operation of the welding robot. By doing so, it ensures the long – term unobstructed flow of gas, effectively blocks air from entering the welding area, and improves the quality of the weld seam. It also cleans the dust generated by welding fumes on the contact tip and the gas outlet holes on the connecting pipe. Additionally, it sprays torch – cleaning agent onto the gas shield sleeve to reduce the tenacious adhesion of welding slag to the nozzle and the contact tip, thereby increasing their durability.

This significantly reduces the workload of operators. It prevents the situation where untimely manual cleaning affects the welding quality. Moreover, it avoids the wear of the insulating cylinder threads between the gas shield sleeve and the body connecting pipe caused by repeated disassembly and assembly during manual cleaning, thus extending the service life, reducing costs.

It also prevents the gas shield sleeve from being installed obliquely due to thread wear, which could lead to gas deflection and ultimately cause the failure of gas protection.
