[0003] Currently, automotive body-in-white welding production lines that rely entirely on manual labor involve manual operation of equipment for tasks such as switching between production lines, unloading parts, stud welding, welding quality inspection, and marking. This means manual loading of parts, manual operation of welding torches, and manual unloading after welding. Different products require different equipment, necessitating manual switching between different devices for each product. This production method is not only labor-intensive and difficult, but also has relatively low production efficiency and product qualification rates. Furthermore, the large number of production equipment results in a large footprint and high investment costs, increasing production costs and resource waste. The frequent switching between different production equipment to adapt to the production needs of different products makes it difficult to meet the requirements of modern production lines for flexibility, automation, high efficiency, and high qualification rates.

[0076] In specific use of this embodiment, firstly, the worker clamps the workpiece 100 onto the clamping and fixing device 200. The first positioning block 209 and the first protrusion 210 on the clamping and fixing device 200 cooperate to position and clamp the workpiece. After the first sensor 211 on the clamping and fixing device 200 senses that the workpiece 100 is in place, the welding robot 302 on the robotic welding device 300, carrying the welding clamp 303, performs welding according to the taught trajectory. After welding is completed, the welding robot 302 on the robotic welding device 300 replaces the welding robot 302 with a handling gripper to pick up the workpiece 100 from the first protrusion and transport it to the first buffer device 500. At this time, the first sensor 211 no longer senses the workpiece 100 and issues a signal indicator light. When 1409 is turned off, the worker can proceed with loading the workpiece. The welding robot 302 on the robotic welding device 300 switches to welding clamp 303 to continue welding workpiece 100. Next, workpiece 100 is placed on the first buffer device 500 and positioned by the third positioning block 503. When the third sensor 504 senses workpiece 100, it sends a signal, and the first handling robot 401 on the gripper handling device 400, carrying gripper frame 405, second positioning block 406, second protrusion 407, and second sensor 408, grasps workpiece 100 from the first buffer device 500. The second positioning block 406 positions workpiece 100, and the second protrusion 407 clamps and restricts workpiece 100. After sensor 408 detects workpiece 100, it sends a signal. The gripper transport device 400 then transports the workpiece between the first welding robot 600 and the second welding robot 700. At this point, the third sensor 504 cannot detect workpiece 100, and the robot welding device 300 can continue to place workpiece 100 on the first buffer device 500, reducing robot waiting time and increasing production cycle time. Then, the first welding robot 600 and the second welding robot 700 perform aerial repair welding on workpiece 100. After the repair welding is completed, the gripper transport device 400 transports the workpiece to the stud welding device 800, where the stud welding gun 801 and stud welding support arm 802 cooperate to perform stud welding on workpiece 100. After the stud welding is completed, the gripper transport device 400... The transport device 400 carries the workpiece to the second buffer device 900. The fourth positioning block 903 positions the workpiece 100, and the fourth sensor 904 senses the workpiece 100 and gives a signal. The gripper transport device 400 then disengages from the workpiece 100 and continues to return to transport the buffered workpiece 100 on the first buffer device 500 to the vicinity of the first welding robot 600 and the second welding robot 700. Subsequently, it is transported to the stud welding device 800 for stud welding and finally placed on the second buffer device 900. Due to the first buffer device 500 and the second buffer device 900, the gripper transport device 400 can achieve the goal of not waiting for the workpiece 100, which greatly improves the production cycle of the automated equipment.Then, the second transport robot 1000 picks up the workpiece 100 from the second buffer device 900 and transports it to the vision inspection device 1100. At this time, the second buffer device 900 can continue to buffer the workpiece 100. The workpiece 100 picked up by the second transport robot 1000 has its image information captured by the camera 1102 to detect its welding quality. After the detection is passed, the second transport robot 1000 transports the workpiece 100 to the laser marking device 1200, where the laser generator 1201 performs laser marking on the workpiece 100. Finally, after the marking is completed, the workpiece 100 is placed on the belt conveyor 1300. The detection grating 1302 detects the workpiece 100 and sends a signal. The second transport robot 1000 releases the workpiece 100, and the belt conveyor 1301 starts to transport the workpiece 100 to the storage tray 1304. The worker then inspects and transports it to the next workstation. At this time, the second transport robot 1000 continues to pick up and transport the workpiece 100 from the second buffer device 900.
