The bottom of the mounting plate 6 is provided with a first monitoring camera 7, which is responsible for real-time monitoring of the state of the welding point during the welding process, such as problems like misalignment and non-welding of the welding point, and transmits the monitored image information to the controller 3 for immediate correction of welding defects. The bottom of the mounting plate 6 is provided with a temperature sensor 8, which is close to the welding head 9 and is used to accurately measure the temperature change of the welding point to prevent welding quality problems caused by overheating or overcooling. The temperature data is transmitted to the controller 3 in real time for temperature adjustment and quality control. The bottom of the mounting plate 6 is provided with a welding head 9, which connects various parts of the PCB tool together by means of electric current or heat energy. The surface of the workbench 1 is provided with a second electric slide rail 16. The surface of the second electric slide rail 16 is provided with a second electric slider 17, which is used to drive the movement of the tooling fixture 18 in the horizontal direction to adapt to the welding requirements of PCB tools of different sizes and shapes. The surface of the second electric slider 17 is provided with a tooling fixture 18, which fixes the PCB tool to be welded to ensure the stable position of the tool during the welding process and improve the welding accuracy and reliability.

[0027] The surface of the workbench 1 is provided with a magnetic attraction plate 15. The bottom of the placement plate 10 is provided with a placement groove. The shape and position of the magnetic attraction plate 15 correspond to the placement groove. The surface of the magnetic attraction plate 15 is provided with a placement plate 10.

The protective cover 4 is made of transparent material to facilitate personnel observation and avoid accidents in the visual blind area. It adopts a socketing and sliding structure and realizes the adjustment of height and position through the electric push rod 12. Adjacent protective covers 4 are socketed with each other. Adjacent protective covers 4 are slidably connected through a guide block 13 and an electric push rod 12. The surface of the protective cover 4 is provided with a guide groove 11. The surface of the guide groove 11 is provided with an electric push rod 12. The end of the electric push rod 12 is provided with a guide block 13.

Through the sliding of the electric push rod 12 and the guide block 13 in the guide groove 11, it is adjusted to a suitable height. The controller 3 receives the start signal and activates the entire welding system. The moving component 5 starts to work. The first electric slide rail 501 drives the first electric slider 502 to move linearly to the initial welding position. The air cylinder 503 performs fine adjustment in the vertical direction to ensure that the welding head 9 is accurately aligned with the welding point. The first monitoring camera 7 is used to monitor the defects in the welding process in real time, such as the misalignment of the welding point, non-welding and other problems, and transmits the image information to the controller 3. The controller 3 immediately adjusts the welding parameters or position according to the feedback to correct the welding defects. The temperature sensor 8 is used to accurately monitor the temperature change of the welding point to prevent welding quality problems caused by overheating or overcooling. The temperature data is transmitted to the controller 3 in real time for temperature adjustment and quality control.

[0030] On the premise of meeting the above structure, sensors can be installed on the top surface of the outermost protective cover 4 to accurately track the movement trajectory of the welding head 9 in real time through a vision sensor or an infrared sensor. Once the position of the welding head 9 changes, the vision sensor or the infrared sensor will immediately capture this change and quickly feedback the signal to the controller 3. The controller 3 then analyzes the data and automatically adjusts the position of the protective cover 4 by controlling the electric push rod 12 to ensure that it always closely follows the movement of the welding head 9 and provides uninterrupted all-round protection for the welding area. This intelligent automatic adjustment mechanism greatly improves the safety factor of the welding operation and prevents potential damage to the operator or equipment caused by splashes.
