[0002] Solar water heater is a kind of equipment using solar energy to heat water, it converts solar energy into heat energy, thereby providing hot water, flat-plate solar water heater is one of them, its working principle is based on thermal siphon principle. When sunlight shines on the collector, the temperature of the collector rises rapidly, causing the medium (usually water or antifreeze) in the flow passage to expand and become less dense, thereby naturally rising. These heated media circulate to the water tank through the pipeline, transferring heat to the water in the water tank, causing it to heat up. And the relatively low temperature water or medium has a larger density, and returns to the bottom of the collector to continue absorbing heat and circulating heating. In rainy days or when the water temperature is insufficient, some flat-plate solar water heaters are also equipped with an electric auxiliary heating system to ensure stable supply of hot water.

[0003] Flat-plate solar water heaters generally use copper no header as a medium flow passage for heat exchange, which is usually installed in the collector.

Then, the high-frequency welding head 7 is moved upwards, so that the high-frequency welding head 7 is sleeved outside the distribution head 46 and the ceramic positioning sleeve 47. Then, the high-frequency welding machine power supply 35 and the high-frequency welding head 7 can be controlled to operate, and the high-frequency welding is performed between the header 45 and the distribution head 46. At the same time, the water chiller 8 operates to cool the high-frequency welding machine power supply 35. After the welding is completed, the cylinder 24 is retracted to drive the welding table 23 to be flat. Then, the driving motor 18 is controlled to operate in reverse to drive the rotating shaft 15 and the synchronous pulley 16 to rotate in reverse, thereby driving the synchronous belt 17 to operate in reverse, so that the slide table 20 slides in reverse and moves to the outside of the outer guardrail 1. Then, the second multi-specification adaptive positioning tool 10 can be controlled to repeat the above-mentioned actions of the first multi-specification adaptive positioning tool 9, so as to perform the welding between the header 45 mounted on the top of the second multi-specification adaptive positioning tool 10 and the distribution head 46. During the welding of the second multi-specification adaptive positioning tool 10, the staff can release the clamping and fixing of the completed header 45 by the clamp assembly 25 on the top of the first multi-specification adaptive positioning tool 9, and replace the next group of un-welded headers 45. When the welding of the header 45 on the second multi-specification adaptive positioning tool 10 is completed and the slide table 20 on the top of the second multi-specification adaptive positioning tool 10 exits from the inside of the outer guardrail 1, the driving motor 18 on the first multi-specification adaptive positioning tool 9 can be controlled to drive the slide table 20 to enter the outer guardrail 1 to perform the welding on the header 45 on the first multi-specification adaptive positioning tool 9. At this time, the header 45 on the top of the second multi-specification adaptive positioning tool 10 can be replaced. Through the alternation of the first multi-specification adaptive positioning tool 9 and the second multi-specification adaptive positioning tool 10, the welding and replacement of the header 45 are performed, so that the welding work is continuously performed. When the two groups of headers 45 are continuously welded, there is no need to wait for the replacement and re-clamping process, so as to improve the welding efficiency. At the same time, the device adopts the welding mode of the high-frequency welding machine power supply 35, the high-frequency welding head 7 and the water chiller 8 for high-frequency welding, and the automatic movement and positioning of the high-frequency welding head 7 by the AI vision camera 48 and the six-axis mechanical arm 6. Compared with the manual flame brazing mode in the prior art, the pollution is small, the safety is higher, the automation degree is higher, and the personnel training difficulty is low.
