[0014] Compared with the prior art, the present invention provides a welding device for a photovoltaic power generation bracket, which has the following beneficial effects: The welding device of the photovoltaic power generation bracket is operated by the feeding component. Driven by the feeding disk, the workpiece begins to rotate at a uniform speed, so that the workpiece can be accurately transferred to the welding area according to the preset order, thereby building a set of efficient and smooth continuous feeding system, which lays a solid foundation for the subsequent seamless continuous welding operation. With the dynamic changes of the feeding disk, the interlayer and the sealing cavity components are flexibly switched and closed to form a closed space. In this closed environment, the high-temperature fume recovery component not only filters the fume generated during the welding process to minimize the pollution of the fume to the surrounding environment, but also with the synergistic effect of the workpiece preheating component, it can also preheat the workpiece before welding, so that the workpiece can reach the required welding temperature more quickly and evenly in the subsequent welding process, thereby significantly improving the welding quality and efficiency.

[0015] The welding device of the photovoltaic power generation bracket generates heat through the continuous operation of the welding head, so that the heat dissipation fin structure conducts heat outward and dissipates heat.

The hot air flow is discharged through the annular air outlet head, and then the heat flow inside the conveying hose can be further heated through the heat conduction fin structure, thereby improving the heat utilization efficiency.

[0016] The welding device of the photovoltaic power generation bracket absorbs the fume generated by welding through a high-temperature fume recovery component and performs fume filtration treatment. After filtration, the waste heat of the clean gas is used to accurately guide it out and act on the workpiece to be welded. Under the action of the workpiece preheating component, the workpiece gradually heats up and reaches a suitable initial welding temperature in advance. Secondly, the heat generated by the welding of the welding head is also conducted to the vortex tube structure through the heat conduction component. After the vortex tube structure is separated into cold and hot, the cold air flow cools the heat dissipating fin structure through the cooling head structure, and the hot air flow is discharged through the annular air outlet head. The discharged hot air flow contacts the heat-conducting fin structure with excellent thermal conductivity. The heat-conducting fin structure quickly conducts the heat of the hot air flow to the inside of the conveying hose. After the heat flow inside the conveying hose absorbs this part of the heat, the temperature further increases, realizing the full utilization of the lost heat, avoiding energy waste, and truly realizing the all-round and multi-level recycling of energy, reflecting the advanced design concept of high efficiency, energy saving and environmental protection.

[0025] Example 3: Reference Figure 2 、 Figure 5-Figure 6 and Figure 8-Figure 9 A photovoltaic bracket welding device includes a welding auxiliary mechanism 200, which includes a feeding assembly 201, a sealed cavity assembly 202 connected to the feeding assembly 201, and a plurality of partitions 203 arranged above the feeding assembly 201. The partitions 203 cooperate with the sealed cavity assembly 202 to form a closed space to ensure the subsequent preheating operation. The power generation bracket welding mechanism 100 includes a welding robot 101 and a workpiece preheating assembly 102. The hot air head structure 1021 of the workpiece preheating assembly 102 is fixedly connected to the upper ring cover 2021 of the sealed chamber assembly 202. A welding head 104 is installed at one end of the welding robot 101. A heat conduction assembly 107 is provided on the welding head 104. The heat conduction assembly 107 is connected to the vortex tube structure 108.

The workpiece preheating assembly 102 is connected to the high-temperature flue gas recovery assembly 106.

[0026] In this embodiment, the high-temperature fume recovery component 106 absorbs the fume generated by welding and performs fume filtration. After filtration, the residual heat of the clean gas is accurately conducted and applied to the workpiece to be welded. Under the action of the workpiece preheating component 102, the workpiece gradually heats up and reaches a suitable initial welding temperature in advance. Secondly, the heat generated by welding of the welding head 104 is also conducted to the vortex tube structure 108 through the heat conduction component 107. After the vortex tube structure 108 performs cold and hot separation, the cold air flow passes through the cooling head structure 103 to dissipate heat. The fin structure 105 cools down, and the hot air flow is discharged through the annular air outlet head 1026. The discharged hot air flow contacts the heat-conducting fin structure 1025 with excellent thermal conductivity. The heat-conducting fin structure 1025 quickly transfers the heat of the hot air flow to the inside of the conveying hose 1022. After the heat flow inside the conveying hose 1022 absorbs this part of the heat, the temperature rises further, realizing the full utilization of the lost heat, avoiding energy waste, and truly realizing the all-round and multi-level recycling of energy, reflecting the advanced design concept of high efficiency, energy saving and environmental protection.

[0027] Working Principle: During welding, the drive motor 2014 drives the transmission gear 2013 to rotate, which in turn transmits power to the transmission ring gear 2012. The transmission ring gear 2012 drives the drive swivel 2015 to rotate, which in turn drives the feed tray 2016 to rotate. The feed tray 2016 drives the workpiece to the welding area, and then the welding robot 101 controls the welding head 104 to perform welding. The welding process generates high-temperature smoke, which allows the fan device 1061 to be drawn through the annular smoke recovery head 1064, so that the smoke is filtered through the filter structure 1062 and transported to the delivery hose 1022, and finally discharged through the hot air head structure 1021. Since the partition 203 can be sealed with the upper ring cover 2021 each time it is switched, it is beneficial to quickly preheat the workpiece, and the heat generated by the welding process of the welding head 104 can be conducted through the heat dissipation fin structure 105, and at the same time, a part of it is transferred to the heat conduction cavity structure 1071, so that the gas can be heated and transported to the heat conduction cavity structure 1071. The air enters the annular manifold structure 1072 and then enters the vortex tube structure 108, which divides the vortex tube structure 108 into two streams of hot and cold air. The cold air is discharged through the cooling head structure 103, so that the cold air quickly cools the heat dissipation fin structure 105. At the same time, the hot air is discharged through the annular air outlet head 1026, and then introduced into the delivery hose 1022 through the heat-conducting fin structure 1025 to increase the temperature, which is convenient for preheating the workpiece. After the temperature inside the heat-conducting cavity structure 1071 drops, the one-way air inlet head 1074 is used to intake air again to maintain a continuous gas supply. When the workpiece welding is completed, the feed tray 2016 transports the workpiece and transfers it, so that the preheated workpiece reaches the welding area for welding again. At the same time, the workpiece preheating operation is performed again in the previous step, and the welded workpiece is transported to the initial position for material removal.
