Description

Technical Field

[0001] This utility model relates to the field of busbar welding, specifically to an air-cooled welding head. Background Technology

[0002] During the production of photovoltaic equipment, the temperature of the welding head rises during the welding of busbars, and failure to cool it down in time will damage the welding head. This utility model provides an air-cooled welding head. The air-cooling channel of the traditional welding head cooling device runs through the top and bottom of the welding head. For example, Chinese Utility Model Patent Publication No.: "CN 201862918 U", entitled: Air-cooled Welding Head, wherein the cross-section of the upper half of the welding column is smaller than the cross-section of the lower half; the air-cooling channel runs through the upper and lower ends of the welding column. By setting the air-cooling channel in the welding column, this method of cooling the welding head is complex to manufacture and has a high equipment cost. Utility Model Content

[0003] To address the issues of complex manufacturing and high equipment costs associated with traditional air-cooled welding head cooling methods, this invention proposes an air-cooled welding head, the specific solution of which is as follows:

[0004] The air-cooled welding head includes a heat dissipation duct, a mounting plate, and heat dissipation fins; the heat dissipation duct is located inside the mounting plate, the heat dissipation fins are located on the upper surface of the mounting plate, and the bottom of the heat dissipation fins is connected to the upper surface of the mounting plate.

[0005] By opening heat dissipation air channels inside the mounting plate, the welding head is cooled by cold air. Furthermore, the heat dissipation fins on the upper surface of the mounting plate increase the heat dissipation area of ​​the welding head, thus shortening the cooling time and improving the cooling effect.

[0006] Furthermore, the heat dissipation air duct includes a first air duct and a second air duct. The first air duct and the second air duct are connected to each other and run through the inside of the mounting plate. The first air duct is parallel to the mounting plate, and the second air duct is perpendicular to the mounting plate.

[0007] Specifically, the heat dissipation air duct also includes a third air duct, which is installed on the mounting plate and is connected to the first air duct.

[0008] By creating three sets of heat dissipation air ducts inside the mounting plate, and connecting the three sets of air ducts to form gas convection, the cooling speed of the welding head is accelerated.

[0009] Preferably, the air-cooled welding head also includes a baffle plate, which is disposed at the bottom of the mounting plate and is fixedly connected to the bottom of the mounting plate. In this embodiment, there are two baffle plates.

[0010] By setting a baffle plate at the bottom of the mounting plate, dust and debris generated during equipment operation can be effectively prevented from entering the welding head, keeping the inside of the welding head clean.

[0011] Specifically, the bottom of the mounting plate is provided with several welding heads, which are fixedly connected to the bottom of the mounting plate and between the two blocking plates.

[0012] Furthermore, a second air duct is provided between each pair of welding heads.

[0013] By setting a second air duct between every two welding heads, the overall cooling effect of the welding head is further enhanced.

[0014] By installing baffles on the bottom of the mounting plate and on both sides of the welding head, the dust and debris generated during equipment operation are blocked, and the stability of the equipment is increased. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0021] This utility model proposes an air-cooled welding head, including a heat dissipation duct, a mounting plate 22, and heat dissipation fins 11; wherein the heat dissipation duct is disposed inside the mounting plate 22, the heat dissipation fins 11 are disposed on the upper surface of the mounting plate 22, and the heat dissipation fins 11 are connected to the upper surface of the mounting plate 22.

[0022] To address the complexity and high cost of traditional heat-dissipating welding head manufacturing methods, this invention employs an air-cooled welding head. A heat dissipation airflow channel is created inside the mounting plate 22, and the welding head 33 is cooled by gas convection within the channel, thus accelerating the cooling effect. Figure 1 As shown: In this embodiment, heat dissipation fins 11 are installed on the upper surface of the mounting plate 22, and several welding heads 33 are provided at the bottom of the mounting plate 22. The welding heads 33 are fixedly connected to the bottom of the mounting plate 22. The heat dissipation fins 11 increase the heat dissipation area of ​​the mounting plate 22, making the cooling effect of the welding heads 33 better. This solves the problem of the complexity of the traditional cooling welding head manufacturing method and saves equipment costs.

[0023] In order to achieve the connection of the air duct, such as Figure 4 As shown: The heat dissipation airflow includes a first airflow duct S and a second airflow duct 15. The first airflow duct S and the second airflow duct 15 are interconnected and pass through the interior of the mounting plate 22. The first airflow duct S is parallel to the mounting plate 22, and the second airflow duct 15 is perpendicular to the mounting plate 22. In this embodiment, the heat dissipation airflow also includes a third airflow duct 16, which is also installed in the mounting plate 22 and is located on one side of the heat dissipation fins 11. The third airflow duct has an air passage interface to facilitate the connection of the entire heat dissipation airflow with the external air passage. The third airflow duct 16 is connected to the first airflow duct S, such as... Figure 4 As shown: It can be seen that the three heat dissipation air channels inside the mounting plate 22 are interconnected and run through the entire interior of the mounting plate 22. Under the guidance of the heat dissipation air channels, the high-pressure gas is blown towards the welding head 33, achieving the cooling effect of the welding head 33.

[0024] To protect the stability of the welding process of welding head 33, such as Figure 2 As shown: The air-cooled welding head also includes baffle plates 13, which are located at the bottom of the mounting plate 22 and are fixedly connected to the mounting plate 22; there are two baffle plates 13. By setting baffle plates 13 at the bottom of the mounting plate 22, dust and debris generated during equipment operation can be effectively prevented from entering the welding head 33, keeping the inside of the welding head 33 clean and preventing contamination of the welding head 33; the welding head 33 is installed between the two baffle plates 13, and a heat dissipation air duct is provided between each pair of welding heads 33. By providing a second air duct 15 between each pair of welding heads 33, heat dissipation air ducts exist between each pair of welding heads, allowing heat dissipation from both sides of a single welding head, improving the heat dissipation effect of the welding head and ensuring welding quality.
