Description

Technical Field

[0001] The utility model relates to the technical field of solar cell production equipment, in particular to a solar cell welding ribbon welding device. Background Art

[0002] Welding, also known as welding, is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. The function of solar cell ribbons is to connect multiple battery cells on solar cells to form an efficient power generation circuit. In addition, solar cell ribbons also have good electrical conductivity and corrosion resistance, and can be used for a long time in outdoor environments without damage.

[0003] During the welding process of the solar cell ribbon, the solar cell is usually fixed by a clamp, and then the solar cell ribbon is placed at the connection between the two solar cells. After that, the operator holds the welding machine to heat the solar cell ribbon to melt the solar cell ribbon, thereby connecting the two solar cells.

[0004] In the existing work of welding solar cell ribbons, although the operator can heat the solar cell ribbons by holding a welding machine, the operation is cumbersome and can easily cause harm to the workers if the operation is improper. Some solar cell ribbon welding devices adjust the position of the laser welding machine through adjustment devices such as hydraulic rods. Although it replaces the method of heating the solar cell ribbon with a handheld welding machine by the operator, the adjustment range is relatively large and the accuracy is relatively low. The problem of welding quality is often affected by the close distance between the laser welding machine and the solar cell ribbon. For this reason, we propose a solar cell ribbon welding device.
