Where is the precision of Photovoltaic Welding Strip Rolling Mill reflected

The precision of photovoltaic welding strip rolling mill is reflected in multiple aspects, as follows:

1.High precision rolling system: The photovoltaic welding strip rolling mill adopts a servo control system, with a rolling pressure error of ≤± 5N, which can ensure the uniformity of the welding strip thickness. At the same time, some advanced rolling mills such as Jiangsu Youjuan's equipment adopt servo motor closed-loop control, with a response time of ≤ 0.01s and a roll system runout of ≤ 0.002mm. Its YQ-1200 photovoltaic welding strip precision rolling machine has a rolling accuracy error controlled within ± 0.02mm, and some rolling mills have a rolling accuracy of ± 0.01mm, far higher than the industry average level.

2.Accurate tin coating process: The high-speed tin coating machine is an important component of the photovoltaic strip rolling mill, and its tin coating accuracy also reflects the precision of the equipment. For example, Jiangsu Youjuan's high-speed tin coating machine has a tin coating speed of 250m/min and a tin layer thickness deviation of ≤ 0.003mm, ensuring the welding reliability of the solder strip. Some high-speed tin coating machines have a speed of up to 60m/min and a thickness deviation of less than 0.005mm for the tin coating layer.

3.Stable equipment performance: The key components of the equipment are made of imported wear-resistant materials, with a continuous operation failure rate of less than 0.5% per month, which can ensure 24-hour uninterrupted production, thereby ensuring stability in the production process and consistency in product quality.

4.Intelligent temperature control module: It has the function of real-time monitoring of rolling temperature, with temperature error controlled within ± 2 ℃, avoiding accuracy deviation caused by thermal deformation of the welding strip, further ensuring the accuracy and quality of the welding strip.

5.Accurate wiring and rewinding: In the welding strip rewinding process, the precision rewinding machine has a wiring accuracy of ≤ 0.1mm and a tension control error of ≤ ± 2N, which can avoid the entanglement and knotting of the welding strip, ensure neat winding, and improve the welding efficiency of downstream components.
