Abstract

The invention discloses a constant tension device and a use method thereof. The device comprises a case (1), two rubber wheels (2), a front positioning wheel (3), a rear positioning wheel (4), two middle positioning wheels (5), a cover plate (6) and oscillating bar mechanisms (7), wherein the front positioning wheel (3) is arranged on the top of the left side of the case (1); the rear positioning wheel (4) and the front positioning wheel (3) are arranged at the bottom of the right side of the case (1) in parallel; the two rubber wheels (2) and the front positioning wheel (3) are arranged on the upper part of the case (1) in parallel; the two middle positioning wheels (5) and the front positioning wheel (3) are arranged at the bottom of the case (1) in parallel; the cover plate (6) is arranged on the top of the case (1); and the cover plate (6) is provided with two rows of oscillating bar mechanisms (7). The device has a simple, reasonable and compact structure, thereby overcoming the multiple defects in the prior art and achieving the advantages that the tension of a tin-plated copper belt is effectively controlled, use is convenient, cost is low, and efficiency is high.

Description

technical field [0001] The invention relates to a constant tension device and its usage method, in particular to a constant tension device for controlling the surface tension of a copper strip and its usage method. Background technique [0002] Solar energy is recognized as green energy, and the photovoltaic industry based on solar energy has developed rapidly at home and abroad in recent years. Tin-coated copper strip (also known as solder strip) is a key component in solar cells in the photovoltaic industry. It has a crucial impact on the energy efficiency and service life of solar cells. Therefore, the quality and performance of tin-coated copper strips are high. At present, the vast majority of welding strip manufacturers in China use the production process of free unwinding of copper strips. The surface tension of copper strips is uncontrollable and the quality is not stable enough. The state of the copper strip is different, and the required tension is different. The ...
