Technical Field

[0001] The utility model relates to the technical field of photovoltaic solder tapes, in particular to a cutting device for photovoltaic solder tapes. Background Art

[0002] Photovoltaic solder tapes, also known as tin-plated copper tapes or tin-coated copper tapes, are divided into bus bars and interconnecting bars, which are connection materials between the battery cells of photovoltaic modules and play an important role in conducting and collecting electricity. The cutting of photovoltaic solder tapes is an important link in the manufacturing process of photovoltaic modules, which involves cutting the photovoltaic solder tapes according to specific lengths or shapes to ensure that the size and shape of the solder tapes meet the design requirements of the photovoltaic modules.

[0003] The above device does not have a structure for preventing loosening of the solder tape during loading when in use. When cutting existing photovoltaic solder tapes, an automatic cutting can be achieved only by using a cutting machine. However, since the solder tape loading on the cutting machine is a traction type loading, the solder tape roll is extremely likely to rotate too many circles or angles, resulting in excessive material discharge. As a result, the relatively loose solder tape will shift or bend during the moving loading process, affecting the cutting effect or accuracy. Based on the existing technical deficiencies, the utility model designs a quick-drying device for photovoltaic solder tapes. Summary of the Utility Model

[0024] By providing the tensioning roller 306, the first guiding roller 307 and the second guiding roller 308, it is convenient to guide the welding tape, so that the welding tape can move horizontally on 1 and be cut.

[0027] Working principle: When a cutting device for photovoltaic solder tapes is in use, in the initial state, first, the control panel 101 and the start-stop button 102 are set on the front of the cutting machine body 1. At the top of the cutting machine body 1, there are also a front guiding component 103, a rear guiding component 104, a feeding roller group 105, and a cutting knife group 106 to facilitate the cutting of photovoltaic solder tapes. On the rotating shaft 201 connected to the outer end of the support arm 2, a first clamping piece 202 and a second clamping piece 203 are installed, and fixing rings 204 and fixing bolts 205 are installed on both the first clamping piece 202 and the second clamping piece 203 to facilitate the adjustment of the distance between the first clamping piece 202 and the second clamping piece 203 and thus install and fix solder tape reels of different widths.
