Rolling and tinning production line of triangular special-shaped soldering strip for photovoltaic panels and its production process

Abstract

The invention relates to a production line for calendering and tinning triangular special-shaped solder strips for photovoltaic panels and its production process, including a wire-releasing mechanism, a three-head wire drawing mechanism, a calendering mechanism, an annealing mechanism, a tinning cooling mechanism, and a wire-receiving mechanism. The wire is sent to the three-head wire drawing mechanism for wire drawing and extrusion, then sent to the calendering mechanism for calendering and flattening, then sent to the annealing mechanism for annealing treatment, then to the tinning cooling mechanism for tinning cooling, and finally sent to the take-up mechanism for winding . The advantage is that the three sets of wire drawing mechanisms carry out multi-stage stretching to avoid the problem of wire breakage; the upper pressure roller is designed with an annular rubber sleeve, and the winding method of the guide wheel of the annealing mechanism ensures that the welding belt does not turn over, ensuring the processing accuracy of the product; the height adjustment mechanism of the guide wheel is controlled Adjust the height of the wire guide wheel, workers do not need to climb up when threading, safe and reliable; the telescopic mechanism controls the drum to move left and right with the take-up reel, to achieve uniform wire take-up and wiring, to ensure that the triangular special-shaped welding ribbon is not deformed, and to improve product quality .

Description

technical field [0001] The invention relates to the field of production of triangular special-shaped welding strips, in particular to a calendering and tinning production line of triangular special-shaped welding strips for photovoltaic panels and a production process thereof. Background technique [0002] In order to improve the photoelectric conversion efficiency of photovoltaic panels, the new photovoltaic triangular special-shaped ribbon is composed of triangular sections and flat sections of copper wires. Its length has particularly strict control requirements according to process requirements. The main production process ;Wire-drawing-calendering-annealing-tinning-cooling-storage-winding. [0003] In the past, the drawing of triangular special-shaped ribbons for photovoltaic panels was to draw the copper wires through the drawing die to form copper wires of the required size and diameter. During the drawing process, it was necessary to ensure that the drawing wires wou...

AI Technical Summary

Problems solved by technology

The current method is to naturally cool the tinned solder strip in the air during the conveying process. The air cooling of the tinned solder strip requires a certain height and distance to realize the cooling of the tinned solder strip. Height, the tinned solder ribbon is bypassed from above, and the height of the wire passing guide wheel is the temperature required for cooling, but the height of the wire passing guide wheel is fixed and relatively high, and the staff must use a ladder to climb very high for operation every time the wire is wound. It is very inconvenient, and it is very inconvenient to adjust the fixed height of the wire guide wheel and adjust the cooling effect in different seasons

[0007] In the past, the triangular special-shaped ribbon take-up mechanism used for photovoltaic panels took up the wire by fixing the take-up plate on the drum and rotating the take-up. The wire arrangement is a special cable arrangement. The guide wheel drives the triangle special-shaped welding by moving left and right. The belt swings left and right at a uniform speed to achieve uniform wiring on the take-up reel, but this operation has a defect that the cable arrangement mechanism needs to pull the triangular special-shaped ribbon to shift left and right, which will cause deformation of the triangular special-shaped ribbon and cause problems in product quality

For example, the patent 201922041618.3, a winding device of a ball welding ribbon production equipment, can automatically take up the wire and change the disc automatically. The automatic winding adopts the above method, but it is very easy to cause deformation of the triangular special-shaped welding ribbon.
