Description

Technical Field

[0001] The utility model relates to the field of annealing devices, in particular to an annealing device for a photovoltaic welding strip double-head tinning machine. Background Art

[0002] In the process of manufacturing welding strips, annealing the copper substrate can effectively eliminate the stress accumulated during the material production process and prevent shape changes, cracks or performance degradation caused by stress concentration during subsequent processing (such as tinning) or use. Annealing can adjust and optimize the microstructure of metal materials and improve the plasticity and toughness of metals. Annealing removes impurities and oxide layers on the surface, ensures good adhesion of the tinning layer, and improves the electrical conductivity of the metal. Annealing can also prevent decarburization during high-temperature processing and keep the chemical composition of the material stable, thereby ensuring that its performance meets the requirements. Therefore, annealing equipment is crucial to the production of photovoltaic welding strips.

[0003] The diameter of ultra-fine photovoltaic welding ribbon is much smaller than that of conventional welding ribbon, so it is more likely to break due to various reasons during the annealing process, affecting production efficiency.

[0004] At present, in order to increase the unit machine output, "double-head tinning machines" are mostly used to produce ultra-fine photovoltaic welding ribbons.

[0005] In the annealing station, since there are two ultra-fine copper wires running at the same time, when one copper wire breaks accidentally, the falling / thrown copper wire will inevitably be entangled with the other copper wire, causing the other copper wire to break, causing the entire line to stop, seriously affecting production efficiency. Utility Model Content

[0006] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, an annealing device for a photovoltaic welding strip double-head tinning machine is provided.

[0007] The technical solution adopted by the utility model to solve the technical problem is: an annealing device for a photovoltaic welding strip double-head tinning machine, the annealing device is a double-head annealing device, including at least an even number of sets of annealing mechanisms, one set of annealing mechanisms is a first annealing mechanism, and the other set is a second annealing mechanism, the first annealing mechanism and the second annealing mechanism are arranged side by side, and the first annealing mechanism and the second annealing mechanism are operated either separately or simultaneously;

[0008] The first annealing mechanism includes a first pay-off wheel. The first wire material is routed from the pay-off position of the first pay-off wheel through the first annealing wheel, the first annealing water tank, the first nitrogen glass pipeline and the first blowing assembly, and then enters the next process through the second baffle.

[0009] The second annealing mechanism includes a second pay-off wheel. The second wire material is routed from the pay-off position of the second pay-off wheel through the first baffle, the second annealing wheel, the second annealing water tank, the second nitrogen glass pipeline and the second blowing assembly, and then enters the next process.

[0010] The first baffle is arranged on the upper part of the first annealing mechanism, and the second baffle is arranged on the upper part of the second annealing mechanism.

[0011] Further, a second pay-off wheel is arranged at the lower right of the first annealing mechanism, a first annealing wheel is installed on the upper side of the second pay-off wheel, a first annealing water tank is arranged at intervals between the second pay-off wheel and the left side of the first annealing wheel, a first nitrogen glass pipe and a first blowing assembly are arranged at intervals between the first annealing water tank and the second pay-off wheel and the first annealing wheel, the first nitrogen glass pipe is arranged vertically in the interval, the first blowing assembly is arranged at an opening position at one end of the first nitrogen glass pipe, and the first baffle is arranged at the top of the first annealing mechanism;

[0012] A first pay-off wheel is arranged on the right side of the first annealing mechanism, and the first pay-off wheel is arranged at an interval with the second pay-off wheel;

[0013] A second annealing water tank is arranged on the left side of the second annealing mechanism, a second annealing wheel is arranged at intervals on the right side of the second annealing water tank, a second nitrogen glass pipe and a second blowing assembly are arranged at the interval between the second annealing water tank and the second annealing wheel, the second nitrogen glass pipe is arranged vertically in the interval, the second blowing assembly is arranged at an opening position at one end of the second nitrogen glass pipe, and the second baffle is arranged at the top of the second annealing mechanism.

[0014] Furthermore, the first annealing mechanism and the second annealing mechanism also include a plurality of guide wheels for guiding the wires.

[0015] Furthermore, the first baffle and the second baffle are both in the shape of long strips, and are both horizontally installed at the top of the first annealing mechanism and the second annealing mechanism.

[0016] The beneficial effects of the utility model are as follows: the utility model provides an annealing device for a photovoltaic welding strip double-head tinning machine, which adds a baffle design on the basis of the existing layout, and does not cause more serious consequences when the wire is broken;

[0017] The wiring layout is redesigned on the double-head design, and the first baffle and the second baffle are installed. When a wire break occurs at either end, they are blocked by their respective baffles to prevent the first wire and the second wire from being entangled with each other, thereby reducing the time for subsequent processing and not affecting the normal operation of the normal annealing mechanism.

[0018] In summary, the utility model has a simple structure, a reasonable layout and can effectively shorten the subsequent processing time after the wire is broken, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
