Description
Technical field:
The utility model belongs to technical field of nonferrous metal processing, relates in particular to a kind of special soft copper band annealing device.
Background technology:
Special soft copper band is the important conductive heat conducting material that solar module uses, and is mainly used in the interconnecting strip of manufacturing solar cells.Special soft copper band not only requires to have the favorable conductive thermal conductivity, high tolerance of dimension and surface quality, good comprehensive mechanical property; Compare with general oxygen-free copper stripe and also to require having higher zinc-plated performance, good welding property and special soft characteristics, need advanced production technique do guarantee.
In the production process of special soft copper band, adopt the bell-jar lehre that the phenomenon of adhesive tape often takes place, cause the hardness of copper strips can't satisfy the technical requirements of HV≤50.
The utility model content:
The purpose of the utility model is to address the above problem, and a kind of special soft copper band annealing device is provided, and its device can satisfy the production needs of special soft copper band, and equipment is simple, and production cost is low, and tissue is produced flexibly.
To achieve these goals, the utility model is realized through following technical scheme:
A kind of special soft copper band annealing device comprises the pay-off unit, heating unit, cooling unit, passivation unit, drying unit and the take-up unit composition that are flow line successively and are provided with.
In heating unit, be provided with wire spiral, accomplish the heating of copper strips through wire spiral.
Be built-in with recirculated water at cooling unit.Cooling unit is cooled to room temperature through recirculated water control with copper strips.
The passivation unit adopts spray passivation device, and spray water adopts the passivating solution of heating, recycles.Make strip surface form layer protecting film, prevent the band oxidation.70-80 ℃ of passivating solution temperature, temperature is controlled automatically.
Be provided with two pairs of extrusion rolls in the unitary outlet of passivation, guarantee to extract effect, passive film is evenly distributed.
Drying unit is used for the moisture evaporation with copper strip surface existence after the passivation, prevents oxidation in air.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings:
Fig. 1 is the described a kind of special soft copper band annealing device of the utility model.
Embodiment:
As shown in Figure 1, a kind of special soft copper band annealing device comprises the pay-off unit 1, heating unit 2, cooling unit 3, passivation unit 4, drying unit 5 and take-up unit 6 compositions that are flow line successively and are provided with.In heating unit 2, be provided with wire spiral, be built-in with recirculated water at cooling unit 3.
During work, width is the copper strips of 20～50mm, earlier through pay-off unit 1; Get in the heating unit 2, in the heating unit 2 wire spiral is arranged, produce heat behind the feeding electric current; Copper strips is heated recrystallize takes place to make it softening, the copper strips temperature after the heating is higher, in order to prevent its oxidation; Need cool off, be built-in with recirculated water, make the temperature of copper strips be reduced to room temperature through recirculated water at cooling unit 3; In order to prevent to guarantee the high-quality surface quality of copper strips, copper strips to be sent into passivation unit 4 carry out Passivation Treatment, take-up is carried out in oven dry again after the passivation.The passivation unit 4 preferred spray passivation devices that adopt, spray water adopts the passivating solution of heating, 70-80 ℃ of passivating solution temperature, temperature is controlled automatically, recycles.Through passivation, make strip surface form layer protecting film, prevent the band oxidation.Outlet in passivation unit 4 is provided with two pairs of extrusion rolls 7, and its effect is to guarantee to extract effect, and passive film is evenly distributed.Through drying unit 5, the moisture evaporation of copper strip surface is complete, prevent the copper strips oxidation, get into take-up unit 6 at last.
