Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.
Referring to fig. 1, the embodiment provides a photovoltaic solder strip production apparatus, which is used for performing drawing forming and annealing processing on a copper strip 100, and can solve the problems that in the prior art, the photovoltaic solder strip forming and annealing processing cycle is long, and a photovoltaic solder strip finished product is easy to deform after annealing processing. The photovoltaic solder strip production device can comprise a drawing mechanism 1, an annealing mechanism 2 and a shaping mechanism 3 which are sequentially arranged along the processing and transmission direction of the copper strip 100. The input end of the drawing mechanism 1 is used for receiving the copper strip 100 to be processed and drawing and shaping the copper strip 100 to output a strip blank 200 with the external dimension consistent with that of a finished photovoltaic welding strip. The input end of the annealing mechanism 2 receives the strip blank 200 output by the drawing mechanism 1 and is connected with the strip blank 200 so as to anneal the strip blank 200; the input end of the shaping mechanism 3 receives the annealed strip 200 output by the annealing mechanism 2, so as to trim the appearance of the strip 200 and output a finished photovoltaic welding strip.
The photovoltaic solder strip production device divides the forming processing of the copper strip 100 into two stages, namely a drawing mechanism 1 and a shaping mechanism 3. The drawing mechanism 1 is arranged at the upstream of the annealing mechanism 2, and can directly form the unheated copper strip 100 into the strip blank 200, and the strip blank 200 has better surface quality and mechanical property due to high cold-processing deformation strength. After the internal residual stress of the strip 200 during the drawing forming is removed by the annealing processing of the annealing mechanism 2, the external dimension of the strip 200 is trimmed again by the shaping mechanism 3 so as to meet the requirement of the design dimension of the finished product. Therefore, the photovoltaic solder strip production device can directly machine and form the photovoltaic solder strip and carry out annealing treatment, and the processing period of the photovoltaic solder strip is shortened; meanwhile, the size precision, the surface quality and the mechanical property of the produced photovoltaic solder strip can be ensured.
Specifically, based on the size of the copper strip 100 raw material, the size of the finished photovoltaic solder strip, and other factors, the drawing mechanism 1 may include one or more drawing dies, and obtain the strip blank 200 by one-step forming or multiple gradual diameter reduction forming. For example, the drawing mechanism 1 may include a first drawing die 11 and a second drawing die 12, wherein an input end of the first drawing die 11 receives the copper strip 100 unwound from the unwinding roll wound with the copper strip 100 and disposed upstream of the drawing mechanism 1, and shrinks and shapes the copper strip 100 and outputs a semi-formed strip blank; the input end of the second drawing die 12 receives the semi-formed strip blank output by the first drawing die 11, so as to perform shaping processing on the semi-formed strip blank and output the strip blank 200 with the same external dimension as the finished photovoltaic solder strip after being drawn. It should be noted that the mold cores of the first drawing mold 11 and the second drawing mold 12 may have mutually copying shaped areas, and the cross-sectional shapes of the shaped areas may be triangular, flat, regular polygonal, or trapezoidal, that is, the photovoltaic solder strip production apparatus provided in this embodiment may produce not only photovoltaic solder strips of conventional shapes, but also special-shaped photovoltaic solder strips by selecting drawing mechanisms of different mold cavity shapes. Taking the first drawing die 11 shown in fig. 2 as an example, a general drawing die includes a diameter-reducing zone 111 and a sizing zone 112. The metal wire (e.g., copper strip) is reduced in diameter and deformed to a desired shape and size as it is drawn through reducing section 111, and a sizing section 112 is located in the die core of the drawing die downstream of reducing section 111 for shaping the metal wire into a desired shape and size. Therefore, in this embodiment, the cores of the first drawing die 11 and the second drawing die 12 may have mutually profiling shaped areas 112, which may be understood as that the size of the shaped area 112 of the first drawing die 11 is larger than that of the shaped area of the second drawing die 12, so that the second drawing die 12 performs the diameter reduction process on the copper strip 100 again, or that the size of the shaped area 112 of the first drawing die 11 is consistent with that of the shaped area of the second drawing die 12, so that the second drawing die 12 performs the size and shape bundling process on the copper strip 100 again, and thus the strip blank 100 with better surface quality is obtained. The shaping mechanism can be a shaping die with a shaping channel with a cross-sectional shape matched with that of the finished photovoltaic solder strip. Drawing die and plastic mould have obtained extensive application in the prior art in the photovoltaic field, can select for use common drawing die and plastic mould as required in this embodiment, so drawing die and the concrete structure of plastic mould are no longer repeated here. In addition, the photovoltaic solder strip production apparatus may further include a reel 4 disposed downstream of the shaping mechanism 3 and used for winding the finished photovoltaic solder strip.
In the present embodiment, the annealing mechanism 2 may include a cooling water tank 21, and a first annealing wheel 22, a glass tube 23, and a second annealing wheel 24 that are sequentially provided in the conveyance direction of the strip 200. One of the first annealing wheel 22 and the second annealing wheel 24 is electrically connected to the positive electrode of the power supply, and the other of the first annealing wheel 22 and the second annealing wheel 24 is electrically connected to the negative electrode of the power supply, so as to heat the strip 200 between the first annealing wheel 22 and the second annealing wheel 24. The red hot strip 200 between the first annealing wheel 22 and the second annealing wheel 24 is inserted into the glass tube 23, and is protected by the glass tube 23 to prevent the red hot strip 200 from being oxidized. The lower edge of the second annealing roller 24 is located below the surface of the cooling liquid in the cooling water tank 21 to cool the heated strip 200 wound around it. Wherein the strip 200 is reciprocally wound on at least one of the first annealing wheel 22 and the second annealing wheel 24 to move in the conveying direction thereof by being driven by the wound first annealing wheel 22 and/or second annealing wheel 24, it can be understood that at least one of the first annealing wheel 22 and the second annealing wheel 24 may serve as a driving wheel for drawing the strip 200 and moving the strip 200 in the conveying direction. Preferably, both the first annealing wheel 22 and the second annealing wheel 24 may be disposed within an inert atmosphere environment to further prevent oxidation of the strip 200.
In a preferred embodiment, the annealing mechanism 2 may further include a first surface treatment unit 25 disposed between the glass tube 23 and the second annealing wheel 24, and the first surface treatment unit 25 includes a first working space for spraying a corrosion-resistant and/or oxidation-resistant material on the surface of the strip 200, and the first working space has a vacuum or inert atmosphere environment. Further, the annealing mechanism 2 may further include a second surface treatment unit 26 disposed between the second annealing wheel 24 and the shaping mechanism 3, and the second surface treatment unit 26 includes a second working space for spraying the brightening material on the surface of the strip 200, and the second working space has a vacuum or inert atmosphere environment. It should be noted that the first surface treatment unit 25 and the second surface treatment unit 26 are not limited to be understood as the treatment of spraying the corrosion-resistant and/or oxidation-resistant material and the brightening material only or only in a specific sequence on the surface of the strip 200. That is, the first surface treatment unit 25 and the second surface treatment unit 26 may be used to perform other surface treatments on the strip 200, or to exchange the treatment modes, i.e., contents, of the both. Preferably, the second surface treatment unit 26 located downstream of the cooling water bath 21 may further include at least one air nozzle for blowing the cooling liquid to the surface of the strip 200, the air nozzle being communicated with an air supply source. For example, the nozzles may be arranged around the circumference of the strip 200 with their air injection directions inclined toward the cooling water tank 21.
The working method of the photovoltaic solder strip production device provided by the embodiment is as follows:
firstly, the copper strip 100 enters the first drawing die 11 from the input end of the first drawing die 11, and the copper strip is subjected to diameter reduction and bundling by the first drawing die 11 to obtain a semi-finished strip blank. After the semi-finished strip is bundled and shaped by the second drawing die 12, the strip 200 with the same external dimension as the finished photovoltaic solder strip is formed.
Then, the strip 200 is annealed and surface-treated by passing through the first annealing wheel 22, the first surface treatment unit 25, the glass tube 23, the second annealing wheel 24, the cold water tank 21, and the second surface treatment unit 26 in this order. Wherein, the strip base 200 twines many times on first annealing wheel 22 and second annealing wheel 24 to make it can be drawn the removal by first annealing wheel 22 and/or second annealing wheel 24 as the action wheel, simultaneously, be located first annealing wheel 22 and/or second annealing wheel 24 support your strip base 200 and receive the red thermalization of electricity and then get into the cooling trough cooling, in order to realize annealing.

Also, the first annealing wheel 22, the first surface treatment unit 25, the glass tube 23, the second annealing wheel 24, and the second surface treatment unit 26 each have an inert gas or vacuum atmosphere capable of blocking the direct contact of the strip 200 with air to prevent the oxidation of the strip 200.
And then, the annealed strip blank 200 enters a shaping die to be subjected to final shape shaping, so that the shape of the strip blank meets the design requirement, and the finished photovoltaic welding strip is obtained.
And finally, the finished photovoltaic solder strip penetrates into the reel 4 and is wound by the reel 4.
