[0002] Photovoltaic welding ribbon is also called tinned copper ribbon or tin-coated copper ribbon. It is divided into collector ribbon and interconnection ribbon. It is used to connect the solar cells of photovoltaic modules and plays an important role in conducting electricity. The welding ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the welding ribbon will directly affect the current collection efficiency of photovoltaic modules. After searching, the prior art (Announcement No.: CN202320994403.7) is a cooling device for the production of photovoltaic welding ribbon. The article records that "by setting a booster pump, a Y-shaped tube, a first concave frame, a long nozzle and a filter, when in use, the tinned copper ribbon is pulled to Above the box, the guide rollers on both sides lift the copper belt and play a guiding role at the same time. When the copper belt passes through the first concave frame, it passes directly between the two groups of long nozzles. The booster pump draws the coolant in the coolant tank and sends it to the long nozzle through the Y-shaped pipe. The upper and lower groups of long nozzles spray coolant toward the copper belt at the same time, so that the copper belt is cooled quickly and the residual pickling liquid on the surface of the copper belt is washed away. The filter filters the residual impurities in the coolant tank, realizing the function of facilitating flushing and cooling. However, the photovoltaic welding belt that is stretched and pulled straight in the prior art is easily broken due to the external force of the nozzle flushing. Summary of the invention

[0003] In order to overcome the defects of the prior art, a cooling device for photovoltaic welding ribbon production is provided to solve the problem that the photovoltaic welding ribbon stretched and pulled in the prior art is easily broken due to the external force of nozzle flushing.

[0004] In order to achieve the above-mentioned object, a cooling device for photovoltaic ribbon production is provided, comprising: a photovoltaic ribbon cooling pool and a drainage chamber, wherein the right end of the photovoltaic ribbon cooling pool is provided with a drainage chamber. Two groups of guide oblique blocks are symmetrically fixed on the inner wall of the photovoltaic welding strip cooling pool, and a liquid guide arc surface is arranged on the inclined surface of the guide oblique block. A first cooling water pipe is connected to the side of the guide oblique block, and the first cooling water pipe is connected to an arc groove through an infusion cavity, and the arc groove is distributed on the upper arc surface of the liquid guide arc surface. The inner wall of the photovoltaic welding strip cooling pool is connected to a liquid drainage roller through a fixed frame axis, and a water outlet is arranged on the lower surface of the fixed frame, and sponge rings are equidistantly sleeved on the surface of the liquid drainage roller.

[0005] Furthermore, three groups of conveying rollers are installed inside the photovoltaic welding ribbon cooling pool, and a conveying belt is installed between the photovoltaic welding ribbon cooling pool and the drainage chamber.

[0006] Furthermore, an exhaust hood is fixed above the conveyor belt, a fan is installed on the upper end surface of the exhaust hood, and the drainage roller is located at the upper left end of the conveyor belt.

[0007] Furthermore, a waste liquid recovery pipe is connected to the left end of the photovoltaic welding strip cooling pool, and the right side of the photovoltaic welding strip cooling pool is connected to the bottom of the inner cavity of the drainage chamber through a water inlet groove.

[0008] Furthermore, an infusion cavity is provided on the inner side of the diversion oblique block; and the infusion cavity is connected to three groups of arc grooves, and the diversion arc surface is an outwardly convex arc.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Reference Figures 1 to 4 As shown, the present invention provides a cooling device for photovoltaic ribbon production, comprising: a photovoltaic ribbon cooling pool 1 and a drainage chamber 3, wherein the right end of the photovoltaic ribbon cooling pool 1 is provided with the drainage chamber 3, Two groups of guide bevel blocks 4 are symmetrically fixed on the inner wall of the photovoltaic welding strip cooling pool 1. A liquid guiding arc surface 43 is arranged on the inclined surface of the guide bevel block 4. A first cooling water pipe 42 is connected to the side of the guide bevel block 4. The first cooling water pipe 42 is connected to an arc groove 44 through an infusion cavity 41. The arc groove 44 is distributed on the upper arc surface of the liquid guiding arc surface 43.

A water outlet port 53 is arranged on the lower surface of the fixed frame 51. Sponge rings 55 are equidistantly sleeved on the surface of the liquid discharge roller 5.

[0019] The photovoltaic welding strip entering the photovoltaic welding strip cooling pool 1 first contacts with the cooling water flowing on the liquid guiding arc surface 43 of the left guide bevel block 4 to cool down, and then is immersed in the cooling water in the photovoltaic welding strip cooling pool 1, and then contacts with the cooling water flowing on the liquid guiding arc surface 43 of the right guide bevel block 4 to cool down, and then comes to the upper surface of the left side of the conveyor belt 31, and the cooling water flowing down from the lower surface of the slowly rotating drainage roller 5 flows to the surface of the photovoltaic welding strip for final cooling, and after cooling, enters the drainage chamber 3 for drainage and then output.

[0020] In this embodiment, three groups of conveying rollers 11 are installed inside the photovoltaic welding strip cooling pool 1, and a conveying belt 31 is installed between the photovoltaic welding strip cooling pool 1 and the drainage chamber 3. An exhaust hood 33 is fixed above the conveying belt 31, and a fan 32 is installed on the upper end surface of the exhaust hood 33.
