Description

Technical Field

[0001] The invention relates to the field of photovoltaic welding strip production, and in particular to photovoltaic welding strip tinning production equipment. Background Art

[0002] Photovoltaic welding ribbon, also known as tinned copper ribbon or tin-coated copper ribbon, is a branch current ribbon and interconnection strip. It is used to connect the solar cells of photovoltaic modules and plays an important role in conductivity and collection of 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 the photovoltaic module and has a great impact on the power of the photovoltaic module.

[0003] When tinning the existing photovoltaic welding strips, the photovoltaic welding strips are usually directly inserted into the tin pool for electroplating. The temperature of the tin liquid is high, and the surface is easily oxidized to form an oxide film. During electroplating, the coating is likely to contain tin oxide, which can easily lead to uneven tin plating and poor tin plating effect, affecting the subsequent performance of the photovoltaic welding strip. In addition, during the electroplating process, air is easily attached to the surface of the photovoltaic welding strip and brought into the tin pool. During electroplating, bubbles are easily formed on the surface of the photovoltaic welding strip, and the tin plating result is poor. After the photovoltaic welding strip is produced, it is directly placed outside. On the one hand, it is easy to be contaminated by external impurities. On the other hand, during the production process, the surface of the photovoltaic welding strip is easily adhered to impurities such as metal debris, and subsequent tin plating is prone to uneven coating.

[0022] 1. This photovoltaic welding strip tinning production equipment is provided with an undercurrent mechanism. The two rotating shafts are driven to rotate by a first motor, and the two rotating shafts drive multiple turbines to rotate. During the rotation of the turbine, the tin liquid at the bottom of the tin pool is driven to flow slowly, thereby forming an undercurrent.

When passing through the first curved tube and the second curved tube, the photovoltaic welding strip substrate will directly contact the tin liquid and will not bring air into the tin liquid. At the same time, the air supply pipe will continue to provide inert gas to the first curved tube and the second curved tube. The inert gas is blown in the opposite direction along the movement of the photovoltaic welding strip in the first curved tube, and the air attached to the photovoltaic welding strip is taken away, thereby avoiding the oxidation of the tin liquid, that is, avoiding the formation of an oxide film on the surface of the photovoltaic welding strip, and the tin plating of the photovoltaic welding strip is uniform, and the tin plating effect is better.

[0024] 3. This photovoltaic welding strip tinning production equipment is provided with a cleaning mechanism. When the inert gas is discharged from the first curved pipe, it is gathered through the wide bucket and brought into the cleaning box through the air collecting pipe, dried by the desiccant, and then purified by the inert gas purification membrane. Part of the inert gas can be recovered and reused, saving resources.

[0025] 4. This photovoltaic welding strip tinning production equipment is provided with a cleaning mechanism. The third motor drives the rotating shaft to rotate, the rotating shaft drives the two driving gears to rotate, the two driving gears drive the two racks to move, the racks drive the first connecting plate to move, the first connecting plate drives the two cleaning rollers to move relative to each other through the second connecting plate until they are in a suitable position. The distance between the cleaning rollers can be adjusted according to the thickness of the photovoltaic welding strip, and the applicable range is wide. Then, the fourth motor drives the two first gears to rotate in the opposite direction. During the rotation, the two second gears will be driven to rotate relative to each other, so that the surface impurities of the photovoltaic welding strip can be cleaned. During the subsequent electroplating, there will be no uneven plating.

[0026] The present invention can clean impurities on the surface of the photovoltaic welding strip, and no oxide film and bubbles will appear when the photovoltaic welding strip is tinned.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0036] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, this application proposes a photovoltaic solder strip tinning production equipment.

[0037] like Figure 1-7 As shown, a photovoltaic solder strip tinning production equipment comprises:

[0038] A tin pool 1, wherein the tin pool 1 is filled with molten tin;

[0039] In order to prevent the photovoltaic welding strip substrate from entering the tin liquid and preventing gas from adhering to it, a dark surge mechanism 2 is provided to drive the tin liquid to flow and take away the gas on the surface of the photovoltaic welding strip substrate. The dark surge mechanism 2 includes a partition 3 fixedly welded to the inside of the tin pool 1, and a rotating shaft 4 is provided on the upper and lower sides of the partition 3. Both ends of the two rotating shafts 4 are rotatably connected to the inner wall of the tin pool 1, and multiple turbines 5 are fixedly installed outside the two rotating shafts 4. It is worth mentioning that the turbines 5 outside the two rotating shafts 4 are arranged in reverse, and the multiple turbines 5 outside the same rotating shaft 4 are evenly distributed in an array. The right ends of the two rotating shafts 4 rotate through the tin pool 1 and are connected by a transmission mechanism 6. It should be noted that the transmission mechanism 6 includes two pulleys 23, and the two pulleys 23 are coaxially fixedly connected to the two rotating shafts 4 respectively, and the two pulleys 23 are connected by a synchronous belt transmission. A first motor 7 is fixedly installed outside the tin pool 1, and the drive shaft of the first motor 7 is coaxially fixedly connected to one of the rotating shafts 4;

[0040] Through the above technical features: in order to make the tin liquid flow and take away the gas on the surface of the photovoltaic welding strip substrate, the two rotating shafts 4 are driven to rotate by the first motor 7, and the two rotating shafts 4 drive multiple turbines 5 to rotate. During the rotation process, the turbine 5 drives the tin liquid at the bottom of the tin pool to flow slowly, thereby forming an undercurrent, which can directly take away the gas attached to the photovoltaic welding strip when it comes into contact with it.

[0041] In order to smoothly electroplate the photovoltaic welding strip, an electroplating mechanism 8 is provided for electroplating the photovoltaic welding strip. The electroplating mechanism 8 includes a first curved tube 9 and a second curved tube 10. Furthermore, a fixed pulley 24 is installed inside the first curved tube 9 and the second curved tube 10. The first curved tube 9 and the second curved tube 10 are filled with inert gas. The first curved tube 9 and the second curved tube 10 are both arranged at the opening position of the tin pool 1. The photovoltaic welding strip passes through the first curved tube 9 and extends to the inside of the tin pool 1, and then passes through the second curved tube 10 and extends to the outside of the tin pool 1. An air supply pipe 11 is provided above the tin pool 1. It should be noted that an electromagnetic valve is provided in the air supply pipe 11, and the air supply pipe 11 is connected to the first curved tube 9 and the second curved tube 10. It should be noted that the first curved tube 9 and the second curved tube 10 are transparent, so as to observe the thickness of the oxide film layer on the surface of the tin liquid inside and outside the first curved tube 9 and the second curved tube 10, so as to facilitate the staff to clean it regularly.

[0042] Through the above-mentioned technical features, the photovoltaic welding strip substrate is passed through the first curved tube 9 and the second curved tube 10 and continuously moved. When the photovoltaic welding strip substrate is between the first curved tube 9 and the second curved tube 10, it is inside the tin liquid and electroplating can be carried out at this time. The first curved tube 9 and the second curved tube 10 are both filled with inert gas. The tin liquid in the first curved tube 9 and the second curved tube 10 will not directly contact the external air. The photovoltaic welding strip substrate will directly contact the tin liquid when passing through the first curved tube 9 and the second curved tube 10, and will not bring air into the tin liquid, which has a good effect on the tin plating of the photovoltaic welding strip.

[0043] When tinning the photovoltaic welding material, it is necessary to recover and clean the inert gas introduced into the first curved pipe 9, so a cleaning mechanism 12 is provided for cleaning the inert gas. The cleaning mechanism 12 includes a cleaning box 13, a box cover 14 is installed on the cleaning box 13, and a filter plate 15 is installed in the cleaning box 13. It should be noted that the part of the cleaning box 13 located on the right side of the filter plate 15 is filled with a desiccant, and a stirring shaft 16 is provided on the right side of the filter plate 15. A second motor 17 is installed on the box cover 14, and the drive shaft of the second motor 17 rotates through the box cover. 14 is coaxially fixedly connected with the stirring shaft 16, an air outlet pipe 18 is provided in the middle position of the box cover 14, a plug plate 19 is provided on the box cover 14, an inert gas purification membrane is installed on the plug plate 19, an air collecting pipe 21 is installed on the right side of the lower end of the cleaning box 13, a wide bucket 22 is installed at the lower end of the air collecting pipe 21, the inlet of the first curved pipe 9 is arranged in the wide bucket 22, and the wide bucket 22 is provided with a perforation matching the photovoltaic welding strip, the air supply pipe 11 is connected with the cleaning box 13, it should be noted that the part where the air supply pipe 11 is connected to the cleaning box 13 is provided with a one-way valve.

[0044] Through the above-mentioned technical features, the gas supply pipe 11 will continuously provide inert gas to the first curved pipe 9 and the second curved pipe 10. The inert gas is blown in the reverse direction along the photovoltaic welding strip in the first curved pipe 9, and the air attached to the photovoltaic welding strip is taken away. At the same time, when the inert gas is discharged from the first curved pipe 9, it is gathered by the wide bucket 22 and taken into the cleaning box 13 through the air collecting pipe 21, dried by the desiccant, and then purified by the inert gas purification membrane, so that part of the inert gas can be recovered and reused.

[0045] Since impurities may adhere to the surface of the photovoltaic welding strip, a cleaning mechanism 25 is provided for cleaning the surface of the photovoltaic welding strip to prevent impurities from affecting subsequent tinning. The cleaning mechanism 25 includes two fixed plates 26, and the two fixed plates 26 are fixedly connected to the wide bucket 22. Two cleaning rollers 27 are provided between the two fixed plates 26. It is worth mentioning that the surface of the cleaning roller 27 is covered with a cleaning cloth. The two fixed plates 26 are provided with a through hole 28, and two sliders 29 are slidably connected in the two through holes 28. The two ends of the two cleaning rollers 27 rotate through the four sliders 29 to be rotatably connected. The two fixed plates 26 are provided with a driving mechanism 30 for driving the two cleaning rollers 27. It should be noted that the driving mechanism 30 includes two first gears 31 and two second gears 32. The two first gears 31 are meshingly connected, and the two first gears 31 are respectively meshed with the two second gears 32. The first gear 31 and the second gear 32 are connected, and a first connecting plate 33 and a second connecting plate 34 are respectively provided outside the first gear 31 and the second gear 32. The two first gears 31 are rotatably connected to the first connecting plate 33, and the meshing first gear 31 and the second gear 32 are rotatably connected to the second connecting plate 34. A rack 35 is slidably connected outside the fixed plate 26, and the rack 35 is fixedly connected to the first connecting plate 33. A rotating shaft 36 is rotatably penetrated between the two fixed plates 26, and two driving gears 37 are coaxially fixedly connected outside the rotating shaft 36. The two driving gears 37 are respectively meshed with the two racks 35. A third motor 20 is fixedly installed outside the fixed plate 26, and the driving shaft of the third motor 20 is coaxially fixedly connected to the rotating shaft 36. A fourth motor 38 is fixedly installed outside the second connecting plate 34, and the driving shaft of the fourth motor 38 rotates through the second connecting plate 34 and the first connecting plate 33 and is coaxially fixedly connected to the first gear 31.

[0046] Through the above technical features: the third motor 20 drives the rotating shaft 36 to rotate, the rotating shaft 36 drives the two driving gears 37 to rotate, the two driving gears 37 drive the two racks 35 to move, the racks 35 drive the first connecting plate 33 to move, the first connecting plate 33 drives the two cleaning rollers 27 to move relative to each other through the second connecting plate 34 until they are in a suitable position, the distance between the cleaning rollers can be adjusted according to the thickness of the photovoltaic welding strip, and then the two first gears 31 are driven to rotate in the opposite direction by the fourth motor 38, and the two second gears 32 are driven to rotate relative to each other during the rotation process, so that the surface impurities of the photovoltaic welding strip can be cleaned.

[0047] Working principle:

[0048] 1) Driving the tin liquid to flow: The first motor 7 drives the two rotating shafts 4 to rotate, and the two rotating shafts 4 drive the multiple turbines 5 to rotate. During the rotation process, the turbines 5 drive the tin liquid at the bottom of the tin pool to flow slowly, thereby forming an undercurrent;

[0049] 2) Inert gas is introduced into the first curved pipe 9 and the second curved pipe 10: the gas supply pipe 11 will continuously supply inert gas to the first curved pipe 9 and the second curved pipe 10. The inert gas moves in the first curved pipe 9 in the reverse direction of the photovoltaic welding strip, and takes away the air attached to the photovoltaic welding strip. At the same time, when the inert gas is discharged from the first curved pipe 9, it is gathered by the wide bucket 22 and taken into the cleaning box 13 through the air collecting pipe 21, dried by the desiccant, and then purified by the inert gas purification membrane, so that part of the inert gas can be recovered and reused.

[0050] 3) Removing impurities from the surface of the photovoltaic welding strip: The third motor 20 drives the rotating shaft 36 to rotate, the rotating shaft 36 drives the two driving gears 37 to rotate, the two driving gears 37 drive the two racks 35 to move, the racks 35 drive the first connecting plate 33 to move, the first connecting plate 33 drives the two cleaning rollers 27 to move relative to each other through the second connecting plate 34 until they are in a suitable position, the distance between the cleaning rollers can be adjusted according to the thickness of the photovoltaic welding strip, and then the four motors 38 drive the two first gears 31 to rotate in the opposite direction, and during the rotation process, the two second gears 32 will be driven to rotate relative to each other, so that the surface impurities of the photovoltaic welding strip can be cleaned;

[0051] 4) Electroplating the photovoltaic welding strip: After the photovoltaic welding substrate is cleaned by a cleaning mechanism, it passes through the first curved tube 9 and the second curved tube 10 and continues to move. When the photovoltaic welding strip substrate is between the first curved tube 9 and the second curved tube 10, it is inside the tin liquid and can be electroplated at this time. The first curved tube 9 and the second curved tube 10 are both filled with inert gas. The tin liquid in the first curved tube 9 and the second curved tube 10 will not directly contact the external air. When passing through the first curved tube 9 and the second curved tube 10, the photovoltaic welding strip substrate will directly contact the tin liquid for electroplating.
