Description

Technical Field

[0001] The present invention relates to the technical field of tin coating, and in particular to a photovoltaic welding ribbon tin coating device with a winding and anti-wear function. Background Art

[0002] With the development of society, the photovoltaic industry based on solar energy has been rapidly developed at home and abroad in recent years. Due to the decreasing conventional energy, the search for unconventional energy has become a topic of concern to all countries. Solar energy, as an inexhaustible clean energy, has been valued by countries around the world and has become a great possibility to replace conventional energy. Therefore, the solar photovoltaic industry has developed rapidly. Solar photovoltaic welding ribbons, as an important component of photovoltaic panels, play an extremely important role in the energy conversion efficiency of solar energy and the service life of photovoltaic panels. Therefore, the production requirements for photovoltaic welding ribbons are very high.

[0003] Traditional tinning methods for solar photovoltaic ribbons have significant drawbacks. Pre-tinning requirements are too low, with insufficient pretreatment, resulting in poor adhesion of the tin coating to the ribbon. The tinning process takes too long, resulting in an excessively thick tin layer. The ribbon also suffers from poor stability during rewinding, which can lead to wear and oxidation, affecting surface quality. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A photovoltaic ribbon tinning device with a winding and anti-wear function, comprising: a fixed chassis, an operating table fixedly mounted on one side of the outer surface of the fixed chassis, a flip cover rotatably mounted on the top of the fixed chassis, and a cooling fan fixedly mounted on the interior of the fixed chassis away from the operating table;

[0005] A loading rack group, which is used for anti-deviation conveying of photovoltaic welding ribbons. The loading rack group is fixedly installed inside the fixed chassis, and a motor is fixedly installed on the outer surface of the loading rack group;

[0006] A tin coating assembly is used to evenly coat the surface of the photovoltaic ribbon with tin material. The tin coating assembly is fixedly mounted inside the loading rack assembly, and the tin coating assembly is mounted above the interior of the fixed chassis through the loading rack assembly;

[0007] A protective component is used for guiding and winding the photovoltaic welding ribbon after tinning. The protective component is fixedly mounted on the outer surface of the fixed chassis away from the operating table.

[0008] Preferably, the loading rack group includes an inner support frame, and there are two inner support frames. A reinforcement plate and a mounting rod are fixedly installed between the opposite surfaces of the two inner support frames, and a segmented shaft is rotatably installed between the opposite surfaces of the reinforcement plates. Positioning plates and turntables are fixedly installed on both sides of the outer surface of the inner support frame, and there are two positioning plates and turntables. Extension plates are fixedly installed on the outer surfaces of the two positioning plates, and guide rollers are rotatably installed between the extension plates and the opposite surfaces of the inner support frames. When the staff is tinning the surface of the photovoltaic welding ribbon, the staff will install multiple sets of photovoltaic welding ribbon sleeves on the segmented shaft, and wrap the end of the photovoltaic welding ribbon around the surface of the guide roller to tighten and unfold the photovoltaic welding ribbon and pass it under the tinning component, and then extend it into the protective component along the slot opened on the outside of the fixed chassis, so as to pre-fix the photovoltaic welding ribbon before tinning it. When tinning, the staff starts the motor so that the output end of the motor drives the turntable to rotate. At this time, the turntable drives the guide rollers installed between its opposite surfaces to rotate, so that the guide rollers rotate in the fixed chassis and the photovoltaic welding ribbon wrapped on the segmented shaft moves with the rotation direction of the guide rollers. At this time, multiple sets of guide rollers are affected by the displacement driven by photovoltaic welding and rotate to tighten and guide the photovoltaic welding ribbon, so that the photovoltaic welding ribbon is smoother when tinning, so as to improve the adhesion of the tin material when applying.

[0009] Preferably, the turntable is fixedly connected to the output end of the motor, the inner support frame is fixedly installed inside the fixed chassis, and the guide roller is fixedly installed between the opposite surfaces of the turntable.

[0010] Preferably, the guide roller includes six rotating shafts, which are triangularly distributed between the opposing surfaces of the extension plate, the inner support frame, and the turntable. Segmented ring columns are sleeved on the outer surface of the rotating shaft, and guide rings are fixedly installed between adjacent surfaces of the segmented ring columns. The guide rings are frictionally adapted to the photovoltaic welding ribbon, and limit rings are fixedly installed on both sides of the outer surface of the segmented ring columns. A staff member places the photovoltaic welding ribbon at the pulling position within the guide ring, and then starts the motor, so that the motor output drives the turntable to rotate within the inner support frame. At this time, the rotating shaft installed in the turntable rotates, and the segmented ring columns provided on both sides of the guide ring limit the photovoltaic welding ribbon to prevent deviation during transportation.

[0011] Preferably, the tin coating assembly includes a positioning frame, which is fixedly mounted on the bottom of the mounting rod, a cross frame fixedly mounted inside the positioning frame, mounting blocks fixedly mounted on both sides of the outer surface of the cross frame, an applicator fixedly mounted on one side of the outer surface of the mounting block, a square groove is provided inside the applicator, a tin spraying member is fixedly mounted in the middle of the outer surface of the cross frame, and the tin spraying member passes through the interior of the applicator through the square groove. After the photovoltaic welding ribbon moves under the tin spraying member, the tin spraying member sprays tin material on the photovoltaic welding ribbon. The photovoltaic welding ribbon moves under the applicator as the turntable rotates, and generates friction with the applicator. The sprayed tin material is evenly spread by the applicator. There are three tin spraying members, corresponding to the photovoltaic welding ribbon coils mounted on the segmented shaft, which can simultaneously perform tin coating processing on multiple groups of photovoltaic welding ribbons to speed up the tin coating efficiency.

[0012] Preferably, the tin-spraying component includes a sleeve, the outer surface of which is fixedly provided with a liquid storage cavity, the interior of which is fixedly provided with a liquid guide tube, three of which are provided with spray tubes fixedly provided at the bottoms of the three liquid guide tubes. The staff puts the tin material into the liquid storage cavity, and when the photovoltaic welding ribbon passes under the spray tube, the tin material in the liquid guide tube is sprayed out along the spray tube. At this time, the tinned photovoltaic welding ribbon moves at a uniform speed under the smearing plate in a moving state, and the smearing plate evenly spreads the tin material sprayed on the photovoltaic welding ribbon to avoid the photovoltaic welding ribbon being tinned for too long and resulting in an excessively thick tin layer. During the tinning process, the cooling fan installed inside the fixed chassis is in operation, so that the photovoltaic welding ribbon with the tinned layer on the surface is quickly cooled in the feeding rack, and the protective atmosphere is used to prevent the tinned layer from being severely oxidized, thereby improving the tinning effect.

[0013] Preferably, the sleeve is fixedly mounted in the middle of the outer surface of the cross frame, the liquid storage cavity runs through the interior of the smear member, and the spray tube is adapted to the photovoltaic welding strip.

[0014] Preferably, the smear member includes an external frame, which is fixedly mounted on the outer surface of the mounting block. Two external frames are provided, and a hydraulic press is fixedly mounted inside the two external frames. A connecting seat is fixedly mounted on the bottom of the hydraulic press, and an smear plate is fixedly mounted on the bottom of the connecting seat. The smear plate is frictionally adapted to the photovoltaic welding strip.

[0015] Preferably, the protective component includes a connecting plate, which is fixedly installed on the outside of the fixed chassis. Two connecting plates are provided, and the outer surfaces of the two connecting plates are fixedly installed with a splint. The inside of the splint is fixedly installed with a support frame, the top of the support frame is fixedly installed with a fixed block, and the guide frame is fixedly installed between the opposite surfaces of the fixed blocks.

[0016] Preferably, the guide frame includes a top plate, which is fixedly mounted between opposite surfaces of the fixed block, with guide grooves provided on both sides of the bottom of the top plate, a center frame fixedly mounted in the middle of the top of the top plate, and protective plates fixedly mounted on both sides of the bottom of the center frame. After the tinned layer on the surface of the photovoltaic ribbon cools, the photovoltaic ribbon passes through the side of the fixed chassis, penetrates the top plate, and passes through the guide grooves on both sides. Since the protective component is connected to the guide-out reeling device, the photovoltaic ribbon delivered from the guide frame is wound above the reeling device. The inner wall of the guide groove in the top plate is set to an arc shape to reduce friction with the photovoltaic ribbon when the photovoltaic ribbon is reeled, so as to improve the stability of the photovoltaic ribbon when it is reeled, and avoid surface wear affecting the quality when the photovoltaic ribbon is reeled. Moreover, the top plate and the protective plate are wrapped around the outside of the photovoltaic ribbon to reduce the contact area between the photovoltaic ribbon and the air, and prevent it from being easily oxidized after the tin coating treatment.

[0017] The present invention provides a photovoltaic ribbon tinning device with a winding and anti-wear function. It has the following beneficial effects:

[0018] 1. The photovoltaic welding ribbon tinning equipment with a winding and anti-wear function is that when the staff is tinning the surface of the photovoltaic welding ribbon, the staff will install multiple sets of photovoltaic welding ribbons on the segmented shaft, and wrap the ends of the photovoltaic welding ribbons around the surface of the guide rollers to tighten and unfold the photovoltaic welding ribbons and pass them under the tinning component, and then extend them into the protective component along the slots opened on the outside of the fixed chassis, so as to pre-fix the photovoltaic welding ribbons before tinning. When tinning, the staff starts the motor so that the output end of the motor drives the turntable to rotate. At this time, the turntable drives the guide rollers installed between its opposite surfaces to rotate, so that the guide rollers rotate in the fixed chassis and the photovoltaic welding ribbons wrapped on the segmented shafts move along the rotation direction of the guide rollers. At this time, multiple sets of guide rollers are affected by the displacement driven by photovoltaic welding and rotate to tighten and guide the photovoltaic welding ribbons, so that the photovoltaic welding ribbons are smoother when tinning, so as to improve the adhesion of the tin material when applying.

[0019] 2. The photovoltaic welding ribbon tinning equipment with the anti-wear function of winding is that the staff places the pulled photovoltaic welding ribbon in the guide ring, and then the staff starts the motor so that the output end of the motor drives the turntable to rotate in the inner support frame. At this time, the rotating shaft installed in the turntable rotates. At this time, the segmented ring columns set on both sides of the guide ring limit the photovoltaic welding ribbon to prevent the photovoltaic welding ribbon from offset during transportation.

[0020] 3. The photovoltaic welding ribbon tin coating equipment with the anti-wear function of winding up, after the photovoltaic welding ribbon moves to the bottom of the tin spraying part, the tin spraying part sprays the tin material on the photovoltaic welding ribbon, and the photovoltaic welding ribbon moves toward the bottom of the smearing part as the turntable rotates, and generates friction with the smearing part, and the sprayed tin material is evenly spread by the smearing part. There are three tin spraying parts, which correspond to the photovoltaic welding ribbon rolls installed on the segmented shaft. Multiple groups of photovoltaic welding ribbons can be tinned at the same time to speed up the tin coating efficiency.

[0021] 4. The photovoltaic welding ribbon tinning equipment with the function of winding and anti-wear is equipped with a staff to fill the tin material into the liquid storage chamber. When the photovoltaic welding ribbon passes under the spray tube, the tin material in the liquid guide tube is sprayed out along the spray tube. At this time, the tinned photovoltaic welding ribbon moves at a uniform speed under the coating plate in a moving state. The coating plate evenly spreads the tin material sprayed on the photovoltaic welding ribbon to avoid the photovoltaic welding ribbon tinning time being too long and resulting in an excessively thick tin layer. During the tinning process, the cooling fan installed inside the fixed chassis is in operation, so that the photovoltaic welding ribbon with a tinned layer on the surface is quickly cooled in the material rack, and the protective atmosphere is used to avoid severe oxidation of the tinned layer, thereby improving the tinning effect.

[0022] 5. The photovoltaic welding ribbon tinning equipment with the anti-wear function of winding the photovoltaic welding ribbon, after the tin plating layer on the surface of the photovoltaic welding ribbon is cooled, the photovoltaic welding ribbon passes through the side of the fixed chassis, penetrates the top plate, and passes through the guide grooves on both sides. Since the protective component is connected to the lead-out and winding device, the photovoltaic welding ribbon delivered from the lead-out frame is wound above the winding device, and the inner wall of the guide groove in the top plate is set to be an arc shape to reduce the friction with the photovoltaic welding ribbon when the photovoltaic welding ribbon is wound, so as to improve the stability of the photovoltaic welding ribbon when it is wound, and avoid surface wear of the photovoltaic welding ribbon when it is wound to affect the quality, and the top plate and the protective plate covering the outside of the photovoltaic welding ribbon can reduce the contact area of the photovoltaic ribbon with the air, and prevent it from being easily oxidized after tin coating.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0035] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: a photovoltaic welding ribbon tinning device with a winding and anti-wear function, comprising: a fixed chassis 5, an operating table 1 is fixedly installed on one side of the outer surface of the fixed chassis 5, a flip cover 2 is rotatably installed on the top of the fixed chassis 5, and a cooling fan 7 is fixedly installed on the inside of the fixed chassis 5 away from the operating table 1;

[0036] A loading rack group 4 is used for anti-deviation conveying of photovoltaic welding ribbons. The loading rack group 4 is fixedly installed inside a fixed chassis 5, and a motor 6 is fixedly installed on the outer surface of the loading rack group 4;

[0037] A tin coating component 8 is used to evenly coat the surface of the photovoltaic ribbon with tin material. The tin coating component 8 is fixedly mounted inside the loading rack group 4. The tin coating component 8 is mounted above the interior of the fixed chassis 5 through the loading rack group 4.

[0038] The protective component 3 is used for guiding and winding the photovoltaic welding ribbon after tinning. The protective component 3 is fixedly mounted on the outer surface of the fixed chassis 5 away from the operating table 1.

[0039] The loading rack group 4 includes an inner support frame 41, and there are two inner support frames 41. A reinforcement plate 43 and a mounting rod 48 are fixedly installed between the opposite surfaces of the two inner support frames 41. A segmented shaft 44 is rotatably installed between the opposite surfaces of the reinforcement plate 43. Positioning plates 47 and turntables 42 are fixedly installed on both sides of the outer surface of the inner support frame 41. There are two positioning plates 47 and two turntables 42. Extension plates 45 are fixedly installed on the outer surfaces of the two positioning plates 47. Guide rollers 46 are rotatably installed between the extension plates 45 and the opposite surfaces of the inner support frames 41. When the staff is tinning the surface of the photovoltaic welding ribbon, the staff will install multiple sets of photovoltaic welding ribbons on the segmented shaft 44, and wrap the end of the photovoltaic welding ribbon around the surface of the guide roller 46 to tighten and unfold the photovoltaic welding ribbon and pass it under the tinning component 8, and then extend it along the slot opened on the outside of the fixed chassis 5 into the protective component 3, so as to pre-fix the photovoltaic welding ribbon before tinning it. When tinning, the staff starts the motor 6 so that the output end of the motor 6 drives the turntable 42 to rotate. At this time, the turntable 42 drives the guide roller 46 installed between its opposite surfaces to rotate, so that the guide roller 46 rotates in the fixed chassis 5 and the photovoltaic welding ribbon wrapped on the segmented shaft 44 moves along the rotation direction of the guide roller 46. At this time, multiple sets of guide rollers 46 are affected by the displacement driven by photovoltaic welding and rotate to tighten and guide the photovoltaic welding ribbon, so that the photovoltaic welding ribbon is smoother when tinning, so as to improve the adhesion of the tin material when applying.

[0040] The turntable 42 is fixedly connected to the output end of the motor 6 , the inner support frame 41 is fixedly installed inside the fixed chassis 5 , and the guide rollers 46 are fixedly installed between opposite surfaces of the turntable 42 .

[0041] The guide roller 46 includes six rotating shafts 462, distributed in a triangular pattern between the opposing surfaces of the extension plate 45, the inner support frame 41, and the turntable 42. Segmented ring columns 461 are sleeved on the outer surfaces of the rotating shafts 462. Guide rings 464 are fixedly mounted between adjacent surfaces of the segmented ring columns 461, frictionally engaging the photovoltaic ribbon. Limiting rings 463 are fixedly mounted on either side of the outer surface of the segmented ring columns 461. A worker places the photovoltaic ribbon within the guide rings 464 and then activates the motor 6, causing the output end of the motor 6 to drive the turntable 42 to rotate within the inner support frame 41. This causes the rotating shafts 462 mounted within the turntable 42 to rotate, and the segmented ring columns 461 on either side of the guide rings 464 limit the photovoltaic ribbon to prevent it from shifting during transport.

[0042] The second embodiment, based on the first embodiment, see Figures 6 to 8 As shown, the tin coating assembly 8 includes a positioning frame 81, which is fixedly mounted on the bottom of the mounting rod 48. A cross frame 84 is fixedly mounted inside the positioning frame 81. Mounting blocks 83 are fixedly mounted on both sides of the outer surface of the cross frame 84. A smear member 82 is fixedly mounted on one side of the outer surface of the mounting block 83. The smear member 82 has a square groove 85 formed inside. A tin spray member 86 is fixedly mounted in the middle of the outer surface of the cross frame 84. The tin spray member 86 passes through the inner portion of the smear member 82 through the square groove 85. After the photovoltaic ribbon moves below the tin spray member 86, the tin spray member 86 sprays tin material onto the photovoltaic ribbon. As the turntable 42 rotates, the photovoltaic ribbon moves below the smear member 82 and generates friction with the smear member 82. The tin material is evenly spread by the smear member 82. Three tin spray members 86 are provided, corresponding to the photovoltaic ribbon rolls mounted on the segmented shaft 44. Multiple groups of photovoltaic ribbons can be tinned simultaneously to speed up the tin coating efficiency.

[0043] The tin-spraying member 86 includes a housing 862, the outer surface of which is fixedly mounted a liquid reservoir 861. Within the housing 861 are fixedly mounted three liquid guide tubes 863, each of which has a spray tube 864 fixedly mounted at its bottom. A worker places tin material in the liquid reservoir 861. As the photovoltaic ribbon passes under the spray tube 864, the tin material in the liquid guide tube 863 is sprayed out along the spray tube 864. The tinned photovoltaic ribbon then moves at a constant speed below the smear plate 823. The smear plate 823 evenly spreads the tin material on the ribbon, preventing the ribbon from being tinned for too long and resulting in an excessively thick tin layer. During the tinning process, the cooling fan 7 installed within the fixed chassis 5 is in operation, rapidly cooling the tinned photovoltaic ribbon within the feed rack. This protective atmosphere prevents severe oxidation of the tin layer, thereby improving the tinning effect.

[0044] The sleeve frame 862 is fixedly installed in the middle of the outer surface of the cross frame 84, the liquid storage cavity 861 runs through the interior of the smear member 82, and the spray tube 864 is adapted to the photovoltaic welding strip.

[0045] The smear member 82 includes an external frame 824, which is fixedly mounted on the outer surface of the mounting block 83. Two external frames 824 are provided, and a hydraulic press 821 is fixedly mounted inside the two external frames 824. A connecting seat 822 is fixedly mounted on the bottom of the hydraulic press 821, and an smear plate 823 is fixedly mounted on the bottom of the connecting seat 822. The smear plate 823 is frictionally adapted to the photovoltaic welding strip.

[0046] The third embodiment, based on the first and second embodiments, see Figures 9 and 10 As shown, the protective component 3 includes a connecting plate 35, which is fixedly installed on the outside of the fixed chassis 5. Two connecting plates 35 are provided, and the outer surfaces of the two connecting plates 35 are fixedly installed with a splint 32. The inside of the splint 32 is fixedly installed with a support frame 34, and the top of the support frame 34 is fixedly installed with a fixed block 33. The lead-out frame 31 is fixedly installed between the opposite surfaces of the fixed block 33.

[0047] The guide frame 31 includes a top plate 312, which is fixedly installed between the opposite surfaces of the fixed block 33. Guide grooves 311 are provided on both sides of the bottom of the top plate 312. A middle frame 313 is fixedly installed in the middle of the top of the top plate 312, and protective plates 314 are fixedly installed on both sides of the bottom of the middle frame 313. After the tin plating layer on the surface of the photovoltaic welding ribbon cools down, the photovoltaic welding ribbon passes through the side of the fixed chassis 5, penetrates the top plate 312, and passes through the guide grooves 311 on both sides. Since the protective component 3 is connected to the lead-out winding device, the photovoltaic welding ribbon delivered from the lead-out frame 31 is wound above the winding device. The inner wall of the guide groove 311 in the top plate 312 is set to a circular arc shape to reduce the friction with the photovoltaic welding ribbon when the photovoltaic welding ribbon is wound, so as to improve the stability of the photovoltaic welding ribbon when it is wound, and avoid surface wear of the photovoltaic welding ribbon when it is wound to affect the quality. The top plate 312 and the protective plate 314 are wrapped around the outside of the photovoltaic welding ribbon to reduce the contact area between the photovoltaic ribbon and the air, and prevent it from being easily oxidized after tin coating.

[0048] During use, when the staff is tinning the surface of the photovoltaic welding ribbon, they will install multiple sets of photovoltaic welding ribbons on the segmented shaft 44, and wrap the ends of the photovoltaic welding ribbons around the surface of the guide roller 46 to tighten and unfold the photovoltaic welding ribbon and pass it under the tinning component 8, and then extend it into the protective component 3 along the slot opened on the outside of the fixed chassis 5, so as to pre-fix the photovoltaic welding ribbon before tinning it. When tinning, the staff starts the motor 6 so that the output end of the motor 6 drives the turntable 42 to rotate. At this time, the turntable 42 drives the guide roller 46 installed between its opposite surfaces to rotate, so that the guide roller 46 rotates in the fixed chassis 5 and the photovoltaic welding ribbon wrapped on the segmented shaft 44 moves along the rotation direction of the guide roller 46. At this time, multiple sets of guide rollers 46 are affected by the displacement driven by photovoltaic welding and rotate to tighten and guide the photovoltaic welding ribbon, so that the photovoltaic welding ribbon is smoother when tinning, so as to improve the adhesion of the tin material when applying.

[0049] The staff places the pulled photovoltaic welding tape in the guide ring 464, and then the staff starts the motor 6, so that the output end of the motor 6 drives the turntable 42 to rotate in the inner support frame 41. At this time, the rotating shaft 462 installed in the turntable 42 rotates. At this time, the segmented ring columns 461 set on both sides of the guide ring 464 limit the photovoltaic welding tape to prevent the photovoltaic welding tape from being offset during transportation.

[0050] After the photovoltaic welding ribbon moves to the bottom of the tin-spraying part 86, the tin-spraying part 86 sprays tin material on the photovoltaic welding ribbon. The photovoltaic welding ribbon moves to the bottom of the smearing part 82 as the turntable 42 rotates, and generates friction with the smearing part 82. The sprayed tin material is evenly spread through the smearing part 82. There are three tin-spraying parts 86, which correspond to the photovoltaic welding ribbon rolls installed on the segmented shaft 44. They can simultaneously perform tin coating on multiple groups of photovoltaic welding ribbons to speed up the tin coating efficiency.

[0051] The staff puts the tin material into the liquid storage chamber 861. When the photovoltaic welding ribbon passes under the spray tube 864, the tin material in the liquid guide tube 863 is sprayed out along the spray tube 864. At this time, the tinned photovoltaic welding ribbon moves at a constant speed under the smear plate 823 in a moving state. The smear plate 823 evenly spreads the tin material sprayed on the photovoltaic welding ribbon to avoid the photovoltaic welding ribbon tinning time being too long and resulting in an excessively thick tin layer. During the tinning process, the cooling fan 7 installed inside the fixed chassis 5 is in operation, so that the photovoltaic welding ribbon with a tinned layer on the surface is quickly cooled in the material transfer rack, and the protective atmosphere is used to prevent the tinned layer from being severely oxidized, thereby improving the tinning effect.

[0052] After the tin plating layer on the surface of the photovoltaic welding ribbon cools down, the photovoltaic welding ribbon passes through the side of the fixed chassis 5, penetrates the top plate 312, and passes through the guide grooves 311 on both sides. Since the protective component 3 is connected to the lead-out winding device, the photovoltaic welding ribbon delivered from the lead-out frame 31 is wound above the winding device. The inner wall of the guide groove 311 in the top plate 312 is set to a circular arc shape to reduce the friction with the photovoltaic welding ribbon when the photovoltaic welding ribbon is wound, so as to improve the stability of the photovoltaic welding ribbon when it is wound, and avoid surface wear of the photovoltaic welding ribbon when it is wound to affect the quality. The top plate 312 and the protective plate 314 are wrapped around the outside of the photovoltaic welding ribbon to reduce the contact area between the photovoltaic ribbon and the air, and prevent it from being easily oxidized after tin coating.
