Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic production equipment, and in particular relates to a copper strip slitting device for making photovoltaic welding strip bus bars. Background Art

[0002] PV ribbon busbars are an important component in solar photovoltaic systems, used to connect the current between solar panels and transmit the current from the panels to the photovoltaic inverter or the grid. PV ribbon busbars are usually made of copper, which has high electrical conductivity and good conductive properties to ensure minimal energy loss.

[0003] PV ribbon busbars concentrate the current from solar panels to a main current collection point and distribute it to battery packs, inverters or the grid. In general, PV ribbon busbars play a key role in connection and current distribution in solar photovoltaic systems, which has an important impact on the performance and efficiency of the system.

[0004] In the manufacturing process of photovoltaic welding ribbon busbars, the copper strips are generally slit into required specifications, and then the slit copper strips are rolled up, and then the rolled copper strips are tinned at high speed. After the high-speed tinning is completed, the copper strips are rolled up again, and the busbars are manufactured. Therefore, the slit copper strips need to be tinned. In order to achieve a good tinning effect, the surface of the copper strips needs to be polished and trimmed after slitting to remove dust, burrs and other impurities on the surface of the copper strips. Traditional copper strip slitting machines do not have a polishing function, and require a special surface treatment process before tinning, which affects the improvement of processing efficiency.

[0005] Photovoltaic welding ribbon busbars have a variety of different widths, so when slitting copper strips, they need to be slit into copper strips of different widths. Traditional slitting equipment needs to adjust the slitting width, not only does it need to adjust the distance between the cutters, but it also needs to replace multiple sets of limit rollers on the production line. Adjustment is very inconvenient and is not conducive to improving processing efficiency. Summary of the invention

[0062] Since the conveying roller 34 is rotatably connected to the strip sorting bracket 14, a circular slide rail is provided on the edge of the grinding wheel disc 331, and the gripping block 332 is slidably connected to the circular slide rail, the conveying roller 34 can drive the copper belt to move, while the grinding wheel disc 331 does not move, so that the side of the grinding wheel disc 331 can grind the side of the copper belt, and the gripping block 332 is slidably connected to the circular slide rail, so that the side of the grinding wheel disc 331 can grind the side of the copper belt. When the friction is too large, the grinding wheel disc 331 can rotate to prevent the copper belt from getting stuck or bending due to excessive friction between the grinding wheel disc 331 when grinding the side of the copper belt, thereby ensuring the quality of the copper belt slitting.

[0063] like Fig.11 - Fig.12 As shown, the grinding mechanism 4 includes a slide plate 41, a pressure plate 42, a grinding head 43 and a grinding motor 44. A grinding bracket 15 is fixedly arranged above the conveyor belt 5 on the base 1. The slide plate 41 is slidably connected to the grinding bracket 15. A pressure plate 42 is arranged above the slide plate 41. Second adjusting bolts 421 are threadedly connected at both ends of the pressure plate 42. The second adjusting bolts 421 penetrate the slide plate 41, and the second adjusting bolts 421 are threadedly connected to the slide plate 41. A plurality of grinding heads 43 are arranged on the slide plate 41. The grinding heads 43 penetrate the slide plate 41, and the grinding heads 43 are slidably connected to the slide plate 41. A plurality of grinding motors 44 are correspondingly fixedly connected to the bottom of the pressure plate 42. The top of the grinding head 43 is fixedly connected to the rotating shaft of the grinding motor 44. A second adjusting spring 441 is fixedly connected to the bottom of the grinding motor 44. The second adjusting spring 441 is sleeved outside the grinding head 43, and the bottom of the second adjusting spring 441 is fixedly connected to the top of the slide plate 41.

[0064] In this embodiment, the grinding motor 44 can drive the grinding head 43 to rotate and grind the upper surface of the copper belt, and the vertical height between the pressure plate 42 and the slide plate 41 can be adjusted by screwing the second adjusting bolt 421, that is, the vertical height between the grinding head 43 and the conveyor belt 5 can be adjusted, and the second adjusting spring 441 can buffer the grinding head 43 to prevent the grinding head 43 from exerting too much pressure on the copper belt on the conveyor belt 5, causing the copper belt to get stuck during grinding, and sandpaper can be set on the conveyor belt 5 so that the conveyor belt 5 grinds the bottom surface of the copper belt, and the slide plate 41 can slide on the grinding bracket 15, and the grinding mechanism 4 can be pushed to slide horizontally left and right, so that the copper belt on the conveyor belt 5 can be better and more comprehensively ground.

[0065] like Figure 1 as well as Fig.12 As shown, a first groove 11 is provided at the rear side of the feed roller 6 , a second groove 12 is provided at the front side of the winding roller 7 , and a driving motor 141 is fixedly connected to one side of the strip arrangement bracket 14 .

[0066] In this embodiment, a driving motor 141 is fixedly connected to one side of the strip sorting bracket 14, and the driving motor 141 can drive the conveying roller 34 to rotate. The setting of the first groove 11 and the second groove 12 can allow the copper belt to sink into the first groove 11 or the second groove 12 during the conveying process, and the flatness and tightness of the copper belt during conveying and the bending radius of the copper belt can be adjusted to prevent the copper belt from being deformed or damaged during transportation. A strip sorting mechanism 3 can be set between the cutting mechanism 2 and the grinding mechanism 4, and multiple strip sorting mechanisms can be set on the rear side of the grinding mechanism 4, which can not only limit the cut copper belt well and facilitate the winding of the cut copper belt, but also grind the side of the copper belt multiple times, effectively improving the grinding effect.

[0067] Working principle:

[0068] When the copper strip is cut, the copper strip is placed on the feeding roller 6. After the copper strip passes through the cutting mechanism 2, the strip sorting mechanism 3 and the grinding mechanism 4, the cut copper strip is rolled up by the winding roller 7 to complete the cutting of the copper strip.

[0069] The grinding motor 44 can drive the grinding head 43 to rotate and grind the upper surface of the copper belt, and the vertical height between the pressure plate 42 and the slide plate 41 can be adjusted by screwing the second adjusting bolt 421, that is, the vertical height between the grinding head 43 and the conveyor belt 5 can be adjusted, and the second adjusting spring 441 can buffer the grinding head 43 to prevent the grinding head 43 from exerting too much pressure on the copper belt on the conveyor belt 5, causing the copper belt to get stuck during grinding, and sandpaper can be set on the conveyor belt 5, so that the conveyor belt 5 grinds the bottom surface of the copper belt, and the slide plate 41 can slide on the grinding bracket 15, and the grinding mechanism 4 can slide horizontally left and right by pushing the slide plate 41, so that the copper belt on the conveyor belt 5 can be better and more comprehensively ground;

[0070] When it is necessary to cut copper strips of different widths, the first electric push rod 211 is started, and the first electric push rod 211 can push the first sliding frame 22 to slide horizontally forward and backward on the first limiting top plate 21, and the first sliding frame 22 will drive the tool 23 to slide horizontally forward and backward at the same time. At this time, the first limiting block 231 on the tool 23 will slide horizontally forward and backward in the first inclined groove 212 at the same time, and the first limiting block 231 sliding horizontally forward and backward in the first inclined groove 212 will change the distance between adjacent first limiting blocks 231, thereby driving the tool 23 to slide horizontally left and right in the first sliding frame 22, that is, adjusting the distance between adjacent tools 23, so as to adjust the width of the cut copper strip;

[0071] At the same time, the second electric push rod 311 is started, and the second electric push rod 311 can drive the second sliding frame 32 to slide horizontally forward and backward on the second limiting top plate 31, thereby driving the sliding block 334 to slide horizontally forward and backward. The sliding block 334 can drive the second limiting block 335 to slide horizontally forward and backward in the second inclined groove 312. The second limiting block 335 can slide horizontally forward and backward in the second inclined groove 312, and the spacing between adjacent second limiting blocks 335 can be changed, thereby driving the sliding block 334 to slide horizontally left and right in the second sliding frame 32, that is, changing the spacing between adjacent sliding blocks 334. The sliding block 334 can drive the grinding wheel 331 to slide horizontally left and right in the second sliding frame 32, so as to adjust the spacing between adjacent grinding wheel discs 331. There is no need to replace the tool 23 and multiple sets of limiting rollers to meet the needs of cutting copper strips of different widths, which can effectively improve production efficiency.

[0072] The driving motor 141 can drive the conveying roller 34 to rotate, and the conveying roller 34 rotates to drive the copper belt to move, while the grinding wheel 331 does not move, so that the side of the grinding wheel 331 can grind the side of the copper belt, and the gripping block 332 is slidably connected with the circular slide rail, so that the side of the grinding wheel 331 can grind the side of the copper belt. When the friction is too large, the grinding wheel 331 can rotate to prevent the copper belt from getting stuck or bent due to excessive friction between the grinding wheel 331 when grinding the side of the copper belt, thereby ensuring the quality of the copper belt slitting;

[0073] The arrangement of multiple strip-sorting mechanisms 3 allows the cut copper strip to pass through the strip-sorting mechanisms 3 multiple times, which not only limits the cut copper strip multiple times to facilitate the winding of the cut copper strip, but also allows the side of the copper strip to be polished multiple times. The spacing between the grinding wheels 331 on the multiple strip-sorting mechanisms 3 can also be fine-tuned, so that the spacing between the grinding wheels 331 through which the copper strip passes becomes smaller and smaller, and the copper strip can be polished more finely, effectively improving the polishing effect.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
