Technical Field

[0001] The utility model belongs to the technical field of optical film processing, and in particular relates to a striping structure for a reflective film in a gap between photovoltaic cells. Background Art

[0002] Solar cells (photovoltaic cells) are photoelectric semiconductor sheets that use sunlight to generate electricity directly. They are also called "solar chips" or "photovoltaic cells". As long as they are illuminated under certain illumination conditions, they can instantly output voltage and generate current in a circuit.

[0003] When photovoltaic panels are manufactured, a gap is left between two adjacent groups of photovoltaic cells to avoid short circuits. Therefore, in actual photovoltaic applications, some light will pass through the gap, resulting in a decrease in the power per unit area of ​​the photovoltaic cell or the photovoltaic conversion efficiency (e.g. Figure 8 shown).

[0004] In order to improve the utilization rate of solar energy, a reflective film (such as Fig. 9 As shown in the figure, the light that passes through the gap is reflected back to the photovoltaic cell through the reflective film, thereby improving the light utilization rate per unit area and thus increasing the power of the component.

[0005] When the reflective film is produced and shipped out of the factory, the sheet-like reflective film needs to be cut into strips of specified width as needed, and then the strip-like reflective film after slitting is rolled into a roll to facilitate subsequent transfer and use.

[0042] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0043] like Figure 1-4The figure shows a schematic diagram of the striping structure for the photovoltaic cell gap reflective film of the utility model, which is usually used to cut and strip the reflective film, and then wind the reflective film after striping into a roll to facilitate subsequent transfer and transportation. The striping structure includes a support plate 1, a discharge roller 2, a tensioning assembly 3, a striping assembly 4, a conveying assembly 5 and a material shifting assembly 6. There are two groups of support plates 1, which are vertically fixed on the working machine by welding, and the two groups of support plates 1 are arranged at intervals. The discharge roller 2, the tensioning assembly 3, the striping assembly 4, the conveying assembly 5 and the material shifting assembly 6 are all installed on the support plate 1.

[0044] The discharge roller 2 is rotatably installed between the two groups of support plates 1, and the reflective film material tray to be stripped is sleeved on the discharge roller 2. Under the rotation of the conveying component 5, the discharge roller 2 is pulled to rotate, and then the discharge of the reflective film is completed.

[0045] The tensioning assembly 3 is disposed between the two sets of support plates 1 and is used to tension the reflective film after unwinding to prevent the reflective film from being loosened and affecting the stripping of the stripping assembly 4. Figure 4 As shown, the tensioning assembly 3 includes a feeding roller 301, a tensioning main roller 302, a tensioning auxiliary roller 303, a carrier plate 304, a pressing cylinder 305, a pressing plate 306 and a pressure strip 307. The feeding roller 301 is rotatably installed between the two groups of support plates 1, and the reflective film after unloading bypasses the feeding roller 301 and rests on the carrier plate 304. The feeding roller 301 can play a transitional role for the reflective film, preventing the reflective film from directly resting on the carrier plate 304 and contacting the side of the carrier plate 304, resulting in wear and breakage of the reflective film.

[0046] The tensioning main roller 302 and the tensioning auxiliary roller 303 are rotatably mounted between the two sets of support plates 1 and are located on the side of the feeding roller 301 away from the unwinding roller 2, and are used to tension the reflective film to prevent the reflective film from loosening and affecting the striping effect. Figure 1 As shown, there are two groups of tensioning main rollers 302, which are rotatably mounted on the top of the two groups of support plates 1 and are spaced apart. The tensioning auxiliary rollers 303 are rotatably mounted between the two groups of support plates 1 and close to the bottom of the support plates 1. The tensioning auxiliary rollers 303 are located between the two groups of tensioning main rollers 302. The reflective film after unloading first bypasses the first group of tensioning main rollers 302, then bypasses the tensioning auxiliary rollers 303 from the bottom, and finally bypasses the other group of tensioning main rollers 302 from the top.

[0047] In this embodiment, both ends of the tensioning auxiliary roller 303 pass through the waist-shaped holes on the support plate 1 and are connected to the lifting cylinder on the outside of the support plate 1. The tensioning auxiliary roller 303 is driven downward by the lifting cylinder to adjust the tensioning auxiliary roller 303, thereby playing the role of tensioning the reflective film (the lifting cylinder is not shown in the figure).

[0048] The carrier plate 304 is fixed between the two sets of support plates 1 and is tilted. The reflective film that passes the feeding roller 301 is placed on the carrier plate 304 and then wrapped around the tensioning main roller 302. A pressing cylinder 305 is fixed at the bottom of the carrier plate 304. The pressing plate 306 is connected to the guide rod of the pressing cylinder 305, and the pressing plate 306 is driven to move by the pressing cylinder 305.

[0049] The pressing plate 306 is always parallel to the carrier plate 304 during the movement. A rubber pressure strip 307 is fixed to the side of the pressing plate 306 close to the carrier plate 304. After the reflective film after stripping is wound into a tube by the rubber roller in front, it is necessary to cut off the reflective film after stripping and replace it with a new rubber tube. At this time, the reflective film is easy to spread out at the discharge roller 2. Therefore, the pressing plate 306 is driven down by the pressing cylinder 305, and the reflective film is pressed by the pressure strip 307.

[0050] The rubber pressure strip 307 has two functions. First, it can better press the reflective film by utilizing the deformable characteristic of the rubber material. Second, it can avoid scratching the surface of the reflective film when pressing the reflective film.

[0051] The stripping assembly 4 is fixed on the support plate 1 and is used to strip the reflective film after tensioning. Figure 6 As shown, the slitting assembly 4 includes a slitting plate 401, a slot 402, a fixing plate 403, a first regulating cylinder 404, an upper slide plate 405, an upper slide groove 406, a lower slide plate 407, a lower slide groove 408, an upper slitting roller 409, a lower slitting roller 410, a cutting knife 411 and a knife groove 412. The slitting plate 401 is vertically fixed on the supporting plate 1, and is used to install the upper slitting roller 409 and the lower slitting roller 410.

[0052] The slitting plate 401 is provided with a vertically arranged slot 402, and the upper slide plate 405 and the lower slide plate 407 are clamped in the slot 402. The outer side of the upper slide plate 405 is provided with an upper slide groove 406 that is slidably connected with the slitting plate 401, and the two sides of the lower slide plate 407 are provided with lower slide grooves 408 that are slidably connected with the slitting plate 401. By providing the upper slide groove 406 and the lower slide groove 408, on the one hand, it is convenient to replace the upper slitting roller 409 and the lower slitting roller 410, and on the other hand, when the reflective film is slid, the upper slitting roller 409 and the lower slitting roller 410 can be prevented from shaking, thereby affecting the slitting effect.

[0053] The fixed plate 403 is fixed to the top of the slitting plate 401 by screw fastening. The first adjusting cylinder 404 is fixed on the fixed plate 403 and is connected to the upper slide plate 405. It is used to drive the upper slide plate 405 to rise and fall in the slot 402, thereby adjusting the distance between the upper slitting roller 409 and the lower slitting roller 410 to achieve slitting of reflective films of different thicknesses.

[0054] The upper slitting roller 409 is rotatably installed between the upper slide plates 405 , and the lower slitting roller 410 is rotatably installed between the lower slide plates 407 . The tensioned reflective film passes between the upper slitting roller 409 and the lower slitting roller 410 .

[0055] like Figure 6 As shown, the cutter 411 is sleeved on the upper slitting roller 409 and arranged at intervals, and the knife groove 412 is opened on the outer peripheral surface of the lower slitting roller 410 and is used in conjunction with the cutter 411. The reflective film after tensioning runs between the upper slitting roller 409 and the lower slitting roller 410. When the cutter 411 is slitting, the cutter 411 will fall into the knife groove 412 of the lower slitting roller 410, thereby cutting the reflective film. At this time, the reflective film has a certain wrap angle in the knife groove 412, and it is not easy to drift. The existence of the knife groove 412 also prevents the cutter 411 from cutting the lower slitting roller 410, thereby extending the service life of the equipment and improving the efficiency of slitting.

[0056] The conveying assembly 5 is fixed on the supporting plate 1 and is used to pull the cut reflective film forward. Figure 5 As shown, the conveying assembly 5 includes a slide rail 501, a slider 502, a lifting plate 503, a vertical plate 504, a second adjusting cylinder 505, a supporting roller 506 and a pressing roller 507. The slide rail 501 is vertically fixed to the inner side of the support plate 1 by screw fastening, and the slider 502 is slidably mounted on the slide rail 501. The lifting plate 503 is fixed on the slider 502 and connected to the second adjusting cylinder 505. The lifting plate 503 is driven to rise and fall by the second adjusting cylinder 505, thereby adjusting the distance between the supporting roller 506 and the pressing roller 507 to meet the clamping and twitching of reflective films of different thicknesses.

[0057] The support roller 506 is rotatably installed between the two groups of support plates 1, and the pressure roller 507 is rotatably installed between the two groups of lifting plates 503. The reflective film after stripping is located between the support roller 506 and the pressure roller 507, and is pulled forward under the squeezing and rotation of the two.

[0058] The material shifting assembly 6 is fixed on the support plate 1 and is located on the other side of the conveying assembly 5, and is used to shift the reflective film after slitting to facilitate the winding of the reflective film. Figure 7 As shown, the material diverting assembly 6 includes a material diverting frame 601, a material blocking roller 602, an extension plate 603, a fixing rod 604 and a material diverting mechanism. The material diverting frame 601 is fixed to the side of the support plate 1, and there are two groups of material blocking rollers 602, which are rotatably mounted on the material diverting frame 601 and are arranged at intervals in the vertical direction. The multiple groups of narrow reflective films after stripping are located between the upper and lower groups of material blocking rollers 602. Under the action of the material blocking rollers 602, the narrow reflective films are prevented from being entangled.

[0059] The extension plate 603 is integrally connected to the side of the material-diverting frame 601 away from the support plate 1, and the fixing rod 604 is fixed between the two groups of extension plates 603 for installing the material-diverting mechanism. There are multiple groups of material-diverting mechanisms, which are adjustably sleeved on the fixing rod 604. A slit narrow reflective film is passed between each two adjacent groups of material-diverting mechanisms, and the multiple groups of narrow reflective films are separated by the multiple groups of material-diverting mechanisms. Then the narrow reflective film is wound into a roll by a winding roller.

[0060] Each set of material-dispensing mechanisms includes a collar 605, a bearing portion 606, a column 607, a sleeve 608 and a baffle 609. The collar 605 is sleeved on the fixing rod 604 and its position can be adjusted along the axis direction of the fixing rod 604 (a through hole is provided on the collar 605, and a plurality of fixing holes are provided on the fixing rod 604 at equal intervals. After adjusting the position of the collar 605, the fastening screw is passed through the through hole and fixed in the fixing hole).

[0061] A horizontal bearing portion 606 is provided at the top of the collar 605 to facilitate fixing of the column 607. The sleeve 608 is rotatably mounted on the column 607 through a bearing, and baffles 609 are provided at the top and bottom of the sleeve 608 to limit the narrow reflective film.

[0062] The striping principle of the striping structure of the utility model photovoltaic cell gap reflective film is as follows:

[0063] like Figure 4 As shown, it is a schematic diagram of the winding path of the reflective film. After the unwinding reflective film is tensioned by the tensioning assembly 3, it is transmitted between the upper slitting roller 409 and the lower slitting roller 410. When the cutter 411 is slitting, the cutter 411 will fall into the knife groove 412 of the lower slitting roller 410, thereby cutting the reflective film. At this time, the reflective film has a certain wrap angle in the knife groove 412, and it is not easy to drift. The existence of the knife groove 412 also prevents the cutter 411 from cutting the lower slitting roller 410, which prolongs the service life of the equipment and improves the efficiency of slitting. Finally, under the action of the material shifting assembly 6, multiple groups of narrow reflective films are separated to facilitate subsequent winding.

[0064] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
