Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaics, in particular to an anti-fouling mechanism and a laminating machine. Background Art
[0002] The statements in this section merely provide background technology related to the present invention and do not necessarily constitute prior art.
[0003] In the laminator in the photovoltaic field, there will be a phenomenon of film overflow when laminating photovoltaic modules. In order to prevent the film from sticking to the laminator, anti-sticking cloth is needed to cover the photovoltaic modules to be laminated. For example, anti-sticking cloth, glass, film, battery cell, film, backboard and anti-sticking cloth are stacked in sequence for lamination. Among them, the anti-sticking cloth needs to be resistant to high temperature and have anti-stick properties.
[0004] In related technologies, such as Figure 1 As shown, the anti-sticking cloth is set on the frame of the laminator by rotating the roller, and multiple photovoltaic modules are placed on the anti-sticking cloth at one time and enter the laminator for high-temperature lamination. The anti-sticking cloth is circulated through the roller similar to a conveyor belt. Since the anti-sticking cloth has drape, a support beam needs to be set below the draped part of the anti-sticking cloth to support the anti-sticking cloth to avoid large-area contact between the anti-sticking cloth and the base plate and contamination. The static electricity carried by the anti-sticking cloth when it is used in a circular rotation will absorb dirt, such as colloid particles or dust. When the photovoltaic module is located in the dirt adsorption area of the anti-sticking cloth, it is very easy to cause the coating of the coated glass in the photovoltaic module to be damaged, or when the photovoltaic module is cleaned multiple times due to excessive dirt, the cleaning force may not be suitable to cause abnormal cracks in the module, and the yield of the module cannot be guaranteed.

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0032] When the photovoltaic laminator is performing the lamination process, in order to prevent the adhesive film of the photovoltaic module from overflowing and sticking to the laminator, the laminate is usually wrapped in an anti-sticking cloth for high-temperature lamination. For example, a polytetrafluoroethylene cloth with high temperature resistance and anti-sticking effect is used to prevent adhesion in the laminator, thereby causing hidden dangers. Specifically, the anti-sticking cloth, glass, adhesive film, battery cell, adhesive film, backboard and anti-sticking cloth are stacked in sequence for lamination.
[0033] In the related art, the polytetrafluoroethylene cloth can carry the laminated parts to be laminated and transfer the laminated parts to the corresponding position of the cavity in the laminator for lamination. Figure 1 It is a structural schematic diagram of a laminator in the prior art, such as Figure 1 As shown, in order to realize the cyclic operation of the anti-sticking cloth, the anti-sticking cloth 40 needs to be rotated from the working layer of the frame to between the working layer and the bottom plate 30 below. When the anti-sticking cloth 40 passes through the bottom plate 30, because it has drapability, its hanging part contacts with the bottom plate 30, and because the bottom plate accumulates a large amount of dirt such as residual glue and dust, the dirt will adhere to the anti-sticking cloth 40, which makes it easy for the photovoltaic module on the anti-sticking cloth 40 to absorb dirt. The support assembly with multiple rollers is adopted to support below the anti-sticking cloth 40, which can avoid the above problems. Because the anti-sticking cloth 40 rotates and rubs to produce electrostatic field, the glue particles or dust produced by the glue overflow of the adhesive film can be adsorbed. Especially when the anti-sticking cloth 40 transports the last batch of photovoltaic modules to the laminating chamber for lamination and stops rotating, due to the effect of the electrostatic field, a strip of dirt will be concentratedly adsorbed on the anti-sticking cloth 40 near the position of the support assembly, thereby forming multiple dirt belts that run through the width direction of the anti-sticking cloth 40 at the hanging part of the anti-sticking cloth 40. When the previous batch of photovoltaic modules on the working layer is laminated, the anti-sticking cloth 40 starts to rotate again to transport the next batch of photovoltaic modules to be laminated, and the multiple dirt belts at the hanging part rotate and come to the working layer to carry the photovoltaic modules to be laminated. At this time, when the photovoltaic modules to be laminated happen to be located in a dirt belt area, the dirt will be transferred to the photovoltaic modules, which can easily cause damage to the coating of the coated glass in the photovoltaic modules, or when the photovoltaic modules are cleaned multiple times, the modules may be abnormally cracked due to inappropriate cleaning strength, and the yield of the modules cannot be guaranteed.
[0034] Furthermore, when the photovoltaic components to be laminated are switched in format, since the support assembly is fixedly mounted on the bottom plate 30, the spacing between the multiple dirt strips formed by the support assembly on the anti-sticking cloth 40 is constant. After rotating to the working layer, it will inevitably touch the photovoltaic components to be laminated whose size has changed due to the format switching, and it is inevitable to be contaminated. The roller-type support assembly in the prior art must also ensure that the linear speed of the roller is consistent with the rotation speed of the anti-sticking cloth 40 to avoid the contamination problem, but it needs to increase additional kinetic energy, resulting in a certain amount of energy consumption.
[0035] In response to the above-mentioned problems, the anti-fouling mechanism provided by the exemplary embodiment of the utility model adjusts the intervals between the multiple dirt belts generated at the position of the support beam by setting the support beam to have adjustable spacing, and adjusts and adapts according to the size changes caused by the format switching of the photovoltaic components to be laminated, so that when it is rotated to the working layer, each subsequent photovoltaic component to be laminated is located exactly between two adjacent dirt belts, or in other words, the position of the dirt belt in the working layer is adjusted to be located in the gap position of each photovoltaic component to be laminated, thereby effectively avoiding the introduction of dirt into the photovoltaic components to cause batch abnormalities.
[0036] Figure 2 Schematic diagram of the structure of the anti-fouling mechanism according to the embodiment of the utility model. Figure 2 As shown, the anti-fouling mechanism provided by the exemplary embodiment of the utility model includes a base plate 30, at least one first slide rail 20 and a plurality of support beams 10 for supporting the overhanging portion of the anti-sticking cloth 40; at least one first slide rail 20 is arranged on the base plate 30, and the first slide rail 20 extends along the movement direction of the anti-sticking cloth 40; each support beam 10 is slidably arranged on at least one first slide rail 20, and a plurality of support beams 10 are distributed along the movement direction of the anti-sticking cloth 40; the anti-fouling mechanism also includes a plurality of fixed structures, and each support beam 10 is detachably connected to a corresponding position of the base plate 30 through a corresponding fixed structure.
[0037] Exemplarily, the number of first slide rails 20 can be determined according to actual needs. For example, three first slide rails 20 are distributed along the width direction of the anti-sticking cloth 40, one of which is located in the middle, and the other two are located near the two sides of the bottom plate 30, so as to provide a more stable sliding and load-bearing support beam 10.
[0038] In practical applications, a plurality of support beams 10 are spaced apart along the moving direction of the anti-sticking cloth 40 to support the overhanging portion of the anti-sticking cloth 40, to prevent the anti-sticking cloth 40 from contacting the bottom plate 30 over a large area, thereby preventing the anti-sticking cloth 40 from being stained by dirt dropped on the bottom plate 30. Three first slide rails 20 are arranged along the width direction of the anti-sticking cloth 40, that is, perpendicular to the moving direction of the anti-sticking cloth 40, and the length direction of the first slide rails 20 is the moving direction of the anti-sticking cloth 40. The support beams 10 are slidably arranged on the three first slide rails 20. When the photovoltaic modules to be laminated are switched in format and the size changes, the positions of the support beams 10, that is, the spacing between the support beams 10, can be adjusted. When the positions are adjusted in place, the corresponding support beams 10 can be fixedly connected to the corresponding positions of the bottom plate 30 through the fixing structure. Based on this, when the anti-adhesive cloth 40 stops rotating while transporting the photovoltaic modules to the lamination position during the lamination process, due to the effect of the electrostatic field, multiple strips of dirt will be concentratedly adsorbed at the position of the anti-adhesive cloth 40 close to the support beam 10, and the spacing between the multiple dirt strips is also adapted to the size of the photovoltaic modules to be laminated, so that the next batch of photovoltaic modules to be laminated can avoid contact with the dirt strips when they move to the anti-adhesive cloth 40 located on the working layer. That is, by adjusting the spacing between the various support beams 10, the spacing between the various dirt strips can be adjusted, so that the photovoltaic modules to be laminated are located between the two dirt strips on the working layer, or the dirt strips are located in the gap between the photovoltaic modules to be laminated, thereby avoiding the adsorption of dirt on the module surface, and further, the cleaning frequency can be reduced, thereby reducing the risk of abnormal hidden cracks caused by excessive cleaning force, and the risk of abnormal photovoltaic module outflow.
[0039] Furthermore, since the photovoltaic laminator is generally designed with a multi-layer structure and the spacing between layers is small, the plastic particles dropped from the bottom plate 30 and the glass fragments generated after the glass in the laminator is broken are not easy to be quickly cleaned due to the obstruction of the support beam 10. By setting the support beam 10 with an adjustable spacing, it is convenient to quickly clean the broken glass in the laminator. At the same time, since only the bottom plate 30 of the laminator is modified, the modification cost and maintenance cost are low.
[0040] Figure 3 It is a structural schematic diagram of a support beam of an anti-fouling mechanism according to an embodiment of the utility model; Figure 6 yes Figure 3 Schematic diagram of the top view of the structure. Figure 3 and Figure 6 As shown, the base plate 30 also includes side plates 31 arranged on both sides of the base plate 30, each fixing structure includes a locking device and a locking block 13, and the two ends of each support beam 10 are connected to the locking blocks 13. The two locking blocks 13 on each support beam 10 are respectively detachably connected to the two side plates 31 through corresponding locking devices.
[0041] When the support beam 10 is adjusted to the right position to adapt to the size of the photovoltaic module to be laminated, the locking blocks 13 connected at both ends of the support beam 10 can be fixedly connected to the corresponding side panels 31 by locking devices, such as bolts. It should be understood that the side panels 31 can have multiple screw holes or through holes arranged at intervals. The locking blocks 13 are fixed to the corresponding positions of the side panels 31 by bolt connection, that is, the support beam 10 is fixed at this position. When the spacing of the support beam 10 needs to be adjusted, the bolts on the locking blocks 13 are loosened, and the support beam 10 can slide along the length direction of the three first slide rails 20 until the next fixed position and then fixedly connected using a fixed structure.
[0042] Considering that the anti-adhesive cloth 40 will produce a dirt belt when it contacts the support beam 10 when it rotates to the support beam 10, in order to reduce the dirt on the anti-adhesive cloth 40. Figure 4 and Figure 5 As shown, Figure 4 yes Figure 3 A side view structural schematic diagram of; Figure 5 yes Figure 3 The support beam 10 includes a beam body 11 and at least one dirt collecting box, the dirt collecting box is located on one side of the beam body 11, the dirt collecting box extends along the length direction of the beam body 11, and the length of the dirt collecting box is greater than or equal to the width of the anti-sticking cloth 40.
[0043] Exemplarily, the dirt collecting box is arranged along the entire length of the beam body 11. Since the length of the beam body 11 is greater than or equal to the width of the anti-sticking cloth 40, the length of the dirt collecting box is greater than or equal to the width of the anti-sticking cloth 40. Thus, the dirt within the entire width of the anti-sticking cloth 40 can fall into the dirt collecting box.
[0044] like Figure 4 As shown, two dirt collecting boxes are provided on each support beam 10, which are respectively located on both sides of the beam body 11, so as to collect dirt on the anti-sticking cloth 40 in a larger range.
[0045] When the dirt collecting box is full of dirt, in order to effectively clean the dirt collecting box, the anti-fouling mechanism provided by the exemplary embodiment of the utility model sets the dirt collecting box to be detachably connected to the beam body 11, so that the dirt collecting box can be removed for easy cleaning.
[0046] For example, the dirt collecting box can be connected to the beam body 11 by a common bolt connection method.
[0047] In other embodiments, Figure 4 and Figure 5As shown, there is a second slide rail 12 between the dirt collection box and the beam body 11, and the dirt collection box can be slidably arranged on the beam body 11 through the second slide rail 12. The dirt collection box can be implemented in a pull-out manner, which is convenient for cleaning the dirt of the laminator and easier to maintain. For example, the second slide rail 12 can adopt the slide rail method adopted by commercially available drawers, which will not be repeated here.
[0048] like Figure 4 and Figure 5 As shown, the dirt collecting box provided by the exemplary embodiment of the utility model has an opening 143, a bottom wall opposite to the opening 143, and a cavity connected to the opening 143; along the direction from the opening 143 to the bottom wall, the cross-sectional area of the cavity increases. That is, the cavity of the dirt collecting box becomes larger and larger from the top to the bottom. The use of this cavity structure with a narrow top and a wide bottom shape can facilitate the sliding of dirt, and it is not easy to bring the dirt out of the cavity for a second time, thereby reducing the possibility of dirt contaminating the components.
[0049] In some embodiments, Figure 5 As shown, the dirt collecting box has a first side wall 141 and a second side wall 142 opposite to each other, the second side wall 142 is close to the beam body 11, and along the direction from the opening 143 to the bottom wall, the first side wall 141 extends to the bottom wall in a direction away from the second side wall 142. Specifically, the first side wall 141 is arranged on a side of the second side wall 142 away from the beam body 11, and the first side wall 141 is inclined from top to bottom in a direction away from the second side wall 142, and this embodiment can make it easier for dirt to slide down to the bottom wall of the dirt collecting box.
[0050] In order to collect the dirt from the anti-sticking cloth 40 into the dirt collection box as much as possible, the dirt collection box provided by the exemplary embodiment of the utility model further has a guide portion 144 connected to the portion of the first side wall 141 located at the opening 143, and the guide portion 144 extends in a direction away from the second side wall 142 along the direction from the bottom wall to the opening 143. The guide portion 144 is located above the first side wall 141. Exemplarily, the guide portion 144 can be integrally formed with the first side wall 141, and the guide portion 144 can be regarded as two surfaces opposite to the inclination direction of the first side wall 141, that is, the guide portion 144 extends from bottom to top in a direction away from the second side wall 142. The guide portion 144 can expand the collection range of the opening 143 of the dirt collection box so that more dirt can be collected into the cavity of the dirt collection box.
[0051] In some embodiments, considering that the photovoltaic modules are standard parts of the same size and the intervals between the photovoltaic modules are the same, the arrangement of the multiple support beams 10 is evenly distributed on the bottom plate 30, so that the dirt band on the anti-sticking cloth 40 can be evenly distributed, so that when it is rotated to the working layer, it is located in the intervals between the photovoltaic modules, thereby avoiding contamination of the photovoltaic modules and reducing the difficulty of cleaning and the risk of abnormal quality outflow.
[0052] Exemplarily, the anti-sticking cloth may be polytetrafluoroethylene cloth, or other types of cloth with high temperature resistance, such as aramid cloth.
[0053] The exemplary embodiment of the present utility model further provides a laminating machine, comprising an anti-sticking cloth and the above-mentioned anti-fouling mechanism, wherein the anti-sticking cloth is rotatably arranged in the laminating machine, and the anti-fouling mechanism is located below the anti-sticking cloth.
[0054] Compared with the prior art, the advantages of the laminator of the exemplary embodiment of the utility model are the same as those of the above-mentioned anti-fouling mechanism, which will not be described in detail here.
[0055] Those skilled in the art should understand that the above embodiments are only for the purpose of clearly illustrating the present invention, and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications may be made based on the above disclosure, and these changes or modifications are still within the scope of the present invention.
