1 is a view showing a waste solar cell scrap crushed waste solar cell cells, Figure 2 is a view for explaining the type of waste contained in the waste solar cell scrap.

The scraps of the waste solar cells obtained by disassembling the collected solar cell modules are mixed in various configurations, the busbar ribbon of FIG. 2(a), the interconnector ribbon of FIG. 2(b), and the solar cell of FIG. 2(c). Scraps are mixed. Since the busbar ribbon and the interconnector ribbon are metal materials for transmitting electricity, and the solar cell cell scrap is made of silicon or compound semiconductor depending on the type of the solar cell, it is possible to recycle sufficiently by separating and separating them.

3 is a schematic diagram showing the configuration of a waste solar cell scrap sorting device according to an embodiment of the present invention, and FIG. 4 is a view for explaining the operation of the waste solar cell scrap sorting device.

The waste solar cell scrap sorting apparatus of this embodiment comprises a ribbon sorter 100, a cell shredder 200, and a sorter 300, and a flow chart for a waste solar cell scrap sorting method of this embodiment using the same is shown in FIG. It was shown in.

The ribbon aligner 100 is a portion for aligning the interconnector ribbon in the longitudinal direction for ease of selection, and a scrap supplying step (S100) and an interconnector ribbon aligning step (S200) are performed. As shown in FIG. 2, the bus bar ribbon is composed of a finger bar extending from a relatively thick bus bar and a bus bar, and thus the overall size is large and the area occupied is large, so mechanical sorting with solar cell scrap is easy. However, the interconnector ribbon for connecting the photovoltaic cell and the photovoltaic cell is difficult to scrap and mechanically sort the photovoltaic cell, as shown in FIG. 2(b), because it is simply a long strip.

The ribbon aligner 100 is a part that arranges the long ribbon-shaped interconnector ribbons in parallel in the traveling direction to facilitate mechanical sorting with solar cell scraps to be processed later.

Specifically, the ribbon aligner 100 of this embodiment includes a loading unit 110, an alignment unit 120, and a vibration unit 130.

The loading unit 110 is a portion in which the scrap of the waste solar cell scrap of FIG. 2 is raised, and a scrap supply step (S100) is performed, and the scrap of the waste solar cell in which the solar cell cell scrap and various ribbons are mixed is the vibration of the vibration unit 130 It spreads evenly by and gradually moves in the direction of the arrow.

The alignment unit 120 is a portion that aligns the interconnector ribbon included in the scrap of the waste solar cell so as to be arranged side by side in the traveling direction, and the interconnector ribbon alignment step (S200) is performed. In this embodiment, the alignment unit 120 is configured to have a plurality of grooves arranged side by side in the traveling direction, and in the process of moving the scrap of the waste solar cell in the direction of the arrow by the vibration of the vibration unit 130, FIG. As shown in the interconnector ribbon included in the scrap of the waste solar cell is arranged in the longitudinal direction along the groove.

6 is a perspective view for explaining the structure of an alignment unit applied to the waste solar cell scrap sorting device of this embodiment.

The alignment part 120 is a shape in which a concave concave portion and a convex protrusion having a cross section perpendicular to the traveling direction are repeated, and the concave grooves constituting the concave portion extend side by side in the longitudinal direction. When vibration is applied to the alignment unit 120 by the vibration unit 130, the long ribbon-shaped interconnector ribbon is arranged side by side in the traveling direction by the groove. The height difference and the gap between the recesses and protrusions are configured to a suitable size according to the size of the scrap of the waste solar cell, and should be at least thicker than the thickness of the interconnector ribbon to align the interconnector ribbon. In general, the grooves should be deeper and wider than the thickness of the interconnect ribbon having a thickness of 0.2 mm. If the ribbons to be aligned are thicker, the grooves are deeper and wider.

Further, in order to further increase the efficiency of alignment, two or more types of grooves having different widths and depths may be formed, and grooves having a relatively narrow width and depth may be additionally formed on the surface of the grooves having a relatively wide width and depth. .

At this time, the bus bar ribbon including the bus bar and the finger bar is not completely aligned by the alignment unit 120, but since its shape is complicated, there is no difficulty in screening at a later stage.

The vibration unit 130 is a device for applying vibration to the loading unit 110 and the alignment unit 120, and in this embodiment, a separate configuration for moving the scrap of the waste solar cell is not applied, and the vibration unit 130 The waste solar cell scrap was configured to proceed to the right by vibration.

On the other hand, when an excessive amount of scrap of the waste solar cell is placed on the alignment unit 120, there is a problem that alignment and movement due to vibration of the vibration unit 130 becomes difficult. Although not shown, a portion of the waste transferred from the loading unit 110 to the alignment unit 120 is provided with a control gate to limit the height of the scrap of the waste solar cell passing by, so that the waste solar cells of a predetermined amount or less are installed in the alignment unit 120. It can be configured to load only scrap.

The cell shredder 200 is a part that enables solar cell cells to be separated and sorted by receiving only the solar cell scrap and the bus bar ribbon and the interconnector ribbon aligned in the direction of travel, and crushing only the solar cell scrap. The crushing step (S300) is performed.

The cell crusher 200 of this embodiment includes a conveyor belt 210 and crushing means 220.

The conveyor belt 210 transports scraps of the waste solar cells that have been transferred from the ribbon aligner 100, and is a space where the crushing process by the crushing means 220 is performed.

The crushing means 220 is a configuration that crushes scraps of the waste solar cell at the top of the conveyor belt 210, and the illustrated configuration rotates at the top of the conveyor belt 210 and compresses the scraps of the waste solar cells being transferred, thereby compressing the solar cells. It is a crushing roll that crushes only cell scrap. The crushing means 220 is not only applicable to the crushing roll, but may also apply a punch or the like that strikes the waste solar cell scrap while moving up and down. In order to recover the solar cells separately from the ribbon, the solar cells must be shredded to a small size. At this time, the size at which the solar cell cell scrap is shredded is related to the length of the ribbon, and for separation and separation from the ribbon, it is preferable that the size is less than 50% of the shortest length among the target ribbons. For example, when selecting a 6-inch solar cell cell scrap, the shortest length of the ribbon used for the 6-inch cell is about 160 mm, so the solar cell scrap is crushed to a size of less than 80 mm.

7 is a view for explaining the structure of the shredding roll applied to the waste solar cell scrap sorting device of the present embodiment.

The crushing means 220 is composed of a roller body and a plurality of protrusions 221 formed on its surface. When the roller body of the crushing means 220 rotates on the upper part of the conveyor belt 210, the waste solar cell scrap is subjected to pressure as it passes between the crushing means 220 and the conveyor belt 210. At this time, a stronger pressure is partially applied to the scrap of the waste solar cell by the protrusion 221, and the brittle solar cell cells are further crushed. The bus bar ribbon and the interconnect ribbon are not crushed because of their ductility, and furthermore, they do not affect the arrangement of the interconnect ribbons aligned in the direction of travel.

In the drawing, only a case in which one crushing means 220 is applied is illustrated, but is not limited thereto. In order to crush a solar cell to a desired size, two or more crushing rolls may be applied, and the shape and size of each crushing roll may be different. For example, the size and spacing of the projections can be adjusted to control the size at which the solar cell cell scraps are crushed, and a plurality of crushing rolls having different projection sizes and intervals can be applied or used in combination with different types of crushing means. It can be crushed.

As previously described in the alignment unit 120, even when an excessive amount of scrap of the waste solar cell is placed on the shredder 200, a problem that crushing becomes difficult occurs. Although not shown, a control gate for limiting the height of the scrap of the spent solar cell scrap may be installed to configure the conveyor belt 210 to load only the scrap of the waste solar cell or less.

The sorter 300 is a part for separating and separating the solar cell and the bus bar ribbon and the interconnector ribbon by recovering the shattered solar cell, and the cell and ribbon sorting step (S400) is performed.

The selector 300 of the present embodiment includes a vibration plate 310 and a vibration part 330 in which a recovery hole 320 is formed.

The vibrating plate 310 moves the scrap of the waste solar cell by vibration of the vibrating unit 330, and recovers only the scrap of the solar cell crushed through the recovery hole 320 formed therein. The recovery hole 320 may be formed according to the size of the photovoltaic cell that is additionally shredded in the cell shredder 200. It does not pass and moves to the end of the diaphragm 310.

8 is a view for explaining the structure of the diaphragm applied to the waste solar cell scrap sorting device of this embodiment.

Since the solar cell included in the scrap of the waste solar cell is additionally crushed by the cell shredder 200 and its size is very small, a through-hole recovery hole 320 is applied as shown in FIG. 8(a). It is possible to recover.

In addition, as shown in FIG. 8(b), a solar cell cell scrap may be recovered by forming a recovery gap 322, which is divided into a gap perpendicular to the traveling direction. As shown in FIG. 4, the recovery gap 322 may be applied as a method of separating the diaphragm 310 into a plurality and spacing the gaps therebetween. In the present invention, since the interconnector ribbon moves relative to the side aligned in the traveling direction, it can be moved to the end of the diaphragm 310 without falling into the recovery gap 322, which is divided into a gap perpendicular to the traveling direction. In the case of a bus bar ribbon having a complicated shape, it naturally goes to the end of the diaphragm 310 without falling into the recovery gap 322.

In the case of recovering the solar cell through the recovery hole 320, there is an advantage that there is little fear of the ribbons falling out and recovering together. In the case of recovering the solar cell through the recovery gap 322, the solar cell is not recovered and has the advantage that there is no fear of moving with the ribbons by moving to the end of the diaphragm 310.

The solar cell cell scrap, which has fallen below the diaphragm 310 through the recovery hole 320, is collected by the cell recovery bin 430, and the bus bar ribbon and the interconnector ribbon moved to the end of the diaphragm 310 have a ribbon recovery bin ( 440), it is possible to separate and recover the solar cell scrap and ribbon contained in the scrap of the waste solar cell.

The sorter 300 performs separation by the size difference between the crushed solar cell cell scrap and the ribbon, and the present invention sends the sorter ribbon to the sorter by arranging the interconnector ribbon for this purpose, but when the ribbon moves upright It may fall into the recovery hole 320 or the recovery gap 322. Although not shown, when the cover to limit the height of the passing object is installed on the upper side of the sorter 300, the erected ribbon is caught by the cover and can be prevented from falling into the recovery hole 320 or the recovery gap 322.

Furthermore, a plurality of partition walls may be installed on the surface of the diaphragm 310 in parallel with the direction in which the scrap of the waste solar cell moves. By installing a plurality of partition walls on the path of the waste solar cell scrap, it is possible to prevent the phenomenon that a large number of ribbons are aggregated and moved.

On the other hand, between the ribbon aligner 100 and the cell shredder 200 and between the cell shredder 200 and the sorter 300, the intermediate collection bins 410, 420 can be installed to collect solar cell cell scrap. .

When a first gap G1 having a predetermined interval is formed between the ribbon aligner 100 and the cell shredder 200, the process of moving the scraps of the waste solar cells past the ribbon sorter 100 to the cell shredder 200 In the photovoltaic cell scrap below a predetermined size falls into the first gap G1. A first intermediate recovery container 410 may be installed under the first gap G1 to separate and collect only solar cell scrap.

Similarly, when a second gap G2 having a predetermined interval is formed between the cell shredder 200 and the sorter 300, the waste solar cell scrap past the cell shredder 200 moves to the sorter 300. The solar cell cell scrap having a predetermined size or less falls into the second gap G2. A second intermediate recovery container 420 may be installed under the second gap G1 to separate and collect only solar cell scrap.

On the other hand, unlike the embodiments described so far, it is also possible to change the arrangement order of the cell shredder 200 and the ribbon aligner 100. In this case, the cell scrap shredding step is first performed in the cell shredder 200, and the scraps of the waste solar cells in which the solar cell scraps are shredded are transferred to the ribbon aligner 100, and the scraps of the waste solar cells in the ribbon sorter 100 The interconnect ribbon alignment step in which the interconnect ribbon included in the alignment is aligned side by side in the progress direction is performed. A cell and ribbon sorting step in which the solar cell scrap and the ribbon are separated and recovered is performed by inserting a scrapped solar cell scrap in which the solar cell cell scrap is shredded and the interconnector ribbon is aligned into the sorter 300.

Each configuration and step is not significantly different from the above-described embodiment, a detailed description thereof will be omitted because it can be applied as it is without detracting from the features of the present invention.

In addition, the cell shredder 200 and the ribbon aligner 100 are provided with only one, respectively, and are not limited to performing the interconnect ribbon alignment step and the cell scrap shredding step once. It is also possible to install the ribbon aligners 100 before and after the cell shredders 200, or to install the cell shredders 200 before and after the ribbon sorters 100 respectively.

The present invention has been described through preferred embodiments, but the above-described embodiments are merely illustrative of the technical idea of the present invention, and various changes are possible within the scope of the present invention. Anyone with ordinary knowledge will understand. Therefore, the protection scope of the present invention should be interpreted by the matters described in the claims, not by specific embodiments, and all technical ideas within the equivalent range should be interpreted as being included in the scope of the present invention.
