Apparatus and method for disassembling solar modules using heating {APPARATUS AND METHOD FOR DISASSEMBLING SOLAR CELL MODULE USING HEATING}

The present invention relates to an apparatus and method for disassembling a solar module, and more specifically, to an apparatus and method for disassembling a solar module using a heating module that simultaneously performs heating and pressurization.

Solar cells, the basic unit of crystalline solar modules, are easily damaged elements. Therefore, solar cells are typically modularized within a sturdy aluminum frame to protect them from external shocks or bad weather. A product made in the form of a solar panel by stacking elements such as tempered glass, filler, solar cells, and filler and then combining cables and distribution boards is called a solar module.

The lifespan of solar modules, which form the core of solar power generation facilities, is approximately 20 to 30 years, and as solar modules in use around the world reach the end of their lifespan, the disposal of discarded solar modules is emerging as an important issue.

A solar module consists of multiple solar cells connected in series or parallel and is used as the basic unit of solar power generation. Solar modules are divided into crystalline silicon solar cells (1st generation), thin film solar cells (2nd generation), and 3rd generation solar cells. Currently, the most widely used solar cell in Korea is a crystalline solar cell whose main material is silicon. These solar modules must be dismantled for reasons such as their efficiency decreasing over time. At this time, it is possible to conserve resources and prevent environmental pollution by recovering and recycling useful materials present in solar modules.

Materials such as front glass, EVA, solar cells, and back sheets that make up solar modules are relatively expensive, and most of them are imported, so there is no way to recover and recycle solar cells and glass. It is being attempted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

Figure 1 is a diagram illustrating a pre-cutting process for solar modules according to an embodiment of the present invention, and Figure 2 schematically shows the configuration of a solar module disassembly device according to an embodiment of the present invention. It is a drawing.

The solar module disassembly device using heating according to an embodiment of the present invention described below first cuts a part of the solar module in order to disassemble the front member and sandwich of the solar module more accurately and easily, It is a device that disassembles the front member and the sandwich using the stepped ledge that is created.

To be more specific, the front member of the solar module is made of glass, and the sandwich is made up of a solar cell, a back sheet, a copper ribbon, and an encapsulant (EVA). The purpose of the solar module disassembly device of the present invention is to separate the front member and the sandwich. For example, the solar module disassembly device of the present invention can separate only the sandwich from the front member, and part of the sandwich (e.g., solar cell, back sheet, copper It may also be implemented by separating the ribbon (and part of the sealant).

When disassembling a damaged solar module, if the entire sandwich including the sealing material is separated leaving only the front member, the broken glass pieces will be scattered, making recovery (recycling) difficult. Accordingly, at least a portion of the sealant remaining with the front member may serve as a remaining film for fixing the broken glass pieces.

The solar module disassembly device may be used in the process of removing part of the solar module 10 during the regeneration process of the solar module 10. For example, a solar module disassembly device may be used to perform partial peeling of a solar module 10 composed of a front member 13 and a sandwich 11.

In the present invention, the sandwich 11 is a layer to be scraped, and the front member 13 may be a member containing tempered glass. The sandwich 11 is scraped and removed by a solar module disassembly device, so that the tempered glass can be recycled. Of course, you can select the recycled part by controlling the scraped part.

Referring to Figure 2, the solar module disassembly device according to an embodiment of the present invention includes a work table 100, a heating module 200, a cutting cutter 300, a scraper 400, and a suction module 500. It can be configured.

The worktable 100 according to an embodiment of the present invention may be configured to include a base 110 and a support block 130, as shown in (a) of FIG. 1. The solar module 10 can be loaded on the base 110, the support block 130 has a shape that protrudes upward from the base 110, and the movement of the solar module 10 with respect to the base 110 can be suppressed.

The heating module 200 according to an embodiment of the present invention can pressurize and heat the upper surface of the solar module 10 loaded on the base 110.

The cutting cutter 300 according to an embodiment of the present invention can cut the cutting target area of the solar module 10 composed of the front member 13 and the sandwich 11. For a more detailed description of the cutting target area to be cut by the cutting cutter 300 according to this embodiment, refer to (b) and (c) of FIG. 1.

Figure 1(b) is a side view of the solar module showing the cutting target area cut, and Figure 1(c) is a top view of the solar module showing the cutting target area cut.

The cutting cutter 300 of the present invention is a preprocessing process performed before the scraper 400 disassembles the solar module 10, and is used to cut the other side of the solar module 10, one side of which is supported on the support block 130. The sandwich (11) can be cut. That is, the cutting target area of the present invention may be set to the edge area of the solar module 10. Here, the edge area may be an area including one edge of the solar module 10 or an area adjacent to one edge of the solar module 10.

Accordingly, as shown in (b) and (c) of Figure 1, which is an embodiment, the solar module 10 is cut into the front member 13 and the sandwich as the sandwich 11 on one side or the other side is cut. A step ridge (A) is created between (11).

Refer to FIG. 2 for a more detailed description of the process by which the cutting cutter 300 cuts the cutting target area.

Referring to Figure 2, the heating module 200 of the solar module disassembly device according to this embodiment is located on the upper surface of the solar module 10 loaded on the base 110, and applies pressure on one side of the cutting target area. The target area can be pressed and the pressurized area can be heated.

In this embodiment, it is assumed that the area to be pressed by the heating module 200 is a part of the solar module next to the area to be cut. However, the area to be pressed by the heating module 200 of the present invention is pressed and heated. The target area may be set as the entire remaining area of the solar module excluding the cutting target area.

In addition, in Figure 2, the solar module decomposition device of the present invention is shown as having only one heating module 200, but according to another embodiment of the present invention, the heating module 200 is the size of the solar module or the heating module. Depending on the size of (200), it may be implemented to be provided in plural pieces.

Figure 3 is a diagram showing a heating module pressurizing a solar module according to an embodiment of the present invention.

Damaged solar modules usually experience bowing as shown in the left drawing of Figure 3. Due to this bending phenomenon, certain parts of the solar module 10 may become bent or curved. Accordingly, the heating module 200 of the present invention presses the solar module 10, which is not flat due to the above-mentioned bending phenomenon, as shown in the right drawing of FIG. 3 to flatten the solar module 10, thereby performing cutting. The cutter 300 can easily cut the cutting target area of the solar module 10.

Figures 4 and 5 are diagrams for a more detailed description of the heating module according to an embodiment of the present invention.

Referring to Figure 4, the heating module 200 according to an embodiment of the present invention may be configured to include a reflector 210, pressure balls 230, a heater 250, and a temperature sensor 270. For example, the heater 250 of the present invention is provided inside the main body of the heating module 200, and can pressurize and simultaneously heat the solar module 10 placed on the base 110.

A plurality of heaters 250 according to one embodiment are provided on the pressurizing balls 230 and can indirectly heat the solar module 10 in contact with the pressurizing balls 230. In the present invention, the pressure balls disposed below the heater 250 may be provided as a pressing member that can be replaced with another pressing means.

The reflector 210 serves as a housing that forms the frame of the heating module 200 of the present invention.

The pressure balls 230 are located below the heater 250 and serve to pressurize the loaded solar module 10, and are designed to allow the heating module 200 to move in one direction along the scraping direction. They can be installed spaced apart at set intervals. In addition, the pressurized balls 230 also serve to ensure that heat generated by the heater 250 is more uniformly transferred to the solar module 10.

Figure 5(a) shows the pressurized balls 230 viewed from the side, and Figure 5(b) shows the pressurized balls 230 viewed from the top or bottom.

As shown in Figure 5, which is an embodiment, the pressurizing balls 230 of the present invention are installed on the lower surface 251 of the heating module 200 to be spaced apart at preset intervals, and the solar module loaded on the base 110 It can be moved with the stomach pressed.

The pressurizing ball 230 of the present invention may be implemented in the form of a circular sphere, as shown in Figure 5, or may be implemented in the form of a long cylinder.

In addition, the pressurizing ball 230 of the present invention can be made of a metal material that does not cause problems even when continuously exposed to a high temperature environment.

Referring again to FIG. 4, the temperature sensor 270 according to this embodiment is a sensor for measuring the temperature inside the reflector 210, based on the temperature inside the heating module 200 measured from the temperature sensor 270. , the surface temperature of the solar module 10 located at the bottom and indirectly heated can be predicted.

The heating module 200 according to an embodiment of the present invention is loaded to assist the scraping operation of the scraper 400 that separates the sandwich 11 of the solar module 10 from the front member 13. The solar module 10 may be indirectly heated so that the surface temperature of the solar module 10 is maintained in the range of 100 to 220 degrees.

Figure 6 is a reference diagram showing the appearance of a solar module scraped according to surface temperature. Figure 6 (a) shows scraping while the surface temperature of the solar module is heated to 100℃ or lower, and Figure 6(b) shows the solar module's surface temperature heated to 150℃. It shows the scraped state, and Figure 6 (c) shows the scraped state when the surface temperature of the solar module is heated to 220°C or higher.

As shown in Figure 6, if the surface temperature of the solar module is scraped while heated to 100°C or lower, the sandwich being peeled off is damaged, the separation efficiency of the solar module decreases, and the surface temperature of the solar module decreases. If scraped while heated above 220℃, the backsheet may be damaged (partially melted) and stick to the solar module disassembly device (equipment).

In the heating module 200 according to an embodiment of the present invention, the faster the predetermined peeling movement speed of the scraper 400 is set to scrape the sandwich 11 of the solar module from the front member 13. , the temperature at which the heating module 200 heats the solar module may be set high. At this time, since the peeling movement speed of the scraper 400 is set in advance before the disassembly operation of the solar module, the heating temperature of the heating module 200 to maintain the surface temperature in the preset temperature range depends on the set peeling movement speed. It can be variable. That is, the peeling movement speed of the scraper and the surface temperature of the solar module can be set proportionally.

In this way, the reason for setting the surface temperature in consideration of the peeling movement speed is that as the scraping speed (peeling movement speed) increases, the time for the solar module to be heated by the heating module 200 decreases, so the speed increases. The faster it goes, the higher the surface temperature of the solar module must be.

Figure 7 is a diagram illustrating a heating module according to various embodiments of the present invention. Referring to Figure 7, the heating module 200 according to this embodiment can pressurize only one side of the cutting target area.

For example, in the present invention, the cutting target area 15 may be set as an area having a length D2 within 5 to 100 mm from one end of the solar module 10. When the cutting target area 15 is set to an area within 5 mm from one end of the solar module 10, the sandwich 11 is cut too small, and the scraper 400 cuts the sandwich 11 and the front member 13. ), there may be a problem where the step difference between the two parts cannot be accurately aligned. In addition, when the cutting target area 15 is set to an area of 100 mm or more from one end of the solar module 10, the cutting cutter 300 must cut a somewhat large area, so reciprocating cutting is required, so the solar module ( 10) has the disadvantage that it takes a relatively long time to decompose. In addition, it is easy to supply ready-made products up to 100 mm in size.

The area to be pressed by the heating module 200 according to this embodiment may be an area at a distance D1 of 10 to 50 mm from the area to be cut 15. If the pressurizing target area is set to an area within 10 mm, the heating module 200 and the cutting cutter 300 pressurizing the area are placed and operated too close to each other, so there is a risk of colliding with each other and cutting. Water may become trapped between the heater module and the cutting cutter. On the other hand, when the pressing target area is set to an area that is more than 50 mm away from the cutting target area 15, the area pressurized by the heating module 200 is too far away from the cutting target area 15, so that the cutting target area 15 There is a problem in (15) that the bowing phenomenon may continue to remain.

For example, the heating module 200 may be implemented as a plate having a length of 100 to 500 mm. In Figure 7, the shape of the heating module 200 is illustrated as being square, but the heating module 200 is not limited thereto. ) can be implemented in various shapes such as circles and polygons.

Figure 8 is a diagram showing a cutting cutter according to an embodiment of the present invention.

The cutting cutter 300 according to this embodiment may be a vertical cutting cutter that cuts the cutting target area by contacting the cutting target area in a direction perpendicular to the cutting target area. For example, the cutting cutter 300 of the present invention may be implemented as a milling cutter, and various types of milling cutters such as plain milling, groove milling, end mill, and T-cutter may be applied, preferably The face cutting method may be applied.

According to the cutting process of the sandwich 11 using a milling cutter, a cutter with multiple cutting edges rotates and each cutting blade discharges chips, so machining efficiency is high and front machining can be generally applied. .

As shown in FIG. 8, the cutting cutter 300 according to this embodiment may include a milling cutter as the cutting cutter blade 310. The sandwich 11 of the solar module 10 may be cut and removed while being transferred to the rotating milling cutter.

The cutting cutter 300 cuts the area to be cut as shown in (b) of Figure 2. At this time, the cutting cutter 300 may move in one direction while rotating and cutting over the cutting target area.

Referring to Figure 2 (a), the suction module 500 of the present invention can suction the sandwich particles 11a that scatter as the remaining area of the cutting target area is cut by the cutting cutter 300.

The scraper 400 according to an embodiment of the present invention uses the step ridge created between the front member 13 and the sandwich 11 as the starting point as the sandwich in the cutting target area is cut by the cutting cutter 300, and cuts the sandwich. (11) can be separated from the front member (13). More specifically, the scraper 400 can scrape the step ridge formed on the sealant between the front member 13 and the sandwich 11 as a starting point.

Figure 9 is a diagram illustrating a process in which a scraper separates a sandwich from the front member according to an embodiment of the present invention.

As shown in FIG. 9, the heating module 200 according to an embodiment of the present invention is configured to move the scraper 400 while the scraper 400 is scraping the sandwich 11 from the front member 13. By moving together in one direction, the remaining solar modules can be continuously pressurized. Likewise, the heating module 200 also moves in one direction in accordance with the movement of the scraper 400 and heats the remaining solar modules.

Referring to Figure 9 (a), the scraper 400 according to the present embodiment starts the scraping operation by using the step ridge (A) of the sandwich 11 and the front member 13 as the scraping start point. do. Accordingly, as the scraper 400 moves in one direction of the solar module 10, the sandwich 11 may be separated from the front member 13, as shown in (b) of FIG. 9.

At this time, the heating module 200 may move in one direction of the solar module 10 in accordance with the movement of the scraper 400. When the scraper 400 cuts all of the sandwich 11 as shown in (c) of Figure 9, the cut sandwich 11 is removed as shown in (d) of Figure 9 and the heating module 200 is a solar module ( 10) The pressurization can be released.

The thickness measurement sensor (not shown) according to this embodiment is located at a position spaced apart from the side of the solar module 10 moved to a predetermined position at a predetermined interval, and the front member 13 of the solar module 10 ) can be measured. The cutting cutter 300 may cut the area to be cut in consideration of the thickness of the front member 13 measured by a thickness measurement sensor (not shown).

The front member 13 (front glass) constituting the solar module 10 is relatively expensive, and most of it is dependent on imports. Therefore, methods to recover and recycle solar cells and glass are being attempted. . The solar module 10 may have a structure in which components such as a front glass and a solar cell are joined by EVA, which is a sealing material and binder.

If the scraper excessively cuts the sandwich 11 to recover the front glass, the front member 13 may be removed. Therefore, the sealing material (EVA layer) between the front glass and solar cell and the sandwich may be removed. It is desirable to preserve and cut the sandwich.

The thickness measurement sensor (not shown) according to an embodiment of the present invention measures the thickness of the front member 13 with the sealant preserved in order to separate the sandwich 11 and the front member 13 with the sealant preserved, as described above. It can be measured. The thickness measurement sensor 900 according to another embodiment of the present invention may be implemented to measure the thickness of the sandwich on the EVA layer.

For example, the thickness of the sealant between the sandwich 11 and the front member 13 is usually 300 to 450 μm. Accordingly, the cutting cutter 300 may cut the area to be cut considering the thickness value of the sandwich or the thickness values of the sealant and the front member measured by a thickness measurement sensor (not shown).

For example, if the solar module 10 loaded on the workbench 100 is a damaged module, the cutting cutter 300 sets the thickness of the sealing material to be preserved together with the front member to 10 to 300 μm, so that the front member The sandwich above or the sandwich and another portion of the sealant may be cut away, leaving at least a portion of the sealant.

In addition, if the solar module 10 loaded on the workbench 100 is an undamaged module, the cutting cutter 300 sets the thickness of the sealing material to be preserved together with the front member to a maximum of 300 μm, so that the front member and the sealing material It can be cut to leave at least a portion of, or can be cut to leave only the front member.
