Description

Technical Field

[0001] The present invention relates to a disassembly device for the exterior of a solar module (external structures such as frames and junction boxes), and more particularly, to a disassembly device for the exterior of a solar module that can more effectively disassemble the frame of the solar module and can also simultaneously disassemble the frame and the junction box.

Background Art

[0002] The development of clean energy for reducing environmental pollution is accelerating. The development of clean energy is being promoted in various ways through national support projects and the like. Clean energy technologies include not only technologies for energy management, transportation, storage, etc. that manage the generated electricity, but also various new renewable energy technologies using biomass. As power generation technologies, solar power generation and wind power generation that generate electricity using natural energy without using fossil fuels are continuously being studied.

[0003] In particular, since the development of solar power generation, the power generation efficiency has been significantly improved through continuous technological improvements, and as a result, it is currently positioned as an alternative energy technology that is attracting attention. It can be easily applied to areas where it is difficult to install existing power generation facilities, etc., has almost no environmental damage, and can be installed by utilizing conventional buildings and facilities, so the number of solar power generation facilities has been on the increase trend.

[0004] However, solar power generation facilities also need to be replaced and discarded when the lifespan of the solar cells expires, and they have the problem of maintenance management associated with this. In particular, as the number of solar power generation facilities, as well as the application unit and area, have expanded, there has been a need for the work of replacing and discarding aged solar cells on a large scale. However, many solar power generation facilities are an aggregate of solar modules in which solar cells are incorporated into frames and modularized, and since this solar module has a structure in which glass plates and the like are laminated, it is difficult to simply discard it, which has become a major problem in the management of large-scale solar power generation facilities.

[0005] For example, when disposing of a solar module, it may be necessary to first separate the internal panel containing the solar cells (the internal structure consisting of a glass plate and a film-like laminate containing the solar cells stacked on top of it) from the exterior components such as the frame. Furthermore, if there are other exterior components (such as a junction box), these structures must also be removed first. If these operations are not carried out smoothly, it will not only disrupt subsequent processes but also complicate and delay the entire solar module disposal process, thus requiring appropriate countermeasures.

[0006] [Patent Document 1] Korean Published Patent No. 10-2021-0083721 (July 7, 2021) [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] The technical problem of the present invention is to solve the aforementioned problem and to provide a solar module exterior dismantling device that can easily dismantle the exterior of a solar module, and in particular to provide a solar module exterior dismantling device that can more effectively dismantle the frame of a solar module and can simultaneously dismantle the frame and the junction box.

[0008] The technical problems of the present invention are not limited to those described above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0009] The solar module exterior dismantling device according to the present invention is for dismantling the exterior of a solar module, which is composed of a plate-shaped module body made of a glass plate and a laminated film portion including solar cells laminated on the glass plate, a frame surrounding the edge of the module body, and an exterior including a junction box attached to the outer surface of the laminated film portion in a protruding manner, and includes a position adjustment plate that supports one surface of the module body from below the solar module and is movable up and down, a plurality of frame separation blades disposed above the position adjustment plate and moving parallel to the surface of the module body between a first position inside the frame and a second position outside the frame, and a plurality of pressure cylinders each connected to the plurality of frame separation blades, and includes a pressure drive unit that advances the plurality of frame separation blades from the first position to the second position by the pressure cylinders, thereby pressurizing the frame to the outside of the module body and dismantling it, and at least one of the plurality of frame separation blades is composed of foldable variation blades that fold when retracting to the first position and unfold when advancing to the second position to make close contact with the entire side of the frame.

[0010] The multiple frame-separating blades are composed of four foldable variable blades, which gather in a folded state inside the frame at the first position, and then unfold linearly as they advance to the second position, allowing them to adhere closely to each of the four sides of the frame.

[0011] The folding variable blade may include at least two rotating blades that rotate in the forward direction of the frame separation blade at a first position around an axis and fold, and then rotate in the opposite direction and unfold linearly when in contact with the frame.

[0012] The end of the rotating blade slides linearly from the inside to the outside of the frame while in close contact with the frame, thereby applying pressure to the corners of the frame.

[0013] The rotating blade may further include a rotation limiting portion on one side of the rotating blade that limits the maximum rotation angle of the rotating blade and fixes the blade surface of the rotating blade in a state parallel to the frame.

[0014] The folding variable blade may further include a central fixed blade positioned between the two rotating blades and connected to each of the rotating blades by an axis.

[0015] The junction box separation blade may further include one positioned on at least one of the plurality of frame separation blades, the frame separation blade having a portion of which is formed to protrude rearward in the forward direction, and having at least one junction box dismantling groove into which the junction box is inserted.

[0016] The gripper may further include a movable claw coupled to the frame separation blade, which grips the frame and brings it into close contact with the frame separation blade.

[0017] The movable claw is connected at one end to a fixed shaft that is fixed to the frame separation blade, and can be folded or unfolded by rotating around the fixed shaft.

[0018] The gripper may further include a sensor unit that senses the frame on one side of the frame separation blade and generates a sensing signal, and an operating cylinder that is hinged to a hinge shaft located on the movable claw, spaced apart from the fixed shaft, and drives the movable claw by pushing and pulling the hinge shaft with fluid pressure in response to the sensing signal. [Effects of the Invention]

[0019] According to the present invention, during the disposal process of a solar module, particularly the disassembly operation of the exterior (such as the frame, junction box, etc.) corresponding to the preceding process can be easily carried out. According to the present invention, the frame of the solar module can be disassembled simply and effectively, and it is also possible to simultaneously disassemble the frame and the junction box, which is another exterior, in a single process. Further, according to the present invention, since uniform pressure can be applied up to the end of the corner portion of the frame by the folding variable blade, the separation of the frame becomes easier, and by restraining the frame during the disassembly operation, safety accidents such as the frame popping out due to the elasticity of the metal frame can be effectively prevented.

[0021] The advantages and features of the present invention, as well as methods for achieving them, will become clearer with reference to the embodiments described below in detail, along with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and can be realized in a variety of different forms, and these embodiments are provided merely to complete the disclosure of the present invention and to fully inform those who are ordinary skill in the art to which the invention pertains, of the scope of the invention, and the present invention is defined solely by the claims. Throughout the specification, the same reference numerals refer to the same components.

[0022] In the following, the solar module exterior dismantling apparatus according to the present invention will be described in detail with reference to Figures 1 to 16. First, one embodiment of the present invention will be described in detail with reference to Figures 1 to 10, and then, second and third embodiments of the present invention will be described in detail with reference to Figures 11 to 16.

[0023] Figure 1 is a perspective view of a solar module casing dismantling device according to one embodiment of the present invention, and Figure 2 shows the frame separation blade and pressurizing drive unit of the solar module casing dismantling device of Figure 1 together with the solar module.

[0024] Referring to Figures 1 and 2, the solar module exterior dismantling apparatus 1 according to the present invention dismantles the frame of a solar module by linearly driving a plurality of frame separation blades 100 (see Figure 2). The frame separation blades 100 are slidably positioned on the upper part of a position adjustment plate, and the lower position adjustment plate (see 400 in Figure 1) rises to bring the inner structure [module body A'] of the frame A3 of the solar module (see A in Figure 2) into close contact with the frame separation blades 100. The frame separation blades 100 move horizontally along the module body A' of the solar module A to dismantle the frame A3.

[0025] In particular, the frame separation blade 100 is composed of a foldable variable blade that folds when retracting inward from frame A3 and unfolds when advancing outward from frame A3. The frame separation blade 100, composed of a foldable variable blade, has a structure in which the rotating blade 101 folds or unfolds while rotating. As shown in Figure 2, when it comes into contact with frame A3 while advancing from a folded state in the retracted position, it can unfold and make close contact with the entire side of frame A3. Therefore, by unfolding the frame separation blade 100, it is possible to effectively apply pressure even to the corners of frame A3 (see enlarged view in Figure 8), which were previously difficult to apply pressure to.

[0026] The detailed configuration of the solar module exterior dismantling apparatus 1 of the present invention is as follows: The solar module exterior dismantling apparatus 1 consists of a plate-shaped module body (see A' in Figure 2) made up of a glass plate and a laminated film section containing solar cells laminated on the glass plate, a frame surrounding the edge of the module body (see A3 in Figure 2), and a junction box (junction) attached to the outer surface of the laminated film section in a protruding manner. A solar module exterior dismantling device for dismantling the exterior of a solar module (see Figure 2A) to which an exterior (box) (see Figure 2A) is attached is provided, comprising: a position adjustment plate 400 that supports one side of the module body from below the solar module and is movable up and down; a plurality of frame separation blades 100 positioned above the position adjustment plate 400 and moving parallel to the surface of the module body between a first position inside the frame and a second position outside the frame; and a plurality of pressure cylinders 210 each connected to the plurality of frame separation blades 100, and a pressure drive unit 200 that advances the plurality of frame separation blades 100 from the first position to the second position by the pressure cylinders 210, thereby pressurizing the frame outward from the module body and dismantling it, wherein at least one of the plurality of frame separation blades 100 is a foldable variable blade that folds when retracting to the first position and unfolds when advancing to the second position to make close contact with the entire side of the frame.

[0027] In one embodiment of the present invention, the solar module casing dismantling device 1 comprises a plurality of frame separation blades 100, each composed of four foldable variable blades, which are assembled in a folded state inside the frame at the first position (see Figure 2), and then unfold linearly as they advance to the second position, allowing them to adhere closely to each of the four sides of the frame (see Figure 8). In this embodiment, the frame separation blades 100 are substantially identical to foldable variable blades.

[0028] The foldable variable blade may include at least two rotating blades 101 that rotate in the forward direction of the frame separation blade 100 in a first position around an axis and fold, and then rotate in the opposite direction and unfold linearly when in contact with the frame. That is, each frame separation blade 100 may be formed of a foldable variable blade having a variable structure in which at least two rotating blades 101 are folded or unfolded.

[0029] However, the technical concept of the present invention is not limited to this embodiment, and the structure of the foldable variable blade can also be applied to only a part of the frame separation blade 100.

[0030] The following describes in more detail the configuration and effects of the present invention based on one embodiment of the present invention.

[0031] First, with reference to Figure 2, the exterior and solar module A to which the present invention applies will be briefly described. Solar module A is formed by integrating multiple solar cells and may include protective equipment for integrating and protecting such solar cells. Solar module A includes an internal structure arranged in a plate shape inside frame A3, frame A3 surrounding the edges of the internal structure, and a junction box A4 formed protruding from the surface of the internal structure. The solar cells are contained within the internal structure, and frame A3 and junction box A4 are external structures, corresponding to the exterior of solar module A as defined in the present invention. The internal structure forms a plate-shaped module body A', and module body A' includes a glass plate (see A1 in Figure 5) and a laminated film portion having solar cells laminated on the glass plate A1 (see A2 in Figure 5). In this specification, the internal structure of the solar module is the same as module body A'. Frame A3 plays a role in surrounding and protecting the edges of module body A' and may be formed of a metal structure such as an aluminum bar.

[0032] The glass plate A1 of the module body A' is placed on the front surface (i.e., the light incidence surface) of the solar module A when actually in use, and serves to protect the laminated film section A2 from contamination and maintain its shape. The solar cells may be contained within the laminated film section A2, and the laminated film section A2 may also include encapsulation films and back sheets placed on both sides of the solar cells. The junction box A4 is a box-shaped structure placed on the outer surface of the laminated film section A2 (i.e., the back surface opposite the light incidence surface) and is used for cable connections and the like.

[0033] This embodiment will primarily describe frame dismantling using the variable structure of the frame separation blade 100. The simultaneous dismantling of the junction box and frame using the dismantling structure of the junction box A4 will be described in detail in the third embodiment of the present invention.

[0034] Referring to Figure 1, the position adjustment plate 400 supports the solar module from below. The position adjustment plate 400 supports one side of the module body of the solar module (see A' in Figure 2) from below and is formed to be vertically movable. Referring to Figure 2, the solar module A is positioned so that the rear side where the junction box A4 is located faces upward, and in this state it is mounted on the position adjustment plate 400. Therefore, the surface supported by the position adjustment plate 400 is the surface of the module body A' where the glass plates are arranged, and is the front surface of the solar module (i.e., the light incident surface). The position adjustment plate 400 is vertically movable and connected to the lower support 440, which can be formed of various forms of support structures that support the ground. These support structures can be formed in various forms, such as a form that includes multiple legs. Between the lower support 440 and the position adjustment plate 400, for example, a vertically extending and retracting lifting cylinder 430 is connected, and the position adjustment plate 400 can be raised or lowered by the lifting cylinder 430. However, it is not necessary to be limited to the lifting cylinder 430; it is entirely possible to use other structures that can raise and lower the position adjustment plate 400.

[0035] Referring to Figure 4, an outer support plate 420 may be placed on one side of the position adjustment plate 400. The outer support plate 420 may include a connecting portion 421 extending toward the position adjustment plate 400, and the connecting portion 421 may be detachably connected to the position adjustment plate 400. The outer support plate 420 can be used in a detachable manner as needed. For example, the outer support plate 420 can be placed at the necessary location to reinforce the load applied to the outside of the position adjustment plate 400. However, if the position adjustment plate 400 alone can adequately support the load, the dismantling work can be carried out without using the outer support plate 420.

[0036] Referring to Figure 1, the upper surface of the position adjustment plate 400 (i.e., the surface that contacts the module body of the solar module) may have multiple upwardly projecting elastic parts 410. The elastic parts 410 are made of, for example, natural or artificial rubber material and can be elastically deformed to adhere closely to the contact surface of the module body. Therefore, the module body can be effectively fixed even during dismantling operations. The elastic parts 410 may be formed, for example, in a ring shape and arranged in a form that protrudes from the upper surface of the position adjustment plate 400. However, the elastic parts 410 can be deformed into any other shape, such as a hemisphere. The elastic parts 410 have an appropriate thickness and are elastically deformed vertically by pressure, and by their action can adhere closely to the glass plate of the module body A' (see A1 in Figure 5) and relieve the pressure applied to the glass plate. If necessary, in addition to the elastic parts 410, various structures can be used to increase the friction on the upper surface of the position adjustment plate 400 or to distribute the pressure acting on the upper surface of the position adjustment plate 400.

[0037] An upper contact plate 300 is positioned above the position adjustment plate 400. As shown in Figure 1, the upper contact plate 300 is positioned above the position adjustment plate 400 and opposite to it, and comes into close contact with the other side of the module body when the position adjustment plate 400 rises. The surface to which the upper contact plate 300 comes into contact is the surface on which the junction box A4 of the module body A' protrudes (the surface on which the aforementioned laminated film portion is formed), as shown in Figure 2, and therefore becomes the back surface of the solar module (i.e., the side opposite to the light incident surface). By positioning the upper contact plate 300 and the position adjustment plate 400 opposite each other in the vertical direction, it is possible to firmly fix the module body, which is the internal structure of the solar module, by applying pressure from both the upper and lower surfaces.

[0038] Referring to Figure 3, the upper contact plate 300 can be partially cut. The cut portion can be provided with a space 300a capable of accommodating the junction box A4. For example, if the junction box A4 is located in the center of the solar module A, the corresponding portion of the upper contact plate 300 can be cut to form the space 300a so as not to overlap with the junction box A4. Since the junction box may be located in other positions, if the junction box is located in a position that does not interfere with the upper contact plate 300, it is not necessary to form a space. The upper contact plate 300 is formed to be appropriately small within the range that can pressurize the module body, and space can be secured for the frame separation blade 100 to move inside the frame A3. If necessary, a structure such as the elastic part described above can also be formed on the lower part of the upper contact plate 300.

[0039] Referring to Figure 2, the frame separation blade 100 is positioned on the edge of the upper contact plate 300. Since the frame separation blade 100 is also positioned on the upper part of the position adjustment plate 400, it can be positioned on the edge of the upper contact plate 300 located on the upper part of the position adjustment plate 400. As shown in Figure 2, the frame separation blade 100 can move linearly parallel to the surface of the module body A' between a first position inside the frame A3 and a second position outside the frame A3 (see the solid arrow in Figure 2). The frame separation blades 100 shown in Figure 2 are in a state where they have moved as far back as possible toward the center of the solar module A and are clustered together, which may correspond to the first position of the frame separation blade 100 (i.e., inside the frame). The second position of the frame separation blade 100 may be the position where each frame separation blade 100 moves forward in the direction of the arrow and stops after moving outside the frame A3. Multiple frame separation blades 100 may move at different distances from each other and do not have to move symmetrically. However, in either case, the frame separation blade 100 moves across frame A3 from the inside to the outside, and always intersects with frame A3 surrounding solar module A within the movement section. Therefore, the first position can be understood as the position before intersecting frame A3, and the second position as the position after intersecting frame A3. The first and second positions can be determined relative to frame A3 to which the solar module is coupled.

[0040] As mentioned above, when the position adjustment plate (see 400 in Figure 1) rises, the module body A' comes into close contact with the lower part of the frame separation blade 100 and simultaneously with the upper contact plate 300. Therefore, the module body A' is pressed and fixed between the position adjustment plate 400 and the upper contact plate 300. At this time, the frame A3 protruding from the top and bottom of the edge of the module body A' intersects with the frame separation blade 100 at least partially. Therefore, as shown in Figure 2, when the frame separation blade 100 moves forward from the inside to the outside of the frame A3, it can pressurize the frame A3, and the frame A3 can be dismantled by the pressure. The frame separation blade 100 is made of, for example, a hard metal material, and its blade surface is machined to be sharp.

[0041] In particular, the frame separation blade 100 is composed of a foldable variable blade that is folded or unfolded by the operation of the rotating blade 101 as shown in the figure. The frame separation blade 100 may consist of four blades corresponding to the four sides of the frame A3, and all four of these frame separation blades 100 may be composed of foldable variable blades. Therefore, each frame separation blade 100 is folded as shown in Figure 2 when retracting, and then when advancing, it can come into contact with the frame A3 and make close contact with the entire corresponding side of the frame A3. Thus, it is possible to contact and apply pressure to substantially all parts of the frame A3. A detailed explanation of the structure and movement mechanism of the frame separation blade 100 will be given later.

[0042] The pressurizing drive unit 200 is connected to the frame separation blade 100 and provides driving force to the frame separation blade 100. The pressurizing drive unit 200 includes a plurality of pressurizing cylinders 210, each connected to a plurality of frame separation blades 100, and the pressurizing cylinders 210 move the plurality of frame separation blades 100 forward from the aforementioned first position to the second position. That is, the frame separation blades 100 are moved linearly from the inside to the outside of the frame A3 coupled to the solar module, pressurizing the frame A3 to the outside of the module body A' and dismantling it. As shown in Figure 2, the plurality of frame separation blades 100 are arranged to correspond to each side of the frame A3, and the plurality of pressurizing cylinders 210 can be connected in a direction that intersects each frame separation blade 100 and each side of the frame. The pressurizing cylinders 210 are driven by fluid pressure, and fluid inlet and outlet channels and pumps are appropriately provided around the pressurizing cylinders 210. Equipment related to fluid inlet and outlet is omitted in the drawing. The pressurizing drive unit 200 may include, for example, a main body 201 with a space formed inside, and a pressurizing cylinder 210 may be arranged inside the main body 201. The main body 201 may be arranged in the space on the upper surface of the aforementioned upper contact plate 300, and the upper contact plate 300 and the main body 201 may be molded as a single unit. In this case, structural rigidity may also be improved.

[0043] The structure and operation of the frame separation blade will be described in more detail below with reference to Figures 3 and 4. Figures 3 and 4 are operational diagrams showing the structure and operation of the frame separation blade shown in Figure 2.

[0044] Referring to Figures 3 and 4, the frame separation blade 100 can be connected to each pressurizing cylinder 210 and a connecting block 220. The connecting block 220 includes a head 221 that surrounds and connects to the piston 211 of the pressurizing cylinder 210, and a fixing plate 222 that protrudes from one side of the head 221 and fixes the frame separation blade 100 to the head 221. In particular, the fixing plate 222 recedes from the end of the piston 211 in the longitudinal direction of the piston 211, positioning the frame separation blade 100 inward from the end of the piston 211. In this case, the head 221 surrounding the piston 211 is equivalent to having at least a portion of the head 221 overlapping the piston 211 in the longitudinal direction. The head 221 may be formed in a bracket shape, for example, with its central portion fixed to the end of the piston 211 and both ends bent in the longitudinal direction of the piston 211 to overlap the piston 211. Although the drawing illustrates the head 221 in this shape, it is not limited to this and can be changed to a variety of other shapes.

[0045] The fixing plate 222 protrudes from the head 221 and fixes the frame separation blade 100 to the head 221. The fixing plate 222 is integrated with the head 221 and can be coupled to the frame separation blade 100 in various ways to fix the frame separation blade 100. The fixing plate 222 and the frame separation blade 100 can be coupled using various coupling methods, such as welded coupling, screw coupling, and mating coupling, either individually or in combination thereof. For example, if the head 221 has the bracket shape described above, the fixing plate 222 can be formed on both ends of the bracket bent in the longitudinal direction of the piston 211. This positions the fixing plate 222 away from the ends of the piston 211 and recessed in the longitudinal direction of the piston 211, so that the frame separation blade 100 can be fixed in the same position. Such examples are shown in the drawings.

[0046] Thus, by using the head 221 and the fixing plate 222, the frame separation blade 100 can be positioned longitudinally backward from the end of the piston 211, allowing the position of the frame separation blade 100 to be determined regardless of the stroke or length of the piston 211. In other words, the frame separation blade 100 does not necessarily have to be located outside the end of the piston 211; it may be coupled to the connecting block 220 and positioned inside the end of the piston 211. Therefore, even when using a pressurizing cylinder 210 with a long piston stroke, the position can be adjusted with the connecting block 220 to allow the frame separation blade 100 to reach the inside of the frame as described above. For example, even if the end of the pressurizing cylinder 210 (i.e., the same as the end of the piston) protrudes outside the frame when fully retracted, the head 221 and the fixing plate 222 can be appropriately formed to position the frame separation blade 100 at a first position inside the frame. Therefore, the frame separation blade 100 can be advanced from there to a second position outside the frame to dismantle the frame. By using the connecting block 220 in this way, longer pressurizing cylinders 210 and other devices that can apply greater pressure can be freely used.

[0047] Furthermore, a robust connecting structure consisting of a fixing plate 222 and a head 221 is also formed between the frame separation blade 100 and the pressurizing cylinder 210. The head 221 and the fixing plate 222 may be, for example, integrally molded metal structures, and the end of the piston 211 can be firmly fixed by fastening it with screws or the like after passing through the head 221. In addition, since the fixing plate 222 is joined to the frame separation blade 100 by welding or the like, the connecting structure can have sufficient rigidity to prevent twisting of the frame separation blade 100. Also, as shown in the figure, multiple pressurizing cylinders 210 can be connected in parallel to a single frame separation blade 100, and at least two different support points that support the frame separation blade 100 can be secured, thereby preventing twisting of the frame separation blade 100 and improving structural rigidity. In addition, this is advantageous in increasing the pressure because one side of the frame can be pressurized by multiple pressurizing cylinders 210.

[0048] As described above, the frame separation blade 100 is composed of a foldable variable blade. The foldable variable blade (i.e., the frame separation blade) may include at least two rotating blades 101 that rotate in the forward direction of the frame separation blade 100 in a first position around the axis 103 and fold, and then rotate in the opposite direction and unfold linearly when in contact with the frame. The operation of the rotating blades 101 is illustrated in Figures 3 and 4 (see dotted arrows).

[0049] In other words, the frame separation blade 100 is composed of a foldable variable blade in which the rotating blade 101 rotates around the axis 103 and changes shape. The rotating blade 101 is folded toward the forward direction of the frame separation blade 100 so as not to interfere with other frame separation blades when the frame separation blade 100 is retracted to a first position on the inside of the frame, and then when the frame separation blade 100 moves forward to a second position on the outside of the frame, it is unfolded while rotating in the opposite direction due to pressure while in contact with the frame. As a result, the frame separation blade 100 changes not only in shape but also in length (see Figure 8).

[0050] By using such a variable structure, the length of the frame separation blade 100 can be matched to one side of the frame, allowing for uniform pressure to be applied to the entire frame. For example, when attempting to apply pressure to a frame with a fixed, straight blade, the length must be shortened to prevent overlapping ranges of motion. Consequently, the corners of the frame cannot be pressured, resulting in a problem. In this invention, this problem is solved by the variable structure of the frame separation blade 100 (i.e., a foldable variable blade) (see Figures 7 and 8).

[0051] If necessary, a torsion spring (or a twist spring - not shown) can be attached to the shaft 103 to form the rotating blade 101 so that it elastically folds in the forward direction. In this case, the rotating blade 101 can be deployed by the pressure applied by the frame when it comes into contact with the frame, and automatically folded by the elasticity of the torsion spring when it retracts. Thus, when the frame separation blade 100 retracts to the first position, it can be more easily gathered inside the frame while automatically folding.

[0052] The foldable variable blade (i.e., frame separation blade) may further include a central fixed blade 102 positioned between two rotating blades 101 and connected to each rotating blade 101 by an axis 103. That is, as shown in Figures 3 and 4, the frame separation blade 100 can be formed in a structure in which two rotating blades 101 are rotatably connected to both ends of the central fixed blade 102 via an axis 103. In this case, the frame separation blade 100 is a variable structure including at least two axes 103. However, there may be one axis 103 (see Figure 10) or two or more. The variable structure can be deformed in various forms including axes. Since the axis 103 is formed to rotate the rotating blades 101 on the same plane as the blade surface of the frame separation blade 100, the axis (not shown) passing through the center of rotation is positioned perpendicular to the blade surface of the frame separation blade 100. The axis 103 can be formed, for example, as a hinge axis composed of a hinge. In this manner, the variable structure of the frame separation blade 100 can be formed.

[0053] The aforementioned fixing plate 222 can be coupled to the central fixing blade 102 of the frame separation blade 100. That is, the fixing plate 222 can be coupled to the central fixing blade 102, and the frame separation blade 100 can be connected and fixed to the pressurizing cylinder 210 via the connecting block 220. However, it is not necessarily limited to this, and for example, even if it is not the central fixing blade 102, it is entirely possible to connect the frame separation blade 100 and the pressurizing cylinder 210 by extending or deforming a part of the structure around the shaft 103 (i.e., a part located at the rotation center of the rotating blade that does not actually rotate) so that it can be coupled to the fixing plate 222, for example, to form another form of fixing part and coupling the fixing part with the fixing plate 222.

[0054] A rotation limiting portion 104 may be formed on one side of the rotating blade 101 to limit the maximum rotation angle of the rotating blade 101. The rotation limiting portion 104 adjusts the rotation range of the rotating blade 101 to fix the blade surface of the rotating blade 101 in a state parallel to the frame. For example, the rotation limiting portion 104 may be formed as a structure that prevents rotation beyond a predetermined angle by providing a cut portion cut at a predetermined angle at the end of the rotating blade 101 adjacent to the shaft 103. In this case, the rotation limiting portion 104 can limit the maximum rotation angle of the rotating blade 101 according to the cut angle of the cut portion, and after the rotating blade 101 has rotated by a predetermined angle, it can be fixed in a linear shape as a whole (see Figures 8 and 9).

[0055] If necessary, the rotation limiting portion 104 may also be formed at the end of the central fixed blade 102 adjacent to the shaft 103. In this case, it may include structures such as a flat surface or protrusion that contacts the cutting portion formed at the end of the central fixed blade 102. In other words, the rotation limiting portion 104 can be formed with a variety of structures that can contact and prevent rotation when the rotating blade 101 rotates by a predetermined angle. The structure of the rotation limiting portion 104 is not limited as long as it can limit or adjust the maximum rotation angle of the rotating blade 101.

[0056] The frame separation blade 100, which is composed of foldable variable blades in this manner, when unfolded in a straight line, has an overall length that substantially matches the length of the corresponding side of the frame (see Figure 8). That is, when folded as shown in Figures 3 and 4, the length between the two ends is shorter, but when unfolded and in contact with the frame, its length extends to the same length as one side of the frame, and it makes complete contact with the entire side of the frame. Therefore, the entire frame can be uniformly pressed while making contact with the corners of the frame.

[0057] The following section will describe in more detail the frame dismantling operation using the variable structure of the frame separation blade described above.

[0058] Figure 5 shows the position adjustment operation of the solar module in the solar module casing dismantling device of Figure 1, Figure 6 is a plan view showing the arrangement of the frame separation blade and pressurizing drive unit in the solar module casing dismantling device of Figure 5, Figure 7 is an arrangement diagram showing only the frame separation blade separately from the plan view of Figure 6, and Figures 8 and 9 are operation diagrams showing the frame separation process using the variable movement of the frame separation blade of Figure 7. Figure 5 is a cross-section to show the internal structure of the solar module casing dismantling device, and Figure 6 shows the cross-section a-a' in Figure 5 with the rail 600 omitted.

[0059] Referring to Figure 5, the solar module exterior dismantling device 1 can automatically receive and dismantle solar modules A via rails 600 or the like. The rails 600 can be installed in an appropriate position, for example, so that their ends face the upper end of the lower support 440. The height of the rails 600 is adjusted to match the height of the upper end of the position adjustment plate 400 when lowering. Multiple rails 600 can be provided, such as a rail 600 for supplying solar modules A (the rail located on the right side of Figure 5) and a rail 600 for discharging the module body A' after the frame A3 has been dismantled (the rail located on the left side of Figure 5). The rails 600 may be equipped with a transport structure such as rollers or belts capable of transporting solar modules A.

[0060] The supplied solar module A is mounted on the position adjustment plate 400, which raises it. As a result, solar module A rises and comes into close contact with the superstructure, as shown in Figure 5. As mentioned above, since the upper contact plate 300 is positioned above the position adjustment plate 400, the module body A', which is the inner structure of solar module A, is fixed in close contact between the position adjustment plate 400 and the upper contact plate 300. At this time, the frame separation blades 100 positioned on the edge of the upper contact plate 300 also come into close contact with the module body A' and, as shown in Figure 5, at least partially intersect with the frame A3 surrounding the module body A'. In the state shown in Figure 5, all of the frame separation blades 100 are in the first position inside the frame A3.

[0061] At this time, the junction box A4 protruding from the upper surface of the module body A' is inserted into an empty space such as the aforementioned space (see 300a in Figure 3) so as not to interfere with other structures. If necessary, the junction box may be removed first, but as will be described later, it is also possible to dismantle it simultaneously with the frame A3 using the junction box separation blade of the present invention (see 110 in Figure 16). The dismantling of the junction box will be described in detail in the third embodiment of the present invention.

[0062] In this process, the upper contact plate 300 is subjected to pressure from below, but this can be supported by a support structure such as an upper support column 310. That is, an upper support column 310 may be provided, which is vertically connected to the upper surface of the upper contact plate 300 and supports the pressure applied to the lower part of the upper contact plate 300 at the top. The lower end of the upper support column 310 may be connected to the upper contact plate 300, and the upper end may be connected to an upper support body 320 or the like that provides support force. The upper support body 320 can support the ground, and its structure and form do not need to be particularly limited, so specific shapes and other details are omitted and it is illustrated simply. The upper support body 320 can be formed into various shapes that can support the upper structure including the upper contact plate 300, the pressurizing drive unit 200 placed on it, and the frame separation blade 100 connected to the pressurizing drive unit 200. In the drawing, the upper support body 320 is shown as a structure that supports the ground, but if necessary, the upper support body 320 may also be supported by the ceiling of the workspace or the like.

[0063] As shown in Figure 5, once the solar module A is fixed, the frame separation blades 100 are positioned inside frame A3 in a foldable state, as shown in Figure 6. That is, the multiple frame separation blades 100, which are composed of foldable variable blades, gather together in a folded state inside frame A3 at the first position. The frame separation blades 100 can retract in advance before the aforementioned position adjustment plate 400 rises, and gather together inward as shown in Figure 6. During the retraction process, the rotating blades 101 fold while rotating in the forward direction, so that, as shown in Figure 6, at least a portion of the frame separation blades 100 are folded and mutual interference is eliminated at the first position.

[0064] Figure 7 shows this arrangement of frame separation blades 100 more clearly. Figures 7 through 9 are illustrated with other structures arbitrarily omitted to further illustrate the deformation operation of the frame separation blades 100. The arrangement of frame separation blades 100 in Figure 7 is illustrative, and the frame separation blades 100 can also converge further toward the center of the solar panel A within the range of movement when retracting inward into the frame. In this way, even when the frame separation blades 100 move in directions that intersect each other, at least a portion of the blades are folded by the foldable variable structure, so they do not interfere with each other even in the first position inside frame A3.

[0065] In this state, when the pressurizing cylinder (see 210 in Figure 6) is driven, each frame separation blade 100 moves from a first position inside frame A3 to a second position outside frame A3. Figure 7 is an example of the first position of the frame separation blade 100, and Figure 9 is an example of the second position of the frame separation blade 100. Figure 8 illustrates an intermediate position in which the frame separation blade 100 has advanced to the second position and is in contact with frame A3 and deployed.

[0066] As shown in Figure 8, each frame separation blade 100, as it moves forward toward the second position, unfolds along each side of frame A3 by its variable structure, and comes into close contact with each of the four sides of frame A3. The rotating blade 101 unfolds linearly while rotating in the opposite direction of forward movement in contact with frame A3. Therefore, as shown in the figure, the length of both ends of the frame separation blade 100 increases, and it comes into substantially close contact with all four sides of frame A3 without any gaps.

[0067] Referring to the enlarged views of Figures 7 and 8, the end of the rotating blade 101 slides linearly from the inside to the outside of frame A3 while in close contact with frame A3, reaching the corner of frame A3 (see the enlarged view of Figure 7). Therefore, when the frame separation blade 100 is deployed in contact with frame A3, the end of the rotating blade 101 contacts the corner of frame A3 and presses against it (see the enlarged view of Figure 8). The corner corresponds to the vertex where two sides of frame A3 intersect, and conventional blades are forced to shorten their length to avoid interference on the inside of frame A3 (first position), making it practically impossible to press against the corner. However, the present invention solves this problem with a foldable variable structure (foldable variable blade) of the frame separation blade 100, which changes its shape and length by rotating the rotating blade 101.

[0068] In the deployed state shown in Figure 8, the rotation blade 101 is restricted from further rotation by the aforementioned rotation limiting section 104. Therefore, the blade surface is fixed parallel to the frame A3. Since the central fixed blade 102 also has its blade surface positioned parallel to the frame A3, in the deployed state, the frame separation blade 100 consists of the two rotation blades 101 and the central fixed blade 102 between them, all aligned in a straight line and in close contact with the entire side of the frame A3 without any gaps. Therefore, each frame separation blade 100 can apply uniform pressure to all parts of the frame A3, including the corners. This reduces unnecessary deformation and unintended damage to the frame A3 due to pressure imbalances, and allows for more effective dismantling of the frame A3 by applying pressure to the corners.

[0069] For example, as shown in Figure 9, the frame separation blade 100 can advance to the second position and press down on all four sides of frame A3 without any gaps, thereby separating frame A3 side by side. In the case of a typical rectangular frame A3, the corners are often joined together, so pressing down on the corners makes separation easier. However, as mentioned above, conventional blades are short in length to avoid interfering with the inside, which makes it difficult to press down on the corners. The present invention is more effective when dismantling a rectangular frame with corners because the rotating blade 101 can be deployed to press down on all corners of frame A3 without any gaps. In this way, frame A3 can be effectively dismantled using the frame separation blade 100, which is composed of a foldable variable blade.

[0070] Figure 10 is a plan view showing a modified example of the frame separation blade shown in Figure 7.

[0071] On the other hand, the variable structure of the frame separation blade 100 can also be transformed into other forms. For example, as shown in Figure 10, at least one of the frame separation blades 100 can be composed of only the rotating blade 101. That is, two rotating blades 101 can be directly connected around the axis 103 to form a foldable variable blade. In this case, as described above, a part of the structure around the axis 103 (i.e., the part located at the rotation center of the rotating blade and not actually rotating) can be extended or transformed to form another form of fixed part so as to be connectable with the aforementioned fixed plate (see 222 in Figure 3), and the frame separation blade 100 and the pressurizing cylinder (see 210 in Figure 3) can be connected by methods such as connecting the fixed part and the fixed plate.

[0072] Such a deformable structure for the frame separation blade 100 can be applied according to various requirements. When the frame separation blade 100 is deformed, the range of movement of the frame separation blade 100, the rotation angle of the rotating blade 101, and the movement method can also be appropriately changed accordingly. For example, the frame separation blade 100 can be transformed into a foldable variable blade form according to the size and specifications of the solar panel. As mentioned above, it is composed of a foldable variable blade including a rotating blade 101, and the length when unfolded, the arrangement of the axes, the thickness of the blade, and the rotation angle of the rotating blade 101 can be deformed and applied in a form that can more effectively pressurize the frame depending on the situation. In this way, a frame separation blade 100 composed of a foldable variable blade can be formed in various ways, and the frame of the solar panel can be effectively dismantled.

[0073] In the following, a second embodiment of the present invention will be described in detail with reference to Figures 11 to 14. For the sake of brevity and clarity, the description will focus on the differences from the previously described embodiment, and all other configurations not specifically mentioned will be described in the previous description.

[0074] Figure 11 is a plan view illustrating the arrangement of the grippers in a solar module exterior dismantling device according to a second embodiment of the present invention, and Figure 12 is a perspective view showing the grippers in Figure 11. In Figure 11, other structures are arbitrarily omitted in order to show the arrangement of the frame separation blades and the grippers.

[0075] Referring to Figures 11 and 12, a solar module casing dismantling device according to a second embodiment of the present invention may further include a gripper 500 coupled to a frame separation blade 100. The other configurations are substantially the same as those of the previously described embodiments and will not be repeated. The gripper 500 may include a movable claw 510 coupled to the frame separation blade 100, which grips the frame of the solar module and brings it into close contact with the frame separation blade 100 (see Figure 12). The movable claw 510 is capable of folding or unfolding and may, for example, be structured to rotate around a fixed axis. The movable claw 510 may be coupled to a fixed axis 511 at one end, which is fixed to the frame separation blade 100, and may rotate around the fixed axis 511 to fold or unfold. In Figure 12, the movable claw 510 may be in the unfolded state, and when folded by rotating around the fixed axis 511, the frame can be accommodated between the frame separation blade 100 and the movable claw 510.

[0076] The gripper 500 is provided, for example, on the central fixed blade 102 of the frame separating blade 100, as shown in Figure 11. However, it is not limited to this, and it is perfectly possible to place it on the rotating blade 101 or other locations as needed. Figure 11 simply shows the possible locations where the gripper 500 can be installed in this embodiment.

[0077] Referring to Figure 12, the fixed shaft 511 may be provided on a fixed structure fixed to the frame separation blade 100, such as a receiving portion 550. One end of the movable claw 510 is rotatably coupled to the fixed shaft 511, and the other end may be formed in a bent shape. The movable claw 510 may include a hinge shaft 531 on one side that is separated from the fixed shaft 511, and driving force can be transmitted via the hinge shaft 531. An operating cylinder 520, which is operated by fluid pressure, is connected to the hinge shaft 531, and the movable claw 510 can be operated by driving the operating cylinder 520. Although not shown, a fluid passage for entering and exiting may be formed on one side of the operating cylinder 520, and a pump or other connected thereto may be placed in an appropriate position.

[0078] The structure of the gripper 500 can be described in more detail as follows: The gripper 500 may include a sensor unit 540 that senses the frame on one side of the frame separation blade 100 and generates a sensing signal, and the aforementioned operating cylinder 520 which is hinged to a hinge shaft 531 located on the movable claw 510, separated from the fixed shaft 511, and drives the movable claw 510 by pushing and pulling the hinge shaft 531 with fluid pressure in response to the sensing signal. Thus, the gripper 500 can automatically grip the frame by the sensing operation of the sensor unit 540. The operating cylinder 520 includes an extendable piston and may be coupled to the hinge shaft 531 by forming a connecting link 530 as shown at the end of the piston. The connecting link 530 may function as a kind of joint connecting the operating cylinder 520 and the movable claw 510, with one end coupled to the hinge shaft 531 and the other end coupled to a connecting shaft 532 at the piston end.

[0079] The sensor unit 540 may include a contact sensor for detecting contact with an object, and may also include other sensors as needed, such as a proximity sensor for detecting an object approaching within a predetermined range. The sensor unit 540 can be configured in various ways to detect the frame. The sensor unit 540 can be electrically connected to a control unit (for example, a control structure including an electronically controlled pump for adjusting hydraulic pressure) that controls the operating cylinder 520, and transmit signals, thereby automatically operating the operating cylinder 520. With this configuration, the frame can be gripped and fixed, and dismantled more safely as follows.

[0080] Figures 13 and 14 are operational diagrams showing the operation of the gripper in Figure 12.

[0081] The gripper 500 can be maintained in the state shown in Figure 13 before the sensor unit 540 detects frame A3. That is, the operating cylinder 520 retracts and pulls the hinge shaft 531, and the movable claw 510 is maintained in the deployed state. If frame A3 is not detected even when the frame separation blade 100 on which the gripper 500 is mounted moves, the gripper 500 maintains that state. However, as shown in Figure 14, when the sensor unit 540 detects an adjacent frame A3 by contact or other means, the operating cylinder 520 pushes the hinge shaft 531 and quickly rotates the movable claw 510. As a result, the movable claw 510 folds and grips frame A3, and frame A3 is held between the frame separation blade 100 and the movable claw 510. Therefore, accidents such as frame A3 flying outward due to the pressure applied by the frame separation blade 100 can be effectively prevented. As a result of the aforementioned dismantling operation of frame A3 (see Figures 7 to 9), when module body A' detaches from frame A3, the movable claw 510 expands its range of rotation and can be folded further. This allows frame A3 to be fixed more securely.

[0082] In this configuration, the connecting link 530 is a kind of double joint structure including a hinge shaft 531 and a connecting shaft 532, which can flexibly convert the linear motion of the piston into the rotational motion of the movable claw 510. Furthermore, since the shape of the movable claw 510 is not limited, it can be freely transformed into a form different from that shown in the drawing. If necessary, the degree of bending of the ends, the shape, the overall length, etc. can be appropriately changed to fix the frame A3 more firmly. Such grippers 500 can be coupled to multiple different frame separation blades 100, as shown in Figure 11. Therefore, multiple pieces of frame A3 separated from each other can be gripped and fixed by multiple grippers 500. Thus, even when applying stronger pressure with a pressurizing cylinder 210 having a relatively long stroke, the dismantling process can be carried out very safely. The number of grippers 500 placed on the frame separation blade 100 can be one or more, and can be increased or decreased as needed, and the position of the grippers 500 can also be freely changed, so it is possible to properly install the grippers 500 and carry out dismantling work more safely. This method allows for safer dismantling of the frame by applying the gripper 500 to the frame separation blade 100.

[0083] In the following, a third embodiment of the present invention will be described in detail with reference to Figures 15 and 16. For the sake of brevity and clarity, the description will focus on the differences from the previously described embodiments, and all other configurations not specifically mentioned will be described in the previous explanation.

[0084] Figure 15 is a plan view showing the junction box separation blade of a solar module exterior dismantling device according to a third embodiment of the present invention, and Figure 16 is an operation diagram of the junction box separation blade of Figure 15. In Figures 15 and 16, other structures have been arbitrarily omitted to show the arrangement of the frame separation blade and the junction box separation blade.

[0085] Referring to Figures 15 and 16, the solar panel exterior dismantling device according to the third embodiment of the present invention may include a junction box separation blade 110 positioned on at least one of the frame separation blades 100. The aforementioned junction box A4 can be dismantled together with the frame A3 using the junction box separation blade 110.

[0086] Referring to Figure 15, the junction box separation blade 110 may be formed to protrude from the frame separation blade 100. The junction box separation blade 110 may also be formed such that a part of the frame separation blade 100 protrudes rearward in the forward direction, and at least one junction box dismantling groove 111 is formed inside into which the junction box A4 is inserted. The junction box separation blade 110 can dismantle the junction box A4 by moving with the junction box A4 housed in the junction box dismantling groove 111.

[0087] The junction box separation blade 110 may, for example, protrude from the central fixed blade 102 of the frame separation blade 100. The junction box separation blade 110 and the central fixed blade 102 may be formed integrally with each other. Therefore, the frame separation blade 100 and the junction box separation blade 110 can move simultaneously in the same direction.

[0088] The junction box separation blade 110 may extend, for example, towards the space between the upper contact plates (see 300a in Figure 3). As mentioned above, the junction box A4 is also located in this space, so the junction box A4 can be easily inserted into the junction box dismantling groove 111 formed in the junction box separation blade 110. For example, when the position adjustment plate (see 400 in Figure 5) rises, the junction box A4 can be inserted into the junction box dismantling groove 111.

[0089] The location of the junction box A4 may vary depending on the type of solar panel. The junction box separation blade 110 of this embodiment is particularly advantageous for dismantling junction box A4 located in the inner central part of frame A3. Since the junction box separation blade 110 protrudes rearward (i.e., backward) in the forward direction of the frame separation blade 100, it can be used to process junction box A4 located in the backward direction of the frame separation blade 100 (e.g., in the inner central part of the frame). The junction box dismantling groove 111 may be formed through the junction box separation blade 110.

[0090] The junction box separation blade 110 has multiple junction box dismantling grooves 111, and can selectively accommodate junction boxes A4 at different positions. The junction box dismantling grooves 111 are formed in a shape corresponding to the junction box and may be formed in a polygonal shape such as a rectangle. At least one blade surface can be positioned on the inner surface of the junction box dismantling groove 111 to contact the junction box A4.

[0091] With this structure, the junction box A4 is pressurized and separated by the junction box separation blade 110 when the frame separation blade 100 moves, as shown in Figure 16. Since the junction box A4 is housed in the junction box dismantling groove 111, it receives pressure in the direction of movement of the junction box separation blade 110 when the junction box separation blade 110 moves, and is dismantled simultaneously with the frame A3. After dismantling, for example, the aforementioned position adjustment plate (see 400 in Figure 5) can be lowered to discharge the junction box A4, and by adjusting the stroke of the pressurizing cylinder to advance the frame separation blade 100 sufficiently outward, the junction box dismantling groove 111 can be exposed to the outside of the module body A' and the junction box A4 can be discharged. With this method, the junction box separation blade 110 is formed on the frame separation blade 100, and the frame and junction box can be dismantled simultaneously.

[0092] While embodiments of the present invention have been described above with reference to the attached drawings, any person with ordinary skill in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without altering its technical idea or essential features. Therefore, the above embodiments are merely illustrative in all respects and should not be interpreted as limiting. [Explanation of Symbols]
