Description

Technology Field

[0001] The present invention relates to an automated surface peeling device for waste solar modules utilizing high-temperature, high-pressure air, and more specifically, to an automated surface peeling device for waste solar modules utilizing high-temperature, high-pressure air that can increase peeling efficiency and prevent damage to the tempered glass by locally spraying high-temperature, high-pressure air at the point where the solar cell is peeled off when separating tempered glass and solar cells from a panel (hereinafter referred to as a 'laminated panel') from which an aluminum frame has been removed from a waste solar module. Background Technology

[0003] With the recent spread of carbon neutrality policies and the growing need for new and renewable energy, the installation of solar power generation facilities is rapidly increasing worldwide.

[0004] Generally, the lifespan of a solar module is about 20 to 30 years, and as the time comes to discard the solar modules that were installed intensively in the early 2000s, the amount of discarded solar modules is expected to increase rapidly.

[0005] Waste solar modules consist mostly of components such as tempered glass, aluminum frames, and solar cells bonded with ethylene-vinyl acetate (EVA) sheets, and also contain valuable metals with high recycling value.

[0006] In the process of recycling these waste solar modules, a key step requires technology to first physically dismantle the aluminum frame surrounding the module and then separate the tempered glass from the remaining panel (a laminate of tempered glass and solar cells).

[0007] As an example of such tempered glass separation technology, Registered Patent No. 10-2091346 (hereinafter referred to as 'prior art') has been disclosed.

[0008] The prior art adopts a 'total preheating' method in which a 'heating unit' is positioned at the bottom of the transport unit to preheat the entire solar panel being transported during the transport process.

[0009] This is to heat the adhesive layer (EVA) between the panel and the tempered glass above its melting point.

[0010] Subsequently, the prior art utilizes a two-stage mechanical peeling section. That is, the peeling is performed by a method in which a ‘first peeling section’ at the top of a preheated panel scrapes off a portion of the cell portion using a plurality of blades, and another blade provided in the ‘second peeling section’ at the rear contacts the surface of the exposed tempered glass directly and scrapes off the remaining cell portion with mechanical force.

[0011] However, this prior art uses a method of heating the entire panel to the melting point of the adhesive, not just the narrow line area where actual peeling occurs.

[0012] This involves heating areas that are unnecessary for the process, which consumes a massive amount of energy and presents an inefficient problem that reduces the economic viability of the recycling process.

[0013] In addition, the prior art relies entirely on a method in which the blade of the 'second peeling section' directly contacts the surface of the tempered glass and scrapes it off with mechanical force.

[0014] This mechanical scraping method carries a constant risk of causing fine scratches or cracks on the surface of tempered glass during the process, which is pointed out as a fundamental limitation that degrades the quality of recycled glass and increases the possibility of glass breakage.

[0015] In addition, the prior art had limitations in that it did not disclose a configuration for precisely trimming the edges of the panel in advance to increase the precision of the peeling process, or a specific system for rapidly and automatically discharging separated cell residue (roll sheet) to the side of the process line after the peeling is completed. Prior art literature

[0017] Registered Patent No. 10-2091346 The problem to be solved

[0018] The present invention was developed to improve upon the aforementioned problems and aims to provide an automated surface peeling device for waste solar modules utilizing high-temperature, high-pressure air, which maximizes energy efficiency and fundamentally prevents damage to tempered glass by locally spraying high-temperature, high-pressure air only at the point where peeling occurs, without heating the entire panel, during the process of transporting panels from which aluminum frames have been removed from waste solar modules.

[0019] Furthermore, the present invention is intended to provide an automated surface peeling device for waste solar modules utilizing high-temperature, high-pressure air, comprising a panel trimming section including a sanding wheel that precisely grinds the edges of the panel before a hot knife enters, in order to ensure the precision and stability of the peeling process.

[0020] In addition, the present invention provides an automated surface peeling device for waste solar modules utilizing high-temperature, high-pressure air, which enhances the stability of the automated process by providing a panel moving pusher that stably transports a panel from which an aluminum frame has been removed into a process frame, and a panel fixing cylinder that firmly fixes the panel to prevent the panel from detaching during the trimming process.

[0021] In addition, the present invention provides an automated surface peeling device for waste solar modules utilizing high-temperature, high-pressure air, which increases process efficiency by providing an automated roll sheet discharge unit that rapidly and accurately discharges a roll sheet wound into a roll shape to the side (second direction) of the process line after the peeling process is completed.

[0022] Furthermore, the present invention provides an automated surface peeling device for waste solar modules utilizing high-temperature, high-pressure air, which provides a separate panel discharge unit that safely transports and discharges the remaining glass panels from which the roll sheets have been removed to the exit side of the process frame, thereby ensuring that the final output is automatically separated and discharged without mixing. means of solving the problem

[0024] To achieve the above objective, the present invention provides an automated surface peeling device for waste solar modules utilizing high-temperature, high-pressure air, characterized by comprising: a process frame in which a process is sequentially performed in which a panel (hereinafter referred to as a laminate panel) from which an aluminum frame has been removed from a waste solar module is transported along a first direction, a solar cell is peeled from the laminate panel and wound into a roll shape, and the rolled sheet of the roll shape is discharged in a second direction perpendicular to the first direction; and a hot air injection unit disposed between the inlet side of the process frame and the outlet side of the process frame, which sprays localized high-temperature, high-pressure air along the point where the solar cell is peeled from the laminate panel in the second direction.

[0025] Here, the process frame comprises: a panel mounting table in which a plurality of flat table panels are arranged parallelly along the first direction to form an upper surface; at least one first support column protruding along a third direction simultaneously perpendicular to the first direction and the second direction on the outer edges of both sides of the other end of the panel mounting table, with respect to one end of the panel mounting table forming the inlet side of the process frame; a first support frame including a first connecting body formed along the second direction and interconnecting the upper ends of each of the at least one first support column; a base having an upper surface facing the lower surface of the other end of the panel mounting table, wherein the upper surface on which the hot air injection unit is installed extends along the first direction; at least one second support column protruding along the third direction on the outer edges of both sides of the other end of the upper surface of the base forming the outlet side of the process frame, with respect to one end of the upper surface of the base facing the lower surface of the other end of the panel mounting table; and a first connecting body formed along the second direction and interconnecting the upper ends of each of the at least one second support column. The invention is characterized by comprising a second support frame including a second connecting body formed therein, at least one third support column protruding along the third direction on the outer sides of the upper surface of the base and disposed between the first support column and the second support column, and a third support frame including a third connecting body formed along the second direction that interconnects the upper ends of each of the at least one third support column, wherein the hot air injection unit is formed on one side of the third support frame, one end of the panel mounting table forms the inlet side of the process frame, and the other end of the upper surface of the base forms the outlet side of the process frame.

[0026] At this time, the panel moving pusher further includes a moving body positioned at the lower part of the panel mounting table, which moves along the first direction and transfers the laminated panel mounted on the panel mounting table to the hot air injection unit side, wherein the moving body is positioned at one end of the panel mounting table before the laminated panel is mounted on the upper surface of the panel mounting table, and when the laminated panel is mounted on the upper surface of the panel mounting table, moves together with the laminated panel to the other end of the panel mounting table, and then returns to the one end of the panel mounting table before a newly introduced laminated panel is mounted on the panel mounting table.

[0027] In addition, it is characterized by further including at least one panel fixing cylinder formed elastically on one side of the first connecting body and extending downward along the third direction when the laminate panel, which has been transported along the first direction from the inlet side of the process frame, is detected on the lower surface of the first connecting body, and a panel fixing bar coupled to the lower end of a fixing rod that is accessible from the panel fixing cylinder and extending along the second direction.

[0028] In addition, it is characterized by further including a panel trimming part provided on one side of the first connecting body, which is adjustable in height along the third direction and moves along the second direction to trim the edge of the laminate panel.

[0029] In addition, the panel trimming unit comprises a horizontal driving body capable of reciprocating along the second direction by receiving driving force on the upper surface of the first connecting body, a vertical driving body mounted on one side of the horizontal driving body capable of adjusting its height position along the third direction by receiving driving force, and a sanding wheel coupled to the vertical driving body that trims the edge of the laminate panel while rotating by receiving driving force.

[0030] In addition, the hot air injection unit is formed between the third support frame and the second support frame.

[0031] In addition, it further comprises a roll sheet discharge unit formed on the third support frame and disposed between the third support frame and the second support frame, capable of reciprocating along the second direction, and discharges a roll sheet formed by winding a solar cell, which is peeled from the laminate panel by the peeling blade of the hot air injection unit, into a roll shape along the second direction.

[0032] In addition, it is characterized by further including a panel discharge unit formed in the second connecting body, which discharges a glass panel along the first direction from which a roll sheet formed by a solar cell peeled from and wound from the laminate panel has been removed.

[0033] In addition, the panel discharge unit is characterized by including a second roller lifting cylinder installed on the upper surface of the second connecting body, and a pair of second panel transfer rollers arranged vertically with both ends rotatably supported along a second direction between the lower surface of the second connecting body and the upper surface of the base, having outer surfaces facing each other. Effects of the invention

[0035] According to the present invention with the above-described configuration, the following effects can be achieved.

[0036] First of all, unlike prior art that preheats the entire panel, the present invention has the advantage of significantly reducing the energy required to melt the adhesive layer by locally spraying high-temperature, high-pressure air with a hot air injection unit only at the point where peeling occurs, thereby greatly improving the economic efficiency of the entire recycling process.

[0037] In addition, the present invention adopts a method in which a hot knife assists in cutting after the adhesive layer is sufficiently melted by high-temperature hot air. Unlike the method of the prior art in which a blade directly scrapes the surface of the tempered glass, this method does not cause any scratches or damage to the surface of the tempered glass, thus having the advantage of enabling the recovery of high-quality recycled glass.

[0038] In addition, the present invention has the advantage of improving the stability and precision of the entire process by providing a panel trimming unit including a sanding wheel at the front of the peeling process, thereby precisely grinding and tidying the edges of the panel into which the hot knife enters, and ensuring that the hot knife always enters at the correct position.

[0039] In addition, the present invention has the distinctive advantage of implementing a continuous, fully automated process without operator intervention, from panel feeding, trimming, and peeling to the separation and discharge of the final product, including roll sheets and glass panels, by organically linking automation units such as a panel moving pusher, a panel fixing cylinder, a roll sheet discharge unit, and a panel discharge unit.

[0040] Furthermore, the present invention has the advantage of maximizing process efficiency and workability by automatically and perfectly separating and discharging the final output without the peeled roll sheet being discharged to the side of the process line through the roll sheet discharge section and the separated glass panel being discharged to the end of the process line through the panel discharge section.

[0071] The present invention may apply an embodiment having a structure including a process frame (100) and a hot air injection unit (200) as shown in FIG. 1.

[0072] First, the process frame (100) forms a path in which a panel (hereinafter referred to as a laminate panel (800)) from which an aluminum frame has been removed from a waste solar module is transported along a first direction, and a process is sequentially performed in which a solar cell (hereinafter not shown) is peeled off from the laminate panel (800) and wound into a roll shape, and the wound roll-shaped roll sheet (802, hereinafter referred to as FIG. 3) is discharged in a second direction orthogonal to the first direction.

[0073] And, the hot air injection unit (200) is positioned between the inlet side (101, see FIG. 1 below) of the process frame (100) and the outlet side (102, see FIG. 1 below) of the process frame (100) to inject local high-temperature, high-pressure air in a second direction along the point where the solar cell is peeled off from the laminate panel (800).

[0074] The present invention is applicable to the above-described embodiments, and it goes without saying that it is also applicable to various embodiments as follows.

[0076] First, the process frame (100) may include a panel mounting table (140) in which a plurality of flat table panels (141) are arranged parallel along a first direction to form an upper surface, as shown in FIGS. 2 and 3.

[0077] And, the process frame (100) may include a first support frame (110) comprising at least one first support column (111) formed protruding along a third direction perpendicular to both the first and second directions on the outer edges of the other end of the panel mounting table (140) with respect to the end of the panel mounting table (140) forming the inlet side (101) of the process frame (100), and a first connecting body (112) formed along the second direction that interconnects the upper ends of each of the at least one first support column (111).

[0078] And, the process frame (100) has an upper surface facing the lower surface of the other end of the panel mounting table (140), and the upper surface where the hot air injection unit (200) is installed may include a base (150) extending along the first direction.

[0079] And, the process frame (100) may include a second support frame (120) comprising at least one second support column (121) protruding along a third direction on the outer sides of the upper end of the base (150) that forms the exit side (102) of the process frame (100) with respect to the lower end of the other end of the panel mounting table (140) facing the upper end of the base (150), and a second connecting body (122) formed along a second direction that interconnects the upper ends of each of the at least one second support column (121).

[0080] Additionally, the process frame (100) may include a third support frame (130) comprising at least one third support column (131) protruding along a third direction on the outer sides of the upper surface of the base (150) and positioned between the first support column (111) and the second support column (121), and a third connecting body (132) formed along a second direction that interconnects the upper ends of each of the at least one third support column (131).

[0081] Here, it can be seen that the hot air injection unit (200) is formed on one side of the third support frame (130), one end of the panel mounting table (140) forms the inlet side (101) of the process frame (100), and the other end of the upper surface of the base (150) forms the outlet side (102) of the process frame (100).

[0083] Meanwhile, the automated surface peeling device for waste solar modules using high-temperature, high-pressure air according to a preferred embodiment of the present invention may further include a panel moving pusher (300) comprising a moving body (310) that is positioned at the bottom of a panel mounting table (140) as shown in FIGS. 4 and 5, moves along a first direction, and transfers a laminated panel (800) mounted on the panel mounting table (140) to the hot air injection unit (200).

[0084] Here, the movable body (310) can be positioned at one end of the panel mounting table (140) before the laminate panel (800) is mounted on the upper surface of the panel mounting table (140).

[0085] At this time, it can also be observed that when the laminate panel (800) is mounted on the upper surface of the panel mounting table (140), it moves together with the laminate panel (800) to the other end of the panel mounting table (140), and then returns to the end of the panel mounting table (140) before the newly introduced laminate panel (800) is mounted on the panel mounting table (140).

[0087] Meanwhile, the panel moving pusher (300) may include a moving support table (301) formed along a first direction on the lower part of the panel mounting table (140) and having an upper surface facing the lower surface of the panel mounting table (140), and a first LM guide (302) formed along a first direction on the upper surface of the moving support table (301).

[0088] And, the panel moving pusher (300) may include a moving body (310) that reciprocates along a first LM guide (302) and a support bar (320) that protrudes from one side of the moving body (310).

[0089] And, the panel moving pusher (300) may include a pusher bar (330) that passes between the table panels (141) constituting the panel mounting table (140), is coupled to the upper end of a support bar (320) exposed from the upper surface of the panel mounting table (140), extends along a second direction, reciprocates in conjunction with the support bar (320) and the moving body (310), and moves the laminated panel (800) by pushing one edge of the laminated panel (800) mounted on the upper surface of the panel mounting table (140) toward the exit side (102) of the process frame (100) and transporting the laminated panel (800).

[0090] Additionally, the panel moving pusher (300) may include a plurality of panel detection sensors (340) mounted on one side of the pusher bar (330) and spaced apart along a second direction to detect one edge of a laminate panel (800) mounted on the upper surface of the panel mounting table (140).

[0091] Accordingly, as the pusher bar (330) begins to move, the panel detection sensor (340) recognizes the laminate panel (800).

[0092] Here, if the laminate panel (800) is a normal panel, the movement of the pusher bar (330) is maintained.

[0093] At this time, if the glass panel (801) constituting the laminate panel (800) is broken, the laminate panel (800) may bend or twist. If the laminate panel (800) mounted on the upper surface of the panel mounting table (140) is in such a defective state, the panel detection sensor (340) can transmit the information to the server or manager to notify the suspension of the process.

[0095] Meanwhile, the process frame (100) may further include at least one panel fixing cylinder (160) that extends downward along a third direction when a laminate panel (800) that has been transported along a first direction from the inlet side (101) of the process frame (100) is detected on the lower surface of the first connecting body (112) and is formed to be extendable on one side of the first connecting body (112) as shown in FIG. 6.

[0096] Additionally, the process frame (100) may further include a panel fixing bar (162) that is connected to the lower end of a fixing rod (161) that is accessible from a panel fixing cylinder (160) and extends along a second direction.

[0097] In addition, the process frame (100) may further include a panel trimming part (170) provided on one side of the first connecting body (112) that is adjustable in height along the third direction and moves along the second direction to trim the edge of the laminate panel (800).

[0099] Here, the panel trimming section (170) may include a horizontal driving body (171) that receives driving force on the upper surface of the first connecting body (112) as shown in FIGS. 7 and 8 and is capable of reciprocating along a second direction, and a vertical driving body (172) that is mounted on one side of the horizontal driving body (171) and receives driving force and is capable of adjusting its height position along a third direction.

[0100] At this time, the panel trimming unit (170) may include a sanding wheel (173) that is coupled to the vertical driving body (172) and receives driving force to rotate and trim the edge of the laminate panel (800).

[0101] Additionally, the panel trimming section (170) may include a second LM guide (174) that is formed extending along a second direction on the upper surface of the first connecting body (112) and allows the horizontal driving body (171) to reciprocate, and a third LM guide (175) that is formed along a third direction on the horizontal driving body (171) and allows the vertical driving body (172) to reciprocate.

[0102] Additionally, the panel trimming section (170) may include a wheel drive motor (176) that is coupled to the vertical driving body (172), connected to the sanding wheel (173), and has a drive shaft (not shown below) formed along a third direction.

[0103] And, the panel trimming section (170) may include a sealing box (177) that is connected to the third LM guide (175), has an inner surface facing the outer surface of the sanding wheel (173), and prevents dust from scattering when the sanding wheel (173) is operated.

[0104] Additionally, the panel trimming section (170) may include a seal scrubber (178) that extends toward the upper surface of the base (150) on both sides of the sealing box (177) and moves along the second direction to prevent dust and by-products generated by the movement of the horizontal travel body (171) in the second direction and the operation of the sanding wheel (173) from scattering.

[0106] Meanwhile, it can be seen that the hot air injection unit (200) is positioned between the third support frame (130) and the second support frame (120) as shown in FIG. 9.

[0107] Before describing the hot air injection unit (200), we will examine the roll sheet discharge unit (180) for discharging the roll sheet (802) as shown in FIGS. 9 to 11.

[0108] The roll sheet discharge section (180) is formed in the third support frame (130) and is positioned between the third support frame (130) and the second support frame (120).

[0109] The roll sheet discharge unit (180) is reciprocating along the second direction and discharges the roll sheet (802), formed by winding solar cells peeled from the laminate panel (800) by the peeling blade (231) of the hot air injection unit (200) into a roll shape, along the second direction.

[0110] This roll sheet discharge section (180) may include a fourth LM guide (181) formed along a second direction on the upper surface of a third connecting body (132) of a third support frame (130), a discharge moving body (182) that can reciprocate along the fourth LM guide (181), and a discharge support bar (183) mounted on one side of the discharge moving body (182) and extending along a third direction.

[0111] Additionally, the roll sheet discharge section (180) may include a flat discharge piece (184) having upper and lower end edges that extend along a first direction and have a certain width and width, mounted on the lower end of the discharge support bar (183), and a stroke stopper (185) provided at both ends of the fourth LM guide (181) to restrict the movement of the discharge moving body (182).

[0113] Meanwhile, the automated surface peeling device for waste solar modules using high-temperature, high-pressure air according to a preferred embodiment of the present invention may further include a panel discharge unit (190) formed on a second connecting body (122) as shown in FIGS. 12 and 13, which discharges a glass panel (801) from which a roll sheet (802) formed by a solar cell peeled from and wound from a laminate panel (800) has been removed along a first direction.

[0114] Here, the panel discharge unit (190) may include a second roller lifting cylinder (191) installed on the upper surface of the second connecting body (122), and a pair of second panel transfer rollers (192) arranged vertically with both ends rotatably supported along a second direction between the lower surface of the second connecting body (122) and the upper surface of the base (150) and having outer surfaces facing each other.

[0116] Meanwhile, the hot air injection unit (200) may include a first roller lifting cylinder (210) installed on the upper surface of a third connecting body (132) that constitutes a third support frame (130) as shown in FIG. 9 and FIG. 11 to 13, and at least one pair of upper and lower first panel transfer rollers (220) that are vertically arranged and rotate by receiving driving force, with both ends rotatably supported along a second direction between the lower surface of the third connecting body (132) and the upper surface of the base (150) and having outer surfaces facing each other.

[0117] And, the hot air injection unit (200) may include at least one fourth support column (241) protruding from each of the upper edges of the base (150), a fourth connecting body (242) connecting the upper ends of each of the at least one fourth support column (241), and a fourth support frame (240) positioned between the third support frame (130) and the second support frame (120).

[0118] And, the hot air injection unit (200) may include a peeling blade (231) mounted on a fourth support frame (240) for peeling off solar cells from a laminated panel (800) discharged between a pair of first panel transfer rollers (220), and a hot knife section (230) for spraying high-temperature, high-pressure air along a second direction at the entry point of the peeling blade (231) for the solar cells.

[0119] Here, the peeling blade (231) of the hot air injection unit (200) is installed on the upper surface of the base (150), positioned between the second support frame (120) and the third support frame (130), formed at a certain angle of inclination with respect to the upper surface of the base (150), peels off solar cells from the laminate panel (800), and can move up and down along the third direction by receiving driving force.

[0120] At this time, the hot air injection unit (200) may include a plurality of hot air injection nozzles (232) formed along a second direction on the upper surface of the base (150) and positioned between a pair of first panel transfer rollers (220) and a peeling blade (231), and simultaneously injecting high-temperature, high-pressure air along the lower edge of the peeling blade (231).

[0122] Meanwhile, the hot knife unit (230) further includes a blade lifting body (233) that fixes and supports the upper part of the peeling blade (231), and a blade lifting cylinder (234) mounted on one side of the fourth support frame (240) that lifts and reciprocates the blade lifting body along the third direction, and can be seen that the solar cell is peeled from the laminate panel (800) and comes into contact with the blade lifting body (233) while the roll sheet (802) is wound and formed.

[0124] Hereinafter, the overall operation process of an automated surface peeling device for waste solar modules using high-temperature, high-pressure air according to a preferred embodiment of the present invention will be explained sequentially with reference to FIGS. 1 to 13.

[0125] First, the operator inserts a laminate panel (800) with the aluminum frame removed onto the upper surface of a panel mounting table (140) provided at the entrance side (101) of the process frame (100).

[0126] When the automatic process starts, the pusher bar (330) of the panel moving pusher (300) begins to move along the first direction as shown in FIGS. 4 and 5.

[0127] At this time, a plurality of panel detection sensors (340) mounted on the pusher bar (330) detect the state of the laminate panel (800).

[0128] If the laminate panel (800) is detected to be in an abnormal state, such as broken or bent, the control unit stops the process and generates a notification.

[0129] When the laminate panel (800) is detected as normal, the panel moving pusher (300) continues to push the laminate panel (800) in the first direction and transports it to the point where the panel trimming part (170) is located.

[0130] Next, as shown in FIGS. 6 to 8, when the laminate panel (800) reaches the trimming position, the length of the laminate panel (800) is measured based on the travel distance of the panel moving pusher (300).

[0131] Next, the panel fixing cylinder (160) extends downward in the third direction so that the panel fixing bar (162) presses the upper surface of the laminate panel (800) to firmly fix it.

[0132] When the panel fixing is complete, the panel trimming unit (170) starts operating.

[0133] While the wheel drive motor (176) is rotating the sanding wheel (173) at high speed, the vertical travel body (172) descends in a third direction to bring the sanding wheel (173) into contact with the edge of the panel.

[0134] Afterwards, as the horizontal travel body (171) moves along the second direction, the sanding wheel (173) precisely grinds (trims) the edge of the laminate panel (800).

[0135] The dust generated during this process is prevented from scattering by the sealing box (177) and the seal scrubber (178).

[0136] When trimming is completed, the panel fixing cylinder (160) rises to release the fixation of the laminate panel (800), and the panel moving pusher (300) moves again in the first direction to transfer the laminate panel (800) to the next process, the hot air injection unit (200).

[0137] Next, as shown in FIGS. 12 and 13, the trimmed laminated panel (800) enters the first panel transfer roller (220) provided at the front of the hot air injection unit (200).

[0138] The first roller lifting cylinder (210) descends, and the upper and lower pair of first panel transfer rollers (220) grip the laminate panel (800).

[0139] Based on the measured length of the laminate panel (800), the first panel transfer roller (220) is driven to transfer the laminate panel (800) to the exact peeling start point of the hot knife section (230) and then stop.

[0140] Next, a full-scale peeling process is initiated as shown in FIGS. 9, 12, and 13.

[0141] The blade lifting cylinder (234) of the hot knife unit (230) operates to lower the blade lifting body (233), and accordingly, the peeling blade (231) enters the peeling point of the laminate panel (800).

[0142] At the same time, the hot air injection nozzle (232) locally sprays high-temperature, high-pressure air in a second direction toward the entry point of the peeling blade (231), thereby instantaneously melting the adhesive layer (EVA) between the reinforced glass and the solar cell of the laminate panel (800).

[0143] When the adhesive layer melts, the first panel transfer roller (220) and the second panel transfer roller (192) of the panel discharge section (190) start driving simultaneously.

[0144] By the tension of the two rollers (220, 192) pulling the laminate panel (800) in the first direction, the peeling blade (231) easily cuts the molten adhesive layer and separates the solar cell from the reinforced glass.

[0145] The separated solar cell comes into contact with the outer surface of the blade lifting body (233) and is naturally wound into a roll shape to form a roll sheet (802).

[0146] Finally, the discharge process is carried out as shown in FIGS. 3, 9 to 13.

[0147] Immediately after the panel moving pusher (300) transfers the laminated panel (800) to the first panel transfer roller (220), it returns to the inlet side (101) of the process frame (100) to prepare for the input of the next laminated panel (800).

[0148] As the peeling process proceeds, the clean glass panel (801) from which the roll sheet (802) has been removed is discharged to the exit side (102) of the process frame (100) through the second panel transfer roller (192) and finally transferred to the panel conveyor (900).

[0149] When the peeling of the entire laminate panel (800) is completed and the winding of the roll sheet (802) is finished, the roll sheet discharge unit (180) is operated.

[0150] As the discharge moving body (182) of the roll sheet discharge section (180) moves along the second direction from the starting point to the end point, that is, from the stroke stopper (185) at one end of the fourth LM guide (181) to the stroke stopper (185) at the other end of the fourth LM guide (181), the discharge piece (184) pushes the roll sheet (802) to the side of the second direction to discharge it.

[0151] With this, all automated processes are completed.

[0153] As described above, the basic technical concept of the present invention is to provide an automated surface peeling device for waste solar modules utilizing high-temperature, high-pressure air, which maximizes energy efficiency and fundamentally prevents damage to tempered glass by spraying high-temperature, high-pressure air locally only at the point where peeling occurs, without heating the entire panel, during the process of transporting a panel from which the aluminum frame has been removed from the waste solar module.

[0154] And, it goes without saying that many other variations and applications are also possible for those skilled in the art within the scope of the basic technical concept of the present invention. Explanation of the symbols
