[0002] With the global demand for alternative energy sources due to the depletion of fossil fuels such as oil and coal, and for eco-friendly green energy to address environmental pollution caused by their use, the technological development of various types of nature-friendly energy is actively underway. Among these diverse types of nature-friendly energy, the development of technologies utilizing solar energy is particularly active.

[0003] Solar panels, which form the core of solar power generation facilities, have a lifespan of approximately 20 to 30 years, making the disposal of discarded solar panels a significant issue worldwide. However, technologies for efficiently integrating, processing, and recycling facilities that become waste due to factors such as exceeding their service life have not yet been widely researched. Solar panels are modularized within a sturdy aluminum frame to protect them from external impacts or adverse weather conditions and consist of a backsheet, an EVA adhesive layer, solar cells, tempered glass, and solar cell scrap.

[0020] As illustrated in these drawings, a waste solar panel processing device according to one embodiment of the present invention comprises a first peeling section (200) and a second peeling section (400).

[0021] As shown in FIGS. 1 to 4, the first peeling unit (200) is configured to enable the peeling of cell scrap (12) from the solar panel (10) from the reinforced glass in a waste solar panel, and is equipped with a moving block, a cutting blade (240), a first peeling blade (250), a first sensing unit (260), and a first control means (270).

[0022] The above-mentioned moving block includes a guide rod (220), a moving member (230), and a lifting member (231) to be described later, and is configured to be movable in a direction perpendicular to the direction of transport of the heated solar panel (10) during transport by the first transport unit (100), and the cutting blade (240) and the first peeling blade (250) are configured to be movably positioned on the lower side of the transported solar panel (10).

[0023] The above moving block is configured to be able to be raised and lowered by the first adjustment means (270), and by enabling the cutting blade (240) and the first peeling blade (250) to be raised and lowered, the position of the cutting blade (240) and the first peeling blade (250) can be adjusted according to the height of the cell scrap (12) of the solar panel on the transfer line due to the working environment or foreign substances.

[0024] Here, the first transfer unit (100), as shown in FIG. 1, enables the solar panel (10) to be transferred to the first peeling unit (200) and includes a first transfer unit frame (110), a roller (120), and a heating member (130). The first transfer unit frame (110) of the first transfer unit (100) is installed in a workspace and enables the solar panel (10) to move along a transfer line (TL) to the first peeling unit (200).

[0025] The rollers (120) of the first transfer unit (110) are provided in multiple numbers on the frame (110) of the first transfer unit along the transfer line (TL) and are spaced apart from each other to form a gap. The rollers (120) of the first transfer unit (110) consist of a lower roller (122) and an upper roller (124) that face each other vertically and form a space between them to allow the solar panel (10) to pass through. The lower roller (122) and the upper roller (124) of the rollers (120) rotate in opposite directions to enable the transfer of the solar panel (10) along the transfer line (TL).

[0026] The heating member (130) of the first transfer unit (110) is installed on the first transfer unit frame (110) and is provided between each roller (120) to heat the solar panel being transferred along the transfer line, thereby lowering the binding force of the cell scrap (120) to the tempered glass and enabling easy peeling.

[0027] As shown in FIGS. 2 and 4, the cutting blade (240) of the first peeling section (200) is installed on a movable block that is movably installed on the first peeling section frame (210), and moves together with the movable block in a direction perpendicular to the transport line of the solar panel (10), and supports the leading edge of the solar panel (10) upward. During the process of moving in the perpendicular direction, the cutting blade (240) cuts a part of the cell scrap (12) of the solar panel (10).

[0028] The first peeling blade (250) of the first peeling section (200) is installed on the moving block together with the cutting blade (240), and when moving in the orthogonal direction together with the cutting blade (240), it peels off a portion of the cut cell scrap (12) from the tempered glass (14). The tip of the first peeling blade (250) is positioned between the tempered glass (14) and the cell scrap (12) while moving up and down together with the moving block to peel off a portion of the cell scrap (12).

[0029] The first sensing unit (260) of the first peeling unit (200) can be installed on the first peeling unit frame (210) and detects a solar panel (10) approaching the cutting blade (240) while being transported along the transport line (TL), thereby enabling the determination of the location of cell scrap in each solar panel. The first sensing unit (260) transmits a detection signal based on the detection of the solar panel (10) to a control unit (not shown), and the control unit controls the first adjustment means according to the location of the cell scrap based on the detection signal, thereby enabling the position of the first peeling blade (250) and the cutting blade (240).

[0030] The control unit compares the cell scrap height of a solar panel set on the transfer line with the cell scrap height of a detected waste solar panel, and raises the moving block by the height of the cell scrap of the waste solar panel that has increased in height due to foreign substances, etc., thereby raising the first peeling blade, and positioning the first peeling blade between the tempered glass of the waste solar panel and the cell scrap. Here, the height of the cell scrap refers to the thickness of the cell scrap on the transfer line and may be set based on data received through an input means.

[0031] As shown in FIGS. 5 and 6, the first control means (270) of the first peeling unit (200) is installed on the moving block and enables the moving block to be raised and lowered based on a detection signal by the first sensing unit (260), and raises and lowers the first peeling blade (250) and the cutting blade (240) so that the tip of the first peeling blade is positioned between the reinforced glass of the solar panel (10) and the cell scrap. The first control means (270) may include a control unit and may be driven according to a control signal based on a detection signal by the control unit.

[0032] The second peeling unit (400) receives a solar panel from the second transfer unit (300) provided between the first peeling unit (200) and the second peeling unit (400), and enables the remaining cell scrap (12) from the solar panel to be peeled off from the tempered glass. Here, the second transfer unit (300) includes a second transfer unit frame (310) and a roller (320). The second transfer unit frame (310) is provided between the first peeling unit (200) and the second peeling unit (400), and enables the installation of the roller (320) so that the solar panel from which a portion of the cell scrap (12) has been peeled off can be continuously transported along the transfer line.

[0033] As shown in FIG. 1, the rollers (320) of the second transfer unit (300) are provided in multiple numbers along the transfer line (TL) and are spaced apart from each other, and include a lower roller (322) and an upper roller (324), forming a space between the lower roller and the upper roller for moving the solar panel (10).

[0034] As shown in FIGS. 7 and 8, the second peeling unit (400) comprises a second peeling blade (430), a second sensing unit (460), and a second control means (450) to peel off the remaining cell scrap from the solar panel (10) that continues to move after passing between the lower roller and the upper roller of the second conveying unit. The second peeling blade (430) of the second peeling unit (400) is installed on the second peeling unit frame (410) and is installed facing the conveying direction of the solar panel (10), and its tip is positioned between the partially peeled cell scrap (12) and the tempered glass (14), thereby causing the remaining cell scrap (12) to be peeled off from the tempered glass during the movement of the solar panel.

[0035] The second peeling section (400) may be equipped with a roller (420) to continuously transport the solar panel (10) toward the second peeling blade (430). The roller (420) includes a lower roller (422) and an upper roller (424), and forms a space between the lower roller and the upper roller for the movement of the solar panel (10).

[0036] The second sensing unit (460) of the second peeling unit (400) is installed on the frame (410) of the second peeling unit and detects the approaching solar panel so as to determine the location of the cell scrap (12) in each solar panel approaching the second peeling blade (430). The second control means (450) of the second peeling unit (400) raises and lowers the second peeling blade (430) based on the detection signal from the second sensing unit, and positions the tip of the second peeling blade (430) between the tempered glass and the cell scrap (12).

[0037] The second control means (450) of the second peeling unit (400) described above may include a control unit, similar to the first control means of the first peeling unit (200) described above, and may be driven according to a control signal of the control unit based on a detection signal. The determination of the height of the cell scrap (12) by the second peeling unit (400) may be performed in the same manner as the determination method by the control unit of the first peeling unit (200).

[0038] A waste solar panel processing device according to one embodiment of the present invention having such a configuration has the effect of enabling precise separation of solar cell scraps of solar panels having different heights (thicknesses) from the tempered glass on the transfer line due to the working environment and foreign substances in the solar cell part, and enabling a reduction in working time for the separation process.

[0039] Meanwhile, the second peeling section (400) may further include a curling prevention member (440) as shown in FIG. 7. The curling prevention member (440) is positioned between the second peeling blade (430) and the roller (420), with one side positioned on the lower roller (422) side of the roller (420) and the other side extended downwards toward the lower roller (422) in a bent state, thereby preventing the remaining cell scrap (12) peeled by the second peeling blade (430) from being curled toward the lower roller (422) during the movement of the solar panel and allowing it to move toward the lower side of the lower roller.

[0040] As previously described, the moving block of the first peeling section (200) employed in this embodiment is preferably formed to include a guide rod (220), a moving member (230), and a lifting member (231) so that it can move back and forth in a direction perpendicular to the direction of movement of the solar panel (100) and can be raised and lowered by the first adjustment means (270).

[0041] As shown in FIGS. 3 and 4, the guide rod (220) of the above-mentioned moving block can be installed on the first peeling part frame (210) of the first peeling part and guides the moving member (230) so that the moving member (230) can reciprocate in a direction perpendicular to the direction of movement of the solar panel. The moving member (230) of the above-mentioned moving block is provided with a through hole on the central side so that the guide rod (230) is positioned to pass through it, and receives power from a motor, etc., driven according to a control signal, and moves along the guide rod (230) to enable the movement of the lifting member (231), the first peeling blade (250), the cutting blade (240), and the first adjustment means (270).

[0042] Additionally, a sensor (not shown) capable of measuring the pressure applied to the cutting blade (240) and the first peeling blade (250) may be installed in the moving member (230). The cutting blade (240) and the first peeling blade (250) configured in this way may be driven to have a set pressure value by being raised or lowered by a lifting member from the moving member (230) according to the pressure measured when they come into contact with the solar panel (10) to peel off the cell scrap (12).

[0043] The lifting member (231) of the above-mentioned moving block is installed to be vertically movable on the moving member (230) by the first control means (270), and allows the cutting blade (240) and the first peeling blade (250) to be installed toward the lower part of the solar panel (10). The lifting member (231) is raised by the first control means, which is driven by a control signal based on a detection signal by the first sensing unit (260), and raises the cutting blade (240) and the first peeling blade (250), thereby enabling the peeling of a portion of cell scrap from solar panels of various thicknesses.

[0044] As shown in FIGS. 5 and 6, the first control means (270) of the first peeling part (200) is installed between the moving member (230) and the lifting member (231) of the moving block to enable the lifting of the lifting member (231), and includes a guide rod (271) and a cylinder (272).

[0045] The guide rod (271) is formed as a pair, with one end connected to the moving member (230) and the other end extending toward the lifting member (231) and being inserted into and withdrawn from a pair of rod grooves (271a) formed in the lifting member (231), thereby guiding the lifting of the lifting member.

[0046] The cylinder (272) of the first control means (270) receives power from hydraulic or pneumatic pressure to raise and lower the lifting member (231), and is composed of a cylinder rod (272a) and a cylinder body (272b). One end of the cylinder rod (272a) of the cylinder is connected to the moving member (230), and the other end is formed to extend from one end along the longitudinal direction of the guide rod.

[0047] The cylinder body (272b) of the above cylinder (272) is provided on the lifting member (231) and accommodates the other end of the cylinder rod (272a), and by receiving power, the other end of the cylinder rod is extended or retracted to enable lifting of the moving member of the lifting member. The driving of the cylinder can be driven based on a detection signal from the first sensing unit (260) as described above. It is preferable that the cylinder (272) be positioned between a pair of guide rods (271) for stable lifting of the lifting member (231).

[0048] Meanwhile, the cutting blade (240) of the first peeling section (200) is configured to perform the role of cutting the cell scrap (12) portion and simultaneously supporting the solar panel (10) upward, as shown in FIGS. 4 and 6, and may be formed in an overall circular shape and provided in a needle shape so as to perform the function of a blade along the perimeter. When viewed from the front, the cutting blade (240) has a curved connecting line between the top end (T1) and the top end (F1), so that even if the top end comes into contact with the curved solar panel (10), the lower part of the elongated solar panel (10) follows the curved line of the cutting blade (240) up to the top end (T1), and the cutting operation through the cutting blade (240) can begin while the lower part of the solar panel (10) is positioned at the top end (T1) of the cutting blade (240).

[0049] The second control means (450) of the second peeling unit (400) employed in this embodiment may comprise a lifting rod (451) and a lifting drive unit (452), as shown in FIGS. 7 and 8. One end of the lifting rod (451) of the second control means (450) is connected to the second peeling blade (430), and the other end is formed to extend from that one end toward the bottom side. In addition, the lifting drive unit (452) of the second control means (450) accommodates the other end of the lifting rod (451) and receives power according to a control signal based on the detection signal to lift the lifting rod (451), thereby enabling the second peeling blade (430) to be lifted and allowing for precise peeling of cell scraps of various heights. The above lifting drive unit (452) can be driven by receiving power from a motor, and the lifting rod can be raised by hydraulic or pneumatic pressure.

[0050] The lifting rod (451) of the second adjustment means (450) may be formed in the form of a screw, and the lifting drive unit (452) may be screw-coupled with the lifting rod and may be able to lift by receiving power and rotating the lifting rod. The first adjustment means and the second adjustment means may be formed in the form of a ball screw.
