Description

Technical Field

[0001] The present invention relates to an automatic separation device for tempered glass of a solar cell module, and particularly to an automatic separation device for tempered glass of a solar cell module that can separate the tempered glass from a solar cell in a plate shape from a single-sided or double-sided solar cell module whose service life has ended, thereby improving the recycling value.

Background Art

[0002] A solar cell module is the core of a solar power generation facility. The lifespan of such a solar cell module is approximately 20 to 30 years, and currently, the disposal of solar cell modules discarded worldwide has become an important issue.

[0003] However, technologies for efficiently integrating and recycling facilities discarded due to the expiration of the service life of solar power generation facilities have not yet been widely studied. Here, a solar cell panel is modularized into a sturdy aluminum frame to be protected from external impacts and bad weather. Such a solar cell panel includes a backsheet, an EVA adhesive layer, a solar cell, an EVA adhesive layer, and tempered glass.

[0004] Examples of inventions for recycling such solar cell panels include Patent Document 1: Japanese Patent No. 5938309, "Recycling Method of Solar Cell Panel" (hereinafter referred to as "prior art").

[0005] The prior art discloses a device including a metal grinding wheel for crushing a solar cell, a recovery hood for recovering crushed materials, and a sensor for measuring the content of metal components in order to separate and recover useful metals and harmful metals contained in the glass substrate of the solar cell panel. The prior art classifies the crushed materials of the solar cell based on information regarding the metal components received by the electronic valve from the sensor.

[0006] However, the components that can be recycled in a solar panel are generally an aluminum frame, tempered glass, the materials inside the solar cell, and the copper conductors connected to the solar cell. Therefore, similar to the prior art, the process of shredding and separating the entire solar panel results in poor efficiency in the recovery of the solar cell or tempered glass.

[0033] As shown in FIGS. 1 and 2, in the present invention, the first unit 100 formed on the base 400 aligns the left and right, front and rear of the solar cell module 500, the second unit 200 conveys the solar cell module 500 aligned along the upper surface of the base 400, and the third unit 300 separates and removes the second tempered glass 520 and the solar cell 530 from the first tempered glass 510 of the solar cell module 500, and the application of the embodiment of the structure becomes possible.

[0034] First, the base 400 is provided to provide a space and area where the first, second, and third units 100, 200, and 300 to be operated are installed and the solar cell module 500 is conveyed along the first direction.

[0035] The first unit 100 may include a first side alignment means 101 and a second side alignment means 102 formed on one side of the upper surface of the base 400.

[0036] The first side alignment means 101 is provided to move the solar cell module 500 carried in along the first direction from one side of the upper surface of the base 400 to the other side of the upper surface in the second direction orthogonal to the first direction and align the edges on both sides of the solar cell module 500 on the upper surface of the base 400.

[0037] The second side alignment means 102 is provided to move in the first direction from the other side of the upper surface of the base 400 to one side of the upper surface and align the edges connecting the ends of both side edges of the solar cell module 500 on the upper surface of the base 400.

[0038] The second unit 200 includes a transfer panel 201 that is seated so that the surface of the solar cell module 500 faces the upper surface of the base 400 and reciprocates along the first direction from one end side to the other end side of the upper surface of the base 400.

[0039] Here, the first tempered glass 510 (see FIG. 1(b) below) is disposed on one surface of the solar cell 530 (see FIG. 1(b) below) to form the surface of the solar cell module 500, and the second tempered glass 520 (see FIG. 1(b) below) is disposed on the other surface of the solar cell 530 to form the back surface of the solar cell module 500. The third unit 300 may include a vertical roller 301 and a hot knife 302 disposed between one end and the other end of the upper surface of the base 400.

[0040] The vertical roller 301 is provided to allow the transfer in the first direction while pressing down the second tempered glass 520 of the solar cell module 500 being transferred by the transfer panel 201.

[0041] The hot knife 302 is provided to separate the second tempered glass 520 and the solar cell 530 from the first tempered glass 510 in a heated state. Of course, the present invention can be applied to the above-described embodiments, and can also be applied to various other embodiments.

[0042] First, the base 400 may further include a plurality of horizontal bars 401 arranged in parallel along the first direction on the upper side of the base 400 as shown in the figure, and a plurality of vertical bars 402 arranged in parallel along the second direction on the upper side of the base 400 and intersecting the plurality of horizontal bars 401.

[0043] The base 400 can further include a plurality of vertical bars 403 that are arranged in parallel along a third direction orthogonal to the first and second directions along the edges on both the left and right sides of the base 400, and are connected to the edges on both the left and right sides of an upper frame 410 that is formed by a plurality of horizontal bars 401 and a plurality of vertical bars 402 and is arranged to face the upper surface of the base 400. Therefore, it can be understood that a part of the first unit 100, the second unit 200, and the third unit 300 described later are mounted on the upper frame 410.

[0044] On the other hand, the first side alignment means 101 can include a first rail bar 110 that is fixed to an upper frame 410 arranged on the upper part of the upper surface of the base 400 as shown in FIG. 3, is provided in the second direction, and is arranged in a row on both the left and right sides of the upper part of the upper surface of the base 400.

[0045] The first side alignment means 101 can include a first moving body 120 that is respectively mounted on the tip ends of the first rail bar 110 arranged on the left side of the upper part of the upper surface of the base 400 and the tip ends of the first rail bar 110 arranged on the right side of the upper part of the upper surface of the base 400, and can reciprocate in the second direction along the first rail bar 110 and approach or separate from each other.

[0046] The first side alignment means 101 can include a first actuator 122 that is respectively mounted on the end parts of the first rail bar 110 arranged on the left side of the upper part of the upper surface of the base 400 and the end parts of the first rail bar 110 arranged on the right side of the upper part of the upper surface of the base 400, and transmits the driving force required for each reciprocation of the first moving body 120.

[0047] The first side alignment means 101 can further include a first reciprocating body 130 that is connected to each of the first moving bodies 120, interlocks with the first moving bodies 120, and can reciprocate in the second direction and approach or separate from each other.

[0048] Note that the first side alignment means 101 can include a first alignment bar 141 provided on the lower side of each of the first reciprocating bodies 130, arranged along the first direction, and having a lower surface facing the upper surface of the base 400.

[0049] Therefore, the lower part of the first reciprocating body 130 and the first alignment bar 141 will form a first stopper 140 for aligning the left and right edges of the solar cell module 500 placed on the upper surface of the base 400.

[0050] Here, the first reciprocating body 130 can include a first upper bar 131 coupled to the upper surface of each of the first reciprocating bodies 130 and extending in the first direction, a first side bar 132 coupled to both ends of the first upper bar 131 so as to be orthogonal to each other and extending in the second direction, and a first support bar 133 coupled to the ends of each of the first side bars 132 so as to be orthogonal to each other and extending in a third direction orthogonal to the first and second directions.

[0051] At this time, it can be understood that the lower end portions of each of the first support bars 133 are coupled to the upper surface of the first alignment bar 141, and the first stopper 140 is formed by a pair of first support bars 133 and the first alignment bar 141.

[0052] On the other hand, the second side alignment means 102 can include a second rail bar 150 fixed to an upper frame 410 disposed on the upper part of the upper surface of the base 400 as shown in FIG. 3, provided in the first direction, and disposed at the center of the upper part of the upper surface of the base 400.

[0053] And the second side alignment means 102 can include a second moving body 160 mounted on the tip of the second rail bar 150 and reciprocating in the first direction along the second rail bar 150.

[0054] And the second side alignment means 102 can include a second actuator 162 mounted on the end of the second rail bar 150 for transmitting the driving force required for the reciprocation of the second moving body 160.

[0055] And the second side alignment means 102 can include a second reciprocating body 170 that is connected to the second moving body 160, interlocks with the second moving body 160, and reciprocates in the first direction.

[0056] Further, the second side alignment means 102 can include a second alignment bar 181 that is provided on the lower side of each of the second reciprocating bodies 170, is arranged along the second direction, and is orthogonal to the upper surface of the base 400.

[0057] In addition, the second side alignment means 102 can include support pieces 190 that are respectively formed on both sides of one surface of the second alignment bar 181 and support the solar cell module 500.

[0058] Therefore, it can be understood that the second alignment bar 181 and the pair of support pieces 190 form a second stopper 180 that aligns the edges of the other end of the solar cell module 500 placed on the upper surface of the base 400.

[0059] Here, the second reciprocating body 170 can include a second upper bar 171 that is coupled to the upper surface of the second moving body 160 and extends in the second direction, and second support bars 172 that are respectively coupled to both ends of the second upper bar 171 so as to be orthogonal and extend to the upper surface side of the base 400. At this time, it can also be understood that the lower end portions of each of the second support bars 172 are respectively coupled to both sides of the other surface of the second alignment bar 181. In addition, the pair of support pieces 190 can be adjusted in height along a third direction that is orthogonal to the first direction and the second direction with respect to both sides of one surface of the second alignment bar 181.

[0060] For this purpose, as shown in FIG. 4, the support piece 190 includes an adjustment piece 191 arranged so as to be height-adjustable along the third direction on both sides of one surface of the second alignment bar 181, at least one or more adjustment slots 192 formed in a long hole shape along the third direction in the adjustment piece 191, and a bending piece 193 extending from the lower end portion of the adjustment piece 191 and orthogonal to one surface of the second alignment bar 181.

[0061] Here, the width size of the adjustment slot 192 in the second direction is larger than or the same as the outer diameter of the main body of a fastener (not shown below) including a bolt for fixing the adjustment piece 191 to the second alignment bar 181.

[0062] Therefore, the head formed at the tip of the main body of the fastener is jammed and fixed outside the adjustment slot 192 so that the adjustment piece 191 can be fixed to be height-adjustable with respect to the second alignment bar 181.

[0063] On the other hand, as shown in FIGS. 3 and 5, the second unit 200 can further include a third rail bar 210 formed in the first direction from the edge of one end of the upper surface of the base 400 to the edge of the other end, and a third moving body 220 that can reciprocate along the third rail bar 210 and supports the transfer panel 201.

[0064] And the second unit 200 can further include a third actuator 230 that is mounted on one side of the left or right edge of the left and right sides of the transfer panel 201 and generates a driving force for the third moving body 220 to reciprocate along the third rail bar 210.

[0065] And the second unit 200 can further include a mounting and fixing means 202 that is formed on the transfer panel 201 and supports the photovoltaic module according to the dimensions and size of the solar cell module 500 carried in, and maintains the state in which the photovoltaic module is fixed to the transfer panel 201.

[0066] The second unit 200 can further include a terminal piece 231 mounted on one side of the right or left edge of the transfer panel 201 and electrically connected to the third actuator 230 and the mounting and fixing means 202.

[0067] In addition, the second unit 200 can further include a cable (not shown below) that electrically connects the terminal piece 231 and an external power source to supply power necessary for the operation of the third actuator 230 and the mounting and fixing means 202. And the second unit 200 can further include a foldable guide 232 for the cable that houses the cable from one edge of the terminal piece 231, allows rotational folding, and extends from one end side to the other end side of the upper surface of the base 400 in parallel with the third rail bar 210.

[0068] Also, the second unit 200 can further include a bar-shaped inlet stopper 203 that protrudes along the second direction inside the edge of one end of the transfer panel 201, and on which the edge of one end of the solar cell module 500 placed, aligned, and carried onto the upper surface of the transfer panel 201 is hung and fixed.

[0069] On the other hand, the mounting and fixing means 202 can include through holes 242 formed in a plurality of rows and columns on the upper surface of the transfer panel 201, and mounting pins 240 formed in a columnar shape that have an outer diameter smaller than the inner diameter of the through holes 242 and can enter and exit from the upper surface of the transfer panel 201 through each of the through holes 242 and have an upper end surface that contacts the surface of the solar cell module 500.

[0070] And the mounting and fixing means 202 can further include a pin actuator (not shown below) that is connected to the lower end of each of the plurality of mounting pins 240 and generates a driving force to raise and lower some or all of the plurality of mounting pins 240, and a negative pressure generation source (not shown below) formed on one side of the base 400.

[0071] The placement and fixing means 202 may further include a vacuum suction portion (not shown hereinafter) that is formed on the lower surface of the transfer panel 201, connects each of the plurality of through holes 242 to a negative pressure generation source, and generates negative pressure from the upper surface to the lower surface of the transfer panel 201 through the space between the inner peripheral surface of the through hole 242 and the outer peripheral surface of the placement pin 240, thereby bringing the photovoltaic module into contact with and fixing it to the upper surface of the transfer panel 201.

[0072] Moreover, the photovoltaic module supported by the placement pins 240 protruding from the through holes 242 arranged on the outermost periphery among the plurality of through holes 242 formed in rows and columns has a first size that is the largest that can be placed on the transfer panel 201.

[0073] Note that the photovoltaic module supported by the placement pins 240 protruding from the remaining through holes 242 excluding the through holes 242 arranged on the outermost periphery has a second size smaller than the first size, or the size of the photovoltaic module supported by the placement pins 240 gradually becomes smaller by excluding some rows or columns among the plurality of through holes 242 formed in rows and columns.

[0074] It goes without saying that the above-mentioned first size can be the maximum size 501 as shown in FIG. 1(b), and it is possible to separate the tempered glass of photovoltaic modules of various sizes from the photovoltaic module 500 of the maximum size 501 to the photovoltaic module of the minimum size 502.

[0075] On the other hand, when the third unit 300 is specifically observed with reference to FIGS. 1, 2, 6, and 7, it is installed on the upper frame 410 arranged on the upper side of the upper surface of the base 400 and is arranged so that the position can be changed in the third direction, and further includes a preheating block 310 that preheats the photovoltaic module 500 that is seated on and transferred by the vertical roller 301 and the transfer panel 201.

[0076] The third unit 300 can further include a roller support bracket 320 that rotatably supports both ends of each of the vertical rollers 301 arranged along the second direction on both side surfaces before and after the preheating block 310.

Therefore, it can be understood that the lower end of each of the second elevating rods 322 is connected to the upper surface of the roller support bracket 320.

[0082] On the other hand, the third unit 300 is installed on the upper frame 410, can be repositioned along the third direction, is disposed between the preheating block 310 and the hot knife 302, and includes a glass separator 350 that separates and removes the solar cell 530 and the second tempered glass 520 from the first tempered glass 510 when the transfer panel 201 moves from one side to the other side of the upper surface of the base 400.

[0083] Further, the third unit 300 may further include a glass separation guide 360 that is mounted at a plurality of intervals along the upper edge of the heating block 330 and guides the edges of the solar cell 530 and the second tempered glass 520 separated from the first tempered glass 510 to be transferred to the side of the glass separator 350.

[0088] And the third unit 300 can further include a lifting panel 380 to which a heating block 330 is attached and coupled to a plurality of fourth moving bodies 371, and a lifting actuator 372 that is connected to the plurality of fourth moving bodies 371, attached to the lifting support panel 370, and generates a driving force for the reciprocating up and down of the plurality of fourth moving bodies 371.

[0089] The aforementioned glass separation guide 360 can include an anti-lifting bent piece 361 that is fixed to the upper side of the lifting panel 380 or the heating block 330 and includes a vertical plane 361a orthogonal to the upper surface of the base 400, and a horizontal plane 361b that is bent and extended from the edge of the upper end of the vertical plane 361a and is parallel to the upper surface of the base 400.

[0090] And the glass separation guide 360 can include a triangular connecting piece 362 that connects the edges on both sides of each of the vertical plane 361a and the horizontal plane 361b to each other and is orthogonal to both the vertical plane 361a and the horizontal plane 361b.

[0092] Hereinafter, the process of separating the tempered glass by the automatic separation device for the tempered glass of the solar cell module according to the preferred embodiment of the present invention will be examined as follows with reference to FIGS. 1 to 7 and FIG. 8. For reference, the drawing reference numerals not shown in FIG. 8 refer to FIGS. 1 to 7.

[0093] First, in a standby state where the solar cell module 500 is not loaded, the mounting pins 240 protrude from the upper surface of the transfer panel 201, and the transfer panel 201 is placed on one side of the upper surface of the base 400 as shown in Fig. 8(a).

[0094] Thereafter, from the state where the solar cell module 500 is inserted and supported by the plurality of mounting pins 240, the first stopper 140 sequentially aligns the left and right of the solar cell module 500, and the second stopper 180 sequentially aligns the front and rear of the solar cell module 500.

[0095] Next, the mounting pins 240 are lowered, and the front edge and the rear edge of the lowered solar cell module 500 are respectively seated between the inlet stopper 203 and the second stopper 180, and vacuum suction is started through the through holes 242.

[0096] Subsequently, when the third actuator 230 operates and the transfer panel 201 is transferred to the third unit 300 side, the preheating block 310 and the vertical roller 301 come into contact with the second tempered glass 520 of the solar cell module 500.

[0097] Then, while the operation of the third actuator 230 continues, the solar cell module 500 is adsorbed, and the transfer panel 201 on which it is seated is transferred from one side to the other side of the upper surface of the base 400, and the hot knife 302 separates and removes the solar seal 530 and the second tempered glass 520 from the first tempered glass 510.

[0098] Thereafter, while the solar seal 530 and the second tempered glass 520 are ruptured, they are guided along the glass separation guide 360 to the glass separator 350 side, and the glass separator 350 collects the fragments of the solar seal 530 and the second tempered glass 520.

[0099] Next, after the third actuator 230 conveys the transfer panel 201 to the other side of the upper surface of the base 400 as shown in FIG. 8(b), it stops operating, stops the vacuum adsorption of the first tempered glass 510 to the transfer panel 201, and when the placement pins 240 rise, the operator or the robot only needs to collect the first tempered glass 510.

[0100] Finally, after the placement pins 240 descend again, the third actuator 230 operates again to return the transfer panel 201 to one side of the upper surface of the base 400, thereby restarting the operation of separating the tempered glass of the new solar power generation module.

[0101] As described above, it can be understood that the basic technical idea of the present invention is to provide an automatic separation device for the tempered glass of a solar cell module that can separate the tempered glass from the solar cell of a single-sided or double-sided solar cell module whose service life has ended into a plate shape to improve the recycling value. And of course, within the scope of the basic technical idea of the present invention, many other modifications and applications are possible for those with ordinary knowledge in the industry.
