Technical Field

[0001] The present invention belongs to the field of photovoltaic recycling, and in particular relates to a disassembly system and method for recycling photovoltaic components. Background Art

[0002] The structure of a single-glass photovoltaic module includes a backplane, glass, cells and a frame. The cells are bonded between the backplane and the glass, and the frame is set around the backplane and the glass. The service life of a photovoltaic module is about 25 to 30 years. After the service life, the power of the module will decay. With the arrival of the large-scale scrapping period of photovoltaic modules, the recycling of photovoltaic modules has become increasingly important.

[0108] In some embodiments, the second back plate edge stopper drive assembly is entirely replaced by a robot with lifting and lateral movement functions.

[0109] like Figure 8 As shown, the back panel edge support mechanism is located at the rear end of the back panel edge transmission mechanism 200, and is used to support the portion of the photovoltaic component that extends beyond the back panel edge transmission mechanism 200. It includes a back panel edge support seat 211 and a back panel edge support driving assembly 212 for driving the back panel edge support seat 211 to rise and fall.

[0110] The back plate edge support driving assembly 212 includes two cylinders on the left and right. In addition, the back plate edge support driving assembly 212 can also be an electric cylinder or a hydraulic cylinder.

[0111] Working process of back plate edge raising device 2:

[0112] 1. After the frame is removed, the photovoltaic module (which can be placed on a tray) enters the back panel edge raising device 2 and is transported backward by the back panel edge raising transmission mechanism 200;

[0113] 2. When the photovoltaic module reaches the initial heating position, the second back plate edge stopper 208 blocks the photovoltaic module, and then the back plate edge transmission mechanism 200 stops working;

[0114] 3. The second back plate edge stopper 208 is driven by the second back plate edge stopper driving assembly to rise and move forward, no longer blocking the photovoltaic module, and will not block the top of the end of the photovoltaic module. Then the back plate edge pressing driving assembly 202 drives the back plate edge pressing actuator 201 and the hot pressing block 203 to press down the end of the photovoltaic module back plate, heating the glue between the end of the back plate and the glass to melt it.

[0115] 4. After the initial heating is completed, the pressing actuator 201 and the hot pressing block 203 are reset, and the back plate edge transmission mechanism 200 drives the photovoltaic module to continue to move backward. When it reaches the secondary heating position after moving a short distance, the first back plate edge stopper 206 blocks the photovoltaic module, and then the back plate edge transmission mechanism 200 stops working again;

[0116] 5. The back panel edge pressing driving component 202 drives the back panel edge pressing actuator 201 and the hot pressing block 203 to press down the back panel of the photovoltaic module. The hot pressing block 203 heats the glue between the back panel and the glass. The pressing position this time is closer to the front than the initial heating. This is because the hot pressing block 203 cannot press the end of the back panel when the end of the back panel is opened, and can only press the position of the end of the back panel closer to the front. While the pressing actuator 201 and the hot pressing block 203 are pressed down, the back panel edge supporting driving component 212 drives the back panel edge supporting seat 211 to move up and support the end of the photovoltaic module. The position of the back panel edge supporting seat 211 corresponds to the hot pressing block 203, and the support range is larger than the pressing range of the hot pressing block 203. Since the end of the photovoltaic module has left the back panel edge transmission mechanism 200 at this time, it is necessary to support the end of the photovoltaic module, otherwise the pressing down of the back panel edge pressing mechanism lacks support.

[0117] 6. The first backplane edge stopper 206 moves downward and no longer blocks the photovoltaic module. The backplane opening drive assembly 205 drives the backplane opening knife 204 to move horizontally to cut the connection between the backplane and the glass, so that the end of the backplane is separated from the glass, which is convenient for subsequent backplane peeling work;

[0118] 7. After the cutting is completed, the pressing actuator 201 and the hot pressing block 203 move upward, the back panel edge support seat 211 moves downward, and the back panel edge transmission mechanism 200 drives the photovoltaic module to continue to move backward to enter the next process.

[0119] Continue reading Fig.13 The first heating device 1 comprises a first heating transmission mechanism 100 and a first high-temperature tunnel furnace 101. The first heating transmission mechanism 100 is used to transmit photovoltaic modules. The first high-temperature tunnel furnace 101 is a tunnel furnace used to heat photovoltaic modules at high temperatures.

[0120] The first heating and transmission mechanism 100 uses a conveyor belt to support and drive the photovoltaic module forward. In addition, the first heating and transmission mechanism 100 can also use a roller conveyor or other mechanism.

[0121] There are two embodiments of the backplane peeling device 3 of the present invention. In the first embodiment, the structure of the backplane peeling device 3 is as follows:

[0122] See also Figure 10-12The backplane stripping device 3 includes a backplane stripping workbench 306, a backplane stripping mounting frame 307, a backplane stripping transmission mechanism 300, a backplane grabbing mechanism and a backplane stripping mechanism. The backplane stripping transmission mechanism 300 and the backplane stripping mounting frame 307 are both installed on the backplane stripping workbench 306, the backplane stripping mounting frame 307 is located above the backplane stripping transmission mechanism 300, and the backplane grabbing mechanism and the backplane stripping mechanism are both installed on the backplane stripping mounting frame 307. The backplane stripping transmission mechanism 300 is used to transport the photovoltaic module. The backplane stripping workbench 306 is equipped with corresponding sensors. When the photovoltaic module reaches the predetermined position, the sensor is triggered, and the backplane stripping transmission mechanism 300 stops working. The backplane grabbing mechanism is used to grab the end of the backplane of the photovoltaic module and peel the end of the backplane off the glass. The backplane stripping mechanism is used to peel the backplane so that the backplane is completely separated from the glass.

[0123] It can be understood that in the above technical scheme, the stripping device of this embodiment is provided with a backplane stripping transmission mechanism 300, a backplane grabbing mechanism, a backplane stripping mechanism and other structures, which can realize the transmission of photovoltaic modules and the grabbing and stripping of the backplane. The structural design is ingenious and can quickly and efficiently strip the backplane in actual applications, which is very practical.

[0124] Continue reading Fig.10 In this embodiment, the back sheet peeling transmission mechanism 300 adopts a conveyor belt, which is used to support and drive the photovoltaic module forward. In addition, the back sheet peeling transmission mechanism 300 can also adopt a roller conveyor or other mechanisms.

[0125] Further reading Fig.10 The back panel grabbing mechanism in this embodiment includes a back panel clamp 301 and a back panel grabbing drive assembly 302. The back panel clamp 301 is used to grab the end of the back panel, and specifically adopts a pneumatic clamp. In addition, an electric clamp, a hydraulic clamp, etc. can also be adopted. The back panel grabbing drive assembly 302 is used to drive the back panel clamp 301 to move, so that the back panel clamp 301 can drive the end of the back panel to peel off the glass. It specifically adopts a cylinder, which is installed on the upper end of the back panel peeling mounting frame 307, and can drive the back panel clamp 301 to rise and fall. In addition, the back panel grabbing drive assembly 302 can also adopt an electric cylinder, a hydraulic cylinder and other mechanisms.

[0126] Among them, the backplane grabbing drive assembly 302 in this embodiment includes multiple cylinders, and there are also multiple backplane clamps 301. The output shafts of the multiple cylinders are commonly connected to the mounting plate, and the backplane clamps 301 are all installed at the lower end of the mounting plate.

[0127] In order to ensure smooth lifting and lowering of the back plate clamping claw 301, the mounting plate is also slidably matched with the back plate stripping mounting frame 307 through a sliding rod.

[0128] In another embodiment, the backplane grabbing drive assembly 302 can adopt a conventional lifting and lateral movement mechanism such as a robot, so that the backplane grabbing drive assembly 302 not only has the lifting function, but also has the function of moving forward, backward, left and right, etc.

[0129] Continue reading Fig.10 and Fig.11 The back panel peeling mechanism includes a first peeling roller assembly 303 and a second peeling roller assembly 304. The first peeling roller assembly 303 is an active roller, which has a first peeling roller body, a driving motor, a transmission box and other structures and can actively rotate. The second peeling roller assembly 304 is a driven roller. The first peeling roller assembly 303 and the second peeling roller assembly 304 jointly clamp the part of the back panel to peel off the glass. When the first peeling roller assembly 303 rotates, it can drive the second peeling roller assembly 304 to rotate together through the back panel, thereby driving the back panel to be completely peeled off from the glass.

[0130] Among them, in order to avoid the back panel peeling mechanism interfering with the action of the back panel clamp 301 grasping the back panel, the present embodiment is configured as follows: the second peeling roller assembly 304 can move relative to the first peeling roller assembly 303, so that the second peeling roller assembly 304 can approach or move away from the first peeling roller assembly 303, and when the second peeling roller assembly 304 moves away from the first peeling roller assembly 303, the back panel clamp 301 can grasp the back panel.

[0131] Further reading Fig.12 The back panel peeling mechanism further includes a back panel peeling driving assembly 305 , which is used to drive the second peeling roller assembly 304 to move so that the second peeling roller assembly 304 can approach or move away from the first peeling roller assembly 303 .

[0132] Specifically, the second stripping roller assembly 304 includes a second stripping roller main shaft 3040, a plurality of second stripping roller sleeves 3041 fixedly mounted on the second stripping roller main shaft 3040, a second stripping roller connecting sleeve 3042 rotatably mounted on the middle part of the second stripping roller main shaft 3040 through a bearing, a second stripping roller mounting seat 3043 rotatably connected to both ends of the second stripping roller main shaft 3040 through a bearing, a second stripping roller slide 3044 arranged on the second stripping roller mounting seat 3043, and a second stripping roller slide rail 3045 arranged on the back plate stripping mounting frame 307. The second stripping roller slide 3044 and the second stripping roller slide rail 3045 slide together back and forth, and the second stripping roller slide rail 3045 also supports the second stripping roller slide 3044. The back plate stripping drive assembly 305 adopts a cylinder, and its output shaft is connected to the second stripping roller connecting sleeve 3042. In addition, the back plate stripping drive assembly 305 can also adopt an electric cylinder, a hydraulic cylinder, or a slide mechanism.

[0133] In order to prevent the glass from warping up with the back panel during the back panel peeling process, the present embodiment also has the following arrangements: a limiting mechanism 308 is arranged on the back panel peeling workbench 306, and the limiting mechanism 308 is located at the upper end of the back panel peeling transmission mechanism 300, and includes two front and rear limiting rods. When the photovoltaic module moves, the limiting rod is located above the photovoltaic module, which can prevent the photovoltaic module from warping up.

[0134] The working process of the backplane peeling device 3 of this embodiment is as follows:

[0135] The photovoltaic module (which can be placed on a tray) enters the back panel stripping device 3 after being processed by the back panel stripping device 2 and heated by the first heating device 1, and is transported backward by the back panel stripping transmission mechanism 300. When the sensor senses that the photovoltaic module is approaching, the back panel stripping transmission mechanism 300 stops working. At this time, the end of the back panel is just below the back panel clamp 301, and the second stripping roller assembly 304 is away from the first stripping roller assembly 303. The back panel grabbing driving assembly 302 drives the back panel clamp 301 to move downward, and the back panel clamp 301 grabs the back panel. The back panel is moved to the end of the panel, and then the back panel grabbing driving assembly 302 drives the back panel clamping claw 301 to move upward, so that the end of the back panel is lifted from the glass, and then the back panel peeling driving assembly 305 drives the second peeling roller assembly 304 to approach the first peeling roller assembly 303 and clamp the back panel between the two peeling roller assemblies, and finally the back panel peeling transmission mechanism 300 resumes work and continues to transmit the photovoltaic module, and the first peeling roller assembly 303 drives the second peeling roller assembly 304 to rotate and completely peel the back panel from the glass, and manual or robotic assistance can be provided when peeling the back panel.

[0136] The backplane peeling device 3 of the second embodiment of the present invention adopts the following structure:

[0137] The backplane stripping device 3 includes a backplane stripping workbench 306, a backplane stripping mounting frame 307, a backplane stripping transmission mechanism 300 and a backplane grabbing mechanism. The backplane stripping transmission mechanism 300 and the backplane stripping mounting frame 307 are both installed on the backplane stripping workbench 306, the backplane stripping mounting frame 307 is located above the backplane stripping transmission mechanism 300, and the backplane grabbing mechanism is installed on the backplane stripping mounting frame 307. The backplane stripping transmission mechanism 300 is used to transport the photovoltaic module, and the backplane stripping workbench 306 is equipped with a corresponding sensor. When the photovoltaic module reaches a predetermined position, the sensor is triggered, and the backplane stripping transmission mechanism 300 stops working. The backplane grabbing mechanism is used to grab the end of the backplane of the photovoltaic module and drive the backplane to completely strip the glass.

[0138] The structures of the various mechanisms in this embodiment can refer to the first embodiment. The difference is that in this embodiment, the stroke of the backplane clamp 301 in the backplane peeling transmission mechanism 300 needs to be greater than the length of the backplane. This embodiment does not adopt a backplane peeling mechanism, but the backplane grasping mechanism directly clamps the backplane and completely peels off the backplane.

[0139] It should be noted that the backboard grabbing mechanism in this embodiment may only have a lifting function, or may be designed as a structure with forward, backward, left and right movement functions.

[0140] The second heating device 8 in the present invention includes a second heating transmission mechanism and a second high-temperature tunnel furnace, the second heating transmission mechanism is used to transmit the photovoltaic module, and the second high-temperature tunnel furnace is used to heat the photovoltaic module at high temperature. The structure of the second heating device 8 is the same as that of the first heating device 1, and will not be repeated.

[0141] like Figure 14-16 As shown, the cell removal device 4 includes a cell removal workbench 414, on which a cell removal transmission mechanism 411, a cell removal limiting mechanism and a cell scraping mechanism are installed. The cell removal transmission mechanism 411 is used to transport the photovoltaic module, the cell removal limiting mechanism is used to limit the photovoltaic module so that the photovoltaic module remains stationary when the cell is removed, and the cell scraping mechanism includes a scraper driving assembly and a scraper 400, the scraper driving assembly is used to drive the scraper 400 to move, and the scraper 400 is used to scrape the cells on the photovoltaic module.

[0142] It can be understood that in the above technical scheme, the present invention is provided with a cell removal transmission mechanism 411, a cell removal limiting mechanism, a cell scraping mechanism and other mechanisms, which can realize the automatic transmission, automatic limiting and automatic scraping of photovoltaic modules. The structural design is reasonable, the operation is stable, the work is efficient, and the economic benefits of the enterprise can be improved.

[0143] Continue reading Fig.14 The cell removal and transmission mechanism 411 of the present invention adopts a conveyor belt, which is used to support and drive the photovoltaic module forward. In addition, the cell removal and transmission mechanism 411 can also adopt mechanisms such as roller conveyors.

[0144] Further reading Fig.14 An auxiliary guide wheel 12 is set at the end of the cell removal transmission mechanism 411. The upper end height of the auxiliary guide wheel 12 is based on being flush with the conveyor belt. It plays a role in auxiliary support of the photovoltaic module, so that the photovoltaic module can leave the cell removal workbench 414 more smoothly.

[0145] Continue reading Fig.15 The blade driving assembly includes a blade lifting module and a blade forward and backward moving module. The blade lifting module is used to drive the blade 400 to lift and lower, and the blade forward and backward moving module is used to drive the blade 400 to move forward and backward.

[0146] Among them, the scraper forward and backward movement module includes a scraper forward and backward movement frame 401, two left and right scraper forward and backward movement slide rails 403, a scraper forward and backward movement tooth plate 404, a scraper forward and backward movement gear 405 and a scraper forward and backward movement motor 406. The scraper forward and backward movement slide rails 403 and the scraper forward and backward movement tooth plate 404 are arranged on the battery cell removal workbench 414 along the front and rear direction. The scraper forward and backward movement tooth plate 404 is close to one of the scraper forward and backward movement slide rails 403. The scraper forward and backward movement frame 401 is arranged along the left and right direction, and its left and right ends are respectively slidably matched with the two scraper forward and backward movement slide rails 403 through the scraper forward and backward movement slide seat 413. The scraper forward and backward movement motor 406 is installed on the scraper forward and backward movement frame 401 close to one end of the scraper forward and backward movement tooth plate 404. The output shaft of the scraper forward and backward movement motor 406 is directly connected to the scraper forward and backward movement gear 405, and the two can also be connected through structures such as pulleys and intermediate gears. The scraper forward and backward movement gear 405 is meshed with the scraper forward and backward movement tooth plate 404. The blade lifting module is installed on the blade forward and backward moving module, which includes a blade lifting driver 402 arranged on the blade forward and backward moving frame 401. The blade lifting driver 402 is connected with the blade 400 to drive the blade 400 to rise and fall.

[0147] Further reading Fig.15 and Fig.16 The number of the blade lifting driver 402 and the blade 400 of the present invention is greater than 1, all the blade lifting drivers 402 are arranged at intervals along the left-right direction at the upper end of the blade forward and backward moving frame 401, the lower end of the blade forward and backward moving frame 401 has a blade seat 408, the upper part of the blade seat 408 is fixedly connected to a plurality of blade seat slide rods 415, the blade seat slide rods 415 are connected to the blade forward and backward moving frame 401 for vertical sliding connection, the upper end of the blade seat 408 is connected to the output end of all the blade lifting drivers 402, and all the blades 400 are arranged at intervals along the left-right direction at the lower end of the blade seat 408.

[0148] When the blade driving assembly is working, on the one hand, the blade forward and backward moving motor 406 drives the blade forward and backward moving gear 405 to rotate, so that the blade forward and backward moving gear 405 moves forward and backward on the blade forward and backward moving gear plate 404, and drives the blade forward and backward moving frame 401 and the components thereon to move forward and backward, thereby realizing the forward and backward movement function of the blade 400; on the other hand, the blade lifting driver 402 drives the blade 400 to rise and fall through the blade seat 408, thereby realizing the lifting function of the blade 400.

[0149] The blade lifting driver 402 is preferably a pneumatic cylinder, and other driving structures such as an electric cylinder, an oil cylinder, a slide, etc. may also be used.

[0150] Among them, the scraper blade moving forward and backward module can also adopt structures such as a slide.

[0151] Furthermore, the present invention arranges a plurality of blade return springs 407 between the blade 400 and the blade front and rear moving frame 401. The blade return springs 407 can help the blade 400 to return to its original position, which is more labor-saving.

[0152] like Fig.14 As shown, the cell removal limit mechanism is arranged at the rear end of the cell removal workbench 414, which includes a cell removal limit baffle 409 and a cell removal limit baffle driver 410. The cell removal limit baffle 409 is used to block the advancement of the photovoltaic module, and the cell removal limit baffle driver 410 is used to drive the cell removal limit baffle 409 to move, so that the cell removal limit baffle 409 comes to the position of blocking the photovoltaic module, or leaves the position of blocking the photovoltaic module.

[0153] The cell removal limit baffle driver 410 is preferably a cylinder, and the output end is directly connected to the cell removal limit baffle 409, driving the cell removal limit baffle 409 to rise and fall. When the cell removal limit baffle 409 rises, the cell removal limit baffle 409 can block the photovoltaic module from moving forward. When the cell removal limit baffle 409 falls, the cell removal limit baffle 409 no longer blocks the photovoltaic module. In addition, the cell removal limit baffle driver 410 can also use an oil cylinder or an electric cylinder. In addition to rising and falling, the cell removal limit baffle 409 can also block the photovoltaic module by moving horizontally.

[0154] Working process of the battery cell removal device 4:

[0155] The photovoltaic component (which can be placed on a tray) enters the cell removal device 4 after being heated by the second heating device 8, and is transported backward by the cell removal transmission mechanism 411. When the sensor senses that the photovoltaic component is approaching, the cell removal limit baffle 409 rises to prevent the photovoltaic component from moving further forward, and then the scraper drive assembly drives the scraper 400 to move to remove the cells on the photovoltaic component.

[0156] The disassembly system for recycling photovoltaic modules of the present invention is also equipped with a loading device 5 and a unloading device 9, both of which are manipulator devices.

[0160] Step 2, removing the frame of the photovoltaic module by the frame removal device 7, and transferring the photovoltaic module to the back panel edge device 2 after removal. The front and rear transfer of the photovoltaic module in the frame removal step can be achieved manually or by a robot;
