[0057] Reference Figures 1 to 7 , is a photovoltaic module silicon wafer structure separation device in some embodiments of the present invention, the silicon wafer structure is a complete glass component or a broken glass component, specifically, the silicon wafer structure is a structure composed of tempered glass, EVA adhesive layer and battery panel, and the tempered glass is connected to the battery panel through the EVA adhesive layer.

[0058] like Figure 1As shown, the photovoltaic module silicon wafer structure separation device includes a support frame 1, an overall transmission mechanism 2, a hot knife separation mechanism 3, a complete panel transmission mechanism 4, a complete glass transmission mechanism 5, a broken glass processing mechanism 6, a broken glass transmission mechanism 7 and a broken panel transmission mechanism 8. The overall transmission mechanism 2 is connected to the support frame 1. The support frame 1 has a first position and a second position. The setting height of the first position is greater than the setting height of the second position. The overall transmission mechanism 2 can move along the height direction of the support frame 1 between the first position and the second position. When the overall transmission mechanism 2 is in the first position, the overall transmission mechanism 2 is used to transmit the complete glass component. When the overall transmission mechanism 2 is in the second position, the overall transmission mechanism 2 is used to transmit the broken glass component. The operator can choose the lifting and lowering of the overall transmission mechanism 2 by judging the quality of the glass of the silicon wafer structure, so as to perform different treatments on the complete glass component and the broken glass component. Figure 1 As shown, the integral transmission mechanism 2 is located in the first position.

[0059] Furthermore, the hot knife separation mechanism 3 is connected to the support frame 1 and is arranged corresponding to the first position, and the hot knife separation mechanism 3 is used to separate the complete glass assembly into complete glass and complete battery panels; the complete battery panel transmission mechanism 4 is connected to the support frame 1, and is used to transmit the complete battery panels separated by the hot knife separation mechanism 3; the complete glass transmission mechanism 5 is connected to the support frame 1, and is used to transmit the complete glass separated by the hot knife separation mechanism 3; the broken glass processing mechanism 6 is connected to the support frame 1 and is arranged corresponding to the second position, and the broken glass processing mechanism 6 is used to separate the broken glass assembly into broken glass and broken battery panels; the broken glass transmission mechanism 7 is connected to the support frame 1, and is used to transmit the broken glass separated by the broken glass processing mechanism 6; the broken battery panel transmission mechanism 8 is connected to the support frame 1, and is used to transmit the broken battery panels separated by the broken glass processing mechanism 6.

[0060] As can be understood, the photovoltaic module silicon wafer structure separation device utilizes an integrated conveyor mechanism 2 connected to a support frame 1. The integrated conveyor mechanism 2 can move between a first position and a second position along the height of the support frame 1. The operator can determine the quality of the glass in the silicon wafer structure by adjusting the level of the integrated conveyor mechanism 2, thereby performing different treatments on the intact glass and broken glass components. Furthermore, the hot knife separation mechanism 3 separates the intact glass components into intact glass and intact panels, while the broken glass processing mechanism 6 separates the broken glass components into broken glass and broken panels. This enables complete separation of the silicon wafer structure, enabling efficient and accurate recovery of key materials and reducing the cost of subsequent processes. Furthermore, the efficiency of the hot cutting significantly increases the speed of silicon wafer structure separation, avoiding the drawbacks of traditional processes such as incomplete and fragmented separation of silicon wafer structures. Furthermore, a complete panel conveyor mechanism 4, a complete glass conveyor mechanism 5, a broken glass conveyor mechanism 7, and a broken panel conveyor mechanism 8 are provided to collect the separated intact panels, intact glass, broken glass, and broken panels to different locations, respectively, thereby improving the conveyor speed and operating efficiency of the photovoltaic module silicon wafer structure separation device.

[0061] In this embodiment, the intact panel conveyor mechanism 4, intact glass conveyor mechanism 5, and broken panel conveyor mechanism 8 are arranged sequentially along the height direction of the support frame 1 from top to bottom. The intact panel conveyor mechanism 4 is inclined relative to the horizontal plane, preferably at an angle of 15°. The intact glass conveyor mechanism 5 and the broken panel conveyor mechanism 8 are both arranged parallel to the horizontal plane. The overall conveyor mechanism 2, the intact panel conveyor mechanism 4, the intact glass conveyor mechanism 5, the broken glass conveyor mechanism 7, and the broken panel conveyor mechanism 8 all utilize belt lines for transmission. The belt lines of these conveyor mechanisms are all made of polyurethane. The maximum effective width of the belt lines of the overall conveyor mechanism 2, the intact panel conveyor mechanism 4, the intact glass conveyor mechanism 5, and the broken panel conveyor mechanism 8 is 1200 mm, and the maximum effective width of the belt line of the broken glass conveyor mechanism 7 is 350 mm.

[0062] like Figure 2As shown, the photovoltaic module silicon wafer structure separation device also includes a lifting transmission mechanism 91, which includes a linked screw elevator 911, a lifting guide rail 912, and a lifting slider 913. The linked screw elevator 911 is connected to the support frame 1 and is in transmission connection with the overall transmission mechanism 2. The lifting guide rail 912 is connected to the support frame 1. The lifting slider 913 is movably connected to the lifting guide rail 912, and the overall transmission mechanism 2 is connected to the lifting slider 913. It can be understood that the linked screw elevator 911 can be driven by a servo motor to lift the screw, and the lifting function of the overall transmission mechanism 2 is achieved by guiding the lifting slider 913 and the lifting guide rail 912. After the overall transmission mechanism 2 descends to the second position, it docks with the broken glass processing mechanism 6. After it rises to the first position, it docks with the hot knife separation mechanism 3.

[0063] Furthermore, the photovoltaic module silicon wafer structure separation device also includes a centering mechanism 96, which includes a centering member 961 connected to the overall conveying mechanism 2 and a centering cylinder 962 connected to the overall conveying mechanism 2. The centering cylinder 962 cooperates with the centering member 961 to ensure the centering of the silicon wafer structure during input. The centering member 961 is also provided with a centering adjustment hole to facilitate position adjustment on the overall conveying mechanism 2. In this embodiment, there are three centering members 961, and the centering cylinder 962 cooperates with one of the centering members 961. It can be understood that the centering mechanism 96 can achieve the centering position of the entire silicon wafer structure in the width direction, ensuring the centering position of the entire silicon wafer structure on the overall conveying mechanism 2. The overall conveying mechanism 2 may also be provided with a laser sensor to detect whether a silicon wafer structure is present on the overall conveying mechanism 2 or whether a silicon wafer structure has been transferred out of the overall conveying mechanism 2.

[0064] like Figures 3 to 5 As shown, the hot knife separation mechanism 3 includes a separation positioning frame 31, multiple support roller assemblies 32, and multiple pressure roller assemblies 33. The separation positioning frame 31 is connected to the support frame 1, and each support roller assembly 32 includes a support roller member 321 that is movably connected to the separation positioning frame 31 and a support roller linkage 322 connected to the support roller member 321. The support roller member 321 and the support roller linkage 322 are fixedly connected. The support roller member 321 can drive the entire silicon wafer structure before separation into the hot knife separation mechanism 3, or drive the complete solar cell panel and complete glass after separation into subsequent mechanisms.

[0065] Each pressing roller assembly 33 includes a pressing roller member 331, a pressing connecting member 332, a pressing abutment member 333, a pressing fixing member 334, a pressing guide member 335 and a pressing elastic member 336. The pressing roller member 331 and the pressing abutment member 333 are commonly connected to the pressing connecting member 332. The pressing connecting member 332 is movably connected to the pressing guide member 335. The pressing fixing member 334 is fixedly connected to the separation positioning frame 31. The pressing guide member 335 is connected to the pressing fixing member 334. The pressing elastic member 336 is sleeved on the outside of the pressing guide member 335. The first end of the pressing elastic member 336 is connected to the pressing connecting member 332, and the second end of the pressing elastic member 336 is connected to the pressing fixing member 334.

[0066] It is understood that the pressing connector 332 can be connected to the pressing roller 331 via a bearing, and the pressing abutment 333 can be connected to the pressing connector 332 via a bolt. The pressing roller 331 and the pressing abutment 333 cooperate with the support roller 321 to compress the silicon wafer structure, ensuring friction between the silicon wafer structure and the support roller 321, while flattening the silicon wafer structure and ensuring more accurate separation of the hot knife assembly 34. In this embodiment, the pressing abutment 333 is made of a spring sheet. The pressing roller 331 is connected to the middle of the pressing connector 332, and two pressing abutment 333 are located on either side of the pressing roller 331. The use of spring sheets on both sides of the pressing roller 331 to compress the photovoltaic module can avoid the drawback of a small contact area and limited flattening effect caused by the presence of a potential adhesive layer on the edge of the silicon wafer structure.

[0067] In addition, the upper portion of the pressing guide 335 can be threadedly connected to the pressing fixing member 334, while the lower portion of the pressing guide 335 is inserted into the pressing connecting member 332. The pressing elastic member 336 can be a spring. The configuration of the pressing elastic member 336 can enable the pressing roller assembly 33 to adaptively adjust according to the thickness of different photovoltaic modules, ensuring that the pressing abutment member 333 and the pressing roller member 331 can press against the photovoltaic module.

[0068] Furthermore, the hot knife separation mechanism 3 also includes a hot knife assembly 34, which includes a separation positioning piece 341 connected to the separation positioning frame 31, a separation connecting frame 342 connected to the separation positioning piece 341, a blade rack 343 connected to the separation connecting frame 342, a tool 344 connected to the blade rack 343, an electric heating wire installed in the blade rack 343, and a pressure block 345. The pressure block 345 is respectively connected to the tool 344 and the blade rack 343, and the upper end surface of the pressure block 345 is inclined relative to the horizontal plane of the blade rack 343.

[0069] Specifically, the cutter 344 is secured to the blade holder 343 via bolts and a pressure block 345. The cutter 344 is replaceable from the side, while the separation locator 341 can be adjusted relative to the separation locator 31. Adjusting the position of the separation locator 341 simultaneously adjusts the height and angle of the blade holder 343 and cutter 344, facilitating alignment of the cutting edge of the cutter 344 with the adhesive layer between the backplane and the silicon wafer. When energized, the electric heating wire generates heat that first heats the blade holder 343 and then transfers it to the cutter 344. Ultimately, the cutting edge of the cutter 344 reaches a temperature of 100°C, softening the adhesive layer without melting it. The softened adhesive layer is then cut, separating the panel from the glass. The pressure block 345 has a triangular cross-section, with its upper end tilted relative to the horizontal plane of the blade holder 343. After separation of the panel from the glass, the backplane can be moved along the upper end of the pressure block 345 into the subsequent storage space.

[0070] like Figure 5 As shown, the hot knife separation mechanism 3 also includes a separation guide assembly 35 and a separation transmission assembly 36. The separation guide assembly 35 includes an upper guide plate 351, a lower guide plate 352, a complete glass guide plate 353, and a pressing and retaining member 354. The upper guide plate 351 and the lower guide plate 352 are both connected to the separation positioning frame 31 and are inclined relative to the horizontal plane of the separation positioning frame 31. A space is formed between the upper guide plate 351 and the lower guide plate 352 for the complete solar panel to pass through after separation. The space is arranged corresponding to the upper end surface of the pressing block 345. The complete glass guide plate 353 is arranged parallel to the separation positioning frame 31 and is used to guide the complete glass after separation. The complete glass transmission mechanism 5 is arranged corresponding to the complete glass guide plate 353. The pressing and fixing member 354 is connected to the separation and positioning frame 31 . The pressing and fixing member 354 is corresponding to the accommodating space and is used to press on the complete solar panel after separation. The complete solar panel transmission mechanism 4 is corresponding to the pressing and fixing member 354 .

[0071] As can be understood, the accommodation space formed between the upper guide plate 351 and the lower guide plate 352 allows for the passage of the separated complete panel, thereby providing guidance for the separated complete panel and facilitating the docking of the separated complete panel with the complete panel transport mechanism 4. The separated complete glass moves along the lower end surface of the complete glass guide plate 353, with a space for the complete glass to pass through formed between the complete glass guide plate 353 and the support roller member 321. Furthermore, the clamping member 354 is specifically configured to cooperate with one of the support roller members 321 to position and clamp the separated complete panel.

[0072] like Figure 3As shown, the separation transmission assembly 36 includes a separation transmission driver 361 connected to the separation positioning frame 31 and a separation transmission member 362 connected to the output end of the separation transmission driver 361. The separation transmission member 362 is simultaneously in transmission connection with multiple support roller linkages 322. The separation transmission driver 361 can be a speed-controlled motor, and the separation transmission member 362 can be a chain. The speed-controlled motor can be in transmission connection with the multiple support roller linkages 322 via the chain to achieve fully synchronous transmission.

[0073] like Figure 6 and Figure 7 As shown, the broken glass processing mechanism 6 includes a crushing positioning frame 61, a plurality of crushing guide roller assemblies 62, a plurality of crushing positioning roller assemblies 63, and a plurality of crushing action roller assemblies 64. The crushing positioning frame 61 is connected to the support frame 1.

[0075] It can be understood that the crushing guide rollers 621 and the crushing positioning rollers 631 are used together to flatten and convey the broken glass assemblies, while the crushing portion 6411 provided on the crushing action roller 641 is used to crush the glass in the broken glass assemblies, separating the crushed glass from the solar panels at different rotational speeds. In this embodiment, there are four crushing guide rollers 621, two crushing positioning rollers 631, and two crushing action rollers 641. Two crushing guide rollers 621 are located below the crushing positioning frame 61 on either side, while two crushing positioning rollers 631 are located above the crushing positioning frame 61 on either side. In other words, the crushing positioning rollers 631 are also located above the two crushing guide rollers 621. The other two crushing guide rollers 621 are located above the center of the crushing positioning frame 61, while the two crushing action rollers 641 are located below the two crushing guide rollers 621. As the broken glass assembly passes through the crushing guide roller 621 and the crushing positioning roller 631, the crushing positioning roller 631, under the action of the crushing positioning elastic member 633, flattens the broken glass assembly, thereby increasing the transmission force of the broken glass processing mechanism 6. The crushing action portion 6411 is specifically a groove structure. As the broken glass assembly passes through, it is squeezed by the crushing guide roller 621 and the crushing action roller 641, crushing the glass. The separated broken glass falls below, while the broken solar panels with glass fragments are transported to the broken solar panel transmission mechanism 8. The crushing action roller 641, under the action of the crushing action elastic member 643, can continuously compress the broken glass assembly, reducing the amount of residual broken glass.

[0076] The broken glass processing mechanism 6 also includes a crushing guide transmission assembly 65 and a crushing action transmission assembly 66. The crushing guide transmission assembly 65 includes a crushing guide driver 651 connected to the crushing positioning frame 61 and a crushing guide transmission member 652 connected to the output end of the crushing guide driver 651. The crushing guide transmission member 652 is also in driving connection with multiple crushing guide roller linkages 622 and multiple crushing positioning linkages 635. The crushing action transmission assembly 66 includes a crushing action driver 661 connected to the support frame 1 and a crushing action transmission member 662 connected to the output end of the crushing action driver 661. The crushing action transmission member 662 is also in driving connection with multiple crushing action linkages 645.

[0077] The crushing guide driver 651 and the crushing action driver 661 can both be speed-controlled motors, and the crushing guide transmission member 652 and the crushing action transmission member 662 can both be chains. The crushing guide transmission member 652 is simultaneously connected to the multiple crushing guide roller linkages 622 and the multiple crushing positioning linkages 635, allowing the multiple crushing guide roller linkages 622 and the multiple crushing positioning linkages 635 to transmit synchronously. The crushing action transmission member 662 is simultaneously connected to the multiple crushing action roller linkages 642, allowing the multiple crushing action linkages 645 to move synchronously. The rotation speed of the crushing action linkages 645 is faster than that of the crushing guide roller linkages 622 and the crushing positioning linkages 635, allowing the crushed glass to be separated from the solar panels during rapid rotation.

[0078] like Figure 1 As shown, the broken glass processing mechanism 6 further includes a hollow connecting member 67 connected below the crushing positioning frame 61. The broken glass conveying mechanism 7 is provided corresponding to the hollow connecting member 67. The photovoltaic module silicon wafer structure separation device also includes a broken glass collection box 92 provided corresponding to the broken glass conveying mechanism 7. The broken glass collection box 92 is used to collect the broken glass conveyed by the broken glass conveying mechanism 7. Specifically, the hollow connecting member 67 is funnel-shaped. After passing through the hollow connecting member 67, the broken glass is conveyed by the belt line of the broken glass conveying mechanism 7 to the broken glass collection box 92 for collection.

[0079] like Figure 1As shown, the photovoltaic module silicon wafer structure separation device also includes a material storage rack 93 and a lifting trolley 94. The material storage rack 93 is used to receive intact panels conveyed by the intact panel conveyor 4, intact glass conveyed by the intact glass conveyor 5, and broken panels conveyed by the broken panel conveyor 8. The lifting trolley 94 is used to temporarily receive intact panels conveyed by the intact panel conveyor 4, intact glass conveyed by the intact glass conveyor 5, and broken panels conveyed by the broken panel conveyor 8. It is understood that a discharge plate corresponding to the above-mentioned conveyor mechanism is provided on the material storage rack 93 at a corresponding height to accommodate intact panels, intact glass, and broken panels. The lifting trolley 94 can also be a scissor-type lifting trolley 94. When intact panels, intact glass, or broken panels need to be transferred, the lifting trolley 94 can be adjusted to an appropriate height to dock the intact panels, intact glass, or broken panels.

[0080] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention.
