It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] A photovoltaic panel includes a backsheet and a glass layer bonded to the backsheet with an adhesive. This embodiment provides a photovoltaic panel dismantling device that can accurately dismantle the backsheet and glass layer, with high dismantling efficiency, and can also effectively avoid structural damage to the backsheet, thereby improving resource reuse rate.

[0033] Please see Figures 1 to 5 The photovoltaic panel dismantling device includes a conveying module, a heating module, and a dismantling module. The photovoltaic panel with its frame removed is used as the photovoltaic panel to be dismantled. The photovoltaic panel to be dismantled is placed with the glass layer facing down and is conveyed to the dismantling module by the conveying module. During the conveying process, the heating module heats the panel, causing the colloid between the glass layer and the backsheet to melt, so that the glass layer can be cut off later. After the photovoltaic panel reaches the dismantling module, the dismantling module crushes and cuts off the glass layer, and finally the backsheet is recycled. The dismantling efficiency is high, and the process does not cause structural damage to the backsheet, thus improving the resource reuse rate.

[0034] For example, please refer to Figure 1 and Figure 3 The conveying module includes a frame 11 and a conveyor belt 12. The conveyor belt 12 is mounted on the frame 11 and is arranged along a first direction. The conveyor belt 12 rotates to convey the photovoltaic panels to be disassembled.

[0035] In some feasible embodiments, the conveying module further includes a drive structure and two active rollers 13, which are mounted at intervals on the frame 11 along a first direction. The conveyor belt 12 is wound around the two active rollers 13. The drive structure is used to drive the two active rollers 13 to rotate synchronously in the same direction, thereby driving the conveyor belt 12 to rotate along the first direction and conveying the photovoltaic panels to be disassembled on it.

[0036] For example, please refer to Figures 1 to 3 The heating module includes a heating tube 21, which is mounted on the frame 11. After disassembly begins, the heating tube 21 is energized and heats up, thereby heating the photovoltaic panel to be disassembled, causing the colloid between the glass layer and the backsheet to melt, so that the glass layer can be cut off later.

[0037] Optionally, the heating tube 21 is an infrared heating tube 21, which performs directional heat radiation by releasing infrared rays to heat the photovoltaic panel to be disassembled.

[0038] Furthermore, the heating module also includes a heat-insulating top cover 22 for providing heat preservation. Specifically, the heat-insulating top cover 22 is mounted on the frame 11 via a conventional bracket, and the heat-insulating top cover 22 is positioned above the conveyor belt 12. Preferably, the orthogonal projection of the heat-insulating top cover 22 covers the conveyor belt 12, and the heating pipe 21 is installed on the side of the heat-insulating top cover 22 near the conveyor belt 12.

[0039] Furthermore, the heating module also includes two vertically arranged guard plates 23, which are respectively installed on both sides of the frame 11 along the first direction. The guard plates 23 are arranged along the first direction and extend from one end of the conveyor belt 12 to the opposite end. Preferably, the guard plates 23 are higher than the heat insulation top cover 22 to improve the heat preservation effect.

[0040] Optionally, both the heat-insulating top cover 22 and the protective panel 23 are made of heat-insulating materials.

[0041] With the above setup, the photovoltaic panel to be cut is heated by the heating pipe 21 above the conveyor belt 12 during transportation, which melts the colloid between the glass layer and the back sheet, so that the glass can be scraped off later. During the heating process, the heat insulation top cover 22 and the protective plate 23 provide heat preservation measures.

[0042] Please see Figures 1 to 3 The removal module is located on one side of the frame 11 along the first direction, that is, at the outlet of the conveyor belt 12, so that the glass layer and the back plate can be removed after the colloid between the glass layer and the back plate melts.

[0043] For example, the dismantling module includes a support frame 31, a set of extrusion rollers, and a set of blades. The support frame 31 is located on one side of the frame 11 along the first direction, that is, at the outlet of the conveyor belt 12. The extrusion rollers and the set of blades are both mounted on the support frame 31, and the set of blades is located on the side of the extrusion rollers away from the support frame 31. The extrusion rollers are used to extrude the photovoltaic panel to be dismantled, thereby crushing the glass layer into glass fragments. The set of blades is used to scrape off the glass fragments.

[0044] Specifically, please refer to Figure 3 The extrusion roller assembly includes two pressure rollers 32, which are spaced apart vertically and rotatably mounted on a support frame 31. During disassembly, the two pressure rollers 32 rotate in opposite directions, providing power to the photovoltaic panel to be disassembled, allowing it to be disassembled under the action of the blade assembly. With this configuration, the photovoltaic panel to be cut enters the gap between the two pressure rollers 32 under the conveyor belt 12, where it is squeezed and crushed into glass fragments.

[0045] Specifically, the blade assembly includes blades 33 arranged along a first direction, with the blade tip extending into the gap between two pressure rollers 32. The two pressure rollers 32 rotate in opposite directions to provide power to the photovoltaic panel to be disassembled, so that the blade tip can cut off glass fragments located in the lower layer.

[0046] Preferably, the blade assembly includes a plurality of blades 33 spaced apart along the width of the conveyor belt 12 to scrape away the glass fragments under the back plate and improve the disassembly effect.

[0047] In this embodiment, the photovoltaic panel dismantling device also includes a glass recycling module for recycling the cut-off glass fragments. For example, please refer to... Figure 3 The glass recycling module includes a guide hopper 41 and a recycling bin 42. The guide hopper 41 is positioned directly below the pressure roller 32, and the orthographic projection of the pressure roller 32 falls on the upper opening of the guide hopper 41, ensuring that it can catch falling glass fragments. The lower opening of the guide hopper 41 extends into the recycling bin 42. With the above configuration, the photovoltaic panel to be cut is conveyed by the conveyor belt 12 and squeezed between the two pressure rollers 32. The glass layers are squeezed and crushed into fragments. The blade 33 scrapes off the glass fragments located in the lower layer. The glass fragments can fall directly into the upper opening of the guide hopper 41 and be collected in the recycling bin 42 for easy transfer.

[0048] Preferably, the cross-sectional shape of the guide hopper 41 is an inverted trapezoid, that is, the cross-sectional area of ​​the guide hopper 41 gradually decreases from top to bottom, which facilitates the collection of glass fragments.

[0049] The photovoltaic panel dismantling device provided in this embodiment also includes a backsheet recycling module for recycling the backsheet. For example, the backsheet recycling module includes a set of discharge rollers 51, which comprises several discharge rollers 51 spaced apart along a first direction. The discharge rollers 51 extend from one end of the conveyor belt 12 in the width direction to the other end. The discharge rollers 51 are rotatably mounted on the support frame 31 via a conventional bracket, and the discharge rollers 51 are higher than the blade 33. The set of discharge rollers 51 is positioned close to the handle of the blade 33. That is, the backsheet slides above the blade 33 under the drive of two pressure rollers 32, and during the sliding process, the several discharge rollers 51 are driven to rotate sequentially, guiding the backsheet.

[0050] With the above configuration, the back plate slides above the blade 33 under the drive of the two pressure rollers 32, and drives several discharge rollers 51 to rotate in sequence during the sliding process. The discharge rollers 51 guide the back plate to be transported to the discharge channel 6 located on the side of the support frame 31 away from the frame 11.

[0051] Optionally, at least one discharge roller 51 is located directly above the blade 33 to ensure a guiding effect on the back plate.

[0052] Preferably, please refer to Figure 4The top of the cutter head is provided with a ramp 331, and the end of the ramp 331 near the pressure roller 32 is lower than the end away from the pressure roller 32, so that the back plate can slide above the blade 33 under the guidance of the ramp 331.

[0053] The backplate recycling module also includes a guide plate 52 arranged along the first direction. The guide plate 52 extends from one end of the conveyor belt 12 in the width direction to the other end, and is used to further limit and guide the backplate.

[0054] Optionally, please refer to Figure 3 and Figure 5 The guide plate 52 includes a first plate 521, a second plate 522, and a third plate 523 connected together. The first plate 521 is close to the pressure roller 32 and is inclined. One end of the first plate 521 near the pressure roller 32 is flush with the bottom of the discharge roller 51. Because the back plate is tilted upwards at the front end under the guidance of the ramp 331, the end of the first plate 521 near the pressure roller 32 can limit the back plate and ensure its smooth transport. Furthermore, the other end of the first plate 521 is higher than the discharge roller 51 group and connected to the second plate 522. One end of the second plate 522 is connected to one end of the third plate 523. The orthographic projection of the second plate 522 covers the discharge roller 51 group. The third plate 523 is set at an angle and the other end of the third plate 523 is lower than one end of the third plate 523. The other end of the third plate 523 is set lower than the top of the discharge roller 51 to ensure that the back plate is in a state of front-end falling under the action of the third plate 523, so that the back plate can fall smoothly into the discharge channel 6 located on the side of the support frame 31 away from the frame 11 after it is separated from the discharge roller 51.

[0055] The extrusion roller assembly provided in this embodiment also includes an adjustment frame 34. Both pressure rollers 32 are mounted on the adjustment frame 34. The adjustment frame 34 is height-adjustable and mounted on the support frame 31, which facilitates the extrusion of photovoltaic panels of different thicknesses to be disassembled.

[0056] The extrusion roller assembly also includes an adjustment component for adjusting the height of the adjustment frame 34. The adjustment component includes a connecting plate 35, several screws 36, and several elastic elements 37. The connecting plate 35 is mounted on the bottom of the adjustment frame 34. The connecting plate 35 has several mounting holes spaced circumferentially. Each mounting hole, screw 36, and elastic element 37 corresponds to a specific screw. One end of each screw 36 is inserted into the corresponding mounting hole and screwed onto the support frame 31. The elastic element 37 is fitted onto the corresponding screw 36 and abuts against the connecting plate 35 and the support frame 31. With this configuration, the height of the connecting plate 35 can be adjusted by turning the screws 36, thus achieving height adjustment of the adjustment frame 34.

[0057] The blade assembly provided in this embodiment also includes a sliding blade holder (not shown in the figure), and the blade 33 is mounted on the sliding blade holder. The sliding blade holder is used to adjust the height of the blade 33 to adapt to photovoltaic panels of different thicknesses to be disassembled.

[0058] The sliding tool holder includes a base, a rack, a clamp, a gear, and a feed handwheel. The base is mounted on a support frame 31. The rack is slidably mounted on the support frame 31 along a first direction. The clamp is mounted on the rack, and the cutting tool 33 is clamped in the clamp. The gear meshes with the rack. Preferably, the feed handwheel is fixed to the shaft of the gear. With the above configuration, rotating the feed handwheel drives the rack, thereby adjusting the height of the clamp and the cutting tool 33 on it.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
