Description

Technical Field

[0001] This invention relates to the field of photovoltaic module recycling equipment, and more specifically, to a solar laminate stripping device. Background Technology

[0002] Most materials used in photovoltaic (PV) modules are recyclable, with silicon, copper, glass, backsheet, and EVA having significant recycling value. Recycling PV modules saves resources, reduces the extraction of natural resources, and lowers the energy consumption of resource refining, thereby mitigating environmental impact and damage. One existing technology involves a method for separating and recycling PV laminates. This method involves fixing the PV laminate to be processed, rubbing the backsheet to break it, and separating the backsheet from the PV laminate. The broken backsheet particles are then recovered. The PV laminate without the backsheet is then broken down, screened, and separated to obtain the separated glass, EVA, and silicon solar cells, thus completing the separation and recycling of the PV laminate. However, this method is only suitable for PV modules with intact glass surfaces; it cannot disassemble PV modules with broken glass surfaces.

[0003] Furthermore, current recycling methods only address the issue of whether the tempered glass in the solar laminate is broken or not after removing the frame and junction box of the solar module. Regardless of the glass condition, this method cannot effectively separate the backsheet, EVA, battery materials, and glass components. Manually peeling the solar laminate is labor-intensive, ineffective, and can easily cause injuries such as cuts.

[0004] Therefore, existing technologies suffer from problems such as difficulty in recycling photovoltaic modules and low efficiency. Summary of the Invention

[0005] The main objective of this invention is to provide a solar laminate stripping device to solve the problems of difficult and inefficient recycling of photovoltaic modules in the prior art.

[0006] To achieve the above objectives, according to one aspect of the present invention, a solar laminate stripping device is provided, comprising a stripping platform and a stripping structure, the stripping structure being located above the stripping platform, and a stripping space being provided between the stripping structure and the stripping platform. The stripping structure includes: a horizontal stripping assembly having at least one horizontal stripping cutter; and a vertical stripping assembly having at least one vertical stripping cutter, the rotation axis of the horizontal stripping cutter being perpendicular to the rotation axis of the vertical stripping cutter, the distance from the horizontal stripping cutter to the stripping platform being greater than the distance from the vertical stripping cutter to the stripping platform, and the horizontal stripping assembly and the vertical stripping assembly being interconnected and arranged sequentially along a first direction, wherein when the stripping structure moves relative to the stripping platform along the first direction, the vertical stripping assembly is located upstream of the horizontal stripping assembly.

[0007] Furthermore, the horizontal peeling assembly includes a first peeling housing having a first receiving cavity and a first peeling opening facing the peeling platform and communicating with the first receiving cavity, and at least a portion of the horizontal peeling cutter is rotatably disposed inside the first receiving cavity.

[0008] Furthermore, there are multiple horizontal peeling tools, which are spaced apart along the first direction, and the distance between the multiple horizontal peeling tools and the peeling platform gradually decreases along the direction close to the vertical peeling tool.

[0009] Furthermore, the rotational speed of the multiple horizontal stripping cutters gradually increases along the direction closer to the vertical stripping cutter.

[0010] Furthermore, the vertical peeling assembly includes: a second peeling housing having a second receiving cavity and a second peeling opening facing the peeling platform and communicating with the second receiving cavity; at least a portion of the vertical peeling cutter being rotatably disposed inside the second receiving cavity; and the first peeling housing and the second peeling housing being interconnected; and a hydraulic mechanism having at least a portion disposed inside the receiving cavity and being connected to the vertical peeling cutter.

[0011] Furthermore, both the horizontal and vertical stripping tools are helical tools. The axis of rotation of the horizontal stripping tool extends along the second direction, and the axis of rotation of the vertical stripping tool extends along the third direction. The first, second, and third directions are perpendicular to each other.

[0012] Furthermore, the stripping platform has clamps for gripping the solar laminate to be stripped.

[0013] Furthermore, the solar laminate stripping device also includes multiple speed control components. At least one speed control component is provided on the horizontal stripping component and the vertical stripping component, and the speed control component on the horizontal stripping component is connected to the horizontal stripping cutter, while the speed control component on the vertical stripping component is connected to the vertical stripping cutter.

[0014] Furthermore, the solar laminate stripping device also includes a control component, which is signal-connected to the speed control component.

[0015] Furthermore, the solar laminate stripping device also includes: a suction component, wherein there are multiple suction components, and at least one suction component is respectively provided on the horizontal stripping component and the vertical stripping component, and the first end of the suction component on the horizontal stripping component is connected to the first receiving cavity of the horizontal stripping component, and the first end of the suction component on the vertical stripping component is connected to the second receiving cavity of the vertical stripping component; and a storage component, wherein there are multiple storage components and each corresponds to a suction component, and the storage component is connected to the second end of the corresponding suction component.

[0016] Furthermore, the solar laminate stripping device also includes a drive structure, which is drivenly connected to the stripping structure so that the stripping structure can move relative to the stripping platform.

[0017] Applying the technical solution of this invention, the solar laminate stripping device of this application includes a stripping platform and a stripping structure. The stripping structure is located above the stripping platform, and a stripping space exists between the stripping structure and the stripping platform. The stripping structure includes a horizontal stripping component and a vertical stripping component. The horizontal stripping component has at least one horizontal stripping cutter; the vertical stripping component has at least one vertical stripping cutter. The rotation axis of the horizontal stripping cutter is perpendicular to the rotation axis of the vertical stripping cutter. The distance from the horizontal stripping cutter to the stripping platform is greater than the distance from the vertical stripping cutter to the stripping platform. The horizontal stripping component and the vertical stripping component are interconnected and arranged sequentially along a first direction. When the stripping structure moves relative to the stripping platform along the first direction, the vertical stripping component is located upstream of the horizontal stripping component.

[0018] When using the solar laminate peeling device of this application to peel off solar laminates, since there is a peeling space between the peeling platform and the peeling structure, the solar laminate can be placed in the peeling space and peeled off by the peeling structure. That is, when peeling off the solar laminate, it needs to be placed between the peeling platform and the peeling structure. Since the peeling structure is located above the peeling platform, the side of the solar laminate to be peeled needs to face the peeling structure. Furthermore, when peeling the solar laminate using the peeling structure, the peeling structure moves along a first direction. During this movement, the solar laminate is first peeled off by a horizontal peeling cutter to remove the backsheet and EVA film. Then, the solar cells and solder strips are removed by a vertical peeling cutter. Therefore, the solar laminate stripping device in this application can reduce the labor intensity of operators, improve the stripping effect, avoid injury to operators during the stripping process, and improve the stripping efficiency. Thus, the solar laminate stripping device in this application effectively solves the problems of difficult and inefficient recycling of photovoltaic modules in the prior art.

[0025] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0026] To address the problems of difficult and inefficient recycling of photovoltaic modules in existing technologies, this application provides a solar laminate stripping device.

[0027] like Figure 1 As shown, the solar laminate stripping device of this application includes a stripping platform and a stripping structure. The stripping structure is located above the stripping platform, and there is a stripping space between the stripping structure and the stripping platform. The stripping structure includes a horizontal stripping assembly 10 and a vertical stripping assembly 20. The horizontal stripping assembly 10 has at least one horizontal stripping cutter 11; the vertical stripping assembly 20 has at least one vertical stripping cutter 21. The rotation axis of the horizontal stripping cutter 11 is perpendicular to the rotation axis of the vertical stripping cutter 21. The distance from the horizontal stripping cutter 11 to the stripping platform is greater than the distance from the vertical stripping cutter 21 to the stripping platform. The horizontal stripping assembly 10 and the vertical stripping assembly 20 are interconnected and arranged sequentially along a first direction. When the stripping structure moves relative to the stripping platform along the first direction, the vertical stripping assembly 20 is located upstream of the horizontal stripping assembly 10.

[0028] When using the solar laminate peeling device of this application to peel off solar laminates, since there is a peeling space between the peeling platform and the peeling structure, the solar laminate can be placed in the peeling space and peeled off by the peeling structure. That is, when peeling off the solar laminate, it needs to be placed between the peeling platform and the peeling structure. Since the peeling structure is located above the peeling platform, the side of the solar laminate to be peeled needs to face the peeling structure. Furthermore, when peeling the solar laminate by the peeling structure, the peeling structure moves along a first direction. During this movement, the horizontal peeling cutter 11 first peels off the solar laminate to remove the backsheet and EVA film. Then, the vertical peeling cutter 21 removes the solar cells and solder strips from the solar laminate. Therefore, the solar laminate stripping device in this application can reduce the labor intensity of operators, improve the stripping effect, avoid injury to operators during the stripping process, and improve the stripping efficiency. Thus, the solar laminate stripping device in this application effectively solves the problems of difficult and inefficient recycling of photovoltaic modules in the prior art.

[0029] In one specific embodiment of this application, the horizontal peeling assembly 10 includes a first peeling housing 12, which has a first receiving cavity and a first peeling opening facing the peeling platform and communicating with the first receiving cavity. At least a portion of the horizontal peeling cutter 11 is rotatably disposed inside the first receiving cavity. Furthermore, the vertical peeling assembly 20 includes a second peeling housing 22 and a hydraulic mechanism. The second peeling housing 22 has a second receiving cavity and a second peeling opening facing the peeling platform and communicating with the second receiving cavity. At least a portion of the vertical peeling cutter 21 is rotatably disposed inside the second receiving cavity, and the first peeling housing 12 and the second peeling housing 22 are interconnected. At least a portion of the hydraulic mechanism is disposed inside the receiving cavity and is connected to the vertical peeling cutter 21. In this embodiment, by providing the hydraulic mechanism, the vertical peeling cutter 21 can be moved via the hydraulic mechanism to peel the solar laminate.

[0030] Optionally, there are multiple horizontal peeling cutters 11, which are spaced apart along a first direction, and the distance from the multiple horizontal peeling cutters 11 to the peeling platform gradually decreases along the direction close to the vertical peeling cutter 21. Preferably, the rotational speed of the multiple horizontal peeling cutters 11 gradually increases along the direction close to the vertical peeling cutter 21.

[0031] In one specific embodiment of this application, there are two horizontal peeling blades 11. The horizontal peeling blade 11, located relatively far from the vertical peeling blade 21, can initially perform a rough removal of the backsheet of the solar laminate at a speed of 800 rpm, while the horizontal peeling blade 11, located relatively close to the vertical peeling blade 21, performs a fine removal of the backsheet and EVA film of the solar laminate at a speed of 1500 rpm. Furthermore, when peeling the solar laminate using the vertical peeling blade 21, the rotational speed of the vertical peeling blade 21 is 1500 rpm.

[0032] In one specific embodiment of this application, both the horizontal peeling tool 11 and the vertical peeling tool 21 are helical tools. The axis of rotation of the horizontal peeling tool 11 extends along the second direction, and the axis of rotation of the vertical peeling tool 21 extends along the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0033] Optionally, the stripping platform has clamps for gripping the solar laminate to be stripped.

[0034] Optionally, the solar laminate stripping device further includes multiple speed-regulating components 30. At least one speed-regulating component 30 is respectively provided on the horizontal stripping component 10 and the vertical stripping component 20. The speed-regulating component 30 on the horizontal stripping component 10 is connected to the horizontal stripping cutter 11, and the speed-regulating component 30 on the vertical stripping component 20 is connected to the vertical stripping cutter 21. Furthermore, the solar laminate stripping device also includes a control component, which is signal-connected to the speed-regulating components 30. It should be noted that when the horizontal stripping cutter 11 and the vertical stripping cutter 21 strip the solar laminate at the same location, the rotational speeds of both the horizontal stripping cutter 11 and the vertical stripping cutter 21 will change. After the horizontal stripping cutter 11 and the vertical stripping cutter 21 complete the stripping at the current location, their rotational speeds will reach their maximum. At this point, the stripping structure can be moved to strip other locations of the solar laminate. Furthermore, it should be noted that the horizontal peeling cutter 11 and the vertical peeling cutter 21 peeling the same position of the solar laminate mentioned above do not mean that the horizontal peeling cutter 11 and the vertical peeling cutter 21 peel the same position simultaneously. Rather, the horizontal peeling cutter 11 and the vertical peeling cutter 21 peel at different positions on the solar laminate. The peeling structure does not continue to move at this time, but only continues to move when the horizontal peeling cutter 11 and the vertical peeling cutter 21 reach a preset maximum rotational speed. In other words, in this application, the rotational speed of the speed regulating component 30 can be detected by the control component.

[0035] In one specific embodiment of this application, the solar laminate peeling device further includes a suction component 40 and a storage component. There are multiple suction components 40, with at least one suction component 40 respectively provided on the horizontal peeling component 10 and the vertical peeling component 20. The first end of the suction component 40 on the horizontal peeling component 10 communicates with the first receiving cavity of the horizontal peeling component 10, and the first end of the suction component 40 on the vertical peeling component 20 communicates with the second receiving cavity of the vertical peeling component 20. There are multiple storage components, each corresponding to one of the suction components 40, and the storage component communicates with the second end of the corresponding suction component 40. Since the material peeled off by the horizontal peeling blade 11 remains inside the first peeling housing 12, and the material peeled off by the vertical peeling blade 21 remains inside the second peeling housing 22, the suction components 40 and the storage components can absorb and store the material inside the first peeling housing 12 and the second peeling housing 22.

[0036] Optionally, the solar laminate stripping device further includes a drive structure, which is drivenly connected to the stripping structure to enable the stripping structure to move relative to the stripping platform. In one specific embodiment of this application, the drive structure includes multiple rollers, all of which are drivenly connected to the stripping structure, thereby enabling the stripping structure to move relative to the stripping platform via the multiple rollers. Of course, the drive structure can also be configured in other forms in this application, as long as it ensures that the drive structure can drive the stripping structure to move relative to the stripping platform.

[0037] It should be noted that this application also provides a method for peeling off solar laminates, and this method uses the aforementioned solar laminate peeling device to peel off the solar laminates. The method includes: starting the peeling program of the solar laminate peeling device; calling the peeling step combination parameter group, wherein the parameter group includes the rotation speed of the horizontal peeling cutter, the rotation speed of the vertical peeling cutter, and the relative movement speed between the peeling structure and the peeling platform; peeling the solar laminate along the thickness direction of the solar laminate according to the peeling sequence in the peeling step combination, and automatically peeling according to the peeling step sequence. Furthermore, in this application, a sensor is also provided on the peeling platform. The sensor can detect when the peeling structure moves in the X-axis direction, Y-axis direction, or at an inclined angle between the peeling structure and the peeling platform, and can move according to the maximum rotation speed in the peeling step combination. Moreover, the maximum rotation speed for processing the backsheet layer is greater than or equal to 600 rpm, and the maximum rotation speed for processing the adhesive film layer is greater than or equal to 800 rpm.

[0038] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:
