Description

Technical Field

[0001] This invention relates to the field of photovoltaic recycling technology, and in particular to a separation device and method for cutting and separating photovoltaic modules. Background Technology

[0002] With the increasing global demand for clean energy, solar power has become one of the most popular and widely used renewable energy sources. However, as photovoltaic (PV) modules gradually reach the end of their lifespan or fail, the number of these discarded or faulty modules is constantly increasing, putting pressure on the environment and resources. If they are not recycled and reused, these PV modules will be directly disposed of, resulting in a large amount of waste and environmental pollution.

[0003] Currently, there are several mainstream methods for recycling photovoltaic (PV) modules, including physical and chemical treatment methods. In physical treatment, one common method is crushing, which involves mechanically pulverizing the PV modules. Another method is thermal treatment, which uses high temperatures to decompose the encapsulant and organic materials in the PV modules. However, these methods often only achieve partial material recovery, making complete resource utilization difficult. Among chemical treatment methods, organic solvent dissolution and inorganic acid dissolution are widely used. Organic solvent dissolution uses organic solvents to dissolve the organic materials in the PV modules, thus achieving partial material recovery. Inorganic acid dissolution uses strong acids to dissolve the inorganic materials in the PV modules. However, these methods generate waste liquid during processing, requiring subsequent treatment and increasing the complexity of environmental management. In addition, a common method is the hot-blade method for processing PV panels. This method uses heated blades to cut the PV panels, separating the valuable components. However, this method usually only allows for a single cut and is difficult to completely remove the EVA encapsulant from the PV panels, resulting in high residue levels. Summary of the Invention

[0004] The technical problem to be solved by this invention is that, in order to address the issues that existing photovoltaic modules can only achieve partial material recovery through physical separation methods, making it difficult to achieve complete resource utilization, and that chemical separation methods generate waste liquid during the process, requiring subsequent treatment and increasing the complexity of environmental management, a separation device and method for cutting and separating photovoltaic modules are provided.

[0005] The technical solution adopted by this invention to solve its technical problem is: a separation device for cutting and separating photovoltaic modules, including a worktable and a cutting wire. The cutting wire is arranged on the conveying path of the photovoltaic module. A heating component for heating the cutting wire is arranged on the worktable. The cutting wire is connected end to end to form a closed-loop annular structure. The cutting wire is rotatably mounted on the worktable. A first driving mechanism for driving the cutting wire to rotate is arranged on the worktable, realizing the cutting of the photovoltaic module and the uniform heating of the wire by the heating component. An input mechanism for inputting the photovoltaic module to be separated and an output mechanism for outputting the separated photovoltaic module are arranged on the worktable. The cutting wire is arranged between the input mechanism and the output mechanism. Compared with the prior art, this solution conveys the photovoltaic module to be separated to the cutting wire through the input mechanism, and the first driving mechanism drives the cutting wire to rotate to realize the cutting and separation of the photovoltaic module, reducing the residue of EVA material on the photovoltaic module and improving the cutting efficiency.

[0006] The workbench is fixedly supported by an aluminum profile frame. A heating rod is installed inside the workbench and is located at the input mechanism. The heating rod can preheat the photovoltaic modules.

[0007] To ensure stable and reliable cutting of the cutting wire, in some preferred embodiments, the workbench is provided with a tensioning mechanism for adjusting the tension of the cutting wire;

[0008] The tensioning mechanism includes a first column, a second column, and a screw. A slide rail is provided on the worktable along the direction of the cutting wire. The first and second columns are slidably mounted relative to each other on the slide rail. The screw is rotatably mounted within the slide rail and has two threaded sections with opposite directions of rotation. The first and second columns are threadedly connected to these two threaded sections of the screw. One end of the cutting wire is rotatably mounted on the first column, and the other end is rotatably mounted on the second column. By adjusting the screw to bring the first and second columns closer together or further apart, the tensioning mechanism can adjust the tension of the cutting wire between the first and second columns, ensuring stable and reliable cutting of the photovoltaic module.

[0009] In order to meet the cutting and separation of photovoltaic modules of different thicknesses, in some preferred embodiments, both the first column and the second column are provided with an adjustment mechanism for adjusting the distance between the cutting wire and the worktable.

[0010] The adjustment mechanism includes a lead screw and a nut. Both the first and second columns are equipped with slides that match the nuts. The nuts are slidably disposed within the slides. The lead screw is rotatably mounted within the slides and threadedly connected to the nut. Both ends of the cutting wire are rotatably mounted on the nuts of the first and second columns, respectively. By adjusting the lead screws on the first and second columns, and causing the nuts to slide within the slides of the first or second column, the distance between the cutting wire at one end of the first or second column and the worktable can be adjusted. This allows the equipment to accommodate photovoltaic modules of different thicknesses, improving its versatility.

[0011] To enable the cutting wire to rotate on the worktable, in some preferred embodiments, a roller is rotatably mounted on the nut, and the cutting wire is wound around the roller. By rotatably mounting the roller on the nut and winding the cutting wire around the roller, the cutting wire is made to rotate on the worktable.

[0012] To realize the first driving mechanism, in some preferred embodiments, the first driving mechanism includes a drive motor, a first spline shaft and a spline guide sleeve. The drive motor is fixedly mounted on the worktable. One end of the first spline shaft is connected to the output transmission of the drive motor. The spline guide sleeve is slidably disposed at the other end of the first spline shaft and realizes spline connection between the two. The spline guide sleeve is fixed to a roller on one of the first column and the second column and is coaxially disposed.

[0013] In some preferred embodiments, the input mechanism includes a first guide wheel group and a second guide wheel group. The first guide wheel group consists of a plurality of first guide wheels and is spaced apart on one side of the worktable along the photovoltaic module conveying direction. The second guide wheel group consists of a plurality of second guide wheels and is spaced apart on the other side of the worktable along the photovoltaic module conveying direction. A conveying channel for conveying photovoltaic modules is formed between the first guide wheels and the second guide wheels. A second driving mechanism for driving the first guide wheel group and the second guide wheel group to rotate relative to each other is provided on the worktable.

[0014] In some preferred embodiments, the workbench is provided with a control mechanism for controlling the second guide wheel group to move closer to or further away from the first guide wheel group.

[0015] In some preferred embodiments, the control mechanism includes a control lever, a fixed plate, and a control motor. The second guide wheel assembly is rotatably mounted on the fixed plate. One end of the control lever is rotatably mounted on the fixed plate, and the other end of the control lever is threaded to the worktable. The control motor is fixedly mounted on the worktable, and a second splined shaft is drivenly connected to the output end of the control motor. The first guide wheel assembly is drivenly connected to the second splined shaft through a bevel gear assembly. A large bevel gear is coaxially mounted on the second guide wheel of the second guide wheel assembly. A small bevel gear is rotatably mounted on the fixed plate. The large bevel gear and the small bevel gear mesh with each other, and the small bevel gear is slidably mounted on the second splined shaft to achieve a splined connection between the two.

[0016] In some preferred embodiments, the output mechanism includes a conveyor belt rotatably mounted on a workbench, and the workbench is provided with a third drive mechanism for driving the conveyor belt to rotate.

[0017] A method for using a separation device for cutting and separating photovoltaic modules as described above includes the following steps:

[0018] S1. Based on the width of the photovoltaic module to be separated, adjust the distance between the first guide wheel group and the second guide wheel group to the required distance using the control lever;

[0019] S2. Based on the height of the photovoltaic module to be separated, adjust the distance between the cutting wire and the worktable to the required distance using the adjustment mechanism;

[0020] S3. Control the tensioning mechanism and adjust the cutting wire to the required tension.

[0021] S4. Start the first drive mechanism, the second drive mechanism, the third drive mechanism and the heating component. The heating component heats the cutting steel wire rope to the required temperature. Place the photovoltaic module to be separated on the conveying channel of the workbench. The photovoltaic module to be separated is conveyed to the cutting steel wire through the first guide wheel group and the second guide wheel group. The cutting steel wire rotates and cuts and separates the photovoltaic module that is conveyed.

[0022] S5, the output mechanism outputs the photovoltaic modules after separation.

[0023] The beneficial effects of the present invention are as follows: When the separation device and method for cutting and separating photovoltaic modules of the present invention are used, the photovoltaic modules to be separated are conveyed to the cutting wire through the input mechanism, and the first driving mechanism drives the cutting wire to rotate to achieve the cutting and separation of the photovoltaic modules. This reduces the residue of EVA material on the photovoltaic modules, improves the cutting efficiency, and avoids the problems of existing photovoltaic modules using physical separation methods, which can only achieve partial material recovery and are difficult to achieve complete resource utilization, as well as the problems of chemical separation methods generating waste liquid during the process, which require subsequent treatment and increase the complexity of environmental management.
