[0016] Figure 1 The figure is a schematic diagram of the three-dimensional structure of a recycling pretreatment device for photovoltaic modules according to an embodiment of the present invention.

[0017] Reference Figure 1According to an embodiment of the present invention, a recycling pretreatment device for photovoltaic modules includes a workbench 1 and a transport mechanism 2. The surface of the workbench 1 is flat, and transport mechanisms 2 for transporting waste photovoltaic modules are respectively provided on both sides of the edge. In addition, according to an embodiment of the present invention, a recycling pretreatment device for photovoltaic modules also includes: a lifting platform 3, multiple groups of disassembly components 4, a truss 5 and a mechanical arm 6. A feed port 11 matching the lifting platform 3 is provided in the workbench 1, and the lifting platform 3 can be lifted and lowered between the workbench 1 table and the transport mechanism 2, so as to complete the loading and unloading actions. Each group of disassembly components 4 can be movably arranged on the surface of the workbench 1, and each group of disassembly components 4 is distributed along the periphery of the feed port 11. The truss 5 is erected above the lifting platform 3, the truss 5 spans the feed port 11, and the extension direction of the truss 5 is the same as the width direction of the feed port 11. The mechanical arm 6 includes a first part 61 and a second part 62 connected by hinges, wherein the first part 61 is movably arranged on the surface of the truss 5, and the second part 62 is connected to the clamping claw 7. When the truss 5 moves, the clamping claws 7 grab the junction box on the surface of the photovoltaic module and remove the junction box during the movement of the truss 5.

[0018] Figure 2 The figure is a schematic cross-sectional structure diagram of a recycling pretreatment device for photovoltaic modules according to an embodiment of the present invention.

[0019] Reference Figure 2 Specifically, each group of disassembly components 4 includes: a fixed seat 41, a cylinder assembly 42 and a baffle 43. Among them, the fixed seat 41 is fixedly arranged on the surface of the workbench 1, and each fixed seat 41 is located at the periphery of the feed port 11. The fixed end (cylinder part) of the cylinder assembly 42 is fixedly connected to the fixed seat 41, and the movable end (piston part) of the cylinder assembly 42 is fixedly connected to the baffle 43. The moving direction of the movable end of the cylinder assembly 42 is opposite to the extension direction of the baffle 43, and the end of the baffle 43 is raised, so as to match the lifting platform 3. When the transport mechanism 2 is running, the waste photovoltaic components are transported by the transport mechanism 2 on one side of the lifting platform 3, and the other side of the lifting platform 3 is used to transport the photovoltaic components that have been disassembled. During the disassembly process of the photovoltaic components such as the frame and the junction box, the first part 61 and the second part 62 rotate, so that the robot arm 6 can expand and disassemble photovoltaic junction boxes of different specifications.

[0020] Furthermore, an electric slider 51 is provided on the truss 5. One end of the first part 61 is rotatably connected to the electric slider 51 through a universal joint 8, and the other end of the first part 61 is hinged to the second part 62. The disassembly range of the robot arm 6 is further increased by the rotation of the universal joint 8 on the horizontal plane and the vertical plane. Preferably, in this embodiment, a recognition module 9 for identifying the junction box is also provided at the connection between the second part 62 and the clamping claw 7, so as to facilitate the robot arm 6 to quickly locate the position of different junction boxes for disassembly. In this embodiment, the recognition module 9 is a machine vision acquisition module such as a CCD (a camera using a charge coupled device as an image sensor) camera or a CMOS (a camera using a complementary metal oxide semiconductor image sensor) camera. After the recognition module 9 confirms the position of the junction box, the main control device starts the electric slider 51 or the universal joint 8 to adjust the position of the robot arm 6.

[0021] Specifically, the interior of the workbench 1 is also provided with a storage box 12 for recycling the frames of photovoltaic modules. The storage box 12 is placed inside the workbench 1. In other embodiments, a pull-out sliding structure is formed between the storage box 12 and the inner cavity wall of the workbench 1. In this embodiment, the storage box 12 does not contact the inner cavity wall of the workbench 1, but is only placed at a position opposite to the lifting platform 3, and the transportation mechanism 2 is located between the fixed frame and the storage box 12, so that after the photovoltaic module frame is disassembled, the frame quickly falls into the storage box 12. Furthermore, in this embodiment, the transportation mechanism 2 is a transmission device such as a conveyor belt or roller. When the lifting platform 3 is at the maximum height, the surface of the lifting platform 3 is coplanar with the surface of the workbench 1; when the lifting platform 3 is at the lowest height, the surface of the lifting platform 3 is coplanar with the surface of each transportation mechanism 2.

[0022] When the transport mechanism 2 transports the waste photovoltaic modules to the lifting platform 3, the lifting platform 3 drives the photovoltaic modules to rise to the surface of the workbench 1 to complete the loading action. The disassembly component 4 removes the frame of the photovoltaic module, and the robot arm 6 removes the cables and junction boxes of the photovoltaic module, thereby completing the disassembly action. After the disassembly is completed, the lifting platform 3 descends to the lowest point, and another transport mechanism 2 drives the photovoltaic modules on the lifting platform 3 to move, thereby completing the unloading action, and the remaining frame of the disassembly falls into the storage box 12.

[0023] In summary, the present invention drives the photovoltaic components to complete the loading and unloading actions through the transfer function of the lifting platform, and the joint action of each group of disassembly components and the robotic arm enables the frames, junction boxes and other structures of the photovoltaic components to be quickly disassembled for further recycling.
