Recycling them is a beneficial and environmentally friendly energy-saving undertaking for the country and its people. However, there is currently no complete recycling process technology in China to complete the recycling of photovoltaic panels. This technology integrates current domestic production methods and innovates a complete production process, achieving the goal of mechanically replacing automated production to complete material feeding, wire box cutting, frame disassembly, glass separation, and physical metal recycling. Utility Model Content

[0003] The purpose of this invention is to provide a production line for recycling decommissioned photovoltaic panels to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a retired photovoltaic panel recycling production line, comprising: a pallet conveyor, a photovoltaic panel lifting device above the pallet conveyor, the photovoltaic panel lifting device connecting to a wire cutting box machine via a positioning conveyor line, the wire cutting box machine connecting to a frame removal machine via a positioning conveyor line, the frame removal machine connecting to a preheating machine via a positioning conveyor line, the preheating machine connecting to a hot cutting machine, the hot cutting machine connecting to a material unloading conveyor line, and a palletizing robot on one side of the material unloading conveyor line.

[0005] Preferably, the photovoltaic panel hoist is connected to the junction box machine via a first photovoltaic panel conveyor.

[0006] Preferably, the wire box cutting machine is connected to the frame removal machine via a second photovoltaic panel conveyor.

[0007] Preferably, the frame-removing machine is connected to the preheating machine via a third photovoltaic panel conveyor.

[0008] Preferably, the third photovoltaic panel conveyor, the second photovoltaic panel conveyor, and the first photovoltaic panel conveyor are all equipped with a positioning and alignment mechanism.

[0009] A process for recycling decommissioned photovoltaic panels includes the following steps:

[0010] S. The stacked photovoltaic panels are fed to the pallet conveyor, which then delivers the stacked photovoltaic panels to the area below the photovoltaic panel hangers;

[0011] S. The photovoltaic panel hoisting device operates, lifting a solar photovoltaic panel and sending it to the first photovoltaic panel conveyor;

[0012] S. The first photovoltaic panel conveyor is in operation, positioning and conveying the photovoltaic panels. During the conveying process, the rollers are driven by the cylinder to move, and the photovoltaic panels move forward in the set position and are delivered to the wire cutting box machine.

[0013] S. When the junction box cutting machine is working, the photovoltaic panel is sent to the pneumatic stopper and stops. After the junction box is removed by the junction box cutting machine, the stopper falls, and the conveyor built into the junction box cutting machine starts working, and the photovoltaic panel enters the second photovoltaic panel conveyor.

[0014] S. The second photovoltaic panel conveyor sends the solar photovoltaic panels with the junction boxes removed to the frame removal machine, and repositions them during the conveying process to keep the photovoltaic panels in the set position as they move forward.

[0015] S. When the frame removal machine detects the photovoltaic panel, the cylinder drives the stopper to stop the photovoltaic panel in the designated position. The pneumatic frame adjustment device works to adjust the position of the photovoltaic panel. At the same time, the left and right gripper devices move to the designated position to clamp the frame. The grippers move in the opposite direction to remove the left and right frames. Another pneumatic actuator pushes the frame down to the conveyor and send it to the aluminum alloy storage box. At the same time, the middle rotating device works to drive the photovoltaic panel to rotate 90° for positioning. The left and right grippers move twice to remove the front and rear frames. The photovoltaic panel with the frames removed is conveyed to the third photovoltaic panel conveyor.

[0016] S. The third photovoltaic panel conveyor operates, allowing the photovoltaic panels with their frames removed to move forward to the preheater for preheating, then into the hot cutting machine for cutting, and finally transported by the fourth photovoltaic panel conveyor to the palletizing robot for palletizing.
