Description

Technical Field

[0001] The present invention belongs to the technical field of recycling equipment, and in particular relates to a retired photovoltaic module recycling device. Background Art

[0002] In order to save resources, reduce resource waste and environmental pollution, in the photovoltaic field, photovoltaic modules that have reached the end of their service life or are partially damaged by faults are often recycled for their normal recyclable parts. Among them, the solar cell board, as an important energy-collecting component of the photovoltaic panel, is an important part of the recycling of photovoltaic modules.

[0003] At present, most solar cell panels are sandwiched and bonded with two layers of EVA to form protection. During the recycling process, these two layers of EVA need to be removed. Because their size and thickness specifications are uniform, the common removal method mostly uses a hot cutter to hot-melt dismantle the bonding parts. However, the general hot-melt dismantling method currently mostly directly uses a machine to push the hot cutter or the photovoltaic panel to produce relative movement for dismantling. The former requires the photovoltaic panel to be clamped before dismantling. The dismantling process is cumbersome and easily causes extrusion damage to the clamped part of the solar cell. The latter easily causes the EVA layer or solar cell layer after cutting to have no suitable fixed structure and produce movement or warping, thereby affecting the operation of the machine or causing subsequent collection difficulties, which does not meet the needs of efficient and convenient recycling.

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Example 1: Figure 1-4 As shown, a retired photovoltaic module recycling device includes a base 1 and a control panel. The base 1 is an overall U-shaped structure with an opening facing upward, and a disassembly mechanism is provided in the opening of the base 1;

[0024] The disassembling mechanism includes a rack 11, a hot cutter 12 and a pushing mechanism. The rack 11 is arranged at the front end of the base 1. There are two hot cutters 12 and they are spaced apart from each other. The hot cutter 12 is arranged at one end of the rack 11 close to the base 1. The pushing mechanism is arranged on the rack 11.

[0025] The pushing mechanism includes a push plate 2, an electric control rail and a clamp. A mounting groove 21 is opened in the middle of the lower end of the rack 11. The electric control rail is arranged in the mounting groove 21. The push plate 2 is transmission-connected with the electric control rail. The clamp is arranged on the rack 11 and corresponds to the hot cutter 12.

[0026] When recycling and splitting the photovoltaic panel, the photovoltaic panel is placed on the storage rack 11. After it is centered and placed stably, the electric control rail is turned on through the control panel to drive the push plate 2. The push plate 2 is used to push the photovoltaic panel, which will make the photovoltaic panel actively approach the hot cutting knife 12 to split the panel layers, so that the EVA layer that clamps the battery cell is hot-melted and disassembled, so that the battery cell layer can be recovered. In the process of pushing the photovoltaic panel, the clamp will clamp and fix the front end of the photovoltaic panel, which can avoid the EVA layer from warping, shaking after separation, or sliding after complete disassembly during the disassembly of the photovoltaic panel, thereby affecting the equipment or polluting the recycling site, which is more conducive to recycling and splitting.

[0027] The clamp includes a synchronization rod 3, a rectangular frame 4, a fixed plate 41, a movable clamp and a guide plate 42. The rectangular frame 4 is slidably connected along the length direction of the base 1. There are two fixed plates 41 and they are arranged in the rectangular frame 4. The two fixed plates 41 correspond to two hot cutting knives 12 respectively. There are two movable clamps and they are respectively arranged at the upper and lower ends of the rectangular frame 4. There are several guide plates 42 and they are arranged on the upper and lower sides of the opening of the base 1 through a bracket. The guide plate 42 corresponds to the position of the movable clamp. The synchronization rod 3 is arranged on the side of the rectangular frame 4 and corresponds to the position of the push plate 2.

[0028] The movable clamp includes a clamping plate 5 and a plurality of elastic pins. The clamping plate 5 is located in the rectangular frame 4 and corresponds to the fixed plate 41. The elastic pin includes a sliding rod 51, a limiting plate 52 and a spring 53. The sliding rod 51 is slidably connected to the rectangular frame 4 and one end is connected to the clamping plate 5. The other end of the sliding rod 51 is connected to the limiting plate 52. The spring 53 is sleeved on the sliding rod 51 and located outside the opening of the rectangular frame 4. The limiting plate 52 corresponds to the guide plate 42. The guide plate 42 has an isosceles trapezoidal structure as a whole and its two oblique sides correspond to the front and rear ends of the base 1.

[0029] The upper and lower ends of the opening of the rectangular frame 4 are both provided with engaging grooves matching with the clamping plate 5 .

[0030] When the front end of the photovoltaic panel is initially split by hot melting, the battery layer will extend between the two fixed plates 41 as it is split and pushed, and the two EVA layers are respectively located at the ends of the two fixed plates 41, thereby achieving layered splitting. As the push plate 2 continues to push the photovoltaic panel, the synchronization rod 3 is pushed by the push plate 2 to move forward synchronously with the photovoltaic panel, that is, the entire clamp moves corresponding to the front end of the photovoltaic panel until the limit piece 52 in the movable clamp abuts against the hypotenuse of the guide plate 42 in the isosceles trapezoid. In this way, under the obstruction of the guide plate 42, the slide rod 51 can only be The clamp 5 is pushed to cooperate with the fixing plate 41 to clamp and pull the EVA layer. On the one hand, the clamp fixes the EVA layer and the two fixing plates 41 limit the battery layer, which can play a role in the stable restriction of different layers, ensuring that the position of the layers is relatively fixed during the disassembly process. On the other hand, the clamp pushes the plate 2 to move synchronously, and in the process of clamping the photovoltaic panel, it can play a certain auxiliary traction effect. Compared with the method of simply pushing the photovoltaic panel to abut against the hot cutter 12 for separation, it is more stable and has higher hot melting efficiency.

[0031] Finally, after the disassembly is completed, the slide rod 51 as a whole corresponds to the lowest point of the hypotenuse on the other side of the guide plate 42, that is, it is disengaged and reset by the spring 53, so that the staff on the other side can quickly take out the corresponding hierarchical components from different positions in the rectangular frame 4 to complete classification and rapid recycling.

[0032] The hot cutting knife 12 is laterally and evenly provided with a plurality of guide bars 6 at one end relative to the storage rack 11, and the plurality of guide bars 6 are slidably connected with the fixed plate 41; on the one hand, the arrangement of the guide bars 6 can further serve to receive the photovoltaic panel components and improve stability; on the other hand, the guide bars 6 inserted in the fixed plate 41 and relatively fixed in position can separate the different layers after hot-melt disassembly, thereby avoiding adhesion between the EVA layer and the battery cell layer during the subsequent disassembly process, thereby further improving the convenience of subsequent recycling.

[0033] The base 1 is also provided with two hot cutters 12 and a load-bearing plate corresponding to the lower side of the rectangular frame 4 at one end relative to the storage rack 11; this makes it easier for subsequent staff to pull and use force when taking out the layers, thereby improving convenience.

[0034] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
