Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic silicon material conveying, in particular to a photovoltaic silicon material chain plate conveying device. Background Art
[0002] In the production process of solar photovoltaic panels, photovoltaic silicon materials need to be processed. In the process, hydrofluoric acid is used to pickle the surface of the photovoltaic silicon material, and then water is used to remove the hydrofluoric acid on the surface of the silicon material. The treated silicon material has the surface oxide layer washed away, thereby ensuring the quality of the product in the subsequent production process of solar photovoltaic panels.
[0003] The pickling and water washing of photovoltaic silicon materials are located in different areas. After the photovoltaic silicon materials are pickled in the pickling area, they need to be transferred to the water washing area for water washing. The existing transfer method adopts the method of cooperating with a truss and a manipulator, that is, the pickling truss manipulator and the water washing truss manipulator share a set of walking tracks, which means that the pickling truss manipulator and the water washing truss manipulator can run to the same position in the middle of the walking track to perform material shifting and transfer work.
[0004] In this case, the pickling truss robot and the water-washing truss robot require very rigorous electrical program control and multi-level safety protection measures to ensure that the two robots do not collide in space, and the program logic is relatively complex; at the same time, the operating area of the pickling truss robot and the operating area of the water-washing truss robot cannot be completely physically isolated, and the acid gas evaporated in the equipment will diffuse and flow throughout the equipment, affecting the effect of the material after pure water cleaning in the later stage; therefore, a photovoltaic silicon material conveying and transfer device that can effectively prevent hydrofluoric acid gas from spreading in large quantities in the equipment, thereby ensuring the cleaning effect of photovoltaic silicon materials, is an existing problem that needs to be solved.

A conveying mechanism is arranged in the trough body, and the conveying mechanism is arranged from the feed end to the discharge end.

An isolation plate is arranged on the fixed plate, and the isolation plate isolates the space above the feed end and the discharge end from each other.
[0008] Furthermore, the partition also includes a movable plate, which is hinged to the fixed plate, and the movable plate can cover the discharge end.
[0009] Furthermore, there are multiple spray pipes, and the spray heads are arranged obliquely downward; a drainage outlet is provided at the bottom of the trough body.
[0010] Furthermore, the conveying mechanism includes a frame, a driving motor is arranged at one end of the frame, the driving motor is connected to the driving shaft, a driven shaft is arranged at the other end of the frame, sprockets are arranged on the driving shaft and the driven shaft, and chain plates are installed through the sprockets.

[0012] Furthermore, a motor box is arranged outside the driving motor.
[0013] Furthermore, a transfer box is placed on the chain plate, and the photovoltaic silicon material is placed in the transfer box.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0023] like Figure 1-4 As shown, in the conveying device of this embodiment, a trough body 1 is provided, a spray pipe 11 is provided above the trough body 1 , a spray head 111 is arranged and installed on the spray pipe 11 , and a drain port 12 is provided at the bottom of the trough body 1 .
[0024] A partition 2 is arranged on the trough body 1, and the partition 2 includes a fixed plate 21, a movable plate 22 and an isolation plate 23. The fixed plate 21 is fixedly connected to the trough body 1, and the fixed plate 21 divides the upper part of the trough body 1 into two parts, a feed end 4 and a discharge end 3. An isolation plate 23 is arranged on the fixed plate 21, and the isolation plate 23 isolates the upper space of the feed end 4 and the discharge end 3 from each other; the movable plate 22 is hinged to the fixed plate 21, and the movable plate 22 can cover the discharge end 3.
[0025] A conveying mechanism 5 is arranged in the trough body 1, and a frame 51 is arranged in the conveying mechanism 5. The frame 51 is arranged from the feed end 4 to the discharge end 3. A driving motor 56 is arranged at one end of the frame 51, which is connected to a driving shaft 57 through the driving motor 56. A sprocket 54 is arranged on the driving shaft 57. A driven shaft 53 is arranged at the other end of the frame 51, and a sprocket 54 is installed on the driven shaft 53. There are two sprockets 54 on the driving shaft 57 and the driven shaft 53 respectively, and the sprockets 54 on the driving shaft 57 and the driven shaft 53 correspond to each other. Chain plates 55 are installed through the driving shaft 57 and the sprockets 54 on the driven shaft 53. There are two chain plates 55 and they are arranged on both sides of the frame 51 respectively. A transfer box 6 is placed through the chain plate 55, and the photovoltaic silicon material is placed in the transfer box 6. A motor box 52 is arranged outside the driving motor 56.
[0026] The principle of this utility model is:
[0027] When the utility model is in use, after the photovoltaic silicon material is pickled, the pickled photovoltaic silicon material is placed on the chain plate 55 in the conveying mechanism 5 by the pickling truss manipulator, and then the driving motor 56 is started to convey the photovoltaic silicon material to the discharge end 3, and then the movable plate 22 on the partition 2 is opened, and the material is taken out at the discharge end 3 by the water washing truss manipulator, and then the movable plate 22 is closed, and then the material is washed with water; the setting of the movable plate 22 enables the discharge end to be covered when the material is not being transported, thereby effectively preventing the acid gas in the pickling area and the tank body 1 from diffusing into the tank body in the water washing area through the discharge end, which helps to ensure the effect of subsequent water washing.
[0028] During the process of transporting the photovoltaic silicon material from the feed end 4 to the discharge end 3, the photovoltaic silicon material is flushed through the spray pipe 11 (multiple spray pipes 11 can be provided). Therefore, on the one hand, the diffusion of hydrofluoric acid gas in the tank body 1 can be effectively avoided, and on the other hand, the hydrofluoric acid contaminated on the surface of the photovoltaic silicon material can be flushed, thereby effectively avoiding a large amount of hydrofluoric acid vapor from the pickling section to the water washing section, thereby effectively ensuring the effect of water washing, and the flushing water can be discharged from the drain port 12 at the bottom of the tank body 1 for treatment.
[0029] In the present invention, sprocket 54 and chain plate 55 are involved. Sprocket 54 and chain plate 55 are common structures of existing chain plate conveyors and are not described in detail. At the same time, since hydrofluoric acid is used in the pickling of photovoltaic silicon materials, and hydrofluoric acid is highly corrosive, the material of the entire equipment needs to be hydrofluoric acid-resistant material, such as the commonly used monel400 alloy, which can ensure the long-term stable operation of the equipment.
