Description

A photovoltaic cell texturing additive preparation and filling equipment Technical Field

[0001] This utility model belongs to the field of additive filling technology, and in particular relates to a photovoltaic cell texturing additive preparation and filling equipment. Background Technology

[0002] Texturing is one of the key steps in solar cell manufacturing. It can reduce light reflection and improve the photoelectric conversion efficiency of solar cells. Photovoltaic cell texturing additives are chemical auxiliaries added during the texturing process to improve reaction results and product performance. After the texturing additives are produced, they need to be filled into storage containers.

[0003] Currently, the filling nozzles of existing filling equipment are generally exposed to the outside, causing dust and other contaminants to accumulate on their outer walls. During subsequent filling, these contaminants can easily enter the dispensing container along with the additives, reducing the quality of the additives and affecting the final performance of the product.

[0004] To address the aforementioned issues, this application proposes a photovoltaic cell texturing additive preparation and filling device. Summary of the Invention

[0005] The purpose of this invention is to provide a photovoltaic cell texturing additive preparation and filling equipment, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a photovoltaic cell texturing additive preparation and filling device, including a fixed base and a liquid storage tank mounted on the fixed base via a mounting bracket. It also includes two semi-shells symmetrically arranged on both sides of a filling head. The filling head is located below the liquid storage tank. The semi-shells form a cylindrical protective shell to protect the filling head and prevent dust from contacting it. A liquid inlet hopper is fixedly connected to one of the semi-shells. The other semi-shell has an arc-shaped groove that mates with the outer wall of the liquid inlet hopper. A connecting pipe is connected to the bottom of the liquid inlet hopper. A collection box is provided on the top surface of the fixed base, and a connecting hose connects the top of the collection box to the connecting pipe. Additive dripping from the filling head falls into the liquid inlet hopper and is collected in the collection box through the connecting pipe and connecting hose.

[0008] Furthermore, the bottom of the liquid storage tank is provided with a transition pipe one, the top of the filling head is provided with a transition pipe two, and a telescopic pipe connects the transition pipe one and the transition pipe two.

[0009] Furthermore, the first transition tube is provided with fixing plates on both the front and rear sides, the second transition tube is provided with connecting plates on both the front and rear sides at the upper end, and the bottom end of the fixing plate is provided with an electric push rod whose output end is connected to the connecting plate.

[0010] Furthermore, connecting shafts are fixedly provided on the front and rear sides of the lower end of the semi-shell, and a through groove is provided on the connecting plate, with a fixed shaft fixedly provided in the through groove. The connecting shaft and the fixed shaft are rotatably connected to the two ends of the connecting rod, respectively.

[0011] Furthermore, the distance between the connecting rods located on the front and rear sides of the semi-shell is greater than the outer diameter of the semi-shell.

[0012] Furthermore, L-shaped fixing brackets are provided on the left and right sides of the transition tube, and guide rods that are slidably connected to the fixing brackets are provided on the side of the semi-shell.

[0013] Furthermore, a vertical plate is provided below one of the fixing frames, and the vertical plate is slidably connected to the connecting pipe.

[0014] This utility model has the following beneficial effects:

[0015] This utility model uses a semi-shell to form a protective shell that encloses the filling head, preventing external dust from contacting the filling head and also protecting the filling head from damage caused by external forces.

[0016] In this invention, the filling head is enclosed by a protective shell composed of half-shells, and the liquid inlet is located below the filling head. After the additive drips from the filling head into the liquid inlet, it enters the collection box through the connecting pipe and connecting hose, where it is collected uniformly to prevent residual additives from dripping into the outside and causing pollution.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please refer to Figures 1-4. This utility model is a photovoltaic cell texturing additive preparation and filling device, including a fixed base 1 and a liquid storage tank 2 installed on the fixed base 1 via a mounting bracket. It also includes two half-shells 6, symmetrically arranged on both sides of a filling head 5. The filling head 5 is located below the liquid storage tank 2. The half-shells 6 are used to form a cylindrical protective shell to protect the filling head 5 and prevent dust from contacting the filling head 5. A liquid inlet 7 is fixedly connected to one of the half-shells 6. The other half-shell 6 has an arc-shaped groove that matches the outer wall of the liquid inlet 7. The bottom end of the liquid inlet 7 is connected to a connecting pipe 14. The top surface of the fixed base 1 is provided with a collection box 15, and a connecting hose 1501 is connected between the top of the collection box 15 and the connecting pipe 14. The additive dripping from the filling head 5 falls into the liquid inlet 7 and is collected in the collection box 15 through the connecting pipe 14 and the connecting hose 1501.

[0028] This embodiment provides a photovoltaic cell texturing additive preparation and filling device. In the initial state, the two half-shells 6 are combined into a cylindrical protective shell to protect the filling head 5 inside, preventing external dust and other impurities from contacting the filling head 5 and preventing the filling head 5 from being contaminated.

[0029] After the cylindrical protective shell encloses the filling head 5, the liquid inlet 7 is located below the filling head 5 to collect the additive solution that drips after the filling head 5 stops working, preventing the solution from contaminating the working environment.

[0030] The liquid storage tank 2 is provided with a transition tube 201 at the bottom and a transition tube 4 at the top of the filling head 5. A telescopic tube 3 is connected between the transition tube 201 and the transition tube 4. The telescopic tube 3 can extend and retract. By pulling the transition tube 4, the height of the filling head 5 can be adjusted so that the filling head 5 can be used for dispensing containers of different heights.

[0031] The first transition tube 201 is provided with fixed plates 202 on both the front and rear sides, the second transition tube 4 is provided with connecting plates 9 on both the front and rear sides of the upper end, and the bottom end of the fixed plate 202 is provided with an electric push rod 8 whose output end is connected to the connecting plate 9. The electric push rod 8 drives the connecting plate 9 to move vertically, which in turn drives the connecting plate 9 and the second transition tube 4 to move vertically, thereby adjusting the height of the filling head 5.

[0032] The lower end of the semi-shell 6 is fixed with connecting shafts 11 on both the front and rear sides. The connecting plate 9 has a through groove 901, and a fixed shaft is fixed in the through groove 901. The connecting shaft 11 and the fixed shaft are rotatably connected to the two ends of the connecting rod 10. When the connecting plate 9 and the transition tube 4 are moved down by the electric push rod 8, the semi-shell 6 is driven to separate by the transmission action of the connecting rod, so that the cylindrical protective shell composed of the semi-shell 6 is automatically opened.

[0033] The distance between the connecting rods 10 located on the front and rear sides of the semi-shell 6 is greater than the outer diameter of the semi-shell 6, ensuring that the semi-shell 6 will not interfere with the connecting rods 10 when it is separated.

[0034] The transition tube 201 is provided with L-shaped fixing frames 12 on both sides. The half shell 6 is provided with a guide rod 13 that is slidably connected to the fixing frame 12 on its side. The guide rod 13 passes through the fixing frame 12 and is slidably connected to the fixing frame 12. The fixing frame 12 and the guide rod 13 cooperate to guide the movement of the half shell 6.

[0035] One of the fixing frames 12 has a vertical plate 1201 below it. The vertical plate 1201 is slidably connected to the connecting pipe 14. The vertical plate 1201 can support the connecting pipe 14 and improve the stability of the vertical plate 1201.

[0036] It is understood that this utility model can wrap the filling head 5 to prevent external dust and other impurities from coming into contact with the filling head 5, and secondly, it can collect the residual additives dripping from the filling head 5 to prevent pollution of the external environment.

[0037] A specific application of the operation process in this embodiment is as follows: In the initial state, the filling head 5 is located inside the cylindrical protective shell composed of two half-shells 6. During filling, the electric push rod 8 drives the connecting plate 9 and 401 to move downward, so that the height of the filling head 5 is adjusted according to the height of the dispensing container. When the filling head 5 moves downward, the half-shells 6 move away from each other through the transmission action of the connecting rod 10, so that the cylindrical protective shell opens automatically. After filling is completed, the electric push rod 8 drives the connecting plate 9 and 401 to move upward, so that the filling head 5 returns to the initial state. Furthermore, through the transmission action of the connecting rod 10, the half-shells 6 move closer to each other to form a cylindrical protective shell that wraps the filling head 5 inside. At the same time, the liquid inlet 7 is located below the filling head 5. The additives remaining in the filling head 5 will drip into the liquid inlet 7, and then be collected by the collection box 15 through the connecting pipe 14 and the connecting hose 1501, preventing the additives from dripping into the outside and polluting the external environment.
