Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic texturing, and more specifically, to a texturing device for photovoltaic solar panels. Background Art

[0002] The main principle of photovoltaic cell texturing is to form a layer of fine texture structure on the surface of the cell, thereby increasing the scattering and absorption of light and improving the photoelectric conversion efficiency. Texturing can make light reflect multiple times on the surface of the cell, increase the interaction between light and the cell, and thus enhance the cell's ability to absorb light. Chemical immersion texturing is often used in the process of photovoltaic panel texturing. Chemical immersion texturing is a simple and easy texturing method. The photovoltaic cell is immersed in the texturing solution, and the texturing solution corrodes the surface of the photovoltaic panel, gradually forming a velvet layer.

[0003] The chemical dipping texturing method is low-cost and suitable for large-scale production, but the chemical dipping texturing method has the problem of unstable texturing quality, which requires fine operation adjustment and appropriate process parameter control. Based on this, the utility model designs a texturing equipment for photovoltaic solar panels to solve the above problem. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a texturing device for photovoltaic solar panels to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a texturing device for photovoltaic solar panels, comprising a texturing pool, an atomizing chamber fixedly mounted at the bottom of the texturing pool, an enamel heating rod disposed at the bottom of the atomizing chamber, a solution chamber and an atomizing chamber disposed inside the texturing pool, an aeration device disposed at the bottom of the solution chamber, and a material inlet disposed at the top of the texturing pool corresponding to the position of the solution chamber;

[0006] A top frame is slidably fitted on the top of the texturing pool, a group of electric push rods are fixedly mounted on the lower surface of the top frame, and a bottom frame for placing photovoltaic panels is fixed on the output end of the electric push rods;

[0007] A plurality of diversion pipes are fixedly installed at the bottom of the mist erosion chamber, and a plurality of nozzles are fixedly installed on the diversion pipes. One end of the diversion pipe passes through the texturing pool and is connected with the top of the atomization chamber. An air guide pipe is fixedly connected to the top of one side of the atomization chamber, and the top end of the air guide pipe passes through the top of the texturing pool and is fixedly installed with an air collecting hood.

[0008] As a preferred technical solution of the present invention, a drainage pipe is provided at the bottom of the texturing pool, and one end of the drainage pipe is connected to the bottom of the mist erosion chamber.

[0009] As a preferred technical solution of the present invention, an exhaust fan is fixedly installed on the air guide pipe, and the air collecting hood is located directly above the mist erosion chamber.

[0010] As a preferred technical solution of the present invention, the top of one side of the atomization chamber is fixedly connected to a mist pipe, a blower is fixedly installed on the mist pipe, and several of the diversion pipes are fixedly connected to one end of the mist pipe.

[0011] As a preferred technical solution of the present invention, the solution chamber and the mist erosion chamber are separated by a partition, a closing plate is provided on the feed port, and electromagnetic valves are installed on the drain pipe, air guide pipe and mist pipe.

[0012] As an optimal technical solution of the present invention, two threaded screws are rotatably connected to the top of the texturing pool, one end of the two threaded screws passes through the texturing pool and is fixed with a sprocket, chains are sleeved on the outside of the two sprockets, and a servo motor is fixedly installed on one side of the texturing pool through a bracket, and the output end of the servo motor is fixedly connected to a sprocket.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model places the photovoltaic panel inside the solution chamber through the cooperation of the electric push rod and the bottom frame. The texturing liquid in the solution chamber pre-corrodes the photovoltaic panel so that textures appear on the surface of the photovoltaic panel in advance. The purpose of this step is to facilitate subsequent atomization corrosion. The top frame drives the pre-corroded photovoltaic panel into the atomization chamber. The enamel heating rod can completely convert a certain amount of texturing liquid inside the atomization chamber into corrosion mist. Under the joint action of the blower and the exhaust fan, the corrosion mist will circulate directionally in the texturing pool and the atomization chamber. The corrosion mist rises from the bottom of the atomization chamber and is evenly blown to the lower surface of the photovoltaic panel. The continuous flow of corrosion mist ensures that the corrosion mist can evenly corrode the lower surface of the photovoltaic panel in each texturing stage, thereby ensuring the texturing quality of the photovoltaic panel. The texturing device is simpler to operate and can complete the texturing operation of the photovoltaic panel without fine adjustment and parameter control. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 3 As shown, the utility model provides a texturing device for photovoltaic solar panels, comprising a texturing pool 1, an atomizing chamber 3 fixedly mounted at the bottom of the texturing pool 1, an enamel heating rod 16 provided at the bottom of the atomizing chamber 3, a solution chamber 4 and an atomizing chamber 5 provided inside the texturing pool 1, an aeration device 10 provided at the bottom of the solution chamber 4, and a feed port 2 provided at the top of the texturing pool 1 corresponding to the position of the solution chamber 4;

[0021] A top frame 13 is slidably fitted on the top of the texturing pool 1. A set of electric push rods 14 are fixedly mounted on the lower surface of the top frame 13. A bottom frame 15 for placing photovoltaic panels is fixed at the output end of the electric push rods 14.

[0022] A plurality of diversion pipes 11 are fixedly installed at the bottom of the mist erosion chamber 5, and a plurality of nozzles 12 are fixedly installed on the diversion pipes 11. One end of the diversion pipe 11 passes through the texturing pool 1 and is connected to the top of the atomization chamber 3. An air guide pipe 7 is fixedly connected to the top of one side of the atomization chamber 3. The top end of the air guide pipe 7 passes through the top of the texturing pool 1 and is fixedly installed with an air collecting hood 8.

[0023] An exhaust fan 9 is fixedly installed on the air duct 7. The exhaust fan 9 can enable the air duct 7 to suck out the mist in the texturing pool 1. The air collecting hood 8 is located just above the mist erosion chamber 5. The setting of the air collecting hood 8 improves the collection efficiency of the air duct 7 for the mist.

[0024] A mist pipe 17 is fixedly connected to the top of one side of the atomizing chamber 3. A blower 18 is fixedly installed on the mist pipe 17. The blower 18 can continuously extract the mist in the atomizing chamber 3 and send it into the mist erosion chamber 5. Several diversion pipes 11 are fixedly connected to one end of the mist pipe 17.

[0025] During the texturing process of the texturing equipment for photovoltaic solar panels, the closing plate 23 is opened, and the photovoltaic panel is placed on the bottom frame 15. A texturing liquid is provided inside the solution chamber 4. The aeration device 10 blows gas into the solution chamber 4 to stir the solution in the solution chamber 4 so that the concentration of the texturing liquid is uniform. The electric push rod 14 drives the bottom frame 15 to rise and fall, so that the photovoltaic panel can freely enter and exit the solution chamber 4 or the erosion chamber 5. The top frame 13 can drive the bottom frame 15 to move horizontally, and the photovoltaic panel can be moved horizontally to the top of the erosion chamber 5 or the solution chamber 4.

[0026] When the photovoltaic panel placed on the bottom frame 15 enters the solution chamber 4, the texturing liquid will corrode the silicon wafer on the lower surface of the photovoltaic panel, causing lines to appear on the surface of the silicon wafer. The appearance of these lines helps the subsequent etching smoke to corrode the silicon wafer again, thereby accelerating the efficiency of the subsequent smoke etching. During the pre-etching process, the closing plate 23 needs to be removed to ensure normal aeration of the aeration device 10.

[0027] After the pre-corrosion of the photovoltaic panel along with the bottom frame 15 into the mist erosion chamber 5, the feed port 2 is tightly closed by the closing plate 23, a certain amount of texturing liquid is injected into the mist chamber 3, and the filling port of the mist chamber 3 is closed, the enamel heating rod 16 is started, and the texturing liquid in the mist chamber 3 is converted into corrosive mist, the blower 18 and the exhaust fan 9 are started at the same time, under the joint action of the blower 18 and the exhaust fan 9, the corrosive mist will circulate in a direction inside the texturing pool 1 and the mist chamber 3, and the corrosive mist will be discharged from the mist chamber 3. The bottom of the erosion chamber 5 rises and blows evenly toward the lower surface of the photovoltaic panel. The continuously flowing corrosive mist ensures that the corrosive mist can evenly corrode the lower surface of the photovoltaic panel in each texturing stage, thereby ensuring the texturing quality of the photovoltaic panel. The arrangement of several diversion pipes 11, nozzles 12 and gas collecting hoods 8 enables the corrosive mist to diffuse evenly and rise steadily in the erosion chamber 5. When the preset corrosion time is reached, the enamel heating rod 16, blower 18 and exhaust fan 9 are turned off, the closing plate 23 is opened, and the photovoltaic panel can be taken out.

[0028] In order to allow the liquid accumulated at the bottom of the mist erosion chamber 5 to be discharged smoothly, a drain pipe 6 is provided at the bottom of the texturing pool 1. One end of the drain pipe 6 is connected to the bottom of the mist erosion chamber 5. The liquid accumulated at the bottom of the mist erosion chamber 5 can be discharged through the drain pipe 6.

[0029] Among them, the solution chamber 4 and the mist erosion chamber 5 are separated by a partition, a closing plate 23 is provided on the feed port 2, and solenoid valves are installed on the drain pipe 6, the air duct 7 and the mist pipe 17, which can control the opening and closing of the drain pipe 6, the air duct 7 and the mist pipe 17.

[0030] In order to control the horizontal movement of the top frame 13 on the top of the texturing tank 1, two threaded screws 19 are rotatably connected to the top of the texturing tank 1. One end of each threaded screw 19 passes through the texturing tank 1 and is fixed to a sprocket 20. A chain 21 is sleeved on the outside of the two sprockets 20. A servo motor 22 is fixedly installed on one side of the texturing tank 1 through a bracket. The output end of the servo motor 22 is fixedly connected to a sprocket 20. By starting the servo motor 22, the sprocket 20 can be controlled to rotate. Through the transmission of the chain 21, the two threaded screws 19 will rotate synchronously, thereby driving the top frame 13 to move back and forth horizontally.
