Description
Technical Field
The utility model relates to an even sculpture water film spray set of going out water belongs to solar photovoltaic cell and makes technical field.
Background
In the field of solar cell licenses, a water film has been widely used in wet etching as a way to protect against corrosion during the post-diffusion P-N junction etching process. The quality of the water film also affects the appearance of the etched silicon wafer, the electrical property of the cell and the like. The water film is too thin, which causes incomplete covering of the silicon chip, over-etching, edge whitening, edge blackening under EL detection and the like, and seriously affects the appearance and the electrical property. The water film is too thick and can fall water in the etching groove, dilutes etching groove acidizing fluid concentration, and then influences edge etching effect and increases the liquid medicine consumption, causes the etching effect insufficient, and chemical cost increases.
At present, in 5-pass, especially 8-pass etching machines, the water spraying pressure of each pass of water film is unstable, so that the difference between passes is easily caused, and the formed water film is too thin or too thick. Therefore, how to reduce the water spraying difference of the water films among the passes and ensure the quality of the water films becomes a difficult problem to be solved urgently.
Disclosure of Invention
The utility model aims to solve the technical problem that an even sculpture water film spray set of going out water is provided.
In order to solve the technical problem, the utility model discloses a technical scheme does:
the utility model provides an even sculpture water film spray set of play water, includes cylindrical water storage tank, level gauge, flowmeter, a plurality of water pipe and a plurality of nozzle, the water pipe is on a parallel with water storage tank length direction sets up, connects gradually rather than the bottom, the water pipe bottom is equipped with a plurality ofly along length direction in proper order the nozzle, the level gauge sets up in the water storage tank, the flowmeter sets up the water storage tank water inlet, water storage tank one end inboard still is equipped with the overflow board, will the water storage tank divide into overflow district and play pool.
Further, the height of the overflow plate is 60-80% of the diameter of the water storage tank.
Furthermore, the length of the water storage tank is 100-180cm, and the diameter is 30-50 cm.
Furthermore, the length of the water pipe is 18-22cm, and the inner diameter of the water pipe is 1.5-2.5 cm.
Furthermore, the water pipe is connected with the water storage tank through a flow regulating valve.
Further, each water pipe is connected with 5-7 nozzles.
The utility model discloses the beneficial effect who reaches: through increasing water storage tank and inside overflow plate setting, can the effective control liquid level, guarantee the water pressure size and the hydraulic stability that spray, make each water even, guaranteed water film quality and stability of quality, through setting up flow control valve, can realize that each water is independently controllable.
Drawings
FIG. 1 is a spray assembly of conventional use;
FIG. 2 is a schematic structural diagram of the embodiment.
Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in figure 2, the etching water film spraying device with uniform water outlet comprises a cylindrical water storage tank 1, 5 groups of water pipes 2 and 5 x 7 nozzles 3 corresponding to each group of water pipes, wherein the length of the water storage tank is 110cm, the diameter of the water storage tank is 40cm, the length of each water pipe is 20cm, the inner diameter of each water pipe is 2cm, the length direction of the water storage tank is perpendicular to the advancing direction of a silicon wafer, the water pipes 2 are arranged in parallel to the length direction of the water storage tank 1 and are sequentially connected with the bottom of the water storage tank, a flow regulating valve 4 is arranged on a connecting pipeline and can independently control each water pipe, 7 nozzles are sequentially arranged at the bottom of each water pipe 2 along the length direction, a liquid level meter is arranged in the water storage tank and is used for detecting the liquid level height, a flow meter is arranged at the water inlet of the water storage tank and is used for detecting the flow, an overflow plate is arranged, can be used to control liquid level height, and then realize the control to the water pressure size, avoided the uncontrollable problem of conventional water pipe water pressure as shown in fig. 1, the overflow district still is provided with the outfall (not marked in the figure) for the flowing back, after intaking from the right side water inlet, the water that surpasss the overflow plate spills over to the left side, keeps right side liquid level height stable, ensures that water pressure is stable promptly.
By adopting the above arrangement, the problem of uncontrollable water pressure caused by the water pressure of a service end, the caliber of a pipeline, the level of a machine table and the like is avoided, uniform and controllable water outlet of each pipeline is realized, the quality of a water film can be obviously improved, over-etching, water falling and the like caused by poor quality of the water film are avoided, and therefore the etching effect is ensured, and the consumption of wet-etching chemicals is saved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
