Abstract
The utility model discloses an automatic liquid supplement device in polycrystalline silicon wafer etching. The device comprises a box. A liquid storage container is arranged in the box and sequentially connected with a metering pump and a liquid outlet arranged in the box through a pipeline, the box is further provided with a liquid adding opening communicated with the liquid storage container, and the metering pump is provided with a power regulator and a timer and controls liquid to flow out at the specific rate within setting time. The automatic liquid supplement device in polycrystalline silicon wafer etching can independently achieve the automatic liquid supplement function, carries out quantitative continuous liquid supplement, is applied to the polycrystalline silicon solar cell chained etching process and can be compatible with multiple etching devices of Rena, Schmid, Kuttler and other types in the chained etching process.
Description
Technical field
The utility model relates to a kind of automatic liquid supply device, is specifically related to a kind of polycrystalline silicon texturing automatic liquid supply device.
Background technology
In polycrystalline silicon solar cell manufacturing processed, silicon chip surface making herbs into wool is the key link.The effect of making herbs into wool has directly affected efficiency of conversion and the yield rate of final cell piece.
At solar cell, develop today of application rapidly, leather producing process and equipment thereof have become a major reason of polycrystal silicon cell development.
At present, in making herbs into wool process, due to the loss of making herbs into wool additive, need to adopt the mode of hand inspection determine whether to need supply and mend how much making herbs into wool additive, hand-manipulated wayward in supply process, also easy operational pollution, wastes time and energy.
Small part adopts the enterprise of automatic liquid supply equipment, is also the fluid infusion equipment that the integrated degree that adopts is high, be unsuitable for cutting apart use, and independence is strong not.
Utility model content
The purpose of this utility model is to provide a kind of polycrystalline silicon texturing automatic liquid supply device, it can complete independently automatic fluid filling function, carry out quantitatively continuously fluid infusion, be applicable to polycrystalline silicon solar cell chain type texturing technique, can with chain type texturing technique in multiple etching device compatible.
For achieving the above object, the technical solution of the utility model is a kind of polycrystalline silicon texturing automatic liquid supply device of design, comprise casing, in described casing, be provided with liquid storage container, described liquid storage container is connected successively volume pump and is located at the liquid outlet on casing by pipeline, on described casing, be also provided with the liquid adding hole being communicated with liquid storage container, described volume pump is furnished with power regulator and timing register, by volume pump, is controlled in setting-up time with special speed fluid.
Preferably, described liquid storage container is furnished with level probe, and described level probe connects liquid level relay, is used for detecting and controlling the liquid level of liquid storage container.
Preferably, described liquid level relay also connects warning device, when the liquid level of liquid storage container can automatic alarm when setting liquid level.
Advantage of the present utility model and beneficial effect are: a kind of polycrystalline silicon texturing automatic liquid supply device is provided, it can complete independently automatic fluid filling function, carry out quantitatively fluid infusion continuously, be applicable to polycrystalline silicon solar cell chain type texturing technique, can with chain type texturing technique in multiple etching device compatible, as Rena, Schmid, Al Kut such as strangle at the equipment.
The utility model polycrystalline silicon texturing automatic liquid supply device is connected with the acid corrosion groove of chain type texturing board, making herbs into wool additive is added in acid tank by certain flow automatic powder adding, improve sour making herbs into wool effect, strengthen making herbs into wool stability, can significantly improve the photoelectric transformation efficiency of solar cell.This equipment cost is cheap, simple in structure, good stability.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
