Abstract
The utility model provides a solar battery slice etching device which comprises a roller support clamping groove and rollers, wherein the roller support clamping groove is arranged in a device etching groove; the rollers are installed on the support clamping groove and are of high-low alternating arrangement structures; the high-low alternating arrangement of the rollers is formed by the high-low alternating arrangement of support positions installed on the support clamping groove of the rollers with equal diameter, or is formed by the alternating arrangement of the rollers with different diameters, installed on the support clamping groove; and the adjacent high-low alternating height difference of the rollers is maximally not greater than the two fifths of the diameter of each roller, and the adjacent high-low alternating height difference of the rollers is minimally not less than 0.1mm. The solar battery slice etching device provided by the utility model is simple and reliable in structure, on the conventional etching machine, the high-low roller etching is realized only through regulating the support heights of the support clamping groove of the rollers in the etching groove or mounting the rollers with the different diameters, the product quality is improved, and the production cost is lowered.
Description
Technical field
The utility model relates to the equipment in a kind of manufacture of solar cells, particularly the solar battery sheet Wet-method etching device.
Background technology
In the production process of crystal-silicon solar cell, etching is the important procedure of preparation crystalline silicon solar cell piece, its objective is that the PN junction with silicon chip back of the body surface and periphery removes, and need guarantee that simultaneously the positive PN junction of battery sheet is not destroyed.At present, wet etching equipment is stained with the form of liquid and is taken etching liquid to the silicon chip back side (non-diffusingsurface) in being widely used in producing through roller like SCHMID etching machine, through chemical reaction the PN junction at the back side and edge is removed, and the positive and negative PN junction is broken off, and reduces electric leakage.But all rollers in its etching groove are all at sustained height; And the external diameter of all rollers is all the same; Silicon chip carries out the etching of the back side and side in same plane motion; Because the etching liquid surface tension and with the contact problems of silicon chip, cause one side etching effect of silicon chip direction of advance not good, and cause the electric leakage of battery sheet easily.
The utility model content
The purpose of the utility model is to provide a kind of solar battery sheet etching device, through the support draw-in groove of adjustment existing equipment etching groove internal trolley, or through the roller of different-diameter is installed, realizes height roller etching, improves the quality of products, and reduces production costs.
The technical scheme of the utility model is: a kind of solar battery sheet etching device, comprise that the roller that is arranged in the equipment etching groove supports draw-in groove, and roller, wherein, said roller is installed on the said support draw-in groove, is alternately arrangement architecture of height.
It is that roller by same diameter is installed in Support Position on the said support draw-in groove and just alternately arranges and constitute that the height of said roller is alternately arranged.
It is alternately to be arranged by the roller that is installed in different-diameter on the said support draw-in groove to constitute that the height of said roller is alternately arranged.
Said roller just replaces adjacent difference in height maximum and is no more than 2/5ths of roller diameter, and minimum is not less than 0.1mm.
The utility model on existing etching apparatus, the bearing height of the support draw-in groove through adjustment etching groove internal trolley, or, realize height roller etching through the roller of different-diameter is installed.Realize height fluctuating " wave " formula operation of silicon chip on the roller; Strengthened total contact area of silicon chip and etching groove internal trolley; Etching is carried out on the surface that makes etching solution touch silicon chip more easily; Improve product percent of pass, do not needed other making apparatus part simultaneously, also do not had special fitting operation.
Description of drawings
Fig. 1 is the utility model same diameter roller etching groove inner structure sketch map;
Fig. 2 is the utility model different-diameter roller etching groove inner structure sketch map;
Among the figure: 1-etching groove, the 2-solar battery sheet, the 3-roller, 4-supports draw-in groove, the difference in height between the 5-height roller, 6-roller.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
Like Fig. 1,2, a kind of solar battery sheet etching device that the utility model provides comprises that the roller that is arranged in the equipment etching groove 1 supports draw-in groove 4, roller 3, and wherein, said roller 3 is installed on the said support draw-in groove 4, is alternately arrangement architecture of height.
Preferably, alternately to arrange be that roller 3 by same diameter is installed in Support Position on the said support draw-in groove 4 and just alternately arranges and constitute to the height of said roller.
Preferably, alternately to arrange be alternately to be arranged by the roller 3 that is installed in different-diameter on the said support draw-in groove 4, roller 6 to constitute to the height of said roller.
Preferably, said roller just replaces adjacent difference in height 5 maximums and is no more than 2/5ths of roller 3 diameters, and minimum is not less than 0.1mm.
The utility model is transformed on existing etching machine; The height of roller alternately is a permutation and combination arbitrarily; Continuous alternate combinations structure such as 1 high roller and 1 low roller; Or the continuous alternate combinations structure of continuous 4 high rollers and 4 low rollers, or the continuous alternate combinations structure of continuous 5 high rollers and 3 low rollers, or the continuous alternate combinations structure of continuous 3 high rollers and 5 low rollers.Main purpose is to realize height fluctuating " wave " formula operation of silicon chip in the etching groove.
The utility model is simple in structure, reliable; On existing etching machine, only need bearing height through the support draw-in groove of adjustment etching groove internal trolley, or through the roller of different-diameter is installed; Realize height roller etching; Transform simply, do not need other making apparatus part, also do not have special fitting operation.Realize height fluctuating " wave " formula operation of silicon chip on the roller, strengthened total contact area of silicon chip and etching groove internal trolley, etching is carried out on the surface that makes etching solution touch silicon chip more easily, has improved product percent of pass, has reduced production cost.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
