Description

Battery sheet profile of tooth reference column

Technical field

The present invention relates to photovoltaic solar cell sheet manufacturing technology, specifically a kind of the battery sheet is supported and is fixed on the profile of tooth reference column on the graphite boat.

Background technology

Along with the maturation of photovoltaic solar cell sheet manufacturing technology, higher requirement is constantly proposed for the battery tablet quality.Reference column is in PECVD on the graphite boat (plasma enhanced chemical vapor deposition method) technical process battery sheet to be played support and stationary device.

The cylindrical reference column of the general employing of reference column of the prior art; Like Fig. 1, shown in Figure 2; This reference column comprises that clamp 1, upper junction plate 4, erection column 3, lower connecting plate 5 reach clamp 2 down, form the draw-in groove 6 of battery sheet respectively between last clamp 1 and the erection column 3 and between following clamp 2 and the erection column 3.Need before the pecvd process battery sheet is fixed in the draw-in groove 6 by several groups of (being generally 3 groups) reference columns; Because reference column blocks card entry slot body portion battery sheet, form hook point face territory 7, as shown in Figure 3; Technical process ionic medium body can't form the SiN film in the part that is blocked of battery sheet; Form the plated film dead angle, thereby cause battery sheet surface to have aberration, and then influence battery sheet conversion ratio and surface quality.

Reference column in use; Because getting of going round and beginning again, load make the battery sector-meeting constantly wear and tear to draw-in groove 6 bottoms of reference column; Make reference column draw-in groove 6 bottom lands deepen, wearing depth is h1, and is as shown in Figure 4; Corresponding wear area is wear surface territory 8, and wear surface territory 8 allows shielded area with the maximum with surpassing the battery sheet in hook point face territory 7.When wear surface territory 8 allows shielded area with maximum hook point face territory 7 and that surpass the battery sheet, then must change reference column, to guarantee the quality of battery sheet.

Existing cylindrical reference column, its hook point face territory 7 is bigger, allows the degree of depth h1 of wearing and tearing less, and useful life is short, changes frequent.

Summary of the invention

The present invention is directed to the problems referred to above, a kind of long service life, long battery sheet profile of tooth reference column of replacement cycle are provided.

According to technical scheme of the present invention: a kind of battery sheet profile of tooth reference column; Comprise that the last clamp, upper junction plate, erection column, the lower connecting plate that link to each other successively reach clamp down; Form draw-in groove respectively between said last clamp and the said erection column and between said clamp down and the said erection column, said going up on clamp and the said following clamp has the perforation that communicates with the said draw-in groove of side.

Said perforation on said perforation on the said upward clamp and the said clamp down has one or more respectively.Said a plurality of perforation is distributed on respectively saidly to be gone up on the clamp or on the said clamp down.Said a plurality of perforations on the said upward clamp on the perhaps said clamp down are respectively two or four.Said perforation on the said last clamp is distinguished corresponding setting with the said perforation on the said clamp down.Said perforation be shaped as rectangle.

Said upper junction plate, said erection column and said lower connecting plate are coaxial cylinder, and said upward clamp and said clamp down are the Rotary-table coaxial with said erection column, and the bigger diameter end of said Rotary-table is positioned at the outside.

Said upward clamp and the said big footpath of clamp down are less than or equal to said cylindrical diameter.

Technique effect of the present invention is: the present invention reaches down at clamp on the reference column and has perforation on the clamp; Can reduce the shielded area of reference column to the battery sheet; Increase the permission wearing depth of reference column; Improve the conversion ratio and the surface quality of battery sheet, increase the useful life of reference column, prolong its replacement cycle.

Embodiment

Be further described below in conjunction with the accompanying drawing specific embodiments of the invention.

Among Fig. 1 ~ Fig. 9, comprise clamp 1, following clamp 2, erection column 3, upper junction plate 4, lower connecting plate 5, draw-in groove 6, hook point face territory 7, wear surface territory 8, perforation 9, hook point face territory 10, wear surface territory 11 etc.

Like Fig. 5 ~ shown in Figure 7; The present invention is a kind of battery sheet profile of tooth reference column; Comprise that the last clamp 1, upper junction plate 4, erection column 3, the lower connecting plate 5 that link to each other successively reach clamp 2 down, form draw-in groove 6 respectively between last clamp 1 and the erection column 3 and between following clamp 2 and the erection column 3.Upper junction plate 4, erection column 3 and lower connecting plate 5 are coaxial cylinder, last clamp 1 and down clamp 2 be the Rotary-table coaxial with erection column 3, and outside the bigger diameter end of Rotary-table is positioned at.Last clamp 1 reaches down, and the big footpath of clamp 2 is less than or equal to cylindrical diameter.

The present invention is at last clamp 1 and have the perforation 9 that communicates with the draw-in groove 6 of side on the clamp 2 down.Perforation 9 on the last clamp 1 and down the perforation 9 on the clamp 2 one or more is arranged respectively, the corresponding settings of perforation 9 difference on the perforation 9 on the last clamp 1 and the following clamp 2, a plurality of perforations 9 are distributed on respectively on the clamp 1 perhaps down on the clamp 2.Being shaped as of perforation 9 is preferably rectangle.

Shown in Figure 5 is to have a perforation 9 on the clamp 2 under last clamp 1 reaches, and shown in Figure 6 is to have two perforations 9 on the clamp 2 under last clamp 1 reaches, and shown in Figure 5 is to have four perforations 9 on the clamp 2 under last clamp 1 reaches.

Operation principle of the present invention is following: like Fig. 8 and shown in Figure 3; When the battery sheet is fixed on the profile of tooth reference column that has perforation 9; Compare with the cylindrical reference column of same specification, the hook point face territory 10 of profile of tooth reference column is less than the area of 7 one perforations 9 in hook point face territory of cylindrical reference column, therefore; The profile of tooth reference column is little to the shielded area of battery sheet, can improve the conversion ratio and the surface quality of battery sheet.

Like Fig. 9 and shown in Figure 4; Because it is certain value that the maximum of battery sheet allows shielded area; Therefore, the wear surface territory 11 of profile of tooth reference column is greater than the wear surface territory 8 of cylindrical reference column, and promptly the permission wearing depth h2 of profile of tooth reference column is greater than the permission wearing depth h1 of cylindrical reference column; Thereby can increase the useful life of profile of tooth reference column, prolong its replacement cycle.
