Abstract

The utility model relates to a dedicated supporting tool used in the square silicon slice coating technology, in particular to a supporting frame used for silicon slice coating. Two vertically upward connecting arms used for clipping graphite sash strips are arranged at both ends of a cross supporting arm of the supporting frame; outward inclined support legs are arranged at the lower ends of the connecting arms; after the upper ends of the two connecting arms are kneaded mutually, the supporting frame is clipped on the graphite sash strips. By using the supporting frame, supporting contact points of the of the original supporting frames such as a supporting hook, etc. on the disk surface of the bottom surface of the silicon slice are transferred to on the edge of the bottom surface of the square silicon slice; therefore, a membraneless imprint formed on the disk surface of the bottom surface of the silicon slice can be eliminated after the silicon slice is coated, and the coating quality and the coating effect are improved, so that the adverse affect to the performance of a prepared solar energy cell slice caused by the membraneless imprint is eradicated.

Description

The silicon chip film-coated bracing frame of using

Technical field

The utility model relates to the special-purpose bearing tool that uses in a kind of square silicon chip film-coated technology, specifically a kind of silicon chip film-coated bracing frame of using.

Background technology

The square silicon chip of making solar battery sheet will be placed in the graphite frame square hole before plated film, and is supported by a part that is fixed on the glazing bar of square hole both sides.Because a part is to the support of silicon chip bottom surface, make and to form plated film at this fulcrum place, these no film places have just influenced the coating effects of square silicon chip, so after the plated film silicon chip was made solar battery sheet, these no film places will produce certain adverse effect to the performance of solar battery sheet.

The ZL200720101557.X patent is the applicant obtains power in first to file a kind of silicon chip film-coated support hook of using.This support hook is to be molded into along the " of axis symmetry with stainless steel spring steel wire, and two bills of coupler body bottom are upwards crooked, becomes the tip shape.Because the bill of tip shape and silicon chip bottom surface are to contact, thereby when silicon chip film-coated, bill and silicon chip bottom surface join the no film marking that the place, contact forms with regard to the corresponding minimum zone that narrows down to, thus to the adverse effect of made solar battery sheet also with regard to the corresponding Min. that is reduced to.Though influence has dropped to minimum, owing to support the existence of contact point, thereby influence also can't thoroughly be eliminated.

The utility model content

The purpose of this utility model just provides a kind of not at the silicon chip film-coated bracing frame of using of the card upper support of silicon chip bottom surface, to improve silicon chip film-coated quality, eliminates the existence of the no film marking and the adverse effect that is produced.

The utility model is achieved in that a kind of silicon chip film-coated bracing frame of using, and this bracing frame is to be provided with two linking arms that are used for snapping graphite sash bar straight up at horizontal trailing arm two ends, and the lower end of linking arm is outer tiltedly leg.

This bracing frame is pushed away below the glazing bar of graphite frame, and horizontal trailing arm withstands on the bottom surface of glazing bar, and two linking arms protrude upward from the glazing bar both sides, and the part quilt that exceeds the glazing bar end face is kneaded together mutually, thereby the bracing frame snapping is fixed on the graphite sash bar.Two outer tiltedly legs of bracing frame linking arm lower end lay respectively in two adjacent graphite frame square holes.Be fixed with two bracing frames respectively on two opposite side glazing bars of each graphite frame square hole, the outer oblique leg on the bracing frame of both sides is relative, supports the square silicon chip that is placed in this graphite frame square hole together.When square silicon chip is put into certain graphite frame square hole, be positioned at the bottom edge that four outer tiltedly legs on four bracing frames of this square hole just can withstand on these square silicon chip two opposite side, support this square silicon chip thus.

The utility model has been transferred to the support contact point of supports such as original support hook on the card of silicon chip bottom surface on the bottom edge of square silicon chip, so just can eliminate the formed no film marking on the card of silicon chip bottom surface in silicon chip film-coated back, improved the coating quality and the coating effects of silicon chip thus, the feasible adverse effect to made solar cell piece performance that is caused by the no film marking is thoroughly eliminated.

In addition, because four outer tiltedly legs on each graphite frame square hole inner support frame are supporting constructions relative, wide at the top and narrow at the bottom in twos, therefore, can form stable support to silicon chip, and, do not move this stable support structure because can not making silicon chip produce laterally, so just can save original, prevent the position-limit mechanism that silicon chip laterally moves, make the corresponding simplification of structure.And this stable support structure wide at the top and narrow at the bottom also can carry the bigger silicon chip of the margin of tolerance, also can reduce the machining accuracy and the corresponding processing cost of silicon chip thus.

Below in conjunction with accompanying drawing the utility model is further described.

Embodiment

As shown in Figure 1, this is novel silicon chip film-coatedly to have a horizontal trailing arm 1 with bracing frame, be provided with two linking arms 2 straight up at the two ends of horizontal trailing arm 1, the end face of graphite sash bar 4 is stretched out also by kneaded together mutually, this bracing frame is snapped onto on the graphite sash bar 4 in the upper end of linking arm 2.The lower end of linking arm 2 is outer tiltedly leg 3, and two of bracing frame both sides are outer, and tiltedly legs are symmetrical, square silicon chip 5 be on outer oblique leg 3 end faces of lower limb and both sides bracing frame by its both sides, bottom surface certain any contact to be stabilized and support.

Claims

1, a kind of silicon chip film-coated bracing frame of using is characterized in that this bracing frame is to be provided with two linking arms (2) that are used for snapping graphite sash bar straight up at the two ends of horizontal trailing arm (1), and the lower end of linking arm (2) is outer tiltedly leg (3).
