Description
Technical field
The utility model relates to solar battery sheet production technical field, particularly relates to a kind of for Novel graphite boat during PECVD.
Background technology
Along with the fast development of photovoltaic solar industry, the demand of market to solar battery sheet also constantly increases, graphite boat is a kind of important equipment of PECVD (plasma reinforced chemical vapour deposition) technique, solar-energy photo-voltaic cell enterprise in daily production all can due to some improper operations cause sintering after battery silicon chip occur that edge collapses limit, all outward appearance can be affected as white collapses the cell piece that can cause on limit, reduce qualification rate, the cell piece of this type is once produce, solar energy enterprise does not have treating method yet, can only avoid occurring that white collapses limit as far as possible, and white collapses, and limit sheet mainly causes due to PE workshop section unloading piece in graphite boat, when unloading piece slice, thin piece easily bump against above ceramic bar and produce and collapse limit phenomenon.
Existing graphite boat is formed by assemblings such as graphite boat piece, ceramic bar, earthenware, graphite nuts usually in addition, each graphite boat piece has corresponding multiple manholes, each graphite boat piece is fixedly connected into boat body by the ceramic bar be applied in manhole, ceramic bar between adjacent two panels graphite boat piece is set with earthenware, and the two ends of each ceramic bar are fixed in outermost two panels graphite boat piece by graphite nut.Ceramic bar and earthenware need be separated operation during the graphite boat dismounting of this structure, workman needs repetition dismounting action up to a hundred times, this considerably increases workload; Ceramic bar is penetrated in the through hole of each graphite boat piece simultaneously, to the circularity of graphite boat piece through hole and the requirement of position degree high, add the difficulty of dismounting graphite boat, reduce operating efficiency.
Utility model content
In order to solve the technical problem of above-mentioned existence, the utility model provides a kind of Novel graphite boat, and the white for solving this type of solar cell collapses limit problem, and raising qualification rate and AO lead, and concrete technical scheme is:
A kind of Novel graphite boat, it is characterized in that: comprise multi-disc graphite boat piece arranged side by side 2, described multi-disc graphite boat piece 2 connects into boat body by upper end ceramic bar 1, lower end ceramic bar 8 and graphite nut 4, described upper end ceramic bar 1 quantity is four, described lower end ceramic bar 8 quantity is seven, the edge of described multi-disc graphite boat piece 2 has corresponding U-type groove hole 6, described ceramic bar 1 and lower end ceramic bar 8 are provided with multiple draw-in groove 7, described ceramic bar 1 and lower end ceramic bar 8 are installed in described U-type groove hole 6, and described draw-in groove 7 is stuck in each described graphite boat piece 2.
The utility model compared with prior art has following technique effect: the utility model is first by reducing the quantity of the ceramic bar connecting graphite boat piece, when saying that crystal silicon chip shifts out from graphite boat piece, reduce the quantity that white collapses limit, raising qualification rate and AO lead, thus finally improve economic benefit, U-type groove hole is had in addition in graphite boat piece, ceramic bar is provided with draw-in groove, effect that is fixing and insulation graphite boat piece is reached by U-type groove hole ceramic bar directly being put into graphite boat piece, easy to operate, workload can be reduced, other structure of increasing work efficiency is simple, reasonable in design, workable, be worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model (display upper end ceramic bar 1);
Fig. 2 of the present utility modelly looks up structural representation (display lower end ceramic bar 8);
Fig. 3 is the structural representation of graphite boat piece in the utility model.
Embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of Novel graphite boat, comprise multi-disc graphite boat piece arranged side by side 2, described multi-disc graphite boat piece 2 connects into boat body by upper end ceramic bar 1, lower end ceramic bar 8 and graphite nut 4, described upper end ceramic bar 1 quantity is four, described lower end ceramic bar 8 quantity is seven, the edge of described multi-disc graphite boat piece 2 has corresponding U-type groove hole 6, described upper end ceramic bar 1 and lower end ceramic bar 8 are provided with multiple draw-in groove 7, described upper end ceramic bar 1 and lower end ceramic bar 8 are installed in described U-type groove hole 6, and described draw-in groove 7 is stuck in each described graphite boat piece 2.
By reducing the quantity of the ceramic bar connecting graphite boat piece, seven ceramic bars being positioned at upper end are reduced to four, when crystal silicon chip is shifted out from graphite boat piece, reduce the quantity that white collapses limit, raising qualification rate and AO lead, thus finally improve economic benefit, have U-type groove hole in addition in graphite boat piece, ceramic bar is provided with draw-in groove, reaches effect that is fixing and insulation graphite boat piece by U-type groove hole ceramic bar directly being put into graphite boat piece.
The above; be only this practicality preferably embodiment; but the utility model protection range is not limited thereto, is equal to according to the technical solution of the utility model and inventive concept thereof and replaces or change, all should be encompassed within protection range of the present utility model.
