Abstract
The utility model discloses a novel graphite boat device capable of preventing a silicon slice from dropping down. The novel graphite boat device comprises graphite boat slices, ceramic rods, and process points, wherein the graphite boat slices are arranged in an equal space in parallel, the upper edge of each graphite boat slice is equally divided into N parts; the lower edge of the graphite boat slice is equally divided into N+1 parts, the distances between first ceramic pipes on the two ends of the lower edge and the adjacent ceramic pipes are different, and the distances between the two adjacent ceramic pipes on the middle positions are same; the graphite boat slices are fixed by the ceramic pipes perpendicular with the graphite boat slices on the decipoint position; the relatively long distance between the corresponding points of any one ceramic pipe on the lower end of the graphite boat and the adjacent ceramic pipe on the upper edge is smaller than the size of the silicon slice. The novel graphite boat device has the following beneficial effects: the fragmentation rate is reduced, the production efficiency is improved, and the production cost is saved.
Description
Technical field
The utility model relates to crystal silicon solar batteries and makes the field, relates to particularly the graphite boat device that a kind of novel anti-silicon chip drops.
Background technology
In the production technology PECVD of crystal silicon solar batteries sheet process, at first need silicon chip is inserted in the graphite boat, silicon chip is fixing by three process point on the graphite boat (graphite nail), passes through material loading again, advances boat, and the processes such as heating are finished coating process.If silicon chip is not put into the position or itself has hidden splitting, in the situation through high temperature and high-frequency discharge in boiler tube, will so that the silicon chip that originally is stuck on the graphite boat process point drop.In case silicon chip drops, run into adjacent silicon chip and short circuit phenomenon will occur, produce high frequency and report to the police.When the machine high frequency was reported to the police, machine can withdraw from graphite boat automatically, and in the process that withdraws from, need to take out by the slurry that machine carries.In the time of in slurry enters boiler tube, the silicon chip that falls down can be smashed to pieces, and the silicon chip of smashing to pieces can relatedly be smashed silicon chip on every side to pieces.According to statistics, machine alarm once can cause 4 to 6 of fragments.Therefore, the project organization of existing graphite boat not only affects production efficiency, and has increased production cost.
Summary of the invention
The purpose of this utility model provides the graphite boat device that a kind of novel anti-silicon chip drops, and solves the problem that often can occur fragment in the existing graphite boat use procedure.
The technical solution of the utility model is the graphite boat device that a kind of novel anti-silicon chip drops, and comprises the graphite boat sheet, earthenware, and process point, wherein the graphite boat sheet is arranged in mode parallel to each other and that spacing equates; Each graphite boat sheet top edge is divided into the N equal portions; The lower limb of graphite boat sheet is divided into N+1 part, and the distance that first earthenware at lower limb two ends is adjacent between earthenware is different, and the distance between adjacent two earthenwares in centre position is identical; Use the earthenware vertical with the graphite boat sheet that the graphite boat sheet is fixed at the branch place; Any one earthenware of graphite boat lower end to distance long between the top edge earthenware corresponding points that are adjacent all less than the size of silicon chip.
The beneficial effects of the utility model are to reduce fragment rate, enhance productivity, and save production cost.
Description of drawings
The end view of the graphite boat device that the novel anti-silicon chip that Fig. 1 provides for the utility model drops
1 represents earthenware among the figure; 2 represent process point; A is the earthenware of graphite boat sheet lower limb left end and the distance between the adjacent ceramic pipe; B is the distance between adjacent two earthenwares of mediating of graphite boat sheet lower limb; C is the earthenware of graphite boat sheet lower limb right-hand member and the distance between the adjacent ceramic pipe; D is the distance between adjacent two earthenwares of graphite boat sheet top edge; E is that any one earthenware of graphite boat lower end is to distance long between the top edge earthenware corresponding points that are adjacent.
Embodiment
Below in conjunction with accompanying drawing technical solutions of the utility model are elaborated.
1. the graphite boat device that designs in the present embodiment is comprised of 20 graphite boat sheets and 15 earthenwares.
2. graphite boat sheet top edge is divided into six equal portions, and the distance B between adjacent two earthenwares is 175mm.
3. graphite boat sheet lower limb is divided into into seven parts, wherein the distance A between first earthenware of left end and adjacent ceramic pipe is 151.5mm, distance C between first earthenware of right-hand member and adjacent ceramic pipe is 23.5mm, between adjacent two earthenwares that graphite boat sheet lower limb mediates is 175mm apart from B, and any one earthenware of graphite boat lower end is 151.5mm to what grow between the top edge earthenware corresponding points that are adjacent apart from E.
It should be noted last that, above embodiment is only unrestricted for the explanation the technical solution of the utility model, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the claim scope of the present utility model.
Claims (3)
1. the graphite boat device that novel anti-silicon chip drops comprises the graphite boat sheet, ceramic rod, and process point is characterized in that: described graphite boat sheet is arranged in mode parallel to each other and that spacing equates; Each graphite boat sheet top edge is divided into N part, and the lower limb of graphite boat sheet is divided into N+1 part; Use the earthenware vertical with the graphite boat sheet that the graphite boat sheet is fixed at the branch place.
2. the graphite boat device that drops of a kind of novel anti-silicon chip according to claim 1, it is characterized in that: each graphite boat sheet top edge is divided into the N equal portions, first earthenware at lower limb two ends is adjacent the distance (A between earthenware, C) difference, the distance (B) between adjacent two earthenwares in centre position is identical.
