Abstract
The utility model discloses a diffusing quartz boat device used for manufacturing solar cells, which comprises a quartz boat body and two boat forks matched with the quartz boat body. The quartz boat body includes two upright side frames and a plurality of bottom bars and side bars, wherein the bottom bars and the side bars are vertically connected between the two upright side frames; the top end of the side frame is provided with a boat fork hole; the boat fork comprises a steel handle and an insert tube, and a heat insulation tube made of quartz is sleeved outside the insert tube; both ends of the boat fork hole are provided with an inclined plane; the height of the side frame is between a half and two thirds of the width of the side frame; an isolation block is arranged between the handle and the insert tube of the boat fork; and a buffer gasket is arranged on a surface, which faces towards the insert tube, of the isolation block. The boat forks are inserted into the boat fork holes more easily because both ends of the boat fork holes are provided with the inclined surface structure; the height of the quartz boat body is reduced so as to enable the quartz boat to have better stability; the isolation block is arranged between the handle and the insert tube of each boat fork so as to prevent the hands of an operator from being scalded by a high-temperature quartz boat.
Description
Technical field
The utility model relates to a kind of production equipment of solar cell, relates to a kind of quartz boat device that when the phosphorous diffusion of photovoltaic crystal silicon cell production process, is adopted specifically.
Background technology
In existing photovoltaic crystal silicon cell production process, diffusion preparation PN junction is very crucial one procedure.No matter be to adopt the chain type diffusion furnace or tubular diffusion furnace spreads the preparation PN junction; All need adopt quartz boat to be used for carrying silicon chip; And in the temperature of diffusion furnace usually more than 850 ℃, diffusing procedure is very high to the requirement of cleanliness factor simultaneously, so; Also the boat of a special use of needs is pitched quartz boat is moved; Existing diffusion quartz boat is generally one by the boat shape framework of quartz making and two boats forks that match with it, wherein mainly comprises two limit framves and be connected in some bottom bars, the side lever between two limit framves that the upper end of frame has two boat entries on the limit; Existing boat fork is mainly by the fork body that comprises handle and intubate of a steel, is surrounded by quartz ampoule in the periphery of intubate.But mainly there is following defective in existing diffusion quartz boat device: one, its highly common phasing wide with it is same, less stable when placing; Two, the axis of the opening part of its boat entry and boat entry is perpendicular, makes the boat fork insert comparatively difficulty; Three, do not have safeguard procedures between the handle of boat fork and the intubate, the boat fork is when inserting the boat entry, and operating personnel's hand is scalded by the quartz boat of high temperature easily.
The utility model content
For overcoming above-mentioned defective, that the utility model aims to provide is a kind of not only convenient, but also the manufacture of solar cells of safety with the diffusion quartz boat.
For achieving the above object; The technical scheme that the utility model adopts is: a kind of manufacture of solar cells is with diffusion quartz boat device; Comprise quartz boat body and two boat forks that match with it; Said quartz boat body comprises two upright limit framves and vertically is connected in some foundation bars and the side lever between two limit framves that the Xiang Duan of said limit frame has a boat entry; Said boat fork comprises the handle and the intubate of steel, and said intubate is wrapped with the instlated tubular of the quartzy material of one deck; Two ends of said boat entry have an inclined-plane.
The height of said limit frame is the 1/2-2/3 of its width.
Be provided with a spacing block between the handle of said boat fork and the intubate, said spacing block is provided with a cushion pad towards the face of intubate 22.
The manufacture of solar cells that has adopted the utility model owing to be provided with ramp structure at two ends of boat entry, makes the boat fork more be prone to be inserted in the boat entry with diffusion quartz boat device; Reduced the height of quartz boat body, made quartz boat have better stability; And between the handle of boat fork and intubate, spacing block is set, prevent that operating personnel's hand from being scalded by the quartz boat of high temperature.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of limit frame of the quartz boat body of the utility model;
Fig. 3 is the structural representation of the boat fork of the utility model.
Among the figure: 1-quartz boat body, 2-boat fork, 11-limit frame, 12-bottom bar, 13-side lever, 14-boat entry, 15-inclined-plane, 21-handle, 22-intubate, 23-instlated tubular, 24-spacing block, 25-cushion pad.
Embodiment
Like Fig. 1-shown in Figure 3; The utility model discloses a kind of manufacture of solar cells with diffusion quartz boat device; Comprise quartz boat body 1 and two boat forks 2 that match with it; Said quartz boat body 1 comprises two upright limit framves 11 and vertically is connected in the some foundation bars 12 and side lever 13 between two limit framves 11; Said limit frame 11, bottom bar 12 and side lever 13 are made by quartzy material, and the cavity that said limit frame 11, bottom bar 12 and side lever 13 surround a boat shape is used to carry silicon chip and spreads the preparation PN junction, and the Xiang Duan of said limit frame 11 has a boat entry 14; Said boat fork 2 comprises the handle 21 and intubate 22 of steel, and said intubate 22 is wrapped with the instlated tubular 23 of the quartzy material of one deck; Usually has stability preferably when making boat fork 2 insert boat entries 14 holes; The external diameter of 22 outer field instlated tubulars 23 of intubate of said boat fork 2 can only be slightly less than the internal diameter of boat entry 14, and the innovative point of the utility model is that mainly two ends of said boat entry 14 have an inclined-plane 15.Because the setting on inclined-plane 15 increases the openend area of boat entry 14, boat fork 2 is easier to insert.
In order to make quartz boat body 1 when placing, have better stability, another innovative point of the utility model is exactly the 1/2-2/3 that is made as the height of said limit frame 11 its width.Like this, on the whole, the decline again of quartz boat body 1, thus make it have better stability.
Another innovative point of the utility model also is to be provided with a spacing block 24 between handle 21 and the intubate 22 of said boat fork 2, and said spacing block 24 is provided with a cushion pad 25 towards the face of intubate 22.Owing to the effect of spacing block 24, when moving, there is spacing block 24 to be isolated between the silicon chip of the quartz boat body 1 of operating personnel's hand and high temperature and upward carrying thereof when boat fork 2 insertion boat entries 14 and quartz boat body 1, the personnel that can not cause scald.And a cushion pad 25 is set on the face of intubate 22 at spacing block 24, can avoid as much as possible colliding between instlated tubular 23 and the boat entry 14 of frangible quartzy material and break.
