Abstract
The invention discloses a transmission and air-drying structure of a polycrystalline silicon wafer flocking machine. The transmission and air-drying structure comprises a rotatable transmission shaft, joints, rollers and downwind openings. The joints are equidistantly arranged along the axial direction of the transmission shaft, radial sizes of the joints are identical, the middle of a connecting shaft section between each two joints is circumferentially protruded to form the corresponding roller, the axial length of each roller is larger than the side length of a polycrystalline silicon wafer, the circular or long and narrow downwind openings are arranged below the rollers, and the polycrystalline silicon wafer is in linear contact with the rollers. The lower surface of the polycrystalline silicon wafer can be quickly air-dried under the action of air knives blown out from the downwind openings after the polycrystalline silicon wafer is discharged from a flocking groove, roller marks are prevented, and the appearance qualified rate of the manufactured polycrystalline silicon wafer is increased.
Description
Technical field
the present invention relates to transmission and the air drying structure of polycrystalline silicon texturing machine.
Background technology
general employing polycrystalline silicon texturing machine is produced in the making herbs into wool of polysilicon solar battery slice, polycrystalline silicon texturing facility have texturing slot, alkali pond, exhausting, transmission and the air drying structure of polycrystalline silicon texturing machine comprise roller, upper air knife, the middle part of every section of power transmission shaft is circumferentially in outward direction convexes to form roller, the axial length of roller is no more than the length of side of polysilicon chip, the both ends of roller respectively circumferentially each self-forming one of projection in outward direction enclose the edge for supporting polysilicon chip, what the kind of drive adopted is linked transmission, many power transmission shaft parallel arrangements also rotate, polysilicon chip to be placed on roller and to be transmitted, polysilicon chip is successively through texturing slot, alkali pond, at texturing slot, the upper air knife be positioned at above roller is set between alkali pond, for the chemical liquid of polysilicon chip remained on surface is dried up, because upper air knife blows the lower surface less than polysilicon chip, therefore the lower surface of polysilicon chip still can continue chemical reaction occurs, the contact area of polysilicon chip and roller is less, and the liquid in the place contacted also can be less than the liquid in other place of lower surface relatively, polysilicon chip leave texturing slot to enter alkali pond during this period of time in, the chemical reaction that place that on lower surface, liquid is many occurs is more than the chemical reaction at polysilicon chip and roller contact place, polysilicon chip lower surface can form obvious rolling wheel stamp, have impact on polysilicon chip make after appearance yield.
Summary of the invention
the object of this invention is to provide and the lower surface of polysilicon chip can be avoided to form rolling wheel stamp, improve polysilicon chip make after the transmission of polycrystalline silicon texturing machine of appearance yield and air drying structure.
for achieving the above object, the technical solution used in the present invention is: the transmission of polycrystalline silicon texturing machine and air drying structure, described drive mechanism comprises the rotating power transmission shaft for polysilicon chip described in transmission, equidistantly be distributed in the multiple connecting joints on described power transmission shaft axial direction, described air drying structure comprises the uptake that outwards can blow air knife be arranged on above described power transmission shaft, described power transmission shaft is divided into isometric multistage sections by described connecting joint, the middle part circumferentially roller of outwardly convex formation in direction for supporting described polysilicon chip of one section of described power transmission shaft sections between every two described connecting joints, described air drying structure also comprises the lower air port that outwards can blow the air knife of the lower surface for the described polysilicon chip of drying of the below being arranged on described roller.
preferably, described power transmission shaft, described connecting joint are coaxially arranged, and the radial dimension of described connecting joint is greater than the radial dimension of described roller, and the axial dimension of described roller is greater than the length of side of described polysilicon chip.
preferably, described uptake, described lower air port are circular or thin-and-long.
due to the utilization of technique scheme, the present invention compared with prior art has following advantages: the middle part of every section of power transmission shaft is circumferentially in outward direction convexes to form roller, the axial length of roller is greater than the length of side of polysilicon chip, the contact area of the lower surface of silicon chip and the outer peripheral face of roller is larger, except the uptake be arranged on above roller, the lower surface had additional in the below of roller to polysilicon chip blows the lower air port of air knife, polysilicon chip by texturing slot out after, to be in the wind mouth, under the effect in lower air port, the chemical liquid of remained on surface is dried very soon, the lower surface of such polysilicon chip can not form rolling wheel stamp, improve polysilicon chip make after appearance yield.
Accompanying drawing explanation
accompanying drawing 1 is the structural representation of power transmission shaft of the present invention;
accompanying drawing 2 is the structural representation in lower air port of the present invention.
Embodiment
structure of the present invention is set forth further below in conjunction with accompanying drawing.
shown in Figure 1, power transmission shaft 1 can constantly rotate, in practice, the parallel power transmission shaft that many rows are contour is set, polysilicon chip is driven to advance during rotation, the axial direction of power transmission shaft 1 is evenly provided with connecting joint as 2, power transmission shaft 1 is separated for multiple isometric power transmission shaft sections is as 5 as 2 by connecting joint, each power transmission shaft sections as 5 middle part circumferentially the roller that convexes to form in outward direction as 3, the axial length of roller as 3 is greater than the length of side of polysilicon chip, such roller is long linear contact lay as what occur between 3 and polysilicon chip, change traditional edge by two ends to contact and then support with polysilicon chip generation short line segment and the mode of transmission polysilicon chip, under the mode of long linear contact lay, the roller of the weight uniformity distribution of polysilicon chip is as on 3, the radial dimension of connecting joint as 2 be greater than roller as 2 radial dimension, the radial dimension of multiple connecting joint as 2 is identical, ensure that the stationarity of multiple roller as 3 transmissions.
shown in Figure 2, in the below of roller as 3, lower air port is set as 4, lower air port is arranged horizontal by 30 degree of angles as 4, air knife is blowed in face of the in outward direction of polysilicon chip transmission, polysilicon chip by texturing slot out after, in lower air port as under the air knife effect of 4 blowouts, lower surface is air-dry very soon, set up lower air port as after 4, lower air port as 4 and roller as 3 above arrange uptake mating reaction, can by air-dry for its whole outer surface before polysilicon chip enters alkali pond, the shape of lower air port as 4 is circular or thin-and-long, the air knife of the lower air port blowout of thin-and-long is powerful, in the present embodiment, lower air port is set to circle as 4, the air knife of blowout is even, serve good air-dry effect, the lower surface avoiding polysilicon chip forms rolling wheel stamp, improve polysilicon chip make after appearance yield.
