Abstract
The utility mode discloses a device for measuring concentricity of a silicon rod before silicon-rod butting, which comprises a fixture and a vertical post, wherein the fixture can be connected with a support seat in rotating mode, and the vertical post is fixed on the support seat vertically and is connected with a micrometer in sliding mode. During measurement, a crystal support is placed in the fixture and fixedly clamped, an adhered body of the crystal support and a raw material silicon rod is perpendicular to a working platform, then a detector of the micrometer is adjusted to be fixedly adhered to the peripheral face of the raw material silicon rod, the concentricity of the adhered body at a horizontal position can be measured by rotating the fixture once, and a mark can be made on the outside surface of the adhered body. The same measurement can be finished at another horizontal position by adjusting the height of the micrometer, and the rest can be done in the same manner to measure the whole concentricity of the adhered body quantitatively. Compared with the previous measurement of concentricity by right angle triangular rule, the device provides accurate data as a basis for concentricity adjustment of the adhered body, thereby increasing speed of the concentricity adjustment.
Description
Technical field
The utility model relates to the silicon chip processing unit (plant) in a kind of solar cell, particularly relate to a kind of raw material silicon rod before cutting into square silicon rod with the concentricity determinator of crystalline substance holder, belong to green energy resource solar energy generation technology field.
Background technology
Sun power is a kind of inexhaustible, nexhaustible green energy resource.Solar cell is the primary clustering in the solar photovoltaic generation system, and wherein monocrystaline silicon solar cell is again present a kind of solar cell with fastest developing speed, and the cutting of monocrystalline silicon piece is the key point in the monocrystaline silicon solar cell manufacturing process.Present monocrystalline silicon piece is made usually by the raw material silicon rod as original material, needs the raw material silicon rod of circle is cut into square silicon rod and four ribs of silicon rod are carried out the rounding processing before the raw material silicon rod carries out the silicon chip cutting.Before raw material silicon rod butt, need an end of raw material silicon rod is incorporated into by melt viscosity in the brilliant holder, when raw material silicon rod butt and the work of mill rib, crystalline substance is propped up clamping place into lathe, so the raw material silicon rod has determined the butt of raw material silicon rod and the quality of mill rib quality with the concentricity of brilliant holder.For guaranteeing raw silicon rib and brilliant concentricity of holding in the palm, needing that after bonding crystalline substance holds in the palm on the raw material silicon rod raw material silicon rod is carried out concentricity with brilliant holder measures, present concentricity is measured the basic original try square mensuration that adopts, promptly the adherend of crystalline substance holder and raw material silicon rod is vertically put on worktable the side, with the crystalline substance holder as benchmark, drawing square is radially pressed close to the periphery of adherend, checked whether the outer periphery of adherend is sturdy with drawing square.Though adopt this mode can find whether brilliant holder is concentric with the raw material silicon rod, the numerical value that provides its nonconcentricity that can't be quantitative, and the very inconvenience that operates.
The utility model content
For overcoming above-mentioned defective, the utility model aims to provide a kind of concentricity of mensuration raw material silicon rod and brilliant holder that can qualitative, again can be quantitative, and concentricity determinator before the silicon rod butt easy and simple to handle.
For achieving the above object, the technical solution adopted in the utility model is: concentricity determinator before a kind of silicon rod butt, it comprises anchor clamps and a root post, described anchor clamps are rotatably connected on pedestal, described column vertically is fixed on the pedestal, slidably is connected with a milscale on the described column.
Be connected with a slip cap on the described column, the level cunning is connected with a cross bar on the described slip cap, and the end of described cross bar is fixed with a milscale.
Described anchor clamps are scroll chuck.
Adopted the preceding concentricity determinator of silicon rod butt of the present utility model, during concrete mensuration, be placed on the crystalline substance holder in the anchor clamps and make brilliant holder vertical with the adherend and the worktable of raw material silicon rod, and the brilliant holder of clamping, regulate milscale then, make the outer peripheral face of the probe of milscale and raw material silicon rod sturdy, in one week of rotary clamp, can measure on the concentricity of the adherend of a horizontal level and outside surface and make mark at adherend; Regulate the height of milscale then, remake same measurement at another horizontal level, by that analogy, get final product the quantitative whole concentricity of measuring adherend, measuring concentricity with traditional drawing square compares, make the concentricity adjustment of adherend individual accurate data be arranged, accelerated the speed that concentricity is adjusted as foundation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-pedestal, 2-anchor clamps, 3-column, 4-milscale, 5-slip cap, 6-cross bar, 7-, brilliant holder, 8-raw material silicon rod.
Embodiment
As shown in Figure 1, the utility model discloses the preceding concentricity determinator of a kind of silicon rod butt, it comprises anchor clamps 2 and a root post 3, and described anchor clamps 2 are rotatably connected on pedestal 1, described column 3 vertically is fixed on the pedestal 1, slidably is connected with a milscale 4 on the described column 3.
During concrete operations, ask the crystalline substance of the adherend of crystalline substance holder and raw material silicon rod 7 ends to put into anchor clamps 2, make the end face of brilliant holder 7 sturdy, and after making the length direction of adherend and pedestal 1 vertical, clamping device 2 is clamped in the anchor clamps 2 adherend with the bottom surface of anchor clamps 2.Regulate the position of milscale 4 on column 3 then, make vertical contact of outside surface of probe with the raw material silicon rod 8 of milscale 4, and note the reading of milscale 4.Rotary clamp 2 slowly, and then drive the rotation of the adherend of brilliant holder and raw material silicon rod, and operating personnel note the variation of reading on the milscale 4, when changing the overshoot value as reading, on this some position, make mark, and the deviate that on minute book, takes reading, so that provide foundation for adjustment.After anchor clamps 2 rotate weeks, adjust the position of milscale 4 on column once more, another axial location of adherend is carried out above-mentioned work once more, measure with the concentricity of raw material silicon rod 8 until the crystalline substance holder of finishing adherend 7.
Convenient for the adjusting that makes milscale 4, be connected with a slip cap 5 on the described column 3, the level cunning is connected with a cross bar 6 on the described slip cap 5, and the end of described cross bar 6 is fixed with a milscale 4.Milscale 4 can slide up and down on column by slip cap 5 in the adjusting of short transverse and realize that milscale 4 adjusting in the horizontal direction can realize by cross bar 6 moving horizontally in slip cap 5.
Usually, described anchor clamps 2 are scroll chuck.
