Abstract
The utility model discloses a silicon rod workpiece of a multi-wire cutting machine, which relates to the field of cutting machines for cutting monocrystal silicon rods and polycrystal silicon rods in a multi-wire way. The silicon rod workpiece of the multi-wire cutting machine comprises a silicon rod, wherein the bottom of the silicon rod is adhered with two resin strips; the two resin strips are respectively arranged on two sides of the width direction of the silicon rod; and the length of each resin strip is respectively equal to that of the bottom of the silicon rod. By the design, by utilizing hard resin strips which are as long as the silicon rod, have widths of 15 MM and thicknesses of 2 MM, and are attached on the left corner and the right corner of the knife entering position of the silicon rod, the silicon rod workpiece of the multi-wire cutting machine cuts a wire mesh into the resin strips with relatively softer textures first, decreases the shake of a steel wire, reduces the non-uniformity of the slice thickness of a silicon slice, and increases the rate of finished products of the silicon slice.
Description
Technical field
The utility model relates to the field of the cutting machine of multi-thread cutting monocrystalline, polycrystalline silicon rod.
Background technology
Elevating mechanism and two home rolls are set in the multi-line cutting machine, and the below of elevating mechanism connects the silicon rod workpiece, and the periphery of every home roll spiral respectively is provided with groove, same steel wire of coiling in the groove of two home rolls, and steel wire is arranged on the below of silicon rod workpiece.Carry out silicon rod when cutting, the rotation of two home rolls drives steel wire and moves back and forth, and elevating mechanism drives the silicon rod workpiece and moves down, and cuts into some silicon chips through the cooperation realization of steel wire and slip is multi-thread.Gauze runs up and causes the steel wire shake during silicon rod feed, and silicon rod directly contacts the gauze of shake, causes the silicon chip feed to go out edge became uneven and wire jumper phenomenon.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, provide a kind of make the silicon chip thickness evenly, the silicon rod workpiece of the multi-line cutting machine that improves the quality of products.
The purpose of the utility model is achieved in that the silicon rod workpiece of multi-line cutting machine; Comprise silicon rod; Two resin streaks are pasted in the bottom of said silicon rod, and two resin streaks are separately positioned on the both sides of silicon rod width, and the length of every resin streak is the equal in length bottom silicon rod respectively.
The utility model is through above design, and utilization is long together with silicon rod, wide 15MM; Thick 2MM hard resin bar on the left and right corner of subsides and silicon rod feed place, lets gauze cut quality softer resin streak relatively earlier; Reduce the steel wire shake, it is even to reduce silicon chip sheet thickness ununiformity, increases the silicon chip yield rate.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the silicon rod workpiece for multi-line cutting machine comprises silicon rod 1, and the both sides that 2, two resin streaks 2 of two resin streaks are separately positioned on silicon rod 1 width are pasted in the bottom of silicon rod 1, the length of every resin streak 2 respectively with the equal in length of silicon rod 1 bottom.
Claims (1)
1. the silicon rod workpiece of multi-line cutting machine comprises silicon rod, it is characterized in that: two resin streaks are pasted in the bottom of said silicon rod, and two resin streaks are separately positioned on the both sides of silicon rod width, and the length of every resin streak is the equal in length bottom silicon rod respectively.
