The silicon rod butting machine comprises a feeding slipway seat, a feed motor, a feed slipway, a longitudinal feeding slipway, a longitudinal feeding motor, a jacking device, a self-centering double-supporting positioning clamping device, a vertical rack with a saw side, a saw blade, a hydraulic station and an electric control tank, wherein the self-centering double-supporting positioning clamping device can be used for self-centering, positioning and clamping a silicon rod to be cut so that axial lines of all silicon rods to be cut are on the same axial line, and two end faces of each silicon rod to be cut are vertical to the axial line; the jacking device can guarantee that the silicon rods to be cut are reliably clamped in a jacking state so that the silicon rods to be cut are always in an accurate positioned and clamped state in the processing procedure; since the silicon rod section is positioned and clamped in two steps, the silicon rods are not only free from sticking, but also free from a plurality of times of positioning and clamping in the whole cutting processing procedure; four sides of the silicon rods can be cut by only clamping once, the processed size precision and shape precision is higher than those of the prior art, and the processing efficiency can be improved by 25-30%.
Description
Technical field:
The present invention relates to the silicon rod process equipment, relate in particular to a kind of silicon rod butt machine.
Background technology:
In the production process of solar module, the silicon rod of crystal pulling Workshop Production is processed into silicon chip must be successively through excision two ends bull, segment, butt and slicing process, after silicon rod cuts into the silicon rod section, must the silicon rod section be cut into the square that cross sectional shape is the band fillet with the butt machine, be commonly called as butt.At present, silicon rod butt machine mainly contains two kinds by the cutting tool branch, and first kind is the band saw blades cutting machine, and another kind is the saw disc cutting machine.The band saw blades cutting machine is before cutting processing, one end that at first will cut off the back silicon single crystal rod is coated with gluing with the location minor axis and presses after heating and stick together, be placed on four such silicon single crystal rods in the positioning spigot of equipment by excellent central vertical by the location minor axis, positioning spigot in the equipment is arranged by square position, bands for band cuts from the top down, integral body is revolved and is turn 90 degrees after cutting four times, cutting is cut 4 times from top to bottom successively again, need cutting to finish the cutting processing of four silicon rods for eight times altogether, after cutting is finished the combination of every silicon single crystal rod with the location minor axis is placed in the container of heating, the taking-up silicon single crystal rod changes next procedure over to after treating peptizationization, is used for cutting next time after the location minor axis cleans.When carrying out the silicon rod cutting with the saw disc cutting machine, need carry out cutting processing four times to silicon single crystal rod equally, the Double End that adopts jack unit to withstand silicon single crystal rod positions clamping, earlier silicon single crystal rod is clamped in advance, adjust by center again the silicon single crystal rod both ends of the surface, after the correction, hold out against clamping again, cutting processing then, article one, after the limit cutting finishes, carry out length feed and cut the second limit again, take off the silicon rod that has cut both sides then, position with existing plane, correction silicon rod end face makes it saw disc one Xian with next bench saw dish cutting machine, carries out the cutting on two limits in addition, every silicon rod need be installed secondary, just can finish the butt of silicon single crystal rod through two cutting machines.These two kinds of silicon rod butting techniques, in actual process, all exist deficiency, first kind of process need be glued together silicon single crystal rod, after machining, also need to add thermosol, the operation process is very complicated, cutting machine need be equipped with need servicing units such as indexing mechanism, cutting efficiency is very low, simultaneously, can't eliminate because of the outer circularity of silicon single crystal rod poor, adding that rough surface is irregular causes silicon rod end face and silicon rod central axis off plumb defective after the Qian Dao section of cutting operation, because in butting technique, the location minor axis glues together with the silicon single crystal rod end face, is easy to cause silicon rod to produce in the butt process and scraps, and the shortcoming of this butting technique is: silicon rod is finished butt processing to be needed through the secondary clamping, and each clamping must rely on manually to be proofreaied and correct silicon single crystal rod, operate cumbersomely, debugging efficiency is very low, is easy to generate butt and scraps.
Summary of the invention
In order to overcome existing silicon rod butt machine above shortcomings, the invention provides the silicon rod butt machine that a kind of self-centering clamps synchronously, it can overcome the influence to butt processing of cylindricity, circularity and the rough surface of silicon rod cylindrical, apace silicon rod is positioned clamping, whole butt process, silicon rod is as long as once clamp the cutting processing that just can finish four faces, and machining accuracy is reliable and stable, the silicon rod clamping is simple to operate, and is not high to operative employee's specification requirement.
