Description
Technical field:
The utility model relates to a kind of silicon rod butt machine, relates in particular to the silicon rod positioning clamping device 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 use the butt machine that the silicon rod section is cut into the square of cross sectional shape for the band fillet, 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 after heating, presses and stick together; Be placed on four such silicon single crystal rods by excellent central vertical in the positioning spigot of equipment by the location minor axis, the positioning spigot in the equipment is arranged by square position, and bands for band cuts from the top down; Integral body is revolved and is turn 90 degrees after cutting four times; Cutting is cut four times from top to bottom successively again, needs cutting to accomplish the cutting processing of four silicon rods for eight times altogether, is placed on the combination of every silicon single crystal rod with the location minor axis in the container of heating after cutting is accomplished; 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, after adjusting, proofread and correct through center again, hold out against clamping again the silicon single crystal rod both ends of the surface; Cutting processing after the cutting of article one limit finishes, is carried out length feed and is cut the second limit more then; 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, could accomplish the butt of silicon single crystal rod through two cutting machines.These two kinds of silicon rod butting techniques all exist deficiency in actual process, first kind of process need be glued together silicon single crystal rod; After machining, also need add thermosol, the operation process is very complicated, and 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; Being easy to cause silicon rod in the butt process, to produce scraps; The shortcoming of this butting technique is: silicon rod is accomplished butt processing to be needed through the secondary clamping, and clamping must rely on manual work that silicon single crystal rod is proofreaied and correct at every turn, operates cumbersome; Debugging efficiency is very low, is easy to generate butt and scraps.
In order to overcome the above-mentioned deficiency that existing silicon rod butt machine exists, the applicant has developed the silicon rod butt machine that a kind of self-centering clamps synchronously, and it can eliminate the influence to butt processing of silicon rod cylindricity, circularity and rough surface; Apace silicon rod is positioned clamping; Whole butt process, silicon rod is as long as once clamp the cutting processing that just can accomplish 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.In this butt machine, the self-centering synchronous clamping device is crucial.
The utility model content
The purpose of the utility model is for the butt machine a kind of silicon rod self-centering synchronous clamping device to be provided.
The technical scheme that the utility model adopted is:
A kind of silicon rod self-centering synchronous clamping device; Is made up of two self-centering locating clip clamping units that distribute along butt machine direction of feed conllinear, each self-centering locating clip clamping unit group comprises mobile guide seat, clamping cylinder, goes up the grip slipper slide plate, grip slipper slide block, gear, V-block and last V-block down down, be provided with on the mobile guide seat horizontal sliding groove, on vertical guided way and following vertical guided way; The mobile guide seat is sleeved on vertical feeding slide unit through the horizontal sliding groove; Hypomere at last grip slipper slide plate lower outside face is provided with tooth bar limit A, is provided with upper ear seat in the upper end of last grip slipper slide plate, and last grip slipper slide plate is sleeved on the last vertical guided way of mobile guide seat; Following grip slipper slide block set is contained on the following vertical guided way of mobile guide seat; Be provided with lower ear base and tooth bar limit B on the grip slipper slide block down, gear is installed on the mobile guide seat, and the axis of gear is parallel with the direction of horizontal sliding groove; Gear is between tooth bar limit A and tooth bar limit B; And tooth bar limit A and tooth bar limit B are equal and gears engaged, and following V-block is installed in down on the lower ear base of grip slipper slide block, and last V-block is installed on the upper ear seat of grip slipper slide plate; And the line of symmetry of the V-arrangement bearing-surface of following V-block and last V-block is on the same straight line, and both are symmetrically distributed; The cylinder body of clamping cylinder is fixed on the mobile guide seat, and the piston rod of clamping cylinder is fixedly connected with last grip slipper slide plate, and piston rod is parallel with the glide direction of last grip slipper slide plate.
Further, said V-block down and last V-block are free to rotate in horizontal plane.
Further, motor is a servomotor in the said electronic indexing means.
It is that the silicon rod section is accurately located and clamped in advance that the utility model acts in the butt machine, for the final clamping of jack unit provides accurate location, before cutting; Earlier silicon rod is carried out the self-centering location and clamps in advance synchronously, make the axis of silicon rod to be cut parallel with direction of feed all the time, and then finally clamp by two end faces that jack unit is aimed at silicon rod to be cut by two in the utility model double V-shaped; Make silicon rod to be cut be in accurate location clamped condition; Again the self-centering clamping device is unclamped, carry out successively then that vertical feeding, cutting, rewind down reset, silicon rod rotation calibration, cut second again, so circulation; After silicon rod all cuts end; Feeding slide unit rewind down resets, and can take out the silicon rod of butt, accomplishes whole silicon rod cutting work.This self-centering clamping device relies on two synchronous tightening systems of V-block that silicon rod is positioned and clamps in advance; Even silicon rod exists cylindricity, deviation from circular from, the not high defective of silicon rod surface quality, it can both be with the axial line control of silicon rod on same position; And it is vertical with two end faces that cut; Both non cohesive gel in the whole clamping process of silicon rod, also positioning and clamping repeatedly not is as long as clamping can be accomplished four limit cutting processing of silicon rod; The dimensional accuracy of processing and the accuracy of form and position are all high than prior art, and working (machining) efficiency can improve 25%～30% simultaneously.
