[technical field]
The invention belongs to cutting silicon single crystal rod field, especially belong to a kind of and use with the multi-line cutting machine coupling, be used for fixing silicon single crystal rod, auxiliary multi-line cutting machine cuts into silicon single crystal rod in the device of silicon single crystal flake.
[background technology]
When adopting multi-thread cutting silicon single crystal rod to obtain silicon single crystal flake technology, multi-line cutting machine needs by the fixing servicing unit of silicon single crystal rod.Described device is made of an adhesive strip and an adhesive sheet, and adhesive strip is a surface plate that nonmetallic materials are made, and plane is used for the bonding single crystal silicon rod on it, and the baseplane sticks with glue to connect and is fixed on the adhesive sheet.Adhesive sheet is fastened on the workbench of cutting machine, realizes the cutting location of silicon single crystal rod.There are the following problems in practice for this device: the connecting mode of adhesive strip and adhesive sheet adopts colloid bonding, and the efficient that not only wastes time and energy is low, the consumables cost height, and also also there is a high temperature degumming operation in the adhesive sheet that uses repeatedly as need.And in the high temperature degumming process, easily cause adhesive sheet to be out of shape, therefore, in the follow-up use of adhesive sheet, at itself and multi-line cutting machine platform fixedly the time, be easy to cause the adhesive strip that has been bonded on the adhesive sheet come unstuck, damaged, come off, even excellent phenomenon appears falling in cutting process, and seriously jeopardize silicon single crystal rod safety, operating irregularity takes place.
[summary of the invention]
The technical problem to be solved in the present invention provides a kind of fixture of auxiliary multi-line cutting machine cutting silicon single crystal rod, utilize the auxiliary cutting machine of this device that silicon single crystal rod is carried out cutting operation, have time saving and energy saving efficient height, cost is low, and adhesive sheet do not need high temperature to remove the characteristics of glue, in cutting process, can not occur adhesive strip come unstuck, damaged, come off and fall excellent phenomenon.
The technical scheme that addresses the above problem is as follows: the fixture of this auxiliary multi-line cutting machine cutting silicon single crystal rod, comprise an adhesive sheet and an adhesive strip, described adhesive strip is positioned at the upper surface of described adhesive sheet, it is characterized in that: also have a locking strip in this device, the upper surface of described adhesive sheet has a Baltimore groove of admitting described adhesive strip and locking strip, and the two side of described adhesive strip is uneven the connection with described Baltimore groove and the corresponding sidewall of locking strip; Described locking strip is in the fastening bolt detachable is fixed on described Baltimore groove.
During concrete enforcement, the bottom surface of described locking strip has the holder of admitting described fastening bolt; On the diapire of described adhesive sheet Baltimore groove corresponding to locking strip, has the through hole that several admit described holder, the cross sectional shape of this through hole is " protruding " font, fastening bolt is locked at locking strip on the adhesive sheet from the bottom up, and the afterbody of fastening bolt sinks in the through hole of described " protruding " font.
During concrete enforcement, on the spill cell wall of the described Baltimore groove of the free sidewall of locking strip relatively, be provided with some tapped through holes and fastening bolt thereof, the free sidewall of the end of described fastening bolt and locking strip offsets.
Compared with prior art, the present invention adopts uneven structure, and locking strip connects adhesive strip and adhesive sheet, thoroughly changed the situation that prior art adopts bonding way to connect, assembling is simple, connection is firm, after particularly omitting bonding, high temperature and removing the glue two procedures, not only solved the adhesive sheet problem on deformation, reduced and used the glue cost, in cutting process, can not occur adhesive strip come unstuck, damaged, come off and fall excellent phenomenon, and, also reduced specification requirement to operating personnel, very help the raising of product quality.After measured, after existing multi-line cutting machine adopts this device, can effectively reduce the cutting blemishes (bright spot) of silicon single crystal flake, make the finished product rate improve 1-2 percentage point.

Among the figure: adhesive sheet 10, fastening bolt 101, adhesive sheet bottom surface 102, through hole 103 connects counterbore 104, spill cell wall 105, tapped through hole 106.Adhesive strip 20, end face 201, curved end 2011, dovetail groove 202, adhesive strip bottom surface 203, dovetail inclined-plane 204.Locking strip 30, fastening seat 301, bolt hole 3011, inclined-plane 302.Fastening bolt 40, bowl-type pad 41.
[specific embodiment]
Referring to Fig. 1.This device is made of adhesive sheet 10, adhesive strip 20 and locking strip 30 3 parts.Adhesive sheet 10 is that a bottom surface is the plane, and end face has the rectangular slab of Baltimore groove.In the two side of described Baltimore groove, right side wall is the dovetail wall, and left side wall is a right angle walls.Relative locking strip 30 vertically is the through hole 103 of " protruding " font to having cross sectional shape, and level is to having the tapped through hole 106 of admitting fastening bolt 101.
In conjunction with Fig. 2.Adhesive strip 20 is the rectangular slab that end face, a bottom surface are the plane, and plate body bottom shape has dovetail groove 202, and its dovetail inclined-plane 204 is downward.
In conjunction with Fig. 3.The length of locking strip 30 is consistent with adhesive strip 20, and sidewall is provided with the inclined-plane that the dovetail inclined-plane 204 with adhesive strip 20 is complementary.On its bottom surface, be provided with the fastening seat 301 of one, on fastening seat 301, be provided with downward bolt hole 3011.The quantity of fastening seat 301 can depend on the circumstances.
In conjunction with Fig. 4.During assembling, adhesive sheet 10 places the bottom, again adhesive strip 20, locking strip 30 is put into the Baltimore groove of adhesive sheet 10 end faces, and makes adhesive sheet 10, adhesive strip 20 and locking strip 30 corresponding sidewalls be adjacent to engagement mutually.At this moment, the fastening seat 301 on the locking strip 30 just in time drops in the through hole 103 that adhesive sheet 10 cross sectional shapes are " protruding " font.Then, with fastening bolt 40, and be encased inside bowl-type pad 41 and be fixed on from bottom to up on the bolt hole 3011, locking strip 30 is fixed on the adhesive sheet 10.Level screws in to the tapped through hole 106 of the bolt that is provided with on spill cell wall 105, utilizes the bolt end that locking strip 30 is withstood, and reaches the purpose that further fixedly positioning adhesive strip 20.
Figure 5 shows that the adhesive strip structure of another embodiment, the difference of this adhesive strip structure and aforementioned adhesive strip only is that its end face is a curved end 2011, and the end face of aforementioned adhesive strip 20 is the plane.The variation of this structure mainly is to consider and the workpiece problem that matches that is: the silicon single crystal bar cross sectional shape of solar energy and device is respectively square and circular, like this between bonding.
During use, earlier silicon single crystal bar is sticked with glue the upper surface that is connected on adhesive strip 20, by above-mentioned adhesive strip 20 is fixed on the adhesive sheet 10 then.At last, the connection counterbore 104 through adhesive sheet 10 bottom surfaces is fixed on whole device on the workbench of multi-line cutting machine, can carry out cutting operation.
