Description
(1) technical field
The present invention relates to after a kind of polycrystalline minority carrier life time detects and to rule measurer.
(2) background technology
Solar energy polycrystalline silicon ingot casting is a kind of column crystal, the direction of growth of crystal vertically upward, direction of heat flow vertically downward, realized by directional solidification process, namely in the process of crystallization, by controlling thermal field change, form unidirectional hot-fluid, and require that mushy stage interface thermograde is greater than 0, and the plane of transverse direction is without thermograde, thus define the column crystal of directional solidification.Silicon ingot flaw-piece utilizes excavation machine to excise, silicon ingot end to end defective part then detects amputation according to minority carrier life time, evolution after silicon ingot is taken out in crucible, after evolution, silicon ingot is split into 5*5 totally 25 pieces of silico briquettes being of a size of 156*156, silico briquette after evolution need detect minority carrier life time, according to minority carrier lifetime result amputation defective part end to end.Therefore, need the disabled part of 25 build tail all to cut away.Existing operation is generally every silicon ingot test A district (9 pieces)/each one piece of B district (12 pieces)/C (4 pieces) district behind the side of taking away, according to defective region the amputation of ruling end to end of this block test result mark, with other silico briquettes in region decaptitate tail line decide according to test block, other silico briquette with region highly will be removed according to the removal of test block, then measure with ruler tail length of decaptitating, to make marks end to end line at other silico briquettes in same region highly again according to removal afterwards, then amputate successively.This method workload is large, and operation is wasted time and energy, and greatly reduces operating efficiency.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, provide a kind of rational in infrastructure, convenient and practical, simple to operate, time saving and energy saving, line accurately, workload little and the polycrystalline minority carrier life time that can increase work efficiency is rule after detecting measurer, solve problems of the prior art.
The present invention is achieved through the following technical solutions:
To rule after a kind of polycrystalline minority carrier life time detects measurer, comprise a wooden base, connect one to fit the rule arranged with wooden base in the front end of wooden base, be respectively equipped with a groove in the side of the wooden base front portion corresponding with rule upper/lower terminal, slide up and down respectively in groove and be provided with a square; One is respectively equipped with for the first trip bolt of fixing square at the two ends up and down on the corresponding each square base of wooden base rear portion.
Be respectively equipped with one second trip bolt at the corner place of rule, described rule is fixedly connected with by the second trip bolt with wooden pan frontward end.
Described rule is connected by binding agent is bonding with wooden pan frontward end.
The invention has the beneficial effects as follows: measurer of ruling after the detection of this polycrystalline minority carrier life time, rational in infrastructure, convenient and practical, simple to operate, accuracy of ruling in scratching process is high, intercepts same region even every the consistent size end to end of silico briquette, greatly saves to repeat to measure each domain test silico briquette height continuous mark on other silico briquettes are rule and the workload intercepted end to end, result is reliable and stable, ensure that silico briquette quality.Operator is required low in whole scratching process, time saving and energy saving, substantially increase the operating efficiency of line.Arranged by the rule of wooden pan frontward end and the anterior two ends up and down of wooden base groove and slide up and down the square design be arranged in groove, ensure that silico briquette test block has clearly measured while fast scribing end to end and remove height, because square position is fixed by the first trip bolt, line measurer state after polycrystalline minority carrier life time after making other silico briquettes of same region all use block line after tested detects, without the need to again regulating, very convenient, greatly reduce workload, improve operating efficiency.

(5) detailed description of the invention
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the present invention will be described in detail.
Embodiment 1
As illustrated in the accompanying drawings from 1 to 3, after this polycrystalline minority carrier life time detects, line measurer comprises a wooden base 1, connect one to fit the rule 2 arranged with wooden base 1 in the front end of wooden base 1, be respectively equipped with a groove 3 in the side of wooden base 1 front portion corresponding with rule 2 upper/lower terminal, slide up and down respectively in groove 3 and be provided with a square 4; At wooden base 1 rear portion, the two ends up and down on corresponding each square 4 base are respectively equipped with one and wear the first trip bolt 5 to the fixing square 4 in groove.
Be respectively equipped with one second trip bolt 6 at the corner place of rule 2, described rule 2 is fixedly connected with by the second trip bolt 5 with wooden base 1 front end.
Embodiment 2
As shown in accompanying drawing 4-5, be another embodiment of the present invention, after this brilliant minority carrier life time detects, line measurer and embodiment 1 difference are, being connected by binding agent 7 is bonding with wooden base 1 front end below of described rule 2.
Below for the silicon ingot after a certain evolution, illustrate that the embodiment of the present invention 1 and embodiment 2 polycrystalline minority carrier life time detect the using method of rear line measurer.Silicon ingot is split into 5*5 totally 25 pieces of silico briquettes being of a size of 156*156, position in silicon ingot residing for silico briquette is divided into A district (9 pieces)/B district (12 pieces)/C (4 pieces), choose each one piece of each district silico briquette and carry out minority carrier life time detection, according to each district silico briquette test result mark defective region end to end.The left side of the base right-justification silico briquette of line measurer after this polycrystalline minority carrier life time is detected, mark according to silico briquette defective region end to end moves up and down square respectively to mark, the height in the defective region of mark clearly can be understood in moving process, then the first trip bolt of manual base rear portion makes upper and lower two squares fix, rule respectively along square, according to line by silico briquette defective region amputation end to end.Take off after this polycrystalline minority carrier life time detects and to rule measurer, for the line of the silico briquette of same subregion, without the need to again regulating, after directly this polycrystalline minority carrier life time being detected line measurer after tested block regulate stationary state to be placed on the side of next silico briquette, then vertically rule in the chi limit of two squares, avoids and go to measure the intercepting size of test block again, measures again and rule, intercept according to intercepting dimensional height on next silico briquette, greatly reduce workman's workload, improve operating efficiency.In other regions, silico briquette is rule according to the method described above.
The present invention does not describe part in detail, is the known technology of those skilled in the art of the present technique.What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
