Description
Technical field
The utility model relates to can prevent that the base of limit and error from appearring collapsing in silico briquette when minority carrier life time detects, and belongs to the photovoltaic field, is mainly used in supporting the use of minority carrier lifetime tester device.
Background technology
At present minority carrier lifetime tester silico briquette display unit with being in contact with one another in the process of silico briquette, be easy to cause silico briquette to collapse the limit equivalent damage.Collapse the limit part owing to the quality requirements that can't reach production is cut off, can't enter next process, thereby cause the reduction of silicon material effective rate of utilization, caused very large waste.
Simultaneously, when detecting machine seek the location, limit, the single-point on silico briquette upper surface four limits is as the border.If silico briquette is when placing, the edge is parallel with monitor station, and the silico briquette after then locating is shaped as trapezoidal, and silico briquette has the subregion to test, and affects test result.Because silico briquette is heavier, the testing staff places the several method of silico briquette when few son detects: one, first the silico briquette afterbody is placed on the monitor station, and head is extracted out during to the proximity test table top fast slowly placing under hand steered effect above the monitor station; Two, it is one-sided first the silico briquette afterbody to be placed on monitor station, and in the outside of monitor station, the mobile silico briquette of then exerting oneself makes it the complete monitor station middle part that is placed into to head when slowly putting down under hand steered effect; Three, the personnel that strength is larger are parallel to be taken silico briquette in one's arms and is placed into gently monitor station and then adjusts.Place the result and have two kinds: one, the testing staff is parallel with the monitor station edge by the long limit of silico briquette adjust silico briquette with reference to the position at table top limit, angle after; Two, the direct placement of testing staff is not adjusted or adjustment does not put in place and make the silico briquette edge and monitor station edge not parallel (this kind result causes the line error easily).When silico briquette is placed, if collapse the limit for method one very easily causes when there is white residue in hard or table top at table top, and in the method since the time single head place afterbody and withstand shocks heavierly, cause that very easily the bottom adjacency falls slag and affects lower piece test; Method two better but will carefully adjust occurs easily adjusting not in place and causes the line error; Three strength that need the testing staff that one ingot is arranged of method, the problem of appearance in the method one also can appear in the while owing to physical demands is excessive when task is nervous.Placing the result is for the moment better, if test error can occur after detecting when being result two, thereby causes the line error.Elapsed time is more when adjusting the position, thereby lowers efficiency.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, provide and to prevent that the base of limit and error from appearring collapsing in silico briquette when minority carrier life time detects, this base reduces silico briquette and display unit contact area, reduces the probability that broken silicon material stops at monitor station; Reserve the room at the silico briquette two ends, make things convenient for and put the rational placement location of Shi Shouyou as the silico briquette; Lay layer of material in display unit, protection directly contacts with the metal detection platform when avoiding the silico briquette minority carrier lifetime at the outside surface of metal detection platform, and the minimizing people is for collapsing the surface damage such as limit; Increase a rapid adjustment and place the device of shape.
The purpose of this utility model is achieved through the following technical solutions: can prevent that the base of limit and error from appearring collapsing in silico briquette when minority carrier life time detects, comprise monitor station, described monitor station upper surface indent forms groove, and the two ends of groove are communicated with the sidewall of monitor station, are provided with protective seam on the monitor station; Be provided with adjusting gear on the sidewall of described monitor station away from groove.
Further, the section of described adjusting gear is L-type, and this adjusting gear one end is connected with the sidewall of monitor station, be provided with beam on the end face of the other end, be provided with protective layer between adjusting gear and the monitor station, protective layer is fitted on the sidewall of adjusting gear, and the top of protective layer contacts with the bottom of beam.The structure of adjusting gear can be various ways, and the side need to keep with monitor station in the same level face.
Further, described groove is divided into the surface of contact of two symmetries with the end face of monitor station, and protective seam is fitted on this surface of contact.The contact area that minimizing monitor station and silico briquette are set of groove.
Further, the bottom surface of the bottom surface of described monitor station and adjusting gear is in the same level face.Adjusting gear carries out the rapid adjustment silico briquette and places shape as backrest.
Further, described monitor station and adjusting gear all adopt stainless steel material to make; Described protective seam and protective layer all adopt High molecular weight polyethylene to make; Described beam adopts rubber to make.Detecting table top increases protective material, directly contacting with the metal detection platform when reducing test, and the minimizing people is for collapsing the surface damage such as limit.
In sum, the beneficial effects of the utility model are:
(1), reduces the silico briquette that lacks sub-detection platform and collapse the limit;
(2), reducing silico briquette places the unreasonable of result, the error thereby minimizing is rule;
(3), regulating the speed after improving silico briquette and placing, improve detection efficiency.
