Description
Technical field:
The present invention relates to the pick-up unit of solar battery sheet, relate in particular to the electric property detection device of solar battery sheet.
Background technology:
In the production run of solar module, must carry out total electrical property to the battery sheet detects, and divide into groups, the battery sheet that will have similar characteristic is together in series and encapsulates and could obtain people's predetermined battery assembly, makes the predetermined voltage of solar module output.According to designing requirement, the battery sheet in same solar module should show identical characteristic, and the I-V curve of whole assembly and single battery sheet should have similar shapes, just the yardstick of coordinate axis difference to some extent.Therefore before battery sheet series welding, must detect classification earlier totally, how rapidly and accurately the battery sheet being carried out that electrical property detects is an important job, it not only directly has influence on the final performance index of battery component, and directly has influence on detection efficiency.At present, the industry adopts solar battery sheet I-V ability meter to detect usually, described solar battery sheet I-V ability meter comprises battery sheet I-V curve display instrument 1, monitor station 2 and slide glass plate 3, in monitor station 2, be provided with flexible gauge head, flexible gauge head is by metal probe 4, insulcrete 5 and expansion link 6 are formed, fix an insulcrete 5 in the lower end of expansion link 6, the fixing metal probe 4 of two rows is installed on insulcrete 5, every row's metal probe 4 coupled together draw with lead respectively, receive on the battery sheet I-V curve display instrument 1, during detection, as long as two on the insulcrete 5 row metal probe 4 is contacted with both positive and negative polarity on the battery sheet 7 to be checked respectively.In testing process, require the lower surface of all metal probes 4 to contact with the positive and negative of battery sheet 7 to be checked simultaneously, otherwise will influence testing result, therefore, action wants light and handy when operation, can not be firmly excessive, in case the battery sheet is damaged by pressure, again can not be firmly too small, prevent that the electrode virtual connection of metal probe and battery sheet from touching, thereby influence classification quality.Because existing metal probe is a rigidity, occurs the battery sheet often and crushed or detect inaccurate defective in the actual detected process.The applicant is by thinking that these defectives all are because unreasonable the causing of structural design of metal probe.Guarantee to detect accurately, the bottom of all metal probes is reliably contacted with the electrode band of battery sheet, this just requires the lower surface of all metal probes necessary in the same plane, reaching this requirement is difficult to, should improve the machining precision of mounting hole on the machining precision of metal probe and the insulcrete, and to improve both installation accuracies, if do not reach requirement, in metal probe and battery plate electrode band contact process, certainly existing metal probe can not contact with the electrode band of battery sheet simultaneously, will cause detecting inaccurate like this, all metal probes are all contacted with the electrode band of battery sheet must increase pressure, the battery sheet can be crushed so again.This structure, even the lower surface of all metal probes all can be in the same plane when mounted, can not guarantee the accuracy of testing result, because in use not only metal probe can produce loosening, and the thickness of the electrode band on every battery sheet is also variant, the same like this accuracy that can not guarantee each testing result.
Summary of the invention:
The purpose of this invention is to provide a kind of battery sheet electrical property device for fast detecting, all metal probes can both contact with battery sheet top electrode band when it can guarantee to detect at every turn, and can guarantee that pressure is even, prevented that the battery sheet from being damaged by pressure, both improve the accuracy that detects, improved detection speed again.
The technical solution adopted in the present invention is:
A kind of battery sheet electrical property device for fast detecting, comprise battery sheet I-V curve display instrument, monitor station and slide glass plate, in monitor station, be provided with metal probe, insulcrete and expansion link, all metal probes all are fixedly mounted on the lower surface of insulcrete, insulcrete is fixedly mounted on the lower end of expansion link, expansion link monitor station relatively vertically slides up and down, the slide glass plate is fixed on the base of monitor station, metal probe is electrically connected with battery sheet I-V curve display instrument, it is characterized in that: described metal probe is by needle guard, spring and flexible shank are formed, described needle guard is the multidiameter nested structure, it is by the top flange, spring eye, last cover body, the lower limit step, the pilot hole and the body of trapping are formed, spring eye is positioned at the top of pilot hole, spring eye and pilot hole are coaxial aperture system, and spring eye cooperates with the crest clearance of spring, and the aperture of pilot hole is littler 0.3～0.6 millimeter than the aperture of spring eye; Flexible shank is made up of spring shaft, guide pole and contact feet, spring shaft is arranged on the upper end of guide pole, contact feet is arranged on the lower end of guide pole, the external diameter of guide pole is littler 0.3～0.6 millimeter than the external diameter of spring shaft, and spring housing is contained in the spring eye of needle guard, and the spring shaft of flexible shank is sleeved in the spring eye of needle guard, and be positioned at the lower end of spring, spring shaft and spring eye clearance fit, the guide pole of flexible shank is located in the pilot hole of needle guard guide pole and pilot hole clearance fit.
Because the monitor station in the existing solar battery sheet I-V ability meter is improved, change metal probe into concertina type by original fixed, the flexible metal probe is fixed on the lower surface of insulcrete by needle guard, the slide glass plate is fixed on the base of monitor station, battery sheet to be checked lies on the slide glass plate, during detection, as long as expansion link is moved down into extreme position, at this moment, the insulcrete and the metal probe that are fixed on the expansion link lower end just move down synchronously, the contact feet of metal probe has all contacted with electrode band on the battery sheet to be checked, just the flexible shank stroke in the different metal probe has micro-difference, because contact feet is controlled by spring the contact pressure of battery sheet, therefore, even have micro-drop, can guarantee that also the contact feet of flexible shank all contacts with electrode band with the lower end of the every metal probe of arranging, and can make contact pressure approaching, can prevent effectively that the battery sheet from being crushed.All metal probes can both contact with the electrode on the battery sheet when it can guarantee to detect at every turn, can prevent crushing battery sheet again, had improved the accuracy and the detection efficiency that detect.
