Description

Compression clamp for solar battery attenuation test

Technical field

The present invention relates to solar cell test device, relate in particular to the exposing frame for use in attenuation test of solar battery device.

Background technology

In recent years, solar cell is as a kind of novel energy of clean environment firendly, obtain applying more and more widely, be the key technical indexes of weighing battery quality the useful life of solar cell, just refers to theoretically the size of solar cell attenuation the useful life of solar cell.In actual production process, people adopt outdoor formula illumination method of testing to test it conventionally, cell piece is directly placed in outdoor, utilize natural sunlight to irradiate solar cell, relatively check and rate its attenuation by the watt level that solar cell to be detected was exported according to the period before and after shining, with this outdoor formula illumination method of testing, the natural daylight that solar cell receives is very unstable, intensity of illumination, light application time all changes with natural weather, people are uncontrollable, not only, the cycle of test is very long, and the test data of gained cannot repeat, confidence level is poor, cell piece is placed in the outdoor protection that also can not get simultaneously, easily be blown over by the wind and break.At present, in manufacture of solar cells industry, although it is the key technical indexes of weighing solar cell quality that people know useful life, but owing to lacking concrete testing standard, more there is no the checkout equipment of public letter, because user extremely values this index, manufacturing enterprise only promises to undertake and can reach 20 years to user, but do not have corresponding test data to prove its useful life.

In order to meet better user's requirement, applicant has developed a kind of solar cell testing equipment in useful life, solar battery sheet to be detected is decayed with the illumination through 60 hours under specified temp environmental condition of particular light intensity, and measure initiating terminal and the electrical quantity of the end of ending, calculate thus the decay indices of solar cell, adopt this analog light source to irradiate method of testing, as long as carry out indoor, and intensity of illumination is stable, the attenuation test time is controlled, efficiency is high, gained test data is reproducible, with a high credibility, simultaneously, in test process, cell piece can not damage.In this testing equipment, analog light source irradiation unit, exposing frame for use in are all key devices, and compression clamp is the vitals in exposing frame for use in.

Summary of the invention

The object of this invention is to provide a kind of compression clamp for solar battery attenuation test.

A kind of compression clamp for solar battery attenuation test, formed by left-hand rotation arm, right-hand rotation arm, bearing pin, support, stage clip and elastic tightening cover, the epimere of left-hand rotation arm is that straight-bar handle, stage casing are that obliquity rod, hypomere are compressing tablet, is provided with conductive contact in the lower end of compressing tablet, is provided with pin-and-hole on obliquity rod, the planform of right-hand rotation arm and left-hand rotation arm symmetry, bearing pin is fixed on support, left-hand rotation arm and right-hand rotation arm are sleeved on bearing pin symmetrically by pin-and-hole, support is fixed on exposing frame for use in by screw, support can rotate with respect to screw, stage clip is arranged between the straight-bar handle of left-hand rotation arm and the straight-bar handle of right-hand rotation arm, elastic tightening is set between the straight-bar handle of left-hand rotation arm and the straight-bar handle top of right-hand rotation arm, under detected state, the anodal grid line of cell piece is placed on the metal hook of exposing frame for use in, conductive contact on left-hand rotation arm is pressed on the negative pole grid line of cell piece, on conductive contact, be connected to output lead, equally, conductive contact on right-hand rotation arm is pressed on the negative pole grid line of adjacent cell sheet, on conductive contact on right-hand rotation arm, be also connected to output lead.

When test cell piece must stably leave on exposing frame for use in grid, to from the anodal grid line of cell piece and negative pole grid line, be drawn by wire simultaneously, be convenient to and being connected of signal of telecommunication collecting circuit, thereby measure open circuit voltage and the short circuit current of cell piece, because the anodal grid line of cell piece is just in time put down on the metal hook of putting on exposing frame for use in, and be connected to output lead on metal hook, according to the reasonable force request of cell piece, the conductive contact that is connected to wire must be pushed down negative pole grid line, be that every cell piece has the conductive contact on hook and the compression clamp on exposing frame for use in to come spacing and fixing, both spacing clamping elements of conductive contact on metal hook and compression clamp, it is again the lead-out terminal of the signal of telecommunication.Simultaneously, compression clamp must be fixed on exposing frame for use in, in cell slice test process, conductive contact on compression clamp must be pushed down the negative pole grid line of cell piece, in the time that test finishes, conductive contact on compression clamp must depart from cell piece fast and easily, being convenient to cell piece takes out and is reentered into, prevent the breakage of cell piece, in the present invention, compression clamp is designed to double-vane structure, a compression clamp clamping two adjacent cell pieces simultaneously, compact conformation, support is rotatably mounted on exposing frame for use in by screw, compressing tablet on left-hand rotation arm and right-hand rotation arm can depart from fast cell piece in the time of fetching battery sheet.
