Abstract

The invention discloses a compression clamp for a solar battery attenuation test, which consists of a left rocker arm, a lift rocker arm, a pin shaft, a bracket, a compression spring and an elastic fastening sleeve, wherein the pin shaft is fixed on the bracket; the left and the right rocker arms are symmetrically sleeved on the pin shaft through pin holes; the bracket is fixed on an exposing bracket by screws; the bracket can rotate relative to the screws; the compression spring is arranged between a straight-lever handle of the left rocker arm and the straight-level handle of the right rocker arm; and the elastic fastening sleeve is arranged between the top of a straight-lever handle of the rocker arm and the top of the straight-level handle of the right rocker arm. The compression clamp is designed with a two-wing structure and one compression clamp can clamp two adjacent batteries, so that the whole structure is compact; the bracket is rotationally fixed on the exposing bracket by the screws; clamping plates on the left rocker arm and on the right rocker arm can quickly deviate from the battery when the battery is placed and taken out, so that the battery can be taken out and replaced conveniently; and thus, the battery is prevented from damages.

Description

Compression clamp for solar battery attenuation test

Technical field

The present invention relates to the solar cell test device, relate in particular to the exposing frame for use in the 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 application more and more widely, be the key technical indexes of weighing the battery quality serviceable life of solar cell, just is meant the size of solar cell damping capacity the serviceable life of solar cell theoretically.In actual production process; people adopt open-air formula illumination method of testing that it is tested usually; directly be placed in the battery sheet outdoor; utilize the sunshine of nature that solar cell is shone; relatively check and rate its damping capacity by the watt level that solar cell to be detected was exported according to the period before and after shining; with this open-air formula illumination method of testing; the natural light that solar cell received is very unstable; intensity of illumination; light application time all changes with natural weather; people are uncontrollable; the cycle of test is very long not only; and the test data of gained can't repeat; confidence level is poor, and the battery sheet is placed in the outdoor protection that also can not get simultaneously, is blown over by the wind easily and breaks.At present, in the manufacture of solar cells industry, though it is the key technical indexes of weighing the solar cell quality that people know serviceable life, but owing to lack concrete testing standard, the checkout equipment that does not more have public letter, because the user extremely values this index, manufacturing enterprise only promises to undertake to the user can reach 20 years its serviceable life, but does not have corresponding test data to prove.

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

Summary of the invention

The purpose 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, form 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 the support, left-hand rotation arm and right-hand rotation arm are sleeved on the bearing pin by pin-and-hole symmetrically, support by screw retention on exposing frame for use in, support can rotate with respect to screw, stage clip is arranged between the straight-bar handle of the straight-bar handle of left-hand rotation arm and right-hand rotation arm, elastic tightening is set between the straight-bar handle top of the straight-bar handle of left-hand rotation arm and right-hand rotation arm, under detected state, the anodal grid line of battery sheet is placed on the metal hook of exposing frame for use in, conductive contact on the left-hand rotation arm is pressed on the negative pole grid line of battery sheet, on conductive contact, be connected to output lead, equally, conductive contact on the right-hand rotation arm is pressed on the negative pole grid line of adjacent cell sheet, also is connected to output lead on the conductive contact on the right-hand rotation arm.

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