Description
Technical field
the present invention relates to photovoltaic cell component product and manufacture field, relate in particular to a kind of battery component EL test Portable clamp.
Background technology
EL(electroluminescence, electroluminescence) test refers to according to the difference of photovoltaic cell component luminosity and clearly illustrates sliver in assembly (comprise hidden split and show split), bad and weld defect, can improve rate of finished products for test before lamination, increase power output, can stop problem component for final test and come into the market, and can be by reprocessing to make up rate of finished products.
When photovoltaic cell component carries out EL test, first open the door of EL tester, photovoltaic cell component is transported on the testboard of tester, then manually the both positive and negative polarity wire harness of the terminal box on battery component is connected respectively with the both positive and negative polarity wire harness of EL tester, now the door of tester is in open mode.After battery component is applied to voltage, make it luminous, recycling infrared video camera is collected its luminous image, and because electroluminescence brightness is proportional to minority diffusion length, fault location sends weak light because having less minority diffusion length, thereby forms darker image.
Can cause test period longer but manually carry out wire harness connector, and while connecting connector under door opening state, be prone to exposure image, need to retest.
Summary of the invention
the technical problem to be solved in the present invention is to provide a kind of battery component EL test Portable clamp that can shorten test period, avoid image exposure.
For solving the problems of the technologies described above, the present invention relates to a kind of battery component EL test Portable clamp, comprise the first clamping plate and second clamping plate of stacked on top of one another, between described the first clamping plate and the second clamping plate, leave space, described the first clamping plate arrange two grooves on the surface of described the second clamping plate dorsad, and the bottom of described groove arranges Metal Contact sheet; Described Metal Contact sheet is connected with the both positive and negative polarity of described battery component by wire harness connector.
Preferably, on described the first clamping plate and the second clamping plate, be equipped with screw, the pore size between the first clamping plate and the second clamping plate regulates by the degree of tightness of bolt and nut.
Preferably, described battery component comprises edge frame made of aluminum profiles, and described fixture is fixed on the edge frame made of aluminum profiles of described battery component, and described edge frame made of aluminum profiles embeds the space between the first clamping plate and the second clamping plate, and is fixedly clamped by bolt and nut.
Preferably, described battery component comprises terminal box, and anode interface and negative pole interface are set in described terminal box.
Preferably, described wire harness connector comprises wire, positive terminal and anode connector.
Preferably, the positive terminal of described wire harness connector is connected with the anode interface of described terminal box, and the anode connector of described wire harness connector is connected with the negative pole interface of described terminal box.Now Metal Contact sheet is just equivalent to the both positive and negative polarity of battery component.
Preferably, the thickness of described the first clamping plate is greater than the thickness of described the second clamping plate.The degree of depth of the first clamping plate groove is less than or equal to the thickness difference between the first clamping plate and the second clamping plate, thereby guarantees that two laminated planks have enough intensity can not rupture in the time being fixedly clamped.
Using method and the beneficial effect of this fixture are as follows: before battery component enters EL tester, battery component EL test is snapped on the fixed position of battery component edge frame made of aluminum profiles with Portable clamp, by bolt and nut, the one the second clamping plate are fixed.In two grooves of the first clamping plate, place respectively Metal Contact sheet, Metal Contact sheet is connected with the both positive and negative polarity of battery component junction box by wire harness connector respectively, and now Metal Contact sheet is just equivalent to the both positive and negative polarity of battery component.Assembly enters after EL tester automatically, and the metal probe of tester contacts with the Metal Contact sheet of fixture, reaches the object of automatic test, effectively shortens test period 3S, and makes the probability that occurs exposure image reduce to 0 by 20%, and avoiding doing over again retests.
