Description
Technical field
The present invention relates to the manufacture of solar cells technical field, more particularly, relate to a kind of EL test connecting apparatus.
Background technology
Solar cell needs to adopt EL tester (EL test, the abbreviation of English Electroluminescence, defect test after assembling is finished.The EL tester, solar module defects detection full-automatic testing instrument, utilize the electroluminescence principle of crystalline silicon, adopt the near-infrared image of high-resolution CCD camera picture shooting assembly, obtain and judge the defective of assembly) with the solar cell conducting solar cell is carried out the hidden test of splitting, whether reach technological requirement to test its quality of production.
In the prior art, the process that the EL tester is tested solar cell is all finished in the camera bellows the inside, the most direct method of testing is the arrangement personnel connect EL tester and tested solar cell in the camera bellows the inside wire, but the camera bellows the inside is very dark, should not operate, and the space is very little in the camera bellows, personnel inside can not move basically, simultaneously, the streamline drive apparatus safety coefficient of camera bellows the inside is not high yet, and personnel's personal safety can't be effectively guaranteed.Therefore, the EL test mode that present people generally adopt is: the lid to the terminal box on the solar cell improves, at this lid two copper sheets are installed, these two copper sheets have all carried out bending in lid edge, so that it all can be distributed on the lateral surface and medial surface of lid simultaneously.When needs carry out the EL test to solar cell, lid after this improvement is installed on the terminal box of solar cell to be tested, the copper sheet that is installed on the lid can contact with the conducting metal in the terminal box, thereby make copper sheet and solar cell conducting, then make lid together enter into the camera bellows that carries out the EL test with solar cell, the test thimble that is arranged on the EL tester at camera bellows top moves down under the promotion of cylinder and contacts with two copper sheets, then the EL tester imaging that powers on.
But, there is defective equally in above-mentioned test mode: because the restriction of the self structure of lid, copper sheet ratio disposed thereon is easier to be subjected to displacement, so that copper sheet can't with terminal box in conducting metal effectively contact or depart from the contact position of test thimble when moving down, thereby cause the EL tester can't with the effective conducting of tested solar cell, so that test crash, success ratio can only reach 90%; Because the terminal box model of installing on the different solar cells may be different, and through the lid of transformation can only be corresponding with it with model terminal box combination installation, and can't install with the terminal box of other types, so that this kind method of testing has been subject to certain restriction, if transform simultaneously a plurality of dissimilar lids, improved again workload and production cost; This kind test mode is only applicable to be equipped with the solar cell of detachable lid, then can't test for the solar cell that non-removable potting compound junction box is installed.
Therefore, how improving the EL test success ratio of solar cell, and improve the EL test all-purpose to different solar cells, is present those skilled in the art's problem demanding prompt solution.
