Technical field
The present invention relates to a kind of pick-up unit of solar photovoltaic assembly hidden danger, especially a kind of defects of battery plate of solar energy photovoltaic subassembly detection method and detector.
Background technology
The hidden danger that solar photovoltaic assembly may exist, after using existing testing of equipment technology mainly to concentrate on the assembly lamination, lamination encapsulation back and piecing together after the frame, product and test mode mainly contain following problem or shortcoming: because the problem that welding or raw material take place has been found feedback delay one or more programs; The delay of bad battery sheet finds to have improved the complexity and the cost of labor of doing over again and changing sheet.
There is following shortcoming too in the equipment that solar photovoltaic assembly is detected: take time and effort; Shortage is to the timely feedback of the single weldering of preceding working procedure series welding; The customizable component laminating technology of lacking flexibility individual character detects solution.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the shortcoming and defect of above-mentioned existence, provide a kind of defects of battery plate of solar energy photovoltaic subassembly detection method and detector.
The technical solution adopted for the present invention to solve the technical problems is: a kind of defect inspection method of battery plate of solar energy photovoltaic subassembly, and this method step is as follows:
(1), earlier the battery sheet is carried out single weldering;
(2), again the battery sheet of single postwelding is carried out series welding;
(3), series welding is good battery sheet is put into the EL defects detection that the EL testing apparatus is carried out the battery sheet;
(4), detect good battery sheet and carry out operations such as lamination, lamination, packing.
The concrete steps of described EL defect inspection method are as follows,
(1), current regulator power supply is controlled, and realized the steady current input of direct current by electrode connection system in the darkroom by host computer;
(2), the testing component in the darkroom carries out image acquisition to testing component after connecting the steady current of direct current;
(3), will collect to such an extent that test result is input to host computer by video camera, display by the display that is connected with host computer then;
It carries out the defect detector of battery plate of solar energy photovoltaic subassembly of the defect inspection method of battery plate of solar energy photovoltaic subassembly, described detector comprises the darkroom, the inside in darkroom be provided with stack on drawer and following drawer, respectively be provided with the ultra-clear glasses platform in last drawer and the following drawer, in the bottom in darkroom 45 optical grade high reflection mirror and image capture device are installed, 45 optical grade high reflection mirror and image capture device are positioned at the below of drawer down, and the ultra-clear glasses platform is equipped with keeper electrode.
The invention has the beneficial effects as follows that flow process was carried out the personalized customization service when the present invention can be by different assembly worker, realize the lean production flow process that equalization is produced; Detection method can be simplified the processing of doing over again after pinpointing the problems, carrying out to the single weldering of preceding working procedure series welding in time feeds back, better realize pre-control and preventive measure, flow process is carried out the personalized customization service during by different assembly worker, realize the lean production flow process that equalization is produced, testing component can be pinpointed the problems after by lamination in problem that welding or raw material take place and just be pinpointed the problems before advanceing to lamination, can shift to an earlier date one or more operations after discovery and the feedback, the discovery in advance of bad battery sheet has reduced the complexity and the cost of labor of doing over again and changing sheet.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Among the figure: 1. darkroom, 2. go up drawer, 3. play drawer, 4. ultra-clear glasses platform, 5.45 ° of angle optical grade high reflection mirrors, 6. image capture devices.
Embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
The defect inspection method of battery plate of solar energy photovoltaic subassembly, this method step is as follows:
(1), earlier the battery sheet is carried out single weldering;
(2), again the battery sheet of single postwelding is carried out series welding;
(3), series welding is good battery sheet is put into the EL defects detection that the EL testing apparatus is carried out the battery sheet;
(4), detect good battery sheet and carry out operations such as lamination, lamination, packing.
The concrete steps of EL defect inspection method are as follows,
(1), current regulator power supply is controlled, and realized the steady current input of direct current by electrode connection system in the darkroom by host computer;
(2), the testing component in the darkroom carries out image acquisition to testing component after connecting the steady current of direct current;
(3), will collect to such an extent that test result is input to host computer by video camera, display by the display that is connected with host computer then;
Defects of battery plate of solar energy photovoltaic subassembly detector as shown in Figure 1, detector comprises darkroom 1, the inside in darkroom 1 be provided with stack on drawer 2 and following drawer 3, respectively be provided with ultra-clear glasses platform 4 in last drawer 2 and the following drawer 3,1 bottom is equipped with 45 optical grade high reflection mirror 5 and image capture device 6 in the darkroom, 45 optical grade high reflection mirror 5 is positioned at the below of drawer 3 down with image capture device 6, ultra-clear glasses platform 4 is equipped with keeper electrode, puts with the internal series-connection and the location of realizing 6 string 125mm*12 or 156mm*10 battery strings.
The present invention also comprise add electric installation, be data collection and analysis equipment and display with the host computer, image capture device 6 is made up of video camera and technical grade infrared lens, but drawer 2 folding and unfolding testing components on the drawer one-in-and-one-out, do test at following drawer 3, last drawer 2 folding and unfolding testing components finish, after following drawer 3 tests are finished, 2 also commutative turnover states of drawer, so circulation.
Introduce the course of work of defects of battery plate of solar energy photovoltaic subassembly detector below:
To go up drawer 2 and following drawer 3 splits, ultra-clear glasses platform 4 is the drawer platform, say that testing component is placed on the ultra-clear glasses platform, when entering the darkroom, drawer must realize airtight shading, the image acquisition equipment 6 that install 5 pairs of bottoms of the 45 optical grade high reflection mirror that install system bottom in darkroom can collect the testing component image that enters the darkroom from catoptron, add electric installation input steady current, video camera in the image capture device is realized control automatically by the software electronic information, when entering product, in time captures steady current the image of testing component in the 45 optical grade high reflection mirror 5, test result enters host computer by the gamma camera collection, by 2 displays being connected with main frame test result is presented in face of the operating personnel then.
Adding electric installation is 0-0A, 0-64V current regulator power supply, can be realized the input of direct current steady current by electrode connection system in the darkroom by software control.
