Abstract
The utility model discloses a EL tester, including box, block terminal and camera, the box top is the clear glass as battery cluster test platform, and on this battery cluster test platform was arranged in to the battery that awaits measuring, both ends were respectively through interconnection strip connection briquetting electrode, the briquetting electrode links to each other with the block terminal positive and negative polarities respectively and to the battery statements based on collusion direct current that awaits measuring, the box is inside to be equipped with the light reflex that is used for sending the battery cluster that the awaits measuring reflector to the camera, be equipped with the visible light optical filtering before the camera. The utility model discloses following beneficial effect has: can accomplish the detection of battery cluster behind the butt weld before stromatolite, lamination, accomplish the detection to bad cluster range upon range of before, improve the loaded down with trivial details process of doing over again, exquisite structure reduces the space and occupies the detection of non - darkroom, convenient operation simultaneously.
Description
Technical field
The utility model relates to a kind of checkout gear of product quality, is specially the EL checkout gear to photovoltaic cell string internal flaw.
Background technology
The production of photovoltaic products is spliced by multi-disc cell piece, cell piece itself is thin and crisp, very easily cell piece is damaged in assembling process, and the complex manufacturing of cell piece own, comprises the sightless defect of some naked eyes, can be identified the invisible defect of naked eyes by EL detection technique, concrete principle is for pass to certain electric current to battery, cell piece sends infrared light, by using camera to take pictures to cell piece, identifies cell piece internal flaw.Current EL testing equipment mainly detects photovoltaic products afterwards and after laminating packaging stacked, and the defect of discovery need carry out process of doing over again after whole dismounting, and operation is loaded down with trivial details; And between the test of the tester darkroom that to be volume larger, complex operation.
Utility model content
The utility model provides a kind of EL checkout gear, improving loaded down with trivial details operation of doing over again, testing under visible light, reducing operation sequence, having filled up the vacancy that battery strings EL detects simultaneously by carrying out battery strings detecting.
The utility model solves the technical scheme that its technical problem adopts:
A kind of EL tester, comprises casing, distribution box and camera; Described casing top is the clear glass as battery strings test platform, mesuring battary is placed on this battery strings test platform, two ends connect briquetting electrode respectively by interconnecting strip, and described briquetting electrode is connected with distribution box positive and negative polarities respectively and supplies direct current to battery strings to be measured; The described box house light be provided with for being sent by mesuring battary string reflexes to the reflective mirror of camera, is provided with visible ray optical filtering before described camera.
In addition, the computer be connected with described camera can also be comprised in tester of the present utility model, testing result is directly presented on the display of computer.
Reflective mirror the distance that can increase light between battery strings and camera is set, solve camera focus problem; Use optical filtering to filter out visible ray, solve EL and test the problem that must complete in darkroom; Use briquetting electrode to be connected with the interconnecting strip at battery strings two ends, can avoid because crocodile clip connects the problem that distortion causes cell piece fragmentation.
Therefore, the utility model has following beneficial effect: can complete the detection of battery strings after welding before lamination, lamination, completes the check processing to bad string before stacked, improve loaded down with trivial details operation of doing over again, simultaneously exquisite structure reduces space hold, and non-darkroom is detected, easy to operate.

Fig. 2 is structural representation of the present utility model, in figure: 1. casing, 2. battery strings test platform, 3. reflective mirror, 4. distribution box, 5. camera, 6. visible ray optical filtering, 7. computer, 8. battery strings, 9. briquetting electrode.
Fig. 3 is the connection diagram of battery strings and briquetting electrode in the utility model.
Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
In FIG, distribution box 4 gives battery strings 8 for direct current, and after energising, battery strings 8 sends infrared light, after visible ray optical filtering 6 filters out visible ray, gathered by camera 5 infrared light that battery strings 8 sends, output image on computer 7 and show, handled easily personnel judge testing result.
In fig. 2, casing 1 is cuboid, clear glass is installed as battery strings test platform 2 at the top of casing, make camera can capture image by glass, camera 5 is fixed on the other centre position of top test platform, at bottom half, reflective mirror 3 is installed, increase camera 5 and battery strings 8 light distance, reflective mirror 3 adjusts certain angle, makes the light reflection of battery strings 8 in camera 5, and camera 5 lens direction aims at reflective mirror.Before camera 5 camera lens, optical filtering 6 is installed, filters out visible ray, the infrared light only sent by battery strings 8; Distribution box 4 is installed on casing 1 bottom viewfinder 3 side or tank wall, provides alternating current to equipment, provide direct current to battery strings 8 and control the break-make of battery strings; At casing 1, the detected image that computer 7 receives camera output is installed.
In figure 3, top battery string test platform 2 use briquetting electrode 9 pairs of battery strings 8 carry out connection for direct current, two cube electrodes use wire 11 to connect the both positive and negative polarity of DC power supply respectively, electrode being overwhelmed battery strings two ends grows in the interconnecting strip 10 of cell piece, with test platform close contact, complete energising and connect.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
