Description
Technical field
The present invention relates to the photovoltaic module technical field, particularly a kind of EL pick-up unit that scans solar module.
Background technology
At present; In the production run of solar module battery sheet; After solar module is finished the IV test; Can carry out electroluminescence (EL) test, this test mainly is for whether the battery sheet of measuring in the solar module conceals the phenomenon of splitting, breaking grid, rosin joint, short circuit and fragmentation, is the Quality Identification to solar module.
The EL tester equipment that uses now is the camera that the infrared light responsive of a wide-angle lens is installed a camera bellows the inside; When detecting, solar module is placed in the camera bellows; With camera the solar module of switching on is carried out sensitization and take, the infrared light that during this exposure, needed 15 seconds to come induced electrified solar module to send.Practical operation finds that in the photo that shooting is come out, the centre bit offset of assembly is bright and clear; But part is but dark partially and not fogging clear on the edge of, and the defects of battery plate that counts so all concentrates on the centre of whole assembly, out of true very; Cause the main cause of this situation to be, wide-angle lens depth when in use is very large, so will cause edge of image partly to distort; The focal length of camera lens is short more; The distance of taking is near more, and this defective is just obvious more, just our frequent said aberration.
Summary of the invention
In order to overcome above problem; The invention provides a kind of EL pick-up unit that scans solar module,, make convenient, the science of research to realize effectively improving the marginal portion sharpness of solar module EL test; Improve detection speed, reduce the advantage of production cost.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of EL pick-up unit that scans solar module comprises the linear optics scanner head 1, belt 2, stepper motor 3, broad-adjustable component track 6, scan track 7, signal processing circuit board 8, the data line 9 that are arranged in the camera bellows 4; Cover the computing machine 10 that is connected at the camera bellows on the camera bellows 4 lid 5 with through connecting link on the camera bellows 4.
Further; Linear optics scanner head 1 comprises the printing opacity magazine with light penetrating slit 11; Be located at the level crossing 12 below this light penetrating slit 11, be located at the lens 13 of the light reflection position of said level crossing 12, and the infrared sensitization CCD chip 14 and CCD chip circuit plate 15 that are located at said lens 13 rear ends; Infrared sensitization CCD chip 14 is electrically connected with CCD chip circuit plate 15.
Further, level crossing 12 becomes miter angle with surface level.
Further, the equal in length of the length of light penetrating slit 11 and linear optics scanner head 1.
Further, the display of computing machine 10 comprises touch-screen.
The EL pick-up unit of scanning solar module of the present invention; Can improve the sharpness of the marginal portion of solar module EL test; Owing to need not use wide-angle lens,, let research is more convenient, science so measure just more precisely; Can let simultaneously detection speed accelerate, reduce production cost.

Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
See also Fig. 1, Fig. 1 is the agent structure synoptic diagram of the EL pick-up unit of scanning solar module of the present invention.As shown in Figure 1, the main body of the EL pick-up unit of this scanning solar module is made up of linear optics scanner head 1, belt 2, stepper motor 3, camera bellows 4, camera bellows lid 5, component track 6, scan track 7, signal processing circuit board 8, data line 9 and computing machine 10.
Scan track 7 and component track 6 are arranged in the camera bellows 4; Scan track mainly is the sliding rail that is provided with for linear optics scanner head 1; Component track 6 is a pair of tracks that can support to put the solar module that will detect; Component track 6 can be carried out left and right sides width adjusting according to the solar module different specifications, and the main effect of camera bellows 4 is when detecting, to prevent extraneous light Interference Detection data, during device work camera bellows lid 5 cover on camera bellows 4, guarantee light tight.Two positive and negative electric wires that the solar cell panel assembly of test is supplied power also are installed in the camera bellows 4; Linear optics scanner head 1 is contained in scan track 7 and is connected on the stepper motor 3 by belt 2; Stepper motor 3 is through the gait of march of the control of the chip pre-set programs on the signal processing circuit board 8 belt 2; Belt 2 drives linear light line sweep head 1, and the speed of controlling linear optical scanning head 1 mainly is for gated sweep resolution, reduces the noise of image.The light inlet of supposing linear optics scanner head 1 is the X axle, and scanning guide rail 7 is the Y axle, and it is at the uniform velocity mobile on the Y axle that 2 of belts drag linear optical scanning head 1 so.
