Description
Technical field
The present invention relates to a kind of crack detection device.It specifically is a kind of crackle detecting instrument for solar cell panel.The production testing field that is used for solar panel.
Background technology
Solar cell is a kind of device that sun power is changed into electric energy, solar cell is according to the difference of material therefor, and can be divided into silicon is solar cell, multi-element compounds thin-film solar cells, polymer multi-layer modified electrode type solar cell and nano-crystalline solar battery four big classes.Wherein silicon is that solar cell is the most common, and these solar panels can apply external force in process of production inevitably on little plate, will occur the crackle that length, direction have nothing in common with each other sometimes on the surface of plate.These have the cell panel of crackle, in case be mounted in the solar battery group, will have a strong impact on the performance of entire cell module.In traditional production run, the integrity of these solar panels is mainly by human eye detection.The method of this manual detection not only wastes time and energy, and because the singularity of solar cell material, the phenomenon of omission occurs through regular meeting, and this has brought difficulty just for the quality of raising product.Therefore be necessary to design a kind of automatic checkout system, can carry out contactless, detection with no damage to the integrity of solar panel, the bad sheet that will have crackle is separated automatically.
Summary of the invention
The objective of the invention is to overcome the deficiency of existing detection means, provide a kind of and can be advantageously applied to the instrument, the particularly device that the crackle on the solar panel can be detected automatically that the solar cell integrity detects.Because mostly solar panel is higher by reflectivity, the material that emissivity is lower constitutes, so this crackle detecting instrument for solar cell panel uses laser as excitation source, produce the infrared signal of this point by the laser energy of infrared remote receiver reception cell panel surface reflection, through pushing away the scanning of sweeping device both direction, can obtain the infrared image signal of whole solar cell plate again.Use the Intelligent Recognition analysis software that image is handled at last, promptly can detect solar panel and whether have crackle, for a kind of noncontact, the undamaged new mode of providing is provided for the integrity of solar panel.
The object of the present invention is achieved like this:
A kind of crackle detecting instrument for solar cell panel comprises laser controller, rotation mirror controller, lasing light emitter, catoptron, rotation mirror, imaging len, line array CCD, pushes away and sweep drive unit, computing machine and objective table.Characteristics are that lasing light emitter, catoptron, rotation mirror, imaging len, line array CCD become light path to connect successively: lasing light emitter emitted laser bundle is through after the mirror reflects, shine and rotate on the mirror, rotate mirror according to certain frequency rotation, laser beam is reflexed to tested solar panel surface, and realize its surperficial line scanning, by the laser energy of cell panel surface reflection through being imaged on the line array CCD behind the imaging len, CCD with image data acquiring in computing machine.
Circuit connects: the ccd output signal cable connects computing machine, and computing machine connects laser controller, rotates the mirror controller and push away and sweep drive unit; Laser controller is connected on the lasing light emitter, the work of control lasing light emitter; Rotate the mirror controller and be connected on the rotation mirror, control is rotated mirror and is rotated according to certain frequency; Push away the stepper motor of sweeping drive unit and connect objective table by ball-screw, solar panel places on the objective table, pushes away to sweep the translation of drive unit driving objective table, realizes pushing away of solar panel swept.
Through rotating the mirror reflection laser beam solar panel surface line scanning and objective table translation are realized column scan to cell panel, can obtain whole tested solar panel laser light reflected energygram picture at last.This view data has comprised the infrared signal on solar panel surface, promptly can on display, show through Computer Processing, by the Intelligent Recognition processing module in the computing machine this infrared image is carried out Treatment Analysis then, promptly the crack detection that solar panel exists can be come out, thus the automatic detection of realization solar panel surface integrity.
Above-mentioned excitation source is the lasing light emitter that can launch diameter 10-50 micron laser beam, and its transmission frequency can be selected as required flexibly; Described rotation mirror can be three mirror contact lens or polygonal mirror; Described line array CCD is an infrared CCD, according to the material difference of tested cell panel, also can use common monochrome or colored CCD.
The present invention is mapped to laser beam on the solar panel surface by rotating mirror reversal, realization is to the transient heating of solar cell surface analyzing spot, use line array CCD to gather the infrared energy of cell panel radiation, push away by detection and to sweep on the entire cell plate image that the back obtains, can judge promptly whether this solar panel is intact to sudden change information.This detection mode does not contact tested solar panel surface, can not cause damage to cell panel in testing process, can substitute artificial realization and detect automatically.
