Summary of the invention
The utility model will be invented a kind of on-line automatic detection device exactly, can be apace, disposable preceding electrode layer laser grooving and scribing groove with all unit joints of solar cell all detects, how to solve the technical matters of online automatic detection laser grooving and scribing effect.
In order to realize above task; The technical scheme that the utility model adopts: design a kind of automatic detection device that is used to detect the thin-film solar cell laser rose line; Comprise test board, movable stand, mechanism for testing and data collecting instrument, its major technique characteristic is that mechanism for testing is installed on the movable stand, and a plurality of test probes are housed on the mechanism for testing; One end of this probe contacts with the laser grooving and scribing unit of solar cell, and the other end is connected with data collecting instrument.
Mechanism for testing comprises probe and fixed head and conductive rubber cover, and this conductive rubber cover coats the test cap of probe.
Movable stand is made up of motor, leading screw and crossbeam, and crossbeam is installed on the leading screw.Movable stand can move forward and backward along test board.
The cylinder of push to test probe is housed on the crossbeam.Test probe can move up and down.
Mechanism for testing is installed on the solar cell laser rose equipment, forms the all-in-one of laser grooving and scribing and detection.
Spacing between the probe on the said mechanism for testing is adjustable.Adjacent two probes in the mechanism for testing lay respectively at the both sides of laser grooving and scribing line.
The good effect that the utility model produces: adopt row's formula probe as detecting element, probe contacts each delineation unit simultaneously, and the laser grooving and scribing line in the middle of two probes with two joint conductive film layers separately; Be equivalent to the resistance (resistance is greater than 2M Ω) that resistance is very big; Test and write down the method for the resistance value of every laser grooving and scribing line with data collecting instrument and judge the laser grooving and scribing effect, need not light source, simple in structure; Test is efficient, convenient; Accuracy of judgement is realized online full inspection, guarantees battery quality.
