It compares in the prior art, for being shone using side position, lamp detecting method provided by the invention, by container bottom
Carry out illumination, the eyesight for protecting operator of high degree, solve will not because caused by human eye fatigue testing result it is not smart
True problem.
Also, it, can be in the delivery position of solution and bottom when container of the light beam to solution to be detected carries out bottom irradiation
Apparent naked eyes identification region is generated, therefore by making the container lean set angle of solution to be detected to the greatest extent different
Object is stopped to container bottom, and then improves lamp inspection efficiency.
A kind of lamp detecting method provided by the invention is described below with reference to specific experiment data, specific as follows:
Experiment one: the even container of selection bottom uneven distribution, the solution that filling common lamp inspection desk illumination can not penetrate will not
The glass dregs of same specification are put at random is wherein mixed into 100 bottles with container in the bottled product of solution at random, and the present invention is respectively adopted
