Abstract
The invention discloses a method for rapidly testing the symmetry degree of a product by comparing the product by utilizing a film negative and a projector. The method comprises the following steps of: arranging the film negative for calibrating on a display screen of a projector, so that data measurement is not required in the process of testing the symmetry degree of the product; and judging whether the size of the product is within a calibration interval according to a calibration reference line so as to test the symmetry degree of the product. According to the method disclosed by the invention, the test efficiency and quality of the product are greatly improved.
Description
Technical field
The present invention relates to a kind of detection method, particularly a kind of method of utilizing film egative film and projector comparison product quick test product symmetry.
Background technology
When utilizing projector testing product symmetry, need to judge through a series of DATA REASONING whether product meets the requirements, the measurement of data need expend the long period, makes checkability very low, and occurs the wrongheaded phenomenon of assay easily.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of method of utilizing film egative film and projector comparison product quick test product symmetry, this method can be proofreaded the symmetry of product fast, has greatly improved checkability and quality.
The present invention for the technical scheme that solves its technical matters and adopt is: a kind of method of utilizing film egative film and projector comparison product quick test product symmetry, it may further comprise the steps
A. make a film egative film, and a datum line is set on egative film;
B. the enlargement factor of observing according to the size and the projector of need checks product is being provided with on the film egative film between a calibration areas, is the clearance space between two lubber-lines parallel with datum line between calibration areas;
C. will check product to be positioned under the sight glass of projector, simultaneously film Negative plate paster be placed on the display screen of projector;
D. on the display screen of projector, check the datum line of product to align with need the datum line of film egative film, the dimension line that observe to need the check product whether between calibration areas in, if between calibration areas, represent that then the product symmetry meets the requirements, if in not between calibration areas, represent that then the product symmetry is undesirable.
The invention has the beneficial effects as follows: this method utilization is provided with the display screen of a film egative film that is used to calibrate at projector, make and in the process of check product symmetry, need not measurement data, by the alignment fiducials line, judge in whether product size is between calibration areas and check its symmetry, greatly improved the efficient and the quality of the examination and test of products.
Description of drawings
Fig. 1 is the synoptic diagram of film egative film among the present invention.
Embodiment
Embodiment: a kind of method of utilizing film egative film and projector comparison product quick test product symmetry, it may further comprise the steps:
A. make a film egative film 1, and a datum line 2 is set on egative film;
B. the enlargement factor of observing according to the size and the projector of need checks product is being provided with between a calibration areas 4 on the film egative film 1, and 4 is clearance space between two lubber-lines 3 parallel with datum line between calibration areas;
C. will check product to be positioned under the sight glass of projector, simultaneously film egative film 1 be adhered on the display screen of projector;
D. on the display screen of projector, check the datum line of product to align with need the datum line 2 of film egative film 1, whether the dimension line that observe to need the check product is between calibration areas in 4, if between calibration areas, represent that then the product symmetry meets the requirements, if in not between calibration areas, represent that then the product symmetry is undesirable.
