Amount is excessive.
R4=5 < 18.1429~8.1429, then judge that the glue amount of the 4th pixel of the glue-line picture 61 is abnormal, and glue amount
It is insufficient.
R5=0 < 18.1429~8.1429, then judge that the glue amount of the 5th pixel of the glue-line picture 61 is abnormal, and glue amount
It is insufficient.
R6=14,18.1429~8.1429 range is fallen into, then judges the glue amount of the 6th pixel of the glue-line picture 61
Normally.
R7=13,18.1429~8.1429 range is fallen into, then judges the glue amount of the 7th pixel of the glue-line picture 61
Normally.
Expansion details can be deduced from the description above due to having usually intellectual in this field, do not added
It is bright.
Via above explanation, the advantages of previous embodiment, can be summarized as follows:
1, the present invention is the chromatic value with pixel array, as the basis for judging glue amount, is not only able to learn zonal
Glue amount variation, and equipment cost is low, judgment mode is simple, and as each pixel color angle value performance difference is wider, it more can be substantially
Promote the accuracy of glue amount judgement.
Furthermore 2, due to the number of aforementioned glue amount, can digitization, therefore, obtained assessment result can also be used
In the uniformity for judging glue amount, or can be as the reference of adjustment drying time, for example, aforementioned judgement difference Jn=0.8571
Corresponding shoes part 2 or region, because glue amount is more, drying time is 5 minutes, and JnShoes part 2 corresponding to=- 0.1429
Or region, because glue amount is less, drying time is 3 minutes, whereby, the glue-line 1 is enable to play maximum bonding benefit, into
And promote the quality of finished product.
As described above, only the embodiment of the present invention, when that cannot be limited the scope of implementation of the present invention with this, i.e.,
It is all according to simple equivalent changes and modifications made by claims of the present invention and description, all still belong to model of the invention
It encloses.
