Problems solved by technology

The disadvantage of this method is that each pair of infrared emitting and receiving tubes in the detection device covers a small range of angles. Although increasing the number of pairs of emitting and receiving tubes can expand the coverage angle, there are still missed detection areas.
These transmitting and receiving tubes are inconvenient to adjust, and must be readjusted whenever the product is changed, especially during the inspection process, once the relative angle between the transmitting tube and the receiving tube changes, it is difficult to readjust to the best state

Embodiment Construction

[0017] The detection method for glass bottles and jars of the present invention includes computer image processing and various calculation methods. The light source is projected on the mouth of the glass bottle, and the light screen is used as the background of the glass bottle to be inspected. The glass bottle is rotated 360 degrees, and 15 to 35 images of the bottle mouth are taken during the rotation process. The sequence captured by the computer for the same bottle The images are processed and calculated one by one. As long as a bright spot reflected by the crack of the bottle mouth is found in one of them, it can be determined that there is a crack defect in the bottle mouth.

[0018] When the inspected bottle rotates a circle, the images of multiple series of bottles captured show the state of the entire bottle mouth. When the computer processes the image, the image segmentation algorithm is used to cut out part of the image of the bottle mouth in each picture as the com...

Abstract

A method and apparatus for in-line checking of glass bottles without contact features that under the control of computer, the multiple mouth images of a rotating bottle is picked up and then processed one by one to finde the bright sport reflected by the mirror of cracked mouth, so determining that the bottle mouth is cracke and rejecting out the bottle automatically. Its advantages are high accuracy and no leakage detection.

Description

(1) Technical field [0001] The invention relates to a glass bottle and jar detection method and a glass bottle and jar detection device specially designed for implementing the method. (2) Technical background [0002] There are two types of detection methods for glass bottles and jars: contact and non-contact. [0003] For the detection of the size and unevenness of the mouth of glass bottles and jars, the verticality of the bottle body, etc., contact-type automatic detection of glass bottles and jars is mostly used, and the measurement is generally carried out by mechanical sensing. The glass bottle and can detection device adopting this type of detection method can detect a single item, such as the Chinese invention patent application CN2414005 "Glass bottle vertical axis deviation test positioning device", CN2276628 "Glass bottle vertical axis deviation measuring instrument" and so on. Moreover, the machining precision of the detection device is required to be extremely ...
