A kind of fast non-contact knife adjusting device and knife adjusting method for glass cutting machine

Abstract

The invention relates to the glass cutting precision, and discloses a device for quickly adjusting knives of glass cutting machines in a non-contact manner. The device comprises a movement platform system, an optical imaging system, an image processing system and a result displaying system. The movement platform system is used for shifting the optical imaging system and the image processing system; the optical imaging system is used for carrying out amplification imaging on knife points of knife boxes and transmitting image data to the image processing system; the image processing system is used for analyzing and processing the image data in the optical imaging system, extracting locations of the knife points and outputting results of the distances from the locations of the knife points to central locations to the result displaying system; data of movement amount of movement platforms and the results, of the distances from the locations of the knife points to the central locations, obtained by the image processing system are displayed by the result displaying system. The device has the advantages that knife box adjusting operation procedures can be simplified, accordingly, the work efficiency can be improved, and the glass cutting precision can be fundamentally improved.

Description

Technical field [0001] The invention belongs to the technical field of optical precision measurement, and relates to a fast non-contact knife adjustment device and a knife adjustment method of a glass cutting machine that can be used to accurately assist assembly and detection of a knife box on a multi-knife glass cutting machine. Background technique [0002] Before using a multi-knife glass cutting machine to cut glass, it is usually necessary to adjust the distance between the knife box and the knife box according to customer needs. Generally, the knife box has a pointer and a steel ruler with a scale on the cutting bridge. The worker uses the scale indication to coarsely adjust and position the distance between the knife boxes, and then perform trial cutting after fixing, and use the vernier caliper to measure the cutting distance, and then continuously make fine adjustments to meet the precise distance requirements. However, there are the following drawbacks in actual use: ...

AI Technical Summary

Problems solved by technology

[0003] First of all, for the cutting of some glass products with high precision requirements, such as slide glass, optical glass, etc., the precision requirements are generally plus or minus 0.05mm or even higher. Therefore, for the adjustment of high precision knife boxes, the operator's experience and Repeated adjustments can be realized, not only the operation is cumbersome, but also for a glass cutting machine with dozens of knives, sometimes it takes at least half a day to a day to complete

Secondly, during the adjustment period, it is necessary to use glass for continuous trial cutting, so it also forms a waste of material virtually.

[0004] In view of the above problems, there is less research on it at home and abroad at present, and more is the method of using a high-precision measuring ruler to replace the steel ruler of the cutting bridge, such as the Chinese patent "Glass Cutting Machine Rapid Knife Adjusting Device" (Patent No.: 200620072504.5) In the paper, it is proposed to use a high-precision magnetic ruler to quickly adjust the knife box. However, when cutting glass, the accuracy of the distance depends fundamentally on the diamond tip of the knife box that is in contact with the glass, and because the knife box processing Due to technical problems, it is difficult for most knife boxes to ensure that the tip of the knife is completely in the center of the knife box, so only ensuring the accuracy of the distance between the knife boxes cannot guarantee the accuracy of the cutting glass distance
