Abstract

The invention provides a product fully-opened hard box flatness detection method and device. The product fully-opened hard box flatness detection method comprises steps of defining a reference surface; measuring the height values of four first specified positions of a first plane relative to the reference surface and the height value of a second specified position of the first plane relative to the reference surface; calculating the ideal height value of the first plane and the flatness component of the first plane; measuring the height values of four third specified positions of a second plane relative to the reference surface and the height value of a fourth specified position of the second plane relative to the reference surface; calculating the ideal height value of the second plane and the flatness component of the second plane; and calculating the flatness of the product fully-opened hard box according to the flatness component of the first plane and the flatness component of the second plane. By employing the product fully-opened hard box flatness detection method and device, the flatness of the surface of the molded box can be monitored and evaluated effectively in real time, and the flatness value of the product fully-opened hard box can be obtained conveniently, quickly and accurately.

Description

technical field

[0001] The invention belongs to the technical field of flatness inspection of packaged printed matter, and relates to a method and equipment for detecting the flatness of a hard box, in particular to a method and equipment for testing the flatness of a fully open hard box for a product. Background technique

[0002] Zhonghua Hard Box (Full Open Type), Panda Hard Box (16pcs Full Open Type), etc. are well recognized by consumers for their brand reputation and generous packaging appearance. The outer packaging of this type of product is made of multi-layer paper box embryos, and the outer surface is fully hand-glued with adhesive as the forming medium. The flatness of the box surface after molding is an important aspect to consider whether the box packaging is good or not.

[0003] Because the box body is susceptible to the combined effect of the material characteristics of the box embryo, adhesive, and environmental temperature and humidity during the forming a...
