Full-automatic in-mold labeling and visual detection system

Abstract

The invention discloses a full-automatic in-mold labeling and visual detection system which is used for carrying out in-mold labeling and visual detection on cup-shaped products. The full-automatic in-mold labeling and visual detection system comprises a material carrying frame, a labeling device, a material moving device, a product receiving platform, a first visual detection device, a turnover mechanism, a reciprocating motion device and a conveying line; the labeling device places labels on the material carrying frame into a mold cavity and takes out the cup-shaped products subjected to in-mold injection molding and labeling, the material moving device transfers the taken-out cup-shaped products to the product receiving platform, and the turnover mechanism drives the product receiving platform to overturn to a photographing position; the first visual detection device is respectively aligned with each cup-shaped product under the driving of the reciprocating motion device and is used for carrying out visual detection on the interior of each cup-shaped product; and the conveying line receives and conveys the plurality of cup-shaped products subjected to visual inspection. Therefore, the system can simultaneously complete product in-mold labeling and detection procedures, the automation degree is high, and the machine table conversion space is reduced.

Description

technical field [0001] The invention relates to the technical field of product labeling, in particular to a fully automatic visual inspection system for in-mold labeling. Background technique [0002] In-mold labeling is a device for pasting stacked labels on blow molding and injection molding products of PP, PE, PET and other materials. In the actual working process, the printed label is put into the blowing and injection mold cavity before blow molding and injection molding. When the mold is closed for blowing and injection, the special adhesive on the label is made The glue melts and fuses with the bottle body or the surface of the injection molded part. When the mold is opened, the label has been integrally formed with the product. Since the in-mold label and the plastic part are naturally integrated and deformed with the deformation of the product, there will be no blistering or wrinkling. [0003] Generally speaking, after the product is labeled, it needs to be inspe...

Problems solved by technology

At present, the main method is to first label the product through the labeling equipment, and then transfer the processed product to the testing equipment for testing through manual or mechanical arms. It can be seen that during the labeling process of the above products, Manual switching between different machines is required, or multiple devices cooperate with each other, which consumes a lot of cost and low production efficiency
