Label Suction Pad Motion for Wrinkle-Free Plate Product Pasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product transfer systems face challenges in pasting labels on plate-like products without causing deformation or wrinkles, and in achieving flexible positioning and orientation of labels during the pasting process.
Innovation Solution
A product transfer apparatus with a suction cup system that includes a label suction part with up-down movement capability, allowing for independent control of label placement on plate-like products, enabling labels to be suctioned and placed at optional positions and orientations without deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional suction pads are used to suck labels, then the label can be held for transfer, but the label is deformed with wrinkles causing poor pasting quality
Solution Approach 1:
The suction system is divided into two independent parts: a product suction pad part for holding the plate-like product, and a separate label suction part for holding the label. This segmentation allows each part to be optimized for its specific function, preventing label deformation while maintaining reliable label holding capability.
Solution Approach 2:
A label pad acts as an intermediary between the label and the suction system. The label pad has a flat suction surface that contacts the label, distributing suction force evenly across the label surface to prevent deformation and wrinkles, while still enabling reliable label holding and transfer.
2Adaptability or versatility
If labels are pasted within the suction range of product suction pads, then the label can be held during transfer, but the pasting position and orientation are limited
Solution Approach 1:
The label suction part is designed to be movable relative to the product suction pad part, with capabilities for horizontal movement, vertical movement, and rotation. This dynamic configuration allows the label to be positioned and oriented at any location on the product surface, greatly enhancing pasting flexibility while maintaining precise position control through coordinated movement.

AI summary
A product transfer apparatus includes a product suction pad part having a suction cup part capable of sucking a plate-like product, a transfer base whose lower part has the product suction pad part, and a label suction part having a label pad, which is able to suck a label to be pasted to the product, and an up-down function of moving the label pad up and down between a position upper than and a position lower than the position of a front end of the suction cup part.
