Sticker Affixing Robot with Inclined Suction and Pressing Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sticker affixing systems often result in warpage, wrinkles, or bubbles when stickers are peeled off and affixed to objects, leading to inadequate adhesion.
Innovation Solution
An articulated robot-based sticker affixing system with a suction tool featuring a suction portion and a pressing portion, where the suction surface is inclined and moved along the object's surface, and the suction force is adjusted to prevent bubbles by using a rotatable roller, spatula, or corner pressing portions, and varying suction block configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suction tool is used to peel off the sticker from the release paper, then the sticker can be held and transferred, but bubbles may be generated between the sticker and the object during affixing
Solution Approach 1:
The pressing portion acts as an intermediary between the suction tool and the sticker. It applies pressure to the sticker while the suction tool moves along the object surface, forcing air out from between the sticker and object, thereby preventing bubble formation while maintaining reliable adhesion
Solution Approach 2:
The system performs preliminary action by applying pressure to the sticker before complete adhesion is achieved. The pressing portion presses the sticker against the object surface during the affixing process, proactively preventing bubble formation rather than addressing it after the fact
2Manufacturing precision
If the suction force is increased to hold the sticker firmly, then the sticker can be peeled off without deformation, but the sticker becomes difficult to separate from the suction tool after affixing
Solution Approach 1:
The suction force is made dynamic rather than static. The controller adjusts the suction force based on the operational phase: higher suction force during peeling to prevent deformation, and lower suction force during separation to enable easy release. This dynamic adjustment resolves the contradiction between holding firmness and separation ease
Solution Approach 2:
The suction force parameter is changed according to the process stage. By modifying the suction force from high (during peeling) to low (during separation), the system achieves both deformation-free handling and easy separation without requiring different physical mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents bubble formation and ensures proper adhesion by uniformly applying pressure and adjusting suction force, allowing for easy separation and attachment without warping or wrinkling the sticker.

AI summary
Generation of a wrinkle is prevented when a sticker (150) is affixed to an object (130). A sticker affixing system (10) includes an articulated robot (100), a controller (200) configured to control the articulated robot (100), and a suction tool (110) attached to a distal end of the articulated robot (100). The suction tool (110) includes a suction portion (501) configured to hold a sticker (150) and a pressing portion (502) configured to affix the sticker (150) to an object (130) to which the sticker (150) is affixed. The controller (200) causes the articulated robot (100) to execute an operation of inclining a suction surface of the suction portion (501) with respect to a surface of the object (130) and an operation of moving the suction tool (110) along the surface of the object (130). The pressing portion (502) presses the sticker (150) against the surface of the object (130) while the suction tool (110) moves along the surface of object (130).
