Synchronized Suction Peeling for Wrinkle-Free Sticker Affixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sticker affixing systems often result in warpage or wrinkling of stickers when peeled off from release paper, leading to improper affixing to objects.
Innovation Solution
An articulated robot system with a suction tool synchronized with a sticker feeder to peel stickers parallel to the release paper conveyance, using a controller to manage the suction tool's movement and timing, ensuring the sticker is maintained in shape during peeling and affixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a suction tool is used to peel off the sticker from the release paper, then the sticker can be removed from the release paper, but the sticker develops warpage or wrinkles during the peeling process
Solution Approach 1:
The suction tool is made movable relative to the release paper through synchronization with the sticker feeder. The suction tool moves in parallel to the conveyance direction of the release paper at a speed equal to the conveyance speed, dynamically adapting to the peeling process to prevent wrinkles while maintaining productivity
Solution Approach 2:
The patent replaces traditional mechanical peeling methods with a suction-based system. By using suction force instead of mechanical scraping or lifting, the sticker can be peeled without applying localized stresses that cause warpage or wrinkles, while still achieving efficient removal
2Speed
If the suction tool moves faster than the release paper conveyance speed, then the peeling process is accelerated, but the sticker shape is distorted due to mismatched movement speeds
Solution Approach 1:
The system uses synchronization between the sticker feeder and the suction tool movement. The controller coordinates the conveyance speed of the release paper with the movement speed of the suction tool, ensuring they move at matching speeds to maintain sticker shape while achieving efficient peeling
Solution Approach 2:
The suction tool's movement is made dynamic and adjustable, matching the conveyance speed of the release paper in real-time. This dynamic synchronization allows the system to adapt to different operating conditions while maintaining both speed and precision

AI summary
Generation of a wrinkle is prevented in a sticker when the sticker is peeled off from a release paper. A sticker affixing system includes an articulated robot, a controller that controls the articulated robot, a suction tool attached to a distal end of the articulated robot, and a sticker feeder that conveys a release paper. The suction tool is sucked to the sticker on the release paper. The controller causes the articulated robot to execute an operation of moving the suction tool in parallel with the release paper at a constant speed of the release paper in synchronization with the sticker feeder, an operation of peeling off the sticker at an edge A of a peeling base of the release paper, and an operation of affixing the sticker to the object to which the sticker is affixed.
