Tape Material Control Apparatus for Precision Sticker Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tape material control systems face limitations in versatility due to restricted length of tape that can be wound around reels, leading to low precision and high workloads in automated sticker application processes.
Innovation Solution
A tape material control apparatus with a supply portion, rollers, and a controller that individually controls the feeding speed, conveyance speed, and winding speed of the tape material, allowing for precise control and extended tape length handling, and includes a cutting unit with suction attraction for improved versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the tape material is wound around a reel by rotating the reel while moving it along the tool, then the tape material can be supplied to the reel, but the length of tape that can be wound is restricted
Solution Approach 1:
The system divides the tape handling process into separate functions: a first roller feeds the tape material from the supply reel, while a second roller conveys the peeling member. This segmentation allows independent control of each roller's rotation speed, enabling the tape to be fed and wound without being constrained by the reel's movement range, thus extending the handleable tape length while maintaining system versatility
Solution Approach 2:
The first roller acts as an intermediary between the supply reel and the peeling position, and the second roller serves as an intermediary for conveying the peeling member. These intermediary rollers enable precise speed control and decouple the tape feeding process from the reel movement constraints, allowing longer tape lengths to be handled effectively
2Manufacturing precision
If automated sticker application is implemented, then precision and speed are improved, but the system complexity increases
Solution Approach 1:
The controller provides centralized control over multiple rollers (first roller for tape feeding, second roller for peeling member conveyance, and third roller for winding), enabling a single automated system to perform multiple functions with coordinated precision. This multi-functionality approach achieves high sticker application precision while managing system complexity through integrated control
3Measurement precision
If the feeding speed, conveyance speed, and winding speed are individually controlled, then the precision of tape material control is improved, but the control system complexity increases
Solution Approach 1:
The system implements dynamic speed control where the first rotary driving portion, second rotary driving portion, and third rotary driving portion can independently adjust the rotation speeds of their respective rollers. This dynamic control capability allows precise matching of feeding speed, conveyance speed, and winding speed to achieve accurate tape material control while the controller coordinates these adjustments to manage system complexity
