Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tape cutting devices require separate cutting of carrier and cover tapes, limiting the efficiency of the cutting process.
Innovation Solution
A tape cutting processing apparatus that includes a conveyance device, detection device, folding-back member, and cutting device, controlled by a control device to overlap and cut both tapes simultaneously, ensuring the cover tape protrudes by a predetermined length from the carrier tape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the carrier tape and cover tape are cut separately by a cutting device, then the cutting can be performed with existing equipment, but the cutting processing time is extended and efficiency is limited
Solution Approach 1:
The patent combines the cutting operations for the carrier tape and cover tape into a single simultaneous cutting action. The cutting device is configured to cut both tapes at the same time using one cutting motion, merging two separate cutting processes into one unified operation. This directly resolves the technical contradiction by improving productivity through consolidation while reducing the total time required for cutting processing.
2Loss of time
If the carrier tape and cover tape are cut simultaneously, then the cutting processing time is reduced, but the positioning and overlapping control becomes more complex
Solution Approach 1:
The patent introduces a folding-back member as an intermediary device that folds the cover tape backward to create a folded state before cutting. This folding action serves as a positioning mechanism that automatically aligns the cover tape with the carrier tape at the cutting position. By using this intermediary folding mechanism, the system achieves precise positioning for simultaneous cutting without requiring complex positioning and control systems, thus resolving the technical contradiction between reduced processing time and simplified device complexity.
3Manufacturing precision
If the cover tape is folded back so that adhesion surfaces face each other, then the simultaneous cutting alignment is improved, but the folding mechanism adds device complexity
Solution Approach 1:
Instead of trying to align the cover tape and carrier tape in their normal extended positions, the patent inverts the approach by folding the cover tape backward so that its adhesion surfaces face each other. This inversion creates a naturally aligned folded state that positions the cover tape precisely relative to the carrier tape for cutting. By using this inverted folding approach rather than direct alignment mechanisms, the system achieves high cutting alignment precision while keeping the folding mechanism relatively simple.
