Carrier Tape Loading Roller With Recesses for Thick Tape Feeders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tape conveyance devices struggle to efficiently convey thick carrier tapes, such as embossed tapes, due to their larger thickness, leading to stagnation and increased work burden and time in the loading process.
Innovation Solution
A tape conveyance assistance device is introduced, featuring a roller with recessed portions to temporarily accommodate the front end of the carrier tape, applying a propulsive force to ensure smooth conveyance by bonding a cover tape to the base tape with cavities, using an auxiliary roller biased along the conveyance path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cylindrical conveyance roller is used, then thin carrier tapes can be easily conveyed, but thick carrier tapes cannot be inserted and may stagnate
Solution Approach 1:
The roller surface is modified with localized recessed portions that create variable geometry - smooth cylindrical sections for thin tapes and recessed sections for thick tapes. This local quality change allows the same roller to adapt to different tape thicknesses without requiring multiple rollers.
Solution Approach 2:
The recessed portions on the roller surface dynamically adapt to the thickness of the carrier tape being conveyed. When a thick tape is inserted, the recessed portions provide the necessary clearance and accommodation, allowing the roller to maintain contact and propulsion capability across varying tape thicknesses.
2Device complexity
If a cylindrical roller without recessed portions is used, then the structure is simple, but thick carrier tapes stagnate in front of the roller
Solution Approach 1:
Instead of making the entire roller complex, only localized recessed portions are added to the roller surface. This minimal modification maintains overall structural simplicity while providing the necessary functionality to handle thick carrier tapes without stagnation.
3Device complexity
If no auxiliary conveyance mechanism is used, then the device is simple, but work burden and work time increase for loading thick carrier tapes
Solution Approach 1:
The recessed portions on the roller enable the carrier tape to be self-conveyed into the proper position. The tape's own thickness interacts with the recessed portions to create the necessary propulsion, eliminating the need for external assistance mechanisms and reducing both device complexity and loading time.

AI summary
A tape conveyance assistance device assists a carrier tape, which is formed by bonding a cover tape to an upper surface side of a base tape provided with a cavity in which a component is accommodated at a constant pitch, to be conveyed along a conveyance path of a tape feeder in a loading process of loading the carrier tape on the tape feeder, the tape conveyance assistance device includes a roller rotatably provided in a state in which the carrier tape is biased to move along the conveyance path, and a recessed portion configured to temporarily accommodate a front end of the carrier tape conveyed along the conveyance path in the loading process is provided on a peripheral surface of the roller.
