Nested Cassette Structure for Coreless Tape Roll Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing component mounting devices face challenges in addressing the increase in size of the roll body due to insufficient strength and rigidity of the housing device, particularly when a carrier tape is wound in a disc shape without a core.
Innovation Solution
A component mounting device is designed with a housing cassette and receiving cassette that allow for the roll body of the carrier tape to be housed and easily managed, featuring a front opening for insertion and removal, and a shutter mechanism to ensure secure handling and supply of the tape to the mounting head, enabling continuous component supply without interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the carrier tape is wound in a disc shape without a core to form a roll body, then the transportation and storage are simplified, but the housing device becomes insufficient in strength and rigidity to address increase in size of the roll body
Solution Approach 1:
The housing cassette is inserted into the receiving cassette, creating a nested structure where the smaller housing cassette fits within the larger receiving cassette. This nested design provides structural support and rigidity to the overall system while maintaining the coreless roll body configuration for easy transportation and storage.
Solution Approach 2:
The housing device is divided into two separate cassettes: the housing cassette for holding the roll body and the receiving cassette for receiving the housing cassette. This segmentation allows each component to be optimized independently - the housing cassette can be compact for easy storage while the receiving cassette provides the necessary structural strength and rigidity.
2Ease of operation
If the housing device structure is simplified for easy operation, then the ease of operation is improved, but the structural strength and rigidity are insufficient to support larger roll bodies
Solution Approach 1:
The nested cassette structure allows for simple insertion and removal operations while maintaining structural integrity. The housing cassette with opening can be easily inserted into and removed from the receiving cassette, providing ease of operation, while the combined nested structure delivers the necessary strength and rigidity to support larger roll bodies.

AI summary
A component mounting device of the present disclosure is provided with a tape feeder and a mounting head, the component mounting device including: housing cassette (22B) that stores a roll body of a carrier tape and allows the roll body to be taken in and out through an opening; and receiving cassette (22A) that houses roll body (RT) of carrier tape (CT) and allows roll body (RT) to be taken in and out through an opening, and that stores roll body (RT) supplied from housing cassette (22B) equipped on housing cassette attaching unit (39). The tape feeder draws carrier tape (CT) from roll body (RT) of receiving cassette (22A) equipped on receiving cassette attaching unit (38) to supply a component to the mounting head, and draws carrier tape (CT) from roll body (RT) of housing cassette (22B) equipped on housing cassette attaching unit (39) following carrier tape (CT) to supply the component to the mounting head.
