Tape Feeder Press with Columnar Protrusions for Component Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component supply devices face issues with components adhering to cover tapes, leading to unreliable supply due to jumping out of storage and contact with release members.
Innovation Solution
A component supply device with a tape feeder and a press featuring columnar protrusions that press the cover tape, preventing adhesion and ensuring components are stored reliably, including a roller with circumferentially arranged protrusions to reduce feeding resistance and an opener to minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If components are stored in storages covered by cover tape, then components are protected from falling out, but components may adhere to the cover tape and jump out when covering is released
Solution Approach 1:
The press applies a downward force to the cover tape in advance before the component extraction process, creating a concave deformation that prevents component adhesion. This preliminary action ensures that when the component is later extracted, it does not stick to the cover tape and jump out, thereby resolving the contradiction between protection and adhesion prevention.
Solution Approach 2:
The press changes the physical state of the cover tape by applying pressure to create a concave deformation. This parameter change in the cover tape's shape and surface properties prevents components from adhering to it, while still maintaining the protective function during storage.
2Ease of operation
If a member is used to release covering with the cover tape, then components can be accessed, but the member may contact and interfere with components
Solution Approach 1:
The press performs the action of separating the component from the cover tape in advance, before the release member acts on the cover tape. This preliminary separation ensures that when the release member opens the cover tape, the component is already clear and will not be contacted or interfered with, thus resolving the contradiction between ease of operation and harmful contact.
3Reliability
If the cover tape is pressed to prevent adhesion, then components are securely stored, but resistance to tape feeding increases
Solution Approach 1:
The press is designed with multiple protrusions that are circumferentially arranged on a roller, segmenting the pressing action into multiple contact points. This segmentation allows the cover tape to be pressed effectively at multiple locations simultaneously, maintaining component storage security while distributing the feeding resistance across multiple points rather than creating a single large resistance barrier.
Solution Approach 2:
The press incorporates a roller that rotates as the tape feeds, making the pressing action dynamic rather than static. The circumferentially arranged protrusions rotate with the roller, continuously applying pressure to the cover tape in a rotating pattern. This dynamic mechanism maintains reliable component storage while allowing smoother tape feeding compared to a fixed pressing structure.
