Component Supply Device Cover Tape Peeling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component supply devices face challenges in stabilizing the posture of components after peeling off the cover tape due to shock, vibration, and static electricity, while also struggling with reliable tape peeling mechanisms that impede tape feeding.
Innovation Solution
A component supply device with a transporter and peeler mechanism that peels off the cover tape via an opening portion with a variable open state, allowing reliable peeling and stabilization of the component posture through controlled air ejection and roller mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the opening portion is kept large to allow the peeler to capture the cover tape, then the peeling function is improved, but the component posture becomes unstable due to shock and vibration
Solution Approach 1:
The cover is designed to dynamically change its state between open and closed positions based on the operational phase. During peeling operation, the cover is open to allow cover tape capture. After peeling, the cover closes to stabilize the component posture. This dynamic adjustment resolves the contradiction between needing a large opening for peeling and needing a closed state for stability.
2Stability of the object's composition
If the opening portion is made small to stabilize component posture, then the stability is improved, but the peeler cannot reliably capture the cover tape
Solution Approach 1:
The cover transitions from a static small opening to a dynamic structure that opens during peeling operations. This allows the system to have a small opening for stability during transport and pickup, while reliably opening to allow cover tape capture during peeling operations.
3Ease of operation
If a cover tape feeding mechanism is provided, then the cover tape can be fed smoothly, but the mechanism becomes complex and may impede tape feeding
Solution Approach 1:
The cover tape feeding function is extracted from the main carrier tape feeding mechanism. The cover tape is fed through a separate opening portion that is independent of the carrier tape path. This extraction allows the cover tape to be fed smoothly without interfering with the carrier tape feeding mechanism, while avoiding the complexity of integrating both functions into a single mechanism.

AI summary
There is provided a component supply device for supplying a component to a component mounter, including: a transporter that transports a carrier tape in which the component is stored and of which an upper surface is sealed with a cover tape, along a transport path; a peeler that peels off the cover tape from the carrier tape via an opening portion disposed above the transport path; and a cover that makes an open state of the opening portion variable. The cover sets the open state of the opening portion to be any of a first open state allowing the peeler to capture the cover tape and a second open state where an opening size of the opening portion is smaller than that of the first open state and passage of the cover tape peeled off from the carrier tape is not impeded.
