Carrier Tape Discharge Duct Neutralization in Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The component tape in electronic component mounting devices becomes charged with static electricity during operation, causing the used carrier tape to stick to the discharge duct walls, leading to clogging and interruptions in the manufacturing process.
Innovation Solution
Incorporating a static charge elimination member, such as a brush or cord, within the discharge duct or tape feeder to neutralize static charges on the used carrier tape as it is collected, preventing attraction to the duct walls and ensuring smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a static charge elimination brush is disposed at the tape introduction opening to eliminate static charge on the fed component tape, then static charge on the introduced tape is reduced, but static charge is generated again at the component supply position due to cover tape peeling, and the used carrier tape still sticks to the discharge duct wall
Solution Approach 1:
The invention extracts the static charge elimination function from a single location (introduction opening) and applies it at multiple locations: both the introduction opening and the discharge duct. This ensures that static charge is eliminated at the source (introduction) and also addressed where it causes problems (discharge duct wall sticking).
Solution Approach 2:
The invention introduces a second static charge elimination brush as an intermediary device in the discharge duct to neutralize static charge on the used carrier tape before it contacts the duct wall. This intermediary brush prevents the harmful effect of sticking without interfering with the component feeding process.
2Productivity
If the used carrier tape is collected in a collection box through a discharge duct, then the used tape is disposed of, but the used carrier tape sticks to the discharge duct wall due to static electricity and adhesive, causing clogging and requiring machine stoppage for removal
Solution Approach 1:
The invention applies preliminary anti-action by placing a static charge elimination brush in the discharge duct upstream of the collection box. This brush preemptively neutralizes static charge on the used carrier tape before it can stick to the duct wall, preventing the clogging problem before it occurs.
Solution Approach 2:
The static charge elimination brush performs preliminary action by eliminating static charge on the used carrier tape as it passes through the discharge duct, before the tape reaches the collection box. This preliminary charge elimination prevents subsequent sticking and clogging issues.
3Reliability
If the used carrier tape sticks to the discharge duct wall, then the tape cannot be properly collected, but removing the stuck tape requires stopping the component mounting machine, delaying manufacturing
Solution Approach 1:
The static charge elimination brush in the discharge duct performs preliminary anti-action by neutralizing static charge on the used carrier tape before it can stick to the duct wall. This prevents the situation where tape removal would require machine stoppage, thereby eliminating time loss.
Solution Approach 2:
The invention converts the harmful static charge that causes sticking into a beneficial neutralization process. By placing the static charge elimination brush in the discharge duct, the system actively neutralizes the static charge that would otherwise cause clogging and production delays.
