Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scrap discharge methods for laser notching machines are inefficient, often causing scrap to be blown over the electrode plate, requiring sensitive adjustments of the discharge hole size and position, and can lead to tab crumpling and defects due to high sensitivity to electrode plate speed.
Innovation Solution
A conveyor system with a suction part and scrap discharge hole configured to efficiently manage scrap discharge through a conveyor belt and vacuum sectors, reducing the need for speed-dependent adjustments and preventing tab crumpling by controlled air suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional scrap discharge method with a stand and scrap discharge hole is used, then the structure is simple, but the scrap discharge efficiency is low and scrap is often blown over the electrode plate
Solution Approach 1:
The conveyor belt is divided into multiple suction zones with different vacuum pressures along the transfer direction. The suction part includes a first suction zone near the laser notching position with higher vacuum pressure to quickly capture scrap, and a second suction zone further away with lower vacuum pressure to gently transport scrap, preventing it from being blown over the electrode plate while maintaining high discharge efficiency
Solution Approach 2:
The invention uses a vacuum suction system with a suction part connected to a vacuum source. The suction part includes suction holes communicating with the inner space of the conveyor body, creating a controlled airflow field that efficiently captures and transports scrap without causing it to scatter or blow over the electrode plate
2Productivity
If the suction force is increased to improve scrap discharge efficiency, then scrap is discharged more effectively, but tabs may be sucked into the discharge hole and crumpled
Solution Approach 1:
Different regions of the suction part have different vacuum pressure characteristics. The first suction zone has higher vacuum pressure for effective scrap capture, while the second suction zone has lower vacuum pressure to gently transport already-captured scrap. This spatial variation in suction intensity ensures tabs are not crumpled during transport
Solution Approach 2:
The suction holes are positioned and sized to create a controlled suction field that preferentially captures lightweight scrap particles before they can be blown away, while the gradual pressure gradient prevents excessive suction force from acting on the tabs, thus preventing tab crumpling before discharge
3Manufacturing precision
If the scrap discharge hole size and position are adjusted to accommodate varying electrode plate speeds, then discharge accuracy is improved, but the system becomes highly sensitive to speed changes and requires frequent adjustments
Solution Approach 1:
The conveyor belt moves continuously at the same speed as the electrode plate, creating a dynamic synchronization that maintains optimal relative positioning between the suction holes and the scrap generation point. This dynamic adaptation eliminates the need for manual adjustments when electrode plate speed changes
Solution Approach 2:
The suction part with its distributed suction holes serves multiple functions: capturing scrap at the laser notching position, transporting it along the conveyor belt, and discharging it through the scrap discharge hole. This multi-functional design works effectively across a range of electrode plate speeds without requiring parameter adjustments
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures efficient scrap discharge without tab crumpling, reduces the need for frequent adjustments, and maintains productivity by minimizing disruptions in the tab forming process.
Implementation Method 1
a vacuum sector provided with a plurality of vacuum holes communicating from an inner space of the conveyor body to a lower surface of the conveyor body
Implementation Method 2
scrap resulting from forming a tab in an electrode plate passing through the conveyor is sucked in the vacuum sector by the vacuum pressure so as to be adsorbed to a lower portion of the conveyor
Implementation Method 3
the scrap which has passed the vacuum sector is released from the conveyor belt downwards, and when the scrap may pass above the scrap discharge duct, air pressure capable of sucking the scrap is applied to the scrap discharge hole inside the scrap discharge duct by the air suction device
