Pressing-Track Feeder for Damage-Free Electrode Assembly Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feeding devices for loading electrode assemblies into battery cases often cause damage, leading to low yield and production efficiency due to concentrated contact and force, which can tear separators and compromise the integrity of the assembly.
Innovation Solution
A feeding device with a pressing unit featuring a pressing member that moves cyclically along a closed track with a large surface contact area and dispersed force, utilizing a buffer layer and rotating mechanism to minimize damage, and includes a conversion mechanism using a Reuleaux triangle cam to facilitate smooth material loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional feeder with a single auger is used, then the structure is simple, but it cannot handle multiple types of supplemental feed simultaneously
Solution Approach 1:
The feeder is divided into multiple independent augers (first auger, second auger, third auger) that can operate simultaneously to handle different types of supplemental feed. Each auger can be independently controlled to deliver specific feed types to the mixing chamber, enabling multi-type feed handling while maintaining modular simplicity
Solution Approach 2:
The mixing chamber serves multiple functions by receiving and mixing pellets with different types of supplemental feed from multiple augers. The single mixing chamber design allows it to handle various feed combinations (molasses, fat, oil, etc.) universally, achieving multi-functionality without proportionally increasing structural complexity
2Ease of operation
If a single auger delivers all supplemental feed, then the device complexity is low, but the ability to control individual feed delivery is poor
Solution Approach 1:
The supplemental feed delivery system is segmented into multiple dedicated augers, where each auger is responsible for delivering a specific type of supplemental feed. This segmentation enables independent control of each feed type's delivery rate and timing, improving operational control while keeping each individual auger component simple and manageable
3Manufacturing precision
If supplemental feed is added without pre-mixing, then the process is simple, but clumping occurs and mixing is insufficient
Solution Approach 1:
The system performs preliminary action by delivering multiple types of supplemental feed simultaneously into the mixing chamber before they reach the pelleting die. The feeds are pre-mixed in the chamber with pellets, ensuring uniform distribution and preventing clumping during the high-speed pelleting process, thereby improving mixing precision
4Productivity
If the feeder runs continuously, then productivity is high, but feed bridging and hang-up occur in the hopper
Solution Approach 1:
The feed delivery system employs periodic action through reciprocating motion of the augers, which create pulsating feed flow patterns. This periodic movement prevents continuous static loading that causes bridging, while maintaining overall continuous production. The reciprocating augers periodically dislodge and redistribute feed in the hopper, preventing hang-up and ensuring consistent feed flow during continuous operation

AI summary
Embodiments of the present application provide a feeding device for loading a material into a container, which relates to the technical field of product assembly. The feeding device is configured to load a material into a container having an opening. The feeding device includes a pressing unit. The pressing unit includes a pressing member having a pressing plane, and a driving member configured to drive the pressing member to move cyclically along a closed track. The closed track includes a first planar track segment, and when the pressing member moves along the first planar track segment, the pressing plane forms surface contact with the material and keeps extending in a material loading direction, the material loading direction being a movement direction of the material relative to the case. The feeding device can reduce damage to the material during a feeding process.
