Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery cell sorting devices face inefficiencies due to varying grades of cells, leading to underutilized production capacity and resource waste, as some grades exceed or fall short of the rated capacity of palletizing stations.
Innovation Solution
A sorting device with a hierarchical and shared sorting line module assembly that buffers and sorts battery cells, allowing high-proportion grades to be processed efficiently while lower-proportion grades accumulate until they meet the palletizing quantity, optimizing production capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If each grade of battery cells has a dedicated palletizing station, then sorting precision is improved, but device complexity and resource waste increase due to underutilized production capacity
Solution Approach 1:
The patent implements a shared palletizing station that serves multiple sorting lines by introducing a grade switching mechanism. This allows a single palletizing station to handle different battery cell grades dynamically, replacing the need for dedicated palletizing stations for each grade. The switching mechanism enables the station to adapt its configuration based on the current sorting requirements, achieving multi-functionality while reducing overall system complexity and resource waste.
2Adaptability or versatility
If multiple palletizing stations are configured for different grades, then sorting capability is improved, but productivity decreases due to underutilized production capacity
Solution Approach 1:
The patent merges multiple dedicated palletizing stations into a single shared palletizing station that serves multiple sorting lines. By combining these resources and introducing a grade switching mechanism, the system achieves versatile sorting capability for different battery cell grades while improving production capacity utilization. The shared station consolidates resources that would otherwise sit underutilized, allowing better load balancing across the sorting system.
3Speed
If battery cells are sorted and palletized immediately, then processing speed is improved, but loss of time occurs when grades do not meet preset palletizing quantities
Solution Approach 1:
The patent implements preliminary buffering action for battery cell grades that do not immediately meet palletizing quantity requirements. Instead of discarding or delaying these cells, the system pre-stores them in a buffer zone and continuously monitors their accumulation. When the buffered quantity reaches the preset palletizing threshold, the system automatically triggers the palletizing process. This preliminary buffering action eliminates idle waiting time and maintains continuous processing flow.
Solution Approach 2:
The system employs feedback mechanisms to monitor the quantity of buffered battery cells in real-time. When the buffered quantity reaches the preset palletizing quantity, the feedback signal automatically activates the palletizing operation. This closed-loop control ensures that palletizing is triggered at the optimal moment, preventing both premature palletizing (which would leave capacity unused) and excessive waiting (which would reduce productivity).

AI summary
The present application discloses a sorting device, a shared sorting line module assembly and a hierarchical sorting line module assembly, where the shared sorting line module assembly is connected to the hierarchical sorting line module assembly; where the hierarchical sorting line module assembly is configured to receive upstream mixed incoming objects and is capable of sorting out at most N grades of graded objects from the mixed incoming objects, where the mixed incoming objects includes M grades of graded objects, M is an integer and not less than N+2, and N is an integer not less than 1; and the shared sorting line module assembly is configured to receive and buffer various grades of graded objects, and is capable of sorting out any grade of graded objects with a buffered quantity that reaches a preset palletizing quantity. In this way, the top N grades of graded objects with high proportions can be sorted and palletized through the hierarchical sorting line module assembly, and the graded objects entering the shared sorting line module assembly wait for sorting in the case that the quantity does not reach the preset palletizing quantity, so as to avoid the situation that the production capacity of the sorting device is difficult to be fully utilized due to failure to meet the quantity for a single palletizing.
