1Object-affected harmful factors
If ionic wind is emitted to remove static electricity from battery cells, then static electricity is removed, but the extraction process becomes slow and less efficient
Solution Approach 1:
The patent replaces the electrical method (ionic wind) with a mechanical method (vibration). The vibration unit generates mechanical vibrations that physically detach battery cells from the suction unit, substituting the electrical field-based ionic wind system with a mechanical oscillation system that achieves faster cell extraction.
Solution Approach 2:
The patent directly applies mechanical vibration to solve the problem. The vibration unit generates vibrations that propagate to the battery cells, causing them to detach from the suction unit through vibrational energy. This mechanical vibration approach achieves both static electricity removal and rapid extraction simultaneously.
2Speed
If a cylinder unit with hydraulic or electrical power is added to strike battery cells, then cells are separated quickly, but device complexity and energy consumption increase
Solution Approach 1:
The patent merges the vibration generation function directly into the suction unit structure. The vibration unit is integrated with the suction unit, eliminating the need for separate cylinder units and their associated hydraulic or electrical power systems. This integration achieves quick cell separation while maintaining simple device structure and low energy consumption.
Solution Approach 2:
The suction unit itself serves dual functions: both suctioning battery cells and generating vibrations for cell separation. The vibration unit, when activated, causes the suction unit to vibrate, which in turn vibrates the attached battery cells, enabling self-service operation without external hydraulic or electrical power systems.
3Reliability
If residual pressure remains in the suction unit, then battery cells are held firmly, but deintercalation becomes slow and inefficient
Solution Approach 1:
The patent uses mechanical vibration to overcome the holding effect of residual pressure. The vibration unit generates vibrations that disrupt the static attachment between battery cells and the suction unit, enabling rapid deintercalation even when residual pressure maintains firm cell holding during normal operation.
