Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a mechanical positioning method is used for adhesive applying, then the device complexity is reduced, but the manufacturing precision deteriorates
Solution Approach 1:
The patent replaces the traditional mechanical positioning system with a visual positioning system using cameras and image processing. The detection assembly captures images of the battery cell and adhesive paper, and the visual compensation module calculates position deviations through image analysis, substituting mechanical measurement methods with optical detection to achieve higher precision without increasing mechanical complexity
Solution Approach 2:
The patent uses visual copying through imaging to create a digital representation of the physical positions. The detection assembly creates images of the battery cell and adhesive paper positions, and the visual compensation module works with these copied visual information to calculate deviations and guide correction, enabling precise positioning through information copying rather than direct mechanical measurement
2Manufacturing precision
If visual compensation is implemented to improve adhesive applying precision, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The visual compensation module serves multiple functions: it detects position deviations of both the battery cell and adhesive paper, calculates total deviation values by combining multiple error sources, and generates correction instructions for the adhesive applying mechanism. This multi-functional design consolidates what would otherwise require separate detection and control systems into a single integrated module, reducing overall system complexity while maintaining high precision
Solution Approach 2:
The patent implements a closed-loop feedback system where the detection assembly continuously monitors the positions of the battery cell and adhesive paper, the visual compensation module calculates deviations from target positions, and the adhesive applying mechanism adjusts its position based on the calculated correction values. This feedback mechanism enables automatic compensation for positioning errors, achieving high precision through iterative correction rather than complex mechanical precision

AI summary
The present application relates to an adhesive applying apparatus, an adhesive applying method and a battery processing device. The adhesive applying apparatus includes a workbench, an adhesive applying mechanism, a detection assembly, and a visual compensation module. The detection assembly can detect to obtain current positions of a battery cell and adhesive paper respectively. The visual compensation module can obtain a total deviation value based on a deviation value between the current position of the battery cell and its target position and a deviation value between the current position of the adhesive paper and its target position, and then correct an adhesive applying position of the adhesive applying mechanism based on the total deviation value, so that the adhesive applying mechanism can apply adhesive on the battery cell at the corrected adhesive applying position, thereby effectively improving precision of adhesive applying for the battery cell.
