Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soldering apparatuses risk performing soldering at incorrect positions due to potential errors in manual entry or fixed reading mechanisms that cannot read target identification information from all locations on a work target.
Innovation Solution
A soldering apparatus with a movable reading portion that reads target identification information, such as barcodes or two-dimensional codes, to associate it with stored position information, ensuring accurate positioning and soldering conditions are applied automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual entry or fixed reading mechanisms are used to input target identification information, then the device complexity is reduced, but the reliability of soldering position accuracy deteriorates due to potential errors in reading or entry
Solution Approach 1:
The reading portion is made movable rather than fixed, allowing it to be positioned dynamically to read target identification information from various locations on the work target. This dynamic capability ensures reliable reading regardless of target orientation or placement, improving soldering position accuracy without requiring overly complex fixed mechanisms
Solution Approach 2:
The system automatically reads and processes target identification information through the movable reading portion, eliminating manual entry requirements. The acquired position information is automatically matched with stored soldering conditions, making the system self-sufficient and improving reliability while maintaining reasonable device complexity
2Measurement precision
If a movable reading portion is implemented to read target identification information from any location, then the reliability of reading accuracy is improved, but the device complexity increases
Solution Approach 1:
The movable reading portion serves multiple functions: it can read target identification information from various locations, orientations, and distances. This single multi-functional component replaces what would otherwise require multiple fixed reading mechanisms, improving reading accuracy while actually reducing overall device complexity
Solution Approach 2:
The reading portion can move in multiple dimensions (X, Y, Z axes and rotation) to access target identification information from any position on the work target. This multi-dimensional mobility ensures comprehensive reading capability without requiring an overly complex mechanism, as the movement follows standard robotic motion principles
3Adaptability or versatility
If teaching data files are stored for each soldering position, then the adaptability to different soldering configurations is improved, but the loss of time for file selection and verification increases
Solution Approach 1:
The system uses target identification information as feedback to automatically determine which teaching data file to use. The reading portion reads the target's identification, the acquiring portion automatically retrieves the corresponding position information from storage, and the process control portion executes the appropriate soldering parameters, eliminating manual file selection and verification time
Solution Approach 2:
Position information and soldering conditions for multiple soldering configurations are pre-stored in the storage portion with associated identification information. This preliminary preparation allows the system to quickly retrieve and execute the correct soldering parameters without time-consuming file selection during actual operation

AI summary
A soldering apparatus is provided with a soldering iron for soldering with a tip, a driving portion for moving the soldering iron, a storage portion that stores position information indicating a soldering position and identification information associated each other, a reading portion that reads target identification information attached to the work target, an acquiring portion that acquires position information in the storage portion matching the target identification information read by the reading portion, and a process control portion for controlling the driving portion and the soldering iron so as to perform soldering at the position indicated by the position information acquired by the acquiring portion.
