Solution Overview
Problem
The existing technologies fail to effectively remove pollutants such as spatter from welding jigs during laser welding, leading to compromised welding quality.
Innovation Solution
A welding jig micro-cleaning apparatus is designed with a housing, sandbox, air supply unit, blasting gun, jig fixing portion, and controller, featuring a magnetic unit for fixing the jig, a sliding unit for horizontal movement and rotation, and a sealing portion to prevent secondary pollution, allowing for efficient removal of pollutants using a micro-blaster.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ultrasonic welding is used to connect electrode tab and electrode lead, then welding is performed, but foreign matter such as spatter is generated and attaches to the welding jig, lowering welding quality
Solution Approach 1:
The patent applies preliminary action by introducing a cleaning apparatus that operates before welding to prevent spatter attachment. The high-pressure air blowing unit blows air toward the welding jig before welding occurs, preventing foreign matter from attaching to the jig surface in advance, thereby maintaining welding quality without compromising manufacturing capability.
2Object-affected harmful factors
If a cleaning apparatus is introduced to remove spatter, then welding quality is improved, but device complexity increases
Solution Approach 1:
The cleaning apparatus is segmented into functionally independent units: a high-pressure air blowing unit for removing spatter, a suction unit for collecting particles, and a control unit. This segmentation allows each component to perform its specific function efficiently while keeping the overall structure manageable and not excessively complex.
Solution Approach 2:
The patent uses air as an intermediary substance to transfer momentum and remove spatter from the welding jig. The high-pressure air blowing unit directs air flow toward the jig, and the air current carries away foreign matter, which is then captured by the suction unit. This intermediary approach simplifies the cleaning mechanism compared to direct mechanical contact methods.
3Productivity
If manual cleaning operation is used, then operation flexibility is maintained, but cleaning efficiency is low
Solution Approach 1:
The cleaning apparatus performs self-service cleaning by automatically detecting the presence of foreign matter on the welding jig and initiating the cleaning process. The control unit coordinates the air blowing and suction operations without requiring manual intervention, thereby significantly improving cleaning efficiency while maintaining ease of operation through automated control.
Solution Approach 2:
The system incorporates feedback mechanisms where the control unit monitors the cleaning process and adjusts operations accordingly. The suction unit detects particles in real-time, and this information feeds back to the control unit, which regulates the air blowing and suction operations to optimize cleaning efficiency while maintaining simple operation.
