Split Welding Head for Soldering Near Preset PCB Solder Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing welding heads with V-shaped positioning grooves often interfere with raised preset solder points on circuit boards, preventing successful wire soldering when the solder point is adjacent to the welding position.
Innovation Solution
A dual-part welding head with movable first and second welding ends, where one end abuts the top and the other end abuts the side of the wire, allowing for precise positioning and avoiding contact with the preset solder point, while being connected to a power supply to generate heat for welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a monolithic welding head with V-shaped positioning groove is used, then the wire positioning is simple and the structure is compact, but the welding head bottom touches the preset solder point when the solder point is adjacent to the welding position, preventing successful soldering
Solution Approach 1:
The welding head is divided into a first welding head part and a second welding head part that can move relative to each other. This segmentation allows the welding head to adapt its shape during operation, enabling successful welding even when preset solder points are adjacent to the welding position, thereby resolving the contradiction between structural simplicity and welding reliability.
Solution Approach 2:
The welding head incorporates dynamic movement capability where the second welding head part can move relative to the first welding head part. This dynamic adjustment allows the welding head to maintain optimal contact with the wire while avoiding interference with adjacent preset solder points, improving welding success rate without significantly increasing structural complexity.
2Stability of the object's composition
If the welding head bottom contacts the preset solder point, then the welding head provides stable support, but the wire cannot be soldered due to interference with the solder point
Solution Approach 1:
The welding head uses dynamic movement of the second welding head part relative to the first to maintain stability during welding. The system can adjust its configuration to provide stable support through the first welding head part while the second part moves to avoid interfering with preset solder points, thus maintaining both stability and ease of operation.
3Device complexity
If a fixed monolithic welding head is used, then the device structure is simple, but it cannot adapt to different wire sizes and positions
Solution Approach 1:
The welding head incorporates dynamic movement capability where the second welding head part can move relative to the first welding head part. This dynamic adjustment enables the welding head to adapt to different wire sizes and positions while maintaining a relatively simple overall structure, resolving the contradiction between structural simplicity and adaptability.

AI summary
A welding head includes a first welding head part having a first welding end adapted to contact a welded member, and a second welding head part having a second welding end adapted to contact the welded member. The first welding head part and the second welding head part are arranged side by side in a horizontal direction and are movable relative to each other in a vertical direction. The first and second welding head parts are sized and oriented such that, when welding the welded member, a bottom surface of one of the first welding end or the second welding end abuts a top side of the welded member, and a side surface of the other of the first welding end or the second welding end abuts one side of the welded member.
