Welding Press Head Assembly for Slag and Laser Leakage Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During battery manufacturing, welding slag splashes out of the welding press head tool, affecting non-welding parts and increasing maintenance costs, and there is also a risk of laser light leakage in laser welding devices, posing safety hazards.
Innovation Solution
The welding press head tool incorporates at least two groups of blocking assemblies arranged between the press plate and press head, with overlapping barriers in the radial and circumferential directions to contain welding slag and laser light, and a dust removal channel to manage slag, while a limiting mechanism ensures stable clamping force in the welding device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a press nozzle is movably connected to the press plate to enable welding operation, then welding flexibility is improved, but welding slag can splash out through the gap between press plate and press nozzle affecting non-welding parts
Solution Approach 1:
The gap between the press plate and press nozzle is segmented into multiple regions by arranging at least two groups of blocking assemblies spaced apart in the radial direction. Each blocking assembly creates individual barrier segments that collectively contain welding slag within the welding channel while preserving the movable connection for welding flexibility.
Solution Approach 2:
Blocking assemblies are introduced as intermediary elements between the press plate and press nozzle. These blocking assemblies act as mediators that allow the gap to exist for welding operation while preventing welding slag from passing through to affect non-welding parts.
2Object-affected harmful factors
If blocking assemblies are arranged to prevent welding slag splash, then protection of non-welding parts is improved, but device structure becomes more complex
Solution Approach 1:
Instead of attempting to completely seal the gap between press plate and press nozzle, the solution uses partial blocking assemblies that provide sufficient containment for welding slag while leaving the structure partially open. This partial action approach prevents excessive complexity while achieving the necessary protection.
Solution Approach 2:
The blocking assemblies are strategically positioned at specific locations within the gap rather than uniformly distributing blocks throughout. This local quality approach places blocking elements only where welding slag containment is most needed, minimizing overall structural complexity while maintaining effective protection.

AI summary
The present application relates to a welding press head tool and a welding device. The welding press head tool includes at least one press head assembly, each including: a press plate provided with a first through hole penetrating the press plate in a first direction; a press head movably connected to one side of the press plate in the first direction and capable of having a first gap with the press plate when the press head moves relative to the press plate, where the press head has a second through hole penetrating the press head in the first direction, and the first through hole and the second through hole are in communication to jointly define a welding channel for providing a welding space; and at least two groups of blocking assemblies arranged between the press plate and the press head.
