Rotating Laser Welding Pusher for Precise Jig Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing push devices for laser welding of secondary batteries, such as lithium secondary batteries, face challenges in precision and convenience due to limitations in their structural design, particularly in adjusting positions and replacing components during the welding process.
Innovation Solution
A push device for laser welding is designed with a main body, a support arm, and a pusher unit, featuring a hinge part, a coupling part, and a guide part, allowing for precise positioning and easy replacement of the pusher unit by rotating the support arm between lift up and lift down positions, with micro-meters for precise adjustment and an air supply system to enhance welding efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the push device uses a fixed structure for welding, then the welding position is stable, but the device cannot be easily adjusted or replaced during the welding process
Solution Approach 1:
The support arm is designed to be rotatable between a lift-up position and a lift-down position, transforming the fixed structure into a dynamic one. This allows the pusher unit to be easily accessed for replacement while maintaining precise positioning during welding operation.
Solution Approach 2:
The push device is divided into separable components: the pusher unit can be detached from the support arm, and the support arm can be rotated independently. This segmentation enables easy replacement of the pusher unit while maintaining the stability of the main body.
2Ease of repair
If the support arm is rotatable for easy maintenance, then component replacement is convenient, but positioning precision may be compromised
Solution Approach 1:
The support arm utilizes its own weight and gravitational force to automatically maintain positioning. When in the lift-down position, gravity keeps the arm stable without requiring additional locking mechanisms, enabling self-positioning that maintains precision while allowing easy replacement.
Solution Approach 2:
The device incorporates a guide part that pre-establishes the correct positioning path for the support arm. This guide structure ensures that when the arm is rotated back to the lift-down position, it automatically returns to the precise welding position without manual adjustment.
3Reliability
If the pusher unit is permanently fixed, then welding stability is maintained, but cleaning and replacement require device disassembly
Solution Approach 1:
The support arm's rotatable design creates a dynamic system where the pusher unit can be easily accessed by rotating the arm to the lift-up position. This eliminates the need for complex disassembly while maintaining welding stability when the arm is in the lift-down position.
Solution Approach 2:
The support arm acts as an intermediary mechanism between the main body and the pusher unit. It provides a simple rotational connection that allows the pusher unit to be easily accessed for cleaning or replacement without requiring disassembly of the entire welding device.

Function Achieved in This Case
The device improves the precision and convenience of the welding process by allowing secure working space for cleaning and replacing components, minimizing position setting deviations, and maintaining welding quality through precise positioning and air management.
Implementation Method 1
a hollow hole through which a laser beam may pass is defined
Implementation Method 2
The support arm is rotatable (e.g. rotated) from a lift down position at which it is coupled to the coupling part and moveable (e.g. moved) to a lift up position at which it is rotated in a direction away from the coupling part
Implementation Method 3
a pusher unit detachably coupled to the other end of the support arm configured to push an adsorption jig configured to adsorb an object to be welded at a welding position

AI summary
Embodiments of the present disclosure relate to a push device for laser welding, including a main body coupled to one side of a welding apparatus and including a hinge part disposed at one side thereof and a coupling part spaced apart from the hinge part, a support arm having one end rotatably coupled to the hinge part and the other end extending in a direction opposed to the hinge part and rotated within a preset angle range, and a pusher unit detachably coupled to the other end of the support arm to push an adsorption jig configured to adsorb an object to be welded at a welding position. The present disclosure may secure a working space when the pusher unit is replaced by including the rotatable support arm of the push device pushing the adsorption jig. Thus, the pusher unit may be easily replaced, and workability of a worker may be enhanced. Also, the present disclosure exhibits an effect of enhancing a welding efficiency by improving a material and a structure of the pusher unit.
