Laser Engraving Workpiece Separation With Switchable Forks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional transport mechanisms in laser engraving machines generate excessive friction on the bottom workpiece due to the blocking method used for separating stacked workpieces, necessitating additional positioning processes.
Innovation Solution
A separating structure with forks that switch between standby and detached positions to separate the bottom workpiece from others, using a driving source and limiting members to move the workpiece to the processing area, reducing friction by propelling upper workpieces away.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stopper is arranged to block workpieces during transportation, then workpieces can be separated sequentially, but excessive friction is generated on the bottom workpiece affecting transport path
Solution Approach 1:
The patent extracts the blocking function from a traditional stopper and implements it through forks that can be selectively positioned. The forks are removed from a continuous blocking state and only engage when needed to separate the bottom workpiece, eliminating continuous friction while maintaining separation capability.
Solution Approach 2:
The blocking mechanism transitions from a static stopper to a dynamic fork system that can move between engaged and disengaged positions. The forks are driven by a driving source to dynamically adjust their position, enabling workpiece separation only when necessary and reducing friction during transport.
2Reliability
If additional positioning processes are arranged for workpieces, then transport path friction is compensated, but device complexity increases
Solution Approach 1:
The forks serve as an intermediary mechanism between the workpieces and the transport system. Instead of adding complex positioning processes to compensate for friction, the forks mediate the separation by providing controlled support to upper workpieces, eliminating the need for additional positioning interventions.
3Object-affected harmful factors
If forks are used to separate workpieces by switching between standby and detached positions, then friction is reduced, but device complexity increases
Solution Approach 1:
The patent combines the separating function with the existing transport mechanism by integrating forks into the conveyor system. The forks share the same driving source and spatial arrangement as the transport belt, merging separation and transport functions into a unified system rather than adding independent complex mechanisms.

AI summary
A separating structure of a laser engraving machine having a base seat, a transport mechanism, and a separating mechanism. The base seat has a waiting area for the workpieces being stacked and a processing area, the transport mechanism includes a driving source and a transfer member electrically connected to the driving source, the transfer member carries the workpieces, the separating mechanism is arranged on the waiting area and has two forks that are capable of switching between a standby position and a detached position. When the forks are located at the standby position, the workpieces are stacked on the transfer member. When the forks are located at the detached position, the forks carry the other workpieces above the workpiece carried by the transfer member, the driving source drives the transfer member to move to the processing area for processing the workpiece.
