Movable Crimping Modules for Flexible Flat Cable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crimping devices for flexible printed circuits (FPC) and flexible flat cables (FFC) face inefficiencies due to immovable crimping modules and frame interference with transport carriers, leading to reduced production efficiency and high costs.
Innovation Solution
A crimping device with an upper and lower moving mechanism, allowing the crimping modules to be horizontally synchronized to any position on the flexible flat piece, and a carrier support frame that enables transport without interference, enhancing crimping efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the crimping modules are made fixed and stationary, then the device structure is simple, but the crimping position cannot be adjusted and production efficiency decreases
Solution Approach 1:
The crimping modules are transformed from fixed stationary structures to movable dynamic components. The upper crimping module moves along the guide rail vertically, while the lower crimping module moves horizontally along the X-axis and vertically along the Y-axis. This dynamic capability allows the crimping modules to reach any position on the flexible flat piece, significantly improving crimping efficiency and adaptability.
2Productivity
If the frame is designed with large size to support crimping operations, then the structural stability is ensured, but the transport carrier cannot be moved into the device
Solution Approach 1:
The frame structure is segmented into modular components with distinct functions. The carrier support frame provides a stable base for carrier movement, while separate guide rails and moving mechanisms support the crimping modules. This segmentation allows the carrier to be transported freely on the support frame without interference from the crimping mechanisms, improving transport efficiency while maintaining overall structural stability.
3Adaptability or versatility
If the crimping modules are positioned fixedly, then the device complexity is reduced, but the flexible positioning capability is lost
Solution Approach 1:
The lower crimping module is designed with multi-functional movement capabilities, able to move both horizontally along the X-axis and vertically along the Y-axis. This universal movement capability allows a single module design to handle various crimping positions and orientations on the flexible flat piece, improving adaptability while managing complexity through standardized motion mechanisms.

AI summary
A crimping device includes an upper moving mechanism, a lower moving mechanism located below the upper moving mechanism, an upper crimping module installed on the upper moving mechanism, a lower crimping module located below the upper moving mechanism and installed on the lower moving mechanism, and a carrier support frame for supporting a carrier transported to the crimping device and a flexible flat piece loaded on the carrier. The upper crimping module and the lower crimping module are adapted to crimp a terminal onto the flexible flat piece. The upper moving mechanism and the lower moving mechanism are adapted to horizontally move the upper crimping module and the lower crimping module respectively, so that the upper crimping module and the lower crimping module are synchronously movable to any crimping position on the flexible flat piece.
