Automatic Wire Pickup for Dual-Interface Card Antennas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing dual-interface cards with built-in antennas suffer from low yield, high material waste, and low production efficiency due to manual antenna pickup and the difficulty in controlling the piercing depth of wire pickup clamps, which can damage the cards and antennas.
Innovation Solution
An automatic wire pickup method and device that uses an optical scanner to locate the antenna ends and a heated wire pickup clamp to melt and separate the antennas from the card, allowing for precise and efficient pickup without damaging the cards or antennas, improving yield and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual pickup method is used for antenna end, then operation flexibility is maintained, but production efficiency is low and yield is reduced
Solution Approach 1:
The patent replaces the manual mechanical pickup operation with an automated wire pickup clamp system controlled by a control unit. The clamp is positioned and actuated automatically to pick up antenna ends, eliminating manual labor while maintaining precise control over the pickup process.
Solution Approach 2:
The system uses an optical scanner to automatically detect and locate antenna ends, then the control unit automatically positions and actuates the wire pickup clamp based on the detected positions. The system serves itself by using its own detection capability to guide its own pickup operation without external intervention.
2Productivity
If wire pickup clamp is used to automate antenna pickup, then production efficiency is improved, but piercing depth control is difficult causing card damage
Solution Approach 1:
The patent incorporates an optical scanner that detects the position of antenna ends and provides feedback to the control unit. The control unit uses this feedback information to automatically adjust the positioning and piercing depth of the wire pickup clamp, ensuring precise control and preventing card damage while maintaining automated operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The automatic method increases production yield, reduces material waste, and enhances production efficiency by accurately and automatically picking up the antennas, ensuring they stand on the card without damage.
Implementation Method 1
an optical scanner scans the antenna end of the built-in antenna in the chip slot for obtaining its location
Implementation Method 2
The wire pickup clamp can be heated before wire pickup operation. The wire pickup clamp can melt the card portion beside the antenna end for separating the antenna end from the card
Implementation Method 3
The wire pickup clamp can melt the card portion beside the antenna end for separating the antenna end from the card

AI summary
Disclosed are an automatic wire pickup method for the built-in antenna of dual-interface cards and device thereof. The method comprises: S1: a card is placed on a delivery mechanism so that the antenna ends of the card are substantially perpendicular to the open-close direction of a wire pickup clamp; S2: the antenna ends are scanned with OCR so as to form location data of the antenna ends; S3: the preheated wire pickup clamp is controlled to perform wire pickup operation by a main control system according to the location data. The wire pickup clamp melts the card portion beside the antenna ends so that the antenna ends are separated from the card, and then the wire pickup clamp clamps and lifts the antenna ends so that the antenna ends stands on the card. The device includes a frame (1), a main control system mounted on the frame (1), a delivery mechanism (2), an OCR scanning group (3) and a wire pickup mechanism (4) which are mounted on the frame (1) and connected to the main control system respectively. The beneficial effects are avoiding card damage during wire pickup, improving yield, reducing material waste and also improving production efficiency.
