Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for positioning a clamping device in a bonding process are inefficient, requiring manual correction and lacking precise assistance for machine operators, which can lead to misalignment and potential vibration or collision issues during the bonding process.
Innovation Solution
A method that includes an initialization routine to capture and store reference markings of the bonding product and clamping device, allowing for precise determination and storage of the clamping finger reference position, and a takeover routine that uses camera-based image analysis to iteratively correct misalignment, enabling reliable and accurate positioning of the clamping device using a computer-assisted approach.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual positioning and correction of the clamping device is used, then the machine operator can perform the bonding process, but the setup process is time-consuming and prone to misalignment
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated optical measurement system. A camera captures images of the clamping device and bonding product, and a computer calculates the clamping finger reference position based on these images, eliminating the need for manual measurement and positioning by the machine operator.
Solution Approach 2:
The patent creates a digital reference model of the clamping device and bonding product based on captured images. The computer stores the clamping finger reference position as digital data, which can be reused for subsequent bonding processes, eliminating repeated manual positioning efforts.
2Reliability
If the clamping device is positioned without precise reference, then the setup is faster, but misalignment causes vibration and collision risks during bonding
Solution Approach 1:
The patent replaces complex manual positioning procedures with a simplified automated system. The camera and computer automatically calculate the correct clamping finger reference position, reducing the complexity of operator actions while improving reliability through precise digital measurement and calculation.
Solution Approach 2:
The system captures images of the actual clamping device position, compares it with the reference model, and calculates the correct reference position based on this feedback. This closed-loop approach ensures accurate positioning while keeping the system relatively simple.
3Measurement precision
If an initialization routine with reference marking capture is implemented, then precise clamping finger reference position can be determined, but the setup procedure becomes more complex
Solution Approach 1:
The patent replaces complex manual measurement procedures with automated optical capture. The camera automatically captures images of reference markings on the bonding product and clamping device, and the computer automatically processes these images to determine the clamping finger reference position, reducing the complexity of manual operations.
Solution Approach 2:
The system creates digital copies of the reference markings through image capture and stores the calculated reference position as digital data. This digital reference can be reused without repeating the complex measurement process, maintaining high precision while simplifying subsequent setups.

AI summary
A method for securing a bonding product in a working region of a bonder via a clamping device. The bonding product and the clamping device are positioned in the working region of the bonder and a partial characteristic contour is captured to determine the position of the bonding product in the working region. The previously set clamping position of the clamping fingers is captured via a camera and a clamping position is calculated. A current position and orientation of clamping fingers and a new misalignment of the clamping fingers is calculated and displayed until the current position and orientation of the clamping fingers corresponds to a clamping finger reference position.
