Mounting Head Image Processing for Reduced Nozzle Image Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The large data amount of image data obtained by imaging multiple nozzle positions in conventional mounting devices poses a challenge due to the inclusion of unnecessary image information, which can overwhelm storage capacity.
Innovation Solution
A mounting device that generates a post-compression image by setting the periphery of the nozzle tip as a target area, replacing pixels outside this area with the same color, and compressing the image in a predetermined format to reduce data volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If images of multiple nozzle positions are always included in the captured image, then complete monitoring of all nozzles is achieved, but the data amount of image data becomes enormous and suppresses storage device capacity
Solution Approach 1:
The patent extracts only the necessary information (nozzle tip periphery areas) from the complete captured image, replacing other areas with pixels of the same color. This extraction principle reduces the image data amount while preserving the critical monitoring information needed for reliability.
Solution Approach 2:
The patent applies local quality by setting specific areas (nozzle tip peripheries) as target areas that require detailed imaging, while other areas are simplified. This allows the system to maintain high monitoring quality where needed while reducing overall data volume.
2Loss of information
If the entire captured image is compressed without replacement, then all image information is preserved, but the compression ratio is insufficient and storage efficiency is reduced
Solution Approach 1:
The patent extracts only the essential nozzle tip periphery regions from the full image before compression. By removing redundant information from non-target areas and replacing those pixels with uniform color, the system achieves better compression ratios while maintaining the critical information needed for monitoring.
Solution Approach 2:
The patent applies partial action by focusing compression and processing efforts only on the target areas (nozzle tip peripheries) rather than the entire image. This selective approach improves storage efficiency without sacrificing the information quality needed for reliable monitoring.

AI summary
A mounting device of the present disclosure is a device that mounts components on a board. The mounting device includes a mounting head including multiple holding bodies configured to hold the components at tips, an imaging section configured to capture a captured image including two or more of the multiple holding bodies, and an image processing section configured to execute post-compression image generation processing of generating a post-compression image by setting an area including a periphery of the tip of at least one holding body in the captured image as a target area, replacing pixels outside the target area in the captured image with pixels of the same color, and compressing a post-replacement image in a predetermined compression format.
