Solution Overview
Problem
Existing methods for inspecting the mounting state of components on a board cannot accurately determine if the component is properly pushed into the board, making it difficult to identify mounting failures and their causes in component mounting devices.
Innovation Solution

1Measurement precision
If imaging device inspection method is used to check component mounting, then the component presence can be inspected, but the mounting quality (whether component is pushed into board with proper load) cannot be accurately determined
Solution Approach 1:
The inspection system is segmented into multiple independent detection functions: imaging device for component presence detection and contact detection sensor for mounting quality detection. Each sensor handles a specific aspect of inspection, allowing accurate determination of both component presence and mounting quality without information loss.
Solution Approach 2:
A contact detection sensor is introduced as an intermediary device between the component mounting process and the inspection system. This sensor directly detects whether the component is properly pushed into the board by detecting contact force, providing accurate mounting quality information that complements the imaging device data.
2Ease of operation
If multiple detection result data are stored and analyzed by multiple conditions, then the mounting state analysis capability is improved, but the data processing complexity increases
Solution Approach 1:
The data processing system is designed with multi-functionality to handle various analysis needs. The same storage and processing infrastructure supports multiple analysis conditions (mounting quality, component presence, error patterns) simultaneously, making the system versatile for different inspection requirements without proportionally increasing complexity.
Solution Approach 2:
The system automatically stores, processes, and analyzes detection result data without requiring manual intervention. The processing unit autonomously correlates imaging device and contact detection sensor data, generates mounting state assessments, and identifies errors, making the system easy to operate while managing data processing complexity internally.

AI summary
An analysis device is a device for use for a component mounting device including a pickup member configured to be moved relative to a board by means of a moving device and a contact detection sensor configured to detect that a component picked up by the pickup member is brought into contact with the board to analyze a mounting state of the component mounting device. The analysis device includes a storage device configured to store multiple detection result data relating to detection results obtained by the contact detection sensor when the component is mounted on the board in association with mounting conditions when the detection results are obtained by the contact detection sensor, and an output device configured to count the multiple detection result data stored in the storage device by at least two conditions in the mounting conditions and output the multiple detection result data so counted.
