Movable Board Imaging Camera for SMT Mounting Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting apparatuses for electronic components on a board require increased structural complexity and cost due to the need for multiple board imaging cameras and associated components, leading to inefficiencies in imaging operations.
Innovation Solution
A mounting apparatus with a head unit featuring a single board imaging camera that is movable along the head arrangement direction, combined with an imaging device moving mechanism, reduces the number of components and structural complexity while enhancing imaging efficiency by minimizing the head unit's movement and allowing for high-speed camera positioning.

Engineering Contradiction Analysis
1Productivity
If multiple board imaging cameras are provided on the head unit, then the imaging range is increased and imaging operation efficiency is improved, but the apparatus structure becomes more complex and cost increases
Solution Approach 1:
The patent makes the single board imaging camera movable along the head arrangement direction (X-axis) through a camera moving device, allowing the camera to dynamically change its position to image different regions of the board. This dynamic positioning replaces the need for multiple fixed cameras, achieving full board coverage while maintaining a simpler structure with fewer components.
2Length of moving object
If multiple board imaging cameras are provided on the head unit, then the total movable range is increased, but the number of components increases resulting in higher cost
Solution Approach 1:
The single board imaging camera is designed to perform multiple functions by moving to different positions along the head arrangement direction. The same camera images various regions of the board at different locations, replacing what would traditionally require multiple dedicated cameras. This multi-functionality reduces the number of components while maintaining the required imaging coverage.
3Area of stationary object
If multiple board imaging cameras are provided on the head unit, then the imaging coverage is improved, but the amount of head unit movement increases reducing efficiency
Solution Approach 1:
The camera is made movable along the head arrangement direction through a dedicated camera moving device, allowing it to access different imaging positions without requiring the entire head unit to move. This dynamic camera positioning enables full board coverage while minimizing head unit movement, as only the camera needs to reposition within the head unit rather than moving the entire heavy head unit assembly.
