Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deburring of printed circuit boards is manually intensive, costly, and poses health risks due to loose shavings.
Innovation Solution
An automated apparatus with a platform, guiding rails, deburring units, and a driving unit that moves boards between loading/unloading and processing zones, allowing for frictional contact with deburring members and efficient shaving collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual deburring is performed by operators, then deburring processing can be completed, but processing cost is high and processing time is long
Solution Approach 1:
The apparatus enables automatic deburring operation where the carrying unit autonomously moves boards through the processing system. The driving unit automatically positions boards between deburring members without requiring manual intervention for each board, allowing the system to service itself during the deburring process.
Solution Approach 2:
The deburring apparatus is divided into distinct functional modules: carrying unit for board transport, driving unit for positioning, deburring unit with multiple deburring members for actual processing, and guiding rail units for movement control. This segmentation allows each component to perform its specific function efficiently while maintaining overall system simplicity.
2Object-affected harmful factors
If manual deburring is performed, then boards can be deburred, but shavings generated pose health dangers
Solution Approach 1:
The apparatus converts the harmful loose shavings generated during deburring into contained material by guiding them into a collection container. The guiding rail units and platform structure work together to channel shavings away from the operating environment and into a designated collection area, transforming a health hazard into a manageable byproduct.
3Ease of manufacture
If automated deburring is implemented, then processing cost is reduced, but device complexity increases
Solution Approach 1:
The carrying unit serves multiple functions: it transports boards to the processing zone, positions boards during deburring, and facilitates board removal. The driving unit both moves the carrying unit between zones and positions boards within the processing zone. This multi-functionality reduces the need for separate components, simplifying the overall automated system while maintaining cost efficiency.
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
Reduces deburring time and operational costs, enabling single-operator operation while effectively containing and collecting shavings, thus enhancing safety and efficiency.
Implementation Method 1
the deburring members of the deburring unit are in frictional contact with the boards, thereby deburring the boards

AI summary
An apparatus for deburring boards includes a platform, on which first and second guiding rail units perpendicular to each other are fixed, a deburring unit mounted on the first guiding rail unit, a carrying unit adapted for carrying the boards and mounted movably on the second guiding rail unit perpendicular to the first guiding rail unit, and a driving unit disposed on the platform and operable to drive the carrying unit to move between a loading/unloading zone, where the carrying unit is spaced apart from the deburring unit, and a processing zone, where the carrying unit is disposed between opposite deburring members of the deburring unit so that opposite deburred edges of each board contact respectively the deburring members. The driving unit further drives the carrying unit to move back and forth within the processing zone a predetermined number of times, thereby deburring the boards.
