Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting machines, the deviation of electronic components during feeding is influenced by both magnetism and shape, and current methods rely on operator experience to adjust supply conditions, leading to inconsistent feeding.
Innovation Solution
A component mounting system with a tape-type supply feeder that includes a storage section for shape data and a control section to determine and adjust the speed or acceleration of component feeding based on the electronic component's shape, ensuring accurate supply positioning.

Engineering Contradiction Analysis
1Reliability
If the supply condition is changed by reducing feeding speed based on magnetism detection, then electronic components without magnetism can be made difficult to deviate, but the deviation cannot be fully prevented for components with specific shapes that are prone to deviation regardless of magnetism
Solution Approach 1:
The system changes the supply conditions (feeding speed, acceleration) based on the detected shape parameters of the electronic component. The control section automatically adjusts these parameters according to the component shape data stored in the storage section, eliminating the need for operator judgment and experience-based adjustments.
Solution Approach 2:
The patent replaces the manual operator judgment and adjustment process with an automated detection and control system. The detection section identifies component shapes, and the control section automatically determines supply conditions, substituting human operational skills with automated sensing and control mechanisms.
2Manufacturing precision
If the feeding speed is reduced for non-magnetic components, then deviation is reduced, but this approach does not account for shape-related deviation issues that persist regardless of speed reduction
Solution Approach 1:
The system performs preliminary detection of the electronic component's shape characteristics before the feeding process begins. The detection section captures shape data, and the control section pre-determines the appropriate supply conditions based on this data, allowing for precise control throughout the subsequent feeding operation.
Solution Approach 2:
The system uses detection section feedback to continuously monitor component shape characteristics and adjusts supply conditions accordingly. The control section receives shape data from the detection section and automatically modifies feeding parameters to optimize positioning accuracy for each component type.
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
The system effectively reduces component deviation by tailoring the feeding speed or acceleration to the specific shape of the electronic component, ensuring consistent and appropriate supply, independent of operator skill.
Implementation Method 1
a magnet is disposed below the tape, and as for an electronic component having magnetism, the deviation of the electronic component (for example, a protrusion from a cavity provided in the tape for accommodating the electronic component) is prevented when the electronic component is fed out by the magnet

AI summary
A component mounting system includes: a tape-type component supply feeder detachably attached to a component mounting machine for mounting an electronic component on a board, having a component feeding mechanism feeding out the electronic component to be accommodated in a tape to a supply position, and configured to supply the electronic component fed to the supply position to the component mounting machine; a storage section configured to store shape data of the electronic component; and a control section configured to determine a speed from a time when the electronic component is fed to the supply position to a time when the electronic component is stopped by the component feeding mechanism, based on the shape data of the electronic component.
