Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component mounting methods face challenges in efficiently mounting components with protruded leads supplied in a fallen-down attitude due to the complexity of changing their attitude to a stand-up position, requiring intricate devices that hinder the compactness and efficiency of the mounting process.
Innovation Solution
An electronic component mounting method and apparatus utilizing a mounting head with a component holder, pusher, and rotator, which includes a suction path for holding components and an attitude changing device to vertically rotate the component holder, allowing the electronic component to be efficiently positioned and inserted into substrate holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a component holding hand with a link mechanism having two arms is used to change the attitude of the insertion component, then the attitude change function is achieved, but the device complexity increases
Solution Approach 1:
The patent extracts the attitude change function from a complex link mechanism and implements it through a simple rotator that rotates the nozzle holder. This separates the suction function (performed by the nozzle) from the attitude change function (performed by the rotator), eliminating the need for complex two-arm link mechanisms while maintaining the ability to change component attitude from fallen-down to stand-up position.
Solution Approach 2:
The mounting head is designed with multi-functionality, integrating component suction, attitude change, and positioning capabilities into a single device. The rotator can rotate the nozzle holder to different angles, allowing the same device to handle components in various attitudes without requiring separate specialized mechanisms for each function.
2Adaptability or versatility
If a complex device is used to change the attitude of the insertion component, then the attitude change capability is improved, but the compactness of the mounting head deteriorates
Solution Approach 1:
The patent implements a nested structure where the rotator is integrated within the nozzle holder assembly. The rotator rotates the nozzle holder around a central axis, allowing the attitude change mechanism to be contained within the compact mounting head volume rather than requiring external link mechanisms. This nested arrangement maintains compactness while providing full attitude change capability.
Solution Approach 2:
The mounting head employs dynamic rotation capability through the rotator, allowing the nozzle holder to be rotated to different angles as needed. This dynamic adjustment mechanism replaces static complex link mechanisms, enabling the mounting head to adapt its configuration within a compact volume while maintaining full attitude change functionality.

AI summary
A position and orientation of an electronic component attitude are recognized, a mounting head is moved above the electronic component, a rotator is horizontally rotated so that a lower surface of the electronic component is oriented in a direction opposite to a pusher, the electronic component of the fallen-down attitude is sucked and held by the nozzle by lowering a component holder, a attitude of the electronic component that is held is changed to a stand-up attitude by vertically rotating the component holder, leads of the electronic component of which the attitude is changed to the stand-up attitude and insertion holes of the substrate into which the leads are inserted are positioned, and the leads are inserted into the insertion holes of the substrate by pushing the electronic component toward the substrate by causing the pusher to abut against an upper surface of the electronic component of the stand-up attitude.
