Electronic Component Mounting Device Clip Cover Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component mounting devices require large nozzles or chucks to efficiently position and load frame members, leading to inefficiencies and space constraints when trying to cover electronic components with shield covers.
Innovation Solution
An electronic component mounting device that uses a clip and cover member with an engaging portion, allowing the device to pick up and position multiple engaged members and cover components efficiently, replacing the need for a frame member and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large nozzle or chuck is used to pick up the frame member, then the frame member can be positioned and loaded efficiently, but the electronic component mounting device occupies more space and loses efficiency
Solution Approach 1:
The invention divides the mounting process into two separate stages: first mounting the electronic component, then separately positioning and attaching the cover component. This segmentation allows each component to be handled with appropriately sized tools, eliminating the need for large nozzles or chucks while maintaining high mounting efficiency.
Solution Approach 2:
The electronic component is mounted first as a preliminary action, establishing a reference position on the board. Subsequently, the cover component is positioned relative to this pre-mounted component, eliminating the need for large positioning tools while ensuring accurate placement.
2Reliability
If one frame member is installed to surround the electronic component, then the component is covered and protected, but the device requires more space and becomes less efficient
Solution Approach 1:
The invention extracts the cover component from the traditional frame member structure. Instead of using a large frame member that surrounds the electronic component, a smaller cover component is used that can be precisely positioned and attached only where needed, reducing space occupation while maintaining protective coverage.
Solution Approach 2:
The invention transitions from a two-dimensional frame member that surrounds the component to a three-dimensional cover component that attaches from above. This dimensional change allows for more compact device design while maintaining effective component coverage and protection.
3Area of stationary object
If multiple engaged members are positioned and loaded, then space is saved and efficiency is improved, but the positioning and loading process becomes more complex
Solution Approach 1:
The cover component is designed with self-aligning features including positioning protrusions that fit into corresponding recesses on the board, and engaging portions that automatically align with reference marks. This self-service mechanism simplifies the positioning and loading process despite handling multiple components, as the components guide themselves into correct positions.

AI summary
An electronic component mounting device, including: a board conveyance device which conveys and positions a board on which an electronic component is mounted; a mounting device which positions and mounts the electronic component to a mounting position of the board; a loading device which picks up multiple engaged members (clips), and positions and loads the engaged members to a loading position of the board; and a placing device which picks up a cover component that covers the mounted electronic component and that is provided with an engaging portion at a predetermined position, and positions and places the cover component to a position such that the engaging portion corresponds to the engaged member.
