Component Mounting Device Multi-Claw Pressing Cycle Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing component assembly methods require multiple press-fitting actions for large electronic components, increasing cycle time and decreasing productivity due to the need for separate assembly of central and end sections.
Innovation Solution
A component assembly apparatus equipped with a component transfer device featuring at least two holding claws, which grip and move components to assembly positions on a board, employing a transfer pressing step to grip and press-fit the central section, followed by a pressing step to press-fit the end sections using predetermined positions differing from the gripping locations, thereby reducing the number of press-fitting actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple press-fitting actions are performed separately for central and end sections of large electronic components, then assembly completeness is improved, but cycle time increases and productivity decreases
Solution Approach 1:
The component is divided into multiple pressing regions (central section and end sections), with each region having dedicated pressing holes and pressing pins. This segmentation allows simultaneous pressing of multiple regions in one operation, resolving the contradiction by enabling complete assembly without increasing cycle time.
Solution Approach 2:
Multiple pressing operations that were previously performed sequentially (central section first, then end sections) are merged into a single simultaneous pressing operation. All pressing pins apply force at the same time, achieving complete assembly in one cycle and eliminating the productivity loss from multiple sequential steps.
2Device complexity
If a single component holder is used for all component types, then device complexity is reduced, but assembly efficiency decreases due to multiple repetitive press-fitting steps
Solution Approach 1:
The component holder is designed with multiple pressing holes and pressing pins that can accommodate different component types and sizes. The same holder structure performs multiple functions: holding the component, positioning it, and simultaneously pressing all sections. This maintains device simplicity while enabling efficient multi-region assembly in one operation.
Solution Approach 2:
The pressing mechanism transitions from sequential one-dimensional operation (pressing one section at a time) to parallel multi-dimensional operation (pressing multiple sections simultaneously). Multiple pressing pins operate in different spatial locations at the same time, increasing assembly speed without complicating the holder design.

AI summary
Productivity is improved by reducing a cycle time that is required for assembly as a result of reducing a number of repetitions of a pressing step for assembling each section of a component on a board. The method for assembling a component on a board according to the present invention is configured by a transfer pressing step (Step S102) that assembles a target gripping location of a component 30 by gripping the target gripping location using a component transfer device 19, performing positioning, and applying a pressing force to a board S1 side, and a pressing step (Step S104) that simultaneously assembles each corresponding portion of the component by positioning at least two holding claws 25 of a component gripping device 20 in predetermined positions, and applying a pressing force to the component on the board side using each holding claw.
