Component Mounter Push Mechanism for Adjustable Pitch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component mounters face limitations in securely mounting components with protruding connection leads or large dimensions due to fixed mounting tool pitch, restricting adaptability and increasing complexity for varying component sizes.
Innovation Solution
A component mounter with two mounting units, each equipped with a tool rotation device and a component handling tool featuring a protruding portion offset from the base section, allowing adjustable distance between push locations without increasing the mounter's complexity, enabling secure mounting of components with varying pitch distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between component mounting tools is fixed, then the mounting unit structure is simple, but the types of components that can be manipulated are limited
Solution Approach 1:
The component handling tool incorporates a protruding portion that extends downward from the base section, with its second end positioned offset from the tool attaching position. This dynamic geometric configuration allows the effective push distance between tools to be varied without changing the physical distance between tool attachment points, enabling adaptation to different component pitches while maintaining a simple fixed mounting unit structure.
2Adaptability or versatility
If the attachment position of mounting units is adjusted to vary push locations, then different component pitches can be accommodated, but the complexity of the mounting unit increases
Solution Approach 1:
The invention extracts the pitch adjustment function from the mounting unit structure itself and relocates it to the component handling tool geometry. By incorporating the offset protruding portion in the tool rather than adjusting the mounting unit attachment positions, the pitch variation capability is achieved without increasing mounting unit complexity.
3Adaptability or versatility
If the attachment position of component handling tools is adjusted to vary push locations, then different component pitches can be accommodated, but the setup time increases
Solution Approach 1:
The component handling tool is pre-configured with a protruding portion having a specific offset distance from the tool attaching position. This preliminary geometric configuration allows the tool to automatically achieve the correct push location spacing for different component pitches without requiring time-consuming adjustments during setup.

AI summary
A component mounter including a conveyance device configured to convey a board and hold the board at a specified position; a supply device configured to supply a component; and two mounting units each including a tool rotation device and a component handling tool. The component handling tool includes a base section and a protruding portion extending in a downward direction from the base section, a first end of the protruding portion attached to the base section at a tool attaching position, and a second end of the protruding portion positioned offset with respect to the tool attaching position in a direction perpendicular to the downward direction. The component mounter uses the component handing tools to simultaneously push a component at two push locations so as to insert the component onto the board.
