Printed Board Working Apparatus Head Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printed board working apparatuses face a reduction in the region where all working heads can perform work as the number of working heads increases, leading to a localized area where no working heads can operate.
Innovation Solution
The solution involves a printed board working apparatus with a movable head support system that allows the base member to change its position based on a predetermined rule, ensuring the moving center of the working heads aligns with the movable region center, even when adding or removing working heads, thereby maintaining a wider operational region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of working heads is increased, then the number of coating solutions that can be applied increases, but the region where all working heads can perform work becomes narrower
Solution Approach 1:
The base member is made movable relative to the moving member, allowing its position to be adjusted dynamically. This enables the system to adapt the configuration of working heads to maintain an optimal common working region regardless of the number of heads installed
Solution Approach 2:
The base member serves multiple functions: it supports the working heads, provides a movable platform that can be repositioned, and acts as an interface between the moving member and the printed board. This multi-functionality allows the same component to address both the need for multiple working heads and the need to maintain a common working region
2Adaptability or versatility
If a working head is added to increase the number of coating solutions, then the versatility of the apparatus increases, but a region appears where none of the working heads can perform work
Solution Approach 1:
The movable base member allows the system to dynamically reconfigure the positions of working heads. When a new working head is added, the base member can be repositioned to optimize the distribution of all working heads across the printed board, ensuring maximum operational coverage without leaving uncovered regions

AI summary
A printed board working apparatus includes a transport device which transports a printed board in a horizontal direction, and a moving member which moves in a horizontal direction above the transport device. Either of the transport direction of the transport device and a horizontal direction perpendicular to the transport direction is defined as an installation direction. The printed board working apparatus includes a plurality of component attaching portions which are aligned in the installation direction and move together with the moving member. The printed board working apparatus also includes at least one working head which performs work on the printed board held by the transport device. Either of a form in which the plurality of component attaching portions are arranged on the moving member and a form in which the plurality of component attaching portions are arranged on a base member moving together with the moving member is adopted. The working head is attached to at least one component attaching portion out of the plurality of component attaching portions, and can change a position relative to the moving member in the installation direction. A region where the working head cannot perform work as the number of working heads increases is reduced.
