Component Mounting Device Z-Axis Slider Flexible Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component mounting devices face inefficiencies in throughput and space utilization due to long Z-axis nozzle strokes and the need for extensive wiring arrangements when trying to compact the device by attaching an X-axis slider to a Z-axis slider.
Innovation Solution
A component mounting device with a head loaded on a Z-axis slider attached to an XY robot, allowing the nozzle to move in a shorter Z-axis direction and bundling wiring tubes in a flexible section that expands and contracts with the movement of the Z-axis and XY sliders, reducing space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the Z-axis direction stroke of the nozzle is made long to ensure proper pickup and mounting operation, then the operational range is sufficient, but throughput deteriorates
Solution Approach 1:
The patent introduces a Z-axis slider that moves the head in the Z-axis direction, separating the pickup/mounting operation from the XY positioning. This allows the nozzle to maintain a short Z-axis stroke while the head itself moves to the lower pickup position, effectively resolving the contradiction by operating in an additional dimensional space.
2Productivity
If the X-axis slider is attached to a Z-axis slider to shorten the nozzle stroke, then throughput is improved, but the construction becomes non-compact due to new Z-axis wiring requirements
Solution Approach 1:
The patent uses a flexible wiring tube that can expand and contract as the Z-axis slider moves. This flexible tube eliminates the need for rigid wiring connections, allowing the Z-axis slider to be integrated without requiring complex rigid wiring arrangements, thus maintaining compact construction while enabling the throughput improvement.
3Area of stationary object
If multiple wiring tubes are arranged separately to ensure proper connection to each slider, then connection reliability is maintained, but the space required for wiring increases
Solution Approach 1:
The patent merges multiple wiring tubes (first wiring tube for XY slider and second wiring tube for Z-axis slider) into a single flexible wiring assembly. This bundled arrangement reduces the total space required for wiring while maintaining reliable connections to both sliders through the flexible tube's ability to accommodate movements of both sliders simultaneously.

AI summary
Provided is a component mounting device including: an XY robot, a Z-axis slider attached to an X-axis slider of the XY robot so as to be movable in the Z-axis direction, a head loaded on the Z-axis slider, and a nozzle attached to head 30 so as to be movable in the Z-axis direction. With the component mounting device, a component supplied from a component supply unit is picked up by the nozzle, transported to a specified position on a board, and mounted. A flexible section with an external appearance with a U shape that is expandable and contractible in the X-axis direction and the Z-axis direction is arranged to the rear of a Y-axis slider. A portion of an X-axis wiring tube and a portion of a Z-axis wiring tube are bundled together in the flexible section.
