Spot-Welding Electrode Inspection with Separated Heat-Dissipating Control Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automotive production lines, spot-welding electrode inspection devices need to be compact due to limited space around industrial robots, but downsizing the casing can lead to heat accumulation, potentially damaging the control substrate during continuous use.
Innovation Solution
The camera unit and control unit are separate, with the control unit housed in a metal casing attached to a metal mount member, allowing for effective heat dissipation and enabling the camera unit to be installed near the industrial robot, while the control unit is connected to a personal computer, monitor, and industrial robot for efficient data processing and signal transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the casing housing the camera body and control substrate is downsized to fit limited space around the industrial robot, then the device can be installed in narrow spaces, but heat readily accumulates inside the casing which can adversely affect the control substrate during continuous use
Solution Approach 1:
The device is divided into two separate units: a camera unit for image capture and a control unit for processing. This segmentation allows the heat-generating control substrate to be isolated from the confined space requirements, enabling the camera unit to be placed in narrow spaces while the control unit can be positioned elsewhere with adequate ventilation.
Solution Approach 2:
The control substrate is extracted from the camera unit and placed in a separate control unit. This extraction removes the heat-generating component from the space-constrained area, allowing the camera unit to be downsized and installed in narrow spaces around the industrial robot without heat accumulation problems.
2Temperature
If the camera unit and control unit are separated and connected via camera cable, then the control unit can be positioned away from heat-sensitive areas, but the device complexity increases
Solution Approach 1:
A camera cable serves as an intermediary connection between the camera unit and control unit. This simple cable-based communication method enables separation of the heat-sensitive control substrate from the camera unit while maintaining functional connectivity, avoiding the need for complex wireless communication systems or additional processing interfaces.
