Solution Overview
Problem
In component mounting machines with multiple transfer devices, individual management of thermal correction processes leads to inefficiencies due to unnecessary standbys and irregular thermal correction frequencies, resulting in reduced production efficiency.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If thermal correction processing is performed individually for each component transfer device, then thermal deformation influence is reduced, but production efficiency is reduced due to unnecessary standbys
Solution Approach 1:
The patent merges the thermal correction processing of multiple component transfer devices by having them perform thermal correction simultaneously or in an integrated manner. The control device coordinates the thermal correction timing across devices so that they undergo thermal correction together rather than individually, eliminating the standby time that occurs when one device waits for another. This combining approach maintains manufacturing precision while improving production efficiency.
2Manufacturing precision
If thermal correction processing is performed at regular intervals, then thermal deformation is corrected, but unnecessary thermal correction is performed reducing production efficiency
Solution Approach 1:
The patent implements dynamic thermal correction timing based on actual operating conditions rather than fixed regular intervals. The control device monitors the operational state of component transfer devices and determines thermal correction timing dynamically, performing thermal correction only when necessary based on accumulated operation time, temperature changes, or other operational parameters. This dynamic approach avoids unnecessary thermal correction processing while maintaining mounting precision.
3Productivity
If component transfer devices operate at high speed, then production efficiency is improved, but thermal deformation increases affecting mounting precision
Solution Approach 1:
The patent implements periodic thermal correction action during high-speed operation. Instead of continuous thermal correction which would slow down production, the system performs thermal correction at periodic intervals based on operational conditions. The control device monitors operation duration and temperature rise, triggering thermal correction periodically when thermal deformation reaches a threshold level, thereby maintaining precision without continuously interrupting high-speed production.

AI summary
A component mounting machine provided with multiple component transfer devices each have a mounting nozzle, a movable section and an XY driving mechanism and perform a component mounting operation, and a control device that controls component mounting operation and performs thermal correction processing that reduces influence of thermal deformation accompanying temperature change of at least one of the movable section and the XY driving mechanism, in which the control device has an implementation period determination section that individually determines an implementation period of the thermal correction processing for each of the component transfer devices based on operation circumstances of each component transfer device, and a thermal correction implementation section that simultaneously performs thermal correction processing for the multiple component transfer devices when it is determined that the implementation period of the thermal correction processing is reached for either of the component transfer devices by the implementation period determination section.
