Engineering Contradiction Analysis
1Quantity of substance
If boards of different kinds are produced by a plurality of production lines with component mounting apparatuses controlling boards of different kinds to be grouped and produced as one board unit, then the occurrence of intermediate stock of boards of a particular kind is suppressed, but the efficiency in board production is not enhanced
Solution Approach 1:
The apparatus divides the board transfer and component mounting operations into separate functional units (first board transfer device, second board transfer device, first component placing head, second component placing head) that can operate independently and simultaneously. This segmentation allows one board to be transferred while components are mounted on another board, eliminating intermediate stock while maintaining high production efficiency through parallel processing.
Solution Approach 2:
The system performs preliminary actions by preparing component mounting operations in advance while boards are being transferred. The controller coordinates component placing heads to mount components on boards that are already in position or即将 to be in position, so that when boards are transferred, component mounting has already been prepared or is in progress, eliminating waiting time and intermediate stock.
2Ease of operation
If component mounting apparatus mounts components on boards sequentially, then the operation is simple, but the production efficiency is low
Solution Approach 1:
The apparatus merges board transfer operations with component mounting operations into a coordinated simultaneous process. The first board transfer device and second board transfer device operate in parallel with the first component placing head and second component placing head, combining what would traditionally be sequential operations into unified parallel processing that maintains operational simplicity through automated coordination while dramatically improving production efficiency.
Solution Approach 2:
The system ensures continuity of useful action by maintaining simultaneous board transfer and component mounting operations without interruption. The controller continuously coordinates the board transfer devices and component placing heads so that boards are constantly being transferred and mounted without idle waiting time, eliminating the stop-start nature of sequential operations and maximizing production efficiency.
3Productivity
If two parallel-arranged board transfer devices and component placing heads operate in alternate fashion, then component mounting efficiency is enhanced, but the complexity of controlling multiple devices increases
Solution Approach 1:
The controller implements feedback mechanisms to monitor the status of board transfer devices and component placing heads, automatically adjusting operations based on real-time conditions. This feedback system coordinates the parallel operations of multiple devices, managing the complexity through automated status monitoring and dynamic operation adjustment rather than manual coordination.
Solution Approach 2:
The controller serves as a universal coordination unit that manages multiple board transfer devices and component placing heads with different functions. By designing the control system to handle various operations (board transfer, component mounting, coordination between parallel devices) through a single multi-functional controller, the apparatus reduces overall system complexity while maintaining high component mounting efficiency.

AI summary
In a component mounting apparatus, when one of first and second board transfer devices is performing the unloading and loading of boards, a controller operates a component placing device to mount components on a first or second board loaded by the other board transfer device. Thus, it is possible to effectively utilize the time which is taken for the unloading and the loading of either boards, for component mountings on the other board, so that the efficiency in producing boards can be enhanced. Further, since the controller executes a control so that while component mountings are performed on the first boards of M-sheets on the first board transfer device, component mountings are performed on the second boards of N-sheets on the second board transfer device, it is realized to suppress the occurrence of an intermediate stock of either boards where the first boards of the M-sheets and the second boards of the N-sheets are required.
