Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component placement systems with multiple placement heads risk interference when accessing a circuit board and pallet arranged in one direction, leading to potential collisions and inappropriate component placement.
Innovation Solution
A component placement apparatus with a controller that processes information to minimize overlapping movement areas among multiple placement heads by specifying component groups for simultaneous pickup and placement, ensuring efficient operation without interference.

Engineering Contradiction Analysis
1Productivity
If multiple placement heads simultaneously access the circuit board and pallet arranged in one direction, then productivity is improved through parallel operations, but interference and collision among placement heads occurs
Solution Approach 1:
The pallet is divided into multiple blocks in the direction extending in one direction with respect to the circuit board. Each placement head is assigned to access specific blocks, segmenting the working area to prevent interference while maintaining parallel operations. This segmentation allows multiple placement heads to operate simultaneously without collision by restricting each head to its designated block region.
2Productivity
If multiple placement heads operate simultaneously without area restriction, then productivity increases, but movement paths overlap causing interference
Solution Approach 1:
The working area is segmented into multiple blocks along the direction extending with respect to the circuit board. Each placement head operates within its assigned block, which simplifies path coordination by eliminating the need for complex real-time collision avoidance. This spatial segmentation reduces movement path complexity while enabling simultaneous operations.
Solution Approach 2:
The component supply units are pre-positioned on the pallet within specific blocks before the placement operation begins. The placement heads are pre-assigned to specific blocks based on the component locations and circuit board requirements. This preliminary arrangement of components and heads prevents movement path overlap during actual placement operations.

AI summary
The present invention is directed to a technique that avoids occurrence of interference among multiple placement heads, when multiple placement heads simultaneously access a circuit board, and a pallet which is arranged in one direction with respect to the circuit board. When the component placement part 150 having the multiple placement heads simultaneously pick up the components from the pallet 160 and simultaneously place the components on the circuit board, the controller 140 specifies a pair of component groups to be picked up simultaneously from the pallet 160 by the multiple placement heads and places the components on the circuit board, so that an area where the multiple placement heads move in overlapping manner is minimized, and the placement heads respectively pick up the components included in the pair of component groups being specified and place the components on the circuit board.
