Pickup Head Nozzle Switching for Face-Down Component Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component supply devices face challenges in performing face-down supply efficiently, as they require time-consuming component flipping by the pickup head, leading to longer component delivery times to the mounter.
Innovation Solution
The component supply device incorporates multiple suction nozzles on the pickup head that can switch between pickup and transfer positions, aligning with the mounter's suction nozzles to enable simultaneous pickup and transfer of multiple components, thereby reducing the time required for face-down supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If face-down supply is performed using conventional pickup head with single nozzle, then component can be supplied to mounter, but it takes longer time due to sequential pickup and flip operations
Solution Approach 1:
The pickup head is divided into multiple independent suction nozzles (first, second, third nozzles) that can operate simultaneously. Each nozzle can pick up and flip components independently, allowing parallel processing of multiple components to reduce overall operation time.
Solution Approach 2:
The pickup and flip operations are merged into a single integrated pickup head structure. The suction nozzles are positioned to perform both pickup and flipping functions without requiring separate operational steps, combining multiple functions into one device.
2Productivity
If multiple suction nozzles are used on pickup head, then multiple components can be picked up simultaneously, but device complexity increases
Solution Approach 1:
The pickup head with multiple suction nozzles serves multiple functions: picking up components, flipping them, and transferring them to the mounter. This multi-functional design consolidates what would otherwise require separate devices into a single unit, managing complexity through functional integration.
Solution Approach 2:
The suction nozzles are designed to be movable or adjustable in position, allowing them to adapt to different component types and mounting requirements. This dynamic capability enables the same pickup head structure to handle various component configurations without requiring multiple specialized devices.

AI summary
The component supply device includes a table on which a wafer sheet is carried and a pickup head which picks up a component on the wafer sheet carried on the table. The pickup head includes multiple component supply side suction nozzles, and a switching mechanism which switches the multiple component supply side suction nozzles between a pickup position at which the tip of the multiple component supply side suction nozzles faces down and a transfer position at which the tip of the multiple component supply side suction nozzles faces up. The arrangement of the multiple component supply side suction nozzles corresponds to the arrangement of multiple mounter side suction nozzles equipped on the mounting head of the mounter.
