Rotary Head Component Mounter Imaging Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting techniques using rotary heads with multiple component holders lack efficient imaging methods, leading to prolonged mounting times.
Innovation Solution
A component mounter with a rotary head that includes multiple component holders arranged along a circumferential orbit, an imaging unit with multiple positions, and a controller that executes an imaging sequence by rotating the holders to image each component holder at designated positions, allowing efficient imaging by positioning each holder at one of the imaging positions during rotation.

1Productivity
If a rotary head with multiple component holders is used to shorten mounting time, then productivity is improved, but imaging time increases because each holder must be imaged sequentially
Solution Approach 1:
The imaging function is segmented into multiple imaging units (first imaging unit and second imaging unit) positioned at different locations around the rotary head. Each imaging unit independently images component holders as they pass by, allowing parallel imaging operations that reduce total imaging time while maintaining high productivity
Solution Approach 2:
Multiple imaging units are pre-positioned at different angular positions around the rotary head to capture images of component holders at different stages of rotation. This preliminary positioning enables simultaneous imaging of multiple holders without waiting for sequential rotation to bring each to a single imaging point

AI summary
A component mounter comprises a mounting head that holds a plurality of nozzles. Two imaging positions are provided for the circumferential orbit along which the nozzles of the mounting head are arranged. While the nozzles are rotated continuously about the rotation axis, an operation of imaging the nozzles located at the imaging positions is performed for each of the imaging positions. Therefore, in a period when the nozzles rotate by an angle not larger than a predetermined angle around the rotation axis formed by the interval between the two imaging positions adjacent to each other along the circumferential orbit, imaging of the nozzles can be completed by locating each of the nozzles at one of the two imaging positions. As a result, it becomes possible to image the plurality of nozzles of the mounting head efficiently.
