Suction Nozzle Identification via Sideview Camera
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component mounting devices cannot recognize identification marks on suction nozzles when they are assembled to the shaft main body, limiting the ability to identify and manage the nozzles during operation.
Innovation Solution
The component mounting device incorporates a sideview camera that can image an identification mark on the side surface of the suction nozzle, even when it is assembled, by adjusting the vertical position of the nozzle shaft and using a rotary-type mounting head with a rotator and support member, allowing simultaneous imaging of both the electronic component and the identification mark.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the identification mark is printed on the upper surface of the flange part, then the mark can be clearly printed, but the mark cannot be recognized unless the suction nozzle is removed from the shaft main body
Solution Approach 1:
The identification mark is relocated from the upper surface (vertical dimension) to the side surface (horizontal dimension) of the flange part. This dimensional change allows the sideview camera to capture the mark through lateral imaging while the nozzle remains assembled to the shaft main body, resolving the contradiction between mark recognition and operational status.
2Measurement precision
If a separate camera system is added for nozzle identification, then the identification capability is improved, but the device complexity increases
Solution Approach 1:
The sideview camera is integrated into the mounting head to perform multiple functions: capturing images of electronic components held by the suction nozzle and reading identification marks on the nozzle itself. This multi-functional approach eliminates the need for separate dedicated identification cameras, reducing overall system complexity while maintaining enhanced identification capability.
3Measurement precision
If the suction nozzle is removed for identification, then the mark can be recognized, but the operational time is lost
Solution Approach 1:
The identification mark is positioned on the side surface of the flange part, which is accessible for imaging before the nozzle is inserted into the shaft main body. The sideview camera captures the mark during the approach phase or at the initial position, allowing identification to occur preliminarily without interrupting the subsequent mounting operation, thus maintaining productivity.

AI summary
A component mounting device mounts an electronic component on a printed circuit board, and includes a sideview camera which takes an image of a side surface of a target, a mounting head having a nozzle shaft, and a driving device which moves the mounting head to a planar direction on a base. The nozzle shaft includes a shaft main body movably supported to a vertical direction with respect to the mounting head, and a suction nozzle attached at a tip of the shaft main body to suction and hold the electronic component, and an identification mark which identifies the suction nozzle is provided on a side surface of the suction nozzle.
