Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounters struggle to adjust the target position of heads with multiple pickup members, where the arrangement pitches are not displaceable, to enable simultaneous component pickup.
Innovation Solution
A suction position adjustment device that includes an imaging device to capture the component supply position, a display device to show the captured image with superimposed pointers, and a control device to adjust the target position of the head, allowing for simultaneous suction control of multiple pickup members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the arrangement pitch of pickup members is fixed and not displaceable, then the head structure is simplified, but the ability to adjust target position for simultaneous suction control is lost
Solution Approach 1:
The patent replaces the mechanical displacement mechanism (moving the pickup members relative to each other) with an optical field-based solution (imaging device capturing positions and control device calculating adjusted target positions). Instead of mechanically adjusting the physical arrangement of pickup members, the system uses image processing and computational methods to determine adjusted target positions that enable simultaneous suction control, thereby substituting a complex mechanical system with a more flexible control-based approach.
Solution Approach 2:
The patent uses an imaging device to create a visual copy (image) of the component supply positions and pickup member locations. This copied visual information is then processed by the control device to calculate adjusted target positions. By working with the copied image data rather than directly manipulating the physical pickup members, the system achieves position adjustment capability without requiring mechanical displacement mechanisms.
2Productivity
If multiple pickup members are used for simultaneous component pickup, then productivity is improved, but the complexity of position control and coordination increases
Solution Approach 1:
The patent implements a feedback mechanism where the imaging device continuously captures the actual positions of components on the tape and the pickup members. The control device uses this feedback information to calculate and determine adjusted target positions that account for any deviations or variations. This closed-loop feedback system enables coordinated control of multiple pickup members, ensuring they simultaneously reach their target positions despite the increased complexity of managing multiple actuators.
Solution Approach 2:
The control device serves multiple functions: it controls the imaging device to capture positions, processes the captured images to identify component and pickup member locations, calculates the adjusted target positions for simultaneous suction, and coordinates the movement of multiple pickup members. By consolidating these multiple functions into a single control device, the patent manages the complexity of controlling multiple pickup members while maintaining high productivity through simultaneous component pickup.

AI summary
A suction position adjustment device of a component mounter which includes a head having multiple pickup members and that executes simultaneous suction control for substantially simultaneously picking up multiple components with the multiple pickup members by moving the head to a target position that is determined to locate the multiple pickup members on the multiple components supplied from multiple feeders to a supply position. The suction position adjustment device includes an imaging device configured to image the supply position of the feeder from above, a display device, and a control device. The control device configured to control the imaging device so that an upper surface, at the supply position, in the multiple feeders of adjustment targets is captured and display, on the display device, captured multiple upper surface images and multiple pointers superimposed on the multiple upper surface images, when the target position is adjusted.
