Component Mounter Temporary Placement Pressure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounters face inefficiencies in determining whether a component has been correctly placed on a temporary placement surface, leading to increased processing time and decreased throughput due to the need for image processing to verify component presence.
Innovation Solution
A component mounter equipped with a temporary placement surface featuring a hole for negative pressure supply, a pressure detecting device, and a control system that rapidly determines component placement by analyzing pressure states, allowing for immediate processing decisions based on the determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional component mounting device is used, then the device structure is simple, but it cannot accurately mount components on curved surfaces and causes damage to the components
Solution Approach 1:
The pressing member is designed to move between a pressing state (contacting the component) and a non-pressing state (retracted), allowing adaptive adjustment to curved surfaces. The movable support member enables the pressing member to follow the contour of curved components, achieving accurate mounting without damage while maintaining reasonable device complexity
Solution Approach 2:
The mounting device is divided into functional modules: a support member (fixed and movable), a pressing member, and a control unit. This segmentation allows the movable support member to independently adjust position, enabling precise adaptation to curved surfaces while keeping the overall device structure manageable
2Productivity
If manual inspection methods are used, then the inspection process is simple, but it requires significant time and labor
Solution Approach 1:
The inspection system replaces manual visual inspection with an automated image processing system using cameras and image processing units. This substitution dramatically improves inspection efficiency by automatically detecting component mounting status, position, and orientation while reducing time and labor requirements
Solution Approach 2:
The image processing system automatically inspects and identifies mounting errors without human intervention. The control unit autonomously processes image data, compares it against reference data, and determines inspection results, enabling the system to serve itself in the inspection process
3Reliability
If the pressing member continuously presses the component, then the component remains stable, but it may damage the component or prevent proper inspection
Solution Approach 1:
The pressing member operates periodically, switching between pressing state (during mounting) and non-pressing state (during inspection). This periodic action ensures component stability when needed while preventing damage and allowing proper inspection when the pressing member is retracted
Solution Approach 2:
The pressing member's force is dynamically adjusted through movement between pressing and non-pressing states. This dynamic control allows the system to provide stability during mounting operations while eliminating pressing force during inspection to prevent damage and ensure accurate measurement
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances throughput by rapidly verifying component placement on the temporary surface, reducing unnecessary processing and improving accuracy in component pickup and mounting operations.
Implementation Method 1
a pressure detecting device configured to detect pressure at the hole; and a control means configured to control the component pickup means and the moving means such that after the component supplied by the component supply means has been picked up by the component pickup means and before the component is mounted on the board, the component is temporarily placed at the specified position, wherein the control means, after performing control to temporarily place the component at the specified position, determines whether the component has actually been temporarily placed at the specified position based on the pressure state of the hole with negative pressure being supplied to the hole

AI summary
Control device 80 of component mounter 11 performs control such that after a component supplied by reel unit 56 is picked up by nozzle 40 of mounting head 24 and before the component is mounted on board 12, the component is temporarily placed at a specified position of temporary placement surface 71. Also, control device 80, after performing control such that the component is temporarily placed at the specified position, determines whether the component has actually been temporarily placed at the specified position based on the pressure state at a hole provided at the specified position of temporary placement surface 71 to which negative pressure is being supplied, and performs processing according to the determination result. Because the determination of whether the component has actually been temporarily placed is based on the pressure state of the hole provided in temporary placement surface 71, the determination is performed rapidly compared to a case in which the presence of the component is checked by analyzing an image of temporary placement surface 71 captured from above.
