Component Mounter Head Adjusts Digital Potentiometer Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When mounting multiple components on a board, incompatibility of their characteristic values can lead to poor functionality, as seen when a component's electrostatic capacity value is not suitable for another's resistance value, resulting in one or both components not functioning correctly.
Innovation Solution
A component mounter equipped with a characteristic value measuring device and a head that adjusts the resistance value of a digital potentiometer based on the measured characteristic value of another component, ensuring compatibility and efficient mounting by using a control section to identify and adjust the resistance value of the second component to match the first component's requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple components are mounted on a board without adjusting their characteristic values, then mounting efficiency is maintained, but component compatibility and functionality deteriorate
Solution Approach 1:
The characteristic value measuring device measures the characteristic value of the first component before mounting, and the control section determines the appropriate characteristic value for the second component in advance. This preliminary measurement and determination process ensures component compatibility is established before the mounting process completes, resolving the contradiction between maintaining mounting efficiency and ensuring component compatibility.
Solution Approach 2:
The system measures the actual characteristic value of the first component, feeds this information back to the control section, which then determines the corresponding characteristic value for the second component. This feedback mechanism ensures that component compatibility is dynamically adjusted based on actual measured values, resolving the contradiction between mounting efficiency and component compatibility.
2Reliability
If the characteristic value of a component is adjusted to match another component, then component compatibility improves, but the complexity of the mounting device increases
Solution Approach 1:
The head is designed to perform multiple functions: it can measure the characteristic value of components, determine appropriate characteristic values for other components, and mount components with adjusted characteristic values. By integrating these functions into a single multi-functional head, the system achieves component compatibility without proportionally increasing overall device complexity.
Solution Approach 2:
The characteristic value measuring device, the determination logic, and the mounting function are merged into an integrated system where the control section coordinates all operations. This consolidation reduces the need for separate independent systems, achieving component compatibility while managing device complexity through functional integration.
3Reliability
If the resistance value of the second component is adjusted based on the first component's characteristic value, then component functionality improves, but processing time increases
Solution Approach 1:
The system replaces manual measurement and adjustment processes with automated electronic measurement and control. The characteristic value measuring device automatically measures the first component, and the control section automatically determines and applies the appropriate characteristic value to the second component. This automation substitutes mechanical/manual operations with electronic systems, improving component functionality while minimizing additional processing time.

AI summary
Component mounter 1 mounts at least two components, first component 11 and second component 12, onto the same board 10. Component mounter 1 is provided with characteristic value measuring device 20 that measures a characteristic value of first component 11, and head 40 that mounts each of first component 11 and second component 12 on board 10. Second component 12 is a digital potentiometer provided with receiver section 123 that receives information from head 40, variable resistance section 124 for which the resistance is variable, and control section 121 that controls the resistance value of variable resistance section 124. Head 40 is provided with receiver section 403 that receives information from characteristic value measuring device 20, sender section 404 that sends information to second component 12, power source 405 that supplies electric current to variable resistance section 124, memory section 402 that memorizes the resistance value of second component 12 according to the characteristic value of first component 11, and control section 401. Control section 401 of head 40 receives a characteristic value of first component 11 measured by characteristic value measuring device 20 from characteristic value measuring device 20 via the receiver section 403, identifies the resistance value of the second component 12 from memory section 402 based on the received characteristic of first component 11, and sends the identified resistance value of the second component 12 to the second component 12 via sender section 404. Power source 405 of head 40 supplies electric current to variable resistance section 124 of second component 12. Control section 401 of head 40, with respect to control section 121 of second component 12, receives the resistance value of the second component 12 received from head 40 via receiver section 123 of the second component 12, and with electric current flowing in variable resistance section 124, adjusts the resistance value of variable resistance section 124 based on the received resistance value of the second component 12.
