Replaceable Die Supply Head for Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency in delivering dies from a die supply apparatus to a component mounting machine due to mismatched numbers of nozzles between the supply head and the mounting head, leading to degraded production tact time.
Innovation Solution
The die supply apparatus is configured to be adaptable, allowing either direct or shuttle delivery methods, with an upside-down inverting mechanism and a shuttle mechanism to align the die arrangement with the mounting head's nozzle arrangement, enabling simultaneous suction and delivery of multiple dies, and allowing for manual or automatic replacement of the supply head to match the number and arrangement of nozzles with the mounting head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the supply head of the die supply apparatus is not configured to be replaceable, then the structure is simple and easy to manufacture, but the number of nozzles cannot be matched to different mounting heads, causing inefficient die delivery and degraded production tact time
Solution Approach 1:
The supply head is designed with replaceable nozzle units that can be dynamically configured to match different mounting head requirements. This allows the system to adapt its nozzle count and arrangement based on the specific mounting task, resolving the contradiction between maintaining simple structure and achieving high productivity through nozzle matching.
Solution Approach 2:
The supply head is designed as a universal interface that can accommodate multiple nozzle configurations. By making the nozzle units replaceable, a single supply head structure can serve multiple mounting head types with different nozzle requirements, thereby improving die delivery efficiency without requiring multiple specialized supply heads.
2Productivity
If the number of nozzles of the supply head does not coincide with the number of nozzles of the mounting head, then the supply head structure remains fixed and simple, but the dies cannot be efficiently delivered, degrading production tact time
Solution Approach 1:
The nozzle units on the supply head are designed to be replaceable, allowing dynamic reconfiguration of the nozzle count and arrangement to match different mounting head specifications. This dynamic adaptability enables efficient die delivery across various mounting scenarios while maintaining a relatively simple base structure.
Solution Approach 2:
The supply head is segmented into modular nozzle units that can be independently replaced. This segmentation allows the system to adjust the number and configuration of nozzles to precisely match the mounting head requirements, thereby improving production tact time without complicating the overall supply head structure.
3Productivity
If multiple dies are to be simultaneously suctioned and delivered, then the nozzle arrangements must be aligned, but this requires replaceable supply heads to match different mounting head configurations
Solution Approach 1:
The replaceable nozzle units enable dynamic matching of supply head configuration to mounting head requirements, allowing multiple dies to be simultaneously suctioned and delivered when needed. This dynamic configurability achieves high simultaneous delivery capability without requiring a complex fixed multi-nozzle structure for every possible configuration.
Solution Approach 2:
The supply head with replaceable nozzle units serves as a universal platform that can achieve multiple die simultaneous delivery by configuring the appropriate number and arrangement of nozzle units. This universal design allows the system to achieve high productivity through simultaneous delivery without requiring separate specialized mechanisms for each configuration.

AI summary
A supply head 33 of a die supply apparatus 12 is detachably held by a head holding unit 40 of a head moving mechanism 34. The supply head 33 held by the head holding unit 40 is configured to be replaceable with a supply head which has the same number of nozzles as the number of nozzles of a mounting head 15 of a component mounting machine 11, and a nozzle arrangement of the supply head 33 of the die supply apparatus 12 is caused to be the same arrangement as a nozzle arrangement of the mounting head 15 of the component mounting machine 11. Before starting production, a worker checks whether the number of nozzles of the supply head 33 of the die supply apparatus 12 coincides with the number of nozzles of the mounting head 15 of the component mounting machine 11. If both the numbers of nozzles do not coincide with each other, the supply head 33 of the die supply apparatus 12 is replaced with a supply head which has the same number of nozzles as the number of nozzles of the mounting head 15 of the component mounting machine 11, and then, production starts.
