Filter Removal Method for Component Suction Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component suction heads require complex and time-consuming operations for filter removal, mounting, and exchange, making automatic filter exchange virtually impossible due to the need for multiple steps and manual intervention.
Innovation Solution
A method and device for easily removing and mounting filters by compressing and deforming them within a filter holding space, allowing for simple press-fitting and automatic exchange, utilizing a filter removal unit, supply unit, and mounting unit to automate the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter is mounted using threadable engagement with holder and ring member, then the filter can be securely fixed in the nozzle block, but the mounting and removal operations become complex and time-consuming
Solution Approach 1:
The filter mounting structure is segmented into three functional parts: filter holder (with externally threaded portion), filter (with internally threaded portion), and ring member (with engagement protrusion). This segmentation allows each component to perform its specific function independently, simplifying the overall mounting and removal process while maintaining secure fixation.
Solution Approach 2:
The ring member is extracted as a separate functional element that provides the engagement mechanism. The ring member's engagement protrusion interacts with the groove in the filter holder, creating a simple locking mechanism that enables easy mounting and removal without complex threading operations.
2Reliability
If multiple mounting operations are required for filter installation, then the filter can be securely mounted, but the filter exchange process becomes too time-consuming for automation
Solution Approach 1:
The filter holder is pre-equipped with an externally threaded portion that engages with the internally threaded portion of the filter. This preliminary threading arrangement allows the filter to be quickly mounted and removed as a single unit without requiring multiple separate operations, making the process suitable for automation.
Solution Approach 2:
The ring member with engagement protrusion automatically locks onto the groove in the filter holder during mounting, creating a self-locking mechanism. This self-service feature ensures secure mounting while allowing for quick removal by simply disengaging the ring member, enabling automated filter exchange.
3Reliability
If the filter is firmly fixed in the nozzle block, then the filter can effectively remove foreign matters, but the filter removal and exchange operations become difficult and time-consuming
Solution Approach 1:
The filter mounting system transitions from a static fixed connection to a dynamic engagement system. The ring member can be easily engaged or disengaged from the groove, allowing the filter to be firmly fixed during operation but quickly removed when needed, reducing exchange time while maintaining filtration effectiveness.
Solution Approach 2:
The engagement mechanism is localized to specific features: the groove in the filter holder and the engagement protrusion on the ring member. This localized engagement design provides strong fixation where needed while allowing for quick release, balancing filtration security with exchange efficiency.

AI summary
A filter removal method for removing a filter held in a filter holding space provided in a tip part of a nozzle shaft in a component suction head, in which a suction nozzle is detachably attached to the tip part of the nozzle shaft, from the component suction head. The method comprises a deforming step of compressing and deforming the filter in the filter holding space, and a discharging step of discharging the compressed and deformed filter from the filter holding space.
