Nozzle Head Holding Apparatus Using Negative Pressure Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic-component holding apparatuses are cumbersome and time-consuming to attach and detach nozzle heads, which reduces the efficiency of electronic-component mounting processes.
Innovation Solution
The apparatus employs a negative-pressure chamber system that allows the nozzle head to be easily attached and detached by controlling suction, using a head-related negative-pressure chamber supplied through a passage, enabling quick exchange of nozzle heads with or without manual or automatic assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a head clamping device with engaging pin and cam plate is used to hold the nozzle head, then the nozzle head can be securely held, but the attachment and detachment process becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces the manual mechanical clamping system (engaging pin and cam plate) with an automated suction-based holding system. The head holding member uses a negative pressure chamber that applies suction force to automatically hold the nozzle head, eliminating the need for manual operation of the clamping device and significantly reducing attachment and detachment time while maintaining secure holding.
Solution Approach 2:
The patent employs pneumatic principles by using a negative pressure chamber connected to a vacuum source. The negative pressure (suction) is applied to the head holding portion to securely hold the nozzle head. This pneumatic mechanism replaces the mechanical clamping system and enables automated, rapid attachment and detachment operations.
2Ease of operation
If manual operation of the head clamping device is required to attach and detach the nozzle head, then the operator can control the process, but the overall mounting efficiency is reduced
Solution Approach 1:
The patent implements self-service by enabling the head holding member to automatically grasp and release the nozzle head through controlled suction. The negative pressure chamber automatically holds the nozzle head when negative pressure is applied, and releases it when negative pressure is removed, eliminating the need for manual operation and significantly improving mounting efficiency.
Solution Approach 2:
The patent replaces the manual mechanical clamping system with an automated pneumatic system. The head holding member uses negative pressure to automatically attach and detach the nozzle head, transferring control from manual operation to automated pneumatic control, thereby improving productivity while maintaining ease of operation through simple pressure control.

Data Source
AI summary
An electronic-component holding apparatus and an electronic-component mounting system each of which assures that a nozzle head holding a plurality of suction nozzles is easily attached to, and detached from, a head holding member, are provided. A suction surface of a head holding member is held in close contact with a to-be-sucked surface of a revolver head so as to define a head-related negative-pressure chamber that holds the revolver head by utilizing suction. The revolver head is revolved, and moved upward and downward, with the head holding member.
