Plate Ejection Device with Vertical Inversion and Vacuum Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ejection devices for plate production systems are inefficient in removing panels with spacers, as conventional squeezing processes are not suitable for concealing spacers in a lower, lateral position, making the ejection process complex and time-consuming.
Innovation Solution
The ejection device employs a movement from bottom to top, with an ejection unit that can move vertically or slightly obliquely, using a vacuum holding device or gripping arms to push panels out of the mold frame, and a holding device that can move vertically or horizontally to position the panels, allowing for efficient ejection and placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional squeezing processes are used to eject panels, then the ejection can be performed, but the process becomes complex and time-consuming when panels have spacers that need to be concealed in a lower, lateral position
Solution Approach 1:
The patent inverts the conventional ejection approach by using a bottom-to-top ejection direction instead of the traditional top-to-bottom squeezing process. The ejection unit is positioned at the bottom of the mold frame and pushes the panel upward, which simplifies the handling of panels with spacers and enables more efficient ejection.
Solution Approach 2:
The patent replaces the mechanical squeezing process with a vacuum holding and ejection system. The vacuum holding unit creates a vacuum field to grip the panel from below, and the ejection unit pushes the panel upward using controlled mechanical movement, eliminating the need for complex squeezing mechanisms.
2Productivity
If a bottom-to-top ejection movement is used, then the ejection process is simplified and quickened, but the holding and positioning of ejected panels requires additional vertical or horizontal movement capability
Solution Approach 1:
The holding device is designed with multi-functionality, capable of both vertical and horizontal movement to handle panels at different stages of the ejection process. This universal design allows the same device to perform multiple functions: holding the panel during ejection, positioning it vertically, and transporting it horizontally to the desired location.
Solution Approach 2:
The vacuum holding unit acts as an intermediary between the ejection unit and the panel. It temporarily grips the panel using vacuum pressure, enabling controlled transfer and positioning without direct mechanical contact from the ejection unit, thus simplifying the overall handling process.

Function Achieved in This Case
This approach simplifies and quickens the ejection process by enabling the panels to be pushed out vertically, using vacuum or gripping mechanisms, allowing for precise control and efficient handling of panels with spacers, improving the overall efficiency of the plate production process.
