Solution Overview
Problem
Existing vacuum insulation glass panel manufacturing methods face challenges such as inaccurate sealing of exhaust holes, potential foreign material retention, and complexity in handling varying panel sizes, leading to inefficiencies and potential damage during the manufacturing process.
Innovation Solution
A vacuum insulation glass panel manufacturing method and sealing cap closing apparatus that utilizes a clamping unit with a guide hole and holder to accurately position and press a sealing cap against the exhaust hole, preventing foreign material retention and simplifying the process for panels of different sizes by using a rack and pinion mechanism or similar elevating means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closing-off cap is held above the opening by a spring or similar member, then the cap can be positioned for sealing, but the cap may be displaced or dropped during movement, causing inaccurate sealing
Solution Approach 1:
The patent removes the spring or similar supporting member from the system. Instead of holding the closing-off cap above the opening during movement, the cap is directly placed on the opening without any supporting mechanism, eliminating the risk of displacement or drop while simplifying the device structure
Solution Approach 2:
The closing-off cap is pre-positioned directly on the opening before the glass panels are moved. This preliminary positioning ensures accurate sealing without requiring complex support mechanisms during the movement process
2Reliability
If a closing-off cap is held by a spring or similar member, then the cap can be positioned for sealing, but the member remains inside the glass panels after sealing, causing noise and breakage
Solution Approach 1:
The patent completely removes the spring or similar supporting member from the system. The closing-off cap is directly placed on the opening without any intermediate supporting structure, eliminating the source of noise and breakage that would occur if members remained inside the glass panels after sealing
3Manufacturing precision
If the plunger position is adjusted for each different panel size, then accurate sealing can be achieved, but the manufacturing process becomes considerably complicated
Solution Approach 1:
The patent removes the plunger mechanism entirely. Instead of using a plunger that requires position adjustment for different panel sizes, the closing-off cap is directly placed on the opening and sealed in place, eliminating the need for complex adjustment mechanisms while maintaining sealing accuracy
Solution Approach 2:
The simplified method allows the same apparatus to handle glass panels of different sizes without requiring adjustment mechanisms. The closing-off cap is universally applicable to various panel sizes through direct placement, making the manufacturing process simpler and more adaptable

Implementation Method 1
When the glass solder reaches a softening temperature, the closing-off cap is pressed by a plunger to seal the opening
Implementation Method 2
When the glass solder reaches a softening temperature
Implementation Method 3
An opening or an exhaust hole is formed in any one of the glass panels to form a vacuum space between the glass panels by pumping out or exhausting an air

AI summary
Disclosed are a method for manufacturing a vacuum insulation glass panel and a device for closing a sealing cap, the method and the device being for exhausting air between two glass panels and sealing the same. The device for closing the sealing cap, of the present invention, comprises a clamping unit, a holder, and an elevating device. The clamping unit has: an exhaust hole formed at one edge of the lower surface of a glass panel assembly; and a guide hole clamped to the edge of the adjacent glass panel assembly and formed to be aligned with the exhaust hole. The holder has the sealing cap, which is mounted in the guide hole so as to be movable along the guide hole, and on which glass soldering for closing the exhaust hole is applied. The elevating device moves the holder along the guide hole so as to press the sealing cap around the exhaust hole, such that the exhaust hole is closed by the sealing cap. The method for manufacturing a vacuum insulation glass panel, according to the present invention, heats the glass solder applied on the sealing cap before being put into a vacuum chamber, and then presses, by the operation of the elevating device, the sealing cap put into the vacuum chamber so as to join the sealing cap around the exhaust hole. According to the present invention, the holder having the sealing cap is mounted in the clamping unit, and then the clamping unit is clamped to the glass panel assembly, thereby enabling the exhaust hole to be accurately closed with the sealing cap.
