Problems solved by technology

[0004] The currently published vacuum glass patents are mainly to place the pre-prepared supports one by one on the glass sheet by manual or mechanical means, which has the following disadvantages: 1) The operation is cumbersome, the work intensity is high, and the number of vacuum glass supports There are about 1,600 pieces per square meter. Manual or mechanical layout, misplaced, missed, and over-placed supports occur from time to time, and the scrap rate is high; 2) The support itself has poor precision and varies in height, resulting in the Uneven force affects the quality and life of vacuum glass

Embodiment 1

[0027] see figure 1 , the preparation and placement method of the vacuum glass support is as follows: a piece of glass 1 (size 1800mm*1500mm) will be cleaned and dried on the 3D printer printing table; the glass glaze is ground and passed through 200 Mesh sieve, then pack into the 3D printer feeding chamber; Use CAD drawing software to draw the three-dimensional graphics of support 2 and the three-dimensional graphics of support 2 arrangement, wherein the shape of support 2 is a cylinder with a bottom diameter of 1mm and a height of 0.1mm. The supports are arranged in an m×n matrix, and the distance between rows and columns of the matrix is ​​30mm. Start the 3D printer, and the nozzle 3 at the outlet of the 3D printer is equipped with a heating device to heat the glass glaze, control the temperature of the printer’s output, and control the output volume through the pressure device to print the molten glass glaze on the glass layer by layer. On the chip, the thickness of each ...

Embodiment 2

[0029] see figure 2 , the preparation and placement method of the vacuum glass support are as follows: a piece of glass 1 (size 1200mm*700mm) for making vacuum glass is cleaned and dried and placed on the 3D printer printing table; the screened metal powder is loaded into 3D printer feeding chamber; CAD drawing software is used to draw the three-dimensional graphics of the support 2 and the three-dimensional graphics arranged in the vacuum glass. The shape of the support 2 is a circular ring with a bottom outer diameter of 1 mm, an inner diameter of 0.8 mm, and a height of 0.2 mm. The supports are arranged in an m×n matrix, and the distance between rows and columns of the matrix is ​​40mm. Start the 3D printer, the heating device installed on the nozzle 3 at the discharge port of the 3D printer will heat the metal powder, control the discharge temperature of the printer, control the discharge volume through the pressure device, and print the molten metal layer by layer on th...

Embodiment 3

[0031] On the basis of Example 1 or Example 2, after the preparation and placement of the support is completed, the vacuum glass can be obtained by completing corresponding operations such as assembling according to the existing vacuum glass preparation method.

[0032] Since the preparation of the supports adopts 3D printing technology, the precision of the supports is high, and the height difference of each support is small, which ensures that after the vacuum glass is combined, each support point is in contact with two pieces of glass, and the support points are evenly stressed, reducing glass fragmentation probability of cracking. In addition, 3D printing technology is used to complete the preparation and layout of the vacuum glass support in one step. The whole process is controlled by computer, the process is simple, the accuracy is high, and various errors in manual operation are avoided. At the same time, the production process is reduced and the production efficiency i...

Abstract

The invention discloses a preparation and distribution method of a vacuum glass and a supporter thereof. The preparation and distribution method of the supporter of vacuum glass comprises the following steps: drawing the three dimensional figure of the supporter and the three dimensional figure of a supporter assignment mode by using drawing software; arranging a glass flake on the printing tablet of a 3D printer, and filling the feeding chamber of the 3D printer with a bonding material; heating and fusing the bonding material, and printing the fused bonding material on glass in a preset position layer by layer according to the drawn three dimensional figure of the supporter under the control of the drawing software, and solidifying the bonding material to form the vacuum glass supporter; and completing printing and distribution of all the supporter on a glass panel under the control of the drawing software. The method improves the dimension and the distribution position precision of the vacuum glass supporter.

Description

technical field [0001] The invention relates to the technical field of vacuum glass, in particular to a method for preparing and laying vacuum glass and its support. Background technique [0002] Vacuum glass is a new type of glass deep-processing product, and it is the glass product with the best energy-saving effect in the world today. By blocking the conduction and convection heat transfer between glasses, vacuum glass has excellent heat preservation effect and effectively reduces the heat transfer coefficient of glass doors and windows. It is the current development direction of high-efficiency energy-saving glass. [0003] Since there is a vacuum chamber in the middle of the vacuum glass, in order to resist the external atmospheric pressure, it is necessary to arrange a small supporting point between the two pieces of glass to ensure the vacuum state between the two pieces of flat glass, so as to achieve the effect of heat insulation. The type and layout of the support...
