Diamond canvas gluing method

A diamond painting and gluing technology, applied in the directions of copying/marking methods, coatings, devices for applying liquid to the surface, etc., can solve the problem of inability to achieve no excess glue around the affixed drill, inability to fully control the size, and increase the amount of squeegee. Problems such as the difficulty of matching the version, to achieve the effect of eliminating the silk screen random glue process, improving efficiency and quality, and improving aesthetics

Problems solved by technology

[0004] 1. Difficulty in plate alignment: The thermal expansion and contraction of the finished screen frame is very small and can be ignored, while the thermal expansion and contraction of the diamond canvas is obvious. Different batches of diamond canvases with different thicknesses are printed with patterns and glued Sometimes, there will be errors with the corresponding screen frame, which greatly increases the difficulty of squeegee alignment. Misalignment of squeegee often occurs (manual work is difficult to control the quality of mass production). Currently, the diamond canvas digital printing on the market, The best effect is to use disperse water-based sublimation ink to print the diamond canvas, the color is bright and lifelike, the diamond canvas is delicate and smooth, and it is incomparable to the diamond canvas printed on oil canvas (oil-based weak solvent ink)
Dye-sublimation fabric digital printing needs to use transfer printing machine to develop color at high temperature (at a temperature of about 240 degrees for about 30 seconds), and the shrinkage ratio of the fabric can reach more than 2%. The pressure of the printing machine, the temperature of the transfer printing machine, the speed of the transfer printing, and the impact of the transfer printing machine’s feed force. At present, it is impossible to completely control the size of the shrunk, which brings many difficulties to the later screen squeegee.
[0005] 2. It is impossible to realize that there is no excess glue around the place where the diamond is pasted: the screen file made by the existing process will be larger than the surrounding area of ​​the digitally printed diamond canvas
In this way, it is convenient to scrape the glue on the plate, and for the convenience of the plate, the gluing file is composed of squares, and when the flat-bottomed round drill is pasted, the background of the corresponding color block under the drill is square, and the glue is also square. After the round diamond is pasted, there will be an excess area of ​​glue exposed outside. Similarly, after the square diamond is pasted, the pattern background and the outer edge of the square diamond will also have excess area of ​​glue exposed. The existing process of gluing is very unsightly.

Embodiment 1

[0025] Such as Figure 1-4 As shown, the gluing operation is carried out on the diamond canvas through a numerical control gluing machine. The gluing machine includes a fixed platform 1 for fixing the diamond canvas, a scanning imaging system 2 for scanning, a removable nozzle 3, and a driving nozzle 3 to move the coating. Glue and scanning imaging system 2 moves the driving mechanism for scanning, and the driving mechanism adopts the existing three-axis numerical control system, which will not be repeated here.

[0026] Specifically include the following steps:

[0027] Step 1: Determine the gluing pattern and make gluing positioning points; in step 1, set the positioning points according to the corresponding diamond sticking position of the diamond painting pattern. The gluing positioning point file, the gluing positioning point file includes several central positioning points, and each central positioning point corresponds to the positioning point on the diamond painting p...

Embodiment 2

[0033] by figure 2 Take Apple as an example. Apple is the pattern to be pasted with diamonds, that is, the glued pattern. Other patterns are patterns without diamonds. Set the positioning points according to the corresponding diamonds of the diamond painting pattern. Each positioning point is the pattern that will be pasted with diamonds later. The central positioning point of , thus generating the gluing positioning point file;

[0034] Put the diamond canvas on the digital printing machine for printing, the diamond painting pattern and the gluing positioning points are printed on the canvas together, and a set of nozzles of the digital printing machine reads image 3 In the figure, the data of CMYK color channel 4 is printed with dye-sublimation ink. Another set of nozzles read image 3 Spot color channel data is gluing channel 5, printing and scanning to read ink. Note: Some digital printing machines on the market can combine two pictures and print together, that is, se...

Abstract

The invention relates to the technical field of diamond canvas gluing, in particular to a diamond canvas gluing method. The diamond canvas gluing method comprises the following steps that 1, gluing positioning points are manufactured; 2, digital printing is carried out so that a diamond picture pattern and the gluing positioning points are jointly printed on a diamond canvas in a jet printing mode; 3, the diamond canvas is fixed and scanned, and gluing positioning point information on the diamond canvas is obtained; and 4, inputting into a gluing machine is performed, and gluing is performed on the diamond canvas according to the scanned and read positioning point information. According to the diamond canvas gluing method, gluing convenience is improved, and gluing is attractive.

Description

technical field [0001] The invention relates to the technical field of diamond canvas gluing, in particular to a diamond canvas gluing method. Background technique [0002] DIY diamond painting designers organically combine delicate and sparkling man-made crystal flat-bottomed round or square diamonds with exquisitely designed background patterns, and the digitally printed diamond canvas needs to be glued to the place where the diamond is to be pasted, and there is no need to paste the diamond The background pattern cannot be glued. The existing process of gluing is screen printing and squeegeeing. The process of screen printing: printing film or sulfuric acid paper (make the place where the drill is pasted into a black color block), making a frame (made of aluminum alloy or iron), Mount the screen cloth in the frame and fix it, apply photosensitive glue evenly, place the printed film on it for exposure, rinse the screen frame with water, and save the squeegee screen frame ...
