Description

Technical Field

[0001] The present invention belongs to the technical field of ceramic atomizing cores of atomizers, and particularly relates to a blind printing method for ceramic products. Background Art

[0002] When an atomizer adopts a ceramic atomizing core structure, it is usually necessary to first use ceramic raw materials to form a ceramic green body, and then sinter the ceramic green body through a sintering process to form a porous ceramic matrix. Then, thick film printing processes are used to print structures such as a heating film, an electrode film, and a encapsulation film on the surface of the ceramic matrix. During the printing process, it is necessary to perform positioning blind printing on the ceramic matrix. However, due to the sintering shrinkage characteristics of ceramics, it is very difficult to repeatedly and continuously find its position accurately during blind printing, making it difficult to achieve mass production.

[0003] In the prior art, the following two methods are generally used for positioning blind printing on a ceramic matrix:

[0004] The first is to adopt a single product separate positioning technical solution; as Figures 1 - 2 shown, the sintered ceramic matrix 10 completed according to the design size is respectively positioned and printed one by one through a jig 20. During the printing process, each ceramic matrix needs to be loaded and unloaded, with complex processes, cumbersome operations, and low production efficiency; moreover, during the sintering and forming process of the ceramic green body, dimensional shrinkage fluctuations will occur due to physical changes, and the error between the dimensional shrinkage rate during the ceramic sintering process and the dimensional tolerance of the jig is likely to cause printing position deviation, resulting in unstable printing quality.

[0005] The second is an entire plate product batch positioning technical solution; as Figures 3 - 4 shown, a positioning mark 50 with a V-shaped groove structure is provided on one side surface of the entire ceramic plate 30. After sintering, positioning and printing are performed with the positioning mark 50 as the positioning point. Similarly, due to dimensional shrinkage fluctuations caused by physical changes during the sintering and forming process of the ceramic green body, the position stability of the positioning mark 50 is poor. Using the positioning mark 50 as the positioning point, it is necessary to accurately position the ceramic plate every time printing is performed, and only one plate can be printed each time. The positioning operation is inconvenient, the positioning accuracy is low, and the production efficiency is not high. Summary of the Invention

[0006] In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide a blind printing method for ceramic products. The sintered ceramic plate is pre-cut according to a predetermined design size and specification to form standard ceramic blocks, and then blind printing is performed on the standard ceramic blocks according to the standard size. It is possible to simultaneously print multiple ceramic standard blocks at one time, with convenient operation, high printing accuracy, and the purpose of simplifying the production process, improving production efficiency, and enhancing the stability and reliability of printing quality.

This technical solution solves the problem that the positioning position is uncertain during printing due to the shrinkage fluctuation characteristics of the ceramic, and it is necessary to find the position for printing one by one. After the improved solution is pre-cut into standard sizes, it is not necessary to perform alignment for each printing, and multiple products can be printed simultaneously at one time. The alignment is accurate, and it is not necessary to perform alignment for each printing of a single product. Multiple products can be printed simultaneously at one time, with high efficiency; it solves the problems of low alignment accuracy and slow efficiency in batch blind printing of the whole ceramic plate.
