Description

Technical Field

[0001] The invention relates to the technical field of glaze repair, in particular to a laser glaze repair machine for ceramics. Background Art

[0002] Porcelain is a ceramic product made of porcelain clay through molding, drying, firing and other processes. Since porcelain is easily damaged, it needs to be repaired. Porcelain glaze repair is a technology to repair and restore damage to the surface of porcelain. However, the existing repair method is prone to color difference between the repair pigment and the porcelain itself, thereby reducing the quality of the repaired porcelain, and causing the hardness of the repaired area to not match the hardness of the porcelain itself, which can easily lead to the shedding of the repair pigment.

[0003] In the prior art, laser irradiation of glaze strips is usually used to melt the glaze strips on the surface of the porcelain, and then sandpaper is used to polish after drying by light. For example, Chinese patent publication number: CN118084537A discloses a laser glaze repair process, which includes the following steps: step one, preparing porcelain pieces; step two, preparing glaze strips; step three, laser irradiation; step four, glaze repair; step five, quality inspection; wherein in the above step one, the porcelain to be glazed is selected, and the clean and flat unglazed area is ensured; wherein in the above step two, the porcelain glaze selected in step one is selected, and then the selected glaze is made into a glaze strip suitable for use, and it is heated to reach a uniformly melted state; wherein in the above step three, the glaze strip is melted in the unglazed area of ​​the porcelain by laser irradiation, so that the glaze repair part is integrated with the porcelain surface; the occurrence of the glaze strip remaining at the repair position of the porcelain by laser not only avoids color difference, but also uses raw materials of the same hardness for repair, reduces the shedding of the repair material, and thus improves the quality of the repaired porcelain.

[0004] In this scheme, the glaze strip is melted in the unglazed area of ​​the porcelain, so that the glaze repair part is integrated with the porcelain surface. After the glaze repair part cools down, the glaze repair area is carefully polished with a grinder to make the glaze repair and the original glaze surface naturally transition. The glaze repair part is then melted with laser irradiation, and then cooled to make the glaze present a uniform and smooth surface. However, this process has the problem that the glaze strip does not flow along the predetermined route after melting, so that the glaze surface of the part that needs to be repaired is thinner, and the glaze surface of the part that does not need to be repaired is thicker. In addition, the irregular liquid glaze needs to be polished again, and each polishing will damage the original glaze surface. The process is not very reasonable, and this scheme is also prone to raised glaze spots. Summary of the invention

[0021] The laser glaze repairing machine for ceramics is provided with a track-changing glaze blowing component and a laser emitting component. The glaze strip can be placed in a glaze strip box. When repairing porcelain, the position of the porcelain to be repaired is aligned with the laser emitting component. When the laser emitting component irradiates the glaze strip, the heat of the laser can pass through the irradiation hole and the flow channel, so that the melted glaze strip drips onto the porcelain. At the same time, the air inlet pipe is connected to the high-pressure air pump. The high-pressure gas gathers near the high-pressure gas nozzle and surrounds the outer circle of the laser light. The converged airflow can blow down the melted glaze liquid, so that the glaze liquid is diffused to all sides when it drips on the porcelain. The diffused glaze liquid can form an arc-shaped coating on the surface of the porcelain. At the same time, the airflow with high temperature can also correct the shape of the glaze liquid and dry the glaze liquid. After the glaze liquid is flattened by the airflow, the laser emitting component is controlled to switch the light source, so that the drying light source irradiates the glaze repairing position, and the glaze liquid can solidify quickly, thereby avoiding various problems such as glaze liquid imbalance, convex points, roughness, etc. that occur during the existing laser glaze repair. This laser irradiation plus high-pressure blowing can ensure the smoothness of the glaze surface and reduce the number of polishing times.

[0022] The ceramic laser glaze repair machine is equipped with an angle adjustment mechanism. When the wheel rotates, it can change the glaze blowing angle of the laser emitting component, and can achieve multiple angle changes, which can adapt to porcelain with different curvatures. The screw drive component can also adjust the distance between the laser emitting component, the glaze strip box and the porcelain, and can change the diffusion change and area change of the glaze liquid. After the glaze strip at one position is melted, the laser emitting component can be moved and then used to irradiate another part of the glaze strip. The glaze strip can be used to the maximum extent, and the effect of automatic glaze repair can be achieved.

[0023] The laser glaze repair machine for ceramics is provided with a protective bottom shell. When the angle adjustment mechanism changes the irradiation angle of the laser emitting component, the angle of the protective bottom shell can also be controlled to change the angle of the porcelain. The angle of the porcelain can change with the angle of the laser emitting component, or change in the opposite direction, or change dynamically, and can adapt to porcelain of various curvatures.

[0024] The laser glaze repair machine for ceramics is equipped with a clamping mechanism. The two clamping mechanisms can clamp the porcelain when the cylinder is extended. The servo motor B can rotate the porcelain. The linear drive block B can make the porcelain follow the movement of the laser emitting component. Combined with the movement of the angle adjustment mechanism, the freedom of movement of the XYZ axis can be realized, and the freedom of angle change can be achieved. The glaze repair effect is better and no manual assistance is required. BRIEF DESCRIPTION OF THE DRAWINGS

The high-pressure gas gathers near the high-pressure gas nozzle 9 and surrounds the outer circle of the laser light. The converged airflow can blow down the melted glaze liquid, so that when the glaze liquid drops on the porcelain, it is diffused to the surroundings by the wind. The diffused glaze liquid can form an arc-shaped coating on the surface of the porcelain. At the same time, the high-temperature airflow can also correct the shape of the glaze liquid and dry it. The glaze liquid is melted. After the glaze liquid is spread by the airflow, the laser emitting component 8 is controlled to switch the light source so that the drying light source irradiates the glaze repairing position, and the glaze liquid can solidify quickly. The rotating wheel 601 can change the glaze blowing angle of the laser emitting component 8 when rotating, and multiple angle changes can be achieved, which can adapt to porcelain with different curvatures. The screw drive component 604 can also adjust the distance between the laser emitting component 8, the glaze strip box 701 and the porcelain, which can change the diffusion change and area change of the glaze liquid. After the glaze strip at one position is melted, the laser emitting component 8 can be moved and then used to irradiate another part of the glaze strip, which can maximize the use of the glaze strip. In combination with the movement of the angle adjustment mechanism 6, when the angle adjustment mechanism 6 changes the irradiation angle of the laser emitting component 8, the angle of the protective bottom shell 3 can also be controlled to change the angle of the porcelain. The angle of the porcelain can change with the angle change of the laser emitting component 8, or it can change inversely, or dynamically cooperate with the change, which can achieve multi-degree-of-freedom, intelligent and automated repair of porcelain.
