Description

Technical Field

[0001] The utility model relates to the technical field of artificial tooth repair processing, in particular to a cooling mechanism of a laser surface treatment machine dedicated to dentistry. Background Art

[0002] In recent years, with the continuous development of my country's economy and the continuous improvement of people's living standards, oral health problems have become an important factor affecting people's quality of life. Therefore, people are paying more and more attention to oral health problems. In particular, the problem of increasingly serious tooth loss rates among the middle-aged and elderly population has become increasingly prominent, leading to a continuous increase in people's demand for dentures. Common denture restorations on the market include all-metal crowns, all-ceramic crowns and porcelain crowns. The base of the porcelain crown is generally metal, and a layer of porcelain powder is melted on the surface of the metal base to achieve the same color as natural teeth. Since the materials of the metal base and porcelain powder are different and the physical properties are very different, their combination, that is, the metal-porcelain bonding performance, is particularly important, which directly affects the quality and service life of the denture. In severe cases, cracks and collapses of porcelain may occur, leading to restoration failure.

[0003] One of the most effective solutions is to enhance the metal-ceramic bonding strength through surface treatment. For example, the commonly used sandblasting treatment is to enhance the metal-ceramic bonding strength by increasing the surface roughness to increase the mechanical bonding strength. Our company creatively applies the roller surface laser texturing treatment technology to the surface treatment of dentures. For denture restorations, since the specific shape of the restorations varies from person to person, the restorations have the characteristics of complex curved surfaces and small structural dimensions, and a laser surface treatment machine dedicated to dentistry is required. When the restorations are laser treated, the surface needs to be cooled to a certain extent. However, when the surface is laser treated, it is easy to produce tiny particles that melt and solidify again and adhere to the surface of the restoration.

[0004] This case was created to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The utility model aims to provide a cooling mechanism for a laser surface treatment machine dedicated to dentistry to solve the problems raised in the above-mentioned background technology.

[0007] (II) Technical solution

[0008] To achieve the above objectives, the utility model is implemented through the following technical solutions: a cooling mechanism of a laser surface treatment machine specifically for dentistry, including an air nozzle and a workbench, a clamping mechanism is provided on the workbench, the air nozzle is arranged above the clamping mechanism, the air jet direction of the air nozzle is perpendicular to the laser emission direction, and an absorption mechanism is provided on the clamping mechanism.

[0009] Preferably, the absorption mechanism comprises a shell, the shell is cylindrical, an opening is provided on the arc-shaped side of the shell, the clamping mechanism is located inside the shell, and the clamping mechanism is exposed to the working range of the laser emitter and the gas nozzle through the opening.

[0010] Preferably, soft absorption layers are provided on both sides of the shell, and a fixed cover is provided outside the soft absorption layer.

[0011] Preferably, an air pipe is fixedly connected to the outside of the fixed cover, and the other end of the air pipe is connected to a telescopic mechanism, which is fixed on a workbench, and the air pipe is telescoped and extended by the telescopic mechanism, and the air pipe is connected to the inside of the fixed cover.

[0012] Preferably, fixing thorns are provided on both sides of the shell, and the fixing thorns penetrate into the soft absorption layer to fix the soft absorption layer.

[0013] (III) Beneficial effects

[0014] After adopting the above technical scheme, the utility model has the following advantages compared with the prior art: the utility model is a cooling mechanism of a laser surface treatment machine specially used for dentistry, and an absorption mechanism is directly arranged outside the clamping mechanism. When the metal denture restoration therein is subjected to laser treatment, under the action of the air nozzle and the laser emitter, the tiny particles produced on the surface of the restoration that are melted and solidified again are blown away from the surface of the restoration, and at the same time, the air pipe is evacuated to attract the tiny particles, so that the tiny particles adhere to the soft absorption layer under the influence of air pressure, and the soft absorption layer is easy to replace. It only needs to retract the air pipe under the action of the telescopic mechanism to drive the fixed cover to retract, and the soft absorption layer can be directly pulled out from the fixed thorns.
