Specifically, in the embodiment of the present application, the preset laser parameter may be a preset laser parameter that is adaptively set by a user through a configuration page, and the preset laser parameter may also be preset in advance by a system configuration personnel, it can be understood that based on different materials of the ceramic products, the ceramic products can be black pure zirconia ceramic products, vanilla pure zirconia ceramic products, and white iridium-doped zirconia ceramic products containing 94.5% zirconia and 5.5% iridium oxide, the embodiments of the present application preset corresponding preset laser parameters through the ceramic products of different materials, so as to generate the corresponding relationship between the ceramic products and the preset laser parameters, the corresponding preset laser parameters of different ceramic products can be the same or different, in the actual application process, the corresponding preset laser parameters can be automatically selected in real time according to the ceramic product.

Optionally, when the laser emitter is controlled to emit laser to the ceramic surface of the ceramic product along the preset mark pattern based on a preset laser parameter, based on that the ceramic product is in a nitrogen environment, the ceramic surface includes an emission region scanned by the laser, after the emission region receives the laser emitted by the laser emitter, the surface temperature rapidly rises, and then the zirconium oxide in the surface region and the nitrogen perform a nitridation reduction reaction based on a high temperature condition, so that gold zirconium nitride is generated, and then a gold preset mark pattern is formed.

Optionally, in this embodiment of the application, the temperature condition based on the nitridation reduction reaction is a high-temperature environment, and the ceramic surface is irradiated based on laser, so that the ceramic surface can be rapidly heated to the temperature condition required for the nitridation reduction reaction, and the efficiency of preparing the golden surface of the ceramic is improved.

It can be understood that, in the embodiment of the present application, based on providing a nitrogen environment for the ceramic product in advance, after the laser emitter emits laser light to the ceramic product, the ceramic surface of the ceramic product can be rapidly heated, and can directly perform a nitridation reduction reaction with the nitrogen, so that the efficiency of preparing the golden surface of the ceramic product is improved.

In this application embodiment, through providing the nitrogen gas environment for ceramic, and then through laser emitter based on predetermineeing laser parameter along predetermineeing mark pattern to ceramic surface emission laser for ceramic surface rapid heating up of ceramic, and then can directly take place the nitrogenize reduction reaction with nitrogen gas under the high temperature condition, and then form the golden coating including predetermineeing the mark pattern, realized having promoted the efficiency of ceramic golden surface preparation under the ceramic surface of ceramic need not in advance at ceramic surface addition colorant.

Alternatively, referring to fig. 4, based on the second embodiment, in order to improve the aesthetics of the ceramic golden surface preparation, the present application embodiment further provides a ceramic golden surface preparation method, where the S32 includes:

step S321, controlling the laser transmitter to transmit laser to the ceramic surface of the ceramic product along the preset mark pattern based on a first preset laser parameter, and acquiring the current scanned times;

step S323, when the current scanned number of times is consistent with the scanned number of times in the first preset laser parameter, controlling the laser emitter to emit laser to the ceramic surface of the ceramic product along the preset marking pattern based on a second preset laser parameter.

In an embodiment of the present application, the preset laser parameters include a first preset laser parameter and/or a second preset laser parameter.

Optionally, the first laser parameters include: the laser wavelength is 355nm, the laser pulse width is 10-15 ns, the power is 1.0-1.5W, the frequency is 100 KHz-200 KHz, the scanning speed is 50-150 mm/s, the focal position is-1-4 mm, the filling space is 0.01, and the scanning times are 3 times;

the second laser parameters include: the laser wavelength is 355nm, the laser pulse width is 10-15 ns, the power is 0.5-1.0W, the frequency is 200 KHz-250 KHz, the scanning speed is 50-150 mm/s, the focal position is-1-4 mm, the filling space is 0.01, and the scanning times are 4 times.

Optionally, the laser emitter is controlled to emit laser to the ceramic surface of the ceramic product along the preset marking pattern based on a first laser parameter so as to form an initial preset marking pattern on the ceramic surface, and then the laser emitter is controlled to emit laser to the ceramic surface of the ceramic product again along the preset marking pattern based on a second laser parameter so as to modify the initial preset marking pattern, so that the modified initial preset marking pattern is full in color, and the attractiveness of the preset marking pattern is improved.

It can be understood that, based on the power, the power refers to the energy of the laser beam emitted by the laser emitter, and in order to rapidly raise the temperature of the ceramic surface to the temperature condition required for the nitridation reduction reaction, based on this, the power of the first laser parameter set in the embodiment of the present application is greater than the power of the second laser parameter, so that when the laser is emitted to the ceramic surface based on the first preset laser parameter, the temperature of the ceramic surface can be rapidly raised to the temperature condition required for the nitridation reduction reaction. In addition, based on the frequency, the number of pulses emitted by the laser emitter per second is increased, the higher the frequency is in a unit time, the denser the points are, and conversely, the lower the frequency is, the looser the points are, the frequency in the second laser parameter is higher than the frequency of the first laser parameter, so that the density degree of the points on the ceramic surface can be increased, and the preset mark pattern on the ceramic surface is smoother.

Optionally, before preparing the golden surface of the ceramic product, the first preset parameter and the second preset parameter may be obtained by a user adaptively setting the first preset laser parameter and the second preset parameter through a configuration page, and the user sets two groups of laser parameters through the configuration page and may simultaneously set a scanning order of the laser parameters; in addition, the first preset laser parameter and the second preset laser parameter can also be preset by a system configuration personnel in advance.

Optionally, after receiving the first preset laser parameter and the second preset laser parameter, the control system controls the laser emitter to emit laser to the ceramic surface according to the first preset laser parameter, records the current scanning frequency of the laser emitter when emitting laser to the ceramic surface according to the first preset laser parameter, switches the current laser parameter to the second preset laser parameter when the current scanning frequency reaches the scanning frequency in the first preset laser parameter, and then controls the laser emitter to emit laser to the ceramic surface according to the second preset laser parameter, so as to form a full golden preset mark pattern on the ceramic surface. For example, the number of scanning times in the first preset laser parameter is 3, and the number of currently scanned times of the laser emitter is recorded as 3, so that the laser emitter is directly controlled to emit laser to the ceramic surface based on the second preset laser parameter.

In this application embodiment, through setting up first laser parameter of predetermineeing and the second laser parameter of predetermineeing, through with first laser parameter of predetermineeing with the cooperation of the second laser parameter of predetermineeing uses, realized ceramic surface forms the golden preset mark pattern of full gold, when promoting the efficiency on preparation ceramic golden surface, has improved the aesthetic property on preparation ceramic golden surface, satisfies the user to the demand of aesthetic property.
