[0030] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] Figure 1 The implementation process of the surface grinder control method for ceramics according to the embodiment of the present invention is shown; please refer to Figure 1 ;

[0032] After long-term practice, it is found that the existing surface grinders for ceramic grinding usually grind ceramic parts through one-time processing or manual operation; due to the material characteristics of ceramics, it is easy to appear that the grinding temperature is too high during ceramic processing, which may cause plastic deformation and cause cracks at the grain boundary, thereby causing material breakage. Therefore, how to control the surface grinder to avoid the breakage of ceramic parts is an urgent problem to be solved in this industry. In view of this, the present invention provides a tightening equipment technical method, device, equipment and storage medium to at least solve the above technical problems existing in the prior art.

[0033] According to a first aspect of the present invention, a control method for a surface grinder for ceramics is provided, the method comprising: step 101, obtaining first material information corresponding to the grinding tool and second material information corresponding to the ceramic part; step 102, obtaining the spindle speed corresponding to the surface grinder, and determining a temperature change curve corresponding to the ceramic part and the spindle speed of the surface grinder based on the first material information, the second material information and the spindle speed; step 103, determining a safe temperature range corresponding to the ceramic part based on the second material information, the safe temperature range including a maximum temperature and a minimum temperature; step 104, determining a first speed corresponding to the maximum temperature and a second speed corresponding to the minimum temperature in the temperature change curve according to the safe temperature range; step 105, generating a first control instruction according to the first speed and the second speed, the first control instruction being used to instruct the surface grinder to perform pulse grinding at the first speed and the second speed.

[0034] The present invention predicts the temperature change curve corresponding to the spindle speed through the first material information, the second material information and the spindle speed. The temperature change curve can be used to determine the safe temperature range corresponding to the safe processing of ceramic parts while ensuring the minimum accuracy. The first speed and the second speed corresponding to the maximum temperature and the minimum temperature are determined through the safe temperature range. Then, the control instructions are generated with the first speed and the second speed to control the surface grinder to perform pulse grinding, so that the surface grinder can ensure accuracy while avoiding excessive temperature of the ceramic parts, which will cause plastic deformation of the ceramic parts and induce cracks at the grain boundaries, and finally lead to the rupture of the ceramic parts.

[0035] Step 101, obtaining first material information corresponding to the abrasive tool and second material information corresponding to the ceramic part;

[0036] In step 101 of the present invention, the first material information may be characteristic information corresponding to the characteristics of the specific constituent materials of the grinding tool. Preferably, the series include aluminum oxide series, silicon nitride series, titanium boride series and metal ceramics. The second material information may be characteristic information corresponding to the characteristics of the specific constituent materials of the ceramic part. Among them, the first material information includes material composition information and the maximum heat tolerance corresponding to the material. The second material information includes material composition information, the maximum heat tolerance corresponding to the material and the target accuracy. By acquiring the first material information and the second material information, the subsequent prediction of the temperature change curve can be made more accurate, thereby avoiding the cracking of the ceramic part or the grinding tool during grinding as much as possible.

[0037] Step 102, obtaining a spindle speed corresponding to the surface grinder, and determining a temperature variation curve of the ceramic part corresponding to the spindle speed of the surface grinder based on the first material information, the second material information and the spindle speed;

[0038] In step 102 of the present invention, the temperature calculation of the abrasive tool during the grinding process of the grinder is a complex process, which involves multiple factors. Therefore, by collecting the data set to establish a temperature curve prediction model, it can be more accurate and faster than manually calculating the temperature change curve. Specifically, the model training includes obtaining training samples, and the training samples include training parameters corresponding to the first material information, the second material information and the spindle speed; wherein the training parameters corresponding to the first material information can be the specific component material corresponding to the ceramic abrasive tool, the training parameters corresponding to the second material information can be the component material corresponding to the ceramic part, and the training parameters corresponding to the spindle speed can be the grinding speed and grinding depth of the spindle within a specified time; the training samples also include output samples, and the output samples are identified by the temperature sensor, and the temperature changes corresponding to the change of the spindle speed, and the temperature change curve is used as the output sample. Specifically, the training samples in the training parameters can be the speed time series data of the spindle speed increasing with time when the first material information, the second material information and the grinding depth are determined; the output samples can be the temperature time series data increasing with time. The recurrent neural network (RNN) model is trained through training samples to obtain a temperature curve prediction model; the first material information, the second material information and the spindle speed are input into the temperature curve prediction model to obtain the temperature change curve corresponding to the ceramic part and the spindle speed. The temperature change curve refers to the curve in which the temperature changes with time series. Among them, the RNN model is suitable for processing and predicting the time dependency and timing information in the sequence data, and the RNN can remember the previous information and use the information to make predictions or decisions in the subsequent time steps. Therefore, it can better adapt to the prediction of the temperature curve.

[0039] Step 103, determining a safe temperature range corresponding to the ceramic component based on the second material information, wherein the safe temperature range includes a maximum temperature and a minimum temperature;

[0040] In step 103 of the present invention, the bearing temperature corresponding to the ceramic part is determined based on the second material information. The bearing temperature can be the temperature that the ceramic part can withstand. When the temperature is higher than the bearing temperature, the ceramic part may break due to high temperature. The bearing temperature is determined as the highest temperature in the safe temperature range; thereby, the ceramic part will not break due to high temperature during the grinding process, thereby reducing the loss rate of the ceramic part during the processing. The minimum precision corresponding to the ceramic part is obtained, and the minimum temperature corresponding to the safe temperature range is determined according to the minimum precision; the minimum precision is the surface precision required for the surface of the ceramic part during the processing of the ceramic part. The surface precision can be used to determine the minimum grinding speed of the mold corresponding to the surface precision. The minimum grinding speed can be used to determine that the temperature of the surface of the ceramic part when grinding at the minimum grinding speed is the minimum temperature. Specifically, the temperature corresponding to the moment when the speed is accelerated to the minimum grinding speed is the minimum temperature.

[0041] Among them, regarding the determination of the maximum temperature, the bearing temperature of the ceramic part is generally lower than the bearing temperature of the mold; however, in ceramic grinding, there is also a situation where a ceramic mold is used to grind the ceramic part; the mold is a ceramic mold; correspondingly, determining the safe temperature range corresponding to the ceramic part includes: determining the bearing temperature corresponding to the ceramic mold based on the first material information; when the bearing temperature is lower than the highest temperature in the safe temperature range, the bearing temperature is determined as the highest temperature in the safe temperature range. Thus, when the ceramic mold is used, it is ensured that the maximum temperature is prevented from being higher than the ceramic mold, causing the ceramic mold to break due to high temperature. The bearing temperature refers to the highest temperature that the ceramic mold can withstand on the grinding stone. When the temperature is higher than the bearing temperature, the ceramic mold may break due to high temperature. Among them, to avoid excessive speed difference, the minimum temperature is within a specified proportion of the maximum temperature, specifically, it can be within 80% of the maximum temperature to avoid unnecessary damage to the ceramic part caused by large temperature difference changes. Therefore, when the minimum temperature is lower than 80% of the maximum temperature, 80% of the maximum temperature can be used as the minimum temperature of the ceramic mold.

[0042] Step 104, based on the safe temperature range, a first speed corresponding to the highest temperature and a second speed corresponding to the lowest temperature in the temperature change curve can be determined; Step 105, a first control instruction is generated based on the first speed and the second speed, and the first control instruction is used to instruct the surface grinder to perform pulse grinding at the first speed and the second speed.

[0043] In steps 104-105 of the present invention, the first speed corresponding to the highest temperature and the second speed corresponding to the lowest temperature can be determined through the temperature change curve and the spindle speed curve corresponding to the temperature change curve; the cycle duration corresponding to the mold is determined according to the first speed and the second speed; the cycle duration can be the time required for the spindle speed to be reduced to the second speed, or it can be the cycle duration set by the staff, such as 30s. A first control instruction is generated according to the cycle duration, the first speed and the second speed, that is, a pulsed working instruction for adjusting the first speed to the second speed and the second speed to the first speed in a cycle of 30 seconds. Among them, when the second speed is greater than or equal to the first speed, it is determined that there is a problem with the process, and the fault information is sent to the management machine to prompt the administrator to handle it in time.

[0044] In addition, when the rotation speed is too high, the temperature rise cannot be suppressed by pulse control; the surface grinder in the present invention is also provided with a visual recognition device, which can cooperate with the visual recognition device to further detect the ceramic grinding tool and the ceramic part, and can make corresponding instructions in the first time when the ceramic is found to be cracked. Specifically, in one embodiment, the surface grinder is also provided with a visual recognition device, and the visual recognition device is used to identify the surface temperature and the first surface image of the ceramic part; the visual recognition device is used to identify the surface temperature and the first surface image of the ceramic grinding tool; the method also includes: obtaining the first visual recognition information corresponding to the ceramic part, and the first visual recognition information refers to the information obtained by the visual recognition device to identify the surface grinder. Among them, the first visual recognition information includes the first temperature information and the first surface image; the first temperature information refers to the temperature of the ceramic part; the first surface image refers to the image of the ceramic part; correspondingly, when the first temperature information indicates that the temperature is greater than the maximum temperature and / or when the first surface image indicates that the surface of the ceramic part is broken, a second control instruction is generated, and the second control instruction is used to control the surface grinder to raise the ceramic part. When the situation is the former, the second control instruction is used to control the surface grinder to raise the ceramic part for a specified time to reduce the temperature of the ceramic part to ensure that the ceramic part will not crack, and then lower it after a specified time, wherein the specified temperature can be the time when the ceramic part cools to the lowest temperature. When the situation is the latter, the second control instruction is used to control the surface grinder to raise the ceramic part while issuing an alarm instruction to prompt the administrator to repair or replace it.

[0045] Further, when the abrasive tool is a ceramic abrasive tool, and the ceramic abrasive tool is subjected to a second ceramic part with a temperature, in one embodiment, the surface grinder is also provided with a visual recognition device, and the method further includes: obtaining second visual recognition information corresponding to the ceramic abrasive tool, the second visual recognition information including second temperature information and second surface image; the second temperature information refers to the temperature of the ceramic abrasive tool; the second surface image refers to the image of the ceramic abrasive tool; correspondingly, when the second temperature information represents a temperature greater than the maximum temperature and / or when the second surface image represents a surface crack of the ceramic abrasive tool, a third control instruction is generated, and the third control instruction is used to control the surface grinder to raise the ceramic abrasive tool. When the situation is the former, the third control instruction is used to control the surface grinder to raise the ceramic abrasive tool for a specified time to reduce the temperature of the ceramic abrasive tool to ensure that the ceramic abrasive tool will not be cracked, and to lower it after the specified time, wherein the specified temperature can be the time when the ceramic abrasive tool cools to the lowest temperature. When the situation is the latter, the third control instruction is used to control the surface grinder to raise the ceramic abrasive tool while issuing an alarm instruction to prompt the administrator to repair or replace it.
