However, although the method is simple to control, the blade is abraded in the cutting process, and the outer diameter of the blade is reduced after the blade is abraded, so that the linear speed of the blade in the cutting process is changed, and the processing quality of the new blade and the old blade to-be-processed workpieces is unstable; meanwhile, the user can replace the blade too early for ensuring the quality of the workpiece to be processed after processing, so that the processing cost is increased and waste is caused.
Therefore, how to ensure the processing quality of the workpiece to be processed by controlling the rotating speed of the blade is a difficult problem to be solved urgently in the production process in the field of semiconductors at present.
Based on the above phenomena, embodiments of the blade rotation speed control method of the present invention are proposed. It should be noted that, although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different than that shown or described herein.
The first embodiment: referring to fig. 2 and fig. 3, fig. 2 is a schematic flow chart of a first embodiment of a method for controlling a blade rotation speed according to the present invention, and fig. 3 is a schematic flow chart of an application of the first embodiment of the method for controlling a blade rotation speed according to the present invention. The invention provides a method for controlling the rotating speed of a blade, which comprises the following steps:
step S100, determining the predicted abrasion loss of the blade for cutting the workpiece to be processed.
It should be noted that, in this embodiment, because the dicing machine is used for dicing a workpiece to be processed, after a period of dicing processing, the used blade may be worn to different degrees, in consideration of the measurement cost and the actual processing process, it is reasonable to actually measure the blade at specific time intervals, and adjust the rotation speed of the blade according to the measured data, and in a non-actual measurement period, the terminal performs a simulation operation on the blade to obtain the predicted wear amount of the blade, so that the terminal subsequently adjusts the rotation speed of the blade based on the predicted wear amount.
And the terminal carries out simulation operation on the blade for carrying out cutting machining on the workpiece to be machined, so that the predicted wear amount of the blade is obtained, and the terminal can adjust the rotating speed of the blade based on the predicted wear amount subsequently.
Step S200, determining the predicted radius of the blade based on the predicted abrasion loss.
In this embodiment, the initial radius of the blade when the blade is not put into use can be known according to the specification of the blade applied to the dicing process, and after the predicted wear amount of the blade is obtained, the terminal can obtain the predicted radius of the blade according to the initial radius and the predicted wear amount of the blade.
After the terminal obtains the predicted abrasion loss of the blade through simulation operation, the initial radius of the blade is obtained, and then the predicted radius of the blade is obtained according to the predicted abrasion loss and the initial radius.
Specifically, for example, the terminal determines that the predicted wear amount of the blade is 5um, and obtains an initial radius of 58mm according to a specification of a blade of a1, the terminal determines that the predicted radius of the blade is 57.995 mm.
And step S300, adjusting the rotating speed of the blade based on the predicted radius.
It should be noted that, in the present embodiment, the rotation speed of the blade is determined according to the rotation speed formula v = rw, that is, according to the predicted radius of the blade and the linear speed required in the dicing process.
After the terminal determines the predicted radius of the blade, simulation operation is carried out according to the predicted radius and the linear speed of the blade required by cutting aiming at different workpieces to be processed, the rotating speed required by the blade in actual cutting is obtained, and the blade is adjusted based on the rotating speed.
In the embodiment, the terminal carries out simulation operation on the blade for carrying out cutting machining on the workpiece to be machined, so that the predicted wear amount of the blade is obtained, and the terminal subsequently adjusts the rotating speed of the blade based on the predicted wear amount; the method comprises the steps that after a terminal obtains a predicted abrasion loss of a blade through simulation operation, an initial radius of the blade is obtained, and then the predicted radius of the blade is obtained according to the predicted abrasion loss and the initial radius; after the terminal determines the predicted radius of the blade, simulation operation is carried out according to the predicted radius and the linear speed of the blade required by cutting aiming at different workpieces to be processed, the rotating speed required by the blade in actual cutting is obtained, and the blade is adjusted based on the rotating speed.
Therefore, the blade rotating speed control method provided by the invention can correspondingly adjust the rotating speed of the blade according to the abrasion loss of the blade used for cutting the workpiece to be processed, ensures that the linear speed of the blade in cutting process always meets the processing requirement, ensures that the blades with different old and new degrees can reach the processing quality with the same standard, and has extremely high practicability and application value.
Further, a second embodiment of the method for controlling the rotational speed of the blade according to the present invention is proposed based on the first embodiment of the method for controlling the rotational speed of the blade described above.
In a second embodiment of the method for controlling the rotational speed of the blade according to the present invention, the step S100 may include:
and step S101, determining a preset wear coefficient of the blade, and determining the predicted wear amount based on the preset wear coefficient.
It should be noted that, in this embodiment, the preset wear coefficient is a parameter involved in the calculation process of determining the predicted wear amount of the blade by the terminal, and is used for measuring the wear amount of the blade caused by a unit dicing distance.
The method comprises the steps that a terminal determines a preset wear coefficient corresponding to a blade and used for measuring the wear caused by a unit cutting distance, operation is carried out based on the preset wear coefficient to obtain the predicted wear of the blade, and after the preset wear coefficient of the blade is determined, the predicted wear of the blade is determined according to the preset wear coefficient, the cutting processing length and the initial radius of the blade.
Further, in a possible embodiment, the step S101 may include:
step S1011, carrying out a cutting test on the blade based on a preset rotating speed to obtain the cutting linear speed of the blade.
It should be noted that, in this embodiment, the preset rotation speed is a rotation speed preset by a user and used for performing a dicing test on the blade.
And the terminal carries out the cutting test on the blade by adopting the rotating speed which is preset by the user and is used for the cutting test, so as to obtain the cutting linear speed of the blade in the cutting test.
Specifically, for example, the terminal performs a cutting experiment on the blade, measures a measured wear amount caused by the blade after the blade passes through a cutting distance of 3 to 10 meters at a specific rotating speed, and determines a preset wear coefficient of the blade according to the measured wear amount; or the terminal acquires a historical wear data comparison table corresponding to the specification of the blade and determines the current preset wear coefficient of the blade.
Step S1012, determining the preset wear coefficient according to the dicing line speed.
And after the terminal obtains the cutting linear speed of the blade, determining the wear coefficient of the blade according to the cutting linear speed based on the contrast relation between the linear speed and the wear coefficient.
Specifically, for example, the preset wear coefficient may be determined in a dicing experiment by the following formula:
a preset wear coefficient F = (cutting length L/wear amount W) × 0.75+ original wear coefficient Fo × 0.25;
wherein the cutting length L is the total cutting length from the last wear measurement in meters;
the wear amount W is the total wear amount since the last wear measurement, W = (last wear measurement blade outer diameter + present wear measurement under-blade outer diameter) × pi/2, unit mm.
In addition, the initial value of the wear coefficient F can be inquired in the system according to the model and the material of the blade, and if relevant data exist, the initial value of the wear coefficient F is set as the initial value of F; if no correlation data exists, the F initial value is set to 0.
The related historical wear data comparison table is as follows:
| blade type | Material 1 | Material 2 | Material 3 | The material quality. | Material Fn |
| Coefficient of wear | F1 | F2 | F3 | F...... | Fn |
In this embodiment, a preset wear coefficient corresponding to the blade and used for measuring the wear caused by a unit dicing distance is determined by the terminal, an operation is performed based on the preset wear coefficient to obtain a predicted wear amount of the blade, and after the preset wear coefficient of the blade is determined, the predicted wear amount of the blade is determined according to the preset wear coefficient, the dicing processing length, and the initial radius of the blade.
Thus, the embodiment provides the implementation steps for determining the predicted wear amount of the blade and the related operation process, and improves the practicability of the blade rotating speed control method.
Further, a third embodiment of the method for controlling the rotational speed of the blade according to the present invention is proposed based on the first embodiment of the method for controlling the rotational speed of the blade described above.
In a third embodiment of the method for controlling a rotational speed of a blade of the present invention, the method for controlling a rotational speed of a blade further includes:
and S400, performing abrasion measurement on the blade based on a preset measurement period to obtain a measurement result.
It should be noted that, in this embodiment, the preset measurement period is a period preset by a user and used for measuring the wear amount of the blade for dicing, and the obtained measurement result is used for comparing with the predicted wear amount to obtain a comparison result, so that the rotation speed of the blade is controlled and adjusted more accurately according to the comparison result.
And the terminal measures the abrasion loss of the blade for the cutting processing based on the period of measuring the abrasion loss preset by the user to obtain the actual abrasion loss of the blade.
Specifically, for example, the terminal performs a wear measurement after a blade for dicing is subjected to dicing for a length of 50 meters in accordance with a measurement instruction actively issued by the user to determine an actual wear amount of the blade at that time.
And S500, determining the actual radius of the blade according to the measurement result.
And the terminal obtains the actual abrasion quantity of the blade after the terminal carries out abrasion measurement on the blade for the cutting process, and further determines the actual radius of the blade according to the actual abrasion quantity and the initial radius of the blade.
Specifically, for example, the terminal determines that the actual wear amount of the blade is 6um, and obtains an initial radius of the blade as 5mm according to a specification of the blade as a1, the terminal determines that the predicted radius of the blade is 4.994 mm.
In this embodiment, the step S300 includes:
and 301, correcting the predicted radius based on the actual radius to obtain a corrected radius.
It should be noted that, in this embodiment, since the terminal performs wear measurement on the blade for dicing machining at the time point preset by the user, and determines the actual radius of the blade according to the actual wear amount of the blade, it can be understood that the predicted radius is corrected based on the actual radius, and the actual radius is used as the correction radius for adjusting the rotational speed of the blade, so that the rotational speed of the blade can be controlled and adjusted more accurately.
The terminal measures the abrasion of the blade for the cutting machining at a time node preset by a user, determines the actual radius of the blade according to the actual abrasion of the blade, and corrects the predicted radius based on the actual radius to obtain a corrected radius for adjusting the rotating speed of the blade.
And step 302, adjusting the rotating speed of the blade based on the correction radius.
And after the terminal obtains the correction radius of the blade, adjusting and controlling the rotating speed of the blade according to the correction radius so as to enable the cutting machining of the workpiece to be machined to reach the actual production requirement standard.
In the embodiment, the terminal measures the abrasion loss of the blade for the cutting machining based on the period of measuring the abrasion loss preset by the user to obtain the actual abrasion loss of the blade; after the terminal obtains the actual abrasion loss of the blade, the terminal further determines the actual radius of the blade according to the actual abrasion loss and the initial radius of the blade; the terminal corrects the predicted radius based on the actual radius to obtain a corrected radius for adjusting the rotating speed of the blade; and after the terminal obtains the correction radius of the blade, adjusting and controlling the rotating speed of the blade according to the correction radius so as to enable the cutting machining of the workpiece to be machined to reach the actual production requirement standard.
Therefore, the embodiment combines two modes of predicting the wear loss and periodically detecting the wear loss to determine the wear loss of the blade, and can ensure the accuracy of the measurement result of the wear loss while effectively controlling the measurement cost, thereby ensuring the accuracy of the control and adjustment of the rotating speed of the blade and further improving the practicability of the method for controlling the rotating speed of the blade.
Further, a fourth embodiment of the method for controlling the rotational speed of the blade according to the present invention is proposed based on the first embodiment of the method for controlling the rotational speed of the blade described above.
In the fourth embodiment of the method for controlling the rotational speed of the blade according to the present invention, after the step S500, the method further includes:
step S600, comparing the predicted radius with the actual radius to obtain a comparison result.
It should be noted that, in this embodiment, because the wear cost generated by the actual measurement of the wear amount and the deviation between the predicted wear amount and the actual wear amount need to be considered comprehensively, after the terminal performs wear measurement on the blade based on the preset measurement period of the user, the actual radius of the blade is obtained, the actual radius is compared with the predicted radius obtained by the terminal simulation operation, so as to obtain the deviation between the simulation operation and the actual measurement, and further adjust the preset measurement period.
The terminal carries out abrasion measurement on the blade, determines the actual radius of the blade, and then compares the actual radius with the predicted radius obtained by the terminal through simulation operation aiming at the blade to obtain a comparison result.
Step S700, adjusting the preset measurement period based on the comparison result and a preset standard.
It should be noted that, in the present embodiment, the preset criterion is a criterion preset by the user for measuring a deviation between the predicted wear amount and the actual wear amount of the blade.
After the terminal obtains the comparison result of the actual wear loss and the predicted wear loss of the blade, the comparison result is compared with a standard which is preset by a user and used for measuring the deviation of the predicted wear loss and the actual wear loss of the blade to obtain a deviation result, and the measurement period of the blade is adjusted according to the deviation result, so that the predicted wear loss obtained by the terminal through simulation operation on the blade is closer to the actual wear loss.
Further, in a possible embodiment, the step S700 may include:
step 701, if the comparison result exceeds the preset standard, shortening the preset measurement period.
After the terminal compares the comparison result with a standard for measuring the deviation between the predicted wear amount and the actual wear amount of the blade, if the comparison result exceeds the standard, the terminal correspondingly shortens the preset measurement period for measuring the wear of the blade.
Specifically, for example, a user sets a standard for measuring a deviation between a predicted wear amount and an actual wear amount of a blade to be 3um in advance, if an actual wear amount obtained after a terminal performs wear measurement on the blade is 10um, and a predicted wear amount determined by the terminal performing simulation operation on the blade is 5um, a deviation between the predicted wear amount and the actual wear amount is 5um, and exceeds the preset standard of 3um, the terminal correspondingly changes a preset measurement period a for performing wear measurement every 10 meters of cutting processing into a preset measurement period B for performing wear measurement every 5m of cutting processing, so as to ensure that a result of simulation operation performed on the blade by the terminal is closer to an actual situation.
Step 702, if the comparison result is lower than the preset standard, the preset measurement period is prolonged.
After the terminal compares the comparison result with a standard for measuring the deviation between the predicted wear amount and the actual wear amount of the blade, if the comparison result is lower than the standard, the terminal correspondingly prolongs a preset measurement period for performing wear measurement on the blade.
Specifically, for example, a user sets a standard for measuring a deviation between a predicted wear amount and an actual wear amount of a blade to be 3um in advance, if an actual wear amount obtained by a terminal performing wear measurement on the blade is 5um, and a predicted wear amount determined by the terminal performing analog operation on the blade is 4um, a deviation between the predicted wear amount and the actual wear amount is 1um, which is lower than the preset standard of 3um, a preset measurement period a in which the terminal performs wear measurement every 10 meters of cutting processing is correspondingly changed to a preset measurement period C in which wear measurement is performed every 20m of cutting processing, so as to reduce measurement cost caused by wear measurement on the blade.
Further, in one possible embodiment, the wear measurement comprises: in the step S400, the step of performing wear measurement on the blade based on a preset measurement period includes:
step S401, non-contact wear measurement is conducted on the blade based on a preset measurement period.
In the present embodiment, the non-contact wear measurement is a measurement method for measuring wear of a blade used for dicing without contacting a jig for fixing a workpiece to be processed, and the measurement method generally measures the blade through a correlation optical fiber, and is simple in operation, low in measurement cost, and a commonly used wear measurement means.
And the terminal measures the abrasion of the blade in a non-contact abrasion measuring mode based on the period which is preset by the user and used for measuring the abrasion of the blade for the cutting process.
And S402, if the cutting process meets the preset processing conditions, performing contact wear measurement on the blade.
It should be noted that, in the present embodiment, the preset machining conditions include specific machining conditions such as replacement of a blade for dicing machining, replacement of a workpiece to be machined, and change of a simulation algorithm involved in determination of the predicted wear amount, and it is understood that under the specific machining conditions, the predicted wear amount and the actual wear amount of the blade may have a large deviation, and therefore, the accuracy of the measurement result regarding the actual wear amount of the blade is improved by using contact wear measurement; the contact wear measurement is a measurement method for measuring the wear of a blade under the condition that the blade for cutting machining is in contact with a jig for fixing a workpiece to be machined, the measurement method is relatively complex and tedious in operation and high in measurement cost, but the measurement result is high in precision and is generally applied under specific machining conditions.
The terminal takes contact wear measurements for the blade under certain processing conditions where the predicted wear amount of the blade may deviate significantly from the actual wear amount.
In this embodiment, after the terminal measures the wear of the blade and determines the actual radius of the blade, the actual radius is compared with a predicted radius obtained by the terminal through simulation operation on the blade, so as to obtain a comparison result; after obtaining a comparison result of the actual wear loss and the predicted wear loss of the blade, the terminal compares the comparison result with a standard which is preset by a user and used for measuring the deviation between the predicted wear loss and the actual wear loss of the blade to obtain a deviation result, and adjusts the measurement period of the blade according to the deviation result so as to enable the predicted wear loss obtained by the terminal through simulation operation on the blade to be closer to the actual wear loss; the method comprises the steps that a terminal measures abrasion of a blade in a non-contact abrasion measuring mode based on a period which is preset by a user and used for measuring abrasion of the blade for cutting machining; the terminal takes contact wear measurements for the blade under certain processing conditions where the predicted wear amount of the blade may deviate significantly from the actual wear amount.
In this way, by adjusting the measurement period and the measurement mode for measuring the wear amount of the blade, the measurement cost can be better controlled while the accuracy of determining the wear amount of the blade is satisfied, and the practicability of the method for controlling the rotating speed of the blade is further improved.
