Technical Field

[0001] The present application relates to the technical field of height measurement and adjustment, and in particular to a non-contact height measurement and adjustment method and device for a dicing machine blade. Background Art

[0002] With the refinement and miniaturization of electronic devices, the cutting process requirements are getting higher and higher, especially in high-precision cutting scenarios such as chip manufacturing. As a commonly used high-precision cutting equipment, the performance and accuracy of the dicing machine directly affect the quality and yield of the cut products. The traditional dicing machine blade height adjustment method mostly adopts contact measurement means, which not only has low measurement efficiency, but also easily causes loss due to the contact between the blade and the measuring device, affecting the blade life and cutting effect. At the same time, the existing non-contact height measurement technology has limited height measurement accuracy and response speed when facing complex cutting requirements, and it is difficult to meet the requirements of high-speed and precise cutting. In addition, with the diversification of cutting materials and the complexity of processes, the dicing machine needs to have the ability to respond quickly and adjust in real time to adapt to different cutting material characteristics and process requirements.

[0014] The embodiment of the present application provides a non-contact height measurement and adjustment method for a dicing machine blade, such as Figure 1 As shown, the method includes:

[0015] Obtain basic cutting information and initial parameters of the height measuring mechanism, wherein the basic cutting information includes cutting material characteristics, cutting requirements and blade parameters, and the initial parameters include mechanism structure parameters and measurement parameters.

[0016] In the embodiment of the present application, the system terminal first obtains the basic cutting information of the dicing machine and the initial parameters of the height measurement mechanism. The basic cutting information includes but is not limited to the cutting material characteristics, cutting requirements and blade parameters. The initial parameters of the height measurement mechanism include but are not limited to the mechanism structure parameters and measurement parameters. Among them, the cutting material characteristics refer to the physical and chemical properties of the material to be cut, such as the hardness, thickness, density and brittleness of the material. These parameters directly affect the requirements for the blade during cutting, as well as the accuracy and method of height measurement adjustment. The cutting requirements involve specific requirements such as cutting depth, cutting width and surface finish, which determine the adjustment range and accuracy required by the blade during the cutting process. The blade parameters include the type, diameter, thickness, material and wear condition of the blade, etc. These parameters need to be comprehensively considered in combination with the characteristics of the cutting material to ensure that the height measurement adjustment during the cutting process can effectively match the actual needs. The mechanism structure parameters refer to the structural characteristics of the height measurement mechanism itself, including the type of measuring device (such as laser ranging device, photoelectric sensor, etc.), measurement range, resolution and installation angle, etc. These parameters determine the basic performance and operability of the height measurement. The measurement parameters are related to the actual height measurement operation, involving the reference height, measurement speed, accuracy requirements, etc., and are the key to ensuring accurate data collection during the height measurement process. The collection of these initial information and parameters is an important basis for ensuring the accuracy of subsequent height measurement adjustments. Through the comprehensive analysis of this information, reliable data support can be provided for the training of the decision-making model and the height measurement adjustment process.

[0017] Based on the basic cutting information and the initial parameters, sample-driven training is performed to determine a height measurement decision model, wherein the height measurement decision model includes a first branch based on laser ranging and a second branch based on photoelectric sensing.

[0018] In one embodiment, the system terminal uses the collected basic cutting information and the initial parameters of the height measurement mechanism to perform sample-driven training according to the first height measurement principle and the second height measurement principle to build an accurate height measurement decision model. The purpose of this decision model is to accurately control the blade height according to different cutting conditions and real-time data to ensure high-precision cutting effects. This height measurement decision model includes a first branch and a second branch. The first branch is determined based on the first height measurement principle and is suitable for cutting scenarios with high precision requirements. The second branch is determined based on the second height measurement principle and is suitable for high-speed or dynamic cutting scenarios. Through sample-driven training, the system terminal can integrate the advantages and disadvantages of the two height measurement methods, laser ranging and photoelectric sensing, and automatically select or combine applicable methods to ensure that the height adjustment during the cutting process is both accurate and efficient. This dual-branch-based height measurement decision model can adapt to different knife speeds and cutting requirements and provide an intelligent height adjustment solution.

[0019] Furthermore, the present application provides the altimetry decision model, comprising:

[0020] Taking the physical characteristics of the light signal as a baseline, the mathematical relationship between the light signal and the blade height is explored to determine the first height measurement principle, wherein the physical characteristics of the light signal at least include the constant speed propagation of the light signal and the negative correlation between the light intensity and the distance; the preset shading ratio is used as the second height measurement principle; based on the first height measurement principle and the second height measurement principle, with the goal of height measurement and adjustment, sample supervised training of the height measurement decision model is carried out.

[0021] Preferably, for laser ranging, the detection of blade height first depends on the physical properties of the light signal. The light signal has a constant propagation speed, and during the propagation process, the light intensity is negatively correlated with the propagation distance. This means that as the distance between the blade and the material surface increases, the light signal intensity received by the photoelectric sensor will gradually weaken. Therefore, using this relationship, the relative height of the blade can be inferred by measuring the change in light intensity. Based on this principle, the system terminal establishes a mathematical relationship between the light signal intensity and the blade height, forming an accurate first height measurement principle for measuring and controlling the blade height. For photoelectric sensing, the height of the blade is determined by detecting the degree of shielding of the emitted light by the blade. When the blade gradually approaches the cutting material, it will shield the light source, causing the light value received by the photoelectric sensor to decrease. In order to accurately measure the height, a preset light shielding ratio (for example, 30% light shielding) is set as the second height measurement principle. This is because when the proportion of the blade shielding the light source reaches the preset value, the light value received by the photoelectric sensor will be reduced to the threshold corresponding to this light shielding ratio. At this time, the blade height at this position is recorded in real time, and it is used as a reference point for height measurement adjustment. In this way, accurate height measurement can be obtained at different knife speeds, which is particularly suitable for real-time detection and control in high-speed cutting scenarios. Based on the above two height measurement principles, the system terminal trains the first branch and the second branch based on the first height measurement principle and the second height measurement principle, respectively, with the goal of height measurement and adjustment.

[0022] For the first height measurement principle, the system terminal encapsulates the established mathematical relationship, constructs the initial first branch, and then inputs the basic cutting information and the actual blade height, laser return time difference, light intensity, knife speed, feed speed, material properties, etc. in the initial parameters into the initial first branch. Through forward propagation, the predicted blade height is calculated layer by layer. Subsequently, the mean square error is used to calculate the direct loss value between the predicted blade height and the actual blade height, and the branch parameters are adjusted through the back propagation algorithm so that the initial first branch can more accurately fit the relationship between the laser ranging data and the actual height. During the training process, the parameters of the first branch and the established mathematical relationship are continuously adjusted to make the relationship between the laser ranging data and the blade height more accurate. After the training is completed, the initial first branch is verified using data that is not used for training, and the actual height of the blade is predicted based on the time difference and intensity changes of the optical signal. If the accuracy of the initial first branch is greater than or equal to the expected expectation, it indicates that the initial first branch training is successful. At this time, the system terminal outputs the initial first branch to obtain the first branch. Otherwise, it is necessary to further optimize the initial first branch, including adjusting the number of samples, the initial first branch parameters, etc.

[0023] For the second height measurement principle, the system terminal constructs the initial second branch based on the neural network, and embeds the preset shading ratio into the initial second branch as a constraint. Subsequently, the basic cutting information and the actual blade height, shading ratio, light intensity data, etc. in the initial parameters are input into the initial second branch. The initial second branch calculates the predicted blade height through forward propagation based on the input shading ratio, light intensity, etc., combined with the preset shading ratio. Then, the above-mentioned loss calculation and back propagation process are performed to gradually adjust the initial second branch until the accuracy of the initial second branch is greater than or equal to the expected expectation, and the second branch is output.

[0024] After the first branch and the second branch are trained separately, the system terminal integrates the two branches to form a complete height measurement decision model. The core of this model is to combine the advantages of laser ranging and photoelectric sensing, and automatically select or merge the two height measurement methods according to different cutting conditions (such as knife speed, feed speed, material properties, etc.) to ensure the accuracy and response speed of blade height prediction, and then adjust the height according to the predicted results, so as to maintain its adaptability in complex cutting scenarios.

[0025] Setting multiple levels of knife speed and configuring a height measurement mode, wherein the height measurement mode includes a dual drive mode based on a first knife speed, a single drive mode based on a second knife speed, and a fast drive mode based on a third knife speed, and the knife speed includes a feed speed and a rotation speed;

[0026] In one embodiment, in order to meet the height measurement requirements under different cutting speeds, the system terminal sets multiple levels of knife speeds, and configures different height measurement modes according to the changes in knife speeds. Specifically, the system terminal divides the knife speed into multiple levels according to the requirements of the cutting task, including but not limited to the first knife speed, the second knife speed, and the third knife speed, and each knife speed includes a feed speed and a rotation speed. The feed speed refers to the speed at which the blade moves forward during the cutting process, which usually determines the cutting efficiency. The rotation speed refers to the rotation speed of the blade, which affects the fineness and quality of the cutting. The setting of the knife speed not only affects the cutting effect, but also determines the selection of the height measurement mode. A lower knife speed is suitable for precise measurement, while a higher knife speed requires a fast-response height measurement mechanism. According to different knife speeds, the system terminal configures three height measurement modes, each of which adapts to different cutting environments and knife speed requirements, including a dual-drive mode based on the first knife speed, a single-drive mode based on the second knife speed, and a fast-drive mode based on the third knife speed. The dual-drive mode based on the first knife speed means that at a lower knife speed, the system terminal enables the dual-drive mode. This mode combines two height measurement methods, laser ranging and photoelectric sensing. Laser distance measurement can provide high-precision distance measurement, while photoelectric sensing is used to monitor the change of blade position in real time. The dual-drive mode ensures that the blade height can be accurately controlled at low knife speeds to meet the requirements of fine cutting. The single-drive mode based on the second knife speed means that when the knife speed increases to the medium range, the system terminal switches to the single-drive mode. In this mode, one of the laser distance measurement or photoelectric sensing is selected for height measurement according to the actual situation. Since the requirements for measurement accuracy for medium-speed cutting are relatively low, a single height measurement method is sufficient to meet the needs, and it can simplify system operation and improve response speed. The fast drive mode based on the third knife speed means that the system terminal enables the fast drive mode when cutting at high speed. This mode relies on photoelectric sensing to monitor the height change of the blade through fast-response light signal detection. Since high-speed cutting requires the system to process a large amount of data in real time, the photoelectric sensor has a faster response capability and can adjust the blade height in time to ensure cutting quality.

[0027] As the dicing machine runs, the real-time knife speed is received and the height measurement mechanism is triggered; if the real-time knife speed is the first knife speed, laser ranging and photoelectric sensor detection are performed, a first height measurement light signal is obtained and transmitted to the controller, triggering the height measurement decision model to perform height measurement calculation and mutual verification, and determine the adjustment data based on the height measurement data.

[0028] In one embodiment, during the operation of the dicing machine, the system terminal continuously monitors and receives the change of the real-time blade speed. When the real-time blade speed is received, the height measurement mechanism is triggered to perform the height measurement operation. When the blade speed is within the first blade speed (usually a lower speed), the system terminal simultaneously enables two detection methods, laser ranging and photoelectric sensor. Laser ranging can provide high-precision distance data, while the photoelectric sensor can monitor the height change of the blade in real time to ensure the reliability of the height measurement data. The height measurement data obtained by these two methods, such as laser reflection signals, light signals of photoelectric sensors, etc., will be recorded in real time, and these recorded data will be transmitted to the controller as input for subsequent calculations. After receiving the height measurement data, the controller will immediately trigger the pre-trained height measurement decision model. The model will pass the input data to the corresponding branches for height calculation to determine whether there is a deviation in the current blade height. At the same time, the results of laser ranging and photoelectric sensing will be mutually verified, that is, the results of laser ranging and photoelectric sensing will be calculated by absolute difference to determine whether the error value of the predicted blade height output by the two branches is within the allowable error range. This allowable error range is set based on business needs to ensure the accuracy and consistency of the height measurement data. When the verification is passed, the system terminal calculates the average of the two predicted blade heights output by the height measurement decision model, and then calculates the difference between the calculated result and the current height of the blade, and uses the calculated height difference as the adjustment data based on the height measurement data. The adjustment data indicates the deviation between the actual position of the blade and the predicted position. A positive value indicates that the blade height is too low and needs to be adjusted upward; a negative value indicates that the blade height is too high and needs to be adjusted downward. Conversely, a relatively more stable data source is selected as a reference based on actual conditions. For example, if the ambient light intensity changes dramatically, laser ranging data is used first; if the laser reflection is unstable during the ranging process, photoelectric sensor data can be used first.

[0029] Further, the present application provides that the real-time knife speed is the second knife speed, including:

[0030] If the real-time knife speed is the second knife speed, the height measuring mechanism is triggered to perform single drive mode height measurement, wherein the single drive mode is laser ranging or photoelectric sensing; the second height measurement light signal is received and transmitted to the controller, triggering the first branch or the second branch, and determining adjustment data based on the height measurement data.

[0031] Preferably, when the dicing machine is running, if the current real-time blade speed is within the second blade speed, the height measurement mechanism will also be automatically triggered to start measuring the height of the blade. In this case, the system terminal will select one of the laser rangefinder or photoelectric sensor to perform the height measurement operation according to the current working environment and needs, and the selection method is the same as when the aforementioned verification fails. Regardless of which height measurement method is selected, the laser rangefinder or photoelectric sensor will generate a second height measurement light signal. This signal contains relevant information about the current height of the blade. The system terminal will receive the signal in real time and transmit it to the controller for subsequent analysis and processing. When the controller receives the height measurement light signal, the system terminal will trigger the corresponding branch in the height measurement decision model to measure the height according to the selected height measurement mode, and generate a predicted blade height. The predicted blade height is then calculated by difference with the current height of the blade to obtain adjustment data based on the height measurement data, thereby ensuring accurate control of the blade height during the cutting process.

[0032] Further, the present application provides that the real-time knife speed is the third knife speed, including:

[0033] If the real-time knife speed is the third knife speed, the photoelectric sensor is triggered to measure the height and the controller is locked; the third height measurement light signal is obtained and transmitted to the driver, the driver latches the height measurement position, checks it with the configured preset height threshold, determines the adjustment data and performs height measurement adjustment drive.

[0034] Optionally, when the dicing machine is running, if the current real-time blade speed is within the third blade speed, the system terminal will trigger the height measurement mechanism and use the photoelectric sensor of the height measurement mechanism to measure the height. This is because the photoelectric sensor has the characteristics of fast response speed during high-speed cutting and can capture the change of blade height in time. While triggering the photoelectric sensor, the system terminal will lock the controller to prevent interference from other signals or data during the height adjustment process, ensuring the stability and continuity of the height measurement operation. The photoelectric sensor determines the height of the blade by monitoring the change of the light signal. This process generates a third height measurement light signal, which contains information such as the current actual height of the blade. The system terminal will immediately transmit the third height measurement light signal to the driver for subsequent height adjustment. When the driver receives the third height measurement light signal, it will measure the height based on the second branch in the high decision model, obtain the predicted blade height and latch it as the height measurement position. Subsequently, the driver will compare and calibrate the predicted blade height with the preset height threshold. This preset threshold is the target height set according to the requirements of the cutting task, and the system terminal will use this threshold to determine whether the predicted blade height is within the allowable range. If the predicted blade height is within the preset height threshold, the system terminal calculates the difference between the preset height threshold and the current blade height as adjustment data, and then executes the height measurement adjustment drive based on this adjustment data, that is, the blade height is adjusted in real time to ensure that the blade height is consistent with the predicted height, thereby ensuring cutting accuracy. On the contrary, if the predicted blade height exceeds the preset height threshold range, it indicates that there is a large deviation between the predicted result and the actual situation at this time, and the system terminal marks the predicted result as abnormal. At this time, re-measurement will be automatically triggered, no longer relying on the current predicted data, but on the latest photoelectric sensor data for height measurement.

[0035] Further, the present application provides a first knife speed, a second knife speed, and a third knife speed, including:

[0036] The first knife speed is less than the second knife speed and less than the third knife speed, and the first knife speed, the second knife speed and the third knife speed are interval knife speeds.

[0037] Optionally, the system terminal divides the rotation speed and feed speed of the blade into different intervals according to the requirements of the actual cutting task, and manages them in order from low to high, including but not limited to the first blade speed, the second blade speed, and the third blade speed. These blade speed intervals represent different working conditions and cutting requirements, respectively, to ensure that the most suitable height measurement mode and adjustment method can be automatically selected at different blade speeds. Among them, the first blade speed belongs to the lowest blade speed interval, which is usually used for fine and slow cutting operations. The second blade speed is in the medium blade speed interval and is suitable for general cutting tasks. The third blade speed is the highest blade speed interval, which is suitable for fast cutting or efficient mass production.

[0038] Further, the present application provides signal compensation, including:

[0039] Acquire the operation scenario of the dicing machine and determine the environmental influencing factors; traverse the environmental influencing factors and mine the optical signal distortion function based on the environmental influencing factors, wherein the optical signal distortion function includes a single factor function and a multi-factor collaborative function; based on the optical signal distortion function, supervise the training of the environmental compensation branch; introduce the environmental compensation branch to perform signal compensation on the first, second and third received height measurement optical signals.

[0040] Optionally, in order to ensure the high measurement accuracy, the system terminal compensates for the interference of external environmental factors on the optical signal. First, according to the operation scenario of the dicing machine, identify and obtain the influencing factors related to the current environment. These factors include but are not limited to temperature, air refractive index, vibration, and ambient light. These environmental factors have a great impact on the propagation and measurement accuracy of the optical signal during the cutting process, so compensation is required for each environmental factor. After identifying the environmental influencing factors, these factors will be traversed one by one to analyze the degree of their influence on the optical signal. In order to quantify this influence, the system terminal constructs an optical signal distortion function, which includes a single factor function and a multi-factor collaborative function. The single factor function is for each single environmental factor, such as temperature, vibration, etc. The multi-factor collaborative function is for the distortion of the optical signal when multiple environmental factors act simultaneously. Subsequently, the optical signal distortion function is integrated based on the neural network to construct the initial environmental compensation branch, and then the environmental factor sample data and the actual optical signal measurement results are used to obtain the environmental compensation branch through the same supervised training process as mentioned above. After the environmental compensation branch training is completed, the system terminal introduces the environmental compensation branch into the height measurement process, and corrects the error in the optical signal caused by external factors by inputting the first height measurement optical signal, the second height measurement optical signal and the third height measurement optical signal into the environmental compensation branch. The compensated optical signal will be more accurate, ensuring that the system terminal can still obtain stable and accurate blade height data in various complex environments.

[0041] The controller outputs a driving signal based on the adjustment data and transmits it to the driver to perform height measurement adjustment control.

[0042] In one embodiment, after the controller obtains the adjustment data, the controller converts the adjustment data into a drive signal. The drive signal is transmitted to the actuator, i.e., the driver, through the control network to instruct the driver to perform a specific adjustment action. The drive signal usually contains a precise set of instructions, including key information such as the height and direction to be adjusted. After the driver receives the drive signal from the controller, it will perform corresponding actions according to the instructions in the drive signal, and adjust the height of the blade by controlling the mechanical structure (such as a servo motor) so that the position of the blade accurately reaches the target height set by the controller, thereby ensuring accuracy and efficiency during the cutting process.

[0043] Furthermore, the present application provides for performing height measurement update management, including:

[0044] Receive processing condition variables; introduce a programmable module, traverse the processing condition variables, and determine an update logic program, wherein the programmable module is electrically connected to a dicing machine; and perform height measurement update management based on the update logic program.

[0045] Preferably, the system terminal first receives processing condition variables in real time, including but not limited to changes in cutting materials, changes in height limit standards, and changes in cutting modes. For cutting materials, the surface properties of different materials (such as reflectivity, roughness, etc.) will affect the reflection of the light signal, thereby affecting the height measurement accuracy. For the height limit standard, the height limit standard (such as the maximum or minimum height of the blade) may need to be adjusted due to different processing tasks. For the cutting mode, the requirements for the cutting mode (such as high-speed cutting, fine cutting, etc.) may be different due to different processing tasks. Subsequently, the system terminal introduced a programmable module and electrically connected it to the dicing machine, that is, the programmable module is connected to the main control system of the dicing machine through electrical signals to ensure that the operating state of the dicing machine can be directly controlled and adjusted. In the programmable module, the system terminal checks the received variables one by one, such as material surface reflectivity, cutting speed, height limit, etc., to determine whether the height measurement method needs to be adjusted. Based on the traversal results, an update logic program suitable for the current processing conditions is generated. For example, if it is detected that the reflectivity of the material is reduced, resulting in a decrease in the accuracy of the laser ranging, it is necessary to switch from the laser ranging mode to the photoelectric sensor mode to ensure that a high degree of measurement accuracy can be maintained under the new material conditions. When the reflectivity of the material changes significantly, the height limit needs to be adjusted accordingly so that the maximum or minimum height range of the blade is more suitable for the characteristics of the current material, ensuring that the processing quality is not affected or the blade is damaged due to improper limit during cutting. Afterwards, according to the update logic program generated by the programmable module, the system terminal performs the corresponding height measurement update management, including switching of the height measurement mode, changes in the maximum or minimum height, etc., to ensure stable operation under complex working conditions.
