[0006] Through this solution, the pickup head information and chip information of the electromagnetic device are obtained, the adsorption status of the chip to be transferred is grasped in real time, and the real-time adsorption information of the chip to be transferred is determined based on this. By obtaining the real-time transfer image and transfer equipment information during the transfer process, combined with the real-time adsorption information, the motion trajectory and current state of the chip to be transferred are accurately determined to form real-time motion information. The target substrate information is obtained, and the real-time motion information is integrated to formulate a real-time adjustment plan during the transfer process of the chip to be transferred. According to the real-time adjustment plan, the transfer process of the chip to be transferred is adjusted in real time to avoid production errors caused by unstable adsorption or motion deviation, thereby ensuring that the chip to be transferred is accurately and smoothly transferred to the target substrate. Effectively improve production accuracy and efficiency, reduce operational errors, and ensure high-quality display panel manufacturing.

[0008] Through this solution, the surface roughness of the pickup head and the contact area between the chip to be transferred and the pickup head are analyzed through the pickup monitoring image. This helps to accurately calculate the adsorption strength of the chip to be transferred on the pickup head. The real-time adsorption strength is calculated by applying the formula based on the surface roughness, standard contact area, real-time contact area, chip weight and real-time current. The real-time adsorption strength is incorporated into the real-time adsorption information to accurately monitor and adjust the adsorption state of the pickup process, thereby improving the stability and accuracy of the chip to be transferred, and ensuring the safety and transfer efficiency of the chip to be transferred.

[0010] Through this solution, the surface roughness of the chip is analyzed through real-time transfer images, and the required arrival time is determined based on the motion trajectory of the chip to be transferred from release to the current position. Combined with the real-time motion temperature, arrival time, surface roughness, real-time current, chip weight and real-time adsorption strength, the formula is applied to calculate the real-time motion speed of the chip to be transferred during the motion process. The friction coefficient, the influence of temperature on friction, the correlation between current and adsorption force and other factors are comprehensively considered to accurately reflect the speed change of the chip to be transferred during the motion process. By introducing parameters such as preset friction coefficient, temperature friction coefficient, rough friction coefficient and current adsorption coefficient, the comprehensiveness and accuracy of the calculation are ensured. After the real-time motion speed is calculated, this information will be used as part of the real-time motion information to monitor the motion state of the chip to be transferred in real time, provide accurate data support for subsequent operations, optimize adsorption and stability control during the motion process, and improve the efficiency and reliability of the transfer of the chip to be transferred.

[0012] Through this scheme, the actual landing point of the chip to be transferred on the target substrate is predicted by real-time movement speed, real-time adsorption strength and chip weight, ensuring a preliminary estimate of the target landing point. The actual landing point is compared with the ideal landing point, the landing point distance between the two is calculated, and the corresponding error range is determined. If the actual landing point exceeds the error range, adjustment is required. According to the actual landing point, distance error and chip weight, the required magnetic field adjustment strength is calculated to correct the landing point deviation of the chip to be transferred. The real-time adjustment strength is incorporated into the real-time adjustment scheme to ensure that the chip to be transferred can accurately fall in the ideal position. By accurately predicting and dynamically adjusting the magnetic field strength, the position error in the transfer of the chip to be transferred is effectively reduced, and the accuracy and stability of the transfer process are improved.

[0014] Through this scheme, the angle between the speed and the magnetic field is determined according to the initial release speed and magnetic field direction of the chip to be transferred. The equivalent charge is calculated by combining the magnetic field strength, the speed magnetic field angle and the initial release speed. By considering factors such as chip weight, adsorption angle, magnetic field strength, initial release speed, equivalent charge, speed magnetic field angle, etc., the formula is used to calculate the real-time motion angle of the chip to be transferred during the movement. It reflects the changes in the motion state of the chip to be transferred under the action of the external magnetic field. According to the deviation between the ideal motion angle and the actual motion angle, the angle deviation value is calculated. If a deviation exists, the magnetic field direction will be adjusted to determine the required direction adjustment angle and incorporate it into the real-time adjustment plan. Through this dynamic adjustment, it is ensured that the chip to be transferred can maintain the ideal motion trajectory during the transfer process, thereby improving the motion accuracy and stability of the chip to be transferred and optimizing the control during the transfer process.

[0016] Through this scheme, the spacing distance between the chip to be transferred and the target substrate is determined by the real-time transfer image. Combined with the real-time movement speed, spacing distance, magnetic permeability of the target substrate, magnetic permeability of the chip, initial release speed, real-time adsorption strength and chip weight, the magnetic field attenuation speed adjustment value of the chip to be transferred during the release process is calculated. By introducing the preset speed coefficient and attenuation constant, the speed of the magnetic field attenuation during the release process of the chip to be transferred is accurately reflected, and data support is provided for subsequent adjustments. The obtained speed adjustment value will be incorporated into the real-time adjustment scheme to ensure that the magnetic field attenuation of the chip to be transferred during the transfer process is effectively controlled, thereby optimizing the release process of the chip to be transferred and improving the accuracy and stability of the transfer.

If there are contaminants, the image is further analyzed to determine the actual number of chips and the type of contaminants on the target substrate. According to the type of contaminant and the real-time surface temperature, the degree of adhesion of the contaminant on the substrate is evaluated. Taking into account the actual degree of adhesion, chip weight, real-time surface temperature, substrate roughness and the actual number of chips, the appropriate ultrasonic cleaning frequency is calculated to ensure the best cleaning effect. The combined effect of the preset cleaning coefficient, actual degree of adhesion, chip weight, substrate roughness, real-time surface temperature and number of chips ensures that the cleaning effect is as expected under different cleaning conditions. By adjusting the ultrasonic cleaning frequency in real time, the contaminants on the target substrate can be effectively removed, ensuring the smooth transfer process of the chips to be transferred and improving the transfer accuracy and efficiency.

It reflects the degree of deviation of the chip to be transferred from the ideal target position during the transfer process. According to the size and shape of each chip to be transferred, the rotation priority of the target substrate is determined, that is, which chips to be transferred need to be rotated more preferentially to reduce the deviation. According to the deviation angle and rotation priority, the angular rotation order of the target substrate is determined, so as to adjust the angle of the substrate in an orderly manner to ensure that the chip to be transferred can fall in the ideal position as accurately as possible. Through this dynamic adjustment scheme, the transfer process of the chip to be transferred can be precisely controlled, thereby effectively reducing the position deviation of the chip to be transferred and improving the accuracy and efficiency of the transfer.

The surface roughness, standard contact area, contact area, chip weight, real-time current, preset adjustment constant and preset current enhancement coefficient are analyzed by a mathematical analysis method, and the real-time adsorption strength of the chip to be transferred on the pickup head is determined according to formula (1).
[0059] In formula (1), the contact area The larger the value, the stronger the contact force between the chip to be transferred and the pickup head. Standard contact area Used to compare actual contact area. Rough surfaces provide more tiny contact points, thus increasing adhesion. Considering them together is equivalent to adding a practical correction to the contact strength into the formula. When the contact area increases, the adsorption force should also increase accordingly; and the increase in surface roughness will increase the contact force. This is reflected in the formula. By correcting the actual contact area and roughness, the calculation results can be made more consistent with the actual situation. The larger it is, the stronger the contact force and the greater the adsorption force. The influence of surface microstructure is considered. The larger it is, the greater the contact force will generally be, as it directly affects the strength of the adsorption force.

It directly determines the gravity that the adsorption force needs to overcome. ,Formula (1) can adapt to the situation of chips with different weights to be transferred, ensuring the accurate calculation of the adsorption force.
[0061] :The pickup head uses the electromagnetic principle to enhance the adsorption force. The larger the current, the stronger the electromagnetic effect, which in turn enhances the adsorption force. The change of real-time current will affect the strength of the electric field, which directly affects the adsorption strength. By introducing the current enhancement factor , the adsorption force can be dynamically adjusted to cope with the working conditions under different currents, ensuring the stability of the picking process.

[0070] The preset current absorption coefficient may be a value indicating the influence of the real-time current on the calculation result of the real-time movement speed when calculating the real-time movement speed.
[0071] Specifically, the real-time transfer image is analyzed using an image analysis method to obtain the chip surface roughness. The real-time transfer image is analyzed using a target detection and tracking algorithm to obtain the arrival time required for the chip to be transferred to reach the current position after the release begins. The historical real-time motion temperature, historical arrival time, historical chip surface roughness, historical real-time current, historical chip weight and historical real-time adsorption strength are obtained from the production and manufacturing system, and the historical real-time motion temperature, historical arrival time, historical chip surface roughness, historical real-time current, historical chip weight and historical real-time adsorption strength are analyzed using a linear regression analysis method to obtain a preset friction coefficient, a preset temperature friction coefficient, a preset rough friction coefficient and a preset current adsorption coefficient.

The real-time motion speed of the chip to be transferred during the motion process is obtained according to formula (2), and the real-time motion speed is incorporated into the real-time motion information.
[0072] In formula (2), the effect of temperature on friction is expressed by and real-time motion temperature As the temperature increases, the friction of an object tends to change, which can be modeled by the temperature friction coefficient As the temperature increases, the friction coefficient decreases, which means that the movement of the chip to be transferred becomes smoother. This adjustment is based on the effect of temperature on the material properties. Too high or too low a temperature will change the nature of the friction. Affects the friction between the contacting surfaces. A rougher surface generally increases friction, thus slowing down the movement of the chip being transferred. The effect of friction on to adjust, reflecting the difference in friction between rough and smooth surfaces.
[0073] Real-time adsorption strength Generated by the interaction between the electromagnetic field and the chip to be transferred. Real-time current It will affect the strength of the adsorption force, because the electromagnetic adsorption force is proportional to the current. Therefore, the greater the real-time current, The stronger it is, the slower the movement of the chip to be transferred may be. Real-time current The influence of a preset current absorption coefficient Make adjustments. This affects the effect of gravity, which in turn affects the amount of friction. Heavier chips to be transferred will produce greater friction, so more suction force is required to overcome friction.
[0074] Real-time motion temperature Impact on movement: During the electromagnetic transfer process, the temperature of the chip to be transferred is not only affected by the external environment, but also changes due to factors such as friction and current. It is mainly reflected in the following aspects: 1. The friction coefficient of the material will decrease or increase with the increase of temperature, which directly affects the movement of the chip. As the temperature rises, the friction force will decrease, resulting in smoother movement of the chip to be transferred. 2. If the temperature of the chip to be transferred is too high, it will cause material deformation, thermal expansion or changes in electromagnetic properties, which will affect the movement trajectory. 3. Temperature will affect the electromagnetic adsorption force. When the current passes through the electromagnetic field, the temperature change will cause the adsorption force to change, thereby affecting the movement speed of the chip to be transferred. The effect of temperature on the coefficient of friction is described. Controls the effect of temperature changes on friction. When the temperature rises, Increase, The temperature will decrease, thus reducing the influence of friction and making the chip to be transferred move faster. Temperature changes can have a positive or negative effect on friction.

Combined with the real-time motion temperature, arrival time, surface roughness, real-time current, chip weight and real-time adsorption strength, the formula is applied to calculate the real-time motion speed of the chip to be transferred during the motion process. The friction coefficient, the influence of temperature on friction, the correlation between current and adsorption force and other factors are comprehensively considered to accurately reflect the speed change of the chip to be transferred during the motion process. By introducing parameters such as preset friction coefficient, temperature friction coefficient, rough friction coefficient and current adsorption coefficient, the comprehensiveness and accuracy of the calculation are ensured. After the real-time motion speed is calculated, this information will be used as part of the real-time motion information to monitor the motion state of the chip to be transferred in real time, provide accurate data support for subsequent operations, optimize adsorption and stability control during the motion process, and improve the efficiency and reliability of the transfer of the chip to be transferred.

[0080] The real-time adjustment strength may be an adjustment value determined when the magnetic field strength of the pickup head is adjusted in real time after the chip to be transferred is released from the pickup head and moves.
[0081] Specifically, a mathematical analysis method is used to analyze the real-time motion speed, real-time adsorption strength and chip weight to predict the actual landing position of the chip to be transferred on the target substrate. The ideal landing position of the chip to be transferred on the target substrate is extracted from the target substrate information. A spatial rectangular coordinate system is established with the actual landing position as the coordinate origin, and the ideal landing position is marked in the spatial rectangular coordinate system to obtain the coordinates of the ideal landing position. The ideal landing position coordinates and the coordinate origin are analyzed using a mathematical analysis method to obtain the landing position distance. The position distance error range is obtained from the production and manufacturing system, and the landing position distance is matched with the position distance error range to determine whether the landing position distance is within the position distance error range. If not, the maximum distance error is extracted from the position distance error range. The maximum distance error is subtracted from the landing position distance to obtain a distance subtraction value. Based on the actual landing position, a mathematical analysis method is used to analyze the distance subtraction value and the chip weight to obtain a real-time adjustment strength, and the real-time adjustment strength is incorporated into the real-time adjustment plan.
[0082] Through this scheme, the actual landing point of the chip to be transferred on the target substrate is predicted by real-time movement speed, real-time adsorption strength and chip weight, ensuring a preliminary estimate of the target landing point. The actual landing point is compared with the ideal landing point, the landing point distance between the two is calculated, and the corresponding error range is determined. If the actual landing point exceeds the error range, adjustment is required. According to the actual landing point, distance error and chip weight, the required magnetic field adjustment strength is calculated to correct the landing point deviation of the chip to be transferred. The real-time adjustment strength is incorporated into the real-time adjustment scheme to ensure that the chip to be transferred can accurately fall in the ideal position. By accurately predicting and dynamically adjusting the magnetic field strength, the position error in the transfer of the chip to be transferred is effectively reduced, and the accuracy and stability of the transfer process are improved.

[0090] The angle deviation value may be a value obtained by subtracting the ideal motion angle from the real-time motion angle.
[0091] The direction adjustment angle may be a value determined when the angle corresponding to the magnetic field direction of the pickup head is adjusted when the chip to be transferred moves after being separated from the pickup head.
[0092] Specifically, the magnetic field strength and magnetic field direction of the pickup head are extracted from the pickup head information. The adsorption angle is extracted from the real-time adsorption information. The initial release speed is extracted from the real-time motion information. The initial release direction is extracted from the initial release speed, and the initial release direction and the magnetic field direction are marked in the spatial rectangular coordinate system obtained in the above steps to obtain the initial release direction coordinates and the magnetic field direction coordinates. The initial release coordinates and the magnetic field direction coordinates are analyzed using a mathematical analysis method to obtain the speed magnetic field angle. The magnetic field strength, speed magnetic field angle and initial release speed are analyzed using a mathematical analysis method to obtain the equivalent charge. The chip weight, adsorption angle, magnetic field strength, initial release speed, equivalent charge, speed magnetic field angle, magnetic field direction and real-time adsorption strength are analyzed using a mathematical analysis method, and the real-time motion angle is calculated according to formula (3).
[0093] In formula (3), Describes the component of the resultant force that affects the movement angle of the chip to be transferred in the vertical direction (assuming it is the movement direction of the chip): It is the component of the adsorption force in the direction of chip movement, which provides a certain force support. Acting on the chip to be transferred in the vertical direction, a downward force is generated. It is caused by the effect of the magnetic field on the transfer chip. Indicates the magnitude of the force applied to the chip to be transferred in the magnetic field after it is charged. is the adjustment coefficient of the magnetic field force, which represents the component of the magnetic field force in the vertical direction. It represents the resultant force of all forces in the vertical direction (the component in the direction of chip movement), which determines whether the movement of the chip to be transferred is affected by gravity, and how the adsorption force and magnetic field force work together.
[0094] Describes the component of the resultant force that affects the chip's motion angle in the horizontal direction (perpendicular to the chip's motion direction): The effect of magnetic field on the chip to be transferred. Compared with the previous item, Considering the horizontal component of the magnetic field force, It is to adjust the coefficient of this force in the horizontal direction. When the chip to be transferred moves in the magnetic field, the magnetic field force not only has an effect in the vertical direction, but also has a certain effect in the horizontal direction. It comes from the horizontal component of the adsorption force, which determines the adsorption force effect on the chip to be transferred during the release process. It represents the component of the resultant force in the horizontal direction, and describes the combined effect of the magnetic field force and the adsorption force in the horizontal direction on the chip to be transferred when it moves.
[0095] The ideal motion angle is obtained from the manufacturing system, and the ideal motion angle is subtracted from the real-time motion angle to obtain the angle deviation value. The angle deviation value, real-time adjustment strength and magnetic field direction are analyzed using mathematical analysis methods to obtain the direction adjustment angle, which is then incorporated into the real-time adjustment plan.
[0096] Through this scheme, the angle between the speed and the magnetic field is determined according to the initial release speed and magnetic field direction of the chip to be transferred. The equivalent charge is calculated by combining the magnetic field strength, the speed magnetic field angle and the initial release speed. By considering factors such as chip weight, adsorption angle, magnetic field strength, initial release speed, equivalent charge, speed magnetic field angle, etc., the formula is used to calculate the real-time motion angle of the chip to be transferred during the movement. It reflects the changes in the motion state of the chip to be transferred under the action of the external magnetic field. According to the deviation between the ideal motion angle and the actual motion angle, the angle deviation value is calculated. If a deviation exists, the magnetic field direction will be adjusted to determine the required direction adjustment angle and incorporate it into the real-time adjustment plan. Through this dynamic adjustment, it is ensured that the chip to be transferred can maintain the ideal motion trajectory during the transfer process, thereby improving the motion accuracy and stability of the chip to be transferred and optimizing the control during the transfer process.
[0097] In some embodiments, the spacing distance between the chip to be transferred and the target substrate is determined according to the real-time transfer image; the speed adjustment value of the magnetic field attenuation speed of the chip to be transferred during the release process is determined according to the real-time movement speed, the spacing distance, the magnetic permeability of the target substrate, the initial release speed, the magnetic permeability of the chip, the real-time adsorption strength and the chip weight, and the speed adjustment value is incorporated into the real-time adjustment scheme: (4) in, Indicates the speed adjustment value.

[0099] The magnetic permeability of the target substrate may be a value corresponding to a physical quantity of the target substrate's ability to conduct magnetic flux.
[0100] The chip magnetic permeability may be a physical quantity value of the ability of the chip to be transferred to conduct magnetic flux.
[0101] The speed adjustment value may be an adjustment value determined by adjusting the attenuation speed corresponding to the magnetic field generated by the pickup head in order to make the chip fall accurately on the ideal position of the target substrate after the chip to be transferred leaves the pickup head and starts to move.
[0102] The preset speed coefficient may be a value indicating the comprehensive influence of each calculation factor on the calculation result of the speed adjustment value when calculating the speed adjustment value.
[0103] The preset distance attenuation constant may be a value indicating the effect of the interval distance on the calculation result of the speed adjustment value when calculating the speed adjustment value.
[0104] Specifically, computer vision processing technology is used to analyze the real-time transfer image to obtain the interval distance between the chip to be transferred and the target substrate. The historical real-time movement speed, historical interval distance, historical target substrate magnetic permeability, historical initial release speed, historical chip magnetic permeability, historical real-time adsorption strength and historical chip weight are obtained from the production and manufacturing system, and the historical real-time movement speed, historical interval distance, historical target substrate magnetic permeability, historical initial release speed, historical chip magnetic permeability, historical real-time adsorption strength and historical chip weight are analyzed using a linear regression analysis method to obtain a preset speed coefficient and a preset distance attenuation constant. The target substrate magnetic permeability is extracted from the target substrate information. The chip magnetic permeability is extracted from the chip information. The real-time movement speed, interval distance, target substrate magnetic permeability, initial release speed, chip magnetic permeability, real-time adsorption strength, chip weight, preset speed coefficient and preset distance attenuation constant are analyzed using a mathematical analysis method to obtain the speed adjustment peak value of the magnetic field attenuation speed of the chip to be transferred during the release process, and the speed adjustment peak value is incorporated into the real-time adjustment scheme.
[0105] Among them, in formula (4), the numerator is: middle, and Determines the material's ability to respond to magnetic fields. and The larger it is, the more attractive the chip to be transferred will be. The magnetic interaction between the chip to be transferred and the target substrate can be quantified. If the magnetic permeability of the chip to be transferred or the target substrate is higher, the chip to be transferred will be subjected to a stronger magnetic field, requiring a larger speed adjustment (i.e., increasing the magnetic field). ). Assume that the speed of the chip to be transferred when it starts to be released is , the speed of the chip to be transferred will change as the magnetic field force between the chip to be transferred and the target substrate acts. As time goes by, the real-time motion speed It will slow down or speed up due to the change of magnetic field attraction. The larger it is, the more the speed of the chip to be transferred deviates from the initial setting value, and more speed adjustments are needed to correct its motion trajectory. Directly affects the speed adjustment value, which reflects the difference between the actual movement speed of the chip to be transferred and the initial release speed. The larger it is, the greater the degree of adjustment.
[0106] Denominator: The strength of the magnetic field usually decreases with increasing distance, so the separation distance In the denominator, it plays a role in weakening the magnetic field force. The farther the distance between the chip to be transferred and the target substrate, the weaker the magnetic field force will be, and a stronger speed adjustment is required to maintain the motion trajectory of the chip to be transferred. In the process, gravity causes the chip to be transferred to always be subjected to a downward force. This force and Closely related. Usually, The larger the adsorption force, the greater the inertia that the magnetic field force needs to overcome, making speed adjustment more difficult. Under the magnetic force between the chip to be transferred and the target substrate, the stronger the adsorption force, the greater the magnetic field force on the chip, and the speed of movement will also change. If the adsorption force is very strong, the acceleration of the chip to be transferred will be greater, and the speed change will be faster, so more precise adjustments are required. Putting it in the denominator reflects its inhibitory effect on speed adjustment: the greater the force on the chip to be transferred, the more difficult it is to change the speed, so a smaller speed adjustment is required. The reason for the denominator is that the farther the distance, the weaker the magnetic field strength, so a smaller speed adjustment value is needed to adjust the chip speed to adapt to the distance attenuation effect. The position of the denominator shows that a larger force will slow down the change in speed, so a relatively small speed adjustment value is needed to adjust the movement of the chip to be transferred.
[0107] Through this scheme, the spacing distance between the chip to be transferred and the target substrate is determined by the real-time transfer image. Combined with the real-time movement speed, spacing distance, magnetic permeability of the target substrate, magnetic permeability of the chip, initial release speed, real-time adsorption strength and chip weight, the magnetic field attenuation speed adjustment value of the chip to be transferred during the release process is calculated. By introducing the preset speed coefficient and attenuation constant, the speed of the magnetic field attenuation during the release process of the chip to be transferred is accurately reflected, and data support is provided for subsequent adjustments. The obtained speed adjustment value will be incorporated into the real-time adjustment scheme to ensure that the magnetic field attenuation of the chip to be transferred during the transfer process is effectively controlled, thereby optimizing the release process of the chip to be transferred and improving the accuracy and stability of the transfer.
[0108] In some embodiments, it is determined whether there are contaminants on the target substrate according to the real-time transfer image; if there are contaminants, the actual number of chips on the target substrate and the type of contaminants are determined according to the real-time transfer image; the actual degree of adhesion of the contaminants on the target substrate is determined according to the type of contaminants and the real-time surface temperature; the acoustic wave cleaning frequency is determined according to the actual degree of adhesion, chip weight, real-time surface temperature, substrate roughness and actual number of chips, and the acoustic wave cleaning frequency is determined according to formula (5): (5) in, Indicates the frequency of sonic cleaning, Indicates the preset cleaning coefficient, Indicates the actual degree of adhesion.

[0109] The real-time surface temperature may be the temperature of the target substrate surface when the chip to be transferred is separated from the pickup head and starts to move.
[0110] The actual adhesion degree may be a numerical value corresponding to the degree to which the contaminant is adhered or fixed on the target substrate when the contaminant is on the target substrate.
[0111] The acoustic wave cleaning frequency may be the number of times the acoustic wave vibrates per second when the acoustic wave is used to clean the contaminants when the contaminants are present on the target substrate.
[0112] The preset cleaning coefficient may be a value indicating the comprehensive influence of each calculation factor on the calculation result of the ultrasonic cleaning frequency when calculating the ultrasonic cleaning frequency.
[0113] Specifically, a feature recognition algorithm is used to analyze the real-time transfer image to determine whether there are contaminants on the target substrate. If there are contaminants, the feature recognition algorithm is used to analyze the real-time transfer image to obtain the actual number of chips on the target substrate, the volume of contaminants and the type of contaminants. The real-time surface temperature is extracted from the target substrate information. All possible types of contaminants and their corresponding densities are obtained from the production and manufacturing system, and all possible types of contaminants and their corresponding densities are integrated to obtain a preset type density set. The contaminant type is matched with the preset type density set to obtain the density corresponding to the contaminant type, and the density corresponding to the contaminant type is determined as the contaminant density. The real-time surface temperature, contaminant density and contaminant volume are analyzed using a mathematical analysis method to obtain the actual degree of attachment. The historical actual degree of attachment, historical chip weight, historical real-time surface temperature, historical substrate roughness and historical actual number of chips are obtained from the production and manufacturing system, and the historical actual degree of attachment, historical chip weight, historical real-time surface temperature, historical substrate roughness and historical actual number of chips are analyzed using a linear regression analysis method to obtain a preset cleaning coefficient. The preset cleaning coefficient, actual adhesion degree, chip weight, real-time surface temperature, substrate roughness and actual number of chips are analyzed using mathematical analysis methods, and the acoustic cleaning frequency is calculated according to formula (5).
[0114] Among them, in formula (5), the numerator is: Indicates the actual adhesion degree of contaminants and the inertia of the chip, It determines the physical force that needs to be overcome when the contaminants are cleaned. The greater the degree of real-time adhesion and the heavier the chip, the higher the frequency of ultrasonic cleaning is required to effectively remove the contaminants.
[0115] Denominator: middle, The higher the value, the weaker the actual adhesion of the contaminants, in which case the cleaning frequency will be reduced accordingly. The higher the value, the lower the cleaning frequency required. This parameter helps adjust the effect of temperature on cleaning results. In the process, the higher the roughness of the target substrate, the more difficult it is to clean, which means that a higher acoustic wave frequency is required. Therefore, the roughness of the target substrate has an inverse effect on the demand for acoustic wave frequency. The higher the roughness, the more energy is required to ensure cleaning efficiency. Multiple chips to be transferred means that the acoustic wave energy needs to be dispersed. A lower frequency is required when cleaning each chip to be transferred to avoid over-cleaning of a chip to be transferred, because multiple chips to be transferred increase the distribution requirements of the acoustic wave energy. Therefore, in practical applications, the more chips to be transferred, the lower the cleaning frequency will be.
[0116] Through this solution, the real-time transfer image is used to determine whether there are contaminants on the target substrate. If there are contaminants, the image is further analyzed to determine the actual number of chips and the type of contaminants on the target substrate. According to the type of contaminant and the real-time surface temperature, the degree of adhesion of the contaminant on the substrate is evaluated. Taking into account the actual degree of adhesion, chip weight, real-time surface temperature, substrate roughness and the actual number of chips, the appropriate ultrasonic cleaning frequency is calculated to ensure the best cleaning effect. The combined effect of the preset cleaning coefficient, actual degree of adhesion, chip weight, substrate roughness, real-time surface temperature and number of chips ensures that the cleaning effect is as expected under different cleaning conditions. By adjusting the ultrasonic cleaning frequency in real time, the contaminants on the target substrate can be effectively removed, ensuring the smooth transfer process of the chips to be transferred and improving the transfer accuracy and efficiency.
[0117] In some embodiments, based on the real-time transfer image, the real-time position of each chip to be transferred when it reaches the top of the target substrate is determined; the ideal landing position and the real-time position are matched to determine the deviation angle of each chip to be transferred between the real-time position and the ideal landing position; based on the chip size and chip shape, the rotation priority of the target substrate is determined; based on the deviation angle and the rotation priority, the angular rotation order of the target substrate is determined, and the angular rotation order is incorporated into the real-time adjustment plan.

[0120] The rotation priority may be a rotation priority order of each type of chip corresponding to the target substrate when the target substrate is rotated.
[0121] The angular rotation order may be an arrangement order of each rotation angle of the target substrate when it is rotated.
[0122] Specifically, a computer vision algorithm is used to analyze the real-time transfer image to obtain the real-time position of each chip to be transferred when it reaches the top of the target substrate, and the real-time position is marked in the spatial rectangular coordinate system obtained in the above steps to obtain the real-time position coordinates. The ideal landing point position coordinates and the real-time position coordinates are analyzed using a mathematical analysis method to obtain the deviation angle. The chip size and chip shape of each chip to be transferred are extracted from the chip information. Based on the chip shape, the length and width of each chip to be transferred are extracted from the chip size. The length and width of each chip to be transferred are divided to obtain a number of aspect ratios, and the several aspect ratios are arranged in order from large to small to obtain the size arrangement order of the aspect ratios, and the size order of the aspect ratios is determined as the rotation priority of the target substrate. The deviation angles of each chip to be transferred obtained in the above steps are arranged in order from large to small to obtain the deviation angle order. The deviation angle order corresponding to the rotation priority is determined as the angle rotation order, and the angle rotation order is included in the real-time adjustment plan.
[0123] Through this scheme, the real-time position of each chip to be transferred when it reaches the top of the target substrate is determined by real-time transfer images. The real-time position of each chip to be transferred is matched with the ideal landing point position, so as to calculate the deviation angle of each chip to be transferred. It reflects the degree of deviation of the chip to be transferred from the ideal target position during the transfer process. According to the size and shape of each chip to be transferred, the rotation priority of the target substrate is determined, that is, which chips to be transferred need to be rotated more preferentially to reduce the deviation. According to the deviation angle and rotation priority, the angular rotation order of the target substrate is determined, so as to adjust the angle of the substrate in an orderly manner to ensure that the chip to be transferred can fall in the ideal position as accurately as possible. Through this dynamic adjustment scheme, the transfer process of the chip to be transferred can be precisely controlled, thereby effectively reducing the position deviation of the chip to be transferred and improving the accuracy and efficiency of the transfer.
[0124] In some embodiments, the movement trajectory of the chip to be transferred after the release is predicted based on the initial release speed, chip weight, real-time adsorption strength and magnetic field direction; the actual movement trajectory of the chip to be transferred after the release is determined based on the real-time movement direction and real-time movement speed; the movement trajectory is matched with the actual movement trajectory, and if the movement trajectory is inconsistent with the actual movement trajectory, the secondary movement direction and secondary movement speed corresponding to the secondary movement of the chip to be transferred after the release are determined based on the real-time transfer image; the airflow information is obtained, and the airflow velocity and airflow intensity are determined based on the airflow information; the secondary movement trajectory corresponding to each chip to be transferred is determined based on the secondary movement direction, airflow velocity, airflow intensity, chip weight and secondary movement speed; the gradient adjustment value of the magnetic field is determined based on the secondary movement trajectory and the magnetic field strength, and the gradient adjustment value is incorporated into the real-time adjustment plan.
[0125] The motion trajectory may be a motion path obtained by predicting the motion state of the chip to be transferred after the chip to be transferred is separated from the pickup head.
[0126] The actual motion trajectory may be an actual motion path of the chip to be transferred during the process of reaching the target substrate after the chip to be transferred separates from the pickup head and starts to move.
[0127] The secondary movement direction may be a direction corresponding to the secondary movement of the chip to be transferred when the chip to be transferred is affected by external factors after the chip to be transferred separates from the pickup head and starts to move.
[0128] The secondary motion speed may be a speed corresponding to the secondary motion of the chip to be transferred when the chip to be transferred is affected by external factors after the chip to be transferred separates from the pickup head and starts to move.
[0129] The airflow information may be information corresponding to the airflow that affects the movement of the chip to be transferred after the chip to be transferred separates from the pickup head and starts to move.
[0130] The airflow velocity may be the velocity of the airflow that affects the movement of the chip to be transferred after the chip to be transferred separates from the pickup head and starts to move.
[0131] The airflow intensity may be a numerical value corresponding to the strength of the airflow affecting the movement of the chip to be transferred after the chip to be transferred is separated from the pickup head and starts to move.
[0132] The secondary motion trajectory may be a motion path corresponding to the secondary motion of the chip to be transferred after the chip to be transferred is separated from the pickup head and starts to move, and the chip to be transferred is affected by external factors and undergoes secondary motion.
[0133] The gradient adjustment value may be a value determined when the intensity distribution of the magnetic field is adjusted to ensure that the chip to be transferred can accurately land on an ideal landing position of the target substrate after the chip to be transferred leaves the pickup head and starts to move.
[0134] Specifically, the initial release speed, chip weight, real-time adsorption intensity and magnetic field direction are predicted using machine learning and data analysis techniques to obtain the motion trajectory of the chip to be transferred after release. The real-time motion direction is extracted from the real-time motion information. The real-time motion direction and real-time motion speed are analyzed using machine learning and data analysis techniques to obtain the actual motion trajectory. The motion trajectory is matched with the actual motion trajectory. If the actual motion trajectory is inconsistent with the motion trajectory, the real-time transfer image is analyzed using an image analysis method to obtain the secondary motion direction and secondary motion speed. The airflow information is obtained from the gas monitoring device, and the airflow velocity and airflow intensity are extracted from the airflow information. The secondary motion direction, airflow velocity, airflow intensity, chip weight and secondary motion speed are analyzed using machine learning and data analysis techniques to obtain the secondary motion trajectory of each chip to be transferred. The motion trajectory is matched with the secondary motion trajectory to determine the degree of trajectory deviation. The degree of trajectory deviation and magnetic field intensity are analyzed using a mathematical analysis method to obtain a gradient adjustment value, and the gradient adjustment value is incorporated into the real-time adjustment scheme.
[0135] Through this solution, the real-time position of each chip to be transferred when it reaches the top of the target substrate is determined by real-time transfer images. The real-time position of each chip to be transferred is matched with the ideal landing point position to calculate the deviation angle of the chip to be transferred, that is, the angle difference between the actual position and the ideal position. According to the size and shape of each chip to be transferred, the rotation priority of the target substrate is determined to ensure that the rotation order of the substrate can optimize the positioning accuracy of the chip to be transferred to the greatest extent. According to the deviation angle and rotation priority, the rotation order of the target substrate is further determined to most effectively place the chip to be transferred to the ideal position. Through this dynamic adjustment process, the precise alignment of the chip to be transferred on the target substrate is ensured, and the accuracy and efficiency of the transfer process are optimized.
