Description

Technical Field

[0001] The present application relates to the technical field of production line control, and in particular to a method and system for controlling process parameters of carbon powder mixing. Background Art

[0002] Toner particles are typically polydisperse due to their uneven size and shape. The toner compounding process involves thoroughly and evenly mixing and melting various raw materials (primarily resins, pigments / dyes, charge control agents, waxes, etc.) to form a homogeneous mixture with the desired electrical, physical, and developing properties. This paves the way for subsequent pulverization, grading, and surface treatment.

Conventional testing generally uses traditional microscopes for manual testing, and the acquisition uses a relatively high-cost laser particle size analyzer.

[0022] Figure 1 This is a flow chart of a method for controlling carbon powder mixing process parameters proposed in an embodiment of the present application. DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] This application proposes a method for controlling the process parameters of carbon powder mixing, which is applicable to a carbon powder mixing production line. The production line includes a control terminal. The method is applicable to the control terminal. Optionally, it can also include a screw ejector, a feeding mechanism and other equipment. The method proposed in this application is applicable to the control terminal. The control terminal can be an industrial server, a PC (personal computer), etc., which is not limited here. Please refer to Figure 1 , the method proposed in this application comprises the following steps: S101: Obtain the product to be tested from the product end of the carbon powder mixing production line and place the product to be tested in a testing device, which includes a testing cavity of a testing cube, an ultrasonic generator arranged on one side of the testing cavity, and an ultrasonic sensor arranged opposite to the ultrasonic generator, wherein the product to be tested is placed and stacked in the testing cavity, and the height direction of the testing cavity is parallel to the direction of gravity.

[0025] As can be understood, in this embodiment, testing and production form a closed-loop control loop, therefore, specific product parameters need to be obtained at the product production end. During the toner production process, the dispersion of toner particles is a key indicator of toner production. Conventional testing generally uses traditional microscopes for manual inspection, and acquisition of the dispersion using expensive laser particle size analyzers. Manual inspection is time-consuming, while laser detectors are expensive.

[0026] In this embodiment, the detection equipment is embedded in the production line. After the product is output from the product end of the production line, the product can be automatically extracted from the production line and placed in the detection equipment. Specifically, the product to be detected is placed and stacked in the detection cavity, and the height direction of the detection cavity is parallel to the direction of gravity. At the same time, the detection data can be obtained by an ultrasonic generator arranged on one side of the detection cavity and an ultrasonic sensor arranged opposite to the ultrasonic generator. It should be noted that in this embodiment, each acquisition of the product to be detected can be quantitative, for example, filling the entire detection cavity. In this embodiment, the stacking height of the product to be detected in the detection cavity must be higher than the ultrasonic generator and the ultrasonic sensor. The transmitter and the sensor are arranged relative to each other, and the penetration attenuation is directly measured, which is more accurate than the reflection type.

[0027] S102: Applying vibration of a first unit time to the detection cavity based on a first vibration frequency, and obtaining a first ultrasonic attenuation rate based on an ultrasonic sensor.

[0028] As can be understood, in this embodiment, after the product to be tested accumulates in the detection chamber, the detection chamber can be vibrated for a first unit time. Since the height direction of the detection chamber is parallel to the direction of gravity at this time, the product to be tested is affected by gravity, and the carbon powder naturally settles under the action of gravity. In other words, the carbon powder particles form aggregated particles of varying sizes due to different degrees of aggregation. Based on Stokes' law, large particles settle faster and accumulate at the bottom of the chamber, while small particles / agglomerates are suspended in the upper part due to Brownian motion. In other words, the carbon powder particles undergo stratification within the detection chamber.

[0029] As will be appreciated, the ultrasonic sensor and ultrasonic generator are positioned perpendicular to the direction of gravity. Therefore, the acoustic wave transmission path between the ultrasonic sensor and the ultrasonic generator is also parallel to the layered plane of the carbon powder particles. The acoustic wave transmission attenuation is relatively uniform. At this point, a first ultrasonic attenuation rate can be obtained based on the ultrasonic sensor.

[0030] In some embodiments, prior to testing, the detection cavity may be subjected to vibration for a second unit time at a second vibration frequency. It will be appreciated that the purpose of the second vibration frequency is to make the product to be tested fit more closely within the detection cavity. Therefore, the second vibration frequency is lower than the first vibration frequency, and the second unit time is lower than the first unit time, thereby minimizing delamination of the product to be tested when the second vibration frequency is applied.

[0031] S103: Turn over the detection cavity so that the height direction of the detection cavity is perpendicular to the direction of gravity.

[0032] It can be understood that in this embodiment, after flipping the detection cavity, the height direction of the detection cavity is now perpendicular to the direction of gravity. Therefore, the ultrasonic sensor and the ultrasonic generator are separated from the detection unit at this time. At this time, the sound wave transmission line between the ultrasonic sensor and the ultrasonic generator is perpendicular to the stratification plane of the carbon powder particles.

[0033] In some embodiments, in order to ensure the degree of fit after flipping, vibration for a second unit time based on a second vibration frequency may be applied to the detection cavity.

[0034] S104: Obtain a second ultrasonic attenuation rate based on the ultrasonic sensor, and obtain a carbon powder particle distribution index based on the first ultrasonic attenuation rate and the second ultrasonic attenuation rate.

[0035] Understandably, because the product under test exhibited stratification under the first vibration frequency, the aggregation of carbon powder particles of the same size resulted in a distinct interface in the ultrasonic testing results. Furthermore, the aggregation of carbon powder particles of the same size increased their blocking effect on sound waves smaller than the particles, i.e., the agglomerates enhanced sound wave scattering. Consequently, the second ultrasonic attenuation rate was significantly lower than the first. In other words, the more pronounced the stratification, the greater the impact on the attenuation of ultrasonic transmission.

[0036] Since the degree of carbon powder particle aggregation directly affects the stratification, and the stratification directly affects the attenuation of ultrasonic transmission, an expression for the relationship between ultrasonic attenuation and the degree of carbon powder particle aggregation can be established.

[0037] For example, in this embodiment, the relationship between ultrasonic attenuation and the degree of aggregation of carbon powder particles can be characterized using a machine learning approach. Specifically, in this embodiment, an ultrasonic attenuation rate-carbon powder distribution index artificial intelligence model can be established, and the artificial intelligence model can be trained based on historical experimental data. The historical data can be obtained through historical experiments. The trained ultrasonic attenuation rate-carbon powder distribution index artificial intelligence model is obtained, and the first ultrasonic attenuation rate and the second ultrasonic attenuation rate are introduced into the artificial intelligence model. Based on the output of the artificial intelligence model, the carbon powder particle distribution index is obtained.

[0038] In other embodiments, other methods may be used, such as mathematical calculations, which are not limited here.

[0039] S105: Regulating the production line based on the toner distribution index.

[0040] It is understandable that the control method in this embodiment can also adopt an artificial intelligence method. Specifically, a carbon powder mixing process parameter model can be established, and the parameter model includes mixing temperature, mixing time, screw speed, feed rate, carbon powder and additive ratio, and carbon powder particle distribution index. The carbon powder mixing process parameter model is trained based on historical production data. Then, the correlation between mixing temperature, mixing time, screw speed, feed rate, carbon powder and additive ratio and carbon powder particle distribution index is obtained. Then, before the carbon powder mixing process begins, the carbon powder particle distribution index requirement of the target carbon powder is obtained and the carbon powder particle distribution index requirement is input into the carbon powder mixing process parameter model. Based on the output results of the carbon powder mixing process parameter model, the target mixing temperature, target mixing time, target screw speed, target feed rate, and target carbon powder and additive ratio are obtained. Finally, based on the output results of the carbon powder mixing process parameter model, the current mixing temperature, current mixing time, current screw speed, current feed rate, and current carbon powder and additive ratio are dynamically adjusted.

[0041] Optionally, in this embodiment, the first ultrasonic attenuation rate and the second ultrasonic attenuation rate are obtained, and the first ultrasonic attenuation rate and the second ultrasonic attenuation rate are compared with the target ultrasonic attenuation rate. If the first ultrasonic attenuation rate and the second ultrasonic attenuation rate are greater than the target ultrasonic attenuation rate, it can be determined that the main influencing factor of the particles is that the particles are too fine or agglomerated. At this time, the target screw speed and the target feed rate are preferentially regulated during the regulation process.

[0042] The embodiment of the present application proposes a method for controlling the parameters of a carbon powder mixing process. First, the product to be tested is obtained from the product end of the carbon powder mixing production line, and the product to be tested is placed in a detection device. The detection device includes a detection cavity of a detection cube, an ultrasonic generator arranged on one side of the detection cavity, and an ultrasonic sensor arranged opposite to the ultrasonic generator. Then, a vibration of a first unit time is applied to the detection cavity based on a first vibration frequency, and a first ultrasonic attenuation rate is obtained based on the ultrasonic sensor. Then, the detection cavity is flipped so that the height direction of the detection cavity is perpendicular to the gravity direction. Then, a second ultrasonic attenuation rate is obtained based on the ultrasonic sensor, and a carbon powder particle distribution index is obtained based on the first ultrasonic attenuation rate and the second ultrasonic attenuation rate. Finally, the production line is controlled based on the carbon powder distribution index. The embodiment of the present application proposes a method for controlling the parameters of a carbon powder mixing process. The method uses the difference in ultrasonic attenuation under changes in the direction of gravity to evaluate the dispersion of carbon powder particles. It is faster than manual microscope detection and does not require a laser detector, saving production costs.
