[0002] Vibration grinding machine is a mechanical device that uses the principle of vibration for surface treatment. Its working principle is to drive the eccentric wheel through the motor to generate high-frequency vibration, so that the workpiece in the working container and the grinding medium produce relative movement, thereby achieving the effects of grinding, deburring, polishing, etc. on the surface of the workpiece. Vibration grinding machine is widely used in hardware, plastics, electronics, jewelry and other industries for surface treatment of parts.

[0003] During the working process of the vibration grinder, the workpiece and the grinding medium continuously collide and rub in the container, which can effectively remove burrs, oxide layers and dirt on the surface of the workpiece, and achieve a smooth polishing effect. Compared with traditional manual grinding, vibration grinding has the advantages of high efficiency, good consistency, and batch processing. It can process a large number of small workpieces at the same time and is suitable for large-scale production. In addition, the vibration grinder is easy to operate and has low maintenance costs. It is an important equipment for many manufacturing companies to improve the efficiency and quality of surface treatment.

Some temperature-sensitive materials may deteriorate or fail due to overheating. Grinding media and containers may accelerate wear at high temperatures and shorten equipment life.

[0030] The vibration grinding module 10 is mainly used to contain corresponding abrasives and generate controlled vibrations to grind the workpiece in the abrasives.

[0031] The material moving module 20 is mainly used to move the workpiece during the grinding process, by moving the workpiece to be ground into the vibration grinding module 10 for grinding, and moving the ground workpiece out of the vibration grinding module 10 to achieve automatic material moving.

[0032] The processing control module 30 is mainly used to process and control data of the vibration grinding module 10 and the material moving module 20 .

[0033] The grinding container 11 is mainly used to contain abrasives and workpieces, and vibrates under the drive of the eccentric fan 13 so that the abrasives produce a grinding effect on the workpieces.

[0034] Each through hole 12 is mainly used to allow air and fine powder generated by grinding to pass through, and the size of the through hole should be smaller than the abrasive and the workpiece.

[0035] The eccentric fan 13 is mainly used to rotate eccentrically and drive the grinding container 11 to vibrate, and at the same time generate an airflow at a certain speed to take away the powder and hot air generated during grinding.

[0036] The eccentric fan 13 can be formed by fixing a counterweight block of a certain mass to one of the blades of a common fan, so that the eccentric fan 13 drives the grinding container 11 to vibrate when rotating.

[0037] The air guide channel 14 is mainly used to guide the grinding powder and hot air into the air filter module 15 .

[0039] The support frame 16 is mainly used to elastically support the grinding container 11 so that it can vibrate under eccentric motion.

[0040] Through the above technical scheme, the vibration grinding filter control system can grind the workpiece by generating vibration through the eccentric fan, and can take away the dust and hot air generated by grinding through the eccentric fan, which can reduce environmental pollution during grinding and improve the grinding effect.

[0041] Furthermore, the material transfer module 20 includes a feeding module 21, a screening module 22, a gloss detection module 23 and a discharging module 24, the feeding module 21 and the screening module 22 are respectively connected to the vibration grinding module 10 for material transfer, the gloss detection module 23 is respectively arranged in the feeding module 21 and the screening module 22, and the screening module 22 is respectively connected to the discharging module 24 and the feeding module 21 for material transfer.

[0042] The feeding module 21 is mainly used to automatically convey the workpiece to be ground into the grinding container 11 of the vibration grinding module 10 .

[0043] The screening module 22 is mainly used to screen the workpieces according to the workpiece gloss detection results of the gloss detection module 23. If a workpiece with unqualified gloss is found, it can be returned to the grinding container 11 through the feeding module 21 for further grinding, or the workpiece that fails to be ground can be discarded.

[0044] The gloss detection module 23 is mainly used to detect the glossiness of the workpiece.

[0045] The discharging module 24 is mainly used to output workpieces with qualified glossiness to other processes.

[0046] The feeding module 21 and the discharging module 24 can be a vibration plate.

[0047] Through the above technical scheme, the vibration grinding filter control system can realize the automation of workpiece processing by integrating feeding, screening, gloss detection and discharging functions. The two-way connection between the screening module and the discharging module and the feeding module enables the system to flexibly process materials according to the detection results, return unqualified products for reprocessing, and improve the product yield.

[0048] Furthermore, the vibration grinding filter control system also includes a vibration grinding control strategy, and the vibration grinding control strategy includes the following steps: A1, placing a preset abrasive in the grinding container 11; Abrasives are grinding materials selected according to the workpiece and grinding process requirements, and can have different shapes, materials and sizes.

[0049] A2, adding workpieces into the grinding container 11 through the feeding module 21; The workpiece is a component that needs to be ground; A batch of workpieces can be automatically fed into the grinding container 11 via the feed module 21 .

[0050] A3, controlling the rotation of the eccentric fan 13 through the processing control module 30 according to a preset initial fan speed; The initial fan speed is a preset default speed when the eccentric fan 13 is started, which can be set based on experience or data; In a conventional vibration grinder, the vibration frequency of the grinder is adjusted by adjusting the rotation speed of the eccentric motor, and usually the rotation speed and the vibration frequency of the eccentric motor are positively correlated. Similarly, in the present invention, adjusting the rotation speed of the eccentric fan 13 can also achieve the effect of adjusting the vibration frequency.

[0051] A4, the grinding container 11 is driven to vibrate by the eccentric fan 13 so that the abrasive grinds each workpiece; When the eccentric fan 13 rotates, the eccentric block installed on one of the blades can drive the grinding container 11 to vibrate during rotation, so that the abrasive and the workpiece in the grinding container 11 vibrate together to produce a grinding effect.

[0052] A5, the eccentric fan 13 sucks the grinding dust generated by grinding through each of the through holes 12 and transfers the grinding dust through the ventilation channel 14 to the air filter module 15 for filtering; While the eccentric fan 13 drives the grinding container 11 to vibrate and grind the workpiece, the eccentric fan 13 can generate airflow and suck away the grinding dust generated during grinding through the through hole 12 at the bottom of the grinding container 11, and filter the dust through the air filter module 15 to reduce the pollution of the grinding dust to the surrounding air.

[0053] A6, the eccentric fan 13 sucks the hot air generated by grinding through the through holes 12 to cool the abrasive and the workpieces.

[0054] While the eccentric fan 13 sucks away the grinding dust, the hot air generated during grinding will also be taken away at the same time, so that the abrasive and the workpiece can be maintained at a suitable temperature to ensure the grinding effect.

[0055] Through the above steps, the vibration grinding and filtering machine control system can not only generate vibration for grinding through the rotation of the eccentric fan, but also realize dust suction, air filtration and hot air discharge at the same time, thereby improving the processing efficiency and environmental cleanliness. Through the cooling function, the overheating problem is effectively prevented, the workpiece quality and equipment life are guaranteed, the working efficiency, processing quality and environmental friendliness of the entire system are improved, and the energy consumption and maintenance costs are also reduced.

[0056] Furthermore, the vibration grinding filter control system also includes a vibration grinding adjustment strategy, and the vibration grinding adjustment strategy includes the following steps: B1, the gloss data of the workpiece obtained by the gloss detection module 23 in the feeding module 21 is defined as the initial gloss data of the workpiece; The initial glossiness data of the workpieces are glossiness data of a batch of workpieces to be ground, and are obtained by performing a random inspection or a full inspection of the glossiness of the batch of workpieces.

[0057] B2, when the eccentric fan 13 drives the grinding container 11 to vibrate, the current time is obtained and defined as the grinding start time; The grinding start time is the time when the eccentric fan 13 starts to rotate, that is, the time when the grinding operation starts.

[0058] B4, randomly selecting a number of workpieces through the screening module 22 and obtaining corresponding gloss data through the gloss detection module 23 and defining it as detecting gloss data and obtaining corresponding detection time; The detected glossiness data is a data set of glossiness of each randomly selected workpiece.

[0059] The detection time is the corresponding time when the glossiness of each workpiece is detected.

[0060] B5, calculate the corresponding average glossiness according to the average of the glossiness data; The average detected gloss is the average value of the detected gloss data, that is, the average gloss value of the workpieces randomly inspected during the grinding process.

[0061] The grinding completion degree is the grinding degree of the current workpiece judged based on the average detected glossiness, which is used to reflect the progress of the grinding operation; For example, the difference between the average detected gloss and the average initial gloss can be divided by the difference between the target gloss and the average initial gloss.

[0062] B6, determining the corresponding grinding time by calculating the difference between the grinding start time and the detection time; The grinding time is the time between the grinding start time and the detection time, that is, the time spent in the grinding operation at the detection time.

[0063] B7, adjusting the rotation speed of the eccentric fan 13 according to the average initial glossiness, the average detected glossiness, the preset target glossiness, the grinding consumption time and the preset grinding process time.

[0064] The target glossiness is the glossiness that the workpiece needs to be polished to; The grinding process duration is the maximum duration that the grinding operation can consume, which can be set based on experience or process; The grinding progress can be judged according to the average initial gloss, the average detected gloss and the preset target gloss, and the remaining available grinding time can be calculated according to the grinding time consumed and the grinding process time. When the remaining time is sufficient, the rotation speed of the eccentric fan can be reduced to reduce the grinding speed so as to reduce energy consumption and noise. When the remaining time is not sufficient, the rotation speed of the eccentric fan can be increased to increase the grinding speed.

[0065] Through the above steps, the vibration grinding filter control system can form a closed-loop feedback system through the initial gloss measurement to random sampling detection, and then adjust the fan speed according to the grinding completion status. The whole process can not only dynamically adjust the grinding frequency according to the actual situation of the workpiece, but also control the grinding time to avoid excessive or insufficient grinding.

[0067] B702, determining the corresponding estimated completed revolutions according to the average detected glossiness and the preset glossiness fan revolutions corresponding to the workpiece; The glossiness fan revolution comparison data is data corresponding to the workpiece to be ground, and reflects the glossiness data corresponding to the workpiece under different cumulative revolutions of the eccentric fan 13; because the rotation speed and vibration frequency of the eccentric fan 13 are positively correlated, and thus the cumulative revolutions and cumulative vibration times are positively correlated, the grinding amount in the grinding process can be quantified by the revolutions of the eccentric fan 13 when the amplitude remains unchanged, and a data relationship of positive correlation is formed between the revolutions of the eccentric fan 13 and the glossiness of the workpiece, and the revolutions of the eccentric fan 13 can be estimated by integrating the revolutions according to the duration, or can be obtained by accurate measurement by a specific revolution sensor; For different workpieces and different grinding processes, the corresponding glossiness fan speed comparison data needs to be measured separately; The estimated completed revolutions are the revolutions determined based on the glossiness and glossiness fan revolutions comparison data, reflecting the possible fan revolutions that the workpiece may experience under the corresponding glossiness.

[0068] B703, calculating the corresponding estimated remaining revolutions according to the difference between the estimated completed revolutions and the preset estimated total fan revolutions; The estimated total number of fan revolutions is the cumulative number of fan revolutions required to achieve a qualified glossiness for the workpiece and its grinding process, which can be measured through experiments; The estimated remaining number of revolutions is the number of revolutions of the eccentric fan 13 that is estimated to be required based on the current grinding condition of the workpiece.

[0069] B704, determining the corresponding fan target speed according to the quotient of the estimated remaining revolutions and the remaining grinding time; The fan target speed is the quotient of the estimated remaining revolutions and the remaining grinding time, reflecting the fan speed required to complete the grinding in the remaining time.

[0070] B705, adjusting the speed of the eccentric fan through the processing control module 30 according to the fan target speed; The rotation speed of the eccentric fan is adjusted so that the workpiece can be ground within the remaining grinding time.

[0071] Through the above steps, the vibration grinding filter control system can calculate the remaining grinding time and combine the comparison data of glossiness and fan speed. The system can accurately estimate the completed and remaining processing volume. It not only takes into account the time factor, but also combines the actual state of the workpiece with the expected goal, so as to more accurately determine the required fan target speed, so that the grinding operation can be completed in time and the grinding efficiency is guaranteed.

[0072] Furthermore, the vibration grinding adjustment strategy further includes the following steps for determining the glossiness fan speed reference data and estimating the total fan speed: C1, measure the average gloss of the preset workpiece sample and define it as the initial average gloss of the sample; The workpiece sample is a pre-selected workpiece used to measure the glossiness fan speed reference data and estimate the total fan speed; The sample initial average gloss is a data set of the average gloss of each workpiece sample.

[0073] C2, grinding the workpiece sample with the corresponding abrasive by the vibration grinding module 10, and rotating the eccentric fan 13 at a preset test speed, obtaining the current time and defining it as the initial time of the test; The test speed is a preset fan speed, which is used to measure the glossiness fan speed reference data and estimate the total fan speed of the workpiece, and can be set based on experience; The test initial time is the time when the measurement test starts, that is, the time when the eccentric fan 13 starts to rotate.

[0074] C3, continuously sampling the workpiece samples at a preset sampling interval to obtain sampling gloss data and calculate the corresponding sampling average gloss, and at the same time determine the corresponding sampling time; The sampling interval is a pre-set time interval used to determine the frequency of spot checking workpiece samples; The sampling gloss data is the gloss data of each sample workpiece sampled; The sampling time is the time corresponding to the sampled gloss data at the time of sampling.

[0075] C4, if the sampled average glossiness is not less than the preset test target glossiness, the eccentric fan 13 is stopped, and the current time is obtained and defined as the test end time; The test target gloss is the gloss that the sample workpiece needs to achieve; The test end time is the time when the sample workpiece reaches the test target glossiness and the eccentric fan 13 stops rotating.

[0076] C5, calculate the corresponding duration based on the difference between the initial time of the experiment and each sampling time and define it as the sampling duration; The sampling time is the grinding time experienced by each sample workpiece during each sampling.

[0077] C6, calculate the cumulative fan speed at the corresponding sampling moment by multiplying each sampling time by the test speed; The cumulative number of fan revolutions at the sampling moment is the cumulative number of revolutions of the eccentric fan 13 experienced by the sample workpiece at the sampling moment.

[0078] C7, calculate the corresponding duration according to the difference between the initial time and the end time of the test and define it as the estimated total grinding time; The estimated total grinding time is the time elapsed between the start time of the test and the end time of the test, reflecting the time required for the eccentric fan 13 to complete the grinding of each sample workpiece at a fixed test speed.

[0079] C8, calculate the corresponding estimated total fan speed by multiplying the estimated total grinding time and the test speed; The estimated total number of fan revolutions is the estimated total number of revolutions of the eccentric fan 13 that the sample workpiece needs to experience to complete grinding.

[0081] Through the above steps, the vibration grinding filter control system can establish a detailed and reliable corresponding data of glossiness and fan speed by performing regular sampling and data recording during the grinding of test samples, thereby providing effective data reference for subsequent actual production processes.
