Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent lubrication, in particular to a non-standard equipment servo module automatic lubrication method, system, medium and electronic equipment. BACKGROUND

[0002] The statements in this section merely provide background technology related to the present application and do not necessarily constitute prior art.

[0003] The servo module of non-standard equipment (i.e. non-standard equipment, not equipment manufactured according to unified industry standards and specifications, but equipment designed and manufactured by users according to their needs) is widely used in non-standard automation equipment. With the increase of equipment running speed and frequency, the service life of the servo module is greatly tested. With the demand of production, non-standard equipment has no time to be fully maintained and lubricated. Non-standard modules lack lubrication and are more dirty, causing the servo module to be prone to nut internal ball wear, dust cover expansion, and serious screw surface wear.

[0004] The industry usually maintains the servo module for more than 30 minutes per module, which is a long lubrication and maintenance time, conflicting with the fast and long-cycle production rhythm. The latest practice in the industry is to lead the oil injection pipeline outside, guide the grease slot on the sheet metal, and concentrate to a centralized control solenoid valve island, which can realize automatic oiling of the entire pipeline. However, the entire control method is semi-automatic, cannot monitor the running status of the servo module, and cannot ensure that the servo can lubricate the entire servo module system in time when it needs lubrication.

[0005] For example, patent number CN215448271U discloses a lubrication transmission early warning device, which is fixed by setting a receiving groove, a first telescopic rod and a fixed plate bolt, and is adjusted and fixed according to different needs, facilitating the use of workers, and can be detected in real time. By setting a torque sensor, it is convenient to detect the torque during machine use, and it is convenient to judge the need of workers to add lubricating oil to avoid wear caused by lack of lubricating oil for a long time. By setting a second telescopic rod and a spring, the device is convenient to use, and the workers are convenient to install and use the torque sensor;

[0006] However, the inventors found that the above-mentioned technology mainly uses a torque sensor to collect torque data, and manually reads the data and judges whether the torque is normal based on experience, and further judges whether to add lubricating oil, which requires a lot of human involvement and is time-consuming and laborious. Moreover, manual analysis of torque data is mostly based on spot check data, which cannot achieve continuous torque detection, often cannot exclude the influence of abnormal torque fluctuation, and is extremely likely to judge short-term torque fluctuation as needing lubrication, thereby causing incorrect lubrication instructions. SUMMARY

[0007] In order to solve the problems of the prior art, the present application provides a non-standard equipment servo module automatic lubrication method, system, medium and electronic equipment, which realizes full-automatic lubrication of the non-standard equipment servo module, effectively avoids false positives, and improves the accuracy of servo module lubrication control.

[0051] The present application will be further described below in conjunction with the accompanying drawings and embodiments.

[0052] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0053] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and it should also be understood that when the terms "comprise" and / or "include" are used in the specification, there is a presence of a feature, step, operation, device, component and / or combinations thereof.

[0054] The embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0055] Embodiment 1:

[0056] In order to improve the stability of the servo module operation, and real-time monitoring of the servo module operation, timely lubrication, through monitoring the servo torque value to determine whether the entire servo module needs to be lubricated, real-time monitoring of the operation of the entire servo module, specifically, as shown in Figure 1 .

[0057] In this embodiment, the running servo pressure of the servo module (servo motor and its matching components) after lubrication is monitored in advance, and a set threshold value is set (in this embodiment, the set threshold value is set differently according to the servo condition, for example, the sampling threshold value of the pressurized servo module when the load is zero is the minimum torque T min , the sampling threshold value of the translation servo module is the maximum torque T max , and the final set threshold value is 130% to 150% of the sampling threshold value, for example, the set threshold value of the pressurized servo module is (1.3-1.5)*T min , and the set threshold value of the translation servo module is (1.3-1.5)*T max .

[0058] In this embodiment, the feedback of the torque is monitored in real time during the operation of the device, and if the servo torque exceeds the set threshold value, the entire servo module is lubricated. At the same time, low-viscosity grease with a viscosity of 12 mPa·s to 15 mPa·s is selected to fully lubricate the nut and slider in the entire servo module, achieve low-friction performance, and enable the entire servo module to operate safely and stably for a long time. Low-viscosity lubricating oil has low adhesion and high permeability, preventing dust and debris from entering the slider and nut, and preventing damage to the ball circulation and slide of the slider and nut.

[0059] More specifically, the following examples are provided:

[0060] For example, the pressurized servo module is monitored, and the torque signal during the pressurized servo rising (i.e., idling) is obtained, for example, 80 N·m. After this calibration, the threshold value of the entire module is set to (1.3 or 1.5)*80 N. When the rising edge signal exceeds the standard torque for 3-5 minutes (i.e., when the set threshold value is exceeded for 3-5 minutes, continuous torque sampling is used at this time), the entire servo module is judged to be stuck, and the lubricating oil is injected into the servo module. After 10 minutes of lubrication, the torque of the servo motor after sufficient lubrication is judged to determine the effect of the lubrication. If the torque does not decrease after lubrication, an alarm signal is generated, and the pressurized servo module is abnormal and needs to be checked. The present application realizes closed-loop monitoring and automatic feedback of the servo module lubrication, and improves the accuracy of lubrication control by setting the threshold value and the duration after exceeding the set threshold value.

[0061] It can be understood that in other implementations, interval torque sampling can also be used. If the torque values sampled continuously for multiple times all exceed the set threshold value, the entire servo module sticking state is judged, the lubricating grease is injected into the servo module, and after 10 minutes of lubrication, the effect of lubrication is judged by judging the state of the servo motor torque after sufficient lubrication. If the torque does not decrease after lubrication, an alarm signal is generated. At this time, the press servo module state is abnormal and needs to be checked, realizing closed-loop monitoring and automatic feedback of the servo module lubrication. Moreover, by setting the threshold value and the number of times after exceeding the set threshold value, false alarm situations can be effectively avoided, and the accuracy of lubrication control is improved.

[0062] It can be understood that the number of times here can be set according to specific working conditions, and is preferably set according to the sampling interval size. For example, if sampling is performed once every 2 seconds, the number of times can be selected to be between 90 and 150, and preferably can be selected to be 120 times.

[0063] It can be understood that 3 minutes to 5 minutes here are preferred set values, and a person skilled in the art can select them according to specific working conditions. For example, they can be 3 minutes to 4 minutes, or other arbitrary single values or interval values, which will not be described here.

[0064] It can be understood that 10 minutes here is a preferred set value, and a person skilled in the art can select it according to specific working conditions. For example, it can be 15 minutes or 20 minutes, etc., or other arbitrary single values or interval values, which will not be described here.

[0065] Compared with the traditional servo module lubrication scheme, the present application can realize closed-loop control of lubrication, ensure the timeliness and effectiveness of the entire servo module operation, avoid the protection of the servo module due to insufficient lubrication caused by insufficient lubrication or insufficient maintenance time during daily maintenance, ensure the long-term stable operation of the servo module, reduce the equipment operation failure, and improve the equipment operation efficiency.

[0066] By using the scheme described in the present embodiment, the time loss of oil injection is reduced from 1 time / month to 1 time / year, and the screw damage is reduced from 1 time / year to 1 time / 5 years.

[0067] In the present embodiment, the control logic is as shown in Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 Preferably, the lubrication time and the minimum trigger interval between two lubrications are set.

[0068] Optionally, the lubrication time can be obtained as an optimal value or an optimal interval value according to an empirical value or big data analysis.

[0069] Optionally, the minimum trigger interval between two lubrications can be the minimum or average value of multiple automatic lubrication intervals. Those skilled in the art can choose according to the specific working conditions, as long as normal lubrication can be guaranteed, which will not be elaborated here.

[0070] In this embodiment, a preferred solution is provided, including:

[0071] The lubrication time depends on the entire module stroke and the penetrability of the lubricant. Generally speaking, the amount of lubricant extruded from a single module is fixed.

[0072] The automatic lubrication interval is also to prevent too much lubricant from being squeezed in at one time when the lubricant penetration is insufficient. It is generally set to 30 minutes. For modules with particularly long strokes, this time needs to be increased.

[0073] The minimum interval between two triggers is to prevent misinterpretation of information due to excessive lubricant injection. Generally, the lubrication interval for modules is 30 days at full production, but in the event of system deterioration, the time is compressed to 15 days.

[0074] Example 2:

[0075] like Figure 7 As shown, Embodiment 2 of the present invention provides an automatic lubrication system for a non-standard equipment servo module, comprising:

[0076] The data acquisition module is configured to acquire the torque of the servo module of non-standard equipment.

[0077] The lubrication control module is configured to generate a signal requiring lubrication when the torque of the servo module exceeds a set threshold, so that the lubrication system supplies oil to the servo module.

[0078] More specifically, in the data acquisition module, the torque of the servo module can be continuously sampled in real time or discretely sampled. Those skilled in the art can choose the appropriate design based on the specific working conditions, which will not be elaborated here.

[0079] More specifically, the lubrication control module includes the following solutions:

[0080] Set a threshold value (in this embodiment, the threshold value is set differently depending on the servo condition; for example, the sampling threshold for the pressure servo module when it is unloaded is the minimum torque value T). min The sampling threshold of the translation servo module is the maximum torque T during operation. max The final set threshold is 130% to 150% of the sampling threshold. For example, the set threshold for the pressurized servo module is (1.3-1.5)*T. min The threshold value for the translation servo module is (1.3-1.5)*T. max ;

[0081] In this embodiment, the feedback of the torque is monitored in real time during the operation of the device. If the servo torque exceeds the set threshold, the entire servo module is lubricated. At the same time, low viscosity grease with a viscosity of 12 mPa·s to 15 mPa·s is selected to fully lubricate the nut slider in the entire servo module, achieve low friction performance, and enable the entire servo module to operate safely and stably for a long time. The low viscosity lubricating grease has low adhesion and high permeability, prevents dust and debris from entering the inside of the slider and nut, and avoids damage to the ball circulation and slide of the slider and nut.

[0082] More specifically, the following examples are provided:

[0083] For example, when the pressurized servo module is pressurized, the torque signal during the pressurized servo rising (i.e., idling) is monitored, for example, 80 N·m is obtained. After this calibration, the threshold of the entire module is set to (1.3 or 1.5) * 80 N. When the rising edge signal exceeds the standard torque for 3-5 minutes (i.e., when the set threshold is exceeded for 3-5 minutes, continuous torque sampling is used at this time), the jamming state of the entire servo module is determined, and the lubricating oil is injected into the inside of the servo module. After 10 minutes of lubrication, the effect of the lubrication is determined by judging the state of the servo motor torque after the lubrication. If the torque after the lubrication has not decreased, an alarm signal is generated. At this time, the state of the pressurized servo module is abnormal and needs to be checked. The closed-loop monitoring and automatic feedback of the servo module lubrication are achieved. Moreover, the accuracy of the lubrication control is improved by setting the threshold and the time after exceeding the set threshold in this embodiment.

[0084] It can be understood that in other implementations, interval torque sampling can also be used. If the torque value sampled continuously for multiple times exceeds the set threshold, the jamming state of the entire servo module is determined, the lubricating oil is injected into the inside of the servo module, and after 10 minutes of lubrication, the effect of the lubrication is determined by judging the state of the servo motor torque after the lubrication. If the torque after the lubrication has not decreased, an alarm signal is generated. At this time, the state of the pressurized servo module is abnormal and needs to be checked. The closed-loop monitoring and automatic feedback of the servo module lubrication are achieved. Moreover, the accuracy of the lubrication control is improved by setting the threshold and the number of times after exceeding the set threshold in this embodiment, which can effectively avoid false alarms.

[0085] It can be understood that the number of times here can be set according to the specific working conditions, and the size of the sampling interval is preferably set, for example, sampling once every 2 seconds, and the number of times can be valued between 90-150, and preferably 120 times.

[0086] It can be understood that 3min-5min is a preferred setting value, and those skilled in the art can select according to specific working conditions, for example, it can be 3min-4min, or other arbitrary single value or interval value, which will not be repeated here.

[0087] It can be understood that 10min is a preferred setting value, and those skilled in the art can select according to specific working conditions, for example, it can be 15min or 20min, etc., or other arbitrary single value or interval value, which will not be repeated here.

[0088] By adopting the scheme described in the embodiment, the time loss of oiling is reduced from 1 time / month to 1 time / year, and the screw damage is reduced from 1 time / year to 1 time / 5 years.

[0089] Optionally, in the embodiment, the lubrication time and the minimum trigger interval of twice lubrication are preferably set.

[0090] It can be understood that the lubrication time can be obtained as an optimal value or an optimal interval value according to experience value or big data analysis.

[0091] It can be understood that the minimum trigger interval of twice lubrication adopts a minimum value or an average value of multiple automatic lubrication time intervals, and those skilled in the art can select according to specific working conditions, as long as normal lubrication can be ensured, which will not be repeated here.

[0099] The control logic, as shown in Figure 9

[0100] The servo motor sends the torque signal to the PLC controller through the servo motor driver by monitoring the torque signal when the pressure servo rises (i.e. idling), for example, 80 N·m (i.e. sampling threshold value) is obtained, and after calibration, the set threshold value of the whole module is set to (1.3 or 1.5) * 80 N. When the rising edge signal exceeding the standard torque is obtained for 3-5 min, it is judged that the whole servo module is stuck, the PLC controller controls the opening of the electromagnetic valve, and the lubricating oil is injected into the servo module through the valve island through the air pressure, and after 10 min of lubrication, the torque state of the servo module after sufficient lubrication is judged, the effect of lubrication is judged, and if the torque after lubrication does not decrease, the PLC controller gives an alarm signal, at this time the device module state is abnormal and needs to be checked, realizing closed-loop monitoring and automatic feedback of the servo module lubrication, and the embodiment improves the accuracy of lubrication control by setting the threshold value and the time setting after exceeding the threshold value.
