[0002] The ball nut is a key component in the ball screw pair. It is used in combination with the ball screw to form a ball screw pair, realizing the conversion between rotational motion and linear motion.

[0018] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0019] A lubrication control method based on ball nut production automatically lubricates the ball nuts by acquiring image detection information, weight detection values, liquid level detection values, clamping pressure values, sound detection information, vibration detection information, irradiation detection information, oil delivery pipeline diameter values, and oil delivery length values. This ensures that the lubrication method and amount of each ball nut remain consistent, and automatically issues an early warning when oiling anomalies occur, thereby improving the overall product quality of the ball nuts and automatically detecting the oiling status.

[0020] Reference Figure 1The embodiment of the present invention discloses an oiling control method based on ball nut production, which includes: Step S100: Acquire image detection information on the conveyor belt during the production process.

[0021] The image detection information refers to image information obtained by performing image detection on a conveyor belt used to transport ball nuts during the production process, and the image detection information is obtained through detection by a camera.

[0022] Step S101: When a preset ball nut feature is matched in the image detection information, the image detection information is identified according to the ball nut feature to obtain nut image information.

[0023] The ball nut features refer to the shape, color, and other characteristics of the ball nut under different placement conditions. The ball nut features are obtained through pre-input. The nut image information refers to the image information of the ball nut's position.

[0024] When the preset ball nut features are matched in the image detection information, it means that the conveyor belt has transported the ball nut to the predetermined position. Therefore, the image detection information is identified by the ball nut features to obtain the nut image information for subsequent use.

[0025] Step S102: Determine nut specification information and nut location points based on the nut image information.

[0026] The nut specification information refers to the specifications of the ball nut, and the nut location point refers to the location of the ball nut. The specifications of the ball nut features matched to the nut image information are retrieved and used as the nut specification information. The relative position of the nut image information in the image detection information is identified and read. The actual position is calculated based on the relative position of the image and the preset camera shooting ratio. The obtained actual position is then used as the nut location point for subsequent use.

[0027] Step S103: Based on the nut position point, a preset clamping device is controlled to clamp the ball nut and place it on a preset oiling device, and a weight detection value is obtained.

[0028] The clamping device refers to a manipulator for clamping the ball nut. The clamping device is pre-set near the conveyor belt and the oiling device, making it easy to clamp the ball nut from the conveyor belt to the oiling device. The oiling device refers to a device for oiling the ball nut. The oiling device includes a placement table 1 for placing the ball nut, an oil storage tank 2 for storing oil, an oil pipeline 3 for transporting lubricating oil, an oil spray head 4 for spraying lubricating oil onto the ball nut, and an oiling pump 5 for pumping lubricating oil from the oil storage tank 2 to the oil spray head 4. The weight detection value refers to the weight value obtained by detecting the weight on the placement table 1. The weight detection value is detected by a weight sensor pre-set on the placement table 1.

[0029] By controlling the preset clamping device, the ball nut at the nut position point is clamped and placed on the preset oiling device, and the weight detection value is obtained in real time for subsequent use.

[0030] Step S104: Determine the weight reference range and oiling control information according to the nut specification information.

[0031] The weight reference interval refers to the reference interval corresponding to the weight of the ball nut of the specification under normal circumstances, and the oiling control information refers to the duration and weight of oiling required for the ball nut of the specification under normal circumstances.

[0032] Different nut specifications correspond to different weight reference intervals and oiling control information. These weight reference intervals and oiling control information are retrieved through a query and match against a pre-set nut specification database. The nut specification database stores a comparison table of different nut specifications, corresponding weight reference intervals, and oiling control information. The nut specification database is retrieved through pre-input.

[0033] Step S105: When the weight detection value falls within the weight reference interval, the preset oiling pump 5 is controlled to start based on the oiling control information to oil the ball nut.

[0034] Among them, when the weight detection value falls into the weight reference range, it means that the ball nut has been placed in the preset oiling device. Therefore, the oiling control information is used to control the oiling pump 5 to start, thereby pumping the lubricating oil from the oil tank 2 to the oil spray head 4 to automatically oil the ball nut, so that the oiling method and amount of each ball nut are consistent, thereby improving the overall product quality of the ball nut and automatically detecting the oiling condition.

[0035] exist Figure 1After step S105, in order to further ensure the rationality of the oiling pump 5 that is controlled to start running based on the oiling control information to oil the ball nut, it is necessary to perform further separate analysis and calculation on the oiling pump 5 that is controlled to start running based on the oiling control information to oil the ball nut. Figure 2 The steps shown are explained in detail.

[0036] Reference Figure 2 The steps after controlling the preset oiling pump 5 to start running to oil the ball nut based on the oiling control information include the following steps: Step S200: Retrieve the oiling weight value based on the oiling control information.

[0037] Among them, the oiling control information includes the oiling weight value, which refers to the weight value required for oiling the ball nut of the corresponding specifications under normal circumstances. The oiling weight value is retrieved through the oiling control information for subsequent use.

[0038] Step S201: Calculate the weight change value based on the weight detection values before and after oiling.

[0039] Among them, the weight change value refers to the change in weight detected by the placement table 1 before and after oiling. The difference between the weight detection values before and after oiling is calculated and the calculated difference is used as the weight change value for subsequent use.

[0040] Step S202: Determine whether the weight change value is consistent with the oiling weight value. If yes, proceed to step S203; if not, proceed to step S204.

[0041] The consistency between the weight change value and the oiling weight value is determined to determine whether there is any abnormality in the oiling.

[0042] Step S203: controlling a preset clamping device to clamp the ball nut and place it at a preset quality inspection station.

[0043] The quality inspection station is used to clamp the oiled ball nut and test its quality. When the weight change matches the oiled weight, the ball nut is properly oiled. The clamping device then clamps the ball nut and places it on the pre-set quality inspection station, facilitating subsequent oiling quality testing.

[0044] Step S204: Calculate the difference between the weight change value and the oiling weight value and use it as the weight deviation value.

[0045] Among them, the weight deviation value refers to the deviation value corresponding to the deviation in the oiling quality. When the weight change value is inconsistent with the oiling weight value, it means that there is an abnormality in the oiling at this time. Therefore, the difference between the weight change value and the oiling weight value is calculated and used as the weight deviation value for subsequent use.

[0046] Step S205: obtaining a preset liquid level detection value in the oil storage tank 2.

[0047] The liquid level detection value refers to the detection value corresponding to the height of the lubricating oil level stored in the oil storage tank 2 , and the liquid level detection value is obtained by detecting a liquid level sensor preset in the oil storage tank 2 .

[0048] Step S206: Calculate the liquid level change value based on the liquid level detection values before and after oiling.

[0049] Among them, the liquid level change value refers to the change in the liquid level height of the lubricating oil in the oil storage tank 2 before and after oiling. The difference between the liquid level detection values before and after oiling is calculated, and the calculated difference is used as the liquid level change value for convenience of subsequent use.

[0050] Step S207: determining the oiling warning information according to the liquid level change value and the weight deviation value, and outputting the oiling warning information to the terminal held by the manager.

[0051] The lubrication warning information refers to warning information used to warn of lubrication anomalies. The administrator's terminal refers to a terminal that can receive this information. The administrator's terminal can be a mobile phone or computer. The lubrication warning information is determined by analyzing the liquid level change and weight deviation values, and is output to the administrator's terminal. This allows the administrator to promptly identify and address any lubrication anomalies, thereby improving the overall quality of subsequent ball nut lubrication. The specific steps for determining the lubrication warning information are described in steps S600 to S605.

[0052] exist Figure 2 After step S203, in order to further ensure the rationality of the process of controlling the preset clamping device to clamp the ball nut and place it in the preset quality inspection station, it is necessary to perform further separate analysis and calculation on the process of controlling the preset clamping device to clamp the ball nut and place it in the preset quality inspection station. Figure 3 The steps shown are explained in detail.

[0053] Reference Figure 3 The steps after controlling the preset clamping device to clamp the ball nut and place it in the preset quality inspection station include the following steps: Step S300: Obtaining a clamping pressure value of a preset quality inspection station.

[0054] Among them, the clamping pressure value refers to the clamping force corresponding to clamping the ball nut and performing oiling quality inspection in the quality inspection station. The clamping pressure value is detected and obtained through a pressure sensor preset in the quality inspection station.

[0055] Step S301: Determine the pressure reference range and rotation speed value according to the nut specification information.

[0056] Among them, the pressure reference range and rotation speed value refer to the clamping force reference range corresponding to the specifications of the ball nut when clamped under normal circumstances, and the rotation speed value refers to the rotation speed value corresponding to the oiling quality test of the nut clamping rotation of the specifications of the ball nut.

[0057] Different nut specifications correspond to different pressure reference intervals and rotational speed values. These pressure reference intervals and rotational speed values are retrieved by querying and matching a preset nut specification database. The nut specification database stores a comparison table of different nut specifications, corresponding pressure reference intervals, and rotational speed values. The nut specification database is retrieved by pre-entering the database.

[0058] Step S302: When the clamping pressure value is within a preset pressure reference interval, the preset quality inspection station is controlled based on the rotation speed value to rotate the ball nut and obtain sound detection information and vibration detection information.

[0059] The sound detection information refers to the sound information generated when the ball nut rotates during the oiling quality inspection, and the vibration detection information refers to the vibration information generated when the ball nut rotates during the oiling quality inspection. The sound detection information is detected and acquired by the sound detection device pre-installed at the quality inspection station. The vibration detection information is detected and acquired by the vibration detection device pre-installed at the quality inspection station.

[0060] When the clamping pressure value is within the preset pressure reference range, it indicates that the ball nut is clamped. Therefore, the ball nut is rotated at the rotation speed value by controlling the quality inspection station, and the sound detection information and vibration detection information are obtained in real time for subsequent use.

[0061] Step S303: Determine sound result information according to the sound detection information and preset sound reference information.

[0062] The sound reference information refers to the sound produced when the ball nut is properly lubricated. This sound reference information is obtained through pre-input. The sound result information refers to the comparison result between the sound produced after lubricating the ball nut and the sound produced under normal conditions. The sound detection information is compared with the preset sound reference information, and the comparison result is used as the sound result information for subsequent use.

[0063] Step S304: Determine vibration result information according to the vibration detection information and preset vibration reference information.

[0064] The vibration baseline information refers to the vibration information generated when the ball nut is properly lubricated. This vibration baseline information is obtained through pre-input. The vibration result information is the comparison result between the vibration generated after the ball nut is lubricated and the vibration under normal conditions. The vibration detection information is compared with the preset vibration baseline information and the comparison result is used as the vibration result information for subsequent use.

[0065] Step S305: Determine the quality inspection result information according to the sound result information and the vibration result information, and output the quality inspection result information to the terminal held by the administrator.

[0066] The quality inspection result information refers to the quality result information corresponding to the ball nut oiling test. The quality inspection result information is determined by analyzing the sound result information and the vibration result information. The quality inspection result information is then output to the terminal held by the administrator, allowing the administrator to promptly understand the ball nut oiling quality. The specific steps for determining the quality inspection result information are shown in steps S400 to S404.

[0067] exist Figure 3 In step S305, in order to further ensure the rationality of the quality test result information, it is necessary to further analyze and calculate the quality test result information separately, specifically by Figure 4 The steps shown are explained in detail.

[0068] Reference Figure 4 , the method for determining the quality inspection result information includes the following steps: Step S400: Determine whether the sound result information and the vibration result information are both consistent results. If yes, execute step S401; if not, execute step S402.

[0069] Here, whether the sound result information and the vibration result information are consistent is judged, thereby judging whether the oiling quality of the ball nut meets the requirements.

[0070] Step S401: Output the preset quality qualified result information as the quality inspection result information.

[0071] The "qualified quality result information" indicates that the ball nut's oiling quality has met the required quality. This qualified quality result information is obtained through pre-input. When the sound result information and the vibration result information are consistent, it indicates that the ball nut's oiling quality has met the required quality. Therefore, the preset qualified quality result information is output as the quality inspection result information, thereby improving the accuracy of the obtained quality inspection result information.

[0072] Step S402: Based on the sound result information and the vibration result information, the inconsistent results are used as result difference information.

[0073] Among them, the result difference information refers to the number, type, specific deviation, deviation position and other parameter information corresponding to the differences that exist when the oiling quality of the ball nut does not meet the requirements. When the sound result information and the vibration result information are not both consistent results, it means that the oiling quality of the ball nut does not meet the requirements at this time. Therefore, by analyzing the sound result information and the vibration result information, the information corresponding to the inconsistent results in the sound result information and the vibration result information is used as the result difference information for subsequent use.

[0074] Step S403: Retrieve difference values, difference type information, and difference parameter values based on the result difference information.

[0075] The result difference information includes the difference values, difference type information, and difference parameter values. The difference values refer to the values corresponding to the difference when the ball nut's oiling quality does not meet the requirements. The difference type information refers to the type information corresponding to the difference when the ball nut's oiling quality does not meet the requirements. The difference parameter value refers to the specific parameter value corresponding to the difference when the ball nut's oiling quality does not meet the requirements. The difference values, difference type information, and difference parameter values can be retrieved through the result difference information for subsequent use.

[0076] Step S404: When the difference value is one, determining single-category deviation result information according to the difference category information and the difference parameter value, and using the single-category deviation result information as the quality detection result information.

[0077] Among them, the single-category deviation result information refers to the result information corresponding to the deviation of a single category. When the difference value is one, it means that there is only one abnormality in the sound or vibration at this time. Therefore, the preset single-category result database is queried through the difference category information and the difference parameter value to obtain the single-category deviation result information, and the single-category deviation result information is used as the quality inspection result information, thereby improving the accuracy of the obtained quality inspection result information.

[0078] Different difference type information and difference parameter values correspond to different single type deviation result information. The single type result database stores a comparison table of each different difference parameter value in different difference type information and the corresponding single type deviation result information. The single type result database is obtained after pre-input.

[0079] exist Figure 4 After step S403, in order to further ensure the rationality of the difference values, difference type information and difference parameter values retrieved based on the result difference information, it is necessary to perform further separate analysis and calculation on the difference values, difference type information and difference parameter values retrieved based on the result difference information. Figure 5 The steps shown are explained in detail.

[0080] Reference Figure 5 The steps after retrieving the difference values, difference type information and difference parameter values based on the result difference information include the following steps: Step S500: When the difference value is not one, retrieve the difference position points based on the result difference information.

[0081] The result difference information includes the difference location points, which correspond to the differences that occur when the ball nut's oiling quality does not meet the requirements. If the difference value is different from 1, it indicates that there is an abnormality in either sound or vibration. Therefore, the difference location points can be retrieved through the result difference information for subsequent use.

[0082] Step S501: determining single position deviation result information according to the difference position points and the difference parameter values.

[0083] The single-position deviation result information refers to the result information corresponding to a deviation at a single position in the ball nut. This single-position deviation result information is obtained by querying a preset single-position result database using the differential position points and differential parameter values, facilitating subsequent use. Different differential position points and differential parameter values correspond to different single-position deviation result information. The single-position result database pre-stores a comparison table of different differential position points, differential parameter values, and corresponding single-position deviation result information. The single-position result database is obtained by pre-entering the data.

[0084] Step S502: Determine whether the difference position points are consistent. If yes, go to step S503; if no, go to step S504.

[0085] Here, by judging whether the difference position points are consistent, it is judged whether the position points corresponding to the deviations between the sound and the vibration interfere with each other.

[0086] Step S503: using the single position deviation result information as quality detection result information.

[0087] Among them, when the difference position points are consistent, it means that the sound deviation and the vibration deviation are generated at the same position, so the single position deviation result information is used as the quality detection result information.

[0088] Step S504: Calculate the distance between the different position points and use it as the difference distance value.

[0089] Among them, the difference distance value refers to the distance value between the position corresponding to the sound deviation and the position corresponding to the vibration deviation. When the difference position points are inconsistent, it means that the sound deviation and the vibration deviation are not generated at the same position. Therefore, the distance between the difference position point where the sound deviation exists and the difference position point where the vibration deviation exists is calculated and used as the difference distance value for subsequent use.

[0090] Step S505: Determine the difference reference distance value according to the nut specification information.

[0091] The differential reference distance value refers to the reference distance between the allowable sound and vibration deviation positions of the ball nut specification under normal circumstances.

[0102] The oil addition warning information is a warning message indicating the need to add lubricant to the oil tank. This information is obtained through pre-input. When the liquid level change value matches a preset baseline change value, indicating that the lubricant in oil tank 2 is insufficient, the preset oil addition warning message is output as the re-lubrication warning message, thereby improving the accuracy of the obtained re-lubrication warning message.

[0104] Among them, the liquid level deviation value refers to the deviation value corresponding to the abnormal change of the liquid level. When the liquid level change value is inconsistent with the preset reference change value, it means that the lubricating fluid in the oil storage tank 2 has an abnormal change.

[0119] The deviation distance impact value refers to the degree of influence of the deviation distance on brightness. Different illumination-reception deviation distance values correspond to different deviation distance impact values. The deviation distance impact value is obtained by querying a database that stores a comparison table of different illumination-reception deviation distance values and corresponding deviation distance impact values. This database is obtained through pre-input. Determining the deviation distance impact value by querying the illumination-reception deviation distance value facilitates subsequent use.

[0121] The illumination brightness adjustment value refers to the brightness value after adjusting the brightness after passing through the oil storage tank 2.

[0125] The brightness deviation impact value refers to the degree of impact of brightness deviation on the reference range of the liquid level. Different brightness deviation values correspond to different brightness deviation impact values. The brightness deviation impact value is obtained by querying a database that stores a comparison table of different brightness deviation values and their corresponding brightness deviation impact values. This database is obtained through pre-input. Determining the brightness deviation impact value through the brightness deviation value query facilitates subsequent use.

[0131] Step S801: determining the oil deterioration warning information corresponding to the brightness deviation value according to the corresponding relationship between the brightness deviation value and the preset oil deterioration warning information, and using the oil deterioration warning information as the oil abnormality warning information.

[0132] Oil deterioration warning information refers to warning information about oil deterioration. Different brightness deviation values correspond to different oil deterioration warning information. This information is retrieved from a database that stores a comparison table of different brightness deviation values and corresponding oil deterioration warning information. This database is retrieved through pre-input. When the liquid level deviation value falls within the oil reference deviation range, it indicates that the oil has deteriorated. Therefore, the oil deterioration warning information is determined by querying the brightness deviation value and used as oil abnormality warning information, thereby improving the accuracy of the obtained oil abnormality warning information.

[0133] Step S802: Calculate the difference between the liquid level deviation value and the oil reference deviation interval and use it as the abnormal liquid level deviation value.

[0134] Among them, the abnormal liquid level deviation value refers to the deviation value corresponding to the abnormal deviation of the liquid level. When the liquid level deviation value does not fall into the oil reference deviation interval, it means that the oil has not deteriorated at this time. Therefore, the difference between the liquid level deviation value and the oil reference deviation interval is calculated and used as the abnormal liquid level deviation value for subsequent use.
