Description

Technical Field

[0001] This application relates to the field of automobile manufacturing and assembly technology, specifically to a method, apparatus, equipment, and computer-readable storage medium for filling transmission fluid. Background Technology

[0002] In the assembly process of automotive powertrains, adding transmission fluid is one of the key steps. The accuracy of the filling, the correct type of fluid, and the reliability of the filling process directly affect the service life of the transmission, shift quality, and overall vehicle comfort. Missing, incorrect, or insufficient filling can lead to poor transmission lubrication, accelerated wear, or even complete failure. Furthermore, these defects are often subtle and difficult to detect before the final assembly line rolls off the production line.

[0003] Currently, most transmission fluid filling processes utilize a transmission fluid metering machine. This method controls the start and stop of filling via a device logic controller, with a flow meter measuring the filling volume in real time, and automatically stopping once the set value is reached.

[0004] However, existing technologies often rely on a single flow meter for measurement. When the flow meter experiences zero drift, impeller jamming, idling, sensor aging, or calibration failure, the equipment may still display a normal filling volume, but in reality, no oil may be dispensed or the oil may be insufficient. Such hidden faults cannot be detected in time.

[0005] Furthermore, existing technologies rely excessively on employee skills and manual operation, lacking pre-filling verification procedures. As the types of oils increase, although the equipment can select the appropriate vehicle program based on process parameters, it places high demands on the parameter maintenance skills and manual operation of process personnel. Moreover, a single error is difficult to detect, which can lead to serious quality problems.

[0006] Therefore, how to develop a transmission fluid filling method that can break free from dependence on single-point equipment stability, personnel skills, and human operation, and promptly detect errors that occur during the production process, has become a technical problem that urgently needs to be solved in this field.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0022] In a first aspect, embodiments of this application provide a method for adding transmission fluid.

[0023] In one embodiment, reference is made to Figure 1 , Figure 1 This is a schematic flowchart of the first embodiment of the transmission fluid filling method of this application. Figure 1 As shown, the methods for adding transmission fluid include: Step S1: Based on the vehicle model information of the target vehicle, determine the refueling acceptance indicators corresponding to the target vehicle. The refueling acceptance indicators include the target oil grade and the target refueling volume. This embodiment primarily addresses multi-vehicle production environments in assembly line scenarios. Since the transmission fluid filling process parameters differ for each vehicle model, manually verifying these parameters is prone to errors due to the individual's skill level. To address this, this embodiment pre-stores the target vehicle's VIN code, its model number, and the corresponding filling procedure's acceptance criteria in the filling equipment. Upon receiving a target vehicle, the VIN code is first identified to obtain the vehicle model information. Based on this model information, the filling process's acceptance criteria are determined, eliminating the need for manual judgment and thus avoiding errors caused by human error.

[0024] Furthermore, in this embodiment, the filling acceptance criteria include the target oil grade and the target filling amount, wherein the target oil grade is the oil grade corresponding to the transmission fluid required by the transmission of the target vehicle, and the target filling amount is the volume of transmission fluid in the transmission of the target vehicle operating under optimal conditions.

[0025] Step S2: Verify the refueling preparation work based on the refueling acceptance indicators to obtain the verification result of the refueling preparation work; In one embodiment, the filling equipment is further equipped with a process parameter and BOM data comparison and verification unit, whereby the BOM data is a bill of materials required to perform the filling procedure. For each vehicle model and each transmission model, the BOM data specifies the target oil grade and target filling volume. After determining the acceptance criteria, the filling equipment performs filling preparation work, including setting filling parameters and determining the volume of transmission fluid to be filled, and confirming the actual oil grade of the transmission fluid to be filled based on the information on the transmission fluid container. After the filling equipment completes the filling preparation work, the process parameter and BOM data comparison and verification unit verifies the filling preparation work. The verification includes confirming whether the actual oil grade of the transmission fluid to be filled in the filling equipment matches the target oil grade, and whether the actual volume of the transmission fluid to be filled in the filling equipment matches the target filling volume. When the filling parameters meet the filling acceptance criteria, the system displays "qualified"; when the two do not match, the system displays "unqualified".

[0026] In one embodiment, the refueling device further includes an oil replenishment scanning and verification unit. When the transmission oil volume in the refueling equipment is insufficient, the operator will be reminded to replace the oil drum for replenishment. When the operator replenishes the oil, the barcode or QR code of the oil drum to be replaced is scanned using a scanning device. The system automatically identifies the oil type number and compares it with the oil type required by the current refueling equipment. When the comparison results match, the operator is allowed to perform the replenishment operation. When the results do not match, the system will issue an alarm and lock the replenishment valve.

[0027] Step S3: Control the transmission fluid filling process based on the verification results of the filling preparation work; In this embodiment, if the verification result of the refueling preparation work is qualified, the refueling procedure is executed on the target vehicle based on the refueling acceptance indicators; If the verification result of the refueling preparation work is unqualified, an alarm will be issued. After the operator makes corrections, the refueling preparation work of this refueling procedure will be re-executed based on the refueling acceptance indicators.

[0028] Step S4: Measure the real-time flow generated during the filling process using two preset flow meters, and monitor the filling process based on the consistency between the measurement results of the two flow meters.

[0029] In this embodiment, the refueling device is configured with two independent flow meters in parallel to measure the real-time flow generated during the refueling process. The consistency between the measurement results collected by the two flow meters is used to determine whether there is a serious error between the two flow meters. When the flow readings of the two flow meters are consistent, it means that both flow meters are in normal working condition. If either flow meter has a fault such as zero drift, impeller jamming, idling, or aging, the readings of the two flow meters will show a significant deviation, indicating that there may be a serious error in the currently displayed flow reading, that is, there is an abnormal phenomenon in the current refueling process.

[0030] like Figure 2 As shown, specifically, in this embodiment, step S4 further includes: Step S401: Calculate the flow difference between the first flow rate corresponding to one of the flow meters and the second flow rate corresponding to the other flow meter; It is understandable that due to unavoidable errors in the operation of the refueling equipment, the readings of the two flow meters cannot be absolutely consistent. In this case, this embodiment analyzes the flow difference between the two flow meter readings to determine whether there is an abnormality in the refueling process.

[0031] Step S402: If the flow rate difference is greater than or equal to the flow rate threshold, there is an anomaly in the refueling process; In this embodiment, the flow difference is used as the logical judgment value to determine whether there is an anomaly during the refilling process. The relationship between the flow difference and the flow threshold is the basis for judging whether there is an anomaly during the refilling process. When the flow difference is greater than or equal to the flow threshold, it indicates that the deviation between the two flow meters has exceeded the normal error range, at least one flow meter has malfunctioned, the current flow reading is determined to be unreliable, and the current refilling process is determined to be abnormal. It should be noted that the specific value of the flow threshold can be determined according to the type, model, and other relevant parameters of the flow meter, and is not limited here.

[0032] Step S403: If the flow difference is less than the flow threshold, there is no abnormality in the refueling process.

[0033] In this embodiment, if the flow difference between the two flow meters is less than the flow threshold, it means that the flow deviation between the two flow meters is within the normal error range and will not affect the quality of this filling. Therefore, it is determined that there is no abnormality in the filling process.

[0034] Furthermore, in one embodiment, the method further includes: Obtain the actual duration of the betting process; The duration difference between the actual refueling duration and the target refueling duration is obtained based on the actual refueling duration and the target refueling duration; If the duration difference is greater than or equal to the duration threshold, the injection process is abnormal. If the time difference is less than the time threshold, there is no abnormality in the injection process.

[0035] For example, in this embodiment, when the refueling device starts executing the refueling procedure, the time monitoring unit in the refueling device will time the current refueling procedure to obtain the actual refueling duration in real time. By analyzing the actual refueling duration, the current operating status of the refueling device can be confirmed.

[0036] In this embodiment, the refueling acceptance criteria also include the target refueling time required for the refueling procedure. The refueling equipment is also equipped with a refueling monitoring unit, which is used to monitor the actual refueling time in real time, monitor the refueling process according to the target refueling time and the actual refueling time, and determine the working status of the refueling equipment.

[0037] It is understandable that due to structural differences, changes in operating conditions, and other objective factors among refueling equipment, it is impossible to ensure that the actual refueling time is completely consistent with the target refueling time during the actual refueling process. That is, there will be a certain deviation between the target refueling time and the actual refueling time, i.e., the duration difference. By analyzing the duration difference, the current working status of the refueling equipment can be confirmed.

[0038] In this embodiment, the duration threshold is used to determine whether the refueling equipment is in a normal state. By using whether the duration difference is greater than the duration threshold as the criterion for determining whether the refueling equipment is malfunctioning, the operating condition of the refueling equipment can be judged. When the duration difference exceeds the duration threshold, it indicates that the refueling equipment may have problems such as pipeline blockage, abnormal oil pressure, decreased oil pump efficiency, or insufficient oil in the oil drum, that is, there is an abnormal phenomenon in the current refueling process.

[0039] It should be noted that the specific value of the duration threshold can be determined based on the type, model, and other relevant parameters of the refueling equipment, and is not limited here.

[0040] In this embodiment, when the time difference is less than the time threshold, it indicates that the current equipment is operating well, the time difference is within the normal error range, and will not affect the quality of this refueling. Therefore, it is determined that there is no abnormality in the refueling process.

[0041] Furthermore, in one embodiment, the method further includes: If any abnormality occurs during the refueling process, the refueling will be terminated. If there are no abnormalities in the betting process, continue betting until the betting is completed.

[0042] In this embodiment, the dispensing device monitors any abnormalities that occur during the dispensing process. If an abnormality is detected during the dispensing process, the device will intervene in the currently executing dispensing program to ensure the quality of the final dispensing.

[0043] If the refueling equipment detects an abnormality during the refueling process, it will immediately terminate the currently executing refueling procedure and promptly output fault information for operators to screen and handle, preventing further impact.

[0044] If the refueling equipment does not detect any abnormalities during the refueling process, it is determined that the current refueling process is normal and will not affect the final refueling quality. The refueling equipment is then controlled to complete the refueling procedure normally.

[0045] Furthermore, in one embodiment, the refueling acceptance criteria also include the target oil quality, and the method further includes: Obtain the refueling parameters after refueling is completed, including the actual oil quality and the actual refueling volume; The filling parameters after filling are verified based on the filling acceptance criteria to obtain the filling result; If the verification result of the actual amount added is qualified, and the inspection result of the actual oil quality is qualified, then the result of this addition is qualified. If either the verification result of the actual amount added or the inspection result of the actual oil quality is unqualified, then the result of this addition is unqualified.

[0046] As an example, in this embodiment, after the filling is completed, the filling device will also collect the filling parameters generated by the filling procedure. The filling parameters include the actual filling amount and the actual quality of the transmission fluid added to the target vehicle.

[0047] Specifically, during step S1, the target oil quality, including the target viscosity grade and target performance grade, can be determined by identifying the target oil grade. The filling equipment is also equipped with a data acquisition and testing module, which can use the residual transmission fluid in the filling equipment after the current filling as a sample to obtain the actual viscosity and actual performance grade of the actually filled transmission fluid, i.e., the actual oil quality.

[0048] Meanwhile, the refueling equipment can obtain the actual refueling volume based on the actual flow rate and actual refueling time measured during this refueling. Combining the verification results of the target oil quality against the actual oil quality and the verification results of the target refueling volume against the actual refueling volume, the verification result of this refueling can be obtained, ensuring that the target vehicle meets the off-line requirements.

[0049] In this embodiment, by pre-matching different vehicle models with corresponding refueling acceptance indicators, and upon receiving the target vehicle, confirming the matching refueling acceptance indicators based on the vehicle model information, this solves the technical problem in the prior art where the determination of refueling indicators relies on personnel maintenance skills. By verifying the results of the refueling preparation work based on the refueling acceptance indicators, and determining whether to execute the refueling process based on the verification results, this avoids the situation in the prior art where human error in the refueling preparation work leads to errors that affect the final refueling quality. Through the parallel design of two flow meters, based on the two... The readings of each flow meter are used to monitor the refueling process, enabling the identification of the current operating condition of the flow meter and solving the technical problem of relying on the stability of a single device at a single point in the existing technology. By monitoring the refueling process based on the refueling time and the target refueling time, the technical problem of not being able to accurately identify anomalies in the refueling process by monitoring the refueling process with only a single parameter in the existing technology is solved. The refueling acceptance index is used to verify the refueling parameters collected after refueling and confirm the refueling result, solving the technical problem of not being able to detect refueling quality problems caused by aging and errors of the refueling equipment in a timely manner in the existing technology.

[0050] In summary, the proposed solution pre-matches the target vehicle's model information with the filling acceptance criteria, and monitors the entire workflow from the filling preparation stage to the acceptance stage based on the filling acceptance criteria. Combined with the design of dual flow meters, it enables the data acquisition equipment to perform self-testing, thus eliminating the reliance on single-point stability of equipment, personnel skills, and human operation in existing technologies, and improving the yield rate of transmission oil filling.

[0053] Furthermore, in one embodiment, the monitoring module is also used to calculate the flow difference between a first flow rate corresponding to one of the flow meters and a second flow rate corresponding to the other flow meter; If the flow difference is greater than or equal to the flow threshold, there is an abnormality in the refueling process; If the flow difference is less than the flow threshold, there is no abnormality in the refueling process.

[0055] Furthermore, in one embodiment, the execution module is also used for If any abnormality occurs during the refueling process, the refueling will be terminated. If there are no abnormalities in the betting process, continue betting until the betting is completed.
