Description

Technical Field

[0001] The present invention relates to the technical field of vehicle production and processing, and in particular to a production line processing error prevention control method, system, storage medium and electronic equipment. Background Art

[0002] With the progress and development of society, the production model of the automobile industry is also gradually changing. In the last century, the demand for automobiles in the market was large and the varieties were relatively single, so automobile production mainly adopted the fixed production line model. Nowadays, as people's consumption of automobiles has gradually changed from "travel needs" to "personalized consumption", the types and models of automobiles are also constantly being subdivided. The result is that compared with the past, automobile manufacturers need to switch production plans for more models of automobiles more frequently during the production process. Therefore, it is particularly important to formulate production plans for different orders in the automobile production process.

[0003] At present, there are three main production modes in vehicle manufacturing, namely: processing workshop mode, batch production mode and mixed line production mode. Among them, mixed line production is the mainstream production mode of existing automobile manufacturers. Mixed line production mode: It is to manufacture different models of products on the same production line. Based on the batch production mode, this mode adopts a more universal production platform. The positioning points of the frame can be shared among multiple models to be produced, and the production method of the production equipment is more flexible and more flexible. There is no need to stop the production line to replace the scheduling processing equipment when switching between different models of production. Instead, it can accurately identify the model product to which the current parts or components to be processed belong, and carry out the processing and production of the current process according to the corresponding pre-established procedures. At the same time, in terms of tool allocation, ensure that the tools are switched as flexibly as possible when producing parts of different models, without spending a lot of time on switching tooling tools.

[0004] Among them, when the mixed assembly line produces models, due to the inconsistency of the model design, although the screws at the same station are the same, the torque of the screws at different models is inconsistent. Employees often use the wrong torque to tighten, resulting in batch quality accidents. In the prior art, for the situation where the same screws at the same station have different torques for different models, the current solution is to arrange the screws and the corresponding tightening tools at different stations, which requires additional personnel, tools and venues and cannot be completely error-proof.

[0040] Embodiment 1

[0041] See also Figure 1 , shown is a production line processing error prevention control method in the first embodiment of the present invention, and the method specifically includes steps S01 to S03.

[0042] S01, setting a sensor device at a preset position of a production line, and determining distribution information of the sensor device, then receiving sensor information sent by the sensor device, and determining position information of the vehicle according to the distribution information and the sensor information;

[0043] Specifically, by setting up sensor equipment at specific locations, the real-time position information of each vehicle to be processed can be obtained, and then the type of vehicle to be processed at each workstation at different time points can be determined. According to the vehicle type, the processing parameters required for the vehicle can be determined to avoid errors.

[0044] S02, obtaining source queue information, determining process information and corresponding torque parameter information according to the source queue information and the position information, and then determining torque information of each workstation at different time points according to the process information and the torque parameter information;

[0045] Specifically, the sequence information of the processing vehicles at each workstation and the process parameter information corresponding to different vehicles are determined through the source team information. Then, whether the vehicle processing sequence is accurate is determined based on the vehicle position information. When it is accurate, the processing parameter information at each time, that is, the torque information, is determined in sequence according to the sequence information. When it is inaccurate, new sequence information is determined according to the position information, and then the torque information at each time point is determined in sequence according to the new sequence information and the new process parameters.

[0046] S03, sending the torque information to the workstation computer of each workstation, so that the workstation computer determines the torsion angle of the torsion tool according to the torque information, and then enables the worker to tighten the screws of the vehicle according to the torque angle;

[0047] Specifically, after determining the torque information of each workstation at different time points, the torque information is sent to the workstation computer, so that workers can tighten the screws according to the information on the workstation computer, achieving an error-proofing effect without the need to set up additional workstations and workers.

[0048] In addition, after this step, the method further includes receiving the orientation angle information of the twisting tool, and judging whether the employee is tightening the screws of the target vehicle with the twisting tool according to the orientation angle information, the twisting information and the vehicle position information;

[0049] If an employee uses the torque tool to tighten the screws of the target vehicle, the drive information is sent to the workstation computer, so that the workstation computer sends the torque angle and the drive information to the torque tool, so that the torque tool is unlocked, and the worker can operate the torque tool to tighten the target screws;

[0050] If the employee fails to tighten the screws of the target vehicle with the torque tool, an error message is sent to the workstation computer, so that the workstation computer issues an error alarm through the sound transmission device, so that the worker adjusts the screw target aimed at by the torque tool according to the error alarm; the step of returning to execute the step of receiving the orientation angle information of the torque tool, and judging whether the employee has tightened the screws of the target vehicle with the torque tool according to the orientation angle information, the torque information and the vehicle position information.

[0051] Specifically, when workers tighten the screws of a vehicle, since there are many screws on the vehicle and the tightening torque required for screws of the same shape is different, it is necessary to determine the correct screw tightening object through the posture of the twisting tool, thereby achieving the effect of secondary error prevention. When the screw tightening object is correct, the twisting tool will be unlocked through instructions, allowing the worker to tighten the target screw.

[0052] In addition, if the employee uses the torque tool to tighten the screws of the target vehicle, the step includes receiving tightening information sent by the torque tool and judging whether the target screws are tightened correctly according to the tightening information;

[0053] If the target screw is tightened correctly, the completion information is sent to the transfer device and the workstation computer, so that the transfer device drives the vehicle to be transferred to the next workstation, and the workstation computer sends a gun locking information to the torque tool, so that the torque tool is locked;

[0054] If the target screw is not tightened correctly, a stop command is sent to each production line equipment to stop the production line, and an abnormal information is sent to the large screen display board in the workshop so that workers can judge whether it is tightened;

[0055] If the worker determines that the tightening is done, the worker receives the confirmation information, controls the production line to resume operation, and generates defect information and sends it to the inspection station computer, so that the worker at the inspection station can conduct multiple inspections and confirmations on the tightening condition;

[0056] If the worker determines that it is not tightened, he / she will receive an error message and send the error message to the maintenance worker so that the maintenance worker can check and maintain the system and equipment.

[0057] Specifically, although multi-step error prevention measures are taken to avoid errors in the torque of screw tightening, it is impossible to avoid the situation where the torsion tool itself fails. Therefore, it is necessary to obtain the situation of this torsion through an independent sensor device set on the torsion tool to determine whether the torsion angle is consistent with the preset torque angle. If they are consistent, continue to execute the predetermined steps. If they are inconsistent, manual judgment is required to ensure correct tightening. If they are tightened correctly, there is a problem with the sensor device or a program failure, and the vehicle is sent to the next process. If they are not tightened correctly, the equipment needs to be checked to determine the cause of the failure.

[0058] In addition, the orientation angle information, the corresponding torsion information and the vehicle position information are collected, the orientation angle information, the corresponding torsion information and the vehicle position information are summarized, and error-prone information is determined, so that workers can reduce the error frequency according to the error-prone information. Specifically, by collecting information on each orientation angle, the worker's error-prone situation is determined, so that the worker can make adjustments according to the error-prone situation, reduce the error frequency, and improve production efficiency.

[0059] In summary, the production line processing error prevention control method in the above embodiment of the present invention sets a sensing device at a preset position, determines the position information of the vehicle to be processed and assembled according to the distribution information of the sensing device and the sensing information of the sensing device, and determines the process parameters of each vehicle according to the position information and source queue information of the vehicle, thereby determining the process participation of each workstation and the vehicle at different time points, that is, determining the position distribution of the screws to be tightened corresponding to the processing vehicle at each workstation and at different time points, and the required tightening torque, that is, torque information, and sending the torque information to the workstation computer, so that the workers at the workstation perform the screw tightening process for the vehicles to be processed at different time points according to the torque information, thereby ensuring that the screw tightening torque of the vehicles corresponding to each time point and workstation is correct, thereby realizing error prevention control, avoiding the problems of mixed line production, and no additional workstations and staff are required, only the existing sensing equipment needs to be used to add error prevention steps, which greatly reduces the economic cost. Therefore, the present invention solves the problem that the production line processing error prevention control method in the prior art is not comprehensive enough.
