Description

Technical Field

[0001] The invention belongs to the technical field of spray coating, and in particular relates to a vehicle painting operation line production management system. Background Art

[0002] Common railway freight cars include open wagons, flat wagons, and covered wagons. Freight cars usually have patterns and numbers sprayed on the body to identify the vehicle. For example, P stands for covered wagons, and common models include P62, P64, P70, etc. C stands for open wagons, and common models include C62K, C70, C80, etc. X stands for container-specific flat wagons, and common models include X70, X6K, etc.

[0003] Before railway freight cars leave the factory, patterns and numbers are sprayed on them to identify the vehicles. During the use of railway freight cars, the sprayed patterns and numbers will also be worn. After wear, the marks will be cleaned and re-sprayed. Although there are corresponding spraying robots for the traditional spraying of patterns and numbers on railway freight cars, manual assistance is still required. Personnel input the patterns to be sprayed and the spraying positions, and manually control the spraying robots. There will be multiple vehicles spraying at the same time on the production line. When there is a shortage of manpower, it will cause a problem of reduced production efficiency. Summary of the invention

[0006] An information collection module is provided at the entrance of the vehicle track, and the information collection module is used to collect vehicle information through an information tag provided on the vehicle and send the vehicle information to a processing system;

[0007] The processing system includes an information management module;

[0008] An information management module is used to generate processing information according to vehicle information, wherein the processing information includes a processing location and processing items, and send the processing information to a cleaning and painting system;

[0009] The RGV cart is used to drive the robot to move to the processing position. The robot is used to perform cleaning and painting according to the processing items. When the processing item is cleaning, the marks on the vehicle are cleaned by an automatic paint spray gun. When the processing item is painting, the marks are painted on the vehicle by an automatic spray head.

[0010] The principle and advantage of the present invention are: an RGV trolley track and a vehicle track are set, the RGV trolley runs on the RGV trolley track, and the vehicle enters the vehicle track when entering the warehouse. When entering the vehicle track, the vehicle information is collected through the information collection module set at the entrance of the vehicle track. After the vehicle information is collected, it can be determined whether the vehicle entering the track needs to be cleaned or sprayed, or both. The processing system generates processing information based on the vehicle information and sends the processing information to the cleaning and painting system. After receiving the processing information, the cleaning and painting system controls the RGV trolley to move to the set position according to the processing information, and controls the robot to spray according to the set marking pattern and marking position. Or clean the existing marks on the vehicle according to the set marking position.

[0019] The robot is used to perform cleaning according to the current marking position, or to perform painting according to the new marking pattern and the new marking position.

[0020] After obtaining the vehicle information, if there is already a mark on the vehicle, the current mark position is obtained according to the record of the mark on the vehicle in the vehicle information. And according to the vehicle type, a new mark pattern and new mark position are generated. The cleaning and painting system first uses an automatic paint spray gun to spray paint on the old mark to clean the old mark. Then the new mark is painted on the car body.

[0021] Furthermore, the cleaning and coating system:

[0022] It is also used to, when processing information of multiple vehicles is identified and the processing items include cleaning processing and painting processing, clean the vehicles in sequence according to the processing sequence, and then paint the vehicles in sequence according to the processing order.

[0023] When there are multiple vehicles entering the track for processing at the same time, each vehicle is cleaned first, and after all vehicles are cleaned, each vehicle is painted in turn. In this way, after the original marking is sprayed and cleaned, the other vehicles can be cleaned while waiting for the paint to dry.

[0024] Furthermore, charging piles are provided at both ends of the RGV trolley track, there are at least two RGV trolleys, and the processing system further includes a charging management module;

[0025] The charging management module is used to obtain the power of the RGV car. When the power of the RGV car is lower than the preset power threshold, the RGV car is controlled to go to the charging pile for charging;

[0026] The information management module is also used when an RGV car is charging at a charging pile. If multiple vehicles enter the vehicle track, they are sorted starting from the vehicle farthest from the current charging pile.

[0027] Charging piles are set at both ends of the RGV car, and both ends can be charged. The power of the RGV car is obtained. When the power of the RGV car is lower than the preset power threshold, the RGV car is controlled to go to any charging pile for charging. Setting charging piles at both ends can reduce the number of times the RGV car moves through the factory and reduce interference with the working environment. When one RGV car is charging, the other RGV car starts running from the end far away from the current charging end.

[0028] Further, the charging management module includes a power difference module and a power consumption analysis module;

[0029] The power difference module is used to calculate the power difference between the two RGVs according to the power of the two RGVs;

[0030] The power consumption analysis module is used to identify the power consumption of the RGV in a process based on historical data;

[0031] The charging management module is also used to control the RGV car with lower power to go to the charging pile for charging when the power difference of the RGV car is higher than the power consumption of the RGV car processed at one time.

[0032] The power difference between the two cars is identified. When the power difference between the two cars is higher than the power consumption of the RGV car that is processed at one time, the RGV car with lower power is controlled to go to the charging pile for charging. At this time, the RGV car with higher power can also complete the task of processing at one time alone. Therefore, the RGV car with lower power is controlled to go to charge at this time to ensure that the two subsequent RGV cars can work at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
