All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a flow chart of a production plan control method based on a coating shop according to an embodiment of the present invention is shown, where the production plan control method based on a coating shop includes:
step S1: acquiring a plurality of coating production plans sent by an MES system; each coating production plan comprises a vehicle type identification code and a production sequence number corresponding to the vehicle type identification code;
step S2: when a vehicle body is detected to reach an on-line work site of a painting workshop, a painting production plan is executed, and when all the painting production plans are detected to be executed and a preset work site of the painting workshop is detected to pass through, the MES system is requested to send a total production plan containing a plurality of vehicle type identification codes;
step S3: after receiving the total production plan sent by the MES system, updating the corresponding production sequence in the coating production plan according to the production sequences corresponding to the vehicle type identification codes in the total production plan, and generating an updated production plan;
step S4: and taking the updated production plan as a production plan corresponding to a offline working site of a coating workshop.
For step S1, in a preferred embodiment, a coating production plan sent by the MES system and including a vehicle type identifier and a production sequence number corresponding to the vehicle type identifier is obtained. The production sequence number may be a production sequence number corresponding to each process production flow in the coating workshop, and may not be a production sequence of a certain process, but may be a production sequence corresponding to each process.
It is understood that the coating production plan is a production plan suitable for the special requirements of coating production, and the on-line sequence of the coating shop body can be controlled according to the coating production plan; after the coating of the vehicle body is finished, the invention can restore the original main production plan through the interface of the MES system and the system of the invention so as to control the off-line sequence of the vehicle body in the coating workshop. Thereby simultaneously meeting the production special requirements of a coating workshop and the original production requirements of the whole company.
Before issuing the coating production plan, the invention can integrate the information of each vehicle body according to the original main production plan so as to finish sequencing the production sequence of each vehicle body and automatically generate the corresponding coating production plan meeting the special requirements of a coating workshop.
In a preferred embodiment, the generation of the painting production plan includes:
acquiring each initial coating production plan corresponding to each vehicle type identification code in the total production plan; wherein the initial paint production schedule includes any one or a combination of the following: an initial paint production plan for the non-test vehicle and an initial paint production plan for the test vehicle;
the initial paint production schedule for each of the non-test vehicles includes: vehicle type identification code, initial production sequence number, vehicle body color, vehicle body size and vehicle body assembly condition;
the initial paint production schedule for each of the test vehicles includes: vehicle type identification code, initial production sequence number, vehicle body color, vehicle body size, vehicle body assembly condition and test vehicle identification;
illustratively, each initial paint production plan may or may not include an initial paint production plan for a test vehicle, and the initial paint production plans for a test vehicle may differ from the initial paint production plans for a non-test vehicle in the presence of a test vehicle identifier.
It will be appreciated that the presence of the test car identification indicates that the corresponding car body needs to be lifted from a specific station without passing through the coating/bus delivery station, and therefore, the test car identification is not included in the production plan of the company MES system, and the identification and operation still need to be performed manually in the prior art, and the automatic generation and automatic execution of the coating production plan of the present invention can enable the control equipment in the coating shop to perform automatic identification and lifting according to the test car identification.
In the generation of the coating production plan of the present invention, the initial production sequence numbers in each initial coating production plan may be updated according to the test vehicle logo, the vehicle body color, the vehicle body size, and the vehicle body assembly condition, to generate the coating production plan.
Specifically, firstly, sorting all initial coating production plans for one time according to the assembly condition of the vehicle body;
when the sorting is carried out for one time, generating a plan for initial coating, wherein the assembly condition of the vehicle body is not completed, and arranging the plan before the production plan for initial coating, wherein the assembly condition of the vehicle body is completed; it will be appreciated that the vehicle body assembly may be: whether roof assembly is complete or whether other vehicle body components are complete; for the type of vehicle body, the vehicle body can be sent to a final assembly workshop after being coated in a coating workshop, so that when the vehicle body is sequenced for one time, an initial coating generation plan which is not assembled is sequenced in advance, the type of vehicle body can be coated first, and when other vehicle bodies are coated, the vehicle can be assembled for enough time and then sent to the next workshop, therefore, the automatic sequencing method can reduce the time of the whole coating workshop and improve the production efficiency of the coating workshop;
further, according to the colors of the vehicle bodies, the assembly conditions of the vehicle bodies are secondarily ordered as an initial coating production plan after the assembly is completed;
when the secondary sorting is performed, taking the colors of the vehicle bodies, which are corresponding to the initial painting generation plans arranged at the tail end in the initial painting generation plans which are not assembled, as target colors when the primary sorting is completed; it can be understood that the invention can acquire the colors of the vehicle body corresponding to the initial painting generation plan arranged at the tail according to the first sorting, and then arrange the same colors at the first position during the second sorting, so that the color changing times and the color changing time of the painting robot can be reduced, and the efficiency of the painting process of the painting workshop can be further improved;
specifically, judging whether an initial coating production plan with the consistent vehicle body color and the target color exists in the assembled initial coating production plan or not according to the assembly condition of each vehicle body;
if the initial coating production plans exist, updating the sequence of the initial coating production plans with the consistent vehicle body colors and the target colors to the first position of secondary sequencing, sequencing at least two remaining initial coating production plans with the same vehicle body colors from large to small according to the number of the same vehicle body colors, and sequencing the remaining initial coating production plans before the initial coating production plans without the same vehicle body colors;
if the initial painting production plans of the same vehicle body color do not exist, sequencing at least two initial painting production plans of the same vehicle body color from large to small, and sequencing the initial painting production plans of the same vehicle body color before the initial painting production plans of the same vehicle body color;
according to the invention, when the second sorting is performed, the plan corresponding to the same color can be found according to the color of the vehicle body at the end of the last sorting, and then the next sorting is performed according to the vehicle body with the most same color, so that the time for changing the color of the robot can be reduced when the subsequent vehicle production sequence for executing the coating is performed, namely, a set of more reasonable production sequence of a coating workshop is integrated according to the color of the vehicle body, and the production efficiency is improved.
Furthermore, the invention also sorts the initial coating production plans which do not have the same vehicle body color for three times according to the vehicle body size;
when the sorting is performed for three times, sorting the initial coating production plans without the test vehicle marks according to the sequence from the small size to the large size of the vehicle body, and arranging the initial coating production plans before the initial coating production plans with the test vehicle marks; and taking the serial numbers corresponding to the initial coating production plans as updated production serial numbers corresponding to the initial coating production plans.
The invention can arrange the initial coating production plan without the test car mark in front, arrange the initial coating production plan with the test car mark behind, and arrange the initial coating production plan without the test car mark in front according to the size of the car body; it can be understood that the size of the vehicle body refers to the size of the vehicle type, when the vehicle body with a large vehicle type is sprayed, the line passing track of the robot is required to be enlarged or complicated, and the vehicle body needs to go back to the original position after the spraying is finished, if the vehicle body with a large vehicle type is arranged in front, the line passing distance and the complexity of the robot are definitely increased, and the rapid line passing of the robot is not facilitated, so that the automatic sequencing method can further reduce the line passing time of the robot, and further improve the production efficiency.
The car bodies of the small car types are ordered in the front, so that when the car bodies of the small car types are sprayed in batches and pass through a line, the conveying system can automatically shorten the car body pitch because of the batch of small car bodies, thereby improving the production interval or the production beat of the subsequent spraying of the robot and improving the production efficiency.
After each initial coating production plan corresponding to each vehicle type identification code in the total production plan is obtained, the initial production sequence numbers in each initial coating production plan can be adjusted according to the test vehicle identification, the vehicle body color, the vehicle body size and the vehicle body assembly condition, and when the initial coating production plans are ordered, the priorities of the vehicle body assembly condition, the vehicle body color, the vehicle body size and the test vehicle identification are used for ordering, so that a special coating production plan capable of automatically ordering and updating can be obtained, and the production efficiency of the automatically generated coating production plan in execution is higher.
For step S2, in a preferred embodiment, when it is detected that a vehicle body arrives at an on-line work site of a paint shop, it is indicated that a vehicle body enters the paint shop, and execution of a paint production plan is started;
the coating production meters are divided into two types, namely a coating production plan of a non-test vehicle and a coating production plan of a test vehicle;
the coating production schedule includes any one or a combination of the following: coating production plan of non-test vehicles and coating production plan of test vehicles;
the coating production plan of the non-test vehicle further comprises: the color of the vehicle body;
the coating production plan of the test vehicle further comprises: vehicle body color, test vehicle identification;
in executing the paint line plan, whichever type of paint line plan is executed:
generating corresponding conveying routes according to the production sequence numbers in each coating production plan so that a conveying system of a coating workshop conveys corresponding vehicle bodies to corresponding positions according to each conveying route;
when a vehicle body spraying request is received, a first target vehicle type identification code in the vehicle body spraying request is extracted, a first target coating production plan corresponding to the first target vehicle type identification code is obtained according to the first target vehicle type identification code, and a corresponding spraying color is generated according to the vehicle body color in the first target coating production plan, so that a spraying robot sprays the corresponding vehicle body according to the spraying color;
if the coating production plan is judged to be the coating production plan of the test vehicle, a second target vehicle type identification code corresponding to the test vehicle identification is further extracted from each coating production plan, and then a vehicle body hanging-out request containing the second target vehicle type identification code is generated according to the second target vehicle type identification code, so that a control device for hanging out the vehicle body can hang out of a coating workshop from the vehicle body corresponding to the second target vehicle type identification code.
When all the coating production plans are detected to be executed and the preset working sites of the coating workshops are detected to pass through, the MES system is requested to send a total production plan containing a plurality of vehicle type identification codes so as to realize the change of the coating plans and meet the requirements of the follow-up workshops.
The invention can automatically recognize the color of the vehicle body of each vehicle type identification code and whether the vehicle is a test vehicle, and then automatically execute the corresponding content without manual recognition or operation.
It should be noted that the painting production plan of the present invention may also include other vehicle type contents or process names, and the corresponding contents may also be different when executing, which is not described herein again. The invention mainly solves the problems of automatic generation and adjustment of the process production sequence of each vehicle body when the coating production plan is executed, and the generated process production sequence can improve the efficiency of each process flow.
For step S3, in a preferred embodiment, after receiving the total production plan sent by the MES system, the production sequence corresponding to the coating production plan may be updated according to each production sequence corresponding to each model identification code in the total production plan, so as to generate an updated production plan;
according to the invention, the vehicle type identification code is defined in the total production plan, and the matched vehicle type identification code is defined in the coating production plan, so that the field of the vehicle type identification code is the unique information of the vehicle body information, and a modified standard is provided for updating the coating production plan into the production master plan of the company MES system. In order to ensure the reliability of the production plan, only one production plan (one vehicle body corresponds to one vehicle type identification code, one vehicle type identification code corresponds to one production plan), namely the uniqueness of the production plan, is provided, and the accuracy of the plan in updating and the accuracy in executing are ensured.
For step S4, in a preferred embodiment, the updated production plan is used as a production plan corresponding to the off-line site of the coating shop.
When the coating production plan is changed to the production main plan of the company MES system, the information of the production sequence field is updated, so that the offline station of the coating is controlled, namely, the production sequence of the production main plan of the company MES system is automatically updated, so that the offline sequence of the vehicle body is controlled, namely, the production plan is automatically updated, and the production plan corresponding to the original production sequence is used as the production plan corresponding to the offline station of the coating workshop.
According to the special process requirements of coating, the invention can automatically acquire the overall production requirements of a company, and automatically generate a special coating production plan for a coating workshop according to the designed logic, so that when a vehicle body is subjected to the coating process, the production sequence of the vehicle body is not required to be manually adjusted, and the production sequence can be automatically arranged according to the special coating production plan which is automatically generated. After the special coating production plan is executed, the total production plan can be automatically updated, namely, the on-line working site of the final assembly process production can execute the corresponding production sequence according to the original main production plan.
Therefore, the invention can realize automatic generation and automatic update of the coating plan, no manual operation is needed in the whole process, the error rate of manual operation is reduced, and the production efficiency of a coating workshop and a final assembly workshop is improved.
The invention can realize the mutual fusion and mutual updating of the production main plan and the special production plan for coating, not only meets the special requirement of a coating workshop, but also can automatically update the original main plan so as not to influence the main production of a company, realize the flexible control of the coating production plan, adjust and generate the production plan suitable for coating at any time according to different requirements of the production of the coating workshop, and realize the automatic switching back to the original main plan, thereby improving the production efficiency of the coating workshop.
