They not only improve production efficiency, reduce labor costs, but also improve product quality, ensure personnel safety, and have a wide range of application fields and strong collaborative work capacity.

[0003] However, in the field of palletizing task issuing technology, when the palletizing robot performs palletizing operation, there are usually problems of untimely task data communication and unclear palletizing operation situation, therefore, how to avoid untimely task data communication and unclear palletizing operation situation becomes a problem to be solved. SUMMARY

[0004] The present application aims to provide a palletizing task issuing method based on an MES system to solve the problems of untimely task data communication and unclear palletizing operation situation when the palletizing robot performs palletizing operation.

[0005] In order to achieve the above-mentioned purpose, the present application is realized by the following technical scheme:

[0006] The palletizing task issuing method based on the MES system comprises the following steps:

[0007] Step one: an administrator sets the position coordinate information of the palletizing platform through the MES system, the position coordinate information includes position coordinates and a task area, the task area is defined as a limited area of the workpiece activity range, and the position coordinate information is uploaded to the gateway, and the position coordinate information is transmitted to the PLC for storage through the communication module of the gateway;

[0008] Step two: the PLC starts the corresponding pressure sensor on the palletizing platform according to the position coordinate information transmitted by the gateway, the pressure sensor is used to detect whether there is a signal in the task area, and the position coordinates of the workpiece signal are updated in real time on the touch screen for display;

[0009] Step three: based on the position coordinates of the workpiece signal, the point coordinates of the palletizing robot are updated in real time, and the point coordinate fixed-point operation data and the running program are written and debugged, when the touch screen listens to the instruction of starting the palletizing operation, the feedback is given to the palletizing robot for palletizing operation;

[0010] Step four: real-time monitoring of the position coordinates of the workpiece signal through the pressure sensor, constructing the workpiece coordinate set and recording the workpiece coordinate set in the MES system database; when the touch screen listens to the instruction to end the stacking work, the signal of completing the stacking work is fed back to the MES system, the signal of the pressure sensor is detected and recorded in the MES system database;

[0011] Step five: the administrator evaluates and scores the stacking work according to the MES system database, and stores it in the MES system;

[0012] Step six: when the evaluation score is less than the evaluation threshold, the stacking task is reissued until the evaluation score is qualified.

[0013] Further, the position coordinate information uploaded to the gateway includes the following operations:

[0014] The administrator establishes a connection with the corresponding gateway by setting the IP address and communication protocol parameters of the gateway, activates the gateway, and starts the service of receiving uploaded data;

[0015] The administrator sets the position coordinate information of the stacking platform through the MES system, the position coordinate information includes position coordinates and task area, and uploads the position coordinate information to the gateway;

[0016] After receiving the position coordinate information, the gateway transmits the position coordinate information to the PLC for storage.

[0017] It needs to be explained that the stacking task includes task planning, task issuing, task monitoring and optimization. In the step of uploading the position coordinate information to the gateway: in the task planning, first, the demand of the stacking task is clear, the administrator sets the position coordinates of the stacking platform through the MES system, to accurately find the stacking platform to be stacked on multiple stacking platforms; according to the task area of the stacking platform set, the scope of the stacking task is clear, to prevent the stacking task from being issued smoothly due to unclear stacking task demand; secondly, in the process of uploading the position coordinate information to the gateway, the administrator configures the IP address to ensure that the gateway is assigned a correct IP address that does not conflict with other devices in the network; through the setting of the communication protocol parameters, ensure that the communication protocol supported by the gateway is compatible with other devices in the network, avoid communication failure; through the activation of the gateway device, the gateway connection failure problem is found and handled in time, so as to prevent the problem of delayed task data communication caused by inaccurate gateway configuration.

[0018] Further, the pressure sensor senses the workpiece signal on the task area, constructs the workpiece signal set, and displays the position coordinates of the workpiece signal on the touch screen, including the following operations:

[0019] The PLC transmits the position coordinate information through the gateway to start the corresponding pressure sensor on the palletizing platform, the pressure sensor is used to perceive the workpiece signal on the task area, and a workpiece signal set S={s n |n=1,2,…,N},wherein, s n represents the nthworkpiece signal perceived by the pressure sensor on the task area, and N represents the total number of workpiece signals perceived by the pressure sensor on the task area.

[0020] The workpiece signal set is fed back to the touch screen of the operator, the workpiece signal set is one-to-one corresponding to the number of the operator, and one workpiece signal set corresponds to one number of the operator, and the touch screen displays the position coordinates of the workpiece signals in the workpiece signal set according to a preset display template.

[0021] It should be explained that the PLC transmits the position coordinate information through the gateway to start the corresponding pressure sensor on the palletizing platform, which not only reduces the load of the PLC, reduces unnecessary calculation and processing, but also improves the execution efficiency of the PLC and enhances the stability of the system; by constructing the workpiece signal set, different workpiece signals are identified, and the workpiece signal set can uniquely identify each workpiece signal, so that in a complex production environment, workers can quickly identify and process specific signals, thereby realizing real-time tracking and monitoring of the workpiece state, improving production efficiency and work efficiency; when the palletizing operation fails, the corresponding workpiece signal can be quickly found through the workpiece signal set, reducing the time and cost of troubleshooting.

[0022] Further, the updating of the point operation of the point coordinate of the palletizing robot and the programming and debugging of the running program until the touch screen listens to the instruction of starting the palletizing operation, and feeding back to the palletizing robot for palletizing operation includes the following operations:

[0023] According to the position coordinates of the workpiece signals in the workpiece signal set, the point operation data of the point coordinate of the palletizing robot and the programming and debugging data of the running program are updated in real time until the touch screen listens to the instruction of starting the palletizing operation, and the latest point operation data of the point coordinate of the palletizing robot and the programming and debugging data of the running program are recorded in the MES system database, and the palletizing operation starts.

[0024] It needs to be explained that the operator carries out point coordinate positioning operation on the stacking robot and program writing and debugging according to the position coordinates of the working signals in the workpiece signal set displayed on the touch screen: first, set the reference point, establish the user coordinate system, and map the position coordinates of all workpiece signals in the workpiece signal set on the user coordinate system; then set the motion trajectory and motion parameters of the stacking robot to ensure that the stacking robot moves smoothly and meets the production requirements; then set the program to run and debug and optimize, and comply with the safety operation procedures; after the debugging is completed, the stacking robot is accurately positioned to the position of the workpiece signal, and the operator presses the start button on the touch screen, and the stacking work of the stacking robot starts.

[0025] Further, the pressure sensor monitors the position coordinates of the workpiece signals in real time, constructs the workpiece coordinate set and records the workpiece coordinate set in the MES system database, including the following operations:

[0026] After the stacking task starts, the pressure sensor monitors the position coordinates of the workpiece signals s n in real time according to the workpiece signal set, constructs the workpiece coordinate set W|s n ={(x m , y m , z m )|m = 1, 2, …, M}, wherein (x m , y m , z m ) represents the mth position coordinate of the workpiece signal s n monitored by the pressure sensor during the stacking operation, and records the workpiece coordinate set corresponding to all workpiece signals in the workpiece signal set on the MES system database.

[0027] It needs to be explained that after the stacking operation starts, the position coordinates of the workpiece signals are monitored in real time by the pressure sensor to realize real-time monitoring of the stacking operation, and the deviation of the workpiece position and the time and place where the deviation occurs can be found in time, and potential quality problems and improvement directions can be found.

[0028] Further, when the touch screen listens to the instruction to end the stacking operation, the signal that the stacking operation is completed is fed back to the MES system, the signal of the pressure sensor is detected and recorded in the MES system database, including the following operations:

[0029] When the touch screen listens to the instruction to end the stacking operation, the stacking operation of the stacking robot is completed, and the signal that the stacking operation is completed is uploaded to the gateway, and the gateway is transmitted to the MES system; the signal of the pressure sensor is detected and recorded in the MES system database.

[0030] It needs to be explained that when the stacking operation is completed, the operator presses the end button on the touch screen to upload the signal of the completed stacking operation to the gateway, and the gateway transmits it to the MES system, and the administrator evaluates and scores the completed stacking operation; at the same time, the signal of the pressure sensor is detected, if the pressure sensor fails or the reading is abnormal, it may cause unstable stacking, even collapse accident, so record the pressure sensor output detection signal, provide basis for the administrator to evaluate the completed stacking operation.

[0031] Further, the evaluation and scoring of the stacking operation according to the MES system database, and retaining in the MES system include the following operations:

[0032] The administrator extracts the stacking task data in the MES system database, which includes the operator number, workpiece signal set, workpiece coordinate set and detection signal, evaluates and scores the stacking operation according to the evaluation template and scoring template, generates evaluation data and evaluation score, and retains in the MES system.

[0033] It needs to be explained that the administrator judges whether there is a problem in the stacking operation by checking the stacking task data recorded in the MES system database, such as safety violation, incomplete task, abnormal pressure sensor, etc.; when the stacking operation has a problem, the operator is deducted, such as three points for safety violation, three points for incomplete task, and three points for abnormal pressure sensor; so as to generate evaluation data and evaluation score according to the evaluation template and scoring template, and feedback to the MES system, and the MES system generates visual evaluation report through the preset display template, so as to avoid the problem that the stacking operation is not clear.

[0034] Further, when the evaluation score is less than the evaluation threshold, the stacking task is reissued until the evaluation score is qualified, including the following operations:

[0035] Extract the evaluation score of the stacking operation, when the evaluation score is less than the evaluation threshold, the MES system reissues the stacking task, until the evaluation score is greater than or equal to the evaluation threshold, the evaluation score is qualified, and the stacking task is ended.

[0036] It needs to be explained that when the evaluation score of the stacking operation is less than the evaluation threshold, the administrator can return the stacking task to the original stacking task initial state, automatically issue the stacking task to the operator, and the operator re-performs the stacking until the score is qualified, and the stacking task is issued. Through this stacking task issuing method, not only the efficiency and accuracy of the stacking operation are improved, but also the operation ability and program programming ability of the operator on the stacking robot are greatly improved. Based on the industrial manufacturing background, there are also many stacking robot operation processes in many non-standard product manufacturing automated production lines. Task assignment and issuance through MES can provide strong support for the production management of enterprises.
