FIG. 1 is a block diagram of an automated processing system according to one embodiment of the present application, and referring to FIG. 1, the automated processing system comprises:
The CNC machine is used for starting a post-processing product;
The intelligent production management system 10 is used for monitoring the service life of a tool used for CNC machine production, sending a tool changing instruction to the scheduling system 20 and sending a first notification indicating shutdown to the machine operation control system 50 after the service life of a target tool reaches a service life threshold;
The machine operation control system 50 is configured to control the instructed first target CNC machine to stop according to the first stop instruction;
The dispatching system 20 is used for dispatching the first AGV trolley after receiving the tool changing instruction;
The first AGV trolley is used for running to the indicated first target CNC machine according to a first scheduling instruction of the scheduling system 20, taking down a target cutter from the first target CNC machine after the first target CNC machine is stopped, running to the cutter cabinet 60, exchanging a target new cutter from the cutter cabinet 60 by using the target cutter, and returning to the first target CNC machine to load the target new cutter to the first target CNC machine;
the intelligent production management system 10 is further configured to send a second notification indicating start-up to the machine operation control system 50 after monitoring that the target new tool is on the first target CNC machine, and monitor and accumulate the service life of the target new tool;
the machine operation control system 50 is further configured to control the first target CNC machine to re-operate after receiving the second notification.
Specifically, a CNC machine (numerical control machine) is a short for a computer numerical control machine (Computer Numerical Control), and is an automated machine controlled by a program. At least one CNC machine is present in the production plant, for example, CNC machine 30 shown in fig. 1 includes CNC machine 1 (31), CNC machine 2 (32). CNC machine n (3 n). Each CNC machine is provided with a processing program. The operation of the CNC machine is controlled by the machine operation control system 50.
The intelligent production management system 10 is installed in a relevant computer in a production shop. The dispatching system 20 is used for dispatching AGV trolleys in a production workshop, planning routes for the AGV trolleys according to dispatching tasks and dispatching the AGV trolleys to execute corresponding tasks.
The AGV carriage is an english abbreviation of an automatic guided vehicle (Automated Guided Vehicle), and is a vehicle equipped with an automatic guiding device such as electromagnetic or optical, capable of traveling along a predetermined guide path, and having safety protection and various transfer functions. The AGV trolley is a combined AGV trolley, is provided with a clamp and has the functions of code scanning, loading and unloading, conveying and the like.
The intelligent production management system 10 can be in communication interaction with the scheduling system 20, the CNC machine and the machine operation control system 50, the scheduling system 20 can be in communication interaction with the AGV trolley, and the machine operation control system 50 can be in communication interaction with the CNC machine.
The intelligent production management system 10 obtains a machine code of the CNC machine to be accessed through code scanning, and accesses the CNC machine to be accessed according to the machine code. The intelligent production management system 10 is in communication with the CNC machine to achieve intercommunication. More specifically, after the machine code is acquired, the intelligent production management writes a numerical value into the covariates of the machining program to be accessed into the CNC machine to achieve the intercommunication state. If the CNC machine does not write the numerical value, the handshake failure between the intelligent production management and the machine is indicated. The intelligent production management system 10 is in communication with the CNC machine as a foolproof mechanism.
Before the CNC machine is started to operate after power-on, the intelligent production management system 10 sends a material preparation instruction to the scheduling system 20 according to production task data synchronized by the machine operation control system 50, and the scheduling system 20 schedules the AGV trolley to feed the CNC machine to be operated according to the material preparation instruction. The feeding comprises cutter feeding and can also comprise production material feeding and the like, and the feeding is not limited to the cutter feeding and the like.
The intelligent production management system 10 monitors the CNC machine to finish machining tools and materials, and then sends a notification for indicating completion of preparation to the machine operation control system 50, and the machine operation control system 50 determines that the CNC machine is ready to complete and then controls the CNC machine to operate to machine and process products.
The intelligent production management system 10 monitors the service life of the on-machine tools to accumulate the service life of each set of on-machine tools. More specifically, the CNC sends the state of the tool being on-machine to the intelligent production management system 10 after the tool is on-machine, and the intelligent production management system 10 starts to monitor the service life of the tool after monitoring that the tool is on-machine. Wherein, each machine tool has corresponding tool monitoring data.
The intelligent production management system 10 monitors the service lives of the cutters in a plurality of CNC machines at the same time, and sends a cutter changing instruction to the scheduling system 20 after the service life of any CNC machine reaches a service life threshold value, wherein the cutter changing instruction carries machine information of the CNC machine to be changed. The intelligent production management system 10 also sends a first notification to the machine operation control system 50 after the service life of a certain CNC machine reaches the service life threshold, so that the machine operation control system 50 controls the corresponding CNC machine to be changed to stop after receiving the first notification.
The CNC machine to be changed, i.e., the first target CNC machine, is not immediately stopped after receiving the first stop command of the machine operation control system 50, but is stopped after the current unprocessed product is produced. The first target CNC machine is one or more of CNC machines 1-n, i.e. each CNC machine may become the first target CNC machine.
The scheduling instruction generates a first scheduling instruction after receiving the tool changing instruction, and sends the first scheduling instruction to a first AGV to be scheduled. The first scheduling instructions are used for guiding the running route of the first AGV and actions to be executed. The first AGV is one of AGV 40 (41-AGV 1, 42-AGV 2, 4m-AGV m).
The first AGV trolley moves to the position of the first target CNC machine according to the first scheduling instruction, takes down the target cutter with the expired service life after the first target CNC machine is stopped, then moves to the cutter cabinet 60, places the target cutter in the cutter cabinet 60, takes away the new cutter from the cutter cabinet 60, returns to the first target CNC machine, and automatically places the new cutter on the first target CNC machine. After the new tool is started, the first AGV trolley or the first target CNC machine station can inform the intelligent production management system 10 that the new tool is started. Specifically, the first target CNC machine feeds back the installation state to the intelligent production management system 10 after the tool is installed, and the intelligent production management system 10 starts to monitor and accumulate the service life of the tool after determining that the tool is installed on the first target CNC machine. Or after the first AGV dolly automatically installs the target new tool into the first target CNC machine, the first AGV dolly sends the installation status of the tool to the intelligent production management system 10.
The intelligent production management system 10 sends a second notification to the tool operation control system 50 after monitoring that a new tool has been set up to instruct the tool operation control system 50 to control the first target CNC tool to re-operate. The intelligent production management system 10 monitors and accumulates the service life of the target new tool after monitoring that the new tool is on-machine.
According to the embodiment, the intelligent production management system 10, the scheduling system 20, the AGV trolley and the like are matched to automatically monitor the service life of the cutter and change the cutter in CNC processing, so that labor is simplified, and compared with the traditional processing workshop, unmanned production management is realized to a certain extent, and labor cost and labor training cost are greatly reduced; the intelligent and automatic interaction ensures that the timeliness of information feedback is high, the system management is unified, the whole system is synchronous, the information is synchronous, the production efficiency is greatly improved, and the tool changing reaction is timely and rapid; the cutter with reduced service life expiration performance is found and replaced in time, so that the yield of products is ensured to a certain extent; the full-automatic tool changing reduces the manual error rate, reduces various accidents such as frequent product quality problems caused by manual operation, tool collision, insufficient clamping and the like and abnormal machining conditions, and improves CNC machining efficiency.
In one embodiment, the scheduling system 20 is specifically configured to send a tool acquisition request to the tool cabinet 60 to acquire a new target tool with the same type as the target tool after receiving the tool changing command;
The tool cabinet 60 is configured to query an existing inventory of target new tools with the same model as the target tools according to the tool acquisition request, and if the existing inventory meets the number of target new tools required by the tool acquisition request, send location information for indicating the location of the target new tools to the scheduling system 20;
The scheduling system 20 is specifically configured to generate a first scheduling instruction according to the position information of the target new tool, the position information of the first AGV trolley to be scheduled, the position information of the first target CNC machine of the tool to be replaced, and the first tool code of the target tool, and schedule the first AGV trolley according to the first scheduling instruction;
the first AGV trolley is specifically configured to, after running to the position of the tool cabinet 60 according to the first scheduling instruction, place the target tool in the old tool area, scan a second tool code of the target new tool located in the target interlayer of the tool cabinet 60, and if the second tool code is matched with the first tool code, take out the target new tool from the target interlayer;
The tool chest 60 is also used to update the remaining inventory of the same model of target new tools after the first AGV takes out the target new tools.
Specifically, after the dispatching system 20 obtains the tool changing instruction, the existing stock of the target new tool with the same model as the target tool is obtained from the tool cabinet 60, and if the existing stock of the tool cabinet 60 meets the requirement of the first target CNC machine, the tool cabinet 60 sends the position information of the position of the target new tool to the dispatching system 20. Wherein the tool cabinet 60 is a storage cabinet for new tools prepared by tool magazine personnel, the tool cabinet 60 has an intelligent tool cabinet 60 system, because the tool cabinet 60 can communicate with the dispatch system 20.
The first scheduling instruction generated by the scheduling system 20 carries first position guiding information of the first AGV trolley to the first target CNC machine, second guiding information of the first AGV trolley from the first target CNC machine to the cutter cabinet 60, and third guiding information of the first AGV trolley from the cutter cabinet 60 to the first target CNC machine.
The first AGV trolley moves to the position of the first target CNC machine according to the first position guide information, moves to the position of the cutter cabinet 60 from the position of the first target CNC machine according to the second position guide information, places the target cutter in the old cutter area, and takes out the target new cutter from the target interlayer of the cutter cabinet 60. The first AGV cart may notify the tool cabinet 60 that the tool is successfully removed after removing the target new tool, or the first AGV cart may notify the dispatch system 20 that the tool cabinet 60 is successfully removed after removing the target new tool, but is not limited thereto. The tool cabinet 60 updates the remaining inventory of new tools of interest after learning that the first AGV has successfully taken the tool.
In this embodiment, the dispatching system 20, the AGV trolley and the tool cabinet 60 (including the intelligent tool cabinet 60 system) cooperate to complete automatic and intelligent tool changing.
In one embodiment, the tool cabinet 60 is further configured to send a tool replenishment notification to the tool magazine if the existing inventory does not meet the target number of new tools required by the tool acquisition request, so as to notify the tool magazine personnel to replenish the tool cabinet 60 with the target new tools having the same model as the target tools;
the tool cabinet 60 is further configured to update the current inventory of the target new tool according to the replenished target new tool.

Specifically, the intelligent production management system 10 monitors the service life of the on-machine tools to accumulate the service life of each set of on-machine tools. More specifically, the CNC sends the state of the tool being on-machine to the intelligent production management system 10 after the tool is on-machine, and the intelligent production management system 10 starts to monitor the service life of the tool after monitoring that the tool is on-machine. Wherein, each machine tool has corresponding tool monitoring data.
The intelligent production management system 10 is installed in a computer of the tool magazine, so that the tool magazine personnel can be prompted to prepare new tools according to requirements by displaying the requirements of the spare tools through pages. After the new cutter body and the new cutter handle are selected by the cutter bin personnel, the new cutter body and the new cutter handle are bound by the code scanning gun through the code scanning tool, the new cutter body and the new cutter handle are assembled into a new cutter, and then the new cutter is sent to the measuring tool 80 for measurement.

The tool holder 60 is thus ready for a new target tool after the target tool life reaches the life threshold.
According to the embodiment, the cutter standby demand is generated according to the service life of the machine tool, and the cutter standby demand is displayed for cutter bin personnel to perform early warning in advance, so that the cutter bin personnel is reminded of the cutter standby in advance, new cutters to be on machine can be timely and effectively prepared in advance, the complicated cutter changing process is reduced, the cutter changing efficiency is accelerated, timely cutter changing is guaranteed, the shutdown waiting time of the CNC machine is reduced, and manual operation is reduced.
In one embodiment, generating backup cutter requirements from the resulting cutter monitoring data includes:
carrying out cutter-using demand prediction on each cutter according to the obtained cutter monitoring data, and generating cutter-preparing demands of cutters with corresponding models according to the cutter-using demand prediction;
Or alternatively, the first and second heat exchangers may be,
And generating corresponding spare cutter requirements after monitoring that the service life of the cutter of any CNC machine table reaches a service life threshold, wherein the cutter monitoring data comprise the service life of the cutter.
Specifically, the intelligent production management system 10 monitors the service lives of the tools in all CNC machines, so the intelligent production management system 10 can count the tool monitoring data according to the tool types, so as to count the service conditions of the tools of each similar type, and further generate the overall spare tool requirements. The intelligent production management system 10 may also generate independent spare blade requirements according to the service life of the tool of each CNC machine, i.e. one CNC machine corresponds to one spare blade requirement.
According to the embodiment, the cutter bin personnel can be enabled to prepare the cutters of the same type at one time through the integral cutter preparation by the model, the repeated cutter preparation is reduced, and the cutter preparation efficiency is improved.

Specifically, the intelligent production management system 10 is configured to monitor the operation status of each CNC machine. The intelligent production management system 10 also presets the sampling frequency of the out-of-organic detection. The intelligent production management system 10 can control when the scheduling system 20 schedules AGV carts to deliver measured products according to the operating state and sampling frequency in the CNC machine production process. Specifically, the intelligent production management system 10 sends a first off-machine detection instruction to the scheduling system 20 when the timing starts to reach one detection time after the CNC machine is started, and the intelligent production management system 10 also sends a second off-machine detection instruction to the scheduling system 20 when the timing starts to reach one detection time after the CNC machine is stopped and rebirth. The CNC machine may feed back the operation state information to the intelligent production management system 10, and the operation state information includes, for example, a production start time, a production re-production time after shutdown, and the like, but is not limited thereto.
The second target CNC machine is one or more of CNC machines 1-n, i.e. each CNC machine may become the first target CNC machine. The second AGV is one of AGV 40 (41-AGV 1, 42-AGV 2, 4m-AGV m). n and m are both positive integers greater than 1.
In one embodiment, the off-board inspection instructions are issued before the second target CNC machine produces the first product to be inspected, such that the dispatch system 20 has enough time to dispatch the second AGV cart, and the second AGV cart has enough time to travel to the second target CNC machine to wait for the first product to be inspected to be produced and to acquire the first product to be inspected.
The intelligent production management system 10 can determine the production time of the first product to be detected according to the preset sampling frequency and the running state of the second target CNC machine, so that an off-machine detection instruction can be issued to the scheduling system 20 in advance according to the production time of the first product to be detected, so that the second AGV trolley runs to the second target CNC machine before the first product to be detected is produced. In order to reduce the waiting time of the second AGV trolley on the second target CNC machine, namely invalid waiting and invalid occupation of the AGV trolley, the intelligent production management system 10 can calculate a reasonable reserved time according to the distribution of the AGV trolley in the production workshop to give the scheduling system 20 and the AGV trolley, so that the scheduling system 20 schedules the second AGV trolley in the reserved time after receiving the off-machine detection instruction to reach the second target CNC machine before the first product to be detected is produced, and the residence waiting time after the second AGV trolley reaches the second target CNC machine does not exceed the preset waiting time. The intelligent production management system 10 sends a first to-be-detected product determination instruction to the second target CNC machine after determining the production time of the first to-be-detected product, and the second target CNC machine determines the first to-be-detected product according to the first to-be-detected product determination instruction and provides the produced first to-be-detected product to the waiting second AGV trolley.
In another embodiment, if the second AGV arrives at the second target CNC machine before the first product to be inspected is produced, the second AGV will directly remove the first product to be inspected after production. The intelligent production management system 10 may further send a first product to be detected determining instruction to the second target CNC machine after determining the production time of the first product to be detected, before the first product to be detected is produced, where the second target CNC machine uses the first product after the first product to be detected is finished as the first product to be detected after receiving the first product to be detected determining instruction, and if the first product to be detected is not removed by the AGV trolley after being produced, the second target CNC machine will place the first product to be detected in the product placement area to be detected of the second target CNC machine, and wait for the second AGV trolley to sample in the product placement area to be detected. Therefore, the first to-be-detected product can be obtained even if the second AGV does not reach the second target CNC machine before the first to-be-detected product is produced. If the second AGV trolley reaches the second target CNC machine platform before the first product to be detected is produced, the second AGV trolley can directly take away the first product to be detected after production is completed, and the second target CNC machine platform does not need to place the first product to be detected in a product placement area to be detected.
The intelligent production management system 10 sends an off-machine inspection instruction to the dispatch system 20 upon monitoring that a certain CNC machine arrives at the inspection time. After receiving the off-machine detection instruction, the dispatching system 20 dispatches one of the AGVs as a second AGV according to the available AGVs in the production plant and the distance or route of the available AGVs from the target CNC machine, and sends a second dispatching instruction to the second AGV, wherein the second dispatching instruction comprises fourth position guiding information of the second AGV running to the second target CNC machine and fifth position guiding information of the second AGV reaching the region to be tested from the position of the second target CNC machine.

That is, the second AGV has arrived in advance at the location of the second target CNC machine waiting before the first product to be detected is produced.
The intelligent production management system 10 sends a sending and testing early warning instruction to the second target CNC machine when determining that the currently produced or to-be-produced product is the first to-be-detected product, and the second target CNC machine sends a sending and testing early warning prompt to the waiting second AGV trolley after receiving the sending and testing early warning instruction so as to prompt the second AGV trolley to prepare for collecting the first to-be-detected product. And the second target CNC machine platform sends the first product after the production is completed after sending the detection early warning prompt to serve as a first product to be detected to be sent to the second AGV trolley. Or the second AGV car actively takes and receives the first product produced by the second target CNC machine after the sending and testing early warning prompt from the second target CNC machine to serve as a first product to be detected.

The on-board detection is performed before the off-board detection, so that the product quality can be roughly and automatically detected before the delivery detection. If the detection in the machine is unqualified, the detection outside the machine is not carried out temporarily, so that some common product problems can be eliminated in advance, and a relatively good first product to be detected is sent to the detection outside the machine.
And a probe is arranged in the second target CNC machine, the second product to be detected in the production and processing process is detected in the machine through the probe, and a corresponding first in-machine detection result is sent to the intelligent production management system 10 through the second target CNC machine.
