Since each electrode workpiece is mounted together with the electrode body 14 and the jig body (jig base 13) in the electrode assembly shop, the identity information of each electrode blank is written into the corresponding RFID chip 15 by the hand-held RFID reader-writer 93, when electrode stock preparation is performed, the RFID chip information of each electrode is read by the hand-held RFID reader-writer 93, and the read RFID chip information can be displayed in the man-machine operation interface 92. Because the automatic processing system has been established and generated tasks automatically according to the naming rules of the program before, an operator can log in a task creation interface of the processing system, and the identity information and the height value of the electrode corresponding to each material level are manually input into the automatic processing system according to the displayed RFID chip information in the task creation interface.
After electrode material preparation is completed, electrode material loading is carried out, and the prepared electrode blank is loaded on the material level of the first material loading frame 11 through a manual or robot. When the electrode is placed on the first feeding frame 11, the side surface of the jig base 13 provided with the RFID chip 15 faces outwards.
Next, the central control system 90 drives the robot 6 to perform RFID scanning on the electrode on each level on the first feeding frame 11 through the wireless RFID reader/writer 61 according to a preset program, and sends the scanned and read information to the central control system 90 through the wireless router 94 in a wireless transmission manner, and the central control system 90 receives and recognizes the RFID information of the electrode on each level and stores the RFID information of the electrode on each level. Since the identity information of each electrode has been manually entered before, the identity of the electrode on each level can be confirmed after the electrode RFID chip on each level is read by the wireless RFID reader 61. In addition, information regarding the electrodes for each level may be queried by the central control system 90 and displayed on the man-machine interface 92.
Before performing automated machining of the electrodes, it is necessary to check the machining state of each device. For example, whether the power control cabinet, the loading rack, etc. are in an automatic mode or in a non-emergency stop state, whether the machining mode of the CNC electrode machining center 2 is set to a memory mode and a remote control mode and reset, whether there are other workpieces on the chuck, whether the robot 6 is in the HOME position (if not, a corresponding "GO HOME" command needs to be executed again, the robot 6 is moved back to the HOME position), whether there is a clamping or gripping state on the gripper of the robot 6, etc.
After the electrode blanks and the mould blanks are placed on the feeding frame 1 manually or by a robot, the equipment such as the CNC electrode machining center 2 and the robot 6 is determined to be in a normal state, and the robot 6 and the CNC machining center 2 are controlled by the central control system 90 to execute electrode machining tasks.
The management execution of the processing task is mainly operated and executed in an automatic processing system, and an action instruction is sent to corresponding production equipment or auxiliary equipment through the automatic processing system, and the specific operation mode is as follows:
in the automated processing system, a switch is made to the "task execution" interface, a click on the "manage" enter "work rack manage" interface, one or more levels to be processed on the first work rack 11 are selected, and a click on "enable". If a specific material level is not selected, electrode blanks on the whole material rack are selected by default for processing. For some electrodes which do not need to be processed or which are not needed temporarily, the electrodes of a certain material level can be disabled by selecting the certain material level and clicking the "disable" and if the "disable" is clicked for selecting a specific material level, the whole material rack is disabled.
After the processed material level is determined, clicking the material changing operation to change the material. The reloading function is based on reloading the started material level, and clicking on "reload" confirms and scans the started material level. For example, to process the electrode blank of the material level 1, the robot 6 takes out the electrode blank of the material level 1 by using the mechanical gripper, and simultaneously scans and reads the RFID chip information of the electrode blank by using the wireless RFID reader 61 on the mechanical gripper and sends the RFID chip information of the electrode blank to the central control system 90, so as to confirm the identity information of the electrode blank taken out from the material level, and the central control system 90 controls the corresponding equipment to execute the corresponding processing procedure according to the identity information of the electrode blank, and records and tracks the processing procedure of the electrode.
If the scanned information is consistent with the recorded information, clicking on a 'reset' interface of 'equipment monitoring', resetting a material frame, clicking on a 'start', controlling a robot 6 to move an electrode blank on a material level to a CNC machining center 2 for machining, and performing the machining process by mutually matching and circularly carrying out the robot 6 and the CNC machining center 2.
The robot 6 is a six-axis robot having multiple degrees of freedom, and a roller type or crawler type travelling mechanism is arranged on a base of the robot 6, and the robot is moved on a robot travelling guide rail 5 by the travelling mechanism. The central control system 90 controls the robot 6 in real time to make accurate actions and process rational logic through a communication protocol connected with the control system of the robot 6. When the robot 6 performs some operations, such as taking out the machined electrode from the CNC electrode machining center 2, the precise positioning of the robot not only depends on the preset stroke, but also requires a sensor to sense the corresponding position, so that the grabbing action is performed at a reasonable grabbing angle. The conventional contact sensor is clearly interfered by external factors, such as splashed chip liquid during cutting of a machine tool and greasy dirt attached to the surface of a workpiece, so that a judgment result is interfered. Therefore, the mechanical gripper of the embodiment adopts the IP 69-grade laser sensor, so that the mechanical gripper can make judgment at a long distance to take corresponding action, and the mechanical gripper not only can resist the interference of splashing of machine tool chip liquid, but also can resist the influence of oil stains attached to the surface of an electrode workpiece.
When the robot 6 grabs the electrode blanks, the manipulator of the robot 6 is clamped on the two grooves 171 of the blind rivet 17. The robot 6 is provided with an RFID read/write device (not shown) on the gripper, which is connected to the central control system 90 via the control system of the robot 6. Thus, when the robot 6 grabs the electrode blanks from the feeding frame 1, the RFID read-write device reads the RFID chip information of the electrode blanks, and transmits the read RFID chip information to the central control system 90. In addition, the electrode body in the electrode blank of the embodiment adopts graphite material, so that the machining and forming of the electrode blank can be completed only by the CNC electrode machining center 2. For electrode blanks of some other materials (such as copper, copper-tungsten alloy, cast iron and other metals), on the basis of using a CNC machining center, a rough machining machine tool, a deburring machine and other devices are additionally added, and the details are not repeated here.
When the electrode blank is fixed on the fixture of the CNC electrode machining center 2, the fixture of the CNC electrode machining center 2 clamps the fixture seat 13, and the electrode body 14 faces upwards.
Referring back to fig. 1-3, the central control system 90 controls the robot 6 to send electrode blanks to the CNC electrode machining center 2 through the PLC electronic control system 91. After the robot 6 sends the electrode blank to the CNC electrode machining center 2, the control system of the robot 6 sends a signal for completing the feeding of the electrode blank to the central control system 90 through the ethernet, the central control system 90 sends a command for controlling the CNC electrode machining center 2 to perform electrode machining to the PLC electronic control system 91 through the ethernet according to the received signal for feeding the electrode blank, the PLC electronic control system 91 sends a machining command to the CNC control system of the CNC electrode machining center 2 through the I/O port according to the received command, and the CNC electrode machining center 2 invokes a preset NC program corresponding to the electrode blank according to the received machining command and performs machining forming on the electrode blank according to the preset NC program.
During electrode machining, if an emergency electrode machining needs to be inserted, the man-machine operation interface 92 is switched back to the 'task execution' interface of the automatic machining system, the 'management' is clicked to enter the 'work-holder management' interface, one or more emergency electrodes on the first work-holder 11 are selected at the 'work-holder management' interface, and then the 'emergency part' is clicked. If a plurality of widgets are selected, the plurality of widgets are processed in order of the selected widgets. The central control system 90 orders the emergency parts in a preferential processing order by an automated control system, and controls the robot 6 and the CNC processing center 2 to prioritize the emergency parts.
When a plurality of processing tasks are performed, the plurality of processing tasks may also be adjusted by the central control system 90. For example, the processing tasks 1 to 6 are sequentially arranged, if the processing task 6 is to be arranged in front of the processing task 2, the processing task 6 is moved upwards to the front of the processing task 2 in a task adjustment interface of an automatic processing system. The downward movement and upward movement of the processing task are the same. In addition, the two processing tasks may be exchanged, or the adjusted processing tasks may be reset, restored, etc., which will not be described in detail herein.
After the electrode processing task of a round is completed, the process returns to the 'create task' interface of the automatic processing system, clicks the 'stock preparation', and scans other electrode blanks on the material frame by using the RFID reader-writer on the mechanical gripper of the robot 6 to determine which material position on the material frame has the electrode blanks, which material position has been processed, which material position has the electrode blanks belonging to the NG state, and the like, so that corresponding operation is performed.
In the embodiment of the invention, the MES electrode intelligent manufacturing and detecting system uses a CNC electrode machining center 2. In other embodiments, multiple CNC electrode machining centers may be used. When the MES electrode intelligent manufacturing and detecting system uses a plurality of CNC electrode machining centers, before automatic machining is started, if one machining center needs to be manually operated for machining or is stopped due to faults, the machining center is set to be in a disabled state through the central control system 90, the specific operation is that before equipment is machined, the machining center needing to be disabled is selected at the equipment monitoring interface of the automatic machining system, and then other machining centers are controlled to machine the electrode by clicking the reset and start according to the operation steps. If a certain device is disabled in the process of processing the device, the device is directly disabled, and the reset and the start are not required to be repeated.
The history records of the electrode machining manufacturing are stored in a server of the central control system 90, and the history records of the machining, such as the machining quantity of each time period and the like, can be checked when the machining of each workpiece is used by logging in an automatic machining system on the central control system 90.
After the CNC electrode machining center 2 processes and forms the electrode workpiece required by electrode blank, the CNC electrode machining center 2 sends electrode machining information to the central control system 90, the central control system 90 receives the electrode machining information and then takes out the electrode workpiece from the CNC electrode machining center 2 through the PLC electric control system 91, the electrode workpiece is placed on the AGV logistics trolley 8, and the AGV logistics trolley 8 sends the electrode workpiece to the CMM three-coordinate measuring instrument 4 for 3D detection. The upper surface of AGV commodity circulation car 8 has transport mechanism, and when AGV commodity circulation car 8 moved the position of CMM three-dimensional measuring apparatu 4, AGV commodity circulation car 8 was high flush with CMM three-dimensional measuring apparatu 4 etc. on the AGV commodity circulation car 8 transport mechanism was with placing the electrode work piece on the AGV surface and was sent on the CMM three-dimensional measuring apparatu 4. In order to enable the electrode workpiece to enter the CMM three-coordinate measuring machine at a correct angle, a positioning table 41 with equal height and level is arranged beside the CMM three-coordinate measuring machine 4, and the positioning table 41 is also provided with a transmission mechanism. The AGV logistics trolley 8 firstly sends the electrode workpiece to the positioning table 41, and then the positioning table 41 sends the electrode workpiece to the CMM three-coordinate measuring machine 4. The whole process from the robot 6 to the AGV logistics trolley 8 to place the electrode workpiece on the CMM three-coordinate measuring machine 4 is controlled by the central control system 90 and the PLC electric control system 91.
After the electrode workpiece is sent to the CMM three-coordinate measuring machine 4, the central control system 90 controls the CMM three-coordinate measuring machine 4 to call a three-coordinate detection program to perform 3D detection on the electrode workpiece through the PLC electronic control system 91, and a detection report is generated to generate a 3D detection report, and the 3D detection report is uploaded to the central control system 90. After receiving the 3D detection report, the central control system 90 clicks the "height" option of the corresponding electrode on the "create task" interface of the automated processing system, and the automated processing system will automatically acquire the height measured by the CMM three-coordinate detector 4 (the height value of the incoming system=the measured height value—the optical knife amount of the processed end face). The machining precision of the CNC electrode machining center 2 and the detection precision of the CMM three-coordinate measuring machine 4 of the present embodiment can reach 0.005 mm, which ensures that the die (electrode) has higher precision and quality. The working principle of the CMM three-coordinate measuring machine 4 is well known to those skilled in the art and will not be described in detail here.
In the process of machining and forming the electrode blanks by the CNC electrode machining center 2, certain machining errors exist in each electrode workpiece due to influences of factors such as cutter abrasion and the like, and the machining errors of each electrode workpiece are different. In the embodiment of the invention, since each electrode workpiece is identified by the RFID chip, and the robot 6 has read the RFID chip information of each electrode blank when removing each electrode blank from the material rack, the 3D detection report generated after the CMM three-dimensional measuring instrument 4 performs 3D detection on each electrode workpiece identifies which electrode workpiece the 3D detection report belongs to, and the machining error of each electrode workpiece can be calculated by 3D detection. After calculating the machining error of the electrode workpiece, the CMM three-coordinate measuring machine 4 compensates the information to the EDM machine 3 by means of the central control system 90 according to the machining error. At this time, the MES electrode intelligent manufacturing and detecting system completes the manufacturing and detecting of the electrode.
After the MES electrode intelligent manufacturing and detecting system completes the manufacturing and detecting of the electrode, the EDM electric spark machine 3 is used for manufacturing a die, and the die manufacturing process is as follows:
after the electrode workpiece is detected in a 3D mode, the central control system 90 controls the AGV logistics trolley 8 to send the electrode workpiece back to the joint of the robot walking guide rail 5 and the AGV magnetic stripe navigation line 7 through the PLC electronic control system 91. Then, the central control system 90 controls the robot 6 to take out a die blank from the material rack 1 through the PLC electric control system 91 and put the die blank into a working groove into which the working fluid is injected by the EDM electric spark processing machine 3, wherein the die blank is made of steel; the robot 6 then sends the detected electrode workpiece to the working tank of the EDM electro-discharge machine 3 into which the working fluid has been injected, and the electrode chuck of the EDM electro-discharge machine 3 clamps the blind rivet 17 by clamping it to the two grooves 171, thereby clamping the electrode workpiece. When the electrode chuck of the EDM electric spark machine 3 clamps an electrode workpiece, the side face of the jig base 13 provided with the RFID chip 15 faces outwards, the jig base 13 is not contacted with working fluid, and the electrode body 14 enters the working fluid to generate a discharge phenomenon. The EDM electric discharge machine 3 calls a discharging program, and executes a discharging step after automatically optimizing the discharging program according to the received compensation information of the corresponding electrode, and through the discharging of the electrode, the electric erosion effect generated by the pulse discharging occurs between the electrode workpiece and the die blank, thereby processing the die blank into a required die workpiece. The formation of one die workpiece often requires the use of several electrode workpieces for machining, so that the CNC electrode machining center 2 is machining and manufacturing other electrode blanks simultaneously when one electrode workpiece is inspected or discharged. Through the logic design of the system, the mould manufacturing process is realized without stopping. And finally, the forming of the die is realized through the discharging of a plurality of electrode workpieces, and finally, the formed die is taken out by a robot 6 and placed at a corresponding position.
For some electrode workpieces that are not used in the batch of die production manufacturing plans, they may be stored in a rack or warehouse. The production state of each electrode workpiece can be identified by reading the information of the RFID chip at the time of gripping by the robot 6. For example, some electrode workpieces have been formed but not 3D inspected, some electrode workpieces have been 3D inspected, and these status information have been uploaded to the server of the central control system 90 in real time while this step is completed. When the next mould production and manufacture plan is carried out, after the robot 6 grabs the electrode workpiece, the RFID read-write device reads the RFID chip information of the electrode workpiece and sends the read result to the central control system 90, and the central control system 90 reads the state of the corresponding electrode workpiece according to the RFID chip information, so that a corresponding action command is sent to corresponding equipment.
The intelligent die manufacturing system further comprises an alarm module, wherein the alarm module comprises an audible and visual alarm, and the audible and visual alarm is connected to a monitoring module of the central control system 90, and the monitoring module is used for monitoring the main shaft state, the cutter state, the machining state and the like of the machine tool in real time. After the system fails or the production flow is finished, the audible and visual alarm reminds the staff of carrying out corresponding next operation through sound and light. In some other embodiments, the alarm module may also be in other ways, such as providing an external computer connected to the central system, sending mail to the external computer through the central control system 90; or to send information to the operator's mobile client over a wireless network, etc.
The equipment in the intelligent die manufacturing system forms a complete processing chain, but the processing process of each processing equipment is independent, so that the automatic processing of other machine tools can not be influenced during the switching, the machine tools switched into the manual mode can be manually operated, and the flexible requirements of enterprises are met. In addition, the intelligent manufacturing system of the die also has the function of urgent single insertion priority and extremely high flexibility. In addition, the intelligent die manufacturing system has strong expansibility, and in workshops with large order quantity, the electrode detection system can be carried with 1-3 CMM three-coordinate measuring machines and one or more intelligent material racks can be selected.
Still further, the entire intelligent manufacturing system is divided into a machining area 98 and a detection area 99. The feeding frame 1, the CNC electrode machining center 2, the EDM electric spark machine 3, the robot walking guide rail 5, the robot 6, the AGV magnetic stripe navigation line 7 and the AGV logistics trolley 8 are arranged in a machining area 98; the CMM three-coordinate measuring machine 4 is disposed in the detection area 99; the AGV magnetic stripe navigation circuit 7 then connects the processing area 98 and the detection area 99, and the AGV stream vehicle circulates between the processing area 98 and the detection area 99. In the detection area 99, a plurality of intelligent material racks may be further provided for storing electrode workpieces and mold workpieces.
