[0047] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0048] The present application embodiment provides a graphite electrode preparation production line, referring to Figure 1 as well as Figure 2In this embodiment, the production line includes: a processing station, a robot and a control system, wherein the processing station includes a plurality of processing stations, each processing station is provided with a processing module, and the processing modules communicate with each other.

[0049] Specifically, the processing station also includes a material storage station, and the material storage station includes a raw material station, a finished product station and a waste product station.

[0050] Specifically, the processing station further includes a control station, and the control station is provided with an acquisition module.

[0051] The control system is used to assign tasks to the processing module and the robot based on the acquired task list, and send a start processing instruction to the robot to realize control of the processing module and the robot.

[0052] The processing module is used to process the graphite electrode based on the processing task assigned by the control system when it is detected that the graphite electrode is at the preset processing position of the corresponding processing station; it is also used to send a movement request instruction to the robot according to the processing requirements during the processing process; and it is also used to send an end processing instruction to the robot when the processing is completed.

[0053] The robot is used to move the graphite electrode between the preset processing positions of the processing stations when receiving a start processing instruction from the control system or an end processing instruction from the processing station.

[0054] It can be understood that when the end processing instruction of the first processing station is received, the robot will move the graphite electrode processed by the corresponding processing module of the first processing station to the preset processing position of the second processing station according to the second preset trajectory, wherein the second processing station is the processing station corresponding to the next process task of the first processing station.

[0055] By utilizing the above production line, the tedious process of manually comparing the task list to determine the graphite electrode to be removed is eliminated, and the labor cost of removing the graphite electrode and moving it to the processing station is also eliminated.

[0056] It is also used to move the graphite electrode to the corresponding preset processing position when receiving a movement request instruction of the processing station.

[0057] Specifically, when receiving a movement request instruction of the first processing station, the robot moves the graphite electrode according to a third preset trajectory at the corresponding preset processing position.

[0058] Specifically, the multiple processing modules corresponding to the multiple processing stations include an acquisition module, a sawing sub-module, a deburring sub-module, a separation sub-module, a connection sub-module, a detection sub-module, an installation sub-module and a pasting module; wherein, the multiple processing stations can be set according to a preset process sequence or in a random order, without specific limitation.

[0059] The acquisition module is used to acquire the task list in the program list so that the control system can control the processing module and the operation of the robot based on the task list.

[0060] Specifically, when the control system obtains the task list by scanning the program single barcode, it sends a start processing instruction to the robot based on the task list.

[0061] Step S10: Scan the program barcode to obtain a task list, and take out the graphite electrode based on the task list;

[0062] Specifically, when receiving the start processing instruction from the control system, the robot takes out the graphite electrode from the raw material station according to the first preset trajectory and places it at the processing position of the corresponding processing station of the sawing sub-module.

[0063] When each processing module detects that a graphite electrode is placed at the corresponding processing position, it starts to process the graphite electrode. The detection method can be through a pressure sensing unit, a photoelectric sensing unit, a magnetic induction unit or an ultrasonic sensing unit, etc., and there is no specific limitation.

[0064] Wherein, the manipulator is further used to take out the graphite electrode from the raw material station when receiving a start processing instruction from the control system;

[0065] The sawing sub-module is used to saw the graphite electrodes taken out from the raw material station by the robot; traditional graphite electrode preparation mainly adopts manual preparation method, which requires manual use of a sawing machine to guide the graphite electrodes, push the materials and cut them according to the drawing dimensions, which is prone to errors. Dust is generated during the sawing process, which will cause certain harm to the body over a long period of time. At the same time, safety accidents such as mechanical injuries may occur during the sawing process.

[0066] Step S20, guiding, pushing and sawing the graphite electrode in sequence;

[0067] By using the above-mentioned production line, the graphite electrodes are sequentially guided, pushed and sawed; the problems of easy errors, dust generation and safety accidents in the manual material preparation process are solved, while labor costs are saved, the accuracy of sawing processing is improved, and the efficiency of sawing processing is improved.

[0068] When the sawing process is completed, the sawing sub-module sends an end processing instruction to the robot. The robot continues to move the sawed graphite electrode from the current processing position to the corresponding processing station of the burr module according to the task list, and places it at the processing position of the corresponding processing station of the burr module.

[0069] The deburring submodule is used to deburr the graphite electrode that has been sawn.

[0070] The neutron module is used to measure the size of the deburred graphite electrode.

[0071] Step S30, deburring and centering the sawn graphite electrode in sequence to obtain the size of the sawn graphite electrode, and writing the measured size data into the chip;

[0072] By using the above-mentioned production line, the graphite electrodes after sawing are deburred and center-processed in turn to obtain the size of the graphite electrodes after sawing, and the measured size data is written into the chip; in the process of deburring the graphite electrodes, the harm to the human body caused by the large amount of dust generated during traditional manual deburring is avoided.

[0073] Specifically, the centrifuge submodule may be a camera centrifuge submodule composed of a camera unit and a centrifuge unit, or a dotting centrifuge submodule composed of a dotting unit and a centrifuge unit, etc., which is not specifically limited.

[0074] As an example, when receiving a movement request instruction from the camera unit, the manipulator rotates the deburred graphite electrode by a preset angle, and the neutron submodule includes:

[0075] a camera unit, configured to capture a first image of the deburred graphite electrode and a second image of the graphite electrode after being rotated by a preset angle;

[0076] a centering unit, configured to calculate a size of the deburred graphite electrode according to the first image and the second image;

[0077] The robot is further configured to rotate the deburred graphite electrode by a preset angle after the camera unit captures the first image.

[0078] Specifically, the preset angle may be 180 degrees, 360 degrees, 720 degrees, etc., and is not specifically limited.

[0079] Specifically, two sets of length and width data can be obtained by taking two photos. If the two sets of data are inconsistent, two more photos are taken until the two sets of data are consistent.

[0080] Specifically, according to the above two images, the length and the width of the graphite electrode are obtained respectively.

[0081] Therefore, by utilizing the above production line, during the centering process of the graphite electrodes, the present application can more accurately measure the length and width of the graphite electrodes compared to the traditional manual measurement method.

[0082] The connecting submodule is used to connect the copper electrode seat with the graphite electrode that has been measured in size to obtain a connected graphite electrode, wherein the copper electrode seat is taken out from the raw material station by the robot when the end processing instruction of the neutron submodule is received.

[0083] Specifically, when receiving a movement request instruction from the bonding unit, the manipulator clamps the graphite electrode after size measurement at a preset height and moves along a preset trajectory at the preset height. An aluminum plate is provided on the upper surface of the copper electrode holder. The connecting submodule includes:

[0084] A gluing unit, used for extruding a preset amount of glue onto the surface of the aluminum plate;

[0085] Wherein, during the process of extruding the preset amount of glue, the robot clamps the size-measured graphite electrode at a preset height and moves along a preset trajectory at the preset height.

[0086] Specifically, the gluing unit extrude the preset amount of glue onto the surface of the aluminum plate. At the same time, the robot clamps the graphite electrode with measured dimensions and moves it along a preset trajectory at a preset height, wherein the preset trajectory can be around the gluing surface (upper surface) of the aluminum plate, or around and in the center of the gluing surface of the aluminum plate.

[0087] Specifically, in the process of gluing the graphite electrode after the separation process to the copper electrode seat, after a preset amount of glue is extruded onto the copper electrode seat, the copper electrode seat and the graphite electrode after the separation process are pressed together for 3-5 minutes.

[0088] Specifically, the pressing time may be 3 minutes, 4 minutes, etc.

[0089] Step S40, connecting the graphite electrode after the separation process to the copper electrode holder;

[0090] By utilizing the above production line, the graphite electrode that has undergone centering processing is connected to the copper electrode holder, and the graphite electrode and the copper electrode holder can be accurately aligned and glued together, thereby reducing errors.

[0091] It should be noted that, at present, the method of connecting the graphite electrode and the copper electrode seat is hinged. Specifically, a circular hole is milled at the center of the copper electrode seat, one end of the graphite electrode is placed in the circular hole, and bolts are provided around the circular hole on the upper surface of the copper electrode seat, and the graphite electrode is fixed to the copper electrode seat with bolts; this connection method will cause the part of the graphite electrode inside the circular hole to be unusable for the next process, increase the material consumption of the graphite electrode, and generate unnecessary waste.

[0092] In this embodiment, the bonding method is adopted, and there is no need to mill a circular hole on the copper electrode seat, which simplifies the manufacturing process of the copper electrode seat; and there is no need to place a part of the graphite electrode into the circular hole, and it is only necessary to glue the aluminum plate provided on the surface of the copper electrode seat with glue. All the materials of the graphite electrode can be used in the next process, saving the materials of the graphite electrode.

[0093] Moreover, the glue used in the bonding process of this embodiment is firmly bonded during bonding, and can be easily removed from the aluminum plate by scraping with a blade after air drying. Therefore, after all processes are completed, no additional processes will be added when the copper electrode holder is recycled.

[0094] The detection submodule is used to measure the height and resistance of the connected graphite electrodes and detect whether the resistance is qualified.

[0095] Specifically, the height and resistance of the connected graphite electrode are detected by the detection submodule, wherein the height can be obtained by laser scanning detection, or by measuring the distance from the upper end of the connected graphite electrode to the lower end (baseline) by a measuring needle, or by calculating the coordinates of the dots made by a dotting unit; the resistance can be measured by a multimeter, or by other resistance testing units.

[0096] Specifically, when the detection submodule sends an end-processing instruction to the robot, the robot places the connected graphite electrodes with qualified resistance into the finished product station, and the robot places the connected graphite electrodes with unqualified resistance into the waste station.

[0097] An input module is used to input the size data and height data into the chip.

[0098] Specifically, the dimensional data and height data obtained by the above measurements are entered into the chip so that the EDM process can calculate the workpiece coordinate system of the graphite electrode based on the dimensional data during processing, and determine the processing height of the graphite electrode based on the height data.

[0099] Step S50, measuring the height and resistance of the graphite electrode connected to the copper electrode holder, and writing the measured height data into the chip;

[0100] By using the above production line, the measured size data and height data are entered into the chip. The measured size, height and resistance of the connected graphite electrode are more accurate, do not consume manpower, and improve the overall processing efficiency.

[0101] The installation submodule is used to install the chip on the connected graphite electrode in the finished product station, so that when the EDM process uses the connected graphite electrode, the size data and height data are obtained by scanning the chip, wherein the connected graphite electrode in the finished product station is the connected graphite electrode with qualified resistance size placed by the robot when the end processing instruction of the detection submodule is received.

[0102] Specifically, the chip is mounted on the connected graphite electrode in the finished product station in a hinged manner, and the mounting position is on the copper electrode seat of the connected graphite electrode.

[0103] Step S60: mounting the chip on the connected graphite electrode, and pasting a corresponding barcode on the copper electrode holder of the connected graphite electrode with qualified resistance, thereby completing the preparation of the graphite electrode.

[0104] The chip is mounted on the connected graphite electrode using the production line to complete the preparation of the graphite electrode.

[0105] In addition to the above modules, the processing module also includes:

[0106] The pasting module is used to paste the corresponding bar code on the copper electrode seat of the connected graphite electrode with qualified resistance after the chip is installed on the connected graphite electrode in the finished product station.

[0107] Specifically, after the mounting submodule finishes processing, the pasting module pastes the corresponding barcode on the copper electrode seat of the connected graphite electrode with qualified resistance.

[0108] A corresponding barcode is pasted on the copper electrode seat of the connected graphite electrode with qualified resistance, so that the connected graphite electrode with qualified resistance can be accurately entered into the electrode library for EDM process.

[0109] Using the above production line, the graphite electrodes are sequentially sawed, deburred, centered, connected, inspected, installed and pasted. No manual participation is required in the entire graphite electrode preparation process, which saves labor costs, reduces errors caused by manual participation, and improves the graphite electrode preparation efficiency.
