[0002] In the production and use process, the reference seat is very important for the accurate installation and positioning of the electrode in the processing equipment. The electrode with a damaged or missing reference seat is called a reference seat-free electrode, which often needs to be re-bound with a reference seat.

DETAILED DESCRIPTION

[0011] The technical solutions of the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0012] In an embodiment, asFigure 1 As shown, an electrode binding method is provided, which is applied to a controller end for realizing the function of re-binding reference seats for electrodes without reference seats, and includes the following steps S10-S50: S10, obtaining electrode attribute data of an electrode to be bound, and matching a target clamp and a target reference seat according to the electrode attribute data; the electrode to be bound is an electrode without a reference seat.

[0013] Understandably, the electrode to be bound refers to an electrode without a reference seat that needs to be re-bound to a reference seat. The electrode without a reference seat refers to an electrode whose reference seat is invalid or damaged after being bound to a reference seat for the first time. When the original reference seat is detached due to connection failure or other reasons after being bound to a reference seat for the first time, it is called an electrode without a reference seat. When the original reference seat is damaged, it needs to be cut off through a wire cutting process, and it is also called an electrode without a reference seat. The electrode attribute data refers to characteristic parameters for distinguishing different electrodes. The target clamp refers to a specified clamping component for clamping and fixing the electrode to be bound. The target reference seat refers to a specified reference seat for connecting the electrode to be bound. The controller end selects a clamp matched with the electrode to be bound from multiple clamps as the target clamp according to the electrode attribute data, and selects a reference seat matched with the electrode to be bound from multiple reference seats as the target reference seat.

[0014] In an embodiment, the electrode attribute data includes electrode type, electrode shape, electrode size, and electrode use condition; in step S10, i.e., matching the target clamp and the target reference seat according to the electrode attribute data, includes: S101, selecting the target clamp from candidate clamps according to the electrode type and the electrode shape; S102, selecting the target reference seat from candidate reference seats according to the electrode shape, the electrode size, and the electrode use condition.

[0015] Understandably, the electrode attribute data includes electrode type, electrode shape, electrode size, and electrode use condition. The electrode type refers to the category based on the machine stroke of actual processing and the application characteristics of the electrode, including but not limited to small electrodes (applied to finish machining) and large electrodes (applied to rough machining). Small electrodes are suitable for small discharge machine tools, with smaller machine strokes and higher processing precision. Large electrodes are suitable for large discharge machine tools, with larger machine strokes and lower processing precision. Large electrodes require large fixtures, and small electrodes require small fixtures. The electrode shape refers to the characteristics used to represent the cross-sectional shape of the electrode, including but not limited to square electrodes, round electrodes, and irregular electrodes. The electrode size refers to the dimensional characteristics of the electrode in the three-dimensional space, including but not limited to electrode length and electrode cross-sectional size. The electrode use condition refers to the requirements for processing workpieces, including but not limited to coordinate system alignment requirements, processing direction requirements (single direction or multiple directions), etc. The candidate fixture is a plurality of clamping fixtures designed and manufactured in advance according to different electrode types and electrode shapes. The candidate reference seat is a plurality of reference seats designed and manufactured in advance according to the shape, size, and use requirements of the electrode. The candidate fixture can be obtained by purchasing standard parts, or non-standard parts can be designed and manufactured as needed. When there is no suitable candidate fixture or candidate reference seat in the warehouse, a fixture or reference seat model is designed using computer-aided design (CAD) software for automated production. In the reference seat design process, factors such as the connection method of the reference seat and the electrode, and the positioning accuracy requirements are fully considered.

[0016] The controller determines the candidate fixture matching the electrode type and electrode shape as the target fixture, and determines the candidate reference seat matching the electrode shape, electrode size, and electrode use condition as the target reference seat. When the electrode shape, electrode size, and electrode use condition of the electrode without a reference seat are different, the matching target reference seat is also different. The electrode shape affects the design of the electrode mounting hole of the target reference seat, for example, the reference seat for a round electrode (such as a diameter of 30 mm) can be designed as a 40 mm x 40 mm square with a central round electrode mounting hole. The length dimension in the electrode size affects the thickness of the reference seat, for example, the longer the electrode size, the thicker the reference seat required. The electrode use condition affects the structure of the reference seat. For example, when the precision mold electrode requires a positioning error of less than 0.005 mm, the reference seat needs to use a high-rigidity square structure to avoid deformation and coordinate offset. For another example, when the electrode needs to be processed from different angles (such as deep cavity processing scenarios, inclined hole processing scenarios), the reference seat needs to be designed as a rotatable or adjustable structure, for example, through the cooperation of the positioning pin hole and the fixture, to achieve rapid positioning in multi-surface processing.

[0017] This embodiment selects fixtures and reference bases that match the electrodes to be bound based on electrode properties of different dimensions. This can ensure the compatibility between the electrode without a reference base, the target fixture, and the target reference base, and help improve the accuracy of rebinding the electrode without a reference base to the reference base.

[0018] S20. Fix the electrode to be bound to the worktable using the target fixture, and obtain the fixed measurement data of the electrode to be bound.

[0019] Understandably, the controller used to rebind the reference base to the reference base for electrodes without a reference base establishes a communication connection with a high-precision electrode fixing device. The target fixture is a clamping structure installed on the electrode fixing device, capable of accommodating reference base-less electrodes of different shapes and sizes. One end of the electrode is the fixed clamping end, and the other end is the binding connection end. When the reference base-less electrode (the electrode to be bound) is placed on the worktable of the electrode fixing device, the controller clamps the fixed clamping end by adjusting the opening angle of the target fixture, fixing the reference base-less electrode to the worktable and ensuring that the reference base-less electrode will not shift during subsequent connection operations.

[0020] The controller used to re-bind the electrode without a reference base to the reference base also establishes a communication connection with a high-precision measuring instrument, specifically a coordinate measuring machine (CMM). A CMM is a precision three-dimensional measuring instrument primarily used for detecting the dimensions, shape, and relative positions of parts. After the electrode to be bound is fixed to the worktable, the controller acquires the fixed measurement data of the electrode through the measuring instrument. The fixed measurement data refers to the specific physical dimensional parameters occupied by the fixed electrode in space, including but not limited to the shape, position coordinates, and length of the unfixed portion of the electrode.

[0021] S30. Adjust the position of the target reference base according to the fixed measurement data until the reference positioning surface of the target reference base after position adjustment is aligned with the positioning part of the electrode to be bound.

[0022] Understandably, once the electrode to be bound is fixed to the worktable, its fixed measurement data will not change. At this point, the controller adjusts the position of the target reference base so that its reference positioning surface aligns with the positioning part of the electrode to be bound. The reference positioning surface of the reference base refers to the reference plane used to determine the electrode binding position, such as the plane with the best consistency in the reference base or the surface where the electrode mounting hole is located. The positioning part of the electrode refers to the positioning base surface on the electrode that directly contacts the reference positioning surface of the reference base, such as the end face of the binding connection end in the electrode. The reference positioning surface of the reference base completes the binding by connecting with the positioning part of the electrode, which can restrict the electrode's degrees of freedom (such as translation and rotation) and ensure machining accuracy.

[0023] In an embodiment, the step S30, i.e. the position adjustment of the target datum seat according to the fixed measurement data, until the datum positioning surface of the target datum seat after the position adjustment is aligned with the positioning part of the electrode to be bound, comprises: S301, determining the positioning part coordinate of the electrode to be bound according to the fixed measurement data; S302, obtaining the datum positioning coordinate of the target datum seat, and determining the horizontal error value and the vertical error value according to the positioning part coordinate and the datum positioning coordinate; S303, adjusting the position of the target datum seat until the horizontal error value is less than the preset horizontal error threshold value and the vertical error value is less than the preset vertical error threshold value, and confirming that the datum positioning surface of the target datum seat after the position adjustment is aligned with the positioning part of the electrode to be bound.

[0024] Understandably, when the controller end obtains the fixed measurement data of the electrode to be bound through the measuring instrument, the measuring instrument establishes a three-dimensional coordinate system with a fixed reference point as the origin, for example, a three-dimensional coordinate system with the center point of the contact surface between the electrode to be bound and the workbench as the origin. Based on the established coordinate system, the controller end can obtain the positioning part coordinate of the electrode to be bound and the datum positioning coordinate of the target datum seat through the measuring instrument. The positioning part coordinate refers to the center coordinate of the end face of the binding connection end in the electrode to be bound. The datum positioning coordinate refers to the center coordinate of the face where the electrode mounting hole is located in the target datum seat. The horizontal error value is the distance difference of the projection of the positioning part coordinate and the datum positioning coordinate on the horizontal plane, and the vertical error value is the distance difference of the projection of the positioning part coordinate and the datum positioning coordinate on the vertical plane. The preset horizontal error threshold value is a horizontal error critical value for determining the alignment of the datum seat and the electrode, and the preset vertical error threshold value is a vertical error critical value for determining the alignment of the datum seat and the electrode.

[0025] In a specific embodiment, the positioning pin and the positioning block are used as calibration tools, and the controller end adjusts the position of the target datum seat so that the horizontal error value and the vertical error value gradually decrease. When the horizontal error value is less than the preset horizontal error threshold value and the vertical error value is less than the preset vertical error threshold value, it is confirmed that the datum positioning surface of the target datum seat after the position adjustment is aligned with the positioning part of the electrode to be bound. At this time, the end face of the binding connection end in the electrode to be bound is taken as the positioning datum, and the intersection of the center line of the electrode mounting hole in the target datum seat and the end face of the binding connection end is taken as the center point of the end face.

[0026] The embodiment calculates the error value based on the positioning part coordinates of the electrode to be bound and the reference positioning coordinates of the target reference seat, can accurately quantify the position deviation, provides a reliable basis for position adjustment, makes the adjustment process more targeted, can quickly find the best position of the target reference seat, and greatly improves the accuracy and efficiency of position adjustment.

[0027] S40, determine a target connection mode according to the electrode attribute data, connect the fixed electrode to be bound and the position-adjusted target reference seat as a bound reference seat electrode according to the target connection mode, and separate the bound reference seat electrode from the workbench through the target clamp.

[0028] Understandably, the electrode to be bound with different electrode attribute data corresponds to different target reference seats, and at the same time corresponds to different connection modes. The target connection mode is the connection mode of binding the electrode with a specific attribute to the adaptive reference seat. Based on the determined target connection mode, the controller end connects the binding connection end of the electrode to be bound with the electrode mounting hole of the target reference seat, and the reference seat electrode is converted into a bound reference seat electrode. The bound reference seat electrode refers to the reference seat electrode after being bound. Then, the controller end controls the target clamp to loosen the fixed clamping end of the bound reference seat electrode, so that the bound reference seat electrode is separated from the workbench, so as to facilitate subsequent performance test of the bound reference seat electrode.

[0029] In an embodiment, the electrode attribute data includes an electrode type; in step S40, the target connection mode is determined according to the electrode attribute data, which includes: S401, when the electrode type is a small electrode, the adhesive connection mode is determined as the target connection mode; S402, when the electrode type is a large electrode, the mechanical connection mode is determined as the target connection mode.

[0030] Understandably, the small electrode refers to the electrode used for realizing the finishing of the workpiece by discharging, and the diameter of the electrode is less than a critical set value (such as 5mm). The controller end connects the target reference seat with the reference seat electrode by using a suitable connection mode. For small electrodes, an adhesive connection mode is used. In the bonding process, the controller end strictly follows the operation instructions of the adhesive, controls the amount and position of the adhesive, ensures the firmness of the bonding and does not affect the accuracy of the electrode and the reference seat. In the specific bonding connection operation, a high-strength epoxy adhesive is selected to connect the reference seat and the electrode. The controller end controls the robot to uniformly apply the adhesive in the binding connection end of the bound reference seat electrode and the electrode mounting hole (center hole) of the target reference seat, slowly sleeves the target reference seat on the bound reference seat electrode, ensures uniform distribution of the adhesive without air bubbles, makes the adhesive fully solidified, and ensures firm connection.

[0031] The large electrode refers to an electrode used for rough machining of a workpiece by discharging, and the electrode diameter is greater than or equal to a critical set value. For the large electrode, a mechanical connection mode is adopted, which includes but is not limited to a bolt connection mode or a welding connection mode. In a specific bolt connection operation, bolts and nuts of appropriate specifications are selected, and are tightened according to a specified torque value to ensure reliable connection. In a specific welding connection operation, a laser welding process is adopted, welding parameters are controlled to ensure welding quality, and thermal deformation caused by welding is avoided to affect the accuracy of the electrode and the reference seat.

[0032] The embodiment adopts a bonding connection mode for small electrodes, which helps to quickly bind the electrode and the reference seat; and adopts a mechanical connection mode for large electrodes, which improves the binding strength between the electrode and the reference seat. While ensuring the connection strength between the electrode and the reference seat, the adaptability of the electrode in different application scenarios is ensured. The embodiment selects appropriate connection modes according to the actual situation of the electrode, which helps to strictly control various parameters in the connection process, can ensure that the connection between the reference seat and the electrode is firm and reliable, and reduces electrode failures caused by connection problems.

[0033] S50, acquiring appearance detection data, size detection data and discharge detection data of the bound reference seat electrode, and confirming completion of binding when it is determined that the appearance detection data, the size detection data and the discharge detection data meet detection qualified conditions.

[0034] Understandably, the controller end for realizing the function of rebinding the reference seat of the electrode establishes communication connection with the image acquisition device, the three-coordinate measuring machine and the discharge test equipment. The controller end acquires appearance detection data from the image acquisition device, acquires size detection data from the three-coordinate measuring machine, and acquires discharge detection data from the discharge test equipment. The appearance detection data is a quantitative parameter for representing whether defects (such as cracks, scratches, pores, etc.) exist on the surface of the electrode, and whether the connection between the reference seat and the electrode is firm and smooth. The size detection data is a specific physical size parameter occupied by the electrode after being bound with the reference seat in space. The discharge detection data is a discharge test result parameter of the electrode after being bound with the reference seat. The detection qualified condition is a standard pre-set for representing that the electrode after being bound with the reference seat meets the use requirements.

[0035] The embodiment obtains electrode attribute data of the electrode to be bound, matches a target clamp and a target reference seat according to the electrode attribute data, fixes the electrode to be bound to the workbench through the target clamp, and obtains fixed measurement data of the electrode to be bound; position adjustment is performed on the target reference seat according to the fixed measurement data, until the reference positioning surface of the target reference seat after position adjustment is aligned with the positioning part of the electrode to be bound; the target connection mode is determined according to the electrode attribute data, and the fixed electrode to be bound and the target reference seat after position adjustment are connected into a bound reference seat electrode according to the target connection mode; the bound reference seat electrode is separated from the workbench through the target clamp; appearance detection data, size detection data and discharge detection data of the bound reference seat electrode are obtained, and the binding is confirmed to be completed when it is determined that the appearance detection data, the size detection data and the discharge detection data meet the detection qualified conditions. The positioning calibration operation of the target reference seat ensures the accurate connection position of the reference seat and the electrode, and realizes automatic binding of the reference seat electrode without the reference seat, thereby improving the binding efficiency. Meanwhile, the embodiment selects a suitable connection mode according to the actual situation of the electrode, and ensures that the bound reference seat electrode meets the use requirements based on the detection of multiple dimensions such as appearance, size and discharge performance, thereby improving the reliability of the electrode in subsequent processing and use, and ensuring the processing quality of the product.

[0036] In an embodiment, the step S50, that is, the obtaining of the appearance detection data, the size detection data and the discharge detection data of the bound reference seat electrode, includes: S501, obtaining an electrode image of the bound reference seat electrode, performing image recognition processing on the electrode image, and determining surface defect recognition results and connection part recognition results obtained by the image recognition processing as the appearance detection data; S502, obtaining electrode measurement sizes and reference seat measurement sizes of the bound reference seat electrode, and generating size detection data according to the electrode measurement sizes and the reference seat measurement sizes; S503, obtaining discharge stability parameters and discharge efficiency parameters of the bound reference seat electrode under discharge test conditions, and generating discharge detection data according to the discharge stability parameters and the discharge efficiency parameters.

[0037] Understandably, the controller controls the image acquisition device to perform appearance detection on the bound reference seat electrode, obtains an electrode image, and performs image recognition processing on the electrode image to obtain surface defect recognition results and connection part recognition results. The surface defect recognition results are recognition results for characterizing whether there are defects such as cracks, scratches and pores on the surface of the electrode, including normal state and abnormal state. The connection part recognition results are recognition results for characterizing whether the connection part of the reference seat and the electrode is firm and flat, including normal state and abnormal state. The controller controls the three-coordinate measuring machine to comprehensively measure the bound reference seat electrode, to obtain electrode measurement size and reference seat measurement size. The electrode measurement size refers to the length, diameter, and shape size of the electrode part of the bound reference seat electrode. The reference seat measurement size refers to the size of the reference seat part of the bound reference seat electrode. The controller controls the robot to install the bound reference seat electrode into the discharge test equipment simulating the use environment to perform discharge performance testing. For an electrode for electric spark machining, the discharge stability and discharge efficiency performance indicators of the electrode in the discharge process are detected. The discharge stability parameter is a value used to represent the voltage stability of the electrode under specific discharge conditions, for example, recording the voltage change in the discharge process in real time, drawing a voltage-time curve, and calculating the voltage fluctuation range. The discharge efficiency parameter is a value used to represent the energy use efficiency of the electrode under specific discharge conditions, for example, calculating the ratio of discharge output energy to input energy.

[0038] The embodiment can comprehensively and accurately evaluate the effect of rebinding the reference seat of the reference seat-free electrode based on the detection data of the appearance, size, and discharge test in three dimensions.

[0039] In an embodiment, in step S50, that is, the determination that the appearance detection data, size detection data, and discharge detection data meet the detection qualified condition, includes: S504, when the surface defect recognition result and the connection part recognition result are both in a normal state, it is determined that the appearance detection data meets the detection qualified condition; S505, determining a design standard size according to the design drawing information of the bound reference seat electrode, determining a detection size deviation according to the design standard size, the electrode measurement size, and the reference seat measurement size, and when the detection size deviation is less than a preset size deviation threshold, it is determined that the size detection data meets the detection qualified condition; S506, obtaining a stability standard value and an efficiency standard value of the bound reference seat electrode, and when the discharge stability parameter reaches the stability standard value and the discharge efficiency parameter reaches the efficiency standard value, it is determined that the discharge detection data meets the detection qualified condition.

[0040] It can be understood that the normal state of the surface defect recognition result refers to that there is no defect on the electrode surface or the existing defect is small to the extent that can be ignored. The abnormal state of the surface defect recognition result refers to that the defect existing on the electrode surface is not negligible. The normal state of the connection site recognition result refers to that the connection site between the reference seat and the electrode is flat or the uneven part is negligible. The abnormal state of the connection site recognition result refers to that the uneven part existing in the connection site between the reference seat and the electrode is not negligible. When the surface defect recognition result and the connection site recognition result are both in the normal state, it indicates that the appearance detection data meets the detection qualified condition. When the surface defect recognition result or the connection site recognition result is in the abnormal state, it indicates that the appearance detection data does not meet the detection qualified condition.

[0041] The controller end determines the design standard size according to the design drawing information of the bound reference seat electrode. The design standard size refers to the electrode reference size and the reference seat reference size used to ensure the normal use of the electrode in the bound state of the electrode and the reference seat. The controller end determines the detection size deviation according to the difference between the electrode reference size and the electrode measured size, and the difference between the reference seat reference size and the reference seat measured size. The preset size deviation threshold is a detection size deviation critical value preset to ensure the normal use of the electrode. When the detection size deviation is less than the preset size deviation threshold, it indicates that the size detection data meets the detection qualified condition. When the detection size deviation is greater than or equal to the preset size deviation threshold, it indicates that the size detection data does not meet the detection qualified condition.

[0042] The stability standard value is a discharge stability critical value preset to ensure the normal use of the electrode. The efficiency standard value is a discharge efficiency critical value preset to ensure the normal use of the electrode. When the discharge stability parameter is less than the stability standard value, and the discharge efficiency parameter is greater than or equal to the efficiency standard value, it is determined that the discharge detection data meets the detection qualified condition. When the discharge stability parameter is greater than or equal to the stability standard value, and the discharge efficiency parameter is less than the efficiency standard value, it is determined that the discharge detection data does not meet the detection qualified condition.

[0043] The embodiment respectively performs numerical or state judgment on the appearance detection data, the size detection data and the discharge detection data, which can accurately evaluate whether the electrode after rebinding the reference seat meets the use requirement, timely find the potential electrode binding quality problem, and improve the use safety and reliability of the electrode.

[0044] In an embodiment, after the appearance detection data, the size detection data and the discharge detection data of the bound reference seat electrode are obtained in step S50, the method further includes: S507, when it is determined that at least one of the appearance detection data, the size detection data and the discharge detection data does not meet the detection qualified condition, generating a binding failure prompt information.

[0045] Understandably, if at least one of the appearance inspection data, dimensional inspection data, and discharge inspection data fails to meet the inspection qualification conditions, the controller generates a bonding failure message. This bonding failure message is used to report information when an electrode bonding quality problem is detected. The controller sends the bonding failure message to the quality control personnel's terminal, enabling them to be aware of the message and take appropriate action, such as correcting the position of the reference base or replacing the electrode for rebonding.

[0046] This embodiment promptly reports and alerts when potential electrode bonding quality issues are discovered, enabling quality control personnel to quickly identify and address the problems, further ensuring that rebinding electrodes without a reference base meets usage requirements.

[0047] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0048] In one embodiment, an electrode bonding device is provided, which corresponds one-to-one with the electrode bonding method described in the above embodiments. For example... Figure 2 As shown, the electrode bonding device includes a property matching module 10, a fixing measurement module 20, a position adjustment module 30, a connection control module 40, and a qualification detection module 50.

The connection control module 40 is used to determine the target connection method according to the electrode attribute data, and according to the target connection method, connect the fixed electrode to be bound and the target reference seat after position adjustment to form a binding reference seat electrode, and separate the binding reference seat electrode from the worktable through the target fixture; The inspection qualification module 50 is used to acquire the appearance inspection data, size inspection data and discharge inspection data of the bonding reference electrode, and confirm the completion of bonding when it is determined that the appearance inspection data, size inspection data and discharge inspection data meet the inspection qualification conditions.
