[0023] The charging gun connector is the core connection component of the new energy vehicle charging gun. As a key carrier of electrical energy transmission, it is directly related to the safety and transmission efficiency of the charging process. The precision of the constriction groove structure of the terminal installation section is a core factor affecting the connection stability and insertion / removal durability. Multiple processing steps are required to ensure product performance.

[0024] In existing technologies, the aforementioned processing steps for charging gun connectors mostly employ a decentralized operation mode, with each step requiring manual assistance, including manual adjustment of processing parameters, manual transfer of workpieces, and manual quality screening. This approach not only lacks integrated automatic control logic but is also prone to poor dimensional accuracy and distribution consistency of the necking groove due to human error. Furthermore, manual intervention limits production efficiency, making it difficult to meet the demands of large-volume, high-precision production.

[0025] Based on this, this application provides a control method, equipment, and medium for a charging gun connector production equipment to solve the aforementioned technical problems. The technical solutions provided in this application will be described in detail below.

[0026] Firstly, referring to Figures 1 to 4 This application provides a control method for a charging gun connector production equipment, which includes a clamping device 100, a grooving device 200, a trimming device, and a quality inspection device. The control method may include, but is not limited to, the following steps: Step S110: Obtain the finished product modeling data of the plug-in terminal.

[0027] Step S120: Obtain the grooving setting parameters based on the finished product modeling data; wherein, the grooving setting parameters include cutting depth parameters and rotation angle parameters.

[0028] Step S130: Adjust the distance between the clamping device and the grooving device according to the cutting depth parameter, control the clamping device to reciprocate relative to the cutting device to form two symmetrically distributed constriction grooves at the mounting section of the plug terminal, and control the clamping device to rotate the plug terminal after each cut according to the rotation angle parameter until all constriction grooves are cut.

[0029] Step S140: Transfer the cut plug terminals to the trimming device and control the trimming device to trim the burrs and holes of the plug terminals.

[0030] Step S150: Transfer the trimmed plug terminals to the quality inspection device, control the quality inspection device to perform appearance inspection and plug-in / plug-out inspection on the plug terminals, and classify and cut plug terminals with different quality inspection results.

[0031] In steps S110 to S150, this control method addresses the processing requirements of the charging gun connector 600 for new energy vehicles. It derives grooving parameters by acquiring the finished product modeling data of the connector 600, then adjusts the distance between the clamping device 100 and the grooving device 200 based on the cutting depth parameters. The clamping device 100 is controlled to reciprocate relative to the grooving device 200 and rotates to complete the cutting of all the narrowed grooves 610. The workpiece is then transferred to a finishing device for burr trimming and hole diameter trimming. Finally, a quality inspection device performs appearance inspection and insertion / removal inspection, and the workpiece is sorted and unloaded, forming an integrated automatic control process. This method, through the coordinated automatic control of various devices, replaces the manual intervention in the decentralized processes of existing technologies, effectively avoiding human error, improving the processing accuracy and product consistency of the narrowed grooves 610, simplifying the process flow, significantly improving production efficiency, and precisely meeting the high-volume, high-precision production requirements of the charging gun connector 600 in the new energy field.

[0032] It is understood that step S110 may include, but is not limited to, the following steps: Step S210: Based on the finished product modeling data, determine the distribution and depth characteristics of the constriction groove at the plug-in terminal installation section.

[0033] Step S220: Determine the offset angle between each group of symmetrical constriction grooves based on the distribution characteristics.

[0034] Step S230: Determine the rotation angle parameters based on the offset angle.

[0035] Step S240: Determine the cutting depth parameters for each set of symmetrical constriction grooves based on the depth characteristics.

[0036] In steps S210 to S240, the distribution and depth characteristics of the constriction grooves at the plug-in terminal mounting section are accurately extracted from the finished product modeling data. Based on the distribution characteristics, the offset angle between each group of symmetrical constriction grooves is determined, and the rotation angle parameter is derived. Based on the depth characteristics, the cutting depth parameter of each group of symmetrical constriction grooves is determined. This ensures that the determination process of the slotting setting parameters is directly related to and precisely matched with the finished product design requirements. This parameter derivation logic avoids the subjectivity and bias of traditional parameter settings, ensuring that the distribution position and depth dimensions of the constriction grooves strictly conform to the finished product modeling standards. This effectively improves the accuracy of constriction groove processing and product batch consistency, further guaranteeing the connection reliability of the charging gun plug-in terminal in new energy scenarios.

[0037] It should be noted that the connector can have four evenly distributed constriction grooves, i.e., two sets of symmetrical constriction grooves. The offset angle between each set of symmetrical constriction grooves is 90°. This means that after one cut, the connector is rotated 90° by the clamping device and then cut a second time. Similarly, the connector can have six evenly distributed constriction grooves, i.e., three sets of symmetrical constriction grooves. The offset angle between each set of symmetrical constriction grooves is 60°. For connectors with partially unevenly distributed but symmetrical constriction grooves, for example, a connector with six constriction grooves, where the offset angle between the first and second sets of symmetrical constriction grooves is 30°, and the offset angle between the second and third sets is 70°, then the corresponding rotation angle parameters are: after the first cut, rotate 30° for the second cut, and then rotate 70° for the third cut.

[0038] It is understood that step S130 may include, but is not limited to, the following steps: Step S310: Obtain the initial end center coordinates of the plug-in terminal and the cutter edge coordinates of the cutting device when the terminal is clamped by the clamping device.

[0039] Step S320: Determine the target end center coordinates of the plug-in terminal based on the cutting depth parameters, the initial end center coordinates, and the cutter edge coordinates.

[0040] Step S330: Adjust the distance between the clamping device and the grooving device according to the center coordinates of the target end, so as to adjust the extension length of the plug terminal toward the cutting device and make the center of the plug terminal and the cutter of the cutting device be on the same horizontal plane.

[0041] In steps S310 to S330, by acquiring the initial end center coordinates of the plug terminal when it is clamped by the clamping device and the cutter edge coordinates of the cutting device, and combining them with the cutting depth parameters, the target end center coordinates of the plug terminal are accurately determined. Then, based on these target coordinates, the distance between the clamping device and the grooving device is adjusted. This achieves precise control over the length of the plug terminal extending towards the cutting device and ensures that the center of the plug terminal is on the same horizontal plane as the cutter of the cutting device. This precise adjustment method based on coordinate calculation effectively avoids potential positional deviations in traditional distance adjustments, improves the dimensional accuracy and positional consistency of the grooving cut, and further guarantees the processing quality of the charging gun plug terminal, enabling it to stably meet the stringent requirements for connection reliability in new energy scenarios.

[0042] It is understood that after step S150, the following steps may be included, but are not limited to: Step S410: Obtain the finished product image of the plug terminals whose quality inspection result is good.

[0043] Step S420: Based on the finished product image, obtain the actual depth of each constriction groove in the plug-in terminal, and based on the finished product modeling data, determine the depth characteristics of the constriction groove at the installation section of the plug-in terminal.

[0044] Step S430: Obtain the average tolerance for the machining of the plug-in terminal based on the actual depth and depth characteristics of each corresponding terminal.

[0045] Step S440: Generate the cutting depth compensation amount based on the average tolerance and the preset error threshold.

[0046] Step S450: Adjust the cutting depth parameters according to the cutting depth compensation amount.

[0047] In steps S410 to S450, the processing of the charging gun connector may be affected by objective factors such as tool wear and material property fluctuations, leading to a deviation between the actual depth of the constriction groove and the depth feature in the finished product modeling data. Long-term accumulation of this deviation can affect product quality consistency. By acquiring finished product images of qualified connectors, the actual depth of each constriction groove is obtained. This is compared with the depth feature to calculate the average tolerance. Then, a cutting depth compensation amount is generated based on a preset error threshold, and the cutting depth parameters are adjusted, forming a closed-loop control logic of processing-inspection-compensation. This dynamic compensation method can correct minor deviations in the processing in real time, continuously optimize the cutting depth parameters, and ensure that the depth of the constriction groove in subsequent processing always accurately matches the product design requirements. This further improves the processing accuracy and batch stability of the charging gun connector, providing continuous assurance for reliable connections in new energy scenarios.

[0048] It is understood that the trimming device includes a grinding structure 310, a narrowing structure 320, and an interlocking structure 330. Step S140 may include, but is not limited to, the following steps: Step S510: Insert the cut plug-in terminal into the grinding column of the grinding structure, and control the grinding column to rotate to remove the burrs formed by cutting the constriction groove of the plug-in terminal.

[0049] Step S520: Insert the deburred plug-in terminal into the constriction structure, and control the constriction structure to squeeze the mounting section of the plug-in terminal to adjust the shape and diameter of the mounting section.

[0050] Step S530: Insert the reduced-diameter plug terminal into the plug-in post of the plug-in structure to adjust the aperture of the mounting section to match the target charging plug post.

[0051] In steps S510 to S530, the purpose of grinding is to remove the burrs formed by cutting the constriction groove of the plug terminal, so as to avoid the burrs affecting the subsequent assembly compatibility and connection reliability; the purpose of constriction is to squeeze the mounting section of the plug terminal through the constriction structure, adjust the shape and diameter of the mounting section, and make it initially close to the target assembly size; the insertion is performed after constriction because the material is prone to elastic rebound or uneven diameter during the constriction process. By inserting the constricted plug terminal into the insertion post of the insertion structure, the constriction deviation can be accurately corrected, so that the diameter of the mounting section is completely matched with the target charging plug post.

[0052] By combining grinding, narrowing, and interlocking processes, the burr defects left by cutting are effectively eliminated. The combination of narrowing and shaping and interlocking calibration precisely controls the aperture and shape of the mounting section, improving the processing quality and assembly compatibility of the charging gun connector. This ensures the connection stability and smooth insertion / removal in new energy scenarios, further meeting the high-precision assembly requirements of charging components in the new energy field.

[0053] It is understood that the charging gun connector production equipment includes an oil immersion device 400, located between the finishing device and the quality inspection device. The oil immersion device includes an oil bottle, a level sensor, a particle sensor, and a moisture content sensor. The oil bottle has an oil inlet and an oil outlet. After step S140, the following steps may be included, but are not limited to: Step S610: Immerse the trimmed connector in an oil bottle to coat the surface of the connector with an oil film, and then transfer the oiled connector to the quality inspection device for subsequent processing.

[0054] Step S620: Acquire liquid level data from the liquid level sensor, particle data from the particle sensor, and moisture content data from the moisture content sensor.

[0055] Step S630: When the liquid level sensing data is less than or equal to the preset liquid level threshold, control the oil inlet to open so as to add new oil into the oil bottle.

[0056] Step S640: When the particle sensing data is greater than or equal to the preset impurity threshold, control the oil drain port to open until all the old oil in the oil bottle is discharged. Then close the oil drain port and open the oil inlet port to add new oil to the oil bottle.

[0057] Step S650: When the moisture content data is greater than or equal to the preset moisture threshold, control the oil drain port to open until half of the old oil in the oil bottle is drained. Then close the oil drain port and open the oil inlet port to add new oil to the remaining old oil in the oil bottle.

[0058] In steps S610 to S650, the purpose of immersing the plug-in terminals in oil is to form a uniform oil film on their surface. This film can isolate the terminals from air and moisture to prevent oxidation and corrosion, and also act as a lubricant to improve the smoothness of insertion and removal during subsequent assembly. In addition, it can cover any minor surface defects that may remain after processing, ensuring the connection reliability and service life of the charging gun plug-in terminals in new energy scenarios.

[0059] This oil change control logic monitors the key states of the oil in the oil bottle in real time through level sensors, particle sensors, and moisture content sensors. It adopts precise oil replenishment, full oil change, or partial oil change strategies for different abnormal situations to ensure that the oil always maintains the required level, cleanliness, and purity. This avoids the decline in oil immersion effect due to insufficient oil, excessive impurities, or excessive moisture, which would affect the terminal processing quality. At the same time, it eliminates the need for frequent manual detection and judgment, realizing automated and precise control of oil management. This not only improves production efficiency but also ensures the stability and consistency of oil immersion treatment, providing continuous support for the high-quality production of charging gun connector terminals.

[0060] It is understood that the quality inspection device includes an image detection structure 510, and the appearance inspection in step S150 may include, but is not limited to, the following steps: Step S710: The trimmed connector is moved to the image detection structure, and quality inspection images of the connector from multiple angles are obtained through the image detection structure; Step S720: Extract the actual finished product data of the plug-in terminals based on multiple quality inspection images; Step S730: Perform similarity matching between the actual finished product data and the finished product modeling data to obtain the processing matching degree, and obtain the appearance quality inspection result based on the processing matching degree.

[0061] In steps S710 to S730, multiple-angle quality inspection images of the plug-in terminal are obtained through the image detection structure, which can comprehensively and without dead angles capture the appearance and structural details of the terminal, avoiding the omission of defects caused by single-angle detection. Subsequently, the actual finished product data is extracted and compared with the finished product modeling data for similarity matching. The objective processing matching degree is used as the basis for judging the appearance quality inspection result, replacing the subjective judgment of manual inspection. This standardized and automated appearance inspection method not only improves the quality inspection efficiency, but also ensures the consistency and accuracy of the appearance quality inspection result. It can accurately screen out defective products whose appearance or structure do not meet the requirements of the finished product modeling data, making the distinction between good and bad products more reliable, effectively preventing defective products from flowing into subsequent processes, ensuring the shipping quality of the charging gun plug-in terminal, and meeting the high-quality requirements for charging components in the new energy scenario.

[0062] It can be understood that the quality inspection device includes a force sensor 521 and a simulated plug column 522. The diameter of the simulated plug column matches the charging plug column to which the plug-in terminal is targetedly docked. The force sensor is used to detect the force condition of the simulated plug column. The plug and unplug detection in step S150 may include but is not limited to the following steps: Step S810: Insert the trimmed plug-in terminal into the simulated plug column, and obtain the maximum plug and unplug force of the plug-in terminal when it is pulled out from the simulated plug column through the force sensor.

[0063] Step S820: Obtain the plug and unplug quality inspection result based on the maximum plug and unplug force and the preset plug and unplug force threshold.

[0064] In steps S810 to S820, by using a simulated plug column with a diameter matching that of the charging plug column to which the plug-in terminal is targetedly docked, combined with the force sensor to detect the maximum plug and unplug force during the plug and unplug process, accurate simulation detection of the plug and unplug performance of the terminal is achieved, replacing the subjective judgment and experience dependence of manual plug and unplug, and improving the objectivity and reliability of the plug and unplug quality inspection. This standardized inspection method can effectively screen out products with unqualified plug and unplug performance, ensuring that the charging gun plug-in terminals flowing into the market have stable plug and unplug smoothness and connection reliability, meeting the safety use requirements during the charging process in the new energy scenario.

[0065] Specifically, when the maximum plug and unplug force is less than the preset plug and unplug force threshold, it indicates that the hole diameter of the installation section of the plug-in terminal is too large, resulting in too loose connection and unable to ensure stable contact, and it is also judged as unqualified for the plug and unplug quality inspection; when the maximum plug and unplug force is greater than or equal to the preset plug and unplug force threshold, it is judged as qualified for the plug and unplug quality inspection.

[0066] When both the appearance quality inspection result and the plug and unplug quality inspection result are qualified, the overall quality inspection result is qualified. Finally, the products with qualified quality inspection results are transferred to the good product placement area, and the products with unqualified quality inspection results are transferred to the defective product placement area.

[0067] Secondly, the application also provides a charging gun connector production equipment, including: at least one memory, at least one processor and at least one program, the program being stored in the memory, and the processor executing one or more programs to implement the control method of the charging gun connector production equipment described above.

[0068] In this charging gun connector production equipment, the grooving setting parameters are derived by acquiring the finished product modeling data of the connector. Then, the distance between the clamping device and the grooving device is adjusted according to the cutting depth parameters. The clamping device is controlled to reciprocate relative to the grooving device and coordinate with the rotation to complete all the narrowing groove cutting. Subsequently, the workpiece is transferred to the finishing device for burr trimming and hole diameter trimming. Finally, the quality inspection device completes the appearance inspection and insertion / removal inspection and sorts and unloads the workpiece, forming an integrated automatic control process. This method replaces the manual intervention of the decentralized processes in the existing technology through the coordinated automatic control of each device, effectively avoiding human operation errors, improving the processing accuracy of the narrowing groove and product consistency, while simplifying the process connection, significantly improving production efficiency, and accurately meeting the needs of the new energy field for large-volume, high-precision production of charging gun connectors.
