[0036] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1 To the attached Figure 11 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.

[0037] The present application embodiment discloses a method for producing an electrical connector. Figure 1 , the method comprising: Step S101: providing a positioning hole at a first end of the copper sheet.

[0038] The electrical connector of the embodiment of the present application is applied to a photovoltaic junction box, and the electrical connector is used to connect the photovoltaic junction box and the photovoltaic module.

[0039] The positioning holes are used to locate the position of the electrical connector on the copper sheet. For example, the positioning holes are evenly punched on the first end of the copper sheet, and the distances between adjacent positioning holes are the same.

[0040] For example, please refer to Figure 3 , positioning holes 32 are evenly punched on the first end of the copper sheet 31.

[0041] Step S102: Forming a rectangular array of through holes on the second end of the copper sheet.

[0042] The second end is the end of the copper sheet opposite to the first end.

[0043] The rectangular array of through holes are rectangular and uniformly arranged on the second end of the copper sheet.

[0044] For example, referring to Figure 3 Uniformly punching rectangular through holes on the second end of the copper sheet 31 to obtain a rectangular array of through holes 33.

[0045] Step S103: Cutting the copper sheet according to the positioning holes to obtain a first intermediate piece.

[0046] The cutting process is used to partially divide the copper sheet and retain the connection point on the first end of the copper sheet. For example, referring to Optionally, referring to Figure 3 Cutting the copper sheet 31 according to the positioning holes to obtain a first intermediate piece 24 and a remaining copper sheet that is not cut.

[0047] Step S104: Performing a rounding process on the first intermediate piece to obtain a second intermediate piece, and the second end of the second intermediate piece forms an inner ring structure.

[0048] The rounding process is used to bend the first intermediate piece along a certain radius to form a cylindrical second intermediate piece. For example, the rounding operation adopts a mandrel rounding method, that is, a mandrel die is installed on the main shaft of a lathe, and its shape matches the inner diameter of the electrical connector. The second end of the first intermediate piece is fixed on the mandrel die. The rounding device rotates at low speed, and the pressing wheel of the rounding device moves axially along the mandrel die, forcing the second end of the first intermediate piece to wrap around the mandrel to form a shape.

[0049] For example, referring to Figure 3 Performing a rounding process on the first intermediate piece 34 to obtain a second intermediate piece 35 based on the second end of the first intermediate piece. After forming the second intermediate piece 35, the connection point of the first end of the remaining copper sheet is still retained.

[0050] Step S105: Adding a clamp assembly to the end of the second intermediate piece away from the inner ring structure to obtain an electrical connector.

[0051] The clamp assembly is used to fasten the second intermediate piece so that the second intermediate piece can form a stable cylindrical structure.

[0052] Further, after generating the electrical connector, one end of the electrical connector is still fixed on the first end of the remaining copper sheet.

[0053] For example, referring to Figure 3, add a clamp assembly 36 to the second middle piece 35 to obtain an electrical connector 37.

[0054] Step S106: Acquire a test image of the electrical connector.

[0055] The test image is obtained by photographing the electrical connector at a preset photographing angle. For example, the test image is obtained by photographing the electrical connector along the axial direction and the radial direction of the electrical connector.

[0056] Furthermore, since one end of the electrical connector is still fixed to the first end of the copper sheet, when acquiring the test image of the electrical connector, test images of multiple electrical connectors can be acquired.

[0057] Step S107: extracting test dimension information of the electrical connector from the test image.

[0058] The test size information refers to the size of the electrical connector in the test image.

[0059] Optionally, the test image includes an axial test image and a radial test image, wherein the axial test image is obtained by photographing from an axial angle of the electrical connector, and the radial test image is obtained by photographing from a radial angle of the electrical connector.

[0060] Exemplarily, the test dimension information includes the radius, horizontal length, vertical length, height, etc. of the electrical connector.

[0061] Step S108: If the difference between the test size information and the standard size information is greater than a preset difference threshold, the production parameters of the electrical connector are updated according to the test size information.

[0062] The standard size information is the size that meets the design standards of the electrical connector. The preset difference threshold is a preset error, and the technician can adjust the specific value of the preset difference threshold according to actual needs.

[0063] When the difference between the test size information and the standard size information is greater than the preset difference threshold, it indicates that the size of the electrical connector is significantly different from the standard size, and after the electrical connector is generated, a significant error occurs in the electrical connector.

[0064] Production parameters include the position of the locating holes, the arrangement of the rectangular array through holes, the cutting size, the cutting angle, the radius / diameter after rounding, the installation position of the clamp assembly, the tightness of the clamp assembly and the size requirements of the clamp assembly.

[0065] For example, please refer to Figure 4 ,The production parameters include the lengths of line segments AB and CD and the lengths of line segments OE and OF in the ,test image.

[0066] Step S109: If the difference between the test size information and the standard size information is not greater than a preset difference threshold, the electrical connector is moved to the finished product area.

[0067] The finished product area is used to place electrical connectors that meet design requirements.

[0068] When the difference between the test size information and the standard size information is not greater than the preset difference threshold, it indicates that the difference between the size of the electrical connector and the standard size is within the error range, and the size of the electrical connector meets the design requirements.

[0069] By adopting the above technical solution, the electrical connector is formed in an integrated manner, eliminating the need for assembly of pins and inner mesh rings, thus reducing the number of production steps. Moreover, the production process of the electrical connector is fully automated, ensuring both production efficiency and dimensional specifications.

[0070] In the following embodiment, when determining that the difference between the test size information and the standard size information is greater than the preset difference threshold, it is also necessary to consider whether the error in the test size information is an accidental error. Therefore, the embodiment of the present application discloses a judgment method for updating production parameters. Figure 5 , the method comprising: Step S501: Determine the test electrical connector corresponding to the test size information.

[0071] The test electrical connector may be one electrical connector or multiple electrical connectors. For example, the test electrical connector refers to a complete electrical connector in the test image. Furthermore, the test electrical connector refers to an electrical connector for which complete size information is obtained in the test image.

[0072] Step S502: determining an electrical connector set according to the test electrical connector.

[0073] Optionally, the electrical connector set is determined based on the order in which the test electrical connectors are arranged on the remaining copper sheet. Exemplarily, after determining the position sequence of the test electrical connector on the remaining copper sheet, the first n electrical connectors of the test electrical connector and the last n electrical connectors of the test electrical connector are determined based on the position sequence, and the first n electrical connectors, the last n electrical connectors, and the test electrical connector are set as the electrical connector set. For example, assuming n is 2 and the test electrical connector is the 8th to 150th electrical connector on the remaining copper sheet, then the first n electrical connectors are the 6th to 7th electrical connectors, and the last n electrical connectors are the 11th to 12th electrical connectors.

[0074] Step S503: Acquire the size information corresponding to the electrical connector set to obtain a size information set.

[0075] The dimensional information set consists of three parts: the first n electrical connectors, the test electrical connector, and the last n electrical connectors. The dimensional information corresponding to the test electrical connector is the test dimensional information. The processing equipment can store the dimensional information of the electrical connectors in a database, so the dimensional information corresponding to the first n electrical connectors can be retrieved from the database. The dimensional information for the last n electrical connectors can be obtained by capturing test images of the last n electrical connectors and completing tests.

[0076] Step S504: Counting the problem size information in the size information set, and the difference between the problem size information and the standard size information is greater than a preset difference threshold.

[0077] Exemplarily, with reference to the standard size information, the problem size information is determined in the size information set so that the difference between the problem size information and the standard size information is greater than a preset difference threshold.

[0078] Step S505: When the number of problem dimension information is greater than the quantity threshold, extract the axial parameters and radial parameters in the test dimension information. The axial parameters are used to represent the dimension parameters of the electrical connector along the axial direction, and the radial parameters are used to represent the dimension parameters of the electrical connector along the radial direction.

[0079] The quantity threshold is a preset empirical value, and technicians can adjust the specific value of the data threshold according to actual needs.

[0080] The electrical connector is cylindrical, the axial parameters are extracted from the axial angle of the electrical connector, and the radial parameters are extracted from the radial angle of the electrical connector. For example, please refer to Figure 4 , the axial parameters are the lengths of the line segments OE and OF, and the radial parameters are the lengths of the line segments AB and CD.

[0081] In other embodiments of the present application, when the number of problem size information is not greater than the number threshold, it means that the difference between the test size information and the standard size information is greater than the preset difference threshold, which is an accidental error and the production parameters may not be updated.

[0082] Step S506: Update the production parameters according to the axial parameters and the radial parameters.

[0083] The process of updating the production parameters according to the axial parameters and the radial parameters can be referred to the description of the subsequent embodiments and will not be repeated here.

[0084] By adopting the above technical solution, the axial parameters and radial parameters are used to update the production parameters only when it is detected that the number of problem size information is greater than the quantity threshold, thereby avoiding the impact of accidental errors in the production process on electrical connectors and ensuring the effectiveness of the production parameter update.

[0085] In the following embodiments, the axial parameters and radial parameters can be used to update the relevant production parameters of the rolling operation to achieve standardization and normalization of the rolling operation. Therefore, the embodiment of the present application discloses a method for updating production parameters. Figure 6 , the method comprising: Step S601: generating an axial shape of the electrical connector according to axial parameters.

[0086] In actual scenarios, the applicant found that the axial shape of the electrical connector is usually circular or elliptical. The axial parameters include transverse length and longitudinal length. The transverse length refers to the length of the transverse line segment passing through the geometric center point of the axial shape, and the longitudinal length refers to the length of the longitudinal line segment passing through the geometric center point of the axial shape. The transverse length and longitudinal length are used to represent the axial shape. If the difference between the transverse length and the longitudinal length is less than the preset length error, it means that the axial shape is circular, and the average of the transverse length and the longitudinal length is taken as the diameter of the circle; if the transverse length is not less than the preset length error, it means that the axial shape is elliptical, and the major axis and minor axis of the ellipse are determined according to the relationship between the transverse length and the longitudinal length and the size.

[0087] Step S602: If the similarity between the axial shape and the standard shape is greater than a preset similarity threshold, the axial circumference of the electrical connector is generated according to the axial parameters and the radial parameters.

[0088] The standard shape is a preset shape. In this application, the standard shape is a circle, and the radius of the standard shape is a preset radius.

[0089] When the axial shape is circular, the radius of the axial shape is obtained to obtain the circumferential radius. The difference between the axial radius and the preset radius is calculated, and the ratio of the difference to the standard radius is calculated to obtain the similarity.

[0090] When the axial shape is an ellipse, the ratio of the minor axis to the major axis of the axial shape is calculated to obtain a first ratio; the mean of the minor axis and the major axis is calculated to obtain the mean axial length; and the ratio of the mean axial length to a preset radius is calculated to obtain a second ratio. The first ratio and the second ratio are weighted to obtain a similarity. The weight values ​​in the weighted calculation are preset, for example, the weight value corresponding to the first ratio is 0.6, and the weight value corresponding to the second ratio is 0.4.

[0091] Furthermore, when the first ratio is greater than a preset first ratio threshold, it indicates that the flatter the ellipse corresponding to the axial shape is, the larger its similarity to the standard shape is. It can be directly considered that the similarity between the axial shape and the standard shape is greater than the preset similarity threshold.

[0092] The preset similarity threshold is a preset empirical value, and technicians can adjust the specific value of the preset similarity threshold according to actual needs. Furthermore, different preset similarity thresholds are set for different axial shapes.

[0093] In other embodiments of the present application, if the similarity between the axial shape and the standard shape is not greater than the preset similarity threshold, it is verified that the size information in the axial test image is normal, and the problem occurs in the radial test image. The applicant has found through multiple tests and studies that in this case, the problem in the production process arises in the link of adding the clamp assembly. For specific details, please refer to the embodiment shown in the figure.

[0094] Step S603: when the difference between the axial circumference and the standard circumference is less than the preset circumference difference, obtaining graphic parameters corresponding to the axial shape.

[0095] The standard circumference refers to the axial circumference of an electrical connector that meets design standards. The preset circumference difference is a preset error value, which technicians can adjust based on actual needs.

[0096] If the axial shape is circular, the graphic parameter refers to the radius. If the axial shape is elliptical, the graphic parameter refers to the major axis length and minor axis length.

[0097] Step S604: Obtain first ideal production parameters corresponding to the curling operation.

[0098] The first ideal production parameter refers to the production parameter of the crimping equipment when producing the electrical connector that meets the design standard. The first ideal production parameter is preset.

[0099] The production parameters of the rolling equipment include pressure parameters, position parameters, and motion parameters. The pressure parameter refers to the pressure value applied to the first intermediate piece. The position parameter refers to the location on the first intermediate piece where the pressure is applied. The motion parameter refers to the dwell time of the pressure applied on the first intermediate piece.

[0100] Step S605: Calculate the first current production parameter corresponding to the curling operation according to the graphic parameters.

[0101] The first current production parameter refers to the production parameter of the rolling equipment during actual production. The content of the first current production parameter can be referred to the description of the first ideal production parameter, which will not be repeated here.

[0102] In actual scenarios, the first current production parameters are retrieved from a preset first production parameter mapping table based on the image parameters. The first production parameter mapping table is used to record the mapping relationship between the image parameters and the first current production parameters. The data in the first production parameter mapping table can be obtained by technicians through repeated experiments and recording.

[0103] Step S606: updating the first current production parameter according to the first ideal production parameter and the first current production parameter.

[0104] For example, the difference between the first ideal production parameter and the first current production parameter is calculated to obtain a parameter difference. The ratio of the parameter difference to a preset value is calculated to obtain a unit parameter difference. With the first ideal production parameter as the target, the first current production parameter is updated according to the unit parameter difference. For example, if the production parameters corresponding to the curling operation include a pressure parameter, and the unit parameter difference is 20, the first current production parameter is a, and the first ideal production parameter is b, the first current production parameter is updated in the order of a+20, a+40, ..., b.

[0105] By adopting the above technical solution, after a large deviation occurs in the axial shape of the electrical connector, the difference between the axial circumference and the standard circumference is calculated. When the aforementioned difference is less than the preset circumference difference, the graphic parameters corresponding to the axial shape are used to generate the first ideal production parameters, and the first current production parameters are updated, thereby realizing automatic calibration of the electrical connector production process and ensuring that the size of the electrical connector meets the design standards.

[0106] In the following embodiments, the axial parameters and radial parameters can be used to update the relevant production parameters of the cutting operation to achieve standardization and normalization of the cutting process. The embodiment of the present application discloses a second method for updating production parameters. Figure 7 , the method comprising: Step S701: When the difference between the axial circumference and the standard circumference is not less than the preset circumference difference, the difference between the axial circumference and the standard circumference is recorded as the circumference difference.

[0107] When the difference between the axial circumference and the standard circumference is not less than the preset circumference difference, it means that the axial circumference of the electrical connector does not meet the design standard. The reason for not meeting the design standard is that the cutting length does not meet the requirements when the copper sheet is cut. Therefore, this embodiment will update the production parameters of the cutting process.

[0108] Step S702: Acquire a second current production parameter corresponding to the cutting process, where the second current production parameter includes a cutting length of the cutting process.

[0109] The second current production parameter refers to the production parameter of the cutting device during actual production.

[0110] Optionally, the sum of the axial circumference and a preset error margin is calculated to obtain the cutting length.

[0111] Step S703: Calculate the sum of the perimeter difference and the cutting length to obtain an updated cutting length.

[0112] The updated cutting length refers to the cutting length after the cutting device is updated.

[0113] Step S704: updating the second current production parameter by updating the cutting length.

[0114] Exemplarily, the updated cutting length is used as the updated cutting length of the cutting device to update the second current production parameter.

[0115] By adopting the above technical solution, when the difference between the axial circumference and the standard circumference is not less than the preset circumference difference, the sum of the circumference difference and the cutting length is calculated to obtain the updated cutting length, and the second current production parameter is used to update it, thereby realizing automatic calibration of the electrical connector production process and ensuring that the size of the electrical connector meets the design standards.

[0116] In the following embodiments, the axial parameters and radial parameters can be used to update the relevant production parameters of the clamp assembly to achieve standardization and normalization of the cutting process. The embodiment of the present application discloses a third method for updating production parameters. Figure 8 , the method comprising: Step S801: If the similarity between the axial shape and the standard shape is not greater than a preset similarity threshold, extracting the clamp size corresponding to the clamp assembly from the radial parameters.

[0117] The clamp size refers to the radial length of the clamp assembly. For example, referring to the figure, the clamp size is the length of line segment AB.

[0118] Step S802: setting the difference between the clamp size and the preset clamp size as the clamp size difference.

[0119] Preset clamp size refers to the size of the clamp assembly in the electrical connector that meets the design standards.

[0120] Step S803: obtaining a third current production parameter corresponding to the clamp assembly, the third current production parameter including a clamp clamping parameter corresponding to the clamp assembly, the clamp clamping parameter including a clamp clamping time and a clamp clamping force value.

[0121] Optionally, the present application adds the clamp assembly to the second middle piece through a clamp device. The clamp device installs the clamp assembly onto the second middle piece and adjusts the tightness of the clamp assembly to tighten the clamp on the second middle piece.

[0122] Furthermore, the clamp device is equipped with a timer and a force sensor. The clamp clamping time can be obtained through the timer, and the clamp clamping force value can be obtained through the force sensor.

[0123] Step S804: determining a third target production parameter in a preset mapping table according to the clamp size difference.

[0124] The third target production parameter refers to the change value of the production parameter corresponding to the clamp equipment.

[0125] The preset mapping table is used to record the mapping relationship between the clamp size difference and the third target production parameter. The data in the preset mapping table can be obtained by technicians through repeated experiments and recording.

[0126] Step S805: updating the third current production parameter according to the third target production parameter.

[0127] Exemplarily, the sum of the third target production parameter and the third current production parameter is calculated to update the third current production parameter.

[0128] By adopting the above technical solution, when the difference between the clamp size and the preset clamp size is greater than the preset clamp size difference, a third target production parameter is determined in the preset mapping table based on the clamp size difference, and the third current production parameter is updated using the third target production parameter. This achieves automatic calibration of the electrical connector production process, ensuring that the dimensions of the electrical connector meet design standards.

[0129] In the following embodiments, after obtaining the test image, the electrical connector in the test image may be deflected or bent, which may affect the reading of the correct production parameters. Therefore, the embodiment of the present application discloses a method for updating the production parameters. Figure 9 , the method comprising: Step S901: Obtain a first deflection angle and a second deflection angle of the electrical connector from a test image, wherein the first deflection angle refers to the angle between the electrical connector and the straight line corresponding to the first end of the copper sheet, and the second deflection angle refers to the angle between the electrical connector and the plane corresponding to the copper sheet.

[0130] For example, the electrical connector in the test image may be deflected or bent, and in this case, the production parameters read from the test image may have a large deviation.

[0131] Step S902: Generate rotational posture information of the electrical connector according to the first deflection angle and the second deflection angle.

[0132] The rotation posture information is used to describe the current posture of the electrical connector. The rotation posture information includes a first deflection angle, a first deflection direction corresponding to the first deflection angle, a second deflection angle, and a second deflection direction corresponding to the second deflection angle.

[0133] Step S903: Correct the axial parameters according to the rotation posture information.

[0134] For example, a posture matrix of the electrical connector is generated based on the rotational posture information. The posture matrix is ​​composed of a rotation matrix, Euler angles, and the position of the electrical connector. The axial parameters are corrected based on the posture matrix so that the corrected axial parameters satisfy a preset standard posture of the electrical connector.

[0135] Step S904: Correct the radial parameters according to the rotation posture information.

[0136] For example, a posture matrix of the electrical connector is generated based on the rotational posture information. The posture matrix is ​​composed of a rotation matrix, Euler angles, and the position of the electrical connector. The radial parameters are corrected based on the posture matrix so that the corrected radial parameters satisfy a preset standard posture of the electrical connector.

[0137] By employing the above technical solution, the first and second deflection angles of the electrical connector are obtained, and rotational posture information of the electrical connector is generated based on the first and second deflection angles. The rotational posture information is used to update the axial and radial parameters, making the axial and radial parameters more accurate, which facilitates subsequent determination of whether the size of the electrical connector is standard.

[0138] In the following embodiment, when the electrical connector in the test image is deflected or bent, the position of the clamp assembly in the electrical connector may be offset by a certain amount. In order to deal with the aforementioned offset, the embodiment of the present application discloses a method for updating the third current production parameter. Figure 10 , the method comprising: Step S1001: Acquire a third current production parameter corresponding to the clamp assembly.

[0139] The third current production parameter includes the clamp clamping parameters corresponding to the clamp assembly. The clamp clamping parameters include the clamp clamping duration and the clamp clamping force. The clamp equipment is equipped with a timer and a force sensor. The clamp clamping duration can be obtained using the timer, and the clamp clamping force can be obtained using the force sensor.

[0140] Step S1002: Calculating posture difference information between the current posture of the electrical connector and the standard posture according to the first deflection angle and the second deflection angle.

[0141] The posture difference information is used to describe the first deflection angle of the current posture of the electrical connector relative to the standard posture, the first deflection direction corresponding to the first deflection angle, the second deflection angle, and the second deflection direction corresponding to the second deflection angle.

[0142] Step S1003: Calculate the clamp displacement deviation based on the posture difference information.

[0143] For example, the clamp displacement deviation corresponding to the posture difference information is retrieved from a preset displacement deviation mapping table, which is obtained by repeated experiments and records by technicians.

[0144] Step S1004: updating the third current production parameter according to the clamp displacement deviation.

[0145] Exemplarily, the clamp displacement parameter in the third current production parameter is updated according to the clamp displacement deviation.

[0146] By adopting the above technical solution, the first deflection angle and the second deflection angle are used to calculate the posture difference information between the current posture of the electrical connector and the standard posture, the clamp displacement deviation is calculated based on the posture difference information, and the third current production parameter is updated based on the clamp displacement deviation, thereby realizing automatic calibration of the electrical connector production process and ensuring that the size of the electrical connector meets the design standards.

[0148] By adopting the above technical solution, the electrical connector is formed in an integrated manner, eliminating the need for assembly of pins and inner mesh rings, thus reducing the number of production steps. Moreover, the production process of the electrical connector is fully automated, ensuring both production efficiency and dimensional specifications.
