Description

Technical Field

[0001] This application relates to the field of machining technologies, and in particular to a welding machine control method, system, storage medium, and intelligent terminal. Background Art

[0002] A welding machine refers to an electrical appliance that provides a power source with certain characteristics for welding. Welding is widely used in various industrial fields, such as aerospace, shipbuilding, automobiles, containers, etc., due to its advantages of being flexible, simple, convenient, firm and reliable, and having the same strength as the base material after welding.

[0003] In related technologies, the welding treatment of pipe fittings often involves the use of a welding machine. QR codes are set on the pipe fittings, and the unique identification codes corresponding to the QR codes have corresponding processing methods in a set database. During the processing of pipe fittings, the staff bound to the welding machine manually scans the QR code so that the welding machine can work according to the processing method corresponding to the pipe fitting, thereby realizing the normal processing of the pipe fitting.

[0004] Regarding the above related technologies, the inventor believes that the QR code on the pipe fitting needs to be manually scanned by the staff, which not only increases the workload of the staff, but also the processing efficiency of the pipe fitting is relatively low and there is still room for improvement. Summary of the Invention

[0005] In order to reduce the workload of the staff while improving the processing efficiency of pipe fittings, this application provides a welding machine control method, system, storage medium, and intelligent terminal.

[0006] In a first aspect, this application provides a welding machine control method, adopting the following technical solution:

[0007] A welding machine control method includes:

[0008] Obtain the pipe fitting storage information of a preset temporary storage area;

[0009] Judge whether the situation corresponding to the pipe fitting storage information is consistent with the preset in-place situation;

[0010] If the situation corresponding to the pipe fitting storage information is inconsistent with the in-place situation, control the preset feeding component to grab the pipe fitting to the temporary storage area;

[0011] If the situation corresponding to the pipe fitting storage information is consistent with the in-place situation, output an in-place signal and control the preset scanning component to scan the QR code on the pipe fitting, and output the QR code information;

[0012] When the QR code information is output, control the preset discharging component to grab the pipe fitting in the temporary storage area and move it to the preset processing area, and control the welding machine to process the pipe fitting according to the QR code information.

[0013] By adopting the above technical solution, the pipe fitting storage information of the temporary storage area for pipe fittings can be obtained first to determine whether there are pipe fittings to be scanned in this area. If there are pipe fittings that need to have their two-dimensional codes scanned, the scanning component is used to scan the two-dimensional code on the pipe fitting to read the two-dimensional code information on the pipe fitting, so that the welding machine can process the pipe fitting according to the content recorded in the two-dimensional code. Using this solution, unmanned operation can be achieved, reducing the workload of the staff and improving the processing efficiency of the pipe fitting.

[0014] Optionally, it further includes a method for scanning the two-dimensional code of the pipe fitting, and this method includes:

[0015] After the in-place signal is output, control the scanning component to move to the preset initial position for operation and output the scanning situation information;

[0016] Judge whether the situation corresponding to the scanning situation information is consistent with the preset scanning completion situation;

[0017] If the situation corresponding to the scanning situation information is consistent with the scanning completion situation, output the two-dimensional code information;

[0018] If the situation corresponding to the scanning situation information is inconsistent with the scanning completion situation, obtain the current pipe fitting image information and judge whether there is a preset two-dimensional code image in the image corresponding to the current pipe fitting image information;

[0019] If there is a two-dimensional code image in the image corresponding to the current pipe fitting image information, output a normal signal and control the scanning component to move to the position where the two-dimensional code is located to scan the two-dimensional code;

[0020] If there is no two-dimensional code image in the image corresponding to the pipe fitting image information, output an abnormal signal.

[0021] By adopting the above technical solution, the scanning component can be moved to the initial position for scanning work, and it is judged whether the two-dimensional code on the pipe fitting at this time is in the position relative to the initial position. If the two-dimensional code is not in this position, there may be a situation where the two-dimensional code printing position is incorrect or the pipe fitting storage is misaligned. At this time, the image of the pipe fitting surface is obtained to determine whether there is a two-dimensional code image. If there is a two-dimensional code image, control the scanning component to move to the two-dimensional code for scanning. If there is no two-dimensional code image, there may be a situation where the two-dimensional code is on the back and cannot be photographed or the two-dimensional code is not printed, etc. At this time, output an abnormal signal to mark this situation for subsequent further judgment of the pipe fitting two-dimensional code.

[0022] Optionally, when the abnormal signal is output, the welding machine control method further includes:

[0023] Control the pipe fitting to rotate along a preset fixed direction with the pipe fitting axis as the rotation axis and obtain the rotation angle information;

[0024] Determine whether the angle value corresponding to the rotation angle information is less than the preset rotation threshold;

[0025] If the angle value corresponding to the rotation angle information is less than the rotation threshold, determine whether there is a normal signal;

[0026] If there is no normal signal, continue to control the rotation of the pipe fitting;

[0027] If there is a normal signal, control the pipe fitting to stop rotating so that the scanning component can perform two-dimensional code scanning;

[0028] If the angle value corresponding to the rotation angle information is not less than the rotation threshold, control the pipe fitting to stop rotating and output a two-dimensional code missing signal.

[0029] By adopting the above technical solution, the pipe fitting can rotate around its axis, and the rotation angle of the pipe fitting is judged to determine whether there is a two-dimensional code on the pipe fitting by continuously judging the two-dimensional code situation during one rotation of the pipe fitting. If a two-dimensional code image is detected during the rotation, it means that there is a two-dimensional code on the pipe fitting, and only need to control the scanning component to move to the two-dimensional code for scanning.

[0030] Optionally, it further includes a method for the scanning component to move to the two-dimensional code, and the method includes:

[0031] Obtain the two-dimensional code position information, the arc moving speed information of the scanning component, and the rotation speed information of the pipe fitting;

[0032] Determine the axial distance information, the circumferential radian information, and the relative direction according to the two-dimensional code position information and the preset scanning position corresponding to the initial position on the pipe fitting;

[0033] Judge whether the distance value corresponding to the axial distance information is zero;

[0034] If the distance value corresponding to the axial distance information is not zero, output a misalignment signal;

[0035] If the distance value corresponding to the axial distance information is zero, determine the arc time information according to the circumferential radian information, the arc moving speed information, and the rotation speed information;

[0036] Control the pipe fitting to rotate in a fixed direction, and control the scanning component to move in the opposite direction along the fixed direction for the time corresponding to the arc time information so that the scanning component moves to the two-dimensional code.

[0037] By adopting the above technical solution, when the current position of the two-dimensional code and the preset position are on the same circumferential direction of the pipe fitting, the scanning component and the pipe fitting can be controlled to rotate synchronously, thereby reducing the time for the scanning component to move to the two-dimensional code and improving the operation efficiency.

[0038] Optionally, when the misalignment signal is output, the welding machine control method further includes:

[0039] Obtaining the linear movement speed information of the scanning component;

[0040] Determining the linear time information based on the axial distance information and the linear movement speed information;

[0041] Judging whether the duration corresponding to the linear time information is greater than the preset time threshold;

[0042] If the duration corresponding to the linear time information is greater than the time threshold, controlling the scanning component to move in the opposite direction for the duration corresponding to the linear time information, and controlling the pipe fitting to rotate in the fixed direction for the time threshold duration;

[0043] If the duration corresponding to the linear time information is not greater than the time threshold, determining the first radian information of the rotation of the pipe fitting according to the linear time information;

[0044] Determining the second radian information based on the circumferential radian information and the first radian information, and determining the secondary time information based on the second radian information, the arc movement speed information, and the rotation speed information;

[0045] Calculating the sum of the linear time information and the secondary time information to determine the total time information, controlling the pipe fitting to rotate in the fixed direction for the duration corresponding to the total time information, and controlling the scanning component to move in the opposite direction for the duration corresponding to the linear time information and then controlling the scanning component to move in the opposite fixed direction for the duration corresponding to the secondary time information.

[0046] By adopting the above technical solution, when the current position of the two-dimensional code is not on the same circumferential direction of the pipe fitting as the preset position, the scanning component and the pipe fitting can be moved synchronously to reduce the time for the scanning component to move to the two-dimensional code, and improve the operation efficiency.

[0047] Optionally, after the two-dimensional code missing signal is output, the welding machine control method further includes:

[0048] Controlling the blanking component to grab the pipe fitting in the temporary storage area and move it to the preset waste area, and counting the two-dimensional code missing signal to determine the missing quantity information;

[0049] Counting according to the in-place signal to determine the in-place quantity information, and calculating according to the in-place quantity information and the missing quantity information to determine the product missing rate;

[0050] Judging whether the product missing rate is greater than the preset defect threshold;

[0051] If the product missing rate is not greater than the preset defect threshold, outputting a batch qualified signal;

[0052] If the product missing rate is greater than the preset defect threshold, an abnormal batch signal is output.

[0053] By adopting the above technical solution, the blanking component can move the pipe fittings missing the two-dimensional code to the waste area for storage, so as to facilitate the subsequent processing of the pipe fittings by the staff. At the same time, the qualified rate of the pipe fitting products in this batch can be judged according to the number of pipe fittings missing the two-dimensional code, so that the staff can know the quality of the products in this batch.

[0054] Optionally, it further includes:

[0055] When the abnormal batch signal is output, judge whether the numerical value corresponding to the in-place quantity information is greater than the preset reference threshold;

[0056] If the numerical value corresponding to the in-place quantity information is not greater than the reference threshold, a pending batch signal is output;

[0057] If the numerical value corresponding to the in-place quantity information is greater than the reference threshold, an unqualified batch signal is output.

[0058] By adopting the above technical solution, when the product missing rate during the inspection of this batch is relatively high, the number of inspected pipe fittings can be judged to reduce the inspection result of unqualified product quality due to a small total number of inspected pipe fittings but a high product missing rate.

[0059] In a second aspect, the present application provides a welding machine control system, adopting the following technical solution:

[0060] A welding machine control system includes:

[0061] An acquisition module for acquiring the pipe fitting storage information of the preset temporary storage area;

[0062] A processing module is connected to the acquisition module and the judgment module, and is used for storing and processing information;

[0063] A judgment module for judging whether the situation corresponding to the pipe fitting storage information is consistent with the preset in-place situation;

[0064] If the judgment module judges that the situation corresponding to the pipe fitting storage information is inconsistent with the in-place situation, the processing module controls the preset feeding component to grab the pipe fittings to the temporary storage area;

[0065] If the judgment module judges that the situation corresponding to the pipe fitting storage information is consistent with the in-place situation, the processing module outputs an in-place signal and controls the preset scanning component to scan the two-dimensional code on the pipe fittings, and outputs the two-dimensional code information;

[0066] When the processing module outputs the two-dimensional code information, it controls the preset blanking component to grab the pipe fittings in the temporary storage area and move them to the preset processing area, and controls the welding machine to process the pipe fittings according to the two-dimensional code information.

[0067] By adopting the above technical solution, the acquisition module can first obtain the pipe fitting storage information of the temporary storage area for storing pipe fittings, so that the judgment module can judge whether there are pipe fittings to be scanned in this area. If the judgment module judges that there are pipe fittings that need to be scanned with a two-dimensional code, the processing module can control the scanning component to scan the two-dimensional code on the pipe fittings to realize the reading of the two-dimensional code information on the pipe fittings, so that the welding machine can process the pipe fittings according to the content recorded in the two-dimensional code. Using this solution can realize unmanned operation, reduce the workload of staff and improve the processing efficiency of pipe fittings.

[0068] In a third aspect, the present application provides an intelligent terminal, adopting the following technical solution:

[0069] An intelligent terminal includes a memory and a processor, and a computer program capable of being loaded and executed by the processor for any one of the above welding machine control methods is stored on the memory.

[0070] By adopting the above technical solution, through the use of the intelligent terminal, the pipe fitting storage information of the temporary storage area for storing pipe fittings can be obtained first to judge whether there are pipe fittings to be scanned in this area. If there are pipe fittings that need to be scanned with a two-dimensional code, the scanning component is used to scan the two-dimensional code on the pipe fittings to realize the reading of the two-dimensional code information on the pipe fittings, so that the welding machine can process the pipe fittings according to the content recorded in the two-dimensional code. Using this solution can realize unmanned operation, reduce the workload of staff and improve the processing efficiency of pipe fittings.

[0071] In a fourth aspect, the present application provides a computer storage medium, which can store corresponding programs and has the characteristics of reducing the workload of staff while improving the processing efficiency of pipe fittings, adopting the following technical solution:

[0072] A computer-readable storage medium stores a computer program capable of being loaded and executed by the processor for any one of the above welding machine control methods.

[0073] By adopting the above technical solution, there is a computer program of the welding machine control method in the storage medium. The pipe fitting storage information of the temporary storage area for storing pipe fittings can be obtained first to judge whether there are pipe fittings to be scanned in this area. If there are pipe fittings that need to be scanned with a two-dimensional code, the scanning component is used to scan the two-dimensional code on the pipe fittings to realize the reading of the two-dimensional code information on the pipe fittings, so that the welding machine can process the pipe fittings according to the content recorded in the two-dimensional code. Using this solution can realize unmanned operation, reduce the workload of staff and improve the processing efficiency of pipe fittings.

[0074] In summary, the present application includes at least one of the following beneficial technical effects:

[0075] 1. Automatically load, scan, and unload pipe fittings to achieve unmanned operation, reducing the workload of staff while improving the processing efficiency of pipe fittings;

[0076] 2. Scan pipe fittings with printing errors in the QR code position to reduce the situation of pipe fittings resuming work, further improving the operation efficiency;

[0077] 3. Detect the product quality of pipe fittings in a batch, enabling staff to conveniently know the product quality of this batch of pipe fittings. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] In order to make the objectives, technical solutions, and advantages of the present application clearer, the following further elaborates on the present application in conjunction with the attached Figure 1-7 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0086] The following further describes the embodiments of the present invention in detail with reference to the drawings of the specification.

[0087] An embodiment of the present application discloses a welding machine control method. When processing pipe fittings, it can achieve automatic loading, scanning, and unloading of pipe fittings to achieve unmanned operation, reduce the workload of staff, and improve the operation efficiency during pipe fitting processing.

[0088] Referring to Figure 1 , the method flow of welding machine control includes the following steps:

[0089] Step S100: Obtain the pipe fitting storage information of the preset temporary storage area.

[0090] The temporary storage area is an area set for placing pipe fittings to scan the pipe fittings. The situation corresponding to the pipe fitting storage information is whether there are pipe fittings placed on the temporary storage area, which can be achieved by placing a pressure sensor at the bottom of the temporary storage area, or by setting opposed infrared sensors on both sides of the position where the pipe fittings are placed. The specific method is set by the staff according to the actual situation and will not be elaborated.

[0091] Step S101: Determine whether the situation corresponding to the pipe fitting storage information is consistent with the preset in-place situation.

[0092] The in-place situation is that there are pipe fittings placed on the temporary storage area, which is set by the staff. The purpose of the judgment is to know whether there are pipe fittings placed on the temporary storage area in the current situation, so as to facilitate the subsequent QR code scanning of the pipe fittings.

[0093] Step S1011: If the situation corresponding to the pipe fitting storage information is inconsistent with the in-place situation, control the preset feeding component to grab the pipe fitting to the temporary storage area.

[0094] When the situation corresponding to the pipe fitting storage information is inconsistent with the in-place situation, it means that there are no pipe fittings stored in the temporary storage area at this time, and the QR code scanning work of the pipe fittings cannot be carried out at this time. Therefore, in order to ensure the normal processing of the pipe fittings, the feeding component is used to grab the pipe fitting into the temporary storage area, so as to facilitate the subsequent QR code scanning of the pipe fitting. The feeding component can be the cooperation of an electric gripper and a linear module, so that it can realize the grasping, moving and putting down of the pipe fitting. The specific structure is set by the staff according to the actual situation and will not be elaborated.

[0095] Step S1012: If the situation corresponding to the pipe fitting storage information is consistent with the in-place situation, output an in-place signal and control the preset scanning component to scan the QR code on the pipe fitting and output the QR code information.

[0096] When the situation corresponding to the pipe fitting storage information is consistent with the in-place situation, it means that there are pipe fittings stored in the temporary storage area at this time, and the QR code scanning work of the pipe fittings can be carried out. Output an in-place signal to identify this situation, so that the staff can know that the pipe fitting is in a scannable state; at this time, use the scanning component for scanning the QR code to scan the QR code on the pipe fitting, and output the QR code information according to the information recorded in the QR code. The QR code information contains the processing method of the pipe fitting. The scanning component is a conventional device capable of QR code scanning, which is set by the staff according to the actual situation and will not be elaborated.

[0097] Step S102: When outputting the two-dimensional code information, control the preset blanking component to grab the pipe fitting in the temporary storage area and move it to the preset processing area, and control the welding machine to process the pipe fitting according to the two-dimensional code information.

[0098] When the two-dimensional code information is output, it indicates that the pipe fitting can be processed according to the processing method recorded in the two-dimensional code information. At this time, use the blanking component to grab the pipe fitting and move it to the processing area so that the welding machine can process the pipe fitting. Among them, the processing area is an area set in advance for pipe fitting processing. The structure of the blanking component is the same as that of the feeding component, and the feeding component and the blanking component can be used alternately. That is, when one component moves the pipe fitting to the processing area, the other component moves a new pipe fitting to the temporary storage area. At this time, the component that has placed the pipe fitting in the processing area can move to the pipe fitting picking place to grab the next pipe fitting, thus shortening the total time of feeding, scanning, and processing the same number of pipe fittings and improving work efficiency.

[0099] Refer to Figure 2 , and it also includes a method for scanning the two-dimensional code of the pipe fitting. This method includes:

[0100] Step S200: After the in-place signal is output, control the scanning component to move to the preset initial position for operation and output the scanning situation information.

[0101] Among the qualified pipe fittings, when the pipe fitting is placed in the temporary storage area, the position where the two-dimensional code is located should be opposite to the initial position, that is, when the scanning component moves to the initial position for operation, it can scan the two-dimensional code. The setting of the initial position is set by the staff according to the printing position of the two-dimensional code, which will not be elaborated. The situation corresponding to the scanning situation information is the scanning situation when the scanning component is in the initial position, that is, whether the two-dimensional code is scanned.

[0102] Step S201: Judge whether the situation corresponding to the scanning situation information is consistent with the preset scanning completion situation.

[0103] The scanning completion situation is the scanning situation when the scanning component successfully scans the two-dimensional code. The purpose of the judgment is to know whether the scanning component scans the two-dimensional code at this time for subsequent control.

[0104] Step S2011: If the situation corresponding to the scanning situation information is consistent with the scanning completion situation, output the two-dimensional code information.

[0105] When the situation corresponding to the scanning situation information is consistent with the scanning completion situation, it indicates that the scanning component scans the two-dimensional code on the pipe fitting at this time, and output the two-dimensional code information for subsequent processing of the pipe fitting.

[0106] Step S2012: If the situation corresponding to the scanning situation information is inconsistent with the scanning completion situation, obtain the current pipe fitting image information, and determine whether a preset two-dimensional code image exists in the image corresponding to the current pipe fitting image information.

[0107] When the situation corresponding to the scanning situation information is inconsistent with the scanning completion situation, it indicates that the two-dimensional code has not been scanned at the initial position of the scanning component, and there may be a situation where the printing position of the two-dimensional code is incorrect or not printed; the image corresponding to the current pipe fitting image information is an image of one side of the pipe fitting, which is obtained through the camera component, which is a conventional technical means for those skilled in the art and will not be elaborated; the two-dimensional code image is a rough image of the two-dimensional code set in advance, and the purpose of the judgment is to know whether the two-dimensional code is detected in the current placement state of the pipe fitting, so as to facilitate subsequent further operations.

[0108] Step S20121: If a two-dimensional code image exists in the image corresponding to the current pipe fitting image information, output a normal signal and control the scanning component to move to the position where the two-dimensional code is located to scan the two-dimensional code.

[0109] When a two-dimensional code image exists in the image corresponding to the current pipe fitting image information, it indicates that there is a two-dimensional code on the pipe fitting but the printing position of the two-dimensional code is incorrect. At this time, output a normal signal to identify and record this situation, and control the scanning component to move to the position where the two-dimensional code is located to scan the two-dimensional code. The position where the two-dimensional code is located is the position of the center point of the two-dimensional code, which can be obtained by establishing a coordinate system on the pipe fitting, which is a conventional technical means for those skilled in the art and will not be elaborated.

[0110] Step S20122: If no two-dimensional code image exists in the image corresponding to the pipe fitting image information, output an abnormal signal.

[0111] When no two-dimensional code image exists in the image corresponding to the pipe fitting image information, it indicates that there is no two-dimensional code image in the obtained pipe fitting image at this time, that is, there may be a two-dimensional code but it is on the back side of the image detection, or there may be no two-dimensional code. Output an abnormal signal to record this situation, so as to facilitate subsequent further identification and judgment of the pipe fitting two-dimensional code.

[0112] Refer to Figure 3 , when the abnormal signal is output, the welding machine control method further includes:

[0113] Step S300: Control the pipe fitting to rotate along a preset fixed direction with the pipe fitting axis as the rotation axis, and obtain the rotation angle information.

[0114] The fixed direction is clockwise or counterclockwise, which is set by the staff according to the actual situation and will not be elaborated; control the pipe fitting to rotate along the axis of the pipe fitting so that the images on the surface of the pipe fitting can all be collected. The rotation of the pipe fitting can be achieved by placing a component that drives the rotation of the pipe fitting in the temporary placement area, which is a conventional technical means for those skilled in the art and will not be elaborated; at the same time, during the rotation of the pipe fitting, the angle of the pipe fitting is obtained to monitor the rotation situation of the pipe fitting, and record the information of the rotation angle of the pipe fitting, that is, the rotation angle information. This angle can be obtained through an angle sensor, which is a conventional technical means for those skilled in the art and will not be elaborated.

[0115] Step S301: Determine whether the angle value corresponding to the rotation angle information is less than the preset rotation threshold.

[0116] The rotation threshold is the minimum rotation angle of the pipe fitting to ensure that the images on the surface of the pipe fitting can all be collected. For example, if the arc of the pipe fitting that can be detected during image detection is 60°, then the rotation threshold is 360° - 60° = 300°. The staff adjusts the rotation threshold according to the actual image capture device and will not be elaborated; the purpose of the determination is to know whether all surfaces of the pipe fitting have been subjected to image detection, which is convenient for further judgment of the situation of the pipe fitting.

[0117] Step S3011: If the angle value corresponding to the rotation angle information is less than the rotation threshold, then determine whether there is a normal signal.

[0118] When the angle value corresponding to the rotation angle information is less than the rotation threshold, it means that the surface image of the pipe fitting has not been fully collected at this time. The purpose of the determination in this case is to know whether the QR code image has been collected, so as to judge whether there is a QR code on the pipe fitting.

[0119] Step S30111: If there is no normal signal, continue to control the rotation of the pipe fitting.

[0120] When there is no normal signal, it means that the QR code image has not been collected at this time. At this time, control the pipe fitting to continue to rotate to continue to collect and analyze the QR code situation.

[0121] Step S30112: If there is a normal signal, control the pipe fitting to stop rotating so that the scanning component can perform QR code scanning.

[0122] When there is a normal signal, it means that the QR code image has been collected at this time. At this time, only need to control the scanning component to scan the QR code so that the pipe fitting can be processed normally subsequently.

[0123] Step S3012: If the angle value corresponding to the rotation angle information is not less than the rotation threshold, control the pipe fitting to stop rotating and output a QR code missing signal.

[0124] When the angle value corresponding to the rotation angle information is not less than the rotation threshold, it indicates that the surface images of the pipe fitting have all been collected, but the QR code image has still not been collected, that is, it indicates that the pipe fitting is not printed with a QR code. At this time, the pipe fitting is controlled to stop rotating for the processing of the next step, and at the same time, a QR code missing signal is output to identify this situation, so as to facilitate the subsequent processing of this situation.

[0125] Refer to Figure 4 , and also includes a method for moving the scanning component to the position of the QR code. This method includes:

[0126] Step S400: Obtain the QR code position information, the arc moving speed information of the scanning component, and the rotation speed information of the pipe fitting.

[0127] The position corresponding to the QR code position information is the position of the center point of the QR code, which can be obtained by establishing a coordinate system for the pipe fitting; the speed value corresponding to the arc moving speed information is the rotation speed when the scanning component rotates with the axis of the pipe fitting as the rotation axis, and the speed value corresponding to the rotation speed information is the speed value when the pipe fitting rotates. Both speed values are set by the staff according to the actual situation and will not be elaborated.

[0128] Step S401: Determine the axial distance information, the circumferential radian information, and the relative direction according to the QR code position information and the preset scanning position corresponding to the initial position on the pipe fitting.

[0129] The scanning position is the position where the QR code is located when the pipe fitting is normally printed with the QR code. According to the QR code position information and the scanning position, the distance along the circumferential direction and the axial distance of the two can be determined. The distance value corresponding to the axial distance information is the distance between the scanning position and the current position of the QR code in the axial direction of the pipe fitting, the radian value corresponding to the circumferential radian information is the distance between the scanning position and the current position of the QR code in the circumferential direction of the pipe fitting, and the relative direction is the direction from the scanning position to the current position of the QR code in the axial direction.

[0130] Step S402: Determine whether the distance value corresponding to the axial distance information is zero.

[0131] The purpose of the judgment is to know whether the QR code position and the scanning position are on the same circumferential side wall of the pipe fitting, so as to know whether the scanning component needs to move along the axial direction of the pipe fitting.

[0132] Step S4021: If the distance value corresponding to the axial distance information is not zero, then output a misalignment signal.

[0133] When the distance value corresponding to the axial distance information is not zero, it indicates that at this time, the QR code position and the scanning position are not on the same circumferential side wall of the pipe fitting, that is, it is necessary to move the scanning component along the axial direction of the pipe fitting, and output a misalignment signal to identify this situation, so as to facilitate the subsequent control of the movement of the scanning component.

[0134] Step S4022: If the distance value corresponding to the axial distance information is zero, determine the arc time information according to the circumferential radian information, the arc movement speed information, and the rotation speed information.

[0135] When the distance value corresponding to the axial distance information is zero, it indicates that at this time, the scanning component can move to the two-dimensional code for scanning without moving along the axial direction of the pipe fitting. The duration corresponding to the arc time information is the duration of the rotation of the scanning component and the pipe fitting. The calculation formula is , where is the duration corresponding to the arc time information, is the radian value corresponding to the circumferential radian information, is the speed value corresponding to the arc movement speed information, is the speed value corresponding to the rotation speed information.

[0136] Step S403: Control the pipe fitting to rotate in a fixed direction and the scanning component to move in the opposite direction of the fixed direction for the time corresponding to the arc time information, so that the scanning component moves to the two-dimensional code position.

[0137] Controlling the scanning component to move in the opposite direction of the fixed direction enables relative movement between the scanning component and the pipe fitting, thereby shortening the time for the scanning component to move to the two-dimensional code position and improving the efficiency during the scanning operation.

[0138] Refer to Figure 5 , when a misalignment signal is output, the welding machine control method further includes:

[0139] Step S500: Obtain the linear movement speed information of the scanning component.

[0140] When a misalignment signal is output, it indicates that the position of the two-dimensional code at this time and the scanning position are not on the same circumferential side wall of the pipe fitting, and the scanning component needs to move along the axial direction of the pipe fitting to move the scanning component to the two-dimensional code position; the speed value corresponding to the linear movement speed information is the speed value of the scanning component moving along the axial direction of the pipe fitting, which is set by the staff according to the actual situation and will not be elaborated here.

[0141] Step S501: Determine the linear time information according to the axial distance information and the linear movement speed information.

[0142] The duration corresponding to the linear time information is the time required for the scanning component to move along the axial direction of the pipe fitting, which is obtained by dividing the distance corresponding to the axial distance information by the speed value corresponding to the linear movement speed information.

[0143] Step S502: Determine whether the duration corresponding to the linear time information is greater than the preset time threshold.

[0144] The time threshold is the time required for the position where the QR code is detected to rotate to the coaxial side wall position with the scanning position. The purpose of the judgment is to know whether the QR code can move to the relative position for the scanning component to perform the scanning operation when the scanning component moves to the circumferential direction where the QR code is located.

[0145] Step S5021: If the duration corresponding to the linear time information is greater than the time threshold, control the scanning component to move in the relative direction for the duration corresponding to the linear time information, and control the pipe fitting to rotate in the fixed direction for the duration of the time threshold.

[0146] When the duration corresponding to the linear time information is greater than the time threshold, it indicates that during the movement of the scanning component along the axis, the pipe fitting can move to the corresponding position. At this time, control the scanning component to move in the relative direction for the duration corresponding to the linear time information, and control the pipe fitting to rotate in the fixed direction for the duration of the time threshold, so as to enable the scanning component to move to the QR code quickly and realize the normal scanning of the QR code.

[0147] Step S5022: If the duration corresponding to the linear time information is not greater than the time threshold, determine the first radian information of the rotation of the pipe fitting according to the linear time information.

[0148] When the duration corresponding to the linear time information is not greater than the time threshold, it indicates that after the movement of the scanning component along the axis is completed, the pipe fitting has not moved to the position of the coaxial side wall with the scanning position. At this time, the scanning component can be controlled to rotate to further reduce the time for the scanning component to move to the QR code; the radian value corresponding to the first radian information is the radian of the rotation of the pipe fitting under the duration corresponding to the linear time information, so as to facilitate the further control of the pipe fitting and the scanning component in the future.

[0149] Step S503: Determine the second radian information according to the circumferential radian information and the first radian information, and determine the secondary time information according to the second radian information, the arc movement speed information and the rotation speed information.

[0150] The radian value corresponding to the second radian information is the difference radian between the current position of the QR code and the position to which it needs to move, which is the difference between the radian value corresponding to the circumferential radian information and the radian value corresponding to the first radian information. The duration corresponding to the secondary time information is the duration that the scanning component and the pipe fitting need to move. The calculation formula is , where is the duration corresponding to the secondary time information, is the radian value corresponding to the second radian information.

[0151] Step S504: Calculate the sum of the linear time information and the quadratic time information to determine the total time information, control the pipe fitting to rotate in a fixed direction for a duration corresponding to the total time information, and control the scanning component to move in the opposite direction for a duration corresponding to the linear time information and then control the scanning component to move in the opposite direction of the fixed direction for a duration corresponding to the quadratic time information.

[0152] The duration corresponding to the total time information is the sum of the duration corresponding to the linear time information and the duration corresponding to the quadratic time information, which is obtained by conventional addition operations and will not be elaborated; the pipe fitting and the scanning component are controlled respectively according to the duration corresponding to the linear time information and the duration corresponding to the quadratic time information, so that the scanning component can move to the two-dimensional code quickly, reducing the time for the scanning component to move to the two-dimensional code and improving the operation efficiency.

[0153] Refer to Figure 6 , after the two-dimensional code missing signal is output, the welding machine control method further includes:

[0154] Step S600: Control the blanking component to grab the pipe fitting in the temporary storage area and move it to the preset waste area, and count the two-dimensional code missing signal to determine the missing quantity information.

[0155] When the two-dimensional code missing signal is output, it indicates that the two-dimensional code is not printed on the pipe fitting. At this time, the pipe fitting cannot be processed. Control the blanking component to grab the pipe fitting to the waste area to collect the pipe fitting, which is convenient for the staff to process this type of pipe fitting. The waste area is a position set by the staff according to the actual situation. In this application, the waste area can be set between the processing area and the temporary storage area, so that after the blanking component places the unqualified pipe fitting in the waste area, it can move to the pipe fitting storage point in time to pick up new pipe fittings; the numerical value corresponding to the missing quantity information is the total number of two-dimensional code missing signals, that is, the total number of pipe fittings without printed two-dimensional codes. Obtaining the missing quantity information by counting is a conventional technical means for those skilled in the art and will not be elaborated.

[0156] Step S601: Count according to the in-place signal to determine the in-place quantity information, and calculate according to the in-place quantity information and the missing quantity information to determine the product missing rate.

[0157] The numerical value corresponding to the in-place quantity information is the total number of in-place signals, that is, the total number of pipe fitting scans. Obtaining the in-place quantity information by counting is a conventional technical means for those skilled in the art and will not be elaborated; the product missing rate is the probability of the two-dimensional code missing situation in this batch of products, and the calculation formula is , where is the product missing rate, is the numerical value corresponding to the missing quantity information, The quantity value corresponding to the in-place quantity information.

[0158] Step S602: Determine whether the product missing rate is greater than a preset defect threshold.

[0159] The defect threshold is the maximum product missing rate allowed for each batch of products. The purpose of the determination is to find out whether the product missing rate of this batch of products is too high, so as to determine whether this batch of products is qualified.

[0160] Step S6021: If the product missing rate is not greater than the preset defect threshold, output a batch qualified signal.

[0161] When the product missing rate is not greater than the preset defect threshold, it means that the product qualification rate of this batch of products meets the requirements. Output a batch qualified signal so that the staff can know this situation.

[0162] Step S6022: If the product missing rate is greater than the preset defect threshold, output a batch abnormal signal.

[0163] When the product missing rate is greater than the preset defect threshold, it means that the product qualification rate of this batch of products may not meet the requirements. Output a batch abnormal signal for further inspection of the products.

[0164] Step S603: When a batch abnormal signal is output, determine whether the quantity value corresponding to the in-place quantity information is greater than a preset reference threshold.

[0165] When a batch abnormal signal is output, it is possible that the product missing rate is high due to the small number of scanned pipe fittings. That is, when starting to scan 2 pipe fittings, 1 pipe fitting has no QR code printed. At this time, the product missing rate is as high as 50%. To reduce the occurrence of this situation, the use of a reference threshold is introduced. The reference threshold is the set minimum scanned quantity value of the pipe fittings. The purpose of the determination is to find out whether the quantity of the currently scanned pipe fittings exceeds this reference threshold, so as to reduce the situation that the batch quality inspection is inaccurate due to too few pipe fittings being detected.

[0166] Step S6031: If the quantity value corresponding to the in-place quantity information is not greater than the reference threshold, output a batch pending signal.

[0167] When the quantity value corresponding to the in-place quantity information is not greater than the reference threshold, it means that the currently measured product missing rate cannot represent the overall quality of this batch of products. Output a batch pending signal to record this situation so that the staff can know this situation and pay more attention to the inspection of this batch of products.

[0168] Step S6032: If the quantity value corresponding to the in-place quantity information is greater than the reference threshold, output a batch unqualified signal.

[0169] When the quantity value corresponding to the in-place quantity information is greater than the reference threshold, it indicates that the product missing rate measured at this time can represent the overall quality of the products in this batch. An out-of-batch non-conformance signal is output so that the staff can be informed of this situation, facilitating the staff to handle this situation in a timely manner.
