Referring to fig. 1, a method flow of welder management and control includes the following steps:
step S100: and acquiring the pipe storage information of the preset temporary storage area.
The temporary placement area is an area which is used for placing the pipe fitting to scan the pipe fitting, the condition corresponding to the information stored in the pipe fitting is the condition of whether the pipe fitting is placed on the temporary placement area or not, the pressure sensor can be placed at the bottom of the temporary placement area to achieve the condition, or the correlation infrared sensors are arranged on two sides of the position where the pipe fitting is placed to achieve the condition, the specific method is set by a worker according to the actual condition, and the detailed description is omitted.
Step S101: and judging whether the condition corresponding to the pipe storage information is consistent with the preset in-place condition.
The condition of targetting in place places the condition of pipe fitting for temporarily putting on the region, is set for by the staff, and the purpose of judgement is whether to have the pipe fitting to lay in order to learn temporarily putting the region under the current situation to follow-up carry out the two-dimensional code scanning to the pipe fitting.
Step S1011: and if the condition corresponding to the pipe storage information is inconsistent with the in-place condition, controlling the preset feeding assembly to grab the pipe to the temporary placement area.
When the condition that the information corresponds was deposited to the pipe fitting and the condition of targetting in place inconsistent, it does not have the pipe fitting to deposit to explain this moment temporarily to put the region, can't carry out two-dimensional code scanning work to the pipe fitting this moment, consequently in order to guarantee the normal processing of pipe fitting, utilize the material loading subassembly in order to snatch the pipe fitting to temporarily putting in the region, so that follow-up carries out the two-dimensional code scanning to the pipe fitting, the material loading subassembly can be the cooperation of electric clamping jaw and sharp module, make it can realize snatching of pipe fitting, remove and transfer, concrete structure is set up by the staff according to actual conditions, do not describe any more.
Step S1012: if the corresponding condition of the pipe storage information is consistent with the in-place condition, outputting an in-place signal and controlling a preset scanning assembly to scan the two-dimensional code on the pipe, and outputting two-dimensional code information.
When the condition corresponding to the pipe storage information is consistent with the in-place condition, the condition shows that the pipe is stored in the temporary storage area at the moment, the scanning work of the two-dimensional code of the pipe can be carried out, and the in-place signal is output to mark the condition, so that a worker can know that the pipe is in a scannable state; at this moment, the scanning assembly for scanning the two-dimensional code is utilized to scan the two-dimensional code on the pipe fitting, the two-dimensional code information is output according to the information recorded in the two-dimensional code, the two-dimensional code information comprises a processing method of the pipe fitting, the scanning assembly is conventional equipment capable of being used for scanning the two-dimensional code, and the scanning assembly is set by a worker according to actual conditions without repeated description.
Step S102: and when the two-dimension code information is output, the preset blanking assembly is controlled to grab the pipe fitting in the temporary placement area and move to the preset processing area, and the welding machine is controlled to process the pipe fitting according to the two-dimension code information.
When the two-dimension code information is output, the pipe fitting can be processed according to the processing method recorded in the two-dimension code information, at the moment, the blanking assembly is used for grabbing the pipe fitting to move into a processing area, so that the welding machine can process the pipe fitting, the processing area is an area which is set in advance and used for processing the pipe fitting, the structure of the blanking assembly is consistent with that of the feeding assembly, the feeding assembly and the blanking assembly can be used alternately, namely when one assembly moves the pipe fitting into the processing area, the other assembly moves a new pipe fitting into a temporary placing area, at the moment, the assembly which places the pipe fitting into the processing area can move to the pipe fitting taking place to grab the next pipe fitting, so that the total time of feeding, scanning and processing of the pipe fittings with the same number is shortened, and the working efficiency is improved.
Referring to fig. 2, a method for scanning a two-dimensional code of a pipe is also included, the method comprising:
step S200: and after the in-place signal is output, the scanning assembly is controlled to move to a preset initial position for operation, and scanning condition information is output.
In qualified pipe fitting, when the pipe fitting was laid in the region of temporarily putting, the position that the two-dimensional code was located should be relative with initial position, can scan the two-dimensional code promptly when the scanning subassembly moved to initial position operation, and the setting of initial position is set for by the staff according to two-dimensional code printing position, does not do not need to be repeated, and the condition that scanning condition information corresponds is the scanning condition when the scanning subassembly is in initial position, has whether scanned the two-dimensional code promptly.
Step S201: and judging whether the condition corresponding to the scanning condition information is consistent with the preset scanning completion condition.
The scanning completion condition is the scanning condition when the scanning component successfully scans the two-dimensional code, and the purpose of judgment is to know whether the scanning component scans the two-dimensional code at the moment so as to facilitate subsequent control.
Step S2011: and if the condition corresponding to the scanning condition information is consistent with the scanning completion condition, outputting the two-dimensional code information.
When the condition corresponding to the scanning condition information is consistent with the scanning completion condition, the scanning assembly is indicated to have the two-dimensional code scanned on the pipe fitting, and the two-dimensional code information is output to be used for subsequent processing of the pipe fitting.
Step S2012: and if the condition corresponding to the scanning condition information is inconsistent with the scanning completion condition, acquiring the current pipe image information, and judging whether a preset two-dimensional code image exists in the image corresponding to the current pipe image information.
When the condition corresponding to the scanning condition information is inconsistent with the scanning completion condition, it is indicated that the scanning assembly does not scan the two-dimensional code at the initial position, and the condition that the printing position of the two-dimensional code is wrong or not printed may exist; the image corresponding to the current pipe fitting image information is an image of one side of the pipe fitting and is obtained through a camera shooting assembly, which is a conventional technical means of a person skilled in the art and is not described in detail; the two-dimensional code image is a two-dimensional code approximate image which is set in advance, and the purpose of judgment is to know whether the two-dimensional code is detected in the current placement state of the pipe fitting or not so as to facilitate subsequent further operation.
Step S20121: if the two-dimension code image exists in the image corresponding to the current pipe fitting image information, outputting a normal signal and controlling the scanning assembly to move to the position where the two-dimension code is located to scan the two-dimension code.
When a two-dimensional code image exists in an image corresponding to the current pipe image information, it is indicated that a two-dimensional code exists on the pipe but the position where the two-dimensional code is printed is wrong, at this moment, a normal signal is output to identify and record the situation, so that the scanning assembly is controlled 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, and the two-dimensional code can be obtained by establishing a coordinate system on the pipe.
Step S20122: and if the two-dimensional code image does not exist in the image corresponding to the pipe fitting image information, outputting an abnormal signal.
When the two-dimensional code image does not exist in the image corresponding to the pipe fitting image information, the two-dimensional code image does not exist in the pipe fitting image obtained at the moment, namely the two-dimensional code may exist but be positioned on the back side of the image detection, and the two-dimensional code image may also exist, and an abnormal signal is output to record the two-dimensional code image, so that the two-dimensional code image can be further identified and judged subsequently.
Referring to fig. 3, when the abnormal signal is output, the method for managing and controlling the welding machine further includes:
step S300: the control pipe fitting uses the pipe fitting axis as the axis of rotation and rotates along the preset fixed direction to acquire the rotation angle information.
The fixed direction is clockwise or anticlockwise, and the fixed direction is set by a worker according to the actual situation, which is not described in detail; the pipe fitting is controlled to rotate along the axis of the pipe fitting so that images on the surface of the pipe fitting can be collected, and the rotation of the pipe fitting can be realized by placing a component for driving the pipe fitting to rotate in the temporary placement area, which is a conventional technical means of a person skilled in the art and is not described in detail; meanwhile, the condition of the angle of the pipe fitting is obtained in the rotating process of the pipe fitting, the rotating condition of the pipe fitting is monitored, the information of the rotating angle of the pipe fitting, namely the rotating angle information, is recorded, and the angle can be obtained through an angle sensor.
Step S301: and judging whether the angle value corresponding to the rotation angle information is smaller than a preset rotation threshold value.
The rotation threshold is the minimum value of the rotation angle of the pipe fitting, which ensures that images on the surface of the pipe fitting can be acquired, for example, when the radian of the pipe fitting detected in image detection is 60 degrees, the rotation threshold is 360 degrees to 60 degrees =300 degrees, and a worker adjusts the rotation threshold according to actual image shooting equipment without repeated description; the purpose of judging is to know whether all surfaces of the pipe fitting are subjected to image detection, so that the condition of the pipe fitting can be further judged conveniently.
Step S3011: and if the angle value corresponding to the rotation angle information is smaller than the rotation threshold, judging whether a normal signal exists or not.
When the angle value corresponding to the rotation angle information is smaller than the rotation threshold value, the surface image of the pipe fitting is not completely collected, and the purpose of judging under the second condition is to know whether the two-dimensional code image is collected or not so as to judge whether the two-dimensional code exists on the pipe fitting or not.
Step S30111: if no normal signal exists, the pipe fitting is continuously controlled to rotate.
When no normal signal exists, the two-dimension code image is not collected at the moment, and the control pipe fitting continues to rotate at the moment so as to continue to collect and analyze the two-dimension code condition.
Step S30112: if the normal signal exists, the pipe fitting is controlled to stop rotating so that the scanning assembly can scan the two-dimensional code.
When there is normal signal, explain this moment and have gathered the two-dimensional code image, only need control scanning subassembly this moment scan the two-dimensional code can to make the follow-up normal processing that can of this pipe fitting.
Step S3012: and if the angle value corresponding to the rotation angle information is not less than the rotation threshold value, controlling the pipe fitting to stop rotating and outputting a two-dimensional code missing signal.
When the angle value corresponding to the rotation angle information is not smaller than the rotation threshold value, the surface image of the pipe fitting is collected, but the two-dimensional code image is still not collected, namely the pipe fitting is not printed with the two-dimensional code, the pipe fitting is controlled to stop rotating so as to facilitate the processing of the next step, and meanwhile, a two-dimensional code missing signal is output to identify the situation so as to facilitate the subsequent processing of the situation.
Referring to fig. 4, a method for moving the scanning assembly to the position of the two-dimensional code is also included, and the method comprises the following steps:
step S400: and acquiring the two-dimensional code position information, the arc moving speed information of the scanning assembly and the rotation speed information of the pipe fitting.
The position corresponding to the position information of the two-dimension code is the position of the central point of the two-dimension code, and a coordinate system can be established on the pipe fitting to obtain the position information of the two-dimension code; the speed value corresponding to the arc-shaped moving speed information is the rotating speed of the scanning assembly when the axis of the pipe fitting is used as the rotating shaft, the speed value corresponding to the rotating speed information is the speed value when the pipe fitting rotates, and the two speed values are set by workers according to actual conditions and are not repeated.
Step S401: and determining axial distance information, circumferential radian information and relative direction according to the two-dimensional code position information and a scanning position corresponding to the initial position preset on the pipe fitting.
The scanning position is the position that the two-dimensional code was located when the pipe fitting normally printed the two-dimensional code, can confirm out both along pipe fitting circumference distance and axial distance according to two-dimensional code positional information and scanning position, the distance value that axial distance information corresponds is the distance between scanning position and two-dimensional code current position in the pipe fitting axial, the radian value that circumference radian information corresponds is the distance between scanning position and two-dimensional code current position in pipe fitting circumference, relative direction is scanning position to two-dimensional code current position in the ascending direction of axial.
Step S402: and judging whether the distance value corresponding to the axial distance information is zero or not.
The purpose of judging is whether be in the same circumference lateral wall of pipe fitting in order to learn two-dimensional code position and scanning position to whether learn the scanning subassembly and need follow pipe fitting axial displacement.
Step S4021: and if the distance value corresponding to the axial distance information is not zero, outputting a dislocation signal.
When the distance value corresponding to the axial distance information is not zero, the two-dimensional code position and the scanning position are not located on the same circumferential side wall of the pipe fitting at the moment, namely, the scanning assembly is required to move along the axial direction of the pipe fitting, and a dislocation signal is output to identify the condition so as to facilitate the movement of the subsequent control scanning assembly.
Step S4022: and if the distance value corresponding to the axial distance information is zero, determining arc time information according to the circumferential radian information, the arc moving speed information and the rotating speed information.
When the distance value corresponding to the axial distance information is zero, the scanning assembly does not need to move axially along the pipe fitting at the momentThe mobile device can also move to the two-dimension code position to scan the two-dimension code, the time length corresponding to the arc-shaped time information is the time length of the scanning component and the rotation of the pipe fitting, and the calculation formula is
Wherein
Is the time length corresponding to the arc-shaped time information,
is the radian value corresponding to the circumferential radian information,
is the speed value corresponding to the arc-shaped moving speed information,
the speed value is corresponding to the rotation speed information.
Step S403: the control pipe fitting rotates along fixed direction, and the scanning subassembly moves the time that the arc time information corresponds along fixed direction opposite direction so that the scanning subassembly moves to two-dimensional code department.
The scanning assembly is controlled to move along the opposite direction of the fixed direction, so that the scanning assembly and the pipe fitting can move relatively, the time for the scanning assembly to move to the two-dimensional code is shortened, and the efficiency during scanning operation is improved.
Referring to fig. 5, when the misalignment signal is output, the welder management and control method further includes:
step S500: and acquiring linear moving speed information of the scanning assembly.
When a dislocation signal is output, the two-dimensional code position and the scanning position at the moment are not positioned on the same circumferential side wall of the pipe fitting, and the scanning assembly needs to move along the axial direction of the pipe fitting to move to the two-dimensional code; the speed value corresponding to the linear movement speed information is the speed value of the scanning assembly moving along the axial direction of the pipe fitting, and is set by the staff according to the actual situation, which is not described in detail.
Step S501: and determining linear time information according to the axial distance information and the linear moving speed information.
The time length corresponding to the linear time information is the time that the scanning assembly needs to move along the axial direction of the pipe fitting, and the distance corresponding to the axial distance information is divided by the speed value corresponding to the linear moving speed information to obtain the time length.
Step S502: and judging whether the time length corresponding to the straight line time information is greater than a preset time threshold value.
The time threshold is the time required for the two-dimensional code to rotate to the position of the side wall coaxial with the scanning position at the detected position, and the purpose of judgment is to know whether the two-dimensional code can move to the relative position for the scanning assembly to perform scanning operation when the scanning assembly moves to the circumferential direction where the two-dimensional code is located.
Step S5021: if the time length corresponding to the linear time information is greater than the time threshold, the scanning assembly is controlled to move the time length corresponding to the linear time information along the opposite direction, and the pipe fitting is controlled to rotate along the fixed direction for the time threshold time length.
When the time length corresponding to the linear time information is greater than the time threshold, the fact that the pipe fitting can move to the corresponding position in the process that the scanning assembly moves along the axis is shown, the scanning assembly is controlled to move the time length corresponding to the linear time information along the opposite direction at the moment, the pipe fitting is controlled to rotate the time threshold time length along the fixed direction, the scanning assembly can move to the two-dimensional code rapidly, and normal scanning of the two-dimensional code is achieved.
Step S5022: and if the duration corresponding to the linear time information is not greater than the time threshold, determining first radian information of the rotation of the pipe fitting according to the linear time information.
When the time length corresponding to the linear time information is not greater than the time threshold, it is indicated that the pipe fitting does not move to the position of the side wall coaxial with the scanning position after the scanning assembly moves along the axis, and at the moment, the scanning assembly can be controlled to rotate so as to further reduce the time for the scanning assembly to move to the two-dimensional code; the radian value that first radian information corresponds is the pipe fitting and rotates the radian under the length of time that straight line time information corresponds to in the follow-up further control to pipe fitting and scanning subassembly.
Step S503: and determining second radian information according to the circumferential radian information and the first radian information, and determining secondary time information according to the second radian information, the arc-shaped moving speed information and the rotating speed information.
The radian value corresponding to the second radian information is a difference radian between the current position of the two-dimensional code and the position to which the two-dimensional code needs to move, the radian value corresponding to the circumferential radian information is a 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 assembly and the pipe fitting need to move, and the calculation formula is that
Wherein
Is the time length corresponding to the secondary time information,
and the radian value corresponding to the second radian information.
Step S504: and calculating the sum of the linear time information and the secondary time information to determine total time information, controlling the pipe fitting to rotate along the fixed direction for the duration corresponding to the total time information, and controlling the scanning assembly to move along the opposite direction for the duration corresponding to the linear time information and then controlling the scanning assembly to move along the opposite direction for the duration corresponding to the secondary time information.
The duration corresponding to the sum time information is the sum of the duration corresponding to the linear time information and the duration corresponding to the secondary time information, and is obtained by conventional addition operation, which is not described in detail; the pipe fitting and the scanning assembly are controlled respectively according to the time length corresponding to the linear time information and the time length corresponding to the secondary time information, so that the scanning assembly can move to the two-dimension code position rapidly, the time for the scanning assembly to move to the two-dimension code position is reduced, and the operation efficiency is improved.

step S600: and controlling the blanking assembly to grab the pipe fittings in the temporary placement area to move to a preset waste material area, and counting the two-dimensional code missing signals to determine missing quantity information.
When a two-dimension code missing signal is output, the fact that a two-dimension code is not printed on the pipe fitting is indicated, the pipe fitting cannot be processed at the moment, the blanking assembly is controlled to grab the pipe fitting into a waste material area to achieve collection of the pipe fitting, and workers can conveniently process the pipe fitting, wherein the waste material area is a position set by the workers according to actual conditions; the quantity value corresponding to the missing quantity information is the total quantity value of the two-dimensional code missing signal, that is, the total quantity value of the pipe fitting which is not printed with the two-dimensional code, and the missing quantity information is obtained by counting, which is a conventional technical means of a person skilled in the art and is not described in detail.
Step S601: and counting according to the in-place signals to determine in-place quantity information, and calculating according to the in-place quantity information and the missing quantity information to determine the missing rate of the product.
The quantity value corresponding to the in-place quantity information is the total quantity value of the in-place signal, namely the total quantity value of the pipe scanning, and the in-place quantity information is obtained by counting, which is a conventional technical means of a person skilled in the art and is not described in detail; the product loss rate is the probability of two-dimension code loss of the batch of products, and the calculation formula is
In which
The loss rate of the product is shown as the percentage of product loss,
the quantity value corresponding to the missing quantity information,
the number value corresponding to the in-place number information.
Step S602: and judging whether the product loss rate is greater than a preset incomplete threshold value or not.
The incomplete threshold is the maximum product missing rate allowed by each batch of products, and the purpose of the judgment is to know whether the product missing rate of the batch of products is too high, so as to judge whether the batch of products is qualified.
Step S6021: if the product missing rate is not greater than the preset incomplete threshold, outputting a batch qualified signal.
And when the product deficiency rate is not greater than the preset incomplete threshold, indicating that the product qualified rate of the batch of products meets the requirement, and outputting a batch qualified signal to enable a worker to know the condition.
Step S6022: and if the product missing rate is greater than the preset incomplete threshold value, outputting a batch abnormal signal.
When the product missing rate is greater than the preset incomplete threshold, the condition that the product qualified rate of the batch of products possibly meets the requirement is indicated, and a batch abnormal signal is output to further detect the products.
Step S603: and judging whether the quantity value corresponding to the in-place quantity information is larger than a preset reference threshold value or not when the batch abnormal signal is output.
When a batch abnormal signal is output, the product loss rate is high due to the fact that the number of the scanned pipes is not large, namely 2 pipes are scanned at the beginning, 1 pipe is not printed with a two-dimensional code, the product loss rate is up to 50%, in order to reduce the occurrence of the situation, a reference threshold value is introduced, the reference threshold value is the set minimum scanning quantity value of the pipes, the purpose of judgment is to know whether the number of the currently scanned pipes exceeds the reference threshold value, and therefore the occurrence of inaccurate batch quality detection due to the fact that the number of the detected pipes is too small is reduced.
Step S6031: and if the quantity value corresponding to the in-place quantity information is not greater than the reference threshold, outputting a batch undetermined signal.
When the quantity value corresponding to the in-place quantity information is not larger than the reference threshold value, the measured product deficiency rate cannot represent the overall quality of the batch of products, and a batch undetermined signal is output to record the situation, so that the staff can know the situation, and the attention situation of the staff to the batch of products is emphasized.
Step S6032: and if the quantity value corresponding to the in-place quantity information is larger than the reference threshold value, outputting a batch unqualified signal.
When the quantity value corresponding to the in-place quantity information is larger than the reference threshold value, the measured product loss rate can represent the overall quality of the batch of products, and a batch unqualified signal is output to enable a worker to know the situation, so that the worker can process the situation in time.
