Referring to fig. 2, a flowchart of a mask edge sealing method provided in an embodiment of the present application is shown, where the mask edge sealing method can be applied to a vision control device. As shown in fig. 2, the edge sealing method of the mask may include the following steps:
The gauze mask image is the gauze mask image in the production process, can shoot the gauze mask image in the production process through the industry camera that sets up on the gauze mask production line, can adopt a plurality of industry cameras to shoot, and a plurality of industry cameras can be fixed in the different positions in the gauze mask production line. Wherein, the industrial camera can shoot the gauze mask image according to fixed time interval, and different industrial cameras shoot simultaneously the gauze mask in the production process, perhaps, the industrial camera also can detect the gauze mask and take a picture again when appearing, does not put the restriction in this embodiment.
After obtaining the mask image, in order to obtain actual edge sealing data of the mask, an image processing operation needs to be performed on the mask image. Wherein, the actual banding data of gauze mask is in the actual production process, through the banding data in the gauze mask image that the industry camera was shot, this actual banding data can be for actual folding position data, actual die cutting position data etc..
After the image processing operation is carried out on the mask image, the pixel position coordinate of an actual edge sealing area can be located, the pixel position coordinate is converted into a physical position coordinate through the conversion relation between a pixel coordinate system and a physical coordinate system, and therefore actual edge sealing data of the mask is obtained.
And step 203, comparing the actual edge sealing data with the standard edge sealing data in the preset standard mask template to obtain an error value between the actual edge sealing data and the standard edge sealing data.
Wherein the standard edge sealing data is edge sealing data in a preset standard mask template, a plurality of standard sample masks can be selected, generating edge banding data in a standard mask template according to the average value of the edge banding data in a plurality of standard sample masks, in actual production, the cloth is usually adjusted left and right, so as to adjust the position of the edge banding, therefore, the actual edge banding data of the mask can contain the physical coordinates of the actual edge banding area, then calculating the distance between the actual physical coordinates of the mask and the standard physical coordinates in the preset standard mask template to obtain the error value between the actual edge sealing data and the standard edge sealing data, for example, the actual sealing data of the mask is (0, 0.5), and the standard sealing data in the preset standard mask template is (0, 0.2), so that the error value between the obtained actual sealing data and the standard sealing data is 0.3 mm.
And 204, adjusting the edge sealing position of the mask in the production process according to the error value.
Wherein, the banding position of gauze mask can include the folding position and the die cutting position of gauze mask in the production process, and actual banding data can include actual folding position data and actual die cutting position data, exists the error when actual banding data and standard banding data between, just so can adjust the banding position of gauze mask in the production process through this error value. Optionally, the edge sealing position of the mask in the production process can be directly adjusted through the error value, an error threshold value can also be set, after the error value is compared with the set error threshold value, if the error value exceeds the set error threshold value, the edge sealing position of the mask can be directly adjusted according to the error value, and the edge sealing position of the mask can also be adjusted according to the difference value between the error value and the set error threshold value. The sealing edge position adjusting method comprises a left adjusting mode and a right adjusting mode, an error value can be set to be positive, the sealing edge position can be adjusted to the left, and the sealing edge position can also be adjusted to the left when the error value is negative.

For example, when the error between the actual folding position data and the standard folding position data is +0.5mm, the cloth can be moved to the left by 0.5mm, and when the error between the actual die cutting position data and the standard die cutting position data is 0, the die cutting position does not need to be adjusted. Optionally, when the error between the actual folding position data and the standard folding position data is +0.5mm, if the preset error threshold is ± 0.2mm, that is, plus or minus 0.2mm, after comparing the error between the actual folding position data and the standard folding position data, which is +0.5mm, with the preset error threshold, which is ± 0.2mm, the error +0.5mm exceeds the preset error threshold +0.2mm, at this time, the fabric is moved leftward by 0.5mm, or is +0.3mm after being different from the preset error threshold, and the fabric is moved leftward by 0.3mm according to the difference.

Referring to fig. 3, a flowchart of a method for acquiring a mask image according to an embodiment of the present application is shown, where the method for acquiring a mask image may be applied to a vision control apparatus. As shown in fig. 3, the method for acquiring the mask image may include the steps of:
Wherein, the positive industry camera can be fixed set up behind the folding station on gauze mask production line equipment, be used for shooing first gauze mask image, this first gauze mask image includes the positive folding position of gauze mask, wherein, the positive industry camera can shoot first gauze mask image according to fixed time interval, perhaps, positive industry camera also can be the retakes when detecting that there is the gauze mask to appear, for example, install infrared detector on the positive industry camera, when the gauze mask passes through, infrared detector detects the gauze mask, give positive industry camera output trigger signal, positive industry camera begins to shoot, the restriction does not put forward in this embodiment. In order to shoot the first mask image more clearly, a front visual light source can be added near the lens of the front industrial camera, so that illumination is provided for the front industrial camera to shoot the first mask image, the first mask image which is clear in black and white can be shot, namely, the color in the first mask can be better restored, and the shot first mask image is more real.
Wherein, the back industrial camera also can fix the folding station that sets up on gauze mask production line equipment after, be used for shooing second gauze mask image, this second gauze mask image includes the back folding position of gauze mask, wherein, the back industrial camera can shoot second gauze mask image according to fixed time interval, perhaps, the back industrial camera also can detect to have the gauze mask to appear and take a picture again, for example, install infrared detector on the back industrial camera, when the gauze mask passes through, infrared detector detects the gauze mask, give back industrial camera output trigger signal, the back industrial camera begins to take a picture, do not put the restriction in this embodiment. It should be noted that the back industrial camera and the front industrial camera described above should take pictures of the back folded position and the front folded position, respectively, in the same manner. Optionally, based on the same initial time, in the case that the front industrial camera takes the first mask image at fixed time intervals, the back industrial camera should also take the second mask image at the same time intervals, so as to ensure that the first mask image and the second mask image are taken simultaneously, for example, the initial time is T, the time interval is T, and if the time when the front industrial camera takes the first mask image is T + T, the time when the back industrial camera takes the second mask image should also be T + T. For the second gauze mask image of more clear shooting, can also increase back vision light source near back industry camera lens to shoot second gauze mask image for back industry camera provides the illumination, thereby can shoot out the second gauze mask image that black and white is clear, also can come out with the better reduction of the colour in the second gauze mask, make the second gauze mask image of shooing more true.
The third mask image may include an actual die cutting position of the mask, wherein the third mask image may be captured by the vertical industrial camera at a fixed time interval, or the vertical industrial camera may capture the third mask image when detecting the presence of the mask, for example, an infrared detector is installed on the vertical industrial camera, and when the mask passes through, the infrared detector detects the mask, and outputs a trigger signal to the vertical industrial camera, and the vertical industrial camera starts to capture the image, or the vertical industrial camera may be triggered to start to capture the image by sensing a signal change of the photoelectric sensor, which is not limited in the embodiment. In order to shoot the third mask image more clearly, a longitudinal visual light source can be added near the lens of the longitudinal industrial camera, so that illumination is provided for the third mask image shot by the longitudinal industrial camera, the third mask image with clear black and white can be shot, the color of the third mask can be better restored, and the shot third mask image is more real.
Through setting up the positive industry camera on gauze mask production line equipment, acquire first gauze mask image, through setting up the back industry camera on gauze mask production line equipment, acquire second gauze mask image, through setting up the vertical industry camera on gauze mask production line equipment, acquire third gauze mask image, three gauze mask images that obtain like this have just included the folding position and the cross cutting position of gauze mask, just so can judge folding position and cross cutting position respectively, thereby can synthesize the judged result of folding position and cross cutting position and judge gauze mask banding effect, make the judgement to gauze mask banding effect more comprehensive, thereby it is more high-efficient and accurate when making adjustment gauze mask banding position.
In one embodiment, the third mask image is acquired by a longitudinal industrial camera arranged on the mask production line equipment, and the third mask image acquisition method comprises the following steps: when the jumping of the signals of the photoelectric sensors on the mask production line equipment, which are adjacent twice, is detected, the photographing function of the longitudinal industrial camera is triggered to photograph and acquire a third mask image.
The photoelectric sensor can be arranged near a longitudinal industrial camera on mask production line equipment, when a mask passes through, the adjacent two signals of the photoelectric sensor can jump, for example, when no mask passes through, the current signal of the photoelectric sensor is 0, when the mask passes through at the next moment, the signal of the photoelectric sensor jumps from 0 to 1, at the moment, the photographing function of the longitudinal industrial camera is triggered to photograph to acquire a third mask image, and when the adjacent two signals of the photoelectric sensor on the mask production line equipment are detected to jump, the photographing function of the longitudinal industrial camera is triggered, so that the storage space of the longitudinal industrial camera can be saved, and the calculation cost of a control system is also saved.
After the mask image in the production process is obtained, the specific process of obtaining the actual edge sealing data of the mask is introduced by carrying out image processing operation on the mask image as follows:
and matching the mask image with the standard mask template to obtain actual edge sealing data. The mask image may be matched with a standard mask template according to mask identification features, indentation features, ultrasonic hole features, and the like, the seal edge position in the mask image may be searched by using a single line extraction method in machine vision, or the seal edge position in the mask image may be searched by using a template matching method in image processing, which is not limited in this embodiment. Searching the edge sealing position in the mask image comprises searching a folding position and a die cutting position in the mask image, wherein the obtained folding position and the die cutting position are pixel positions in the mask image, and finally converting the pixel position coordinates into physical position coordinates through a conversion relation between a pixel coordinate system and a physical coordinate system, so that the actual edge sealing data of the mask are obtained. For example, when the single line extraction method in machine vision is used for searching the edge sealing position in the mask image, because the mask image has a specific template format, if the edge sealing position in the mask image is judged by using the ultrasonic hole characteristic line, the ultrasonic hole characteristic line position can be quickly extracted by using the single line extraction method, so that the actual edge sealing data can be quickly and efficiently obtained.
At the in-process of actual production gauze mask, judge the banding effect of gauze mask and include: judge folding position effect and the cross cutting position effect two parts of gauze mask, consequently, the actual banding data that obtain have also included the actual folding position data of gauze mask and the actual cross cutting position data of gauze mask, if the folding position effect and the cross cutting position effect of gauze mask are not good, then just need respectively to adjust the folding position effect and the cross cutting position of gauze mask.
The specific processes of adjusting the folding position and the die cutting position of the mask in the production process are described as follows:
and (I) comparing the actual edge sealing data with standard edge sealing data in a preset standard mask template to obtain an error value between the actual edge sealing data and the standard edge sealing data. Referring to fig. 4, a flowchart of adjusting a folded position of a mask according to an embodiment of the present disclosure is shown, where the method for adjusting a folded position of a mask can be applied to a vision control apparatus. As shown in fig. 4, the method for adjusting the folding position of the mask may include the following steps:
Optionally, the actual folding position data of the mask may be subtracted from the standard folding position data, and the difference is used as a first error value, for example, the ultrasonic hole feature position data may be extracted from the actual folding position data of the mask, and since the folding position is adjusted by adjusting the cloth left and right in actual production, the actual folding position data of the mask may include physical coordinates of an actual folding position region, that is, the ultrasonic hole feature position data extracted from the actual folding position data of the mask is used as the physical coordinates thereof, and then a distance is calculated between the actual physical coordinates of the ultrasonic hole feature and the standard position coordinates of the ultrasonic hole feature in the standard folding position data, and the distance is used as the first error value.
The preset first error threshold is a difference value between actual folding position data and standard folding position data of the preset mask, and when the first error value is larger than the preset first error threshold, a folding deviation correction amount is sent to the adjusting motor, the folding deviation correction amount can be the first error value, and can also be the difference value between the first error value and the preset first error threshold, wherein the folding deviation correction amount is used for controlling the adjusting motor to drive the cloth to move so as to adjust the folding position of the mask in the production process, and therefore the triangular plate device in the folding station is always kept in the middle of the cloth. In actual production, the preset first error threshold is generally set to ± 0.2mm, i.e. plus or minus 0.2mm, for example, when the first error value is +0.5mm, the folding deviation correction amount can be +0.3mm, and at this time, the adjustment motor can be controlled to drive the cloth to move 0.3mm to the left.
Carry out the comparison through the actual folding position data with the gauze mask with the folding position data of standard, obtain first error value, if first error value is greater than first error threshold value of predetermineeing, then send folding deviation amount of rectifying to adjustment motor, the folding deviation amount of rectifying that obtains is used for controlling adjustment motor and drives the cloth and move, with the folding position of gauze mask in the adjustment production process, can carry out automatic adjustment to the folding position of gauze mask in the production process like this, thereby make the folding position of gauze mask remain at reasonable within range all the time, thereby guarantee that the banding of gauze mask is effectual, thereby improve the productivity ratio of gauze mask.
In one embodiment, adjusting the position of the edge sealing of the mask during the production process according to the error value comprises: if the error value exceeds a preset first error threshold value, acquiring a folding deviation correction amount according to the front folding position of the mask and the back folding position of the mask, and sending the folding deviation correction amount to an adjusting motor; the folding deviation correction amount is used for controlling the adjusting motor to drive the cloth to move so as to adjust the folding position of the mask in the production process.
Wherein, after the mask is folded, the mask comprises a front folding position and a back folding position, and both the front folding position and the back folding position can comprise a mask identification characteristic position, for example, the mask identification characteristic is KN95 mask identification characteristic, when the folding position of the mask is adjusted in the production process, if an error value exceeds a preset first error threshold value, a folding correction amount is obtained according to the front folding position of the mask and the back folding position of the mask, and the folding correction amount is sent to an adjusting motor, optionally, the front folding position data of the mask is compared with the front folding position data in a preset standard mask template to obtain a first folding correction amount, the back folding position data of the mask is compared with the back folding position data in the preset standard mask template to obtain a second folding correction amount, and the first folding correction amount and the second folding correction amount are superposed and operated, and obtaining the folding deviation correction amount, similarly comparing the folding deviation correction amount with a preset first error threshold value of +/-0.2 mm, and if the folding deviation correction amount exceeds the first error threshold value, adjusting the folding position according to the folding deviation correction amount.
Optionally, in practical application, the value obtained by superimposing the first folding deviation-correcting amount and the second folding deviation-correcting amount may be averaged, and the average value may be used as the folding deviation-correcting amount. For example, if the first folding deviation-correcting amount is +0.3mm and the second folding deviation-correcting amount is-0.3 mm, the folding deviation-correcting amount is 0 after the first folding deviation-correcting amount and the second folding deviation-correcting amount are subjected to the superposition operation, and then the folding position does not need to be adjusted; if the first folding deviation correction amount is +0.3mm and the second folding deviation correction amount is-1.3 mm, averaging the value obtained after the superposition operation of the first folding deviation correction amount and the second folding deviation correction amount to obtain the folding deviation correction amount of-0.5 mm, wherein the folding deviation correction amount exceeds a preset first error threshold value, and at the moment, the adjusting motor can be controlled to drive the cloth to move 0.5mm rightward.
If the error value exceeds a preset first error threshold value, the folding deviation correction amount is obtained according to the front folding position of the mask and the back folding position of the mask, the folding deviation correction amount is sent to the adjusting motor and used for controlling the adjusting motor to drive the cloth to move, the folding position of the mask in the production process is adjusted, the folding position data of the mask and the back folding position data of the mask are subjected to superposition operation to obtain the final folding deviation correction amount, the accuracy of calculating the folding deviation correction amount can be improved, and the adjusted folding position is more accurate.
And (II) comparing the actual edge sealing data with standard edge sealing data in a preset standard mask template to obtain an error value between the actual edge sealing data and the standard edge sealing data.
