Description

Technical Field

[0001] The invention belongs to the technical field of intelligent detection of nozzles, and in particular to an intelligent detection system and method for a nozzle of a perfume bottle. Background Art

[0002] The image of the nozzle spray is captured by a high-resolution industrial camera, and the image is analyzed using an image processing algorithm to detect key parameters such as the nozzle's spray shape, spray angle, and spray volume, so as to determine whether the nozzle's performance meets the standards. However, there is still a phenomenon that the nozzle atomization uniformity is poor when the nozzle spray range is large.

[0003] In the prior art, only key parameters such as the spray shape, spray angle, and spray volume of the nozzle are detected individually, but the spray performance of the nozzle is not considered comprehensively. The present technical solution not only detects the spray range of the nozzle, but also detects the atomization uniformity of the nozzle, comprehensively evaluates the performance of the perfume nozzle in spraying perfume by detecting the spray range and atomization uniformity of the perfume nozzle multiple times, and determines whether the cause of generating the nozzle performance unstable signal is caused by abnormal detection operation by detecting the deviation between the pressing time and the preset pressing time, and the deviation between the pressing depth and the preset pressing depth. If the cause of generating the nozzle unstable signal is not caused by abnormal detection operation, it means that the perfume nozzle equipment is unqualified.

[0004] To this end, the present invention provides an intelligent detection system and method for a perfume bottle nozzle. Summary of the invention

[0010] Step three: When a nozzle performance unstable signal is generated, the pending nozzle detection data obtained from multiple detections are processed, wherein the pending nozzle detection data includes a pressing time deviation degree value and a pressing depth deviation degree value. The pressing time deviation degree value and the pressing depth deviation degree value are processed to obtain a pending evaluation value, and compared with the threshold. If the pending evaluation value is greater than the pending evaluation threshold, it means that the nozzle performance unstable signal is caused by abnormal detection operation.

[0065] Figure 3 It is a system flow chart of embodiment 3 of the present invention. DETAILED DESCRIPTION

[0066] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0067] Example 1

[0068] like Figure 1 As shown, an intelligent detection method for a perfume bottle nozzle according to an embodiment of the present invention includes:

[0069] Step 1: Perform multiple tests on the perfume bottle nozzle to obtain perfume nozzle test data, wherein the perfume nozzle test data includes a spray range value and an atomization uniformity value;

[0070] In some embodiments, the perfume nozzle is fixed on the spray test device, and the perfume nozzle is tested multiple times to obtain the test data of the perfume nozzle, wherein the test data of the perfume nozzle includes a spray range value and an atomization uniformity value, and the specific acquisition process is as follows:

[0071] When testing the perfume nozzle, a high-speed camera is set to obtain multiple groups of images of the perfume nozzle spraying through the high-speed camera, and each group of images of the perfume nozzle spraying obtained by the high-speed camera is marked as a nozzle spraying image;

[0072] Based on the nozzle spray images, the plurality of nozzle spray images are sequentially identified by an image sensor, and spray profile data of each nozzle spray image is extracted, wherein the spray profile data includes a target area and a cone area;

[0073] It should be noted that: since the outline of the nozzle spray image is similar to a cone, the target area represents: the outline of the circular area corresponding to the bottom of the cone; the conical area represents: the outline of the conical area corresponding to the cone surface;

[0074] Exemplarily, the process of obtaining the injection range value is as follows:

[0075] Obtaining the target area ratio and the cone area ratio, adding the target area ratio and the cone area ratio to obtain a spray range value;

[0076] First, the target area ratio is obtained as follows:

[0077] Obtain the target area, add and average the target area values ​​of multiple groups of target areas, and obtain the target area value;

[0078] Calculate the ratio of the target area value to the standard target area value to obtain the target area ratio;

[0079] It can be understood that the target area ratio means the average area of ​​the circular area contour at the bottom of the cone (i.e., the target area) in the multiple sets of perfume nozzle spraying images acquired by the high-speed camera. This area value reflects the average size of the circular area formed at the bottom of the cone when the perfume nozzle sprays. If the target area is relatively large, it means that when the perfume nozzle sprays, the circular area formed at the bottom of the cone is relatively large and the spraying range is relatively large. If the target area is relatively small, it means that when the perfume nozzle sprays, the circular area formed at the bottom of the cone is relatively small and the spraying range is relatively small.

[0080] The second specific method for obtaining the cone area ratio is:

[0081] Obtain the area of ​​the cone region, add and average the areas of multiple groups of cone regions, and obtain the area value of the cone region;

[0082] The area value of the cone area is calculated by comparing it with the area value of the standard cone area to obtain the cone area ratio;

[0083] It can be understood that: the meaning of the cone area ratio is: the average area of ​​the cone area contour (i.e., cone area) of the cone surface in the multiple groups of perfume nozzle spraying images obtained by the high-speed camera. This area value reflects the average size of the cone area formed by the cone surface when the perfume nozzle sprays. If the cone area is relatively large, it means that when the perfume nozzle sprays, the cone area formed by the cone surface is large and the spray range is large. If the cone area is relatively small, it means that when the perfume nozzle sprays, the cone area formed by the cone surface is small and the spray range is small.

[0084] The process of obtaining the atomization uniformity value is as follows:

[0085] Obtaining a target area average value and a sector area average value, adding the target area average value and the sector area average value to obtain an atomization average value;

[0086] First, the method for obtaining the average value of the target area is as follows:

[0087] Mark the center of the circular area corresponding to the bottom of the cone as the center of the target area;

[0088] Get the center of the target area, divide the target area into several concentric circle areas with the center as the circle point, and get the area value of each concentric circle area, and the area value of each concentric circle area is equal;

[0089] Obtain the perfume area value in each concentric circle area, calculate the ratio of the perfume area value in each concentric circle area to the area value of the divided concentric circle area, and obtain the perfume area ratio in the concentric circle area;

[0090] The perfume area ratios in several concentric circles are integrated into a set P, where the set P is

[0091] P = {p1, p2, p3, ...,;

[0092] It can be understood that: the arrangement order of p1, p2, p3 in the set P is arranged from the inside to the outside according to the positions of the concentric circle areas divided by the target area;

[0093] For example, what is represented is the perfume area ratio of the innermost concentric circle area of ​​the target area, and what is represented is the perfume area ratio of the outermost concentric circle area of ​​the target area;

[0094] By formula: The average value of the concentric circle areas is calculated, where n represents the total number of concentric circle areas divided by the target area and is an even number;

[0095] Add and average the average values ​​of all concentric circle areas to obtain the average value of the target area;

[0096] It can be understood that the target area uniformity value means: the uniformity of the distribution of perfume in the entire target area after multiple tests of the perfume nozzle spraying. If the target area uniformity value is large, it means that in the target area, the deviation between the perfume area ratio in the inner concentric circle area and the perfume area ratio in the outer concentric circle area is large. Therefore, the perfume distribution in the entire target area is relatively uneven, and the atomization uniformity of the perfume nozzle is low. On the contrary, if the target area uniformity value is small, it means that in the target area, the deviation between the perfume area ratio in the inner concentric circle area and the perfume area ratio in the outer concentric circle area is small. Therefore, the perfume distribution in the entire target area is relatively uniform, and the atomization uniformity of the perfume nozzle is high.

[0097] The second specific method for obtaining the average value of the cone area is:

[0098] Obtain the cone vertex of the cone area, divide the cone area into several concentric sector areas with the vertex as the center, and obtain the area value of each concentric sector area, and the area value of each concentric sector area is equal;

[0099] Calculate the ratio of the perfume area value in each concentric sector area to the area value of the divided concentric sector area to obtain the perfume area ratio in the concentric sector area;

[0100] The perfume area ratios in several concentric fan-shaped regions are integrated into a set Q, where the set Q is

[0101] Q = {q1, q2, q3, ...,;

[0102] It can be understood that: the arrangement order of q1, q2, q3,. in the set Q is arranged in a clockwise order according to the concentric fan-shaped areas in the cone area;

[0103] By formula: The average value of the concentric sector regions is calculated, where m represents the total number of concentric sector regions divided by the cone region, and is an even number;

[0104] The average values ​​of all concentric fan-shaped areas are added and averaged to obtain the average value of the cone area;

[0105] It can be understood that the meaning of the cone area uniformity value is: the uniformity of the distribution of the perfume after multiple tests of the perfume nozzle spraying in the entire cone area. If the cone area uniformity value is large, it means that the perfume deviation in the adjacent concentric fan areas in the cone area is large. Therefore, the perfume distribution in the entire cone area is relatively uneven, and the perfume nozzle atomization uniformity is low. On the contrary, if the cone area uniformity value is small, it means that the perfume deviation in the adjacent concentric fan areas in the cone area is small. Therefore, the perfume distribution in the entire cone area is relatively uniform, and the perfume nozzle atomization uniformity is high.

[0106] Step 2: Based on the spray range value and the atomization uniformity value, the nozzle detection value is obtained and compared with the threshold value to generate a signal indicating whether the nozzle performance is stable;

[0107] Wherein, the signal of whether the nozzle performance is stable includes a nozzle performance stable signal or a nozzle performance unstable signal;

[0108] In some embodiments, when the spray range value and the atomization uniformity value are obtained, the spray range value and the atomization uniformity value are ratio-calculated to obtain the nozzle detection value, and the nozzle detection value is compared with the nozzle detection threshold value. The comparison process is as follows:

[0109] If the nozzle detection value is greater than or equal to the nozzle detection threshold, it means that the spray range of the detected perfume nozzle is large and the perfume sprayed from the nozzle is highly uniform, and a nozzle performance stability signal is generated, and the perfume nozzle corresponding to the nozzle performance stability signal is marked as a qualified perfume nozzle;

[0110] If the nozzle function value is less than the nozzle function threshold, it means that the spray range of the detected perfume nozzle is small and the perfume sprayed from the nozzle is less uniform, and a nozzle performance unstable signal is generated, and the perfume nozzle corresponding to the nozzle performance unstable signal is marked as a perfume nozzle to be detected;

[0111] The specific implementation scheme of the embodiment of the present invention is: fixing the perfume nozzle on the spray testing device, and performing multiple tests on the perfume nozzle to obtain test data of the perfume nozzle, wherein the test data of the perfume nozzle includes a spray range value and an atomization uniformity value, performing a ratio calculation between the spray range value and the atomization uniformity value to obtain a nozzle detection value, and comparing the nozzle detection value with the nozzle detection threshold. If the nozzle detection value is greater than or equal to the nozzle detection threshold, a nozzle performance stable signal is generated; if the nozzle function value is less than the nozzle function threshold, a nozzle performance unstable signal is generated, thereby comprehensively evaluating the performance of the perfume nozzle in spraying perfume by detecting the spray range and atomization uniformity of the perfume nozzle multiple times.

[0112] Example 2

[0113] like Figure 2 As shown, an intelligent detection method for a perfume bottle nozzle according to an embodiment of the present invention includes:

[0114] Step 3: Based on the nozzle performance unstable signal, the detection data of the pending nozzle after multiple tests are processed to obtain the pending evaluation value, and compare it with the threshold value to analyze whether it is caused by abnormal detection operation;

[0115] In some embodiments, when a nozzle performance unstable signal is generated, the pending nozzle detection data after multiple detections are processed, wherein the pending nozzle detection data includes a pressing time deviation degree value and a pressing depth deviation degree value, and the pressing time deviation degree value and the pressing depth deviation degree value are processed to obtain a pending evaluation value;

[0116] First, the method for obtaining the pressing time deviation value is as follows:

[0117] Each time the perfume nozzle is detected, a time node corresponding to the initial position of the perfume nozzle is obtained and marked as the initial time node;

[0118] Get the time node corresponding to the position when the perfume nozzle is pressed to the end, and mark it as the end time node;

[0119] Subtract the end time node from the initial time node to obtain the pressing time value;

[0120] Obtain the pressing time value after each detection of the perfume nozzle, and subtract the pressing time value after each detection of the perfume nozzle from the preset pressing time to obtain the pressing time deviation value;

[0121] Calculate the ratio of the pressing time deviation value to the preset pressing time to obtain the pressing time deviation coefficient;

[0122] The pressing time deviation coefficients after multiple tests of the perfume nozzle are added and averaged to obtain the pressing time deviation degree value;

[0123] It can be understood that the meaning of the pressing time deviation degree value is: reflecting the average degree of deviation between the actual pressing time and the preset pressing time during multiple tests of the perfume nozzle. Specifically, the larger the value, the greater the deviation between the actual pressing time and the preset pressing time when testing the perfume nozzle, and the nozzle performance unstable signal is caused by abnormal testing operation. On the contrary, the smaller the value, the smaller the deviation between the actual pressing time and the preset pressing time when testing the perfume nozzle, and the nozzle performance unstable signal is not caused by abnormal testing operation.

[0124] Second, the method for obtaining the pressing depth deviation value is as follows:

[0125] Each time the perfume nozzle is detected, the pressing depth corresponding to the initial position of the perfume nozzle is obtained and marked as the initial pressing depth;

[0126] Get the pressing depth corresponding to the position at the end of pressing the perfume nozzle, and mark it as the end pressing depth;

[0127] Subtract the final pressing depth from the initial pressing depth to obtain the pressing depth value;

[0128] Obtaining the pressing depth value after each detection of the perfume nozzle, and subtracting the pressing depth value after each detection of the perfume nozzle from the preset pressing depth value to obtain a pressing depth deviation value;

[0129] Calculate the ratio of the pressing depth deviation value to the preset pressing depth value to obtain a pressing depth deviation coefficient;

[0130] The pressing depth deviation coefficients after multiple tests of the perfume nozzle are added and averaged to obtain the pressing depth deviation degree value;

[0131] It can be understood that the meaning of the pressing depth deviation value is: the average degree of deviation between the actual pressing depth of the perfume nozzle and the preset pressing depth value in multiple tests of the perfume nozzle. Specifically, the larger the value, the greater the deviation between the actual pressing depth and the preset pressing depth when testing the perfume nozzle, and the nozzle performance unstable signal is caused by abnormal testing operation. On the contrary, the smaller the value, the smaller the deviation between the actual pressing depth and the preset pressing depth when testing the perfume nozzle, and the nozzle performance unstable signal is not caused by abnormal testing operation.

[0132] The method for obtaining the pending evaluation value is:

[0133] Obtaining a compression time deviation value and a compression depth deviation value, and adding the compression time deviation value and the compression depth deviation value to obtain a pending evaluation value;

[0134] It should be further explained that the meaning of the pending evaluation value is: a comprehensive quantitative evaluation of the accuracy of the perfume nozzle detection evaluation is conducted by combining the two factors of the pressing time deviation degree value and the pressing depth deviation degree value, reflecting the comprehensive influence of the deviation degree between the actual pressing time of the perfume nozzle and the preset pressing time, and the deviation degree between the actual pressing depth and the preset pressing depth in the process of multiple detections of the perfume nozzle. Specifically, the larger this value is, the greater the deviation between the pressing time and the pressing depth from the preset value in the process of multiple detections of the perfume nozzle. Therefore, the nozzle performance unstable signal is caused by abnormal detection operation. On the contrary, in the process of multiple detections of the perfume nozzle, the deviation between the pressing time and the pressing depth from the preset value is small. Therefore, the nozzle performance unstable signal is not caused by abnormal detection operation.

[0135] The pending evaluation value is compared with the pending evaluation threshold. The comparison process is as follows:

[0136] If the pending evaluation value is greater than the pending evaluation threshold, it means that during the multiple tests of the perfume nozzle, both the pressing time and the pressing depth have large deviations from the preset values, and therefore, the nozzle performance instability signal is caused by abnormal testing operation;

[0137] If the pending evaluation value is less than or equal to the pending evaluation threshold, it means that during the multiple tests of the perfume nozzle, the deviations of both the pressing time and the pressing depth from the preset values ​​are small, and therefore, the nozzle performance instability signal is not caused by abnormal detection operation;

[0138] The specific implementation method of the embodiment of the present invention is as follows: when a nozzle performance unstable signal is generated, the pending nozzle detection data after multiple detections is processed, wherein the pending nozzle detection data includes a pressing time value and a pressing depth value, the pressing time value and the pressing depth value are processed to obtain a pending evaluation value, and compared with the pending evaluation threshold, to analyze whether the generation of the nozzle performance unstable signal is caused by abnormal detection operation, thereby determining whether the cause of the generation of the nozzle performance unstable signal is caused by abnormal detection operation by detecting the degree of deviation between the pressing time and the preset pressing time, as well as the degree of deviation between the pressing depth and the preset pressing depth, if the cause of the generation of the nozzle unstable signal is not caused by abnormal detection operation, it means that it is caused by unqualified perfume nozzle equipment.
