Description

Technical Field

[0001] The invention belongs to the technical field of intelligent nozzle detection, and in particular to an intelligent detection system and method for a perfume bottle nozzle. 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 of the nozzle, such as the spray shape, spray angle, and spray volume, are detected individually. However, the nozzle's spray performance is not considered by comprehensively considering key parameters such as the nozzle's spray shape, spray angle, and spray volume. The present technical solution not only detects the nozzle's spray range, but also detects the nozzle's atomization uniformity. By comprehensively considering the nozzle's spray range and atomization uniformity, and detecting the spray range and atomization uniformity of the perfume nozzle multiple times, the perfume nozzle's performance in spraying perfume is comprehensively evaluated. 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, it is determined whether the cause of generating the nozzle performance unstable signal is caused by abnormal detection operation. 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

[0008] 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;

[0009] Wherein, the signal of whether the nozzle performance is stable includes a nozzle performance stable signal or a nozzle performance unstable signal;

[0010] Step three: When the nozzle performance unstable signal is generated, the pending nozzle detection data obtained from multiple detections are processed, wherein the pending nozzle detection data includes the pressing time deviation degree value and the 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. If the pending evaluation value is less than or equal to the pending evaluation threshold, the nozzle performance unstable signal is not caused by abnormal detection operation.

[0033] The perfume area ratios in several concentric fan-shaped regions are integrated into a set Q, where the set Q is ;

[0034] All concentric fan-shaped areas are evenly divided Add and average the values ​​to get the average value of the cone area.

If the pending evaluation value is greater than the pending evaluation threshold, it means that the nozzle performance instability signal is caused by an abnormal detection operation.

[0061] The present invention will be further described below with reference to the accompanying drawings.

[0063] Figure 2 is a flowchart of the steps of Example 2 of the present invention;

[0064] Figure 3 This is a system flow chart of Example 3 of the present invention. DETAILED DESCRIPTION

[0065] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0066] Example 1

[0067] like Figure 1 As shown, an intelligent detection method for a perfume bottle nozzle according to an embodiment of the present invention includes:

[0068] 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;

[0069] In some embodiments, a fragrance nozzle is fixed to a spray testing device and tested multiple times to obtain test data of the fragrance nozzle. The test data of the fragrance nozzle includes a spray range value and an atomization uniformity value. The specific acquisition process is as follows:

[0070] When testing the perfume nozzle, a high-speed camera is set to obtain multiple sets of images of the perfume nozzle spraying through the high-speed camera, and each set of images of the perfume nozzle spraying obtained by the high-speed camera is marked as a nozzle spraying image;

[0071] 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;

[0072] 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;

[0073] Exemplarily, the process of obtaining the injection range value is as follows:

[0074] Obtaining a target area ratio and a cone area ratio, and summing the target area ratio and the cone area ratio to obtain a spray range value;

[0075] First, specifically, the target area ratio is obtained as follows:

[0076] Obtain the target area, add up the areas of multiple groups of target areas and take the average value to obtain the target area value;

[0077] Calculate the ratio of the target area value to the standard target area value to obtain the target area ratio;

[0078] It is understood that the target area ratio represents the average area of ​​the circular area outline at the bottom of the cone (i.e., the target area) in multiple sets of fragrance nozzle spray images captured by a high-speed camera. This area value reflects the average size of the circular area formed by the bottom of the cone when the fragrance nozzle sprays. If the target area is relatively large, it means that the circular area formed by the bottom of the cone is larger when the fragrance nozzle sprays, and the spray range is larger. If the target area is relatively small, it means that the circular area formed by the bottom of the cone is smaller when the fragrance nozzle sprays, and the spray range is smaller.

[0079] The second specific method for obtaining the cone area ratio is:

[0080] Obtain the area of ​​the cone region, add up the areas of multiple groups of cone regions and take the average value to obtain the area value of the cone region;

[0081] 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;

[0082] It is understood that the conical area ratio represents the average area of ​​the conical area outline of the conical surface (i.e., the conical area) in multiple sets of perfume nozzle spray images captured by a high-speed camera. This area value reflects the average size of the conical area formed by the conical surface when the perfume nozzle sprays. If the conical area is relatively large, it means that the conical area formed by the conical surface is large when the perfume nozzle sprays, and the spray range is large. If the conical area is relatively small, it means that the conical area formed by the conical surface is small when the perfume nozzle sprays, and the spray range is small.

[0083] The process of obtaining the atomization uniformity value is as follows:

[0084] Obtaining a target area average value and a sector area average value, and summing the target area average value and the sector area average value to obtain an atomization average value;

[0085] First, specifically, the method for obtaining the average value of the target area is:

[0086] Mark the center of the circular area corresponding to the bottom of the cone as the center of the target area;

[0087] Get the center of the target area, divide the target area into several concentric circle areas with the center as the circle point, and obtain the area value of each concentric circle area, and the area value of each concentric circle area is equal;

[0088] 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;

[0089] The perfume area ratios in several concentric circles are integrated into a set P, where the set P is ;

[0090] It is understandable that: in the set P The arrangement order is based on the position of the concentric circle areas divided by the target area from the inside to the outside;

[0091] For example, It represents the perfume area ratio of the innermost concentric circle area of ​​the target area. What is shown is the perfume area ratio of the outermost concentric circle area of ​​the target area;

[0092] By formula: , calculate the average value of the concentric circle area , where n represents the total number of concentric circle areas divided by the target area, and is an even number;

[0093] All concentric circle areas are uniformly divided Add and average the values ​​to get the average value of the target area;

[0094] It can be understood that the target area uniformity value represents the degree of 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 within the target area, the deviation between the perfume area ratio of the inner concentric circle area and the perfume area ratio of 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. Conversely, if the target area uniformity value is small, it means that within the target area, the deviation between the perfume area ratio of the inner concentric circle area and the perfume area ratio of 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.

[0095] The second specific method for obtaining the average value of the cone area is:

[0096] 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;

[0097] Calculate the ratio of the perfume area value in each concentric sector to the area value of the divided concentric sector to obtain the perfume area ratio in the concentric sector;

[0098] The perfume area ratios in several concentric fan-shaped regions are integrated into a set Q, where the set Q is ;

[0099] It is understandable that: in the set Q The arrangement order is based on the clockwise order of the concentric fan-shaped areas in the cone area;

[0100] By formula: , calculate the average value of the concentric sector areas, where m represents the total number of concentric sector areas divided by the cone area, and is an even number;

[0101] The average value of all concentric fan-shaped areas is added and averaged to obtain the average value of the cone area;

[0102] It can be understood that the conical area uniformity value represents the degree of uniformity of the distribution of perfume in the entire conical area after multiple tests of the perfume nozzle. If the conical area uniformity value is large, it means that the degree of deviation of the perfume in adjacent concentric fan areas within the conical area is large. Therefore, the perfume distribution in the entire conical area is relatively uneven, and the atomization uniformity of the perfume nozzle is low. Conversely, if the conical area uniformity value is small, it means that the degree of deviation of the perfume in adjacent concentric fan areas within the conical area is small. Therefore, the perfume distribution in the entire conical area is relatively uniform, and the atomization uniformity of the perfume nozzle is high.

[0103] 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;

[0104] Wherein, the nozzle performance stability signal includes a nozzle performance stable signal or a nozzle performance unstable signal;

[0105] In some embodiments, when the spray range value and the atomization uniformity value are obtained, a ratio calculation is performed between the spray range value and the atomization uniformity value to obtain a nozzle detection value, and the nozzle detection value is compared with the nozzle detection threshold. The comparison process is as follows:

[0106] 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 relatively uniform. 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.

[0107] 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 not uniform. 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.

[0108] The specific implementation plan 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. In this way, by repeatedly detecting the spray range and atomization uniformity of the perfume nozzle, the performance of the perfume nozzle in spraying perfume is comprehensively evaluated.

[0109] Example 2

[0110] like Figure 2 As shown, an intelligent detection method for a perfume bottle nozzle according to an embodiment of the present invention includes:

[0111] Step 3: Based on the nozzle performance instability signal, the detection data of the pending nozzles after multiple tests are processed to obtain a pending evaluation value, and the value is compared with the threshold to analyze whether it is caused by abnormal detection operation;

[0112] In some embodiments, when a nozzle performance unstable signal is generated, pending nozzle detection data after multiple detections is processed, wherein the pending nozzle detection data includes a pressing time deviation value and a pressing depth deviation value, and the pressing time deviation value and the pressing depth deviation value are processed to obtain a pending evaluation value;

[0113] First, specifically, the method for obtaining the pressing time deviation value is as follows:

[0114] 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;

[0115] 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;

[0116] Subtract the end time node from the initial time node to get the pressing time value;

[0117] Obtaining the pressing time value after each detection of the perfume nozzle, and subtracting the pressing time value after each detection of the perfume nozzle from the preset pressing time to obtain a pressing time deviation value;

[0118] Calculate the ratio of the pressing time deviation value to the preset pressing time to obtain the pressing time deviation coefficient;

[0119] The pressing time deviation coefficients after multiple tests of the perfume nozzle are added and averaged to obtain the pressing time deviation degree value;

[0120] It is understood that the meaning of the press time deviation value is to reflect the average degree of deviation between the actual press time and the preset press time during multiple tests of the fragrance nozzle. Specifically, the larger the value, the greater the deviation between the actual press time and the preset press time during the test of the fragrance nozzle, and the nozzle performance unstable signal is caused by abnormal test operation. Conversely, the smaller the value, the smaller the deviation between the actual press time and the preset press time during the test of the fragrance nozzle, and the nozzle performance unstable signal is not caused by abnormal test operation.

[0121] The second specific method for obtaining the pressing depth deviation value is as follows:

[0122] 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;

[0123] Get the pressing depth corresponding to the position at the end of pressing the perfume nozzle, and mark it as the end pressing depth;

[0124] Subtract the final compression depth from the initial compression depth to obtain the compression depth value;

[0125] 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;

[0126] Calculate the ratio of the compression depth deviation value to the preset compression depth value to obtain the compression depth deviation coefficient;

[0127] The pressing depth deviation coefficients after multiple tests of the perfume nozzle are added and averaged to obtain the pressing depth deviation degree value;

[0128] It is understood that the depression depth deviation value represents the average degree of deviation between the actual depression depth of the fragrance nozzle and the preset depression depth value during multiple tests of the fragrance nozzle. Specifically, the larger the value, the greater the deviation between the actual depression depth and the preset depression depth during the test of the fragrance nozzle, indicating that the unstable nozzle performance signal is caused by an abnormal test operation. Conversely, the smaller the value, the smaller the deviation between the actual depression depth and the preset depression depth during the test of the fragrance nozzle, indicating that the unstable nozzle performance signal is not caused by an abnormal test operation.

[0129] The method for obtaining the pending assessment value is:

[0130] Obtaining a compression time deviation value and a compression depth deviation value, and summing the compression time deviation value and the compression depth deviation value to obtain a pending evaluation value;

[0131] It should be further clarified that the pending evaluation value represents a comprehensive quantitative assessment of the accuracy of the fragrance nozzle test evaluation, combining the two factors of the press time deviation value and the press depth deviation value. This value reflects the combined impact of the deviation between the actual press time and the preset press time, as well as the deviation between the actual press depth and the preset press depth, during multiple tests of the fragrance nozzle. Specifically, the larger the value, the greater the deviation between the press time and the preset values ​​during multiple tests of the fragrance nozzle, indicating that the unstable nozzle performance signal is caused by abnormal test operation. Conversely, the deviation between the press time and the preset values ​​during multiple tests of the fragrance nozzle is small, indicating that the unstable nozzle performance signal is not caused by abnormal test operation.

[0132] The pending evaluation value is compared with the pending evaluation threshold. The comparison process is as follows:

[0133] 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 deviated significantly from the preset values. Therefore, the nozzle performance instability signal is caused by abnormal testing operation.

[0134] If the pending evaluation value is less than or equal to the pending evaluation threshold, it indicates that during multiple tests of the perfume nozzle, both the pressing time and the pressing depth have little deviation from the preset values. Therefore, the nozzle performance instability signal is not caused by abnormal testing operation.

[0135] 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 value, and it is analyzed 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, and 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.
