Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of glue production, specifically to a glue detection method, production device and detection equipment based on visual detection. Background Art
[0002] Taking a published patent "A Method for Solving Glue Precipitation and Glue Mixing" (Publication No. CN116020296A) as Comparative Document 1, it is pointed out in Comparative Document 1 that glue is an intermediate connecting two materials, mostly in the form of aqueous solutions, belonging to the fine chemical industry, with a wide variety of types, mainly classified by adhesives, physical forms, hardening methods and the materials of the adherends.
[0003] Due to the reasons of glue production, substances such as particles and fillers are likely to remain inside the glue. In some glues with relatively low viscosity, the particles and fillers are prone to precipitate at the bottom. During the process of the glue discharging from the glue application equipment, the precipitated substances are likely to cause blockage of the glue outlet head, resulting in the inability to continue production and inaccurate glue discharge volume. Moreover, uneven fillers and particles will also affect the bonding effect.
[0004] Taking a published patent "A Stirring Device in the Synthesis of Plant Glue" (Publication No. CN207463025U) as Comparative Document 2, it is pointed out in Comparative Document 2 that the existing liquid stirring devices have uneven liquid mixing and cannot detect in real time whether the stirring is uniform during stirring.
[0005] Taking a published patent "Glue Detection Method, Device, Equipment and Medium Based on Visual Sensor Fly Shooting" (Publication No. CN114742827B) as Comparative Document 3, it is pointed out in Comparative Document 3 that using visual sensors such as area array cameras for glue defect detection (such as glue defect detection of OLED products) is a relatively common intelligent detection technology method. On the one hand, it can locate the product and the dispensing area; on the other hand, it can measure the size of the glue and detect various production index data of the glue.
[0006] Taking a published patent "Magnetic Conductive Glue and Its Application" (Publication No. CN102942886B) as Comparative Document 4, it is pointed out in Comparative Document 4 that in the preparation process of the magnetic conductive glue of the present invention, there is no special limitation on the addition order of each component. Usually at room temperature, the required amount of magnetic particles and optionally the required amount of nano-dispersion additives are added to the chemically curable glue, and then mixed evenly to obtain the magnetic conductive glue of the present invention.
[0007] In summary, in the prior art, when preparing glue (especially glue for special purposes), different materials (fillers and / or particles) need to be added to the glue to make the glue meet the requirements of different usage scenarios. During the preparation process, the glue needs to be fully stirred to ensure that the materials are evenly distributed in the glue to guarantee the overall production quality of the glue. However, the existing glue stirring devices cannot detect in real time whether the materials are evenly stirred during the stirring process. They can only mechanically perform timed operations based on the experience of the operators or extract samples of the stirred materials for detection. Among them, the timing of the timed operation is not easy to control. If the stirring time is too short, the stirring will be insufficient, affecting the production quality. If the stirring time is too long, it will affect the production efficiency and cause unnecessary cost waste. And extracting samples of the stirred materials for detection requires manual repeated detection operations, with low efficiency. Therefore, it is necessary to accurately detect in real time the uniformity of the materials in the glue during the stirring process to improve the production efficiency and quality of the glue.

[0059] Please refer to Figure 1-12 , a glue detection method based on vision detection, including a stirring module and a vision processing module;
[0060] The stirring module includes a rotating shaft component, on which a first paddle component and a second paddle component are successively fixed from top to bottom. A first installation port penetrating the front and rear end faces of the paddle is opened on the first paddle component, and a second installation port penetrating the front and rear end faces of the paddle is opened on the second paddle component;
[0061] The vision processing module includes a first motion camera component fixed in the first installation port and a second motion camera component fixed in the second installation port;
[0062] The operations of the vision processing module include the following steps:
[0063] S100: The first motion camera component performs fly shooting based on the first motion parameters to obtain a first picture group. The HSB color mode values corresponding to each pixel point of each picture in the first picture group are respectively obtained, and the pixel points satisfying the standard value in each picture in the first picture group are respectively accumulated and summed to obtain first arrays J1,..., Jn, where n≥2. Each element in the first array is respectively matched with the average value. When the number of elements in the first arrays J1,..., Jn that match the average value reaches the first threshold, step S200 is performed;
[0064] S200: The second sports camera component performs flying shooting based on the second motion parameters to obtain a second set of pictures, respectively obtains the HSB color mode values corresponding to each pixel point of each picture in the second set of pictures, and respectively accumulates and sums the pixel points that meet the standard value in each picture in the second set of pictures to obtain a second array K1, ……, Kn, where n≥2. Each element in the second array is respectively matched with the average value. When the number of elements in the second array K1, ……, Kn that match the average value reaches the second threshold, step S300 is performed;
[0065] S300: Merge the first array and the second array into a third array. When the number of elements in the third array J1, ……, Jn, K1, ……, Kn that match the average value reaches the third threshold, it is displayed that the current stirred material meets the target detection result;
[0066] Taking a publicly disclosed patent, a glue raw material melting and stirring device (publication number CN219816033U), as Comparative Document 5, it is pointed out in Comparative Document 5 that at present, in the production process of glue, a stirring device is required to uniformly mix various raw material components. The core structure of the stirring device in the prior art includes a rotating shaft and a plurality of blades fixed on the rotating shaft. The blades are driven by the rotating shaft to perform the stirring operation. In the present invention, the stirring module includes a first blade member and a second blade member that perform stirring operations at different levels in the vertical direction. The present invention can be applied to the stirring devices in the prior art;
[0067] During the stirring operation, the first blade member and the second blade member perform stirring operations in the stirred material (a mixture of glue and filler / particles). The stirred material respectively passes through the first installation port and the second installation port. The first sports camera component provided on the inner wall of the first installation port performs fixed-point and timed flying shooting sampling on the stirred material flowing through the first installation port, and the second sports camera component provided on the inner wall of the second installation port performs fixed-point and timed flying shooting sampling on the stirred material flowing through the second installation port, so that the detection of different layers in the stirred material can be conveniently carried out;
[0068] In S100, the first sports camera component performs flying shooting based on the first motion parameters to obtain a first set of pictures. The first motion parameters are the motion parameters of the first sports camera component. The first blade member drives the first sports camera component to rotate during the rotation process, such as Figure 1As shown, the operation of the first motion camera assembly is a circular motion centered around the rotating shaft member 220. The first blade member is fixedly arranged on the rotating shaft member 220. The rotation angle of the rotating shaft member 220 is the same as the rotation angle during the circular motion of the first motion camera assembly. By controlling the rotation angle of the rotating shaft member 220, the rotation angle of the first blade member and the rotation angle of the first motion camera can be controlled. The first motion parameters include an angle parameter and a time parameter. The angle parameter includes the predetermined rotation angle of the rotating shaft member 220 (the first motion camera assembly). When the rotating shaft member 220 rotates to the predetermined angle, shooting is performed. The time parameter includes the shooting time. After the stirring starts, the first motion camera assembly and the second motion camera assembly respectively perform flying shooting sampling at predetermined time intervals. In one embodiment, at a certain time point, when the rotating shaft member 220 rotates to the positions of 1 / 4, 2 / 4, 3 / 4, and 4 / 4 circles, the first motion camera assembly can respectively obtain flying shooting pictures of four determined target positions, forming the first picture group;
[0069] Respectively obtain the HSB color mode values corresponding to each pixel point of each picture in the first picture group. First, obtain the RGB primary color data corresponding to each pixel point in the area to be detected, and obtain the HSB color mode value corresponding to each pixel point according to the conversion relationship between the RGB primary color data and the HSB color mode value;
[0070] Respectively perform cumulative summation on the pixel points in each picture in the first picture group that meet the standard value. The HSB values of the parts of the stirred material containing fillers / particles are different from those of the parts without fillers / particles. Here, the standard value is the HSB value corresponding to the part of the stirred material containing fillers / particles, including the corresponding standard hue H, standard saturation S, and standard brightness B. The standard HSB value can be a range value. By comparing the HSB values corresponding to each pixel point of a single picture in the first picture group with the standard HSB value respectively, if the HSB value corresponding to a certain pixel point falls within the range of the standard HSB value, it means that the HSB value corresponding to this pixel point meets the standard value;
[0071] After the HSB values corresponding to each pixel point of each picture in the first picture group are judged in this way respectively, the number of pixel points whose HSB values meet the standard HSB value in each picture in the first picture group can be obtained, and the first arrays J1, ……, Jn are obtained, where n≥2. Here, the first arrays are variables that change over time. When the predetermined time arrives, the first arrays will obtain new values again. J1 is the number of pixel points whose HSB values meet the standard HSB value in the first picture in the first picture group, and Jn is the number of pixel points whose HSB values meet the standard HSB value in the nth picture in the first picture group. Calculate the number of quantities in the first arrays J1, ……, Jn that match the average value, where the average value = (J1 + …… + Jn) / n. Here, the matching can be a range interval. First, compare J1 with the average value to see if J1 matches the average value ……, and compare Jn with the average value to see if Jn matches the average value. The purpose of this is to calculate the difference degree among J1, ……, Jn. When the differences among J1, ……, Jn are relatively large, it indicates that the number of pixel points that meet the standard value in each picture in the first picture group varies greatly, indicating that the quantity of fillers / particles contained in each picture in the first picture group varies greatly, indicating that the stirring in the working area of the first paddle part is uneven. When the differences among J1, ……, Jn are relatively small, that is, J1, ……, Jn respectively match the average value, it indicates that the number of pixel points that meet the standard value in each picture in the first picture group varies little, indicating that the quantity of fillers / particles contained in each picture in the first picture group varies little, indicating that the stirring in the working area of the first paddle part is uniform. By controlling the matching accuracy, the detection accuracy can be controlled. For example, the number of pixel points that meet the standard value in the first picture is 96, and the average value is 100. When the matching accuracy is 95%, it indicates that the first picture matches the standard value. When the matching accuracy is 98%, it indicates that the first picture does not match the standard value. Therefore, by controlling the matching accuracy, the number of pictures reaching the first threshold can be controlled, thereby controlling the detection accuracy, that is, the higher the similarity among J1, ……, Jn, the more uniform the stirring in the working area of the first paddle part;
[0072] When the number of elements in the first arrays J1, ……, Jn that match the average value reaches the first threshold, where the first threshold can be a range of percentages. In one embodiment, the expected first threshold is set to 95% - 100%, which means that at least 95% of the elements in the first arrays J1, ……, Jn match the average value. This indicates that the stirring in the working area of the first blade member has achieved the expected effect and meets the production requirements. Similarly, by controlling the value of the first threshold, the detection accuracy can be controlled. For example, when the first threshold is 99%, it means that 99% of the picture similarities in the first picture group match the average value. When the first threshold is 91%, it means that 91% of the picture similarities in the first picture group match the average value. Therefore, by controlling the value of the first threshold, the fineness of the detection can be controlled. At a certain point in time, when the number of elements in the first arrays J1, ……, Jn that match the average value reaches the first threshold, it indicates that on the planar dimension where the first blade member is located, the stirring uniformity of the glue has reached the expected value;
[0073] In S200, the working principle of the second moving camera component is the same as that of the first moving camera component. When the number of elements in the second arrays K1, ……, Kn that match the average value reaches the second threshold, it indicates that on the planar dimension where the second blade member is located, the stirring uniformity of the glue has reached the expected value;
[0074] In S300, since the first mounting port and the second mounting port are located on different levels vertically, it is convenient to obtain the measurement data at different positions in the glue, making the obtained measurement data more comprehensive and accurate. Calculate the number of elements in the third arrays J1, ……, Jn, K1, ……, Kn that match the average value. The principle is the same as that of the first moving camera component, and the purpose is to calculate the difference degree between J1, ……, Jn, K1, ……, Kn. When the number of elements in the third arrays J1, ……, Jn, J1, ……, Jn that match the average value reaches the third threshold, where the average value = (J1, ……, Jn + J1 + …… + Jn +) / 2n, it means that the stirring in the working areas of the first blade member and the second blade member both tend to be uniform and equal. That is, at a certain point in time, the uniformity of the upper layer (the layer where the first blade member is located) and the lower layer (the layer where the second blade member is located) of the stirred material tends to be consistent, which means that the uniformity in the vertical dimension of the stirred material also tends to be consistent. Through the comprehensive measurement of multiple planar dimensions and one vertical dimension, the overall uniformity of the stirred material can be more comprehensively reflected;
[0075] The present invention adopts the cooperation of the first motion camera assembly and the second motion camera assembly. Through the comprehensive measurement of multiple planar dimensions and one vertical dimension, the overall uniformity of the stirred material can be detected quickly in real time. By controlling the matching accuracy and the size of the threshold, the fineness in the production process can be intuitively controlled, making the product quality control more convenient and accurate. At the same time, the uniformity of the stirred material can be fed back in real time, and the production progress can be viewed in real time, so as to facilitate the staff to more accurately control the stirring time, improve the production efficiency, be convenient for fixed installation, be fully digitalized and automated in operation, have strong stability, have high practicability, and improve the production efficiency and quality of glue.
[0076] In the embodiment of the present invention, the first motion parameter includes a first time parameter. The first time parameter includes a time array T1, ……, Tn composed of the shooting time intervals of the first motion camera assembly each time calculated from the start of stirring. n≥2. After the stirring operation starts, the first motion camera assembly and the second motion camera assembly perform shooting operations according to the first time array.
[0077] The second motion parameter includes a second time parameter synchronized with the first time parameter.
[0078] In the actual production process, T1 is the time interval from the start of stirring to the first shooting operation of the first motion camera assembly. After an interval of T2 time, the first motion camera assembly takes a flying shot for sampling again. After an interval of T3 time, the first motion camera assembly takes a flying shot for sampling again, and so on. The more the number of elements in the time array, the more times the shooting value of the first motion camera assembly is taken. Because the movements of the first paddle member and the second paddle member are synchronized, the second motion parameter includes a second time parameter synchronized with the first time parameter.
[0079] In the embodiment of the present invention, in the first time array T1, ……, Tn, T1>T2>……>Tn;
[0080] After the start of stirring, as time increases, the uniformity of each part of the stirred material gradually tends to be consistent. At this time, the uniformity of the stirred material may reach the target requirement at any time. In order to more accurately determine the time point when the stirred material meets the target detection result, as the stirring time increases, the measurement interval time of the first motion camera assembly is shortened to more quickly determine the time point when the stirred material meets the target detection result. In one embodiment, the first time array includes 20min, 10min, 5min, 2min, 1min. As time increases, the measurement frequency increases, which can increase the measurement efficiency and better meet the actual requirements.
[0081] In the embodiments of the present invention, the first motion parameter further includes a first angle parameter. The first angle parameter includes a first angle array α1, ……, αn composed of the angles of rotation of the rotating shaft member 220, where n≥2. Each element of the first arrays J1, ……, Jn corresponds and cooperates with each element of the first angle array α1, ……, αn in sequence;
[0082] The second motion parameter further includes a second angle parameter synchronized with the first angle parameter;
[0083] When reaching a predetermined time point, when the rotating shaft member 220 rotates by angles α1, ……, αn respectively, the first motion camera assembly takes pictures respectively. At this time, the first blade member rotates by angles α1, ……, αn respectively, and the first motion camera assembly rotates by angles α1, ……, αn respectively. The more the number of elements in the angle array, the more times the shooting values of the first motion camera assembly are taken, the larger the number of pictures included in the first picture group, the more numerical values included in the first array, and the more detailed and accurate the detection result. Because the movements of the first blade member and the second blade member are synchronized, the second motion parameter includes a second angle parameter synchronized with the first angle parameter.
[0084] In the embodiments of the present invention, in the first angle array α1, ……, αn, α1 = …… = αn;
[0085] By making α1 = …… = αn, the circular motion of the first motion camera assembly can be evenly divided, making the measurement result more comprehensive and stable, and making the detection result more accurate.
[0086] In the embodiments of the present invention, in the first angle array α1, ……, αn, the first angle array at time point Tn is complementary to the first angle array at time point Tn - 1;
[0087] At time points T1 and T2, the angles of the first angle array change, and the first angle array at time point T1 is complementary to the first angle array at time point T2. As Figure 2 shown, in one embodiment, at time point T1, the first angle array includes 1 / 8, 3 / 8, 5 / 8, 7 / 8 circles, and at time point T2, the first angle array includes 1 / 4, 2 / 4, 3 / 4, 4 / 4 circles. The first angle arrays at different time points tend to be complementary and cover the plane where the motion path of the first motion camera assembly is located, making the detection result of the present invention more comprehensive, more stable and accurate.
[0088] In the embodiments of the present invention, the first installation port includes a first vertical port 001 arranged vertically and a first horizontal port 002 arranged horizontally. The first motion camera assembly includes a first vertical camera member arranged vertically in the first vertical port 001 and a first horizontal camera member arranged horizontally in the first horizontal port 002;
[0089] The second installation port includes a second vertical port arranged vertically and a second horizontal port arranged horizontally. The second motion camera assembly includes a second vertical camera member arranged vertically in the second vertical port and a second horizontal camera member arranged horizontally in the second horizontal port;
[0090] In one embodiment, during the actual detection of the stirred material, the glue flowing through the first installation port (the operation of the second installation port is the same as that of the first installation port, which will not be elaborated here) exists in a three-dimensional form. In one embodiment, as Figure 3 shown, where the dotted arrow indicates the flow direction of the stirred material in the first installation port. The first motion camera assembly is arranged along the Z-axis and / or Y-axis to take pictures of the stirred material flowing through the first installation port. Suppose Figure 3 the X-axis and Y-axis coordinates of Q1 and Q2 are the same, and the X-axis and Z-axis coordinates of Q2 and Q3 are the same. When the stirred material flows through the first installation port, due to the three-dimensional flow path, during the shooting process of the first motion camera assembly, some of the fillers / particles will overlap in space (such as Q1, Q2, Q3);
[0091] Taking the publicly disclosed patent CN214410073U as Comparative Document 6, the operation mode of an industrial camera is described in Comparative Document 6. The image data information collected by the industrial camera is mainly color information and external ambient light information. The industrial camera uses a visible light camera capable of collecting two-dimensional images and relative angles of the object to be measured in the scene. Specifically, this industrial camera has an independent data processing unit, and based on the collected color image, the planar coordinates and relative angles of the object to be measured in the scene can be determined. The industrial camera detects the planar coordinates and relative angle information of the object to be measured in the scene. It can be seen from Comparative Document 6 that the industrial camera generally can only obtain planar color information and coordinate information, lacking the support of three-dimensional information, and requires the cooperation of personnel or three-dimensional detection equipment to perform three-dimensional detection. Therefore, it is difficult to avoid the problem of repeated stacking of fillers / particles in the first installation port, which affects the measurement results;
[0092] Such as Figure 4 and Figure 5As shown, a first vertical camera component is vertically arranged in the first vertical port 001. The first vertical camera component is embedded in the inner bottom surface of the first vertical port 001. Through the first vertical camera component, the stirred material flowing through the first vertical port 001 is photographed. In the actual production process, by controlling the width of the first vertical port 001, the thickness of the stirred material flowing through the first vertical port 001 can be made thin enough, so that the problem of repeated stacking of fillers / particles can be greatly reduced, making the detection result of the present invention more accurate. A first horizontal camera component is horizontally arranged in the first horizontal port 002. Through the first horizontal camera component, the stirred material flowing through the first horizontal port 002 is photographed. In the actual production process, by controlling the width of the first horizontal port 002, the thickness of the stirred material flowing through the first horizontal port 002 can be made thin enough, so that the problem of folding of fillers / particles in the horizontal direction can be greatly reduced, and the stirred material is sampled in a plane stratification similar to planarization, making the shooting effects of the first horizontal camera component and the first vertical camera component better, and making the detection result of the present invention more accurate. The operations of the second horizontal camera component and the second vertical camera component are the same as those of the first horizontal camera component and the first vertical camera component, and will not be elaborated here.
[0093] In the embodiment of the present invention, S100 includes the following steps:
[0094] S110: The first picture group includes the first vertical picture groups A1,..., An photographed by the first vertical camera component, where n≥2 and n is an integer;
[0095] The pixel points meeting the standard value in A1,..., An are respectively accumulated and summed to obtain the first vertical arrays SA1,..., SAn. Each element in the first vertical arrays is respectively matched with the average value. When the number of elements in SA1,..., SAn matching the average value reaches the first threshold, step S120 is performed;
[0096] S120: The first picture group further includes the first horizontal picture groups a1,..., an photographed by the first horizontal camera component, where a1 is synchronized with A1,..., an is synchronized with An;
[0097] The pixel points meeting the standard value in a1,..., an are respectively accumulated and summed to obtain the first horizontal arrays Sa1,..., San. Each element in the first horizontal arrays is respectively matched with the average value. When the number of elements in Sa1,..., San matching the average value reaches the first threshold, step S210 is performed;
[0098] S200 includes the following steps:
[0099] S210: The second picture group includes the second vertical picture groups B1,..., Bn photographed by the second vertical camera component, where n≥2 and n is an integer;
[0100] Accumulate and sum up the pixel points that meet the standard value in B1, ……, Bn respectively to obtain the second vertical arrays SB1, ……, SBn. Match each element in the second vertical arrays with the average value respectively. When the number of elements in SB1, ……, SBn that match the average value reaches the second threshold, then perform step S220;
[0101] S220: The second picture group further includes the second horizontal picture groups b1, ……, bn taken by the second horizontal camera device, where b1 is synchronized with B1, ……, bn is synchronized with Bn;
[0102] Accumulate and sum up the pixel points that meet the standard value in b1, ……, bn respectively to obtain the second horizontal arrays Sb1, ……, Sbn. Match each element in the second horizontal arrays with the average value respectively. When the number of elements in Sb1, ……, Sbn that match the average value reaches the second threshold, then perform step S310;
[0103] S300 includes the following steps:
[0104] S310: The third array includes the combination of the first vertical array, the first horizontal array, the second vertical array and the second horizontal array. When the number of elements in the third arrays SA1, ……, SAn, Sa1, ……, San, SB1, ……, SBn, Sb1, ……, Sbn that match the average value reaches the third threshold, it is displayed that the current mixture meets the target detection result;
[0105] The mixture flows through the first vertical port 001, the first horizontal port 002, the second vertical port and the second horizontal port, the first vertical camera device, the first horizontal camera device, the second vertical camera device and the second horizontal camera device respectively. By performing snapshot shooting on the mixture flowing through the first vertical port 001, the first horizontal port 002, the second vertical port and the second horizontal port respectively, the measurement accuracy is improved. Each step is carried out in sequence, which can simplify the process. In S110, when the number of elements in SA1, ……, SAn that match the average value does not reach the first threshold, it will not jump to S120, thus saving computing power.
