Description

Technical Field

[0001] This application relates to the field of adhesive production technology, and in particular to a vision-based adhesive production degassing device, method and system. Background Technology

[0002] Water-based adhesives are prone to air entrapment during stirring and mixing. Residual air bubbles can cause poor insulation, bonding voids, and optical defects in bonded products. Currently, commonly used degassing methods include natural degassing, centrifugal degassing, and conventional vacuum degassing. However, these methods generally suffer from low degassing efficiency. For example, natural degassing relies on the passive floating of air bubbles, resulting in a long processing cycle; centrifugal degassing has limited capacity and cannot be adapted to mass production; and for high-viscosity adhesives, traditional static vacuum degassing suffers from high resistance to microbubble precipitation, slow discharge speed, and prolonged degassing time.

[0003] In summary, existing glue degassing technologies suffer from problems such as slow degassing speed, low yield, and poor mass production capabilities, failing to meet actual production needs. Summary of the Invention

[0005] According to a first aspect of the embodiments of this application, a vision-based degassing device for adhesive production is provided. The device includes a cylinder and a conveying assembly, a stirring assembly, a heating assembly, a vision assembly, and a vacuuming assembly connected to the cylinder.

[0010] The vacuum assembly is used to adjust the vacuum level inside the cylinder when degassing the adhesive mixture.

[0011] It also includes a control component connected to the stirring component, the heating component, the vision component, and the vacuuming component. The control component is used to determine the actual bubble diameter in the adhesive mixture based on the image captured by the vision component during the degassing process of the adhesive mixture, and to control the stirring speed of the stirring component and the vacuuming speed of the vacuuming component based on the actual bubble diameter, so as to increase the size of the actual bubble diameter.

[0014] The actual bubble diameter is compared with the minimum bubble diameter and the maximum bubble diameter, respectively;

[0015] If the actual bubble diameter is smaller than the minimum bubble diameter, the stirring speed of the stirring component is controlled to be low, and the vacuuming speed of the vacuuming component is controlled to be maximum.

[0016] If the actual bubble diameter is greater than or equal to the minimum bubble diameter and less than the maximum bubble diameter, the stirring speed of the stirring component is controlled to be low, and the vacuuming speed of the vacuuming component is reduced according to the difference between the actual bubble diameter and the maximum bubble diameter.

[0028] When the stirring assembly operates at maximum stirring speed for a first preset time, the control assembly compares the actual bubble diameter with the bubble diameter limit. If the actual bubble diameter is smaller than the bubble diameter limit, the vacuuming speed of the vacuuming assembly is determined based on the difference between the actual bubble diameter and the bubble diameter limit, and the vacuuming assembly is controlled at the determined vacuuming speed. If the actual bubble diameter is greater than or equal to the bubble diameter limit, the pressure stabilizing assembly is controlled to pressurize the inside of the cylinder to reduce the vacuum level inside the cylinder.

[0029] In some embodiments, the glue production degassing device further includes a cooling component disposed on the outside of the cylinder;

[0030] After pressurization is completed, if the actual bubble diameter is greater than or equal to the bubble diameter limit, the heating component is turned off, and the cooling component is controlled to reduce the temperature of the adhesive mixture.

[0031] In some embodiments, when the actual bubble diameter is less than the minimum bubble diameter, if the control component determines that the duration for which the actual bubble diameter is less than the minimum bubble diameter is greater than a second preset duration, then the control component controls the vacuuming component to adjust the vacuum level to the maximum value, and controls the stirring component to stir at a low speed and in an intermittent stirring mode.

[0032] In some embodiments, if the control component determines that no bubbles are generated for a third preset time, it determines that degassing is complete.

[0034] In response to the received defoaming command, the control component determines the actual bubble diameter in the adhesive mixture based on the image captured by the vision component.

[0035] The control component controls the stirring speed of the stirring component and the vacuuming speed of the vacuuming component based on the actual bubble diameter, so as to increase the size of the actual bubble diameter.

[0036] According to a third aspect of the embodiments of this application, a vision-based degassing system for adhesive production is provided, comprising the vision-based degassing device for adhesive production described in the first aspect and a cloud server, wherein the cloud server is used to send degassing instructions to the vision-based degassing device for adhesive production.

[0048] The specific implementation of the embodiments of this application will be further described below with reference to the accompanying drawings.

[0049] See Figure 1-2The diagram shown is a schematic of the structure of a vision-based degassing device for glue production provided in an embodiment of this application. The device specifically includes a cylinder 1 and a material conveying assembly 3, a stirring assembly 2, a heating assembly 10, a vision assembly, a vacuuming assembly 8, and a support assembly 11 connected to the cylinder.

[0050] Among them, the support component 11 is used to support the vision-based glue production degassing device.

[0051] The material conveying assembly 3 is disposed on the side wall of the cylinder 1 and is used to input the adhesive raw material into the cylinder 1. The material conveying assembly 3 may specifically include a first material conveying pipe 31, a material conveying motor 32, and a second material conveying pipe 33. Specifically, the material conveying assembly 3 may be disposed at the top or bottom of the side wall of the cylinder 1, so as to convey the adhesive raw material into the cylinder 1.

[0052] The stirring assembly 2 is installed inside the cylinder 1 to stir the glue mixture inside the cylinder 1 to produce glue. The stirring assembly 2 may specifically include a stirring rod 21 and a stirring shaft 22. One end of the stirring shaft 22 is connected to the stirring motor 4, and the other end is connected to the stirring rod 21, so that the stirring motor 4 can drive the stirring assembly 2 to stir the glue mixture inside the cylinder 1.

[0053] In one example, the stirring rod 21 can be directly connected to the stirring shaft 22, or it can be connected to the stirring shaft 22 via a turntable. Specifically, the turntable can be set on the stirring shaft 22, and the stirring rod 21 can be set on the turntable.

[0054] Heating components 10 are mounted on the cylinder 1 and are used to heat the adhesive mixture inside the cylinder 1. Specifically, multiple heating components 10 can be provided. Specifically, the preset temperature in this embodiment can be 50°C, or other values, which can be selected according to the composition and viscosity of the adhesive.

[0055] The vision components specifically include a first vision component 6 and a second vision component 7. The first vision component 6 is disposed on the cover plate 5 at the top of the cylinder 1 and is used to capture an image of the liquid surface of the glue mixture. This liquid surface image is used to determine the actual bubble diameter on the surface of the glue mixture. The first vision component 6 specifically includes a first housing 61, a first industrial camera 62, and a first light source 63. The first light source 63 is used to provide supplementary lighting when the first industrial camera 62 captures the liquid surface image of the glue mixture to improve the clarity of the captured image, thereby improving the accuracy of identifying the actual bubble diameter. The second vision component 7 is disposed on the side wall of the cylinder 1 and is used to capture a side image of the glue mixture. This side image is used to determine the rising speed of the bubbles in the glue mixture. The second vision component 7 specifically includes a second housing 71, a second industrial camera 72, and a second light source 73. The second light source 73 is used to provide supplementary lighting when the second industrial camera 72 captures the side image of the glue mixture to improve the clarity of the captured image, thereby improving the accuracy of identifying the actual bubble rising speed.

[0056] The vacuum pumping assembly 8 is disposed on the side wall of the cylinder 1, specifically above the side wall of the cylinder 1, and is used to evacuate the inside of the cylinder 1. The vacuum pumping assembly 8 may specifically include a vacuum pump 81 and a pressure gauge 82, wherein the vacuum pump 81 is used to evacuate the inside of the cylinder 1, and the pressure gauge 82 is used to calculate the vacuum level inside the cylinder 1.

[0057] The control component (not shown in the figure) is connected to the stirring component 2, the heating component 10, the vision component, and the vacuuming component 8 respectively. During the degassing process of the glue mixture, it determines the actual bubble diameter in the glue mixture based on the image captured by the vision component, and controls the stirring speed of the stirring component 2 and the vacuuming speed of the vacuuming component 8 based on the actual bubble diameter to increase the size of the actual bubble diameter.

[0058] Specifically, the control component determines the actual bubble size based on the liquid surface image captured by the first vision component 6, and controls the stirring speed of the stirring component 2 and the vacuuming speed of the vacuuming component 8 based on the actual bubble diameter, so as to increase the actual bubble diameter.

[0059] In one example, the vision-based glue production degassing device of this application also includes a discharge port (not shown in the figure), through which the glue is taken out and filled when degassing is completed.

[0060] The vision-based degassing device for adhesive production provided in this application embodiment can degas adhesive mixtures. By setting up a vision component and a control component, the control component determines the actual bubble diameter based on the image captured by the vision component during the degassing process. Based on the actual bubble diameter, the control component controls the stirring speed of the stirring component and the vacuuming speed of the vacuuming component, thereby increasing the actual bubble diameter, effectively increasing the degassing speed, improving the degassing efficiency, and reducing the degassing time.

[0061] Furthermore, the bubble diameter in this embodiment includes a minimum bubble diameter and a maximum bubble diameter. The maximum bubble diameter is used to represent the bubble boiling state. When the actual bubble diameter is greater than or equal to the maximum bubble diameter, it indicates that the bubble is about to enter a boiling state. Specifically, when the control component controls the stirring speed of the stirring component 2 and the vacuuming speed of the vacuuming component 8 according to the actual bubble diameter, it first acquires the liquid surface image captured by the first vision component 6, identifies the actual bubble diameter in the image according to a preset image algorithm, and compares the actual bubble diameter with the minimum bubble diameter and the maximum bubble diameter, respectively.

[0062] Specifically, if the control component determines that the actual bubble diameter is less than the minimum bubble diameter, it determines that the degassing efficiency is low. Therefore, it controls the stirring speed of the stirring component to low and the vacuuming speed of the vacuuming component to maximum, thereby rapidly increasing the actual bubble diameter to improve degassing efficiency. If the control component determines that the actual bubble diameter is greater than or equal to the minimum bubble diameter but less than the maximum bubble diameter, it determines that the degassing efficiency is low and the bubble diameter growth rate needs to be controlled to prevent excessively rapid growth leading to a violent boiling state. Therefore, the control component controls the stirring speed of the stirring component 2 to low and reduces the vacuuming speed of the vacuuming component based on the difference between the actual bubble diameter and the maximum bubble diameter. If the control component determines that the actual bubble diameter is greater than or equal to the maximum bubble diameter, it determines that a violent boiling state is about to occur. Therefore, the control component controls the stirring component 2 to operate at its maximum stirring speed and controls the vacuuming component 8 to maintain the current vacuum level, thereby reducing the actual bubble diameter through the shear force of the stirring component 2 and preventing a violent boiling state.

[0063] In one example, the minimum bubble diameter can be 5 mm, and the maximum bubble diameter can be 15 mm. The mixing speed of the mixing component 2 includes low, medium, and high speeds, with the low speed range being 10-40 rpm, the medium speed range being 41-80 rpm, and the high speed range being 81-120 rpm. The specific rpm for low, medium, and high speeds can be determined based on the viscosity of the adhesive mixture.

[0064] In one example, the preset image algorithm in this application embodiment can be a prior art semantic segmentation algorithm, convolutional neural network, etc., as long as it can achieve the bubble diameter.

[0065] In the degassing process, the control component of this application determines the current degassing efficiency by comparing the actual bubble diameter with the minimum and maximum bubble diameter values. When the actual bubble diameter is less than the minimum bubble diameter, the vacuum component is controlled to operate at maximum speed to quickly increase the actual bubble size, thereby rapidly improving the degassing efficiency. When the actual bubble diameter is greater than or equal to the minimum bubble diameter but less than the maximum bubble diameter value, the control component controls the stirring speed of the stirring component to be low, and reduces the vacuuming speed of the vacuum component based on the difference between the actual bubble diameter and the maximum bubble diameter value. This controls the rate of bubble diameter growth, preventing excessively rapid growth that could lead to violent boiling. This ensures both degassing safety and high degassing efficiency. When the actual bubble diameter is greater than or equal to the maximum bubble diameter value, the stirring component is controlled to operate at maximum speed, and the vacuum component is controlled to maintain the current vacuum level, preventing violent boiling. This ensures both degassing safety and high degassing efficiency.

[0066] Furthermore, when the control component reduces the vacuuming speed of the vacuuming component based on the difference between the actual bubble diameter and the bubble diameter limit, the control component first acquires two adjacent frames of liquid surface images captured by the first vision component 6, and determines the actual bubble growth rate based on the difference in the actual bubble diameter in the two adjacent liquid surface images. Furthermore, the actual bubble growth rate is compared with the preset value corresponding to the actual growth rate, and then the vacuuming speed of the vacuuming component 8 can be controlled according to the bubble growth rate.

[0067] Specifically, if the control component determines that the actual growth rate is greater than or equal to the preset value, the control component determines that the bubble growth rate is too high and is prone to boiling. Therefore, the control component quickly reduces the vacuuming speed based on the difference between the actual bubble diameter and the bubble diameter limit value and the actual growth rate. If the control component determines that the actual growth rate is less than the preset value, the control component determines that the bubble growth rate is within the safe range. Therefore, the control component slowly reduces the vacuuming speed based on the difference between the actual bubble diameter and the bubble diameter limit value.

[0068] In one example, the preset value corresponding to the actual growth rate can be 5 mm / s.

[0069] In this embodiment, when improving degassing efficiency, the control component compares the actual bubble growth rate with a preset value corresponding to the actual growth rate to determine whether boiling over will occur during the degassing process. If the actual growth rate is greater than or equal to the preset value, the control component determines that the bubble growth rate is too high and boiling over is likely to occur. At the same time, it rapidly reduces the vacuuming speed based on the difference between the actual bubble diameter and the bubble diameter limit and the actual growth rate, thereby avoiding boiling over and ensuring the safety of the degassing process. If the control component determines that the actual growth rate is less than the preset value, the control component determines that the bubble growth rate is within a safe range, and slowly reduces the vacuuming speed based on the difference between the actual bubble diameter and the bubble diameter limit.

[0070] Furthermore, the method of reducing the vacuuming speed based on the difference between the actual bubble diameter and the limit value of the bubble diameter and the actual growth rate in this embodiment can be expressed as follows:

[0071]

[0072] The vacuuming speed is reduced based on the difference between the actual bubble diameter and the limit value of the bubble diameter, which can be expressed as:

[0073]

[0074] Where V is the actual vacuum pumping speed. Where D is the maximum vacuum pumping speed, and D is the actual bubble diameter. Minimum bubble diameter Let be the limit value for bubble diameter, and α be a nonlinear exponent ranging from 1 to 2. For control coefficients, This represents the actual growth rate. Specifically, The value can range from 1 to 15, and its value is positively correlated with the viscosity of the glue mixture.

[0075] Furthermore, when the control component determines that the actual growth rate is less than a preset value, it simultaneously acquires a side image of the adhesive mixture captured by the second vision component 7. Based on two adjacent side images, it determines the bubble rising speed and then determines a method to reduce the vacuuming speed based on the bubble rising speed. If the control component determines that the bubble rising speed is greater than the preset maximum bubble rising speed, it determines that a boiling-out situation is likely to occur. Therefore, the control component reduces the vacuuming speed based on the difference between the actual bubble diameter and the bubble diameter limit and the actual growth rate; conversely, it reduces the vacuuming speed based on the difference between the actual bubble diameter and the bubble diameter limit.

[0076] In one example, the preset value for the bubble rising speed can be 5mm / s-15mm / s. The preset value for the bubble rising speed can be set according to the actual viscosity of the glue, and the preset value for the bubble rising speed is negatively correlated with the viscosity of the glue.

[0077] In one example, multiple second vision components 7 can be configured to improve the accuracy of bubble rising speed recognition.

[0078] For further information, please refer to [link / reference]. Figure 1 As shown, the glue production degassing device in this embodiment of the application further includes a pressure stabilizing component 9. The pressure stabilizing component 9 is connected to the cylinder 1 and is disposed above the cylinder 1. It is used to supply gas to the cylinder 1 to increase the pressure inside the cylinder 1. Specifically, the pressure stabilizing component 9 may include a pressure stabilizing bottle 91 and a solenoid valve 92. The pressure stabilizing bottle 91 contains an inert gas, specifically helium.

[0079] Specifically, when the control component determines that the actual bubble diameter is greater than or equal to the bubble diameter limit and controls the stirring component 2 to run at its maximum stirring speed, the control component obtains the running time of the stirring component 2 at its maximum stirring speed. When the running time reaches the first preset duration, the control component compares the actual bubble diameter with the bubble diameter limit again. If the control component determines that the actual bubble diameter is less than the bubble diameter limit, the control component determines that boiling will not occur. Therefore, based on the difference between the actual bubble diameter and the bubble diameter limit, the control component determines the vacuuming speed of the vacuuming component to continue to increase the degassing efficiency and controls the vacuuming component at the determined vacuuming speed. If the control component determines that the actual bubble diameter is greater than or equal to the bubble diameter limit, the control component determines that boiling is likely to occur. Therefore, the control component controls the pressure stabilizing component to pressurize the inside of the cylinder to reduce the vacuum inside the cylinder, thereby quickly reducing the actual bubble diameter and avoiding boiling.

[0080] In one example, when the control component controls the pressure stabilizing component 9 to pressurize the inside of the cylinder 1, the control solenoid valve 92 is used to pressurize intermittently, with a maximum pressurization time of 2 minutes, thereby avoiding drastic pressure changes inside the cylinder 1. At the same time, the running time can be set to 1 minute for the first preset duration.

[0081] In this embodiment, when the control component determines that the actual bubble diameter is greater than or equal to the bubble diameter limit and controls the stirring component 2 to run at its maximum stirring speed, it can determine whether the shearing method has successfully prevented boiling. If the actual bubble diameter is still greater than or equal to the bubble diameter limit, the control component determines that the shearing method has failed to prevent boiling and controls the pressure stabilizing component to pressurize the cylinder to quickly reduce the actual bubble size, thereby preventing boiling and improving the safety of the degassing process.

[0082] Furthermore, the glue production degassing device in this embodiment of the application also includes a cooling component (not shown in the figure). The cooling component is disposed on the outside of the cylinder. After the control component controls the pressure stabilizing component 9 to pressurize, the control component compares the actual bubble diameter with the bubble diameter limit value for the third time. When it is determined for the third time that the actual bubble diameter is greater than or equal to the bubble diameter limit value, the control component turns off the heating component and controls the cooling component to reduce the temperature of the glue mixture, so as to reduce the rising speed of the bubbles in the glue mixture, thereby helping to reduce the actual bubble size, thereby avoiding boiling and further ensuring the safety of degassing.

[0083] Furthermore, when the control component determines that the actual bubble diameter is less than the minimum bubble diameter, the control component acquires the duration of this state. When the duration for which the control component determines that the actual bubble diameter is less than the minimum bubble diameter is greater than the second preset duration, the control component determines that the removal of large bubbles is complete. At the same time, the control component adjusts the vacuum level of the vacuum pumping component to the maximum value and controls the stirring component to stir at a low speed and in an intermittent stirring mode to remove small bubbles. The intermittent period of the stirring component 2 provides a completely undisturbed pure buoyancy rising channel for the microbubbles, and the maximum vacuum level can remove small bubbles at the fastest speed.

[0084] Furthermore, if the control component determines that no bubbles are generated, the control component obtains the actual time when no bubbles are generated. If the actual time when no bubbles are generated reaches the third preset duration, the degassing is determined to be complete.

[0085] In one example, the third preset duration can be set to 1 minute.

[0086] Furthermore, such as Figure 3 As shown in the flowchart of the vision-based degassing method for adhesive production provided in this application embodiment, applied to the vision-based degassing device for adhesive production in this application embodiment, the method includes:

[0087] S301, the control component responds to the received defoaming command and determines the actual bubble diameter in the adhesive mixture based on the image captured by the vision component;

[0088] S303, the control component controls the stirring speed of the stirring component 2 and the vacuuming speed of the vacuuming component 8 according to the actual bubble diameter, so as to increase the size of the actual bubble diameter.

[0089] Furthermore, such as Figure 4 The diagram shown is a schematic of the structure of a vision-based degassing system for glue production provided in this application embodiment. The system includes a vision-based degassing device for glue production and a cloud server, and the cloud server is used to send degassing instructions to the vision-based degassing device for glue production.
