[0033] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The invention provides a metering, mixing and degassing control method for liquid silicone, which is used to solve the problem in the prior art that the degassing efficiency of liquid silicone is low and affects the production process.

[0035] See also Figure 1 , Figure 1 The present invention provides a first flow chart of a method for controlling metering, mixing and degassing of liquid silicone rubber according to an embodiment of the present invention.

[0036] S100, receiving a power-on signal, and setting two degassing chambers in the current degassing device to the minimum negative pressure value and the maximum negative pressure value of the degassing machine respectively; identifying the degassing state of the degassing device based on image processing, and obtaining the first degassing time and the second degassing time corresponding to the chambers with the minimum negative pressure value and the maximum negative pressure value;

[0037] It should be noted that AB glue is another name for two-liquid mixed hardening glue. It is necessary to mix the glue as A glue and the hardener as B glue to form silica gel. The A component is generally acrylic modified epoxy or epoxy resin, or contains catalysts and other additives, and the B component is generally modified amine or other hardeners, or contains catalysts and other additives, and they are mixed in a certain proportion; please refer to Figure 2 In the degassing and mixing system adopted in this embodiment, two degassing devices are arranged for degassing the colloid of component A and component B respectively. Two degassing chambers are arranged in each degassing device 1, namely, the first degassing chamber 2 and the second degassing chamber 3. The degassing chamber can be evacuated to form a negative pressure so that the bubbles inside the colloid are separated faster. When one degassing chamber is degassing under negative pressure, the other degassing chamber is used for feeding, and the two work alternately to ensure the continuous operation of the silica gel injection. The current degassing device can be a degassing device corresponding to either component A or component B.

[0038] The negative pressure in the degassing chamber is adjustable. This step only sets the parameters of the degassing device of one component, and sets the two chambers of the degassing device with the maximum and minimum values ​​of the adjustable negative pressure interval respectively. Because the negative pressure is a negative pressure, the pressure difference between the inside and outside of the colloid bubble is greater at the minimum negative pressure, and the degassing rate is faster. The pressure difference between the inside and outside of the colloid bubble is smaller at the maximum negative pressure, and the degassing rate is slower. By acquiring the image of the colloid in the degassing chamber for image processing, after determining that the number of bubbles is less than a threshold number, the colloid in the degassing device is deemed to have completed degassing, and the time length between the start of degassing and the time point when the number of bubbles is less than the threshold number is recorded as the degassing time. The minimum negative pressure degassing is faster and the first degassing time is shorter, and the maximum negative pressure degassing is slower and the second degassing time is longer.

[0039] S200, obtaining the colloid mass in the degassing chamber with the maximum negative pressure and the degassing chamber with the minimum negative pressure in the degassing device, obtaining the first colloid mass and the second colloid mass, substituting the data into the degassing negative pressure setting model, and obtaining the degassing negative pressure setting value, wherein the degassing negative pressure setting model is specifically:

[0040]

[0041] Where m1 is the mass of the first colloid, m2 is the mass of the second colloid, t1 is the first degassing time, t2 is the second degassing time, ΔP is the negative pressure difference of the chamber, P max is the maximum negative pressure adjustment value, P2 is the maximum negative pressure value, Q is the flow rate of the colloid injection in the current degassing device, P s is the degassing negative pressure setting value, a is the chamber replacement buffer coefficient;

[0042] It should be noted that the viscosity of AB colloidal components is different and the degassing speed is also different. In the case of proportional supply of silica gel for injection, the consumption is also different. In order to ensure that the colloids of the two components can be continuously supplied for injection, the two chambers in the degassing device of each component need to be able to work seamlessly, that is, when the colloid supply in one degassing chamber is consumed, the colloid in the other chamber has completed degassing, and the degassing speed needs to be greater than or equal to the supply speed to ensure continuous injection supply.

[0043] The degassing speed is related to the negative pressure value and the mass of the degassing colloid. After the bubbles are generated, they will be evenly distributed in the colloid. Under the condition of constant density, the larger the mass, the larger the volume of the colloid, the more bubbles need to be degassed, and the longer the degassing time is required. The degassing speed can be obtained by dividing the mass of the colloid by the degassing time, which is the mass of the colloid that can be degassed per unit time. The negative pressure value is also related to the degassing speed. Within the negative pressure value range that can be set in the degassing chamber, the negative pressure value is inversely proportional to the degassing speed. The chamber negative pressure difference in the first formula of the degassing negative pressure setting model is the minimum negative pressure minus the maximum negative pressure. The chamber negative pressure difference and the minimum negative pressure adjustment value are both negative values. The injection connection flow rate is the colloid that has been degassed in the degassing device and is extracted to supply the injection connection. Speed ​​is the mass of colloid supplied per unit time. Different injection flow rates are selected for colloids of different components. The specific injection flow rate is set according to the specific composition configuration of AB components and has a preset mixing ratio. In the same degassing device, chamber replacement not only needs to consider the degassing time but also the time for releasing the negative pressure and opening and replacing the channel. These times can be reflected in the first formula using the chamber replacement buffer coefficient, which is set according to empirical values. A value between the minimum negative pressure and the maximum negative pressure needs to be found to satisfy the first formula. In order to ensure the life of the degassing chamber and reduce the negative pressure power, a negative pressure value that satisfies the maximum of the first formula is selected. The negative pressure value here is a negative value. The larger the value, the smaller the negative pressure effect corrected in the degassing negative pressure setting value.

[0044] S300, sending the negative pressure value of the degassing device to the current degassing device and setting it.

[0045] It should be noted that a calculation module is externally disposed in the degassing device and is electrically connected to the degassing device control module. After the negative pressure value of the degassing device is calculated, it is sent to the degassing device to set the negative pressure value, so that the subsequent degassing device of the component colloid can most efficiently meet the continuous supply requirements.

[0046] In this embodiment, the degassing speed in the degassing chamber is analyzed to obtain degassing related data, which is substituted into the degassing negative pressure setting model to find the negative pressure value that matches the current colloid degassing speed and injection supply consumption speed. The negative pressure of the degassing device is set so that the degassing speed can keep up with the injection consumption speed, thereby achieving continuous supply of colloid and improving production efficiency.

[0047] The above is a detailed description of the first embodiment of a metering, mixing and degassing control method for liquid silicone provided in the present application. The following is a detailed description of the second embodiment of a metering, mixing and degassing control method for liquid silicone provided in the present application.

[0048] In this embodiment, a method for controlling the metering, mixing and degassing of liquid silicone is further provided. In the aforementioned step S100, the degassing state of the degassing device is specifically identified based on image processing:

[0049] The image inside the degassing chamber is acquired at preset intervals, the image is grayed, and the average gray value in the gray image is calculated; the average gray value is monitored, and when the average gray value is less than the preset gray value threshold, it is determined that the colloid has completed degassing; it should be noted that the degassing chamber is set to be transparent and observable, and image segmentation can be performed after the image is taken, and the area without colloid in the image can be segmented and removed, and the presence of bubbles in the colloid will change the transmittance of the location, the more bubbles, the better the transmittance, the whiter in the image, and the larger the gray value of the pixel in the corresponding gray image; the calculation of the average gray value can reflect the overall bubble presence in the degassing chamber. In this case, the larger the average grayscale value is, the more bubbles there are in the chamber; the preset time of the interval can be set according to the chamber volume and the overall degassing speed; the preset grayscale threshold can be set according to the historical colloid image after degassing. When the average grayscale value is less than the preset grayscale value threshold, it means that there are fewer bubbles in the colloid at this time, and the injection work can be carried out with high quality and reliability; for image processing to identify the degassing state, in addition to judging by the average grayscale value in this embodiment, it can also be identified by identifying the number of bubbles in the image. Due to the flow of the colloid, the internal bubbles will tend to be evenly distributed, and the degassing state is judged according to the number density of bubbles being less than the threshold density.

[0050] Furthermore, the ambient temperature of the degassing device is obtained, and the temperature when the power-on signal is received is recorded. When the difference between the real-time temperature and the temperature at power-on exceeds the temperature threshold, the degassing negative pressure setting value is corrected. It should be noted that the degassing speed is also affected by the temperature. When the temperature changes, the fluidity of the liquid will also change, and the overflow and bursting speed of the bubbles will change accordingly. The environment in which some degassing devices are located cannot maintain a constant temperature, and the room temperature will also change when the working time period of the day changes. Therefore, when the temperature change exceeds the threshold, the temperature change will greatly affect the degassing speed. The degassing negative pressure setting value can be corrected according to the preset proportional coefficient for heating and cooling, or the aforementioned steps S100-S300 can be re-executed to recalculate the degassing negative pressure setting value.
