Description

Technical Field

[0001] The present invention relates to the field of glass manufacturing, and in particular to a spin coating method, system and intelligent terminal. Background Art

[0002] A spin coater is a device that drives the glass to rotate and evenly applies glue between the glass and the spacer strips.

[0003] In the prior art, insulating glass is generally composed of spacers and glass. The spacers are used to separate the glass so that a closed air layer is formed between the two pieces of glass. When manufacturing insulating glass, the spacers are generally placed between the glass first, and then the glass is driven to rotate at a constant speed by a rotary coating machine, and glue is evenly injected between the glass and the spacers through the injection nozzle on the rotary coating machine to form a sealing line.

[0004] When the shapes of the glass and the spacer are different, the rotary coating machine drives the glass to rotate at a fixed speed, which can easily cause the injection nozzle to move at different speeds on the glass, resulting in different amounts of glue at different positions on the glass, and thus uneven sealing lines. Summary of the Invention

[0005] In order to improve the convenience of sealing insulating glass and reduce the uneven sealing, the present invention provides a rotary coating method, system and intelligent terminal.

[0006] In a first aspect, the present invention provides a spin coating method, which adopts the following technical solution:

[0007] A spin coating method comprising:

[0008] Collect processing images of processing stations;

[0009] identifying a glass image and a rotation center from the processed image, and identifying a glass outline from the glass image;

[0010] determining a circumscribed radius in response to the glass contour and the rotation center, determining a maximum rotational speed in response to the circumscribed radius, determining a contour distance based on the rotation center and the glass contour, and finally generating a rotational speed curve in response to the contour distance, the circumscribed radius, and the maximum rotational speed;

[0011] The preset rotating device is controlled to rotate according to the rotation speed curve so that the glass is evenly injected with glue.

[0012] By adopting the above technical solution, the speed at which the rotary coater drives the glass to rotate is adjusted according to the distance between the edge of the glass and the rotation center of the rotary coater, so that the injection nozzle can inject at a uniform speed on the glass, thereby reducing uneven sealing and improving the convenience of sealing the insulating glass.

[0013] Optionally, also include:

[0014] determining a speed deviation in response to the speed profile;

[0015] When the rotational speed deviation is greater than a preset deviation threshold, determining a differential curve based on the rotational speed curve;

[0016] determining a correction curve in response to the difference curve;

[0017] The speed profile is modified in response to the correction profile.

[0018] By adopting the above technical solution, when the glass rotates, the injection nozzle needs to adjust its position to track the shape of the glass edge. When the shape of the glass edge is more complex, it is easy for the injection nozzle to have difficulty tracking the shape of the glass edge, resulting in inadequate glue injection. By checking the change in the speed at which the rotary glue coater drives the glass to rotate, the change in the shape of the glass edge can be judged, and the speed of glass rotation can be corrected according to the change in shape.

[0019] Optionally, a spacer bar inspection method is further included, and the spacer bar inspection method includes:

[0020] Before controlling the preset rotating device to rotate according to the rotation speed curve, determining the spacing area of ​​the spacer bars from the glass image, and determining the installation area of ​​the spacer bars based on the glass contour;

[0021] generating a mounting deviation in response to the spacing area and the mounting area, and determining a deviation position based on the mounting deviation;

[0022] controlling a preset vibration device to move to a deviation position, and determining a vibration frequency in response to the installation deviation;

[0023] Controlling a preset vibration device to vibrate according to the vibration frequency;

[0024] When the installation deviation is greater than a preset upper limit of the offset, generating a movement stroke in response to the deviation position and the installation deviation;

[0025] The preset moving device is controlled to press the preset spacer bar according to the moving stroke to adjust the position of the spacer bar.

[0026] By adopting the above technical solution, the spacer is used to separate the two pieces of glass and keep the air layer between the two pieces of glass isolated from the outside world. When the spacer is offset, it is easy to cause the separation and sealing functions of the spacer to be reduced. The deviation between the position of the spacer in the image and the predetermined position is compared in real time, so that when the spacer deviates outward, the position of the spacer is adjusted by cooperating with the vibration device and the moving device.

[0027] Optionally, the spacer inspection method further includes:

[0028] When the installation deviation is greater than a preset upper limit of the deviation, determining a tilting position in response to the deviation position;

[0029] determining whether the tilted position is tilted from the glass image;

[0030] When the tilted position is tilted, a fixed stroke is generated in response to the moving stroke;

[0031] At the same time, the preset moving device is controlled to press the preset spacer bars according to the moving stroke and the fixed stroke respectively.

[0032] By adopting the above technical solution, when one end of the spacer bar that is offset outward is pressed by a mobile device, the other end of the spacer bar away from the end that is offset outward is easily offset synchronously, and the position of the other end of the spacer bar is detected in real time, so that when the other end of the spacer bar is offset, the two ends of the spacer bar are pressed synchronously by the mobile device to reduce the offset of the spacer bar.

[0033] Optionally, the spacer inspection method further includes:

[0034] When the installation deviation is less than a preset lower limit of deviation, determining the leakage location based on the deviation position and the installation area;

[0035] controlling a preset inflation device to move to a leakage position, and determining a deviation extreme value in response to the installation deviation and the leakage position;

[0036] determining a driving time in response to the extreme deviation value, and identifying a glass weight from the glass image;

[0037] determining a driving pressure in response to the glass weight;

[0038] The preset inflation device is controlled to inflate air into the air layer of the insulating glass according to the driving time and driving pressure to drive the spacer to move.

[0039] By adopting the above technical solution, when the spacer bar deviates into the air layer between the glass panes, the inflation device is controlled to ventilate into the air layer between the glass panes through the gap created by the displacement of the spacer bar, thereby increasing the air pressure in the air layer and discharging it outward through the gap to drive the spacer bar to move outward synchronously.

[0040] Optionally, the spacer inspection method further includes:

[0041] When the installation deviation is less than a preset lower limit of the offset, determining a moving rate based on the spacing area;

[0042] generating a lubrication area in response to the spacing area and the mounting area when the movement rate is lower than a preset adjustment threshold;

[0043] generating a lubrication stroke in response to the lubrication area;

[0044] A preset oil injection device is controlled to inject oil in the lubrication area according to the lubrication stroke.

[0045] By adopting the above technical solution, when the friction between the spacer bar and the glass is large, it is easy for the airflow overflowing from the air layer to make it difficult to drive the spacer bar to move outward. At this time, oil is sprayed on the outward moving path of the spacer bar through the oil spraying device to reduce the friction of the spacer bar, thereby driving the spacer bar to move outward.

[0046] Optionally, a glue injection control method is further included, and the glue injection control method includes:

[0047] determining a glue injection position in response to the glass image;

[0048] Controlling a preset injection nozzle to move to the glue injection position to inject glue, and determining the glue injection thickness based on the glue injection position;

[0049] When the glue injection thickness is greater than a preset front engraving thickness, determining a cooling position in response to the front engraving thickness and the glue injection position;

[0050] The preset roller device is controlled to move to the cooling position and roll along with the rotation of the glass, and the injection thickness is defined as the pre-engraving thickness.

[0051] By adopting the above technical solution, a roller device is used to roll on the outside of the glass, thereby lowering the temperature of the glass surface, and then lowering the temperature of the glue between the glass and the glass, thereby accelerating the solidification speed of the glue and reducing the flow of glue to cause gaps between the glue and the glass or between the glue and the spacer.

[0052] Optionally, the glue injection control method further includes:

[0053] When the glue injection thickness is greater than the preset pre-engraved thickness, collecting the device temperature of the roller device;

[0054] When the device temperature is greater than a preset temperature drop threshold, determining a pressing force in response to the device temperature;

[0055] determining a cooling temperature differential in response to the device temperature and a cooling threshold, and determining a hysteresis distance in response to the cooling temperature differential;

[0056] The cooling position is corrected in response to the hysteresis distance, and a preset roller device is controlled to press the cooling position according to the pressing force.

[0057] By adopting the above technical solution, when the glue cools down too slowly, bubbles are likely to appear in the glue. The roller device presses against the glass to vibrate the glass, thereby causing the bubbles in the glue to emerge, thereby reducing the situation where bubbles in the glue cause poor sealing effect.

[0058] In a second aspect, the present application provides a spin coating system, which adopts the following technical solution:

[0059] A spin coating system comprising:

[0060] An acquisition module, used to collect processing images and device temperature;

[0061] A memory for storing any of the above-mentioned spin coating methods;

[0062] The processor can load and execute the program in the memory.

[0063] In a third aspect, the present application provides a smart terminal that adopts the following technical solution:

[0064] An intelligent terminal comprises a memory and a processor, wherein the memory stores a program that can be loaded and executed by the processor and any one of the above-mentioned spin-coating methods.

[0065] By adopting the above technical solution, the speed at which the rotary coater drives the glass to rotate is adjusted according to the distance between the edge of the glass and the rotation center of the rotary coater, so that the injection nozzle can inject at a uniform speed on the glass, thereby reducing uneven sealing and improving the convenience of sealing the insulating glass.

[0066] In summary, this application includes at least one of the following beneficial technical effects:

[0067] 1. Adjust the speed of the rotary glue coater to drive the glass to rotate according to the distance between the edge of the glass and the rotation center of the rotary glue coater, so that the injection nozzle can inject at a uniform speed on the glass, thereby reducing the uneven sealing and improving the convenience of sealing the insulating glass;

[0068] 2. When the glass rotates, the injection nozzle needs to adjust its position to track the shape of the glass edge. When the shape of the glass edge is complex, it is easy for the injection nozzle to have difficulty tracking the shape of the glass edge, resulting in inadequate injection of glue. By checking the change in the speed at which the rotary glue coater drives the glass to rotate, the change in the shape of the glass edge can be determined, and the glass rotation speed can be adjusted according to the change in shape.

[0069] 3. The spacer is used to separate the two pieces of glass and keep the air layer between the two pieces of glass isolated from the outside world. When the spacer is offset, it is easy to reduce the separation and sealing function of the spacer. The deviation between the position of the spacer in the image and the predetermined position is compared in real time, so that when the spacer deviates outward, the position of the spacer is adjusted by cooperating with the vibration device and the moving device.

[0078] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0079] Reference Figure 1 , a spin coating method comprising:

[0080] Step 100: Acquire processing images of the processing station.

[0081] The processing station refers to the area on the rotary coating machine used for processing glass. The processing image refers to a picture of the processing station. The processing image can be obtained through a camera fixed on the rotary coating machine. The method for obtaining the processing image and the processing station are selected by the staff according to actual conditions and will not be elaborated here.

[0082] Step 101: Identify a glass image and a rotation center from the processed image, and identify a glass outline from the glass image.

[0083] The glass image refers to the picture of the glass in the processed image. The image recognition technology can be used to cut out the part of the picture containing the glass from the processed image as the glass image. The rotation center refers to the center point when the rotary coater drives the glass to rotate. Generally, the position of the camera fixed on the rotary coater is adjusted to make the center point of the processed image coincide with the rotation center, and when the glass is placed on the rotary coater, the center point of the glass coincides with the rotation center. The rotation center can be identified from the processed image through image recognition technology. The method of identifying the glass image and the rotation center is common knowledge among people in this field and will not be elaborated here.

[0084] The glass contour refers to the contour position of the glass, and the glass contour can be identified from the glass image through image recognition technology. The method of identifying the glass contour is common knowledge in this field and will not be described in detail here.

[0085] Step 102: Determine a circumscribed radius in response to the glass contour and the rotation center, determine a maximum rotation speed in response to the circumscribed radius, determine a contour distance based on the rotation center and the glass contour, and finally generate a rotation speed curve in response to the contour distance, circumscribed radius and maximum rotation speed.

[0086] The circumscribed radius refers to the radius of the smallest circumscribed circle on the glass with the rotation center as the center, that is, the farthest distance from the rotation center on the glass contour. The method for determining the circumscribed radius is common knowledge among people in this field and will not be elaborated here.

[0087] The maximum speed refers to the maximum angular velocity of the rotary gluing table. The thickness of the sealing line required for different sizes of glass is different. In order to ensure a stable connection and seal between the glass and the spacer, it is necessary to ensure that the injection nozzle stays on the edge of the glass for a sufficient time to form a sealing line of sufficient thickness. The maximum speed is the maximum angular velocity when sufficient glue is evenly injected on the edge of the glass with an external radius. The maximum speed can be obtained from the speed data table, which refers to a data table that records different external radii and their corresponding maximum speeds; among them, the rotary gluing machine refers to a device used to drive the insulating glass to rotate so as to apply glue to the edge of the insulating glass, and the rotary gluing table is a platform on the rotary gluing machine for carrying the insulating glass, that is, the motor in the rotary gluing machine drives the rotary gluing table, thereby driving the insulating glass placed on the rotary gluing table to rotate synchronously with the rotary gluing table.

[0088] Among them, the injection nozzle refers to the equipment on the rotary coating machine used to inject glue onto the glass. The injection nozzle is selected by the staff according to the actual situation and will not be described in detail here.

[0089] The contour distance refers to the distance between each point on the glass contour and the rotation center. The method for determining the contour distance is common knowledge to those skilled in the art and will not be elaborated here.

[0090] The speed curve refers to the angular velocity change curve of the glass driven by the rotary glue injection machine. The farther the edge position on the glass is from the rotation center, the faster the movement speed. In order to ensure the uniformity of the sealing line, the injection nozzle should stay at the same speed at each edge of the glass, that is, the movement speed of the edge position should be consistent. The required movement speed of each point on the glass contour can be calculated according to the formula (circumscribed radius / contour distance) = (maximum speed / moving speed), and then the movement speeds are arranged in the time sequence of the glass contour passing the injection nozzle to obtain the speed curve.

[0091] Step 103: Control the preset rotating device to rotate according to the rotation speed curve so that the glass is evenly injected with glue.

[0092] The rotating device refers to the equipment on the rotary coating machine used to drive the glass to rotate. The rotating device is selected by the staff according to the actual situation and will not be described in detail here.

[0093] Adjust the speed of the rotary glue coater driving the glass to rotate according to the distance between the glass edge and the rotation center of the rotary glue coater, so that the injection nozzle can inject at a uniform speed on the glass, thereby reducing uneven sealing and improving the convenience of sealing the insulating glass.

[0094] Reference Figure 2 , a spin coating method, further comprising:

[0095] Step 104 : Determine a speed deviation in response to the speed curve.

[0096] The speed deviation refers to the difference between the maximum speed and the minimum speed on the speed curve. The method for determining the speed deviation is common knowledge in this field and will not be elaborated here.

[0097] Step 105: When the rotation speed deviation is greater than a preset deviation threshold, a differential curve is determined based on the rotation speed curve.

[0098] The deviation threshold refers to the maximum speed deviation that the injection nozzle can track in a timely manner. The deviation threshold is selected by the staff based on actual conditions and is not detailed here. A speed deviation greater than the deviation threshold indicates that the speed value of the speed curve has changed significantly. The speed value changes with the profile distance, that is, the profile distance changes too much, which can easily make it difficult for the injection nozzle to track the glass edge in a timely manner. The differential curve is a curve calculated by taking the speed curve and performing a time-series difference calculation. The differential curve shows the degree of change in the profile distance at each time period.

[0099] Step 106: Determine a correction curve in response to the difference curve.

[0100] The correction curve refers to a curve used to correct the rotational speed of a rotating device. The higher the absolute value of the value in the differential curve, the greater the degree of change in the profile distance, and the greater the speed that the rotating device needs to reduce. The absolute value of the differential value can be read from the differential curve in chronological order, and then the corresponding correction value can be queried from the correction relationship table according to the absolute value, and the correction value is arranged in chronological order to form a correction curve. The correction relationship table refers to a data table that records different differential values ​​and their corresponding correction values.

[0101] Step 107 : Correcting the rotation speed curve in response to the correction curve.

[0102] When the glass rotates, the injection nozzle needs to adjust its position to track the shape of the glass edge. When the shape of the glass edge is more complex, it is easy for the injection nozzle to have difficulty tracking the shape of the glass edge, resulting in inadequate glue injection. By checking the change in the speed at which the rotary glue coater drives the glass to rotate, the change in the shape of the glass edge can be judged, and the speed of glass rotation can be corrected according to the change in shape.

[0103] Reference Figure 3 , the spacer inspection methods include:

[0104] Step 200 : Before controlling the preset rotating device to rotate according to the rotation speed curve, determining the spacing area of ​​the spacer bars from the glass image, and determining the installation area of ​​the spacer bars based on the glass contour.

[0105] The spacing area refers to the contour position information of the spacing bar, and the spacing area can be identified from the glass image through image recognition technology. The identification method of the spacing area is common knowledge in this field and will not be described here.

[0106] The installation area refers to the position information of the spacer strips to be installed on the glass. The spacer strips are generally installed along the edge of the glass. The installation area is the outline position information of the spacer strips after the spacer strips are installed on the edge of the glass. The installation area can be determined by image recognition technology. The method for determining the installation area is common knowledge among people in this field and will not be elaborated here.

[0107] Step 201: Generate an installation deviation in response to the spacing area and the installation area, and determine a deviation position based on the installation deviation.

[0108] Installation deviation refers to the maximum distance between the spacing area and the installation area. Generally, the distances between the two ends of the spacing area and the two ends of the installation area are calculated separately, and the larger one is selected as the installation deviation. Generally, the direction of deviation into the air layer between the glass is defined as a negative sign, and the direction of deviation toward the outside is defined as a positive sign. The method for determining the installation deviation is common knowledge among people in this field and will not be elaborated here.

[0109] The deviation position refers to the position information on the spacing area corresponding to the installation deviation, that is, the position of the end of the spacing area with the largest deviation from the installation area. The method for determining the deviation position is common knowledge among people in this field and will not be elaborated here.

[0110] Step 202: Control a preset vibration device to move to a deviation position, and determine a vibration frequency in response to the installation deviation.

[0111] A vibration device is a device used to vibrate the glass. The device is selected by the operator based on the specific situation and is not described here. The vibration frequency refers to the frequency at which the device causes the glass to vibrate. This vibration facilitates adjustment of the spacer position, and the higher the vibration frequency, the easier it is to move the spacer. The vibration frequency can be obtained from a vibration data sheet, which records different installation deviations and their corresponding vibration frequencies.

[0112] Step 203: Control the preset vibration device to vibrate according to the vibration frequency.

[0113] When the glass and the spacer are placed on the rotary coating machine, the friction between the spacer and the glass is large, making it difficult for the glass and the spacer to move relative to each other. At this time, the friction between the spacer and the glass is reduced by the vibration device to facilitate the adjustment of the position of the spacer.

[0114] Step 204: When the installation deviation is greater than a preset upper limit of the offset, a movement stroke is generated in response to the deviation position and the installation deviation.

[0115] The maximum offset limit is the maximum allowable offset of the spacer bar. This limit is determined by the operator based on actual conditions and is not detailed here. Installation deviations greater than the maximum offset limit indicate excessive outward offset of the spacer bar, which can reduce its sealing effectiveness against the air gap.

[0116] The moving device is a device used to press the spacer bar to drive it into the air layer. The moving device is selected by the operator based on actual conditions and is not described in detail here. The moving stroke is the path that the moving device takes to press the deviation position into the air layer by the installation deviation distance. The method for generating the moving stroke is common knowledge in the art and is not described in detail here.

[0117] Step 205: Control the preset moving device to press the preset spacer according to the moving stroke to adjust the position of the spacer.

[0118] The spacer is used to separate two pieces of glass and keep the air layer between the two pieces of glass isolated from the outside world. When the spacer is offset, it is easy to reduce the separation and sealing functions of the spacer. The deviation between the position of the spacer in the image and the predetermined position is compared in real time, so that when the spacer deviates outward, the position of the spacer is adjusted by cooperating with the vibration device and the moving device.

[0119] Reference Figure 4 , the spacer inspection method also includes:

[0120] Step 206 : When the installation deviation is greater than a preset upper limit of the offset, determining a tilting position in response to the deviation position.

[0121] The warping position refers to the position information of the end of the spacer bar away from the deviation position. The method for determining the warping position is common knowledge in this field and will not be described in detail here.

[0122] Step 207: Determine from the glass image whether the tilted position is tilted.

[0123] Warping refers to the situation where the spacer bar deviates toward the outside. Image recognition technology can be used to determine whether the warping position has warped. The method for determining warping is common knowledge among people in this field and will not be described in detail here.

[0124] Step 208: When the tilted position is tilted, generating a fixed stroke in response to the moving stroke.

[0125] The tilting of the tilted position means that there is at least one point between the tilted position and the deviation position where the friction between the spacer and the glass is relatively large. At this time, the tilted position needs to be fixed to reduce the tilting of the tilted position when the deviation position is pressed. The fixed stroke is the path for the mobile device to press the tilted position to reduce the tilting of the tilted position. The fixed stroke should reduce the interference with the moving stroke. The production method of the fixed stroke is common knowledge among people in this field and will not be elaborated here.

[0126] Step 209: Simultaneously controlling the preset moving device to press the preset spacer bars according to the moving stroke and the fixed stroke.

[0127] When one end of the spacer bar that is offset outward is pressed by a mobile device, the other end of the spacer bar away from the end that is offset outward is likely to be offset synchronously. The position of the other end of the spacer bar is detected in real time, so that when the other end of the spacer bar is offset, the two ends of the spacer bar are pressed synchronously by the mobile device to reduce the offset of the spacer bar.

[0128] Reference Figure 5 , the spacer inspection method also includes:

[0129] Step 210: When the installation deviation is less than a preset lower limit of the offset, determine the leakage position based on the deviation position and the installation area.

[0130] The lower limit of offset refers to the maximum allowable offset of the spacer into the air layer. This lower limit is selected by the operator based on actual conditions and is not detailed here. An installation deviation less than the lower limit indicates that the spacer is excessively offset into the air layer, which can reduce the sealing effect of the spacer on the air layer. The leakage location refers to the point in the air layer where the air tightness is lowest after the spacer is offset. The midpoint between the deviation location and the point in the installation area corresponding to the deviation location is generally used as the leakage location. The method for determining the leakage location is common knowledge in this field and is not detailed here.

[0131] Step 211: Control the preset inflation device to move to the leakage position, and determine the deviation extreme value in response to the installation deviation and the leakage position.

[0132] The deviation extreme value refers to the installation deviation corresponding to the leakage position. The method for determining the deviation extreme value is common knowledge among those skilled in the art and will not be elaborated here.

[0133] Step 212: Determine the driving time in response to the extreme deviation value, and identify the glass weight from the glass image.

[0134] The inflation device refers to a device used to inflate the air layer to increase the air pressure value in the air layer. The inflation device can adopt an air pump. The inflation device is selected by the staff according to the actual situation and will not be described in detail here.

[0135] The driving time refers to the time required for the inflation device to move the spacer bar to the deviation extreme value at a predetermined slip speed, that is, the quotient of the deviation extreme value and the slip speed is taken as the driving time, where the slip speed refers to the pre-set speed value for adjusting the position of the spacer bar. The slip speed is selected by the staff according to the actual situation and will not be elaborated here.

[0136] Glass weight refers to the weight of a single layer of glass constituting insulating glass. Glass weight can be determined by image recognition technology. The method for identifying glass weight is common knowledge in this field and will not be elaborated here.

[0137] Step 213: Determine the driving pressure in response to the glass weight.

[0138] The driving pressure refers to the air pressure required to drive the spacer to move at the sliding speed. The driving pressure can be obtained from the pressure relationship table. The pressure relationship table refers to a data table that records different glass masses and their corresponding driving pressures.

[0139] Step 214: Control the preset inflation device to inflate the air layer of the insulating glass according to the driving time and driving pressure to drive the spacer to move.

[0140] First, the outward-deflected spacer is pressed into place by the moving device, and then it is detected whether there is a spacer deflected into the air layer. When the spacer deflects into the air layer between the glass panes, the inflation device is controlled to ventilate the air layer between the glass panes through the gap created by the deflection of the spacer, thereby increasing the air pressure in the air layer and discharging it outward through the gap to drive the spacer to move outward synchronously.

[0141] Reference Figure 6 , the spacer inspection method also includes:

[0142] Step 215: When the installation deviation is less than a preset lower limit of the offset, determining a moving speed based on the interval area.

[0143] The moving rate refers to the speed at which the spacer moves, which can be obtained by identifying the spacer area in the glass image using image recognition technology. The method for identifying the moving rate is common knowledge among those skilled in the art and will not be elaborated here.

[0144] Step 216 : When the movement rate is lower than a preset adjustment threshold, generating a lubrication area in response to the spacing area and the installation area.

[0145] The adjustment threshold refers to the minimum speed at which the spacer bar must move. This threshold is selected by the operator based on actual conditions and is not detailed here. A speed below the adjustment threshold indicates that the spacer bar is moving too slowly, meaning that the friction between the spacer bar and the glass is too great. In this case, the friction between the spacer bar and the glass needs to be reduced to facilitate movement. The lubrication area refers to the area on the glass that requires lubrication, namely, the gap between the spacer area and the mounting area. Determining the lubrication area is common knowledge in the art and is not detailed here.

[0146] Step 217 : Generate a lubrication stroke in response to the lubrication area.

[0147] The oil spray device is a device used to spray oil onto the glass. The oil spray device is selected by the operator based on actual conditions and is not described in detail here. The lubrication stroke refers to the path of oil sprayed on the lubrication area by the oil spray device. The method for generating the lubrication stroke is common knowledge in the art and is not described in detail here.

[0148] Step 218: Control the preset oil injection device to inject oil in the lubrication area according to the lubrication stroke.

[0149] When the friction between the spacer and the glass is large, it is easy for the airflow overflowing from the air layer to make it difficult to drive the spacer to move outward. At this time, oil is sprayed on the outward moving path of the spacer through the oil spraying device to reduce the friction of the spacer, thereby driving the spacer to move outward.

[0150] Reference Figure 7 , injection control methods include:

[0151] Step 300: Determine a glue injection position in response to the glass image.

[0152] The injection position refers to the position on the glass waiting for injection, that is, the intersection of the line connecting the rotation center and the injection nozzle and the glass outline. The method for determining the injection position is common knowledge among people in this field and will not be elaborated here.

[0153] Step 301: Control a preset injection nozzle to move to the glue injection position to inject glue, and determine the glue injection thickness based on the glue injection position.

[0154] The injection thickness refers to the thickness of the glue at the injection position, which can be obtained by identifying the glass image using image recognition technology. The identification method of the injection thickness is common knowledge among people in this field and will not be elaborated here.

[0155] Step 302: When the glue injection thickness is greater than a preset front engraving thickness, a cooling position is determined in response to the front engraving thickness and the glue injection position.

[0156] The roller device refers to a device that rolls on the glass surface to cool the glass surface. The roller device is fixed on the rotary coating machine. When the glass rotates, the friction between the glass and the roller drives the roller to rotate. The surface of the roller device is equipped with a track. When the roller device rolls on the glass surface, it can drive the glass to vibrate. The roller device is selected by the staff according to the actual situation and will not be described in detail here.

[0157] The pre-engraved thickness refers to the glue thickness after the previous round of glue injection, and the pre-engraved thickness is initially 0. When the injected glue thickness is greater than the pre-engraved thickness, it indicates the start of a new round of glue injection. The cooling position refers to the position where the roller device rolls on the glass surface, that is, the position where the glue is reflected on the glass surface. The method for determining the cooling position is common knowledge in the art and will not be elaborated here.

[0158] Step 303: Control a preset roller device to move to the cooling position and roll along with the rotation of the glass, and define the injection thickness as the pre-engraving thickness.

[0159] A roller device is used to roll on the outside of the glass to reduce the temperature of the glass surface, thereby reducing the temperature of the glue between the glass and the glass, thereby accelerating the solidification of the glue and reducing the flow of glue to cause gaps between the glue and the glass or between the glue and the spacer.

[0160] Reference Figure 8 , the glue injection control method also includes:

[0161] Step 304: When the injection thickness is greater than the preset pre-engraved thickness, the device temperature of the roller device is collected.

[0162] The device temperature refers to the temperature value of the roller surface. The device temperature can be collected by a temperature sensor fixed in the roller. The method of collecting the device temperature is selected by the staff according to the actual situation and will not be described in detail here.

[0163] Step 305: When the device temperature is greater than a preset temperature drop threshold, determine the pressure intensity in response to the device temperature.

[0164] The cooling threshold refers to the maximum temperature at which the roller assembly can effectively reduce the glass surface temperature. This threshold is selected by staff based on actual circumstances and is not detailed here. If the device temperature exceeds the cooling threshold, the roller assembly is too hot, making it difficult for the glue to solidify quickly and potentially leading to bubbles. The pressure intensity refers to the force with which the roller assembly presses against the glass surface, causing the glass to vibrate as the roller rolls across it. The pressure intensity can be found in the pressure relationship table, which records different device temperatures and their corresponding pressure intensities.

[0165] Step 306: Determine a cooling temperature difference in response to the device temperature and a cooling threshold, and determine a hysteresis distance in response to the cooling temperature difference.

[0166] The cooling temperature difference refers to the difference between the device temperature and the cooling threshold. The cooling temperature difference shows the high temperature condition of the roller.

[0167] The lag distance refers to the distance between the roller and the latest injected glue. When the roller is overheated, the glue is difficult to cool and solidify in time, and the roller needs to continue rolling to cool the glue. The lag distance is the distance between the dividing line between completely solidified glue and incompletely solidified glue and the latest injected glue. The lag distance can be obtained from the lag relationship table. The lag relationship table refers to a data table that records different cooling temperature differences and their corresponding lag distances.

[0168] Step 307: Correcting the cooling position in response to the hysteresis distance, and controlling a preset roller device to press the cooling position according to the pressing force.

[0169] Generally, the original cooling position is moved a lag distance toward the rotation center as the new cooling position.

[0170] When the glue cools down too slowly, bubbles are likely to form in the glue. The roller device is used to press against the glass to vibrate the glass, thereby causing the bubbles in the glue to emerge, thereby reducing the situation where bubbles in the glue cause poor sealing effect.
