[0002] In the prior art, for example, a Chinese invention patent with publication number CN116921145A discloses a glass coating device and a coating method thereof, wherein a coating die is used to apply a liquid onto the glass to form a wet film, and then the wet film on the glass is scraped by a scraping die, so that the thickness of the film coated on the glass is relatively uniform, thereby improving the coating effect of the glass coating device. However, the above technical solution still has the following defects: since the contact area between the coating edge of the glass substrate and the outside air is relatively large, the solvent at the edge evaporates faster during heating and drying, and then under the action of surface tension, the solvent in the middle will flow to the edge, and the coating will also gather at the edge, which eventually leads to the defect that the dried coating is thin in the middle and thick at the edge.

A coating module 23 and a drying module 24 are arranged at the top of the shell 1. The coating module 23 includes a first electric push rod 231, a mounting seat 232, a coating head 233, a mounting frame 234, a first spring 235 and a scraper 236.

A mounting frame 234 is vertically arranged on one side of the coating head 233, and the top of the mounting frame 234 is connected to the bottom of the mounting seat 232. A scraper 236 is slidably connected to the mounting frame 234, and the top of the scraper 236 is connected to the mounting seat 232 through the first spring 235. A quality detection mechanism 3 is also arranged on the mounting seat 232. In this embodiment, the two sides of the shell 1 are respectively provided with an automatic loading mechanism and an automatic unloading mechanism, and both the automatic loading mechanism and the automatic unloading mechanism are prior art. The automatic loading mechanism can automatically place the glass substrate to be processed on the workbench 22, and the automatic unloading mechanism can remove the processed glass substrate to realize continuous processing operations. On the one hand, the shell 1 can protect the coating mechanism 2, and on the other hand, it can also reduce the influence of external dust. The moving module 21 can drive the workbench 22 to move so that it can switch between the coating station and the drying station, thereby realizing the coating and drying operations of the glass substrate.The workbench 22 is used to place and fix the glass substrate, wherein an air pump is provided on the base 221, and a suction cup 222 is connected to the air pump, and the suction cup 222 is provided at the top center of the base 221, and is used to adsorb and fix the glass substrate and keep it in a horizontal state. In addition, the adsorption fixation method can avoid damaging the glass substrate, and the use is more convenient and quick; the extension plate 223 and the side baffle plate 225 are both flat plate structures, and the extension plate 223 and the side baffle plate 225 are both arranged vertically, and each extension plate 223 and the side baffle plate 225 are connected to a driver 226 at the bottom, and the driver 226 can drive the extension plate 223 and the side baffle plate 225 to move up and down, thereby forming a groove above the glass substrate, and the depth of the groove is equal to the thickness of the coating Since the coating is prone to be thick at the beginning and thin at the end during the coating process, an extension plate 223 is provided so that the starting and ending positions of the coating are located at two inclined surfaces 224 respectively, and the extension plate 223 is lifted up after the coating is completed, so as to separate the coating at the inclined surface 224 from the coating on the glass substrate to ensure that the coating thickness on the surface of the glass substrate is uniform. At the same time, since the edge of the coating has a large contact area with the air, the solvent in the coating evaporates faster, which leads to the situation that the coating is thicker at the edge and thinner in the middle after drying. Therefore, by providing an extension plate 223 and a side baffle 225, the side edges of the coating can be covered to reduce the solvent volatilization area and speed at the edge, thereby achieving the purpose of eliminating the thick edge. The coating module 23 is used for coating the glass substrate, wherein the first electric push rod 231 is arranged vertically, the first electric push rod 231 is a retractable structure and can drive the mounting seat 232 to move up and down, so that the coating head 233 is close to or away from the top surface of the glass substrate, and the coating head 233 is used to form a coating on the top surface of the glass substrate; the mounting frame 234 is located on the right side of the coating head 233, and the scraper 236 can slide up and down on the mounting frame 234, and can make the bottom end of the scraper 236 close to the top surface of the inclined surface 224 or the side baffle 225 under the pressure of the first spring 235, so that during the movement of the workbench 22, the excess paint on the inclined surface 224 is scraped off and the coating on the glass substrate is flattened, so that the coating surface is flat and uniform. The drying module 24 is located on the right side of the coating module 23, and is used for drying the glass substrate, so that the coating is completely dried and fixed. The quality inspection mechanism 3 is located on the right side of one end of the mounting frame 234 and is arranged obliquely, and is used to detect the flatness of the coating surface, thereby controlling the coating head 233 to change the coating speed, coating thickness, coating width and other parameters accordingly, and can also detect the position of the coating head 233. In addition, a main control box is also provided on the housing 1, and the model of the main control box is preferably MAM-200. The coating module 23 and the drying module 24 are both electrically connected to the main control box to achieve coordinated work.

[0034] Specifically, the mobile module 21 includes an annular slide rail 211, a sliding seat 212, a first motor 213, a first roller 214 and a first belt 215.

The first belt 215 is located inside the annular slide rail 211 , and the first motor 213 can drive the first roller 214 to rotate, thereby driving the first belt 215 to rotate synchronously, so as to drive the sliding seat 212 to slide circumferentially on the annular slide rail 211 , thereby changing the position of the workbench 22 .

[0035] Specifically, the coating module 23 further includes a storage box 237, a feeding hose 238 and an agitator 239. The storage box 237 is arranged on one side of the first electric push rod 231, and the storage box 237 is fixed on the top wall of the housing 1. One end of the feeding hose 238 is connected to the coating head 233, and the other end of the feeding hose 238 is connected to the pump body on the storage box 237.

[0036] Specifically, the quality inspection mechanism 3 includes a detection probe 31 and a main controller 32, both of which are arranged on the mounting seat 232, and the coating head 233 and the detection probe 31 are electrically connected to the main controller 32. In this embodiment, the detection probe 31 is a high-definition camera, which can capture the coating image on the surface of the glass substrate and send the image information to the image recognition module on the main controller 32 for analysis and processing. The image recognition module can identify and extract the characteristic point information of the coating surface, such as bubbles, impurities, etc., and compare it with the defect image pre-stored in the main controller 32, so as to determine whether the coating has defects and the type of defects. If defects exist, the main controller 32 controls the coating head 233 to change the coating speed, coating thickness, coating width and other parameters.

[0037] Specifically, the drying module 24 includes a torsion spring 241, a rotating wheel 242, a transmission belt 243, a slider 244, a second electric push rod 245, a heat insulation cover 246 and a heating wire 247. Two rotating wheels 242 are rotatably connected to the inner top wall of the shell 1, and the two rotating wheels 242 are connected to each other through a transmission belt 243. One end of the torsion spring 241 is connected to the shell 1, and the other end of the torsion spring 241 is connected to the rotating wheel 242. A slider 244 is fixed on the transmission belt 243, and the slider 244 is slidably connected to the inner top wall of the shell 1. The second electric push rod 245 is vertically fixed on the slider 244. The output end of the second electric push rod 245 is connected to the heat insulation cover 246, and the heating wire 247 is arranged in the heat insulation cover 246. In this embodiment, the torsion spring 241 is initially in a relaxed state, and the rotating wheel 242 can twist the torsion spring 241 when it rotates, and then the torsion spring 241 can drive the rotating wheel 242 to restore when the external force is lost. The transmission belt 243 can make the two rotating wheels 242 rotate synchronously, and when the transmission belt 243 rotates, it can drive the slider 244 to slide left and right, so that the heat insulation cover 246 can move a certain distance synchronously with the movement of the workbench 22. The second electric push rod 245 is arranged vertically, and the second electric push rod 245 is a retractable structure and can drive the heat insulation cover 246 to move up and down, so that the heat insulation cover 246 can cover the top of the workbench 22. At this time, the glass substrate is located in the chamber surrounded by the heat insulation cover 246 and the workbench 22 to reduce heat loss and reduce energy consumption. The heating wire 247 can quickly heat the inside of the heat shield 246 to a high temperature to accelerate the volatilization of the solvent in the coating so that the coating dries and sets. A battery for powering the heating wire 247 is also provided outside the heat shield 246 .

[0038] Specifically, an exhaust gas treatment box 248 is further provided at the top of the housing 1, one end of an exhaust pipe 249 is connected to an air suction pump on the exhaust gas treatment box 248, and the other end of the exhaust pipe 249 is connected to the heat insulation cover 246. In this embodiment, an activated carbon adsorption layer is provided in the exhaust gas treatment box 248, and the volatilized solvent will enter the exhaust gas treatment box 248 through the exhaust pipe 249 and be absorbed by the activated carbon adsorption layer to avoid exhaust gas being discharged into the air and causing environmental pollution.

[0039] Specifically, the side surfaces of the extension plate 223 and the side baffle plate 225 are provided with an ultra-slip anti-stick coating. In this embodiment, the ultra-slip anti-stick coating can prevent the paint from adhering to the side walls of the extension plate 223 and the side baffle plate 225, thereby causing damage to the coating edge.

[0040] When in use, first place the glass substrate to be processed on the workbench 22, and fix the glass substrate by suction cup 222, then drive the extension plate 223 and the side baffle 225 upward by driver 226, and make the top surface of the extension plate 223 and the top surface of the side baffle 225 higher than the top surface of the glass substrate by a coating thickness. Then the first motor 213 is started, the first motor 213 drives the first roller 214 to rotate, and the first roller 214 drives the first belt 215 to rotate synchronously, so that the sliding seat 212 slides on the annular slide rail 211. When the sliding seat 212 drives the workbench 22 to move below the coating head 233, the first motor 213 stops working. At this time, the first electric push rod 231 drives the mounting seat 232 to move downward, so that the coating head 233 is just above the inclined surface 224 and the scraper 236 is in contact with the top surface of the extension plate 223. Then the first motor 213 is started again to drive the workbench 22 to move forward at a uniform speed. During the movement of the workbench 22, the coating head 233 will apply a uniform coating on the surface of the glass substrate, and make the uneven thickness parts of the coating at the beginning and end just Located on the inclined surface 224 of the two extension plates 223, during the coating process, when the high-definition camera detects that the coating head 233 moves from above the extension plate 223 at the starting point to above the glass substrate, the extension plate 223 on the right will rise again until the lower end of the inclined surface 224 is flush with the top surface of the coating. At this time, the scraper 236 will scrape off the excess paint on the inclined surface 224 as raw material for filling the depression on the top surface of the coating. Similarly, when the high-definition camera detects that the coating head 233 moves from above the glass substrate at the end point to above the extension plate 223, the extension plate 223 on the left will also rise to the position where the lower end of the inclined surface 224 is flush with the top surface of the coating. At this time, the scraper 236 can scrape off the excess paint on the inclined surface 224 to avoid affecting the next use and reduce raw material waste. After coating is completed, the first electric push rod 231 retracts, and at the same time, the first motor 213 drives the workbench 22 to move to the bottom of the heat insulation cover 246. At this time, the second electric push rod 245 drives the heat insulation cover 246 to move down and abut against the side baffle 225 to form a closed chamber. Then the heating wire 247 is started to heat the inside of the heat insulation cover 246, thereby accelerating the volatilization of the solvent inside the coating, so that the coating dries and sets. The volatilized solvent will enter the exhaust gas treatment box 248 through the exhaust pipe 249 for purification to avoid polluting the environment.

[0043] Step 1: Preparation: prepare the coating equipment and ensure that it is in normal working condition; prepare the coating materials and select appropriate coating materials according to product requirements to ensure their quality and stability;

[0044] Step 2: Set the process parameters, including coating speed, coating thickness and coating width;

[0045] Step 3: Start coating. Place the glass substrate to be coated on the workbench 22 and ensure that the distance and alignment with the coating head 233 are accurate. Then start the coating device and perform coating operation according to the set process parameters and coating requirements.

[0046] Step 4: Quality inspection: monitor the coating quality in real time, use the online inspection system or visual inspection to promptly find problems or defects in the coating process, and adjust the equipment process parameters in time according to the inspection results to ensure that the coating effect meets the requirements. The online inspection system is the quality inspection mechanism 3;

[0047] Step 5: Complete coating. When coating is completed, stop the coating equipment and clean and maintain the equipment, and check the quality of the coated product to ensure that the coating effect meets product requirements.

[0048] Specifically, in step 2, the coating speed is set to determine the coating speed that suits the product requirements; the coating thickness is set to control the coating thickness by setting the pressure of the coating head 233, the nozzle size of the coating head 233 or the coating speed according to the product requirements and the properties of the coating material; the coating width is set to ensure the uniformity and completeness of the coating coverage by setting the width and coating range of the coating head 233 according to the product size and shape.
