It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] like Figures 1 to 4 As shown, the coating and defoaming device disclosed in the first embodiment of the present application includes: a mounting seat assembly 10, a conveying assembly 20 and a film pressing assembly 30, the conveying assembly 20 is arranged on the mounting seat assembly 10, the glass and the coating are arranged on the conveying assembly 20, the film pressing assembly 30 includes a mounting frame structure 31 and a film pressing structure 32, the film pressing structure 32 includes a rotating shaft 321 and an elastic member 322, the rotating shaft 321 is rotatably connected to the mounting frame structure 31, the elastic member 322 is connected to the rotating shaft 321 and is arranged corresponding to the conveying assembly 20, and the cross-sectional area of ​​the elastic member 322 perpendicular to the axis of the rotating shaft 321 gradually increases along the two ends of the elastic member 322 to the middle direction.

[0034] By applying the technical solution of the first embodiment, since the cross-sectional area of ​​the elastic member 322 perpendicular to the axis of the rotating shaft 321 increases continuously from the two ends to the middle direction of the elastic member 322, when the glass and the film body move to the bottom of the film pressing assembly 30 along the conveying assembly 20, the middle part of the first end of the glass first contacts the middle part of the elastic member 322. As the glass continues to be conveyed, the contact area between the elastic member 322 and the glass increases continuously and spreads from the middle to the surroundings, and the bubbles are discharged from both sides of the glass. The technical solution of the first embodiment effectively solves the problem in the prior art that in the process of evacuating bubbles from the glass coating, there is insufficient evacuation of bubbles, resulting in incomplete film bonding.

[0035] like Figure 1 , Figure 3 and Figure 4As shown, in the technical solution of the first embodiment, the projection width of the elastic member 322 in the vertical direction is greater than the projection width of the glass in the vertical direction. The width direction is parallel to the axis extension direction of the rotating shaft 321. Since the projection width of the elastic member 322 in the vertical direction is greater than the projection width of the glass in the vertical direction, during the lamination process, as the glass moves along the conveying assembly 20, the elastic member 322 can completely cover the entire glass, achieving complete lamination and avoiding the problem of the glass edge not being lamination.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, in the technical solution of the first embodiment, the elastic member 322 is made of rubber material. The rubber material has a strong elastic deformation ability and is easily deformed when subjected to force. During the lamination process, it is easy to elastically deform and fit the film body to complete the lamination. After the lamination is completed, the elastic member 322 can be restored to its original state and put into use again; the rubber material is relatively soft and will not scratch the surface of the film body during contact with the film body, thus protecting the film body; the rubber material has a large friction coefficient. During the lamination process, the film body is subjected to the friction force from the elastic member 322, so the film body is not easy to slide, resulting in the problem of misalignment between the film body and the glass.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, in the technical solution of the first embodiment, the outer surface of the elastic member 322 is spherical. During the film pressing process, the glass moves with the conveying assembly 20 to the front of the elastic member 322. Since the outer surface of the elastic member 322 is spherical, the distance between the middle section of the elastic member 322 and the glass is smaller than the distance between the two ends of the elastic member 322 and the glass. As the conveying assembly 20 continues to convey, the middle part of the first end of the glass first contacts the middle section of the elastic member 322, and as the conveying assembly 20 continues to move, the contact position between the glass and the elastic member 322 spreads from the middle to both sides, and the bubbles are pressed from the middle to both sides of the glass by the elastic member 322, and are discharged from the gap between the two sides of the glass and the film body. As the conveying assembly 20 continues to operate, the elastic member 322 rolls along the first end of the glass to the second end, and some bubbles are discharged from the gap between the second end of the glass and the film body. Therefore, during the film pressing process, the elastic part 322 with a spherical outer surface can not only press the bubbles between the film body and the glass from the first end of the glass to the second end of the glass and discharge them, but also press the bubbles between the film body and the glass from the middle of the glass to both sides of the glass and discharge them, thereby achieving a good degassing effect.

[0038] like Figure 1 , Figure 3 and Figure 4As shown, in the technical solution of the first embodiment, the mounting seat assembly 10 includes a mounting groove 11, and the conveying assembly 20 includes a conveying belt 21, and the conveying belt 21 is arranged in the mounting groove 11. The mounting groove 11 is arranged corresponding to the elastic member 322, and the mounting groove 11 guides the conveying belt 21 to prevent the conveying belt 21 from being offset during the movement, causing the glass arranged on the conveying belt 21 to deviate from the position of the elastic member 322, so that the elastic member 322 cannot completely press the glass, and the bubbles between the glass and the film body cannot be completely discharged, resulting in a poor pressing effect.

[0039] like Figures 1 to 4 As shown, in the technical solution of the first embodiment, the height of the upper surface of the conveyor belt 21 in the vertical direction is lower than the height of the upper edge of the mounting groove 11 in the vertical direction. After the glass is placed on the conveyor belt 21, the side wall of the mounting groove 11 limits the glass to prevent the glass from being offset, so that the elastic member 322 cannot completely press the glass, and the bubbles between the glass and the film body cannot be completely discharged, resulting in a poor film pressing effect.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, in the technical solution of the first embodiment, the conveying assembly 20 includes a plurality of conveyor belts 21, and the film pressing structure 32 includes a plurality of elastic members 322, and the plurality of elastic members 322 are arranged one by one corresponding to the plurality of conveyor belts 21. A plurality of groups of conveyor belts 21 are arranged, the plurality of groups of conveyor belts 21 are parallel to each other, the plurality of groups of conveyor belts 21 can share active rollers and driven rollers, the plurality of groups of conveyor belts 21 rotate synchronously, the plurality of groups of conveyor belts 21 are all provided with glass to be film pressed, and the plurality of elastic members 322 respectively press the glass on the correspondingly arranged conveyor belts 21, thereby further improving the working efficiency of the entire device and reducing the film pressing time.

[0041] like Figures 1 to 4 As shown, in the technical solution of the first embodiment, the conveying assembly 20 also includes a suction cup 22, the suction cup 22 is connected to the conveyor belt 21, and the glass is set on the suction cup 22. The suction cup 22 includes a connecting portion and an elastic portion, the connecting portion is connected to the conveyor belt 21, and the elastic portion is connected to the connecting portion. In the process of placing the glass, the glass is aligned with the elastic portion, and downward pressure is applied to the glass. The upper edge of the elastic portion contacts the glass, and the air between the elastic portion and the glass is discharged, and a negative pressure environment is generated between the two. The glass is adsorbed on the elastic portion to complete the fixation of the glass. The suction cup 22 performs negative pressure adsorption on the glass, so that the glass is fixed on the conveying assembly 20 to prevent the position of the glass from moving.

[0042] like Figure 5As shown, the difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that the mounting frame structure 31 includes a first mounting frame 311 and a second mounting frame 312, the first mounting frame 311 is connected to the mounting seat assembly 10, the second mounting frame 312 is movably connected to the first mounting frame 311, and the film pressing structure 32 is rotatably connected to the second mounting frame 312. The second mounting frame 312 is movably connected to the first mounting frame 311, so the film pressing structure 32 connected to the second mounting frame 312 moves with the second mounting frame 312, and the distance between the film pressing structure 32 and the conveying assembly 20 changes with the movement of the film pressing structure 32. The above structure makes the entire film degassing device applicable to degassing of glass of different thicknesses, and has stronger versatility.

[0043] like Figure 5 As shown, in the technical solution of the second embodiment, the second mounting frame 312 includes a long hole, and a fastener is inserted between the long hole and the first mounting frame 311. After loosening the fastener and adjusting the second mounting frame 312, the film pressing structure 32 is located at a suitable height, and then the fastener is tightened to fix the position of the second mounting frame 312, and the film pressing structure 32 is used to press the film on the glass. The method of adjusting the position of the second mounting frame 312 by cooperating with the long hole and the fastener is simple to process, easy to operate, convenient to disassemble, and easy to maintain. The first mounting frame 311 is provided with a U-shaped groove, and the U-shaped groove is correspondingly arranged with the rotating shaft 321. The projection of the rotating shaft 321 in the vertical direction is located within the projection of the U-shaped groove in the vertical direction. The setting of the U-shaped groove avoids interference between the rotating shaft 321 and the first mounting frame 311 during the process of adjusting the height of the second mounting frame 312 in the vertical direction.

[0044] The difference between the technical solution of the third embodiment and the technical solution of the first embodiment is that the outer surface of the elastic member 322 is an ellipsoid. The major axis of the ellipsoid is located on the same straight line as the rotation axis 321. When the width is the same, the difference between the distance between the two ends of the elastic member 322 and the glass and the distance between the middle section and the glass in the technical solution of the third embodiment is smaller than the difference between the distance between the two ends of the elastic member 322 and the glass and the distance between the middle section and the glass in the technical solution of the first embodiment. Therefore, the elastic member 322 in the technical solution of the third embodiment is easier to completely fit the glass, and the lamination effect is better when the glass width is larger.

[0045] From the above, it can be known that the product is placed on the track (conveyor belt 21), and the vacuum suction cup (suction cup 22) below will absorb the product, and move it to the rubber ball roller (elastic part 322) through the track. The ball (elastic part 322) is round, and the first contact is the highest position of the circle (elastic part 322), and then the contact area gradually increases. This solution is used to solve the problem of bubbles in the release film and the product. After the cover plate bonding process, it is necessary to measure the ASF film bonding size through the second element to see if it is offset. The release film needs to be torn off to measure the size. After the measurement is completed, the release film needs to be pasted back to the product, but a large number of bubbles will appear. This application uses a rubber ball roller (elastic part 322) to press the bubbles out from the inside to the outside to solve this problem; three tracks (installation slot 11) are designed to increase efficiency; the ball roller (elastic part 322) is detachable and replaced regularly to prevent other defects caused by aging.
