Description

Technical Field

[0001] The invention relates to glass manufacturing technology, in particular to a post-coating edge sealing device suitable for diffuse reflection colored glass acid etching process. Background Art

[0002] Patent CN114394760A discloses a method for preparing diffuse reflective colored glass, which uses magnetron sputtering coating combined with acid etching process to produce colored glass with a multi-angle uniform color visual effect. At present, after continuous practice, this preparation method is gradually being promoted.

[0003] In the magnetron sputtering coating combined with acid etching process provided by this patent, in order to ensure that the glass has a uniform haze value, when etching on one side, the other side needs to be encapsulated for acid resistance to prevent acid etching. There are the following means of acid-resistant encapsulation: one is to use jig encapsulation, which is mostly used for small-sized glass such as touch screens; the other is to use film to prevent acid, which is commonly used in the acid etching and frosting process of large-sized original glass in the existing architectural decoration industry. Considering the purpose and size of diffusely reflected colored glass, the use of film to prevent acid is the most reasonable solution.

[0004] Conventional acid-proof coatings usually have a coating area slightly smaller than the glass plate size. However, diffuse colored glass uses immersion acid etching. If the coating area is smaller than the glass plate area, once the uncoated area is acid-etched, the final atomized color of the glass will show a more obvious visual difference. Therefore, the size of the acid-proof coating of diffuse colored glass should not be smaller than the glass plate area.

[0005] In the prior art, since the coating equipment cannot accurately cut along the edge of the glass plate when cutting the film, the acid-proof coating of the diffuse reflective colored glass adopts a strategy in which the coating size is slightly larger than the glass plate. When the coating size is larger than the area of ​​the glass plate, during immersion acid etching, the acid-proof film warped at the edge of the glass plate is not attached to the side of the glass, and there is a risk that the acid-proof film will be detached from the surface of the glass plate under liquid surface disturbance; at the same time, the uniformity of the coating of a large area of ​​glass plate is difficult to control, and there is a problem of acid penetrating into the protective surface after long-term immersion, resulting in uneven color of the same piece of glass and defective products. At present, in order to avoid the above problems, the warped coating is manually pressed onto the side of the glass plate, which is inefficient and has high labor costs. Summary of the invention

[0006] In response to the problems raised in the background technology, the purpose of the present invention is to provide a post-lamination edge sealing device suitable for the acid etching process of diffuse reflective colored glass, which aims to adopt automated means to evenly press the warped acid-proof film on the edge of the glass plate after lamination onto the side of the glass plate, thereby improving the sealing of the acid-proof coating package of the glass plate, thereby improving the yield rate of diffuse reflective colored glass.

It should be noted that the described embodiments 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.

[0027] like Figure 1-Figure 5 As shown, the present invention provides a post-coating edge sealing device suitable for a diffuse reflective colored glass acid etching process, comprising a first powered roller 11, a second powered roller 12, a first lifting mechanism 21 and a second lifting mechanism 22, wherein the first lifting mechanism 21 is arranged between the right end of the first powered roller 11 and the left end of the second powered roller 12, and the second lifting mechanism 22 is arranged at the right end of the second powered roller 12, the first lifting mechanism 21 is connected to a first lifting cross bar 31, and a pressing mechanism 1 is installed on the first lifting cross bar 31, the first powered roller 11 transfers the glass plate 3 to the right to the pressing mechanism 1, and the pressing mechanism 1 pre-presses the acid-proof film 4 with a warped right edge of the glass plate 3 on the right side of the glass plate 3; the second lifting mechanism 22 is connected to a second lifting cross bar 32, and a retaining mechanism 2 is installed on the second lifting cross bar 32, the second powered roller 12 transfers the glass plate 3 to the right to the retaining mechanism 2, and the retaining mechanism 2 presses the pre-pressed acid-proof film 4 on the right side of the glass plate 3.

[0028] The edge pressing mechanism 1 includes multiple edge pressing modules 5, which are evenly distributed on the first lifting cross bar 31; the edge pressing module 5 includes a block 51, a motor 52 and multiple guide wheels 53, the block 51 is installed on the first lifting cross bar 31, a rotating shaft 54 ​​is provided at the lower end of the block 51, and multiple guide wheels 53 are sleeved on the rotating shaft 54, the motor 52 is fixed on the block 51 and the motor 52 drives the rotating shaft 54 ​​to rotate counterclockwise, and the rotation of the rotating shaft 54 ​​drives the guide wheel 53 to rotate, and the guide wheel 53 pre-presses the acid-proof film 4 with the warped edge of the glass plate 3 on the right side of the glass plate 3.

[0029] The edge retaining mechanism 2 includes an elastic pad 201 and an electric heating plate 202. The elastic pad 201 is fixedly connected to the left side of the second lifting cross bar 32, and the electric heating plate 202 is fixedly connected to the left end face of the elastic pad 201, and is used to press the pre-pressed acid-proof film 4 to the right side of the glass plate 3. In one embodiment of the present invention, the elastic pad 201 is made of a highly elastic and heat-resistant material, so that the electric heating plate 202 can be completely fitted with the right side of the glass plate 3 after being pressed.

[0030] The principle of the present invention is as follows: the coated glass plate 3 enters the first powered roller 11, and the roller of the first powered roller 11 rotates forward. When the glass plate 3 is conveyed to the right, the first lifting cross bar 31 is lowered, so that the axis of the guide wheel 53 on the edge pressing mechanism 1 is aligned with the middle of the right side of the glass plate 3, the motor 52 is started, and the guide wheel 53 rotates slowly. Figure 6 , Figure 7 As shown, when the glass plate 3 approaches the guide wheel 53, the acid-proof film 4 on the right edge of the glass plate 3 is first subjected to the rotational friction of the guide wheel 53 and bends downward. As the glass plate 3 finally touches the guide wheel 53, the acid-proof film 4 at the contact point and its vicinity is pre-pressed on the right side of the glass plate 3; at this time, the roller of the first powered roller 11 is kept rotating forward, the glass plate 3 is blocked by the guide wheel 53, and pressure is generated on the guide wheel 53. At the same time, the reaction force overcomes the friction between the glass plate 3 and the roller, so that the glass plate 3 stops moving on the roller. After 0.5-1 second of pre-pressing, under the joint action of multiple guide wheels 53, the acid-proof film 4 on the right edge of the glass plate 3 is adhered to the right side of the glass plate 3 at intervals, and the middle interval area is still not firmly adhered; therefore, the first powered roller 11 stops and then reverses, so that the glass plate 3 moves 1-10 mm to the left, and the first lifting crossbar 31 is then raised, and the first powered roller 11 changes the conveying direction again, and conveys the glass plate 3 to the right to the second powered roller 12;

[0031] After the glass plate 3 enters the second powered roller 12, the second lifting cross bar 32 descends, and the middle of the electric heating plate 202 of the edge retaining mechanism 2 faces the right side of the glass plate 3. When the glass plate 3 touches the middle of the electric heating plate 202, the reaction force overcomes the friction between the glass plate 3 and the roller, so that the glass plate 3 stops moving on the roller and maintains the pressure on the electric heating plate 202. After pressing for 1-2 seconds, the second powered roller 12 stops and then reverses, so that the glass plate 3 runs 1-10 mm to the left. The second lifting cross bar 32 then rises, and the second powered roller 12 changes the conveying direction again, and conveys the glass plate 3 to the right to the subsequent roller.

[0032] The present invention only shows the edge sealing of one side of the glass plate 3 after coating. For the other sides of the glass plate 3, the placement direction of the glass plate 3 can be changed by a turning roller, and the edge sealing of the other sides can be completed according to the principle of the present invention.

[0033] The block body 51 includes a main body 501 and a fixed block 502. The main body 501 is composed of an upper mounting portion 511 and a lower double-ear plate 512. The first lifting cross bar 31 is arranged between the fixed block 502 and the mounting portion 511. The fixed block 502 is connected to the mounting portion 511 by screws to fix the mounting portion 511 on the first lifting cross bar 31. The two ends of the rotating shaft 54 ​​are respectively installed on the double-ear plate 512 through bearings.

[0034] A driven wheel 56 is installed at one end of the rotating shaft 54 ​​, and a driving wheel 55 is installed at the main shaft end of the motor 52 . The main shaft of the motor 52 drives the driving wheel 55 to rotate, and the driving wheel 55 drives the driven wheel 56 to rotate through a synchronous belt 57 .

[0035] The first powered roller conveyor 11 and the second powered roller conveyor 12 are both bidirectional powered roller conveyors driven by stepping motors, which can realize conveying in both forward and reverse directions.

[0036] like Figure 1 , Figure 2 , Figure 8 As shown, the first lifting mechanism 21 includes a gantry, and the two columns 211 of the gantry are respectively located on the front and rear sides of the first powered roller 11, and a lifting motor 212 is provided at the top of each column 211, and a displacement component driven by the lifting motor 212 is provided on each column 211, and the two displacement components are respectively connected to the two ends of the first lifting cross bar 31; the displacement component includes a screw nut pair 231, a slide plate 232 and a vertical slide rail 233, wherein the screw of the screw nut pair 231 is vertically arranged, one end of the slide plate 232 is connected to the nut of the screw nut pair 231, and the other end is connected to the first lifting cross bar 31, and the two sides of the slide plate 232 are respectively slidably connected to the vertical slide rail 233; the lifting motors 212 on the two columns 211 are synchronous motors.
