Description

Technical Field

[0001] This utility model relates to the field of AG glass processing technology, specifically to a mechanism for uniformly spraying etching solution in the production of AG etched glass. Background Technology

[0002] Anti-reflective glass (AG glass) is a special type of glass whose light reflectivity is reduced to below 1% through surface processing technology. It is mainly used in building facades, solar photovoltaic modules, and optical instruments. Its core production processes include three types: chemical etching, coating, and spraying. Anti-glare functionality is achieved by forming a diffuse reflective surface or microstructure layer. AG glass requires an etching process using a spray etching solution. The spray etching method can use a tank with a large capacity, allowing for easy removal of reaction products and continuous flow of the etchant through the tank and etching space. Furthermore, the spray method effectively maintains excellent surface quality, and because the etchant can be continuously used to treat reaction products, the amount of etchant used is reduced. However, because the spray method can only process glass substrates one at a time, its production efficiency is relatively low.

[0003] Prior art includes an apparatus for etching glass sheets and a glass sheet made using the same apparatus, as disclosed in patent application number 201210082749.6. The apparatus comprises a fixing device disposed under one or more glass substrates and separable from the ground at a predetermined angle, for fixing and supporting the glass substrates; and a spraying device disposed on the glass substrates for spraying an etchant onto the glass substrates. The spraying device includes one or more nozzles and one or more spray heads for spraying the etchant. The end nozzles are positioned at a predetermined distance from the glass substrate, the distance being determined by the spacing between the nozzles and the etchant spraying angle. However, this method requires a large number of spray nozzles to achieve large-area spraying, and the spraying uniformity is poor. Utility Model Content

[0004] The purpose of this invention is to provide a uniform spraying mechanism for etching solution in AG etched glass production, so as to solve the problem that the existing technology requires a large number of spraying pipes to achieve large-area spraying and the spraying uniformity is poor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniform coating mechanism for etching solution in AG etched glass production, comprising a first mounting frame and a second mounting frame. Two transverse sliding blocks are slidably disposed on the inner sides of the first and second mounting frames via a lead screw and a guide rod. Two sets of transverse supports are also provided between the two transverse sliding blocks. Multiple coating pipes are rotatably disposed at the lower part of each transverse support. One end of each coating pipe is connected to a main infusion pipe and an infusion pump via a connecting hose. An oscillating spraying drive mechanism for driving the multiple coating pipes to rotate and oscillate horizontally is provided inside the transverse support. The oscillating spraying drive mechanism includes an eccentric transmission mechanism connected via a gear and rack assembly.

[0006] Furthermore, both the first mounting bracket and the second mounting bracket are configured as U-shaped brackets, and the inner walls of the first mounting bracket and the second mounting bracket are provided with mounting holes.

[0007] Furthermore, the lead screw includes a lead rod rotatably disposed in the middle of the first mounting bracket, and two opposite sets of external threads are provided on the outer sides of both ends of the lead rod, and a first motor is drivenly connected to one end of the lead rod.

[0008] Furthermore, the multiple spray pipes are arranged in parallel longitudinally, and multiple spray nozzles are provided on one side of each spray pipe.

[0009] Furthermore, the gear and rack assembly includes a driven gear disposed at one end of the spray pipe, an active rack is elastically slidably disposed in the limiting groove of the inner wall of the transverse support, and the active rack is meshed with the driven gear. The eccentric transmission mechanism includes a second motor disposed inside one end of the transverse support, and an eccentric wheel for laterally pressing the active rack is provided at one end of the second motor.

[0010] Furthermore, the inner wall of the limiting groove is provided with a guide rod and a spring, and one end of the active rack is provided with a limiting hole that slides into the guide rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model has multiple spray pipes rotating under a transverse support, and a swing spraying drive mechanism is provided inside the transverse support. The swing spraying drive mechanism can drive multiple spray pipes to rotate and swing horizontally for spraying, which increases the spraying area of ​​a single pipe. A large area can be sprayed with a smaller number of spray pipes, and the spraying uniformity is strong.

[0013] 2. The present invention further includes an eccentric transmission mechanism connected by a gear and rack assembly. The gear and rack assembly includes a driven gear at one end of the spray tube, and an active rack is elastically slidably disposed in a limiting groove on the inner wall of the transverse support, and the active rack is meshed with the driven gear. The eccentric transmission mechanism includes a second motor disposed inside one end of the transverse support, and an eccentric wheel at one end of the second motor for laterally pressing the active rack. The eccentric wheel is driven by the second motor to rotate at a uniform speed, and the eccentric wheel presses the active rack to move laterally. Then the active rack is reset under the action of a spring, thereby achieving the purpose of driving the active rack to move back and forth laterally. The active rack drives the driven gear and the spray tube to rotate back and forth, thereby achieving the purpose of reciprocating rotational spraying. The transmission stability is high and the operation is convenient and quick.

[0014] 3. In this utility model, two transverse sliding blocks are provided in the first and second mounting brackets through a lead screw and a guide rod, and two sets of transverse supports are provided between the two transverse sliding blocks. The lead screw includes a lead rod rotatably set in the middle of the first mounting bracket. Two sets of opposite external threads are provided on the outer sides of the two ends of the lead rod, so that the two transverse sliding blocks can be moved in opposite directions by the lead screw to adjust the distance between the two sets of spray tubes, thereby facilitating the adjustment of the spray distance between the spray tube and the glass.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the present invention, an etching solution uniform spraying mechanism for AG etched glass production includes a first mounting frame 1 and a second mounting frame 2. Both the first mounting frame 1 and the second mounting frame 2 are configured as U-shaped frames, and the inner walls of the first mounting frame 1 and the second mounting frame 2 are provided with mounting holes to facilitate the installation of the equipment on the top of the spraying chamber with screws. Two transverse sliding blocks 8 are slidably provided on the inner sides of the first mounting frame 1 and the second mounting frame 2 through a lead screw and a guide rod 4, and two sets of transverse supports 5 are provided between the two transverse sliding blocks 8. Multiple spraying pipes 6 are rotatably provided at the lower part of the transverse supports 5. The multiple spraying pipes 6 are arranged longitudinally in parallel, and multiple nozzles 9 are provided on one side of the spraying pipes 6 to facilitate spraying on both sides of the glass. Multiple spraying pipes 6 are connected at one end to a main infusion pipe 11 and an infusion pump 12 via a connecting hose 10 for uniform spraying. The etching solution in the storage tank is absorbed through the connecting hose 10, the main infusion pipe 11, and the infusion pump 12, and then sprayed out from the nozzle 9 on one side of the spraying pipe 6 to etch the glass that slowly passes between two sets of spraying pipes 6. The transverse support 5 is equipped with a swing spraying drive mechanism for driving the multiple spraying pipes 6 to rotate and swing horizontally. This allows the multiple spraying pipes 6 to be driven to rotate and swing horizontally for spraying, increasing the spraying area of ​​a single pipe. This makes it easier to achieve large-area spraying with a smaller number of spraying pipes, and the spraying uniformity is also strong.

[0023] like Figure 3 and Figure 4As shown, in order to achieve the purpose of reciprocating rotary spraying, the oscillating spraying drive mechanism also includes an eccentric transmission mechanism connected by a gear and rack assembly. The gear and rack assembly includes a driven gear 13 disposed at one end of the spraying pipe 6, and an active rack 14 elastically sliding within a limiting groove 15 on the inner wall of the transverse support 5, with the active rack 14 meshing with the driven gear 13. The eccentric transmission mechanism includes a second motor 17 disposed inside one end of the transverse support 5, and an eccentric wheel 16 for laterally pressing the active rack 14 at one end of the second motor 17. The inner wall of the limiting groove 15 is provided with... It has a guide rod 18 and a spring 19, and one end of the active rack 14 is provided with a limiting hole that slides into the guide rod 18. This allows the eccentric wheel 16 to rotate at a constant speed driven by the second motor 17. The eccentric wheel 16 horizontally presses the active rack 14 to move laterally. Then, the active rack 14 is reset under the action of the spring 19, thereby achieving the purpose of driving the active rack 14 to move back and forth laterally. The active rack 14 drives the driven gear 13 and the spray pipe 6 to rotate back and forth in both directions, with a rotation range of 15-30°, thereby achieving the purpose of reciprocating rotational spraying. It has high transmission stability and is convenient and quick to operate.

[0024] like Figure 1 and Figure 2 As shown, in order to adjust the distance between the two sets of spray pipes 6, a lead screw including a lead screw 3 rotatably set in the middle of the first mounting bracket 1 is also included. The two ends of the lead screw 3 are provided with two opposite sets of external threads. One end of the lead screw 3 is connected to a first motor 7, so that the two transverse sliders 8 are moved towards each other by the lead screw to adjust the distance between the two sets of spray pipes 6, thereby facilitating the adjustment of the spraying distance between the spray pipe 6 and the glass.

[0025] The working principle and usage process of this utility model are as follows: In use, the first mounting bracket 1 and the second mounting bracket 2 are installed on the top of the spraying chamber, and the two sets of spraying pipes 6 are set on both sides of the glass conveying channel. The etching liquid in the storage tank is absorbed by the connecting hose 10, the main infusion pipe 11 and the infusion pump 12, and sprayed out by the nozzle 9 on one side of the spraying pipe 6 to etch the glass that slowly passes between the two sets of spraying pipes 6. At the same time, the swing spraying drive mechanism can drive multiple spraying pipes 6 to rotate and swing horizontally for spraying, which increases the spraying area of ​​a single pipe. It is convenient to set a small number of spraying pipes to achieve large-area spraying, and the spraying uniformity is strong.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
