Description

Technical Field

[0001] This invention relates to the field of substrate glass processing technology, specifically to a device for preventing water vapor leakage in a substrate glass pre-humidification machine. Background Technology

[0002] The waterproof vapor leakage prevention device for substrate glass pre-wetting machines gradually emerged with the development of the glass deep processing industry. In the early stages, glass pre-wetting was mainly carried out through simple spraying or immersion methods, without considering the issue of waterproof vapor leakage. However, with the development of the glass processing industry and the advancement of processing technology, people began to realize the importance of waterproof vapor leakage prevention. In the early stages of the glass processing industry, people began to recognize the problem of waterproof vapor leakage and started preliminary exploration and research. At this time, people mainly used simple sealing measures to prevent moisture leakage, but the effect was not ideal. With the development and innovation of technology, some companies began to invest a lot of human and material resources in the research and development of waterproof vapor leakage prevention equipment. During this stage, some key technical problems were overcome, such as the development of sealing technology and moisture recovery and utilization. These technological breakthroughs laid the foundation for the further development of waterproof vapor leakage prevention equipment. As waterproof vapor leakage prevention equipment gradually matured and successful application cases emerged, more and more companies began to recognize its importance and began to introduce and apply this equipment on their production lines. At this time, the application scope of waterproof vapor leakage prevention equipment also continued to expand, from the initial glass deep processing industry to other fields, such as construction and automobiles.

[0003] In the substrate glass prehumidifier with patent number CN201821233224.7, cylinders located above the substrate glass inlet and outlet control the up-and-down movement of baffles. When no substrate glass is detected at the inlet or outlet, the cylinder pushes the corresponding baffle downwards, blocking the inlet or outlet. This prehumidifier, which prevents moisture leakage, has several significant drawbacks. First, it relies on sensors to detect the presence of substrate glass at the inlet and outlet, and then uses cylinders to control the baffles for sealing. In this operating mode, if the sensors malfunction and the cylinders fail to raise or lower the baffles in time, it will inevitably lead to damage to the substrate glass that is about to enter the prehumidifier or leakage of internal moisture. Second, while controlling the baffles to raise and lower them to prevent moisture leakage, there is still a certain window period during the raising or lowering process, allowing some moisture to still leak out. Finally, traditional spraying methods generally use a large amount of water for wide-area spraying, resulting in a lot of waste during spraying. They cannot accurately spray the surface of the substrate glass, and this large volume of water spraying method is also more likely to cause water vapor to leak outward. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a device for preventing water vapor leakage in a substrate glass prehumidifier. It features the ability to accurately and promptly raise a baffle based on the position of the substrate glass, and automatically return the baffle to its original position after the substrate glass passes through. Furthermore, by blowing air to raise the baffle, water vapor leaking from the inlet and outlet can be re-injected into the prehumidifier during the raising process. The device also provides precise atomized spraying based on the substrate glass's position within the prehumidifier. This not only saves water resources but also significantly reduces water vapor leakage. It solves the problem of relying on sensors to detect the presence of substrate glass at the inlet and outlet and then using a cylinder to control the baffle for sealing. In this operating mode, if the cylinder fails to raise or lower the baffle in time, it will inevitably lead to damage to the substrate glass about to enter the prehumidifier or leakage of internal water vapor. Secondly, while using a cylinder to control the baffle's up and down movement to prevent water vapor leakage, there is still a certain window period during the raising or lowering process, allowing for some leakage of internal water vapor. Finally, traditional spraying methods generally use a large amount of water for wide-area spraying, resulting in a lot of waste during spraying. They also cannot accurately spray the surface of the substrate glass, and this large amount of water spraying method is more likely to cause water vapor to leak outward.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goal of accurately and promptly raising the baffle according to the position of the substrate glass, and automatically returning the baffle to its original position after the substrate glass passes through it; and to raise the baffle by blowing air, allowing water vapor leaking from the inlet and outlet to be re-blown into the prehumidifier during the baffle raising process, and to accurately atomize and spray according to the operating position of the substrate glass inside the prehumidifier, thus saving water resources and reducing water vapor leakage, this invention provides the following technical solution: a water vapor leakage prevention device for a substrate glass prehumidifier, including a conveyor frame. 1.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a device for preventing water vapor leakage in a substrate glass pre-humidification machine, which has the following beneficial effects:

[0018] 1. This device for preventing water vapor leakage in a substrate glass pre-humidification machine utilizes the coordinated use of a front blower, a rear blower, a front baffle, and a rear baffle. When a substrate glass is about to enter conveyor frame two from conveyor frame one for pre-humidification, the front and rear blowers are constantly blowing air. However, since the substrate glass has not yet reached the blowing area, the air blown by the front blower exits through the gap between conveyor frames one and blown downwards to the right, without causing the front baffle to be lifted. As the substrate glass moves further forward and enters the blowing area, the air blown by the front blower rebounds off the substrate glass due to its obstruction. Because the angle between the front blower and the horizontal plane is greater than 90°, the air blown by the front blower is redirected upwards to the right by the rebound of the substrate glass. The air-blocking groove of the front baffle intercepts this upward-to-right airflow, creating an upward thrust on the front baffle, pushing it upwards and allowing the substrate glass to pass smoothly. Once the substrate glass has completely passed through the blowing area, the air blown by the front blower is directed downwards and to the right, as there is no longer any rebound from the substrate glass. At this point, the front baffle, lacking upward thrust, naturally falls downwards under gravity, sealing the inlet and preventing internal moisture leakage. Similarly, the combined action of the rear blower and the rear baffle ensures the substrate glass exits smoothly from the outlet, preventing moisture leakage from the prehumidifier. This achieves the effect of automatically opening and closing the baffle using the blown air, eliminating the need for sensors to detect the presence of the substrate glass, making it safer and more practical.

[0019] 2. This device for preventing water vapor leakage in a substrate glass prehumidifier utilizes the coordinated use of a front blower, a rear blower, a front baffle, and a rear baffle. The primary concern in preventing water vapor leakage is preventing leakage of water vapor from the substrate glass during entry into or exit from the prehumidifier, and during the opening and closing of the baffles. In this invention, as the front baffle is raised, the front blower continuously blows air downwards and to the right. Even after rebounding from the substrate glass, the air movement direction remains upwards and to the right. Water vapor inside the prehumidifier, wanting to leak outwards, moves to the left, thus leaking out—exactly opposite to the blowing direction. Therefore, as the baffle is raised, the water vapor about to leak outwards is blown back into the prehumidifier by the front blower. This achieves the effect of blowing leaked water vapor back into the prehumidifier during the opening and closing of the baffles.

[0020] 3. This device for preventing water vapor leakage in a substrate glass prehumidifier utilizes a combination of a front spring switch, a rear spring switch, and a follow-up spray device. When the substrate glass enters the prehumidifier, the first two corners of the substrate glass compress the two front spring switches inward. Once the two front spring switches are fully compressed, the follow-up spray device begins operation. The spray belt on the follow-up spray device rotates under the drive of a motor, spraying water directly onto the surface of the substrate glass. As the substrate glass moves forward, the spray belt also moves forward under the drive of the motor, ensuring that the sprayed water is always directly above the substrate glass. This spraying method significantly reduces water consumption, unlike traditional large-scale spraying, and reduces water vapor generation inside the prehumidifier. This achieves water conservation and is more effective in cleaning the substrate glass while reducing water vapor generation. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-6 A device for preventing water vapor leakage in a substrate glass pre-humidification machine includes a conveyor frame 1, a conveyor frame 2, a conveyor frame 3, and a pre-humidification machine 5. The conveyor frame 1 is sequentially and fixedly connected to the conveyor frame 2 and the conveyor frame 3. The pre-humidification machine 5 is fixedly installed on the conveyor frame 2. The conveyor frame 1 can stably convey the substrate glass 4 processed from other processes into the pre-humidification machine 5. The conveyor frame 3 can transport the pre-humidified substrate glass 4 to the next process, forming a complete production line operation.

[0038] The prehumidifier 5 includes a prehumidifier housing 51, which is integrally molded to ensure that internal moisture does not leak out due to gaps in the housing during prehumidification of the substrate glass 4. This is because the temperature and pressure of the moisture change during prehumidification; if gaps exist between the housings, moisture may escape, reducing the prehumidification effect. The integrally molded housing 51 effectively prevents this, ensuring that moisture is fully utilized within the prehumidifier 5 for better prehumidification.

[0039] The prehumidifier housing 51 has baffle grooves 57 machined on both the front and rear end faces. A front baffle 54 and a rear baffle 56 are slidably mounted in the baffle grooves 57. The front baffle 54 and the rear baffle 56 are slidably installed in the baffle grooves 57. This installation method not only allows the front baffle 54 and the rear baffle 56 to be lifted upward under the propulsion of airflow, but also ensures that after the lifting force of airflow is lost, the front baffle 54 and the rear baffle 56 can automatically fall down due to gravity, sealing the inlet and outlet of the prehumidifier 5 and preventing internal water vapor leakage.

[0040] A front blower 52 and a rear blower 55 are fixedly installed on the prehumidifier housing 51 above the baffle slide 57. The front blower 52 and rear blower 55 are typically fixedly installed on the upper part of the prehumidifier housing 51, just above the front baffle 54 and rear baffle 56. This positioning allows them to effectively blow away dust and impurities adhering to the surface of the substrate glass 4 as it enters the prehumidifier 5. Through strong or weak airflow, the substrate glass 4 is ensured to enter the prehumidifier 5 in a "clean" state. In addition, the front blower 52 and rear blower 55 play an important role in the movement of the substrate glass 4. Due to their proper position and angle design, they can provide a stable upward thrust to the front baffle 54 and rear baffle 56 as the substrate glass 4 moves. This thrust not only helps the substrate glass 4 enter the prehumidifier 5 smoothly but also reduces the possibility of damage to the substrate glass 4 due to the baffles.

[0041] The prehumidifier 5 has a baffle 53 machined inside its outer casing 51. This baffle 53 is machined at the front end of the rear air blower 55, and it can block most of the water vapor sprayed out by the spraying device 6, ensuring that the rear air blower 55 will not carry water vapor out when blowing air.

[0042] A front spring switch 21 and a rear spring switch 22 are fixedly installed at the front and rear ends of the side of the conveyor frame 2, respectively. The front spring switch 21 and the rear spring switch 22 can control the start and stop of the following spray device 6 according to the position of the substrate glass 4 when it enters the conveyor frame 2 for pre-wetting.

[0043] The front baffle 54 and the rear baffle 56 have the same structure. A semi-circular rubber pad 542 is fixedly installed at the bottom of the front baffle 54, covering the bottom edge of the front baffle 54. A wind-blocking groove 541 is machined on the side of the front baffle 54, and the cross-section of the wind-blocking groove 541 is semi-annular. The wind-blocking groove 541 can block the wind that bounces off the substrate glass 4, thereby creating an upward thrust on the wind-blocking groove 541, which in turn pushes the front baffle 54 or the rear baffle 56 upward. The rubber pad 542 installed at the bottom of the baffle can prevent the front baffle 54 or the rear baffle 56 from scratching the substrate glass 4 when it comes into contact with it, thus preventing damage to the substrate glass 4 and increasing processing costs.

[0044] The outlets of the front air blower 52 and the rear air blower 55 are at an angle greater than 90° to the horizontal plane. The gas blown by the front air blower 52 and the rear air blower 55 bounces upwards and to the right after encountering the substrate glass 4. This angle of greater than 90° allows the bounced gas to move upwards and to the right when blowing air onto the substrate glass 4, meaning the bounced gas is directed towards the air baffle 541, thus creating an upward thrust on the front baffle 54 or the rear baffle 56.

[0045] The distance between the front spring switch 21 and the rear spring switch 22 is less than or equal to the length of the side of the substrate glass 4. Setting the distance between the front spring switch 21 and the rear spring switch 22 to be less than or equal to the length of the side of the substrate glass 4 ensures that when the substrate glass 4 enters the conveyor frame 2 for pre-wetting, the substrate glass 4 can compress at least one pair of front spring switches 21 or rear spring switches 22, thereby ensuring that when the substrate glass 4 is inside the pre-wetting machine 5, it can maintain the operation of the spray device 6.

[0046] A follow-up spray device 6 is fixedly installed on the inner side of the prehumidifier housing 51. The follow-up spray device 6 is fixedly installed on the inner side of the prehumidifier housing 51 via a mounting bracket 62. The follow-up spray device 6 includes a motor 61 and a spray belt 64. The motor 61 is fixedly installed at both ends of the mounting bracket 62, and the spray belt 64 is mounted on two motors 61. A water inlet pipe 63 is installed between the two motors 61. Spray holes 641 are machined along half the length of the spray belt 64. The angle between the spray surface of the spray belt 64 and the upper surface of the substrate glass 4 is less than 90°. The running speed of the spray belt 64 is equal to the running speed of the substrate glass 4 on the conveyor frame 2. With this configuration, the water sprayed from the spray holes 641 accurately sprays onto the surface of the substrate glass 4 during the spraying process. This spraying is continuous because the spray belt 64 moves synchronously with the substrate glass 4 under the drive of the motor 61. This ensures that the sprayed water always hits directly above the substrate glass 4. After the section of the belt with spray holes 641 finishes its journey, the other section of the belt without spray holes 641 moves to the spraying side, where spraying ceases. Because the distance between each pair of substrate glass 4 is relatively large when they enter the pre-humidifier 5, this prevents damage between them. Therefore, it is crucial to ensure that no spraying occurs in areas where no substrate glass 4 passes, further reducing water waste. Intermittent spraying is achieved through the half-spray holes 641 machined on the spray belt 64. When a substrate glass 4 passes, the belt with spray holes 641 moves to the front and sprays; during the interval between two substrate glass 4s, the belt without spray holes 641 moves to the front and does not spray. Furthermore, this spraying method, where the spray holes 641 move forward at the same speed as the substrate glass 4, ensures accurate spraying of the substrate glass 4 at all times, improving spraying efficiency.

[0047] Please see Figure 7-10 When the substrate glass 4 steadily enters the prehumidifier 5, its front end will first encounter two front spring switches 21. These two spring switches are designed to deform at this moment in response to the weight of the substrate glass 4. Due to the weight of the substrate glass 4, these two spring switches will be compressed inward. This compression mechanism is part of the prehumidifier 5 and is used to trigger the activation of the follow-up spray device 6.

[0048] When the two front spring switches 21 are fully compressed, a mechanical signal is triggered, and the follow-up spray device 6 begins to operate. This follow-up spray device 6 is a precision mechanical system comprising a spray belt 64 and a drive motor 61. Upon receiving the mechanical signal, the motor 61 starts operating, driving the spray belt 64 to rotate. At this time, the water sprayed from the spray holes 641 is accurately sprayed onto the surface of the substrate glass 4. This spraying is continuous because the spray belt 64 moves synchronously with the substrate glass 4 under the drive of the motor 61. This ensures that the sprayed water is always sprayed directly above the substrate glass 4.

[0049] The substrate glass 4 continues to move forward. As the spring switch is compressed, the follow-up spray device 6 continues to spray water. However, as the substrate glass 4 moves forward, it also compresses the rear spring switch 22. Thus, the follow-up spray device 6 is in a state where the front spring switch 21 is released, but the rear spring switch 22 remains compressed, and the follow-up spray device 6 continues to operate. This state continues until the substrate glass 4 has completely left the conveyor frame 2.

[0050] Then, the substrate glass 4 continues to move forward, completely leaving the conveyor frame 2. At this point, the rear spring switch 22 will also release, and the spraying device 6 will stop spraying. This process is automatic and is entirely controlled by the position of the substrate glass 4 and the mechanical design of the spring switch. This design ensures that the spray water is only sprayed onto the substrate glass 4 that needs pre-wetting, avoiding waste and contamination.

[0051] Please see Figure 11-14 When the substrate glass 4 is about to enter the second conveyor 2 from the first conveyor 1 for pre-wetting, the front blower 52 and the rear blower 55 are constantly blowing air. However, at this time, the substrate glass 4 has not yet reached the blowing area, so the gas blown from the front blower 52 is blown out to the lower right through the gap between the first and second conveyor 1. At this stage, the blown gas does not directly act on the front baffle 54, but forms a gas barrier to prevent the front baffle 54 from being accidentally blown up or lifted.

[0052] As the substrate glass 4 moves further forward, it gradually enters the blowing area. In this area, the front air blower 52 begins to blow air onto the substrate glass 4. Due to the reflectivity of the surface of the substrate glass 4, the gas blown by the front air blower 52 bounces off the substrate glass 4. Since the angle between the front air blower 52 and the horizontal plane is greater than 90°, the gas blown by the front air blower 52 bounces off the substrate glass 4 and is blown upwards and to the right.

[0053] At this critical moment, the air duct 541 of the front baffle 54 intercepts the air blown upwards and to the right. The intercepted air creates an upward thrust on the front baffle 54, pushing it upwards. This thrust allows the substrate glass 4 to pass smoothly through the gap between the first conveyor and the second conveyor and enter the pre-wetting area.

[0054] After the substrate glass 4 has completely passed through the blowing area, the gas blown by the front air blower 52 is blown downwards and to the right. At this time, since there is no rebound from the substrate glass 4, the front baffle 54 loses its upward thrust. Under the action of gravity, the front baffle 54 naturally falls downwards, sealing the inlet and thus preventing internal moisture leakage.

[0055] Meanwhile, the rear air blower 55 and the rear baffle 56 also play the same role. The rear air blower 55 blows air towards the back of the substrate glass 4 as it passes by, helping the substrate glass 4 to move smoothly. After the substrate glass 4 has completely left the conveyor frame 2, the rear baffle 56 also falls downwards under the action of gravity, sealing the outlet and thus ensuring that water vapor inside the prehumidifier 5 does not leak.

[0056] Working principle: When the substrate glass 4 is about to enter the second conveyor 2 from the first conveyor 1 for pre-wetting, the front air blower 52 and the rear air blower 55 are constantly blowing air. The substrate glass 4 moves forward further. When the substrate glass 4 enters the blowing area, the air blown by the front air blower 52 bounces off the substrate glass 4 due to the obstruction of the substrate glass 4. Since the angle between the front air blower 52 and the horizontal plane is greater than 90°, the air blown by the front air blower 52 is blown to the upper right after being bounced off the substrate glass 4. The wind-blocking groove 541 of the front baffle 54 intercepts this air blown to the upper right. This air forms an upward thrust on the front baffle 54, pushing the front baffle 54 upward so that the substrate glass 4 can pass smoothly. Once the substrate glass 4 has completely passed through the blowing area, the air blown out by the front air blower 52 is directed downwards and to the right due to the absence of rebound from the substrate glass 4. At this point, the front baffle 54, lacking upward thrust, naturally falls downwards under gravity, sealing the inlet. The substrate glass 4 then enters the pre-humidifier 5 for pre-humidification.

[0057] When the substrate glass 4 enters the prehumidifier 5 for prehumidification, the two corners of the substrate glass 4 first enter the prehumidifier 5, compressing the two front spring switches 21 inward. Once the two front spring switches 21 are fully compressed, the follow-up spray device 6 starts operating. The spray belt 64 on the follow-up spray device 6 begins to rotate under the drive of the motor 61. At this time, the water sprayed from the spray holes 641 is sprayed directly onto the surface of the substrate glass 4. As the substrate glass 4 moves forward, the spray belt 64 also moves forward under the drive of the motor 61, so the sprayed water is always sprayed directly above the substrate glass 4. This spraying method greatly reduces the amount of water used, unlike traditional large-scale spraying, and reduces the generation of water vapor inside the prehumidifier 5.

[0058] After the substrate glass 4 is pre-humidified, it is conveyed out of the pre-humidifier 5. In the same manner as entering the pre-humidifier 5, the rear baffle 56 is lifted by the rear air blower 55, and then the substrate glass 4 is transported out, and the rear baffle 56 falls down. This completes the pre-humidification of the substrate glass 4 and prevents moisture leakage.

[0059] Similarly, the combined action of the rear air blower 55 and the rear baffle 56 ensures that the substrate glass 4 is smoothly transported out of the outlet and prevents water vapor from leaking out of the prehumidifier 5.
