Description

Technical Field

[0001] This invention relates to the field of vacuum glass manufacturing technology, specifically to a simple and energy-saving vacuum glass preparation device. Background Technology

[0002] Vacuum glass, as a new type of energy-saving insulation material, is widely used in building curtain walls, doors and windows, and appliance panels due to its excellent heat and sound insulation properties and its thin and lightweight structure. The core structure of vacuum glass consists of two parallel glass substrates with a vacuum chamber between them. Support structures are installed within the chamber to resist atmospheric pressure and prevent deformation of the glass substrates. Simultaneously, the edges of the glass substrates are sealed to ensure the airtightness of the vacuum chamber, thus maintaining its energy-saving performance over long-term use. Therefore, the quality of the support structure installation and the reliability of the edge-sealing process directly determine the mechanical stability, sealing performance, and service life of the vacuum glass.

[0003] Currently, in the fabrication of vacuum glass, the placement of supports largely relies on manual spreading. Manual spreading makes it difficult to precisely control the spacing of the supports, resulting in poor uniformity of distribution, large spacing errors, and the potential for missing supports in some areas. This causes uneven stress on the glass substrate under atmospheric pressure, leading to deformation and, in severe cases, glass breakage. Furthermore, the adhesion between manually spread supports and the glass substrate is poor, making them prone to displacement during subsequent edge sealing, heating, and vacuum treatment. This causes the supports to deviate from their intended position, rendering them ineffective. Many simplified fabrication processes use manual application of low-melting-point glass powder for edge sealing. However, manual application makes it difficult to precisely control the thickness of the edge, resulting in uneven thickness and defects such as gaps and bubbles at the sealing edge. These defects directly compromise the seal of the vacuum glass edges, allowing air to easily penetrate the vacuum chamber and reduce its vacuum level. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a simple and energy-saving vacuum glass preparation device, which solves the problems of uneven distribution of the support and uneven coating of sealing glass powder in the existing vacuum glass preparation process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a simple energy-saving vacuum glass preparation device, comprising a base plate and a vertical rail fixedly connected to the base plate. A lifting seat is slidably connected within the vertical rail. A dispensing plate is fixedly connected to the end of the lifting seat away from the vertical rail. Multiple T-shaped plates are evenly rotatably connected to the end of the dispensing plate away from the base plate. A dispensing port is provided on the dispensing plate. Multiple limiting plates are evenly fixedly connected within the dispensing port. Multiple supporting grids are placed between the multiple limiting plates. An arc-shaped plate is fixedly connected to the end of the T-shaped plate away from the dispensing plate. A connecting plate is rotatably connected between every two T-shaped plates. A sliding rod is installed near the four corners of the dispensing plate and is slidably connected to the dispensing plate. A contact plate is fixedly connected to the end of the sliding rod near the base plate. A limiting frame is fixedly connected between the multiple contact plates. A second slide rail is fixedly connected to the end of the limiting frame near the vertical rail. A second slide block is slidably connected within the second slide rail. A scraper is fixedly connected to the end of the second slide block away from the vertical rail, and the scraper is adapted to the limiting frame.

[0006] Preferably, the upper surface of the base plate is fixedly connected to two side plates, and two rotating shafts are rotatably connected between the two side plates. The outer walls of the two rotating shafts are jointly fitted with a conveyor belt.

[0007] Preferably, a second adsorption plate is uniformly and fixedly connected to the conveyor belt, and a lower glass sheet is adsorbed at the end of the second adsorption plate away from the conveyor belt. A support frame is fixedly connected between the two side plates.

[0008] Preferably, two mounting columns are fixedly connected to the upper surface of the base plate, and the ends of the two mounting columns away from the base plate are jointly fixedly connected to a first slide rail.

[0009] Preferably, a first slide block is slidably connected inside the first slide rail, and a first threaded rod is rotatably connected inside the first slide rail, with the first slide block and the first threaded rod being threadedly connected.

[0010] Preferably, a support plate is fixedly connected to the end of the first slide block away from the first slide rail, an electric telescopic rod is fixedly connected to the support plate, a first adsorption plate is fixedly connected to the output end of the electric telescopic rod, and an upper glass sheet is adsorbed at the end of the first adsorption plate near the lower glass sheet.

[0011] Preferably, a vertical plate is fixedly connected to the upper surface of the base plate, and a rubber wheel and a cleaning roller are rotatably connected to the end of the vertical plate near the conveyor belt.

[0012] Preferably, a hydraulic push rod is fixedly connected inside the vertical rail, the output end of the hydraulic push rod is fixedly connected to the lifting seat, and a compression spring is sleeved on the outer wall of the slide rod, with the compression spring located between the delivery plate and the contact plate.

[0013] Preferably, a feeding ring is fixedly connected to the lower surface of the feeding plate, a second threaded rod is rotatably connected inside the second slide rail, and the second slide block is threadedly connected to the second threaded rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention uses a cleaning roller to automatically clean the bonding ends of the upper and lower glass sheets, preventing dust and impurities from affecting the vacuum. A rubber wheel can coat the surface of the lower glass sheet with adhesive. A hydraulic push rod drives a contact plate to abut against the bonding end of the lower glass sheet, reducing the gap between the support grid and the lower glass sheet and improving the accuracy of the support grid placement. The connecting plate is pushed to make multiple T-shaped plates rotate simultaneously, so that the support grid is automatically placed and stably placed on the lower glass sheet under the action of adhesive, avoiding the support grid from shifting during subsequent processing and effectively improving the uniformity of the support distribution.

[0016] 2. In this invention, the contact plate abuts against the lower glass sheet, so that the limiting frame and the upper surface of the lower glass sheet are tightly fitted. At the same time, the discharge port of the feeding ring automatically discharges low melting point glass powder into the limiting frame. The scraper moves along the upper surface of the limiting frame to automatically flatten the low melting point glass powder, improve the uniformity of the distribution of low melting point glass powder, and avoid uneven thickness of the frame, which can easily cause defects such as gaps and bubbles at the sealing edge.

[0024] 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.

[0025] refer to Figures 1-6 The present invention relates to a simple energy-saving vacuum glass preparation device, comprising a base plate 1 and a vertical rail 4 fixedly connected to the base plate 1, as shown in the following specific embodiment:

[0026] Example 1

[0027] A lifting seat 23 is slidably connected inside the vertical rail 4. A delivery plate 7 is fixedly connected to the end of the lifting seat 23 away from the vertical rail 4. Multiple T-shaped plates 26 are evenly rotatably connected to the end of the delivery plate 7 away from the bottom plate 1. A delivery port 25 is opened on the delivery plate 7. Multiple limiting plates 22 are evenly fixedly connected inside the delivery port 25. Multiple supporting grids 24 are placed between the multiple limiting plates 22. An arc plate 27 is fixedly connected to the end of the T-shaped plate 26 away from the delivery plate 7. A connecting plate 28 is rotatably connected between every two T-shaped plates 26. A sliding rod 30 is installed near the four corners of the delivery plate 7 and is slidably connected to the delivery plate 7. A hydraulic push rod 21 is fixedly connected inside the vertical rail 4. The output end of the hydraulic push rod 21 is fixedly connected to the lifting seat 23.

[0028] By controlling the retraction of the hydraulic push rod 21, the height of the lifting seat 23 and the delivery plate 7 is reduced, narrowing the distance between them and the lower glass plate 13. This prevents the distance from being too large, which could cause the support grid 24 to shift during delivery. The drive rod, which is matched with one of the connecting plates 28, pushes the connecting plate 28 to move, thereby synchronously driving multiple T-shaped plates 26 and arc-shaped plates 27 to rotate synchronously. The T-shaped plates 26 and arc-shaped plates 27 are staggered. The T-shaped plates 26 move away from the delivery port 25. When the T-shaped plates 26 are completely rotated away from the delivery port 25, multiple T-shaped plates 26 together... The placed support grid 24, lacking the support of the T-shaped plate 26, automatically falls from the inlet 25 onto the surface of the lower glass plate 13. During the process of the T-shaped plate 26 moving away from the inlet 25, the arc plate 27 rotates above the inlet 25, and the thickness of the support grid 24 is the same as that of the T-shaped plate 26. Multiple arc plates 27 support the support grid 24 located above the arc plate 27. The above operation is repeated. As the T-shaped plate 26 rotates into the inlet 25, the arc plate 27 rotates away from the inlet 25, and the support grid 24 automatically falls onto the T-shaped plate 26.

[0029] Example 2

[0030] Two side plates 2 are fixedly connected to the upper surface of the base plate 1. Two rotating shafts 14 are rotatably connected between the two side plates 2. A conveyor belt 11 is sleeved on the outer wall of the two rotating shafts 14. A second adsorption plate 16 is evenly fixedly connected to the conveyor belt 11. A lower glass sheet 13 is adsorbed at the end of the second adsorption plate 16 away from the conveyor belt 11. A support frame 15 is fixedly connected between the two side plates 2. A vertical plate 3 is fixedly connected to the upper surface of the base plate 1. A rubber wheel 19 and a cleaning roller 20 are rotatably connected to the end of the vertical plate 3 near the conveyor belt 11.

[0031] The lower glass sheet 13 is adsorbed and fixed by the second adsorption plate 16 on the conveyor belt 11 to prevent movement during the conveying process. The drive motor matched with the rotating shaft 14 drives it to rotate, which in turn drives the conveyor belt 11 to rotate. The drive motor matched with the cleaning roller 20 drives it to rotate. Since the cleaning roller 20 and the rubber wheel 19 are connected by a belt, the rubber wheel 19 is driven to rotate. The cleaning roller 20 first cleans the bonding end of the lower glass sheet 13, and the rubber wheel 19 automatically applies glue to the bonding end.

[0032] Example 3

[0033] A contact plate 32 is fixedly connected to one end of the slide rod 30 near the base plate 1. A limiting frame 33 is fixedly connected between multiple contact plates 32. A compression spring 31 is sleeved on the outer wall of the slide rod 30, and the compression spring 31 is located between the feeding plate 7 and the contact plate 32. A second slide rail 34 is fixedly connected to one end of the limiting frame 33 near the vertical rail 4. A second slide block 36 is slidably connected inside the second slide rail 34. A scraper 35 is fixedly connected to one end of the second slide block 36 away from the vertical rail 4, and the scraper 35 is adapted to the limiting frame 33. A feeding ring 29 is fixedly connected to the lower surface of the feeding plate 7. A second threaded rod 37 is rotatably connected inside the second slide rail 34, and the second slide block 36 is threadedly connected to the second threaded rod 37.

[0034] By controlling the retraction of the hydraulic push rod 21, the limiting frame 33 and the contact plate 32 abut against the contact end of the lower glass sheet 13. Both the limiting frame 33 and the contact plate 32 abut against the lower glass sheet 13, and rubber pads are provided at the contact ends of both to prevent damage to the lower glass sheet 13. As the feeding plate 7 moves, the slide rod 30 moves upward along the feeding plate 7. At this time, the compression spring 31 is in a compressed state, and the elastic force of the compression spring 31 will not damage the lower glass sheet 13. When the feeding ring 29 approaches the limiting frame 33, low melting point glass powder is automatically fed into the limiting frame 33, and the drive motor matched with the second threaded rod 37 drives the scraper 35 to automatically scrape the low melting point glass powder in the limiting frame 33, thereby improving the uniformity of the distribution of low melting point glass powder.

[0035] Example 4

[0036] Two mounting posts 5 are fixedly connected to the upper surface of the base plate 1. The ends of the two mounting posts 5 away from the base plate 1 are fixedly connected to a first slide rail 6. A first slide block 18 is slidably connected inside the first slide rail 6. A first threaded rod 17 is rotatably connected inside the first slide rail 6, and the first slide block 18 is threadedly connected to the first threaded rod 17. A support plate 8 is fixedly connected to the end of the first slide block 18 away from the first slide rail 6. An electric telescopic rod 10 is fixedly connected to the support plate 8. A first adsorption plate 9 is fixedly connected to the output end of the electric telescopic rod 10. An upper glass plate 12 is adsorbed at the end of the first adsorption plate 9 near the lower glass plate 13.

[0037] After the support grid 24 and low-melting-point glass powder are placed, the hydraulic push rod 21 is extended to move the feeding plate 7 away from the conveyor belt 11, avoiding affecting the subsequent movement of the upper glass sheet 12. The drive motor matched with the first threaded rod 17 drives the first slide block 18 to move along the first slide rail 6. As the first slide block 18 moves, the support plate 8 and the upper glass sheet 12 move synchronously. During the movement, the cleaning roller 20 cleans the contact end of the upper glass sheet 12. When the upper glass sheet 12 moves directly above the lower glass sheet 13, the electric telescopic rod 10 pushes the upper glass sheet. The upper glass plate 12 is bonded to the lower glass plate 13, while the first adsorption plate 9 releases its adsorption on the upper glass plate 12. At the same time, the upper glass plate 12 presses against the support grid 24, making the support grid 24 and the lower glass plate 13 fit more tightly. The upper glass plate 12 and the lower glass plate 13 are placed in a heating furnace, and the low melting point glass powder is heated to melt it. After cooling, a sealed frame is formed. A vacuum pump is connected to the vacuum pump through a pre-reserved air extraction hole on the sealed frame. The vacuum pump is started to extract the air in the chamber. After the vacuum degree reaches the standard, the air extraction hole is heat-sealed to completely isolate the outside air.

[0038] The working principle of this invention is as follows: A drive motor, matched with the rotating shaft 14, drives the conveyor belt 11 to rotate. The second adsorption plate 16 on the conveyor belt 11 adsorbs and fixes the lower glass sheet 13. A drive motor, matched with the cleaning roller 20, drives it to rotate, which in turn drives the rubber wheel 19 to rotate. The cleaning roller 20 first cleans the bonding end of the lower glass sheet 13, and the rubber wheel 19 automatically applies glue to its bonding end. The hydraulic push rod 21 is controlled to retract, lowering the height of the lifting seat 23 and the delivery plate 7. A drive rod matched with one of the connecting plates 28 pushes the connecting plate 28 to move, thereby... The step drive rotates multiple T-shaped plates 26 and arc-shaped plates 27 synchronously. When the T-shaped plates 26 are completely rotated away from the feeding port 25, the support grid 24 automatically falls from the feeding port 25 onto the surface of the lower glass sheet 13 due to the lack of support from the T-shaped plates 26. During the process of the T-shaped plates 26 rotating away from the feeding port 25, the arc-shaped plates 27 rotate to above the feeding port 25. Multiple arc-shaped plates 27 support the support grid 24 located above the arc-shaped plates 27. The limiting frame 33 and the contact plate 32 abut against the contact end of the lower glass sheet 13. When the feeding ring 29 approaches the limiting frame 33, it automatically moves towards the limiting frame 33. Low-melting-point glass powder is added to the inner 3, and the scraper 35 is driven by the drive motor of the second threaded rod 37 to automatically scrape the low-melting-point glass powder in the limiting frame 33. After the support grid 24 and the low-melting-point glass powder are placed, the hydraulic push rod 21 is extended to move the feeding plate 7 away from the conveyor belt 11. The drive motor of the first threaded rod 17 drives the first slide block 18 to move along the first slide rail 6. As the first slide block 18 moves, the support plate 8 and the upper glass sheet 12 move synchronously. During the movement, the cleaning roller 20 adheres to the upper glass sheet 12. The upper glass plate 12 is cleaned, and when it moves directly above the lower glass plate 13, the electric telescopic rod 10 pushes the upper glass plate 12 to fit with the lower glass plate 13. At the same time, the first adsorption plate 9 releases its adsorption on the upper glass plate 12, and the upper glass plate 12 and the lower glass plate 13 are placed in the heating furnace. The low melting point glass powder is heated to melt it, and after cooling, a sealing frame is formed. A vacuum pump is connected to the vacuum hole through a pre-reserved air extraction hole on the sealing frame. The vacuum pump is started to extract the air in the chamber. After the vacuum degree reaches the standard, the air extraction hole is heat-sealed to completely isolate the outside air.
