Description

A high-precision tempered glass curved surface forming equipment Technical Field

[0001] This invention relates to the field of glass production equipment technology, specifically to a high-precision tempered glass curved surface forming equipment. Background Technology

[0002] This invention is an improved design based on the technical solution of an automotive glass tempering forming mechanism (publication number CN111003930B), aiming to solve the problems existing in the current production process. An automotive glass tempering forming mechanism includes a bending mechanism, a conveying mechanism, an air grille mechanism, and a body. By fixing the first upper air knife and the first lower air knife to ensure relative airflow, the surface accuracy of the tempered glass after forming can be effectively guaranteed.

[0003] However, in actual production, it was found that after the glass is heated from the furnace, it is in a high-temperature softened state. At this time, the hardness of the glass surface is the lowest. When it is conveyed between the first upper air knife and the first lower air knife, the direction of the cold air is directly facing the surface of the glass. Affected by the wind pressure, the softened glass surface is prone to dents, which greatly affects the forming accuracy of the glass curved surface.

[0004] Therefore, in order to solve the above problems, a high-precision tempered glass curved surface forming device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision tempered glass curved surface forming equipment, which solves the problem that when heated and softened glass is directly blown by cold air, the wind pressure will cause indentations on the glass curved surface, thereby reducing the accuracy of the glass curved surface.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-precision tempered glass curved surface forming device includes a machine body, a first roller conveyor and a second roller conveyor disposed inside the machine body, and an air inlet channel, a flexible shaft, a fixed rod, a drive unit, an air outlet channel, a movable component, and a baffle component. Both the first and second roller conveyors include multiple sets of T-shaped blocks connected in sequence. The air inlet channel is connected to the T-shaped blocks, the fixed rod passes through the T-shaped blocks, the drive unit is disposed on the fixed rod and connected to the flexible shaft, the T-shaped blocks are hollow and have openings at their ends, the air outlet channel is disposed within the T-shaped blocks, and the movable component is sleeved on the air outlet channel and connected to the drive unit. When the air outlet channel is in a neutral position, the glass is perpendicular to the central axis of the air outlet channel. When the flexible shaft drives the glass to move forward or backward, the drive unit, through the movable component, causes the air outlet channel to deviate from the neutral position in the direction of glass movement. The baffle component is disposed within the air outlet channel. When the air outlet channel deviates from the neutral position in the direction of glass movement, the baffle component rotates and increases the blocking area at the end of the air outlet channel.

[0008] Preferably, the drive unit includes a fixing component, a mounting plate, a roller, a rack, a U-shaped component, a first pin, and a second pin. The fixing component is mounted on a fixing rod, the mounting plate is mounted on the fixing component, the roller is mounted inside the mounting plate, the flexible shaft passes through the mounting plate and the roller, the surface of the roller is provided with an annular toothed groove, the rack passes through the T-block and the mounting plate and meshes with the annular toothed groove, the U-shaped component is mounted on the rack, the movable component is rotatably mounted on the U-shaped component via the first pin, and the second pin is mounted inside the T-block, with its two ends respectively rotatably connected to the air outlet channel and the T-block.

[0009] It is known that to ensure the forming accuracy of curved glass surfaces, the air pressure needs to be reduced to avoid excessive air pressure causing indentations on the glass surface. However, reducing the air pressure will affect the cooling rate of the glass, thereby reducing the forming efficiency of curved glass surfaces. Therefore, this solution is adopted. When the flexible shaft drives the glass to move between the first and second roller tracks through the rollers, the meshing connection between the annular toothed groove and the rack can be used to drive the rack and glass to move in opposite directions. Under the action of pins one and two, the air outlet channel is driven to swing, so that the cold air blown out from the end of the air outlet channel is tilted towards the glass surface in the direction of glass movement. This avoids the cold air blowing directly and affecting the forming accuracy of the curved glass surface. At the same time, it can increase the air pressure, increase the flow rate of the cold air, accelerate the heat dissipation of the glass surface, and thus ensure the forming efficiency.

[0010] Preferably, the air outlet channel includes a connected injector, a circular tube, and a flexible hose. The flexible hose extends into the interior of the air inlet channel. The movable component and the second pin are both connected to the circular tube. The baffle assembly includes a baffle plate, a rotating rod, a T-shaped rod, and an L-shaped rod. The injector has an external air hood. The baffle plate is coaxially disposed inside the injector and has an internal air hood on its surface. The rotating rod passes through the baffle plate and is connected to the injector. The rotating rod has a spiral groove in its wall. The circular tube has a side opening in its side wall. The T-shaped rod is disposed inside the circular tube and passes through the side opening to connect to the movable component. One end of the L-shaped rod is disposed on the T-shaped rod, and the other end is slidably disposed inside the spiral groove.

[0011] By adopting the above scheme, the baffle plate can be driven to rotate around the axis of the air outlet channel as the air outlet channel deviates from the neutral position towards the direction of glass movement. This causes the outer air hood and the inner air outlet hood to be misaligned, thereby reducing the exposed area of ​​the outer air hood. This further increases the wind pressure and wind speed of the cold air when it is blown out from the outer air hood. When the air outlet channel is in the neutral position, the outer air hood is directly opposite the inner air outlet hood, at which point the wind pressure is the minimum. This achieves dynamic adjustment of the cold air pressure, further ensuring the forming accuracy and forming efficiency of the glass curved surface.

[0012] Preferably, the flow-blocking assembly further includes a spring, which is disposed inside the circular tube, and the two ends of the spring are respectively connected to the T-shaped rod and the circular tube.

[0013] By adopting the above scheme, the elastic force generated when the spring deforms can pull the rack back to its original position, so that the teeth at the end of the annular groove and the rack can re-mesh after being misaligned. Then, during the continuous unidirectional rotation of the roller, the elastic force of the spring can drive the rack to move back and forth in a small amplitude, so that the injector can swing back and forth in a small amplitude around the second pin as the rotation axis. The baffle can swing back and forth in a small amplitude around the axis of the air outlet channel, thereby continuously adjusting the direction and pressure of the cold air in a small amplitude, expanding the blowing range of the cold air, and thus ensuring the forming accuracy and forming efficiency of the glass curved surface.

[0014] Preferably, the outgoing air hood and the inner air hood are the same, and the radial cross-sectional area of ​​the inner ring of the hose is equal to the area of ​​the outgoing air hood.

[0015] By adopting the above scheme, when the air outlet channel is in a neutral position, the air pressure entering the hose is approximately the same as the air pressure blown out from the outer fan hood. When the air outlet channel deviates from the neutral position, it can increase the air pressure when the cold air is blown out from the outer fan hood, ensuring the cooling effect while avoiding the formation of dents on the glass surface, thus effectively ensuring the forming accuracy of the glass surface.

[0016] Preferably, the number of spiral turns of the spiral groove is between 0 and 0.25.

[0017] By adopting the above solution, during the process of the T-shaped rod driving the L-shaped rod to move inside the spiral groove, it is possible to avoid the situation where the baffle rotates too much and the outgoing air cover is completely blocked by the baffle. This ensures that the cold air is blown out normally during the rotation of the baffle, thus ensuring the normal operation of the glass cooling process.

[0018] Preferably, the movable component includes an outer tube, a connecting tube, and a connecting ring plate, wherein the outer tube, the connecting tube, and the connecting ring plate are connected in sequence and are all sleeved with the round tube, and the first pin and the T-shaped rod are both connected to the outer tube.

[0019] By adopting the above scheme, while ensuring that the outer tube can drive the T-shaped rod to move along the axial direction of the round tube, the sealing treatment of the round tube wall is achieved, so that the cold air can be blown out smoothly from the outgoing air hood opened on the surface of the ejector, avoiding air leakage and unstable air pressure, thereby further ensuring the forming accuracy of the glass curved surface.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. Through the configured drive unit, baffle assembly, baffle plate, and air outlet channel, the direction of the cold air can be continuously adjusted during the process of the flexible shaft driving the glass to reciprocate between the first and second roller tracks. This ensures that the direction of the cold air is tilted towards the direction of glass movement. Furthermore, during the process of the flexible shaft adjusting the direction of glass movement through the rollers, when the central axis of the air outlet channel is perpendicular to the glass surface, the air pressure of the cold air blowing out from the end of the air outlet channel can be reduced to a minimum. When the glass moves in a single direction, the air outlet channel can maintain an inclined angle. This not only prevents the cold air from blowing directly onto the glass when it blows out from the end of the air outlet channel, thus avoiding affecting the forming accuracy of the glass surface, but also ensures the forming efficiency of the glass surface.

[0022] 2. By using a rack and spring, when the gear rotates and drives the rack to its limit position via the annular tooth groove, the spring provides a restoring force to the rack. That is, after the teeth at the end of the rack are misaligned with the annular tooth groove, the restoring force provided by the spring can drive the teeth to re-mesh with the annular tooth groove. This allows the roller to continue driving the rack to move during rotation. As the roller rotates in one direction, the rack can first move in one direction and then perform a small-amplitude reciprocating motion. In other words, the air outlet channel can swing back and forth around the second pin as a rotation axis while the rack is performing a small-amplitude reciprocating motion, thereby continuously adjusting the direction of the cold air. This prevents the cold air from blowing on the glass surface at a fixed angle, reduces the wind pressure, and expands the blowing range of the cold air, further ensuring the forming accuracy and efficiency of the glass curved surface.

[0023] 3. Through the design of the T-shaped rod, L-shaped rod, and rotating rod, during the small-amplitude reciprocating motion of the rack, the connection between the T-shaped rod and the L-shaped rod drives the L-shaped rod to reciprocate along the axis of the air outlet channel. The sliding connection between the L-shaped rod and the spiral groove on the rotating rod drives the rotating rod to move the baffle plate in a small-amplitude reciprocating motion around the axis of the air outlet channel. This achieves the effect of continuously adjusting the size of the exhaust hood with small amplitudes. Specifically, as the air outlet channel swings and approaches the neutral position, the baffle plate increases the area of ​​the exhaust hood (i.e., reduces the air pressure when cold air is blown out of the exhaust hood). Conversely, as the air outlet channel swings and deviates from the neutral position, the baffle plate reduces the area of ​​the exhaust hood (i.e., increases the air pressure when cold air is blown out of the exhaust hood). This dynamic adjustment of the exhaust hood area avoids the problem of increased air pressure affecting the glass surface forming accuracy during the swing of the air outlet channel towards the neutral position.

[0043] 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.

[0044] Please refer to Figures 1 to 8. This invention provides a high-precision tempered glass curved surface forming device, the technical solution of which is as follows:

[0045] Specifically, referring to Figures 1, 2, 3, 4, and 5, a high-precision tempered glass curved surface forming device includes a machine body 1, a first roller conveyor 2 and a second roller conveyor 3 disposed inside the machine body 1, and also includes an air inlet channel 4, a flexible shaft 5, a fixing rod 6, a drive unit 7, an air outlet channel 8, a movable component 9, and a baffle component 10. Both the first roller conveyor 2 and the second roller conveyor 3 include multiple sets of T-shaped blocks 21 connected in sequence. The air inlet channel 4 is connected to the T-shaped blocks 21, and the fixing rod 6 is disposed through the T-shaped blocks 21. The drive unit 7 is mounted on the fixed rod 6 and connected to the flexible shaft 5. The T-shaped block 21 is hollow and has an opening slot 211 at its end. The air outlet channel 8 is located inside the T-shaped block 21. The movable component 9 is fitted onto the air outlet channel 8 and connected to the drive unit 7. When the air outlet channel 8 is in the neutral position, the glass 11 is perpendicular to the central axis of the air outlet channel 8. When the flexible shaft 5 drives the glass 11 to move forward or backward, the drive unit 7 drives the air outlet channel 8 to deviate from the neutral position in the direction of movement of the glass 11 through the movable component 9.

[0046] The drive unit 7 includes a fixing member 71, a mounting plate 72, a roller 73, a rack 74, a U-shaped member 75, a first pin 76, and a second pin 77. The fixing member 71 is mounted on the fixing rod 6, the mounting plate 72 is mounted on the fixing member 71, the roller 73 is mounted inside the mounting plate 72, the flexible shaft 5 passes through the mounting plate 72 and the roller 73, the surface of the roller 73 is provided with an annular toothed groove 731, the rack 74 passes through the T-shaped block 21 and the mounting plate 72 and meshes with the annular toothed groove 731, the U-shaped member 75 is mounted on the rack 74, the movable component 9 is rotatably mounted on the U-shaped member 75 through the first pin 76, and the second pin 77 is mounted inside the T-shaped block 21, with both ends rotatably connected to the air outlet channel 8 and the T-shaped block 21 respectively.

[0047] Under the above-mentioned conditions, during the process of the flexible shaft 5 driving the glass 11 to move through the roller 73, the annular toothed groove 731 set on the roller 73 can drive the rack 74 to move through meshing with the rack 74, and the direction of movement of the rack 74 is opposite to the direction of movement of the glass 11. During the movement, the rack 74 can drive the U-shaped part 75 to move. During the movement of the U-shaped part 75, it can drive the movable component 9 to move through the first pin 76. During the movement of the movable component 9, it can use the connection between the second pin 77 and the air outlet channel 8 and the T-shaped block 21 to drive the air outlet channel 8 to deviate from the neutral position, so that when the cold air is blown out from the air outlet channel 8, it tilts towards the side of the glass 11's movement direction, avoiding the situation where the curved surface of the glass 11 will have an indentation due to wind pressure when the cold air blows directly onto the glass 11, effectively ensuring the forming accuracy of the curved surface of the glass 11.

[0048] As one embodiment of the present invention, referring to Figures 1, 5, and 6, the baffle assembly 10 is disposed within the air outlet channel 8. When the air outlet channel 8 deviates from its neutral position towards the direction of movement of the glass 11, the baffle assembly 10 rotates and increases the blocking area at the end of the air outlet channel 8. The air outlet channel 8 includes a connected injector 81, a circular tube 82, and a flexible hose 83. The flexible hose 83 extends into the interior of the air inlet channel 4. The movable assembly 9 and the second pin 77 are both connected to the circular tube 82. The baffle assembly 10 includes a baffle plate 101, a rotating rod 102, a T-shaped rod 103, and an L-shaped rod 104. An external air hood 811 is provided on the injector 81. The baffle plate 101 is coaxially disposed within the injector 81 and has an internal air hood 1011 on its surface. The rotating rod 102 passes through the baffle plate 101 and is connected to the injector 81. A spiral groove 1021 is provided on the rod wall of the rotating rod 102, and the number of spiral turns of the spiral groove 1021 is between 0 and 0.25 turns. When the L-shaped rod 104 is at the uppermost position of the spiral groove 1021, the outer air hood 811 is directly opposite the inner air hood 1011. When the L-shaped rod 104 moves away from the baffle plate 101 along the axis of the rotating rod 102 inside the spiral groove 1021, the rotating rod 102 will drive the baffle plate 101 to rotate. As can be seen from Figures 4 and 5, both the outer air hood 811 and the inner air hood 1011 are provided with two sets. When the rotating rod 102 rotates 0.2... When there are 5 turns, or a quarter turn, the outward air hood 811 will be completely misaligned with the inner air hood 1011, resulting in the inability to blow out cold air, which will affect the normal progress of the cooling process. The side wall of the round tube 82 has a side opening 821. The T-shaped rod 103 is set inside the round tube 82 and passes through the side opening 821 to connect with the movable component 9. One end of the L-shaped rod 104 is set on the T-shaped rod 103, and the other end is slidably set inside the spiral groove 1021.

[0049] Under the above-mentioned conditions, when the rack 74 drives the outer tube 91 away from the second pin 77 along the axis of the circular tube 82 via the U-shaped part 75 and the first pin 76, the outer tube 91 can drive the T-shaped rod 103 to move. During the movement of the T-shaped rod 103, it can drive the L-shaped rod 104 to move. Since the rod wall of the rotating rod 102 has a spiral groove 1021, and one end of the L-shaped rod 104 is slidably disposed inside the spiral groove 1021, and the second pin 77 is disposed between the first pin 76 and the injector 81, the free end of the L-shaped rod 104 can move inside the spiral groove 1021 and away from the injector 81. During this process, the L-shaped rod 104 presses against the side wall of the spiral groove 1021 and drives the rotating rod 102 to rotate. During the rotation of the rotating rod 102, it drives the baffle plate 101 to rotate. During the rotation of the baffle plate 101, the outgoing air hood 811 and the inner air hood 102 are moved away from each other. The baffle plate 101 gradually shifts to a staggered position, gradually blocking the exhaust hood 811, thereby reducing the exposed area of ​​the exhaust hood 811. This passively increases the air pressure when the cold air is blown out from the exhaust hood 811 (at which time the ejector 81 is tilted towards the direction of glass 11 movement). This prevents the cold air from blowing directly onto the curved surface of glass 11 while increasing the air velocity, ensuring both the forming accuracy and efficiency of the curved surface of glass 11. At the same time, by setting the number of spiral turns of the spiral groove 1021, the baffle plate 101 is prevented from rotating too much during the movement of the L-shaped rod 104 driven by the T-shaped rod 103 within the spiral groove 1021, thus preventing the exhaust hood 811 from being completely blocked by the baffle plate 101. This ensures that the cold air is blown out normally during the rotation of the baffle plate 101, thereby ensuring the normal cooling process of glass 11.

[0050] As one embodiment of the present invention, referring to Figures 1, 5 and 8, the flow-blocking assembly 10 further includes a spring 105, which is disposed inside the circular tube 82, and the two ends of the spring 105 are respectively connected to the T-shaped rod 103 and the circular tube 82.

[0051] Under the above-mentioned conditions, since the spring 105 is in a deformed state when the circular tube 82 deviates from the neutral position, and during the continuous rotation of the roller 73, when the teeth at the end position of the rack 74 are misaligned with the annular groove 731, the elastic force of the spring 105 drives the teeth to re-mesh with the annular groove 731. Thus, during the continuous unidirectional rotation of the roller 73, the rack 74 can move back and forth slightly, that is, the baffle 101 can swing back and forth slightly. This allows for continuous adjustment of the area blocked by the baffle 101 of the outlet hood 811, realizing dynamic adjustment of the cold air pressure and blowing range blown out from the outlet hood 811. This effectively expands the cooling effect on the glass 11 and further ensures the forming accuracy and forming efficiency of the curved surface of the glass 11.

[0052] As one embodiment of the present invention, referring to Figures 1, 5, 6, 7 and 8, the outer air hood 811 and the inner air hood 1011 are the same. The radial cross-sectional area of ​​the inner ring of the flexible hose 83 is equal to the area of ​​the outer air hood 811. When the air outlet channel 8 is in the neutral position, the air pressure entering the flexible hose 83 is approximately the same as the air pressure blown out from the outer air hood 811. When the air outlet channel 8 deviates from the neutral position, it can increase the air pressure when cold air is blown out from the outer air hood 811, ensuring the cooling effect while avoiding the occurrence of concave marks on the curved surface of the glass 11, effectively ensuring the forming accuracy of the curved surface of the glass 11.

[0053] As one embodiment of the present invention, referring to Figures 1 and 5, the movable component 9 includes an outer tube 91, a connecting tube 92, and a connecting ring plate 93. The outer tube 91, the connecting tube 92, and the connecting ring plate 93 are connected in sequence and are all sleeved with the round tube 82. The first pin 76 and the T-shaped rod 103 are both connected to the outer tube 91.

[0054] By adopting the above scheme, while ensuring that the outer tube 91 can drive the T-shaped rod 103 to move along the axial direction of the round tube 82, the sealing treatment of the tube wall of the round tube 82 is achieved, so that the cold air can be blown out smoothly from the outgoing air hood 811 opened on the surface of the injector 81, avoiding air leakage and unstable air pressure, thereby further ensuring the forming accuracy of the curved surface of the glass 11.

[0055] Working Principle: To prevent cold air from blowing directly onto the curved surface and causing indentations during the cooling process of glass 11, referring to Figures 1, 3, and 5, the drive unit 7 can adjust the angle of the air outlet channel 8 using rollers 73 during the movement of glass 11. This allows the cold air to be blown out at an angle in the direction of glass 11's movement, preventing the cold air from blowing directly onto the curved surface of glass 11 and causing indentations, thus effectively ensuring the forming accuracy of the curved surface of glass 11. To reduce the wind pressure on the curved surface of glass 11 when the ejector 81 is in a neutral position during the adjustment of the glass 11's movement direction by rollers 73, referring to Figures 1, 5, and 6, the baffle assembly 10 can dynamically adjust the exposed area of ​​the outer air hood 811. This ensures that the wind pressure of the cold air blown out by the ejector 81 is at its minimum when it is in a neutral position, while gradually increasing as the ejector 81 deviates from the neutral position. This ensures both the forming accuracy and forming efficiency of the curved surface of glass 11.

[0056] Specifically: After the heated and softened glass 11 is conveyed between the first roller conveyor 2 and the second roller conveyor 3, the curvature of the first roller conveyor 2 and the second roller conveyor 3 is adjusted so that the first roller conveyor 2 and the second roller conveyor 3 are kept coaxial and the roller 73 is driven to rotate by the flexible shaft 5.

[0057] Because the annular groove 731 on the roller 73 meshes with the rack 74, when the roller 73 drives the glass 11 to move, the annular groove 731 can drive the rack 74 to move in the opposite direction to the movement of the glass 11 (since the surface of the glass 11 is in contact with the surface of the roller 73 and moves by relying on the friction of the roller 73 surface, its movement direction is opposite to the rotation direction of the roller 73). During the movement, the rack 74 can drive the U-shaped part 75 to move. During the movement of the U-shaped part 75, the outer tube 91 can be moved horizontally through the first pin 76. The outer tube 91 is sleeved with the round tube 82, and the round tube 82 is rotatably connected to the T-block 21 through the second pin 77. During the horizontal movement of the outer tube 91, it can move away from the ejector 81 along the axis of the round tube 82, and at the same time drive the ejector 81 to follow the round tube 82 to rotate in the direction of the glass 11 with the second pin 77 as the rotation axis, until the teeth of the annular groove 731 and the upper end of the rack 74 are misaligned, so as to avoid the outer air cover 811 on the ejector 81 facing the surface of the glass 11. This ensures the forming accuracy of the curved surface of the glass 11 while also ensuring the forming efficiency.

[0058] Since the T-shaped rod 103 passes through the side opening 821 and is connected to the outer tube 91, when the outer tube 91 moves away from the injector 81 along the axial direction of the circular tube 82, the T-shaped rod 103 will drive the L-shaped rod 104 to move. Because one end of the L-shaped rod 104 is slidably disposed within the spiral groove 1021 on the rotating rod 102, the L-shaped rod 104 can compress the side wall of the spiral groove 1021 and drive the rotating rod 102 to rotate as it moves along with the T-shaped rod 103. During the rotation of the rotating rod 102, it drives the baffle plate 101 to rotate, causing the baffle plate 101 to rotate. The inner air outlet hood 1011 on the 1 is misaligned with the outer air outlet hood 811 on the ejector 81, so that the baffle 101 blocks the outer air outlet hood 811. The larger the rotation angle of the ejector 81, the larger the blocking range of the outer air outlet hood 811, that is, the smaller the exposed range of the outer air outlet hood 811. Since the flow rate of cold air delivered to the air outlet channel 8 through the air inlet channel 4 remains unchanged per unit time, the pressure and flow rate of the cold air when it flows out of the outer air outlet hood 811 are increased, which ensures the forming accuracy and forming efficiency of the curved surface of the glass 11.

[0059] During the cooling process of glass 11 forming, it is driven by roller 73 to move back and forth between the first roller track 2 and the second roller track 3. When glass 11 moves to the position directly opposite the ejector 81, the round tube 82 and the ejector 81 are in a neutral position. At this time, the T-shaped rod 103 and the L-shaped rod 104 are in their original positions, that is, the position of the outgoing air hood 811 directly opposite the inner air hood 1011. The outgoing air hood 811 is in the most exposed state. The pressure and flow rate of the cold air when it blows onto the glass 11 are the minimum, which can effectively avoid the deformation of the curved surface of glass 11 and further ensure the forming accuracy of the curved surface of glass 11.
