Description

TECHNICAL FIELD

[0001] The utility model relates to liquid crystal substrate glass manufacturing equipment technical field especially relates to a glass substrate traction device. BACKGROUND

[0002] At present, domestic liquid crystal glass substrate mainly uses the overflow down-draw method to produce, wherein the long roll plays a very key role in the forming process immersion and emergency, the long roll usually penetrates the furnace cavity, and the high-temperature resistant boss working surface is slightly wider than the glass strip, which is used to clamp and pull the unstable glass strip in the forming immersion and emergency, so that the down-drawn glass strip tends to be stable, and then the substrate glass meeting the product quality is formed.

[0003] The long roll is usually arranged in pairs, and one aligning ball bearing is arranged at the head and tail of the same side long roll to realize the rotation and limiting of the long roll. The two long rolls rotate towards each other. In normal production, the two long rolls are in an open state, and the glass strip normally flows down between the two long rolls. When immersed and in an emergency, the two long rolls are close to each other, clamp the unstable glass strip in the process state and rotate, so that the down-drawn glass strip tends to be stable.

[0004] The two ends of each long roll are respectively supported by a floating bearing seat to realize the rotation and opening and clamping action of the long roll. In the existing production technology, the opening and closing of the long roll mainly rely on four operators standing at the four supporting points of the two long rolls. When opening and closing is needed, the personnel manually open or close the long roll after receiving the instruction. However, the consistency of the opening and closing action of the long roll cannot be guaranteed in this process, and some human factors may cause the long roll to open or close not in time, resulting in a large production accident.

DETAILED DESCRIPTION

[0030] 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.

[0031] like Figures 1-4 As shown, this embodiment provides a glass substrate pulling device, including:

[0032] Furnace body 1, inside which are provided a first roller 6 and a second roller 7, the first roller 6 and the second roller 7 are arranged in parallel;

[0033] The first guide assembly is mounted on the furnace body 1 and connected to both ends of the first roller body 6;

[0034] The second guide assembly is installed on the furnace body 1 and connected to both ends of the second roller body 7;

[0035] A first drive assembly is mounted on the furnace body 1 and connected to a first guide assembly;

[0036] The second drive assembly is mounted on the furnace body 1 and connected to the second guide assembly;

[0037] The first drive assembly and the second drive assembly respectively drive the first guide assembly and the second guide assembly to move, so that the first roller 6 and the second roller 7 move towards each other or away from each other along an axis perpendicular to the first roller 6.

[0038] Overall, under normal production conditions, there is a gap between the first roller 6 and the second roller 7. The glass substrate flows down through the gap between the first roller 6 and the second roller 7. In order to clamp and pull the glass substrate with unstable process conditions and make the pulled glass substrate tend to be stable, the first driving component and the second driving component drive the first guiding component and the second guiding component to move, so that the first roller 6 and the second roller 7 can move towards each other along the axial direction of the first roller 6. This makes the gap between the first roller 6 and the second roller 7 adapt to the thickness of the glass substrate, thereby reducing the downward speed of the glass substrate and making the downward speed of the pulled glass substrate tend to be stable.

[0039] Compared with existing technologies, by using the first drive assembly and the second drive assembly to activate the first guide assembly and the second guide assembly, the consistency of the first roller 6 and the second roller 7 during their relative movement along the axial direction perpendicular to the first roller 6 can be ensured. This avoids deviations at the ends of the first roller 6 and the second roller 7 during adjustment. By ensuring the consistency of the first roller 6 and the second roller 7 during adjustment, the stability of the glass substrate during its downward movement can be effectively improved, as can the production efficiency of the glass substrate. Furthermore, through the cooperation between the mechanical structures, production accidents caused by human factors can be avoided, thus improving the overall safety of the device.

[0040] like Figures 1-2 As shown, in this embodiment, the first guide assembly includes a first lower swing arm 8, a first counterweight arm 10, a first upper swing arm 12, a third lower swing arm, a third counterweight arm 22, a third upper swing arm, a first bearing seat 4, and a third bearing seat. The first lower swing arm 8 and the first upper swing arm 12 are hinged to the furnace body 1. The two ends of the first counterweight arm 10 are respectively hinged to the first lower swing arm 8 and the first upper swing arm 12. The end of the first lower swing arm 8 away from the first counterweight arm 10 is connected to the first bearing seat 4. The third lower swing arm and the third upper swing arm are hinged to the furnace body 1. The two ends of the third counterweight arm 22 are respectively hinged to the third lower swing arm and the third upper swing arm. The end of the third lower swing arm away from the third counterweight arm 22 is connected to the third bearing seat. The two ends of the first roller body 6 are coaxially arranged with the first bearing seat 4 and the third bearing seat, respectively.

[0041] The second guide assembly includes a second lower swing arm 9, a second counterweight arm 11, a second upper swing arm 13, a fourth lower swing arm, a fourth counterweight arm, a fourth upper swing arm, a second bearing seat 5, and a fourth bearing seat. The second lower swing arm 9 and the second upper swing arm 13 are hinged to the furnace body 1. The two ends of the second counterweight arm 11 are respectively hinged to the second lower swing arm 9 and the second upper swing arm 13. The end of the second lower swing arm 9 away from the second counterweight arm 11 is connected to the second bearing seat 5. The fourth lower swing arm and the fourth upper swing arm are hinged to the furnace body 1. The two ends of the fourth counterweight arm are respectively hinged to the fourth lower swing arm and the fourth upper swing arm. The end of the fourth lower swing arm away from the third counterweight arm 22 is connected to the fourth bearing seat. The two ends of the second roller body 7 are coaxially arranged with the second bearing seat 5 and the fourth bearing seat, respectively.

[0042] Specifically, when the first drive assembly drives the first guide assembly to move, at one end of the first roller body 6, the first upper swing arm 12 rotates around the hinge axis, and through the first counterweight arm 10, it can be linked to rotate the first lower swing arm 8 around the hinge axis. At the other end of the first roller body 6, the third upper swing arm rotates around the hinge axis, and through the third counterweight arm 22, it can be linked to rotate the third lower swing arm around the hinge axis, which can cause the first roller body 6 to move closer to or further away from the second roller body 7 along an axis perpendicular to the first roller body 6. When the second drive assembly drives the second guide assembly to move, at one end of the second roller body 7, the second upper swing arm... 13 rotates around the hinge axis, and through the second counterweight arm 11, it can link the second lower swing arm 9 to rotate around the hinge axis. At the other end of the second roller body 7, the fourth upper swing arm rotates around the hinge axis, and through the fourth counterweight arm, it can link the fourth lower swing arm to rotate around the hinge axis. This allows the second roller body 7 to move closer to or further away from the first roller body 6 along an axis perpendicular to the first roller body 6, ultimately reducing or increasing the gap between the first roller body 6 and the second roller body 7, so that the size of the gap is adapted to the thickness of the glass substrate, thereby reducing the downward speed of the glass substrate and making the downward speed of the pulled glass substrate tend to be stable.

[0043] like Figure 1 and Figure 3 As shown, in this embodiment, the first drive assembly includes a first motor, a first gear 3, a first rack 17, a third rack 18, a first wire rope 15, and a third wire rope 19. The first motor is installed inside the first housing 2 on the furnace body 1 and is connected to the first gear 3. The first rack 17 and the third rack 18 are both slidably installed on the first housing 2. The extension directions of the first rack 17 and the third rack 18 are both consistent with the axial direction of the first roller 6 and are both meshed with the first gear 3. One end of the first wire rope 15 is connected to the first rack 17, and the other end of the first wire rope 15 passes through the first fixed pulley group and is connected to the first upper swing arm 12. One end of the third wire rope 19 is connected to the third rack 18, and the other end of the third wire rope 19 passes through the third fixed pulley group and is connected to the third upper swing arm.

[0044] The second drive assembly includes a second motor, a second gear, a second rack, a fourth rack, a second wire rope 16, and a fourth wire rope. The second motor is installed in the second housing on the furnace body 1 and is connected to the second gear. The second rack and the fourth rack are slidably installed on the second housing. The extension directions of the second rack and the fourth rack are consistent with the axial direction of the second roller 7 and are both meshed with the second gear. One end of the second wire rope 16 is connected to the second rack, and the other end of the second wire rope 16 passes through the second fixed pulley group and is connected to the second upper swing arm 13. One end of the fourth wire rope is connected to the fourth rack, and the other end of the fourth wire rope passes through the fourth fixed pulley group and is connected to the fourth upper swing arm.

[0045] Specifically, when the first drive assembly drives the first guide assembly, the first motor drives the first gear 3 to rotate. Since the first gear 3 meshes with both the first rack 17 and the third rack 18, it can drive the first rack 17 and the third rack 18 to move towards each other along the axial direction of the first roller body 6. Furthermore, the first wire rope 15 and the third wire rope 19 respectively cause the first upper swing arm 12 to rotate around its hinge axis and the third upper swing arm to rotate around its hinge axis, thereby causing the first roller body 6 to move closer to or further away from the second roller body 7 along an axial direction perpendicular to the first roller body 6. When the second drive assembly drives the second guide assembly, the second motor drives the second gear... The rotation, since the second gear meshes with both the second and fourth racks, can drive the second and fourth racks to move towards each other along the axial direction of the second roller 7. Furthermore, the second upper swing arm 13 and the fourth upper swing arm rotate around their hinge axes respectively via the second and fourth steel wire ropes 16 and 16, so that the second roller 7 moves closer to or further away from the first roller 6 along an axial direction perpendicular to the first roller 6. Ultimately, this reduces or increases the gap between the first roller 6 and the second roller 7, making the gap size suitable for the thickness of the glass substrate, thereby reducing the downward speed of the glass substrate and stabilizing the downward speed of the pulled glass substrate.

[0046] like Figures 1-2 As shown, in this embodiment, the first lower swing arm 8, the first upper swing arm 12, the third lower swing arm, and the third upper swing arm are arranged in parallel pairs; the second lower swing arm 9, the second upper swing arm 13, the fourth lower swing arm, and the fourth upper swing arm are arranged in parallel pairs; and the first counterweight arm 10, the second counterweight arm 11, the third counterweight arm 22, and the fourth counterweight arm are arranged vertically and in parallel pairs.

[0047] Specifically, when the first drive component and the second drive component drive the first guide component and the second guide component to move respectively, by achieving the parallel arrangement of the first lower swing arm 8, the first upper swing arm 12, the third lower swing arm, and the third upper swing arm in pairs, and the parallel arrangement of the second lower swing arm 9, the second upper swing arm 13, the fourth lower swing arm, and the fourth upper swing arm in pairs, the consistency of kinetic energy transmission can be ensured. In addition, the first counterweight arm 10, the second counterweight arm 11, the third counterweight arm 22, and the fourth counterweight arm are arranged vertically and in parallel arrangement in pairs, which can ensure the stability of the first counterweight arm 10, the second counterweight arm 11, the third counterweight arm 22, and the fourth counterweight arm in the power transmission process, optimize the gravity transmission path, and improve the overall balance of the first guide component and the second guide component.

[0048] like Figure 2 As shown, in this embodiment, a first plate and a second plate 101 are also included. The first plate and the second plate 101 are fixed relative to the furnace body 1. A first guide groove is provided on the first plate, and a second guide groove 102 is provided on the second plate 101. The two ends of the first roller 6 pass through the first guide groove, and the two ends of the second roller 7 pass through the second guide groove 102.

[0049] Specifically, the two ends of the first roller 6 pass through the first guide grooves on the two end first plates and are connected to the first bearing seat 4 and the third bearing seat, respectively. The two ends of the second roller 7 pass through the second guide grooves 102 on the two end second plates 101 and are connected to the second bearing seat 5 and the fourth bearing seat, respectively. When the first lower swing arm 8 and the third lower swing arm rotate around the hinge point, the two ends of the first roller 6 move along the path of the first guide groove. When the second lower swing arm 9 and the fourth lower swing arm rotate around the hinge point, the two ends of the second roller 7 move along the path of the second guide groove 102. By setting the first guide groove and the second guide groove 102, the stability of the first roller 6 and the second roller 7 during the gap adjustment process can be further improved.

[0050] like Figures 1-2 As shown, in this embodiment, a first communicating vessel schematic tube 14 and a second communicating vessel schematic tube are also included. The first communicating vessel schematic tube 14 is installed on one side of the furnace body 1 located in the first housing 2. When the first counterweight arm 10 and the third counterweight arm 22 move synchronously, the pointers on the first counterweight arm 10 and the third counterweight arm 22 move along the vertical sections on both sides of the first communicating vessel schematic tube 14. The second communicating vessel schematic tube is installed on one side of the furnace body 1 located in the second housing. When the second counterweight arm 11 and the fourth counterweight arm move synchronously, the pointers on the second counterweight arm 11 and the fourth counterweight arm move along the vertical sections on both sides of the second communicating vessel schematic tube.

[0051] Specifically, it also includes a first communicating vessel indicator tube 14 and a second communicating vessel indicator tube. When the first driving component drives the first upper swing arm 12 to rotate around its hinge axis and the third upper swing arm to rotate around its hinge axis, the pointers on the first counterweight arm 10 and the third counterweight arm 22 move along the vertical sections on both sides of the first communicating vessel indicator tube 14. When the second driving component drives the second upper swing arm 13 to rotate around its hinge axis and the fourth upper swing arm to rotate around its hinge axis, the pointers on the second counterweight arm 11 and the fourth counterweight arm move along the vertical sections on both sides of the second communicating vessel indicator tube. By reading the pointer positions of the first communicating vessel indicator tube 14 and the second communicating vessel indicator tube, the difference in the rotation angles of the first roller 6 and the second roller 7 can be adjusted to make the adjustment degrees of the first roller 6 and the second roller 7 consistent, which can effectively improve the stability of the glass substrate during the pull-down process.

[0052] like Figures 3-4As shown, in this embodiment, a first adjusting member 20, a second adjusting member, a third adjusting member 21, and a fourth adjusting member are also included. The first adjusting member 20 is mounted on the first rack 17 and connected to the end of the first wire rope 15 away from the first upper swing arm 12. The second adjusting member is mounted on the second rack and connected to the end of the second wire rope 16 away from the second upper swing arm 13. The third adjusting member 21 is mounted on the third rack 18 and connected to the end of the third wire rope 19 away from the third upper swing arm. The fourth adjusting member is mounted on the fourth rack and connected to the end of the fourth wire rope away from the fourth upper swing arm.

[0053] Specifically, the first rack 17 is provided with a first adjusting member 20, the second rack is provided with a second adjusting member, the third rack 18 is provided with a third adjusting member 21, and the fourth rack is provided with a fourth adjusting member. By rotating the first lead screw 2001 of the first adjusting member 20, the first rod body 2002, which is coaxially arranged with the first lead screw 2001, can be driven to move along its axial direction. By changing the position of the first lead screw 2001 and the first rod body 2002 relative to the first rack 17, the first roller body 6 at one end of the first bearing seat 4 can be finely adjusted. By adjusting the third lead screw 2101 of the third adjusting member 21, the first roller body 6 at one end of the first bearing seat 4 can be driven to move along its axial direction. The third rod 2102, coaxially arranged, moves along its axial direction. By changing the position of the third lead screw 2101 and the third rod 2102 relative to the third rack 18, the first roller 6 at one end of the third bearing seat can be finely adjusted. Similarly, by adjusting the second and fourth adjusting components, the two ends of the second roller 7 can be finely adjusted respectively. By finely adjusting the two ends of the first roller 6 and the second roller 7, the parallelism between the first roller 6 and the second roller 7 can be improved, which can effectively improve the consistency of the first roller 6 and the second roller 7 during the adjustment process, thereby improving the stability of the glass substrate during the pull-down process.

[0054] like Figures 1-2 As shown, in this embodiment, the hinge axes of the first lower swing arm 8, the second lower swing arm 9, the third lower swing arm, the fourth lower swing arm, the first upper swing arm 12, the second upper swing arm 13, the third upper swing arm, and the fourth upper swing arm are axially parallel to each other.

[0055] Specifically, ensuring that the hinge axes of the first lower swing arm 8, the second lower swing arm 9, the third lower swing arm, the fourth lower swing arm, the first upper swing arm 12, the second upper swing arm 13, the third upper swing arm, and the fourth upper swing arm are parallel to each other in pairs can guarantee the consistency of the movement of the first guide assembly and the second guide assembly, thereby improving the stability of the glass substrate during the pull-down process.
