Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of molten glass liquid homogenization, and in particular to a stirring device for glass substrate production. BACKGROUND

[0002] In the production of optoelectronic display glass substrates such as OLED, LTPS glass substrates and ultra-thin flexible glass substrates with a thickness less than 0.1mm, the glass material is first melted into molten glass liquid by a kiln and then clarified and homogenized through a platinum channel. Finally, the molten glass liquid is overflowed through the overflow brick and then drawn into a glass plate. In the homogenization process of the molten glass liquid, the stirring driving device drives the stirring rod to stir the molten glass liquid in the stirring barrel, so that the molten glass liquid is more uniform.

[0003] However, in order to facilitate the stirring member provided at the lower part of the stirring rod to pass through the opening of the stirring barrel, the size of the stirring member is smaller than the opening of the stirring barrel, which results in a large difference between the diameter of the stirring member and the inner diameter of the stirring barrel. Moreover, since the position of the stirring rod cannot be adjusted, the stirring range of the stirring rod is limited. The molten glass liquid in the middle of the stirring barrel can be fully stirred, while the molten glass liquid at the inner wall of the stirring barrel may not be fully stirred, which leads to a decrease in the uniformity of the molten glass liquid in the stirring barrel, and thus the formed optoelectronic display glass substrate may have stripe defects.

[0033] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but where appropriate, the techniques, methods, and devices should be considered as part of the specification.

[0034] As shown in Figure 1 and Figure 3 The utility model provides a kind of stirring device for glass substrate production (hereinafter referred to as stirring device), and the stirring device includes cantilever beam arm 1, stirring rod 2, driving mechanism 3 and angle adjusting mechanism 4. Cantilever beam arm 1 is located above stirring barrel 23. The upper portion of stirring rod 2 is circumferentially rotatably installed to cantilever beam arm 1, and the lower portion of stirring rod 2 can extend into stirring barrel 23 and is provided with stirring component 21. Driving mechanism 3 is installed to cantilever beam arm 1 and can drive stirring rod 2 to rotate circumferentially. Angle adjusting mechanism 4 is connected with cantilever beam arm 1 to support cantilever beam arm 1, and angle adjusting mechanism 4 can drive cantilever beam arm 1 to move, so that stirring component 21 moves towards the inner wall of stirring barrel 23.

[0035] Specifically, in the initial state, the angle adjusting mechanism 4 supports the cantilever beam 1, so that the cantilever beam 1 extends horizontally, the stirring rod 2 extends vertically, and the stirring component 21 of the stirring rod 2 extends into the stirring bucket 23. The driving mechanism 3 can drive the stirring rod 2 to rotate circumferentially around the axis thereof, so that the stirring component 21 stirs the molten glass liquid in the stirring bucket 23, and at this time, the molten glass liquid in the middle of the stirring bucket 23 can be fully stirred. The angle adjusting mechanism 4 drives the cantilever beam 1 to move (for example, drives the cantilever beam 1 to rotate vertically by a certain angle), and the cantilever beam 1 drives the stirring rod 2 to move, so that the stirring component 21 of the stirring rod 2 can move towards or away from the angle adjusting mechanism 4. However, no matter whether the stirring component 21 of the stirring rod 2 moves towards or away from the angle adjusting mechanism 4, the stirring component 21 moves towards the inner wall of the stirring bucket 23. When the stirring component 21 is close to the inner wall of the stirring bucket 23, under the driving of the driving mechanism 3, the stirring component 21 can fully stir the molten glass liquid at the inner wall of the stirring bucket 23. For example, referring to Figure 3 When the stirring component 21 moves away from the angle adjusting mechanism 4, the stirring component 21 is close to the right inner wall of the stirring bucket 23, and the stirring component 21 can fully stir the molten glass liquid located in the middle of the stirring bucket 23 and the molten glass liquid near the right inner wall of the stirring bucket 23. For another example, referring to Figure 4 When the stirring component 21 moves towards the angle adjusting mechanism 4, the stirring component 21 is close to the left inner wall of the stirring bucket 23, and the stirring component 21 can fully stir the molten glass liquid located in the middle of the stirring bucket 23 and the molten glass liquid near the left inner wall of the stirring bucket 23. Therefore, the stirring device for glass substrate production of the utility model can stir the molten glass liquid at the inner wall of the stirring bucket 23, and improve the uniformity of the molten glass liquid in the stirring bucket 23.

[0036] It should be noted that the preset value of the inclination angle of the stirring component 21 in the stirring bucket 23 is determined by the on-site operator according to the actual production situation of the glass substrate, and the utility model does not make any limitation.

[0037] As shown in Figure 3 and Figure 4 In some embodiments of the utility model, the angle adjusting mechanism 4 comprises a height adjusting mechanism 41 and a lifting driving mechanism 42, the top of the lifting driving mechanism 42 is rotationally connected with the end of the cantilever beam 1, and the lifting driving mechanism 42 can drive the end of the cantilever beam 1 to lift; the top of the height adjusting mechanism 41 is connected with the middle of the cantilever beam 1, and the height adjusting mechanism 41 is arranged to adjust the height of the middle of the cantilever beam 1; and the upper part of the stirring rod 2 is rotationally installed at the head end of the cantilever beam 1.

[0038] Specifically, in the initial state, the lifting driving mechanism 42 and the height adjusting mechanism 41 are kept at the same initial height to make the suspension beam arm 1 horizontal. After the driving mechanism 3 drives the stirring rod 2 to rotate to the normal rotating speed, the lifting driving mechanism 42 and the height adjusting mechanism 41 are lifted or lowered synchronously to change the relative height of the stirring part 21 in the stirring barrel 23. During the lifting adjustment process, the quality of the formed glass substrate at different heights is observed to determine the target height of the suspension beam arm 1. At the target height of the suspension beam arm 1, the height of the lifting driving mechanism 42 is kept unchanged, and the height of the height adjusting mechanism 41 is adjusted to make the suspension beam arm 1 rotate, so as to change the inclination angle of the stirring part 21 and make the stirring part 21 close to the inner wall of the stirring barrel 23, at this time, the stirring part 21 can uniformly stir the molten glass liquid at the inner wall of the stirring barrel 23. During the angle adjustment process, the quality of the generated glass substrate can be observed to determine the target inclination angle of the suspension beam arm 1. Of course, the inclination angle of the suspension beam arm 1 should be within a preset range to avoid the stirring part 21 contacting the inner wall of the stirring barrel 23.

[0039] In some embodiments of the utility model, the height adjusting mechanism 41 includes a fixed plate 413, a lifting plate 412 and a support base 411, the fixed plate 413 is located below the middle part of the suspension beam arm 1, the top of the fixed plate 413 is vertically spaced apart from the bottom of the suspension beam arm 1, the lifting plate 412 is installed on the side of the fixed plate 413 facing the stirring part 21, and the vertical position of the lifting plate 412 is adjustable, and the top of the lifting plate 412 is connected with the middle part of the suspension beam arm 1 through the support base 411.

[0040] Specifically, when the suspension beam arm 1 is at the target height, the suspension beam arm 1 is in a horizontal state, and the support base 411 is fixedly connected to the middle part of the suspension beam arm 1. Next, the inclination angle of the stirring rod 2 is adjusted, the bolt connecting the suspension beam arm 1 and the support base 411 is removed, the suspension beam arm 1 is separated from the fixation of the support base 411, then the vertical position of the lifting plate 412 is adjusted to make it rise or fall relative to the fixed plate 413, the support base 411 rises and falls with the lifting plate 412, thereby changing the height of the middle part of the suspension beam arm 1 to make the suspension beam arm 1 incline, and the stirring part 21 inclines and approaches the inner wall of the stirring barrel 23. After adjusting to the target inclination angle of the suspension beam arm 1, the bolt of the support base 411 is reinstalled, and the inclination angle of the suspension beam arm 1 is fixed through the support base 411, so that the stirring rod 2 continuously rotates to stir the molten glass liquid in the stirring barrel 23.

[0041] In some embodiments of the utility model, height adjusting mechanism 41 still includes base 4123, axial bearing, screw rod 4121 and connecting seat 4124, base 4123 is connected to the one side of fixed plate 413 towards stirring part 21, base 4123 is located below lifting plate 412, axial bearing is embedded in base 4123, connecting seat 4124 is connected to the one side of lifting plate 412 towards stirring part 21, connecting seat 4124 is equipped with the mounting hole of vertical through -extension, and the screw nut is arranged in the mounting hole, screw rod 4121 is located below cantilever arm 1 and is vertically spaced apart, and the bottom end of screw rod 4121 is installed to axial bearing, to enable the circumferential rotation of screw rod 4121, screw rod 4121 passes through mounting hole, and screw nut is screwed on screw rod 4121, to enable connecting seat 4124 can be vertically moved along screw rod 4121, lifting plate 412 is connected to the one side of fixed plate 413 towards stirring part 21 by slide rail sliding block mechanism.

[0042] Specifically, the one side of fixed plate 413 towards stirring part 21 is equipped with two vertical extension slide rails, and a plurality of sliding blocks are arranged on each slide rail, and all sliding blocks are connected to the one side of lifting plate 412 away from stirring part 21.Adjusting the inclination angle of cantilever arm 1, rotating screw rod 4121, make the screw nut fixed on lifting plate 412 drive lifting plate 412 vertically move along the slide rail, the support seat 411 fixed on the top of lifting plate 412 moves up and down with lifting plate 412, so that cantilever arm 1 moves vertically up or down with the movement of support seat 411.When cantilever arm 1 is at the target inclination angle, stop rotating screw rod 4121, and the middle part of cantilever arm 1 is reconnected to support seat 411.

[0044] Specifically, in order to facilitate the rotation of screw rod 4121, operating part 4122 is arranged at the top end of screw rod 4121, and the operating personnel can rotate screw rod 4121 by rotating operating part 4122 with a socket wrench to lift lifting plate 412.

[0046] Specifically, when adjusting the inclination angle of the cantilever beam 1, the bolts for fixing the support base 411 and the cantilever beam 1 are first disassembled, then the screw rod 4121 is rotated to drive the lifting plate 412 to lift the support base 411, and in the lifting process, the cantilever beam 1 rotates around the hinge point between the end of the cantilever beam 1 and the lifting driving mechanism 42, and the bottom surface of the cantilever beam 1 always keeps in contact with the top surface of the bottom plate 4111 of the support base 411. When the cantilever beam 1 is adjusted to the target inclination angle, the rotation of the screw rod 4121 is stopped, and the cantilever beam 1 is re-fixed on the support base 411 by bolts.

The piston rod of the hydraulic cylinder moves upward or downward, and the rotation of the screw rod 4121 drives the lifting plate 412 to move together with the piston rod, so that the cantilever beam 1 can always keep horizontal during the height change. When the cantilever beam 1 is lowered, the stirring part 21 of the stirring rod 2 gradually approaches the bottom of the stirring barrel 23, and when the cantilever beam 1 is raised, the stirring part 21 of the stirring rod 2 gradually approaches the top of the stirring barrel 23.
