Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise stated, the use of the directional terms "upper and lower" are generally relative to the normal operating conditions of the glass substrate conforming device, specifically, the direction toward the forming furnace is upward and the direction toward the lehr is downward (as can be seen with reference to the orientation shown in fig. 1) when the conforming device is operating, and further, "inner and outer" refer to the inner and outer of the specific structural profile. In addition, terms such as "first", "second", and the like are used to distinguish one element from another, and are not sequential or important.

As shown in fig. 1 to 3, the present disclosure provides a glass substrate conforming apparatus as a connecting structure for connecting a forming furnace and an annealing furnace through which a glass substrate 10 enters the annealing furnace after being formed by the forming furnace, the conforming apparatus may include an upper plate 1, a lower plate 2, a side plate 3, and a heating device 4, the upper plate 1 and the lower plate 2 may be disposed opposite to each other, the upper plate 1 may be used for connecting with the forming furnace, the lower plate 2 may be used for connecting with the annealing furnace, the side plate 3 may be connected between the upper plate 1 and the lower plate 2 to enclose a cavity 5 with the upper plate 1 and the lower plate 2, a first opening 11 for the glass substrate 10 to pass through and enter the cavity 5 is formed on the upper plate 1, a second opening 21 for the glass substrate 10 to pass through and exit the cavity 5 is formed on the lower plate 2, and the heating device 4 is installed in the cavity 5. In a specific working state, because the upper end of the forming furnace and the lower end of the annealing furnace are provided with the glass pulling rolls, the glass pulling rolls can play a role in guiding the movement of the glass substrate among the forming furnace, the compliance device and the annealing furnace, so that the glass substrate 10 can smoothly pass through the first opening 11 and enter the compliance device after leaving the forming furnace, and the glass substrate 10 can also smoothly move from the first opening 11 to the second opening 21 and enter the annealing furnace through the second opening 21.

Through the technical scheme, the heating device is arranged in the compliance device, and the glass substrate 10 passing through the interior of the compliance device can be subjected to heating treatment, so that the temperature requirement of annealing stress relief required when the glass substrate 10 enters the annealing furnace due to the fact that the temperature of the glass substrate is reduced too fast in the compliance device from top to bottom is avoided, and the annealing furnace is prevented from manufacturing the glass substrate with the stress performance not reaching the standard, and the quality of the glass substrate is influenced. In addition, since the compliance device is a cavity surrounded by the upper plate 1, the lower plate 2 and the side plate 3, the upper plate 1, the lower plate 2 and the side plate 3 can protect the glass substrate 10 in the cavity well, prevent the glass substrate 10 from being damaged, and prevent impurities such as dust particles in the environment from attaching to the surface of the glass substrate 10.

Further, as shown in fig. 2 and 3, the shape of the first opening 11 and the shape of the second opening 21 are configured to fit the glass substrate 10, the length direction of the first opening 11 is parallel to the length direction of the second opening 21, and the heating device 4 may extend along the length direction of the first opening 11. Here, since the shape of the first opening 11 and the shape of the second opening 21 are adapted to the shape of the glass substrate 10 so that the glass substrate can pass through the first opening 11 and the second opening 21, the length direction of the first opening 11 and the second opening 21 is the width direction of the glass substrate 10, which is the direction perpendicular to the moving direction of the glass substrate 10. The heating device 4 extends along the length direction of the first opening 11, that is, the heating device 4 can extend along the width direction of the glass substrate 10, so that when the glass substrate 10 moves from top to bottom in the cavity 5, the heating device 4 can heat along the width direction of the glass substrate 10, thereby heating the whole glass substrate 10 in the process that the glass substrate 10 moves from top to bottom, and ensuring that the temperature of the glass substrate 10 can meet the initial temperature requirement of annealing destressing of the annealing furnace when the glass substrate 10 reaches the second opening 21, so as to manufacture the glass substrate 10 with the stress performance meeting the requirement, and improve the quality of the glass substrate 10.

Here, the heating device 4 extending in the longitudinal direction of the first opening 11 means that the heating device 4 may be one, the entire length of which extends in the longitudinal direction of the first opening 11, or the heating device 4 may be plural, and the plural heating devices 4 are arranged at intervals in the longitudinal direction of the first opening 11 (i.e., the width direction of the glass substrate). Because a plurality of heating wires are usually arranged in the forming furnace at intervals, when the heating device 4 is arranged in the compliance device, the heating device 4 can be arranged into a plurality of heating wires, so that the heating device 4 in the compliance device is staggered with the heating wires in the forming furnace, namely, the heating device 4 in the compliance device is positioned between two adjacent heating wires in the forming furnace, so that the heating device 4 can compensate the temperature difference of the glass substrate 10 in the forming furnace along the width direction due to uneven heating, the glass substrate with smaller temperature difference is conveyed for the annealing furnace, and the quality of products is improved.

Further, as shown in fig. 1, the heating device 4 may include a housing 41 installed in the cavity 5 and a heating wire 42 disposed in the housing 41, and the housing 41 may protect the heating wire 42 disposed therein, thereby increasing the service life of the heating wire 42. In one embodiment, the housing may be made of a high-strength and high-temperature resistant heat-resistant steel material, such as 0Cr25ni20 stainless steel, or may be made of SiC material with high heat conductivity and low strength, which is not limited by the disclosure. The heating wire 42 may extend along the length direction of the first opening 11 and be spaced apart from the glass substrate 10 by a certain distance to heat the glass substrate 10 in the width direction, and when the glass substrate 10 moves past the heating wire 42 from the top to the bottom in the cavity 5, the heat generated by the heating wire 42 may heat the glass substrate 10, so that the initial temperature of the glass entering the annealing furnace satisfies the requirement of annealing destressing. The terminals 8 of the heating wire 42 are used for connection with an external power source, and the heating wire 42 is supplied with power by the external power source to generate heat to heat the glass substrate 10. In other embodiments, the heating device may also use other types of heating devices such as a heating tube, a heating belt, a warm air blower, or a heating plate through which high-temperature fluid flows, and the disclosure is not limited thereto.

As shown in fig. 1, the heating wires 42 may be plural, and the plural heating wires 42 may be disposed in the casing 41 at intervals in the up-down direction, so as to improve the heating range of the heating device 4, when the glass substrate 10 passes through the plural heating wires 42, the plural heating wires 42 can both realize heating of the glass substrate 10, for example, after the heating of the upper heating wire 42 is completed, the lower heating wire 42 can continue to heat the glass substrate 10, so as to more effectively realize the heating treatment of the glass substrate 10, the heating effect is better, and the heating efficiency is higher. The plurality of heating wires 42 may be connected in series and led out through the same terminal 8 to be connected to an external power source, and the plurality of heating wires 42 may be independent of each other and led out through the plurality of terminals 8 to be connected to the external power source, respectively, which is not limited in the present disclosure.

Further, as shown in fig. 1, to facilitate the installation of the heating device 4, the compliance device may further include a mounting bracket 6, and the mounting bracket 6 may be formed in an L-shape and include a first mounting plate 61 and a second mounting plate 62; the first mounting plate 61 may be fixed to the upper plate 1, the second mounting plate 62 may extend from the first mounting plate 61 toward the lower plate 2, and the housing 41 may be mounted on the second mounting plate 62, or; the first mounting plate 61 may be fixed to the lower plate 2, the second mounting plate 62 may extend from the first mounting plate 61 toward the upper plate 1, and the housing 41 may be mounted on the second mounting plate 62. Since the mounting bracket 6 is formed in an L-shaped structure and the second mounting plate 62 extends from the upper plate 1 toward the lower plate 2 or from the lower plate 2 toward the upper plate 1, the heating device 4 can be located as centrally as possible in the compliant device, thereby heating the cooled glass substrate 10 in a targeted manner. In addition, the mounting bracket 6 provides a mounting pivot for the heating device 4, so that the structural stability of the heating device 4 is ensured, and the mounting bracket 6 is compact in structure and reasonable in design, so that the heating device 4 can be conveniently mounted. In other embodiments, the housing 41 may be directly mounted to the upper plate 1, the lower plate 2, or the side plate 3 by fasteners.

Specifically, the first mounting plate 61 and the second mounting plate 62 may be formed as an integrally formed sheet metal component structure, the first mounting plate 61 may be fixedly connected to the upper plate 1 or the lower plate 2 by bolts or welding, and the housing 41 may also be fixedly connected by bolts or welding, so as to ensure the mounting stability and further improve the service life of the compliance device.

The housing 41 may be an integrally formed structure, the upper panel 411 and the lower panel 412 may be fixed on the second mounting plate 62 by welding or bolting, and the heating wire 42 may be disposed in the U-shaped housing 41, so as to effectively prevent the broken glass from falling onto the heating wire 42 under abnormal conditions such as breakage and plate breakage of the glass substrate 10, which may cause a short circuit of the heating wire 42, that is, the housing 41 may effectively protect the heating wire 42. In addition, the connection plate 413 may be formed with a plurality of rows corresponding to the heating wires 42, and each row may be arranged along the extending direction of the heating wires 42 to improve the emissivity of the heating wires 42, and optionally, each of the heating wires 42 is disposed opposite to each row to further improve the emissivity more effectively.

That is, the upper panel 411 is obliquely disposed at an angle to the horizontal direction, and the connection plate 413 is obliquely disposed and gradually decreases in distance from the glass substrate 10 in a direction from the upper panel 411 to the lower panel 412. Thus, when the glass substrate 10 is broken or broken, when the broken glass falls onto the upper panel 411, the upper panel 411 forms an angle with the horizontal direction, and the broken glass can slide down along the upper panel 411 extending obliquely downwards and the connecting plate 413 in an oblique shape under the action of gravity, so as to prevent the broken glass substrate from being accumulated on the housing 41, and influence on heat dissipation of the heating wire 42 and damage the structure of the housing 41. Alternatively, as an embodiment, the lower panel 412 may be horizontally disposed, that is, the lower panel 412 may be parallel to the horizontal direction so as to form an acute angle with the connecting panel 413.

In terms of material selection, as an exemplary embodiment of the present disclosure, the furnace plate 43 may be made of a material such as high temperature resistant sillimanite or mullite, and the heating wire 42 may be made of an APM material with high temperature resistance and good stability, so as to avoid the situation of power instability or short circuit caused by thermal expansion deformation, and the present disclosure does not limit the material of the furnace plate 43 and the heating wire 42.

As shown in fig. 1, the terminal 8 of the heating wire 42 can pass through the side plate 3 and be connected with an external power supply, so as to supply power to the heating wire 42, and when the side plate 3 is penetrated, the insulating sleeve 7 can be sleeved outside the terminal 8 to realize insulation with the side plate 3, and the insulating sleeve 7 can be made of materials such as a corundum tube, so as to improve the insulation effect.

In addition, the side plates 3 may be flexible side plates so that the distance between the upper plate 1 and the lower plate 2 may be adaptively adjusted according to the distance between the forming furnace and the annealing furnace, improving the versatility of the compliance device of the present disclosure.

To avoid too fast heat loss in the compliant device, the side plates may be made of a thermal insulation material, such as thermal insulation cotton, to insulate the glass substrate 10 in the compliant device, thereby improving the heating effect and avoiding heat loss.
