Description

Technical Field

[0001] This utility model relates to the field of substrate glass technology, and in particular to a connection device between a liquid crystal substrate glass annealing furnace and a cross-cutting machine. Background Technology

[0002] The cross-cutting machine is a key process equipment in the glass forming process of G8.5+ and above substrates. In order to ensure that there is no relative displacement between the annealing furnace and the cross-cutting machine, including the consistency of cutting after glass forming, the two need to be connected by a connecting device.

[0003] Due to the high ambient temperature and fast production cycle in the substrate glass forming process, the structural characteristics, connection form, and service life of the connection device between the annealing furnace and the cross-cutting machine determine the consistency of glass cutting in the LCD substrate glass production line. This requires the connection device between the annealing furnace and the cross-cutting machine to have high temperature resistance, high mechanical properties, and high fatigue strength.

[0004] Furthermore, the existing connection device between the annealing furnace and the cross-cutting machine body is inconvenient to position during installation and hoisting, and the wire hole alignment is difficult. The mechanical strength of the connection device between the annealing furnace and the cross-cutting machine is insufficient in high-temperature environments, causing the cross-cutting machine to shake violently under the annealing furnace, making it impossible to ensure the consistency of the cut and broken glass products in terms of size. Utility Model Content

[0005] To address existing problems, this utility model provides a connection device between a liquid crystal substrate glass annealing furnace and a cross-cutting machine. The purpose is to ensure a firm alignment connection between the annealing furnace and the cross-cutting machine body through a hierarchical structural design (L-shaped plate, lifting plate) and detailed optimization (wire holes, narrowing, ribs), thereby avoiding poor cutting caused by glass substrate transport misalignment and affecting the yield of substrate production. Furthermore, the high temperature resistance and vibration resistance design ensure long-term stable operation.

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

[0007] A connection device for a liquid crystal substrate glass annealing furnace and a cross-cutting machine includes an L-shaped plate connecting the annealing furnace and a lifting plate connecting the cross-cutting machine body; reinforcing ribs are arranged side by side on the L-shaped plate; the lifting plate includes an upper plate and a lower plate; an upper rib is arranged side by side on one side of the upper surface of the upper plate; the other side of the upper surface of the upper plate is connected to the L-shaped plate; the lower surface of the lower plate is connected to the upper plane at the entrance of the cross-cutting machine body; multiple connecting ribs are arranged side by side and spaced apart between the upper plate and the lower plate.

[0008] As a further improvement of this utility model, the surface of the upper plate is longer than the surface of the lower plate in the direction perpendicular to the connection between the L-shaped plate and the hoisting plate.

[0009] As a further improvement of this utility model, a reinforcing rib is provided between the upper plate and the lower plate, and the reinforcing rib extends from the connecting rib.

[0010] As a further improvement of this utility model, the reinforcing rib is in the shape of a right triangle or a right trapezoid in the direction perpendicular to the upper plate.

[0011] As a further improvement of this utility model, a positioning cone pin is provided on the upper plate, and a positioning pin hole for installing the positioning cone pin is provided on the L-shaped plate.

[0012] As a further improvement of this utility model, the upper plate is provided with L-shaped wire holes.

[0013] As a further improvement of this utility model, the lower plate is provided with wire holes for the cross-cutting machine body.

[0014] As a further improvement of this utility model, the lifting plate is made of stainless steel.

[0015] As a further improvement of this utility model, the surface of the connecting rib plate narrows in width as it approaches the lower plate.

[0016] As a further improvement of this utility model, the surface of the upper plate is narrowed.

[0017] This utility model has the following beneficial effects:

[0018] This invention uses a combination of L-shaped plates and lifting plates to disperse the mechanical stress between the annealing furnace and the cross-cutting machine, preventing loosening of the connection due to equipment vibration or thermal deformation. The L-shaped plates and lifting plates respectively fix the outlet of the annealing furnace and the inlet of the cross-cutting machine body, ensuring that the axes of the two devices are aligned, reducing the risk of offset and vibration during the glass substrate transmission process, and preventing a reduction in the cutting quality of the cross-cutting machine. The screw connection simplifies the assembly process and facilitates later maintenance or replacement.

[0019] Preferably, the upper plate of the hoisting plate is longer than the lower plate, and the side is L-shaped. The extended part of the upper plate covers a larger area of ​​the bottom of the annealing furnace outlet, which enhances the support and resistance to high temperature areas. The L-shaped cross section provides higher torsional resistance and avoids deformation of the plate due to long-term heating or load.

[0020] Preferably, for the suspended area of ​​the extended portion of the upper plate, reinforcing ribs are used to prevent bending deformation caused by gravity or thermal expansion; reduce material fatigue and avoid cracks caused by stress concentration at the joint.

[0021] Preferably, the triangular / trapezoidal reinforcing ribs conform to the mechanical force transmission path, uniformly transferring the load to the lower plate and reducing stress concentration; the right-angled trapezoidal design can adapt to complex installation spaces and avoid interference with other equipment components.

[0022] Preferably, the positioning cone pin and the positioning pin hole cooperate to achieve the pre-positioning of the lifting plate and the cross-cutting machine body, avoiding the time-consuming adjustment of misalignment when tightening screws; the positioning cone pin is a mistake-proof design to ensure that the relative position of the lifting plate and the cross-cutting machine body strictly meets the process requirements, reducing human installation errors.

[0023] Preferably, the upper and lower plates are provided with through holes and screw holes. The through holes allow for fine adjustment of the screw position to accommodate the dimensional tolerances of the equipment interface or displacement caused by thermal expansion. The screw holes provide a variety of fastening point options to be compatible with different models of equipment or process upgrade needs.

[0024] Preferably, the lifting plate is made of stainless steel, which can withstand the high temperature environment (above 200-300℃) at the outlet of the annealing furnace, preventing the substrate glass material from softening or oxidizing and failing; stainless steel is corrosion resistant and can resist corrosion from chemical gases (such as SO2) that may be encountered during glass manufacturing, thus extending the life of the equipment.

[0025] Preferably, the connecting ribs narrow near the lower plate to reduce redundant material and overall weight, while maintaining the strength at the root of the ribs (where stress is greatest). The narrowed structure increases airflow space, which is beneficial for heat dissipation and avoids local overheating from affecting connection stability.

[0026] Preferably, the upper plate narrows on one side. The narrowed area reduces the heat transfer from the annealing furnace to the cross-cutting machine, preventing damage to the cross-cutting machine components due to high temperature. At the same time, the narrowed area helps to improve space utilization, adapt to narrow production line layouts, and avoid interference with other equipment (such as cooling fans).

[0040] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0041] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0042] Unless otherwise defined below, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] like Figure 1 As shown, a connection device between a liquid crystal substrate glass annealing furnace and a cross-cutting machine includes an L-shaped plate 2 connecting the annealing furnace 1, a lifting plate 7 connecting the cross-cutting machine body 8, and screws.

[0044] like Figure 2 As shown, the L-shaped plate 2 includes two mutually perpendicular connecting plates. One plate is connected to the annealing furnace 1 through the annealing furnace wire hole 4, and the other plate is connected to the cross-cutting machine lifting plate 7 through the positioning pin hole 6 and the lifting plate wire hole 5. Reinforcing ribs 3 are arranged side by side between the two connecting plates to strengthen the connection between them.

[0045] like Figure 3 As shown, the hoisting plate 7 sequentially includes an upper plate 10, a plurality of connecting ribs 12, and a lower plate 11; upper ribs 9 are arranged side-by-side on one side of the upper surface of the upper plate 10; the connecting ribs 12 are arranged side-by-side between the upper plate 10 and the lower plate 11. Figure 1 As shown, the upper surface of the upper plate 10 is connected to the L-shaped plate 2 by screws on the other side; the lower surface of the lower plate 11 is connected to the upper plane at the entrance of the cross-cutting machine body 8 by screws.

[0046] The upper plate 10 is longer than the lower plate 11 in the direction perpendicular to the connection between the L-shaped plate 2 and the lifting plate 7. The upper plate 10 is longer than the lower plate 11 and has an L-shaped side. The extended portion of the upper plate 10 covers a larger area at the bottom of the annealing furnace 1 outlet, enhancing its support and resistance to high-temperature areas. The L-shaped cross-section provides higher torsional resistance, preventing the plate from deforming due to long-term heating or load.

[0047] Example 1

[0048] In addition to the above-described embodiments, the lifting plate 7 in this embodiment also includes a positioning cone pin 15, which is disposed on the upper plate 10; a positioning pin hole 6 is also provided on a connecting plate of the L-shaped plate 2 for installing the positioning cone pin 15. The positioning cone pin 15 cooperates with the positioning pin hole 6 to achieve the pre-positioning of the lifting plate 7 and the L-shaped plate 2, avoiding the time-consuming adjustment of misalignment when tightening screws; the positioning cone pin 15 is a mistake-proof design to ensure that the relative position of the annealing furnace 1 and the cross-cutting machine body 8 strictly meets the process requirements, reducing human installation errors.

[0049] The upper plate 10 is provided with connecting L-shaped plate wire holes 14. The lower plate 11 is provided with connecting cross-cutting machine body wire holes 16. The wire holes provided in the upper plate 10 and the lower plate 11 provide multiple fastening point options to accommodate different equipment models or process upgrade needs.

[0050] The lifting plate 7 is made of 304 stainless steel. The screws are also made of 304 stainless steel. The stainless steel material of the lifting plate 7 can withstand the high-temperature environment (usually above 300℃) at the outlet of the annealing furnace 1, preventing material softening or oxidation failure; stainless steel is corrosion-resistant and can resist corrosion from chemical gases (such as SO2) that may be encountered during glass manufacturing, extending the life of the equipment.

[0051] The upper plate 10 has a narrowed surface. The narrowed area reduces the heat transfer from the annealing furnace 1 to the cross-cutting machine body 8, preventing damage to the components of the cross-cutting machine body 8 due to high temperature. At the same time, the narrowed area helps to improve space utilization, adapt to narrow production line layouts, and avoid interference with other equipment (such as cooling fans).

[0052] Example 2

[0053] The difference between this embodiment and Embodiment 1 is that:

[0054] like Figure 7 As shown, a reinforcing rib 13 is provided between the upper plate 10 and the lower plate 11 of the hoisting plate 7. The reinforcing rib 13 extends from the connecting rib 12 and is used to reinforce the extended portion of the upper plate 10.

[0055] For the suspended area of ​​the extended part of the upper plate 10, the reinforcing ribs 13 are used to prevent bending deformation caused by gravity or thermal expansion; reduce material fatigue and avoid cracks caused by stress concentration at the connection.

[0056] For the design verification of the stiffening rib 13, a static simulation analysis is now conducted, using Example 1 (without stiffening rib 13) and Example 2 (with stiffening rib 13) as comparison objects.

[0057] Example 1 vs Example 2

[0058]

[0059] As shown in the table above, by adding reinforcing ribs 13, the point of maximum stress on the lifting plate 7 shifts from the center of the inner side of the upper plate 10's extension to both sides of the inner side of the upper plate 10's extension, and the extreme value decreases by 79.8%; the point of maximum strain shifts from the center of the inner side of the upper plate 10's extension to both sides of the inner side of the upper plate 10's extension, and the extreme value decreases by 72.4%; the position of the maximum deformation displacement of the entire plate remains basically unchanged, but the extreme value decreases by 58.4%. Based on the above analysis, it can be seen that reinforcing ribs 13 avoid stress concentration on the lifting plate 7, reduce rib strain and displacement, and help improve the stability of the connection between the annealing furnace 1 and the cross-cutting machine body 8.

[0060] Example 3

[0061] The difference between this embodiment and Embodiment 1 is that:

[0062] 1) such as Figure 9 As shown, the reinforcing rib 13 is in the shape of a right triangle or a right trapezoid in the direction perpendicular to the surface of the upper plate 10.

[0063] 2) The width of the connecting rib plate 12 narrows as it approaches the lower plate 11.

[0064] The triangular / trapezoidal reinforcing ribs 13 conform to the mechanical force transmission path, uniformly transferring the load to the lower plate 11 and reducing stress concentration; the right-angled trapezoidal design can adapt to complex installation spaces and avoid interference with other equipment components.

[0065] The connecting rib 12 narrows near the lower plate 11, reducing redundant material and overall weight while maintaining the strength of the rib root (the point of maximum stress). The narrowed structure increases airflow space, which is beneficial for heat dissipation and avoids local overheating from affecting connection stability.

[0066] The working principle of this utility model is that the liquid glass 17 in the annealing furnace 1 overflows and forms a glass screen from top to bottom. When the cross-cutting machine body 8 is accurately aligned with the annealing furnace 1 (through the stable connection of the L-shaped plate 2 and the hanging plate 7), the cross-cutting machine body 8 cuts horizontally to cut the glass screen with knife marks, and then performs the subsequent plate-breaking process to cut the glass into the required size.

[0067] The above embodiments are merely one of the implementation methods for achieving the technical solution of this utility model. The scope of protection claimed by this utility model is not limited to this embodiment, but also includes any variations, substitutions, and other implementation methods that are easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
