Description

Technical Field

[0001] This invention belongs to the field of manufacturing technology of liquid crystal substrate glass forming equipment, and relates to an installation tool and method for a heat dissipation box of a liquid crystal glass substrate forming furnace. Background Technology

[0002] In the process of producing liquid crystal glass substrates using the overflow pull method, the flow and forming state of the molten glass in the forming furnace directly determines the thickness uniformity of the glass substrate. The viscosity of the molten glass is a key parameter affecting the thickness formation, and viscosity is extremely sensitive to temperature changes. Therefore, the vapor chamber within the forming furnace, composed of multiple silicon carbide (SiC) vapor chamber plates, must provide a highly uniform temperature environment. SiC material, due to its rapid thermal conductivity and uniform heat distribution, is widely used in vapor chamber plate manufacturing, helping to maintain a stable thermal environment.

[0003] However, with the increasing demand for high-generation, high-capacity LCD glass substrates, the overall size of the equipment is constantly increasing, and the heat spreader chamber inside the molding furnace is also becoming longer, requiring more heat spreaders, which significantly increases the complexity of installation. The original installation method involved installing the left and right chambers separately, using a center line and plumb lines to measure and position them, supplemented by a steel ruler. This method was not only cumbersome and time-consuming, but also had problems such as large reading errors and difficulty in ensuring installation accuracy. Furthermore, the retesting process was difficult to accurately verify the position of the chambers. The resulting installation deviations easily caused uneven temperature distribution inside the heat spreader chamber, which in turn interfered with process stability and seriously affected product yield and normal production operation. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of poor temperature field uniformity in existing heat spreader installations, which rely on manual measurement, are inefficient, and cannot guarantee symmetry accuracy. This invention provides an installation tool and method for heat spreaders in liquid crystal glass substrate molding furnaces, achieving a standardized, intuitive, and efficient installation process. This solution simplifies complex multi-dimensional spatial positioning into a single "fitting" operation using a rigid installation tool that integrates precise surface spacing and alignment references. This not only completely eliminates human measurement errors and ensures precise consistency in heat spreader spacing and alignment, but also significantly reduces operational difficulty and time costs, thus providing a fundamental guarantee for constructing a symmetrical and uniform temperature field in the molding furnace.

[0005] To achieve the above objectives, the present invention employs the following technical solution: In a first aspect, the present invention provides an installation tool for a homogenizing chamber of a liquid crystal glass substrate molding furnace, the installation tool being a rigid body including a lower bonding surface and an upper bonding surface; The lower bonding surface includes two opposing first bonding surfaces and a second bonding surface; the distance between the first bonding surface and the second bonding surface matches the design surface distance of the heat exchange box. The upper bonding surface is located at the center of the lower bonding surface and coincides with the center of the lower bonding surface.

[0006] Preferably, the distance between the first and second mating surfaces is equal to the design surface distance of the heat exchange box, with a tolerance of ±0.02mm.

[0007] Preferably, the top of the upper bonding surface is provided with a central positioning groove along its length.

[0008] Preferably, the width of the central positioning groove is adapted to the diameter of the thin rope used to calibrate the center line of the molding furnace.

[0009] Secondly, the present invention provides a method for installing a heat exchange chamber in a liquid crystal glass substrate molding furnace, comprising the following steps: S1. Set a taut thin rope at the center of the forming furnace as the center line of the forming furnace; S2. Place the left and right heat-spreading plates on the mounting positions of the heat-spreading box of the molding furnace, and apply a pre-tightening force to keep the left and right heat-spreading plates stable in the mounting positions and able to move under the action of external force. S3. Place the installation tool between the left heat exchange plate and the right heat exchange plate, and adjust the position of the installation tool so that the first contact surface of the installation tool is in contact with the left heat exchange plate and the second contact surface is in contact with the right heat exchange plate. S4. Adjust the position of the left heat spreader and / or the right heat spreader so that the upper contact surface of the installation tool is in contact with the center line of the molding furnace. S5. Secure the left and right heat spreaders; S6. Repeat S2~S5 until all left and right heat spreaders are installed.

[0010] Preferably, when adjusting the position of the left and / or right heat spreaders, fine adjustments are made by gently tapping the non-working surfaces of the heat spreaders.

[0011] Preferably, the repeated installation sequence is along the extension direction of the center line of the molding furnace, proceeding sequentially from one end of the molding furnace to the other.

[0012] Preferably, the mounting positions of the heat exchange box of the molding furnace are symmetrically arranged about the center line of the molding furnace.

[0013] Preferably, the symmetrical position tolerance of the left and right heat spreaders relative to the center line of the forming furnace is less than 0.05 mm.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention transforms complex spacing measurements into a single, reliable bonding action by precisely matching the designed surface distance between the two opposite sides of the lower bonding surface, fundamentally eliminating the cumulative error of step-by-step measurements. Simultaneously, by precisely positioning the upper bonding surface at the center of the lower bonding surface, it cleverly combines the precision requirements of spacing control and centering into one. This allows operators to simultaneously and efficiently complete the high-precision positioning of the left and right heat exchange plates simply by ensuring the upper bonding surface is aligned with the center line, greatly simplifying operation and improving installation efficiency and first-time success rate.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings: The first objective of this invention is to provide an installation tool for the heat spreader of a liquid crystal glass substrate molding furnace, such as... Figure 1 As shown, the installation tool 4 is a rigid body, including a lower contact surface 6 and an upper contact surface 7; The lower bonding surface 6 includes two opposing first bonding surfaces and a second bonding surface; the distance between the first bonding surface and the second bonding surface matches the design surface distance of the heat exchange box. The upper bonding surface 7 is located at the center of the lower bonding surface 6 and coincides with the center of the lower bonding surface 6.

[0025] The installation tool 4 provided by this invention simplifies complex spatial dimensions and alignment precision control into a single intuitive and reliable operation through an integrated structural design. The rigid body of the tool 4 ensures dimensional constancy and operational stability. The first and second mating surfaces serve as distance references, allowing for precise setting of the design surface distance between the left and right heat spreaders in a single placement, fundamentally eliminating the cumulative error of step-by-step measurements. The upper mating surface 7, located at the center of the lower mating surface 6, serves as an alignment reference, guiding the left and right heat spreaders to precise symmetrical positions by comparing them with the pre-set furnace centerline. This design internalizes high-precision distance and alignment requirements into the tool itself. Operators no longer need to perform tedious measurements and calculations; they can simultaneously complete positioning and alignment through simple "placement" and "matting" actions, greatly improving installation efficiency and first-time success rate, and significantly reducing reliance on operator skill and experience.

[0026] The distance between the first and second mating surfaces is equal to the design surface spacing of the heat exchanger, with a tolerance of ±0.02mm. During installation, when the installation tool 4 is placed between the left and right heat exchangers, its lower mating surface can simultaneously contact the inner surfaces of both heat exchangers, thus directly and accurately replicating and locking the crucial design spacing between them. This fundamentally replaces the outdated method of relying on repeated measurements with rulers and manual readings, not only completely eliminating reading errors caused by differences in personal perspective or operation, but also transforming complex distance control into a simple and reliable "matting" action, ensuring the accuracy and consistency of the spacing between all heat exchangers along the length of the entire heat exchanger.

[0027] The top of the upper bonding surface 7 is provided with a central positioning groove along its length, and the width of the central positioning groove is adapted to the diameter of the thin rope 5 used to calibrate the center line of the molding furnace. As a precision mechanical guide structure, this groove can stably accommodate and hold the thin rope used as a reference, thereby effectively eliminating symmetry errors caused by rope swaying, operator's viewing angle deviation, or slight tool tilt during visual alignment, ensuring that the alignment process between the installation tool and the center line of the furnace body is faster, more accurate, and more reliable.

[0028] A second objective of this invention is to provide a method for installing a heat exchange chamber in a liquid crystal glass substrate molding furnace, such as... Figures 2-4 As shown, it includes the following steps: S1. Set a taut thin rope at the center of the molding furnace as the center line 5 of the molding furnace; S2. Place the left heat-spreading plate 2 and the right heat-spreading plate 3 on the mounting position 1 of the heat-spreading box of the molding furnace, and apply a pre-tightening force to keep the left heat-spreading plate 2 and the right heat-spreading plate 3 stable on the mounting position 1 and able to move under the action of external force. S3. Place the installation tool 4 between the left heat exchange plate 2 and the right heat exchange plate 3, and adjust the position of the installation tool 4 so that the first contact surface of the installation tool 4 is in contact with the left heat exchange plate 2 and the second contact surface is in contact with the right heat exchange plate 3. S4. Adjust the position of the left heat spreader 2 and / or the right heat spreader 3 so that the upper contact surface 7 of the installation tool 4 is in contact with the center line 5 of the molding furnace. S5. Secure the left heat spreader 2 and the right heat spreader 3; S6. Repeat S2~S5 until all left-side heat spreaders 2 and right-side heat spreaders 3 are installed.

[0029] The method of this invention establishes a stable and visible longitudinal center reference using a taut thin rope. Subsequently, a temporary "fine-tuning-locking" system is constructed by combining a pre-tightened heat spreader with a dedicated installation tool 4. Furthermore, by simultaneously bridging the left and right heat spreaders using the installation tool and aligning their mating surfaces with the center line, this step synchronously and automatically achieves precise control of the spacing between the left and right plates and their symmetrical positioning relative to the furnace center line, transforming the complex measurement and adjustment process into an intuitive "fitting" action. This process not only ensures that each pair of heat spreaders can quickly and accurately reach the designed position, eliminating the cumulative errors of step-by-step installation, but also enables the entire lengthy heat spreader to be assembled with extremely high efficiency and consistency, ultimately providing a fundamental guarantee for forming a uniform and stable temperature field within the molding furnace.

[0030] When adjusting the position of the left heat spreader 2 and / or the right heat spreader 3, fine adjustments are made by gently tapping the non-working surface of the heat spreader. By applying a gentle impact to the non-working surface, any mechanical damage to the delicate working surface or fragile edges of the heat spreader can be effectively avoided. At the same time, this fine-tuning method provides extremely high operational sensitivity, allowing the operator to guide the bulky heat spreader into place with micron-level control precision, overcoming sliding friction resistance and avoiding over-adjustment or jamming that may be caused by direct forceful pushing or pulling.

[0031] The installation sequence is along the extension direction of the centerline 5 of the molding furnace, proceeding sequentially from one end of the furnace to the other. This orderly advancement method ensures that each pair of installed and secured heat spreaders provides a stable and reliable axial reference for the subsequently installed adjacent pairs. This effectively avoids the accumulation of errors and misalignments that may occur with installation from the middle to both ends or in a skip-installation manner, ensuring that the entire heat spreader forms a straight, continuous, and sealed space along its length.

[0032] The mounting positions 1 of the heat spreader housing of the molding furnace are symmetrically arranged about the center line 5 of the molding furnace (tolerance less than 0.05mm). This controls macroscopic systematic deviations to a very small range from the outset, ensuring the precise positioning of each pair of heat spreaders using installation tools. This high-precision precondition not only significantly reduces the difficulty and workload of adjustments during on-site installation, but also fundamentally guarantees that the final assembled heat spreader housing can achieve a perfect spatial mirror image on both sides, thus providing the most fundamental structural guarantee for forming an absolutely uniform and symmetrical temperature field inside the molding furnace.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
