Description

Technical Field

[0001] This invention relates to the field of special glass technology, specifically to a heat treatment processing equipment for vehicle-mounted special glass covers. Background Technology

[0002] With the continuous upgrading of vehicle intelligence, vehicle body lightweighting, and driving safety standards, automotive special glass covers (including window protection glass, vehicle display glass, and cabin protective tempered glass) have extremely high requirements for flatness, structural strength, internal stress uniformity, and explosion resistance. The heat treatment annealing process is a core step that determines the quality and safety of the finished product. Currently, in the production and processing of automotive special glass covers, the heat treatment annealing process generally relies on traditional integrated annealing furnaces to complete the heating, holding, and cooling operations. However, existing processing equipment and supporting processes still have many industry shortcomings and technical defects, making it difficult to meet the demands of high-precision, high-yield, large-scale production.

[0003] Currently, conventional annealing furnaces generally suffer from uneven temperature distribution within the furnace. They mostly adopt a top-mounted single straight pipe direct air supply mode, which can only achieve localized heating of the upper surface of the glass. This easily leads to temperature difference defects such as the upper surface being hot and the lower surface being cold, the center being overheated, and the edges being too cool. The large differences in the heating gradient between the upper and lower surfaces of the glass, as well as between the center and the corner areas, result in incomplete release of internal stress during heat treatment. This can easily cause the glass cover to warp and deform, exceed the standard for surface flatness, and leave hidden cracks. During later use in vehicles, spontaneous explosions and cracks are likely to occur, seriously affecting the vehicle's safety performance. Summary of the Invention

[0004] The purpose of this invention is to provide a heat treatment processing equipment for vehicle-mounted special glass covers, in order to solve the problem of uneven temperature distribution in existing conventional annealing furnaces mentioned in the background art. These furnaces often adopt a top single straight pipe direct air blowing mode, which can only achieve local heating of the upper surface of the glass, and is prone to temperature difference defects such as hot at the top and cold at the bottom, overheating in the center and coolness at the edges.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat treatment processing equipment for vehicle-mounted special glass covers, comprising: a frame, an annealing furnace fixedly installed on the side of the top of the frame, a temperature control component fixedly installed on the top of the annealing furnace, sealing doors movably installed on both sides of the outer surface of the annealing furnace, and a guide component fixedly installed near the sealing doors of the annealing furnace. A temperature equalization component is fixedly installed at the middle of the top of the frame and is located inside the cavity of the annealing furnace. The temperature control component is located above the temperature equalization component. The temperature uniform assembly includes a base plate, with a heat spreader and a shim fixedly installed at the center of the top of the base plate. Adjustable support rods are symmetrically installed on both sides of the outer surface of the heat spreader, and a support component is slidably installed on the surface of each support rod. The baffles on both sides of the placement plate form a limiting barrier to prevent the glass from shifting, moving, or slipping during pushing, heating, thermal expansion, and airflow disturbance. The bottom of the glass is suspended above the placement plate, not directly touching the plate surface, leaving space for heat exchange. The heat spreader is centrally located above the base plate and directly below the placement plate, continuously and evenly concentrating and conducting the radiant heat from the furnace bottom and the cavity temperature field upwards, providing stable auxiliary heating to the bottom surface of the glass and eliminating bottom temperature differences.

[0006] Furthermore, the base plate is fixedly installed at the middle of the top of the frame, and the shims are set at both ends of the heat spreader plate and fixedly installed between opposite surfaces of the inner wall of the annealing furnace. The height of the shims is flush with the guide assembly and the support component. The heat spreader plate homogenizes the heat energy in the furnace a second time, forming a flat heat field upwards, solving the defects of traditional furnaces that are "hot at the top and cold at the bottom, overheated in the middle and cool at the edges". This allows the bottom surface of the glass to be heated gently and evenly, suppressing internal residual stress and reducing the risk of warping, hidden cracks, and subsequent spontaneous breakage from the source.

[0007] Furthermore, the support component includes two slides, each with a fixed block fixedly mounted on its surface. A placement plate is fixedly mounted between the opposing surfaces of the fixed blocks. Symmetrical baffles are mounted on both sides of the outer surface of the placement plate, and a flow groove is formed on its surface. The slides move the fixed blocks and placement plates synchronously, adjusting the height of the placement plate until it is flush with the shims, facilitating the subsequent entry of the glass cover plate into the annealing furnace. The shims are fixed between the two ends of the heat spreader and the inner wall of the furnace, pre-calibrated to the same horizontal level with the guide assembly and placement plates to form a seamless conveying platform. The glass cover plate, conveyed by the guide rollers of the guide assembly, smoothly slides into the furnace along the shims and lands precisely above the placement plates on both sides.

[0008] Furthermore, the carriage is movably mounted on the surface of the adjusting bracket, the placement plate is mounted above the heat spreader, and the vehicle-mounted glass cover is placed above the placement plate. Multiple sets of flow channels are formed on the surface of the placement plate, allowing hot air from the furnace to penetrate and circulate through these channels. Layered hot air from the upper temperature control component covers the upper surface of the glass, and the hot air passes through the flow channels directly to the lower side of the glass and the heat spreader area, achieving uniform heating of the glass across its entire surface (upper, middle, and lower), without dead zones or localized hot or cold areas.

[0009] Furthermore, the temperature control component includes a top plate, with a fixing plate fixedly installed at the bottom of the top plate. Two sets of diversion pipes are fixedly installed on the surface of the fixing plate, extending through the fixing plate and the top plate to their exterior. The fixing plate neatly and precisely positions the two sets of diversion pipes, ensuring that all air outlets are accurately aligned with the area above the furnace's onboard glass cover, guaranteeing direct delivery of hot and cold air to the work area without deviation or dispersion. The upper end of the diversion pipes connects to an external hot and cold air supply unit, enabling one-button switching and variable frequency adjustment of hot and cold air sources, thus establishing a complete hot and cold air supply circuit in advance.

[0010] Furthermore, the top plate is fixedly installed on the top of the annealing furnace, and the diversion pipe assembly is mounted above the vehicle-mounted glass cover via the top plate. The diversion pipe assembly is connected to the temperature control equipment via pipelines.

[0011] Furthermore, the distribution pipe assembly includes a connecting pipe, the inner wall of which is fixedly installed with a through rod. Inside the connecting pipe, a partition pipe and an inner layer pipe are respectively fixedly installed via the through rod. During furnace heating, high-temperature hot air is concentrated and drawn in through the connecting pipe. Relying on the internal through rod for reinforcement and separation, the hot air is stably distributed to the multi-layered flow channels formed by the inner layer pipe and the partition pipe. The inner layer pipe delivers the main hot air, focusing on heating the central area of ​​the glass. The partition pipe forms an annular auxiliary air duct, supplementing the glass edges with hot air, achieving full-area hot air coverage. The layered and pressure-stabilized hot air is evenly blown out from the lower end of the distribution pipe assembly, covering the upper surface of the glass from top to bottom. Combined with the flow channels of the lower temperature equalization component, the hot air penetrates the channels and reaches the bottom of the glass, forming a continuous hot air constant-temperature field, achieving uniform heating and constant-temperature insulation, and fully releasing the internal stress of the glass.

[0012] Furthermore, the connecting pipe is fixedly installed on the top of the fixed plate, and the connecting pipe, partition pipe, and inner layer pipe are configured as a multi-layer structure. During the furnace cooling time, the external unit switches to supply low-temperature cold air. The cold air is also distributed and stabilized along the multi-layer pipeline, and slowly delivered into the furnace to avoid direct cold air blowing or excessive wind speed causing localized sudden cooling. The through rod keeps the multi-layer pipe body coaxial and stable throughout the process, preventing the pipeline from deforming due to thermal expansion and contraction when hot and cold air flows alternately. At the same time, it isolates air leakage in the air duct and ensures that the hot air and cold air have their own independent and unobstructed flow channels. After the annealing furnace heat preservation is completed, the low-temperature cold air supply is switched, and the multi-layer air duct slowly releases air. The cold air gently covers the glass plate surface to achieve gradient and slow cooling, preventing single-point rapid cooling from causing new internal stress, cracks, and warping.

[0013] Furthermore, the guiding assembly includes a mounting base, of which two sets are provided. An inclined frame is fixedly mounted on the top of each set of mounting bases, and guide rollers are rotatably mounted between the opposing surfaces of the inclined frames. Before starting the equipment, the operator places the special vehicle-mounted glass cover to be heat-treated on the upper end of the inclined frame of the guiding assembly on the feeding side of the annealing furnace, ensuring the bottom of the glass cover is in contact with the surface of the guide rollers. After receiving the start signal from the equipment control system, the guide rollers rotate uniformly along their own axis, using rolling friction to drive the glass cover to slide downwards along the inclined direction of the inclined frame, moving it towards the interior of the annealing furnace. After being conveyed by the guide rollers to the lower end of the inclined frame, the glass cover is aligned with the height of the shim block of the temperature equalization assembly. The guide rollers continue to rotate, smoothly moving the glass cover to the surface of the shim block. After the shim block receives the glass cover, it further guides it to the temperature equalization assembly. At this point, the glass cover is completely within the support range of the temperature equalization assembly, completing precise positioning within the furnace. During the conveying process, the tilting frame and the raised block form a seamless conveying plane, and the rolling thrust of the guide rollers continuously acts on the glass cover plate, ensuring that it enters the core processing area of ​​the furnace cavity without deviation or collision.

[0014] Furthermore, the mounting base is fixedly installed on both sides of the annealing furnace, and the tilting frame, the shim, and the placement plate are set at the same height. The tilting frame and the shim cooperate to guide the vehicle-mounted glass cover. After the vehicle-mounted special glass cover completes the uniform temperature heat treatment in the furnace, the equipment control system triggers a discharge command, the sealing door on the discharge side of the annealing furnace opens, and at the same time, the guide rollers of the discharge-side guiding component rotate in the opposite direction. The rotating guide rollers cooperate with the placement plate and the shim to smoothly export the glass cover from the support of the uniform temperature component, move it along the surface of the shim towards the upper end of the tilting frame, and slide the glass cover upward along the tilting direction of the tilting frame. The guide rollers continuously provide rolling support, reducing friction between the glass and the tilting frame and preventing scratches or damage to the surface of the glass cover.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (i) In the heat treatment processing equipment for vehicle-mounted special glass covers, after the vehicle-mounted special glass cover has completed the uniform temperature heat treatment in the furnace, the equipment control system triggers the discharge command, the sealing door on the discharge side of the annealing furnace is opened, and at the same time the guide rollers of the discharge side guide assembly rotate in the opposite direction. The rotating guide rollers cooperate with the placement plate and the shim block to smoothly export the glass cover from the support of the uniform temperature assembly and move it along the surface of the shim block to the upper end of the tilting frame. The glass cover slides upward along the tilting direction of the tilting frame. The guide rollers continuously provide rolling support to reduce the friction between the glass and the tilting frame and avoid scratches or damage to the surface of the glass cover.

[0016] (II) The heat treatment equipment for special glass covers on this vehicle has baffles on both sides of the placement plate to form a limiting barrier, preventing the glass from shifting, moving, or slipping during pushing, heating, thermal expansion, and airflow disturbance. The bottom of the glass is suspended above the placement plate, not directly touching the solid surface, leaving space for heat exchange. The heat spreader is centrally located above the base plate and directly below the placement plate, continuously and evenly concentrating and conducting the radiant heat from the furnace bottom and the temperature field of the cavity upwards, providing stable auxiliary heating to the bottom surface of the glass and eliminating bottom temperature differences. The heat spreader further homogenizes the heat energy inside the furnace, forming a flat heat field upwards, solving the defects of traditional furnaces where "the top is hot and the bottom is cold, and the middle is overheated while the edges are cool," allowing the bottom surface of the glass to be heated gently and evenly, suppressing internal residual stress, and reducing the risk of warping, hidden cracks, and subsequent spontaneous breakage from the source.

[0017] (iii) The heat treatment processing equipment for the vehicle-mounted special glass cover has multiple sets of flow grooves on the surface of the plate. The hot air in the furnace can penetrate through the grooves from top to bottom. The layered hot air from the temperature control component above covers the upper surface of the glass. The hot air passes through the flow grooves and reaches the lower side of the glass and the heat spreader area, so as to achieve uniform heating of the upper, middle and lower parts of the glass, without dead corners or local hot and cold areas.

[0018] (iv) The heat treatment processing equipment for the vehicle-mounted special glass cover plate has a fixed plate that neatly limits and fixes the two groups of diversion pipes, ensuring that all air outlets are accurately aligned with the area above the vehicle-mounted glass cover plate inside the furnace, ensuring that the hot and cold airflows are directly delivered to the work area without deviation or dispersion. The upper end of the diversion pipe group is connected to the external hot and cold air supply unit, realizing one-click switching and variable frequency adjustment of the hot and cold air sources, and pre-building a complete hot and cold air supply circuit.

[0019] (v) In this vehicle-mounted special glass cover heat treatment equipment, hot air, after being layered and pressurized, is evenly blown out from the lower end of the distribution pipe assembly, covering the upper surface of the glass from top to bottom. Combined with the flow channels of the temperature equalization component below, the hot air penetrates the channels and reaches the bottom of the glass, forming a continuous hot air constant temperature field. This achieves uniform heating and constant temperature preservation, fully releasing the internal stress of the glass. After the annealing furnace heat preservation is completed, low-temperature cold air delivery is switched on. Multi-layered air ducts slowly release air, and the cold air gently covers the glass surface, achieving a gradual and gradual cooling, preventing single-point rapid cooling from generating new internal stress, cracks, and warping.

Detailed Implementation

[0022] Example 1, as Figures 1 to 6 As shown, the present invention provides a technical solution: a heat treatment processing equipment for vehicle-mounted special glass covers, comprising: a frame 1, an annealing furnace 2 fixedly installed on the side of the top of the frame 1, a temperature control component 3 fixedly installed on the top of the annealing furnace 2, sealing doors 4 movably installed on both sides of the outer surface of the annealing furnace 2, and a guide component 5 fixedly installed near the sealing doors 4 of the annealing furnace 2; Temperature uniform component 6 is fixedly installed at the middle of the top of the frame 1 and is located inside the cavity of the annealing furnace 2. Temperature control component 3 is located above temperature uniform component 6. The temperature uniform component 6 includes a base plate 61. A heat spreader 62 and a shim 65 are fixedly installed at the middle of the top of the base plate 61. Adjustment rods 63 are symmetrically installed on both sides of the outer surface of the heat spreader 62. Support members 64 are slidably installed on the surface of the adjustment rods 63. The baffles 642 on both sides of the placement plate 641 form a limiting barrier to prevent the glass from shifting, moving, or slipping when pushed, heated, thermally expanded, or disturbed by airflow. The bottom of the glass is suspended above the placement plate 641, not directly touching the solid surface, leaving space for heat exchange. The heat spreader 62 is centrally located above the base plate 61 and directly below the placement plate 641, continuously and evenly concentrating and conducting the radiant heat from the furnace bottom and the temperature field of the cavity upwards, providing stable auxiliary heating to the bottom surface of the glass and eliminating bottom temperature differences.

[0023] The base plate 61 is fixedly installed at the middle of the top of the frame 1. The shims 65 are set at both ends of the heat spreader 62 and are fixedly installed between opposite surfaces of the inner wall of the annealing furnace 2. The shims 65 are flush with the height of the guide assembly 5 and the support 64. The heat spreader 62 homogenizes the heat energy in the furnace for a second time, forming a flat heat field upwards. This solves the defects of traditional furnaces, such as "hot at the top and cold at the bottom, overheated in the middle and cool at the edges," allowing the bottom surface of the glass to be heated gently and evenly, suppressing internal residual stress, and reducing the risk of warping, hidden cracks, and subsequent spontaneous breakage from the source.

[0024] The support component 64 includes a slide 645, of which two slides 645 are provided. Fixing blocks 644 are fixedly installed on the surfaces of both slides 645. A placement plate 641 is fixedly installed between the opposite surfaces of the fixing blocks 644. Baffles 642 are symmetrically installed on both sides of the outer surface of the placement plate 641. A flow groove 643 is formed on the surface of the placement plate 641. The slide 645 drives the fixing blocks 644 and the placement plate 641 to move synchronously, adjusting the height of the placement plate 641 so that it is flush with the shim blocks 65. This facilitates the subsequent entry of the glass cover plate into the annealing furnace 2. The shim blocks 65 are fixed between the two ends of the heat spreader 62 and the inner wall of the furnace. They are pre-calibrated to the same horizontal height with the guide assembly 5 and the placement plate 641, forming a seamless conveying platform. The glass cover plate, conveyed by the guide rollers 51 of the guide assembly 5, smoothly slides into the furnace along the shim blocks 65 and accurately lands above the placement plates 641 on both sides.

[0025] The slide 645 is movably mounted on the surface of the adjusting bracket 63, and the placement plate 641 is mounted above the heat spreader 62. The vehicle-mounted glass cover is placed above the placement plate 641. Multiple sets of flow grooves 643 are formed on the surface of the placement plate 641, allowing hot air from the furnace to penetrate and flow through the grooves. The layered hot air from the upper temperature control component 3 covers the upper surface of the glass downwards, and the hot air passes through the flow grooves 643 to reach the lower side of the glass and the area of ​​the heat spreader 62, achieving uniform heating of the glass in a fully enclosed manner from top to bottom, without dead corners or local hot and cold areas.

[0026] Example 2, based on Example 1, such as Figures 7 to 9 As shown, the temperature control component 3 includes a top plate 32, a fixing plate 33 is fixedly installed at the bottom of the top plate 32, and a diversion pipe assembly 31 is fixedly installed on the surface of the fixing plate 33. Two sets of diversion pipe assemblies 31 are provided, extending through the fixing plate 33 and the top plate 32 to their exterior. The fixing plate 33 neatly and precisely positions the two sets of diversion pipe assemblies 31, ensuring that all air outlets are accurately aligned with the area above the furnace's onboard glass cover, ensuring that hot and cold airflows are directly delivered to the work area without deviation or dispersion. The upper end of the diversion pipe assembly 31 connects to an external hot and cold air supply unit, enabling one-button switching and variable frequency adjustment of the hot and cold air sources, thus establishing a complete hot and cold air supply circuit in advance.

[0027] The top plate 32 is fixedly installed on the top of the annealing furnace 2, and the diversion pipe assembly 31 is mounted above the vehicle glass cover through the top plate 32. The diversion pipe assembly 31 is connected to the temperature control equipment through a pipeline.

[0028] The distribution pipe assembly 31 includes a connecting pipe 311, with a through rod 312 fixedly installed on the inner wall of the connecting pipe 311. A partition pipe 314 and an inner layer pipe 313 are fixedly installed inside the connecting pipe 311 via the through rod 312. During furnace heating, high-temperature hot air is concentrated and drawn in through the connecting pipe 311. Relying on the internal through rod 312 for reinforcement and separation, the hot air is stably distributed to the multi-layered flow channels formed by the inner layer pipe 313 and the partition pipe 314. The inner layer pipe 313 delivers the main hot air, focusing on heating the central area of ​​the glass. The partition pipe 314 forms an annular auxiliary air duct, supplementing the glass edges with hot air, achieving full-area hot air coverage. The layered and stabilized hot air is evenly blown out from the lower end of the distribution pipe assembly 31, covering the upper surface of the glass from top to bottom. Combined with the flow groove 643 of the lower temperature equalization component 6, the hot air penetrates the groove and reaches the bottom of the glass, forming a continuous hot air constant-temperature field, achieving uniform heating and constant-temperature insulation, and fully releasing the internal stress of the glass.

[0029] The connecting pipe 311 is fixedly installed on the top of the fixed plate 33. The connecting pipe 311, the partition pipe 314, and the inner pipe 313 are configured as a multi-layer structure. During the furnace cooling time, the external unit switches to deliver low-temperature cold air. The cold air is also distributed and stabilized along the multi-layer pipeline, and is delivered smoothly into the furnace to avoid direct cold air blowing or excessive wind speed causing localized sudden cooling. The through rod 312 keeps the multi-layer pipe body coaxial and stable throughout the process, preventing the pipeline from deforming due to thermal expansion and contraction when hot and cold air flows alternately. At the same time, it isolates air leakage in the air duct and ensures that the hot air and cold air have their own independent and unobstructed flow channels. After the annealing furnace 2 has completed its heat preservation, the low-temperature cold air delivery is switched. The multi-layer air duct slowly releases air, and the cold air gently covers the glass plate surface to achieve gradient and slow cooling, preventing single-point rapid cooling from causing new internal stress, cracks, and warping.

[0030] Example 2, based on Examples 1 and 2, such as Figures 2 to 3As shown, the guiding assembly 5 includes a mounting base 53, and two sets of mounting bases 53 are provided. An inclined frame 52 is fixedly installed on the top of each set of mounting bases 53, and a guide roller 51 is rotatably installed between the opposite surfaces of the inclined frame 52. Before starting the equipment, the operator places the special vehicle-mounted glass cover to be heat-treated on the upper end of the inclined frame 52 of the feed-side guide assembly 5 of the annealing furnace 2, so that the bottom of the glass cover is in contact with the surface of the guide roller 51. After receiving the start signal from the equipment control system, the guide roller 51 rotates at a constant speed along its own axis, using rolling friction to drive the glass cover to slide downward along the inclined direction of the inclined frame 52 and move towards the inside of the annealing furnace 2. After the glass cover is conveyed to the lower end of the inclined frame 52 by the guide roller 51, it is aligned with the height of the shim block 65 of the temperature equalization assembly 6. The guide roller 51 continues to rotate, smoothly moving the glass cover to the surface of the shim block 65. After the shim block 65 receives the glass cover, it further guides it to the temperature equalization assembly 6. At this time, the glass cover is completely in the support range of the temperature equalization assembly 6, completing the precise positioning inside the furnace. During the conveying process, the tilting frame 52 and the raised block 65 form a seamlessly connected conveying plane, and the rolling thrust of the guide roller 51 continuously acts on the glass cover plate to ensure that it enters the core processing area of ​​the furnace cavity without deviation or collision.

[0031] The mounting base 53 is fixedly installed on both sides of the annealing furnace 2. The tilting frame 52, the shim block 65, and the placement plate 641 are set at the same height. The tilting frame 52 and the shim block 65 cooperate to guide the vehicle-mounted glass cover plate. After the vehicle-mounted special glass cover plate completes the uniform temperature heat treatment in the furnace, the equipment control system triggers the discharge command. The sealing door 4 on the discharge side of the annealing furnace 2 opens, and at the same time, the guide roller 51 of the discharge side guide assembly 5 rotates in the opposite direction. The rotating guide roller 51 cooperates with the placement plate 641 and the shim block 65 to smoothly guide the glass cover plate from the support member 64 of the uniform temperature assembly 6. The glass cover plate moves along the surface of the shim block 65 towards the upper end of the tilting frame 52. The glass cover plate slides upward along the tilting direction of the tilting frame 52. The guide roller 51 continuously provides rolling support, reducing the friction between the glass and the tilting frame 52 and avoiding scratches or damage to the surface of the glass cover plate.

[0032] During use, before starting the equipment, the operator places the special vehicle-mounted glass cover to be heat-treated on the upper end of the inclined frame 52 of the feed-side guide assembly 5 of the annealing furnace 2, so that the bottom of the glass cover is in contact with the surface of the guide roller 51. After receiving the start signal from the equipment control system, the guide roller 51 rotates at a constant speed along its own axis, using rolling friction to drive the glass cover to slide downward along the inclined direction of the inclined frame 52 and move towards the inside of the annealing furnace 2. After the glass cover is conveyed to the lower end of the inclined frame 52 by the guide roller 51, it is aligned with the height of the shim block 65 of the temperature equalization assembly 6. The guide roller 51 continues to rotate, smoothly moving the glass cover to the surface of the shim block 65. After the shim block 65 receives the glass cover, it further guides it to the temperature equalization assembly 6. At this time, the glass cover is completely in the support range of the temperature equalization assembly 6, completing the precise positioning inside the furnace. During the conveying process, the tilting frame 52 and the raised block 65 form a seamlessly connected conveying plane, and the rolling thrust of the guide roller 51 continuously acts on the glass cover plate to ensure that it enters the core processing area of ​​the furnace cavity without deviation or collision.

[0033] After the special glass cover plate on the vehicle completes the uniform heat treatment in the furnace, the equipment control system triggers the discharge command. The sealing door 4 on the discharge side of the annealing furnace 2 opens, and at the same time, the guide roller 51 of the discharge side guide assembly 5 rotates in the opposite direction. The rotating guide roller 51 cooperates with the placement plate 641 and the shim block 65 to smoothly guide the glass cover plate from the support 64 of the uniform temperature assembly 6. The glass cover plate moves along the surface of the shim block 65 to the upper end of the tilting frame 52. The glass cover plate slides upward along the tilting direction of the tilting frame 52. The guide roller 51 continuously provides rolling support, reducing the friction between the glass and the tilting frame 52 and preventing scratches or damage to the surface of the glass cover plate.

[0034] The slide 645 drives the fixed block 644 and the placement plate 641 to move synchronously, adjusting the height of the placement plate 641 so that the placement plate 641 is flush with the shim block 65, so that the glass cover can enter the annealing furnace 2 later. The shim block 65 is fixed between the two ends of the heat spreader 62 and the inner wall of the furnace. It is pre-calibrated with the guide assembly 5 and the placement plate 641 to the same horizontal height to form a seamless conveying platform. The glass cover, which is conveyed by the guide roller 51 of the guide assembly 5, slides smoothly into the furnace along the shim block 65 and lands precisely on the placement plates 641 on both sides.

[0035] The baffles 642 on both sides of the placement plate 641 form a limiting barrier to prevent the glass from shifting, moving, or slipping when it is pushed, heated, thermally expanded, or disturbed by airflow. The bottom of the glass is suspended above the placement plate 641 and does not directly touch the solid surface, leaving space for heat exchange. The heat spreader 62 is centrally located above the base plate 61 and directly below the placement plate 641, continuously and evenly gathering the radiant heat from the furnace bottom and the temperature field of the cavity and conducting it upwards to provide stable auxiliary heating for the bottom surface of the glass and eliminate the bottom temperature difference.

[0036] The heat spreader plate 62 homogenizes the heat energy inside the furnace a second time, forming a flat heat field upwards. This solves the defects of traditional furnace bodies, such as "hot at the top and cold at the bottom, overheated in the middle and cool at the edges". It allows the bottom surface of the glass to be heated gently and evenly, suppresses internal residual stress, and reduces the risk of warping, hidden cracks and subsequent spontaneous breakage from the source.

[0037] Multiple sets of flow grooves 643 are opened on the surface of the placement plate 641. The hot air in the furnace can penetrate and pass through the grooves from top to bottom. The layered hot air of the temperature control component 3 above covers the upper surface of the glass downwards. The hot air passes through the flow grooves 643 and reaches the lower side of the glass and the area of ​​the heat spreader 62, so as to achieve uniform heating of the upper, middle and lower parts of the glass, without dead corners or local hot and cold areas.

[0038] The fixing plate 33 neatly and precisely limits and fixes the two groups of diversion pipe groups 31, ensuring that all air outlets are accurately aligned with the area above the vehicle-mounted glass cover inside the furnace, ensuring that the hot and cold airflows are directly delivered to the work area without deviation or dispersion. The upper end of the diversion pipe group 31 is connected to the external hot and cold air supply unit, realizing one-button switching and variable frequency adjustment of the two air sources of hot and cold air, and pre-building a complete hot and cold air supply circuit.

[0039] During furnace heating, high-temperature hot air is concentrated and drawn in through the connecting pipe 311. Reinforced and separated by the internal through-rod 312, the hot air is stably distributed to the multi-layered flow channels formed by the inner pipe 313 and the separating pipe 314. The inner pipe 313 delivers the main hot air, focusing on heating the central area of ​​the glass. The separating pipe 314 forms an annular auxiliary air duct, supplementing the glass edges with hot air, achieving full-area hot air coverage. The layered and pressure-stabilized hot air is evenly blown out from the lower end of the distribution pipe assembly 31, covering the upper surface of the glass from top to bottom. Combined with the flow groove 643 of the lower temperature equalization component 6, the hot air penetrates the groove and reaches the bottom of the glass, forming a continuous hot air constant-temperature field. This achieves uniform heating and constant-temperature insulation, fully releasing the internal stress of the glass.

[0040] During the furnace cooling process, the external unit switches to supply low-temperature cold air. The cold air is also distributed and stabilized along multiple layers of pipelines, and then gently delivered into the furnace to avoid direct cold air blowing or excessive wind speed causing localized sudden cooling. The through rod 312 maintains the coaxial stability of the multiple layers of pipes throughout the process, preventing deformation of the pipelines due to thermal expansion and contraction during the alternation of hot and cold airflows. At the same time, it isolates air leakage in the air ducts, ensuring that the hot and cold air flows independently and unobstructed. After the annealing furnace 2 has completed its heat preservation process, the low-temperature cold air supply is switched on. The air is slowly released through multiple layers of air ducts, and the cold air gently covers the glass plate surface, achieving a gradual and slow cooling process and preventing single-point rapid cooling from causing new internal stress, cracks, and warping.
