Description

Technical Field

[0001] This application relates to the technical field of automotive glass deep processing equipment, and in particular to a fully tempered cooling device for automotive glass. Background Technology

[0002] Automotive glass, as a type of glass with high demand in the current market, can be divided into fully tempered glass and zone-tempered glass according to the degree of tempering; and according to the installation position of the glass, it can be divided into windshield glass, side window glass, rear windshield glass and sunroof glass.

[0003] The manufacturing process of automotive glass typically includes loading, heating, bending, pressing, strengthening, cooling, and unloading. First, flat glass of a specific shape is placed on the loading section and conveyed by loading rollers to a continuous heating furnace for heating and softening. The softened, hot glass is then conveyed to the bending section, where it undergoes gradual bending via a bending roller assembly. Next, it is transported via a support structure to the pressing molds, where it is pressed and shaped by upper and lower pressing molds while still heated to meet specific curvature requirements. If tempering is required, the glass undergoes air cooling in the strengthening section to achieve full or partial tempering. It is then conveyed to a cooling section composed of upper and lower cooling fans to cool the glass to a temperature that is comfortable to touch before finally being conveyed out for unloading and storage. However, existing cooling and tempering equipment uses integrated upper and lower air grille units, meaning the curvature of the cooling area formed by the upper and lower air grilles is not adjustable. When processing automotive glass with different specifications, it is often necessary to purchase cooling and tempering equipment with different curvatures, significantly increasing production costs and reflecting the limited applicability of existing equipment. Meanwhile, existing equipment also suffers from uneven cooling and processing, resulting in automotive glass tempering quality failing to meet market demands.

[0004] Regarding the aforementioned technologies, the applicant believes that it is particularly crucial to develop and design a processing equipment that can adjust the arc state of the upper and lower air grille assemblies to adapt to automotive glass with different curvature specifications, and can also perform comprehensive and uniform cooling of automotive glass. Utility Model Content

[0005] In order to enable the cooling device of automotive glass to adjust the cooling curvature of the upper and lower air grilles according to the different curvature specifications of automotive glass during the cooling and tempering process, thereby expanding the applicability of the device and improving the cooling uniformity during the cooling and tempering process of automotive glass, this application provides a fully tempered cooling device for automotive glass.

[0006] The technical solution of the fully tempered cooling device for automotive glass provided in this application is as follows: A fully tempered cooling device for automotive glass includes a support frame, a cooling mechanism for cooling tempered automotive glass, and a conveyor frame for fixing and supporting the automotive glass. The cooling mechanism is mounted on the support frame, and the conveyor frame is slidably connected to the support frame. The cooling mechanism includes an upper air grille group composed of multiple upper air grilles and a lower air grille group composed of multiple lower air grilles. The conveyor frame transports the automotive glass between the upper air grille group and the lower air grille group for cooling and tempering. It also includes a height adjustment component for controlling the raising and lowering of the upper air grating group; a horizontal adjustment component for controlling the reciprocating sliding of the upper air grating group and the lower air grating group; and an angle adjustment component for controlling the bending and arcing of the upper air grating group and the lower air grating group; and the height adjustment component, the horizontal adjustment component and the angle adjustment component are all mounted on the support frame.

[0007] By adopting the above technical solution, the support frame serves as the basic framework of this equipment, housing various functional processing components / parts. A structure employing an upper and lower air grille assembly works in conjunction to provide stable and uniform air-cooled tempering processing. The conveyor rack supporting the automotive glass stably transports it to the cooling zone formed between the upper and lower air grille assemblies, and can even perform reciprocating cooling swaying motions with the glass to improve the cooling uniformity of the upper and lower surfaces. This device installs three types of adjustment components on the support frame for horizontal, height, and arc angle control of the upper and lower air grille assemblies, achieving a more uniform and comprehensive cooling tempering effect, thereby improving the tempering quality of the automotive glass. Specifically, the height adjustment component directly changes the height range between the upper and lower air grille assemblies to match the wind pressure input by the fan, directly altering the cooling air pressure on the upper and lower surfaces of the automotive glass, thus adapting to the processing of automotive glass of different thicknesses. The horizontal adjustment component drives the upper and lower air grille assemblies to slide horizontally back and forth within the controlled height range of the upper and lower air grille assemblies, without interfering with the automotive glass. Meanwhile, the reciprocating cold swing motion of the conveyor frame forms a cross-cooling process that is perpendicular to each other, further improving the cooling uniformity of the automotive glass; the angle adjustment component can mechanically bend the upper and lower air grille groups according to the specific curvature of the automotive glass to be cooled, so as to form the corresponding curvature of the blowing convex surface and blowing concave surface, thereby greatly expanding the applicability of this device.

[0008] Preferably, the bearing frame is provided with an upper bearing frame and a lower bearing frame, and the angle adjustment component includes an upper angle adjustment component for controlling the bending and arcing of the upper wind grating group, and a lower angle adjustment component for controlling the bending and arcing of the lower wind grating group. The upper angle adjustment assembly includes multiple first screw jacks and multiple first adjusting chain plates. The first adjusting chain plates are respectively fixedly connected to both ends of the upper wind grating along its length. The first adjusting chain plates have multiple concentric first arc-shaped holes. Each first screw jack is connected to the upper support frame. The output end of each first screw jack is provided with multiple bolt and nut structures. The bolts in the bolt and nut structures pass through the first arc-shaped holes on the first adjusting chain plates. The nuts in the bolt and nut structures are threaded to the bolts to fix the first adjusting chain plates. The lower angle adjustment assembly includes multiple second screw jacks and multiple second adjusting chain plates. Each second adjusting chain plate is fixedly connected to both ends of the lower air grating along its length. The second adjusting chain plate has multiple concentric second arc-shaped holes. Each second screw jack is connected to the lower support frame. The output end of each second screw jack is also provided with multiple bolt and nut structures. The bolts in the bolt and nut structures pass through the second arc-shaped holes on the second adjusting chain plates. The nuts in the bolt and nut structures are threaded to the bolts to fix the second adjusting chain plates.

[0009] By adopting the above technical solution, an upper support frame and a lower support frame are installed in the top and bottom areas of the support frame respectively to support the upper and lower mechanical structures, thereby modularizing the cooling and adjustment functions of the device. By symmetrically configuring the angle adjustment components as an upper angle adjustment component for controlling the bending of the upper grille assembly and a lower angle adjustment component for controlling the bending of the lower grille assembly, they cooperate to provide cooling areas with corresponding curvatures for automotive glass with different curvatures. The upper angle adjustment component is a mechanical linkage structure composed of multiple first screw jacks and multiple first adjusting chain plates. It achieves single-point adjustment by fixing a single first adjusting chain plate to a single upper grille, and indirectly achieves arc-changing drive for a single upper grille by connecting a single first screw jack to a single first adjusting chain plate. A stable screw and nut structure between the first screw jack and the first adjusting chain plate allows the output end of the jack to slide and adjust along the arc trajectory limited by the first arc-shaped aperture, so that the upper grille exhibits different tilt angles when the conveying end is at different positions within the arc-shaped aperture. For an upper air vent assembly composed of multiple upper air vents, multiple sets of screw lifters output different strokes, collectively creating different curvatures on the air vent surface, such as single or multiple curves, to meet the cooling and tempering requirements of automotive glass of different sizes. The lower angle adjustment component works similarly.

[0010] Preferably, the first screw jack is slidably connected to the upper support frame, and the sliding direction of the first screw jack is perpendicular to the extension and retraction direction of the output end of the first screw jack; the second screw jack is slidably connected to the lower support frame, and the sliding direction of the second screw jack is perpendicular to the extension and retraction direction of the output end of the second screw jack.

[0011] By adopting the above technical solution, when the upper and lower air grating groups form convex or concave air blowing surfaces respectively through the upper and lower angle adjustment components, due to the different concentration levels of the individual air gratings, such as when the upper air grating group forms a convex air blowing surface and the lower air grating group forms a concave air blowing surface, the adjacent individual air gratings of the upper air grating group appear more densely packed, while the adjacent individual air gratings of the lower air grating group appear more dispersed. Furthermore, by sliding the first screw jack in the upper angle adjustment component onto the upper support frame, and sliding the second screw jack in the lower angle adjustment component onto the lower support frame, the different aggregation states of the angle adjustment components can be satisfied when the upper and lower air gratings present different bending states. This makes the arc angle adjustment process smoother and more precise, further improving the applicability of the device.

[0012] Preferably, the upper / lower air grille includes multiple strip-shaped air blowing boxes, each strip-shaped air blowing box having an air blowing section composed of multiple staggered air blowing holes, the air blowing section facing the car window; the ends of the multiple strip-shaped air blowing boxes in a single upper / lower air grille away from the air blowing section are all fixedly formed into one piece by two front and rear first / second adjusting chain plates; and a connecting strip is provided between each adjacent upper / lower air grille, the connecting strip connecting two adjacent strip-shaped air blowing boxes to connect the upper / lower air grilles to form an upper / lower air grille group.

[0013] By adopting the above technical solution, multiple strip-shaped air-blowing boxes are used to form the basic structure of the upper and lower air grilles via the first and second adjusting chain plates, which increases the stability of the upper and lower air grilles during air cooling. Furthermore, the first and second adjusting chain plates can also form a dispersed structure, narrower at the top and wider at the bottom, from the end of each strip-shaped air-blowing box towards the air-blowing section, thereby expanding the air-blowing coverage area of ​​a single air grille (fan-shaped airflow) and improving the cooling uniformity of the upper and lower surfaces of the automotive glass. The addition of connecting strips between adjacent upper and lower air grilles, combined with the concentrated effect of the first and second adjusting chain plates on the multiple strip-shaped air-blowing boxes, further enhances the integrity of the entire upper and lower air grille assembly during air-cooled tempering, preventing instability such as structural loosening due to improper operation during air pressure or angle adjustment.

[0014] Preferably, a lifting frame is slidably disposed inside the bearing frame, the sliding direction of the lifting frame is the same as the adjustment direction of the height adjustment component, and the lifting frame is connected to the upper bearing frame; The height adjustment assembly includes a first drive unit, a pulley block, and a transmission cable. The first drive unit and the pulley block are mounted on the top of the support frame. The output shaft of the first drive unit is connected to the pulley block. The transmission cable is sleeved on the pulley block, and the ends of the transmission cable are all fixedly connected to the lifting frame. The first drive unit drives the transmission cable through the pulley block to raise and lower the lifting frame.

[0015] By adopting the above technical solution, the height adjustment component is configured as a mechanical linkage structure of a first driving component and a pulley combination transmission cable. This allows the height adjustment component to achieve stable lifting and lowering motion of the lifting frame, the upper support frame, and the upper angle adjustment component and upper air grille assembly loaded on them, all through a stable and controllable transmission mechanism using the pulley system and transmission cable. The height adjustment component directly adjusts the blowing distance of the air-cooled tempered upper air grille assembly to the upper surface of the automotive glass, making it suitable for air-cooled tempering of automotive glass of different thicknesses. Simultaneously, to reduce production costs and the integration difficulty of components, the mechanical structure at the bottom of the device used to adjust the lower air grille assembly is eliminated. Instead, the blowing distance of the lower air grille assembly's airflow to the lower surface of the automotive glass is changed by raising or lowering the conveyor frame.

[0016] Preferably, the horizontal adjustment assembly includes an upper horizontal adjustment assembly for controlling the reciprocating sliding of the upper windshield assembly, and a lower horizontal adjustment assembly for controlling the reciprocating sliding of the lower windshield assembly; The upper leveling component includes a first sliding component and a second driving component. Multiple first sliding components are provided and respectively disposed at the connection points between the lifting frame and the upper support frame. Each first sliding component includes a first slide rail and a first mounting base. The first slide rail is fixedly connected to the top of the upper support frame, and the first mounting base is fixedly connected to the bottom of the lifting frame, with the first mounting base slidably connected to the first slide rail. The second driving component includes a second driving member, a first rocker arm, and a first reducer. The first reducer is fixedly connected to the top of the upper support frame, the output shaft of the second driving member is connected to the input end of the first reducer, one end of the first rocker arm is connected to the output end of the first reducer, and the other end of the first rocker arm is connected to the lifting frame. The lower horizontal adjustment assembly includes a second sliding assembly and a third drive assembly. Multiple second sliding assemblies are provided and respectively disposed at the connection points between the support frame and the lower support frame. Each second sliding assembly includes a second slide rail and a second mounting base. The second slide rail is fixedly connected to the bottom of the lower support frame, and the second mounting base is fixedly connected to the support frame and slidably connected to the second slide rail. The third drive assembly includes a third drive member, a second rocker arm, and a second reducer. The second reducer is fixedly connected to the bottom of the lower support frame, the output shaft of the third drive member is connected to the input end of the second reducer, one end of the second rocker arm is connected to the output end of the second reducer, and the other end of the second rocker arm is connected to the support frame.

[0017] By adopting the above technical solution, upper and lower horizontal adjustment components are symmetrically arranged for both the upper and lower windshield groups to control their synchronous horizontal reciprocating movement. The upper horizontal adjustment component is configured as a cooperative structure consisting of a first sliding component and a second driving component. The first sliding component mainly restricts the horizontal sliding path of the upper windshield group, while the second driving component provides the power for horizontal sliding. Specifically, the first sliding component is configured as a mechanical linkage structure consisting of a first slide rail and a first mounting base. The first slide rail is fixed to the upper support frame, and the first mounting base is fixed to the lifting frame, thus initially establishing a sliding connection between the upper support frame and the lifting frame. This indirectly constructs the translational sliding relationship between the upper windshield group and the upper angle adjustment component, which are indirectly loaded on the lifting frame, relative to the overall support frame. Furthermore, the multiple sliding rail structure ensures high stability of the upper grille assembly during horizontal reciprocating sliding. The second drive assembly is configured as a mechanical linkage structure of a second drive element, a first rocker arm, and a first reducer. This allows the second drive element to directly drive the first reducer, which, while controlling the speed ratio, also changes the output direction of the second drive element. The first rocker arm converts rotational motion into horizontal reciprocating motion. The output end of the first rocker arm continuously abuts against and maintains a fixed lifting frame (actually the entire load-bearing frame), thus driving the upper load-bearing frame and its load components to perform horizontal reciprocating motion, thereby improving the cooling uniformity of the automotive glass. Since the upper structure of this device has an additional height adjustment component compared to the lower structure, the upper horizontal adjustment component's operating carrier is actually the lifting frame, which differs from the lower horizontal adjustment component. The same applies to the lower horizontal adjustment component.

[0018] Preferably, the conveyor also drives the car glass to perform reciprocating translational motion, and the horizontal adjustment component controls the sliding direction of the upper air grille group and the lower air grille group to be perpendicular to the translational direction of the conveyor.

[0019] By adopting the above technical solution, the direction of horizontal sliding of the upper and lower air grilles controlled by the horizontal adjustment component is set to be perpendicular to the direction of horizontal sliding of the conveyor frame. This achieves the maximum vertical airflow interference effect, thereby ensuring a good cooling airflow quenching effect at all positions on the upper and lower surfaces of the automotive glass, and further improving the tempering quality of the automotive glass.

[0020] Preferably, the upper grille assembly and the lower grille assembly form a cooling chamber for cooling and tempering the automotive glass, and the distance between the upper grille assembly and the lower grille assembly is set to 60-120 mm.

[0021] By adopting the above technical solution, the distance between the upper and lower air grille assemblies is controlled within the range of 60-120 mm. On the one hand, this ensures cooling intensity and rate. With a specific total air pressure and airflow, adjusting the distance between the upper and lower air grilles and the upper and lower surfaces of the automotive glass significantly increases the speed at which the cooling airflow impacts the glass surface, resulting in a stronger convective heat transfer coefficient. This allows for the instantaneous removal of a large amount of heat from the glass surface. Simultaneously, the high-temperature glass surface cools rapidly, solidifying and hardening quickly, while the interior remains in a high-temperature plastic state. As the interior continues to cool and contract, it generates strong tensile stress on the hardened external surface, while the surface forms corresponding compressive stress, thus ensuring the tempering quality and mechanical strength (impact resistance, bending resistance, etc.) of the automotive glass. On the other hand, it also ensures uniform cooling, reducing deformation and optical distortion. The reasonable spacing allows the airflow, after exiting the nozzle, to reach all parts of the glass almost simultaneously and without attenuation. When the distance between the upper and lower air grilles is less than 60 mm, the car glass is very prone to interference under the joint adjustment of the conveyor and the leveling component, which can lead to scratches on the glass surface. When the distance between the upper and lower air grilles is greater than 120 mm, problems such as airflow diffusion and uneven pressure are likely to occur due to the excessive distance.

[0022] Preferably, the spacing between adjacent upper / lower air grilles is set to 40-50 mm, the diameter of the air holes on the strip-shaped air box is 7-8 mm, and the center distance between adjacent air holes on the strip-shaped air box is 38-40 mm.

[0023] By adopting the above technical solution, the spacing between adjacent upper / lower air grilles is controlled at 40-50 mm, and the center distance between the air holes on adjacent strip-shaped air boxes is controlled at 38-40 mm. This close arrangement ensures a continuous and uniform cooling airflow distribution area on the upper and lower surfaces of the glass, even when the upper / lower air grilles bend. This results in uniform stress distribution on the glass surface and consistent cooling intensity. Controlling the diameter of the air holes on adjacent strip-shaped air boxes to 7-8 mm ensures that the airflow jet has sufficient rigidity and momentum under system air pressure, effectively penetrating the stagnant air layer generated by high temperature on the glass surface, achieving efficient heat exchange and improving the cooling tempering efficiency of automotive glass. When the diameter of the air holes is too large, turbulence interference is easily generated when adjacent airflows merge, affecting cooling uniformity; when the diameter of the air holes is too small, the cooling airflow easily diffuses and attenuates, leading to poor cooling tempering effect.

[0024] Preferably, it also includes an air collection box for providing cooling airflow, wherein multiple air collection pipes are connected to the side of the upper / lower air grille away from the air blowing part, and each air collection pipe is connected to the air collection box by a flexible hose.

[0025] By adopting the above technical solution, an air delivery structure with a collection pipe and a flexible hose connected to the upper and lower air grilles can directly and efficiently blow the cooling airflow output from the collection box to the upper and lower surfaces of the car glass through the blower, reducing airflow loss during the delivery process and thus improving the energy efficiency of the device.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application utilizes a structure where the upper and lower air grilles work together to provide stable and uniform air-cooled tempering processing. The conveyor frame supporting the automotive glass stably transports it to the cooling zone formed between the upper and lower air grille assemblies, and can even perform reciprocating cooling swaying motions with the glass to improve the cooling uniformity of the upper and lower surfaces. This device is equipped with three types of adjustment components on the support frame for horizontal, height, and arc angle control of the upper and lower air grille assemblies, achieving a more uniform and comprehensive cooling tempering effect, thereby improving the tempering quality of the automotive glass. Specifically, the height adjustment component can directly change the height range between the upper and lower air grille assemblies to match the wind pressure input by the fan, directly changing the cooling air pressure on the upper and lower surfaces of the automotive glass, thus making it suitable for processing automotive glass of different thicknesses; the horizontal adjustment component can drive the upper and lower air grille assemblies to slide horizontally back and forth within the controlled height range of the upper and lower air grille assemblies without interfering with the automotive glass. Meanwhile, in conjunction with the reciprocating cold swing motion of the conveyor frame, a cross-cooling process with mutual perpendicularity is formed, further improving the cooling uniformity of the automotive glass; the angle adjustment component can mechanically bend the upper and lower air grille groups according to the specific curvature of the automotive glass to be cooled, so as to form the corresponding curvature of the blowing convex surface and blowing concave surface, thereby greatly improving the applicability of this device. 2. This application symmetrically configures the angle adjustment components into an upper angle adjustment component for controlling the bending of the upper grille assembly and a lower angle adjustment component for controlling the bending of the lower grille assembly. These components work together to provide cooling areas with corresponding curvatures for automotive glass with different curvatures. The upper angle adjustment component is a mechanically linked structure consisting of multiple first screw jacks and multiple first adjusting chain plates. It achieves single-point adjustment by fixing a single first adjusting chain plate to a single upper grille, and indirectly achieves arc-changing drive for a single upper grille by connecting a single first screw jack to a single first adjusting chain plate. A stable screw and nut structure between the first screw jack and the first adjusting chain plate allows the output end of the jack to slide and adjust along the arc trajectory limited by the first arc-shaped aperture. Therefore, when the conveying end is positioned at different positions within the arc-shaped aperture, the upper grille exhibits different tilt angles. For an upper air vent assembly composed of multiple upper air vents, multiple sets of screw lifts output different strokes, which together form different curvatures on the air vent surface of the upper air vent assembly, such as single curves or multiple curves, thereby meeting the cooling and tempering requirements of automotive glass of different sizes and specifications. 3. This application configures the upper horizontal adjustment component as a cooperative structure consisting of a first sliding component and a second driving component. The first sliding component primarily restricts the horizontal sliding path of the upper air grating assembly, while the second driving component provides the power for the horizontal sliding. Specifically, the first sliding component is configured as a mechanical linkage structure consisting of a first slide rail and a first mounting base. The first slide rail is fixed to the upper support frame, and the first mounting base is fixed to the lifting frame, thus initially establishing a sliding connection between the upper support frame and the lifting frame. This indirectly constructs a translational sliding relationship between the upper air grating assembly and the upper angle adjustment component, which are indirectly loaded on the lifting frame, relative to the overall support frame. Furthermore, the multiple sliding rail structure ensures that the upper grille assembly maintains high stability during horizontal reciprocating sliding. The second drive assembly is configured as a mechanical linkage structure of the second drive member, the first rocker arm, and the first reducer. This is intended to directly drive the first reducer through the second drive member. The first reducer can control the speed ratio and change the output direction of the second drive member. The first rocker arm can convert rotational motion into horizontal reciprocating motion. The output end of the first rocker arm continuously abuts against and maintains a fixed lifting frame (actually the entire load-bearing frame), thereby driving the upper load-bearing frame and its load components to perform horizontal reciprocating motion together, thus improving the cooling uniformity of the automotive glass.

[0038] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0039] This application discloses a fully tempered cooling device for automotive glass. (See also...) Figure 1 and Figure 2 The device includes a support frame 1, a cooling mechanism 2 for cooling tempered automotive glass, and a conveyor frame (not shown in the figure) for fixing the automotive glass. The support frame 1 serves as the basic framework structure of this device, and its specific shape is not particularly limited, as long as it can support the various functional mechanisms, components, and parts, and reasonably complete the cooling and tempering process. In this embodiment, the support frame 1 is selected to be similar to a cuboid, and the length and width directions of the support frame 1 are both horizontal. The conveyor frame is not actually a substructure of this device. The conveyor frame is actually a carrier for transporting automotive glass at different processing stages to different processing sections. For example, after the high-temperature automotive glass is heated and softened in the high-temperature continuous furnace, it is gradually shaped into a preliminary form by flat rollers and inclined rollers. Then, it is fixed by the conveyor frame and transported to the pressing section for heating and pressing. Then, it is fixed by the conveyor frame and transported to this device for air-cooling and tempering. The conveyor frame actually slides and transmits on the basic framework of the entire automotive glass production line through mechanical structures (such as slide rails). Therefore, it also maintains a sliding transmission relationship at the section of this device (the conveyor frame structure refers to the existing technology, such as the support frame structure, which supports and fixes the four edges of the automotive glass, and is not the focus of protection of this application).

[0040] Reference Figure 1 and Figure 3The cooling mechanism 2 is mounted and loaded on the support frame 1. The cooling mechanism 2 includes an upper grille group 21 composed of multiple upper grilles and a lower grille group 22 composed of multiple lower grilles. The automotive glass, having completed the previous pressing stage, is transported via a conveyor frame to the area between the upper grille group 21 and the lower grille group 22 for cooling and tempering. To allow for more flexible and adaptable adjustments to the upper grille group 21 and the lower grille group 22 to accommodate different sizes of automotive glass and various processing requirements, the device also includes a height adjustment component 3 for controlling the raising and lowering of the upper grille group 21; a horizontal adjustment component 4 for controlling the reciprocating sliding of the upper grille group 21 and the lower grille group 22; and an angle adjustment component 5 for controlling the bending and curvature of the upper grille group 21 and the lower grille group 22. All three types of adjustment components are also mounted and loaded on the support frame 1. Meanwhile, in order to enable various adjustment components to more clearly adjust the upper windshield assembly 21 and the lower windshield assembly 22, the upper support frame 1 and the lower support frame 1, which are of smaller size, are also slidably connected inside the support frame 1 according to their structural characteristics. The upper support frame 11 is indirectly connected to the upper windshield assembly 21, while the lower support frame 12 is indirectly connected to the lower windshield assembly 22. The length and width directions of the upper / lower support frames 12 are consistent with the length and width directions of the support frame 1.

[0041] Reference Figure 3 and Figure 4 The angle adjustment component 5 includes an upper angle adjustment component 51 for controlling the bending and arcing of the upper windshield assembly 21, and a lower angle adjustment component 52 for controlling the bending and arcing of the lower windshield assembly 22. The upper angle adjustment component 51 includes multiple first screw jacks 511 and multiple first adjusting chain plates 512. In this embodiment, the first adjusting chain plates 512 are square sheet structures, and the connection between the first adjusting chain plates 512 and the upper windshield is such that two first adjusting chain plates 512 are respectively installed at both ends of a single upper windshield along its length direction. Specifically, a detachable connection can be constructed using bolts and nuts. Furthermore, to achieve better bending between adjacent upper windshields without interference, the adjacent first adjusting chain plates 512 corresponding to adjacent upper windshields can be arranged in a front-to-back relationship, so that during bending, adjacent first adjusting chain plates 512 approach and intersect, but do not directly collide. Meanwhile, each of the first adjusting chain plates 512 is provided with multiple (the number of which is set to n) first arc-shaped holes 5121 with the same center, where n≥2; and the center of the first arc-shaped holes 5121 on each of the first adjusting chain plates 512 faces the upper wind grille downward. In this embodiment, the first adjusting chain plate 512 is specifically provided with two first arc-shaped holes 5121, and the arc length of the upper first arc-shaped hole 5121 is slightly longer than the arc length of the lower first arc-shaped hole 5121.

[0042] Multiple first screw jacks 511 are provided, and the number of first screw jacks 511 is the same as the number of first adjusting chain plates 512. Each first screw jack 511 is slidably connected to the upper support frame 11 (using a reasonable structure such as a slide rail + mounting base in the prior art; to ensure sliding stability, it can be set as two sliding mounting points with appropriate spacing). The sliding direction is set along the length direction of the support frame 1, while the pushing / retracting direction of the first screw jack 511 is set along the height direction of the support frame 1. The output end of each first screw jack 511 is set downward and has an independent connection relationship with each first adjusting chain plate 512. Specifically, the output end of the first screw jack 511 is equipped with two bolt and nut structures. A single bolt passes through the corresponding first arc-shaped hole 5121, and the first adjusting chain plate 512 is fixed to the output end of the first screw jack 511 by the nut thread connection bolt, and the upper wind grid below is presented at different angles through the first arc-shaped hole 5121. Furthermore, by coordinating the different advance or retraction strokes of each first screw jack, the upper air grating assembly 21 can be constructed with a single curved surface or even multiple curved surfaces. Similarly, the lower angle adjustment assembly 52 includes multiple second screw jacks 521 and multiple second adjusting chain plates 522 (and second arc-shaped apertures 5221 thereon), and constructs the lower air grating assembly 22 with a single curved surface or even multiple curved surfaces in the same manner as the upper angle adjustment assembly 51, but the upper angle adjustment assembly 51 and the lower angle adjustment assembly 52 are arranged in a mirror-symmetrical configuration. The angle adjustment can be performed manually or by electronic program control.

[0043] Reference Figure 3The specific structures of the upper and lower air vents can be further divided. In this embodiment, the upper / lower air vents include multiple strip-shaped air boxes 23, with the length of each strip-shaped air box 23 arranged along the width of the support frame 1. Each strip-shaped air box 23 is provided with a blowing section for blowing cooling airflow. The blowing section is composed of multiple staggered air holes, and the arrangement of the air holes is not specifically limited, as long as uniform and efficient air delivery can be achieved. The air blowing sections of the multiple strip-shaped air boxes 23 in a single upper air vent are located at the bottom and face the upper surface of the car glass. The side of the multiple strip-shaped air boxes 23 in a single upper air vent away from the air blowing section and the two ends along their own length direction are fixed into one piece by two first adjustment links. In order to maintain a reasonable blowing surface and maintain the maximum area, a single upper air vent group 21 can present a fan-shaped arrangement that is narrower at the top and wider at the bottom. A connecting strip 24 can be installed between two adjacent upper air grilles. In this embodiment, the connecting strip 24 is a hollow strip structure, with its two ends connected to the leftmost and rightmost strip air grilles of the adjacent upper air grilles, respectively. The connection point can be achieved using a detachable bolt and nut structure, thereby improving the stability and integrity of the upper air grille when blowing cooling airflow. The lower air grille also adopts the same structure, and is arranged in a mirror image symmetrical arrangement relative to the upper air grille. However, in terms of arrangement (when the car glass is curved), the lower end face of the upper air grille group 21 presents a convex air grille surface that matches the concave surface of the car glass, and the upper end face of the lower air grille group 22 presents a concave air grille surface that matches the convex surface of the car glass (the opposite is true for a reverse curve). At the same time, when the upper and lower air grilles are flat, the air blowing holes on the upper air grille group 21 correspond vertically to the air blowing holes on the lower air grille group 22.

[0044] Meanwhile, the cooling airflow source for this device also requires an external air collection box (not shown in the figure). In each upper / lower air grille, the middle of the strip-shaped air box 23 on the side away from the air blowing section is also connected to multiple air collection pipes 25. In this embodiment, the air collection pipes 25 are set as funnel-shaped. The funnel opening of the air collection pipes 25 is connected to the air collection box through a flexible hose (not shown in the figure) to stably and continuously deliver the cooling airflow generated in the air collection box to the upper and lower air grille groups 22, and then blown to the upper and lower surfaces of the automotive glass through multiple sets of air blowing holes on the air blowing section of the strip-shaped air box 23 for cooling and tempering.

[0045] Reference Figure 2 and Figure 3Inside the upper part of the support frame 1, a lifting frame 13 is slidably installed (also using a conventional structure of slide rail + mounting base). The length and width directions of the lifting frame 13 are consistent with the length and width directions of the support frame 1. The sliding direction between the lifting frame 13 and the support frame 1 is set along the height direction of the support frame 1. The lifting frame 13 is located at the upper end of the upper support frame 11 and connected to it. In fact, the lifting frame 13 is a transition structure between the upper support frame 11 and the height adjustment component 3 to establish an indirect connection. The height adjustment component 3 is designed to adjust the lifting height of the upper air grille group 21, while the lower air grille group 22 maintains a specific height. The height of the cooling area between the upper and lower air grille groups 22 is relatively changed by its adjustment. The height adjustment component 3 includes a first drive member 31, a pulley group 32, and a transmission cable 33. In this embodiment, the first drive member 31 can be a motor and a cylinder (which also bears the counterweight) working together. The motor and the cylinder are both installed on the top of the support frame 1 and are symmetrically arranged to maintain uniform lifting. Furthermore, the power output of the first driving component 31 can be synchronously transmitted to the pulley groups 32 at both ends through a transmission structure (such as a drive shaft). Multiple pulley groups 32 are symmetrically arranged and distributed on the top of the support frame 1. Multiple transmission cables 33 (which can be chains, etc.) are also set according to the number of pulley groups 32. Their ends are fixedly connected to the four vertices of the lifting frame 13. The first driving component 31 is used to lift or lower the lifting frame 13, as well as the upper support frame 11, the upper angle adjustment component 51, and the upper air grid group 21 at the bottom of the lifting frame 13.

[0046] Reference Figure 3 and Figure 5 The horizontal adjustment component 4 includes an upper horizontal adjustment component 41 for controlling the reciprocating sliding of the upper windshield assembly 21, and a lower horizontal adjustment component 42 for controlling the reciprocating sliding of the lower windshield assembly 22. Specifically, the upper horizontal adjustment component 41 includes a first sliding component 411 and a second driving component 412. The first sliding component 411 is mainly used to limit the sliding trajectory of the upper windshield assembly 21, while the second driving component 412 is mainly used to provide the power to drive the upper windshield assembly 21 to slide. In this embodiment, four first sliding components 411 are provided, respectively located on the frame bars of the lifting frame 13 near its four vertices along the length direction. The sliding connection between the lifting frame 13 and the upper support frame 11 is constructed through multiple first sliding components 411, and their sliding directions are all set along the length direction of the support frame 1. The first sliding assembly 411 includes a first slide rail 4111 and a first mounting base 4112. Each first slide rail 4111 is fixedly connected to the top of the upper support frame 11, and each first mounting base 4112 is fixedly connected to the bottom of the lifting frame 13. The four first mounting bases 4112 located at the four corners of the lifting frame 13 are correspondingly engaged with the four first slide rails 4111 located at the four corners of the upper support frame 11, and slide smoothly along the direction jointly restricted by the four first slide rails 4111.

[0047] The second drive assembly 412 includes a second drive member 4121, a first rocker arm 4122, and a first reducer 4123. In this embodiment, the first reducer 4123 is located on top of the upper support frame 11, and the first drive member 4121 is selected as a motor. The output end of the first drive member 4121 is connected to the input end of the first reducer 4123, and the output end of a single first reducer 4123 is connected to two first rocker arms 4122 on the same side. One of the first rocker arms 4122 is synchronously connected through a transmission structure (such as a drive shaft). The arm body component of the first rocker arm 4122 can adopt a positive and negative toothed rod connection structure to facilitate length adjustment. One end of the first rocker arm 4122 is connected to the output end of the first reducer 4123 via an arc component and a connecting rod structure, so as to convert the rotation of the first reducer 4123 into a pushing and retracting motion of the arm body and end. The other end of the first rocker arm 4122 is hinged to the lifting frame 13. Two connection points are constructed through the two first rocker arms 4122, and both connection points are located on the frame in the width direction of the lifting frame 13 to obtain a stable reciprocating horizontal swing. Specifically, the motor drives the first reducer 4123 to drive the two first rocker arms 4122 to swing synchronously, and with the cooperation of the four first slide rails 4111 in the same direction, the upper wind grid assembly 21 can be reciprocated along the length direction of the support frame 1. Similarly, the lower horizontal adjustment assembly 42 includes a second sliding assembly 421 and a third drive assembly 422. The second sliding assembly 421 includes a second slide rail 4211 and a second mounting base 4212, and the third drive assembly 422 includes a third drive member 4221, a second rocker arm 4222, and a second reducer 4223. The implementation principle is the same as that of the upper horizontal adjustment assembly 41, and will not be elaborated here.

[0048] Simultaneously, the conveyor also drives the car glass to perform reciprocating translational motion, which can be implemented using existing technology. However, the horizontal adjustment component 4 controls the sliding direction of the upper and lower air grille groups 22 to be perpendicular to the sliding direction of the conveyor. That is, the direction in which the conveyor drives the car glass to slide is set along the width direction of the carrier frame 1, while the direction in which the horizontal adjustment component 4 drives the upper and lower air grille groups 22 to slide is set along the length direction of the carrier frame 1. Furthermore, the spacing between the upper and lower air grille groups 22 is ensured to be sufficient to avoid interference between the car glass and the device structure, causing scratches, etc. Specifically, the spacing between the air grille group and the lower air grille group 22 is set to 60-120 mm, preferably 72-100 mm; and the spacing between the upper and lower air grilles is set to 40-50 mm, preferably 42-48 mm; the diameter of the air holes on the strip-shaped air blowing box 23 is 7-8 mm, preferably 8 mm; and the center distance between the air holes on adjacent strip-shaped air blowing boxes 23 is 38-40 mm, preferably 40 mm.

[0049] The implementation principle of the fully tempered cooling device for automotive glass according to an embodiment of this application is as follows: First, the automotive glass, having completed the previous steps, is transported to this device via a conveyor frame, specifically located in the cooling area formed between the upper and lower air grille assemblies 22. Angle adjustment assembly 5 is used beforehand to adjust the upper and lower air grille assemblies 22 to conform to the curvature of the automotive glass. Then, height adjustment assembly 3 is used to raise or lower the upper air grille assembly 21 to a suitable height. The automotive glass is moved back and forth by the conveyor frame, while the upper and lower air grille assemblies 22 are simultaneously moved left and right by the horizontal adjustment assembly 4, always keeping the automotive glass within the airflow cooling range. Finally, air is blown through the air collection box to perform cooling and tempering processing. After completion, the glass is transported to the next stage via the conveyor frame.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
