Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing control technology, and in particular to an intelligent manufacturing system and method for composite tempered glass. Background Technology

[0002] Tempered glass, also known as reinforced glass, is a glass product that improves the mechanical strength and thermal stability of ordinary glass by performing surface treatments using physical or chemical methods.

[0003] Physically tempered glass has a compressive stress layer formed on its surface. When the glass is subjected to external force, this layer effectively resists the pressure, thus increasing the glass's strength. Chemically tempered glass, on the other hand, is formed by immersion, which alters the surface composition of the glass to create a compressive stress layer. Compared to physically tempered glass, it requires a lower processing temperature and is suitable for thin glass and complex-shaped glass products.

[0004] By using tempered glass as a base and then combining it with other materials, the performance of tempered glass can be effectively improved.

[0005] Chinese Patent Publication No. CN119329141B discloses an impact-resistant laminated glass and its manufacturing process, comprising a first glass layer, a second glass layer, and a composite intermediate layer disposed between the first and second glass layers. The composite intermediate layer includes a stress concentration layer, a stress diffusion layer, and a third glass layer disposed between the stress concentration layer and the stress diffusion layer. The thickness ratio between the stress concentration layer, the third glass layer, and the stress diffusion layer is 0.6–1:1:1–1.5. The second glass layer, as the outer side of the vehicle window, possesses excellent impact resistance with the assistance of the stress diffusion layer. The first glass layer, as the inner side of the vehicle window, with the assistance of the stress concentration layer, allows the laminated glass to be easily broken from inside the vehicle. This ensures vehicle safety while also facilitating self-rescue for drivers and passengers in extreme driving environments, thus protecting passenger safety.

[0006] However, the above method has the following problems: for composite tempered glass with more complex shapes, it is difficult for the composite layer to adhere to the tempered glass itself, and when the tempered glass is broken, the direction of the flying debris is difficult to control, which leads to a reduction in the safety of composite tempered glass. Summary of the Invention

[0007] To address this, the present invention provides a smart manufacturing system and method for composite tempered glass, which overcomes the problems in the prior art where, for tempered glass with complex shapes, the composite layer is difficult to adhere to the tempered glass itself, and the direction of the flying debris is difficult to control when the tempered glass is broken, thus reducing the safety of the composite tempered glass.

[0008] On one hand, the present invention provides a smart manufacturing system for composite tempered glass, comprising:

[0009] The pre-processing unit is used to cut and grind the edges of the glass sheet;

[0010] The heating chamber, connected to the pretreatment mechanism, is used to heat the glass to its softening temperature;

[0011] A bender, installed together with the heating chamber, is used to bend the heated glass.

[0012] The cooling chamber, connected to the heating chamber, is used to cool and temper the bent glass to form tempered glass.

[0013] A control center connected to the bending device and the cooling chamber is used to generate corresponding composite feedback based on the stage appearance and final appearance of the glass layer.

[0014] A shaping device, connected to the bending device, is used to pre-bend the composite layer according to composite feedback;

[0015] Alternatively, the glass layer can be bent a second time based on the composite feedback;

[0016] A bonding chamber, which is connected to the shaping device, is used to bond the composite layer to the glass layer to form composite tempered glass;

[0017] The composite feedback is wherein the shaping device is controlled to pre-bend the composite layer according to the stage appearance, or the shaping device is controlled to perform a secondary bending of the glass layer according to the final appearance.

[0018] Furthermore, the control center is equipped with several bending thresholds corresponding to the pre-bending, used to control the pre-bending of the composite layer.

[0019] The bending threshold is related to the bending amplitude of the glass layer. For a single tempered glass, the corresponding bending threshold is the angle between the normal vectors of the path before bending and the path after bending at the bending point.

[0020] Furthermore, regarding a single bending point of the composite tempered glass,

[0021] If the bending radius of the glass layer exceeds the adaptive bending threshold but does not reach the excessive bending threshold, the control center determines that the composite layer and the glass layer should be bent with reduced bending.

[0022] If the bending radius of the glass layer exceeds the excessive bending threshold, the control center determines that the composite layer should undergo incremental bending.

[0023] Wherein, the adaptive bending threshold is less than the excessive bending threshold.

[0024] The reduced bending is achieved by cold bending the composite layer along the bending direction according to the bending point, and the bending amplitude is not greater than the adaptive bending threshold.

[0025] The incremental bending is a hot bending at the bending point, and the bending amplitude is not less than the excessive bending threshold.

[0026] Furthermore, for composite layers that undergo reduced bending, when they are bonded to the corresponding tempered glass, the bending point is used as a reference for bonding.

[0027] For composite layers that undergo incremental bending, when they are bonded to the corresponding tempered glass, the edge of the tempered glass is used as a reference.

[0028] Furthermore, regarding a single bending point of the composite tempered glass,

[0029] If the bending radius of the glass layer exceeds the limit bending threshold, the control center determines that the glass layer should be bent a second time.

[0030] The secondary bending involves retracting the glass layer into the heating chamber and setting an adhesion mark at the bending point to attach the composite layer.

[0031] Furthermore, for the glass layer that has undergone a second bending, the control center divides the composite layer into several partitions based on the bonding marks, and sets the shape corresponding to the bonding marks according to the bonding marks.

[0032] Furthermore, when the control center controls the bonding chamber to bond the composite film and tempered glass, it bonds the tempered glass according to the edge of the tempered glass or the bonding marks on the tempered glass.

[0033] Furthermore, the preparation system is also equipped with a test chamber for testing the fracture direction of the composite tempered glass.

[0034] Furthermore, the test chamber includes an impact fragmentation chamber and a temperature difference fragmentation chamber, wherein,

[0035] The impact fragmentation chamber is used to test the direction of the composite tempered glass fragments by impacting the edge of the composite tempered glass.

[0036] Thermostatic fracture chamber is used to test the splash direction of the composite tempered glass by heating it at preset cycles.

[0037] On the other hand, the present invention provides a method for preparing a smart composite tempered glass, comprising:

[0038] Bend the original glass sheet and measure the bending radius;

[0039] The database is retrieved based on the bending radius, and the corresponding composite layer is prepared.

[0040] If the bending amplitude does not exceed the excessive bending threshold, the composite layer is subjected to reduced bending.

[0041] If the bending amplitude exceeds the excessive bending threshold, the composite layer is subjected to incremental bending.

[0042] If the bending amplitude exceeds the limit bending threshold, the glass sheet is bent a second time and a corresponding composite layer is prepared.

[0043] Raw glass sheets are used to form tempered glass;

[0044] The composite layer is bonded to tempered glass to form composite tempered glass.

[0045] Compared with the prior art, the beneficial effects of the present invention are that by setting up a control center to dynamically monitor the stage appearance and final appearance of the glass and generate composite feedback, manual intervention is effectively avoided. This not only effectively improves product consistency but also enhances the compatibility between the composite layer and the tempered glass, thereby effectively improving the adhesion between the composite layer and the tempered glass layer. This avoids damage to the composite tempered glass during operation caused by uneven adhesion, thus effectively improving the safety of the composite tempered glass.

[0046] Furthermore, by setting bending points, the tempered glass and the composite film are bent in the same way. At the same time, the bending points themselves are used to set the specific positions for bonding. By taking advantage of the relatively smooth and continuous characteristics of the glass itself, the composite layer and the tempered glass layer are bonded more tightly, thereby effectively improving the thickness consistency of the composite layer and the tempered glass layer when they are bonded in the bending area.

[0047] Furthermore, by reshaping the glass layer with a large bending radius, the overall thickness of the bent portion is increased, thereby improving the structural stability of the tempered glass. At the same time, by setting bonding marks, the tempered glass can more effectively support the discontinuous composite film, avoiding damage to the composite tempered glass during operation due to uneven bonding, thus effectively improving the safety of the composite tempered glass.

[0048] Furthermore, reduced bending (cold bending) is suitable for medium bending requirements, reducing excessive deformation of the composite layer and lowering internal stress after bonding. Incremental bending (hot bending) handles high bending amplitudes, ensuring the deformation synchronization of the composite layer and tempered glass, and avoiding delamination or warping. Intelligent selection of bonding reference (bending point or edge) further optimizes bonding strength, improving optical performance and durability.

[0049] Furthermore, glass exceeding the ultimate bending threshold is processed through a secondary bending mechanism, returning it to the heating chamber for reshaping to avoid waste. Bonding markings and zoned bonding technology support high-precision lamination of multi-bending-point and irregularly shaped glass (such as automotive sunroof glass), adapting to customized needs.

[0052] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0053] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0054] It should be noted that in the description of this invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc., which indicate directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0055] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 this invention according to the specific circumstances.

[0056] Please see Figure 1 As shown, it is a schematic diagram of the intelligent composite tempered glass manufacturing system of the present invention, including:

[0057] The pre-processing unit is used to cut and grind the edges of the glass sheet;

[0058] The heating chamber, connected to the pretreatment mechanism, is used to heat the glass to its softening temperature;

[0059] A bender, installed together with the heating chamber, is used to bend the heated glass.

[0060] The cooling chamber, connected to the heating chamber, is used to cool and temper the bent glass to form tempered glass.

[0061] The control center, connected to the bending machine and cooling chamber, generates corresponding composite feedback based on the stage appearance and final appearance of the glass layer.

[0062] A shaping device, connected to a bending device, is used to pre-bend the composite layer based on composite feedback;

[0063] Alternatively, the glass layer can be bent a second time based on composite feedback;

[0064] The bonding chamber, which is connected to the shaping device, is used to bond the composite layer to the tempered glass to form composite tempered glass;

[0065] Among them, the composite feedback is to pre-bend the composite layer according to the stage appearance control shaper, or to perform a secondary bending of the glass layer according to the final appearance control shaper.

[0066] By using a control center to dynamically monitor the stage and final appearance of the glass and generate composite feedback, manual intervention can be effectively avoided. This not only improves product consistency but also enhances the compatibility between the composite layer and the tempered glass, thereby improving the adhesion between the two layers. This prevents damage to the composite tempered glass during operation caused by uneven adhesion, thus effectively improving the safety of the composite tempered glass.

[0067] In implementation, the above system has the following process:

[0068] 1. Preprocessing stage

[0069] The pre-processing unit automatically cuts the glass sheet (to the size of the skylight) and performs precision edge grinding to ensure that there are no cracks on the edges.

[0070] 2. Heating and initial bending

[0071] The glass is placed in the heating chamber and heated to the softening temperature (approximately 600-700℃).

[0072] The bending machine presses the softened glass into the shape of a skylight (stage appearance inspection).

[0073] 3. Control Center Decision-Making

[0074] The control center scans the bent glass and calculates the angle between the normal vectors at the bending point:

[0075] If the bending angle does not exceed the adaptive bending threshold (e.g., 30°), it will directly enter the cooling chamber for tempering.

[0076] If the bending angle exceeds the excessive bending threshold (e.g., 50°), incremental bending (thermal bending composite layer) is triggered.

[0077] If the bending angle exceeds the limit bending threshold (e.g., 70°), return it to the heating chamber for a second bending and mark the bonding point.

[0078] 4. Composite layer treatment (taking incremental bending as an example)

[0079] The shaping tool heat-bends the PVB composite layer (60°) to make it slightly larger than the curvature of tempered glass (incremental compensation).

[0080] The bonding chamber uses the glass edge as a reference to vacuum press the PVB layer onto the tempered glass.

[0081] 5. Security Testing

[0082] Impact fragmentation chamber: A steel ball impacts the edge of the skylight to ensure that fragments do not scatter (compliant with ECE R43).

[0083] Temperature difference fracture chamber: Cyclic testing from -30℃ to 80℃ verified that there is no risk of spontaneous explosion.

[0084] result

[0085] Ultimately, the sunroof glass combines high strength (tempered layer), impact resistance (PVB composite layer), and safety against breakage, with no optical distortion.

[0086] Specifically, the control center has several bending thresholds corresponding to pre-bending, which are used to control the pre-bending of the composite layer.

[0087] The bending threshold is related to the bending amplitude of the glass layer. For a single glass layer, the corresponding bending threshold is the angle between the normal vectors of the path before bending and the path after bending at the bending point.

[0088] By setting bending points, the glass layer and the composite film are bent in the same way. At the same time, the bending points themselves are used to set the specific positions for bonding. By taking advantage of the relatively smooth and continuous characteristics of the glass itself, the composite layer and the tempered glass layer are bonded more tightly, thereby effectively improving the thickness consistency of the composite layer and the tempered glass layer when they are bonded in the bending area.

[0089] Specifically, for a single bending point of composite tempered glass,

[0090] If the bending radius of the glass layer exceeds the adaptive bending threshold but does not reach the excessive bending threshold, the control center determines that the composite layer and the glass layer should be bent with reduced amount.

[0091] If the bending radius of the glass layer exceeds the excessive bending threshold, the control center determines that the composite layer should undergo incremental bending.

[0092] Among them, the adaptive bending threshold is less than the excessive bending threshold.

[0093] Reduced bending involves cold bending the composite layer along the bending direction based on the bending point, with the bending amplitude not exceeding the adaptive bending threshold.

[0094] Incremental bending is a hot bending at the bending point, and the bending amplitude is not less than the excessive bending threshold.

[0095] Reduced bending (cold bending) is suitable for medium bending requirements, reducing excessive deformation of the composite layer and lowering internal stress after bonding. Incremental bending (hot bending) handles high bending amplitudes, ensuring the composite layer and tempered glass deform synchronously and preventing delamination or warping. Intelligent selection of bonding reference (bending point or edge) further optimizes bonding strength, improving optical performance and durability.

[0096] Example 1:

[0097] Car side window glass

[0098] Bending test:

[0099] After the glass layer is softened in the heating chamber, it is bent into a 25° arc by a bending device (stage appearance scan).

[0100] The control center calculated that 25° > the adaptive bending threshold (20°), but < the excessive bending threshold (40°).

[0101] Reduce bending decision:

[0102] The PVB composite layer is cold-bent, with a bending angle ≤20° (lower than 25° for glass).

[0103] Bonding process:

[0104] The composite layer is bonded with the bending point as the reference, and the elasticity of the PVB material is used to compensate for the 5° curvature difference, thus avoiding stress concentration.

[0105] At this point, the finished glass produced using the above system has a smooth curvature, no optical distortion, and no risk of delamination between the PVB layer and the tempered glass.

[0106] Example 2:

[0107] Building dome glass

[0108] Scenario: Manufacturing glass domes for buildings with large curvature (such as airport skylights).

[0109] Bending test:

[0110] The glass layer is bent into a 55° arc shape (stage appearance scan).

[0111] The control center calculated that 55° is greater than the excessive bending threshold (40°).

[0112] Incremental bending decision:

[0113] The composite layer (such as SGP interlayer) is subjected to hot bending with a bending radius ≥40° (actually processed to 58°).

[0114] Bonding process:

[0115] The composite layer is bonded to the glass edge as a reference, and the 55° bend of the glass is covered by the plastic deformation of hot bending to ensure edge sealing.

[0116] At this point, the dome glass using the above system withstands high wind pressure without delamination, and the thermally bent composite layer provides additional structural strength.

[0117] Specifically, for composite layers that undergo reduced bending, when they are bonded to the corresponding tempered glass, the bending point is used as the reference point for bonding.

[0118] For composite layers that undergo incremental bending, when they are bonded to the corresponding tempered glass, the edge of the tempered glass is used as a reference.

[0119] Specifically, for a single bending point of composite tempered glass,

[0120] If the bending radius of the glass layer exceeds the limit bending threshold, the control center determines that the glass layer should be bent a second time.

[0121] The secondary bending process involves retracting the glass layer into the heating chamber and setting bonding marks at the bending point to attach the composite layer.

[0122] Glass exceeding its bending threshold is processed via a secondary bending mechanism, returning it to the heating chamber for reshaping to prevent waste. Bonding markings and zoned bonding technology support high-precision lamination of multi-bending-point and irregularly shaped glass (such as automotive sunroof glass), adapting to customized needs.

[0123] Example 3: Curved TV Protective Glass

[0124] Glass bending condition:

[0125] The glass layer is bent to form a 30° arc (adaptive bending threshold 25°, excessive bending threshold 45°).

[0126] The control center determined that if the angle is 30° > 25° but < 45°, a reduced bending method should be adopted.

[0127] Composite layer treatment:

[0128] The AG anti-glare composite layer is cold-bent 28° (<30° for glass).

[0129] Vacuum bonding is performed in the bonding chamber, using the bending point as a reference.

[0130] Example 4: Based on Example 1,

[0131] The glass layer is bent up to 50° (excessive bending threshold 40°).

[0132] Control center determines: 50° > 40° → Incremental bending to be adopted.

[0133] Composite layer treatment:

[0134] The PVB interlayer was hot-bent at 52°.

[0135] In the bonding chamber, the four edges of the glass are first aligned, and then hot-pressed together.

[0136] Example 5: Based on Example 2,

[0137] First bend:

[0138] The glass can be bent up to 75° (the ultimate bending threshold is 60°).

[0139] The control center detected a risk of microcracks.

[0140] Secondary bending process:

[0141] Return to the heating chamber and reheat to 650℃

[0142] Laser bonding marks are set at the 60° bend point.

[0143] Bend in two stages: first 40° → cool → then 20°

[0144] Special treatment for composite layers:

[0145] The polycarbonate composite layer is divided into sections according to markings:

[0146] Main viewing area: 3mm thick, high light transmittance

[0147] Edge area: 5mm thick, reinforced structure

[0148] Stepped hot-press bonding is used.

[0149] In particular, for products like automotive panoramic sunroofs that require both large curvature and high strength, the system intelligently combines different processes:

[0150] Main arc area (50°) → Incremental bending

[0151] Transition zone (35°) → Reduced bending

[0152] Drainage channel (65°) → final result after double bend:

[0153] Top stone impact resistance (SAE J400 test)

[0154] Waterproof at the edges (IPX7 rating)

[0155] Weight reduced by 15% (compared to traditional sandwich panels)

[0156] Specifically, for the glass layer that has undergone a second bending, the control center divides the composite layer into several partitions based on the bonding marks, and sets the shape corresponding to the bonding marks according to the bonding marks.

[0157] By reshaping the glass layer with a large bending radius, the overall thickness of the bent portion is increased, thereby improving the structural stability of the glass layer. At the same time, by setting bonding marks, the glass layer can more effectively support the discontinuous composite film, avoiding damage to the composite tempered glass during operation caused by uneven bonding, thus effectively improving the safety of the composite tempered glass.

[0158] Specifically, when the control center controls the bonding chamber to bond the composite film and tempered glass, it bonds the tempered glass according to the edge of the tempered glass or the bonding marks on the tempered glass.

[0159] Specifically, the preparation system also includes a test chamber for testing the fracture direction of the composite tempered glass.

[0160] Specifically, the test chamber includes an impact fragmentation chamber and a thermal fragmentation chamber, among which...

[0161] The impact fragmentation chamber is used to test the direction of glass fragmentation by impacting the edge of the composite tempered glass.

[0162] Thermostatic shattering chamber is used to test the direction of glass shards in composite tempered glass by heating it at preset intervals.

[0163] Please see Figure 2 As shown, it is a flowchart of the intelligent fabrication method for composite tempered glass of the present invention, including:

[0164] Bend the original glass sheet and measure the bending radius;

[0165] The database is retrieved based on the bending radius, and the corresponding composite layer is prepared.

[0166] If the bending amplitude does not exceed the excessive bending threshold, the composite layer is subjected to reduced bending.

[0167] If the bending amplitude exceeds the excessive bending threshold, the composite layer is subjected to incremental bending.

[0168] If the bending amplitude exceeds the limit bending threshold, the glass sheet is bent a second time and a corresponding composite layer is prepared.

[0169] Tempered glass sheet, used to form tempered glass;

[0170] The composite layer is bonded to tempered glass to form composite tempered glass.

[0171] In implementation, the following steps are included for panoramic sunroofs of new energy vehicles:

[0172] 1. Bending and measuring the original glass sheet

[0173] The pretreated glass sheet is placed in the heating chamber and heated to the softening temperature (approximately 680°C).

[0174] The bender presses the glass into an arc shape (target bending angle: 48°).

[0175] The control center scans in real time, measures the actual bending angle as 48°, and retrieves parameters from the database.

[0176] Adaptive bending threshold: 30°

[0177] Excessive bending threshold: 45°

[0178] Ultimate bending threshold: 60°

[0179] 2. Control center decision-making (48° > 45° → incremental bending)

[0180] If the glass bending radius exceeds the excessive bending threshold, the composite layer (PVB+PET insulation layer) needs to be bent incrementally.

[0181] 3. Composite layer preparation and incremental bending

[0182] The molding tool heat-bends the composite layer (50°) (slightly greater than the glass's 48° to ensure proper fit and compensation).

[0183] The composite layer is pre-positioned based on the glass edge to avoid excessive stress in the central area.

[0184] 4. Tempering and bonding

[0185] The bent glass enters a cooling chamber for air-cooled tempering, forming a high-strength tempered glass substrate.

[0186] The bonding chamber presses the incrementally bent composite layer with tempered glass in a vacuum environment, eliminating air bubbles.

[0187] 5. Characteristics of the final product

[0188] Safety features: Passed the ECE R43 impact test, with no flying debris upon shattering.

[0189] Optical performance: The PVB layer compensates for the 2° curvature difference, with no visible distortion.

[0190] Thermal insulation performance: The PET layer effectively blocks 90% of infrared rays (compliant with GB / T 5137.3-2020).
