Description

Technical Field

[0001] The embodiments in this specification relate to glass forming technology, and particularly to a glass heating forming system, method, and glass assembly. Background Technology

[0002] Automotive laminated glass typically refers to a glass product made by bonding two panes of glass together with a single adhesive layer. The pane on the outside of the vehicle is usually called the outer pane, and the pane on the inside is called the inner pane. Automotive laminated glass is usually produced in a pressing furnace. The heating and transport steps are as follows: the two panes of glass are placed one after the other on ceramic rollers. The rotation of the ceramic rollers causes the two glass panes to move forward simultaneously within the furnace. Heating elements installed in the pressing furnace heat the two panes of glass until they reach the forming temperature. Once the temperature is reached, the two panes of glass move sequentially to the forming section, where they are pressed into shape using a mold. The heating elements installed in the furnace are usually fixed, therefore the distance between them and the glass is constant.

[0003] However, in most cases, car manufacturers have different requirements for the thickness and color of the outer and inner sheets. Therefore, the softening points and heat absorption capacities of the outer and inner sheets are also different. Under the existing heating mode, the outer and inner sheets soften to different degrees after heating, resulting in poor matching between the outer and inner sheets after pressing. Figure 1A The distance between the middle portion of the outer film 101 and the inner film 102 is too small. Figure 1B The excessive distance between the outer sheet 101 and the inner sheet 102 results in poor adhesion between them, affecting optical, stress, scratch, and pin-down performance. For example, for windshields, users might choose a combination of 2.1SG+1.8C or 2.1SG+1.6C sheets. However, due to significant differences in color and thickness, their heat absorption capacity also differs, leading to significant differences in the softening degree of the inner and outer sheets after heating. This results in defects such as optical distortion, scratch cracking, and bubbles in the outer sheet. Summary of the Invention

[0039] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0040] As mentioned earlier, the outer and inner sheets in automotive laminated glass have different softening points and heat absorption capacities. However, the existing heating methods do not differentiate between the outer and inner sheets during heating, resulting in different softening degrees after heating. This leads to poor matching between the outer and inner sheets after pressing and molding, which in turn affects optical, stress, scratch, and needle-drop performance issues.

[0041] To address the aforementioned problems, this specification provides an embodiment of a glass heating and forming system, which is described below in conjunction with... Figure 2 The glass heating and forming system described in the embodiments of this specification is described.

[0042] like Figure 2 As shown in the embodiments of this specification, a glass heating and forming system is proposed, which includes a heating device 201, a forming device 202, and a heating control system 203.

[0043] The heating device 201 is provided with heating zones 204, and each heating zone 204 is provided with a power-controllable heating module 205. There is at least one heating zone 204, and each heating zone 204 contains at least one power-controllable heating module 205. The power-controllable heating module 205 heats different types of glass (outer sheet 206 and inner sheet 207) transported in each heating zone 204 at different power levels.

[0044] In some embodiments of this specification, the different glass to be heated are the outer sheet 206 and inner sheet 207 constituting automotive laminated glass. The outer sheet 206 and inner sheet 207 can be transported in a heating device, and after passing through the heating zone, they are heated by a power-controllable heating module 205 and then enter the forming device 202.

[0045] The heating device 201 is provided with at least one heating zone 204, and the heating zone 204 is provided with at least one power-controllable heating module 205. Figure 2 The image shows two heating zones 204 and a power-controlled heating module 205 for each heating zone 204, but this is not intended to be limiting. The heating device can be any heating device with heating zones 204 and power-controlled heating modules 205, such as a heating furnace, and this application is not limited thereto.

[0046] When there are multiple heating zones 204 in the heating device 201, different heating zones are separated by partitions 209. A gap 210 is provided in the middle of the partition 209, and the glass to be heated can be transferred between adjacent heating zones 204 through the gap 210.

[0047] The power-controllable heating module 205 can change its power under the control of the heating control system 203 to differentiate and heat different types of glass to be heated in the heating zone 204.

[0048] The heating control system 203 is used to control the power of the power-controllable heating module 205 according to the type (e.g., outer sheet 206 or inner sheet 207) and position of the glass to be heated in the heating zone 204, and to control the forming equipment 202 to process and form the heated glass.

[0049] In some embodiments of this specification, the heating control system 203 may be a programmable logic controller (PLC), but this application is not limited thereto.

[0050] In some embodiments of this specification, the output power of the power-controllable heating module 205 is equal to the voltage multiplied by the current. The heating control system 203 can change the output power of the power-controllable heating module 205 by controlling its voltage or current, thereby changing the temperature of the heating zone 204 where the power-controllable heating module 205 is located, and heating different types of glass at different temperatures. Since the softening points and heat absorption capacities of the outer and inner sheets are different, in order to achieve the same softening degree after heating using the heating method of this application, the outer and inner sheets will match well after pressing and molding, and automotive laminated glass will not exhibit defects such as optical distortion, scratches, cracks, and lamination bubbles.

[0051] In some embodiments of this specification, such as Figure 2 As shown, the glass heating and forming system also includes a conveying device 208 for conveying the glass to be heated in the heating zone 204 of the heating device 201. The heating control system 203 can control the conveying device 208 to convey glass at a set speed via a servo motor connected to the conveying device 208.

[0052] The conveying device 208 can be a roller, but this application is not limited thereto.

[0053] In some embodiments of this specification, such as Figure 3 As shown, the glass heating and forming system also includes: a gripping device 301 and a loading controller 302. The loading controller 302 controls the gripping device 301 to grip different types of glass to be heated at intervals onto the transmission device 208, and sends the type of glass to be heated currently gripped to the heating control system 203.

[0054] Specifically, the loading controller 302 can control the gripping device 301 to periodically grip glass from different glass production lines and place it on the conveying device 208. Simultaneously, the loading controller 302 sends the type of glass currently gripped by the gripping device 301 to the heating control system 203. Taking automotive laminated glass as an example, the loading controller 302 can control the gripping device 301 to periodically grip outer and inner sheets from the outer sheet production line and place them on the conveying device 208. If the currently gripped glass is an outer sheet, the loading controller 302 sends the type of outer sheet glass currently gripped by the gripping device 301 to the heating control system 203.

[0055] In some embodiments of this specification, such as Figure 3 As shown, the glass heating and forming system also includes a sensing device 303, which is located at the entrance of the heating device 201 and connected to the heating control system 203. The glass to be heated, gripped by the gripping device 301, is placed on the conveying device 208 at the entrance of the heating device 201. The sensing device 303 can sense the position of the gripped glass to be heated, and this position is transmitted to the heating control system 203 as the initial position of the glass to be heated.

[0056] In specific implementation, the gripping device 301 can be a robotic arm, and the sensing device 303 can be a light sensing device; this application is not limited to these.

[0057] Figure 4 This is a schematic diagram of a glass heating and forming system according to another embodiment of this specification. The glass to be heated is the outer and inner sheets of automotive laminated glass, as shown below. Figure 4 As shown, the outer sheet is located on the outer sheet production line 401, and the inner sheet is located on the inner sheet production line 402. Under the control of the upper sheet controller 302, the robot arm 301 can grasp the outer sheet 403 on the outer sheet production line 401 or the inner sheet 404 on the inner sheet production line 402, and place the grasped outer sheet 403 and inner sheet 404 on the conveying device 208 at the furnace inlet. The robot arm 301 can grasp the outer sheet 403 and inner sheet 404 alternately, allowing them to enter the furnace alternately. The photosensitive device 303 located at the furnace inlet can sense the initial positions of the outer sheet 403 and inner sheet 404 placed on the conveying device at the furnace inlet and send the sensed initial positions to the heating control system 203.

[0058] After receiving the initial position of the glass to be heated, the heating control system 203 can record the transmission time of the glass on the transmission device 208. Based on the initial position of the glass to be heated, the transmission time of the glass to be heated, and the transmission speed of the glass to be heated (i.e., the transmission speed of the transmission device 208), the heating control system 203 can calculate the position of the glass to be heated in the heating device 201 at different times.

[0059] In some embodiments of this specification, the method for calculating the position of the glass to be heated in the heating device 201 at different times is as follows: the distance of glass transmission can be obtained based on the transmission time and transmission speed; based on the glass transmission distance and initial position, and based on the position of each heating zone (the size of each heating zone along the transmission direction and the distance between heating zones are known, and each heating zone in the heating device can be marked with a scale in the transmission direction), the position of the glass to be heated in the heating device 201 at different times can be determined.

[0060] Depending on the type of glass to be heated and its real-time position, the heating control system 203 can adjust the power of the corresponding power-controllable heating module, that is, adjust the temperature of the heating zone where the power-controllable heating module is located, and use different heating temperatures to heat different types of glass.

[0061] The output power of the power-controllable heating module 205 is equal to the voltage multiplied by the current. The output power can be adjusted by adjusting either the current or the voltage of the power-controllable heating module 205, thereby controlling the temperature of the heating zone where the power-controllable heating module is located.

[0062] Figure 5 This is a schematic diagram of the structure of a glass heating and forming system according to one embodiment of this specification. Figure 5 In the heating device 201, there are 10 heating zones (zone 1 to zone 10). The glass to be heated can be transferred from zone 1 to zone 10 via roller 208, and then transferred to the forming device 202 via roller 208 for glass forming operation.

[0063] In the multiple heating zones of the heating device 201, only some heating zones may be temperature-adjustable, meaning only the power of the heating modules in some heating zones may be adjustable. In specific implementations, the power of the heating modules in zones 1 to 5 may be fixed, while the power of the heating modules in zones 6 to 10 may be adjustable. That is, zones 1 to 5 may use a traditional heating mode, while zones 6 to 10 may use a heating mode where the heating modules can move in accordance with the glass to be heated. This application is not limited to this.

[0064] This application allows different types of glass to reach the same temperature by making the temperature of some or all of the heating zones adjustable, thus ensuring that different types of glass soften to the same degree and improving the compatibility between different types of glass after pressing and molding.

[0065] In some embodiments of this specification, such as Figure 5As shown, the forming equipment 202 includes: a punch 501, a die 502, a first lifting mechanism, and a second lifting mechanism (the lifting mechanism is not shown in the figure). In specific implementation, the forming equipment 202 is set in the forming area 503. The roller 208 conveys the heated glass to the die 502 of the forming equipment 202. The first lifting mechanism drives the punch 501 to descend, and the second lifting mechanism drives the die 502 to rise, so that the punch 501 and the die 502 cooperate to compress the heated glass (outer sheet 403 and inner sheet 404) to achieve glass forming.

[0066] Since different types of glass are heated to the same temperature, they can achieve a good match after being formed by the forming equipment 202.

[0067] In some embodiments of this specification, such as Figure 5 As shown, the glass heating and forming system of this application also includes an annealing fan 504, which is disposed in the annealing zone 505. The annealing fan 504 is used to perform annealing operations on different types of glass after forming.

[0068] The glass thermoforming system of this application also includes: a carrier 507 and an annealing ring 506 disposed on the carrier 507. The annealing ring 506 is used to support the formed glass, and the carrier 507 is used to transport the formed glass to the annealing zone. Since different types of glass are heated to the same temperature, after being formed by the forming equipment 202 and annealed by the annealing fan 504, different types of glass can achieve good matching.

[0069] In practice, the carrier 507 can move horizontally. After the forming equipment 202 completes the forming operation on the heated glass, the punch 501 can hold the formed glass. When the carrier 507 moves below the punch 501, it can control the glass held on the punch 501 to fall onto the annealing ring 506. The carrier 507 then transfers the glass to the annealing zone 505 for annealing.

[0070] In some embodiments of this specification, such as Figure 5 As shown, the glass heating and forming system of this application is also provided with a cooling zone 508, and the annealed glass can be transferred from the annealing zone 505 to the cooling zone 508 by a carrier 507.

[0071] Cooling is achieved using the cooling equipment in cooling zone 508. The cooling equipment could be, for example, an axial flow fan. Specifically, during cooling, two support blocks 509 can be installed on the carrier to support the glass to be cooled.

[0072] In practice, the annealed glass can be adsorbed by the vacuum generator (not shown in the figure) under the annealing fan 504. When the support block 509 on the carrier 507 moves to a position below the vacuum generator, the glass falls onto the support block 509 for cooling. The support block 509 can slide horizontally. After cooling, it can be conveyed through the roller conveyor 510 for automotive glass processing.

[0073] Different types of glass, once cooled, have good compatibility. Combining different types of glass (such as the aforementioned automotive laminated glass) will not affect the optical, stress, scratch, and pin-drop properties of the resulting product, and will not cause defects such as optical screen distortion, scratch cracking, or lamination bubbles.

[0074] In some embodiments of this specification, such as Figure 5 As shown, the heating module is along the transmission direction of the glass to be heated ( Figure 5 The width 'a' of the glass (in the direction of glass flow) is smaller than the width 'b' of the glass to be heated. This ensures that a single heating module will not span two pieces of glass for heating, making it easy to control the temperature of the glass to be heated.

[0075] Preferably, the width b is about 0-400 mm wider than the width a, but this application is not limited thereto.

[0076] It should be noted that, in order to prevent the glass from spanning heating modules in different heating zones, the distance between adjacent heating modules in different heating zones can be greater than the width of the glass.

[0077] In some embodiments of this specification, such as Figure 5 As shown, the width c of the heating zone along the transport direction of the glass to be heated is greater than the width b of the glass. Since the temperature of a heating zone is the same, a width c greater than a width b allows the heating zone to completely cover a piece of glass, ensuring stable glass temperature. Another heating zone may have two or more heating modules; the width of both heating modules should be greater than the width b of the glass to be heated.

[0078] Preferably, the width c is about 500-1000 mm wider than the width a, but this application is not limited thereto.

[0079] In some embodiments of this specification, each heating zone is equipped with a temperature sensor, which is connected to the heating control system 203. The temperature sensor is used to measure the real-time temperature of the heating zone. The heating control system can adjust the power of the heating module according to the real-time temperature to make the heating zone reach a preset temperature, so as to ensure that the same piece of glass or the same type of glass is heated in a heating zone with a stable temperature.

[0080] In some embodiments of this specification, the outlet of the heating device 201 is equipped with a thermal imager (not shown in the figure). The thermal imager is used to detect the temperature of the heated glass. The heating control system adjusts the power of the power-controllable heating module according to the temperature difference of different heated glasses to correct the temperature difference and maximize the uniformity of the heated glass temperature, thereby ensuring the yield of the finished assembled glass.

[0081] Referring to the comparison table below (Table 1), the effect of the automotive glass processed by this application is explained by comparing it with existing heating methods:

[0082] Table 1

[0083]

[0084] Table 1 explains the process from the perspectives of furnace exit temperature, inner and outer sheet matching, optics (refractive power), and optical finish. It should be noted that the colors of the outer and inner sheets to be heated in automotive glass may differ (or be the same). Generally, the smaller the color difference, the smaller the required temperature difference between the outer and inner sheets. Table 1 is for illustrative purposes only; the thickness of the outer sheet material is approximately 2.1 mm, and the thickness of the inner sheet material is approximately 1.8 mm. There is a certain color difference between the outer and inner sheets to be heated. In Table 1, regarding the furnace exit temperature, the temperature difference between the outer and inner sheets obtained using the glass forming system of this application is 633-627 = 6℃, which is a significant improvement compared to the 20℃ temperature difference in existing heating modes. Regarding the matching of inner and outer sheets, the gap between the outer and inner sheets obtained using the glass forming system of this application is 0.3 mm to 0.6 mm, which is a significant improvement compared to the 1.5 to 2.0 mm gap in existing heating modes. Figure 6 This diagram illustrates a laminated automotive glass (used for a vehicle's windshield, i.e., a glass assembly) manufactured using the glass thermoforming system described in the embodiments of this specification. Figure 6 As shown, for optics (refractive power), the refractive power range of the central area (area A) and peripheral area (area B) of the automotive laminated glass obtained using the glass forming system of this application is 65 mdpt to 85 mdpt and 90 mdpt to 125 mdpt, respectively, which is significantly smaller than the refractive power range of the central and peripheral areas of the outer and inner sheets under the existing heating mode. The optical yield of the automotive laminated glass obtained using the glass forming system of this application is 99%, which is significantly higher than the optical yield of automotive laminated glass under the existing heating mode.

[0085] Based on the same inventive concept, this specification also proposes a glass heating and forming method, which is described below in conjunction with... Figure 7 The glass heating and forming method in the embodiments of this specification is described.

[0086] Based on the same inventive concept, this application also provides a glass thermoforming method, which can be used to implement the glass thermoforming system described in the above embodiments, as described in the following embodiments. Since the principle of the glass thermoforming method in solving the problem is similar to that of the glass thermoforming system, the implementation of the glass thermoforming method can refer to the implementation of the glass thermoforming system, and repeated details will not be elaborated further. As used below, the terms "unit" or "module" can refer to a combination of software and / or hardware that implements a predetermined function. Although the system described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0087] like Figure 7 As shown in the embodiments of this specification, a glass heating and forming method is proposed. The main body executing the glass heating and forming method can be a heating control system. The glass heating and forming method includes:

[0088] S701: Obtain the temperature of the heating zone, the initial position of the glass to be heated, the transmission time of the glass to be heated, and the transmission speed of the glass to be heated;

[0089] The temperature of the heating zone can be measured by a temperature sensor installed in the heating zone, which is connected to the heating control system 203.

[0090] The initial position is the initial position of the glass to be heated on the transfer device at the entrance of the heating furnace. The photosensitive device 303 located at the entrance of the heating furnace can sense the initial position of the glass placed on the transfer device at the entrance of the heating furnace and send the sensed initial position to the heating control system 203.

[0091] S702: Determine the real-time position of the glass to be heated in the heating device based on the initial position, the transmission time, and the transmission speed;

[0092] S703: Adjust the power of the corresponding power-controllable heating module according to the temperature of the heating zone, the type of glass to be heated, and the real-time position, so that the corresponding heating zone reaches the preset temperature, so as to heat different glass to be heated in the heating zone at different power levels.

[0093] In some embodiments of this specification, such as Figure 8 As shown, the glass heating and forming method further includes:

[0094] S801: Obtain the temperature of different glasses after heating and calculate the temperature difference;

[0095] The temperature of the heated glass can be detected by a thermal imager installed at the outlet of the heating device 201.

[0096] S802: Adjust the power of the power-controllable heating module according to the temperature difference to correct the temperature difference.

[0097] By correcting the temperature difference, the compatibility between glass panes can be improved.

[0098] In some embodiments of this specification, the glass heating and forming method further includes: acquiring the real-time temperature of the heating zone, and adjusting the power of the heating module according to the real-time temperature so that the heating zone reaches a preset temperature.

[0099] Specifically, the real-time temperature of the heating zone can be measured by a temperature sensor installed in the heating zone. By controlling the power based on the real-time temperature, the heating temperature of the glass can be made more accurate.

[0100] Based on the same inventive concept, this application also provides a glass assembly, including an adhesive material and a first curved glass plate and a second curved glass plate made by the above-described glass thermoforming method, wherein the first curved glass plate and the second curved glass plate are different types of glass plates; the first curved glass plate and the second curved glass plate are bonded together by the adhesive material.

[0101] In one embodiment, the gap between the first curved glass plate and the second curved glass plate is 0.3 mm to 0.6 mm, but this application is not limited thereto.

[0102] In one embodiment, the refractive power range of the glass assembly in the central region is 65 mdpt to 85 mdpt, and the refractive power range of the glass assembly in the peripheral region is 90 mdpt to 125 mdpt, but this application is not limited thereto.

[0103] The instruction manual is required because different types of glass plates (i.e., different types of glass to be heated) generally refer to glass plates with different heat absorption capacities. Different types of glass plates include at least one of the following: different glass plate sizes, different glass plate thicknesses, different types of glass plate coatings, and whether the glass plate contains printed ink.

[0104] Based on the same inventive concept, this application also provides a vehicle, including a body and the above-mentioned glass assembly, wherein the glass assembly is disposed on the body.
