Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and in particular, to a method and apparatus for bending and heating glass sheets. Background Technology

[0002] The bending and forming of glass mainly involves heating the glass to its softening temperature, pressing it into shape using a mold, and then rapidly cooling and solidifying it. Current technologies primarily employ continuous bending furnaces or twin-plate pressing furnaces for the production of curved glass. However, furnace temperatures fluctuate due to environmental and voltage factors, causing fluctuations in the heat absorbed by the glass. This affects the degree of softening, ultimately resulting in variations in the final glass shape and a low yield rate. This is particularly problematic for windshields of vehicles equipped with ADAS (Advanced Driving Assistance System), HUD (Head-Up Display), and coated reflective glass, where high spherical precision is required.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Implementation Method 1

[0037] like Figure 1 , Figure 5 and Figure 6 As shown, the present invention provides a method for bending and heating a glass plate, comprising the following steps: dividing the glass plate 1 into at least one first forming control area 11 and at least one second forming control area 12; wherein, the precision requirement of the first forming control area 11 is higher than the precision requirement of the second forming control area 12; dividing the heating cavity of the furnace body into at least one partitioned heating forming area 51 ( Figure 10 and Figure 11 (as shown in the diagram), wherein the partitioned heating forming area 51 has two heating areas located above and below the glass plate 1; the two heating areas are evenly divided into multiple heating partitions 3; wherein each heating partition 3 has at least one heating structure 21, combined with Figures 1 to 3As shown, the multiple heating zones 3 include multiple first heating zones S1; based on the distribution length of the first forming control zone 11 in the length direction X of the glass plate 1 (i.e., the length dimension of the first forming control zone 11) and the distribution width of the first forming control zone 11 in the width direction Y of the glass plate 1 (i.e., the width dimension of the first forming control zone 11), the areas corresponding to the first forming control zone 11 of the two heating zones are evenly divided to form multiple first heating zones S1; the heating structure 21 of each heating zone 3 is controlled to heat and bend the glass plate 1 into shape; wherein, during the heating process of each heating structure 21, the real-time temperature of each heating zone 3 is monitored, and the heating parameters of the heating structure 21 of each heating zone 3 are adjusted according to the temperature difference between the real-time temperature of each heating zone 3 and the target temperature.

[0038] The glass plate bending and heating forming method of the present invention divides the glass plate 1 into multiple forming control zones with different precision requirements, and divides the two heating zones located above and below the glass plate 1 into multiple heating zones 3. The first forming control zone 11 of the glass plate 1 is heated in sections by multiple first heating zones S1, so that the different forming control zones of the glass plate 1 soften in sections under different temperature differences, and then bend and form under the action of gravity, thereby realizing the section control forming of the glass plate 1, which is beneficial to improving the processing precision of the first forming control zone 11. In addition, during the heating process, by monitoring the real-time temperature of each heating zone 3, and accurately adjusting the heating parameters of the heating structure 21 of each first heating zone S1 according to the temperature difference between the real-time temperature of each heating zone 3 and the target temperature, the impact of temperature fluctuation on the glass plate 1 is reduced, which is beneficial to further improving the processing precision of the first forming control zone 11.

[0039] Specifically, multiple heating zones 3 are arranged in multiple rows and columns along the length direction X and width direction Y of the glass plate 1, roughly forming a grid. The target temperatures of each heating zone 3 can be different, or partially different and partially the same, but the target temperature of one heating zone 3 is different from that of at least one adjacent heating zone 3, thus forming a temperature difference, causing the glass plate 1 to bend and shape under the action of the temperature difference. In addition, after determining each heating zone 3, the partitioned heating and shaping of the glass plate 1 can be simulated using simulation forming software, thereby analyzing and determining the simulated temperature field distribution law of the glass plate 1 in the partitioned heating and shaping zone 51. Then, based on the simulated temperature field distribution law, the target temperature of each heating zone 3 is optimized and adjusted, thereby determining the target temperature of each heating zone 3.

[0040] The glass sheet bending and heating forming method of the present invention is particularly suitable for the bending and heating forming of vehicle windshields. Specifically, it is applicable to the bending and heating forming of windshields with a length range of 700mm to 1700mm and a width range of 600mm to 1250mm, and is particularly suitable for the bending and heating forming of windshields with a length range of 1400mm to 1600mm and a width range of 800mm to 12000mm.

[0041] Combination Figure 1 As shown, the number, size, position, and accuracy requirements of the first molding control area 11 can be set as needed. In some embodiments of the present invention, there are multiple first molding control areas 11, and the accuracy requirements of the multiple first molding control areas 11 can be the same or different, but all are higher than the accuracy requirements of each second molding control area 12. The sizes of the multiple first molding control areas 11 can be the same or different. In other embodiments of the present invention, there is only one first molding control area 11. The accuracy requirements of the first molding control area 11 of the glass plate 1 may include, but are not limited to, at least one of the following: spherical tolerance range, fluctuation value range, and profile value range.

[0042] Combination Figure 1 As shown, in some embodiments of the present invention, at least one first forming control area 11 is an information transmission area 111 of the glass plate 1. Specifically, vehicle-mounted sensors such as radar, cameras, and lidar collect information through the information transmission area 111 of the glass plate 1, including but not limited to driver assistance information, and then transmit the driver assistance information to the Advanced Driving Assistance System (ADAS).

[0043] Combination Figure 1 As shown, in some embodiments of the present invention, at least one first forming control area 11 is a head-up display area 112 of the glass plate 1. Specifically, the head-up display area 112 (HUD) is used to display driving information such as vehicle speed, navigation, and steering.

[0044] The accuracy requirements of the information transmission area 111 and the head-up display area 112 of the glass plate 1 can be the same or different. For example, in some specific embodiments of the invention, the accuracy requirements of the information transmission area 111 and the head-up display area 112 are the same, which can include a spherical tolerance of no more than ±1.5mm or a spherical tolerance of no more than ±1mm. It can also include a fluctuation value between two points 100mm apart that does not exceed 1.0mm or a fluctuation value between two points 50mm apart that does not exceed 1.0mm.

[0045] Combination Figure 1 , Figure 5 , Figure 8 As shown, the number, size, and position of the second molding control area 12 can also be set as needed. In some embodiments of the present invention, there is one second molding control area 12, that is, the area on the glass plate 1 located outside the first molding control area 11 constitutes a second molding control area 12. In other embodiments of the present invention, there are multiple second molding control areas 12, and the precision requirements of the multiple second molding control areas 12 can be the same or different, but all are lower than the precision requirements of each first molding control area 11.

[0046] Combination Figures 1 to 3 and Figures 5 to 8 As shown, in an embodiment of the present invention, the regions of the two heating zones corresponding to the first forming control zone 11 are evenly divided to form a plurality of first heating zones S1, including: according to the distribution length and distribution width of the first forming control zone 11, the regions above and below the first forming control zone 11 are divided along the width direction Y and / or along the length direction X of the glass plate 1 to form a plurality of first heating zones S1.

[0047] Specifically, the multiple heating structures 21 in the two heating zones are arranged along the length direction X and the width direction Y of the glass plate 1, that is, the multiple heating structures 21 are arranged in multiple rows and columns. The number and area of ​​the first heating zones S1 corresponding to the first forming control zone 11 are related to the size of the first forming control zone 11 (i.e., its distribution length and distribution width), the size of the heating structures 21 in the heating zone, and the arrangement spacing between the multiple heating structures 21. It should meet the following condition: the distribution length of the multiple first heating zones S1 (e.g., the distribution length and distribution width of the first forming control zone 11) is related to the size of the heating structures 21 in the heating zone and the arrangement spacing between the multiple heating structures 21. Figure 2 The length dimension L1 and Figure 3 The length dimension L2 in the middle should be greater than or equal to the distribution length of the first molding control area 11, and the distribution width of the multiple first heating zones S1 (e.g., Figure 2 Width dimension W1 and Figure 3 The width dimension W2 in the first molding control area 11 should be greater than or equal to the distribution width of the first molding control area 11, so that the sum of the areas of the multiple first heating zones S1 is greater than or equal to the area of ​​their corresponding first molding control area 11; the number of heating structures 21 arranged along the length direction X in each first heating zone S1 is less than or equal to four, and the number of heating structures 21 arranged along the width direction Y in each first heating zone S1 is less than or equal to two.

[0048] like Figure 1 , Figure 5 and Figure 6As shown, in an embodiment of the present invention, both heating zones are divided along the length direction X of the glass plate 1 to form multiple longitudinal heating zones 4; the multiple longitudinal heating zones 4 include at least one first longitudinal heating zone 41. The multiple heating zones also include multiple second heating zones S2; dividing the two heating zones into multiple heating zones 3 further includes: dividing the areas of the two heating zones corresponding to the distribution length of the multiple first heating zones S1 corresponding to the first forming control zone 11 along the length direction X of the glass plate 1 to form at least one first longitudinal heating zone 41; wherein, the first longitudinal heating zone 41 includes multiple second heating zones S2 distributed along the width direction Y of the glass plate 1 and at least one first heating zone S1, and the area of ​​the second heating zone S2 is greater than or equal to the area of ​​the first heating zone S1.

[0049] In addition, combined Figures 1 to 3 as well as Figures 5 to 8 As shown, when there are multiple first forming control areas 11 and multiple first longitudinal heating areas 41 are formed accordingly, the closer the first longitudinal heating area 41 is to the center of the glass plate 1, the more second heating partitions S2 are distributed in the first longitudinal heating area 41 and the smaller the area of ​​the second heating partitions S2.

[0050] Combination Figure 1 and Figure 4 as well as Figure 5 , Figure 6 , Figure 9 As shown, in an embodiment of the present invention, the plurality of longitudinal heating zones 4 further include at least one second longitudinal heating zone 42. The plurality of heating partitions 3 further include a plurality of third heating partitions S3; dividing the two heating zones into a plurality of heating partitions 3 further includes: dividing the areas of the two heating zones outside the first longitudinal heating zone 41 along the length direction X of the glass plate 1 to form a plurality of second longitudinal heating zones 42; dividing each second longitudinal heating zone 42 along the width direction Y of the glass plate 1 to form a plurality of third heating partitions S3; wherein the area of ​​the third heating partition S3 is larger than the area of ​​the second heating partition S2. Specifically, the plurality of first longitudinal heating zones 41 are arranged along the length direction X of the glass plate 1 between the two second longitudinal heating zones 42.

[0051] like Figure 10 and Figure 11 As shown, in an embodiment of the present invention, the heating cavity of the furnace body is divided into at least one partitioned heating and forming zone 51, which includes the following steps: dividing the heating cavity of the furnace body into multiple heating and forming zones 5 from front to back along the conveying direction F of the glass plate 1; selecting at least one heating and forming zone 5 as the partitioned heating and forming zone 51.

[0052] Specifically, the conveying direction F of the glass plate 1 is the same as the length direction of the furnace body and also the same as the width direction Y of the glass plate 1, while the width direction of the furnace body is the same as the length direction X of the glass plate 1. First, the heating chamber of the furnace body is divided from front to back along the conveying direction F of the glass plate 1 to form a preheating zone, a pre-arching heating zone, and an arching heating forming zone; then, the preheating zone, the pre-arching heating zone, and the arching heating forming zone are all divided from front to back along the conveying direction F of the glass plate 1 to form multiple heating forming zones 5, respectively denoted as Zone 1, Zone 2, ..., Zone N-1, Zone N. The number of heating forming zones 5 is not specifically limited; preferably, two to six heating forming zones 5 are selected from the last six heating forming zones 5 as partitioned heating forming zones 51 to perform partitioned heating of the glass plate 1, thereby precisely controlling the shape of the glass plate 1 before final forming, improving processing accuracy, and ensuring that the first forming control zone 11 meets high-precision requirements after forming. For example... Figure 10 As shown, the last four heating and forming zones 5 are all used as partitioned heating and forming zones 51 to heat the glass plate 1 in partitioned areas; for example... Figure 11 As shown, the multiple heating and forming zones 5 arranged at the end constitute the arched heating and forming zone. Among the multiple heating and forming zones 5 in the arched heating and forming zone, one to three are selected as partitioned heating and forming zones 51 to perform partitioned heating on the glass plate 1.

[0053] Combination Figure 1 and Figure 11 As shown, in an embodiment of the present invention, the glass plate bending and heating forming method further includes the following steps: after the glass plate 1 is output from the preceding heating forming zone 5 of the partitioned heating forming zone 51 and before it is conveyed to the partitioned heating forming zone 51, the initial temperatures of the first forming control zone 11 and the second forming control zone 12 of the glass plate 1 are monitored; after the glass plate 1 is output from the preceding heating forming zone 5 of the partitioned heating forming zone 51 and before it is conveyed to the partitioned heating forming zone 51, the heating parameters of the heating structure 21 of each heating zone 3 are adjusted according to the initial temperatures of the first forming control zone 11 and the second forming control zone 12 of the glass plate 1. Combined with... Figure 1 As shown, the heating parameters of the heating structure 21 of each heating zone 3 are adjusted according to the temperature difference between the real-time temperature and the target temperature of each heating zone 3. This includes: when the temperature difference between the actual temperature and the target temperature of the heating zone 3 exceeds 1.5℃, adjusting the heating parameters of the heating structure 21 of that heating zone 3 until the temperature difference is below 0.1℃. The heating structure 21 can be, but is not limited to, a heating wire assembly, and the heating parameters can be, but are not limited to, heating power. Furthermore, when a heating zone 3 has multiple heating structures 21, the heating parameters of the multiple heating structures 21 can be the same or different, as long as the temperature difference between the real-time temperature and the target temperature of the heating zone 3 meets the requirements.

[0054] Specifically, heating parameters are adjusted using PID intelligent control to keep the temperature difference below 0.1℃. Furthermore, the real-time temperature of heating zone 3 can be the surface temperature of glass plate 1 at one or more fixed locations within the heating zone 3, or the temperature at one or more spatial locations within the heating zone 3. Moreover, to further reduce temperature fluctuations, it is preferable to monitor the real-time temperature of each heating zone 3 at a preset frequency. In one specific embodiment, when the temperature difference between the real-time temperature and the target temperature of a heating zone falls within the range of -10℃ to 4℃, temperature difference control is performed using PID intelligent heating to ensure that the temperature difference between the real-time temperature and the target temperature of each heating zone does not exceed ±0.1℃.

[0055] Combination Figure 1 As shown, to facilitate subsequent optimization of processing parameters and to facilitate the subsequent processing of other glass plates 1, in this embodiment of the invention, the geometric parameters of the glass plate 1 and the geometric parameters of each first forming control zone 11 are recorded in the structural parameter group of the glass plate 1; the real-time temperature and target temperature of each heating zone 3 are recorded in the temperature parameter group of the glass plate 1. The structural parameter group and temperature parameter group of the processed glass plate 1 provide reference value for setting the target temperature of each heating zone 3 when processing a new glass plate 1. For example, the target temperature of each heating zone 3 of the newly processed glass plate 1 can be set by referring to the temperature parameter group corresponding to a processed glass plate 1 with similar structural parameters, or it can be directly called first and then adjusted. Among them, the geometric parameters of the glass plate 1 include, but are not limited to, the specifications, spherical surface, arch height, column depth, and center height of the glass plate 1 before and after processing. In addition, the structural parameter group may also include parameters such as the combination of inner and outer glass sheets.

[0056] Combination Figure 1 As shown, after the glass plate 1 is bent and heated into shape, the bending and heating method of the glass plate 1 further includes the following steps: Multiple spherical measurement points are set in both the first forming control area 11 and the second forming control area 12 of the glass plate 1; a glass spherical test is performed on the glass plate 1 to measure the spherical value at each spherical measurement point; based on the spherical values ​​of the multiple spherical measurement points located in the first forming control area 11 and the preset spherical standard value, the profile value of the multiple spherical measurement points in the first forming control area 11 is analyzed and obtained; the spherical values ​​at each spherical measurement point and the profile values ​​of the multiple spherical measurement points located in the first forming control area 11 are recorded in the structural parameter group of the glass plate 1. The profile value is the difference between the spherical value and the spherical standard value.

[0057] In addition, combined Figure 1As shown, multiple spherical measurement points located in the first forming control area 11 are arranged along the length direction X and the width direction Y of the glass plate 1 and are set at preset intervals. After the glass plate 1 is bent and heated to form, the glass plate 1 bending and heating forming method further includes the following steps: based on the spherical values ​​of the multiple spherical measurement points arranged along the length direction X of the glass plate 1 in the first forming control area 11, multiple lateral fluctuation values ​​of the first forming control area 11 are analyzed; based on the spherical values ​​of the multiple spherical measurement points arranged along the width direction Y of the glass plate 1 in the first forming control area 11, multiple longitudinal fluctuation values ​​of the first forming control area 11 are analyzed; the multiple lateral fluctuation values ​​and the multiple longitudinal fluctuation values ​​are recorded in the structural parameter group of the glass plate 1. Among them, the lateral fluctuation value is the difference between the spherical values ​​of two spherical measurement points spaced at a preset distance in the length direction X; the longitudinal fluctuation value is the difference between the spherical values ​​of two spherical measurement points spaced at a preset distance in the width direction Y.

[0060] Combination Figure 1 , Figure 5 as well as Figure 10 and Figure 11 As shown, the present invention also provides a glass plate bending and heating forming device, including a furnace body and at least one partitioned heating forming device. The furnace body is provided with at least one partitioned heating forming area 51. The partitioned heating forming device includes: two heating mechanisms 2, installed in the partitioned heating forming area 51 of the furnace body and respectively located above and below the glass plate 1. Each of the two heating mechanisms 2 includes multiple heating structures 21; a temperature monitoring mechanism 6, including a real-time temperature monitoring structure 61; and a heating control mechanism, which is electrically connected to each heating structure 21 and the real-time temperature monitoring structure 61 respectively. The heating control mechanism is used to control the heating parameters of the multiple heating structures 21 of the two heating mechanisms 2 respectively, so as to divide the heating area of ​​the two heating mechanisms 2 into multiple heating partitions 3. The real-time temperature monitoring structure 61 is used to monitor the real-time temperature of the multiple heating partitions 3.

[0061] The glass plate bending and heating forming equipment of the present invention can process glass plate 1 using the glass plate bending and heating forming method in Embodiment 1. Specifically, before processing different glass plates 1, the glass plate bending and heating forming equipment of the present invention can first divide the glass plate 1 into sections using the glass plate bending and heating forming method in Embodiment 1, and then divide the sections by controlling the heating parameters of each heating structure of the two heating mechanisms 2. Multiple commonly used heating sections can also be formed, and then it can be determined whether the heating section is suitable for the glass plate to be processed during the glass plate processing.

[0062] Specifically, the real-time temperature monitoring structure 61 is installed inside the furnace and above the zoned heating and forming zone 51. It can monitor the real-time temperature of multiple heating zones 3 at a preset acquisition frequency and upload the data to the heating control mechanism. The real-time temperature monitoring structure 61 can be a thermal imager, multiple infrared temperature sensors corresponding to the multiple heating zones 3, or other available temperature detection devices in the prior art.

[0063] like Figure 1 , Figure 5 , Figure 6 As shown, in the embodiment of the present invention, multiple heating structures 21 are arranged along the length direction X and the width direction Y of the glass plate 1, and multiple heating zones 3 are arranged along the length direction X and the width direction Y of the glass plate 1. Each heating structure 21 is located inside the corresponding heating zone 3. That is, when the temperature of a heating zone 3 needs to be adjusted, the heating control mechanism only adjusts the heating structure 21 located in that heating zone 3. And since the heating structure 21 is located inside the heating zone 3, the impact of adjusting the heating parameters of the heating structure 21 on other surrounding heating zones 3 can be reduced.

[0064] Furthermore, the heating control mechanism can transmit the heating parameters of each heating zone 3 and each heating structure 21 to a display device, wherein the magnitude of the heating parameters of each heating structure 21 can be displayed using bar-shaped patterns of different lengths (such as...). Figure 5 and Figure 6 (As shown) for easy viewing. In this embodiment, the heating parameters include the heating power of the heating structure 21, and the adjustment range of the heating power of each heating structure 21 is 0 to 100%.

[0065] like Figure 10 and Figure 11 As shown, in an embodiment of the present invention, multiple heating and forming zones 5 are arranged from front to back along the conveying direction F of the glass plate 1 inside the furnace body, and at least one heating and forming zone 5 is a partitioned heating and forming zone 51. In one embodiment as shown in 10, the last four heating and forming zones 5 are all partitioned heating and forming zones 51, and four real-time temperature monitoring structures 61 are correspondingly installed above the four partitioned heating and forming zones 51. Figure 11 In another embodiment shown, the second-to-last and third-to-last heating and forming zones 5 are arranged as partitioned heating and forming zones 51, and two real-time temperature monitoring structures 61 are installed above the two partitioned heating and forming zones 51 respectively.

[0066] like Figure 11 As shown, in an embodiment of the present invention, the temperature monitoring mechanism 6 further includes an initial temperature acquisition structure 62. The initial temperature acquisition structure 62 is installed inside the furnace and located between the partitioned heating and forming zone 51 and the previous heating and forming zone 5. The initial temperature acquisition structure 62 is electrically connected to the heating control mechanism. The initial temperature acquisition structure 62 is used to acquire the initial temperature of each forming zone of the glass plate 1 and upload it to the heating control mechanism. The initial temperature acquisition structure 62 can be a thermal imager.

[0067] like Figure 1 As shown, in the embodiment of the present invention, a plurality of heating structures 21 are arranged along the length direction X and the width direction Y of the glass plate 1, and a plurality of heating partitions 3 are arranged along the length direction X and the width direction Y of the glass plate 1, and each heating structure 21 is entirely located inside the corresponding heating partition 3.

[0068] To facilitate understanding and implementation of the glass plate bending and heating forming method and equipment of the present invention, a specific embodiment is provided as follows: Combination Figures 1 to 4 As shown, here is a specific embodiment one: The glass plate 1 has a length of 1400mm to 1600mm and a width of 800mm to 1200mm. The two head-up display areas 112 and the information transmission area 111 of the glass plate 1 form three first forming control areas 11, while the other areas of the glass plate 1 form second forming control areas 12.

[0069] The heating zones of both heating mechanisms 2 are divided into 21 heating zones 3: It includes two first heating zones S1 (denoted as first heating zone S11 and first heating zone S12) corresponding to one head-up display area 112, two first heating zones S1 (denoted as first heating zone S13 and first heating zone S14) corresponding to another head-up display area 112, and one first heating zone S1 (denoted as first heating zone S15) corresponding to the information transmission area 111, that is, a total of five first heating zones 3; It also includes three second heating zones S2 (denoted as second heating zone S21, second heating zone S22, and second heating zone S23) that cooperate with the first heating zone S11 and the first heating zone S12 to form a first longitudinal heating zone 41; three second heating zones S2 (denoted as second heating zone S24, second heating zone S25, and second heating zone S26) that cooperate with the first heating zone S13 and the first heating zone S14 to form another first longitudinal heating zone 41; and four second heating zones S2 (denoted as second heating zone S27, second heating zone S28, second heating zone S29, second heating zone S20, second heating zone S21, second heating zone S21, second heating zone S21, second heating zone S21, second heating zone S21, second heating zone S22, and second heating zone S22) that cooperate with the first heating zone S15 to form yet another first longitudinal heating zone 41. There are ten second heating zones 3 (S28, S29, and S210), which together with five first heating zones 3 form three first longitudinal heating zones 41. Each first longitudinal heating zone 41 corresponds to a first forming control zone 11. The first longitudinal heating zone 41 corresponding to the information transmission zone 111 is closest to the center of the glass plate 1. Therefore, the distribution length (i.e., length dimension L1) of each second heating zone S2 in the first longitudinal heating zone 41 is smaller than the distribution length (i.e., length dimension L2) of each second heating zone S2 in the other two first longitudinal heating zones 41, and the number of them is greater. It also includes three third heating zones S3 (denoted as third heating zone S31, third heating zone S32, and third heating zone S33) that cooperate to form a second longitudinal heating zone 42, and three third heating zones S3 (denoted as third heating zone S34, third heating zone S35, and third heating zone S36) that cooperate to form another second longitudinal heating zone 42, that is, a total of six third heating zones 3, which cooperate to form two second longitudinal heating zones 42. Three first longitudinal heating zones 41 are arranged along the length direction X between the two second longitudinal heating zones 42. The second longitudinal heating zones 42 are farther away from the center of the glass plate 1 than the first longitudinal heating zones 41. Therefore, the distribution length (i.e., length dimension L3) of each third heating zone S3 in the second longitudinal heating zone 42 is greater than the distribution length (i.e., length dimension L1 and length dimension L2) of each second heating zone S2 in the first longitudinal heating zone 41.

[0070] Specifically, the first heating zones S11, S12, S13, and S14 have the same dimensions, with a length of 435mm and a width of 180mm, and each of them has four heating structures 21 arranged along the length direction X. The first heating zone S15 has a length of 320mm and a width of 180mm, and has three heating structures 21 arranged along the length direction X. The second heating zones S21, S22, S23, S24, S25, and S26 have the same dimensions, with a length of 435mm and a width of 380mm, and each of them has two rows of heating structures 21 arranged along the width direction Y. Each row of heating structures 21 includes four heating structures 21 arranged along the length direction X, for a total of eight heating structures 21. The second heating zones S27, S28, and S29 have the same dimensions, with a length of 435mm and a width of 380mm, and each of them has two rows of heating structures 21 arranged along the width direction Y. Each row of heating structures 21 includes four heating structures 21 arranged along the length direction X, for a total of eight heating structures 21. The three heating zones S210 have the same dimensions, with a length of 320 mm and a width of 380 mm. The second heating zone S29, being close to multiple first forming control zones 11 and the center of the glass plate 1, has a smaller area than the second heating zones S27, S28, and S210, and is the same as the first heating zone S15, with a length of 320 mm and a width of 180 mm. It has three heating structures 21 arranged along the length direction X inside. The three heating zones S31, S33, S34, and S36 have the same dimensions, with a length of 550 mm and a width of 580 mm. The third heating zones S32 and S35, being close to the transverse central axis of the heating zone, have a smaller area than the third heating zones S31, S33, S34, and S36, with a length of 550 mm and a width of 380 mm.

[0071] The target temperatures for each heating zone 3 are as follows: The target temperature for the first heating zone S11 is 566℃, the target temperature for the first heating zone S12 is 566℃, the target temperature for the first heating zone S13 is 571℃, the target temperature for the first heating zone S14 is 571℃, the target temperature for the first heating zone S15 is 572℃, the target temperature for the second heating zone S21 is 567℃, the target temperature for the second heating zone S22 is 566℃, the target temperature for the second heating zone S23 is 555℃, the target temperature for the second heating zone S24 is 568℃, the target temperature for the second heating zone S25 is 564℃, and the target temperature for the second heating zone S26 is... The target temperature is 556℃. The target temperature of the second heating zone S27 is 568℃, the target temperature of the second heating zone S28 is 571℃, the target temperature of the second heating zone S29 is 578℃, the target temperature of the second heating zone S210 is 569℃, the target temperature of the third heating zone S31 is 571℃, the target temperature of the third heating zone S32 is 567℃, the target temperature of the third heating zone S33 is 572℃, the target temperature of the third heating zone S34 is 571℃, the target temperature of the third heating zone S35 is 566℃, and the target temperature of the third heating zone S36 is 572℃.

[0072] Combination Figures 5 to 9 As shown, here is a specific embodiment two: The glass plate 1 has a length of 1400mm to 1600mm and a width of 800mm to 1200mm. The two head-up display areas 112 and the information transmission area 111 of the glass plate 1 form three first forming control areas 11, while the other areas of the glass plate 1 form second forming control areas 12.

[0073] The heating zones of both heating mechanisms 2 are divided into 46 heating zones 3: It includes twelve first heating zones S1 corresponding to one head-up display area 112, arranged in three rows and four columns; twelve first heating zones S1 corresponding to another head-up display area 112, also arranged in three rows and four columns; and six first heating zones S1 corresponding to the information transmission area 111, arranged in two rows and three columns, for a total of thirty first heating zones 3. Each first heating zone 3 has only one heating structure 21 inside. Thus, when processing glass plates 1 of different sizes, multiple first heating zones 3 can be respectively located above the two head-up display areas 112 and the information transmission area 111 of the glass plate 1 to achieve partitioned heating and forming of each first forming control area 11. It also includes two second heating zones S2 that cooperate with the twelve first heating zones S1 to form a first longitudinal heating zone 41, two second heating zones S2 that cooperate with the twelve first heating zones S1 to form another first longitudinal heating zone 41, and six second heating zones S2 that cooperate with the six first heating zones S1 to form another first longitudinal heating zone 41, that is, a total of ten second heating zones S2, which cooperate with the thirty first heating zones S1 to form three first longitudinal heating zones 41, and each first longitudinal heating zone 41 corresponds to a first forming control zone 11; wherein, the first longitudinal heating zone 41 corresponding to the information transmission zone 111 is closest to the center of the glass plate 1, so the area of ​​each second heating zone S2 of the first longitudinal heating zone 41 is smaller than the area of ​​each second heating zone S2 of the other two first longitudinal heating zones 41; It also includes three third heating zones S3 that cooperate to form a second longitudinal heating zone 42 and three third heating zones S3 that cooperate to form another second longitudinal heating zone 42, that is, a total of six third heating zones S3, which cooperate to form two second longitudinal heating zones 42, and three first longitudinal heating zones 41 are arranged along the length direction X between the two second longitudinal heating zones 42.

[0074] After the glass plate 1 is bent and shaped, a glass spherical test is performed. The first forming control area 11, which is composed of a head-up display area 112, has nine spherical test points, arranged in three rows and three columns with a preset interval of 100mm, and are labeled D1 to D9 from left to right and from top to bottom respectively. The first forming control area 11, which is composed of another head-up display area 112, also has nine spherical test points, arranged in three rows and three columns with a preset interval of 100mm, and are labeled D10 to D18 from left to right and from top to bottom respectively. The first forming control area 11, which is composed of an information transmission area 111, has five spherical test points, arranged in a column with a preset interval of 100mm, and are labeled D19 to D23 from top to bottom respectively.

[0075] The test results of each spherical test point in the two head-up display areas 112 are as follows:

[0076] The vertical fluctuation of the two head-up display areas 112 is as follows:

[0077] The horizontal fluctuation of the two head-up display areas 112 is as follows:

[0078] The test results of each spherical test point in information transmission area 111 are as follows:

[0080] In addition, the second molding control area 12 has two spherical test points in each of the three first longitudinal molding areas, for a total of six spherical test points, which are numbered D24 to D29 from top to bottom and from left to right. The test results are as follows:

[0081] In summary, the glass plate bending heating forming method and equipment of the present invention divides the glass plate 1 into sections and divides the heating zone according to the sections of the glass plate 1. At the same time, by precisely controlling the temperature of each heating zone 3, the surface quality of the glass plate 1 is precisely controlled by each section, ensuring that the processing accuracy of each section of the glass plate 1 meets the requirements. While improving the local accuracy of the glass plate 1, it ensures that the processing accuracy of each section of the glass plate 1 meets the requirements, thereby satisfying the functional requirements of the glass plate 1.
