Referring to fig. 1, fig. 1 is a schematic diagram of a glass tempering system 10 to which the heating control method according to the present application is applied. The glass tempering system 10 includes a conveying mechanism 100, a heating device 200, a cooling device 300, a detecting mechanism 400, and a controller (not shown). Wherein the conveyor 100 may be used to carry glass 4 to be tempered. The detecting mechanism 400 is mounted on the conveying mechanism 100 and located before the heating device 200, and the detecting mechanism 400 is used for detecting the thickness dimension, the plane dimension and the position of the glass 4 relative to the conveying mechanism 100. The heating device 200 is used to heat the glass 4 to its desired target temperature to relieve internal stress of the glass 4. The cooling device 300 is used for rapidly and uniformly cooling the glass 4 so as to rapidly shrink the surface of the glass 4 and generate compressive stress, thereby achieving the purpose of toughening the glass 4. The conveying mechanism 100 is further used for driving the glass 4 placed on the conveying mechanism 100 to pass through the detecting mechanism 400, the heating device 200 and the cooling device 300, so as to ensure that the glass 4 can pass through each process in sequence, and tempering is realized.

As shown in fig. 2, the conveying mechanism 100 includes a conveying roller 3, and the conveying roller 3 is capable of traveling in a traveling direction. The glass 4 may be placed on the conveying roller 3 so that the conveying roller 3 may move the glass 4 in the traveling direction when moving. The conveying roller 3 may be provided with various glass 4 having various shapes and sizes, such as rectangular glass, round glass, trapezoidal glass, diamond glass, etc., and glass having a processing hole having a round hole or a square hole, etc.

As shown in fig. 1 and 2, the detection mechanism 400 mounted on the conveying mechanism 100 includes a planar size and positioning detection device 1 and a thickness size detection device 2. Wherein the plane size and positioning detecting device 1 is installed between the thickness size detecting device 2 and the heating device 200. The plane dimension and position detecting device 1 can detect the plane dimension of the glass 4 and the position of the glass 4 relative to the conveying mechanism 100, wherein the plane dimension of the glass 4 may include a length and a width of the glass 4, the length may be a dimension of the glass 4 in a traveling direction, and the width may be a dimension of the glass 4 perpendicular to the traveling direction. The position of the glass 4 with respect to the conveying mechanism 100, that is, the initial position of the glass 4 with respect to the conveying rollers 3 is detected. The thickness detection device 2 can detect the thickness dimension of the glass 4.

Wherein the detection mechanism 400 may be an infrared detection mechanism, a visual detection mechanism, a camera mechanism or other detection mechanism

It should be noted that, in order to ensure the quality of tempering the glass 4 and prevent the problem of the frying furnace and the edge tilting of the glass 4 during the heating process, the glass tempering system 10 may be used to simultaneously temper a plurality of glass 4 with the same thickness and similar planar dimensions, or may be used to simultaneously temper a plurality of glass 4 with the same thickness and similar planar dimensions and a plurality of glass 4 with the same planar dimensions.

As shown in fig. 3, the heating device 200 is formed with a heating chamber 200a, wherein the conveying mechanism 100 can convey the glass 4 into the heating chamber 200a for heating. The heating device 200 comprises a temperature measuring module 5 and heating modules 6 arranged on two opposite sides of the conveying mechanism 100. Wherein the heating module 6 may be used to generate heat to heat the glass 4 located in its heating zone. Illustratively, the heating module 6 may include a heating wire (not shown) for generating heat and a temperature measuring member (not shown) for detecting the temperature of the heating wire. Illustratively, the temperature sensing member may be a thermocouple connected to the heating wire. The temperature measuring module 5 can detect the surface temperature of the glass 4 in the heating chamber 200a through a detection window 5a in the heating device 200. Illustratively, the temperature measuring module 5 can be used to detect the surface temperature of one or more glasses 4 located at the oven door position in the heating device 200. Illustratively, the thermometry module 5 may be an infrared thermometry module 5. In addition, the heating apparatus 200 further includes a door for opening or closing the heating chamber 200a.

As shown in fig. 1, 2 and 3, the controller may be communicatively connected to the detection mechanism 400, the heating module 6 and the temperature measurement module 5. Wherein, the database in the controller stores various heating parameters required by the glass 4 with different plane sizes and a temperature heating gradient curve for adjusting the heating parameters when the glass 4 is transversely placed. The controller can receive various data information fed back by the detection mechanism 400, the heating module 6 and the temperature measurement module 5, so that the controller can call data in the database according to the received data information and send out corresponding instructions, and the glass tempering system 10 can effectively ensure the tempering quality of the glass 4. The controller can be a singlechip, an editable logic controller, a computer, a mobile terminal or other control structures. The controller may be communicatively coupled to the detection mechanism 400, the heating module 6, and the temperature measurement module 5 via wires, data lines, bluetooth, wireless communication network technology, or other communication means.

Referring to fig. 4, fig. 4 is a flowchart illustrating a heating control method of the glass tempering system 10 according to an embodiment of the present application, wherein the heating control method of the glass tempering system 10 according to an embodiment of the present application includes the following steps:

as shown in fig. 4, plane size information of the plurality of glasses 4 on the conveying mechanism 100 and position information of the plurality of glasses 4 with respect to the conveying mechanism 100 are acquired. The heating modules 6 in the glass tempering system 10 corresponding to the plurality of glasses 4 are determined according to the plurality of plane dimension information, the plurality of position information and the traveling distance of the conveying mechanism 100. Environmental conditions are obtained, and heating parameters of the glass tempering system 10 are obtained based on the environmental conditions and the plurality of planar dimension information. The glass 4 is heated according to the heating parameters. The conveyance mechanism 100 is controlled to move the plurality of glass 4 out of the heating chamber 200a in the glass tempering system 10.

In order to better understand the above heating control method, before the conveying mechanism 100 conveys the plurality of glasses 4 placed on the conveying roller 3 to the heating chamber 200a, the planar size information of the plurality of glasses 4 and the positional information of the plurality of glasses 4 with respect to the conveying roller 3 are detected by the detecting mechanism 400, so that the controller can acquire the planar size information of each glass 4 and the positional information with respect to the conveying mechanism 100. This allows the controller to obtain the exact position of the glass 4 in the heating chamber 200a based on the plane size information, the position information, and the travel distance of the conveying roller 3 (the travel distance can be calculated based on the travel speed and travel time of the conveying roller 3) of each glass 4 when the conveying mechanism 100 drives the plurality of glasses 4 to travel to the heating chamber 200a along the travel direction, and to determine the heating module 6 opposite to the glass 4

As shown in fig. 3, when the controller acquires the positions of the plurality of glasses 4 in the heating device 200 and the heating modules 6 opposite to the respective glasses 4, the controller can regulate the heating parameters of the heating device 200 in the glass tempering system 10 according to the environmental conditions and the acquired plurality of plane dimension information, so that the heating device 200 can heat the glasses 4 to a desired temperature. When the plurality of glasses 4 located in the heating chamber 200a are heated to a desired temperature, the conveyance mechanism 100 travels in the traveling direction, so that the conveyance mechanism 100 can move the glasses 4 located in the heating chamber 200a to a device for a next process, for example, to the cooling device 300 for cooling.

In the heating control method of the glass tempering system 10, before the glass tempering system 10 heats a plurality of glass 4 simultaneously, the plane size of each glass 4 and the initial position of each glass 4 relative to the conveying mechanism 100 are detected, so that the glass tempering system 10 can judge the specific position of the glass 4 in the glass tempering system 10 according to the plane size information and the position information of the glass 4 and the travelling distance of the conveying mechanism 100, further determine the heating module 6 corresponding to each glass 4, and accurately regulate and control the heating parameters of the glass tempering system 10 according to the environmental conditions and the plane size information of each glass 4, so that the glass tempering system 10 can heat each glass 4 to the required heating temperature according to the heating parameters, thereby ensuring the quality and stability when producing glass 4 with different plane sizes, realizing the refinement and intelligent operation of heating of the glass 4, reducing the dependence on operators, and improving the working efficiency.

In one embodiment, the environmental conditions include an ambient temperature at which the glass tempering system 10 is located and an altitude at which the glass tempering system 10 is located. Different environmental temperatures and altitudes also affect the tempering quality of the glass 4 and the stability of the glass 4 during the tempering process, so when the glass tempering system 10 is at different environmental temperatures and altitudes, the heating parameters should be adjusted according to the environmental temperatures and altitudes to ensure the tempering quality and stability of the glass 4.

In one embodiment, as shown in fig. 5, after the step of obtaining the heating parameters of the glass tempering system 10 according to the environmental conditions and the plurality of plane dimension information, the step of heating the glass 4 according to the heating parameters further comprises the steps of:

and acquiring the placing posture of the glass 4 according to the plane size information of the glass 4, acquiring a temperature heating gradient curve when the placing posture of the glass 4 is transverse, and correcting heating parameters according to the temperature heating gradient curve.

As shown in fig. 1, when the detection mechanism 400 detects the size of the planar dimension of the glass 4, the glass 4 is placed in the lateral direction when the size of the glass 4 in the traveling direction is detected to be smaller than the size perpendicular to the traveling direction. I.e. when the width dimension of the glass 4 is greater than the length dimension, the glass 4 is placed in a lateral direction. Because the transverse arrangement has a certain influence on the uniform heat absorption of the glass 4, in order to ensure that the glass 4 can absorb the heat uniformly, when the controller regulates and controls the heating parameters of the glass tempering system 10 according to the environmental conditions and the plurality of plane size information, the corresponding heating parameters are modified according to the temperature heating gradient curve so as to prevent the problems of the glass 4 frying furnace and edge warping and further ensure the quality of the glass 4 tempering.

In one embodiment, the heating parameters include a preset heating duration of the glass tempering system 10, a target temperature of the glass 4, and a set heating temperature and a set heating power of each heating module 6.

Since the temperatures at which the different plane-sized glasses 4 reach softening are different, the target temperatures of the different plane-sized glasses 4 are different. And a plurality of glass 4 with different plane sizes in the same heating process should reach the required target temperature within the similar or same heating duration so as to ensure the toughening quality of a plurality of glass 4 in the same heating process. Therefore, the heating time period required for the glass tempering system 10 to heat each glass 4 to the target temperature at full power can be calculated according to the planar dimensions of the glass 4 and the target temperature theory. So that a heating period required for the heating device 200 to heat each of the plurality of glasses 4 to the target temperature can be obtained, and the heating period can be set as a preset heating period of the glass tempering system 10. The preset heating period is understood to be a preset endothermic period of the glass 4.

When the heating parameters of the heating modules 6 are regulated and controlled, the controller calls each parameter of the heating modules 6 in the database according to the target temperature of the glass 4 opposite to the heating modules 6, the altitude where the glass tempering system 10 is located and the environment temperature where the glass tempering system 10 is located, so as to determine the set heating power and the set heating temperature of each heating module 6, thereby ensuring that each heating module 6 can heat the glass 4 opposite to the heating module 6 to the target temperature within the preset heating time. In addition, when the glass 4 in the heating module 6 is placed transversely, the controller also calls the temperature heating gradient curve to correct each parameter of the heating module 6, so as to ensure the heating uniformity of the glass 4.

In one embodiment, the preset heating duration is a heating duration required for the glass 4 with the largest planar size among the plurality of glasses 4 to be heated to the target temperature of the glass 4 under the condition that the heating module 6 opposite thereto heats at full power. When a plurality of glass 4 having different planar dimensions are simultaneously heated in the heating chamber 200a of the heating apparatus 200, if each of the heating modules 6 heats the glass 4 in a full power state, the longer the heating time period required for heating the glass 4 having a larger planar dimension to a desired target temperature. Therefore, in order to ensure that a plurality of glass 4 in the same heating process can reach a required target temperature within a similar heating duration, the preset heating duration should be a heating duration required by the glass 4 with the largest plane dimension to be heated to the target temperature of the glass 4 under the condition of full-power heating of the opposite heating modules 6. The set heating temperature and the set heating power of the other heating modules 6 should be controlled based on the preset heating time period to ensure the tempering quality of the plurality of glass 4 in the heating cavity 200a.

In one embodiment, when the heating module 6 is opposite to the plurality of glasses 4 at the same time, the set heating power of the heating wires in the heating module 6 is the heating power required for heating the glass 4 having the largest planar size among the plurality of glasses 4 opposite to the heating module 6 to the target temperature within the preset heating period. When the same heating module 6 corresponds to a plurality of glass 4 with different plane sizes, the glass 4 with small plane size can reach the required target temperature before the glass 4 with large plane size under the condition of the same heating time length and heating power. Therefore, in order to enable the plurality of glasses 4 opposing the same heating module 6 to reach the target temperature within the preset heating period, the heating power required for heating the glass 4 having the largest planar size to the target temperature within the preset heating period should be the set heating power of the heating module 6.

In one embodiment, in the step of heating the glass 4 according to the heating parameters, the following steps are further included:

and controlling the heating wires in the heating module 6 to heat the corresponding glass 4 according to the set heating temperature and the set heating power, and detecting the actual heating temperature of the heating wires.

As shown in fig. 3, the heating module 6 in the heating device 200 may heat the glass on both sides of the glass 4. Wherein, the heating of the heating module 6 is realized by heating the heating wires in the heating module 6. In order to monitor the actual heating temperature of the heating wire in real time, a temperature measuring piece connected with the heating wire can be used for detecting the actual heating temperature of the heating wire. This is advantageous for monitoring the progress of the heating process.

In one embodiment, in the step of controlling the heating wires in the heating module 6 to heat the glass 4 corresponding to the heating wires according to the set heating temperature and the set heating power, and detecting the actual heating temperature of the heating wires, the method further comprises the following steps:

when the actual heating temperature is greater than or equal to the set heating temperature, the heating wire stops heating. When the actual heating temperature is smaller than the set heating temperature, the heating wire generates heat.

As shown in fig. 3, when the temperature measuring part in the heating device 200 detects that the actual heating temperature of the heating wire is greater than the set heating temperature, the controller controls the heating wire to stop heating, so that the continuous rising of the actual heating temperature of the heating wire can be avoided, and the quality and stability of the tempering of the glass 4 are affected. When the temperature measuring piece in the glass heating device 200 detects that the actual heating temperature of the heating wire is smaller than the set heating temperature, the controller controls the heating wire to generate heat, so that the heating module 6 can heat the corresponding glass 4 at a proper temperature, the uniformity of heat absorption of the glass 4 is ensured, and the quality of tempering of the glass 4 is ensured. In addition, the actual heating temperature of the heating wires in each heating module 6 is precisely controlled, so that the plurality of glass 4 in the same heating production process can reach the target temperature in similar time, and the toughening quality and stability of the plurality of glass 4 in the same heating process are guaranteed.

In one embodiment, as shown in fig. 5, after the step of heating the glass 4 according to the heating parameters, before the step of controlling the conveyance mechanism 100 to move the plurality of glass 4 out of the heating chamber 200a in the glass tempering system 10, the steps of:

the surface temperature of one or more of the plurality of glasses 4 proximate to an oven door in the glass tempering system 10 is detected. When the surface temperature of one or more of the plurality of glasses 4 near the oven door in the glass tempering system 10 is lower than the corresponding target temperature, the heating period of the glass tempering system 10 is prolonged until the plurality of glasses 4 each reach the target temperature.

As shown in fig. 1, 2 and 3, the door in the heating apparatus 200 needs to be opened during both the conveyance of the glass 4 to the heating chamber 200a by the conveyance roller 3 and the removal of the glass 4 from the heating chamber 200a. When the oven door is opened, the temperature in the heating chamber 200a will be dissipated outwards from the oven door, which will result in a lower actual temperature in the area close to the oven door, and thus in a slower heat absorption by the glass 4 located in this area compared to other areas. Therefore, if the glass 4 is moved out of the heating chamber 200a after the actual heating period of the glass tempering system 10 is equal to the preset heating period, a portion of the glass 4, which may be located near the furnace door area, may not reach the target temperature. Therefore, before the conveying mechanism 100 moves the glass 4 in the heating cavity 200a out of the heating cavity 200a, the controller controls the temperature measuring module 5 to measure the surface temperature of one or more glass 4 close to the furnace door, and determines whether the heating time of the glass tempering system 10 needs to be prolonged until each glass in the heating cavity 200a reaches the target temperature according to the measurement result, which is beneficial to ensuring that each glass 4 in the heating cavity 200a reaches the required heating temperature before moving out of the heating cavity 200a, thereby improving the tempering quality of the glass 4. In the process of delaying the heating time, the temperature measuring module 5 detects the surface temperature of one or more glass 4 located near the furnace door area in real time, so that the controller can timely acquire the surface temperature of the glass 4 in the area, and when each glass 4 in the heating cavity 200a reaches the target temperature, the conveying mechanism 100 can timely remove the glass 4 in the heating cavity 200a, so that the situation that the glass 4 is too soft due to overlong heating time is avoided.

As shown in fig. 3, the control module may control the temperature measuring module 5 to detect the surface temperature of the glass 4 located near the door when the actual heating time period is different from the preset heating time period by a predetermined time period. The temperature measurement module 5 starts to detect the temperature of the glass 4 close to the oven door before reaching the preset heating time, so that the temperature measurement module 5 can be ensured to have enough time to acquire the surface temperature of the glass 4, and the situation that the surface temperature of the glass 4 cannot be acquired in time due to the swing of the glass 4 when the actual heating time reaches the preset heating time is avoided. In addition, when the actual heating time length is different from the preset heating time length by a preset time length, the detection window 5a is opened to enable the temperature measuring module 5 to detect the surface temperature of the glass 4, so that a large amount of heat loss in the heating cavity 200a caused by long-time opening of the detection window 5a can be avoided, and the problems of poor tempering quality of the glass 4 and deformation of the glass 4 caused by large amount of heat loss in the early heating stage can be avoided.

Illustratively, the predetermined time period may be set as desired, and may be, for example, 10s to 50s.

In one embodiment, as shown in fig. 5, before the step of acquiring the plane size information of the plurality of glasses 4 on the conveying mechanism 100 and the position information of the plurality of glasses 4 with respect to the conveying mechanism 100, the steps of:

the thickness dimension of the plurality of glasses 4 is detected. When the thickness dimension of any one of the glasses 4 is not equal to the preset thickness, an alarm signal is issued.
