Description

Technical Field

[0001] This case is about a heating device, especially an intelligent temperature-controlled heating device and its control method. Background Art

[0002] In industry, when workpieces need to be preheated, baked, or undergo multi-stage heat treatment, the workpieces are usually placed in a heating device such as an oven to achieve the aforementioned heat treatment operations. Generally, there is a heat source inside the heating device to controllably raise the temperature of the workpieces. However, limited by the space and structural design, the heat flow field in the baking area inside the heating device is often not uniform. For example, the workpieces located in the center of the baking area are more likely to be heated, while the workpieces located in the corners of the baking area are less likely to come into contact with the heat flow gas, resulting in an uneven heat flow field in the baking area, making the heat treatment effect of the workpieces unsatisfactory and causing a quality gap among the workpieces in the same batch.

[0003] In order to improve the temperature uniformity, in some traditional methods, the operator manually adjusts the internal mechanism of the heating device to cause changes in the heat flow field inside it and make the workpieces in different areas be heated more evenly. However, the above method needs to be carried out manually, resulting in an increase in labor costs. In addition, each time the internal mechanism of the heating device is adjusted, it must wait for the heating device to cool down before it can be carried out, resulting in too long a temperature adjustment time. Moreover, there are still errors in manual adjustment in the above implementation method, and the effect of improving the temperature rise uniformity of the workpieces in each area is limited, and the temperature difference still exists.

[0004] In view of this, it is necessary to develop an intelligent temperature-controlled heating device and its control method to improve the various deficiencies of the aforementioned conventional technologies. Summary of the Invention

[0005] The purpose of this case is to provide an intelligent temperature-controlled heating device and its control method, which can automatically and immediately adjust the temperature in each area of the baking area of the heating device to achieve the effects of shortening the temperature adjustment time, reducing the temperature difference in the heating section, improving the temperature uniformity, reducing the labor cost, increasing the production yield, and reducing the scrap products.

[0006] To achieve the above object, a relatively broad implementation mode of this case is to provide an intelligent temperature-controlled heating device, including a box body, a heating source, at least one deflector, at least one flow field adjustment mechanism, at least one environmental condition sensor and a control unit. The box body has an accommodation space. The accommodation space has a baking area. At least one deflector is arranged on one side of the baking area and is configured to direct the gas passing through the heating source to the baking area. At least one flow field adjustment mechanism is connected to at least one deflector and is configured to rotate at least one deflector relative to the baking area. At least one environmental condition sensor is used to sense at least one environmental condition data of the baking area. The control unit is signal-connected to the heating source, at least one flow field adjustment mechanism and at least one environmental condition sensor, and receives control signals and generates or extracts angle data, and correspondingly generates operation signals according to the control signals, at least one environmental condition data and the angle data to control the actuation of at least one flow field adjustment mechanism, and automatically and immediately adjusts the angle of at least one deflector relative to the baking area in response to the temperature change in the baking area.

[0007] To achieve the above object, another relatively general implementation mode of this case is to provide a control method for an intelligent temperature-controlled heating device, which is applicable to an intelligent temperature-controlled heating device. The intelligent temperature-controlled heating device includes a box body, a heating source, at least one deflector, at least one flow field adjustment mechanism, at least one environmental condition sensor and a control unit. The box body has an accommodation space, and the accommodation space has a baking area. At least one deflector is arranged on one side of the baking area and is configured to direct the gas passing through the heating source to the baking area. At least one flow field adjustment mechanism is connected to at least one deflector and is configured to rotate at least one deflector relative to the baking area. At least one environmental condition sensor is used to sense at least one environmental condition data of the baking area. At least one environmental condition sensor is a temperature sensor, and at least one environmental condition data is a temperature data. The control unit is signal-connected to the heating source, at least one flow field adjustment mechanism and at least one environmental condition sensor, and receives a control signal and generates or extracts an angle data. And according to the control signal, at least one environmental condition data and the angle data, correspondingly generates an operation signal to control the operation of at least one flow field adjustment mechanism. The control method of the intelligent temperature-controlled heating device includes the following steps: (a) The control unit receives the control signal, and the temperature sensor senses the starting temperature of the baking area in the starting state and transmits the starting temperature data to the control unit, where the control signal includes a preset target temperature; (b) The control unit divides the temperature difference between the starting temperature and the target temperature into multiple temperature intervals, and generates or extracts an angle data according to the multiple temperature intervals, where the angle data includes the specified rotation angle corresponding to each temperature interval in the multiple temperature intervals and each deflector of at least one deflector; (c) The control unit controls the heating source to act to raise the temperature of the baking area, and the temperature sensor continuously senses and provides the current temperature of the baking area to the control unit. And the control unit controls at least one flow field adjustment mechanism to rotate each deflector of at least one deflector to the specified rotation angle corresponding to the current temperature interval according to the temperature interval corresponding to the current temperature of the baking area and the angle data, until the temperature sensor senses that the temperature of the baking area rises to the next temperature interval; and (d) Repeat step (c) until the temperature sensor senses that the temperature of the baking area rises to the target temperature, and the control unit controls the heating source to stop operating or maintains the temperature of the baking area at the target temperature for a specific time.

[0037] Figure 1 A three-dimensional schematic diagram of an intelligent temperature-controlled heating device according to an embodiment of the present case Figure 2 is Figure 1 a schematic block diagram of the architecture of the intelligent temperature-controlled heating device shown. As Figure 1 and Figure 2As shown, the intelligent temperature-controlled heating device 100 (hereinafter referred to as the heating device 100) of this case can be used to place at least one workpiece P inside it to perform heat treatment operations such as, but not limited to, preheating, baking, or multi-stage on the workpiece P. The heating device 100 includes a box body 1, a heating source 2, at least one deflector 3, at least one flow field adjustment mechanism 4, at least one environmental condition sensor 9, and a control unit 5.

[0038] In this embodiment, the box body 1 has an accommodation space 11, and the accommodation space 11 has a baking area 11a. The box body 1 is preferably a box-shaped structure with heat insulation ability to maintain a constant temperature inside and prevent heat energy from leaking to the outside. In some embodiments, the box body 1 is a hexahedron structure (as Figure 1 shown), but the specific shape and structure of the box body 1 are not limited to a hexahedron, and other appropriate shapes and structures can also be incorporated for reference. The baking area 11a is a part of the accommodation space 11 of the box body 1, and the baking area 11a is the main space for performing heat treatment on the workpiece P. The heating device 100 further includes a baking carrier 6, which is used to support and carry the workpiece P and is disposed in the baking area 11a.

[0039] In this embodiment, the heating source 2 is, for example but not limited to, disposed in the accommodation space 11. The heating source 2 is, for example but not limited to, elements such as heat pipes, electric hot plates, or infrared heaters, and is configured to convert energy into heat energy to provide a heat flow to raise the temperature inside the box body 1. In one embodiment, the heating source 2 is disposed outside the accommodation space 11, where the space where the heating source 2 is disposed is fluidly connected to the baking area 11a, and the gas heated by the heating source 2 is allowed to be introduced into the baking area 11a, but this is not the limit.

[0040] In this embodiment, at least one deflector 3 is disposed on one side of the baking area 11a and is configured to direct a gas passing through the heating source 2 to the baking area 11a. The form of the deflector 3 is preferably a sheet, but this case is not limited thereto. In one embodiment, the number of deflectors 3 is multiple, and they are disposed on one side of the baking area 11a at a specific distance from each other. The specific distance between the multiple deflectors 3 can be equidistant or non-equidistant, and the multiple deflectors 3 can also be parallel or non-parallel. In this embodiment, the extending direction of one long side of at least one deflector 3 is parallel to the Z axis (i.e., the height direction of the box body 1), but this is not the limit.

[0041] In this embodiment, each flow field adjustment mechanism 4 includes a power output member 41 and a driving member 42. The power output member 41 is, for example but not limited to, a motor, which is a member capable of providing rotational power and preferably a member whose stroke can be controlled by an electrical signal. The driving member 42 is connected to the flow guiding plate 3, and the power output member 41 is connected to the driving member 42, wherein the driving member 42 is configured to transmit the power output by the power output member 41 to the flow guiding plate 3, so that the flow guiding plate 3 rotates to a specific rotation angle. In this embodiment, the extending direction of the driving member 42 is parallel to the Z-axis. In other words, the flow guiding plate 3 and the driving member 42 are connected and arranged on one side of the workpiece P perpendicular to the bottom surface of the box body 1, and the flow guiding plate 3 rotates with the axis of the driving member 42 as the rotation axis.

[0042] When it is desired to change the heat flow field of the baking area 11a of the heating device 100, the control unit 5 controls the power output member 41 to provide rotational power to the driving member 42, so as to adjust the angles of one or more flow guiding plates 3 relative to the baking area 11a by driving the driving member 42. Thereby, the heating device 100 can change the heat flow direction and distribution introduced into the baking area 11a, and can strengthen the heat flow at specific positions, specific areas or specific angles within the baking area 11a to make up for or adjust the heat received at each position or area of the baking area 11a, so as to improve the temperature uniformity of the baking area 11a and make the heat treatment quality of the workpiece P more homogeneous.

[0043] In this embodiment, the heating device 100 includes a plurality of flow guiding plates 3 and a plurality of driving members 42, and the plurality of flow guiding plates 3 and the plurality of driving members 42 are respectively arranged on one side of the workpiece P at intervals and perpendicular to the bottom surface of the box body 1, and each flow guiding plate 3 rotates with the axis of the corresponding driving member 42 as the rotation axis. However, the installation positions and arrangement directions of the flow guiding plate 3, the power output member 41 and the driving member 42 are not limited to the foregoing embodiments and can be changed according to actual application requirements.

[0044] In one embodiment, the driving member 42 is columnar, and the flow guiding plate 3 is parallel to the axial direction of the driving member 42. The flow guiding plate 3 rotates relative to the baking area 11a with the axial direction of the driving member 42 as the rotation axis. However, the shape and structure of the driving member 42 are not limited to the foregoing embodiments and can also be other suitable shapes or structures according to actual application requirements.

[0045] In one embodiment, the power output member 41 is disposed outside the housing 1, and the driving member 42 is located inside the housing 1 and is respectively connected to the flow guide plate 3 inside the housing 1 and the power output member 41 outside the housing 1. By disposing the power output member 41 outside the housing 1, the operation of the power output member 41 is prevented from being affected by the high temperature inside the housing 1, thereby increasing the service life of the power output member 41. In other embodiments, if the maximum operating temperature inside the housing 1 is lower than the maximum temperature threshold that the power output member 41 can withstand, or the power output member 41 is an element with high temperature resistance, the power output member 41 may also be disposed inside the housing 1.

[0046] As Figure 2 shown, in this embodiment, the control unit 5 of the heating device 100 is signal-connected to the heating source 2, the power output member 41 of the flow field adjustment mechanism 4, and the environmental condition sensor 9. The control unit 5 is, for example, a control circuit or a control chip having logical operation capabilities. The control unit 5 receives a control signal and generates or extracts angle data, and, based on the control signal, at least one environmental condition data of the baking area 11a sensed by the environmental condition sensor 9, and the aforementioned angle data, correspondingly generates an operation signal to control the rotation stroke output by the power output member 41, so as to automatically and immediately adjust the angle of the flow guide plate 3 relative to the baking area 11a in response to the temperature change in the baking area 11a. In this embodiment, the angle data includes the specified rotation angles corresponding to each temperature interval in a plurality of temperature intervals and each flow guide plate 3 of at least one flow guide plate 3, and its detailed content will be described later.

[0047] In one embodiment, the heating device 100 further includes a human-machine operation interface 12, which is connected to the control unit 5 and is configured for a user to control the heating device 100 or input and set data. After the intelligent temperature control function button on the human-machine operation interface 12 is pressed and executed by the user, the human-machine operation interface 12 generates a control signal and transmits the control signal to the control unit 5, and the control unit 5 generates an operation signal to control the actuation of the power output member 41. In one embodiment, the control signal includes preset parameters (such as a preset target temperature), so that the control unit 5 can control the actuation of the heating source 2 according to the target temperature of the control signal, and heat the baking area 11a to the target temperature.

[0048] For convenience of description, Figure 2The architecture block diagram of the heating device 100 shown only exemplarily illustrates a single power output member 41. In fact, the number of power output members 41 can be one or more, and is not limited thereto. In this embodiment, the flow guide plates 3 and the flow field adjustment mechanisms 4 are respectively multiple, and the number of the flow field adjustment mechanisms 4 corresponds to the number of the flow guide plates 3. The control unit 5 controls the respective rotation strokes output by the multiple power output members 41 to be independent of each other. That is, the control unit 5 can control each power output member 41 to output its respective rotation stroke, and these rotation strokes can be different from each other, partially the same, or all the same rotation strokes, so that the rotation angles of the respective flow guide plates 3 can be adjusted separately. It should be emphasized that the number and structural relationship of the flow guide plates 3 and the flow field adjustment mechanisms 4 of the heating device 100 in this case are not limited to the foregoing embodiments. In other embodiments, the heating device 100 can have multiple flow guide plates 3 and a single flow field adjustment mechanism 4, where the single flow field adjustment mechanism 4 has a power output member 41 and multiple driving members 42 whose number corresponds to the flow guide plates 3.

[0049] In this embodiment, as Figure 1 shown, the baking carrier 6 of the heating device 100 in this case is disposed in the baking area 11a. The baking carrier 6 has an air inlet 61 facing the flow guide plate 3, so that the air flow introduced by the flow guide plate 3 can smoothly enter the baking carrier 6. The baking carrier 6 has an air outlet 62 facing the heating source 2, and the position where the air outlet 62 is disposed does not have to be directly opposite to the heating source 2, as long as the air flow can finally flow toward the heating source 2. With the foregoing structure, an air flow circulation loop is formed inside the box body 1, and the heating source 2 is located in the air flow circulation loop, as Figure 1 indicated by the arrows in

[0050] In this embodiment, as Figure 1 shown, the heating device 100 in this case further includes a blowing mechanism 7, which is disposed in the box body 1. The blowing mechanism 7 is, for example but not limited to, a wind wheel or a blower, and is used to provide power to push the gas inside the box body 1 so that the gas can circulate inside the box body 1. In one embodiment, the blowing mechanism 7 is disposed between the flow paths of the heating source 2 and the flow guide plate 3, but is not limited thereto. The blowing mechanism 7 can be disposed at any place in the air flow circulation loop according to actual application requirements.

[0051] In this embodiment, the heating device 100 in this case further includes a filtering mechanism 8, which is disposed between the flow paths from the heating source 2 to the flow guide plate 3. The filtering mechanism 8 is, for example, a physical filter screen to filter pollutants such as dust particles. Alternatively, the filtering mechanism 8 can also be a chemical adsorption filter material to actively adsorb specific chemical components to prevent the workpiece P from being contaminated.

[0052] Figure 3A perspective view of an intelligent temperature-controlled heating device, which is a variation of this case. In this embodiment, the main components of the intelligent temperature-controlled heating device 200 (hereinafter referred to as the heating device 200) and the structures and functions of the components are the same as those of Figure 1 the main components of the heating device 100 shown and the structures and functions of the components are similar, except for the installation positions and arrangement directions of the flow guide plate 3, the power output member 41, and the driving member 42. Different from Figure 1 the heating device 100 shown, in the heating device 200 of this embodiment, the extending direction of one long side of the flow guide plate 3 and the extending direction of the driving member 42 are both parallel to the Y-axis (i.e., the width direction of the box body 1). In other words, the flow guide plate 3 and the driving member 42 are arranged on one side of the workpiece P at intervals and horizontally with respect to the bottom surface of the box body 1, and the flow guide plate 3 rotates with the axis of the driving member 42 as the rotation axis. Figure 1 And Figure 3 respectively show two installation methods of the flow guide plate 3, the power output member 41, and the driving member 42, and the installation methods of these components are not limited to the styles depicted in the drawings.

[0053] Please refer to Figure 2 again. In this embodiment, at least one environmental condition sensor 9 of the heating device 100 of this case is used to sense at least one environmental condition in the baking area 11a and transmit the sensed at least one environmental condition data to the control unit 5, where the at least one environmental condition data includes, for example but not limited to, temperature, air pressure, and / or humidity. The control unit 5 generates an operation signal to control the actuation of the flow field adjustment mechanism 4 according to the at least one environmental condition data of the baking area 11a provided by the environmental condition sensor 9, the set parameters of the control signal (such as the preset target temperature), and the angle data, and instantaneously and automatically adjusts the angle of at least one flow guide plate 3 relative to the baking area 11a in response to the temperature change in the baking area 11a. In one embodiment, the environmental condition sensor 9 is a temperature sensor 91 for sensing the temperature in the baking area 11a and providing the sensed temperature data to the control unit 5. The control unit 5 generates an operation signal to control the actuation of the flow field adjustment mechanism 4 according to the temperature data provided by the temperature sensor 91, the set parameters of the control signal (such as the preset target temperature), and the angle data, and instantaneously and automatically adjusts the angle of at least one flow guide plate 3 relative to the baking area 11a in response to the temperature change in the baking area 11a. Thus, on the one hand, the control unit 5 controls the heating source 2 to continuously heat up to the target temperature, and on the other hand, during the heating-up stage, it controls the flow field adjustment mechanism 4 and the flow guide plate 3 to adjust the temperature of each area in the baking area 11a, so as to achieve the effects of shortening the temperature adjustment time, reducing the temperature difference during the heating-up stage, and improving the temperature uniformity.

[0054] As Figure 2As shown, in one embodiment, the environmental condition sensor 9 includes at least one or a combination of a temperature sensor 91, a pressure sensor 92, a humidity sensor 93, and a wind speed and direction sensor 94, but is not limited thereto. The temperature sensor 91 is used to sense the temperature of the baking area 11a and provide temperature data of the baking area 11a to the control unit 5. The pressure sensor 92 is used to sense the air pressure of the baking area 11a and provide air pressure data of the baking area 11a to the control unit 5. The humidity sensor 93 is used to sense the humidity of the baking area 11a and provide humidity data of the baking area 11a to the control unit 5. The wind speed and direction sensor 94 is used to sense the wind speed and direction of the baking area 11a and provide wind speed and direction data of the baking area 11a to the control unit 5. Among them, the positions of the temperature sensor 91, the pressure sensor 92, the humidity sensor 93, and the wind speed and direction sensor 94 can be set according to the actual needs of the user, and are not limited to being set outside or inside the box body 1.

[0055] As Figure 1 and Figure 2 shown, the heating device 100 of this embodiment further includes a database 10. The database 10 is configured to store an angle data and at least one environmental condition data captured by the aforementioned environmental condition sensor 9. The angle data includes a specified rotation angle corresponding to each of the at least one deflector 3 in each of a plurality of temperature ranges. In one embodiment, the angle data is preset by the user through the human-machine operation interface 12 and stored in the database 10, and the content of the angle data can be adjusted and set through the human-machine operation interface 12. In other embodiments, the angle data is generated by the control unit 5 through an operation mode capable of deep learning. The control unit 5 generates the angle data through a deep learning operation according to the operation mode and a plurality of temperature and angle sample data. In one embodiment, the database 10 is, for example but not limited to, a local database disposed in the heating device 100 and connected to the control unit 5, or the database 10 is a cloud database (not shown) externally connected to the heating device 100 and communicable through the Internet of Things.

[0056] Figure 4 is a step flowchart of a control method for an intelligent temperature-controlled heating device according to an embodiment of the present case. As Figure 1 , Figure 2 and Figure 4As shown, the control method of the heating devices 100 and 200 in this case includes the following steps. In this embodiment, the environmental condition sensor 9 is a temperature sensor 91, and the environmental condition data can be temperature data. It should be emphasized that the environmental condition sensor 9 can also include a pressure sensor 92, a humidity sensor 93, or a wind speed and direction sensor 94 according to actual application requirements to control the heating devices 100 and 200 based on different environmental condition data.

[0057] Table 1 is a exemplary angle data table representing the relationship between the designated rotation angles of each of the plurality of flow guiding plates 3 and each of the plurality of temperature ranges.

[0058] Table 1: Angle Data

[0059]

[0060] The control method of the heating devices 100 and 200 in this case is as follows. First, step S1 is executed. The control unit 5 receives a control signal, and the temperature sensor 91 senses the temperature of the baking area 11a in the starting state and transmits the sensed starting temperature data to the control unit 5. Among them, the control signal includes a preset target temperature. In an embodiment, the target temperature is, for example, 50.0 °C, and the starting temperature is, for example, 20.0 °C. It should be emphasized that the target temperature and the starting temperature are not limited to this. The target temperature can also be between 40.0 °C and 250.0 °C, and the starting temperature can also be between 10.0 °C and 30.0 °C.

[0061] Next, step S2 is performed. The control unit 5 divides the temperature difference between the starting temperature and the target temperature into multiple temperature intervals, and generates or extracts an angle data according to the multiple temperature intervals, where the angle data includes the specified rotation angles corresponding to each of the multiple temperature intervals and at least one deflector 3 of the deflectors 3. In this embodiment, the control unit 5 extracts the required data from the data preset and stored in the database 10 according to the multiple temperature intervals, so as to generate the angle data (as shown in Table 1). In one embodiment, the control unit 5 divides the temperature difference between the starting temperature (for example, 20.0 °C) and the target temperature (for example, 50.0 °C) into three temperature intervals, namely 20.0 °C to 29.9 °C, 30.0 °C to 39.9 °C, and 40.0 °C to 50 °C. The control unit 5 extracts the required data from the data preset and stored in the database 10 according to the three temperature intervals, so as to generate the angle data (as shown in Table 1), where the angle data includes the specified rotation angles corresponding to each of the five deflectors 3 in each of the three temperature intervals. For example, the specified rotation angle of the first deflector 3 in the temperature interval of 20.0 °C to 29.9 °C is 90 degrees, and the specified rotation angle of the fifth deflector 3 in the temperature interval of 40.0 °C to 50 °C is 9 degrees.

[0062] Next, step S3 is performed. The control unit 5 controls the heating source 2 to raise the temperature of the baking area 11a, and the temperature sensor 91 continuously senses and provides the current temperature data of the baking area 11a to the control unit 5. The control unit 5 controls at least one flow field adjustment mechanism 4 to rotate each deflector 3 to the specified rotation angle corresponding to the current temperature interval according to the temperature interval corresponding to the current temperature of the baking area 11a and the angle data, until the temperature sensor 91 senses that the temperature of the baking area 11a has risen to the next temperature interval. As shown in Table 1, when the temperature sensor 91 senses that the current temperature of the baking area 11a is between 20.0 °C and 29.9 °C, the control unit 5 controls the flow field adjustment mechanism 4 to rotate the first deflector 3 to the specified rotation angle (for example, 90 degrees) corresponding to the temperature interval of 20.0 °C to 29.9 °C according to the current temperature interval and the foregoing angle data, until the temperature sensor 91 senses that the temperature of the baking area 11a has risen to the temperature interval of 30.0 °C to 39.9 °C. At the same time, the control unit 5 controls the flow field adjustment mechanism 4 to rotate the second deflector 3 to the specified rotation angle (for example, 90 degrees) corresponding to the temperature interval of 20.0 °C to 29.9 °C according to the current temperature interval and the foregoing angle data, until the temperature sensor 91 senses that the temperature of the baking area 11a has risen to the temperature interval of 30.0 °C to 39.9 °C. In addition, the third deflector 3, the fourth deflector 3, and the fifth deflector 3 are also implemented in a similar manner, which will not be elaborated here.

[0063] Finally, step S4 is executed, and step S3 is repeated until the temperature sensor 91 senses that the temperature in the baking area 11a has risen to the target temperature (e.g., 50.0 °C), and then the control unit 5 controls the heating source 2 to stop operating or maintains the baking area 11a at the target temperature for a specific period of time. As shown in Table 1, in this step, when the temperature sensor 91 senses that the temperature in the baking area 11a has risen to the temperature range of 30.0 °C to 39.9 °C, the control unit 5 controls the flow field adjustment mechanism 4 to actuate according to the current temperature range and the aforementioned angle data, so as to rotate the first deflector 3 to the rotation angle corresponding to the temperature range of 30.0 °C to 39.9 °C (e.g., 130 degrees) until the temperature sensor 91 senses that the temperature in the baking area 11a has risen to the temperature range of 40.0 °C to 50.0 °C. At the same time, the control unit 5 controls the flow field adjustment mechanism 4 to actuate according to the current temperature range and the aforementioned angle data, so as to rotate the second deflector 3 to the specified rotation angle corresponding to the temperature range of 30.0 °C to 39.9 °C (e.g., 120 degrees) until the temperature sensor 91 senses that the temperature in the baking area 11a has risen to the temperature range of 40.0 °C to 50.0 °C. In addition, the third deflector 3, the fourth deflector 3, and the fifth deflector 3 are also implemented in a similar manner, which will not be elaborated here.

[0064] After that, when the temperature sensor 91 senses that the temperature in the baking area 11a has risen to the temperature range of 40.0 °C to 50.0 °C, the control unit 5 controls the flow field adjustment mechanism 4 to actuate according to the current temperature range and the aforementioned angle data, so as to rotate the first deflector 3 to the rotation angle corresponding to the temperature range of 40.0 °C to 50.0 °C (e.g., 171 degrees) until the temperature sensor 91 senses that the temperature in the baking area 11a has risen to the target temperature (e.g., 50.0 °C). At the same time, the control unit 5 controls the flow field adjustment mechanism 4 to actuate according to the current temperature range and the aforementioned angle data, so as to rotate the second deflector 3 to the specified rotation angle corresponding to the temperature range of 40.0 °C to 50.0 °C (e.g., 135 degrees) until the temperature sensor 91 senses that the temperature in the baking area 11a has risen to the target temperature (e.g., 50.0 °C). In addition, the third deflector 3, the fourth deflector 3, and the fifth deflector 3 are also implemented in a similar manner, which will not be elaborated here. When the temperature sensor 91 senses that the temperature in the baking area 11a reaches the target temperature (e.g., 50.0 °C), the control unit 5 controls the heating source 2 to stop operating, or controls the baking area 11a to maintain at the target temperature for a specific period of time.

[0065] According to the control method of the present case, the heating devices 100 and 200 of the present case can automatically and instantaneously adjust the angle of each deflector 3 relative to the baking area 11a in response to the temperature change of the baking area 11a, thereby introducing the heat flow introduced into the baking area 11a through the heat source 2 into a specific area of the baking area 11a in a shunted and dynamically adjustable angle manner, and changing the heat flow field distribution and direction within the baking area 11a to compensate for or adjust the heat reception uniformity of each position or area in the baking area 11a, so that the heat treatment quality of the workpiece P is closer to homogenization.

[0066] In an embodiment, the control signal further includes a preset target time, and the control unit 5 controls the heating power of the heat source 2 according to the preset target time, so that the baking area 11a reaches the target temperature within the target time. For example, if the target time included in the control signal is 5 minutes and the target temperature is 50 °C, then the control unit 5 controls the heat source 2 to heat to a specific power, so that the baking area 11a reaches the target temperature (i.e., 50 °C) within the target time (i.e., 5 minutes). In an embodiment, the target time is preferably between 2 minutes and 10 minutes, but not limited thereto.

[0067] In an embodiment, the temperature interval of each temperature interval divided by the control unit 5 is preferably between 1.0 °C and 30.0 °C, and each temperature interval can be equal or unequal, but not limited thereto, and it can be arbitrarily changed according to actual needs. In this embodiment, the temperature interval of each temperature interval is 10.0 °C, but not limited thereto.

[0068] In summary, the present case provides an intelligent temperature-controlled heating device and its control method, which can change the heat flow distribution and direction in the baking area, can strengthen the heat flow at specific positions and angles, to compensate for or adjust the heat reception of each position and area in the baking area, so that the heat treatment quality of the workpiece is closer to homogenization. In addition, the intelligent temperature-controlled heating device and its control method of the present case can achieve the effects of shortening the temperature adjustment time, reducing the temperature difference in the heating section, improving the temperature uniformity, reducing the labor cost, increasing the production yield and reducing the scrap rate.

[0069] This case can be variously modified by those skilled in the art, but all are not beyond the scope of protection as claimed in the appended claims.
