Description

Technical Field

[0001] The present invention relates to the technical field of hot air guns, and in particular to a hot air gun air outlet control method, device and system. Background Art

[0002] A hot air gun is a tool that uses the hot air blown out of the heating resistor to weld and remove components. According to the working principle of the hot air gun, the main part of the hot air gun control circuit should include temperature signal amplification circuit, comparison circuit, thyristor control circuit, sensor, wind control circuit, etc. In many fields such as electronic manufacturing and home maintenance, hot air guns are widely used as a common tool for welding, disassembling components, drying, paint removal and other operations.

[0003] Since different application scenarios have different output requirements for hot air guns, such as high-temperature and high-speed hot air is required for welding, while low-temperature and low-speed hot air may be required for disassembling devices, it is necessary to adjust the air volume and air temperature of the hot air gun. In the prior art, the hot air gun is usually moved back and forth to control the wind pressure and air temperature of the blowing object by controlling the distance between the hot air gun and the blowing object; or the hot air gun controls the air volume and temperature by manually adjusting the knob. Although the adjustment knob can solve the requirements of some application scenarios for air volume and air temperature, it is not only difficult to achieve the effect of precise control by adjusting the knob; moreover, in the process of repairing circuit boards, operators also need to use voltage and current meters, electric soldering irons, DC power supplies and other equipment. The way of adjusting the knob also increases the cumbersomeness of the operator, and it is difficult to accurately control the output of the hot air gun at different stages, thereby affecting work efficiency and welding / disassembly quality. In addition, manual adjustment may also lead to safety hazards during operation. Under long-term continuous work or high-temperature and high-pressure environments, operators may misoperate due to fatigue or negligence, resulting in failures such as overheating and short circuit of the hot air gun, and even causing serious consequences such as fire.

[0049] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. In order to avoid confusing the essence of the present invention, known methods, processes, procedures, and components are not described in detail.

[0051] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include", "comprising" and similar words should be interpreted in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to".

[0052] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0053] In order to simultaneously improve the accuracy and safety of the hot air gun's air outlet control and improve the user's applicability and ease of operation, this embodiment discloses a hot air gun's air outlet control method, please refer to Figure 1 , Figure 1 Schematic diagram of the principle of a hot air gun air outlet control system disclosed in this embodiment, the hot air gun air outlet control system includes an air gun controller 100 and a hot air gun 200, wherein the air gun controller 100 and the hot air gun 200 are two devices with independent shapes and each having independent functions, and the air gun controller 100 is signal-connected to the hot air gun 200.

[0054] In one embodiment, data interaction between the air gun controller 100 and the hot air gun 200 can be achieved with the help of hardware and existing communication protocols. At this time, the hot air gun 200 has independent air volume and air temperature control functions, that is, the hot air gun 200 can be separated from the air gun controller 100 to independently control the air outlet.

[0055] In another embodiment, please refer to Figure 1 , the mainboard circuit of the hot air gun 200 can also be integrated into the air gun controller 100. In this case, the hot air gun 200 mainly includes a blower and a heating module, that is, the function of an air duct, thereby reducing the volume and mass of the hot air gun 200, thereby facilitating the use of maintenance personnel. In this embodiment, the hot air gun 200 needs to be equipped with an air gun controller 100 for air outlet control. Of course, in some embodiments, the blower and the heating module can also be integrated into the air gun controller 100 to improve the timeliness of control. In this embodiment, an air outlet duct can be configured at the air outlet of the air gun controller 100, so as to guide the hot air output by the air gun controller 100 to the hot air gun 200, thereby providing hot air to the circuit board to be repaired.

[0056] In the specific implementation process, the hot air gun air outlet control method disclosed in this embodiment is applied to the air gun controller, please refer to Figure 2 , Figure 2 The figure is a flow chart of a hot air gun air outlet control method disclosed in this embodiment. The hot air gun air outlet control method includes: step S100, step S200, step S300 and step S400, wherein:

[0057] Step S100: presenting a wind control button to the user. In this embodiment, the wind buttons include a temperature control button and a wind volume control button. Figure 1 , the air gun controller 100 presents wind control buttons to the user, which are the key interfaces for the user to interact with the hot air gun air outlet control method. The temperature control button allows the user to adjust the temperature of the hot air blown out by the hot air gun, while the air volume control button is used to adjust the wind pressure parameter, that is, the flow rate or speed of the hot air. In the specific implementation process, the air outlet button can be presented on the touch screen, that is, a virtual button, such as an icon or a slider on the touch screen; the air outlet button can also be a physical button, such as a knob, a button, etc. When the air outlet button is a physical button, it can be regarded as always presenting the air outlet control button to the user.

[0058] In the specific implementation process, the user can directly operate these buttons to input the air output parameters. For example, rotating the temperature control knob can increase or decrease the temperature setting value, and sliding the air volume control slider can adjust the air pressure parameter.

[0059] In order to quickly and accurately adapt the use scenario of the hot air gun, in addition to directly inputting parameters, preset modes can also be provided for users to choose. These preset modes are usually designed based on common hot air gun use scenarios, such as "fast heating" and "even heating". Users only need to select the corresponding preset mode, and the air gun controller will automatically set the appropriate air output parameters. This improves the configuration efficiency of the hot air gun.

[0060] Step S100 not only provides the user with an intuitive and easy-to-use air outlet control interface, but also ensures that the user can accurately and quickly input the required air outlet parameters, which lays a solid foundation for the subsequent establishment of the corresponding relationship between the air outlet parameters and the time points and the generation of the air outlet control curve.

[0061] Step S200, in response to the air outlet parameters input by the user based on the air outlet control button, establish a correspondence between the air outlet parameters and the time point. In this embodiment, the so-called air outlet parameters include air outlet pressure parameters and air outlet temperature. In the process of establishing the correspondence between the air outlet parameters and the time point:

[0062] The air gun controller continuously monitors the air outlet parameters input by the user through the air outlet control button, which include air outlet pressure parameters (such as wind speed, air volume) and air outlet temperature; parameter reception can be real-time or triggered after the user completes the input.

[0063] For each parameter change, the air gun controller records a corresponding timestamp. This timestamp marks the specific moment when the parameter changes. The accuracy of the timestamp can be adjusted according to the application requirements, for example, it can be milliseconds, seconds, or coarser time units. The air gun controller pairs the received air output parameters with their corresponding timestamps to form a parameter-time point correspondence set. This set contains all the air output parameters entered by the user during the entire operation and their corresponding time points. The established correspondence set will be stored in the internal memory of the air gun controller for subsequent processing. The storage format can be a simple list, array, or a more complex database structure, depending on the design and implementation of the system.

[0064] In order to improve input efficiency, in an optional embodiment, the user may only need to input the wind output parameters of several discrete points, and the correspondence between two adjacent discrete points may be generated according to a preset algorithm; of course, the user may also customize the slope between two adjacent discrete points, and generate the correspondence between the wind output parameters and the time point according to the slope.

[0065] In order to ensure the safety of the air gun, in an optional embodiment, before or after establishing the corresponding relationship, the air gun controller may verify the received air output parameters, and the verification content may include the legality of the parameters (such as whether the temperature is within the heating range of the hot air gun), the smoothness of the parameters (such as whether the temperature changes too drastically), etc. If the parameters are found to be illegal or not smooth, the air gun controller may issue a warning and prompt the user to re-enter or automatically adjust to a safe range.

[0066] Step S300, generate an air outlet control curve in chronological order based on the correspondence between the air outlet index and the time point. In this embodiment, the air outlet control curve characterizes the wind pressure parameters and air outlet temperature at each time point in chronological order. In the specific implementation process, the air gun controller generates the air outlet control curve in chronological order based on the correspondence between the air outlet parameters and the time points. Specifically, the air outlet control curve can be presented in a visual manner or not presented to the user. In a specific embodiment, the air gun controller reads the set of correspondences between the air outlet parameters and the time points established in step S200 from the internal memory. Ensure data integrity and accuracy, that is, each time point has corresponding air outlet parameters (including air outlet pressure parameters and air outlet temperature). Then generate the air outlet control curve based on the preset curve algorithm. The curve algorithm should be able to generate a smooth and continuous curve based on the time points and the corresponding air outlet parameters. Common algorithms include linear interpolation, polynomial interpolation, spline interpolation, etc. According to application requirements, the most suitable algorithm can be selected. Please refer to Figure 3 , Figure 3 This is a schematic diagram of a UI interface of an air gun controller disclosed in this embodiment. After selecting a preset curve algorithm, an air control curve is drawn according to the time point and the corresponding air flow parameters. The curve can be two-dimensional (such as a time-temperature curve, a time-air volume curve) or three-dimensional (such as a time-temperature-air volume comprehensive curve). Figure 3 The two-dimensional curve is illustrated, where the red line is the time-temperature curve and the blue line is the time-air volume curve. Figure 3 The left side of the example is the vertical axis of the time-temperature curve, i.e., the temperature value; Figure 3 The right side of the example is the vertical axis of the time-air volume curve, i.e., the air volume value; Figure 3 The horizontal axis of the example is the time axis; information such as the selection of the channel "CH" is also presented below the time axis.

[0067] In order to ensure the smoothness of the air outlet control curve, the generated curve may need to be smoothed. Smoothing methods include but are not limited to moving average filtering, Gaussian filtering, etc. These methods can remove noise and jitter in the curve to make it smoother and more continuous.

[0068] Step S400, outputting the air outlet control curve to the hot air gun, so that the hot air gun automatically provides the hot air with the wind pressure parameters and the air outlet temperature corresponding to each time point to the external object according to the air outlet control curve. In the specific implementation process, the air gun controller reads the air outlet control curve data generated in step S300 from the internal memory, and performs necessary format conversion on the air outlet control curve data according to the data receiving format requirements of the hot air gun, ensuring that the converted data format is compatible with the hot air gun, so that the hot air gun can correctly parse and process. After receiving the air outlet control curve data, the hot air gun receives and parses the data, and the parsing process includes identifying the data format, extracting the time point, the air outlet pressure parameter and the air outlet temperature and other information. According to the parsed air outlet control curve data, the hot air gun starts to perform the air outlet control operation, specifically, by adjusting the working state of the heating element and the fan and other components inside the hot air gun, the hot air with the wind pressure parameters and the air outlet temperature corresponding to each time point is provided according to the curve. During the control process, the hot air gun may need to perform real-time parameter adjustment and optimization to ensure the accuracy and stability of the air outlet.

[0069] Therefore, when using the hot air gun, the user does not need to pay attention to the air outlet adjustment of the hot air gun. The hot air gun automatically outputs hot air with corresponding wind pressure parameters and air outlet temperature at each time point according to the air outlet control curve, thereby simplifying the user's operation and bringing convenience to the user's maintenance work.

[0070] In this embodiment, by presetting the air outlet control curve, the hot air gun is suitable for a variety of application scenarios such as welding and component disassembly. The user can flexibly set the air outlet curve according to specific needs to meet different work requirements. In addition, the user interface is friendly, and the user can input and edit the air outlet curve data through simple operations. At the same time, the structural design of the hot air gun is also convenient for daily maintenance.

[0071] To facilitate the user to establish a correspondence between the target time node and the target air outlet parameters, in an optional embodiment, in step S200, establishing a correspondence between the air outlet parameters and the time point includes: obtaining the target time node currently selected by the user; obtaining the target air outlet parameters corresponding to the target time node input by the user; and establishing a correspondence between the target time node and the target air outlet parameters.

[0072] When selecting the target time node, you can select it through physical buttons or through the touch screen, as follows:

[0073] In one embodiment, please refer to Figure 3 The air gun controller provides an intuitive timeline interface, where users can slide, click or drag to determine the target time node. The timeline can be linear, representing a time range from a certain start time to a certain end time, and users can freely select a time node within this time range.

[0074] In another embodiment, please refer to Figure 1 The air gun controller is equipped with a set of physical buttons, through which users can enter or select time nodes. For example, you can use the numeric buttons to directly enter time (such as minutes and seconds), or use the increase / decrease buttons to gradually adjust the time nodes on the timeline.

[0075] In a specific implementation process, after the user determines the time node, the node can be marked on the timeline interface to confirm the user's input.

[0076] When obtaining the target air output parameters corresponding to the target time node input by the user, it can also be input through physical buttons or through the touch screen, which is similar to the method of selecting the target time node and will not be repeated here. In this embodiment, the user inputs the air output parameters corresponding to the target time node, such as air output temperature, air volume, etc., through the parameter input interface of the air gun controller.

[0077] After selecting the target time node and the corresponding target air output parameters, the air gun controller stores the time node determined by the user and the input air output parameters to form a corresponding relationship set for subsequent generation of the air output control curve and control of the actual air output of the hot air gun.

[0078] In this embodiment, more flexibility and diversity are provided for users to determine the time nodes. They can make precise selections through an intuitive timeline interface or quickly set them through simple physical button inputs. This improves the user's customization ability and operational convenience of the hot air gun's air output control. At the same time, the design of the air gun controller also fully considers the user interface's friendliness and ease of use to ensure that users can easily and accurately complete the setting of time nodes and air output parameters.

[0079] In order to improve the flexibility and accuracy of the hot air gun's air outlet control, in an optional embodiment, the target time node includes an adjacent first target time node and a second target time node; establishing the correspondence between the air outlet parameters and the time points also includes: obtaining the transition slope input by the user for characterizing the air outlet control curve segment between the first target time node and the second target time node; establishing the correspondence between each time point between the first target time node and the second target time node and the air outlet parameters and the time points according to the transition slope.

[0080] In the specific implementation process, among all the target time nodes set by the user, the air gun controller identifies the adjacent first target time node and the second target time node. These two nodes are set continuously by the user on the time axis, or continuously input through physical buttons. After determining the adjacent target time nodes, the air gun controller prompts the user to enter a transition slope. This slope is used to describe the smoothness or rate of change of the air outlet control curve segment from the first target time node to the second target time node. The user can enter the transition slope through the user interface of the air gun controller, and the input method may include numeric keyboard input, slider adjustment, knob rotation, etc. In this embodiment, the so-called transition slope can be a positive number, a negative number or zero, respectively indicating that the air outlet parameter is increasing, decreasing or remaining unchanged between adjacent time nodes. Then, according to the transition slope input by the user, the air gun controller will calculate the air outlet parameters at each time point between the first target time node and the second target time node. The specific calculation method depends on the type of transition slope (such as linear, nonlinear) and other parameters set by the user (such as curve shape, acceleration, etc.).

[0081] In this embodiment, a correspondence between each time point between the first target time node and the second target time node and the air outlet parameters and time points is established based on the transition slope input by the user. This not only improves the flexibility and accuracy of the hot air gun's air outlet control, but also allows the user to customize the transition effect of the air outlet control curve segment according to actual needs, thereby meeting a wider range of application scenarios and user needs.

[0082] In order to improve the flexibility and accuracy of the hot air gun's air output control, in an optional embodiment, the air output control curve includes a temperature curve and an air pressure curve, and the temperature curve and the air pressure curve are independent of each other; in step S200, the corresponding relationship between the air output temperature and the time point, and the corresponding relationship between the air pressure parameter and the time point are obtained respectively, so as to generate the temperature curve and the air pressure curve respectively. Please refer to Figure 3, the red line is the temperature curve, and the blue line is the wind pressure curve. These two curves are independent of each other and control the air outlet temperature and wind pressure parameters of the hot air gun at different time points. As described above, the air gun controller provides a user interface that allows the user to input the air outlet temperature parameters corresponding to each time point, or allows the user to input the wind pressure parameters corresponding to each time point. The user interface may include a timeline, and the user can select or input multiple time points on the timeline, and specify an air outlet temperature and a wind pressure value for each time point, and store them as a temperature-time correspondence relationship set and a wind pressure-time correspondence relationship set, respectively. In this embodiment, the temperature curve shows the change of the air outlet temperature over time, while the wind pressure curve shows the change of the wind pressure parameter over time. In step S400, the air gun controller will read the current time point in real time according to the generated temperature curve and wind pressure curve data, and determine the air outlet temperature and wind pressure parameters corresponding to the time point according to the curve data, and realize accurate air outlet control by controlling the heating elements, fans and other components inside the hot air gun, thereby adjusting the working state of the hot air gun to achieve these parameters.

[0083] In this embodiment, by allowing the user to set the corresponding relationship between the air outlet temperature and air pressure parameters and the time point, independent temperature curves and air pressure curves are generated. This not only improves the flexibility and accuracy of the hot air gun air outlet control, but also enables the user to customize more complex air outlet control strategies according to actual needs.

[0084] In order to improve the user's intuitive understanding of the hot air gun air control process, in an optional embodiment, before step S200, it also includes: presenting the initialization air control curve in a visual manner; between step S300 and step S400, it also includes: dynamically presenting the corresponding relationship in a visual manner. Please refer to Figure 3 When the user starts the hot air gun air control program, the air gun controller will first present an initialization interface; the interface contains multiple visual elements for displaying the initial air control curve. On the initialization interface, the air gun controller will display the default air control curves, which may represent common air modes or user-preset preferences. The default curves may include temperature curves and wind pressure curves, which are displayed graphically on the interface, allowing users to intuitively see the changing trends of air parameters over time.

[0085] After the user sets the correspondence between the air output parameters and the time point (step S200), and before the hot air gun starts actual air output control (step S400), whenever the user inputs or adjusts the temperature parameters, wind pressure parameters and the corresponding time point through the user interface, the temperature curve and wind pressure curve on the interface will be updated in real time to reflect these changes.

[0086] During the execution of step S200, the user can also input the air output parameters by dragging the curve, that is, the dragging and clicking events of the user on the curve can be obtained, and the air output parameters input by the user can be determined in response to the dragging and clicking events of the user, so as to facilitate the user to intuitively and quickly adjust the air output control curve. In order to further confirm the air output parameters, when the user drags and clicks the air output control curve, the air output parameter values ​​corresponding to the time nodes can be presented in the form of specific numerical values, such as 120℃, 280℃, 410℃, 260℃, and 145m 3 / h、91m 3 / h、140m 3 / h.

[0087] In this embodiment, the initialization air outlet control curve is presented in a visual manner, and the corresponding relationship is dynamically presented in a visual manner, which not only improves the user's intuitive understanding of the hot air gun air outlet control process, but also enhances the interactive experience between the user and the controller. The user can clearly see the changes in the air outlet control curve and make precise adjustments as needed, thereby achieving more efficient hot air gun air outlet control.

[0088] In order to further reduce safety hazards, in an optional embodiment, it also includes: obtaining the sleep air volume and / or sleep temperature input by the user; in the process of executing step S400, it also includes: monitoring the position trigger event of the hot air gun triggering the designated position; when monitoring that the hot air gun is placed at the designated position, outputting a sleep signal to the hot air gun, so that the hot air gun works in the state of sleep air volume and / or sleep temperature. The details are as follows:

[0089] On the control interface of the heat gun, a special input area is designed to receive the sleep air volume and / or sleep temperature input by the user. These input areas may be presented in the form of a digital input box, a slider or a drop-down menu, etc., so that the user can set it according to actual needs. When the data of the air outlet control curve has been sent or the user triggers the end of air outlet, the heat gun can be controlled to enter the sleep mode with the sleep air volume and / or sleep temperature, thereby achieving energy saving.

[0090] In the specific implementation process, in order to further reduce safety hazards, a position sensor can be set at a specified position of the hot air gun, such as a base, a bracket or a specific area. Figure 1A position sensor is provided on the placement bracket of the hot air gun shown. The sensor may be a contact sensor (such as a micro switch), a non-contact sensor (such as an infrared sensor) or other types of sensors, which are used to detect whether the hot air gun is placed in the designated position. Once the hot air gun is placed in the designated position and the sensor is triggered, the system will immediately record the event and prepare to perform subsequent sleep operations. Specifically, when a position triggering event is detected, the control system will immediately output a sleep signal to the hot air gun and make the hot air gun work in a sleep state. For the hot air gun, after receiving the sleep signal, the hot air gun will immediately adjust its working state to meet the sleep air volume and / or sleep temperature previously set by the user; in sleep mode, the air volume and temperature of the hot air gun will drop to a low level set by the user to reduce energy consumption and avoid safety hazards such as overheating.

[0091] In this embodiment, the sleep function is organically combined with the hot air gun air outlet control method, which not only improves the energy saving and safety of the hot air gun during use, but also provides users with a more convenient and user-friendly use experience.

[0092] This embodiment also discloses a hot air gun air outlet control device, which is applied to the air gun controller. The air gun controller is connected to the hot air gun signal.

[0093] The button presentation module 100 is used to present wind control buttons to the user, and the wind buttons include a temperature control button and an air volume control button;

[0094] The relationship establishing module 200 is used to establish a corresponding relationship between the air outlet parameters and the time point in response to the air outlet parameters input by the user based on the air outlet control button, and the air outlet parameters include the air outlet pressure parameters and the air outlet temperature;

[0095] The curve generation module 300 is used to generate an air outlet control curve in chronological order according to the correspondence between the air outlet index and the time point, and the air outlet control curve represents the wind pressure parameter and the air outlet temperature at each time point in chronological order;

[0096] The curve output module 400 is used to output the air outlet control curve to the hot air gun, so that the hot air gun automatically provides hot air with wind pressure parameters and air outlet temperature corresponding to each time point to the external object according to the air outlet control curve.

[0097] In an optional embodiment, it also includes:

[0098] A sleep parameter acquisition module, used to obtain the sleep air volume and / or sleep temperature input by the user;

[0099] A monitoring module, used for monitoring a position triggering event of a hot air gun triggering a designated position during the execution of the curve output module 400;

[0100] The sleep output module is used to output a sleep signal to the hot air gun when it detects that the hot air gun is placed in a specified position, so that the hot air gun works in a sleep air volume and / or sleep temperature state.

[0102] Heat guns are used to provide hot air to external objects;

[0103] The air gun controller is connected to the hot air gun signal, and the air gun controller executes a program to implement the method disclosed in the above embodiment.

That is, the user only needs to set the air outlet curve before using the hot air gun, and the hot air gun can automatically complete the control of the entire working process without frequent manual adjustment, thereby significantly improving the work efficiency; by presetting the air outlet control curve, the hot air gun can automatically work according to the air volume and temperature set by the user, greatly improving the accuracy and stability of the control. In addition, since the user does not need to adjust the hot air gun during the use of the hot air gun (for example, in application scenarios such as welding and disassembly of components), the safety risks during the operation are effectively reduced. The air gun controller and the hot air gun are independent in form and function, and there is no need to change the user's habit of using the hot air gun independently, thereby improving the user's applicability and ease of operation. In summary, the solution of the present application simultaneously improves the accuracy and safety of the hot air gun's air output control, improves the user's applicability and ease of operation, and improves work efficiency.
