Description

Technical Field

[0001] This utility model belongs to the field of aircraft maintenance technology, specifically relating to a paint spraying heating control and monitoring device for aircraft maintenance. Background Technology

[0002] In aircraft maintenance painting processes, the post-painting curing process is a crucial factor affecting coating performance. Current heating equipment lacks real-time temperature monitoring and intelligent control, leading to uneven drying, poor adhesion, and even problems like bubbles or cracks. These issues significantly impact the appearance quality and lifespan of aircraft components. Furthermore, existing equipment still has room for improvement in terms of ease of operation and temperature control accuracy, making it difficult to fully meet the demands of high-quality painting processes. Utility Model Content

[0003] To overcome the lack of real-time temperature monitoring and intelligent control capabilities in existing aircraft maintenance painting processes, which leads to uneven coating drying, poor adhesion, and the formation of bubbles or cracks, this invention provides a painting heating control and monitoring device for aircraft maintenance. This device uses a multi-point temperature acquisition module to accurately monitor the temperature inside the heating chamber. A controller adjusts the power output of the heating module group in real time based on the collected temperature data. Simultaneously, a fan assembly ensures uniform heat distribution, guaranteeing that the paint coating achieves ideal drying and adhesion performance during the curing process.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A painting heating control and monitoring device for aircraft maintenance mainly includes a support platform, a heating chamber, a heating module group, a conical air guide, a multi-point temperature acquisition module, an air guide assembly, a controller, and a display and operation panel. The support platform is equipped with casters at its bottom for easy movement of the entire device; the heating chamber is fixed to the support platform by clamps, and its top is equipped with a removable cover; the heating module group is detachably installed inside the heating chamber, located at the bottom end of an air inlet on the side wall of the heating chamber, for heating the incoming air before sending it into the chamber; four air outlets are evenly distributed at the bottom of the heating chamber for discharging the heated gas and maintaining pressure balance within the chamber; the conical air guide is connected to the interior of the heating chamber via a flexible hose, and has a handle for easy adjustment by the operator to change the airflow direction; the sensor probe in the multi-point temperature acquisition module passes through the heating chamber... The cavity interlayer of the heating chamber extends into the interior, and sensors are fixed on the heating chamber to transmit the collected temperature signals to the controller. The air guide assembly is installed on the support platform and includes a fan and an air inlet pipe. The fan is installed on one side of the support platform, and one end of the air inlet pipe passes through the heating chamber and connects to its interior, while the other end connects to the air outlet of the fan, for introducing outside air into the heating chamber. The controller is installed on one side of the support platform and is connected to the multi-point temperature acquisition module, the heating module group, and the air guide assembly via signal lines, for receiving temperature signals and regulating the heating module group. The display and operation panel is embedded above the controller for displaying temperature data and the operation interface.

[0005] A filter layer is installed at the air inlet of the fan. The filter layer is composed of multiple layers of fiber material and is used to intercept particulate matter in the air and prevent it from entering and contaminating the heating chamber.

[0006] The heating module group includes multiple independent heating tubes and a guide fan. Each independent heating tube consists of a heating wire and heat dissipation fins. The heating wire is embedded in the heat dissipation fins. The guide fan is installed at the top of the heating tube and the heat dissipation fins to blow the heated air into the heating chamber. The heating tubes are electrically connected to the controller through wires. The controller adjusts the power output of each independent heating tube according to the signal fed back by the temperature acquisition module, thereby achieving precise control of the temperature inside the chamber.

[0007] Each sensor probe in the multi-point temperature acquisition module is made of high-temperature resistant material and wrapped with a thermally conductive silicone sleeve. The thermally conductive silicone sleeve is fixed to the sensor probe with adhesive to improve the sensor's thermal conductivity and durability. The sensor probe is connected to the controller via a signal line, and the controller generates corresponding control commands based on the received temperature signal.

[0008] The working principle of this invention is as follows: When the device is started, the operator sets the target temperature range through the display control panel, and the controller adjusts the heating module group according to the set value. A fan introduces external air into the air inlet duct, which then passes through a filter layer and enters the heating chamber. The heating wires in the heating module group begin to operate, heating the air to the set temperature range. The heated air is evenly distributed inside the heating chamber by the guide fan, while the conical guide shroud can be adjusted as needed to guide the airflow to cover the surface of the parts to be treated. Sensor probes in the multi-point temperature acquisition module monitor the temperature at different locations inside the chamber in real time and transmit the collected data to the controller. The controller dynamically adjusts the power output of each independent heating element in the heating module group based on the temperature data, ensuring that the temperature inside the chamber remains within the set range.

[0009] The beneficial effects of this utility model are:

[0010] This invention uses a multi-point temperature acquisition module to monitor the temperature at different locations inside the heating chamber in real time. The controller dynamically adjusts the power output of the heating module group based on the collected temperature data, solving the problem of poor coating drying effect caused by uneven temperature in traditional equipment. The heating module group evenly distributes the heated air inside the chamber, avoiding local overheating or undercooling and improving coating adhesion and appearance quality. The filter layer at the fan inlet effectively intercepts particulate matter in the air, reducing contamination of the component surface. The casters at the bottom of the support platform make the device easy to move and improve the convenience of operation. In summary, this invention, through the coordinated operation of the multi-point temperature acquisition module, heating module group, air guide assembly, and other components, achieves precise control of the heating and curing process of the spray paint coating, significantly improving the drying uniformity and adhesion performance of the coating, and meeting the requirements of high-quality spray painting processes.

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0019] This utility model discloses a paint spraying heating control and monitoring device for aircraft maintenance. The paint spraying heating control and monitoring device for aircraft maintenance mainly includes a support platform 1, a heating chamber 2, a heating module group 3, a conical air guide 4, a multi-point temperature acquisition module 5, an air guide assembly 6, a controller 7, and a display and operation panel 8. Figure 1 In this structure, the support platform 1 serves as the foundation for the entire device. Four casters 9 are evenly distributed at the four corners of the support platform 1, allowing for flexible movement and positioning of the device. The heating chamber 2 is fixed to the center of the upper surface of the support platform 1 by clamps. A removable cover 10 is provided on the top of the heating chamber 2, facilitating cleaning and maintenance of the interior and heating module assembly 3 by operators. Air inlets are located on the side walls of the heating chamber 2, and the heating module assembly 3 is bolted to the bottom of the air inlets to heat external air before introducing it into the heating chamber 2. Four air outlets 11 are evenly distributed at the bottom of the heating chamber 2 to discharge heated gas and maintain pressure balance within the chamber.

[0020] like Figure 4 , Figure 5 , Figure 6 As shown, the heating module group 3 is fixed inside the heating chamber 2 by bolts, and its air intake direction corresponds to the air inlet of the heating chamber 2 to ensure that air can smoothly enter the heating module group 3 for heating. The heating module group 3 consists of multiple independent heating tubes 16 and a guide fan 17. Each independent heating tube 16 includes a heating wire and heat dissipation fins. The heating wire is embedded in the heat dissipation fins and is electrically connected to the controller 7 through a wire. The guide fan 17 is installed at the top of the heating tubes 16 and the heat dissipation fins to blow the heated air into the heating chamber 2.

[0021] like Figure 4 , Figure 5As shown, the sensor probe in the multi-point temperature acquisition module 5 extends into the interior through the cavity interlayer of the heating chamber 2. The sensor probe is wrapped with a thermally conductive silicone sleeve and fixed with adhesive. The sensor probe is connected to the controller 7 through a signal line to realize the transmission of temperature data.

[0022] like Figure 4 , Figure 5 As shown, the conical air guide 4 is connected to the interior of the heating chamber 2 through a flexible hose 12. One end of the flexible hose 12 is fixed to the bottom of the air outlet 11 of the heating chamber 2, and the other end is connected to the conical air guide 4. A handle is provided on the outer wall of the conical air guide 4 to facilitate the operator to adjust its position to change the airflow direction.

[0023] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the air guide assembly 6 is installed on one side of the support platform 1, including a fan 14 and an air inlet pipe 15. The fan 14 is installed on the support platform 1. One end of the air inlet pipe 15 passes through the heating chamber 2 and communicates with its interior, while the other end communicates with the air outlet of the fan 14, for introducing external air into the heating chamber 2. A filter layer 13 is installed at the air inlet of the fan 14. The filter layer 13 is composed of multiple layers of fiber material, used to intercept particulate matter in the air and prevent it from entering the heating chamber 2 and contaminating the interior of the heating chamber 2 and the surface of the parts to be treated.

[0024] The controller 7 is mounted on the support platform 1. The controller 7 is connected to the multi-point temperature acquisition module 5 and the heating module group 3 via signal lines, respectively, to receive temperature signals and regulate the heating module group 3. The display and operation panel 8 is embedded above the controller 7. The display screen and buttons of the display and operation panel 8 face outwards for easy viewing of temperature data and setting operations by the operator. The display and operation panel 8 is connected to the controller 7 via a ribbon cable and is used to display temperature data and the operation interface.

[0025] When the device is started, the operator sets the target temperature range via the display control panel 8, and the controller 7 adjusts the heating module group 3 according to the set value. The fan 14 introduces external air into the air inlet duct 15, which then passes through the filter layer 13 and into the heating chamber 2. The heating wires in the heating module group 3 begin to operate, heating the air to the set temperature range. The heated air is evenly distributed inside the heating chamber 2 under the action of the guide fan 17, while the conical guide shroud 4 can be adjusted as needed to guide the airflow to cover the surface of the parts to be treated. The sensor probes in the multi-point temperature acquisition module 5 monitor the temperature at different locations inside the chamber in real time and transmit the collected data to the controller 7. The controller 7 dynamically adjusts the power output of each independent heating tube 16 in the heating module group 3 based on the temperature data, ensuring that the temperature inside the chamber remains within the set range. The heating wires in the heating module group 3 achieve power output changes through the adjustment of the controller 7, thereby precisely controlling the temperature inside the heating chamber 2. The length and flexibility of the flexible hose 12 allow the conical airflow deflector 4 to move freely within a certain range. Operators can adjust the position of the conical airflow deflector 4 using handles to ensure that the airflow direction covers a specific area of ​​the component to be treated. Sensor probes in the multi-point temperature acquisition module 5 are distributed at different heights and positions within the heating chamber 2, ensuring comprehensive and accurate temperature monitoring. The controller 7 analyzes the temperature data and generates corresponding control commands, which are transmitted via signal lines to the individual heating tubes 16 in the heating module group 3, achieving precise temperature control. The display screen of the operation panel 8 shows the temperature data inside the heating chamber 2 in real time. Operators can adjust the target temperature range or view historical temperature records using buttons.

[0026] Work process:

[0027] I. Preliminary Preparations

[0028] The staff moved the device to a suitable position next to the aircraft maintenance and painting parts using the casters 9 at the bottom of the support platform 1. The aircraft parts to be heated and cured were placed in the appropriate position, and the conical airflow deflector 4 was connected to the air outlet 11 at the bottom of the heating chamber 2 via the flexible hose 12, allowing the hot airflow to be accurately directed to the painted parts. Simultaneously, the staff checked the stability of all connections, ensuring that the heating module group 3, multi-point temperature acquisition module 5, fan 14, and other components were electrically connected to the controller 7. The display control panel 8 was then opened to initialize the device.

[0029] II. Heating and Air Supply Process

[0030] Start the fan 14: The operator sends a command to the controller via the display panel 8, and the controller 7 controls the fan 14 to start. When the fan 14 is working, outside air enters through the air inlet. Because the air inlet of the fan 14 is equipped with a filter layer 13 made of multiple layers of fiber material, the air is filtered before entering the fan 14 to remove dust, impurities, etc., ensuring that the air entering the heating chamber 2 is clean and avoiding contamination of the paint coating.

[0031] Air enters heating chamber 2: Filtered air enters heating chamber 2 through air inlet pipe 15.

[0032] Heating the air: Controller 7 controls the heating module group 3 to start working. Multiple independent heating tubes 16 in the heating module group 3 begin to heat up. Each independent heating tube 16 consists of a heating wire embedded in a heat sink fin. The heating wire generates heat when energized, and the heat is dissipated into the surrounding air through the heat sink fins. Simultaneously, a guide fan 17 is installed at the top of the heating tubes 16 and the heat sink fins. Its function is to quickly and evenly blow the heated air into the heating chamber 2, allowing the air to mix thoroughly and heat up within the heating chamber 2.

[0033] Hot airflow directed to paint components: After the heated air is heated in the heated chamber 2, it flows out through four air outlets 11 evenly opened at the bottom of the heated chamber 2, enters the conical guide shroud 4 through the flexible hose 12, and finally the conical guide shroud 4 directs the hot airflow to the paint components of the aircraft maintenance, so as to heat and cure the paint.

[0034] III. Temperature Monitoring and Control Process

[0035] Temperature Acquisition: The sensor probes in the multi-point temperature acquisition module 5 play a crucial role. These sensor probes extend into the interior through the cavity interlayer of the heating chamber 2, and are covered with a thermally conductive silicone sleeve and fixed with adhesive. This ensures accurate temperature acquisition by the sensor probes while also providing a degree of protection. The sensor probes collect temperature information from different locations within the heating chamber 2 in real time and transmit this temperature data to the controller 7 via signal lines.

[0036] Intelligent Control: After receiving temperature data from the multi-point temperature acquisition module 5, the controller 7 compares and analyzes it with the preset temperature range. If the acquired temperature is lower than the set range, the controller 7 increases the power supply to the independent heating tubes 16 in the heating module group 3 to generate more heat. It may also appropriately increase the speed of the guide fan 17 and the fan 14 to accelerate the circulation and delivery of hot air. If the acquired temperature is higher than the set range, the controller 7 reduces the power supply to the independent heating tubes 16 to decrease heat generation, and may even temporarily stop the operation of some independent heating tubes 16. Simultaneously, it adjusts the speed of the fan 14 and the guide fan 17 to lower the temperature. Through this real-time monitoring and intelligent control, the painted parts are ensured to be in a suitable temperature environment during the heating and curing process, avoiding problems such as uneven coating drying, poor adhesion, bubbles, or cracks.

[0037] IV. User Interaction and Display

[0038] Throughout the entire operation, the display control panel 8 plays a crucial interactive role. Operators can view the real-time operating status of the device on the display control panel 8, including the operating power of the heating module group 3, the speed of the fan 14, and temperature data collected at various locations by the multi-point temperature acquisition module 5. Simultaneously, operators can also use the display control panel 8 to set various parameters and input operating commands, such as setting the target temperature range and adjusting the speeds of the fan 14 and the guide fan 17, enabling convenient and quick control and management of the device.

[0039] V. End of work

[0040] After the heating and curing process of the painted parts is completed, the operator sends a stop command to the controller 7 via the display panel 8. The controller 7 then shuts down the heating module group 3, the fan 14, and other equipment in sequence. The conical air guide shroud 4 and the flexible hose 12 are then placed on the support platform 1 to prepare for the next operation.

[0041] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
