Description

Technical Field

[0001] The invention relates to a glue and paint expiration reminder detection device at an aircraft assembly site, belonging to the technical field of aircraft assembly detection. Background Art

[0002] With the rapid development of the aviation industry, the manufacturing and assembly of aircraft have put forward extremely high standards for process requirements, material management and quality control. Among them, glue and paint are important materials that are indispensable in the assembly process of aircraft. Their use and management will directly affect the overall quality of the aircraft and seriously affect flight safety. However, in the actual production site, there are many types of glue and paint, and the problem of expired glue and paint also occurs, which not only affects the manufacturing quality of aviation products, but also may bring serious safety hazards.

[0003] As an important bonding and sealing material, glue and paint are widely used in the connection and fixation of various components. However, as an organic polymer material, glue and paint have a certain shelf life. The performance of expired glue and paint will change, such as increased viscosity and prolonged curing time. These changes will directly affect the use effect of glue and paint, and may lead to problems such as loose bonding and loose sealing. In aircraft assembly, these problems may cause safety hazards such as loosening and leakage of some components. In the actual site, due to the difficulty of staff in understanding the types of glue and paint, ignoring the shelf life and irregular site management, the phenomenon of expired glue and paint will occur from time to time. In addition, some on-site employees are prone to ignore the shelf life of on-site glue and paint during the use of glue and paint due to the lack of an effective reminder mechanism, thereby increasing the risk of expired use. In view of the above problems, a device for reminding and detecting expired glue and paint at the aircraft assembly site is designed and invented, which has the following important significance. Improve production safety. Through the application of the reminder device, it is possible to timely detect and remind staff of the expiration of glue and paint, avoid the safety hazards caused by the use of expired glue and paint, and thus improve the quality of aviation products and flight safety. Improve production efficiency. The reminder device can automatically manage the inventory and status of glue and paint, reduce manual intervention, reduce work intensity, and improve production efficiency. At the same time, by real-time monitoring of the activity period of glue and paint, it can avoid the extra cost and time consumption caused by the disposal of expired glue and paint. Promote digital and intelligent management. The research and development and application of reminder devices are important manifestations of digital management in the aircraft assembly process. Through real-time monitoring and data analysis of glue and paint management and usage on site, it provides strong support for production decisions. Summary of the invention

[0004] The present invention provides an aircraft assembly site glue and paint expiration reminder detection device, the main purpose of which is that the device can automatically identify and detect the types of glue and paint used in the assembly site, and determine the active period according to the type, conduct a countdown reminder, and issue a reminder when the glue and paint expire. Since the production site needs to use a variety of glues and paints, and the active period of each type of glue and paint is different, the on-site operators may miscalculate the active period of the glue and paint due to long-term work fatigue, resulting in the use of expired glue and paint beyond the expiration date. The intelligent detection device can improve the accuracy of identifying glue and paint, get rid of the objective factors that affect the judgment, avoid the safety hazards caused by the use of expired glue and paint by operators, meet the product process production requirements, and play a positive role in ensuring the quality of aviation products.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A device for reminding and detecting the expiration of glue and paint at the aircraft assembly site, as shown in the attached figure Figure 1 , Attachment Figure 2 , Attachment Figure 3 As shown, the structure part plays the role of supporting components and realizing the basic detection functions. The structure part includes a box body, a bracket, an M3 screw, a cup body, a box body cover, a self-tapping screw, etc. The display screen, a green signal light, a red signal light, a reset button, a switch button, a gravity sensor, a charging port, a charging module, a power module, a controller, and a timing module constitute the electronic control part of the detection device.

[0007] The box body, bracket, cup body and box body cover in the structural part are made of PLA material through 3D printing, and other components are made of metal. The box body is used to carry the main components of glue and paint, and complete the support and function of the electronic control part. Inside it, there are reserved positions for the display screen, green signal light, red signal light, reset button, switch button, gravity sensor, charging port, charging module, power module, controller, timing module, and realize the support function of the above components.

[0008] The main structure of the present invention is a box body, which is a square box container structure, used to place a cup body containing glue and paint, and the cup body is used to present different types of paint and glue. The cup body is placed in a fixed position in the box body, and a gravity sensor is installed at the lower position of the cup body in the box body to sense the placement of the cup body. When the operator places the cup body containing paint in the box body, the gravity sensor transmits the collected signal to the controller at the bottom of the box body. The controller uses NVIDIA JETSON OrinNano intelligent development kit. When the controller receives the signal transmitted by the gravity sensor, it can determine the specific position of the cup body placed inside the box body, and the controller can receive the image data collected by the monitor in real time. The monitor is installed on the bracket by four M3 screws, and the bracket is fixed to the box body by two M5 screws. As an information collection device, the monitor is provided with a camera and a transmission mechanism inside. The camera can be rotated horizontally and vertically through the transmission mechanism inside the monitor, and the glue and paint in all cups can be photographed. Before the detection device is applied, the monitor is first used to collect data on the color, properties and other information of various types of glue and paint. Through the hardware platform of the controller, machine vision, deep learning and other technologies are used to train the model of the collected image data and form a database. When the operator places a cup containing a certain type of glue or paint on the box, the monitor accurately locates the position of the cup and automatically shoots the paint in the cup. The monitor transmits the photographed glue and paint information to the controller, and compares it with the database in the controller to record the color, properties and other information of various types of glue and paint in real time to determine the brand information of the glue and paint in the cup. At the same time, the controller retrieves the data of the activity period and service life of the corresponding glue and paint in the database. The display screen and signal lights are designed on the side wall of the box, and the number is consistent with and corresponding to the fixed position for the cup to be placed inside the box. After the timing module receives the data information sent by the controller, the countdown information of the shelf life of a certain glue or paint is displayed on the display screen. The signal light is set in green and red. When the green signal light is on, it means that the paint in the corresponding cup is within the shelf life and can be used for on-site production. When the countdown on the display screen ends, the red signal light is on, reminding that the paint in the corresponding cup has expired and cannot be used on the plane.

[0009] The power module is designed at the lower part of the box to supply power to the monitor, display, green signal light, red signal light, and controller. The power module uses a rechargeable lithium battery with a voltage of 5.0V DC, which is convenient for repeated use. The charging module uses a TP4056 module with an output of 5.0V / 2.0A, which is used for fast charging of the power module. The charging port uses a USB MINI data interface, which can be charged directly via a data cable, which is convenient and fast.

[0010] The switch button adopts a metal self-locking switch, which is installed on the box body through a matching nut. It is used to control the power on and off of the entire system. When the switch button is turned on, all modules are powered on at the same time and are ready to start working. The reset button adopts a metal self-reset button, which is used to restart and refresh the system program, and can realize the update of timing data to zero.

[0011] A method for using a glue and paint expiration reminder detection device at an aircraft assembly site, the steps are as follows:

[0012] Step 1: Check the appearance of the device for damage, make sure there are no factors that affect the characteristics of the device, press the switch button, read the LCD screen to see if it lights up, and ensure that each button is flexible and effective, whether the LCD is clear and stable, the displayed value is not interrupted, and whether the green signal light below is bright. When using, the device should be placed on a fixed plane, and the monitoring area should ensure that it can rotate freely and without obstruction to ensure that it can collect data. The device is strictly prohibited from being bumped, and no excess materials should be placed in the device box to affect its operation and service life.

[0013] Step 2: After placing the device, first turn on the power, press the power switch button to power on the device, press the reset button to return its status to zero, then the green signal light should be on and the monitor has been activated.

[0014] Step 3: When in use, put the glue and paint to be used on site into the cup of the device. The cup will trigger the gravity sensor inside the box downward due to the influence of gravity. The monitor starts to rotate in the direction of the cup that is sensed by gravity, and the glue and paint inside are transmitted according to their status to determine what kind of glue and paint it is, judge its type, determine the model based on the processor data analysis, display the active period of the material on the display screen, activate the timing module, display the remaining validity period on the display, and activate the signal light to display the effective green prompt light.

[0015] Step 4: When the countdown ends, the value on the display returns to zero and the green indicator light automatically switches to a red indicator light, indicating that the status is exceeded and on-site staff are prohibited from using it. If you need to use it, please replace it in time.

[0016] If long-term use is required, check whether there is a large amount of excess material and on-site dust in the box before use, and regularly clean and inspect the box and monitor to ensure their functional integrity. If long-term use is not required, the device needs to be covered and stored in a fixed location for easy access to ensure its service life.

[0017] Beneficial effects of the present invention:

[0018] The aircraft assembly site glue and paint expiration reminder device of the present invention can automatically identify the type of glue and paint, detect the active period of glue and paint in real time, and issue an overdue reminder function, which effectively solves the problem of glue and paint use in the assembly process of aviation products. The device has the characteristics of intelligent management, easy operation and maintenance, etc., improves production safety, improves production efficiency, and promotes the development of digitalization and intelligence in the assembly process of aviation products.
