Description

Technical Field

[0001] This invention belongs to the field of aerospace product process technology, specifically involving the precise preparation and uniform application of anti-loosening adhesive for screws during final assembly. Background Technology

[0002] Final assembly is the last step in manufacturing, and threadlocker adhesive, as an essential method for preventing screw loosening during assembly, requires efficient preparation and accurate proportions of its components. Currently, the preparation and application of multi-component threadlocker adhesives are mostly done manually, which is inefficient. Manual weighing of the adhesive components increases the likelihood of errors in calculation. Furthermore, manual application makes it difficult to precisely control the amount of adhesive applied, resulting in poor uniformity. Summary of the Invention

[0003] This invention provides an integrated design method for adhesive mixing and coating in aerospace products, which solves the problems of low efficiency in manual operation, high possibility of errors in the weight calculation of each component, and poor uniformity of adhesive applied manually.

[0004] This invention is achieved through the following technical solutions: A functional design method for integrated adhesive application and coating of aerospace products includes the following steps: Step 1: Connect the electronic scale and printer through the PLC system, and control the opening and closing of the one-way flow valve of the glue storage tank according to the signal fed back by the electronic scale; Step 2: Establish a database of the formulation ratios of each component of the anti-loosening adhesive and integrate it into the PLC system; Step 3: Create an interactive interface on the electronic scale to select the type of adhesive, display the real-time weight, and the required weight range; Step 4: Design a reciprocating stirring rod on the top cover of the adhesive mixing tank to automatically stir the components of the adhesive solution after they are mixed. Step 5: Pre-drill threaded holes of various specifications on the glue mixing can for even glue application to the screws.

[0005] This invention upgrades and modifies the electronic scale to precisely control the quality of each component of the anti-loosening adhesive, avoiding incorrect mixing ratios that could affect the final anti-loosening performance. In addition, by designing a dispensing tank with threaded holes, uniform coating of the adhesive is achieved, which can effectively improve work efficiency. Attached Figure Description

[0007] To better understand the specific implementation process of this achievement, the following section combines actual production practices and appendices. Figure 1-4 To elaborate further.

[0008] Step 1: Select the adhesive type on the dedicated electronic scale (confirm the proportions of each component). The scale interface will look like this. Figure 3 As shown; Step 2: First weigh the poor flowability component A1 according to the actual usage (due to its high viscosity and poor flowability, the weight cannot be accurately controlled). Step 3: Based on the weighed mass of adhesive component A1, automatically measure the corresponding mass of the more fluid adhesive component A2 from the storage tank; Step 4: After the various adhesive components are mixed in the mixing tank, the mixture is automatically stirred at a timed interval, maintaining a constant temperature environment during the process; Step 5: The dispensing tank has pre-set threaded holes of various sizes. Place the adhesive into the required threaded hole, then screw in the screws. Finally, unscrew the screws to achieve uniform coating of the anti-loosening adhesive on the threads. A 3D view of the dispensing tank is shown below. Figure 4 As shown; Step 6: The electronic scale can be connected to a printer to output a report on the dispensing process (mass of each component, temperature during dispensing, start time of dispensing, end time of dispensing, etc.), and the process record is saved.
