[0002] The production characteristics of aerospace products with multiple varieties and small batches have led to the fact that the bonding and assembly of aerospace products are mainly done manually. In recent years, with the increase in the number of aerospace production tasks and the increase in the types of production models, the quality and efficiency of traditional manual bonding and assembly have gradually been unable to meet the production needs of products.

[0003] In the current era of rapid development and popularization of science and technology, the emergence of fully automatic dispensing machines has provided the dispensing industry with new development opportunities and space. Using the human-computer interaction control interface, you can achieve simple communication and interaction with the dispensing machine, transmit technical requirements to the controller of the equipment, issue operating instructions to it, and dispense various components. In addition, the operating status of the automatic dispensing machine can be fully and intuitively displayed, such as the number of dispensing, speed, alarm and other information. It provides great convenience for the dispensing work and promotes the development of the dispensing field. Using an automatic dispensing machine to dispense various components can greatly improve the quality and efficiency of bonding assembly.

[0004] When performing automatic dispensing, it is usually necessary to fix the product and ensure the uniqueness of each positioning. However, due to the production characteristics of aerospace products with multiple varieties and small batches, the fixing process has the following problems: First, there are many varieties of aerospace products. If multiple varieties of aerospace products need to be fixed, different special positioning devices need to be designed for different aerospace products, which increases time and production costs. It can be seen that the versatility of special positioning devices is poor and the production efficiency is low; second, the components that need to be dispensed on aerospace products are installed at a high density, and the accuracy of the dispensing position must be guaranteed during dispensing, that is, the positioning device needs to be used to ensure the uniqueness of product positioning. Existing devices do not yet have these capabilities.
