Description

Technical Field

[0001] The present invention relates to the field of intelligent manufacturing technology, and in particular to an automated assembly method and an automated assembly line for high-shear rivets. Background Art

[0002] Rivets are used to connect riveted parts by using their own deformation or interference. They are used in the aerospace field and generally use high shear rivets. Their product structure is as follows: Figures 1 to 4 As shown, the components of high-shear rivet products are mainly composed of a core rod, a ring, and a rivet body. The assembly process mainly relies on manual operation. The existing manual assembly method has the following main problems during the processing: during product assembly, the ring is manually inserted into the core rod, and then the rivet body is screwed into the core rod, and finally tightened on a drill press. The entire assembly process is completely manual. Due to the uncertainty of operator factors, the actual processing efficiency is very low. Although the assembly action is simple, the tightening process can easily cause the rivet body to be screwed in too tight or too loose, resulting in poor product quality consistency and reliability. At the same time, the assembly process requires multiple operators to perform collaborative processing according to the assembly steps, resulting in a large occupation of human resources and high labor costs. Since this assembly process is a labor-intensive process, it is easy to make it difficult to ensure the high-quality and timely delivery of products.

[0003] With the development of automation technology, there is an urgent need for an automated assembly line for automatic assembly, which can not only improve assembly quality and efficiency and reduce assembly costs, but also reduce the disadvantages caused by manual assembly errors and greatly reduce the labor intensity of workers, so as to improve assembly efficiency and product quality, thereby improving product production efficiency and meeting the requirements of high-quality product delivery.
