Description
Technical Field
[0001] This utility model relates to the field of four-axis robot technology, and in particular to a device that uses a four-axis robot to automatically place rivets. Background Technology
[0002] A rivet is a nail-shaped object with a cap at one end. In riveting, the parts are connected by deformation or interference fit. Therefore, rivets are used in the production process of products to improve product stability and assembly efficiency. Screws require rotation during use, which lengthens the installation time. Rivets are more convenient to install. In mass production, most products are manufactured on assembly lines. When assembling products, rivets need to be inserted into the pre-drilled mounting slots. However, when rivets are placed manually on the production line, errors are prone to occur, such as placing the wrong type of rivet or missing one or two from the product, which leads to poor quality during subsequent assembly. Traditional equipment can only place a single rivet, reducing the efficiency of the placement. Therefore, we have redesigned a device that uses a four-axis robot to automatically place rivets.
