Description

Technical Field

[0001] The invention relates to the field of machinery, and in particular to a screw rivet conveying device. Background Art

[0002] As all walks of life are gradually adopting the trend of automated production or assembly, automatic assembly robots are also widely used in different industries. Among them, the transportation and nailing of rivets are an indispensable link. The transportation in the prior art basically adopts the method of using a driver to drive the entire preset track and storage device to vibrate to achieve the transportation of rivets. This more commonly used solution has many disadvantages. In order to achieve the transportation of rivets, the entire mechanism needs to be fixed on a base that is large enough and stable enough. This has relatively high requirements for assembly space and site for miniaturized automatic assembly robots and certain precision instrument assembly, and it is difficult to meet the requirements of lightweight and integrated equipment. At the same time, the moving distance of the robotic arm will increase relatively, which will increase the process and time of transportation and assembly, resulting in unnecessary waste. The vibration of the entire machine will also cause the accuracy of the machine to decrease, resulting in an increase in the cost of the entire machine and even production. Summary of the invention
