[0002] After the existing saw blades are produced, it is necessary to print tracking information such as the production batch on their surface. The current saw blades are highly dependent on manual labor when screen printing is performed, and the saw blades need to be placed on the printing table manually. When the saw blade production batch is large, if the saw blades are still placed on the printing table one by one manually, the production efficiency is greatly affected and the labor intensity is high. Summary of the invention

[0003] In view of the above defects, the purpose of the present invention is to provide a fully automatic screen printing machine with a high degree of automation, which can realize automatic film taking, film loading, printing and film unloading, and solve the problems of high labor intensity and low work efficiency in the prior art.
