The general direction of the manufacturing industry in the 21st century is the automation of machinery and equipment. At the same time, rubber synchronous belt production lines are becoming more flexible. Because the current investment in the robot industry is increasing, it will help us free human physical labor. Therefore, automated production lines and processing equipment with highly automated procedures will be a new ray of sunshine in the 21st world. In the future, single and ordinary special processing will be replaced by fully automatic production lines. Many parts, including timing belts, have been transferred abroad, and many countries have already achieved the automation goal, especially the production of robots in developed countries such as Europe and the United States has been completely automated. Although it is the interconnection between them, the cogging between them must be corresponding. If they are not fully calculated, deviations will occur, so it is very important in production and installation, especially when it is produced. They need to be connected to each other. Among them, the pitch, tooth height, and belt thickness must be measured, and the manufacturing needs to be accurate. The pace of the installation is also critical.
