The assembly line is the double-speed chain assembly line, and the conventional automatic assembly line is the triple-speed assembly line. Advantage: When the previous station completes its assembly task, it automatically flows to the next station. It can save the time for manual transportation of products back and forth, so as to achieve the purpose of saving manpower and improve work efficiency. It can also cooperate with some positioning devices to replace the manual labor. The operating principle of the automatic assembly line: the motor drives the chain, the tooling plate moves on the line, and the total electronic control is controlled by PLC. Triple-speed assembly line, aging line, multi-layer aging line, ring aging line, LED lamp aging line, panel light aging line, street light aging line, flood light aging line. The triple-speed line can be combined with the robot to complete the combination of special stations, and can be positioned at a fixed point. The triple-speed chain runs stably, has strong flexibility, and has a wide range of applications. Its flexible operability is deeply loved by factories.
