Delta SCARA Robot for Fan Assembly Line – Excellent Flexible Automated Manufacturing
Traditional manufacturing relies heavily on manpower, which often results in inconsistent performance, high labor costs, and other problems. However, smart manufacturing is able to solve these issues through improving overall productivity, reducing production time and providing a variety of products as well as flexible production lines to meet market demands. For fan assembly lines, Delta's SCARA robot matched with peripheral devices such as the Delta machine vision system DMV Series offers precise detection for product loading positions with simple manufacturing steps to enhance monitoring the management and production process.
Delta's SCARA Robot DRS60L Series has been successfully applied to fan assembly lines at Delta's Wujiang Plant in Mainland China. The DRS60L Series integrates with the robot controller DCS Series and programmable logic controller DVP Series for procedure setup and control to achieve flexible and automated manufacturing. In addition, this robot workstation employs key components including the machine vision system DMV1000 Series and Human Machine Interface DOP-B Series to collect and display all equipment data via high speed Ethernet communication so equipment operators can manage the whole operation. As a result, this workstation also reduces human error and optimizes overall production efficiency.
The workstation for the Delta fan assembly line employs a total of three SCARA robots with three machine vision system DMV1000 Series to assemble components for the fan platform including fan blades, bearings to support rotation around a fixed axis or linear movement with less friction, and springs. The whole automated production line begins with loading fan blades onto the conveyor belt. The fan blade then proceeds to the first SCARA robot station, where the DMV1000 Series detects its fixed position and the robot picks and places the bearing precisely onto the blade for completion. Next, the fan blade moves to the second SCARA robot station for fan frame assembly and continues to the last SCARA robot station for the final assembly stage of placing spring and upper bearings onto the fan blade.
The solution successfully adopts Delta SCARA robots for different operations at the same workstation. Benefits include:
• Excellent speed, repeatability, linearity, verticality and a sensor-less compliance control function to compensate for the deviation between work pieces and insertion holes. This function also allows SCARA to precisely complete assembly demands.
• Matching up with the machine vision system DMV1000 Series for precise product positioning and quick positioning adjustment.
• Matching up with the Human Machine Interface DOP-B Series for real-time equipment data and condition display, which allows equipment operators to easily manage the workstation.
• Intuitive software interface that provides simple programming steps and is easy to operate.
• The robot workstation that reduces the use of fixtures and improves overall production efficiency.
Delta's SCARA robot solution has been successfully applied to fan assembly production lines and other precision assembly. In addition, the solution enhances equipment and productivity, saves manufacturing cost, improves company competitiveness and achieves flexible as well as smart manufacturing demands.
