Multi-axis synchronization precise positioning Delta 15MC achievement efficient passenger car assembly line

In the production of passenger cars, the assembly process is a crucial step that comes after the body welding line. It plays a key role in ensuring the structural integrity and quality of the vehicle body. The six sides of the car must be aligned precisely, consistently, and synchronously to achieve an effective combined result, which directly impacts the final quality of the vehicle. Recently, Delta introduced a control solution based on its DVP-15MC multi-axis motion controller, enabling accurate positioning and displacement. This system has successfully helped an automotive assembly equipment manufacturer address issues with multi-axis synchronization and precise positioning, resulting in a more efficient and reliable assembly line.

In the passenger car assembly line, a common approach involves assembling the left and right side frames, using the longitudinal beam as a reference point for window alignment. The sequence might typically follow: first fixing the left (or right) side frame, then the top frame, and finally the post frame. During operation, the assembly line requires synchronized multi-axis movement and the ability to detect remote I/O disconnections with alarm signals. To support flexible production and meet customer demands, Delta provides a comprehensive solution centered around the DVP-15MC series motion controller, paired with the ASDA-A2 servo drive and ECMA AC servo motor, ensuring high precision and speed in multi-axis motion control. As shown in the image, the DVP-15MC series uses an external encoder as the main controller, along with elements like the DOP-B series Touch Screen and RTU-DNET modules. This allows real-time monitoring and adjustment of encoder positions. Up to 100 types of vehicle data can be stored and accessed at any time, with the program being modifiable and downloadable online for flexible control. Delta’s AC servo drive, the ASDA-A2 series, includes multiple motion control functions such as electronic camming and high-speed pulse position comparison. With internal position programming, it enables precise and synchronized movement of the ECMA series AC servo motors, supporting high-precision machining operations. After installation, Delta conducted detailed debugging to fully understand the movement requirements of the assembly line. They also trained customers in programming, debugging, and integrating the DVP-15MC series, achieving the necessary multi-axis synchronization and precise positioning required for the passenger car assembly line. The DVP-15MC controller, capable of controlling 24 real axes simultaneously, offers multiple motion control modes, rich ports, strong hardware expansion capabilities, and a user-friendly interface. It is expected to become a mainstream choice in the motion control market. By choosing the DVP-15MC series, manufacturers can effectively solve multi-axis synchronization challenges. Based on the PLCOpen 2.0 standard motion control library, the system is highly extensible and adaptable, meeting user control needs efficiently. Not only does this solution fulfill the customer's goals, but it also significantly reduces development time and resource consumption.
