In the passenger car production process, the assembly process is the first step of the body welding assembly line, and it is the most critical process in the production of the passenger car body. The six faces of the passenger car must be synchronized, stable and precise, and the combined effect is also effective. Will directly affect the final vehicle quality.
Recently, Delta has provided a control solution based on the multi-axis motion controller DVP-15MC series, which can achieve accurate positioning and displacement. It has successfully helped a manufacturer of automotive assembly line equipment solve multi-axis synchronization and precise positioning. The entire assembly line runs efficiently.

In the passenger car assembly line, the commonly used assembly process is the left and right side of the skeleton assembly, respectively, with the window on the longitudinal beam as a positioning reference point. The fitting order may be arranged in the following manner: fixed left (right) side frame assembly → fixed top frame assembly → fixed (post) frame assembly.
In the operation of the assembly line, it is required to implement multi-axis synchronous positioning movement, and at the same time, it is required to detect that the remote I/O is disconnected and there is an alarm. In order to achieve flexible production and meet customer needs, Delta provides multi-axis motion controller DVP-15MC series as the core, with servo drive ASDA-A2 series, AC servo motor ECMA series and other components composed of high-precision, high-speed multi-axis Motion control program.
As shown in the figure, Delta's multi-axis motion controller DVP-15MC series is equipped with an external encoder as the main controller, with DOP-B series and other control elements (RTU-DNET remote DeviceNET module, DeviceNet master module, etc.) ), It can monitor and modify the position of the encoder. At least 100 types of vehicle data can be stored in the touch screen and can be called at any time. The program can be modified and downloaded online to achieve flexible motion control.
In terms of motion control, Delta uses AC servo drive ASDA-A2 series, built-in multiple motion control functions (such as electronic cams, high-speed pulse position acquisition comparison, etc.) and internal position programming mode, which can accurately control the AC servo motor The ECMA series performs high-precision, high-speed, simultaneous motion with high precision and high speed to achieve precise machining operations.
As a motion controller that controls 24 real axes at the same time, multiple motion control modes, integrated rich ports, powerful hardware expansion capabilities, and friendly programming interface, the 15MC controller is bound to become the future motion control market. The mainstream choice.
Selecting the multi-axis motion controller DVP-15MC series can fundamentally solve the problem of multi-axis synchronization of the passenger car assembly line. Based on the PLCOpen2.0 standard motion control library, the system is more extensible and flexible. At the same time, the programmer is easy to use and meets the user control requirements. Not only completed the customer's intended goals, but also can significantly shorten the project development cycle, saving manpower and material resources.
The 45W MagSafe Power Adapter has a magnetic DC connector, so if someone trips on it, the power cord disconnects harmlessly, keeping your MacBook Air safe. It also helps prevent the cable from fraying or weakening over time. Additionally, the magnetic DC helps guide the plug into the system for a quick and safe connection.
