Abstract: A process cycle time determination method includes: performing processing to obtain a first dataset based on production process data and attribute data of a line body of a production line; performing two-dimensional matrix conversion on the first dataset to obtain a first matrix when there is a missing value in the first dataset; performing filling on the missing value in the first matrix by using the K-nearest neighbors model and the chain equation model of random forest to obtain a corresponding filling value; filling the filling value in the position of the corresponding missing value in the first dataset to obtain a second dataset; and determining a process cycle time of the target station of the target line body in the production process of the target vehicle type based on the second dataset.

Abstract: An integrated module for forming, dressing and changing and an apparatus includes a primary mechanism, a forming mechanism, a dressing mechanism and a changing mechanism. The primary mechanism includes a mounting surface. The forming mechanism is configured to squeeze an electrode cap. The dressing mechanism is configured to cut the electrode cap. The changing mechanism is configured to remove or install the electrode cap. The forming mechanism, the dressing mechanism, and the changing mechanism are all provided on the mounting surface and are arranged at intervals from each other. According to the present application, the forming mechanism, the dressing mechanism and the changing mechanism are integrated on the mounting surface of the primary mechanism, thereby facilitating automatic switching between the dressing and forming functions, and thus the time required for manual operation and space occupation are greatly reduced.
