“…F. Dietrich proposed an assembly accuracy analysis method and a method for improving assembly accuracy to improve mechanical assembly accuracy. At the same time, this improved method is convenient for computer control and analysis, and is an effective means of elevating traditional methods to intelligent control methods [1]. Deepak Agrawal has designed a software for detecting assembly accuracy.…”

<p>This article focuses on the current situation of large assembly errors, easy omissions and errors in the mechanical assembly process. Computer vision is introduced in the assembly process, and visual images are used to estimate assembly errors, thereby improving assembly accuracy. To this end, through improvements to the neural network, the addition of attention and measurement mechanisms, the network’s ability to extract and distinguish features from assembly images has been improved. Finally, deep learning algorithms are used to estimate assembly features in the image. Finally, simulation experiments have shown that the algorithm proposed in this paper can achieve 94.7% improvement in assembly accuracy and error estimation accuracy.</p> <p> </p>

“…A key unique feature of the high-throughput ESC stacking is the feeding of the separator material and electrode sheets at a constant velocity, and the subsequent z-folding. Based on the derived kinematic relationship of z-folding by Glodde [46,47], the z-folding kinematic is considered idealized as a two-dimensional system, since the folding motions occur in one plane. The path-time diagram of one gripping system is shown in Figure 14 as an example for the reference format with 304 × 129 mm (length × width), a separator feeding speed of 500 mm/s and a circulation length of the transport system of 2500 mm.…”

What are the benefits of simulation-driven design and optimization of stacking processes in battery cell production? This question is addressed within the scope of the paper. This work proposes a method to reduce the effort for model-based design and optimization. Based on three case studies which originate from the development of high-speed stacking processes, this paper illustrates how the relevant loads on the intermediate products are determined with the help of the method. Subsequently, it is shown how the specific material models for battery electrodes and separators are identified, created and validated, as well as how process models are created and process limits are identified and optimized. It was possible to prove how process simulations can be used to minimize the effort required to validate developments and to efficiently determine optimized process parameters for a format and material change in a model-based manner. Consequently, more and more model-based processes should be taken into account during development and start-up in the future.
