The modular manufacturing arrangement comprising several modules enables the automated deformation of material blanks into corresponding receiving troughs of the battery carrier, thereby effectively reducing the assembly effort and assembly costs during the manufacture of the battery carrier. The modular design of the modular manufacturing arrangement also ensures flexible expansion or repositioning of the individual modules of the modular manufacturing arrangement.

[0011] According to a first aspect, the disclosure relates to a modular manufacturing arrangement which is designed to automatically produce a battery carrier with a receiving tray for receiving an electric battery module of an electrically driven vehicle from a material blank, with a blank storage module which is designed to provide a plurality of material blanks, a deep-drawing module which is spaced apart from the blank storage module and is designed to deep-draw a material blank placed in the deep-drawing module in a deep-drawing process in order to obtain a deep-drawn receiving tray with a tray bottom and a deep-drawn wall with a flange circumferentially delimiting the tray bottom, a processing module which is spaced apart from the deep-drawing module and is designed to further mechanically process the deep-drawn receiving tray, and a handling robot which is designedto automatically remove a material blank from the blank storage module, to automatically feed the removed material blank to the deep-drawing module, to remove the deep-drawn receiving tray from the deep-drawing module after the deep-drawing process and to feed it to the processing module for further processing of the deep-drawn receiving tray.

[0012] This achieves the technical advantage that the modular manufacturing arrangement ensures a particularly advantageous production of a battery carrier.

[0013] In the modular manufacturing arrangement, the board storage module, the deep drawing module and the processing module are designed as separate modules arranged at a distance from one another, each of which performs specific functions within the manufacturing process.

[0014] The handling robot of the modular manufacturing system ensures that the material blank is automatically transferred from the blank storage module to the deep-drawing module, and that the deep-drawn receiving tray formed from the material blank in the deep-drawing module is subsequently transferred from the deep-drawing module to the processing module for further processing. The handling robot thus ensures efficient component transfer between the individual modules. This achieves a high degree of automation in the modular manufacturing system, enabling the production of a large number of battery carriers within a limited period of time, thus reducing assembly effort and thus assembly costs.

[0015] In addition, individual modules of the modular manufacturing system can be easily replaced. Furthermore, the modular manufacturing system can be expanded with additional modules, and / or the position of individual or additional modules within the modular manufacturing system can be easily changed.

By dividing the handling robot into two robot elements, in particular arranged at a distance from one another, an effective distribution of the transfer effort of the components between the individual modules can be made possible.
