Technical Field

[0001] The utility model relates to the technical field of electric core module manufacturing, in particular to an extrusion tool. Background Art

[0002] In the production process of battery cell modules, one of the key processes that determines the production quality of the modules is to neatly extrude and stack multiple battery cells to a predetermined length, and then further weld or rivet to fix them; when welding or riveting the end plates and side partitions of the existing modules, the tooling extrusion and alignment components can only move in a fixed length direction or a single width direction, and the component power source is fixedly installed at both ends of the module, and it is difficult to avoid riveting points or welding points for modules of different widths, and thus it is difficult to be compatible with modules of other widths; at the same time, there is a partition module. When riveting or welding the partition, the side alignment component needs to avoid the partition, resulting in eccentric extrusion force, and the side alignment component cannot be positioned according to the position of different partitions; in the actual production process using tooling, often one tooling can only complete the extrusion operation of one battery pack or one type and size of battery cell module, which frequently causes a large increase in costs;

[0003] Because the battery pack needs to passively match the differences in vehicle models, the module sizes and structural forms vary, which leads to different positioning and extrusion requirements for extrusion tooling in the module production process. Especially in the current highly competitive industry environment, it is very necessary to save production process costs and develop a low-cost, easy-to-operate compatible module stacking tooling.

[0051] Optionally, a single side of the installation base plate 11 includes two side alignment components (side alignment component one 4 and side alignment component two 5, or side alignment component three 6 and side alignment component four 7). For modules without a middle partition, one side alignment component is used on a single side to align the side cells of the module, and the other end can be used as a spare (that is, only one side alignment component is set on a single side of the installation base plate 11, and side alignment component one 4 and side alignment component two 5 are assembled into one, and side alignment component three 6 and side alignment component four 7 are assembled into one); for modules with a middle partition, two side alignment components are used on a single side to align the partition modules respectively, thereby avoiding interference or insufficient space during the welding or riveting process of the middle partition, while ensuring the verticality and parallelism of the sides of the module.

[0054] It should be noted in the present application that on one side of the length direction of the installation base plate 11 is an end extrusion component 2, and on the other side is an end extrusion component 2 3; both the end extrusion component 1 2 and the end extrusion component 2 3 are provided with an end extrusion plate and an end extrusion plate limiting structure; taking the end extrusion component 3 as an example, the end extrusion plate 31 can enable the module to exit in the opposite direction of extrusion after assembly is completed, which is convenient for the subsequent module lifting process and avoids interference between the hook and the module lifting hole; the screw rod 37 is used to adjust the extrusion stroke of the end extrusion plate 31 to prevent excessive extrusion and facilitate the determination of the position of the extrusion working position of the end extrusion plate 31.

[0055] The specific operating principles of this application are as follows:

[0056] The mounting base plate positioning pin holes 13 arranged on the mounting base plate 11 are installed on the trolley 12. According to the specifications of the module to be extruded, it is selected whether to install the module middle partition positioning component 12 on the base plate and to select a suitable module middle partition positioning component 12 to be installed on the base plate; this example is a module with 15 cells in a single row and a middle partition. For the convenience of assembly, the middle partition S2 needs to be placed on the module middle partition positioning component 12 for positioning, and then the module end plate S3 is placed on one side of the end extrusion component 2 for positioning. The single cells are arranged on the base plate in sequence, and after side alignment and extrusion in the length direction, they are welded or riveted to form a battery module;

[0057] When assembling the battery module, after the end extrusion assembly 12 moves to the working position along the direction of module extrusion, the end plate of the module is placed on the end insulating plate to realize the positioning of the module end plate, thereby completing the limit of one end of the module;

[0058] The end extrusion assembly 2 3 is different from the end extrusion assembly 1 2, and an end linear motion assembly 8 is added; the end extrusion assembly 2 3 is fixedly connected to the end slider 82; the end extrusion assembly 3 completes the positioning of the module assembly through the positioning hole and the quick latch and the positioning hole on the mounting base plate 11; when the battery module is assembled, after the end extrusion assembly 2 3 is positioned, the end insulating plate 32 corresponding to the module is matched, and then the end plate S1 of the positioning module can be installed; after the end plate S1 is installed, the end extrusion plate 31 can be driven to complete the extrusion of the module in the length direction, and the pressure detection display is used to determine that the extrusion operation of the predetermined module length is completed; at this time, when the end is extruded to a predetermined length, the side plates on both sides of the module can be installed by driving the side extrusion assembly one by one to rivet and fix the module cells, thereby completing the extrusion and stacking operation of the module;

[0059] In the side alignment extrusion of the module, it is necessary to consider the module length, width, presence or absence of a middle partition and the position difference of the partition. The corresponding side panels that require tooling, the extrusion stroke, and the position of the extrusion components distributed in the length direction of the module have flexibility, so as to achieve the compatibility problem of the side alignment mechanism. In order to solve the above compatibility problems, side alignment component 1 4, side alignment component 2 5, side alignment component 3 6, and side alignment component 4 7 are symmetrically arranged on both sides of the module; considering that the module is in the form of a middle partition S2, the single-sided side alignment component 4 and the side alignment component 5 are moved to the alignment work position, and after the required battery cells of the module are arranged and placed on the bottom plate, the symmetrical side side alignment component 6 and the side alignment component 7 can be moved to the work position, and then the module is extruded along the side alignment of the module width direction;

[0060] The side alignment component 1 4, the side alignment component 2 5, the side alignment component 3 6 and the side alignment component 4 7 are completely identical in structure. Taking the side alignment component 1 4 as an example, the side extrusion alignment of the module of the specified specification can be completed by switching the side insulation plates 42 of different sizes; the alignment extrusion work of the module of different widths can be completed by the screw rod 2 46.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
